  • Patent number: 6643092
    Abstract: In a magnetic tape device, a tape cassette moving table 4 is placed between a pair of right and left guide plates 3a and 3b so as to be movable forward and backward (a and b). Rocking levers 8 which are engaged with the moving table 4, and a rotating cam 9 which is forward and reversely rotated by a driving source are interlockingly connected to each other via a slide plate 26. The rocking levers 8 are swung forward and backward (c and d) by the driving source via the rotating cam 9 and the slide plate 26 to move the moving table 4 forward and backward (a and b) between a cassette inserting position A and a cassette placing position B.

  • Publication number: 20030080229
    Abstract: A magnetic tape apparatus has an intermediate gear 19 meshed with an idler gear 22 which is releasably meshed with both a pay-off reel table 2 and a roll-up reel table 3, a drive gear 31 rotatably driven by a capstan motor 10, a driven gear 32 releasably meshed with the drive gear 31 by way of a friction plate, a clutch mechanism 20, and a speed increasing mechanism 27. The speed increasing mechanism 27 has a movable rotary body 37 rotatably mounted around a support shaft 36 and adapted to reciprocate along an axis of the support shaft 36 by means of the clutch mechanism 20. The movable rotary body 37 is provided with a small diametered gear 38 and a large diametered gear 39. In a fast feed mode and a rewind mode, the small diametered gear 38 is meshed with the drive gear 31 while the large diametered gear 39 is meshed with the intermediate gear 19.

  • Patent number: 6550711
    Abstract: A magnetic tape apparatus has an intermediate gear (19) meshed with an idler gear (22) which is releasably meshed with both a pay-off reel table (2) and a roll-up reel table (3), a drive gear (31) rotatably driven by a capstan motor (10), a driven gear (32) releasably meshed with the drive gear (31) by way of a friction plate, a clutch mechanism (20), and a speed increasing mechanism (27). The speed increasing mechanism (27) has a movable rotary body (37) rotatably mounted around a support shaft (36) and adapted to reciprocate along an axis of the support shaft (36) by means of the clutch mechanism (20). The movable rotary body (37) is provided with a small diametered gear (38) and a large diametered gear (39). In a fast feed mode and a rewind mode, the small diametered gear (38) is meshed with the drive gear (31) while the large diametered gear (39) is meshed with the intermediate gear (19).

  • Patent number: 6398144
    Abstract: There are provided a mode switching member (1)movable between a stop mode position in which a brake for braking rotation of a reel table is operated and a quick forward/rewind mode position; an energizing mechanism (3) for elastically energizing, when the mode switching member (1) is in the quick forward/rewind mode, the mode switching member (1) toward the stop mode position; a holding mechanism (6) for holding the mode switching member (1) in the quick forward/rewind mode position against energizing of the energizing mechanism (3) and a hold releasing mechanism (7) for releasing the holding state of the mode switching member (1) by the holding mechanism (6) according to a stop instruction for operating the brake.
