Claims

[Scope of utility model registration request]

A housing that is assembled by combining an upper half and a lower half and stores a tape therein, an opening/closing lid that covers the tape forming a tape path on the front side of the housing when the lid is closed, and closing the opening/closing lid. A tape cassette comprising a mechanism for locking in the lid state includes a locking mechanism that engages the engaged portion of the closed lid to limit movement of the lid in the opening direction. In addition to a lock release action part that causes the lock release means of the recording and/or reproducing device to which the coupling part and the tape cassette are installed to release the engagement of the holding part with the engaged part; The locking member is configured to have an integrally deformable elastic arm portion that elastically deforms and urges the engaging portion in a direction to engage the engaged portion, and the elastic arm portion allows the above-mentioned A tape cassette configured to regulate the position of the locking member with respect to the upper half or the lower half when assembling the tape cassette to combine the half and the lower half.
