Abstract
A floppy disk assembly is adapted to accommodate a floppy disk having a discrimination hole for discriminating a storage capacity and includes a detecting member, a cassette holding plate, a sliding plate, a lock member, and a rod member. The detecting member detects whether or not the discrimination hole is present. The sliding plate has a projection and is subjected to a spring action for causing the cassette holding plate to slide from a position at which the floppy disk is mounted/dismounted to a position at which writing/reading is performed by a magnetic head. The lock member engages or disengages with the projection on the sliding plate when the floppy disk is dismounted or mounted. A rod member is linked to one end of the lock member and is allowed to rotate as the floppy disk abuts the rod member upon the mounting of the floppy disk. The use of the rod member makes it possible to move the location of the lock member beyond the location of the hole detection member.
