Abstract

A display controller of a construction machine, which allows an operator's compartment to have more room so that the operator can work more efficiently. The controller comprises a plurality of controllers (20, 22, 25) for controlling the operations of various sections of the construction machine according to information acquired from detector means provided on the corresponding sections, and a display device (26) for displaying the conditions of those sections of the construction machine. The controllers and the display device are connected through a common communication line (30). The display device (26) comprises input means (28) for instructing the switching of information indicating the conditions of the construction machine sections, and display means (27, 29) for reading display information corresponding to the instruction from the controller to display it.
