Abstract

PURPOSE:To discriminate the ready/loading state of a floppy disk drive and to improve the operability of the floppy disk drive by controlling current quantity to be supplied to one lamp according to the information of the first circuit to detect the ready state and the information of the second circuit to detect the loading state. CONSTITUTION:While the ready state of a circuit is detected, and a ready signal 1 is outputted by a ready state detecting circuit 101 for the floppy disk drive, the loading state is detected, and a loading signal 2 is outputted by a head state control circuit 201. The light quantity of a lamp 4 is adjusted by a lamp light quantity control circuit 3, to which these ready signal 1 and loading signal 2 are inputted, based on the information of the inputted ready signal 1 and the information of the inputted loading signal 2, and the ready/loading state is displayed. Further, it becomes possible to discriminate the ready/loading state with one lamp, and the floppy disk drive can be miniaturized without damaging the operability of the floppy disk drive.

Description

【発明の詳細な説明】 〔産業上の利用分野〕 本発明はフロッピィディスクドライブに関する。[Detailed description of the invention] [Industrial application field] The present invention relates to floppy disk drives.

〔従来の技術〕[Conventional technology]

従来のフロッピィディスクドライブには、レディ状態を
表示するランプと、ロード中を表示するランプとが別々
についている構造となっているか、レディ状態を表示す
