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).

A tape printing apparatus including three holding protrusions that are provided on a mounting portion cover and that hold a cartridge mounted in a cartridge mounting portion, a displacement member that, when the cartridge is mounted in the cartridge mounting portion, is displaced from a protruded position to a lower-side position by having the cartridge abut against a cartridge abutment portion, and an elastic member that applies force to the displacement member towards an opposite direction to a mounting direction. In the tape printing apparatus, when viewed from the mounting direction, the cartridge abutment portion is provided inside a virtual holding triangle having holding distal end portions that are distal end portions of the three holding protrusions as apexes.

A thermal-transfer printer, including a first case, a second case, an ink ribbon supporting member, a cover, and a head holder, is provided. The first case has a first opening on an upper side thereof. The second case is located on the upper side of the first case and attached movably to the first case to open and close the first opening. The second case includes a second opening on an upper side thereof and a third opening on a lower side thereof. The ink ribbon supporting member is attached to one of the first case and the second case. The cover is attached movably to the second case to open and close the second opening. The head holder is attached to the inner face of the cover and holds a printing head.

The disclosure discloses an adhesive tape cartridge including an adhesive tape roll. The adhesive tape roll winds an adhesive tape around a predetermined axis in a housing. The adhesive tape includes a base layer, and a first particle-containing adhesive layer. The first particle-containing adhesive layer is disposed on first side of the base layer in a thickness direction and comprises an adhesive to which particles having an average particle diameter of 10 μm or more are added. On condition that the first particle-containing adhesive layer is virtually divided into two equal parts as a first region on the first side in the thickness direction and an second region on an second side in the thickness direction, a volume proportion of the particles to the adhesive in the second region is larger than a volume proportion of the particles to the adhesive in the first region.

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 cartridge to be installed in a tape printing device includes: a cartridge case having a cartridge-side tape ejection port; a tape path that feeds a printing tape toward the cartridge-side tape ejection port; a platen roller that applies a feeding force to the printing tape; and an electrode part. When seen from a front side in an installation direction of the cartridge, a feeding angle that is an angle formed by a feeding direction of the printing tape at a portion at which the feeding force is applied to the printing tape by the platen roller when the printing tape is fed with respect to a direction in which the electrode part receives a force from a contact terminal part is less than 45°.
