Abstract

PURPOSE:To prevent the breakdown of a circuit by a method wherein, when control signals for normal and reverse revolution are inputted at the same time, one of the signals is cancelled. CONSTITUTION:When voltage is applied on a terminal A, transistors Q2 and Q3 are turned to ON position and a motor M revolves normally. Also, when voltage is applied to a terminal B, transistors Q1 and Q4 are turned to ON position and the motor M revolves reversely. On the other hand, when the voltage is applied to both terminals A and B, a protective transistor Q5 is turned to ON position by the aid of the voltage of the terminal A and the transistor Q4 is turned to OFF position. As a result, the motor M revolves normally in the same way when the voltage is applied to the terminal A only. Through these procedures, the breakdown of the circuit due to an erroneous handling can be prevented.
