Autofocus camera

Abstract

Abstract PURPOSE: To reduce consumption of a battery, by changing the light quantity of the light source according to use or disuse of strobe. CONSTITUTION: In the case of use of strobe, change-over switch 19 for strobe photography is switched to the strobe light emitting circuit 16 side when strobe switching button 7 is operated. At release, switch 20 is turned on, and light directing lamp 5 is driven through resistance 17 by power source 22 and lights brightly. At further release, autofocus circuit 21 and strobe light emitting circuit 16 operate to release the shutter. In case that a self-timer is used at the using time of strobe, light directing lamp 5 lights brightly also due to closing of switches 17 and 20. Meanwhile, when strobe is not used but the self-timer is used, switch 14 is closed, and light directing lamp 5 is driven through resistance 18 by power source 22 and lights darkly.
