する磁気記録再生装置のテープ駆動機構。[Scope of Claim for Utility Model Registration] In a tape drive mechanism of a magnetic recording/reproducing device that pulls out a magnetic tape from a tape cassette and runs it along with a rotating magnetic head, a first gear that meshes with a take-up reel and a device that is coaxial with the first gear are provided. A winding gear having an integral second gear, a third gear driven by a reel driving motor, and a fourth gear meshing with the second gear are disposed vertically on the same axis, and a It is equipped with a limiter gear that generates a winding torque, and a shifter that is driven by a drive motor when switching modes, and a lever rotatably provided on the same axis as the winding gear is connected to a spring member through a sliding member. Therefore, the shifter is in pressure contact with the take-up gear, and the shifter is formed with a regulation groove that engages with one end of the lever to restrict rotation of the lever, and the one end of the lever is provided with a regulation groove of the shifter. An engaging portion is formed at the other end to engage with the
forming a lock portion that locks the third gear by meshing with the gear portion of the third gear, and when rewinding the tape, generates a first brake torque on the take-up reel by the pressure contact force of the spring member; During tape rewinding and playback, the lever is rotated by the rotation of the take-up gear to lock the third gear, and the take-up torque of the limiter gear is transmitted to the take-up gear to cause the take-up reel to receive the second tape. A tape drive mechanism for a magnetic recording/reproducing device characterized by generating brake torque.
