Claims

[Scope of utility model registration request]

It is equipped with a magnetic head and is slidable back and forth between a first position where the magnetic head is in contact with the magnetic tape, allowing playback, and a second position where the magnetic head is spaced apart from the magnetic tape and allows high-speed feeding. a pulley that is rotatably disposed on the head chassis, is in pressure contact with a belt connecting the motor pulley and the flywheel in the second position, and is spaced apart from the belt in the first position; It comprises a pulley and a high-speed transfer gear that is arranged to be able to transmit rotation at all times and constitutes a high-speed transfer mechanism together with the pulley, and when the head chassis is in the first position, the pulley is separated from the belt and the high-speed transfer mechanism is activated. The motor is separated from the carbstan drive system and the load on the motor is reduced, and when the head chassis is in the second position, the pulley is pressed against the belt to increase the belt tension and the wrapping angle of the belt with respect to the motor pulley. A drive transmission mechanism for a tape recorder, etc., configured to increase drive transmission torque and obtain the driving force of a high-speed transfer mechanism.
