Abstract
A ribbon transport mechanism includes an input gear that receives rotational power from a transport motor. An intermediate gear, which engages with the input gear, receives the rotational power from the transport motor via the input gear and transmits the rotational power to a first paying out rotor. When the cartridge is attached, a paying-out-side one-way clutch suppresses the input gear from rotating in a first input direction and the intermediate gear from rotating in a first intermediate direction and permits the input gear to rotate in a second input direction and the intermediate gear to rotate in a second intermediate direction. An elastic member applies force to the intermediate gear in the second intermediate direction to reserve a clearance between the input gear and the intermediate gear and next to a front end of the intermediate gear in the first intermediate direction.
