To enable an article to be rotated with a simple structure in two directions of a circumferential angular direction and an elevation angle direction, and to further eliminate the disturbance of this rotation by wirings connected to the article in the case of the rotation.

A motor 1 for driving in a circumferential angle direction drives a mounting base 2 in the circumferential angle direction. A motor 3 for driving in an elevation angle direction is connected to the base 2. A camera unit 4 is fixed to the base 2, and is driven in the circumferential angle direction and the elevation angle direction as the base 2 rotates. The unit 4 is connected to and fixed to the drive shaft of the motor 2 via a shaft 5.
