A tape cartridge mounted to a tape printer includes a ribbon feeding core on which an ink ribbon is wound so as to be capable of being fed and a ribbon winding core that winds the ink ribbon fed from the ribbon feeding core. In the tape cartridge, the ribbon feeding core includes a core body that winds the ink ribbon and a shaft engaging part formed at an end portion of the core body and engaged with a feeding-side driving shaft of the tape printer. The shaft engaging part protrudes in an axial direction of the core body from an end surface of the core body and is formed in a crown shape in which a plurality of convex portions and a plurality of concave portions are alternately arranged side by side in a circumferential direction.

A disclosed media processing device includes a lid hingedly attached to the base movable relative to the base between a closed position and an open position, wherein a cavity is defined between the base and the lid; a platen roller to form a first nip with a printhead, wherein media having a backing is to travel through the first nip; a modular peeler configured to remove the backing from the media downstream from the first nip, the modular peeler including a peel roller to form a second nip with the platen roller, wherein the backing is to travel through the second nip after being removed from the media.

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 disclosed ribbon cartridge includes a first spool housing configured to receive a first spool; a second spool housing configured to receive a second spool; a first frame member extending between the first and second spools; and a second frame member extending between the first spool and the second spool; wherein a printhead assembly opening is defined and bounded by the first spool housing, the second spool housing, the first frame member, and the second frame member, wherein the first frame member defines a first channel adjacent to the printhead assembly opening, wherein the second frame member defines a second channel adjacent to the printhead assembly opening, and wherein the first channel and the second channel each comprise a drive surface, wherein the drive surface is configured to be engaged by a printhead assembly to drive the ribbon cartridge to an installed position within the media processing device.

There is provided a bobbin for a thermal transfer sheet or an image-receiving sheet which can reduce the number of parts and can have a smooth surface. The bobbin includes a cylindrical bobbin body 11. A gear 12 including a number of teeth 13 is formed in one end surface of the bobbin body 11. The teeth 13 of the gear 12 each have the shape of a trapezoid when viewed from the side. One lateral side 13b of the trapezoid extends in the axial direction of the bobbin body 11.

An ink ribbon includes a core and a mounting section. The core is configured to be wound with an ink ribbon tape. The mounting section is mounted with an identification information recording part in which identification information of the ink ribbon tape is recorded to be inputtable and outputtable. The mounting section includes at least one hole section which supports at least one end portion of the core to be rotatable. The mounting section covers at least a part of the core via the ink ribbon tape wound around the core in a state where the core is rotatable.

An example disclosed printer includes a base; a lid hingedly attached to the base movable between a closed position in which the lid is secured to the base, and an open position in which the lid is at least partially separated from the base; a cavity defined between the lid and the base, wherein the cavity is inaccessible when the lid is in the closed position and the cavity is accessible when the lid is in the open position; a ribbon positioning assembly disposed within the cavity that is pivotably attached to at least one of the lid or the base wherein the ribbon positioning assembly is configured to move between a printing position when the lid is in the closed position, and an accessible position when the lid is in the open position, wherein the ribbon positioning assembly comprises a ribbon tensioning mechanism.

A disclosed ribbon cartridge includes a first spool housing configured to receive a first spool; a second spool housing configured to receive a second spool; a first frame member extending between the first and second spools; and a second frame member extending between the first spool and the second spool; wherein a printhead assembly opening is defined and bounded by the first spool housing, the second spool housing, the first frame member, and the second frame member, wherein the first frame member defines a first channel adjacent to the printhead assembly opening, wherein the second frame member defines a second channel adjacent to the printhead assembly opening, and wherein the first channel and the second channel each comprise a drive surface, wherein the drive surface is configured to be engaged by a printhead assembly to drive the ribbon cartridge to an installed position within the media processing device.
