PROBLEM TO BE SOLVED: To shorten the wiring time and dispense with a connection diagram, by driving a laser pointer, based on the information on connection of a cable inputted into an arithmetic unit, and indicating the position of an instrument, the position of a terminal, and others. SOLUTION: A laser pointer 3 is a laser beam indicator which indicates the mounting position of a wiring instrument 2 or the position of a terminal outputted from a laser pointer 3 or an arithmetic unit 5, and a driver 4 is a device which controls the direction of application of a laser pointer 3 by the output signal from the arithmetic unit 5, being connected to the arithmetic unit 5. That is, the shortening of wiring time and the disuse of a connection diagram can be made by inputting the information of connection on electric wiring into the arithmetic unit 5 by a key board 6, operating the driver 4, based on the operation result, performing instructions, and directing the laser pointer 3 toward the wiring instrument 2, a terminal block, etc., at the destination of connection. |
