Abstract
Abstract To display picking information on a liquid crystal display unit, ID tags are disposed at the entrance and the exits of paths between racks, and the current position of a picking cart is recognized by way of communication with an antenna. Between an entrance and an exit, the distance over which the picking cart has traveled from the communication position with an ID tag is detected by way of an encoder which detects rotation of a wheel of the picking cart to recognize the current position.
