磁石３，４を中央に停止させることができる。 The operation of the drive device configured as described above will be briefly described below. First, when the permanent magnets 3 and 4 move to the mechanical stop position, the two solenoid coils 1 and 2 apply force to the permanent magnets in the same direction (at this time, the solenoid coils 10 and 11
(no current needs to flow). When moving from the mechanical stop position to the position (indicated by the broken line) where the magnetic forces of the two solenoids 1 and 2 cancel each other out, at the beginning of the movement, the two solenoid coils 1 and 2 apply force in the same direction to the permanent magnet. The current direction of the solenoid coil 2 is changed at an appropriate time using the switch 10, a force in the opposite direction is applied to the permanent magnets 3 and 4, and the permanent magnets 3 and 4 are braked. , 13 to generate a force that attracts the permanent magnets, the permanent magnets 3, 4 can be stopped at the center by using the switches 9, 11 to flow current in a direction that generates a force that attracts the permanent magnets to the permanent magnets 3, 4.
従つて、本実施例では、従来に比べて一ケ所永
久磁石３，４の停止位置が増えることになる。 Therefore, in this embodiment, the number of stopping positions of the permanent magnets 3 and 4 is increased by one compared to the conventional one.
なお、本実施例ではソレノイド１２，１３を中
央部に設けたが別に中央部でなく、ソレノイド

いうまでもない。 In this embodiment, the solenoids 12 and 13 are provided in the center, but it goes without saying that the same effect can be obtained even if the solenoids 12 and 13 are provided between the solenoids 1 and 2 instead of in the center.
