A roll film driving device is capable of accommodating different film cartridges housing reels of different coupling methods to a driving shaft and forwarding and reversing the reeled film by coupling the reel with the driving shaft. The driving shaft is provided with different coupling members respectively adapted to different reels of the film cartridges, wherein each coupling member is bound to the driving shaft in the rotating direction but is axially movable between a coupled position and a noncoupled position, and a coupling member matching the reel of the loaded cartridge is selected to make such movement.
