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.
Claims11
A VCR having a capstan brake device comprising:
- a flywheel being formed integrally with a capstan shaft extending through a capstan hole of a chassis, said flywheel having a friction plane on a lower portion thereof;
- a brake member installed to one side of said flywheel for swinging toward said friction plane;
- a fixing rod having one end fixed to the lower portion of said chassis, and the other end hinge-coupled to said brake member;
- and
- swing means for swinging said brake member.
A VCR having a capstan brake device comprising:
- a flywheel being formed integrally with a capstan shaft extending through a capstan hole of a chassis, said flywheel having a friction plane on a lower portion thereof;
- a brake member installed to one side of said flywheel for swinging toward said friction plane, said brake member having a pad at one end thereof for applying a frictional force;
- a fixing rod having one end fixed to the lower portion of said chassis, and a second end hinge-coupled to a central area of said brake member;
- an operating rod having one end fixed to said brake member between said fixing rod and said pad on said brake member, and a second end of said operating rod passing through a center hole formed in said chassis;
- a rotatable cam mounted on said chassis, and having a surface in engagement with said second end of said operating rod, said cam surface formed with a guide groove shaped as a predetermined circular arc having a predetermined angle with respect to an axial line thereof, said second end of said operating rod extending into said guide groove, said guide groove having its bottom surface slanted toward one end of said arc, the depth of said guide groove being deepest at said one end of said arc, said guide groove defining an operating groove formed in a portion of said guide groove at said one end of said arc, said operating groove being deeper than said guide groove;
- a spring installed between said brake member and said chassis;
- and
- a support rod having one end fixed to an end of said brake member, end forming a hook after passing through said support rod disposed in the center of said spring and having a second end extending through a side hole formed in said chassis, said second end formed in the shape of a hook .
