Gaming machine

Abstract

The present invention provides a gaming machine comprising a gaming ball detection device for detecting a gaming ball having passed through a predetermined region of a gaming member provided on a gaming board, wherein the gaming ball detection device comprises: first detection means for detecting that a gaming ball passing through the predetermined region is within a first detection range; and second detection means for detecting that a gaming ball passing through the predetermined region is within a second detection range different from the first detection range, and one detection range of the first detection range or the second detection range is included in the other detection range.

1 . A gaming machine comprising a gaming ball detection device for detecting a gaming ball having passed through a predetermined region of a gaming member provided on a gaming board, 
 wherein    said gaming ball detection device comprises:    first detection means for detecting that a gaming ball passing through said predetermined region is within a first detection range; and    second detection means for detecting that a gaming ball passing through said predetermined region is within a second detection range different from said first detection range, and    one detection range of said first detection range or said second detection range is included in the other detection range.    
   
   
       2 . The gaming machine according to  claim 1 , 
 wherein    a physical quantity measured when said first detection means detects the gaming ball and a physical quantity measured when said second detection means detects the gaming ball are of different kinds.    
   
   
       3 . The gaming machine according to  claim 2 , 
 wherein    said first detection means comprises a photo sensor for measuring a change in amount of light emitted from a light emitting element and received by a light receiving element to thereby detect the gaming ball passing through said predetermined region; and    said second detection means comprises a magnetic sensor for measuring a change in a magnetic field generated by a magnetic field generation means to thereby detect the gaming ball passing through said predetermined region.    
   
   
       4 . The gaming machine according to  claim 3 , 
 wherein    said photo sensor and said magnetic sensor are disposed along a moving direction of the gaming ball, and    said photo sensor is located between said magnetic field generation means and said magnetic sensor.
