The figure is a plan view of a conventional VHS tape cassette. FIG. 3 is a partial cross-sectional view taken along line AA in FIG. 2, illustrating the opening and closing states of the lid member. FIG. 4 is a partial sectional view similar to FIG. 1, showing the positional relationship between the side surface of the longitudinal end edge of the lid member of a conventional magnetic tape cassette and the stepped surface of the upper half member. FIG. 5 is a partial perspective view of a conventional lid member. Figure 6 shows the conventional VH used for vibration testing.
FIG. 3 is a partial cross-sectional view of the S tape cassette. FIG. 7 is a partial sectional view of another conventional VHS tape cassette that was subjected to a vibration test. The names of the main parts in the figure are as follows. 2: Upper half member, 4: Lid member, 6: Longitudinal end portion, 8: Stepped portion, 10: Side surface, 12: Stepped surface, 14: Space portion widening toward the end.

Claims

[Claims for Utility Model Registration] A reel member wound with a magnetic tape is rotatably stored between the upper and lower half members, a lid member for taking out the magnetic tape is provided on the front surface so as to be openable and closable, A side surface along the longitudinal direction of the portion of the lid member overlying the upper surface of the upper half member is loosely received in a stepped portion formed on the corresponding portion of the upper half member when the lid member is closed; A magnetic tape cassette in which the side surface of the lid member and the stepped surface opposite to the side surface of the stepped portion are complementary sloped surfaces, wherein the side surface of the lid member or the stepped surface of the upper half member A magnetic tape cassette characterized in that the mutual inclination angles of the magnetic tape cassettes are changed so that the space formed between the side surfaces and the stepped surfaces becomes wider as it goes inward.
