PURPOSE: To enable automatic operation and manual operation to be cooperatively operated by operationally controlling a drive source for moving a support means in a horizontal surface by either of a manual operation command and an automatic operation command.

CONSTITUTION: When an intensifying means is to be manually operated, at least the motor 12c of a take-up mechanism 12 is drivingly controlled by manually operating a handle 12, and meanwhile, other motors 5, 6' and 9 are not energized at all, or a clutch is cut off so as to allow them to be freely rotated. On the other hand, in order to operate the intensifying means as an automatic robot, an angle sensor 13 by an angle detector such as an encoder and the like and distance sensors 14 and 15 by a distance detector are provided for a motor 5 for the turning shaft VI of an arm mechanism A', a horizontal slider 61 and a vertical slide member 8, so that a control system is made up for drivingly controlling the motor 12c of the take-up mechanism 12, the motor 6' of the horizontal slider 61 and the motor 5. In this place, a sensor 16 detects the turning angle of a support section 10.
