Abstract

PURPOSE:To reduce a load of a driving current generating circuit in a constant speed section, by constituting so that the gain of a control loop to a moving element in the section in which the moving element moves at a constant speed is controlled by making it lower than that in other section. CONSTITUTION:In accordance with oscillation in a constant speed section of a speed control signal (a), an acceleration end signal (b) forms a pulse train. A latching circuit 35 is set by being triggered by the first fall of this acceleration end signal (b). Subsequently, the latching circuit 35 is reset by being triggered by a fall of a deceleration signal (c) indicating a deceleration start time point. An output signal (d) of this latching circuit 35 falls when a moving element has rushed into the constant speed section, and rises when it has rushed into a deceleration section. This output signal (d) is used for the on-off control of a switch SW2, and when the switch SW2 is turned on, the gain of an amplifier 31, and the gain of a control loop to the moving element is made lower than that in other speed section.
