Abstract

PURPOSE:To simplify a circuit construction by a method wherein bridge circuits for rotating a plurality of motors in forward and backward directions have one side in common. CONSTITUTION:A motor 1 is connected between output terminals of the first bridge circuit consisting of transistors 7, 3, 4, 6, while a motor 2 is connected between output terminals of the second bridge circuit consisting of transistors 7, 3, 23, 24, and a motor 3 is connected between output terminals of the third circuit consisting of transistors 7, 3, 27, 28. When the potential at a rotation direction change-over terminal a12 is zero, the transistors 7, 6 are turned ON and the motor 1 is rotated in the forward direction. When the potential exceeds VBE, the transistors 7, 3, 4, 6 are all turned OFF and the motor 1 is stopped. When the potential exceeds 2VBE, the transistors 3, 4 are turned ON and the motor 1 is rotated in the backward direction. When the potential at a terminal b1 is made to be zero, the motor 1 is stopped forcibly.
