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 a change in amount of light emitted from a light emitting element and received by a light receiving element to thereby detect passage of the gaming ball through the predetermined region; and second detection means for detecting a change in galvanomagnetic effect caused by an element placed in a static magnetic field generated by magnetic field generation means to thereby detect passage of the gaming ball through the predetermined region.

Claims

exact text as granted — not AI-modified
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 a change in amount of light emitted from a light emitting element and received by a light receiving element to thereby detect passage of the gaming ball through said predetermined region; and    second detection means for detecting a change in galvanomagnetic effect caused by an element placed in a static magnetic field generated by magnetic field generation means to thereby detect passage of the gaming ball through said predetermined region.    
   
   
       2 . The gaming machine according to  claim 1 , 
 wherein    said gaming ball detection device comprises a metal plate inside the device, said metal plate being provided at a place where a magnetic flux generated by said magnetic field generation means flows to said element that causes the galvanomagnetic effect.    
   
   
       3 . The gaming machine according to  claim 1 , 
 wherein    said element that causes the galvanomagnetic effect is a Hall element.    
   
   
       4 . The gaming machine according to  claim 1 , 
 wherein    said element that causes the galvanomagnetic effect is a magnetoresistive element.
