イデイスク。[Scope of Claim for Utility Model Registration] (1) A floppy disk that is detachable from a disk recorder and is used to record information or reproduce recorded information by being attached to the disk recorder; a cassette housing for rotatably housing the disc-shaped recording medium; a head insertion hole formed in at least one of the upper and lower surfaces of the cassette housing; the disc-shaped recording medium and the head; a plate-shaped member provided between the head insertion hole and the surface of the cassette housing and rotatably supported; a plate-shaped member formed in the plate-shaped member and having a size approximately corresponding to at least the head insertion hole; a guide hole that is formed in the surface of the cassette housing where the insertion hole is formed and is elongated in the circumferential direction; and a guide hole that is formed to protrude on the surface of the plate-like member and that is formed in the guide hole. An engaging protrusion is provided for engaging with the hole to restrict movement of the plate-like member, and when the engaging protrusion is on one end side in the circumferential direction of the guide hole, the head is inserted by the plate-like member. The head insertion hole is opened by shielding the hole and the head insertion hole and the defective portion facing each other when the engagement protrusion is on the other end side in the circumferential direction of the guide hole. A floppy disk. (2) The length of the guide hole is selected to be greater than or equal to the width of the head insertion hole.
The floppy disk described in (1). (3) The floppy disk according to claim 1, wherein the length of the guide hole is selected to be at least twice the width of the head insertion hole. (4) The floppy disk according to any one of claims (1) to (3) for utility model registration, wherein the plate-shaped member is disc-shaped. (5) The floppy disk according to claim 4, wherein the defective portion is an opening formed in the disc-shaped plate member. (6) The floppy disk according to claim 4, wherein the defective portion is a V-shaped or U-shaped notch formed in the radial direction of the disk-shaped recording medium. (7) The plate-like member has a semicircular shape, and the missing portion is a portion of the plate-like member other than the semicircular portion of the disk shape, which is also used as a portion of the plate-like member, Claim No. (1) The floppy disc according to any one of paragraphs ) to (3). (8) The plate-shaped member is fan-shaped, and the missing portion is a portion of the plate-shaped member excluding the sector-shaped portion from the disc shape. The floppy disk described in any of paragraph (3). (9) The head insertion hole and the guide hole are
Utility model registration claim 1, which is formed on both upper and lower surfaces of the cassette housing, and the plate-like member is provided on both upper and lower surfaces of the disk-shaped recording medium.
The floppy disc described in any of paragraphs (1) to (8).
