FIG. 2B is a side view showing the cron body 31 equipped in the game board 12. The croon body 31 has, for example, a cylindrical overall shape. The croon body 31 has a disk-shaped or mortar-shaped rolling plate 313, for example. In the rolling plate 313, a plurality of, here, three drop openings 315-1, 315-2, and 315-3 are opened. The drop opening 315-1 is a circle having a diameter through which a game ball can pass. The other drop openings 315-2 and 315-3 are also circles having the same diameter as the drop openings 315-1. The three drop openings 315-1, 315-2, and 315-3 are distributed at equal intervals on a circle concentric with the rolling plate 313. Drop port 315-2 is formed at the intersection of the circle and rotation axis RA1. The drop port 315-1 is positioned symmetrically with respect to the drop port 315-3 with the rotation axis RA1 in between. The game ball rolls on the rolling plate 313 and falls into one of the three drop openings 315-1, 315-2, and 315-3.

  The upper part of the rolling plate 313 is covered with a short cylindrical upper case 320 made of a highly transparent resin. A substantially circular introduction port 311 is opened at the center of the upper surface of the upper case 320, and a game ball is introduced into the interior of the cron body 31 through the introduction port 311. The lower side of the rolling plate 313 is covered with a lower cylindrical lower case 321 made of, for example, opaque resin. On the bottom surface of the lower case 321, three discharge ports 319-1, 319-2, and 319-3 for discharging the game balls introduced into the croon body 31 downward from the croon body 31 are opened. Three discharge ports 319-1, 319-2, and 319-3 are connected to three dropout ports 315-1, 315-2, and 315-3 on the rolling plate 313 with three guide paths 317-1 and 317-2. , 317-3. The game ball that rolls on the rolling plate 313 and falls from the drop port 315-1 is conducted through the guide path 317-1 and discharged from the discharge port 319-1. The game balls discharged from the discharge port 319-1 through the guide path 317-1 are oriented toward the stage entrance 19, and most of them enter the stage 20. Many of the game balls that have entered the stage 20 enter the starting port 16. Increasing the number of balls entering the starting port 16 increases the number of lotteries. Increasing the number of lotteries improves the payout rate. The game ball that rolls on the rolling plate 313 and falls from the drop port 315-2 is conducted through the guide path 317-2 and discharged from the discharge port 319-2. The game balls discharged from the discharge port 319-2 through the guide path 317-2 are oriented toward the normal winning port 18, and many of them win the normal winning port 18. When entering the normal winning opening 18, a certain number of game balls are paid out. The game ball that rolls on the rolling plate 313 and falls from the drop port 315-3 is conducted through the guide path 317-3 and discharged from the discharge port 319-3. The game balls discharged from the discharge port 319-3 through the guide path 317-3 are oriented toward the out port 21-2, and most of them are collected in the out port 21-2. An increase in the number of game balls collected in the out port 21-2 reduces the exit rate. That is, when the rolling plate 313 is tilted toward the dropping port 315-1, the exit rate is increased, and when the rolling plate 313 is tilted toward the dropping port 315-3, the exit rate is decreased. A standard exit rate is shown when the rolling plate 313 is horizontal. The gaming machine according to the present embodiment includes a mechanism for adjusting the inclination of the rolling plate 313, that is, the inclination of the croon body 31.

(Attitude change process by attitude control unit 151g)
FIG. 4 is a diagram illustrating a first posture and a second posture of the cron body 31 according to an embodiment of the present invention. The first posture and the second posture of the cron body 31 are synonymous with the first posture and the second posture of the rolling plate 313. The posture of the cron body 31 is switched between the first posture and the second posture according to the control of the posture control unit 151g. FIG. 4A is a diagram illustrating a first posture of the cron body 31. As shown in FIG. 4A, the first posture is a straight line RT (hereinafter referred to as a rolling plate reference line RT) that is orthogonal to the rotation axis RA1 and includes the diameter of the rolling plate 313, and is a horizontal line RH. On the other hand, the posture is inclined by a minute angle clockwise from the player's viewpoint about the rotation axis RA1, preferably an angle that cannot be recognized by the player, for example, 1 °. In the first posture, the circle center of the drop port 315-1 is located below the circle center of the drop port 315-3. FIG. 4B is a diagram illustrating the second posture of the cron body 31. As shown in FIG. 4 (b), the second posture means that the rolling plate reference line RT is inclined by a small angle (for example, 1 °) counterclockwise from the viewpoint of the player around the rotation axis RA1 with respect to the horizontal line RH. It is a posture. In the second posture, contrary to the first posture, the circle center of the drop port 315-3 is positioned below the circle center of the drop port 315-1.

  In the first posture, the rolling plate 313 is inclined so that the drop port 315-1 is positioned below the drop port 315-3, so that the game ball rolls on the rolling plate 313 and falls to the drop port 315-1. Inevitably becomes larger than the number of game balls falling to the drop opening 315-3. The distribution rate for directing the game balls toward the stage entrance 19 when the croon body 31 is in the first posture exceeds 1/3 which is an equal probability. In this case, the output rate is higher than the standard value. On the other hand, in the second posture, contrary to the first posture, the rolling plate 313 is inclined so that the dropping port 315-3 is positioned below the dropping port 315-1. The number of game balls that move and fall into the drop opening 315-3 is inevitably larger than the number of game balls that fall into the drop opening 315-1. The distribution rate for directing the game balls toward the out-port 21-2 when the crew body 31 is in the second posture exceeds 1/3 which is an equal probability. That is, the output rate is lower than the standard value.

  Thus, the rate of the ball game machine 10 during the period when the croon body 31 is in the first position tends to be higher than the rate of the ball game machine 10 during the period when the croon body 31 is in the second position. is there. The period in which the cron body 31 is in the first posture is a period in which a sweet setting advantageous to the player with a high turnout is made. On the other hand, the period in which the croon body 31 is in the second posture is a period in which a difficult setting is made that is disadvantageous to the player with a low turnout rate. That is, if the attitude of the cron body 31 can be changed intentionally, the exit rate can be adjusted each time at the hole side.

  The posture change of the cron body 31 is made by the control of the posture control unit 151g. The attitude control unit 151g has a built-in timer, and changes the attitude of the cron body 31 under time management. For example, the timer is reset (initialized) when the ram clear switch 140 is pressed, and outputs the elapsed time from when the ram clear switch 140 is pressed. The posture control unit 151g controls the drive unit 33 in order to set the cron body 31 to a predetermined initial posture when the ram clear switch 140 is pressed. The initial posture of the cron body 31 is fixed to one of the first posture and the second posture. Here, the initial posture of the cron body 31 will be described as the first posture. The posture control unit 151g changes the first posture if the cron body 31 is in the second posture at the time when the ram clear switch 140 is pressed, and maintains the first posture if the cron body 31 is in the first posture. Therefore, the drive unit 33 is controlled. At the time when the ram clear switch 140 is pressed, the posture control unit 151g moves the cron body 31 from the initial posture to the opposite posture, in this case, from the first posture when the lapse of a predetermined time after the ram clear switch 140 is pressed. The drive unit 33 is controlled to change the posture to two positions. The posture control unit 151g periodically changes the posture of the clown body 31 with the total time of the period in the first posture and the period in the second posture as one cycle.

  FIG. 5 is an explanatory diagram for explaining posture change processing by time management of the posture control unit 151g according to an embodiment of the present invention. As shown in FIG. 5 (a), the posture control unit 151g sets the posture of the cron body 31 with a period of 12 hours for the first posture and 12 hours for the second posture for a total of 24 hours as one cycle. Change periodically. The posture control unit 151g changes the cron body 31 from the first posture to the second posture when 12 hours have passed since the ram clear switch 140 was pressed, and when the 12 hours have passed after that, The posture is changed from the second posture to the first posture. The posture control unit 151g repeatedly executes the posture changing process every 24 hours.

  Note that the first posture period and the second posture period may not be equivalent. As shown in FIG. 5B, the period in the first posture may be 14 hours, the period in the second posture may be 10 hours, and a total of 24 hours may be one cycle. Further, the second posture period may be more than 24 hours. As shown in FIG. 5C, the period in the first posture may be 15 hours, the period in the second posture may be 100 hours, and a total of 115 hours may be one cycle. Further, in one cycle, the first posture period and the second posture period may be reversed, that is, the initial posture may be the second posture.

  FIG. 6 is a diagram showing a change in posture of the cron body according to the embodiment of the present invention. An employee of the hall can adjust the exit rate by setting the time when the ram clear switch 140 of the ball game machine 10 is pressed. Here, the posture change period of the croon main body 31 is set so that the period in the first posture is 12 hours, the period in the second posture is 12 hours, and a total of 24 hours is one cycle (see FIG. 5A). ). The business hours of the hall are 14 hours from 9:00 to 23:00.

  As shown in FIG. 6 (a), the employees of the hall, for example, press the ram clear switch 140 at 8:30 before the business start time, so that the business hours of 14 hours from 9:00 to 23:00 Among them, 11 hours and 30 minutes from 9:00 to 20:30 are set as the first posture period (sweet setting period), and 2 hours and 30 minutes from 20:30 to 23:00 are set as the second posture period (spicy setting time). can do. Thus, by adjusting the pressing time of the ram clear switch 140, the first posture period within the business hours is intentionally set longer than the second posture period, and the rate of the ball game machine 10 is intentionally set. Can be high.

  As shown in FIG. 6 (b), by pressing the ram clear switch 140 at 24:00, employees in the hall, etc., can spend 3 hours from 9:00 to 12:00 in the business period from 9:00 to 23:00. The first posture period (sweet setting period), 11 hours from 12:00 to 23:00, can be set as the second posture period (spicy setting time). By adjusting the pressing time of the ram clear switch 140 in this way, the second posture period within the business hours is intentionally set longer than the first posture period, and the output rate of the ball game machine 10 is intentionally set. It can be kept low.

  In this way, the cron body 31 of the ball game machine 10 is forcibly returned to the initial posture when the ram clear switch 140 is pressed, and the posture is changed again at a predetermined cycle. The posture change cycle is characterized in that the total time of the period in the first posture with a high exit rate and the period in the second posture with a low exit rate is one cycle, and one cycle is longer than the business hours. Is. For example, if one cycle is 24 hours, employees in the hall, etc., know the posture change cycle of the croon body 31 and intentionally set the rate of departure after that day by timing the ram clear switch 140 to be pressed. Can be adjusted. Further, as shown in FIG. 5 (c), the cron body 31 changes its posture in a total period of 115 hours in which the period of the first posture is 15 hours (about business hours) and the period of the second posture is 100 hours. If the program is programmed as described above, the sunrise rate can be increased and the rate of several sunrises from the next day can be reduced by pressing the ram clear switch 140 immediately before the start of business.

  In the above description, the cron body 31 has a configuration in which the rolling plate 313 is accommodated in the cylindrical cases 320 and 321, but may have other configurations. FIG. 7 shows another configuration example of the cron body 31. FIG. 7A is a perspective view of the cron body 31. FIG. 7B is a side view showing the cron body 31 equipped in the game board 12. The croon body 31 has a rolling plate 313. The rolling plate 313 is accommodated in the case 324. Case 324 has a spherical shape. Moreover, the case 324 is opaque, the surface of the sphere is homogeneous, and what should be used as an index by which the player can recognize the posture of the cron body 31 such as a pattern, a pattern, and unevenness from the appearance is not drawn. The inner diameter of the spherical case 324 is longer than the diameter of the rolling plate 313, whereby the rolling plate 313 is arranged at a position shifted from the spherical center C1 of the case 324 to the bottom side by a distance of, for example, a half of the spherical radius. Has been. A circular window 325 is provided in front of the spherical case 324 and above the rolling plate 313. The window 325 may be simply opened, or a disc made of a transparent resin or the like may be fitted therein. Although the player can visually recognize the surface of the rolling plate 313 through the circular window 325, the player cannot visually recognize the periphery of the rolling plate 313. A game ball inlet 311 is opened at the top of the spherical case 324.

  The croon body 31 is supported by a support mechanism 32 so that a center line passing through the center C1 of the sphere and the center C2 of the window 325 is perpendicular to the game board 12, and the center line is a rotation axis RA2. . The cron body 31 changes between the first posture and the second posture by being rotated about the rotation axis RA2 according to the control of the posture control unit 151g.

  The cron body 31 is an opaque sphere on which no pattern or the like is drawn, the rotation axis RA2 of the cron body 31 is perpendicular to the game board 12, the rotation axis RA2 passes through the center C1 of the sphere, and the window 325 It is circular, the rotation axis RA2 passes through the center C2 of the window 325, the peripheral edge of the rolling plate 313 cannot be visually recognized from the window 325, these characteristics are that the player is inclined the croon body 31; Further, it is possible to realize an effect that it becomes difficult to determine whether the croon body 31 is in the first posture or the second posture.

  In the above description, the crune body 31 is alternately changed between the first and second inclined postures. However, the horizontal posture is added as the third posture, and the first to third postures are changed. Alternatively, it may be changed alternately between one of the first and second inclined postures and the third horizontal posture.

  It should be noted that although the present invention has been described by way of preferred embodiments of the present invention with specific examples, these specific examples may be used without departing from the broad spirit and scope of the present invention as defined in the claims.
