ABSTRACT:
Disclosed herein is a shutter actuating mechanism for a photographic camera. The mechanism comprises a pair of spaced members adapted to be engaged by the thumb and forefinger of the camera user, and a resilient member positioned therebetween. A pinching or squeezing movement between the finger thumb and forefinger causes the spaced members to move toward each other, thereby producing a displacement of the resilient member. Such displacement of the resilient member produces a force which is used to actuate a shutter. Preferably, the spaced members, the resilient member and a plurality of coupling hinges comprise a one piece plastic structure having a constant transverse cross section, whereby the shutter actuating mechanism can be produced by conventional extrusion techniques.
