PROBLEM TO BE SOLVED: To form a controller performing various and many kinds of information by letters by forming it on a display capable of displaying an information mechanism by the letters, selecting a memory and display data stored in the memory and providing a processing means for setting display sequence to be displayed. SOLUTION: When an abnormality occurs in an acceleration sensor, the display of 'acceleration sensor is abnormal' is performed, and when a boom sensor is abnormal, the display of 'boom sensor is abnormal' is performed. In the case of the abnormality occurrence of a changeover valve for a boom, the display of 'boom solenoid valve is abnormal' is performed. In the case where disconnection occurs in the changeover valve for the boom, the display of 'boom solenoid valve is disconnected' is performed. In other words, in the case where inconvenience having a fear interfering with working occurs, priority display processing is performed on the whole face of a liquid crystal display prior to basic display processing. The controller discriminates from the inconvenience occurring therein and a device D displays by transmitting it to the device D through a circuit L. Thereby the information of various and many kinds of contents can be rationally formed by letters.
