タを動作させるようにした、 カバー開閉検知機構。[Scope of Claim for Utility Model Registration] The main body of the apparatus includes a developing unit cover that can be opened and closed, a cleaning cover that is slidably provided on the developing unit cover, a fixing unit cover, and when any of the covers is opened. In an electrophotographic printer having a detector that sometimes outputs a stop condition signal, (a) one detector having an actuator with a return spring is provided in the main body of the device, and (b) a detector is provided in the fixing unit cover. , an L-shaped lever is pivotally supported at its bent portion, and one end of the lever faces the actuator of the detector when the fixing section cover is in a closed state; (c) inside the developing section cover; , an arm is pivotally supported at one end thereof, and the other end is provided so as to face the other end of the lever of the fixing section cover in the closed state when the developing section cover is in the closed state; A plate is provided in the cleaning cover that presses the other end of the arm toward the other end of the lever when the cover is closed, and (e) the plate presses the arm when all the covers are closed. A cover opening/closing detection mechanism, wherein the lever is pressed in the direction of the lever, and the lever is rotated to operate an actuator of the detector.
