PURPOSE:To eliminate the need for a gear reducer mechanism and a small movement mechanism and to attain miniaturization and light weight of the titled driver while reducing the moving parts by using a shaking actuator turning and shaking a shaft and driving the shaft while constituting a magnetic circuit in radial direction of the shaft and delivering directly the change in the electromagnetic force through the control of a current flowing to a parallel coils provided in a magnetic field to the carrier. CONSTITUTION:The parallel coils 4 (4a, 4b) are inserted to surround a gap inner shaft 2 of a yoke 11 and a magnet 13 and the carrier 5 is connected directly to the coils 4. Magnets 13a, 13b are arranged so that different poles (N, S) are made adjacent and the magnetic flux density on the same circle in the gap is made constant, then the carrier 5 is driven straightforward in a direction in parallel with the shaft 2 along a straightforward guide slot 10 of a guide member 19 by changing the current flowing to the parallel coils 4. Thus, the carrier 5 is driven in two directions, that is, the turning and shaking movement around the shaft 2 and the straightforward movement in the parallel direction to the shaft 2. |
