ELECTROMAGNETIC ACTUATOR AND INPUT DEVICE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an electromagnetic actuator used by being incorporated into input devices or the like of various kinds of electronic apparatuses and an input device using the electromagnetic actuator, which can efficiently save electric power.SOLUTION: A plurality of first friction plates 42 subjected to a rotation regulation in the rotational direction of a rotation axis 90 and movable on the thickness side is arranged overlapping with a plurality of second friction plates 46 co-rotationally engaged with the rotation axis 90 movable to the thickness side on a case 30 having a cylindrical part 20 as a storage part. Further, the first friction plate 42 or the second friction plate 46 in a close contact with the movable member 50 is depressed by movably arranging the electromagnetic movable member 50 in the axial direction of the rotation axis 90 and putting the case 30 and the movable member 50 into a suction state by the magnetic flux generated on current application to a coil 65 and shifting a gap between the first friction plate 42 and the second friction plate 46 into a close contact state, thereby constituting an electromagnetic actuator 10 or an input device 100 using the electromagnetic actuator.SELECTED DRAWING: Figure 1
