Abstract
An endless-loop tape cassette includes an endless-loop magnetic tape; and a disk which has a portion of the magnetic tape wound in a stack thereon, and which is rotatable along with one of a supply reel shaft and a take-up reel shaft. In addition, a rotating member is provided, which is rotatable along with the other one of the supply reel shaft and the take-up reel shaft. A transmission mechanism transmits a rotary movement between the disk and the rotating member; and a backstop is engageable with at least one of the disk, the rotating member and the transmission mechanism.
Claims19
An endless-loop tape cassette comprising:
- an endless-loop magnetic tape;
- a disk which has a portion of the magnetic tape wound in a stack thereon, and which is rotatable along with one of a supply reel shaft and a take-up reel shaft;
- a rotating member which is rotatable along with the other one of the supply reel shaft and the take-up reel shaft;
- a transmission mechanism which comprises a gear and which transmits a rotary movement between the disk and the rotating member;
- and
- a backstop which is movable between an engaged position and a disengaged position, wherein in said engaged position said backstop engages at least one of the disk, the rotating member and the transmission mechanism to oppose rotation of said at least one of the disk, the rotating member and the transmission mechanism, and wherein said backstop moves from said disengaged position to said engaged position in response to a change in direction of rotation of at least one of the disk, the rotating member and the transmission mechanism.
