ABSTRACT:
A transcript apparatus has a vacuum-forming chamber60in which a transcription die41and a forming product13transcribed from the die41are disposed face to face with each other, a movable body19supporting one of the die41and the product13to allow the die41and the product13to be movable closer to or away from each other, a balance cylinder50placed in parallel to a moving direction of the movable body19and connected to the movable body19via a piston rod52, a pressure detector64detecting a pressure inside the chamber60, and a pressure control section68operative to control a pressure of working fluid supplied to the chamber60depending on an output from the pressure detector64to cancel fluctuation in load acting on the movable body19in the moving direction thereof.
