A cassette case includes a bottom case and a top case. A tape is housed in the cassette case. A tape discharge portion discharges, from the cassette case, the tape that has been guided in the cassette case along a predetermined feed path. A first indicator portion indicates a type of the tape. A second indicator portion indicates a type of the tape, which is different from that indicated by the first indicator portion. An indicator member is a member independent from the top case and the bottom case, and is provided with the second indicator portion. An attachment portion is provided on the cassette case. The indicator member is removably attached to the attachment portion.

A tape cassette that includes a box-shaped cassette case whose outline being defined by a bottom wall, a top wall, and a side wall and including a plurality of corner portions, at least one tape contained within a tape containment area defined within the outline, a pair of cavities extending from the bottom wall and being provided between the tape containment area and the outline at opposite ends of a diagonal line connecting one of the corner portions to another of the corner portions, and a side face indicator portion provided in the side wall, indicating a type of the tape, and including a plurality of indicator portions disposed in a pattern in accordance with the type of the tape, each of the indicator portions being one of a switch hole and a surface portion.

A tape cartridge or the like which can be pulled out of a cartridge loading section while maintaining a loading posture is to be provided. A tape cartridge is configured to be able to be loaded in and unloaded from a tape printing device. The tape cartridge includes a tab portion which is gripped at least at the time of unloading. The tab portion is arranged at or near a position where pull-out resistance due to unloading is balanced within a plane intersecting with an unloading direction.

A housing case includes a tape roll housing section configured to house a tape roll of a wound tape to be fed to a tape printing device, a tape discharge side removal portion removably provided in a first wall section, the tape discharge side removal portion to be removed to form a tape discharge in the first wall section through which the tape fed from the tape roll is fed, and a cartridge housing section configured to house a ribbon cartridge having an ink ribbon, the ribbon cartridge to be mounted into the tape printing device and being configured to hold the tape fed from the tape roll.

A tape cassette includes a cassette case, a tape roll, an ink ribbon, an arm portion, a long hole, and a ribbon take-up spool. A first distance, which is a length of the long hole in a left-right direction, is larger than a second distance, which is a length from a right side surface of the cassette case to a right side end portion of the long hole. A center of gravity of the tape cassette is located in a specific area, which is an area whose both end positions in the left-right direction are the same as both left and right side end portions of the long hole, and which extends in a front-rear direction of the cassette case. The right side end portion of the long hole is located further to the right than a center of the ribbon take-up spool.
