Title: Electrophotographic device
Inventor: OGINOYA YOSHIAKI
IPC: G03G21/16
Filed: 1995-12-29
Abstract: PROBLEM TO BE SOLVED: To prevent a light shielding shutter from being vibrated with a shock even when the shock is given to a maintenance cover in a state where the maintenance cover is closed and the light shielding shutter is opened, thereby preventing an optical scanner from being vibrated and obtaining excellent image quality. SOLUTION: When the maintenance cover 44 is closed, the actuation projection 72 of the cover 44 abuts on and is engaged with the lever for opening 58 of the light shielding shutter 54, and the shutter 54 is pressed and moved toward an opening position from a closing position with the closing operation. When the shutter 54 exceeds a neutral position and reaches an opening direction side further than the neutral position, the energizing force of a coil spring 68 acts to energize the shutter 54 to the opening position. The projection 72 is separated from the lever for opening 58 and a lever for closing 60 at the opening position of the shutter 54. The same operation is performed in a reflection mirror part shutter 74.
