<p><P>PROBLEM TO BE SOLVED: To provide a conveying carriage capable of stably performing two-way communication between a conveying carriage main body and a lift body. <P>SOLUTION: In an OHT conveying carriage 1 travelling on a rail 3, communication and power supply between a suspending mechanism 10 of a carriage main body 1a and the lift 34 is performed by a signal line 13 and a power line 14 of a communication/power supply section 50. The signal line 13 is provided with a signal line 13a connected to optical element modules 6a and 6b, which are mounted on a rotating board 5 provided in a driving shaft 22, and a control circuit 46 of the lift body 34, and a signal line 13b connected to optical element modules 7a and 7b, which are mounted on a fixed board 4 provided at a position opposite to the rotating board 5, and a control circuit 16 of the suspending mechanism 10. Two-way optical communication is performed between the optical element modules 6a and 6b, and the optical element modules 7a and 7b to secure communication between the control circuit 16 of the suspending mechanism 10 and the control circuit 46 of the lift body 34. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
