An operating member that is disposed on the upper body side and that swings the engaging portion by a predetermined angle in a direction different from the split opening direction of the upper body and in a direction that opposes the urging force. When the joint portion is swung by a predetermined angle, the engagement with the engagement concave portion can be released, and the safety is achieved by facing the one engagement portion at the engagement position with the engagement concave portion. A switch is arranged, and the engaging part is swung against the biasing force via the operating member. When allowed, prior to swing to the disengaged position with said engaging recess, is proposed an image forming apparatus, characterized in that the the safety switch is configured to be actuated.

可能となる。Further, at the time of closing operation of the upper main body, since the engaging portion is elastically biased in the engaging direction and faces the safety switch at the engaging position with the engaging recess, With one operation of closing the upper body, the engaging portion and the engaging recess are automatically engaged by the elastic force, and the safety switch is turned off by the engagement, and power is supplied to various electrical components in the device. It will be possible.
従って、上部本体閉塞時においても開放時においても、
いずれの場合も操作上の煩雑さからの開放される。Therefore, whether the upper body is closed or opened,
In any case, the operation is free from complexity.

イッチ14をONし、装置内各種電装部品への電源供給が再
開される。Then, due to the blockage, the switch actuating portion 23b on the front side of the front end of the operation lever 20 presses the actuator 14a to turn on the micro switch 14, and the power supply to various electric components in the apparatus is restarted.
「発明の効果」 以上記載した如く、本発明によれば操作部材の揺動操作
という一の動作で安全スイッチによる電源供給阻止と、
本体間の係合解除、上部本体の分割開放を順次行うこと
が出来、而も上部本体の分割開放前に確実に前記安全ス
イッチが働く為に、操作の簡単化と一層の安全確保を可
能ならしめることが出来る。[Advantages of the Invention] As described above, according to the present invention, the power supply is blocked by the safety switch by one operation of swinging the operating member,
The disengagement between the main bodies and the divisional release of the upper body can be performed sequentially, and since the safety switch works surely before the divisional release of the upper body, it is possible to simplify the operation and ensure further safety. Can be tightened.
又本発明は上部本体の閉塞動作により自動的に係合部と
係合凹部が係合し、且つその係合により安全スイッチが
OFFし、装置内各種電装部品への電源供給が可能とな
る。Further, according to the present invention, the engaging portion and the engaging recess are automatically engaged by the closing operation of the upper body, and the engagement causes the safety switch.
Turns off, and power can be supplied to various electrical components inside the device.
従って、上部本体閉塞時においても開放時においても、
いずれの場合も操作上の煩雑さからの開放される。Therefore, whether the upper body is closed or opened,
In any case, the operation is free from complexity.
等の種々の著効を有す。It has various remarkable effects.
