Disk device having disk transferring mechanism capable of shortening disk replacement time

A disk device comprising:

• one insertion/ejection slot for inserting or ejecting a disk;
• and
• a driving unit ascended or descended in a direction crossing at a right angle with a disk surface of the disk inserted in the insertion/ejection slot to drive the disk while clamping it thereon,
• wherein a first driving position and a second driving position where the disk is driven are set at different positions along the ascending or descending direction of the driving unit;
• wherein a transferring means is provided with a distributing mechanism for selectively changing over a transferring direction of the disk inserted into the insertion/ejection slot to either the first driving position or the second driving position, and transfers the disk distributed by the distributing mechanism to the first driving position or the second driving position, the distributing mechanism having a distributing member supported to pivot up and down in order to guide the disk inserted into the insertion/ejection slot diagonally upward or diagonally downward;
• and
• wherein, when a next disk is inserted into the insertion/ejection slot under a state in which the preceding disk is present at one of the first driving position and the second driving position, the next disk inserted is distributed and transferred to the other driving position where the preceding disk is not present by the distributing member, the disk already present is ejected out of the insertion/ejection slot, and the next disk is driven by the driving unit in the other driving position.
