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: a gaming ball detection channel through which a gaming ball passes; a pair of magnetic field generation means for generating a magnetic field in the gaming ball detection channel, the pair of magnetic generation means being arranged around the gaming ball detection channel so as to face each other; yokes forming an annular magnetic path between the pair of magnetic field generation means, the yokes being arranged around the gaming ball detection channel; and magnetic flux detection means for detecting a change in magnetic flux generating in the annular magnetic path.

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:    a gaming ball detection channel through which a gaming ball passes;    a pair of magnetic field generation means for generating a magnetic field in said gaming ball detection channel, the pair of magnetic generation means being arranged around the gaming ball detection channel so as to face each other;    yokes forming an annular magnetic path between said pair of magnetic field generation means, the yokes being arranged around said gaming ball detection channel; and    magnetic flux detection means for detecting a change in magnetic flux generating in said annular magnetic path.    
   
   
       2 . The gaming machine according to  claim 1 , 
 said yokes comprising:    a first yoke having a space and formed on said annular magnetic path; and    a second yoke arranged facing the first yoke,    wherein    said magnetic flux detection means is arranged within said space.    
   
   
       3 . The gaming machine according to  claim 2 , 
 wherein    said magnetic field generation means face each other in a direction parallel to a board face of said gaming board,    said yokes are arranged along the direction, and    said magnetic flux detection means is arranged such that a detection face for detecting the change in magnetic flux is perpendicular to the board face of said gaming board.    
   
   
       4 . The gaming machine according to  claim 1 , 
 wherein    said magnetic flux detection means comprises a Hall element.
