A cassette includes: a tape roll rotatable about an axis extending in a first direction; a tape conveying passage; and first and second guides positioned at the tape conveying passage. The tape roll is a roll of a tape. The tape is conveyed in a second direction perpendicular to the first direction along the tape conveying passage. The first guide and the second guide are configured to guide widthwise edges of the tape in the first direction. The first guide has a first end surface and the second guide has a second end surface facing the first end surface in the first direction. The first end surface and the second end surface provide a distance therebetween in the first direction smaller than a widthwise length of the tape in the first direction.

An ink ribbon feeding mechanism includes a cartridge mounting section, a first paying out rotor which is inserted into a first paying out core when a cartridge is being mounted in the cartridge mounting section, and a plurality of rotor side engaging portions which are provided on the first paying out rotor and which engage with a plurality of core side engaging portions when the first paying out rotor rotates. The rotor side engaging portion has an butting portion. When the cartridge is being mounted in the cartridge mounting section, the core side engaging portion butts against the butting portion, one or the other of the first paying out core and the first paying out rotor rotates, the rotor side engaging portion is inserted into the core side insertion recessed portion. A plurality of the butting portions are provided in positions different from each other in a cartridge mounting direction.

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 tape cassette having a box-like case having first through sixth outer walls. The first and second outer walls extend in parallel and arranged in a first direction perpendicular to the first and second outer walls, the third and fourth outer walls extend in parallel and arranged in a second direction perpendicular to the third and fourth outer walls, the fifth and sixth outer walls extend in parallel and arranged in a third direction perpendicular to the fifth and sixth outer walls, and the first, second and third directions are perpendicular to each other. A discharging port is provided on the fourth outer wall, and a substrate having a storage storing electronically-retrievable information regarding the tape cassette. The substrate is provided to the third outer wall, and at least a part of the substrate overlaps at least a part of the discharge port in the second direction.
