PROBLEM TO BE SOLVED: To make it possible to continue to accurately issue pass tickets without issuing any wrong ticket if a vehicle detector misdetects one vehicle as two vehicles. SOLUTION: The number of the shafts of vehicles detected by an entering vehicle detector 1 and a starting vehicle detector 6 are detected by an entry-side step plate 2 and a starting-side step plate 7. When the number A of the shafts detected by the starting-side step plate 7 for the first time after a pass ticket regarding a ticket issue object vehicle is taken out is larger than the number of the shafts detected by the entry-side step plate 2 as to the ticket issue object vehicle, a control part 83 controls a ticket issue part 81 by a wrong ticket countermeasure process means 83b so that a pass ticket issued next by the ticket issue part 81 is recovered once the start of the vehicle is detected. Further, when the number B of the shafts is less than the number A of the shaft, the ticket issue part 81 issues a pass ticket in response to the detection of a next vehicle by the starting vehicle detector 6. |
