ABSTRACT:
A therapeutic bed is arranged so that its inclination is adjusted by a bed inclination adjusting device provided to a rotation drive device disposed in a Y-direction moving device. The bed inclination adjusting device supports the therapeutic bed at three points by its three inclination adjusters. Each of the inclination adjusters converts the rotation of a motor into the rectilinear motion of a slider, and varies the level of a universal joint provided to the therapeutic bed by a support rod rotatably attached to the slider. This allows the inclination angle of the therapeutic bed to be varied. The provision of the bed inclination adjusting device reduces the number of drive devices for positioning the therapeutic bed, thereby decreasing the cumulative value of errors in all drive devices.
