Abstract

PURPOSE:To make short charging time by applying preliminary charging at the same time as input of a power supply switch or the like of a device or a machine in the stroboscope circuit of a photography device mounted on an electric machine or a device. CONSTITUTION:When a power switch is input, the power supply is applied to the main circuit 39 of an electric machine or a device. In this main circuit 39, an electric circuit for controlling a camera is contained, and at the same time as the power supply is input, the power supply is applied to the transformer 3 of a stroboscope flasher circuit, and through the rectified secondary voltage the condenser 8 connected to a discharge tube 37 is charged. This charging voltage repeats charge and discharge through a discharge resistance 20 and comes to a specified preliminary charging voltage. Then, it is set to stroboscope and becomes dischargeable voltage, and performs discharging by flashing a signal in succession. Thus, the charging time can be made short by preliminary charging.
