Claims

[Scope of utility model registration request]

a first rotating body that rotates independently of tape running; a second rotating body that is supported coaxially with the first rotating body and rotates integrally with the first rotating body with a predetermined frictional force; , a drive mechanism for a tape recorder comprising a rotational force transmission mechanism that selectively transmits the rotational force of the second rotating body to a pair of reel stands, wherein one of the first and second rotating bodies A shaft having a substantially cylindrical shape and having a groove along the circumference at the tip is formed in the center of the rotating body, and a through hole through which the shaft is inserted is formed in the center of the other rotating body, and the shaft It is approximately ring-shaped and has an engaging portion on its periphery. a friction member is interposed between the first and second rotating bodies, the shaft is inserted into the through hole, and the tip of the shaft inserted through the through hole is inserted into the elastic plate. The second through hole of the elastic plate is inserted into the first through hole and fitted into the groove of the shaft, and the engaging portion of the elastic plate is connected to the peripheral edge of the rotating body in which the through hole is formed. A drive mechanism for a tape recorder, characterized in that the drive mechanism supports the first and second rotating bodies by engaging with the parts.
