A film transfer apparatus includes a mechanism which is adapted to prevent a reverse rotation of a take-up reel (8) for a tape. The mechanism is formed of a check claw (29) and reverse rotation preventing teeth (30). The check claw and one of the teeth are engaged with each other firmly and reliably. When the check claw should be broken or deformed to cause the function thereof to become incomplete, only the member provided with the check claw needs to be renewed easily by a simple operation. A check pin (23) inserted from the outer side of a cartridge unit (2) into a cylindrical retainer shaft (20) on which the take-up reel is rotatably mounted is combined in one body rotationally with the take-up reel. The check pin is engaged in a reverse rotation preventing manner in a tightly winding direction with respect to the cartridge unit.
