【発明の詳細な説明】
〔産業上の利用分野〕
本発明は、情報処理装置の電源供給に関し、特に停電時
において再立ち上げに必要な情報を退避させる為の電力
補償に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a power supply for an information processing device, and particularly to power compensation for saving information necessary for restarting the device in the event of a power outage.

〔発明が解決しようとする課題〕
しかしながら、上述した従来の方式では、停電時にしか
使われない物理的に大きく、しかも高価なハードウェア
を必要とし、また常時無駄な電力を消費するという欠点
がある。Conventionally, power compensation for information processing equipment during a power outage has been performed using a method that uses power stored in advance using a large battery or the inertia of a flywheel. [Problems to be Solved by the Invention] However, the above-mentioned conventional This method requires physically large and expensive hardware that is only used during power outages, and has the disadvantage of constantly consuming unnecessary power.

な最低限の処理を行う手段とを有している。The information processing device of the present invention includes a means for extracting electric power from a drive motor of a built-in or connected magnetic disk device, and a minimum processing necessary for restarting the power supply port 1 during summer using the electric power. and the means to do so.
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り、情
報処理装置本体系１と、電源２と、コンバータ３と、磁
気ディスク装置４０〜４ｎとから構成されている。FIG. 1 is a block diagram showing an embodiment of the present invention, which is composed of an information processing apparatus main body system 1, a power supply 2, a converter 3, and magnetic disk drives 40 to 4n.
通常、電源２から本体系１と磁気ディスク装置４０〜４
ｎへ電源が供給されている。Normally, from the power supply 2 to the main body system 1 and the magnetic disk devices 40 to 4
Power is being supplied to n.
次に、電源２に供給されているＡＣ電源が途絶えると、
電源２から本体系１とコンバータ３へ非常信号２３が送
出され、コンバータ３が磁気ディスク装置４０〜４ｎの
駆動用電動機Ｍから得られる電力を本体系１に送るとと
もに、本体系１はＡＣ電源回復時に再立ち上げする為に
必要なデータの退避を行う。Next, when the AC power supplied to power supply 2 is interrupted,
An emergency signal 23 is sent from the power supply 2 to the main system 1 and the converter 3, and the converter 3 sends the power obtained from the drive motor M of the magnetic disk devices 40 to 4n to the main system 1, and the main system 1 recovers the AC power. Back up the data necessary to restart the system.
以上説明したように本発明は、停電時に磁気ディスク装
