With this configuration, the supporting arm rotating device can be collectively arranged at a position below each supporting rod, and the supporting arm rotating device includes lifting drive means for one lifting platform and the centering shaft. It is only necessary to provide a single rotation driving means for rotating around the device, so that the entire apparatus can be made compact and inexpensive. In addition, since the rotation operation pin is projected from the rotating body that rotates about the centering shaft, when the support arm is rotated by the rotation operation pin, the rotation center of the rotation operation pin is set to the support arm. There is no danger of deviation from the rotation axis, and the support arm can always be smoothly rotated.
