Abstract

PURPOSE:To obtain the strobe device which is capable of knowing the degree of comsumption of batteries as well in addition to the remaining time up to light- emittable voltage by detecting the time contributing to the specified range of charging of a main capacitor and displaying the time required till the completion of charging. CONSTITUTION:When the main capacitor C1 of the strobe device is charged by an electric power source 1, the voltage corresponding to charging voltage is generated across the resistance R2. This causes an exclusive-OR gate to generate a high level output only when the charging voltage of the capacitor C1 is in the specified voltage range and this output lets clock signals be generated from a clock circuit 5. The signals are then counted by a counter 6. According to the count value of the counter 6 of this specified voltage range, the remaining time necessary for the capacitor C1 to complete charging is displayed by corresponding light emitting diodes 24-28 by way of a decoder 12 or the like. On the other hand, it is also possible to perform the decision of the rate of consumption of batteries according to the magnitude of the remaining time by this display.
