Abstract
A tape cassette is provided with a slider serving as a reel lock releasing element and which is movable in the front-to-rear direction near the rear of the cassette, along a path defined by a guide. A guide groove is formed in the underside of the cassette in alignment with the guide for the slider. The slider has a downward projection extending into the guide groove through an elongated opening in the guide. The downward projection is abutted by a projection built into the playback unit, and which is received in the guide groove for guiding the cassette during its insertion into the playback unit or VTR. Therefore, insertion of the cassette causes the cassette guiding projection to displace the slider for releasing the tape reels.
