けたことを特徴とする電動ボリユーム駆動装置。[Claim for Utility Model Registration] The reference voltage for setting the operating position of the electric volume is set by selectively turning on a plurality of setting switches and connecting individual voltage dividing resistors to each of the switches. This reference voltage and an auxiliary reference voltage with a slight potential difference with respect to the reference voltage to prevent malfunction are input to each individual input terminal of the comparator, and the motor is operated in conjunction with the electric volume. The detected voltage from the detection volume is compared with the reference voltage and the auxiliary reference voltage in the comparator, and the driving of the motor is controlled so that the detected voltage is within the range of the reference voltage and the auxiliary reference voltage. An electric volume drive device characterized in that a resistance is provided between the detection volume and ground.
