Abstract

PURPOSE: To make possible always correct flash photography by changing the secon time to the flash photography mode when the main capacitor of theflashihg device is charged to the specified voltage and letting the shutter be closed upon flash starting.
CONSTITUTION: When then main capacitor Cm of a flashing device F is carged up to an emittable voltage, the shutter second control circuit of an electronic circuit C is set to the flashing mode and the shutter second time is fixed at the second time for flashing. When flash starting is accomplished upon turning ON of the x contact, the second time control circuit is operated to have the shutter close signal outputted. thereby, the second time control is accomplished at the flash photography mode only when the main capacitor Cm or the like has been put in a charging complete state and correct flash photography is made possible. In addition, the shutter rear curtain is run after the flash starting is done and flash is emitted when the shutter is held fully open.
