PROBLEM TO BE SOLVED: To provide an unmanned conveyance system comprising two areas, and capable of reducing power consumption for driving an electric magnet disposed on an unmanned conveyance vehicle.SOLUTION: An unmanned conveyance system comprises a first area and a second area. A guidance guide line 9 comprises a first guide line disposed on a floor face of the first area and formed of a magnetic material, and a second guide line disposed on a floor face of the second area and formed of a magnetic permeable material. An unmanned conveyance vehicle comprises: an electric magnet 7; a yoke part 8 in which magnetic from the electric magnet 7 passes through the second guide line, and a magnetic sensor 6 detects the magnetic from the second guide line; and a control part 10 for controlling drive of the electric magnet 7. The control part 10 stops the electric magnet 7 when the unmanned conveyance vehicle travels on the first area, and drives the electric magnet 7 when the unmanned conveyance vehicle travels on the second area.SELECTED DRAWING: Figure 2 |
