<p>PURPOSE:To simplify the structure and to secure the operation by driving a cassette loading motion with a partial untoothened gear and providing a turning arm for interception of the transmission of a rotational force at a sliding part at the time of tape loading operation. CONSTITUTION:The rotation of a motor 3 is transmitted from a drive gear 6b to a driven gear 8b, and hence a cassette holder 2 is guided to a loading position in a deck by turning a turning arm 8, so that a tape loading position in a deck by turning a turning arm 8, so that a tape loading operation is performed via a gear 13. At the time of tape loading, a pressurized sliding circumferential part 6c is rotated in slide contact with a sliding contact part 8c and stopped on completion of the tape loading in a position at that time. At the time of unloading, the reverse rotation takes place, and an completion, the sliding contact part 8c is released from the contact with the pressurized sliding circumferential part 6c, so that the driven gear 8b is reversely driven by the drive gear 6b and then the cassette holder 2 is brought back to its starting position.</p> |
