【発明の詳細な説明】
本発明は、コンピュータの電源スイッチ妬関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a computer power switch.
従来のコンピュータの電源スィッチは、特定のキーでし
か回転しない錠と連動して、電源のＯＮ。Conventional computer power switches operate in conjunction with a lock that can only be turned with a specific key to turn on the power.
０ＦＩｉ’を行なうだけであった。All I had to do was 0FIi'.
このため、電源投入後にコンソール等から種々の初期設
定を行なわなりれ０ならないという欠点があった。For this reason, there was a drawback that various initial settings had to be made from a console or the like after the power was turned on.
本発明の目的は、初期設定を自動的に行なうことができ
るコンピュータの電源スィッチを提供することにある。An object of the present invention is to provide a computer power switch that can automatically perform initial settings.
すなわち、本発明の目的ｔ」２、上述の欠点を除去する
ため、電源投入後に設定すべき情報を記憶しだ読出専用
メモリＲＯＭをキーに内蔵し電源投入と同時に几〇へ４
に記・１妃された設定を実行できるよつＫＬ、たコンピ
ュータの電源スィッチを提供することにある。That is, the purpose of the present invention is to eliminate the above-mentioned drawbacks by incorporating a read-only memory ROM in the key that stores information to be set after the power is turned on, and switching to ㇠〇 at the same time as the power is turned on.
The object of the present invention is to provide a power switch for a computer that can carry out the settings described in Section 1.
本発明のコンピュータの電源スィッチは、電源投入後に
設定すべき情報を記憶した読出専用メモリを内蔵すると
ともに挿入部分に前記読出専用メモリを制御するための
几ＯＭ制ヲ１１端子を有するキーと、前記キーが完全に
挿入されたときに前記ＲＯＭ制御端子と接触する電極を
有する電源スィッチと連動する錠を含んで構成される。The power switch for a computer according to the present invention includes a built-in read-only memory storing information to be set after the power is turned on, and a key having an OM control terminal 11 in an inserted portion for controlling the read-only memory; The lock includes a lock interlocked with a power switch having an electrode that contacts the ROM control terminal when the key is fully inserted.
次に、本発明の実施例について、図面を用いて詳細に説
明する。Next, embodiments of the present invention will be described in detail using the drawings.
第１図は本発明の一実施例を示す斜視図であり、１０は
キー、２０は読出専用メモリ、３０はＲＯＭ制御端子、
４０は錠、５０はＲＯＭ制御線電極、６０は電源スィッ
チ、７０は電源線である。FIG. 1 is a perspective view showing an embodiment of the present invention, in which 10 is a key, 20 is a read-only memory, 30 is a ROM control terminal,
40 is a lock, 50 is a ROM control line electrode, 60 is a power switch, and 70 is a power line.
キー１０は、読出専用メモリ２０を内蔵しておシ、ＲＯ
Ｍ制御端子３０を除く部分は、絶縁物で覆われている。The key 10 has a built-in read-only memory 20.
The portions other than the M control terminal 30 are covered with an insulator.
また、錠４０は、キー１０が完全に錠穴に挿入されたと
きに、はじめて回転可能となシ、その時ＲＯＭ制御端子
３０はＲＯＭ制御線電極５０と接触している。Further, the lock 40 can only be rotated when the key 10 is completely inserted into the lock hole, at which time the ROM control terminal 30 is in contact with the ROM control line electrode 50.
この状態でキー１０を回転させると、電源スィッチ６０
が回転し、電源線７０が接続される。When the key 10 is rotated in this state, the power switch 60
rotates, and the power line 70 is connected.
電源投入により、コンピュータは起動し、ＲＯＭ制御線
電極５０、およびＲＯＭ制御端子３０を通して、読出専
用メモリ２０の内容を読み取り、必要とする設定が自動
的に行なわれる。When the power is turned on, the computer starts up, reads the contents of the read-only memory 20 through the ROM control line electrode 50 and the ROM control terminal 30, and automatically makes necessary settings.
次に、このようなコンピュータの電源スィッチの一応用
例を以下に説明する。Next, an application example of such a power switch for a computer will be described below.
一例として、キー１０内の読出専用メモリ２０に使用者
の識別コードＩＤと、起動すべきプログラムが記憶され
ているとする。As an example, assume that the read-only memory 20 in the key 10 stores a user's identification code ID and a program to be started.
第１図に示すような、コンピュータの電源スィッチを使
用することによシ、電源投入以外に伺の動作も行なわず
、目的のプログラムを起動することができる。By using the computer's power switch as shown in FIG. 1, it is possible to start a desired program without performing any other operation other than turning on the power.
また、識別コードＩＤが情報として入っているため、使
用者の集計をコンピュータに行なわせることが可能とな
る。Furthermore, since the identification code ID is included as information, it is possible to have the computer perform a tally of users.
また、プログラムリストの出力を許可するかどうかの情
報を読出専用メモ９２０に記憶しておき、特定の人以外
は、プログラムリストを出力できないようにし、プログ
ラムの外部流出を防止することも可能となる。In addition, information on whether to permit output of the program list is stored in the read-only memo 920, so that only a specific person can output the program list, thereby making it possible to prevent programs from being leaked outside. .
