PURPOSE: To switch the diameter of a laser beam converging on a photosensitive body, and to execute the printing of different resolution. CONSTITUTION: When high resolution recording is commanded, a control part 18 turns liquid crystal 16 into a transparent state without applying a voltage to the liquid crystal 16. Therefore, the laser beams outgoing from a semiconductor laser 11, pass without being converged on the liquid crystal 16, and are converged by a hologram lens 12 and a hologram disc 13, to execute a high resolution exposure having a small dot diameter on a photosensitive drum 15. On the other hand, when low resolution recording is commanded, the control part 18 applies the voltage to the liquid crystal 16, to form a diffraction pattern. Consequently, the laser beams outgoing from the semiconductor laser 11 are converged a little by the diffraction pattern formed on the liquid crystal 16, and the converging in more front side than that of the high resolution, is attained. Thus ...

PURPOSE: To decrease the number of components and to obtain a compact, small-sized reader by splitting read light and scattered reflected signal light by the scanning of a light beam through an optical system with image formation characteristics which forms an image of a beam having one peak in a beam pattern having plural peaks.

This peak 111 is scattered and reflected by the scanning surface (e.g. bar code) 9, its reflected scattered light 115 is used as the signal light, and the necessary peak 113 is cut by a mask 27. The signal light 115 travels backward to the two-point image forming element 25 and part 115b of it is image-formed at a point different from the light source ...

PURPOSE: To miniaturize the optical deflector and to reduce its cost by providing a space optical modulator whose refractive index is varied by the heat of a heating means, controlling a heating temperature, and varying a refractive index distribution. CONSTITUTION: A heater 13 being a heating means and thermoplastic 11 being a space optical modulator are provided. In front of the plastic 11, a reflected film is brought to coating, and in front thereof, a half mirror is placed at the angle of 45°. As a result, incident light from the left direction is reflected toward the reflecting surface of the plastic 11, and transmits through the half mirror. In such a case, when the plastic 11 is brought to temperature control by the heater 13, as for the plastic 11, the refractive index distribution is varied by its expansion. Therefore, without using a mechanical driving part, the direction of light is controlled, and a motor having high accuracy becomes unnecessary. In such a way, the number of ...
