摘要： In a rolling driving actuator used as a drive source of a power toothbrush, permanent magnets are formed flat plate shape, and constituting a moving object by being attached to grooves formed on an outer peripheral face of a yoke which is press-fitted to and fixed on a shaft. On the other hand, a tubular shaped stator, which is constituted by a coil wound around a bobbin and stationary yokes provided on both side of the bobbin in axial direction of the shaft, is provided to face an outer face of the permanent magnet or an outer face of the yoke of the moving object with a predetermined clearance so that a center axis thereof becomes coaxial with the center axis of the shaft. By supplying an alternating current to the coil, the moving object is driven in rolling driving around the axis of the shaft.

摘要： In a power toothbrush, an interchangeable brush head is directly fitted to a front end portion of a drive shaft of an actuator. The actuator comprises a first magnetic circuit for moving the drive shaft reciprocally in an axial direction of the drive shaft, and a second magnetic circuit for rotating the drive shaft around a center axis of the drive shaft. The first magnetic circuit and the second magnetic circuit are independently excited by independent driving current having predetermined frequencies and a predetermined phase difference therebetween. Thus, the brush head fitted to the drive shaft can be moved in a composition of reciprocal linear movement and reciprocal rotation. The actuator does not include conventional mechanical elements such as gears or cams so that the actuator can move the drive shaft much faster than that of the conventional actuator.

摘要： An improved linear oscillating actuator is capable of minimizing the undesired vibrations while moving first and second oscillators in parallel paths. The first and second oscillators carry first and second drive elements respectively for driving connection to individual reciprocating loads. The first and second drive elements project upwardly respectively from the first and second oscillators such that the first drive element is disposed immediately upwardly of the second oscillator and the second drive elements is disposed immediately upwardly of the first oscillator. With this reverse arrangement of the first and second drive elements relative to the first and second oscillators, the individual oscillating systems each including the oscillator, the drive element and the corresponding reciprocating load can have its mass center disposed in close proximity to a mass center of the actuator, thereby enabling to reduce undesired vibrations which would otherwise occur around the mass center of the actuator.
