ABSTRACT:
A brake device for a VCR rapidly stopping the rotation of the supply reel and the take-up reel and reducing the number of brake shafts and brake springs. The brake device includes a supply reel soft brake and a supply reel main brake which are rotatably mounted on a common shaft at a side of the supply reel for braking the supply reel. A take-up reel soft brake and a take-up reel main brake are rotatably mounted on a common shaft at a side of the take-up reel for braking the take-up reel. The brake device further includes a pair of brake springs. One of the brake springs is mounted on the common shaft at the side of the supply reel and biases the supply reel brakes in opposed directions in order to make these supply reel brakes come into close contact with the supply reel. The other spring is mounted on the common shaft at the side of the take-up reel and biases the take-up reel brakes in opposed directions in order to make the take-up reel brakes come into close contact with the take-up reel.
