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.
