The driving mechanism comprises a slidable shaft provided on a rotary drum for movement in axial direction thereof, an arm member having one end secured to one end of the sliding shaft, a socket member having an intermediate portion rotatably supported at the other end of the arm member, a crank arm having one end secured to one end of the socket, the other end of the extension shaft being secured to the other end of the socket member and coupling member for snap coupling together the arm member and crank arm at a predetermined rotational position. Thus, the pushing member may be movable between the position where it faces with the core member and the position where it does not face the same.
