摘要: A mechanical gearing with a first rotatable member, three spherical balls in contact with and rotated by the first member, a second relatively flexible member in contact with the balls and a third rigid member fixed with respect to the second member and against which the second member is urged by the balls so that the second and third members rotate with respect to each other.

摘要: A combination of a turntable for playing phonograph records, a lid covering the turntable, tone arm for tracking record grooves, and a cleaning element mounted on the lid for movement into contact with a constant annular area on the top side of the record for cleaning. A counterbalance weight controls the pressure of the cleaning element upon the record.

摘要: 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.
