Abstract
PURPOSE: To eliminate time lag and prevent the malfunction that a movable mirror retreats to outside the taking optical path prior to determination of aperture by so constituting the camera that the retreat of the movable mirror to outside the taking optical path starts at the same instant when the aperture is automatically determined.
CONSTITUTION: When the output by the preset shutter speed and the preset film sensitivity and the output of a photo-cell 8 incident through an aperture 2 reach a balance state, a blocking lever 33 turns in a clockwise direction and the claw 33a at its end blocks the movement of an aperture-actuating member 32 and an operating pin 16, by which the aperture value is automatically determined. At the same time, the clockwise turning of the blocking lever 33 causes the engagement between its arm 33b and one end 34b of a mirror lever 34 to be released, then the mirror lever 34 turns in the arrow B direction around a shaft 34a, and a mirror 3 is retreated from the taking optical path region by the shaft part 35 integral with the mirror lever 34. In this way, time lag may be eliminated and the malfunction of the movable mirror may be prevented.
