PURPOSE: To report it to a user as quickly as possible in the case of an invalid card with which he cannot pass by closing a door at the time when a human being detection means detects the user and a detection means detects a shading material and a transmitter doesn't communicate. CONSTITUTION: The user entering a ticket examination passage p is detected by a human being detector S1 on the entrance side, and a card C is detected by shading material detector A. In this state, data is smoothly communicated between the card C and an automatic ticket examination machine G, and when entrance/exit is permitted as the result of operation processing, a door 1 is opened, and the automatic ticket examination processing of the card C is performed. If data is not smoothly communicated between the card C and the automatic ticket examination machine G though the shading material detector A detects the shading state of the card C, or the card C is judged to be invalid, the door 1 is closed and a lamp L1 is lit to inform the user and a clerk that passage of the user is stopped. |
