摘要： A drive unit in accordance with the present invention is provided with a magnetic field generating member generating a magnetic field, a magnetic field detecting device constituted by first, second and third magnetic field detecting elements detecting the magnetic field, and a piezoelectric actuator moving the magnetic field generating member. When executing a relative positioning between the magnetic field generating member and the magnetic field detecting device on the basis of a detection result by the magnetic field detecting device, a first positioning is executed on the basis of the detection result of the first and second magnetic field detecting elements in a predetermined region, and a second positioning is executed on the basis of the detection result of the third magnetic field detecting element at a predetermined point apart from the predetermined region, within a movable range in which the magnetic field generating member moves. In accordance with the structure, it is possible to position the movable body at a high precision, even in the case that a plurality of position detecting points of the movable body of the drive unit exist at a wide interval.

摘要： Provided is a driving device having an electromechanical transducer, a driving member, a moving member and a driving circuit. The driving circuit outputs a driving voltage at a frequency lower than that where the driving speed of the moving member is at maximum, and changes the drive frequency of the driving voltage so that the drive frequency has a negative correlative relationship with the ambient ten aperature. The change rate of the drive frequency to a change of the ambient temperature in the negative correlative relationship is larger than a change rate of a frequency where the driving speed of the moving member is at maximum to an increase of the ambient temperature, and the change rate permits the driving speed of the moving member to increase when the ambient temperature increases.
