本発明はPOS端末装置に関し、特にキーボードと、C
RT等の表示画面とを含むPos端末装置に関する。Detailed Description of the Invention Technical Field The present invention relates to a POS terminal device, in particular a keyboard and a C
The present invention relates to a POS terminal device including a display screen such as RT.
従来技術
従来、この種のPOS端末装置は、−旦電源を投入する
と、その後は常に一定の輝度によりCRT上に情報を表
示していた。つまり、キーボードを操作しているとき、
操作していないときによらず、CRTの輝度は一定であ
った。PRIOR ART Conventionally, this type of POS terminal device, once powered on, always displayed information on a CRT at a constant brightness. In other words, when operating the keyboard,
The brightness of the CRT remained constant regardless of when it was not being operated.
しかしながら、CRTの輝度を一定とすることは、キー
ボードを操作していない場合にも電力か消費されること
を意味し、経済上好ましくないという欠点があった。ま
た、CRTに文字等が焼付いたり、CRTの寿命を縮め
たりする原因になるという欠点もあった。However, keeping the brightness of the CRT constant means that power is consumed even when the keyboard is not being operated, which is economically undesirable. Further, there is also the drawback that characters, etc. may be burned onto the CRT, and the life of the CRT may be shortened.
発明の目的
本発明は上述した従来の欠点を解決するためになされた
ものであり、その目的は消費電力を抑え、CRTの焼付
き、さらにはCRTの寿命の短縮化を防止することがで
きるPOS端末装置を提供することである。Purpose of the Invention The present invention was made in order to solve the above-mentioned conventional drawbacks, and its purpose is to provide a POS system that can reduce power consumption, prevent CRT burn-in, and further shorten the life of the CRT. The purpose is to provide a terminal device.
発明の構成
本発明によるPOS端末装置は、キー入力手段と、所定
輝度で情報を表示する表示手段とを含むPOS端末装置
であって、前記キー入力手段についての操作が所定時間
断状態となったとき前記所定輝度より低い輝度で情報を
表示するよう制御する輝度制御手段を有することを特徴
とする。Composition of the Invention A POS terminal device according to the present invention is a POS terminal device including a key input means and a display means for displaying information at a predetermined brightness, and the operation of the key input means is interrupted for a predetermined period of time. The present invention is characterized by comprising a brightness control means for controlling the information to be displayed at a brightness lower than the predetermined brightness when the information is displayed.
実施例 以下、図面を用いて本発明の詳細な説明する。Example Hereinafter, the present invention will be explained in detail using the drawings.
第1図は本発明にょるPos端末装置の一実施例の内部
構成を示す概略図である。図において、本発明の一実施
例にょるPos端末装置1は、キホード4と、CRT2
と、輝度制御回路3とを含んで構成されている。FIG. 1 is a schematic diagram showing the internal configuration of an embodiment of a Pos terminal device according to the present invention. In the figure, a POS terminal device 1 according to an embodiment of the present invention includes a keyboard 4 and a CRT 2.
and a brightness control circuit 3.
キーボード4は、オペレータ等の操作により各種の情報
を入力するためのものであり、複数の押しホタンスイッ
チから構成されている。The keyboard 4 is used to input various information through operations by an operator, and is composed of a plurality of pushbutton switches.
輝度制御回路3は図示せぬタイマを含んで構成されてお
り、CRT2に表示すべき情報の輝度を決定する回路で
ある。また、そのタイマはキーホト4による入力か所と
なっている時間を計時するものであり、その計時値が一
定値に達したときCRT2に表示すべき情報の輝度を下
げるように本回路は動作する。The brightness control circuit 3 includes a timer (not shown), and is a circuit that determines the brightness of information to be displayed on the CRT 2. In addition, the timer measures the time input by the key photo 4, and when the measured value reaches a certain value, this circuit operates to lower the brightness of the information to be displayed on the CRT 2. .
かかる構成において、キーボード4による入力が10分
間断状態となったときに輝度を下げるように輝度制御回
路3内の図示せぬタイマが予め設定されているものとす
る。In this configuration, it is assumed that a timer (not shown) in the brightness control circuit 3 is set in advance to lower the brightness when input from the keyboard 4 is interrupted for 10 minutes.
ます、装置の電源をオンすることにより、装置が使用可
能状態となる。この状態において、キーホード4による
操作か可能となり、キ、ボード4をオペレータ等か操作
しているときには輝度は何も変化せず、一定の輝度にて
情報を表示する。First, by turning on the power of the device, the device becomes ready for use. In this state, operations using the keyboard 4 are possible, and when the keyboard 4 is being operated by an operator or the like, the brightness does not change at all, and information is displayed at a constant brightness.
ところが、キー操作を中断し、その中断時間か上述した
10分間に達したとき、すなわち、タイマの計数値が1
0分間を示したとき輝度制御回路3か動作し、輝度を下
げて表示する。一方、再びキーボード4の操作を開始す
ると、これに応答して輝度を上げ、もとに戻すように輝
度制御回路3が動作する。However, when the key operation is interrupted and the interruption time reaches the above-mentioned 10 minutes, that is, the count value of the timer becomes 1.
When 0 minutes is indicated, the brightness control circuit 3 operates to lower the brightness and display. On the other hand, when the user starts operating the keyboard 4 again, the brightness control circuit 3 operates to increase the brightness and return it to the original level in response.
つまり、キーボードの操作か予め設定された時間以上中
断すると、自動的に輝度か下がり、丙び操作を開始する
ともとの輝度に戻すのである。こうすることにより、消
費電力を抑え、CRTの焼付き、さらにはCRTの寿命
を延ばすことができるのである。In other words, if keyboard operations are interrupted for more than a preset period of time, the brightness is automatically lowered, and then returned to the original brightness when the keyboard operations are resumed. By doing so, it is possible to suppress power consumption, prevent burn-in of the CRT, and further extend the life of the CRT.
なお、輝度制御回路3内の図示せぬタイマはキホート4
の操作に応答して計時値がリセットされるように構成し
、さらにそのタイマの計数値とrめ定められた値とを比
較する比較回路をオペアンプ等で構威し、この比較回路
の出力値に応じて通常輝度と低輝度とを切換えるよにし
ておけば良く、当業者に容易に構成できる。また、輝度
を下げるたけてなく、零、すなわち表示を消しておくと
いう方式や、操作中断時間に応じて多段階に輝度を順次
低下させていくという方式も考えられる。Note that a timer (not shown) in the brightness control circuit 3 is a Quijot 4.
The timer is configured so that the time value is reset in response to the operation of the timer, and furthermore, a comparator circuit is constructed using an operational amplifier or the like to compare the count value of the timer with a predetermined value, and the output value of this comparator circuit is It suffices to switch between normal brightness and low brightness depending on the situation, and can be easily constructed by those skilled in the art. Further, a method in which the brightness is not lowered to zero, that is, the display is turned off, or a method in which the brightness is sequentially lowered in multiple stages depending on the operation interruption time is also conceivable.
さらにまた、タイマの計数値と比較される設定時間につ
いては、予め設計段階において値を決定し、メモリ等に
記憶しておくという方式や、キーホードの操作によって
オペレータの希望する任意の値に設定できるようにする
という方式が考えられる。Furthermore, the set time to be compared with the timer's counted value can be determined in advance at the design stage and stored in memory, or can be set to any value desired by the operator by operating a keypad. One possible method is to do this.
また、本発明はPOS端末装置についてのものであるが
、CRTを含む各種の装置に本発明を応用できることは
明らかである。さらに、CRT以外の表示装置、例えば
周知の液晶表示装置、周知のブラスマディスプレイ装置
にも本発明が適用できることは明らかである。Further, although the present invention relates to a POS terminal device, it is clear that the present invention can be applied to various devices including a CRT. Furthermore, it is clear that the present invention is applicable to display devices other than CRTs, such as well-known liquid crystal display devices and well-known plasma display devices.
