Claims

[Scope of utility model registration request]

Tape wound on a pair of tape reels is stretched along the front of the tape cassette, and an opening/closing lid that covers the front side of the tape along the front can be rotated to open and close via a rotating shaft parallel to the tape. In the tape cassette that is attached to the cassette case, a coil spring that biases the opening/closing lid to turn to the closed position is inserted through the rotating shaft, one end of this coil spring is fixed to the opening/closing lid side, and the other end is fixed to the opening/closing lid side. The end is a free end and is configured to come into contact with the inner surface of the cassette housing and slide on the inner surface as the opening/closing lid rotates to open and close, and the coil on the inner side surface of the cassette housing A tape cassette characterized in that an inclined surface is formed on the sliding trajectory of the free end of the spring or on an extension line thereof, on which the free end of the coil spring rides as the opening/closing lid is opened.
