PURPOSE:To make it possible to recognize a point of time, when cancel processing is performed, later when the return processing of a ledger file is performed by generating any fault in a line between a host and a betting machine. CONSTITUTION:The host receives a request from the betting machine (100) and judges whether the request is a betting request or a cancel request (200) and when it is the betting request, the betting request is registered on the ledger file (400). Continuously, the serial number of the host is counted up (400) and a betting response set that counted-up serial number is transmitted to the betting machine (500). On the other hand, when the received request is the cancel request, the cancel processing of the ledger file is performed (700), namely, the serial number of the host is compared with a serial number set to that request and when the difference is '1', the betting request of that serial number is canceled from the ledger file. Then, the serial number of the host is counted up, and a cancel response set this counted-up serial number is transmitted to the betting machine. |
