<p><P>PROBLEM TO BE SOLVED: To provide a parlor managing system which can determine the number of visitors to the game parlors with a higher precision. <P>SOLUTION: The total of the number of balls brought into the machines by the customers specified by the setting of the membership cards or others and the number of the customers involved to obtain the average number of balls brought per the specified customer. The total number of the balls brought into the machines as a whole in the game parlors is determined including the unspecifiable customers who have played games without the setting of the membership cards and is divided by the average number of the balls brought into the machines to derive the estimated number of visitors. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
