Gaming machine
View Patent ↗A gaming machine includes a gaming table, antennas and a control unit. The antennas are arranged to placement areas formed on the gaming table. The antennas are employed to determine whether or not at least one gaming medium is placed on any of the placement areas. The control unit drives at least two antennas simultaneously so that a direction of magnetic field generated by one antenna is opposed to one generated by at least one other antenna adjacent to the one antenna.
1. A gaming machine comprising:
a gaming table on which placement areas are formed, wherein at least one gaming medium to which identification information is assigned is placed on any of the placement areas;
detecting units that are arranged to the placement areas and employed to determine whether or not the at least one gaming medium is placed on any of the placement areas;
and a control unit that drives each of the detecting units to generate a radio wave from a detecting unit, which is one of the detecting units, in a direction for passing through a placement area to which the detecting unit is arranged, so as to read identification information assigned to at least one gaming medium placed on the placement area and carry out the determination,
wherein
the detecting units are arranged in a matrix state with columns and rows,
the control unit simultaneously drives at least two detecting units, which are part of the detecting units, positioned on a line of column, so that a polar character of radio wave generated by one detecting unit, which is part of the at least two detecting units, is opposed to one generated by at least one other detecting unit, which is part of the at least two detecting units, adjacent to the one detecting unit, and the control unit reads identification information assigned to one or more gaming media which are part of the at least one gaming medium, and generates column data including the identification information,
the control unit simultaneously drives at least two detecting units, which are part of the detecting units, positioned on a row crossing the line of column, so that a polar character of radio wave generated by one detecting unit, which is part of the at least two detecting units, is opposed to one generated by at least one other detecting unit, which is part of the at least two detecting units, adjacent to the one detecting unit, and the control unit reads identification information assigned to one or more gaming media which are part of the at least one gaming medium, and generates row data including the identification information, and the control unit carries out a logical AND operation with respect to the column and row data to determine whether or not one or more gaming media which are part of the at least one gaming medium, are placed on a placement area corresponding to an intersection of the lines of column and row.
2. The gaming machine according to claim 1 , wherein the polar character of radio wave is a direction of magnetic field.
3. The gaming machine according to claim 1 , wherein the control unit simultaneously drives at least two sets of at least two detecting units which are part of the detecting units, so that a polar character of radio wave generated by one detecting unit, which is part of the at least two detecting units, is opposed to one generated by at least one other detecting unit, which is part of the at least two detecting units, adjacent to the one detecting unit in each set.
