Abstract
The present invention provides a tape cassette used as a recording medium for the recording and/or reproducing apparatus, such as a tape recorder. The tape cassette includes a lid for protecting the tape during the time the tape cassette is not used and a lock lever for locking the lid in a closed state. According to the present invention, the abutting portion on the lock lever on which abuts the release pin of the aforementioned recording and/or reproducing apparatus which is adapted for releasing the lock of the lock lever, is inclined with respect to the moving direction of the release pin, so that, when the release pin undergoes positional deviation in a direction orthogonal to its moving direction, the lock lever may be at a predetermined position when the lock lever is released, so as to prevent the lock lever from contacting with the tape in the tape cassette due to the aforementioned positional deviation of the release pin to assure the running stability of the tape.
