Abstract
In an industrial machine, the work safety is further improved by eliminating blind spots from an image displayed on a monitor. A hydraulic excavatorwhich is the industrial machine is equipped with monitoring camerasF,B,L,R mounted in the respective places of a revolving upperstructurein order to capture images for monitoring. A monitordisplays camera imagesF,B,L,R obtained by the cameras as well as an icon imageC of an image illustration of the hydraulic excavator. The camerasF,L,R are mounted at the distal ends of support armsF,L,R to be located in positions jutting from a revolving upperstructure main unitof the revolving upperstructure, so that a hidden area under the underside of a catwalkprovided on the revolving upperstructurefalls within the field of view.
