Problems solved by technology

[0003] In this case, the drive device for the floppy disk is configured with the floppy disk insertion port and the light-emitting diode on the front side of the drive device for the floppy disk. The back side on the drive device, therefore need to carry out the integrated circuit module (IC) that the floppy disk drive device is used for drive control and also be arranged on the back side side on the floppy disk drive device, this must make the gap between the light emitting diode and the integrated circuit module The distance is relatively long, and the connecting conductor part for connecting them is also relatively long

Abstract

The invention provides a floppy disc driving device which is provided with a circuit substrate mounted on one side of a chassis on which at least an integrated circuit and an interface connector are mounted, a light emitting diode located near a diskette insertion slot that emits light when a floppy disc is rotatively driven, and a connection conductor that connects between the circuit substrate and the light emitting diode, wherein the connection conductor is the membrane conductor formed by spreading coating material on one side of the chassis, and wherein the light emitting diode is driven with a current supplied from the integrated circuit through the membrane conductor.

Description

technical field [0001] The present invention relates to a drive device (FDD) for a floppy disk, in particular to a drive circuit for a light emitting diode (LED) which is arranged at a position near a floppy disk insertion port and can generate light beams when the floppy disk is rotationally driven, and can control the light emitting diode. A floppy disk drive (FDD) that can drive reliably and reduce the cost of the drive circuit. Background technique [0002] Generally speaking, conventional floppy disk drive devices are equipped with light emitting diodes near the floppy disk insertion opening. When the floppy disk is driven to rotate, the light emitting diodes are ignited to display the state of the floppy disk. [0003] In this case, the drive device for the floppy disk is configured with the floppy disk insertion port and the light-emitting diode on the front side of the drive device for the floppy disk. The back side on the drive device, therefore need to carry out t...
