PROBLEM TO BE SOLVED: To provide the function of an interlock switch irrespective of the order of opening or closing the plurality of doors of an image forming device, without decreasing the operating accuracy of switches. SOLUTION: When a front door is closed, a presser member 121 pushes links 7a, 7b and release levers 6a, 6b, and when a right door is closed a presser member 107 pushes the right lever 6b to push an entire lever device 5 toward an interlock switch device 4 side, with the left lever 6a pushing an actuator 2 to turn a switch 1 on. When the front door is open and the right door is closed, the presser member 107 is pushed by the right lever 6b and a spring 9 pushes the left lever 6a back to turn the switch 1 off. When the front door is closed and the right door is open, the right lever 6b is not pushed and, with the left lever 6a and the right lever 6b held separated, the entire lever device 5 is separated from the interlock switch device 4 by the spring 9 to turn the switch 1 off. |
