Zusammenfassung: | PROBLEM TO BE SOLVED: To prevent damage to a switch which interlocks with opening/closing operation of two doors, even when the doors are closed strongly or pushed in excessively.SOLUTION: A switch 50 is fixed to a device body. An image forming apparatus includes: an arm 61 which interlocks with two doors to be opened/closed, turns on the switch 50 when both two doors are closed, and turns off the switch 50 when at least one of the doors is opened; and a switch pressing member 62. The switch pressing member 62 includes a projection 62B and an elastic folding section 62C. The switch pressing member 62 is biased toward the switch 50 when a second door is closed, to start the switch 50 via the elastic folding section 62C and the projection 62B. The elastic folding section 62C prevents damage to the switch 50.
【課題】2つの扉の開閉動作に連動して切り換えを行うスイッチを備えた構造で、扉を強く閉めたり過度に押し込んだりしても、スイッチに損傷が生じないようにする。【解決手段】スイッチ50は装置本体に固定する。2つの扉の開閉動作に連動して、2つの扉の何れもが閉状態のときにスイッチ50を通電状態とし、少なくとも何れかの扉が開状態のときにスイッチ50を非通電状態とするアーム61及びスイッチ押し部材62を有している。スイッチ押し部材62は、突出部62Bと弾性を備えた折り曲げ部62Cを有している。スイッチ押し部材62は、第2の扉を閉めたとき、スイッチ50側に付勢されて、弾性を備えた折り曲げ部62Cと突出部62Bと介してスイッチ50を作動させる。弾性を備えた折り曲げ部62Cによってスイッチ50の損傷が防止される。【選択図】図7 |
