摘要： An optical printer has an optical head (100) which has a built-in LED light source (110) is moved relatively to a photosensitive paper (500) and allows the light source to emit a plurality of color lights from LEDs at predetermined time intervals so as to project the lights on the photosensitive paper at predetermined intervals. The image pitches P of the color lights are approximately equal to an integral multiple of the maximum exposure distance D.

摘要： An optical printer which exposes photosensitive paper (500) at a preset timing using light from a light source (110) moving relatively to the photosensitive paper (500) and based on image data comprising pixels having a plurality of gradations which linearly vary from a low-color-density minimum gradation to a high-color-density maximum gradation, wherein an area gradation is effected by adjusting an exposure distance to form a gradated image on the photosensitive paper (500). A gradation does not change in proportion to an exposure distance over a whole range but changes non-linearly.

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).
