Claims

[Scope of utility model registration request]

An inclined post stand driving arm, a pinch roller crimping arm, and a drive gear are provided coaxially, and the inclined post stand driving arm and the pinch roller crimping arm are urged by a spring and pressed against a protrusion provided on a drive gear boss,
As the driving gear rotates until the tilted post base contacts the stopper, the tilted post base drive arm drives the pinch roller arm to the recording/playback standby position, and as the drive gear further rotates to the recording/playback position, the pinch roller A pinch roller crimping mechanism of a magnetic recording/reproducing device that presses a pinch roller arm with a crimping arm to press the pinch roller against a capstan.
