ABSTRACT:
A simplified miniature camera features a spring-actuated shutter-striking slider member having a film-engaging finger integral therewith for engaging a film during film advance to move the striker member to an energized position. The slider member energizing spring is disposed to provide not only translational urging to the slider member, but also rotational urging to provide such film engagement. The film engaging member, as well as an arresting pawl configured to arresting engage the takeup spool gearing drive are all integral in a one-piece slider member slidably mounted to a post in the camera body. Exposure is initiated by operator actuation of a rotatable control member rotating the sliding member to disengage the film-engaging finger from its captured state in a film perforation, thereby releasing the slide to strike an impulse shutter. Subsequent rotation of the slider member of the slider energizing spring not only rotates the slider and the film-engaging finger into engagement with a film perforation, but also returns the shutter control system to its dormant state without the necessity for an additional return spring. In one embodiment, a pair of sear portions are formed, one on the camera body, and the other integral with the slider member, and may form either an auxiliary cocking latch for testing the camera with no film in place, or in the alternative, as the normal shutter release latch.
