<p>PURPOSE:To use one set of motor for tape loading and unloading in addition to the drive of a capstan by always meshing the 1st and 2nd intermediate gears to a driven gear, and coupling a tape loading drive system to the drive gear. CONSTITUTION:The driven gear 403 is fitted to a shaft 11 and a spur gear meshing with the 1st and 2nd intermediate gears 3, 4 and a bevel gear meshing with other gear 405 are provided. The 1st and 2nd intermediate gears 3, 4 are fitted to the 1st and 2nd operating plates 6, 10 via shafts 7, 9, mesh always with the spur gear of the drive gear 403 and are constituted to be freely removed from the drive gear 401a. Then the peripheral speed of the drive gear 402a, the 1st and 2nd intermediate gears 3, 4 and the driven gear 403 is designed to be constant and the tape loading drive system is coupled to the driven gear.</p> |
