Camera with apparatus for maintaining film flat during photographing operation |
摘要 |
A camera having a photographing mask, a cassette chamber on one side of the photographing mask and a film winding spool on the other side includes: a motor for rotating the winding spool in a film winding direction; a spring disposed between the cassette chamber and the photographing mask, the spring having a first spring unit for pushing a film cassette, toward an inner wall of the cassette chamber to thereby position the cassette, and a second spring unit for pushing the film, drawn from the film cassette, toward the photographing mask to thereby apply a predetermined load against movement of the film; and a device for applying to the film a tensile force which is smaller than the predetermined load on the film winding side. Thus, it is possible to dispense with an independent pressure plate.
