PURPOSE:To allow the transit to manual operation without the change in feeling of operation even with added manual operation for automatic control, by stopping a motor if the difference between a fadar lever driving signal and an effective control signal is kept for a certain time for a prescribed value. CONSTITUTION:A resistance change of a variable resistor 2 connected to a rotating shaft of a fadar lever 1 is transmitted to an effect control signal generating circuit 3 and an effect control signal according to the rotating angle is produced. The fadar lever 1 is connected to a motor 6 via a friction clutch 5, a fadar control signal inputted to a terminal 10 and the effect control signal are compared at a comparison circuit 7 and a motor driving circuit 8 rotates the motor to the specified position according to the difference. The output of the comparison circuit 7 is transmitted to a motor stop signal generating circuit 9, and if the difference is greater than the specified value and it continues for a prescribed time, it is judged that the manual operation is applied, and stop signal is transmitted to the motor driving circuit 8 to stop the motor 6. |
