Abstract

PURPOSE:To simplify the system of the subject driving circuit as well as to eliminate the variation of speed in the positive and reverse revolution directions by a method wherein the positive and reverse direction circuits are formed separately, the y are operated by positive and reverse revolution signals, and a rotational speed control circuit is commonly used. CONSTITUTION:The positive revolution driving circuit 4 and the reverse revolution circuit 5 are independently constituted, and a DC motor is connected in between them. On each of the driving circuits 4 and 5, input transistor circuits 41 and 51, to be used to receive a positive revolution signal 2 or a reverse revolution signal 3, driving transistor circuits 42 and 45, and current application transistor circuits 43 and 53 are provided. Besides, a speed controlling circuit 6, containing a speed generator, which is directly connected to a DC motor 1, is provided and the positive and reverse revolution transistor circuits 42 and 52 are controlled by commonly using said controlling circuit 6.
