Abstract
PURPOSE: To prevent such malfunction that power supply is cut off prior to ending of exposure owing to the effect of noise, etc. by releasing the self-holding of power supply in cooperation to the operation of an exposure defining member.
CONSTITUTION: By the first stage operation of a release button, a switch S15 is turned ON to put second time control circuit 1 thru 7 in an operation state. By the second stage operation, charging of a capacitor 2 is accomplished and at the same times S16 goes ON and Trs 10, 11 go ON and further TR 12 goes on, whereby power supply to the control circuits is accomplished. When correct exposure is reached, current supply to an electromagnet 7 is cut off and shutter is closed. At this time, a power source switch 17 is turned OFF in cooperation to the operation of the shutter closing member, whereby the power supply to the circuits is cut off.
