<P>PROBLEM TO BE SOLVED: To solve the problem that even only allocation of a pass gate requires a big initial investment in a place wherein an infrastructure is absent. <P>SOLUTION: From the viewpoint that a person can pass a gate only when the gate is open, by acquiring information, only during a open state of the gate, from a user terminal 8 or an information storage medium 3 of a user 2 getting on and off a mobile body 7 by passage through the gate that is an entrance of the mobile body 7, a function of the pass gate 1 is secured without using the pass gate 1 used as a starting point of some system heretofore. That is, the gate provided as the entrance of the mobile body 7 can bear a part as an input device acquiring information about the user 2 passing over some boundary, e.g. information about 'which user 2 passes over the boundary, what boundary the user 2 passes over and when the user 2 passes over the boundary' by the gate passage as if the gate is the input device previously mounted in each stop place, only during a gate opening state wherein the mobile body 7 stops and wherein a door is opened. <P>COPYRIGHT: (C)2004,JPO |
