Abstract

PURPOSE:To improve safety degree with a simple device, providing a switch turned on and off by opening and closing the side plate of the casing of an apparatus to detect the half-opened state of the plate, and controlling image forming operation. CONSTITUTION:A drum and a main motor for rotating this are arranged on the side of door 101, sheet conveying belt 19, fixing roller 20, or the like are located on main body side 105, and belt 19 and roller 20 are engaged with the main motor with gear 113. For example, after dealing with jam, door 101 is closed, and when half-opened, it is detected by half-opened door switch 100. Namely, when door 101 is not perfectly closed, door switch 104 and said switch 100 close, resulting in turning on transistor 102 through diode 106 by electric power supply V, and grounding LED 103 to light a lamp. At the same time, a stop signal is applied to CPU to disable copy start. When door 101 is perfectly closed, switch 100 is opened, enabling copying.
