Two-axial rotational driving apparatus and driven member rotation control system

摘要

A two-axial rotational driving apparatus is disclosed which achieves a small size and rotational driving with a well-balanced arrangement and higher accuracy. The two-axial rotational driving apparatus comprises a first actuator (102) which rotationally drives a support member (115) on which a driven member (105) is mounted around a first axis through a first rotation member (104), a second actuator (101) which rotationally drives a second rotation member (103), a converting mechanism (109,110) which converts rotation of the second rotation member (103) into rotation around a second axis to rotate the support member (115) around the second axis.
