Abstract
An electric source circuit for a camera in which the voltage of a power source is automatically applied to the exposure control and display circuit of a camera when the electronic flash is fully charged. A first switch circuit is operatively coupled between a power source and the exposure control and display circuit. A photometric switch for controlling the conduction and non-conduction of the first switching circuit is coupled in parallel with the second switching circuit. The second switching circuit is coupled to detect when the electronic flash mounted on the camera is fully charged. A third switching circuit can be provided for activating an indicating device such as an LED or piezoelectric transducer.
