Abstract
PURPOSE: To prevent consumption of unnecessary power and miniaturize the cine camera, by electronically controlling the prohibition of power supply to the exposure control circuit and lighting of illumination for finder inside until shooting is actually done at the time of different shooting mode.
CONSTITUTION: By setting to a interval shooting mode of specified second time, an AND gate AND1 is opened by a decoder 12. When a shutter moves one stroke by pressing a release member 1 to close a switch SW1, AND gates AND8, 9 are opened. When a switch SW2 is closed by a second stroke, FF1 is set, and a counter 10 starts counting accorcing to the setting, then transistors Tr1, Tr2 are made to conduct by the high level output of the counter 10 to supply power to an exposure control circuit 4. At the same time, a lamp 6 of a finder lights up. The operation is similar in other modes than ordinary picture taking. Only in the period of actual shooting, power supply to the exposure control circuit and lamp for finder is electronically controlled, so that consumption of unnecessary power may be prevented.
