A bidirectional ribbon supply system for a printer includes: a shaft supported by a frame of the printer, the shaft to rotate about an axis; a pulley affixed to the shaft; and a bias member coupled between the frame and the pulley to apply a force to the pulley in either of a first or second direction responsive to rotation of the pulley in the other of the first or second direction, wherein rotation of a spindle supported on the shaft in the first direction dispenses inside-coated ribbon toward a printhead, and rotation of the spindle in the second direction dispenses outside-coated ribbon toward the printhead.

A ribbon reeling mechanism includes: a gear supporting member that supports a clutch gear rotatably and is configured to move between a mesh position at which the clutch gear supported by the gear supporting member is in mesh with a first reeling-side gear and a non-mesh position at which the clutch gear supported by the gear supporting member is not in mesh with the first reeling-side gear; a clutch impeding spring that causes a clutch impeding force of impeding movement from the mesh position to the non-mesh position to act on the gear supporting member when a feed motor starts rotating in the second rotation direction; a drive member engaged with the gear supporting member; and a clutch drive mechanism that causes the gear supporting member to move to the non-mesh position against the clutch impeding force when the feed motor rotates in the second rotation direction.

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.

The present application provides a torque limiter which includes a first torque limiting module for limiting a first torque with regard to a rotating direction and a second torque limiting module for limiting a second torque with regard to a counter direction of the rotating direction.
