<p>PURPOSE:To prevent the double issuance of a ticket and the omission of it from occurring due to the error of information transmission by performing a ticket issuance management by a ticket number by a host computer and a reserved ticket issuance terminal. CONSTITUTION:The terminal side communication control part 21 of the reserved ticket issuance terminal 2 performs on line communication with the host computer 1 via a communication line 3, and also, the ticket issuance printer 22 of the terminal 2 prints a ticket. The printed ticket number table 23 of the terminal 2 stores a printed ticket number, and the ticket issuance data buffer 24 of the terminal 2 stores ticket issuance data transiently until the printer 22 completes the print of the ticket issuance data when receiving the ticket issuance data. In such a way, since the ticket issuance management by the ticket number is performed by both the computer 1 and the terminal 2, the next ticket issuance data for which an operation is restarted at a host side can be recognized even when a fault occurs in a ticket issuance printer. In such a way, it is possible to prevent the double issuance of the ticket and the omission of it from occurring due to the error.</p> |
