Claims

[Scope of utility model registration request]

In order to drive the magnetic tape, the magnetic tape is attached to a capstan shaft that rotates with rotational force from a motor to drive the magnetic tape. The pinch roller, which is pinched and pressed, is rotated by the rotational force of the capstan shaft, and the rotational force is transmitted to the reel via an idler device that rotates toward the left and right reels by a friction member. A reel drive device for a magnetic recording and reproducing device, characterized in that the reel drive device comprises:
