Abstract

PURPOSE:To eliminate the scattering of thrust, and to improve the accuracy of positioning by dividing a magnetic pole core for a slider while displacing the pitch of a scale tooth section. CONSTITUTION:The two magnetic pole cores 13, 14 with the same form, which are magnetically separated in the rectilinear direction to the progressive direction of the slider 12 and opposed, are mounted. A permanent magnet 17 is crosslinked to the backs of each magnetic pole core 13, 14 while arranging different polarity to each magnetic pole core 13, 14, and the corresponding tooth section magnetic poles 13a-13d, 14a-14d of each magnetic pole core are opposed so as to generate the displacement of the half pitch of the scale tooth sections 11a, 11b to the scale tooth sections 11a, 11b. Accordingly, since magnetic path length containing the permanent magnet is made constant, the scattering of thrust is eliminated about respective step based on the changeover of excitation to a coil, and the accuracy of positioning is improved.
