PROBLEM TO BE SOLVED: To execute high speed film feeding necessary for fast forward or the like of a photographic film, low speed film feeding necessary for the scanning feeding of film images and film feeding from a film cartridge only by one reel motor. SOLUTION: Rotational driving force is transmitted from a reel motor 227 to a feeding reel 209 or a winding reel 204 through an oscillating gear mechanism 228 or 229. The reduction gear ratio of a gear string for transmitting driving force through the mechanism 228 is different from that of a gear string for transmitting driving force through the mechanism 229. Which gear mechanism is to be used is selected by cam plates 238, 239 or the like. Since either one of the two gear mechanisms 228, 229 is properly selected and used, the rotational speed and direction of the reel 209 can be changed over the speed changeable range of the motor 227 and the rotational speed of the reel 204 can also be changed. |
