To perform the plural kinds of operation control of a flashing device by using the same light receiving circuit.

By providing a photosensitive element 9 receiving light, a distribution circuit for plurally and simultaneously distributing the output from the photosensitive element and a photometric circuit having a circuit for processing each distributed output, the plural kinds of processing operation is performed by one photosensitive element. The distribution circuit is constituted of a circuit having current mirror constitution consisting of plural transistors 30, 31, 32 and 33, 34. Current flown to in the photosensitive element is fed from the respective transistors of the current mirror circuit connected to the photosensitive element, and the current is supplied to each circuit.
