Abstract
A supply reel brake mechanism for a VCR which carries out the supply reel braking operation through the use of a groove formed in a loading cam and a tension spring. In accordance with the invention, there is provided the brake mechanism wherein the movement of a brake is hindered by the recovering force of the spring and a second guide pin and a hinge having a spaced relationship with each other during a loading or unloading mode of the VCR, and the brake is operated by a position of a leg of the brake depending upon the rotation of the loading cam and the recovering force of the spring during the operating modes of the VCR.
Claims4
A video cassette recorder incorporating therein a supply reel brake mechanism Which includes a main chassis having a first and a second guide pins fixed thereto, and a sub-chassis slidably movable forward and backward with respect to the main chassis and having a first and a second rectilinear slots in which the guide pins are inserted, and a supply reel rotatably mounted on the sub-chassis and having teeth formed on its outer periphery, said supply reel brake mechanism comprising:
- a loading cam having a boss, a spiral inner protrusion, and a generally C-shaped outer protrusion defining a groove among them;
- a brake pivotable about a hinge fixed to a mounting member of the sub-chassis and including a rack for engaging the teeth of the supply reel, an extension downwardly extending from the brake and having a folded-in edge for slidably contacting with the second guide pin, a leg downwardly extending from the brake and slidably movable along an arcuate slot formed in the sub-chassis;
- and
- a tension spring fixed to the sub-chassis at its one end and fixed to the brake at its the other end for pivoting the brake counterclockwise.
