Abstract

PURPOSE: To enable the shutter second time for flash photography to be surely set by displaying the shutter second time value for flash photography when set at the specified shutter second time and checking this.
CONSTITUTION: When a flash device is mounted to a camera and its power switch is turned ON, charging of a main capacitor for storing flash energy is completed, by which a light emitting diode 120 is flickered and a warning is given to the photographer so as to set the shutter second time for flash photography. Next, the photographer manually turns the shutter dial and when the shutter second time value is set between 1/60 second to 1/4 second in cooperation to this turning, a switch 121 goes ON, due to which current normally flows to a light emitting diode 120 which then keeps going on, thus indicating that the shutter second time for flash photography has been set.
