PROBLEM TO BE SOLVED: To easily find out unfairness by a method wherein at lest two control units which are connected so as to communicate with each other and the direction of communication between both the units is regulated in one direction by a regulating means, and the presence of abnormality is judged and the abnormality through a second control unit based on the judgment. SOLUTION: In a switch job which is performed by a main control unit 140 for controlling a game, various signals such as a shoot stop sensing signal, a touch sensing signal, a count sensing signal, a special region passage sensing signal, etc., are taken into the unit 140 through a relay substrate 123, Whereupon, at first, it is judged whether or not an abnormality has occurred in a count sensing switch 86 or a count sensing and special region passage sensing switch 87, and if an abnormality has occurred, an error job is performed. That is, if an abnormality has occurred in winning balls, a report command is sent to a special pattern control unit 160 from the unit 140 to display only a symbol such as a numeral, e.g. '8', on the display screen of a special pattern display device, thereby reporting the abnormality. |
