A printer includes, a printing portion configured to print on a print medium, a ribbon supply shaft configured to hold an ink ribbon to be supplied to the printing portion, a ribbon roll up shaft configured to roll up the ink ribbon used in the printing portion, a partition member provided swingably, the partition member partitioning the ink ribbon and the print medium; and a ribbon supply shaft lock mechanism configured to regulate rotation of the ribbon supply shaft, wherein the ribbon supply shaft lock mechanism is switched between a lock state where the rotation of the ribbon supply shaft is regulated and a non-lock state where the rotation of the ribbon supply shaft is permitted in conjunction with swing actions of the partition member.

A tape drive comprises a spool support (30) for supporting a tape spool (32), wherein the spool support comprises a support surface (34) mounted to a tape drive base plate (36) such that the support surface (34) is fixed against rotation relative to the base plate (36), the support surface (34) being configured such that, in use, as tape is removed from or wound onto the spool (32), the spool (32) rotates relative to the spool support (30) such that the spool (32) rotates around the support surface (34).

An ink cassette comprises a supply bobbin, a winding bobbin, and an enclosure including a supply bobbin storage portion and a winding bobbin storage portion. In the supply bobbin storage portion and the winding bobbin storage portion, an opening is provided in one side surface of the enclosure, with an elastic piece provided within each of the openings, and a rotation restricting portion is provided on an inner side of another side surface of the enclosure. The supply bobbin and the winding bobbin has a rotation-restricted portion. The supply bobbin and the winding bobbin are biased by the elastic pieces toward the other side surface in which the rotation restricting portions are provided, and the rotation-restricted portions engage with the rotation restricting portions and restrict rotation of the supply bobbin and the winding bobbin.

A described example includes a ribbon cartridge having a first spool housing to receive a first spool. The ribbon cartridge further having a second spool housing to receive a second spool. The ribbon cartridge further having at least one frame member extending between the first spool housing and the second spool housing and a spool lock, wherein the spool lock is configured to engage at least one of the first spool or the second spool in response to the ribbon cartridge not being received within a ribbon positioning assembly.

The present invention embraces printers such as hand-held printers and mobile/portable printer. One exemplary embodiment includes “print as you glide” (PAYG) devices. Such printers may comprise a modular print engine that is removable from the printer and may allow a user to easily access and load the ribbon in the mobile print engine. The modular print engine may comprise a modular print head and an encoder that may determine the movement of the print head relative to a stationary media. When a printer is pressed against the media, the print head's burn line may be resting on the media. When the printer is stationary relative to the media, the encoder may not trigger the printing. Once PAYG is being slid or glided across the media, the encoder may start to rotate and then send a signal to a processor, causing the printer to start printing.

A printer includes a printing unit configured to print on the print medium, a ribbon shaft configured to hold the ink ribbon, a partition member provided swingably between a close position where gears that transmit drive force to the ribbon shaft mesh with each other and an open position where meshing between the gears is released, and a lock mechanism configured to hold the partition member with respect to the printing unit when the partition member is placed at the close position.

A tape cassette includes a tape, a transparent cover film, and an ink ribbon. The tape has a thickness in a thickness direction and a width in a width direction. The tape is configured of a plurality of laminated layers including: a transparent base layer; a background layer having a width smaller than the width of the tape in the width direction; and a release layer constituting one surface of the tape in the thickness direction. The transparent cover film is to be bonded to the tape. The ink ribbon contains ink to be transferred to one of the tape and the cover film.
