In the present invention according to in the embodiment described and of attached drawing, may be conveniently disposed tin the same number refer to components without special assessment equal. As well as, to assist in the understanding of a wording for description is given of the present invention, the same component may be conveniently disposed tin even if necessary different number disapproval.

Figure 2, in the embodiment according to one of the present invention, security paper to the mobile communication terminal device including a laser printer print plower based on number (100) for visually representing one example of the schematic configuration are disclosed.

Also illustrated 2 laser printer (100) is, generally known apparatus of publicly known components (laser scanning unit, toner, d bell [lep roller, photoreceptor drum assembly, discharge lamp, fuser, supports a discharge for mechanical components and case, the paper to printing operation number plower printing number control unit (101) or the like) in addition to the, to a given method and/or security level according to printing paper number additionally plower security number control unit (20) on, paper supply for an inductive (inductive) containing such conductive manner it is detecting an inductive sensor (21) consists of including.

In addition, said laser printer (100) is, supports before pass from a light sensor for sensing paper (22) on, said laser printer (100) tray (102) can be open sensing closing sensing sensor (23) on, the driver speaker can be protected when necessary (24) further comprises consists of.

On the drawing, said an inductive sensor (21) on said optical sensor (22) in the extension direction of the paper is juxtaposed but, this, in the embodiment according to for displaying the one or more components is received, preferably, said two sensors (21, 22) oriented transverse to the side in the direction of travel of the paper is disposed thereon. Since, said an inductive sensor (21) a detection signal outputted from the one section (where, 'effective section' RM paper on a P signal interval detected by means) advantageously identifying's oldest. As well as, said amount sensor (21, 22) is, positioned away from each other along the traveling direction of paper which effective section can be specific. In which case, said security number control unit (20) is, supplied to the speed at which the paper drum assembly indicated-spaced spaced apart from each other, said an inductive sensor (21) is detected from the plotter is equal to valid data present in the signal.

In the embodiment in the present invention according to another, said optical sensor (22) and does not exist, so that the output signals from the conventional printer the paper sensor (feed sensor) may be disclosed. When the, ON signal output after said feeding sensor, said printing paper is an inductive sensor (21) when the time difference from the point just below both doesn't, said an inductive sensor (21) is detected from the plotter is equal to valid data present in the signal.

In the present invention according to one in the embodiment, said security number control unit (20) includes said laser printer (100) without mounted within, disapproval is attached outside casing separately from printer to printer.

Said optical sensor (22) is, current sensor detects the amount of light is irradiated with light are disclosed. Generally, the optical because white reflection print paper, said optical sensor (22) of paper the number of e.g. HIGH output current state with each other.

Said an inductive sensor (21) is, drum assembly comprised the paper is supplied to generate a magnetic field direction sensor for detecting if the change in the intensity of magnetic field generating his own are disclosed.

Said laser printer (100) tray (tray) (102) from an exhaust roller, as also illustrated 3, such as conductive fine piece thread piece (30a) are randomly to the entire distributed security paper (30) back, said an inductive sensor (21) generated from the magnetic field to induce an eddy current (eddy current) to 1 difference and fine piece to be coated paper. And, the SnO 2 derived by an eddy current magnetic field is generated, said an inductive sensor (21) and influencing the magnetic field intensity difference generated by 1 and is connected to the other.

The, said an inductive sensor (21) is, generates variations in that its intensity of magnetic field along logic unit is performed without signal level (e.g., if there is a HIGH to variations in a magnetic field, the areas are not LOW) security number as said control section (20) applied.

Then, said security number control unit (20) is, the applied signal level changes when the paper (paper or part of) the current paper supply (or paper region) as illustrated in fig. 3 is demodulated fine pieces are distributed security paper (or security documents portion) in determined that whether, if electrons recognize, said printing number control unit (101) according to usual number operate said tray (102) suspension of the current paper supply from Image forming and n is an integer.

One of the stopping sheet printing method, said security number control unit (20) interruption signal (PSS) printing said printed a number control unit (101) is applying. Said printing number control unit (101) includes printing said interruption signal is applied, and stopping to conventional method according to printing paper, paper with a discharge for the mechanical interruption of the further operations in addition to be coated. For example, paper jamming (jamming) causes state.

The other sheet and stopping the printing method, a laser printer is equipped with a specific output stage voltage (e.g., developing voltage) by turning off the driving voltage terminals are disclosed. The voltage is off, through a suitable electrical connection can be made by printing said interruption signal. A considerable, being produced during operation is interrupted and the discharge of the paper stop with each other.

On the other hand, said security number control unit (20) is, when stopping the printing decision, said speaker (24) driven by an, enters a protected sufficient attention of voice output substrate. This, as current effect on printing paper is attempted, the member the same space, when in the network can recognize the personnel and the like are disclosed.

In hereinafter, said security number control unit (20) according to printing operation of the interruption determination process and with an identifier for the paper is greater than specifically described as follows.

As also illustrated 3, conductive fine piece (30a) global security documents are distributed randomly (30) is in contact with the water supply path while said non-contact approaches within a predetermined distance or along an inductive sensor (21) when through, due to the irregular distribution of fine pieces, of paper over, eddy currents generated by magnetic field inductive sensor or said eddy current derived so 2 difference (21) changes (i.e., threshold or more change) by magnetic field 1 difference does not necessarily cause.

The, it became work normally number 3 also illustrated as security paper (30) in operation is detected, said an inductive sensor (21) outputted by, as also illustrated 4, to fine piece part due to non-synchronization with width pulse group recognized by any intervals (40) to form with each other. Examples of Figure 4, eddy currents when a level of said magnetic field forming HIGH fine piece transmissions by an inductive sensor (21) signal outputted from the waveform of the example assumes are disclosed.

The security paper so that even when the detection signal is output state signal, said security number control unit (20) is, said an inductive sensor (21) change of the effective section (section is, aforementioned was as said optical sensor (22) by a detection signal from the c1.) which are transitioned to the low (LOW) to high (HIGH) (or vice versa can go down) is the predetermined reference number (T_N ) (E.g., 2) and the exhaust roller is greater than the current security paper printer, otherwise general papers to decide.

Said predetermined reference number (T_N ) 1 is entirely but may have, such as an electromagnetic wave noise by mechanical movement of the paper by said discharge/such as the inductive sensor (21) is n-methylpyrrolidone and pouring, the number of 2 or more reliability of paper discriminating said reference number (T_N ) Preferably specifying. However, when the papers may be determined reference or all security paper is, not too large as said reference number specifying the appropriate preferably.

In the present invention according to one in the embodiment, said reference number (T_N ) Is, said security number control unit (20) can be set according to a security level set in a depending. The higher the level security for the number of the reference channel with the reference value of the other. Security level for the printing operation according to carry number having posted cas latency and etched.

Said security number control unit (20) is, whether a paper feeding and is rotatively installed if, as for the aforementioned current paper causes not print operation.

Typically, laser printer or the like, printed papers (drum assembler of Figure 2) is reduced at a point number chamber and started up point-to-point of path length (201) (hereinafter, '([...]) electric feeding to' soap without.) tended to put etc. exhibit very short. The mechanical malfunction since the main gear room for reducing the glass are disclosed.

The temperature detector, the previous embodiment as shown in the example, according to the direction of conveyance of the entire length of the paper (typically paper longitudinal length, in the case of A4 paper 297 mm) over said an inductive sensor (21) detected in the pulse from the number of security paper is printed and the resultant part judges whether the beginning in order to, feeding into a longitudinal length or more field should at least printing paper. However, the electric field need to be formed in the stopper short collision with each other.

Thus, in the embodiment in the present invention according to another, feeding into short field, security documents is made whether paper is automatically has been or partially secured region (i.e., a region which is a fine piece) is not even during printing in paper end portion determined as current paper portion secured region to determine whether or not continued low journey paper end detection, sensor for detecting the number during printing operations on or before subjected to substrate. In the embodiment detailed hereinafter in the greater than 2000.

In the in the embodiment, printing said paper tray (102) when feeding from, said security number control unit (20) is said optical sensor (22) detecting sheets from detection signals of the reflected lights, as also illustrated 5, said an inductive sensor (21) detected in the signal outputted from the corresponding end point (51) is one, a method for producing a piece when not detecting paper output value (hereinafter, 'LOW' value is acquired other.) time lasts (50) is, designated to limit time (T_LIM ) Reaches or exceeds, said security number control unit (20) is non-security paper current paper portion (chamber do not include the number of the immediately preceding region) region (hereinafter, 'secure area' is provided to each other. a) recognizing and other (S51). The secure area is recognized, said security number control unit (20) has, in a distal end portion or during printing start printing-related operation under current printed in such a way described above immediately before interruption of the substrate.

Said limit time (T_LIM ) Is, said laser printer (100) paper feeding speed and printing paper type (letter, such as A4) defined on the basis of longitudinal length be made, for example, 1/10 of papers, 1/5 or 1/8 can be polarized light beam to a transfer position corresponding to the section. I.e., feeding speed v_FEED And paper length P_L The it, 0. 1 * P_L /V_FEED , 0. 125 * P_L /V_FEED Or 0. 2 * P_L /V_FEED Said limit time is decided to be used flow tides.

Said limit time (T_LIM ) To the lower end of short, due to the irregular distribution of fine pieces and dense fine piece is also normal in security paper is printed can be made partially unrecognized of interruption in the audio signal. If so too is set to be longer surface, techniques of efflux of malicious suspension setup menu by a user fat disapproval. E.g., said tray (102) to a circular shape and is equipped with a security paper out portion, such as in Figure 6 general paper, or thin tape or the like by one printed paper lining adhesive number (60) (in this way security paper to paper to derive whether 'Gabor into paper' hereafter referred to as.) are formed in said printer (100) can be made printing may be disclosed. Also illustrated 5 a Gabor in paper (60) is, unrecognized a duration of fine pieces, said limit is set to be longer the time (T_LIM ) Exceeds by fine piece before recognition security paper can be. Whether such induction is printed through a Gabor in paper (60) security documents in part (61) is a stand-alone number, security documents like device is fitted to the outlet for sensing the gate operates in pass number like door can be disclosed.

The, said limit time is, made into whether malicious inducing even printed contents key technology as a Gabor paper, paper fraction of the printed portion is that the vertical width to such an extent that the printing corresponding to webcasted content (example threshold time values above, paper 10%, 12. 5% or 20% longitudinal width as formed by the substrate.) to provide a value the c1.

And, in the in the embodiment, only the start of the duration of time exceeds said limit LOW paper as well as determining whether, said an inductive sensor (21) after fine piece according to HIGH level output from detection of fine piece distribution whenever LOW mesh is irregular transitions, the transition time and the duration of time exceeds said limit is checked whether LOW state from, identified as exceeding a specified threshold time prior to the current printing interruption of the recording operation to be coated.

The detection signal level of every transition items of an LOW level duration of concern, such as manner illustrated 6 also, single transverse section as a part of security paper (or a portion of transverse section) combination on top of a paper print paper and paper printed by using authentic can be brought to a stand-alone part number after a Gabor into printing content thereof can prevent outflow to a security paper. A signal level detecting durations of said time limit or the LOW level every transition items of an information and is connected to the selectively interrupting the printing, a printing paper only whether it can be completed without inducing transverse section because interrupted during the normal printing are disclosed.

In the present invention according to one in the embodiment, compared against the limit time duration of LOW from sheets, LOW HIGH detection signal after comparing the limit time duration time in transition to a different value is set as a disapproval. Preferably, the latter limit time is longer than tft3. electron limit time value. I.e., one printed paper once the fine pieces are detected on the basis of the subsequent non-secure regions which are adapted for discriminating reference is relieved therefrom.

And, a criterion is applied to the aforementioned manner limit time is, according to the security level after describing whose values can be adaptively varied. For example, level security printing condition (i.e., current printing environment situation) according to adaptively to the control surface, manipulate the limit value (of Figure 8 81) shorter time is altered. I.e., high security level discriminating it into a different non-secure more than the criterion which, this, vice versa from becoming stringent security paper region have been further based means other. Adaptively adjusted level security for the etched carry particular examples.

On the other hand, in the present invention according to one in the embodiment, said an inductive sensor (21) not each detection signal said plural supports a single security number control unit (20) is applied to the third may be filled. In the in the embodiment, a plurality of inductive sensor with respect to each other at equal intervals in the direction of travel of the paper is a horizontal disposed thereon. The plurality of inductive thereby ensuring that, when a single inductive sensor with, such as the inductive sensor 7 also both path (71) portion of security against paper combination tantalum condenser region (72) that the printing can be prevented.

Even when used for a single to an inductive sensor, its location through which a motor by any manner, such as Gabor in the art paper also 7 into paper (70) for blocking printing to disapproval.

In the embodiment according to an inductive sensor provided with a plurality of aforementioned when, according the currently established plurality both security level, selects only one or some use a plurality or disapproval. Wherein, 'use' meaning that the light output from a light detection signal, that is used to identify whether the non-secure area. If the lowest level security, as also illustrated 8, single sensor but, both or portions thereof of high level security along the magnetic and degree can be sensor (82).

Figure 8, security are to adaptively setting, applied identification security documents mentioned parameters {limit time, number of used an inductive sensor (or detection signal)} is shown as combined with the control table, set level security 'on', 'of', according to a house which forms an 'to' 3 are disclosed. In the embodiment of prior pipeline, whether a security paper inverts said variable and a counterflow of water contained therein.

If a plurality of an inductive sensor, the signal detected from the sensors with respect to each described above in such a way non-secure operation sensor for detecting the number of projected to etched. I.e., using one of a plurality of detection signal from signal for discriminating it into a non-secure printing sheet button is equal to stopping.

According to the security level, e.g., if the current level of security than, detection signal of the angle sensor even if a plurality of an inductive sensor, as also illustrated 9 OR operation (90) made with a summation signal (91) a, the current paper portion corresponding secure area is employed for the determination of the portable terminals may be filled.

Along the way the currently established security level sensors, when the sensors 2 of example described, level security when the 'on', the sensor 2 is detected from signals individually for each signal, i.e. are independently non-secure area for discriminating whether or not, when the 'one' level security, sensor 2 and either be selected, level security when the 'a', as detected signal value 2 also illustrated 9 OR signal obtained (91) a, non-secure region is determined that whether engaged are disclosed.

On the other hand, secondly the security level is operated, said laser printer (100) with a user interface (e.g., keypad adsorbing) number through said printing control section (101) after said security number input control section (20) can be set by delivered. Or, security level unit for the establishment of distinct input means and said security number control unit (20) may be set directly disapproval. And, the setting information about a security level, said printing number control unit (101) by said laser printer (100) may be displayed with display means (adsorbing), said security number display on an to the operation control section (20) much by disapproval.

In the present invention according to one in the embodiment, the n-operated security level said printer (100) or may be set by an operator of a passively, disapproval automatically. In respect to the automatically determined level security method hereinafter detailed as follows.

In the present invention according to one in the embodiment, said laser printer (100) code of inputting security paper (i.e., said tray (102) security paper blue) grade according to said level security the c1. Wherein, the means by which security documents grade, fine pieces of paper in conductive, ratio, determined by density and/or their distribution. Conductive, ratio, or the higher the density, the larger is the c1. equalization distribution high-grade security paper. Said security number control unit (20) is, said printing number control unit (101) or delivered by separate input means inputted through high grade security paper securely level is set higher when the front and rear, and a low security level according to a low level when the vscl1.

Security documents according to a security level by lowering the low grade when they (the security level from the condenser, as discriminating it into a different non-secure the aforementioned criterion enhanced substrate. I.e., fulfilling a given up on to secure area formed on determined other.), security paper in spite of non-secure region frequently determined printing unit has a lower potential to be coated may be brought about and interrupted can be protected. As well as, high security paper rating using the security level thereby automatically to the control, is completely ensured security for printing are disclosed.

In the embodiment in the present invention according to another, said tray (102) has come undone when level security closed automatically change received signals. Said tray (102) the closing said open/closing sensing sensor (23) is identified from signals from, said security number control unit (20) is, said tray (102) has come undone for opening and closing, since then a preset certain time highest security level for automatically placing the substrate. The newly closed tray, which is filled with new printing paper was an, printing paper is newly filled, non-secure papers may be made into paper-free region may be whether a Gabor since, whether a dielectric window is equal to the possibility to automatically the highest level of security.

Said tray (102) from another after said closed once, said security number control unit (20) is the highest level of the automatic before the level of security, or intermediate tracked returns to the level substrate.

In the present invention according to one in the embodiment, said tray (102) from another after said closed even before, said tray (102) branched feeding from Image forming operation, a number of predetermined reference number or more, such as described above by passing security inspection without interruption after the printing on the basis of the, automatically setting the highest level of security before returns to the level substrate.

In the present invention according to one in the embodiment, said laser printer (100) is capable of manual paper-feeding ports if and print paper sheet feeding, said security number control unit (20) is, supplied to the drum assembly to determine whether the paper is restricted by a supply line supplied from the paper tray by selecting a separate sensor and, said tray (102) when the paper is supplied the currently established security level through applying a security paper examined whether and, if manual paper-feeding through the inlet opening when it is supplied by applying the highest level of security paper check security paper substrate. I.e., subjected to manual paper fed, is a region of the most stringent criteria examined whether by applying security paper to be coated. And, manual paper-feeding through the paper of individual is discontinued and, again tray (102) is supplied to the highest level of security papers ejected when changed filtered and returns to the level, the level defined by reference based on security paper examined whether region to be coated.

Hitherto, an printer paper supplied paper found found security paper according various method relative to the number plower Image forming operation, laser printer applied e.g. specifically are described. However, the principle of the present invention as to whether a security paper according to printing number [e[e] east identification and general outline according to techniques region it is small, the air from the type of printer (laser, inkjet or the like) can be applied, in addition to printing paper such as copier as well as also can be applied to all printing device. The, printing device used in regardless what applications found, object of the present invention is based on the claims including the scope of the invention should range it will to belong.

The present invention is described in the embodiment heretofore described in the embodiment to method such as an effect on construction with various compatible each other if is generated according to a, selectively coupled pivotably to each other in a variety of ways embodiment.

Or more, the aforementioned of the present invention in the embodiment are, for the purposes of example that the disclosure, if one skilled, the technical idea of the present invention disclosure and claim appended hereinafter to technical range, another various in the embodiment are improved, change, additional capable of replacing parts or will.
