Abstract
In a single lens reflex camera including a film transporting device capable of selectively effecting a wind-up mode in which a roll film wound on a first spool is taken up by a second spool after it has passed the focal plane of a phototaking lens and a rewind mode in which the film wound on the second spool is taken up by the first spool, and a mirror box for holding a reflecting mirror disposed across the light beam from the phototaking lens imaged on the focal plane and reflecting the light beam in a plane substantially orthogonal to the direction of transport of the film for pivotal movement about an axis passing through one end thereof for retraction from the light beam, the transporting device comprises drive means for selectively rotating the first and second spools in response to selection of said modes. The drive means includes a drive shaft disposed on a side opposed to the first spool with respect to the mirror box, belt means for transmitting the rotation of the drive shaft to the first spool, and means for guiding the belt means substantially in parallelism to the direction of transport of the film near the pivot of the reflecting mirror outside the mirror box.
