Abstract: A carrying section of a disk apparatus includes a pair of arms disposed in a substantially symmetrical relationship with respect to the carrying direction of a disk in the proximity of the opposite ends of an opening formed in a housing such that the arms pivot around end portions thereof adjacent the opening in synchronism with each other in directions toward and away from each other, and a biasing element which biases the arms in a direction in which ends of the arms remote from the opening approach each other. The arms individually have rollers provided thereon which grip and carry the disk to a predetermined position. At least one of the rollers is rotated by the driving member to carry the disk.
