<P>PROBLEM TO BE SOLVED: To provide a deterioration diagnosis device of a moving handrail of a passenger conveyor, that can attain deterioration diagnosis by change of a color tone of the surface of a moving handrail. <P>SOLUTION: In the deterioration diagnosis device of the moving handrail of the passenger conveyor, a personal computer 10 extracts a deviation of a color tone of the surface of a moving handrail 1, which is obtained from photographed images of first cameras 2 and 3, from a color tone of a surface of a preset new moving handrail and performs an operation for specifying a position of the moving handrail 1 in the photographed images photographed by the first cameras 2 and 3 when the deviation exceeds a preset threshold being a value considered as generation of deterioration. When the specified position of the moving handrail 1 reaches a set position of a radiation device 8, a driving signal is output to a driving control part 12 of the radiation device 8 to transmit a radiation through the moving handrail 1, display processing control of a radiation transmitted image photographed by a second camera 7 is performed, and the radiation transmitted image is displayed on a monitor 11. <P>COPYRIGHT: (C)2013,JPO&INPIT |
