<p>PURPOSE: To provide a current control type controller for plural adjusting elements by a control computer at low costs. CONSTITUTION: Only one measurement resistance is serially connected with other control transistors 20-22 so that a measuring and controlling circuit part for all adjusting elements 10-12 can be formed. Each individual control transistor 20-22 for each adjusting element 10-12 is serially connected with a resistance, and the resistance value of the resistance is made correspond to the resistance value of the measurement resistance. This device is provided with switching means 14-16 which are controlled by a control computer 13, and the adjusting elements which are normally serially connected with the belonging individual control transistor are sequentially continously connected serially with the measuring and controlling circuit part in a prescribed measuring and adjusting time by the switching means 14-16. A control signal series adjusted in the other control transistors to one of the adjusting elements during the measuring and adjusting time is also supplied to the belonging control transistors.</p> |
