Patent attributes
A media cartridge autoloader is disclosed which includes a main module including a media cartridge picker that pulls in a media cartridge via a mail slot and ejects the media cartridge via the mail slot. A media drive selectively receives the media cartridge. First and second media cartridge transport magazines transportably store the media cartridge. The main module further includes a stopper mechanism that inhibits the media cartridge from being fully reinserted when inserting the media cartridge is attempted in a state where the media cartridge has been ejected so as to at least partially protrude outside of the mail slot. The stopper mechanism contacts a lower part of a rear side of the media cartridge to stop the media cartridge in a state where a front side of the media cartridge is at least partially ejected through the mail slot.
