Abstract (en)
[origin: EP0931667A2] An optical writing printer head which can accomplish at the same time the miniaturisation and lower cost of a printer head and the assurance of the resolution of print pixels. In a printer head where an LED 2 for emitting blue light, and LED 3 for emitting green light, and an LED 4 for emitting red light are mounted on a substrate 1, the whole is covered with a cover 5, and the exposure dot sizes are restricted by apertures 6, 7, and 8 corresponding to the respective LEDs and provided in the cover 5. The sizes of the apertures depends on the colour of the light source with which each is associated. <IMAGE>
