<p>PROBLEM TO BE SOLVED: To provide an inserting operation assistant device which surely prevents erroneous arrangement by confirming a conduction pattern during inserting operation by a simple configuration.SOLUTION: An inserting operation assistant device 1 includes probe pins 31, a matrix output circuit 40, a control unit 36, a matrix input circuit 50, and a determination unit 37. The probe pins 31 are electrically connected to inserted electric wires 20 with terminals. The matrix output circuit 40 has a phototransistor 43 connected thereto for each of the probe pins 31. The control unit 36 connects the electric wires 20 with terminals connected to photocouplers 41, to a power source. A current detection unit detects a current which flows due to connection to the power source (a positive polarity-side power source 32 or a negative polarity-side power source 33) of each electric wire 20 with a terminal. The determination unit 37 determines which of a correct cavity or an erroneous cavity each electric wire with a terminal has been inserted to, on the basis of the detection result of the current detection unit and a preliminarily set conduction pattern.</p> |
