Abstract

PURPOSE:To prevent malfunction due to variations in power voltage during motor driving by supplying a constant voltage to a motor driving control circuit. CONSTITUTION:In a camera motor driving device connected to a camera body 3 via contacts K1-K4, the depression of a release button of the device makes a connection between an Sa and an Sb as the 1st stage, and between the Sb and an Sc as the 2nd stage. The 1st-stage depression turns on a transistor TR5 and through the operation of a Zener diode ZD, a constant-voltage circuit C1 supplies a constant voltage to an FFC2. The 2nd-stage depression inverts an output L3 to a high level and an unshown mechanism completes photographing operation. When the button is released, the output L3 goes down to a low level and a motor driving circuit operates to advance a film until a switch SW is opened. The operate is stabilized because the voltage is made constant and the FF absorbs chattering.
