<p><P>PROBLEM TO BE SOLVED: To provide an actuator which can reduce the leakage of magnetic flux to the outside without narrowing the movable range of a plurality of coils and a coil fixing member even if the size is restricted. <P>SOLUTION: The first yoke plate 10 and the second yoke plate 20 are shaped like plates roughly square in external form, and are provided in roughly parallel with each other. The end of the first yoke plate 10 is provided with magnet screens 11-14. Magnets 31-34 are fixed to the face opposed to the second yoke plate 20 out of the two planes of the first yoke plate 10. Coils 41-44 are provided operably between the magnets 31-34 and the second yoke plate 20. Electromagnetic force arises in the coils 41-44 by the magnetic force generated by the magnets 31-34, and a tactual display member 70 supported by a fixing member 71 for fixing the coils 41-44 moves. <P>COPYRIGHT: (C)2004,JPO</p> |
