Abstract
Abstract A working apparatus includes a pair of supports which are provided on a base, and a pair of parallelly disposed linear servo-motors each of which is settled on each of the supports. Sliders of the linear servo-motors support the ends of a beam so that the beam extends perpendicular to the servo-motors and is moved according to the simultaneous movements of the sliders. Another linear servo-motor is provided on the beam, and the slider of this motor bears a working head. The working head is moved along the beam in accordance with the slider movement.
