PURPOSE:To reduce the number of component parts to lower a cost by a method wherein the opening/closing states of two covers are detected by one sensor with respect to a cover opening/closing detection device for detecting the opening/closing states of the covers as a fail-safe function. CONSTITUTION:A mechanism comprises a rotating holder 21 rotated and separated from a cover 17 when a cover 18 is opened and a rotating switch 22 mounted on the rotating holder 21 in proximity to the cover 17 and turned ON/OFF when the cover 17 is separated for detecting the opening of the cover 17 or 18. Based on the detection information of the rotating switch 22, the opening/ closing states of the covers 17, 18 are detected. |
