PROBLEM TO BE SOLVED: To prevent the breakage of components during force insertion of a disk. SOLUTION: The disk transportation mechanism includes an ejecting arm 52 which is pressed by the disk 2 during insertion of the disk 2 and is rotationally moved within a casing 3, and presses the disk 2 to eject the disk to the outside of the casing 3 when ejecting the disk 2, a biasing means 56 which biases the ejecting arm 52 in the ejecting direction of the disk 2, a driving mechanism 120 of rotationally moving the ejecting arm 52 toward the ejecting direction of the disk 2, a linkage mechanism which connects the ejecting arm 52 and the linkage mechanism, and a guide cam mechanism which has a cam means for insertion of guiding the linkage mechanism so as to suppress the biasing force of the biasing means 56 and a cam means for ejection. The guide cam mechanism assures the movable region of the linkage mechanism when the disk 2 is inserted into a retraction region of the casing 3. COPYRIGHT: (C)2008,JPO&INPIT
