Abstract
A camera system comprising an operation means for operating a film feeding part of a film cartridge. The operating means winds the film by feeding it out from the film cartridge, or it rewinds the film into the film cartridge. The camera system also has a drive force generating means for generating a drive force. The drive force is transmitted by both a first drive force transmitting means and a second drive force transmitting means. The first drive force transmitting means causes the operation means to drive the film in a winding direction. The second drive force transmitting means causes the film to be driven in the rewinding direction, where both drive forces are applied to the operation means.
