Abstract

PURPOSE:To surely protect a circuit in a unit and to unnecessitate troubles and a warming-up time by impressing a power source voltage on the unit when a door is closed and stopping impressing the power source voltage on the unit when the door is opened. CONSTITUTION:When a right cover is closed, a control circuit 120 judges that the right cover is closed because a cover switch 133 is turned off and outputs a door closing signal from an output port 126 to a protection circuit 35 so as to output the power source voltage. When the right cover is opened, the control circuit 120 judges that the right cover is opened because the cover switch 133 is turned on and outputs a door opening signal from the output port 126 to the protection circuit 135 so as not to output the power source voltage. Thus, the circuit in the unit can be surely protected at the time of attaching and detaching the unit and the troubles and the warming-up time can be unnecessitated.
