Abstract

PURPOSE:To prevent the destruction of recording contents of a floppy disk by making a mechanism capable of closing a front lever only when a power is supplied to the floppy disk device and then the floppy disk is inserted. CONSTITUTION:The supply or cut-off state of the power for the floppy disk device is confirmed by a power supply detecting circuit 1 with a power signal 101. When the power for the floppy disk device is cut off, the front lever is locked by a front lever lock opening and closing part 2. Then, only when the power is supplied and then the floppy disk is inserted, the opening and closing part 2 is released from its lock, and hence the front lever can be closed. By this method, the destruction of the recording contents of the floppy disk can be prevented.

Description

【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、コンピュータシステムにおける周辺入出力装
置の一つであるフロッピィディスク装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a floppy disk device, which is one of the peripheral input/output devices in a computer system.

る欠点がある。In the above-mentioned conventional floppy disk device, regardless of whether the power is turned on or off, if the floppy disk is inserted into the disk drive and the front lever is closed, the floppy disk is fixed and the head is brought into contact with the recording medium of the floppy disk at the same time. Therefore, if the floppy disk is inserted first and the power is turned on, the recorded contents of the floppy disk may be destroyed and the floppy disk may become unusable.

を有することにより構成される。The floppy disk device of the present invention is a floppy disk device in which the floppy disk is fixed by closing a front lever and the head is brought into contact with the recording medium. It is configured by having a front lever opening/closing part that unlocks the front lever when inserted.

〔実施例〕〔Example〕

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

ている。FIG. 1 is a block diagram of an embodiment of the present invention. This floppy disk device includes a power-on detection circuit 1 that confirms whether the floppy disk device is powered on or off using a power signal 101, and a power-on detection signal 102 that is the output of the power-on detection circuit 1. It has a front lever lock opening/closing part 2 that can open and close the front lever in response to a floppy disk insertion detection signal 103.

でも機械的にロックが解除できるようにしである。In the above configuration, when the power to the floppy disk device is turned off, the front lever is locked by the front lever lock opening/closing part 2, but the front lever is locked only when the power is turned on and a floppy disk is inserted. The opening/closing part 2 is unlocked and the front lever can be closed. Since it is necessary to insert a head protection sheet and close the front lever during transportation, a separate, inconspicuous switch is installed so that the lock can be mechanically released even when the power is turned off.
