A drive system for imparting motion to a treating implement such as a toothbrush or the like includes a cam rotatably driven around an axis of rotation by a motor. For instance the coupling device is a staple made of ductile metal having a body embedded in the support foot and two legs extending outward towards the chassis side of the support foot. Within the demarcated playing zone, free positive units combine with free negative units zone to form null units, with each null unit comprising an equal number of positive units and an equal number of negative units. The user side performs operations and processing based on the information for coping with the problem received from the maintenance service side, and solves the problem of the device. The first booster comprises a comparator that controls a boosting operation with reference to the fed back first high voltage and uses the second high voltage as a drive voltage.
