Abstract
A library apparatus includes an accessor robot and a flat cable connected to the accessor robot. The flat cable has an outer check line and an inner check line each formed of a conductor. Breaks in each of the outer check line and the inner check line are detected to identify wear on the flat cable, and prevent sudden failure of the library apparatus.
