Title: Illuminator
Inventor: HANADA SHINJI
IPC: G03G15/043
Filed: 1988-10-31
Abstract: PURPOSE:To prevent deterioration in blank exposure quantity to an image carrier by keeping an incident angle and a reflection angle almost the same through the use of a reflecting member with an arc-shaped reflection plate which rotates around a rotating axis even when blank exposure is converted into image exposure. CONSTITUTION:The angle on which blank light from a light source for blank exposure 12 that is arc-shaped, centered around the axis 4, is made incident and the reflection angle are kept almost constant when the reflecting plane 13a of the reflecting member 13 rotating around the rotating axis 14 is rotated to convert blank exposure into image exposure through a mirror 5 and vice versa. Thus, deterioration in blank exposure quantity to the image carrier 7 is prevented. Moreover, fogging and a black stripe never arise at the top of a picture and its bottom space, and a wasteful consumption of developing toner can be suppressed. An illuminator equipped with plural reflecting planes that turn around the rotating axis and possess fixed length for its specific angle can provide a similar effect.
