<p>PURPOSE:To protect a tape by providing a winding-up means which rotates payoff or take-up reels in such a direction that a tape-like body is wound up, and preventing the tape-like body from being loosed even if a cassette is unloaded. CONSTITUTION:A supporting part 14 is provided to an internal side surface of cassette case body 13, and levers 15 and 16 constituting a bent rotating member supported by the supporting part are provided. Then, the lever 16 is connected to the internal side surface of the case body 13 by a spring 17. Consequently, as the cassette is inserted as shown by an arrow 19, one end surface 18 of the cassette body 1 abuts on the lever 16 and the lever 15 rotates to abut on the gear 3a of a take-up reel. The gear 3a rotates to wind up a magnetic tape.</p> |
