Abstract

PURPOSE:To simplify the operation of normal and reverse switching time by connecting a diode between the collector of a transistor flowing a current through a motor and the base of a controlling transistor and connecting a resistor circuit between the motor and a power source. CONSTITUTION:Transistors TrQ1, Q3, Q5 or TrQ2, Q4, Q6 are energized by a signal A or B, thereby flowing a normal or reverse current in a motor M to rotate the motor in normal or reverse direction. Diodes Da, D2 are connected between the bases of the TrQ1, Q2 and the collectors of the TrQ6, Q5. Since other sets of the Trs are not conducted ON even if the other signal (B or A) becomes H level when one signal (A or B) is H level, it can prevent the shortcircuit of the power source. When a resistor R9 is connected between the motor M and the power source and the motor is converted from the stop state to normal or reverse rotation, diodes D1, D2 are reversely biased to effectively conduct the respective Trs ON.
