ABSTRACT:
A camera which includes film transport means for moving a strip of film past a lens and shutter assembly in a stepwise, frame by frame sequence, with the film being maintained stationary when the shutter is in the open position. A toothed driven gear is in operative engagement with a film driven reel. A mutilated drive gear having a toothed portion with an end gear tooth and a smooth peripheral portion is rotated in time relationship with the opening and closing of the shutter. The driven gear contains a space between adjacent gear teeth (as by removing one gear tooth) whereby the end tooth of the drive gear is received in said space to facilitate the smooth "meshing" of the drive gear with the driven gear. The drive gear carries an arcuate cam segment and the driven gear carries an annular cam with an arcuate recess in the outer face thereof, whereby the arcuate cam segment is received in said recess when the shutter is in the open position, and the driven gear and the film driven reel are thereby maintained immobile.
