PURPOSE: To shorten a face adjustment processing time by making a user customer notice the generation of boarding fare shortage, permitting the charging of a fare adjustment card based on the input operation of a fare adjustment input part and fare-adjustment-processing by subtracting a shortage amount from the fare-adjustment card.

CONSTITUTION: When a reading means 24 detects boarding fare shortage and regulating passing at the exiting of a user customer who gets a train excessively, an annunciating means 18 annunciates the shortage of a boarding fare to the customer based on it. Then, when the annunciated customer input-operates a fare adjustment input part 16 to adjust the fare, a fare adjustment control means 21 permits the charging of a fare adjustment card while interlocking with it, fare-adjustment-processes a differential amount from the fare adjustment card charged by the customer and permits passing. Thus, the fare-adjustment processing can be executed without a fare adjustment window and a fare adjuster only by add-charging the fare adjustment card at exiting of the customer who gets the train excessively and the fare adjustment processing at exiting can be executed efficiently and rapidly by using the combination of a boarding ticket and the card.
