Claims

[Scope of utility model registration request]

In a tape recorder that takes out a tape from a tape cassette such as a digital audio tape cassette mounted on a reel and winds it around a rotating head for recording and playback, a cam gear having a cam and gears is rotated by a motor, and the first rotation of the cam gear is performed. In the process, either the cam or the gear moves the moving guide pin that pulls out the tape and the pinch arm having the pinch roller to wrap the tape around the rotary head and bring the pinch roller close to the capstan shaft, and the cam gear 1. A pinch roller pressing device for a tape recorder, characterized in that the pinch roller is pressed against the capstan shaft by moving the pinch arm with the other one during the second rotation process.
