    • Provided is an image forming apparatus capable of detecting the ON/OFF state of each of two interlock switches connected in series to a power line, and detecting the opening/closure of each of two covers. The first and second interlock switches are set on/off according to the opening/closure of the first and second covers respectively. The first interlock switch is connected to a supply voltage when the first interlock switch is on, and is connected to a detection voltage being lower and on which the load does not operate when the first interlock switch is off. A control part detects the opening/closure of the first cover and the second cover based on a voltage on the power line between the first interlock switch and the second interlock switch and a voltage on the power line between the second interlock switch and the load.
    • 提供了能够检测与电力线串联连接的两个互锁开关中的每一个的ON / OFF状态并检测两个盖中的每一个的打开/关闭的图像形成装置。 第一和第二互锁开关分别根据第一和第二盖的打开/关闭而被设定为开/关。 当第一联锁开关打开时,第一互锁开关连接到电源电压,并且当第一互锁开关断开时,连接到检测电压较低并且负载不工作。 控制部分基于第一互锁开关和第二联锁开关之间的电力线上的电压以及第二互锁开关和负载之间的电力线上的电压来检测第一盖和第二盖的打开/关闭。
