ABSTRACT:
A VCR having a capstan brake device has a flywheel having a friction plane on the lower portion thereof. The flywheel is installed to one end of a capstan shaft piercing through a chassis, and a brake member is installed to one side of the flywheel for swinging toward the friction plane. The brake member is installed with a hinge-coupled fixing rod and a fixedly-coupled operating rod and support rod. The support rod sets the brake member to an applying state by a spring, and the operating rod sets the brake member to a releasing state by a cam having a guide groove and an operating groove. Thus, rotating speed of the flywheel is constantly decelerated, and the operation of the brake member is promptly and accurately carried out.
