<p>A tape cassette comprises a housing and a pair of reels mounted for rotation in the housing. A recording tape (T) is wound on the reels and extends therebetween for transport from one of the reels to the other. The housing is formed with an opening through which a transducer can gain access to the recording tape (T) to record or reproduce signals on or from the recording tape (T). Front (28) and back (32) lids are connected to the housing and are movable between a closed position wherein the front (28) and back (32) lids block the opening and form a channel capable of enclosing the recording tape (T) at a front portion of the housing and an open position wherein the front (28) and back (32) lids are displaced from the opening and from the recording tape. The back lid is formed to leave a pair of gaps (a) near the ends thereof capable of accommodating passage of the recording tape (T) therethrough when the front and back lids are in the closed position so that, when the front and back lids are in the open position, a transducer can be introduced into or withdrawn from the housing and, when the front and back lids are in the closed position, the recording tape can be entered through the gaps (a) to a position within the housing and behind the back lid for co-operation within the transducer or be enclosed within the channel for protection. <IMAGE></p> |
