     BACKGROUND OF THE INVENTION  
      1. Field of the Invention  
      The present invention relates to a gaming machine, and more specifically, it relates to a gaming machine determining a result of a game based on a fact that a lottery ball enters to a lottery hole in the lottery wheel.  
      2. Description of the Related Art  
      Hitherto, a bingo game is played by using a bingo card having squares aligned in a matrix form. In this case, different indicias are assigned to the squares, and the square corresponding to the indicia won by a lottery is punched. You can win by punching squares aligned in one vertical, horizontal or diagonal line.  
      While a bingo card made of paper is generally used in a bingo game, various electronically controlled gaming machines (see JP-A-2001-161888, for example) imitating the game have been developed. Such a gaming machine displays a bingo card on a display device thereof, and, when an indicia won by a lottery exists on the bingo card, the box is activated to display so that the activated box can be distinguished from the other boxes. Generally, a lottery wheel has a plurality of lottery holes having indicia, and, when a lottery ball stops at one of the lottery holes, a square corresponding to the indicia where the lottery ball stops is activated. The gaming machine is often placed in a game arcade since many game players can participate therein.  
      In order to further increase the amusingness of a game, various attempts are being made in developing this kind of gaming machine, such as moving a part of a gaming machine to dynamically change a condition for a lottery ball to stop at a lottery hole for variety of the game and/or decorating a gaming machine itself based on a theme defined for the game.  
      By the way, in a game arcade where the gaming machine is placed, many machines such as gaming machines and a money changer are closely provided. A player uses equipment such as a cellular phone and audio and video apparatus. Thus, the gaming machine is required not to prevent normal operations of the other equipment. Especially, an amount of radiant noise, which is electromagnetic waves, generated by the gaming machine must be kept equal to or lower than a predetermined standard such that electromagnetic interference (EMI) can be prevented. Besides, Class A that is applied to the one to use in the industrial area (Section 5 of Electrical Appliance and Material Safety Law) is given as the example of “the predetermined standard”. For a gaming machine to be provided in a game arcade, their own regulations are defined in addition to the legal EMI regulations.  
      However, a gaming machine to be provided in a game arcade is larger in size and weight than a home gaming machine as well as various apparatus included in the gaming machine. Furthermore, since the various apparatus are driven by high voltage and large current, the amount of radiant noise generated by the gaming machine may easily increase. Especially, when a part or all of the body of the gaming machine is operated, the spatial distribution of the radiant noise varies with time. Thus, the radiant noise must be lower than an acceptable amount even in any state that the gaming machine can be placed, and a sufficient margin must be allowed for a predetermined acceptable limit.  
     SUMMARY OF THE INVENTION  
      An object of the invention is to provide a gaming machine, which can increase amusingness of a game and suppress the generation of radiant noise.  
      More specifically, the invention provides the following gaming machine.  
      According to a first aspect of the invention there is provided a gaming machine including: a cabinet frame; a non-conductive cabinet internally having the cabinet frame; a rocking frame oscillatably supporting the cabinet; an rocking device for oscillating the cabinet; an attachment base fixed to the cabinet frame, at least one substantially entire surface of which is a ground plane; a lottery wheel disposed above the attachment base and having a plurality of lottery holes to which lottery balls enter; a discharge device that is provided below the lottery wheel and that discharges the lottery balls entering, one each, the plural lottery holes; a control substrate electrically connected to the ground plane for detecting that a lottery ball enters to the lottery hole.  
      Further, according to a second aspect of the invention there is provided a gaming machine including: a cabinet frame; a cabinet internally having the cabinet frame; a rocking frame oscillatably supporting the cabinet; an rocking device for oscillating the cabinet; an attachment base fixed to the cabinet frame, at least one substantially entire surface of which is a ground plane; a lottery wheel disposed above the attachment base and having a plurality of lottery holes to which lottery balls enter; a detector attached to the attachment base for detecting that a lottery ball enters to the lottery hole; and a strut extending upward from the position of the lottery wheel and electrically connecting to the cabinet frame and the ground plane.  
      According to the first and the second aspect of the invention, substantially all of one surface of the attachment base fixed to the cabinet frame within the cabinet is a ground plane, and the cabinet frame and strut are electrically connected thereto. The attachment base to which the detector is attached and the strut extending upward are grounded so that the radiant noise generated by the gaming machine can be suppressed. Furthermore, the strut and the lottery wheel rock in response to the rocking of the cabinet so that the rocking of the cabinet can be visually emphasized. Therefore, the generated radiant noise can be suppressed, and the presence can be enhanced by the rocking of the cabinet, which can increase the amusingness of a game.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS  
      An example of embodiments of the invention will be described with reference to drawings.  
      While a gaming machine  310  of this embodiment is a gaming machine to be played by using a game medium such as a card storing information on a game value given to or to be given to a game player as well as a coin, medal, lottery ball or token, a medal is used in the description below.  
      Configuration of Gaming Machine  
       FIG. 1  is a perspective view showing a schematic appearance of a gaming machine in this embodiment.  
      The gaming machine  310  includes a lottery machine  312  and a plurality of gaming terminals  314 . The gaming machine  310  can simultaneously provide a game to a plurality of game players through the plurality of gaming terminals  314 A to  314 J.  
      The lottery machine  312  mainly includes a cabinet  313  having a form imitating a ship and is placed at the center of the gaming machine  310 . Furthermore, two lottery wheels  338  and  339  are placed at the center of the lottery machine  312 . These two lottery wheels  338  and  339  have 52 lottery holes  340  and  341  in total (see  FIG. 4 ). These plural lottery holes  340  and  341  are associated with indicias, which are combinations of first signs including spades, clubs, hearts and diamonds, and second signs including numbers from 2 to 10 and letters A, J, Q and K. The indicia is used for determining a lottery result. In other words, indicias for determining lottery results are associated with the plurality of lottery holes  340  and  341  in the lottery wheels  338  and  339 , respectively A lottery is performed in accordance with one of the plurality of lottery holes  340  and  341  to which a lottery ball enters, and the game result is determined. Two struts  354 A and  354 B compared to masts of a ship extend upward from the respective centers of the lottery wheels  338  and  339 . Metallic horizontal bars  355 A to  355 H are attached to the struts  354 A and  354 B, respectively, substantially orthogonally to each other with metallic latches so as to become parts of the masts of the ship, which are decorations of the lottery machine. An rocking device  346  (see  FIG. 2 ) including a motor is placed in the lottery machine  312  so that the cabinet  313  can be rocked to move a stem  312 A and a stern  312 B vertically. In other words, the rocking device  346  rocks the cabinet  313 . Notably, the incline has an angle of about 8 degree vertically with respect to the horizontal plane in this embodiment but is not limited thereto. Furthermore, while the oscillating operation takes about 12 seconds from the state that the stem  312 A is positioned above at an angle of about 8 degree with respect to the horizontal plane to the state that the stem  312 A is positioned below at an angle of about 8 degrees with respect to the horizontal plane, the time is not limited thereto. Preferably, the oscillating operation takes about 8 seconds to about 16 seconds. More specifically, the cycle of the rocking can be controlled by a main control circuit  400 , which will be described later, and may be defined to be adjustable by, for example, a manager of the game arcade. Furthermore, since the ship-shaped cabinet  313  is used, which can be rocked, in this embodiment, a visual effect can be given to game players, which can therefore enhance the amusingness.  
      A plurality of gaming terminals  314 A to  314 J are placed on both sides of the lottery machine  312 . In this embodiment, 10 gaming terminals  314  to  314 J are provided. The plurality of gaming terminals  314 A to  314 J have medal payout ports  382 A to  382 J.  FIG. 1  does not show the gaming terminals  314 F to  314 H and medal payout ports  382 F to  382 J, which are hidden by the lottery machine  312 .  
      While, in this embodiment, the ten gaming terminals  314 A to  314 J are provided as the plurality of gaming terminals, the invention is not limited thereto, but other forms may be adopted. For example, different gaming terminals rather than ten gaming terminals may be provided or one gaming terminal may be provided.  
      Configuration of Lottery Machine  
       FIG. 2  is a longitudinal sectional view showing a schematic appearance of the lottery machine  312  in this embodiment.  
      The lottery machine  312  includes the cabinet  313  made of a synthetic resin and in imitation of the hull of a ship and a metallic cabinet frame  351  internally supporting the cabinet. A supporting piece  351 A extends downwards from the substantial center of the cabinet frame  351 , and the supporting piece  351 A has a rocking axis  348 . The cabinet  313  and cabinet frame  351  are oscillatably supported by a rocking frame  359  about the rocking axis  348 . In this case, the rocking frame  359  is a base of the lottery machine. The rocking device  364  is provided in the rocking frame  359  of the lottery machine  312  and moves the supporting piece  351 A. Thus, the cabinet  313  can be inclined about the rocking axis  348 .  
      An attachment base  352  made of wood is fixed and mounted on the cabinet frame  351 . The attachment base  352  is used for mounting a controller for controlling different devices of the lottery machine  312 . A control circuit substrate  353 , which will be described later as one of controllers, is mounted on the attachment base  352 .  
      As an example of an lifting device, a screw conveyer  320  is placed in the stern  312 B of the lottery machine  312 . The screw conveyer  320  is an apparatus for conveying a lottery ball used for a lottery upward with respect to the lottery wheels  338  and  339  through the internal part of the lottery machine  312 . While the lottery ball in this embodiment has a diameter of about 60 mm, other forms may be adopted therefor. For example, the lottery ball may have a diameter equal to, larger than or smaller than about 60 mm. Furthermore, the lottery ball is preferably made of a material not allowing infrared ray to pass through or is preferably processed so as not to allow infrared ray to pass through such that the lottery ball can be easily detected by different kinds of sensors such as an optical sensor.  
      The screw conveyer  320  includes a spiral body  320 A, a supporting plate  320 B and a lottery ball lifting motor  320 C. The spiral body  320 A extends upward from a conveyance start position  320 D at a predetermined angle of inclination. The supporting plate  320 B extends along the spiral body  320 A. The lottery ball lifting motor  320 C rotates the spiral body  320 A. The spiral body  320 A has a helical groove having a radius of curvature larger than a radius of the lottery ball. Driving the lottery ball lifting motor  320 C rotates the spiral body  320 A, and a lottery ball is conveyed to the upper part with the lottery ball retained between the helical groove in the spiral body  320 A and the supporting plate  320 B. The screw conveyer  320  conveys the lottery ball  302  to be conveyed in a manner that the lottery ball  302  can be visually checked.  
      One end of a lottery ball guide portion  324  is provided at the upper end of the screw conveyer  320 . The lottery ball guide portion  324  has a guide path (not shown). The lottery ball guide portion  324  guides a lottery ball conveyed by the screw conveyer  320  through the guide path.  
      A lottery ball holding portion  332  is provided in the upper part of the lottery machine  312 . The lottery ball holding portion  332  stands on the cabinet  313  and is supported by the struts  354 A and  354 B extending upward from the center position of the lottery wheel. The lottery ball holding portion  332  is made of a transparent resin such that game players and so on can visually check. Thus, the number of remaining lottery balls can be clearly shown to game players. The lottery ball holding portion  332  opens upward in form and holds lottery balls having been guided thereto from the lottery ball guide portion  324 . The bottom of the lottery ball holding portion  332  has an opening (not shown) for allowing one lottery ball to pass through.  
      A rotary body  328  is provided below the lottery ball holding portion  332 . The rotary body  328  is cylindrical and is an example of a dropping portion. The rotary body  328  has a function of closing the opening in the bottom surface of the lottery ball holding portion  332 . Thus, the state that a lottery ball is held in the lottery ball holding portion  332  can be maintained.  
      The rotary body  328  has a holding hole (not shown) for holding one lottery ball. A drive portion (not shown) including a rotation motor  326  (see  FIG. 10 ) is provided at the edge of the rotary body  328 . Driving the drive portion rotates the rotary body  328 . Rotating the rotary body  328  opens the holding hole to the above so that one lottery ball held in the lottery ball holding portion  332  can be dropped to the holding hole through the opening. Furthermore, rotating the rotary body  328  closes the opening in the lottery ball holding portion  332  and holds one lottery ball in the holding hole. Furthermore, rotating the rotary body  328  closes the opening in the lottery ball holding portion  332  and opens the holding hole to the bottom so that one lottery ball held in the holding hole can be dropped downward. Thus, one lottery ball held in the lottery ball holding portion  332  can be extracted and dropped downward. In other words, the rotary body  328  has a function of dropping a lottery ball having been conveyed by the screw conveyer  320  from the upper part to plane portions  338 A and  339 A. The rotary body  328  is made of a transparent resin such that a lottery ball held in the holding hole can be visually checked by game players. Thus, the developments of a game can be clearly shown to game players.  
      A transparent lottery ball receiving portion  334  is provided below the rotary body  328 . The lottery ball receiving portion  334  receives a lottery ball dropped from the holding hole of the rotary body thereabove. Thus, a lottery ball having been dropped from the holding hole of the rotary body  328  is held in the lottery ball receiving portion  334  with the lottery ball visually checkable by game players. The lottery ball receiving portion  334  has notches  334 C and  334 D (see  FIG. 4 ) through which a received lottery ball can be dropped to one of the lottery wheels  338  and  339 . Since the lottery machine  312  has a function of oscillating, a lottery ball held in the lottery ball receiving portion  334  is guided to one of the two lottery wheels  338  and  339  in accordance with the angle of inclination thereof.  
      Slopes  336 A and  336 B having inrut paths allowing lottery balls to pass through are provided to the notches  334 C and  334 D (see  FIG. 4 ) of the lottery ball receiving portion  334 . These slopes  336 A and  336 B are used for dropping a lottery ball held in the lottery ball receiving portion  334  to one of the lottery wheels  338  and  339 . The slopes  336 A and  336 B are made of a transparent resin. Thus, lottery balls passing through the slopes  336 A and  336 B can be visually checked by game players. In this way, the above-described screw conveyer  320 , rotary body  328 , slopes  336 A and  336 B and so on can drop lottery balls having been discharged from the plurality of lottery holes  340  and  341  to the lottery wheels  338  and  339  through a collection path  350  as described later.  
      The metallic struts  354 A and  354 B supporting the lottery ball holding portion  332  are connected to a ground plane  356  (see  FIG. 3 ) on the surface of the ground plane  356  of the attachment base  352  through conductors  358 A and  358 B, respectively.  
      The two lottery wheels  338  and  339  are placed at the lower ends of the slopes  336 A and  336 B. These lottery wheels  338  and  339  have plane portions  338 A and  339 A, respectively, having surfaces horizontal to the cabinet  313 . Lottery balls can roll on the plane portions  338 A and  339 A. In other words, the lottery wheels  338  and  339  have plane portions  338 A and  339 A, respectively, on which lottery balls can roll and have the plurality of lottery holes  340  and  341  in the upper surface of the plane portions  338 A and  339 A. Furthermore, these two lottery wheels  338  and  339  can rotate horizontally with respect to the upper surfaces of the plane portions  338 A and  339 A.  
      The upper surfaces of these plane portions  338 A and  339 A have the plurality of lottery holes  340  and  341  each for holding one lottery ball. These plural lottery holes  340  and  341  are deep enough for one lottery ball to project about 2/5. Thus, lottery balls having entered to these plural lottery holes  340  and  341  are held in a manner that game players can visually check the lottery balls. Furthermore, subsequently dropped lottery balls come into collision with the lottery balls held in the plurality of lottery holes  340  and  341  and change the direction of rolling. As described later, the lottery balls having entered to the lottery holes  340  and  341  move in response to rotations of lottery wheels  338  and  339  with the lottery balls held in the lottery holes  340  and  341  until the end of one game.  
      Open/close shutter s  344  ( 344 A and  344 B) ( FIG. 7 ) are provided below the lottery wheels  338  and  339  at positions through which the lottery holes  340  and  341  pass in response to the rotation of the lottery wheels  338  and  339 . While a game is being played, the open/close shutter s  344 A and  344 B are controlled to close, and the lottery wheels  338  and  339  hold lottery balls in the lottery holes  340  and  341 . After the game ends, the open/close shutter s  344 A and  344 B are controlled to open, and the lottery balls in the plurality of lottery holes  340  and  341  are discharged through an discharge path  347  ( FIG. 7 ) and collection path  350  disposed below the lottery wheels  338  and  339 .  
      As shown in  FIG. 7 , ball entrance detection sensors  349  (ball entrance detection sensors  349 A and  349 B in  FIG. 7 ) are provided in the lottery holes  340  and  341 . Each of the ball entrance detection sensors  349  detects that a lottery ball enters to one of the plurality of lottery holes. On the condition that a lottery ball enters to one of the plurality of lottery holes  340  and  341  in the lottery wheels  338  and  339 , indicia is selected in accordance with the lottery hole to which the lottery ball has entered, and a game result thereof is determined based on the selected indicia. In other words, on the condition that a lottery ball has entered to one of the plurality of lottery holes  340  and  341 , the game result is determined based on the indicia associated with one of the plurality of lottery holes  340  and  341  to which the lottery ball has entered. While, in this embodiment, one ball entrance detection sensor  349  is provided in each of the plurality of lottery holes  340  and  341 , other forms may be adopted. For example, a plurality of ball entrance detection sensors may be provided for each of plural lottery holes such that the fact that a lottery ball has entered thereto can be immediately detected. Furthermore, in order to reduce works in a producing process therefor and to reduce costs, an ball entrance detection sensor may not be provided in each of the plurality of lottery holes. In other words, two ball entrance detection sensors may be used to detect that lottery balls have entered to plural lottery holes. For example, a fixed sensor may be provided below a lottery wheel so that a lottery hole to which a lottery ball has entered can be located based on a rotating position of the lottery wheel when the lottery wheel rotates and the sensor detects that the lottery ball passes.  
      The collection path  350  is provided under the lottery wheels  338  and  339 . An discharged lottery ball drops down into the collection path  350 . The collection path  350  extends to the conveyance start position of the lifting device, and a lottery ball rolls within the collection path  350  by being guided toward the conveyance start position.  
      The lottery machine  312  rocks such that the stern  312 B side can be lower than the stem  312 A side. Thus, a lottery ball held in the collection path  350  is guided to the lower end of the spiral body  320 A.  
      A dot LED display device  327  is provided above the lottery ball holding portion  332 . The dot LED display device  327  includes a plurality of LEDs. The dot LED display device  327  displays a round number in a game. A START lamp  329  is provided at the center of the lottery machine  312 . The START lamp  329  contains a lamp lighting up when a lottery ball drops down from the holding hole of the rotary body  328  to the lottery ball receiving portion  334 . In response to the lighting-up of the contained lamp, the word, START, is displayed so that game players can visually check it. Furthemore, the gaming machine  310  includes a plurality of illumination apparatus (not shown) so that the ship-shaped lottery machine  312  can be lighted up in various colors and various effects can be given in response to rocking operations.  
      Cabinet Frame and Attachment Base  
       FIG. 3  is a partial sectional view showing the cabinet frame  351  and attachment base  352  within the cabinet  313 . The cabinet frame  351  includes a plurality of metallic tubes aligned in parallel. Since each of the tubes in the cabinet frame  351  has a square section, the tubes have an upper surface being flat. The attachment base  352  made of wood is fixed on the cabinet frame  351  with bolts. A conductive film made of aluminum foil is adhered onto the substantially entire surface of the attachment base  352  and serves as the ground plane  356  on the attachment base  352 . The adhesion of aluminum foil can eliminate the necessity of the attachment base  352  made of a conductive material, which can increase flexibility in material selection. In this embodiment, the attachment base  352  made of wood can be light-weight and be readily machined.  
      The attachment base  352  is fixed from the upper part of the ground plane  356  to the cabinet frame  351  with metallic bolts, and the cabinet frame  351  is electrically connected to the ground plane  356  made of aluminum foil. Various control substrates such as the control circuit substrate  353  are attached onto the ground plane  356  of the attachment base  352 . The grounds of the substrates are connected to the ground plane  356 . Furthermore, some of the substrates are covered with a shield case  357  and then are attached onto the attachment base  352 . In this case, since the shield case  357  is directly in contact with the ground plane  356 , both of them are electrically connected. The control circuit substrate  353  functions as a detector for detecting that a lottery ball enters to a lottery hole.  
      The attachment base  352  is placed widely within the cabinet  313  so that the internal part of the cabinet  313  can be horizontally divided into two ( FIG. 2 ). Since the substantially entire surface on the attachment base  352  is the ground plane  356 , a horizontally wide ground plane is provided within the cabinet, and this is grounded to the cabinet frame. Thus, radiant noise generated by the gaming machine  310  can be suppressed. Furthermore, since the internal part of the cabinet  313  is horizontally divided into two by the ground plane  356 , the amount of radiant noise generated by the motor of the rocking device  346  under the ground plane  356  and reaching to the control substrates such as the control circuit substrate  353  above the rocking device  346  can be reduced.  
      The conductor  358 A connecting to the strut  354 A ( FIG. 2 ) is connected to the ground plane  356  of the attachment base  352 . The conductor  358 B, not shown in  FIG. 3 , connecting to the strut  354 B ( FIG. 2 ) is also connected to the ground plane  356  like the conductor  358 A. Thus, the struts  354 A and  354 B are electrically connected to the ground plane  356  of the attachment base  352 . Furthermore, since the struts  354 A and  354 B are electrically connected to the horizontal bars  355 A to  355 D and  355 E to  355 H, respectively, the struts  354 A and  354 B and horizontal bars  355 A to  355 H are all grounded. A motor for controlling movement of a lottery ball in the lottery ball holding portion  332  is adjacent to illumination lamps in the vicinity of the struts  354 A and  354 B. Thus, radiant noise generated by a change in current fed thereto may be diffused by using the metallic struts  354 A and  354 B and horizontal bars  355 A to  355 H as antennas. However, the diffusion of radiant noise can be suppressed by grounding the struts  354 A and  354 B and horizontal bars  355 A to  355 H. Thus, the radiant noise generated by the gaming machine can be suppressed by grounding the struts  354 A and  354 B. The struts  354 A and  354 B rock in response to the rocking of the cabinet  313  along with the lottery wheels  338  and  339  so that the rocking of the cabinet  313  can be visually emphasized. Therefore, the generated radiant noise can be suppressed, and presence can be enhanced by the rocking of the cabinet, which can increase amusingness of the game.  
      The ground plane  356  of the attachment base  352  is electrically connected to the rocking frame  359  through the cabinet frame  351 , supporting piece  351 A and rocking axis  348 . Furthermore, the rocking frame  359  is electrically connected to the motor cabinet of the rocking device  346 . Since all of them are therefore grounded, the generation of radiant noise can be suppressed.  
      Besides, contents of a test of a radiated noise are shown below.  
      An allowable value with noise power is equal to or less than 55 dB in 30 MHz-300 MHz.  
      An allowable value with noise voltage among the terminals is equal to or less than 56 dB in 526.5 kHz-30 MHz, and equal to or less than 60 dB in 5 MHz-30 MHz.  
      Lottery Ball Receiving Portion  
       FIG. 4  is a top view showing the lottery receiving portion  334  and slopes  336 A and  336 B. The lottery ball receiving portion  334  has a recessed portion  334 A The recessed portion  334 A receives lottery balls dropping from the holding holes of the rotary body  328 . A side  334 B of the lottery ball receiving portion  334  has two notches  334 C and  334 D. Thus, the lottery ball received by the recessed portion  334 A rolls from one of the two notches  334 C and  334 D to the outside of the recessed portion  334 A in response to the rocking of the lottery machine  312 .  
      The upper ends of the slopes  336 A and  336 B are connected to these notches  334 C and  334 D. Furthermore, the lower ends of the slopes  336 A and  336 B are placed above the lottery wheels  338  and  339 , respectively, as described above. Thus, these slopes  336 A and  336 B receive lottery balls rolled from the notches  334 C and  334 D of the above-described lottery ball receiving portion  334  to the outside of the lottery ball receiving portion  334  and are then guided to one of the lottery wheels  338  and  339 . Each of these slopes  336 A and  336 B is placed such that lottery balls can be dropped in the same direction as the direction of rotation of each of the lottery wheels  338  and  339 . While, in this embodiment, the slope  336 A and  336  have a straight form, they do not have to have a straight form but may have a curve, for example.  
      Lottery Wheels  
       FIG. 5  is a top view showing the lottery machine  312  and lottery wheels  338  and  339 . Since the lottery wheel  339  has a similar configuration to that of the lottery wheel  338 , the description will be omitted herein. As shown in  FIG. 5 , the lottery machine  312  includes the two lottery wheels  338  and  339  as described above. Since the two lottery wheels  338  and  339  can have the plurality of lottery holes  340  and  341 , the installed space in a place of amusingness can be used more effectively without requiring a wasteful space required for many lottery holes than the space having one lottery wheel, for example. Thus, the lottery wheels can have many lottery holes, which can increase amusingness such as providing a variety of dividends.  
      The lottery wheels  338  and  339  are circular in the top view. These lottery wheels  338  and  339  are rotatably provided at positions on the deck of the cabinet  313  having a form in imitation of a ship. The standard rotational speed of the lottery wheel  338  is a speed at which one rotation takes 8 to 12 seconds but can be controlled by a main control circuit  400 , which will be described later. For example, the rotational speed can be adjusted in the range of 5 to 12 seconds per rotation. While, in this embodiment, the lottery wheels  338  and  339  are pivoted by lottery wheel rotation motors  335  and  337  (see  FIG. 10 ) positioned at the respective center thereof, other forms can be adopted. For example, power for rotation can be conducted from other parts such as outer peripheries and bottom surfaces thereof. The lottery wheels  338  and  339  have the plane portions  338 A and  339 A, which allows rolling of lottery balls. Furthermore, the lottery wheels  338  and  339  rotate in the same directions (see arrows B 1  and B 2 ) as the directions (see arrows A 1  and A 2 ) in which lottery balls are dropped from the slopes  336 A and  336 B. More specifically, the lottery wheel  338  rotates clockwise, and the slope  336 A is disposed in the clockwise direction as shown in  FIG. 5 . Thus, when lottery balls roll on the lottery wheels  338  and  339 , the speed does not rapidly decrease. Therefore, the possibility is low that a lottery ball enters to one of the plurality of lottery holes  340  and  341  in an extremely short period of time. Furthermore, the rotation of the lottery wheels  338  and  339  allows lotteries to be performed without any change in speed of lottery balls sequentially dropped from the slopes  336 A and  336 B. When the lottery wheels  338  and  339  do not rotate, that is, the positions of the lottery holes  340  and  341  are not changed, an uneven game can be achieved in which a lottery ball dropped at a predetermined speed can easily or hardly enter a specific one of the plurality of lottery holes  340  and  341 . The rotation of the lottery wheels  338  and  339  can prevent uneven lotteries.  
      A connection table  390  is provided between the two lottery wheels  338  and  339 . The connection table  390  has a surface horizontal to the plane portions  338 A and  339 A of the lottery wheels  338  and  339 . Thus, a lottery ball can roll between the lottery wheels  338  and  339 . Furthermore, in response to the inclining (rocking) of the cabinet  313 , a lottery ball rolls across the plurality of lottery wheels  338  and  339 .  
      Guide portions  392  and  394  are provided between the lottery wheels  338  and  339 . These guide portions  392  and  394  are provided at positions sandwiching the connection table  390  along the outer peripheries of the lottery wheels  338  and  339 . These guide portions  392  and  394  are higher than the plane portions  338 A and  339 A of the lottery wheels  338  and  339  and have a convex fore. Lottery balls come into collision with the guide portion  392  and  394  so that the orbits of the lottery balls can be guided.  
      Bank portions  396  and  398  are provided outside the lottery wheels  338  and  339 . These bank portions  396  and  398  are provided along the outer peripheries of the lottery wheels  338  and  339 . These bank portions  396  and  398  are higher than the plane portions  338 A and  339 A of the lottery wheels  338  and  339  and have a convex form. In other words, the bank portions  396  and  398  higher than the top surface of the plane portions  338 A and  339 A are provided along the outer peripheries of these plane portions  338 A and  339 A. Thus, even when lottery balls dropped from the slopes  336 A and  336 B to the lottery wheels  338  and  339  roll to the outside of the lottery wheels  338  and  339 , the lottery balls ran onto the bank portions  396  and  398  and roll on the lottery wheels  338  and  339  again. Furthermore, since the orbits of lottery balls returning from the bank portions  396  and  398  are changed by momentum and/or directions of the lottery balls running onto the bank portions  396  and  398 , an unpredictable game can be provided to game players, which can enhance amusingness of the game. Furthermore, when lottery balls having run onto the bank portions  396  and  398  roll on the lottery wheels  338  and  339 , the speed does not significantly decrease. Thus, when the lottery balls having run onto the bank portions  396  and  398  roll onto the lottery wheels  338  and  339 , the speed does not significantly decrease. Therefore, the possibility is low that a lottery ball enters to one of the plurality of lottery holes  340  and  341  in an extremely short period of time, and a lottery ball enters to one of the plurality of lottery holes  340  and  341  in about 10 to 30 seconds.  
      Furthermore, the lottery wheels  338  and  339  rotate in the opposite directions as indicated by the arrows B 1  and B 2 . Thus, lottery balls having dropped to the lottery wheel  338  roll from the lottery wheel  338  to the lottery wheel  339  through the connection table  390 . Conversely, lottery balls having dropped to the lottery wheel  339  rolls from the lottery wheel  339  to the lottery wheel  338  through the connection table  390 . Thus, lottery balls roll between the lottery wheels  338  and  339 . Furthermore, since the rocking device  346  is provided in the lottery machine  312 , the cabinet  313  of the lottery machine  312  is rocked thereby. Then, for example, lottery balls are rolled in infinity orbit between the lottery wheels  338  and  339 . Thus, an unpredictable and innovative game can be provided to game players, which can enhance amusingness of the game. Notably, the lottery wheels  338  and  339 , connection table  390 , guide portions  392  and  394  and bank portions  396  and  398  are enclosed by a fence made of a transparent resin so that no lottery balls can roll to the outside of the fence.  
      These lottery wheels  338  and  339  have  26  lottery holes  340  and  26  lottery holes  341 , respectively. As shown in  FIG. 6 , indicias including spades and hearts as first signs are assigned to the plurality of lottery holes  340  in the lottery wheel  338 . More specifically, A,  2  to  10 , J, Q and K of spades and A,  2  to  10 , J, Q and K of hearts are assigned to the plurality of lottery holes  340  in the lottery wheel  338 . On the other hand, indicias including clubs and diamonds as first signs are assigned to the plurality of lottery holes  341  in the lottery wheel  339 . More specifically, A,  2  to  10 , J, Q and X of clubs and A,  2  to  10 , J, Q and K of diamonds are assigned to the plurality of lottery holes  341  in the lottery wheel  339 . In other words, a position where a lottery ball is rolling is visually checked for matching some of the plurality of signs so that the indicia desired by a game player can be easily recognized. Thus, haste and expectations of the game player can be more raised and amusingness of the game can be enhanced. For example, while a lottery ball is rolling on the lottery ball  338 , the fact that the first sign is spades or hearts can be easily recognized. While a lottery ball is rolling on the lottery ball  339 , the fact that the first sign is clubs or diamonds can be easily recognized. In other words, on the two lottery wheels  338  and  339 , indicias some of first signs of which match are assigned to the plurality of lottery holes  340  and  341  in the two lottery wheels  338  and  339 . Thus, a position where a lottery ball is rolling is visually checked for matching some of the plurality of signs so that the indicia desired by a game player can be easily recognized. Therefore, haste and expectations can be more raised and amusingness of the game can be enhanced.  
      Open/Close Shutter and Collection Path  
       FIG. 7  is a sectional view showing a configuration in which the open/close shutter  344 A, which is a disk having two notches, is provided by being joined to the axis of rotation of the motor  345 . In order to show a movement of a lottery ball, the sectional view shows a section along the outer circumference having lottery holes of the lottery wheels  338 .  
      While the lottery wheel  338  is provided above the cabinet  313 , a part of the cabinet  313  under the lottery wheel  338  has a circular hole  313 A, and the open/close shutter  344 A is provided in the hole. When a draw is being made, the open/close shutter  344 A is closed. A lottery ball having dropped to a lottery hole is supported by the cabinet  313  and open/close shutter  344 A so as to be retained not to fall any further. Once the game ends and the open/close shutter  344 A is rotationally driven by  90  degrees by the motor  345 , the two notches of the open/close shutter  344 A are positioned under the outer circumference and inner circumference having lottery holes (the state shown in  FIG. 7 ). When the lottery wheel  338  rotates under this state, a lottery ball having passed above the open/close shutter  344 A further passes through the notches of the open/close shutter  344 A and falls to the discharge path  347 A. Thus, the lottery balls retained in the plurality of lottery holes  340  of the lottery wheel  338  are all discharged from the discharge path  347 A as a result of one rotation of the lottery wheel  338 . Then, the lottery balls enter the collection path  350  below the discharge path  347 A. When all of the lottery balls have been discharged, the open/close shutter  344 A is rotationally driven by 90 degrees again by the motor  345  and is closed. Since an discharging mechanism does not have to be provided to each of all of the lottery holes  340  but one centralized discharging mechanism can be provided because of this configuration, the mechanism can be simplified and the costs for producing the gaming machine can be reduced. The number of lottery balls (number of balls) discharged from the discharge path  347 A in each unit time depends on the speed of rotation of the lottery wheel  338 . As the speed of rotation of the lottery wheel  338  increased, the number of lottery balls to be discharged in each unit time increases.  
      Gaming Terminal  
      The gaming terminal  314 A in the gaming machine  310  will be described with reference to  FIG. 8 .  FIG. 8  is a perspective view showing an operation part of the gaming terminal  314  viewed from a player&#39;s position. Since the gaming terminals  314 B to  314 J have a configuration similar thereto, the description will be omitted herein.  
      The gaming terminal  314 A mainly includes a display device  370 A, a touch sensor  372 A ( FIG. 11 ), two dials  376 A and  377 A, a medal input port  378 A and a main control circuit  500 A ( FIG. 11 ).  
      The display device  370 A is provided in the upper part of the gaming terminal  341 A. A matrix card image for a bingo game assigned to a game player and other information or images relating to an optional game and so on are displayed on the display device  370 A. In other words, the display device  370  includes a plurality of boxes in a plurality of rows by a plurality of columns and displays a matrix in which indicias are assigned to the respective a plurality of boxes. Furthermore, as described later, on the condition that indicia selected by the main control circuit  400  or the like agrees with one of identification pieces assigned to the respective plural boxes, the main control circuit  500 A or the like controls to activate the box corresponding to one of the identification pieces and controls to give a dividend on the condition that a result from the control for activating has a predetermined form. Under this configuration, the game is developed with various kinds of information displayed on the display device  370 A being visually checkable by a game player.  
      Furthermore, a camera (not shown) for shooting entire images of the lottery wheels  338  and  339  may be provided in the lottery machine  312 . Then, by displaying a shot image on the display device  370 A, the lottery wheels  338  and  339  can be visually checked by a game player even when one of the lottery wheels  338  and  339  is hard to see.  
      Furthermore, a touch panel mainly including the touch sensor  372 A is provided in the display device  370 A. Thus, at the touch of the display device  370 A, a game environment allowing inputting various data or commanding can be provided to a game player.  
      While, in this embodiment, various input operations are allowed by the touch sensor  372 A, other operation forms may be adopted. For example, a plurality of operation buttons may be provided therein so that various input operation can be performed.  
      A seat portion  374 A is provided on the game player side of the display device  370 A. The two dials  376 A and  377 A positioning as upper and lower layers are provided on the top surface of the seat portion  374 A. By using the dials  376 A and  377 A, a game environment, which is hard to operate only by pressing a normal operation button or touching the touch panel, can be provided to a game player.  
      For example, in this embodiment, on a bingo game matrix image displayed on the display device  370 A, an indicia assigned to a bingo box in the outer periphery of the matrix image can be moved to an adjacent bingo box along the outer periphery. In the past, when a second indicia needs to be moved continuously and when only pressing a normal operation button and touching the touch panel are allowed as operations, the operations must be performed again and again, which is significantly burdensome. Accordingly, by using input devices such as the dials  376 A and  377 A, continuous operations can be performed through one action. Thus, a highly operable game can be provided to a game player. Furthermore, operations can be performed very easily for analog movements such as scrolling on screens and moving a pointer thereon. Thus, a highly operable game can be provided to a game player.  
      The medal input port  378 A for inserting a medal is provided on the right side of the dials  376 A and  377 A. A medal sensor  380 A (see  FIG. 11 ) is provided within the metal slot  378 A. The medal sensor  380 A senses that a medal has been inserted to the medal input port  378 A. Thus, when a medal is inserted to the medal input port  378 A by a game player, the fact that the medal has been inserted is sensed by the medal sensor  380 A.  
      The main control circuit  500 A is placed within the seat portion  374 A and controls the above-described different devices.  
      System Configuration of Gaming Machine  
      A system configuration in the gaming machine  310  will be described with reference to  FIG. 9 .  
      As shown in  FIG. 9 , the gaming machine  310  mainly includes a lottery machine controller  360  for controlling the lottery machine  312  and the gaming terminals  314 A to  314 J.  
      The lottery machine controller  360  is communicably connected to the ten gaming terminals  314 A to  314 J. The lottery machine controller  360  can control the ten gaming terminals  314 A to  314 J by exchanging various kinds of data and signals with the  314 A to  314 J.  
      Electric Configuration of Lottery Machine  
      An electric configuration in the lottery machine  312  of the gaming machine  310  will be described with reference to  FIG. 10 .  
      As shown in  FIG. 10 , the ball entrance detection sensor  349  is connected to an interface circuit group  402  of a main control circuit  400 . When a lottery ball enters to one of the plurality of lottery holes  340  and  341  by the ball entrance detection sensor  349 , a predetermined signal is supplied to an input/output bus  404  through the interface circuit group  402 . The input/output bus  404  inputs/outputs data signals or address signals to a central processing unit (called CPU, hereinafter)  406 . The main control circuit  400  is placed on the control circuit substrate  353 . Thus, the main control circuit  400  placed on the control circuit substrate  353  functions as a detector for detecting the lottery hole  340  or  341  to which a lottery ball has entered based on a detect signal from a lottery ball passage detecting sensor  351 .  
      Furthermore, communication control circuits  414 A to  414 J are connected to the interface circuit group  402 . The communication control circuits  414 A to  414 J are used for communicably connecting the lottery machine controller  360  and the gaming terminals  314 A to  314 J.  
      A read-only memory (ROM)  408  and a random access memory (RAM)  410  are also connected to the above-described input/output bus  404 . The ROM  408  records a control program for controlling processing relating to a game in the lottery machine controller  360 . Furthermore, the ROM  408  stores initial data used for executing the control program and various programs. Furthermore, the RAM  410  stores values of flags and/or variants to be used in the above-described programs.  
      Furthermore, an interface circuit group  412  is connected to the input/output bus  404 . A lottery ball lifting motor  320 C, a rotation motor  326 , lottery wheel rotation motors  335  and  337 , a motor  345  for the open/close shutter  344 , the rocking device  346  and a reclosable gate  352  are connected to the interface circuit group  412 . Thus, the devices are controlled by the CPU  406  so that the above-described lottery machine  312  can be driven.  
      Electric Configuration of Gaming Terminal  
      An electric configuration of the gaming terminal  314 A of the gaming machine  310  will be described with reference to  FIG. 11 . Since the gaming terminals  314 B to  314 J have configurations similar thereto, the description will be omitted herein. Each of these gaming terminals functions as an apparatus for determining details of a game along with the main control circuit  400  of the lottery machine  312 .  
      As shown in  FIG. 11 , the medal sensor  380 A is connected to an interface circuit group  502 A of a main control circuit  500 A. When a medal is inserted through the medal input port  378 A by the medal sensor  380 A, a predetermined signal is supplied to an input/output bus  504 A through the interface circuit group  502 A. The input/output bus  504 A inputs/outputs data signals or address signals to a central processing unit (CPU)  506 A.  
      Furthermore, the touch sensor  372 A is also connected to the interface circuit group  502 A of the main control circuit  500 A. When the fact that a position displaying a command displayed on the display device  370 A is touched by a game player is detected, the touch sensor  372 A supplies a signal corresponding to the command to the interface circuit group  502 A.  
      Furthermore, the dials  376 A and  377 A are connected to the above-described interface circuit group  502 A. When the dial  376 A or  377 A is rotated by a game player, a signal corresponding to the angle of rotation is supplied to the interface circuit group  502 A.  
      Furthermore, a communication control circuit  514 A is connected to the interface circuit group  502 A The communication control circuit  514 A is communicably connected to the lottery machine controller  360  and the gaming terminal  314 A.  
      A read-only memory (ROM)  508 A and a random access memory (RAM)  510 A are connected to the above-described input/output bus  504 A. The ROM  508 A records a control program for controlling processing relating to a game in the gaming terminal  314 A. Furthermore, the ROM  508 A stores initial data used for executing the control program and programs for display control in the display device  370 A. Furthermore, the RAM  510 A stores values of flags and/or variants to be used in the above-described programs.  
      Furthermore, an interface circuit group  512 A is connected to the input/output bus  504 A. A speaker  586 A and a hopper  588 A are connected to the interface circuit group  512 A, and the interface circuit group  512 A supplies drive signals and drive power so as to control the above-described devices in accordance with results of computing processing in the CPU  506 A.  
      Furthermore, a display controller  600 A is connected to the interface circuit group  512 A. The display controller  600 A supplies image signals for displaying images to the display device  370 A based on an image display command supplied from the main control circuit  500 A.  
      Standby Screen of Gaming Terminal  
      A standby screen to be displayed on the display device  370 A of the gaming terminal  314 A will be described with reference to  FIG. 12 .  
       FIGS. 12 and 13  show an embodiment in which the invention is applied to a bingo game using a bingo card having 5.5 bingo boxes as described below. The conventional dominating bingo game includes drawing a predetermined number of numbers from 25 numbers at a probability of 1/25 for a bingo card having 5.5 bingo boxes, when a drawn number is on the bingo card, activating the bingo box corresponding to the number, and making a bingo hand by five activated bingo boxes in a horizontal, vertical or diagonal line. In this embodiment, instead of numbers acting as indicias used in a conventional bingo game, playing-card designs are used as indicias (where one joker or two jokers may be included or no joker may be included,.or a free spot having a specific bingo box activated irrespective of a drawn indicia may be regarded as a joker). Then, a lottery is performed at a probability of 1/52 (or at a probability of 1/53 or 1/54). In this case, in addition to conventional bingo hands, poker hands may be made (such as One Pair, Two Pair, Three Of A Kind, Straight, Flush, Full House, Four Of A Kind, Straight Flush, Royal Flush and Five Of A Kind), and a dividend in accordance with a bingo hand or poker hand is given to a game player. Furthermore, a poker hand and a bingo hand may be made in a specific same line on a bingo card at the same time, In this case, both of the dividend corresponding to the poker hand and the dividend corresponding to the bingo hand are given to a game player. However, bingo boxes are activated at a lower probability than that of a conventional bingo came, which lowers the possibility that a bingo hand is made. Accordingly, while a bingo hand is conventionally made by five activated bingo boxes in a horizontal, vertical or diagonal line, a bingo hand may be made by not only five but also three or four activated bingo boxes in a line.  
      Furthermore, receiving operations on the gaming terminal  314  in relation to a game is all by a touch panel method excluding operations through the dials  376 A and  377 A (See  FIG. 8  for both of them). In other words, the touch sensor  372 A (see  FIG. 11 ) is provided on the surface of the display device  370 A such that a game player can operate a gaming terminal that the game player intends by touching a predetermined touch portion of the display device  370 A. However, the invention is not limited thereto, but an operation receiving method not using a touch panel method may be adopted. For example, predetermined switches may be provided for receiving operations of a game player.  
       FIG. 12  is an example in which a screen for receiving an entry of a game through the gaming terminal  314  is displayed on the display device  370 A of the gaming terminal  314  and operations on a touch portion  480 , a touch portion  481  and the dials  376 A and  377 A (see  FIG. 8 ) for receiving an entry operation of a game are valid. other operations on the dial  376 A and/or dial  377 A (see  FIG. 8  for both of them) are invalid. Furthermore, medal insertion to the medal input port  378 A (see  FIG. 8 ) is also invalid, and an inserted medal is returned to a game player from a medal payout port  382 A. Furthermore, all of bingo boxes having playing-card designs in a matrix form on a bingo card displayed on the display device  370 A are also displayed darker or shaded so as to indicate that the bingo boxes do not still win in a lottery and are not activated. Activating a bingo box refers to processing for displaying a bingo box having the same pattern as a playing-card design drawn by the lottery machine  312 , if any, distinctively from the other bingo boxes hereinafter. Through the processing of activating a bingo box, the bingo box is displayed brighter or is unshaded, for example. Notably, a bingo box on a bingo card on the standby screen of the gaming terminal  314  is not activated based on a drawing of an indicia in the lottery machine  312 . Furthermore, the values of line odds and poker odds shown on the display device  370 A are not changed by any operations by a game player.  
      An arrangement of playing-card designs displayed on bingo cards having 5.5 bingo boxes displayed on the standby screen of the gaming terminal  314  is different from the arrangement on a bingo card to be used in a game after the game entry. Here, it is a display of a demonstration screen only, and an arrangement of playing-card designs displayed on a bingo card is not determined until the game entry.  
      An entry to a game is received when the touch portion  480  or touch portion  481  is touched by a game player. When the game entry is received by the gaming terminal  314 , the display is changed to the screen in  FIG. 13 .  
      Screen on Gaming Terminal After Game Entry  
      A screen after game entry to be displayed on the display device  370 A of the gaming terminal  314  will be described with reference to  FIG. 13 .  
       FIG. 13  shows a screen displaying a determined bingo card including 5.5 bingo boxes having playing-card designs. Here, playing-card designs are placed in an arrangement including a predetermined poker hand (such as a poker hand made by five playing cards, that is, Straight, Flush, Full House, Straight Flush or Royal Flush) on a specific line in advance. By preparing a high dividend hand on a bingo card in advance in this way, the expectations of a game player can be advantageously enhanced. Notably, playing-card designs are arranged at random in bingo boxes excluding the predetermined poker hand. The display of the touch portion  480  and touch portion  481  are eliminated, and the display of an entire condition notification unit  483 , which will be described later, appears. At the state on the screen, a BET operation based on medal insertion by a game player or an operation on the dial  378 A or  377 A (see  FIG. 8  for both of them) are valid for a certain period of time (such as a predetermined time like 45 seconds). For example, through a BET operation based on medal insertion by a game player, a predetermined number of medals are BET so that the level of line odds shown on a line odds table  482  can rise. Thus, the shaded part in the figure is moved upward in the figure, and the value indicating the odds level of the line odds in the figure rises (in  FIG. 13 , the shaded part positioned in the second row from the bottom of the line odds table  482 , and the odds level is 2). Furthermore, a predetermined number of medals are BET so that the value of the poker odds shown on a poker odds table  484  can increase and the value on the display of the odds level of the poker odds in the figure can increase in the same manner (in the figure, the odds values for poker hands are as displayed, and the odds level of the poker odds is 3). Odds level here refers to an index indicating the rank among hierarchies of odds values. In this case, odds values are divided into a predetermined number of hierarchies in accordance with the magnitudes of odds values. For example, the odds value may increase as the value of the odds level increases, or the odds value may decrease as the value of odds level decreases.  
      Also on the display device  370 A of the gaming terminal after a game entry, bingo boxes on a bingo card may be all displayed darker or shaded so that the bingo boxes are indicated as bingo boxes, which are not won in the lottery and are not activated.  
      When a BET operation based on medal insertion by a game player and an operation on the dial  376 A and/or dial  377 A (see  FIG. 8  for both of them) are valid, a game player can rotationally move a bingo box in the inner periphery  490  of the bingo card Hatched with lines oriented diagonally upward right as seen in  FIG. 13  by operating the dial  376 A and can rotationally move a bingo box in the outer periphery  491  of a bingo card Hatched with lines oriented diagonally downward right as seen in  FIG. 13  by operating the dial  377 A. More specifically, when a game player rotationally operates the dial  376 A counterclockwise by a predetermined amount, the bingo box in the inner radius  490  of the bingo cards is, in accordance thereto, also rotationally moved counterclockwise about the center of the bingo cards only by the predetermined amount. For example, when the dial  376 A is rotationally operated counterclockwise by an amount corresponding to the amount of movement equal to one bingo box, Queen of hearts positioning at the upper left corner of the inner radius  490  of the bingo cards in  FIG. 13  moves to a place having Jack of hearts, and Jack of hearts moves to a place having 3 of clubs. In this way, each of bingo boxes moves counterclockwise by one. This is also true for the rotational movement in the outer periphery  491  of the bingo card in response to an operation on the dial  377 A. Thus, a game player can move a bingo box rotationally in an arbitrary manner about the center of the bingo card. Then, the operation is an operation allowed as far as the operations can be received in the gaming terminal  314 . By allowing this kind of operation, bingo boxes must be moved not only to have an arrangement highly possibly making a bingo hand but also in consideration of a poker hand, which requires a strategy. Requiring a strategy means that bingo boxes rust be moved in consideration of whether Two Pair having a high possibility to be made while giving a low dividend is aimed or Royal Flush having a low possibility to be made while giving a high dividend is aimed.
