ABSTRACT:
A camera includes a camera body having a photographing mask, a cassette chamber on one side of the photographing mask and a film winding spool on the other side. A motor rotates the winding spool in a film winding direction and a spring pushes the film toward the photographing mask to thereby apply a predetermined load against movement of the film. A roller applies to the film a tensile force which is smaller than the predetermined load on the film winding side to maintain the film flat at the photographing mask.
