PROBLEM TO BE SOLVED: To display many items of information on the screen of a monitor panel with respect to the conditions of a construction machine and anomalies thereof without miniaturizing individual display components. SOLUTION: When a displayed picture changes to an anomaly displaying picture 21, if a switch means 21f on the picture 21 is operated, the picture 21 is kept fixed for a prescribed period of time (two minutes, for example). Further, an anomaly displaying picture 21' may be kept fixed until a switch means 21h for release on the picture 21' is operated. Furthermore, when a monitoring displaying picture 11 and anomaly displaying pictures 21, 22, and 23 are cyclically displayed, if a switch means 21g on the picture 21 is operated, the displayed picture on this display device is returned from the picture 21 to the picture 11, and the picture 11 is displayed for a prescribed period of time (five minutes, for example). Further, it is also possible to hold the state of the displayed picture returned to the picture 11.
