PROBLEM TO BE SOLVED: To recognize a carrier slip-off prevention shaft by a method wherein the carrier slip-off prevention shaft is formed for fixing a plurality of discs by inserting into a transparent hole in a front face plate of a disc accmmodation rack when the disc accommodation rack is pulled out of an enclosure of an autochanger, and a storing insertion hole for storing the carrier slip-off prevention shaft is provided at a corner part with which discs in the disc accommodation rack do not come into contact. SOLUTION: A disc accommodation rack 3 bas a disc accommodation part 11 comprising a plurality of partition plates 11a, 11b between a front face plate 11F and a rear face plate 11B. A carrier slip-off prevention shaft 17 is inserted into transparent holes 11Fa, 11Ba punched in the front face plate 11F and the rear face plate 11B, to retain discs. There are provided storing insertion holes 21F, 21B for storing the carrier slip-off prevention shaft 17 at a corner at a rear lower end of the disc accommodation part 11. Thus, it is possible to store the carrier slip-off prevention shaft 17 at a corner uninfluenced in discs accommodation of the disc accommodation rack 3a, and immediately recognize the carrier slip-off prevention shaft 17.
