A tape cassette characterized by having a shaped groove. In the tape cassette described in Claim 1 of the Utility Model Registration Claim, when the front cover is closed, only the upper inclined surface of the mountain-shaped protrusion comes into contact with the upper inclined surface of the V-shaped groove, and a moment is applied in the direction of closing the lid. On the other hand, when the lid is opened , only the lower sloped surface of the mountain-shaped protrusion comes into contact with the lower sloped surface of the V-shaped groove, and a moment is applied in the lid opening direction.

Claims

[Scope of Claim for Utility Model Registration] A tape cassette main body, a rotary opening/closing front lid, a sliding member that presses against the front lid and applies an opening/closing moment, and this sliding member presses against the front lid. a resilient member, a mountain-shaped protrusion is provided on one side of the pressure contact portion between the front cover and the sliding member, and a plurality of V-shaped portions are provided on the other side.
A tape cassette characterized by having a shaped groove. In the tape cassette described in Claim 1 of the Utility Model Registration Claim, the mountain-like protrusion is formed on the inclined surface of the V-shaped groove so that a moment is applied in the closing direction when the front lid is closed and in the opening direction when the lid is opened. It is configured so that it comes into contact with the
