Abstract
PURPOSE: To prevent the occurrence of casual accidents by inhibiting driving of at least one load when the plural loads which are normally not driven simultaneously are going to be driven at the same time with respect to the driving power stabilizing device used for the image-forming device of the scanning type copying machine.
CONSTITUTION: When the forward moving signal S6 is held set owing to the occurrence of trouble in a control circuit Q1 at the forward moving of an optical system or when it is held turned ON owing to the occurrence of trouble in a hammer driver Q2, a microswitch SW1 is operated to turn OFF a forward-moving clutch Cl1. Even when a trouble occurs in the backward moving, a switch SW2 is operated to turn OFF the backward moving clutch Cl2. However, when the signals S6, S7 act simultaneously, a normally closed contact K1-1 normally monitored by a monitor circuit a opens to cause the forward moving clutch Cl1 to go OFF and the backward moving clutch Cl2 to go ON, due to which the optical unit returns to the initial position.
