Abstract

PURPOSE:To omit exchange of keyboards by using a switch showing the installing state of a keyboard to use alternately two different types of keyboard faces attached to both sides of a keyboard. CONSTITUTION:A keyboard 1 contains a keyboard face 2 having an exclusive key array and a keyboard face 3 of a JIS array on both sides of the keyboard 1. An identification switch 4 is kept pushed while the face 2 is turned upside and then pushed up by a switch spring, etc., when the face 3 is turned upside respectively. A control part is stored in the keyboard 1 and connected to an equipment via a cable 5. The keyboard 1 usually carries out an exclusive job and therefore uses the face 2. Then the keyboard is turned over for application of the face 3 when a program is changed and corrected. In this case, the automatic switching operations are carried out by the switch 4 for control of both faces.

Description

【発明の詳細な説明】〔産業上の利用分野〕本発明はキーホードに関し、特に２つの異なる配列をも
ったキー盤面を１つの制御部で制御し、設置状態を示す
スイッチによって制御する、方法・構造に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a keyboard, and more particularly to a method and method for controlling keyboard surfaces having two different arrangements with one control unit and a switch indicating the installation state. Regarding structure.

[Conventional technology]

従来この種のキーボードは１つの配列のキー盤面しか持
っていなかった。Conventionally, this type of keyboard has had only one keyboard surface arrangement.

[Problem that the invention seeks to solve]

上述した従来のキーボードは１つの制御部に１つのキー
盤面しかないので、２つのキーボードを使用したい場合
は、既に取付けられているキーボードを取りはずし、別
のキーボードを新九に取付は直さなけれはならない。又
、取シはずしたキーボードを置く場所を用意しなければ
ならない。The conventional keyboard mentioned above has only one keyboard surface per control unit, so if you want to use two keyboards, you must remove the already installed keyboard and install another keyboard on the new nine. . Also, you must prepare a place to put the removed keyboard.

又、２つのキーボードをあらかじめ接続しておくという
事も可能であるが、この方法は同時に働く事のない２つ
のキーボードの為に、２つの制御部を必要とし、制御の
プログラムも２重管理しなければならないため、複雑化
し、コスト高になるという欠点がある。It is also possible to connect two keyboards in advance, but this method requires two control units for the two keyboards that do not work at the same time, and the control program is also managed twice. This has the disadvantage of complication and high cost.

[Means for solving problems]

本発明は、　　Ｚｆｆｉ類の配列を持ったキー盤面と、
これらを制御する制御部と、設置の状態により動作し、
制御部に対して、制御を可能とするスイッチを有してい
る。The present invention provides a keyboard surface having a Zffi type arrangement;
It operates depending on the control unit that controls these and the installation status,
The control unit has a switch that enables control.

〔Example〕

次に、本発明について図面を参照して説明する。 Next, the present invention will be explained with reference to the drawings.

第１図は本発明の一実施例を示す図である。キーボード
１は専用のキー配列を有するキー盤面２と。FIG. 1 is a diagram showing an embodiment of the present invention. The keyboard 1 has a keyboard surface 2 having a dedicated key arrangement.

ＪＩＳ配列のキー盤面３とが表と裏に背中あわせで接続
された構造になっている。又、キー盤面２が上に置かれ
ている時は押し込まれておシ、キー盤面３が上の時は、
スイッチのバネ等により、押し上げられる状態になる識
別スイッチ４がある。It has a structure in which the keyboard surface 3 of the JIS layout is connected back to back on the front and back. Also, when keyboard surface 2 is placed on top, it is pushed in, and when keyboard surface 3 is placed on top,
There is an identification switch 4 that is pushed up by a switch spring or the like.

制御部はキーボード１に内蔵され、ケーブル５によって
装置と接続される。The control unit is built into the keyboard 1 and connected to the device via a cable 5.

通常は、専用業務を行なりので、専用キー盤面を使用す
る。又、プログラムの変更・修正等を行なう時は、キー
ボードを裏がえし、ＪＩＳキー盤面を使用する。この時
、キーボードを裏かえすのみで、識別スイッチにより、
盤面の制御が、自動的に切換えが行なわれる。Normally, a dedicated keyboard surface is used because it is used for dedicated work. Also, when changing or modifying a program, turn the keyboard over and use the JIS keyboard surface. At this time, just flip the keyboard over and use the identification switch to
Control of the panel is automatically switched.

〔Effect of the invention〕

以上説明したように本発明は２′ｓ類の異なったキー盤
面を表裏におき、設置状態を示すスイッチにより、２つ
のキー盤面を交互に使用できるので、従来の様にキーボ
ードを取シかえが不要であシ、使わないキーボードの為
に置場所を用意しなくても良く又、２つのキーボードを
あらかじめ接続する方法と比較して、簡略化し、コスト
ダウンをはかれるという効果がある。As explained above, in the present invention, the different keyboard surfaces of the 2's type are placed on the front and back, and the two keyboard surfaces can be used alternately by a switch that indicates the installation state, so it is not necessary to change the keyboard as in the conventional case. There is no need to prepare a place for a keyboard that is not needed or used, and compared to the method of connecting two keyboards in advance, it is simpler and has the effect of reducing costs.
