PURPOSE: A computer is provided to automatically open/close a drive door when a tray installed to a disk drive is withdrawn/inserted and to reduce noise when the drive door is opened/closed. CONSTITUTION: The drive door(40) rotationally opens/closes an opening part(30). A spring device pulls the drive door to an opposite direction of opening rotation while the drive door rotates to a state of a predetermined angle from a closed state. While the drive door rotates to a full-open state from the state opened to the predetermined angle, the spring device pushes the drive door to an opening rotation direction. The spring device includes a contact projection(45) rotating with the drive door and a leaf spring(50).
