Claims (1)

[Scope of utility model registration request] A part of the winding loop of the tape wound between a pair of tape reels disposed inside the cassette body is led out from one side plate of the cassette body, and the lead-out portion of the tape is covered. A lid body is attached to the cassette body so as to be openable and closable, and the lid body is locked to the cassette body by the lid lock claw &,E which is elastically biased by the elastic member when the lid body is closed. The lid of the tape cassette is opened, and includes a cassette holder portion on which the cassette is placed and held, and a lid lock release type provided in the holder portion that engages with the lock pawl when the cassette is placed. , a spring member that resiliently supports the lock release mold with a resilient force greater than the resilient force of the resilient member; and a spring member that is provided in the holder portion and which connects the actual lock pawl and the lock release mold when the cassette is placed. A tape cassette lid opening mechanism includes a lid raising member that opens the lid body after the lid is engaged.
