Control methods and media processing apparatus of media transport mechanism

摘要

A media transportation mechanism control method and a media processing device can accurately detect the last disc or other media stored in a media storage unit. A transportation arm 36 is lowered to the media stacker 21, the transportation arm 36 is paused when the media detection mechanism 200 detects the media, and the transportation arm 36 is then raised and the position where the media detection mechanism 200 stops detecting the media is stored as media height H. After the transportation arm 36 descends again, picks a disc M from the media stacker 21, and then rises, the media height H is compared with a prescribed threshold limit α. If the media height H is less than the threshold limit α, the number of media left in the media stacker 21 is determined to be a prescribed count (such as zero).
