Abstract

PURPOSE: To secure a smooth operation without giving any shift to the signal transmission line led from the deflected angle detecting means, by mounting a control circuit to the shift component to give a control to the coil current of a mobile coil type linear motor which surves as the driving source.
CONSTITUTION: The arm holder 2 supporting the pickup arm 1 in a free rotating way is supported by the shift component 4 which can move freely along a pair of guide rails 5a and 5b made of the conductive material. The coil 8 is provided to the component 4, and at the same time the control circuit 12 of the coil 8 is incorporated to supply the power source E via the rails 5a and 5b. On the other hand, the magnet 9 is provided to the yoke 10 fixed to the base 11 and in opposition to the coil 8, and the magnetic flux of the magnet is interlinked to the coil 8. Accordingly, the connection of the control line to the coil 8 can be done only within the mobile part 4, thus ensuring a smooth shift. As a result, an assured tracking control is possible.
