DEVICE AND METHOD OF MOVING AND CONTROLLING THE POSITION OF A SLIDABLE BODY SUCH AS USED FOR BODY CELANING

摘要

A leaf spring (42) is provided between the drum periphery and the slidable nozzle (4). The position control of the latter is performed by counting the frequency of the power circuit. The outputs shaft (11) of the motor has a specific rotating speed or angle relative to the frequency of the power source. The nozzle has a specific amount of axial reciprocating movement depending on the direction of rotation of the output shaft of the motor. The actual position of the nozzle can be determined by counting the frequency of the power source simultaneously with the rotation of the output shaft.
