FIG. 2 is an enlarged plan view showing the lower half of the tape cassette and the tape reel with some parts omitted;
FIG. 3 is an enlarged perspective view of the main part showing the vicinity of the tape guide, where A shows both a partially pulled out state and a non-loading state of the magnetic tape, and B shows the lower edge of the magnetic tape. This is to explain the transition from the state in which the tape cassette is in contact with the tapered surface of the rib to the state in which the lower edge is in contact with the support surface. 5 and 6 show a second embodiment of the tape cassette of the present invention, FIG. 5 is an enlarged plan view with some parts omitted, FIG. 6 is an enlarged perspective view of the main part, and FIG. 7 is an enlarged perspective view of the main part.

Claims

[Scope of Claim for Utility Model Registration] After opening the lid rotatably attached to the tape cassette housing, the tape is stored in the tape cassette with both ends wound around the tape reel. In a tape cassette in which a part of the magnetic tape is pulled out from the tape cassette, a support part is provided inside the tape cassette to support the lower edge of the magnetic tape in a non-loading state where part of the magnetic tape is not pulled out. A tape cassette characterized in that it is formed near a tape guide.
