Abstract

PURPOSE: To make it possible to perform daylight synchronous photographing by providing means of generating a trigger signal in nearly a predetermined constant time before the shutter closing time.
CONSTITUTION: Depression of a shutter button causes a claw 2 to disengage and a sector ring 1 to be rotated rapidly by a spring 1c, by which shutter bladed are opened. This lets a switch S1 be closed by a projecting part 1b, thence a capacitor for counting of a control circuit for the quantity of emitted light starts charging. On the other hand, a claw 3 is released as well synchronously with the claw 2, by which the detention of a lever 4 is turned off. After the stoppage by part 5 of a mechanical governor is released, the lever 4 rotates to close a switch S2, by which a flash device is triggered to start emitting light. Following to this, the lever 4 contacts the pin 1d of the ring 1 upon lapse of the predetermined time after the closing of the switch S2, causing the shutter blades to be closed rapidly. Since the light emission may be started in the predetermined time before the shutter closing in this way, the daylight synchronous photographing may be done.
