置に関する。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a status display device for an electronic device that displays current status output and past history status output within the electronic device.
従来の技術
従来、この種の状態表示装置は、第２図に示すように、
入力端子１に入力された現在の状態の出力を表示器３に
表示する回路４と、この現在の状態の出力を記憶手段と
してのラッチ回路２に記憶しておき、表示器５に過去の
履歴の状態の出力として表示する回路６とが、それぞれ
独立に構成されていた。BACKGROUND OF THE INVENTION Conventionally, this type of status display device, as shown in FIG.
A circuit 4 displays the output of the current state inputted to the input terminal 1 on the display 3, the output of this current state is stored in the latch circuit 2 as a storage means, and the past history is displayed on the display 5. The circuits 6 for displaying the output of the state are each configured independently.
発明が解決しようとする課題
しかしながら、上記従来の状態表示装置では、回路がそ
れぞれ独立に構成されているため、現在の状態の出力を
表示する表示器３と過去の履歴の状態の出力を表示する
表示器５が別々に必要となり、表示部分が大きくなると
いう問題があった。Problems to be Solved by the Invention However, in the conventional status display device described above, since the circuits are each configured independently, the display 3 displays the output of the current status and the output of the past history status. There was a problem that a separate display device 5 was required and the display area became large.
本発明はこのような従来の問題を解決するものであり、
装置の小型化・簡易化を図ることを目的とするものであ
る。The present invention solves these conventional problems,
The purpose is to make the device smaller and simpler.
課題を解決するための手段
本発明では、上記目的を達成するために、現在の状態の
出力と過去の履歴の状態の出力を切換えて１つの表示手
段に供給する切換手段を具備したものである。Means for Solving the Problems In order to achieve the above object, the present invention is equipped with a switching means for switching between the current state output and the past history state output and supplying the same to one display means. .
作 用
従って、本発明によれば、現在の状態の出力と過去の履
歴の状態の出力を切換手段で切換えて表示手段に供給す

器である。Embodiment FIG. 1 shows the configuration of an embodiment of the present invention. In FIG. 1, 11 is an input terminal into which the current state such as a control signal to be displayed is input, 12 is a latch circuit as a storage means for storing the current state and outputting it as a past history state, and 13 is a latch circuit. A total changeover switch as a switching means for switching between the output of the current state and the output of the past history state;
Reference numeral 14 denotes a shared display that displays the output of the current state selected by the changeover switch 13 and the output of the past history state.
次の上記実施例の動作について説明する。現在の状態の

供給される。Next, the operation of the above embodiment will be explained. The current state output is directly from one fixed terminal 13a of the changeover switch 13.
and is also supplied to the latch circuit 12. The past history state output from the latch circuit 12 is supplied to the other fixed terminal 13b of the changeover switch 13.
従って、切換えスイッチ１３の可動接点１３ｃを固定端
