Claims

[Scope of Claim for Utility Model Registration] (1) In an image forming apparatus using an electrophotographic process, which is equipped with and uses a replacement unit provided with a rotatable handle, the handle is provided with a member to be detected, and the replacement unit is provided with a member to be detected. A detection means for detecting the member to be detected is disposed at a position corresponding to the member to be detected when the unit is installed in the image forming apparatus and set by rotating the handle to a predetermined storage position. Features: Replacement unit detection device for image forming apparatus. (2) A replacement unit detection device for an image forming apparatus according to claim 1, wherein said detection means is a photo interrupter, and said installation of said replacement unit and setting of said handle is detected by entry of said detected means into a gap of said photo interrupter. . (3) Claim 1, wherein the detection means is a switch, and detects attachment of the replacement unit and setting of the handle by contact of the detection means with the switch.
Replacement unit detection device for image forming apparatuses.
