Abstract
A motor itself has multi-functions to be able to drive a plurality of objects to be controlled, so that the whole apparatus is compact and provided at low cost. The rotation planes of first and second rotating units B1 and B2 are faced with each other to make these planes in a mutually pressed state. A current is supplied to a piezoelectric element provided on the rotation plane of any one or both of the first and second rotating units, and the rotation of any one of the first and second rotating units is selectively stopped by pressing members, so that any one of the rotating units can be selectively rotated.
