Abstract
Abstract In a video signal reproducing apparatus, a cantilevered bi-morph leaf is secured at one end to a rotary support, for example, a rotary portion of a guide drum about which a magnetic tape is helically wrapped, a transducer is mounted at the other end of the bi-morph leaf for reproducing a video signal recorded in one of a plurality of successive parallel tracks extending obliquely across the magnetic tape with the transducer being deflectable transverse to the direction of the tracks upon flexing of the cantilevered bi-morph leaf from a rest condition, and a damper is engageable with the other end portion of the bi-morph leaf for dampering free oscillations due to bending forces applied to such leaf.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
156 words
A system for reproducing a video signal recorded in successive parallel tracks on a recording medium, said system comprising: rotary support means, bi-morph leaf means, mounting means securing one end portion of said bi-morph leaf means to said rotary support means with said bi-morph leaf means being cantilevered therefrom so as to be movable by flexing from a rest condition in either direction transverse to the direction of said tracks, signal reproducing means for reproducing a video signal in a respective one of said tracks and being connected with the other end portion of said bi-morph leaf means so as to be movable therewith, and damper means in addition to said mounting means and being engageable with said other end portion of said bi-morph leaf means at a distance along the latter spaced from said mounting means for damping free oscillations of said bi-morph leaf means due to bending forces applied to said bi-morph leaf means.
Claim 2
Independent Claim
156 words
A system for reproducing a video signal recorded in successive parallel tracks on a recording medium, said system comprising: rotary support means, bi-morph leaf means, mounting means securing one end portion of said bi-morph leaf means to said rotary support means with said bi-morph leaf means being cantilevered therefrom so as to be movable by flexing from a rest condition in either direction transverse to the direction of said tracks, signal reproducing means for reproducing a video signal in a respective one of said tracks and being connected with the other end portion of said bi-morph leaf means so as to be movable therewith, and damper means in addition to said mounting means and being engageable with said other end portion of said bi-morph leaf means at a distance along the latter spaced from said mounting means for damping free oscillations of said bi-morph leaf means due to bending forces applied to said bi-morph leaf means.
Claim 3
Dependent Claim
36 words
A system for reproducing a video signal according to claim 1; wherein said damper means bears against said other end portion of the bi-morph leaf means in directions normal to the direction of said flexing thereof.
Claim 4
Dependent Claim
28 words
A system for reproducing a video signal according to claim 1; wherein said damper means consists of two damper members between which said bi-morph leaf means is sandwiched.
