Abstract

With a simple operation of inputting the target movement amount for the stage through the input device as input data, an acceleration signal is output from the control device to the acceleration/deceleration device based on the input data, and then n×T seconds after the acceleration signal is output, a deceleration signal having the same waveform as that of the acceleration signal and an opposite direction thereto is output.
