<p>PURPOSE:To automate strobe photography in an atmosphere of low illuminance by turning on a strobe power source with a low-illuminance warning signal, etc., from a camera side, resetting warning on the completion of charging, and setting a camera to a strobe synchronizing speed. CONSTITUTION:In an atmosphere of low illuminance, a transistor TR3 turns on and a shutter locking circuit 3 operates to turn on a warning lamp W. Consequently, a TR1 turns on and the DC-DC converter circuit 4 of a strobe 2 operates to charge a main capacitor C1. When a pilot lamp Ne turns on in response to the completion of the charging, a TR2 turns on and the TR3 turns off to release the locking of the locking circuit 3, turning off the warning lamp W. Further, a shutter control circuit 5 sets a shutter speed to a strobe synchronizing speed and a light emitting diode D4 turns on to display the completion of the charging on a camera side.</p> |
