Abstract
A photographic camera having a built-in generator connected with an electric shutter control circuit in which the generator is rotated by an operating member to produce electricity to be supplied to said electric shutter control circuit in response to a shutter release operation. A switch is interposed between the generator and the exposure control circuit, and the switch is not closed until the operating member is moved by a predetermined distance to rotate the generator for a time longer than the rising time of the output current of the generator so that only a stable current is supplied to the exposure control circuit from the generator.
