Abstract
A controlling unit of a library device scans a home position and each stop position by driving a picker unit upward and downward, and controls the position of the picker unit using an average value of two position data. Additionally, the controlling unit measures an entire stroke of a hand unit attached to the picker unit, and corrects the stop position of the hand unit using a ratio of an actually measured value to a design value.
