PURPOSE:To reduce power consumption by integrally associating an X-axis movable element and a Y-axis movable element at mounting members provided movably in both X- and Y-axis directions on a pole surface. CONSTITUTION:The upper surface of a magnet 11 of rectangular parallelepiped shape becomes a pole surface 14 magnetized to become N-pole 12 and S-pole 13 alternately directed toward X- and Y-axis directions. A mounting member 16 is movably provided on the pole surface 14. An X-axis movable element 20 and a Y-axis movable element 21 are mounted on the lower surface of the mounting plate 17 of the member 15. The elements 20, 21 are composed of cores and exciting coils, both have the same construction, but the element 21 is arranged to perpendicularly cross the element 20. |
