Claims

[Scope of utility model registration request]

In a floppy disk device that uses a floppy disk in which a circular disk medium is housed in a square jacket as a storage medium, the floppy disk device includes a reflective portion provided at a predetermined portion of the jacket, and a casing of the floppy disk device. a light emitting element attached to a part of the body and projecting light toward the floppy disk; and a first light receiving element attached to a part of the casing and receiving the projected light from the light emitting element via the reflective part of the jacket. an insertion operation in which a second light-receiving element is attached to a part of the housing and directly receives the projected light from the light-emitting element, and output signals from at least the first and second light-receiving elements are input. A floppy disk device comprising: a discriminator.
