<p>PURPOSE:To simplify the structure, to reduce the number of parts and to make a cassette player small and thin by holding a second moving gear separated from a main gear by means of a cam gear provided for the purpose of moving a first moving gear. CONSTITUTION:Moving gears 38, 64 are arranged between transmission gears 36, 37 and a main gear 33. At the FWD or REV moving time, the gear 38 is meshed with the gear 36 or 37 to transmit the rotation of the gear 33 to a driving gear 34 of a winding hub shaft or a driving gear 35 of a feeding hub shaft. At the FF or REW moving time, the gear 64 is engaged with the gear 36 or 37 to transmit the rotation of the gear 33 to the gear 34 or 35. A gear 50 for driving a cam gear 45 is provided between the cam gear 45 and the gear 33. When a to-be-pressed element 71a is pressed by a pin 57c at a part of a lock lever 57 as the lock of the gear 45 is released, an arm plate 71 is rotated against the force of a spring member 74, so that the gear 64 is disengaged from the gear 33. The state is maintained by the gear 45.</p> |
