記録再生装置のリール台駆動機構。 A large gear and a small gear are integrally formed on a drive shaft that is supported by a bearing fixed to a chassis and rotationally driven by a motor, and a swing plate that is rotatably supported around the drive shaft engages with the small gear. The support shaft of the reduction gear that fits together and the support shaft of the speed-up gear that meshes with the large gear are fixed, and the first shaft is fixed to the shaft fixed to the chassis.
The intermediate gear and the second intermediate gear are supported in a friction transmission state through the side surfaces of each other, and the third intermediate gear is supported in a state of meshing with the first intermediate gear on a swinging arm shaft fixed to the chassis. , an oscillating arm that rotates when rotational torque is transmitted from the side surface of the third intermediate gear is rotatably supported on an oscillating arm shaft, and an idler gear that meshes with the third intermediate gear is fixed to the oscillating arm. The swing arm is rotatably supported on a shaft, and when the swing arm rotates, the idler gear selectively engages with a gear provided on the take-up reel stand or a gear provided on the supply reel stand, and the swing plate 1. A reel stand drive mechanism for a magnetic recording and reproducing apparatus, characterized in that a speed increasing gear and a first intermediate gear or a second intermediate gear and a reduction gear are selectively engaged with each other by being rotated by a rotating means.
