MIRROR, DOUSER AND SHUTTER OPERATING DEVICE OF LENS SHUTTER TYPE SINGLE-LENS REFLEX CAMERA

摘要

PURPOSE:To operate a mirror and a douser stably in association with a main operation part such as a shutter setting lever by providing the main operation part to a flank of a camera, and providing a gear mechanism part for film winding and shutter setting to the bottom surface. CONSTITUTION:When a shutter is set, a shutter setting shaft 2 is rotated to rotate a cam member 8 through gears 4, 5, and 6, turning an actuation lever 9. The mirror and the douser are set on an optical axis through a shutter driving lever 11 and an interlocking lever 13 by the rotation of the actuation lever 9. When a shutter button is pressed in said state, the shutter driving lever 11 moves as shown by an arrow to rotate the actuation lever 9 through a pin 12, and the interlocking lever 13 moves through a pin 14. Consequently, the mirror starts rotating and the douser rotates a little bit later to be put off the optical axis.
