Title: Electrophotographic image forming device
Inventor: YOKOYAMA KATSUNORI
IPC: G03G21/18
Filed: 2001-01-26
Abstract: PROBLEM TO BE SOLVED: To improve the operability of an image forming device to/from which a processing cartridge positioned by being oscillated after being inserted into a device main body in parallel with a photoreceptive drum is loaded and unloaded. SOLUTION: The process cartridge B is loaded and unloaded to/from the device main body by being led by guide rails 101 and 102 at an attachable position P1. The projected shaft 303 of a cartridge is supported by a cam 103 on a rear side to which it is inserted, and next, the guide 301 of the cartridge is disengaged from the guide rail 101. When a rod 213 is pushed in, the cam top part of a plane cam 212 is pushed and a tapered cone 210 is pushed, so that the locking of an arm provided with the cam 103 is released. When a lever 110 is turned from a position PL1 to a position PL2, the cam 103 of an arm end fixed at a shaft 100 descends, so that the cartridge B is set at a printing feasible position P2.  Then, since the cam bottom side of a cam face 212a which is the spiral face of the plane cam 212 is rotated to the position of the rod 213, the rod 213 is moved to the cam face 212a by spring force and enters the inside of the lever 110, so that it is not pushed.
