Side wall sections (15) contiguous to both sides of the front wall section are provided towards the rear side of said body member (3) in parallel. Said lid (11) is openably and closably mounted through rotary shafts (16) supported by bearing means (12a, 17) mounted inwardly of said side wall section (15) of the lid (11). Reel lock means (21 - 30) to lock a pair of tape reels (4, 5) during non-use is provided between side wall sections (13, 14) of said body member (3) and said bearing means (12a, 17) each of a pair of reel lock levers (21) being rotated by an actuating boss (29) provided to each of said shafts (16, 30) pressing an actuating lug (28) against an urging means (27) as a result of the opening of the lid (11) for disengaging said tape reel (4,5) for allowing free rotation by means of a rotatable locking finger (22). …<??>Thus a very compact and tough cassette is provided, wherein there is no risk that the lid be inadvertently opened when the cassette is inserted into or taken out of the device and the stable lid closing state may be assured. |
