Optical imaging recording system for performing image recording by focusing modulated light beams |
摘要 |
An optical beam recording device for performing image recording by focusing a plurality of light beams modulated according to an image signal through a focusing optical system onto a photosensitive member, including a light source having a plurality of arrayed light emitting portions for emitting the plurality of light beams; a light detecting device located at a given position for detecting a detecting light beam of the plurality of light beams; and a control device for controlling a focused condition of the plurality of light beams on the photosensitive drum according to a result of detection of the detecting light beam by the light detecting device. With this arrangement, shift of a focal position can be detected with high accuracy without increasing a response speed of the light detecting device and inviting the complication of configuration.
