PROBLEM TO BE SOLVED: To detect illegality in a counter with simple configuration without providing a detecting sensor by providing a hall computer for comparing an integrated ball number of a corrected ball number with a counting signal from a ball number counter, judging illegality when the number of balls expressed by means of the counting signal is larger and judging a normality in a case except it. ;SOLUTION: The hall computer 6 integrates a replenishing signal and an out ball signal inputted from a PACHINKO (Japanese pin ball game) machine 2 and a ball lending signal inputted from a ball lending machine 3 corresponding to the PACHINKO machine 2 and also integrates the previously planned corrected ball number so as to integrate the integrated ball number. But, an out ball signal is integrated as a minus(-) since discharge is executed from the PACHINKO machine 2 to a discharge gutter. When the counting signal is inputted, the counted ball number being a winning ball number expressed by the counting signal which is inputted from the ball number counter 4 is compared with the integrated ball number, illegality is judged when the counted ball number expressed by the counting signal is larger than the integrated ball number and the normality is judged in the case except it.;COPYRIGHT: (C)1999,JPO
