Abstract

Abstract A camera or other photographic apparatus having a shutter mechanism and using flash devices is provided with a mechanism for operating the shutter and firing the flash device in synchronism. The mechanism stores energy in response to depression of the camera body release, and then suddenly releases the stored energy through a synchronizing member causing the member to move in an operative path to actuate the flash device and the shutter mechanism.
