Abstract
A camera film wind-up apparatus for winding up a film wound around a cartridge spool, the film being housed in a cartridge having the cartridge spool, comprises a first driving apparatus for rotatably driving the cartridge spool, a wind-up spool around which a film extended from the cartridge is wound, a second driving apparatus for rotatably driving the wind-up spool, and a control apparatus. The control apparatus controls the first driving apparatus so as to control the amount of rotation of the cartridge spool on the basis of the amount of the rotation of the wind-up spool during the winding-up of the film, thereby preventing the film from being tightly wound around the cartridge spool.
