PURPOSE:To prevent respective parts and a film from flawing owing to abrasion powder and shavings by making the speed of coupling operation from a reel driving shaft to a reel slower than that of coupling releasing operation. CONSTITUTION:A solenoid 32 is turned on to disengage a stopper 35 from the lower support piece 25a of a rocking frame 25, which is placed in a free rocking state. When the rocking frame 25 is freed, the cylindrical shaft body 42 of a reel driving shaft 4 is extruded from a base shaft 41 at a low speed while rocking the rocking frame 25 by being energized by springs 30 on both sides of it and through the operation of a damper 72 to move the reel driving shaft 42 to the foremost position at a low speed through a spring 28. Simultaneously with the slow forward movement, they are driven in the opposite direction of the film feeding direction at a low speed through a motor and pressed slowly against a cartridge while rotating at a low speed.
