Abstract

PURPOSE: To attain a structure tolerant to external vibration and howing by supporting an arm itself completely without any mechanical contact place except the contact point of the stylus tip of a pickup cartridge with a record disk.
CONSTITUTION: Tone arm 4 is equipped with driving coils 5 and 6 for positioning at right angles to a record surface and Hall elements 7a and 8a that correspond to them. In addition, driving coil 9 determining a horizontal position on the record surface and corresponding Hall element 10a are provided. To arm 4, driving coil 11 is fitted by metal fittings 11a corresponding to beltlike permanent magnets 21 and 22 having surface magnetic poles 21a and 21b, and 22a and 22b different on the lengthwise center and the linear motor composed of them provides the x-directional motion. Thus, this device is supported without any mechanical contact position except the stylus tip of arm 4.
