ピーデイスクドライブユニツト。 A base plate that accepts a floppy disk on the top surface,
A magnetic head carriage is provided with a magnetic head for recording and reproducing data on and from the received floppy disk, and is provided on the base plate so as to be able to reciprocate in one direction, and when the magnetic head carriage reciprocates, the received floppy disk is read and recorded. a floppy disk drive having a position detector provided on the base plate for detecting a retraction limit position of the magnetic head carriage; and a cover attached to the base plate so as to cover the magnetic head carriage and the position detector. In the disk drive unit,
The magnetic head carriage has an arm extending outward from the magnetic head carriage, and the position detector includes support pieces that face each other with a gap between which the arm is interposed when the magnetic head carriage is at the retraction limit position; It is characterized by comprising a light source and a light receiver installed in opposing surfaces with a gap between both support pieces, and the gap between the support pieces is installed in such a manner that it does not open facing the cover. A floppy disk drive unit.
