したことを特徴とする情報処理装置の電源回路。[Claim for Utility Model Registration] In a power supply circuit of an information processing device having a drive storage device that chucks and holds the center of a rotating recording medium and drives it to rotate, turning on a main power switch connected in series to a power supply section is provided. A first detecting means for detecting, a first switch that is turned on in conjunction with the detecting operation of the first detecting means, and a first switch that is interlocked with a member such as a lever that is driven during the chuck operation of the rotating recording medium. a second switch, an internal battery connected in series to the first switch and the second switch, and a second detection means for detecting the on state of both the first and second switches; a third switch connected in parallel with the main power switch that is activated and turned on by the detection operation of the second detection means, and the rotating recording medium is accessed when the main power switch is turned on. A power supply circuit for an information processing device, characterized in that when the main power switch is turned off, a third switch is automatically turned on so that power continues to be supplied even if the main power switch is turned off.
