Abstract

PURPOSE:To obtain the operation of a long stroke in small size and low power by dividing a coil into a plurality of coils, selecting the coil interlinked with magnetic flux and conducting electricity. CONSTITUTION:The coil 1 is divided into plural number, and the coil 1 is supplied with driving currents by means of a power amplifying section 7. That is, a coil section corresponding to the position of a track is detected by means of a track position detecting section 8, two elements among switching elements 6-1- 6-5 in a switch group 6 used are selected by means of a decoder 9, and driving currents are fed by means of the power amplifying section 7.
