PURPOSE:To make the operation of an arm easy and to prevent the occurance of unexpected failures, by making coincidence a normal arm and an operating level for the direction of position, in the remote operation of the arm located at a remote position. CONSTITUTION:An electric signal from an arm driving detector 3 and a knob driving detector 8 is inputted to a servo circuit 11, and a selsyn circuit 12 is turned off if there is a difference between two input signal values, and a DC motor 9 is rotated until the difference of signal value is gone out to drive knob 5. Further, the position of the knob 5 is mde to the same position of an arm 1 and the circuit 12 is turned on when the position of the arm 1 and the knob 5 is the same. Moreover, a motor 2 is rotated according to the produced pulses from a circuit 5 via a circuit 12, allowing to make the same for the positio of the knob 5 and the arm 1 at all times. |
