PURPOSE:To realize the system at a low cost by putting recognition numbers which begin with a different number and end in a different number at every kind to a use ticket, and also, recognizing the final recognition number of the use ticket issued to its organization at every prescribed organization, and setting its next number as a first number of the next discrimination reference range. CONSTITUTION:A first number and a final number of recognition numbers are determined in advance at every kind of use tickets, and also, at every prescribed ticket issue period, a final recognition number of a ticket issued in its period is checked in each separate kind, so that at the time of examining a ticket in the next period, the recognition number of the use ticket brought by a user exists between the next number of the final recognition number of the previous game and the final number determined in advance or not is discriminated. Accordingly, it will suffice that a manager of facilities only transfers the final recognition number of each separate kind of tickets issued on that day to a ticket examining place 4 from a ticket vending place 1 or a management office 3, etc., for instance, every day by some means. In such a way, the use ticket can be discriminated without using a large scale computer system, etc., especially. The system can be realized at a low cost. |
