Claims

[Scope of utility model registration request]

In a brake device that simultaneously applies brakes to stop a pair of reels rotating at high speed, a brake plate whose center portion is rotatably and slidably attached to the center line of the pair of reels is attached to the reel side. A brake arm is rotatably attached to the brake plate and has brake pads on both sides of the brake plate, and a spring is tensioned between the brake arms so that the brake pads are attached to the opposing surface from the center line of each reel. A reel brake device for a tape recorder, characterized in that the reel brake device comes into contact with the side.
