Abstract

PURPOSE:To let a person to be photographed know previously that flash photographing is performed by so constituting that when a state of flash photographing was selected, an indication with light emission is done toward the front of a camera previously. CONSTITUTION:When a main switch Si is closed, voltage of a power source E is raised with a boosting circuit C, capacitors C1, C2 and C3 are charged, and when charging of the capacitors C2 and C3 terminates, a neon lamp NE is lighted. When a shutter release button is pushed down, a switch S2 is closed, allowing a switching circuit S of a brightness detecting circuit B to be actuated. When the output is a low level, a Tr1 does not conduct. When the shutter release is further pushed down, a switch S4 is closed with charging of a capacitor C1, a trigger coil L is energized and a Xe lamp emits light slightly with charged energy of the capacitor C2, allowing a person to be photographed to foreknow flash photographing. When the release is further pushed down, S4 is opened and an S5 and an S3 are closed in order, thereby allowing the Xe lamp to be discharged by the main capacitor.
