Zusammenfassung:	A film motor drive system includes a motor provided in a motor drive portion and a second motor provided in a long-film magazine portion. An electric circuit is provided so that the motor in the long-film magazine portion alone is energized when a camera's sprocket is made free to rotate by upward movement of a camera's rewind button during film loading or at the end of photo-taking operation. Thus, the forward and rearward leaders of the film may be taken up before and after the photo-taking operation. The motor drive system may further include forward counter means and/or reverse counter means connected with a switch inserted in the electric circuit.
