Abstract

PURPOSE: To make possible checking of shutter release operation by providing a mechanism of releasing the inhibition of release operation when no film is loaded in the camera which makes possible release operation when the film is wound.
CONSTITUTION: In case no film is loaded, there is no film between a friction roller 2 and pressure roller (not illustrated) and therefore a film detecting member 11 has no forcing forward by the film, hence it retreats to the cover 1a side, along with which a limiting member 12 displaces backward by being pulled by a spring to push an inhibiting member 10 and disengage from a winding detention lever 6, thereby holding the same in the position of not hampering the release operation of a release button 9. Hence, the button 9 is capable of performing release operation irrespective of the film winding mechanism. When the film is loaded, the member 11 is pushed forward, causing the member 10 to engage with the inhibiting member operating pin 6b. Thus, the release operation of the button 9 is inhibited unless a winding lever 8 is operated.
