When the launch adjusting unit 17 is located at the reference position, the game ball is not launched.

  The game board 12 is provided with a large number of game nails 23 for changing the flow direction of the game ball, and further, an obstacle such as a windmill 24 is provided. In addition, an out port (not shown) for collecting game balls that have not won a prize is provided at the bottom of the game board 12.

  A concave space 25 is formed substantially at the center of the game board 12, and the winning ball lottery device 100 of the present invention is provided in the concave space 25. The winning ball lottery device 100 distributes the movable wing 20 that distributes permission / inhibition of game balls to the inside and the lottery unit 30 that distributes the supplied game balls to a plurality of paths and changes the game state according to the distribution result. And a storage unit 40 that temporarily stores the game balls that have passed through the movable blades 20 and entered the winning ball lottery device 100, and supplies a part of the stored game balls to the lottery unit 30. .

  A start winning opening 21 is provided below the game board 12, and a start winning opening passing sensor (not shown) is provided therein. When the game ball wins the start winning opening 21, it is detected by the start winning opening passing sensor that a predetermined number of winning balls are paid out from the pachinko machine 10 and the movable blade 20 opens and closes a predetermined number of times. The game ball can enter the winning ball lottery apparatus 100 only during the opening period of the movable blade 20.

  Next, the configuration of the winning ball lottery apparatus 100 of the present invention will be described in detail below. FIG. 2 is a perspective view of the winning ball lottery apparatus 100. The movable blade 20 as an introduction portion for introducing the game ball into the winning ball lottery device 100 is provided to be rotatable about the shaft portion 20a and is positioned at the open position or the closed position. The movable blade 20 may be driven by a solenoid (not shown), for example. When the movable blade 20 is in the open position, the introduction path into the winning ball lottery device 100 is in an open state, and the game ball can enter the winning ball lottery device 100 only during this open period. Note that a game ball that has entered the winning ball lottery device 100 during a period in which the movable blade 20 is open is detected by a movable blade passage sensor (not shown), and a detection signal is supplied to a main controller described later. It has become. A game ball that has passed through the movable blade 20 and is introduced into the winning ball lottery apparatus 100 is placed in a winning state.

  A game ball that has passed through the movable blade 20 and entered the winning ball lottery apparatus 100 is guided upstream of the guide passage 50. The guide passage 50 is provided between the movable blade 20 and the storage portion 40 and guides the game ball introduced from the movable blade 20 to the storage portion 40 provided downstream thereof. The guide passage 50 may have any form as long as it guides the game ball that has passed through the movable blade 20 to the storage unit 40. For example, the guide passage 50 may have a bowl shape so that the game ball does not fall off. The path for guiding the game ball to the storage unit 40 may meander or bend.

  The lottery unit 30 is configured by, for example, a mortar-shaped recess 31 provided on the bottom surface in the recess space 25 and a plurality of winning holes 32 to 34 formed on the bottom surface. When a game ball is supplied from the storage unit 40 to the lottery unit 30, the game ball turns along the wall surface of the recess 31 and is guided to the bottom surface to win one of the winning ports 32-34. . For example, any one of these winning openings 32 to 34 is a jackpot winning opening, and the other two are outliers. When the game ball wins a jackpot winning opening, a winning detection sensor (not shown) provided therein detects the winning, and the gaming state shifts to a jackpot state advantageous to the player. The jackpot game continues until a predetermined end condition is satisfied, and the player is given an opportunity to acquire a large number of game balls during the jackpot game period. On the other hand, when a game ball wins a winning slot, only a predetermined number of game balls are paid out, and the jackpot game is not executed. In other words, the lottery unit 30 distributes the supplied game balls to either the big win winning opening or the outlier, and causes a change in the gaming state according to the distribution result. In other words, it can be said that the jackpot lottery is made by the game ball sorting action provided by the lottery unit 30. Note that the configuration of the lottery unit 30 described above is merely an example, and is not limited to a mode in which game balls are distributed to any of the jackpot winning prize outlets and the outlets, and a mechanism for performing lottery to determine whether or not to change the gaming state is configured. Any form can be used.

  The storage unit 40 primarily stores the game balls that have been awarded through the movable blades 20 and the guide passage 50, supplies a part of the stored game balls to the lottery unit 30, Other storage balls that are not supplied are discharged to the discharge port 41. That is, only a part of the game balls introduced into the winning ball lottery device 100 and placed in the winning state are subject to the jackpot lottery by the lottery unit 30, and other game balls are accommodated in the discharge port 41 and are not subject to the jackpot lottery It is said.

  The game ball guided to the storage groove 42 via the guide passage 50 is stored in the storage groove 42. The storage groove 42 is provided with wall portions 43 and 44 on both sides thereof, so that a game ball in a storage state in the storage groove 42 does not fall off. The storage groove 42 has a downward slope toward the front, and the game ball guided to the storage groove 42 rolls forward. The storage groove 42 is formed with a width that allows one game ball to pass therethrough, and the game balls are stored in an aligned state in the order they are introduced into the winning ball lottery apparatus 100 as shown in FIG.

  At the foremost position of the storage groove 42, there is a rotating shaft portion 45 that is rotatably provided with its extending direction as a rotating shaft, and the rotating shaft portion 45 so as to be substantially perpendicular to the extending direction of the rotating shaft portion 45. The connected rotary discharge piece 46 is connected to the rotary shaft portion 45 at an angular position which is substantially perpendicular to the extending direction of the rotary shaft portion 45 and is different from that of the rotary discharge piece 46, and a game ball is further attached to the tip portion A game ball discharge control mechanism is provided, which includes a rotary attracting piece 47 provided with a magnet to be attracted. The rotating shaft portion 45 is connected to a motor (not shown), and a rotational driving force is supplied by the motor. The rotation discharge piece 46 and the rotation suction piece 47 connected to the rotation shaft portion 45 rotate integrally with the rotation shaft portion 45. When the rotary shaft 45 is in a stationary state, the rotary discharge piece 47 is positioned at an initial position facing the storage groove 41. Thereby, the rotation discharge piece 47 stops the rolling of the game ball at the head position stored in the storage groove 41. That is, the game ball that rolls forward toward the storage groove 42 is held in the storage groove 42 by the rotation discharge piece 47, and the subsequent game balls are aligned in the storage groove 42. It will be stored at.

  The game balls stored in the storage groove 42 are guided to the discharge port 41 or the lottery unit 30 by the rotation operation of the discharge control mechanism. 3A to 3F show the operation of the discharge control mechanism and the operation of the game ball brought about by the operation of the discharge control mechanism in a stepwise manner, and are views of the storage unit 40 as viewed from above. is there. Hereinafter, the operation of the game ball stored in the storage unit 40 will be described with reference to FIG. FIG. 3A shows a state where the discharge control mechanism is positioned at the initial position and is in a stationary state. As described above, when the rotary shaft portion 45 is in a stationary state, positioning is performed so that the rotary discharge piece 46 faces the storage groove 42. As a result, the game balls stored in the storage groove 42 are stored in a state in which the path is closed by the rotary discharge piece 46 and aligned in the storage groove 42.

When the rotary shaft 45 starts to rotate clockwise from the state of FIG. 3A, the rotary discharge piece 46 and the rotation suction piece 47 connected thereto start to rotate integrally with the rotary shaft 45. As a result, the path closed by the rotary discharge piece 46 is released. As shown in FIG. 2, since the bottom surface of the storage groove 42 is inclined downward toward the discharge port 41, the stored game ball at the head position rolls toward the discharge port 41. (Fig. 3 (b))
When the rotating shaft 45 further rotates, the game ball at the head position is accommodated in the discharge port 41, and the subsequent game ball moves toward the front of the storage groove 42. That is, the stored ball at the head position is not a lottery target by the lottery unit 30. When the rotary suction piece 47 passes the position facing the storage groove 46 as the rotary shaft 45 rotates, the second storage ball is moved to the rotary suction piece 47 by the magnet provided at the tip of the rotary suction piece 47. Adsorbed (FIG. 3C).

  When the rotating shaft portion 45 further rotates, the game ball adsorbed by the rotation adsorption piece 47 rotates integrally with the rotation adsorption piece 47 while maintaining the adsorbed state. Since the third and subsequent stored balls have their paths open, they all roll toward the discharge port 41 and are accommodated in the discharge port 41. That is, the third and subsequent stored balls are not subject to lottery by the lottery unit 30 (FIG. 3 (d)).

  When the rotating shaft portion 45 further rotates, the game ball adsorbed by the rotation adsorbing piece 47 comes into contact with the end portion of the wall portion 44 provided on the side surface of the storage groove 42 (FIG. 3E).

  When the rotation shaft 45 further rotates, the game ball adsorbed by the rotation adsorption piece 47 interferes with the wall portion 44 and cannot move together with the rotation adsorption piece 47, so that it is separated from the rotation adsorption piece 47. . That is, the wall portion 44 not only functions as a wall for preventing the storage groove 42 from falling off, but also functions as a separation wall that allows the game ball to separate from the rotary adsorption piece 47. As shown in FIG. 2, a downward inclined surface 48 toward the lottery unit 30 is formed immediately below the separation position of the game ball, and the game ball detached from the rotation suction piece 47 rolls along the inclined surface 48. Then, it is led to the lottery section 30 (FIG. 3 (f)).

  In this way, among the game balls stored in the storage unit 40, only the game ball in the next position of the head position, that is, the second storage ball is guided to the lottery unit 30 and is subject to the big hit lottery. A certain storage ball and the third and subsequent storage balls are accommodated in the discharge port 41 and are not subject to the jackpot lottery.

  Next, FIG. 4 shows a block diagram of a control system that performs operation control of the winning ball lottery apparatus 100 of the present invention. The main controller 200 is a part that controls the operation of the winning ball lottery apparatus 100, and includes a CPU that performs high-speed arithmetic processing, a ROM that stores an operation program executed by the CPU, and a RAM that temporarily stores processing items of the CPU. Consists of. The main controller 200 is supplied with each detection signal from the start winning port passing sensor 201, the movable blade passing sensor 202, and the rotary encoder 203. The rotary encoder 203 outputs a detection signal corresponding to the rotation angle position of the motor 205 for driving the rotation shaft unit 45 to rotate, and the rotation angle position information of the rotation shaft unit 45 is transmitted to the main controller 200 by the output signal. Is done. Based on these detection signals, the main controller 200 sends a control signal to a drive circuit 204 that supplies a drive signal to the movable blade drive solenoid 206 or a drive circuit 205 that supplies a drive signal to the rotary shaft drive motor 207. Supply and control the operation of the movable blade 20 and the discharge control mechanism. The drive circuits 204 and 205 supply drive signals to the movable blade drive solenoid 206 and the rotary shaft portion drive motor 207 in response to the control signal, thereby driving the movable blade 20 and the discharge control mechanism 45.

  FIG. 5 is a flowchart of the operation program of the winning ball lottery apparatus 100 performed by the main controller 200. Hereinafter, the operation of the winning ball lottery apparatus 100 will be described with reference to the flowchart of FIG. The main controller 200 acquires rotation angle position information of the rotation shaft portion 45 based on a detection signal from the rotary encoder 203 when the pachinko machine 10 is activated, and the angle position of the rotation shaft portion 45 is shown in FIG. The initial position is set (step S1). As a result, the game ball can be stored in the storage unit 40.

  Next, the main controller 200 determines whether or not the game ball has won the start winning opening 21 (step S2). When a game ball wins the start winning opening 21, a detection signal is supplied from the start winning opening passing sensor 201 toward the main controller 200. The main controller 200 recognizes the winning of the game ball at the start winning opening 21 based on the detection signal.

  When the main controller 200 recognizes that the game ball has won the start winning opening 21, it supplies a control signal to the drive circuit 204. The drive circuit 204 supplies a drive signal to the movable blade driving solenoid 206 in response to the control signal, and drives the movable blade 20 to the open state a predetermined number of times over a predetermined period (step S3). When the game ball passes through the movable blade 20 and is introduced into the winning ball lottery apparatus 100 within the open period of the movable blade 20, a detection signal is supplied from the movable blade passage sensor 202 toward the main controller 200. The game ball that has passed through the movable blade 20 is stored in the storage groove 42 via the guide passage 50. When a plurality of game balls are introduced into the winning ball lottery apparatus 100 within the movable blade opening period, the game balls are stored in the storage groove 42 in an aligned state in the order of introduction.

  Next, the main controller 200 determines whether or not a predetermined period has elapsed since the detection signal was supplied from the movable blade passage sensor 202 (step S4). That is, time measurement starts from the time when the game ball passes through the movable blade during the opening period of the movable blade 20, and a predetermined period is counted. For example, the predetermined period is set to a time longer than the time required for the game ball to pass through the movable blade 20 and be stored in the storage groove 42 via the guide passage 50. That is, the time for storing the game balls introduced into the winning ball lottery apparatus 100 in the storage groove 42 is secured by this predetermined period. The starting point for the predetermined period may be the time when the game ball passes through the start winning opening.

  When the main controller 200 determines in step S4 that the predetermined period has elapsed, the main controller 200 supplies a control signal to the drive circuit 205. The drive circuit 205 supplies a drive signal to the rotary shaft drive motor 203 in response to the control signal. Then, the rotation shaft 45 connected to the motor 203 starts to rotate clockwise, and the rotation discharge piece 46 and the rotation adsorption piece 47 connected to the rotation shaft 45 rotate integrally with the rotation shaft 45. Is started (step S5). The game balls stored in the storage groove 42 operate in the manner shown in FIGS. 3A to 3F, and only the second storage ball is supplied to the lottery unit 30, and the other storage balls are supplied to the discharge port 41. Be contained.

  The main controller 200 recognizes the rotation angle position of the rotation shaft portion 45 based on the detection signal supplied from the rotary encoder 203. When the main controller 200 determines that the rotation angle of the rotation shaft portion 45 has reached a predetermined angle at which the game ball adsorbed by the rotation adsorption piece 47 is released (step S6), the angular position of the rotation shaft portion 45 is shown in FIG. Positioning is performed at the initial position shown in a), and this routine is terminated (step S7).

  As is clear from the above description, according to the winning ball lottery apparatus of the present invention, the gaming balls that have passed through the movable blades and are in the winning state are stored in a state of being aligned with the storage unit, and the stored gaming balls Of these, only the second stored game ball is supplied to the lottery section and is subject to lottery, and the other stored balls are not subject to lottery. That is, unless at least two game balls are won, game balls are not supplied to the lottery unit. Therefore, even when the structure of the lottery part is a structure that makes it easy to win the jackpot winning opening, it is possible to prevent the winning probability of the game balls in the winning state from increasing to an inappropriate level. In other words, among the game balls that have passed through the movable blades and are in a winning state, the game balls that are to be selected by the lottery unit are selected by the storage unit provided in the preceding stage, so that the winning probability is below a certain value. It is kept.

  In the above embodiment, the case where the winning ball lottery device of the present invention is applied to a so-called feather-type game machine has been described as an example, but the present invention can also be applied to a so-called digipachi-type game machine. The Digi-Pachi type is equipped with a start winning opening, a symbol display device, and an attacker. A big win lottery is executed starting from winning at the starting winning opening, and when the big win is reached, the symbol display device is “777” or the like. A model that displays a predetermined big hit pattern and opens the attacker a specified number of times. When the winning ball lottery device of the present invention is applied to a digipachi type, for example, a game ball that has been put in a winning state through an introduction unit is stored in a storage unit, and only the second storage ball of the stored game balls is started. It will be supplied to the winning prize and will be the target of the big hit lottery. That is, in the case of the digital patch type, the start winning opening may be configured as a lottery section. The winning lottery apparatus of the present invention can also be applied to a so-called mixed-type pachinko machine having both the digipachi type function and the feather type function.
