Abstract: A drive device which provides an electromagnetic impact and a movement mechanism using the drive device to achieve a reciprocating movement with a compact and simple configuration. A drive device provides an impact to an object-to-be-moved supported by a friction surface and moves the object-to-be-moved, and includes an electromagnetic coil, a permanent magnet, a stopper, and a control device which controls the electromagnetic coil. The permanent magnet relatively moves to the electromagnetic coil by an action caused by an electrical current supply to the electromagnetic coil. When the electrical current is supplied to the electromagnetic coil, the permanent magnet collides with the electromagnetic coil or the stopper, which forms the collided-body, and generates the impact. The impact can be generated in any direction, then a reciprocating movement of the object-to-be-moved can be achieved.

Abstract: A drive device includes two integrated electromagnetic coils separated on an axis, an elastic body, and two movable electric conductors. An object-to-be-moved is moved to left with an operation of a left group which includes one electromagnetic coil and one conductor. A first conductor is repulsively moved to right by a repulsion force caused by an eddy current generated on the first conductor with an electrical current-supply to a first electromagnetic coil and then, the elastic body is compressed by the first conductor and subsequently pushes back the first conductor. At this time, the electrical current-supply to the first electromagnetic coil is turned off, and the first conductor collides with the first electromagnetic coil, and this collision generates a leftward impact. The left and right groups enable a left-right reciprocating movement.
