PROBLEM TO BE SOLVED: To display state such as wire breaking, a fault or the like of a switch for detecting passing of playing balls to a start mouth, before the start of special pattern fluctuation is started. SOLUTION: When interruption to a checking timer occurs two times of more, it is judged whether a combined-use switch is off or not (S304). If the switch is off, the interruption times of the checking timer is judged whether the interruption are made seven times or more (S305). If the interruption times are less than seven, a special pattern is fluctuated and a switch passing flag gets 1 to be set (S307). Meanwhile, in the Step 304, if the off-state of the combined-use switch is continued, the checking timer is set to +1 (S309), and interruption times of the checking timer is judged whether they are 100 or not (S310). If the interruption reaches 100, an abnormal flag gets 1 to be set (S311). A display CPU 62 displays an S-error on a special pattern display device 23 (S313). |
