Abstract:
In a tape cassette housing having an opening through which magnetic tape contained in the housing can be engaged and withdrawn from the housing, for example, for the recording and/or reproducing of signals on the tape by means of a head assembly outside the cassette, and a pivoted lid for closing such opening; a latch mechanism is provided for locking the lid in its closed position to normally protect the tape, and such latch mechanism is released by an actuating element which is inserted into the cassette housing in the normal course of the positioning of the cassette in the holder therefor of the recording and/or reproducing apparatus. The latch mechanism includes a keeper on the lid disposed within the cassette housing adjacent an edge of the opening when the lid closes such opening, and a latching element slidable rectilinearly in a guide provided at the inside of a wall of the housing and having a latch nose at one end of the latching element engageable with the keeper under the urging of a spring. The housing wall and latch element have adjacent apertures which are normally offset relative to each other and which are brought into registry by the penetration of the actuating element through the wall aperture, whereby to displace the latching element against the force of the spring for relasing the latch nose from the keeper.
