Claims (1)

[Claims for Utility Model Registration] A tray that is formed with a bracket on which a pinion gear is arranged and a rack that meshes with the pinion gear, and that moves horizontally to move forward and backward with respect to the bracket as the pinion gear rotates. and a support for the tray so as to move integrally with the tray when the tray moves horizontally, and to move vertically independently of the tray when the tray is retracted into the bracket. A cassette mounting device comprising: a holder for holding a cassette; and a cover for covering the rack.
