摘要： A line scanning type optical printer device which forms a picture by making relative motions while the device emits light toward a sensitive material, and uses LEDs as a light source. On the mounting substrate of the LEDs, each pair of LEDs of the same color is symmetrically arranged with respect to the center of scanning lines. In addition, the lead-out lines for power supply to the LEDs are also laid symmetrically. Moreover, the LEDs are mounted on the mounting substrate together with light shielding members which shield light from the side faces of the LEDs.

摘要： A photosensitive element (19) has on its photosensitive surface side a non-photosensitive portion having a width D1 extending from the front end to ward the rear end in the transfer direction, and a non-photosensitive portion having a width D2 extending from the rear end to ward the front end in the transfer direction. The region where light is shone to the photosensitive element by an optical head is located between a point a distance D1 away on the upstream side in the transfer direction and a point a distance D2 away on the downstream side in the transfer direction from the center of the transfer roller (5).

摘要： Even if an unexpected load is applied to the optical head of an optical printer while the optical head is scanning, an LED and a liquid crystal shutter are driven synchronously with the position of a photosensitive paper to avoid the distortion of the image. A rotary encoder (320) is provided on the rotary shaft of a motor (310) for moving the optical head (100), and the driving timing of the LED (110) and the liquid crystal shutter (150) is synchronized with the output of the rotary encoder.
