【発明が解決しようとする課題】上記従来技術は、表示
装置の特に球切れに主眼をおいたものであり、最近の複
雑化した表示装置は必ずしも表示灯が点灯できない故障
だけではなく、点灯したままとなる故障に対しては検出
できない問題があった。SUMMARY OF THE INVENTION The above-mentioned prior art focuses on a display device, particularly, a bulb break, and a recent complicated display device is not limited to a failure in which the display lamp cannot be turned on, but is turned on. There was a problem that could not be detected for the remaining failure.
【０００４】本発明の目的は、表示灯が点灯できないこ
とと合わせて表示灯が点灯したままとなる故障も検出で
きるようにすることにある。An object of the present invention is to detect a failure in which the indicator lamp remains lit as well as the failure to illuminate the indicator lamp.
【０００５】[0005]
【課題を解決するための手段】本発明は、現在の表示状
態の逆の表示を指令することで上記目的を達成する。The present invention achieves the above object by instructing a display opposite to the current display state.
【０００６】[0006]
【作用】現在の表示状態が消灯であれば点灯を、点灯し
ている状態であれば消灯を指示することで、故障してい
なければ表示状態が変化し、故障していれば表示状態が
変化しないことで判別できる。[Operation] If the current display state is off, it is turned on, and if it is on, the light is turned off so that the display state changes if there is no failure, and the display state changes if there is a failure. You can tell by not doing it.

とになる。Reference numeral 1 is a display signal device for outputting a normal display signal, and 2 is a button operated by an administrator who detects a failure by a failure detection command device. Reference numeral 3 is a failure detection signal generator, and the built-in logic element 3a outputs the signal 1 to the display device 4 by inverting the signal 1 when the signal 2 is not operating, and the signal 3b inverting the signal 1 when 2 is operating. . If the input signal is operating on the display device 4, the indicator lamp is turned on, and if the input signal is not operating, the indicator lamp is turned off. Normally, 2 does not operate, so 3b is not output, and conversely, 3a does not input 2 and outputs the signal 1 at the normal time to 4. However, when 2 is operated to detect a failure, the display signal 1 is inverted and output to 4, so that a display opposite to the display that has been displayed up to now is displayed.
【００１０】本実施例において故障検出指令装置を時計
等を使って自動的に指令することも可能である。また、
表示灯の数が多い場合は、故障検出信号生成装置におい
て表示灯を同時に故障検出しないで１個又は数個単位で
時分割で行うことにより故障検出時における表示灯に流
れる電流を押さえることも可能である。In this embodiment, the failure detection command device can also be automatically commanded by using a clock or the like. Also,
When the number of indicator lamps is large, it is possible to suppress the current flowing through the indicator lamps at the time of failure detection by performing time division in units of one or several lamps without simultaneously detecting the indicator lamps in the failure detection signal generator. Is.
【００１１】本実施例によれば、表示灯が点灯したまま
の故障についても検出することができる。According to the present embodiment, it is possible to detect a failure even when the indicator lamp is still lit.
