たことを特徴とする電動ボリユーム駆動装置。 The reference voltage for setting the operating position of the electric volume is set by selectively turning on a plurality of setting switches and inserting and connecting individual voltage dividing resistors with each of the switches. An auxiliary reference voltage with a slight potential difference to prevent malfunction is input to each individual input terminal of the comparator, and the detection voltage from the detection volume operated by the motor in conjunction with the electric volume is detected. Comparing with the reference voltage and the auxiliary reference voltage in the comparator,
In an electric volume drive device that controls driving of the motor so that the detected voltage is within a range of the reference voltage and the auxiliary reference voltage, each of the electric volume sets a minimum value and a value close to the minimum value of the electric volume. An electric volume drive device characterized in that a resistor is provided between the switch and the input terminal of the auxiliary reference voltage of the comparator so as to be inserted and connected when the corresponding switch is turned on.
