PROBLEM TO BE SOLVED: To reduce a control burden of an external control device by recognizing whether or not a rotary rail turns in the advancing direction to a rail in which a traveling device exists at present by a detector by a change in output from a transmitting part in respective panels themselves. SOLUTION: A driving unit 4 and a microcomputer 5 are arranged in a panel 3 suspended and supported by a traveling device 2 to travel in a rail 1. A host computer 9 is connected to a rotary rail driving unit 11 to perform rotational control of a rotary rail 10. The traveling device 2 at traveling time stops once when reaching this side prescribed position of the rotary rail 10, and when a light receiving unit of the traveling device 2 detects the light from a floodlight, the microcomputer 5 sends out a signal to make the traveling device 2 travel. The traveling device 2 to which travel indication is given enters the rotary rail 10 as it is, and moves in the other rail 1 after being changed in the proper direction. Therefore, a control burden of an external control device can be reduced. |
