Patent number: 4032158Abstract: A tone arm for a record player having a mirror at one end is provided. Opposite the mirror are a light source and two detector elements. When the tone are pivots from a desired angle light from the source is reflected upon the element more than on the other. The mirror is convexly curved so that pivotal motions of the tone arm in one plane will not affect the amount of light reaching the detectors.Type: GrantFiled: September 3, 1975Date of Patent: June 28, 1977Assignee: Strathearn Audio LimitedInventors: Colin Howard Stanwell-Smith, Dexter Robert Plummer, Frederick James Easthope, Jonathan Humfrey Pope
