PURPOSE:To form a smooth photographing operation system by continuing or resetting photographing operation according to the charging state of the main capacitor of a strobe circuit part. CONSTITUTION:When the main capacitor of a strobe device 10 is charged to a low voltage value, a comparator 18 outputs an H signal, so a NAND circuit 19 outputs an L signal after a delay means 13 outputs a delay signal (d). When the charging voltage of the main capacitor is high, on the other hand, the comparator outputs an L signal, so the circuit 19 outputs an H signal. The output signal of the circuit 19 is supplied to a photography control means 6 and a NOR circuit 20. Therefore, when the main capacitor is charged incompletely and the circuit 19 outputs the L signal, a means 6 is inhibited from operating to generate a photographing operation signal (c). Further, the H signal outputted within the delay time between the signals (d) and (e) is supplied to a self-timer start circuit 4, which is then reset. When the main capacitor is charged to a high voltage, on the other hand, the means 13 does not operate and neither of the circuit 4 and means 6 is reset. |
