<P>PROBLEM TO BE SOLVED: To provide a game machine that can suppress detection errors of injected game balls. <P>SOLUTION: The machine is configured to detect passing of game balls by arranging upstream sensors 553, 2553 and downstream sensors 554, 2554 in a passage and in a part in which flowing direction of game balls varies. Consequently, even when a plurality of game balls flow in a chained state (in a manner stringing together), a condition can be formed in which neither the upstream sensors 553, 2553 nor the downstream sensors 554, 2554 detect game balls. As a result, detection error is suppressed in which game balls flowing down in a stringing manner are mistakenly recognized as one game ball, thereby ensuring detection of the injected game balls. <P>COPYRIGHT: (C)2013,JPO&INPIT |
