Claims

[Claims for Utility Model Registration] (1) A flywheel is integrally disposed on a capstan, and a capstan pulley that is drive-coupled to a drive motor is coaxial with the capstan and relative to the flywheel. A tape recorder characterized in that it is arranged so as to be relatively rotatable by an arbitrary swing angle. (2) A protrusion is provided on the flywheel, the capstan pulley is rotatably arranged relative to the capstan, and the capstan pulley has an arc-shaped elongated hole into which the protrusion is inserted. The tape recorder according to claim 1 of the utility model registration claim, characterized in that the tape recorder is provided with a perforation. (3) The tape recorder according to claim 1, wherein a projection is provided on the flywheel, and an engaging projection is provided on the capstan pulley so as to come into contact with the projection. . (4) The cam body is oscillated in accordance with the direction of rotation of the drive motor, and the cam body, which is oscillated in one direction by the forward rotation of the drive motor, is used to hold the magnetic tape between the pinch rollers and the capstan. Claims 1 to 5 are characterized in that the pinch roller is separated from the capstan by the cam body which is brought into elastic contact with the capstan and swung toward the other side by the reverse rotation drive of the drive motor. Any of the tape recorders described in paragraph 3.
