Document Type and Number:
Japanese Patent JPS5942072
Kind Code:
Y2
Abstract:
A record player for use with a stationary conventional record disc having a spiral sound groove with signals recorded therein includes a freely movable body which is placed on the record disc, a drive assembly for causing the movable body to effect random movements over the record disc, a pick-up or cartridge pivotally mounted at the underside of the movable body to pivot about a pivot axis for engaging the sound groove and reproducing the signals recorded therein while tracking the spiral sound groove as the movable body travels on the record disc, and a guide assembly for controlling the travel of the movable body relative to the record disc in response to pivotal movement of the pick-up. The guide assembly includes a guide wheel disposed in advance of the pivot axis so that the guide wheel provides a radial inward force to compensate for centrifugal forces acting on the movable body in moving in a generally circular path defined by turns of the spiral sound groove.
