よシ、可動子３はＥまたは反Ｅ方向に移動する。(Prior Art) FIG. 1 shows a conventional linear drive mechanism. Reference numeral 1 denotes a stator made of a magnetic material, which has grooves 2 at equal intervals and extends in a straight line. Reference numeral 6 denotes a movable element, which is movable by the moving vehicle 4 in the forward direction or the B direction. A transparent photosensor 5 can be seen on the side of the mover 6, and the stator 1
By detecting the number of slits or the amount of light on a slit plate arranged parallel to the slit plate, the position of the -movement element can be determined. Figure 2 is a sectional view taken along the line ■-■ in Figure 1, and as shown in the figure, the mover 3 is wound around a U-shaped yoke 7.8, a permanent magnet 9, a yoke 10, and a yoke 7.8. It consists of turned coils 11 and 12. The pitch between the teeth of the yoke 7.8 is different from the pitch between the teeth 1-1 of the stator 1. Now, if a current is applied to the coil 11 in the C direction and the coil 12 is not energized, as shown in FIG. A magnetic loop 16 like this is generated and becomes stable in this state. Next, when a current is applied to the coil 12 in the D direction and the current to the coil 11 is cut off, the movable element 6 moves one step in the E direction and stabilizes in that state. Next, when a current is applied to the coil 11 in the F direction, the movable element 6 moves one step in the E direction. In this way, the movable element 3 moves in the E direction or in the opposite E direction to control the energization to each coil.

位置ずれは非常むずかしかった。In such a conventional example, the position of the movable element 6 is detected by a slit plate separate from the stator as described in the SIJ. However, with this method, it is not only very difficult to align the groove 2 or the tooth 1-1 formed on the stator side, but also the slit plate 2 (the slit plate 2 is very difficult to align). Absolute positional deviation due to the accumulation of pitch errors was extremely difficult.
