ABSTRACT:
In a camera including a shutter member, a spring urged striker member adapted to be moved from an initial position to a fully cocked position and then released to strike the shutter member to cause the shutter member to move momentarily away from the lens opening of the camera, a drive gear is provided for moving the striker member from an initial to a fully cocked position during only part of the movement of a manually operable film winder member during a film winding operation. The striker member includes a gear segment including a toothed portion provided with teeth meshable with gear teeth of a first portion of the drive gear and a dead motion portion free of gear teeth so that further movement of said drive gear will not move the striker member beyond the fully cocked position, the striker member being held in the fully cocked position by the abutment of the last tooth of the gear segment with the drive gear.
