An automatic wire end arranging system includes a wire holder for holding one ends of the wires, a wire feed device for feeding the wire ends one by one from the wire holder, and a transport device for transporting each wire end from the wire feed device to an arranging device. The arranging device includes a fixture having a plurality of parallel receptive sections, and a table mounted adjacent to the fixture and having a slit, a probe device operable to make electrical contact with the wire end, fed to the table by the transport device, to feed a probe signal, a first drive device operable to move the table, a second drive device operable to bring the wire end on the table into alignment with the slit, and a third drive device operable to urge the wire end, disposed in alignment with the slit, into a selected one of the receptive sections through the slit. A control device, to which the other ends of the wires are electrically connected, is responsive to the probe signal to operate the first drive device to move the table, thereby bringing the slit into alignment with the selected receptive sections corresponding to the probed wire. The control device is responsive to the probe signal to operate the second and third drive devices to bring the wire end into alignment with the slit and to urge the wire end into the selected receptive sections through the slit.
