摘要：PURPOSE: To improve operation efficiency and to reduce power consumption, by a method wherein coupling means using a piezoelectric element is introduced between first and cond rotors, and its power supply mechanism is formed of a spring and a slide electrode. CONSTITUTION:A coupling means 23 is interpod between a first rotor 21 and a cond rotor 22, and electric energy is supplied to a piezoelectric element of the coupling means 23 from a terminal 24 mounted on a mirror cylinder fixing frame 14 as support frame through a power supply mechanism 30. The first and cond rotors 21-22 constitute a rotor 20, and corresponding to this a stator 10 comprising a piezoelectric element 11 and a vibration element 12 is presd. The coupling means 23 is constituted in that a bimorph type piezoelectric element 40 is enclod in a recess 41 formed on the cond rotor 22 and a basic portion 40a is fixed, and an engaging member 42 is installed on the first rotor 21. At manual operation state, current supply to the piezoelectric element 40 is interrupted and coupling with the engaging member 42 is relead. As a result, driven bodies 16, 22 can be easily rotated and driven by manual operation.
