Document scanner having scan carriage stowed in secure location for transit.

A scanning device scan carriage 12 is located within a housing 18 and moveable along a displacement path. A carriage drive belt 40, having a belt tensioning system 44, moves the carriage 12 along the displacement path. When necessary, for example when the scanner device is to be transported or shipped, a control system acts to move the carriage 12 - via motor 42 - to a stowed position 48. The location of this stowed or secure position 48 is such that a force exerted on the carriage 12, along the displacement path, is not directed or transmitted to drive belt tensioning system 44. Specifically, in the stowed position 48, forces on carriage 12 are resisted respectively by (a) stop 54 and (b) the resistence offered by drive motor 42. Thus, when the carriage is stowed, the tensioning system 44 is effectively isolated from forces on the carriage 12.

Systems and method utilizing a laser beam to produce artwork for printed circuit boards. The laser beam is modulated in accordance with the artwork and scanned across an output medium to form an image of the artwork. The scanning means includes a reflector rotating at a constant rate. The resultant non-linearity of the linear velocity of the beam as it scans across the medium would cause corresponding non-uniform exposure of the medium. The intensity of the beam is thus varied to compensate.

METHOD AND APPARATUS FOR REGISTERING COLOR SEPARATION FILM

A method and apparatus for registering the halftone color separation films used in color picture processing. A digital picture is taken of two register points on each separation film, and the pictures (which may contain register marks) are analyzed by algorithmic processes in order to calculate the movement necessary to register the halftone picture details (or register marks). Based on the calculations, the films are punched to provide a pair of register holes in each film at locations which result in registration when the register holes are aligned on register pins during the final reproduction process. The algorithmic process involves determining the halftone screen angle, average interdot spacing and fractional area occupied by each halftone dot within its halftone cell and using this data to construct a continuous tone picture. Interpolation techniques are used to interpolate the continuous tone picture to a registration picture which is a 150 line screen picture square with the raw ...

IMAGE SCANNER MEASURING THE MOTION OF READER AND LIGHT SOURCE ON A TEST CHART

A scanner is so arranged that a quantity of light reaching a CCD sensor can be kept constant with a change in reading position. In cases where a light source and a reading optical unit are driven independent of each other, variations in feed amount inevitably occur. To deal with it, a test chart of a specified length is first read to measure amounts of movement of the light source and the reading optical unit. Then, the reading optical unit is moved by a predetermined amount. The light source is moved to effect a correction based on the amount of movement initially measured. Then, a one-line reading process is carried out to scan an image on a document.
