ABSTRACT:
A lens-fitted photographic film unit has an optical viewfinder whose lens elements are held at their top side by a finder lens holding plate. The finder lens holding plate extends beyond the top side of the finder lens elements and has holes for receiving upper tips of axles for pivoting a shutter actuating lever, a frame counter dial, an arresting lever and a spring for urging the shutter actuating lever in a direction against a cocked position. The finder lens holding plates also has an arched wall which contacts a peripheral surface of a cam unit including a one-tooth gear so as to rotatably support the cam unit. The one-tooth gear is engaged with teeth formed around the periphery of the frame counter dial. The engagement between the one-tooth gear and the teeth of the frame counter dial is maintained constant by virtue of the hole and the arched wall of the finder lens holding plate.
