ABSTRACT:
A problem that carriage of a disk by a feed roller cannot be smoothly accomplished depending on a type of the disk is to be solved. To achieve the object, the feed roller has an overall shape of expanding in diameter, and has floating roller parts movably fitted to a roller shaft in a central part and fixed roller parts pressed in and fixed in its two sides. A rotational force transmitted from a disk carrying motor causes a downward force to work on the feed roller through a roller gear. Even when a pressing force on the disk weakens, the fixed roller parts on the two sides can serve to carry the disk smoothly.
