Abstract
PURPOSE: To make the stable photography possible not only by the wide-open photometry but also by the iris-out photometry by effecting the photometry through a photometric switch during the delayed operation of a mirror pop-up drive member which is operative to make the abrupt operations slow after completion of the iris- out operation.
CONSTITUTION: Through a release lever 1, which is released from its retention by the rocking motions of a retaining member 8 made coactive with a release button, an iris-out member 3, which is charged during the film winding operations, is turned so that a mirror drive member 2 and a sector gear 28 are slowly turned by a delay mechanism composed of a coactive anchor 33. As a result, a pin 22 is pushed through the member 3, a connecting lever 4, a pin 18, a stopping lever 5, a pushing portion 5b of the lever 5, a pin 19 and an auto hinge 6 so that a preset diaphragm stop is performed without any bound of the shutter blade. Then, the pin 16 of the member 2 turns off a switch s to store the photometric level through a mirror 12 in a memory so that the member 2 and the pin 13 are brought into abutment after a preset delay time, thus slowly popping up the mirror 12.
