A gate apparatus is provided a convey path enabling an IC card (ID information storage medium) to be inserted and discharged from either of a front side and a rear side of the gate apparatus and, therefore, entering/exiting can be monitored by the single gate apparatus. A CPU determines the direction of discharge of the IC card on the basis of detection results of a card sensor and a door state detecting means. Thus, entering/exiting information can exactly be understood.
