ABSTRACT:
A film cartridge driving mechanism of a camera, comprises: a spool driving member, capable of engagement with a spool shaft of a cartridge loaded, for rotating the spool shaft; and a power transmitting member for transmitting a driving force of a motor to the spool driving member, the spool driving member having an engaging part capable of engagement with the spool shaft, a locating part for locating the engaging part in a predetermined position with respect to a camera body, a biasing member for effecting a bias so that the locating part engages with the camera body to thereby set the engaging part normally in the predetermined position, and a centering part, forced by the spool shaft of the cartridge as the film cartridge is loaded, for moving the locating part with resistance to the biasing and simultaneously centering the engaging part with respect to the spool shaft by shifting the engaging part in the radial direction thereof.
