<p>PROBLEM TO BE SOLVED: To detect winning abnormality in a variable winning device set to a start winning hole, and to output an error signal to a hall computer when detecting the winning abnormality.SOLUTION: When a start pocket solenoid is in a non-operation state, left and right movable pieces are raised up such that a game ball cannot enter a second start pocket. Conversely, when the start pocket solenoid is in an operation state, upper end sides are enlarged and opened horizontally with lower end sides as axes in the left and right movable pieces such that a game ball can enter the second start pocket. A main control MPU determines the presence or absence of abnormality in the number of winning game balls to the second start pocket, based on a detection signal of a second start pocket sensor and preset winning permission conditions, and outputs an error signal from an external terminal board to the hall computer when it is determined that the number of winning balls is abnormal.</p> |
