Abstract

PURPOSE: To let only the electric shutter circuits be operated even when switches go out of order and automatic exposure photographing to be made by connecting all the electric circuits of attached functions to the lines for supplying operating voltage via normally open switches.
CONSTITUTION: An operating voltage supply line E1 is connected to the positive pole of a power source E and an operating voltage supply line E2 to its negative pole. A release switch SW1, a shutter mechanism starting capacitor C5 and others are connected between these. Here, a common line E3 for electric shutter is provided to the line E2 via switching transistor Q3 and all the elctric circuits of attached functions such as fixed exposure second time setting circuit SW5, R13 thru R15, Q7, etc., exposure multiplication conversion circuit C2, SW4, etc., parity check circuit As, R25, R26, etc., electric self-timer circuit SW3, C3, R27, etc., are respectively connected between said common line and the line E1 by way of normally open switches SW3 thru SW5. The above enable only the electric shutter circuits to be operated even if the switches or the electric circuits of the attached functions go out of order, thus enabling at least sutomatic exposure photographing to be performed
