Abstract

PURPOSE:To make construction simple and prevent the occurrence of toubles by making combination use of one piece of a synchronizing terminal for transmission of synchronizing information charging completion information, aperture information, etc. CONSTITUTION:A strobe is mounted and terminals S1, S1' and S2, S2' are connected. When a switch 10 is turned on after this, a light emission control circuit 1 starts charging, and a signal Cs goes to H. A light emission inhibition circuit 3 outputs a light emission inhibition signal to the circuit 1 and a charging completion signal transmitting circuit 4 grounds the terminal S1'. Upon completion of the charging, the signal Cs goes to L, and the circuit 3 releases the inhibition of light emission. The circuit 4 interrupts the grounding. The voltage signal Av1 from an aperture signal generating circuit 5 appears, and an aperture signal identifying circuit 7 outputs an aperture signal Av2. A changeover signal generating circuit 8 outputs a signal Ds, by which a light emitting diode 9 is lighted, and a shutter speed change- over signal S is outputted. Thereby, the construction is made simple and occurrence of troubles is prevented.
