Abstract: To assuredly determine whether a shutter pinches a disk in a disk device including a shutter at a disk insertion slot. A shutter control device 10 includes a pinch determining unit 14 that determines whether the disk is pinched by the shutter based on a position of the shutter during a process of closing the shutter, and a sensitivity changing unit that sets sensitivity of determination to be high as ambient temperature of a shutter driving mechanism increases.

Abstract: During a process of closing of a shutter of a disk device, a position of the shutter is detected. A first shutter position indicator indicative of a first position of the shutter and a second shutter position indicator indicative of a second position, which is immediately before the first position, are calculated. Whether a disk is pinched by the shutter is determined based on comparison of a predetermined threshold and the difference between the first shutter position indicator and the second shutter position indicator.

Abstract: A controller 27 controls the driving member 2 to move the conveyer 23 as a second member to a target position of the receiving rack 10 as a first member in the other direction after moving the conveyer 23 over the target position when the conveyer 23 is moved in one direction to align the conveyer 23 with the target position. After the conveyer 23 is moved over the target position and when the conveyer 23 is moved in the other direction, the controller controls the conveyer 23 to move by a distance of a mechanical error at a time, and then to move intermittently to the target position for aligning the conveyer 23 with the target position.
