PURPOSE:To display anything unusual in each apparatus itself so accurately as well as to aim at the promotion of promptitude in taking measures against it, by comparing a related apparatus function stopping state in time of trouble happening in any of these apparatus with a stored pattern, while displaying the trouble in regard to only such one that gets troubled. CONSTITUTION:At a central processing unit 6, trouble data is compared with a function stopping pattern of related apparatus prestored in a data read-only memory 8 in time of trouble happening, and such one that is congruent with it is judged, finding out the real apparatus that gets troubled and stopped its function, whereby an address of the data ROM8 storing the display details corresponding to the apparatus is selected, then display data of the address is transmitted to a displayer 13 from the ROM8 and displayed on a display part 14, while a buzzer 15 sounds, informing an operator of trouble happening there. Likewise, real trouble details and measures corresponding to the trouble signal fed to each of trouble signal lines S1-Sn are selectively displayed. Next, according to the measures, when reset switches 21-2n are pushed, they are compared with the trouble data of a random access memory 9, and when it is reset to a normal state, the next measures are displayed if there is no change in the trouble data of the display. |
