Title: Image forming device
Inventor: SHIRATORI TATSUYA
IPC: G03G15/08
Filed: 1988-02-29
Abstract: PURPOSE:To prevent the starting of an operation in a condition when a developing device or a photosensitive drum is damaged or when a door is not completely closed by providing a closing inhibition part and a pulling-out and loading inhibition part on an operating handle. CONSTITUTION:The door closing inhibition material 42, which inhibits the closing of the door to a specified position when the developing device is not in operation is formed on the operating handle 41, and on the door 43, a projection 44, which protrudes inside is integrally formed. Therefore, when the developing device is in a non-operational position, the projection 44 abuts on the door closing inhibition material 42, causing the door 43 not to close up to the specified position, and because of that an electricity source switch 45 is not turned on, and the image forming device does not operate. Further, since the handle 41 acts as a material to inhibit the pulling-out and the loading of the developing device, when the handle 41 is turned and the developing device 22 is positioned in an operating position, the handle 41 is positioned on the pulling-out path of the developing device, preventing the pulling-out of the developing device. Thus the damage of the developing device or the photosensitive body, and the danger at a time of operation can be prevented.
