Title: Cancellation system for seats reservation
Inventor: KOYAMA KAZUHIRO
IPC: G06Q50/00
Filed: 1990-05-11
Abstract: PURPOSE:To enable the new reservation of a corresponding seat and to efficiently use the seats of a train by checking the content of the ticket of a customer on board and cancelling the reserved seat. CONSTITUTION:A device 4 for issuing a train ticket prints and outputs the ticket so that the reserved train and seat can read at least by a ticket reading device 5. A train reservation part 5a of the ticket reading device 5 designates the train which the customer takes. The ticket reading device 5 transfers information read out from the ticket at the time of seat detection and the information of the name of the train designated by the train reservation part 5a to a central processing unit 1. The central processing unit 1 compares these, and cancels the seat written in the ticket when they are different. Thus, even when taking the train other than the reserved one, the seat is cancelled automatically so that the cancelled seats can be used efficiently.
