An object of the present invention is to provide the rotary drive system, which is capable of controlling the rotational angle of the rotor with higher accuracy and which is made small in size. In the rotary drive system of the present invention, a moving body being capable of moving in a two dimentional plane. Driving means moves the moving body. A ring bearing is formed into a ring and provided in a plane parallel to the two dimensional plane. A rotor is held by the ring bearing and capable of rotating about own axis. A guide section is provided on one face of the rotor and arranged in a radial direction with respect to the axis of the rotor. A connecting member is provided to the moving body, capable of rotating about own axis parallel to the axis of the rotor, connected with the guide section, and capable of moving in the longitudinal direction thereof, whereby the connecting member and the guide section rotate the rotor with the movement of the moving body. <IMAGE> |
