<P>PROBLEM TO BE SOLVED: To surely detect the existence of a preceding disk in the case where a subsequent disk is continuously pushed in during preceding disk eject processing. <P>SOLUTION: In the case where double insertion prevention processing is started within a drive unit, a nonvolatile memory stores therein information that two disks have been inserted and eject processing of a subsequent disk D' is executed. At such a time, when the subsequent disk D' is ejected, it is referenced whether or not two disks have been inserted from the stored information. When the subsequent disk is inserted, it is possible for a preceding disk D to be left inside the drive unit, so that an operation for ejecting the left disk D is performed by operating a feed roller. The presence/absence of the disk D is then confirmed by a photosensor. In the case where it is confirmed that the preceding disk D is not left, the feed roller is returned to a standby position and the operation is finished. If the disk D exists, ejecting work is performed again. <P>COPYRIGHT: (C)2013,JPO&INPIT |
