Abstract:
1. A transfer apparatus comprising: a vacuum-forming chamber in which a transcription die and a forming product to which a pattern is transcribed from the transcription die are disposed face to face with each other; a movable body supporting one of the die and the forming product so as to allow the transcription die and the forming product to be movable closer to or away from each other; and a plurality of balance cylinders placed in parallel to a moving direction of the movable body and connected to the movable body via piston rods, respectively; a pressure detector detecting a pressure inside the vacuum-forming chamber; and a pressure control section changing the number of the balance cylinders to be actuated depending on an output of the pressure detector so as to cancel or reduce fluctuation in load acting on the movable body in the moving direction thereof due to pressure variation in the vacuum-forming chamber.
