Title: Optical writing device
Inventor: TAKEYAMA YOSHINOBU
IPC: H04N1/04
Filed: 1991-10-23
Abstract: PURPOSE:To suppress the deterioration of an output image due to the photosensitive body exposure by a flare light due to the main scanning synchronizing signal generation outside an image writing range and the light emission of a light source for recording for the light emitting output control. CONSTITUTION:At the time of waiting before the writing is started, a light source for recording is light-emitted outside an image writing range and the light emitting output control and the main scanning synchronizing signal generation are performed. Until a writing starting signal S is generated, a light emitting level signal S1 which becomes the minimum light output is outputted by a light emitting level instructing means 8 and a light source for recording is light-emitted. Thus, even when a waiting condition becomes long, the influence of a flare light to the photosensitive body is minimized, and from the time of actual writing after the writing starting signal S is generated, the light emitting level signal S1 performs the light output of the desired level.
