<p>PURPOSE:To drive a cassette and a tape with one motor by moving a cassette holder to a recording/reproducing position by a first rack part of a tray to complete loading (LD) of the cassette and next driving a tape loading means by a second rack part to load the tape. CONSTITUTION:A cam gear 12 is rotated by the operation of a motor 23, and a first rack part 8 moves a cassette holder 4 to the recording/reproducing position by a pinion to complete loading of the cassette, and a tray 6 is stopped because the pinion is meshed with a second rack part 9 following the rack 8. The rack 9 is continuous to the rack 8 and is extended on a locus which has a shaft 17 of a oscillating plate 16 as the center and has a uniform radius, and the gear 12 is continuously turned; and when the pinion is meshed with the rack 9, the plate 16 is turned, and a tape loading means 20 is driven by a gear part 19 to load the tape. The motor 23 and the gear 12 are reversed and the plate 16 is driven to perform the unloading operation, and the pinion is meshed with the rack 8 thereafter to perform the eject operation, and the device is returned to the initial state. Thus, the constitution is simplified and the reliability is improved.</p> |
