PROBLEM TO BE SOLVED: To provide visual effect as if the probability of hitting bonanza is changing by making the displaying figure of 'effective line' alterable. SOLUTION: The first counter referring part 14 extracts counted values of the first counter 13 in every 30 seconds then informs the values to the referring value specifying part of an effective line 15 and specifies an effective line number responding to the counted value and a referring value of a bonanza. When a bonanza detecting part 24 detects a bonanza, a comparing part 27 compares the value of the second counter 16 and each referring value of the bonanza. And in the case where both the values are in accordance with each other, the part 27 informs 'accordance' information to a pattern selecting part 17 and a bonanza judging part 20. The value of a line counter 19 and an effective line number are compared, and when they are in accordance with, the second opening and closing part 25 is directed to open an open-close plate. The pattern selecting part specifies, by using the 'accordance' information, the bonanza pattern matching to the value of the line counter 19 and inform the same to an image controlling part 18. The denotation of specifying the effective line is displayed in a displaying area corresponding to the effective number. |
