ため表示管の寿命が短くなるという欠点があった。[Problems to be Solved by the Invention] - When the performance of the conventional display device mentioned above deteriorates a little, the display becomes visibly legible but light input is not possible. This had the disadvantage of shortening the lifespan of the display tube, since it was necessary to increase the brightness.
本発明の目的は、」−述の欠点を改善しまたディスジ１
ノイ装置を提供する、二とにある。The object of the present invention is to improve the above-mentioned drawbacks and to
It is located in the second place, which provides the Neu equipment.

ライトペンの押下位置の検出を容易にするごとを特徴と
している。The present invention provides means for detecting depression of a light pen on the surface of a display tube of a display device, and a means for detecting depression of a light pen on the surface of a display tube of a display device, and a means for detecting depression of a light pen on a display tube surface of a display device in a disk radical operated with a light pen. 1. A means for increasing the display brightness on the screen of the official display tube only when is pressed.
It is characterized by making it easy to detect the pressed position of the light pen.
次に本発明の実施例について図面を参照して説明する。 Next, embodiments of the present invention will be described with reference to the drawings.
第１図は本発明の一実施例を示すブロック図である。こ

２および制御部６にそれぞれ接続されている。FIG. 1 is a block diagram showing one embodiment of the present invention. This display device includes a display tube 1, a brightness adjustment section 2 for adjusting the brightness of the display tube, a volume 3 for instructing the brightness of the brightness adjustment section, and a light vent section 5 constituting a light pen having a built-in switch 4. and a control section 6 that is connected to a computer system and controls the display tube 1. The switch 4 of the light pen section 5 is connected to the brightness adjustment section 2 and the control section 6 through a signal line 7, respectively.
−以上のような構成のディスプレイ装置において、表示
管１は制御部６からの指示により文字又は図を表示する
が、通常その輝度はボリューム３の指示により輝度調整
部２が調整している。- In the display device configured as described above, the display tube 1 displays characters or figures according to instructions from the control section 6, and the brightness is normally adjusted by the brightness adjustment section 2 according to instructions from the volume control section 3.
表示管１の画面にライトペンを押下するとスイッチ４が
オンとなり、スイッチ信号が信号線７に送り出される。When the light pen is pressed down on the screen of the display tube 1, the switch 4 is turned on and a switch signal is sent to the signal line 7.
輝度調整部２がスイッチ信号を受信すると、ボリューム
３で指定された輝度に対して高くなるようにあらかじめ
指定された輝度に画面を表示する。When the brightness adjustment unit 2 receives the switch signal, the screen is displayed at a pre-specified brightness higher than the brightness specified by the volume 3.
従って、表示管１の表示機能が劣化しても、ライトペン
の使用時は必ず表示管１の輝度が高くなるので、ライト
ペンの入力が常に可能となる。Therefore, even if the display function of the display tube 1 deteriorates, the brightness of the display tube 1 will always be high when the light pen is used, so that input using the light pen will always be possible.
なお、ライトベン部５のスイッチ４は、ライトペンの表
示管表面への押下を機械的に検出し得る機械的スイッチ
であっても、あるいはライトペンの表示管表面への押下
を電気的に検出し得る電気的スイッチであってもよい。Note that the switch 4 of the light pen unit 5 may be a mechanical switch that can mechanically detect when the light pen is pressed on the display tube surface, or it can electrically detect when the light pen is pressed on the display tube surface. It may be an electrical switch.
要は、ライトペンの押下を検知し、輝度調整部２に対し
て指示信号を発生し得るものであれば、いかなる種類の
ものであってもよい。In short, any type of device may be used as long as it can detect the depression of the light pen and generate an instruction signal to the brightness adjustment section 2.
さらに、本発明は上記実施例に限定されるものではなく
、本発明の範囲内で種々の変形、変更が可能なことはも
ちろんである。Furthermore, the present invention is not limited to the above embodiments, and it goes without saying that various modifications and changes can be made within the scope of the present invention.
以上説明したように本発明によれば、ライトペンを押下
している時のみ表示管の輝度を高くする回路を設けてい
るので、文字又は図の表示輝度が低い場合であっても、
ライトペンの押下位置を容易に検出できる。As explained above, according to the present invention, a circuit is provided that increases the brightness of the display tube only when the light pen is pressed down, so even when the display brightness of characters or figures is low,
The pressed position of the light pen can be easily detected.
さらに、常時表示管の輝度を高くしておく必要がないの
で、表示管の寿命が長くできるという効果がある。Furthermore, since it is not necessary to keep the brightness of the display tube high all the time, there is an effect that the life of the display tube can be extended.
