Abstract

A camera shutter driving mechanism includes a film-driven ratchet mechanism rotated by a film moving through a film passage in a camera, and a shutter release sensing mechanism located adjacent to and rotated by the film-driven ratchet mechanism to convert an axial pressure applied on a shutter release button into a rotary force that is acted on a link via a pull arm of the shutter release sensing mechanism, so that the link is moved horizontally to cause pivotal turning of a shutter blade from a closed position into an open position to admit external light into the camera.
