Abstract
A shutter-plate operating means for a camera is arranged for sliding and pivotal movement within a shutter housing and is spring-biased out of a cocked position, said operating means and a shutter plate being provided with interengageable cam surfaces, such that upon sliding movement of the operating means into a cocked position the cam surfaces will co-operate to cause the operating means to pivot to allow it to pass beyond the cam surface of the shutter plate, and such that upon release of the operating means from its cocked position, interengagement of the cam surfaces will cause the shutter plate momentarily to open a shutter aperture. Preferably the shutter plate operating means comprises a single, integrally formed shutter plate operating element which is generally planar, is arranged for sliding movement within the housing and includes the cam surface for operating the shutter plate, said cam surface being mounted on a resilient integral extension of said shutter plate operating element.
