BACKGROUND

The present disclosure relates to a tape cassette that is removably installed in a tape printer.

A tape cassette has been known that, when installed in a housing portion of a tape printer, selectively presses down a plurality of detecting switches provided on the cassette housing portion to cause the tape printer to detect the type of a tape stored inside a cassette case (a tape width, a print mode, etc.) More specifically, a cassette detection portion is provided on a section of the bottom surface of the tape cassette, where through-holes are formed in a pattern corresponding to the type of the tape. When the tape cassette is installed in the cassette housing portion, the plurality of detecting switches, which are constantly urged in an upward direction, are selectively pressed in accordance with the pattern of the through-holes formed in the cassette detection portion. The tape printer detects the type of tape in the tape cassette installed in the cassette housing portion based on a combination of the pressed and non-pressed switches among the plurality of detecting switches.

SUMMARY

The pattern of through-holes formed in the cassette detection portion is basically only designed to allow the tape printer to detect the type of the tape. Accordingly, different patterns are allocated randomly in accordance with the type of the tape. In other words, the patterns of through-holes are not formed in a pattern in accordance with rules to allow them to be identified from the outward appearance. Therefore, it is difficult for a person to visually identify the type of the tape. For that reason, for example, in a tape cassette manufacturing process, it may be difficult for a worker to visually identify the type of the tape that should be mounted inside the cassette case from the external appearance of the tape cassette.

An object of the present invention is to provide a tape cassette that allows a type of a tape to be identified by visually checking an external appearance of the tape cassette.

According to the present invention, a tape cassette includes a housing having a front wall and a tape feed exit located on the front wall, a tape at least partially included within the housing and configured to be fed along a tape feed path extending to the tape feed exit, and tape type indicator apertures formed on the front wall of the housing. A combination of the tape type indicator apertures forms a pattern corresponding to a type of the tape at least partially included within the housing. The tape type indicator apertures include a first tape type indicator aperture and a second tape type indicator aperture, and the tape type indicator apertures are positioned such that the first tape type indicator aperture is not aligned with the second tape type indicator aperture in a direction orthogonal to the tape feed path and parallel to the front wall. Other features are described in further detail below.
