Claims

[Scope of utility model registration request]

a DC motor that drives a load in the forward and reverse directions, and switching circuits for the forward and reverse sides that switch the direction of energization to the DC motor to drive the DC motor in the forward and reverse directions;
One side of the forward/reverse driving force of the load operation, which changes in magnitude depending on the forward/reverse direction of the DC motor, is connected to the switching circuit to make the amount of movement of the load the same with the same power supply waveform. What is claimed is: 1. A control circuit for driving a DC motor, comprising: a control circuit for driving a DC motor;
