Title: Vcr with reel gear braking device
Inventor: YASUNARI ITSUKU
IPC: G11B15/22
Filed: 1996-09-27
Abstract: PROBLEM TO BE SOLVED: To provided a VCR provided with a reel gear braking device for generating optimum braking force by changing the restoration spring of a braking member for an elastic beam and installing an adjustment cam for finely adjusting the elastic force of the elastic beam. SOLUTION: When a user rotates the adjustment cam 130 of this VCR clockwise (arrow) from 0 deg. to 180 deg., a distance between a camshaft 133 and the elastic beam 119 is shortened. Thus, the elastic force applied to the braking member 110 by the elastic beam 119 is reduced and the braking force by an operation spring 107 is increased. When the user rotates the adjustment cam 130 counterclockwise from 0 deg. to 180 deg., the distance between the camshaft 133 and the beam 119 is increased. Thus, the elastic force applied to the member 110 by the beam 119 is increased and the braking force by the spring 107 is reduced. The spring 107 and the beam 119 exert contrary effects to the braking force since the moments of mutually opposite directions are made to act with the camshaft 113 as a center.
