Description

  The present invention provides a game board in which a game area is defined, a ball launching means for launching a game ball in the game area in response to an operation of an operation handle, and a flow of the game ball that is implanted in the game area The present invention relates to a gaming machine including a nail member that changes a direction, and a ball entrance that is arranged in the game area and into which a game ball can enter.

Conventionally, in general, in a pachinko machine as a gaming machine, a game ball is driven into a game area defined on a game board, and the game ball is arranged at a predetermined part of the game area (for example, a start prize port, When a prize is entered in a general prize opening, a big prize opening, etc., a game is performed by giving a player a predetermined number of prize balls for each prize. In addition, as such a prize opening (ball entrance), for example, as shown in Japanese Patent Laid-Open No. 2002-854 (Patent Document 1), the opening and closing operation of a pair of left and right movable wing pieces (opening and closing pieces) is used. Ordinary variable winning ball that can be transferred between one state (closed state, but game balls can be won) and a second state (open state) where game balls can be easily won compared to the first state. There has been proposed a device (variable pitching device) that forms a winning opening. Note that the normal variable winning ball apparatus is in the first state in the normal gaming state, and the display result of the normal symbol derived based on the establishment of a predetermined condition (for example, the passing of the gaming ball to the gate becomes a hit. Etc.), the control for shifting from the first state to the second state is performed.
Japanese Patent Laid-Open No. 2002-854 (FIG. 1)

  By the way, in the normal variable winning ball apparatus which can be shifted between the first and second states as in the above-mentioned Patent Document 1, the forward / backward movement of the plunger constituting the solenoid which is the electric drive source is rotated by the movable blade piece. The movable wing piece is opened / closed, that is, the prize opening is opened / closed by converting the movement into an operation. Specifically, in the first state, the plunger is advanced by moving the solenoid in a non-energized state, and the movable wing piece is rotated in the direction to close the winning opening, while in the second state, When the solenoid is energized, the plunger is moved backward, and the movable wing piece is rotated in the direction to open the winning opening. However, in such a configuration, in the first state, the movable wing piece is rotated in the direction to open the winning opening by applying a slight external force enough to retreat the plunger in the advanced state. Therefore, there has been a problem that the normally variable winning ball apparatus (winning hole) can be easily opened by fraud. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a gaming machine that can prevent the variable pitching device from being opened by an unauthorized external force.

(Solution 1)
In order to achieve the above object, a gaming machine of the present invention includes a gaming board in which a gaming area is defined, a ball launching means for launching a gaming ball in the gaming area in response to an operation of an operation handle, and the gaming A gaming machine comprising a nail member that is implanted in an area and changes a flow direction of a game ball, and a entrance that is arranged in the game area and into which a game ball can enter, The entry ball port is composed of a variable ball entry device having an opening and closing piece that can be shifted between a first state and a second state in which a game ball can be easily entered compared to the first state. The variable pitching device has a plunger that can advance and retreat, a solenoid that moves the open / close piece between the first state and the second state, and a forward / backward movement of the plunger. A drive transmission member that transmits as a transition operation of the It is provided movably between an engagement position that engages with the motion transmission member and an engagement release position that releases the engagement with the drive transmission member, and restricts movement of the drive transmission member at the engagement position. A locking member that locks the opening / closing piece in the first state, and the locking member connects the locking member and the plunger, and the opening / closing piece from the first state. A connecting portion for starting the movement of the lock member from the engagement position to the disengagement position substantially simultaneously with the start of movement of the plunger transitioning to the second state; The locking member is connected to the plunger and the lock member is disengaged after the movement of the plunger is started to move the opening / closing piece from the first state to the second state. The movement of the plunger from moving to the position, characterized in that it comprises a coupling engaging portion for transmitting a migration operation of the opening and closing piece.
In this case, in the first state, the movement of the plunger constituting the solenoid is transmitted to the opening / closing piece via the drive transmission member, and the opening / closing piece is in a closed state (including a state in which a game ball can be entered). On the other hand, in the second state, the movement of the plunger constituting the solenoid is transmitted to the opening / closing piece via the drive transmission member, and the opening / closing piece is opened. And in a 1st state, a lock member moves to the engagement position which engages with a drive transmission member with the movement of a plunger. Accordingly, the movement of the drive transmission member is restricted by the engagement with the lock member, and the opening / closing piece is locked in the first state. Further, when shifting to the second state, the lock member moves to the disengagement position where the engagement with the drive transmission member is released along with the movement of the plunger, so that the opening / closing piece is in the first state. Is unlocked, and the open / close piece shifts to the second state. Therefore, in the first state, since the opening / closing piece is in the locked state, even if an external force that can move the plunger is applied to the opening / closing piece, the opening / closing piece cannot be moved in the opening direction. It is possible to prevent the variable pitching device from being opened by an unauthorized external force.
Further, according to this configuration, when the opening / closing piece shifts from the first state to the second state, the lock member is moved from the engagement position to the engagement release position substantially simultaneously with the start of movement of the plunger serving as the driving force. After the movement is started and then the lock member is moved to the disengagement position, the movement of the plunger is transmitted as the movement of the opening / closing piece by the drive transmission member. For this reason, the unlocking operation of the open / close piece by the lock member (the movement operation of the lock member to the disengagement position) and the movement operation of the open / close piece to the second state by the drive transmission member (plan through the drive transmission member). The start timing of the movement of the jar to the opening / closing piece) can be made different. In other words, by shifting the output timing of the plunger that is the driving force of the initial action at the time of unlocking and at the start of the transition to the second state, the burden on the solenoid can be reduced and distributed as a result. In a configuration that enables locking, a smoother opening / closing operation of the opening / closing piece can be invited.

(Solution 2)
In the solving means 1, the solenoid includes a coil spring that spirally winds around the outer periphery of the plunger and constantly urges the plunger in the advance direction. The opening / closing piece moves to the first state by energizing force of the coil spring, and is energized when energized, and the plunger moves backward against the energizing force of the coil spring to move the opening / closing piece. To the second state.
In this case, the solenoid can be energized to retreat and move the plunger when shifting to the second state where game balls can be easily entered compared to the first state. For this reason, since the power is consumed only when the control for shifting the variable pitching device to the second state is given to the player as a special game value, the variable pitching device (opening / closing piece) is opened and closed. The operation can be performed economically.

(Solution 3)
In Solution 1 or Solution 2, the open / close piece includes a pair of left and right open / close pieces that form the entrance through a gap between the open and close pieces, and the pair of left and right open / close pieces respectively move the movement of the drive transmission member. Accordingly, it is provided so as to be rotatable between a vertical position in the first state and a tilt position in the second state.
In this case, the variable pitching device can be opened and closed by a rotation operation between the vertical position (first state) and the tilting position (second state) of the pair of left and right opening / closing pieces. In addition, with such a configuration, when the variable pitching device is opened, the opening amount of the pitching port can be efficiently earned with a small movement amount (rotation amount) of the opening / closing piece, so that the variable pitching can be efficiently performed. The ball device can be opened and closed.

(Solution 4)
In Solution 1 to Solution 3, the drive transmission member rotates the drive transmission member in addition to the coupling engagement portion that couples the solenoid and the drive transmission member by engagement with the plunger. A pair of pivot shafts that are freely attached, a transmission engagement portion that transmits the pivoting operation of the drive transmission member about the pivot shaft portion to the opening / closing piece by engagement with the opening / closing piece; A lock engaging portion that locks the rotation operation of the drive transmission member by engagement with the lock member, and releases the rotation lock of the drive transmission member by releasing the engagement with the lock member; The opening / closing piece includes an engagement protrusion that converts a rotation operation of the drive transmission member into a movement operation of the opening / closing piece by engagement with the transmission engagement portion.
In this case, the open / close piece can be shifted between the first state and the second state by transmitting the forward / backward movement of the plunger constituting the solenoid to the open / close piece via the rotation operation of the drive transmission member. Can be configured.

(Solution 5)
In the solving means 4, the connection engaging portion is formed in a shape that provides a slight gap between the distal end portion of the plunger in a connected state of the drive transmission member and the solenoid. It is attached in a loosely fitted state with some play in connection engagement.
In this case, when an external force is applied due to fraud, etc., the external force is absorbed by a slight play between the coupling engagement portion and the distal end portion of the plunger, so that it is directly applied to the opening / closing piece, the drive transmission member, or the solenoid. Since this is not the case, it is possible to avoid breakage of various components due to the locking of the opening / closing piece (the entrance).

(Solution 6)
In the solving means 4 or 5, the engaging protrusion is formed of a synthetic resin material so that the inside can be visually recognized and is integrally formed with the piece main body of the opening and closing piece. Functions as a maintenance department corresponding to force.
In this case, the engaging protrusion of the opening / closing piece that converts the rotation operation of the drive transmission member into the movement operation of the opening / closing piece is formed of a synthetic resin material so that the inside is visible and is integrally formed with the piece main body of the opening / closing piece. Functions as a maintenance department. Specifically, from the configuration in which the inside of the engaging protrusion is visible, it is possible to determine whether or not bubbles are included in the engaging protrusion at the manufacturing stage of the variable pitching device. Therefore, it becomes possible to sort out defective products whose engagement protrusions contain air bubbles and reduce the strength of the engagement protrusions and remove them at the manufacturing stage, thereby improving the manufacturing quality of the variable pitching device. it can. As a result, the opening and closing operation of the variable pitching device (the pitching port) can be smoothly performed continuously. In addition, since the piece main body and the engaging projection portion of the opening / closing piece are integrally formed, the strength of the boundary portion between the piece main body and the engagement projection portion can be increased. For example, in order to improve the maintainability of the opening / closing piece (specifically, in order to avoid damage and breakage of the engaging protrusion), the engaging protrusion is constituted by another member made of a metal rod or the like. Is attached to the open / close piece piece body, the number of parts constituting the open / close piece is increased, and the attachment portion is liable to be loose in attachment such as insertion of another member (metal rod, etc.). Arise. On the other hand, in the above-described configuration, the engagement protrusion is formed integrally with the open / close piece piece main body, so that the open / close piece is not increased without increasing the number of parts and without causing partial backlash. Can improve the maintainability. Further, when the entire opening / closing piece is integrally formed of a synthetic resin material in this way, since there is no foreign matter mixed in, it becomes easy to melt the opening / closing piece and recycle it as a raw material.

(Solution 7)
In the solution 6, the opening / closing piece is colored except for the engagement protrusion and a portion that can be visually recognized by the player in the assembled state of the variable pitching device.
In this case, the decorativeness of the variable pitching device can be enhanced by coloring and painting the opening / closing piece formed of a synthetic resin material whose inside is visually recognizable. Even in this case, the engaging protrusion that receives the driving force of the solenoid via the drive transmission member is not colored and can be visually recognized inside. Can be confirmed by inspection. Also, if the engaging projections are painted with different colors to enhance the decorativeness of the variable pitching device, that is, if the main body of the opening and closing piece and the engaging projections are painted in two colors, Due to the nature of this, cracks and the like are likely to occur at the boundary of the coating, and the strength of the engaging protrusion (especially the boundary with the main body) deteriorates. The decorativeness of the variable pitching device can be enhanced without incurring deterioration.

(Solution 8)
In Solution 1 to Solution 7, the variable pitching device is an attachment in which the opening / closing piece, the solenoid, the drive transmission member, and the lock member are integrally assembled to attach the variable pitching device to the game area. A substrate is provided.
In this case, by assembling various constituent members (opening / closing piece, solenoid, drive transmission member, and lock member) to the mounting base, the variable pitching device can be configured as a unit. Attaching to and removing from the game area (game board) can be facilitated.

(Solution 9)
In the solving means 1 to 8, the passing ball detecting means which is arranged in the game area and moves the variable pitching device from the first state to the second state based on the passing detection of the game ball. Is provided.
In this case, when the game ball is driven into the game area, the variable pitching device is shifted from the first state to the second state based on the passage detection of the game ball by the passing ball detection means. Become. In other words, the variable ball entry device can be shifted to the second state in accordance with the ball flow of the game ball that has been struck, so that it is possible to suppress a decrease in interest in the ball flow of the game ball in the game area. .

(Solution 10)
In the solving means 9, a random number extracting means for extracting a random number based on the passing detection of the game ball by the passing ball detecting means, and the variable pitching apparatus based on the random number value extracted by the random number extracting means as the first Transition determining means for determining whether or not to shift from the state to the second state, and based on the determination that the transition determining means shifts to the second state. Transition control means for performing transition control to the second state in a predetermined period.
In this case, if there is a passing detection of the game ball by the passing ball detection means, the variable pitching device is not necessarily shifted to the second state, but a lottery is performed based on the detection of the passing of the gaming ball by the passing ball detection means, Since the variable pitching device can be configured to shift to the second state only when the lottery result is a win, the rare value of the gaming privilege for shifting the variable pitching device to the second state can be increased. .

(Solution 11)
In solution means 1 to solution means 10, a start winning opening arranged in the game area and capable of winning a game ball, a winning detection means for detecting that a game ball has won the start winning opening, and at least the A ball payout means for paying out a predetermined number of game balls according to the detection of the game balls by the winning detection means, and a determination as to whether or not a profit should be given to the player based on the detection of the game balls by the winning detection means. A winning determination means, and a profit granting state control means for controlling to a profit granting state that grants a profit to the player based on the determination that the player should be given a profit by the corresponding winning determination means, The start winning opening is composed of the variable pitching device.
In this case, the winning determination is performed based on the winning at the start winning opening constituted by the variable pitching device, and the state is controlled to a profit granting state in which a profit is given to the player when the determination result is a win. For this reason, in the determination of whether or not to enter the profit granting state, winning at the starting prize opening is the most important opportunity, so the second state of the variable pitching device that greatly influences winning at the starting prize opening The player's interest in the transition to can be greatly increased.

(Solution 12)
In the solving means 11, the display means arranged in the game area to display the symbol information in a variable manner, and the display means to display the symbol information in a variable manner on the basis of the determination result of the winning determination means, and after a predetermined period has passed. Display that stops displaying the display result of the symbol information according to the determination result, and stops displaying the specific display result as the display result of the symbol information when it is determined by the winning determination means that a profit should be given to the player Control means.
In this case, since the winning determination based on the winning at the start winning opening can be produced by the change display of the symbol information by the display means, it is possible to suppress a decrease in visual interest.

(Solution means 13)
In the solving means 11 and the solving means 12, when the profit granting state control means controls the profit granting state, it shifts from the closed state to the open state and has a big winning prize that allows a large number of game balls to win. With mouth device.
In this case, it is possible to give the player as a profit granting state that a large amount of prize balls are paid out to the player in accordance with winning in the big winning opening.

(Solution 14)
In Solution 1 to Solution 13, the game machine is a pachinko game machine.
The basic configuration of the pachinko gaming machine is that a game ball is driven into the game area in accordance with the operation of the operation means, and the displayed game ball is awarded on the start opening provided in the game area. The symbol information is variably displayed by the means, and the display result of the symbol information is stopped and displayed. In addition, when a profit granting state (for example, a big hit gaming state) occurs, a big winning opening provided in the gaming area is opened in a predetermined manner so that a game ball can be won, and a game is given to the player based on the winning. A privilege (for example, awarding a prize ball or writing a point on a magnetic card) is granted.

It is rotatably attached in the C1-C2 direction (see FIGS. 8A and 9A). At this time, a gap space between the open / close pieces 73 and 74 is formed as a start winning opening 72, and below that, a game ball that has entered the starting winning opening 72 is received and rearward (opening of the mounting base 71). A guiding portion 90 of the ball receiving member 75 is arranged to guide from the portion 82 to the ball passage portion 85b). Further, in such attachment, each of the engaging protrusions 87b protruding from the rear side of the opening and closing pieces 73 and 74 is inserted into the opening 82 of the attachment base 71 and protrudes into the cylindrical housing portion 85. Placed in.

  On the other hand, a drive transmission member 76 and a slide lock member 77 are mounted in a cylindrical housing portion 85 on the rear surface side of the bowl-shaped base portion 81 constituting the mounting base 71. That is, the drive transmission member 76 is engaged with the engagement protrusions 87b of the opening and closing pieces 73 and 74 whose U-shaped transmission engagement portions 93a and 93b individually protrude into the cylindrical housing portion 85. In this state, the pivot shaft portions 92 a and 92 b are pivotally engaged with the shaft support cutout portions 85 c and 85 d of the mounting base 71, so that the pivot shaft portions 92 a and 92 b are rotatably mounted in the cylindrical housing portion 85. The drive transmission member 76 is attached so as to be rotatable in the A1-A2 direction (see FIGS. 8B and 9B) around the rotation shaft portions 92a and 92b. Further, the slide lock member 77 is attached to be slidable in the front-rear direction by loosely fitting the lock base 96 to the slide attachment portion 85 a in the cylindrical housing portion 85.

  Further, the start port solenoid 67 is attached to the rear side of the cylindrical housing portion 85 of the mounting base 71 in a state where the plunger 67 a is connected to the drive transmission member 76 and the slide lock member 77 in the cylindrical housing portion 85. . That is, the start port solenoid 67 has a hook-like shape of the housing case 99 in a state in which the distal end portion of the plunger 67 a is connected and engaged with the connection engaging portion 94 of the drive transmission member 76 and the connection recess 98 of the slide lock member 77. The flange portions 99a and 99b (mounting holes 100a and 100b) are screwed to the screw-fixing bosses 86a and 86b of the mounting base 71 so that they are integrally mounted on the rear side of the mounting base 71 (tubular housing portion 85). . The variable prize winning device 70 constituted by assembling various components as described above is attached to the surface of the game board 4 by screwing the mounting base 71 through the mounting holes 80a and 80b, thereby allowing the game area 12 in a predetermined area.

  Next, the opening / closing operation of the opening / closing pieces 73 and 74 (start winning opening 72) constituting the variable winning device 70 will be described with reference to FIGS. However, the closing of the opening / closing pieces 73 and 74 (starting winning opening 72) described below is a state in which it is relatively difficult to win the starting winning opening 72 as compared to the open state. The win itself is still possible.

  First, the closed state (first state) of the open / close pieces 73 and 74 will be described with reference to FIG. 8. As shown in FIGS. 8A and 8B, the start opening solenoid 67 is in a non-energized state when closed. When the excitation is released, the plunger 67a is moved forward by the urging force of the coil spring 67b. As a result, the drive transmission member 76 in which the coupling engagement portion 94 is coupled and engaged with the distal end portion of the plunger 67a rotates in the A1 direction around the rotation shaft portions 92a and 92b as the plunger 67a moves forward. . The open / close pieces 73 and 74 whose engaging protrusions 87b are individually engaged with the transmission engaging portions 93a and 93b of the drive transmission member 76 are the drive transmission members 76 (transmission) centering on the rotation shaft portions 92a and 92b. As the engaging portions 93a and 93b) rotate in the A1 direction, the engaging protrusion 87b is pushed down. Therefore, the left opening / closing piece 73 is rotated in the B1 direction around the shaft protrusion 91a by the depression of the engaging protrusion 87b, so that the piece main body 87 is in a vertical state as shown in FIG. The right opening / closing piece 74 is rotated in the C1 direction around the shaft projection 91b and moved to the vertical position by pushing down the engagement projection 87b, thereby moving to the start winning opening 72. The closed state is relatively difficult to win.

  Further, in the closed state of the open / close pieces 73 and 74 (start winning prize opening 72), the open / close pieces 73 and 74 are centered on the shaft protrusions 91a and 91b by the engagement of the slide lock member 77 and the drive transmission member 76. The pivoting movement is locked. Specifically, the drive transmission member 76 rotates in the A1 direction as the plunger 67a moves forward by releasing the excitation of the start port solenoid 67, so that the lock engagement portion 95 of the drive transmission member 76 is in a substantially vertical position. It will be in the state which moved to. The slide lock member 77 slides forward (D1 direction) as the plunger 67a moves forward. Thereby, the engagement lock portion 97 of the slide lock member 77 is engaged with the lock engagement portion 95 of the drive transmission member 76. That is, the lower end portion of the engagement lock portion 97 is in contact with the upper end portion of the lock engagement portion 95. For this reason, the rotation operation is locked around the rotation shaft portions 92a and 92b of the drive transmission member 76, and as a result, the opening and closing pieces 73 and 74 engaged with the drive transmission member 76 (transmission engagement portions 93a and 93b). The rotation operation is locked around the shaft protrusions 91a and 91b of the (engagement protrusion 87b). Accordingly, even when an external force is applied to the opening and closing pieces 73 and 74 (the B2 direction of the opening and closing piece 73, the C2 of the opening and closing piece 74) when the opening and closing pieces 73 and 74 (start winning prize opening 72) are closed, The open / close pieces 73 and 74 (start winning prize opening 72) are maintained in a closed state without being opened. When an external force is applied in this way due to an illegal act or the like, the external force is absorbed by the slight play between the connecting engagement portion 94 and the distal end portion of the plunger 67a described above. 74, the drive transmission member 76, or the start opening solenoid 67 is not applied, so that damage to various components accompanying the locking of the open / close pieces 73, 74 (start winning prize opening 72) is avoided.

  Next, the open state (second state) of the open / close pieces 73 and 74 will be described with reference to FIG. 9. As shown in FIGS. 9A and 9B, the start port solenoid 67 is energized when open. By being excited, the plunger 67a moves backward against the urging force of the coil spring 67b. As a result, the drive transmission member 76 in which the connection engaging portion 94 is connected and engaged with the distal end portion of the plunger 67a rotates in the A2 direction around the rotation shaft portions 92a and 92b as the plunger 67a moves backward. . The open / close pieces 73 and 74 whose engaging protrusions 87b are individually engaged with the transmission engaging portions 93a and 93b of the drive transmission member 76 are the drive transmission members 76 (transmission) centering on the rotation shaft portions 92a and 92b. As the engaging portions 93a and 93b) rotate in the A2 direction, the engaging protrusion 87b is pushed up. Accordingly, the left opening / closing piece 73 is rotated in the B2 direction around the shaft projection 91a by pushing up the engagement projection 87b, and the piece main body 87 is in the tilted state as shown in FIG. 9A. The right opening / closing piece 74 is rotated in the C2 direction around the shaft projection 91b and moved to the tilting position by pushing up the engagement projection 87b. The open state is relatively easy to win.

  When the opening / closing pieces 73 and 74 (start winning prize opening 72) are opened, the slide lock member 77 and the drive transmission member 76 are automatically engaged, in other words, the opening and closing pieces 73 and 74 are in the rotationally locked state. The opening and closing pieces 73 and 74 (start winning prize opening 72) are opened smoothly by being released. Specifically, the slide lock member 77 slides rearward (D2 direction) in accordance with the backward movement of the plunger 67a due to the excitation of the start port solenoid 67, so that the engagement lock portion 97 of the slide lock member 77 is driven. The engagement of the transmission member 76 with the lock engaging portion 95 is released. As a result, the backward movement of the plunger 67a is transmitted as it is as the turning operation of the drive transmission member 76 in the A2 direction, and the turning operation of the opening / closing piece 73 in the B2 direction and the turning operation of the opening / closing piece 74 in the C2 direction. As a result, the opening and closing pieces 73 and 74 (start winning prize opening 72) are smoothly opened.

  By the way, the pair of left and right open / close pieces 73 and 74 forming the start winning opening 72 are each formed of a transparent synthetic resin material, and a part of the piece main body 87 other than the engaging protrusion 87b, in other words, the variable winning device 70. The portions of the opening and closing pieces 73 and 74 that can be visually recognized by the player in the assembled state are decoratively colored. Therefore, whether or not air bubbles are contained in the engaging protrusions 87b of the opening / closing pieces 73, 74 made of a synthetic resin material in the manufacturing stage of the variable winning device 70 (before the colored opening / closing pieces 73, 74 are colored). Can be determined. Accordingly, it is possible to select defective products in which bubbles are included in the engaging protrusions 87b and the strength of the engaging protrusions 87b is reduced, and to remove them at the manufacturing stage, thereby improving the manufacturing quality of the variable winning device 70. be able to. Moreover, the decorativeness of the variable winning device 70 can be enhanced by painting the opening / closing pieces 73 and 74 formed of a transparent synthetic resin material. However, even in this case, the engaging protrusion 87b that receives the driving force of the start port solenoid 67 via the drive transmission member 76 is transparent without being colored, so that the engaging protrusion due to deterioration over time or the like. The degree of damage 87b can be confirmed by inspection.

  FIG. 10 schematically shows a configuration for controlling the operation of the pachinko machine 1. The control of the pachinko machine 1 is roughly divided into a main board group and a peripheral board group, and among these, the main board group plays game operations (winning detection, winning judgment, special symbol display, prize ball payout, etc.) ), And a group of peripheral boards controls production operations (light emission decoration, sound output, liquid crystal display, etc.). All of these boards are installed on the back side of the pachinko machine 1 and are normally visible or operated from the front side unless the main body frame 3 is opened after unlocking the main body frame 3. There is no. In addition to this, the pachinko machine 1 is equipped with a power supply board, a launch control board, an interface board (in the case of a CR machine), and the like. Is omitted.

  The main board group includes a main control board 101 and a payout board 105. The main control board 101 (winning determination means, profit provision state control means) includes a CPU 102 as a central processing unit, a ROM 103 as a read-only memory, a RAM 104 as a readable / writable memory, and the like. Among these, the CPU 102 executes a game control program stored in the ROM 103 and controls various games performed in the pachinko machine 1 in accordance with the execution. Further, the CPU 102 creates a command to be transmitted to the peripheral board group or the payout board 105. The RAM 104 temporarily stores information such as various data and input signals generated in various processes executed by the main control board 101.

  The main control board 101 is connected with a start port switch 46, a gate switch 49, and a count switch 64. Detection signals are input to the main control board 101 from these switches. Specifically, when the game ball passes through the gate 58 in the process of flowing down, the passage is detected by the gate switch 49 and a detection signal is input to the main control board 101. When the game ball wins the start winning opening 72, a detection signal is input from the start opening switch 46 to the main control board 101. Further, when a game ball wins the big winning opening 61 during the big hit game, a detection signal is inputted from the count switch 64 to the main control board 101. And CPU102 performs the process according to these input detection signals. That is, the CPU 102 outputs respective drive signals to the various solenoids 63 and 67, the special symbol display LED 41, the normal symbol display LED 43, the special symbol start memory LED 68, and the universal diagram start memory LED 69 based on the input detection signal. To do. Further, the CPU 102 outputs a payout command for instructing payout of the game ball according to the winning to the payout board 105.

  The payout board 105 also includes a payout CPU 106 as a central processing unit, a payout ROM 107 as a read-only memory, and a payout RAM 108 as a readable / writable memory. When a winning of a game ball is detected by the start port switch 46 or the count switch 64 described above, a detection signal is input to the main control board 101 from each switch. In the main control board 101, a payout command for instructing the payout board 105 to pay out a specified number of game balls is transmitted from the CPU 102 based on the input detection signal. Then, the payout board 105 processes the payout command received from the main control board 101 and outputs a drive signal to the payout device 130 (ball payout means) to execute payout of a specified number of game balls. As a result, the specified number of game balls are actually paid out by the payout device 130.

  In addition, a launch device 140 having a launch motor is connected to the payout board 105, and the launch device 140 can perform an operation of launching a game ball toward the game area 12 using the power of the launch motor. it can. When the player operates the operation handle 18 (twisting operation), the firing motor of the launching device 140 is driven, and thereby a game ball is launched.

  Although not shown in FIG. 10, the launching device 140 incorporates a touch sensor for detecting that the player's body is touching the operation handle 18. The firing device 140 is in a state in which the firing motor can be driven when it is detected that the player is touching the operation handle 18. In this state, when the operation handle 18 is twisted clockwise from the initial position, the launching device 140 actually drives the launching motor to launch the game ball.

  Alternatively, a lower plate full tank switch is provided for detecting that the lower plate 17 is full, that is, the lower plate 17 is filled with paid out game balls, and a detection signal from the lower plate full tank switch is input. When the operation is performed, the control of making the operation handle 18 unacceptable can be performed, thereby making it impossible to drive the firing motor by the launching device 140. That is, the game balls paid out from the payout device 130 are first stored in the upper plate 28, but when the number of game balls that cannot be stored in the upper plate 28 is paid out, the game balls cannot be stored. Minute game balls are stored in the lower plate 17 communicating with the upper plate 28. In this state, the game ball is further paid out by the payout device 130, and when the lower plate 17 is finally full, a detection signal is output from the lower plate full tank switch, so that the operation of the operation handle 18 is accepted. Controlled to an impossible state. Further, in this case, when the detection signal from the lower pan full switch is not output, a control may be performed so that the operation handle 18 is returned to a state where the operation handle 18 can be accepted.

  The peripheral board group includes a sub-integrated board 111, a lamp driving board 119, an accessory control board 115, a display control board 120, and the like. Of these, the sub-integrated board 111 (display control means) includes an integrated CPU 112, an integrated ROM 113, and an integrated RAM 114. The sub-integrated board 111 also includes a sound source IC 128 that performs control related to sound output, and a sound ROM 127 as a read-only memory related to sound output. The integrated CPU 112 executes a process based on the effect command received from the main control board 101 by executing the effect control program stored in the integrated ROM 113. Further, the integrated RAM 114 temporarily stores various data and input / output signals generated in various processes executed by the sub-integrated board 111, information such as effect commands received from the main control board 101, and the like. When the integrated CPU 112 reads the effect command stored in the RAM 114, the integrated CPU 112 transmits a display command to the display control board 120 based on the read effect command, or sends a lamp lighting signal or solenoid to the lamp drive board 119. A drive signal is transmitted, or a drive signal is output to the side decoration device (frame lamp) 27. In addition, the sub-integrated board 111 reads the sound output mode based on the effect command by the sound source IC 128 from the sound ROM 127 and outputs a drive signal corresponding to the read sound output mode to the various speakers 14 and 36.

  The lamp driving board 119 transmits the lamp lighting signal received from the sub integrated board 111 to the side lamp 65. The display control board 120 includes a display CPU 121 as a central processing unit, a display ROM 122 as a read-only memory, and a display RAM 123 as a readable / writable memory. Among these, the display CPU 121 controls the liquid crystal display 42 based on a display command from the sub integrated substrate 111.

  Next, various control processes executed by the main control board 101 in accordance with the game progress of the pachinko machine 1 will be described with reference to FIGS. FIG. 11 is a flowchart showing an example of main processing executed by the CPU 102 mounted on the main control board 101. FIG. 12 is a flowchart illustrating an example of a process when a power failure occurs. FIG. 13 is a flowchart illustrating an example of timer interrupt processing. FIG. 14 is a list showing random numbers updated on the main control board 101. FIG. 15 is a flowchart showing an example of the game process. FIG. 16 is a flowchart showing the variation start process. FIG. 17 is a flowchart illustrating an example of the big hit determination process. FIG. 18 is a flowchart illustrating an example of the variable display pattern setting process. FIG. 19 is a list showing an example of the variable display pattern table. The timer interrupt process is executed by the CPU 102 mounted on the main control board 101 at a predetermined timing (in this embodiment, every 4 ms).

  As shown in FIG. 11, when the supply of power to the pachinko machine 1 is started, the CPU 102 executes a power-on process (step S1). In this power-on process, it is determined whether or not the backup data stored in the RAM 104 is normal (is a set value when a power failure occurs). If normal, the backup data stored in the RAM 104 is used. Executes processing to restore the power outage (power recovery processing), and if the backup data is abnormal, clears RAM104 and performs CPU peripheral device settings (normal initial settings: interrupt timing settings, etc.) . When power supply to the pachinko machine 1 is stopped during the game, the current game state is stored in the RAM 104 as backup data. If the RAM erase switch for instructing the clearing of the backup data stored in the RAM 104 is turned on in the power-on process, the RAM 104 is cleared and normal initialization is performed. If no backup data is stored in the RAM 104 mounted on the main control board 101 in the power-on process, the RAM 104 is cleared and normal initial setting is performed. In the power-on process, a process of setting a power-on command indicating that the main control board 101 is activated to the sub-integrated board 111 when normal initial setting is executed is also executed. The power-on command notifies the sub-integrated board 111 that the main control board 101 has been activated. Note that the backup data is also stored in the RAM 104 even when the power supply to the pachinko machine 1 is stopped (when the power is turned off) when the amusement store is closed or the like, and the power supply when the power supply to the pachinko machine 1 is started again. Processing at the time of execution is executed.

  When the power-on process ends, the CPU 102 starts a loop process that repeatedly executes each process for gaming. At the start of this loop processing, the CPU 102 first determines whether or not a power failure notice signal has been detected (step S2). In this embodiment, the power supply voltage used in the pachinko machine 1 is generated by a power supply board (not shown). That is, since a plurality of types of devices mounted on the pachinko machine 1 operate with different power supply voltages, the power supply voltage supplied from the external power supply to the pachinko machine 1 is converted into a predetermined power supply voltage on the power supply board, Supplying to the device. Thus, when a power failure occurs and the power supply voltage supplied from the external power supply to the power supply board becomes equal to or lower than the predetermined power supply voltage, a power failure notice signal indicating that the supply of the power supply voltage from the power supply board to the main control board 101 is stopped. Sent. Then, when a power failure notice signal is detected by the CPU 102 mounted on the main control board 101 in step S2, a process at the time of power failure occurrence is executed (step S4). This power-off process is performed when the power supply voltage supplied to the power supply board after a power failure is restored (24V in this embodiment) (hereinafter referred to as power recovery), and the operation of the gaming machine is in a state before the power failure. This is a process of storing the state at the time of the occurrence of a power failure as backup data in the RAM 104 in order to start from. Although the processing content will be described later, in the present embodiment, as shown in the figure, the power failure occurrence processing is not interrupt processing, but as branch processing that is executed immediately after the start of the loop depending on whether or not a power failure warning signal is detected. It is incorporated in the main process (main control process).

  When the power failure warning signal is not detected in step S2, that is, when the power from the external power supply is normally supplied, the random number update process 2 for updating various random numbers used in the game is performed (step S3). . The random number updated in the random number update process 2 will be described later.

  FIG. 12 is a flowchart showing an example of the process at the time of power-off occurrence (step S4). As described above, the power-off occurrence process is a process executed when a power failure warning signal is detected in the main process. First, the CPU 102 performs an interrupt prohibition setting so that the interrupt process is not executed (step S4a). Then, the checksum of the RAM 104 is calculated and stored in a predetermined area of the RAM 104 (step S4b). This checksum is used to check whether or not the contents of the RAM 104 before the power failure is retained at the time of power recovery.

  Next, the CPU 102 sets a specified value indicating that the process at the time of power-off occurrence has been performed in a backup flag provided in a predetermined area of the RAM 104 (step S4c). When the above processing is completed, the CPU 102 prohibits access to the RAM 104 (step S4d) and enters an infinite loop to prepare for the stop of power supply. In this process, if the power supply voltage becomes unstable due to a very short power failure, etc. (hereinafter referred to as “instantaneous power interruption”), the process at the time of the occurrence of power interruption has started. Since the power supply voltage is not stopped, there is a possibility that the process described above cannot return from the infinite loop. In order to avoid such an adverse effect, the CPU 102 of this embodiment is provided with a watchdog timer, and is configured to be reset if the watchdog timer is not updated for a predetermined time. The watchdog timer is periodically updated while the process is normally performed. However, the watchdog timer enters the process when the power is cut off and is not updated. As a result, even when the power interruption occurs due to a momentary power failure and the infinite loop of FIG. 12 is entered, a reset is applied after a predetermined period of time, and the CPU 102 is started in the same process as when the power is turned on.

  FIG. 13 is a flowchart illustrating an example of timer interrupt processing. As described above, in this embodiment, the timer interrupt process is executed every 4 ms by the CPU 102 mounted on the main control board 101 during the execution of the main process. In the timer interrupt process, the CPU 102 executes the process from step S11 to step S19 after executing the register saving process (step S10). In the switch input process of step S11, a process of monitoring the detection signals of the above-described switches (gate switch 49, start port switch 46, count switch 64, etc.) is executed. In the payout operation process in step S12, a payout command for instructing payout of the game ball is transmitted to the payout board 105 based on the signal detected in the switch input process (step S11). In the random number update process 1 in step S13, a process of updating various random numbers used in the game is executed. In this embodiment, the random number updated in the random number update process 1 is different from the random number updated in the random number update process 2 described above. Although the random number will be described later, the random number updated in the random number update process 2 may be updated in the random number update process 1 as well.

  Moreover, in the game process of step S14, the process which controls the pachinko machine 1 according to the progress state of a game is performed. In the normal symbol game of step S15, control processing related to the normal symbol display LED 43 is executed. In the ordinary electric game at step S16, processing for opening / closing control of the opening / closing pieces 73, 74 is executed. In the special symbol game of step S17, control is executed to display the special symbol display LED 41 in a variable manner based on the result of the game process (step S14). In the special electric accessory game of step S18, the opening / closing control of the opening / closing plate 62 is executed by movably controlling the special winning opening solenoid 63. In the command transmission output process of step S19, a process of transmitting the effect command set in the game process (step S14) to the sub-integrated board 111 is executed. In the command transmission output process (step S19), a process for transmitting the power-on command set in the power-on process (step S1) to the sub-integrated board 111 when power supply to the pachinko machine 1 is started. Done. In the I / O port output process of step S20, a process of outputting a state signal indicating a gaming state to the outside of the pachinko machine 1 (for example, a management computer), a process of outputting a drive signal to the special figure start memory lamp 147, etc. Execute. When the processing from step S11 to step S20 is executed, the register restoration processing (step S21) is executed, and the processing is terminated.

  Here, various random numbers updated by the CPU 102 mounted on the main control board 101 in the above-described random number update process 1 (step S13) and random number update process 2 (step S3) will be described with reference to FIG. As shown in FIG. 14, in this embodiment, as various random numbers used in the game, a big hit determination random number used for determining whether or not to generate a big hit gaming state (big hit determination), a big hit gaming state in the big hit determination Is a probability variation determination random number used to determine whether or not to make a probability variation big hit (probability variation determination) when it is determined that a big hit gaming state is not to be generated in the big hit determination, it is out of reach with a reach mode Reach determination random number used for determination (reach determination), variation display pattern random number used to determine the variation display pattern of the special symbol displayed on the special symbol display LED 41, the start winning opening 72 Normal random number per random symbol (random number extraction means) used for determining whether or not the open / close pieces 73 and 74 are controlled to be in an open state (normal symbol per unit determination) Shift determining means), and the like. Note that the variable display pattern of the special symbol may be determined using the reach determination random number, and the variable display pattern of the decorative symbol controlled by the liquid crystal display 42 may be determined.

  Among these random numbers, in the random number update process 1, the big hit determination random number related to the occurrence of the big hit gaming state, the probability variation determination random number, and the normal related to whether or not the open / close pieces 73 and 74 of the start winning opening 72 are controlled to the open state. Update the random number for each symbol. That is, the random numbers used for the determination relating to the occurrence of the big hit gaming state and whether or not to control the open / close plate 62 of the condition operating device (big prize opening device 60) to the open state are updated every 4 ms as a predetermined timing. By doing so, the probability (probability to determine that the big hit gaming state is generated, probability to determine to control the open / close plate 62 of the condition operating device to be in the open state) in each random number in a predetermined period can be made constant. It is possible to prevent the player from being disadvantaged. On the other hand, in the random number update process 2, the reach determination random number and the variable display pattern random number are updated regardless of the occurrence of the big hit gaming state and the display result of the normal symbol. Note that the random numbers updated on the main control board 101 are not limited to those described above, and in the random number update process 2, the initial of the big hit determination random number that starts counting next when the counter that updates the big hit determination random number makes one round. The initial value determination random number for determining the value is also updated.

  FIG. 15 is a flowchart showing an example of the game process (step S14). In the game control process, the CPU 102 first determines whether or not a game ball has won the start winning opening 72 (step S30). Specifically, it is determined whether or not a detection signal is output from the start port switch 46. If a detection signal is output from the start port switch 46, a game ball is won in the start winning port 72 (in step S30). YES), and if no detection signal is output from the start port switch 46, it is determined that no game ball has been won in the start winning port 72 (NO in step S30). When it is determined in step S30 that a game ball has won the start winning opening 72, various random numbers (a big hit determination random number, a probability variation determination random number, etc.) are acquired, and the value of the reserved ball number counter provided in the RAM 104 is the upper limit. It is determined whether or not the value is less than 4 (step S31). If the held ball number counter is less than 4 in step S31, start memory storage processing is performed (step S32). When the start port switch 46 is not turned on at step S30 and when the value of the held ball number counter is 4 at step S31, the start storage storing process is not executed. Thereafter, the CPU 102 refers to the value of the process selection flag indicating the progress of the game, and performs any one of steps S40 to S44.

  In the start memory storing process, a process of adding “1” to the held ball number counter and a process of changing the lighting display mode (the number of LEDs to be turned on) of the special figure start memory LED 68 in accordance with the addition of the held ball number counter. And a process of storing the acquired random number value (in this embodiment, the big hit determination random number, the probability variation determination random number) in the storage area of the start memory provided in the RAM 104 in correspondence with the count value of the reserved ball number counter. Do. Thus, the reserved ball number counter is a counter indicating the number of random numbers stored in the storage area of the start memory. If the value of the reserved ball number counter is the upper limit value in step S31, the random number value acquired in step S30 is discarded. When it is determined in step S30 that the game ball has won the start winning opening 72, various random numbers may be acquired between step S30 and step S32. For example, the various random numbers are not acquired in step S30. After determining that the reserved ball number counter is less than the upper limit value in S31, various random numbers may be acquired, or may be acquired in the start storage storage process (step S32).

  In the variation start process (step S40) executed when the process selection flag is “0”, the start memory number is confirmed. If the start memory number is not 0, the setting for starting the variation display of the special symbol is made. Do. As will be described in detail later, specifically, it is determined whether or not a big hit gaming state is to be generated, and if a big hit gaming state is to be generated, it is determined whether or not to be a promising big hit. In the variable display pattern setting process (step S41) executed when the process selection flag is “1”, settings related to the special symbol and decorative pattern variable display are performed. Specifically, although the details will be described later, the variation display pattern of the special symbol is determined, and the variation time set corresponding to the variation display pattern (after the variation display of the special symbol is started by the special symbol display LED 41) Set the timer until the stop display). In the changing process (step S42) executed when the process selection flag is “2”, the timer set with the changing time in the changing display pattern setting process (step S41) is monitored, and the timer has timed out. Then, the special symbol display LED 41 performs processing for stopping the variation display of the special symbol. At this time, if it is determined that the big hit gaming state is made in the variation start process (step S40), the process selection flag is updated to “3”, and if it is not judged that the big hit gaming state is made, the process selection flag is set. Update to “0”.

  Further, in the big hit game start process (step S43: profit grant state control means) executed when the process selection flag is “3”, a setting for starting the big hit game state is performed. Specifically, a jackpot start command for instructing execution of the start display of the jackpot gaming state is transmitted to the sub-integrated board 111, and the number of times of opening the condition operating device is set.

  In the big hit game processing executed when the process selection flag is “4” (step S44: profit granting state control means), the number of game balls detected by the count switch 64 when the big hit gaming state is started. When a predetermined number (9 in this embodiment) of game balls wins the big prize opening 62 or when a predetermined period (30 seconds in this embodiment) elapses, the condition actuating device In addition to performing a process for putting the game in the closed state (execution period limiting means), the sub-integrated board 111 transmits a jackpot command that instructs execution of a display in the jackpot gaming state (for example, round display). Also, if the number of rounds in the big hit gaming state has not reached the predetermined number (15 in this embodiment), the processing for opening the conditional operation device is performed again, and the number of rounds in the big hit gaming state is When the predetermined number of times is reached, a jackpot end command is sent to the sub-integrated board 111 to instruct execution of a jackpot gaming state end display, and the processing selection flag is updated to “0”.

  FIG. 16 is a flowchart illustrating an example of the variation start process (step S40). In the variation start process, the CPU 102 determines whether or not the value of the reserved ball number counter is 0 (step S401). As described above, since the value of the held ball number counter indicates the number of random numbers stored in the start memory storage area, if the value of the held ball number counter is 0 in step S401, the start memory is stored. It is determined that there is not, and the process is terminated.

  On the other hand, if the value of the reserved ball number counter is not 0 in step S401, a start memory transfer process is executed (step S402). In the start memory transfer process, the process of subtracting 1 from the reserved ball number counter, and after shifting various random numbers stored in the start memory storage area provided in the RAM 104, the start ball storage counter of the start memory storage area A process of reading various random numbers (such as jackpot determination random numbers) stored in the storage area corresponding to 0 is performed. Specifically, various random numbers stored in the storage area corresponding to n (n = 1, 2, 3, 4) of the reserved ball number counter in the storage area of the start memory are stored in the storage area of the start memory. The number is stored in a storage area corresponding to n-1 (n = 0, 1, 2, 3) of the number counter.

  Next, in step S402, it is determined whether or not to generate a big hit gaming state using the big hit determination random number read from the storage area corresponding to 0 of the reserved ball number counter among the storage areas of the reserved memory, and the big hit gaming state is determined. In the case of generating, after the big hit determination process for determining whether or not the probability variation big hit is made (step S403), the process selection flag is updated to “1” (step S404). By updating the process selection flag to “1”, the timer interrupt process occurs next, and the variable display pattern setting process (step S41) can be executed when the game process (step S14) is executed.

  FIG. 17 is a flowchart illustrating an example of the big hit determination process (step S404). In the big hit determination process, the CPU 102 determines whether or not the probability variation flag set in the big hit game process (step S44) is in an ON state (set) (step S51). If the probability variation flag is ON, a probability variation state big hit determination table (not shown) is selected (step S52: high probability state control means), and if the probability variation state flag is not ON (if it is OFF), A big hit determination table (not shown) in the normal / short time state is selected (step S53: normal state control means). In the promiscuous state jackpot determination table, 14 jackpot determination values that are determined to generate a jackpot gaming state by matching the jackpot determination random number among 980 jackpot determination random numbers from 0 to 979 are set. The jackpot probability, which is the probability of a jackpot, is 1/70. On the other hand, in the normal / short time state big hit determination table, two big hit determination values are set out of 980 big hit determination random numbers from 0 to 979, and the big hit probability is 1/490.

  Then, the determination value set in the probability change state big hit determination table selected in steps S52 and S53, or the normal / short-time state big hit determination table, and the value of the big hit determination random number read out in the start memory transfer process in step S402 And whether or not to generate a big hit gaming state is determined (step S54). The determination value set in the probability change state big hit determination table selected in steps S52 and S53, or the normal / short-time state big hit determination table, and the value of the big hit determination random number read in the start memory transfer process in step S402 (hold) The jackpot flag is set to ON when it is determined that a jackpot gaming state is to be generated based on a match with the value of the jackpot determination random number stored in the storage area corresponding to 0 of the ball counter. Later (step S55), it is determined based on a probability variation determination table (not shown) in which a predetermined criterion value is set whether or not the probability variation big hit is made (step S56: high probability state determination means). Specifically, it is set in the probability variation determination table and the value of the probability variation determination random number read in the start memory transition process in step S402 (value of the probability variation determination random number stored in the storage area corresponding to 0 of the reserved ball number counter). It is determined whether or not to be a probable big hit based on whether or not the determination value matches. In the present embodiment, the probability variation entry rate (the ratio of the probability variation to the probability variation big hit) is 2/3, that is, the probability variation big hit among the nine probability variation determination random numbers from 0 to 8. Six determination values to be determined are set in the probability variation determination table.

  If it is determined in step S56 that the determination value set in the probability variation determination table and the value of the probability variation determination random number read in the start memory transfer process in step S402 match, the probability variation state is determined. The flag is turned on (set) (step S57). On the other hand, when it is determined in step S54 that a big hit is not made (deviated) and in step S56, it is decided that a probability variation big hit is not made (non-probable variation big hit), the following processing is executed. The process ends without The ON / OFF state (set state, reset state) of the big hit flag and the probability variation state flag is stored in the RAM 104. The OFF state (reset state) of the big hit flag and the probability change state flag is a value of “0”, and the ON state (set state) of the big hit flag and the probability change state flag is a value of “1”. Is set.

  Note that the big hit flag is a flag indicating control for shifting to the big hit gaming state. If the big hit flag is set in the big hit game start process (step S43), the big hit gaming state is generated. The probability change state flag is a flag indicating the transition control to the probability variation state after the big hit gaming state is finished, and the probability change state flag is set when the big hit gaming state is ended in the big hit gaming process (step S44). Then, the process of resetting the probability variation state flag and setting the probability variation flag indicating the probability variation state is executed. In the state in which the probability variation flag is set, the probability variation state is controlled as described above. For example, the probability variation state big hit determination table in step S52 described above is selected and the state other than the probability variation state (normal state, time reduction state). The probability of determining that a big hit gaming state is to be generated is increased. If the probability variation flag is set in the big hit game start processing (step S43), processing for resetting the probability variation flag is executed.

  FIG. 18 is a flowchart illustrating an example of the variable display pattern setting process (step S41). In the variable display pattern setting process, the CPU 102 determines whether or not a big hit is made as a result of the present variable display, that is, whether or not the big hit flag is set (step S410), and the big hit flag is set. If it is ON (if it is in the ON state), the big hit time fluctuation display pattern table (see FIG. 19) in which the fluctuation display pattern used when the big hit is set is selected (step S412). If the big hit flag is not set (if it is OFF), a reach determination random number is acquired and stored in a predetermined storage area of the RAM 104 and set in a reach determination table in which a predetermined determination value is set. It is determined whether or not the reach is determined based on whether or not the determined determination value matches the value of the acquired reach determination random number (step S411). When it is determined that the reach mode is selected, a reach-time variation display pattern table (see FIG. 19) in which a variation display pattern showing a mode for deriving an outlier symbol with a reach mode is set is selected (step S413), and reach is performed. When it is determined not to be an aspect, the detachment fluctuation display pattern table (see FIG. 19) in which a fluctuation display pattern showing an aspect for deriving a losing symbol without a reach aspect is set is selected (step S414). In the reach determination table, the reach probability (reach mode ratio) is 1 / 12.5, that is, two determination values out of 25 reach determination random numbers from 0 to 24 are reach determination. Set in the table.

  Then, the variable display pattern random number is acquired and stored in a predetermined storage area of the RAM 104, and the big hit time variable display pattern table, the reach variable display pattern table selected in Steps S411, S413, and S414 are displayed. The variation display pattern in which the determination value set in any one variation display pattern table of the table matches the value of the acquired variation display pattern random number is determined (step S415).

  The deviation fluctuation display pattern table includes a table in which only a fluctuation display pattern of “normal fluctuation” of fluctuation number 1 described later is set, a table in which only a fluctuation display pattern of “shortening fluctuation” in fluctuation number 2 is set, When the above-mentioned time-shortening control is not executed, a table in which only the fluctuation display pattern of “normal fluctuation” with the fluctuation number 1 is set is selected. A table in which only the variation display pattern of “shortening variation” of No. 2 is set is selected. That is, when the time reduction control is not executed, the fluctuation display pattern of “normal fluctuation” with the fluctuation number 1 is determined, and when the time reduction control is executed, the fluctuation of the “shortening fluctuation” with the fluctuation number 2 is determined. The display pattern is determined. Further, the variation display pattern (table) of variation number 2 of “shortening variation” is a jackpot determination random number extracted based on the detection by the start port switch 46 even when the time reduction control is not executed. The stored ball number counter indicating the stored number can be selected when any one of the conditions such as the upper limit value and the probability variation state is satisfied.

  Next, a variation display pattern command is set as an effect command for designating the variation display pattern determined in step S415 (step S416), and a variation time corresponding to the variation display pattern is provided in the RAM 104 mounted on the main control board 101. Is set to a timer (in this embodiment, a valid period timer) (step S417). In step S417, the variation time set in the variation display pattern determined in step S415 is set in the effective period timer. Note that the variable display pattern command set in step S416 is transmitted to the sub-integrated board 111 in the command transmission output process (step S19). Further, when a variable display pattern command is transmitted to the sub-integrated board 111 by command transmission output processing, a drive signal is output to the special symbol display LED 41 in a special symbol game to start the variable symbol variable display.

  Here, the fluctuation display pattern command is data of 2 bytes, and the fluctuation display of the special symbol is stopped and displayed in each fluctuation display pattern command after the special symbol display LED 41 starts the fluctuation display of the special symbol. Data for specifying the fluctuation time and reach production to be included. Of the 2-byte variable display pattern command, the first byte is data that can specify a variable display pattern, and the second byte is data that can specify a variable number (variable display pattern). . That is, the integrated CPU 112 mounted on the sub-integrated board 111 can recognize the variable display pattern based on the first byte data, and further specifies the variable display pattern based on the second byte data. .

  The variable display pattern determined in step S415 will be described with reference to FIG. FIG. 19 is a list showing an example of the variable display pattern. The liquid crystal display 42 follows the variation display pattern during the special symbol variation time (the time from when the special symbol variation display is started by the special symbol display LED 41 until the special symbol variation display is stopped). The effect mode is displayed as an image.

  The “normal fluctuation” of the fluctuation number 1 is a fluctuation display pattern without a reach mode. The variation number 2 “shortening variation” is a variation display pattern in which the variation time of the special symbol and the decorative symbol is shorter than the “normal variation”. The “normal reach” of the variation numbers 3 and 4 is a variation display pattern for executing a normal reach effect with a reach mode. The “normal reach (long)” of the variation numbers 5 and 6 is a variation display pattern in which the normal reach production is executed continuously after the execution of the normal reach production similar to the variation numbers 3 and 4 with the reach mode. That is, “normal reach (long)” is a variation pattern in which the execution period of the normal reach effect is set longer than that of “normal reach”.

  Further, the “first super reach” of the variation numbers 7 and 8 is a variation display pattern for executing the first super reach effect with the reach mode. “First Super Reach (Long)” with variation numbers 9 and 10 means that the first super reach production is executed after the execution of the first super reach production similar to the variation numbers 7 and 8 with the reach mode. This is a variable display pattern. The “second super reach” of the variation numbers 11 and 12 is a variation display pattern for executing the second super reach effect with the reach mode. The “second super reach (long)” of the variable numbers 13 and 14 means that the second super reach effect is developed after the execution of the second super reach effect similar to the variable numbers 11 and 12 with the reach mode. This is a variable display pattern.

  In addition, for each variation display pattern, a variation time of a special symbol (the time from when the variation display of the special symbol is stopped by the special symbol display LED 41 until the variation display of the special symbol is stopped) is set. Yes. The variation time of the special symbol is set to substantially coincide with the variation time of the decorative symbol designated by the variation display pattern command transmitted to the sub-integrated board 111. In step S415, the variation corresponding to the variation time of the special symbol is set. The variation display pattern having the symbol variation time is determined. In other words, the variation time of the special symbol and the variation time of the decorative symbol do not have to completely match.

  Specifically, the variation time of the special symbol in which the reach effect is not executed is set such that “normal variation” of variation number 1 is set to 6 s and “shortening variation” of variation number 2 is set to 3 s. On the other hand, the variation time of the special symbol for executing the reach effect is “normal reach” with variation numbers 3 and 4, “first super reach” with variation numbers 7 and 8, and “second super reach” with variation numbers 11 and 12. Set to 30 s, “normal reach (long)” with variable numbers 5 and 6, “first super reach (long)” with variable numbers 9 and 10, and “second super reach (long)” with variable numbers 13 and 14 Is set to 60 s. That is, the reach effect that does not become long (continuation or development) in the variation time of the special symbol for executing the reach effect is set to 30 s uniformly, and the long (continuation or development) in the variation time of the special symbol for executing the reach effect. The reach effect is set to 60s uniformly.

  Further, in the variation display patterns of variation numbers 3 to 14, the reach effect is executed in the same or similar effect mode at the time of the big hit and out of time according to the result of the win, and a special symbol corresponding to the reach effect and Since the variation time of the decorative symbols is set to be substantially the same, it is difficult to recognize whether or not it is just by looking at the production, the player can be thrilled, and the interest of the game is not reduced.

  In this embodiment, the big hit hour fluctuation display pattern table selected in step S411 includes a fluctuation display pattern (fluctuation display pattern shown in FIG. 19) in which the winning result is a big hit among the fluctuation display patterns of fluctuation numbers 3 to 14. Fluctuation display patterns marked with a circle in the table win are set, and the judgment values are assigned to these fluctuation display patterns. In addition, the reach variation display pattern table selected in step S413 includes a variation display pattern in which the winning result is out of the variation display patterns of the variation numbers 3 to 14 (in the variation display pattern table shown in FIG. 19). Variation display patterns) are set, and determination values are distributed to these variation display patterns.

  In addition, the table selected when the above-mentioned time-shortening control is not executed among the variation display pattern tables at the time of loss is a determination value for the variation display pattern of “normal variation” with variation number 1 that results in a loss of the winning result. The table selected when the time-shortening control is executed among the variation display pattern tables at the time of loss is included in the variation display pattern of the “shortening variation” of variation number 2 in which the result of the win is lost. Judgment values are distributed.

  In addition, in the big hit fluctuation display pattern table and the reach deviation fluctuation display pattern table, the big hit expectation degree (the ratio of the big hit in the ratio (the total appearance rate) in which the reach presentation is executed (total appearance rate)) Appearance rate at the time); expectation value of jackpot = appearance rate at the time of jackpot / total appearance rate) The determination values are assigned to the respective variable display patterns. Specifically, “normal reach” of variation numbers 3 and 4, “normal reach (long)” of variation numbers 5 and 6, “first super reach” of variation numbers 7 and 8, “second reach” of variation numbers 11 and 12 The jackpot expectation is set to increase in the order of “super reach”, “first super reach (long)” with variable numbers 9 and 10, and “second super reach (long)” with variable numbers 13 and 14. .

  Subsequent to step S417 of the variation display pattern setting process, the CPU 102 checks whether or not the probability variation state flag is set (step S418). The probability variation jackpot command is set (step S419). Then, the process selection flag is updated to “2” (step S420). Note that the probability variation jackpot command set in step S419 is transmitted to the sub-integrated board 111 in the command transmission output process (step S19) together with the variation display pattern command. As a result, the integrated CPU 112 mounted on the sub-integrated board 111 can recognize that the current variation display results in a probable big hit.

  In the variable display pattern setting process, whether or not the big hit flag and the probable change status flag are set in addition to the probable big hit command as an effect command indicating the winning result is confirmed, the big hit flag is set. A process of setting a winning command indicating an uncertain change big hit when the status flag is not set and a winning command indicating a deviation when the big hit flag is not set is executed. The integrated CPU 112 mounted on the sub-integrated board 111 can recognize that the current variable display results in an uncertain change big hit based on the winning command transmitted together with the variable display pattern command. In this embodiment, the variable display pattern command also includes information indicating the result of the winning, and the integrated CPU 112 determines whether or not the winning results indicated by the variable display pattern command and the winning command match. ing. As a result, the integrated CPU 112 can reliably recognize the result of the current fluctuation display, and prevent a malfunction such as failure to receive a command due to the influence of external noise or the like, and displaying an incorrect fluctuation display result. Can do.

  Further, in the variation display pattern setting process, it is confirmed whether or not the probability variation flag or the time reduction flag is set as an effect command indicating the gaming state, and the gaming state is the probability variation state when the probability variation flag is set. A process for setting a game state command indicating the game state command indicating that the game state is the time-short state when the time-short flag is set is executed. The gaming state command is transmitted to the sub-integrated board 111 in the command transmission output process (step S19) together with the change display pattern command and the winning command. The integrated CPU 112 mounted on the sub-integrated board 111 can recognize that the gaming state is a probability changing state by the gaming state command indicating the probability changing state, and the gaming state is the time saving state by indicating the time shortening state. I can recognize that.

  Note that the hourly flag is a flag that is set when it is determined in step S56 of the big hit determination process that the probability change big hit is not set (non-probable change big hit is determined), and the big hit gaming state is set in the big hit game processing (step S44). Processing to be set when ending is executed. When the time reduction flag is set, the time is controlled to the time reduction state. For example, in step S414, the variation time 2 of the variation number 2 in which the variation time of the special symbol is shortened from the normal state from the variation variation display pattern table at the time of deviation. A variable display pattern is selected. Further, when it is determined that the next big hit gaming state is to be generated in step S54 of the big hit determination process until the predetermined number of special symbol fluctuation display is executed after the big hit gaming state ends, or after the big hit gaming state ends. In the case where the variable display of the special symbol of the number of times is executed, a process for resetting the time reduction flag is executed. Note that the ON / OFF state (set state, reset state) of the time reduction flag is stored in the RAM 104. Further, the OFF state (reset state) of the time reduction flag means that a value of “0” is set, and the ON state (set state) of the time reduction flag means that a value of “1” is set.

  The effective period timer set with the variation time in step S417 starts when the variation display pattern command is transmitted to the sub-integrated board 111 in the command transmission output process (step S19), and in the variation process (step S42). When the effective period timer times out, a special signal display LED 41 is output to drive the special symbol to be stopped by the CPU 102, and the sub-integrated board 111 is instructed to stop displaying the decorative symbol. Stop command). The sub-integrated board 111 performs control for confirming and displaying the stop of the decorative symbol based on the reception of the change stop command.

  In addition, when a plurality of display areas are provided on the display device and symbols are displayed in a variable manner in each display area, the display is stopped at a specific display result when the big hit determination process is performed. When there are multiple display lines to be displayed, when a symbol that has not been stopped on any display line stops at a predetermined symbol, the symbol that is stopped and displayed on the display line becomes a specific display result. Alternatively, a state in which all symbols are variably displayed in a combination such that a specific display result is obtained on any one of the display lines is referred to as a reach mode. In other words, the reach mode is a mode (a mode just before a big hit) representing a step before a specific display result (big hit display). In this embodiment, there is only one display line as described above, and among the left, middle and right decorative symbols displayed on the liquid crystal display 42, the left decorative symbol and the right decorative symbol (any two decorative symbols). May be combined), and the medium decorative symbol (the remaining decorative symbol when the combination of two arbitrary decorative symbols is stopped) is displayed in a variable manner, or the liquid crystal display 42 All the decorative symbols displayed on the screen are displayed in a synchronized manner with the same symbol combination (for example, the left, middle, and right decorative symbols are displayed in a synchronized manner so that they always have the same design. State) is called a reach mode. After the reach mode is reached, an effect (for example, the frame lamp 27) executed by the frame lamp 27, the side lamp 65, the liquid crystal display 42, the upper speaker 36, the lower speaker 14, and the like. Lighting or blinking a side lamp 65 in a predetermined manner, a predetermined image displayed on the liquid crystal display 42, a predetermined voice output at the upper speaker 36, and lower speaker 14) of the reach demonstration.

  Next, processing executed by the integrated CPU 112 mounted on the sub integrated substrate 111 will be described. FIG. 20 is a flowchart showing an example of sub-main processing, and FIG. 21 is a flowchart showing an example of 16 ms steady processing.

  As shown in FIG. 20, when power supply to the pachinko machine 1 is started, the integrated CPU 112 performs an initial setting process (step S71). In the initial setting process, a process of clearing the integrated RAM 114 mounted on the sub-integrated board 111 is performed. Note that interrupts are prohibited during this initial setting process, and interrupts are permitted after the initial setting process. When the initial setting process (step S71) ends, a loop process for monitoring whether or not the 16 ms elapsed flag T is set is started (step S72).

  In this embodiment, the integrated CPU 112 generates an interrupt every 2 ms and executes a 2 ms steady process. In the 2 ms steady process, a process of counting up the 16 ms progress monitoring counter (adding 1 to the 16 ms progress monitoring counter) is executed, and when the value of the 16 ms progress monitoring counter reaches 8, that is, 16 ms elapses. While the flag T is set, a 16 ms progress monitoring counter is reset (set to 0). In this way, the 16 ms elapsed flag T is set (set) to “1” every 16 ms in the 2 ms steady process, and is normally set (reset) to “0”. If the 16 ms elapsed flag is set in step S72 (the 16 ms elapsed flag T is “1”), the 16 ms elapsed flag is reset (step S73), and then the 16 ms steady process is performed (step S74).

  In this 16 ms steady process, a process of controlling the liquid crystal display 42, the frame lamp 27, the side lamp 65, the speakers 14, 36, etc. based on the effect command received from the main control board 101 is executed. When the 16 ms steady process ends, the process returns to step S72 again, and every time the 16 ms elapse flag T is set, that is, every 16 ms, step S73 to step S74 described above are repeated. On the other hand, if the 16 ms elapsed flag T is not set in step S72 (the 16 ms elapsed flag T is “0”), the loop processing is performed until the 16 ms elapsed flag T is set.

  FIG. 21 is a flowchart showing an example of a 16 ms steady process executed every 16 ms in the sub main process. In the 16 ms steady process, the integrated CPU 112 executes the processes of steps S91 to S95. In the command analysis process of step S91, the effect command received from the main control board 101 is analyzed. In the effect control process of step S92, a control process related to the liquid crystal display 42 is executed based on the variable display pattern command. More specifically, a stop symbol for a decorative symbol, which will be described later, is determined.

  Moreover, in the sound control process of step S93, the control process regarding the speakers 14 and 36 is performed. In the lamp control process in step S94, control processes related to the side lamp 65 and the frame lamp 27 are executed. In the information output process in step S95, a display command is transmitted to the display control board 220, and a drive signal and a lamp lighting signal are transmitted to the lamp drive board 156. In the random number update process of step S96, a process of updating random numbers used for various settings in the effect control process (step S92) is executed.

  Here, various random numbers updated by the integrated CPU 112 mounted on the sub-integrated board 111 in the random number update process (step S96) described above will be described with reference to FIG. As shown in FIG. 22, in this embodiment, a probabilistic jackpot symbol random number used to determine a probable big hit symbol as a decorative symbol stop symbol, and a non-probable big jackpot used to determine a non-probable big jackpot symbol as a decorative symbol stop symbol. Examples of the symbol random number and the stop symbol of the decorative symbol include a symbol random number used for determination of the symbol offset. It should be noted that various random numbers (probability big hit symbol random number, non-probable big hit symbol random number, outlier symbol random number, etc.) are used when the effect command received from the main control board 101 in the command analysis process (step S91) is a variable display pattern. To be acquired.

  In addition, the processes in steps S91 to S96 in the 16 ms steady process are completed within 16 ms. Even if it takes 16 ms or more from the start of the 16 ms steady processing to the end of the 16 ms steady processing, the 16 ms steady processing is started from the beginning immediately after the 16 ms has elapsed since the start of the 16 ms steady processing (step S91 described later). Do not execute) That is, when 16 ms elapses during execution of the 16 ms steady process, only the 16 ms elapse flag is set, and when it is determined in step S72 that the 16 ms elapse flag is set after the end of the 16 ms steady process, the 16 ms steady process is performed. To start.

  In this embodiment, the random number update process (step S96) is executed in the 16 ms steady process to update various random numbers. However, the timing (timing) for updating the various random numbers is limited to this. It is not something that can be done. For example, various random numbers may be updated in one or both of the loop processing in the sub-main processing and the 16 ms steady processing.

  FIG. 23 is a flowchart illustrating an example of the command analysis process (step S91). In the command analysis process, the integrated CPU 112 first determines whether or not an effect command has been received from the main control board 101 (step S601). In this embodiment, when an effect command is received from the main control board 101, other processes such as a 16 ms steady process are interrupted to generate a command reception interrupt process, and the received command is mounted on the sub-integrated board 111. Are stored in the received command storage area in the integrated RAM 114. The reception command storage area is provided with a plurality of areas corresponding to the reception order of the production commands, and in the command reception interrupt process, the reception command storage areas are stored in the respective areas corresponding to the reception order of the production commands. In step S601, the contents of the received command storage area are confirmed. If the received command is stored, the effect command in the order of reception in the received command storage area is read (step S602).

  Then, it is determined whether or not the read effect command is a variable display pattern command (step S603). If the read effect command is a variable display pattern command (YES in step S603), a variable display pattern reception flag is set. Then, it is stored in the variable display pattern storage area in the integrated RAM 114 mounted on the sub-integrated board 111 (step S604).

  On the other hand, if the read effect command is not a variable display pattern command (NO in step S603), it is determined whether the read effect command is a probability change jackpot command (step S605), and if the read effect command is a probability change jackpot command. If (YES in step S605), the probability variation jackpot flag is set (step S606). Also, if the read effect command is not a probability change jackpot command (NO in step S605), it corresponds to the received effect command (a winning command other than the probability change jackpot command, a gaming state command, a variable stop command, a jackpot start command, etc.). A flag is set (step S607).

  FIG. 24 is a flowchart illustrating an example of the effect control process (step S92). In the effect control process, the integrated CPU 112 performs any one of steps S700 to S702 with reference to the value of the process selection flag indicating the progress state of the game.

  In the decorative symbol variation start process (step S700) executed when the process selection flag is “0”, a setting for starting the decorative symbol variation display is performed if a variation display pattern command is received. More specifically, the decoration design stop symbol is determined according to the variable display pattern command and the probability variation jackpot command, and the reach effecting mode is determined, and the process selection flag is updated to “1”.

  In the decorative symbol variation process (step S701) executed when the processing selection flag is “1”, when the variation stop command is received, a display command is transmitted to the display control board 220 to stop the decorative symbol variation display. When the control is performed and the big hit start command is received from the main control board 101, the processing selection flag is updated to “2”, and when the big hit start command is not received from the main control board 101, the processing selection flag is set to “0”. Update to

  In the jackpot display process (step S702) executed when the process selection flag is “2”, a display indicating the start of the jackpot gaming state is displayed on the liquid crystal display 42 in accordance with the jackpot start command transmitted from the main control board 101. And performing control for displaying a big hit game state (for example, round display) in response to a big hit game command transmitted from the main control board 101, and receiving a big hit end command, the big hit game The end of the state is displayed and the process selection flag is updated to “0”.

  FIG. 25 is a flowchart showing an example of the decorative symbol variation start process (step S700). In the decorative symbol variation start process, the integrated CPU 112 first determines whether or not the variation display pattern reception flag is set (step S710). The variation display pattern reception flag is a flag that is set in step S604 of the command analysis process (step S91) described above and indicates that a variation display pattern command has been received from the main control board 101. That is, if the variation display pattern reception flag is not set in step S710 (NO in step S710), it is determined that the variation display pattern command has not been received, and the decorative symbol variation start process is terminated.

  On the other hand, if the variable display pattern reception flag is set (YES in step S710), the variable display pattern reception flag is reset (step S711), and it is determined whether the received winning command is a command indicating a win. It is determined whether the variation display pattern based on the received variation display pattern command is a variation display pattern that generates a big hit (whether it is a winning pattern) (step S712). Whether or not the pattern is a hit pattern can be confirmed by referring to the second byte data of the variable display pattern command.

  If the winning command is not a command indicating a win (NO in step S712), a stop symbol of the missed symbol is determined (step S713). If the variation display pattern is a hit pattern (YES in step S712), it is determined whether the probability variation big hit flag is set (step S714). If the probability change big hit flag is set (YES in step S714). Then, the stop symbol of the probability variation big hit symbol is determined (step S715).

  On the other hand, if the probability variation big hit flag is not set in step S714 (NO in step S714), the stop symbol of the non-probable big hit symbol is determined (step S716). The probability variation big hit flag is reset when the big hit gaming state is started in the big hit display process (step S702). The time when the probability variation jackpot flag is reset is not limited to this. For example, when the variation display of the decorative symbol is stopped in the decorative symbol variation processing (step S701), specifically, when the variation stop command is received. It may be reset, or may be reset when the big hit gaming state is ended in the big hit display process (step S702).

  In this embodiment, a combination symbol is determined as a stop symbol from the combination of odd odd symbols (specific symbols) that is the same as the odd variation of the decorative symbol, and the same even symbol as the non-probable large bonus symbol of the decorative symbol. One of the combinations of (non-specific symbols) is determined as a stop symbol. In step S713, when the stop symbol of the shift symbol is determined, it is determined whether it is a variable display pattern with a reach mode. If the variable display pattern has a reach mode, the left, middle, and right decorative symbols are displayed. Among them, the left and right decorative symbols are the same symbol, and the middle decorative symbol is determined as a stop symbol that is different from the left and right decorative symbols. On the other hand, if it is a variable display pattern not accompanied by a reach mode, the left, middle, and right decorative symbols are determined as stop symbols that are different from each other.

  Next, the integrated CPU 112 sets display commands according to the reach display variation display pattern determined on the main control board 101 side and the decorative design stop pattern determined in steps S713, S715, and S716 (step S71). S718: Effect form display control means, reach effect execution means), the process selection flag is updated to “1”, and the process is terminated (step S719). The display command set in step S718 is transmitted to the display control board 220 in the information output process (step S95), and based on the display command received by the display CPU 221 mounted on the display control board 220. The liquid crystal display 42 starts execution of variable display of decorative symbols.

  FIG. 26 is a flowchart illustrating an example of the decorative symbol variation process (step S701). In the decorative symbol variation process, the integrated CPU 112 first determines whether or not a variation stop command reception flag is set (step S755). The variation stop command reception flag is a flag that is set in step S604 of the command analysis process (step S91) described above and indicates that a variation stop command has been received from the main board 101. That is, if the variable stop command reception flag is not set in step S755 (NO in step S755), it is determined that the variable stop command has not been received, and the process is terminated. On the other hand, if the fluctuation stop command reception flag is set (YES in step S755), the fluctuation stop command reception flag is reset, and a display command for instructing stop of the decorative symbol is set (step S756). The display command set in step S756 is transmitted to the display control board 120 in the information output process (step S95), and based on the display command received by the display CPU 121 mounted on the display control board 120. On the liquid crystal display device 50, the decorative pattern change display stop is confirmed and displayed.

  Next, the integrated CPU 112 determines whether or not the big hit start command reception flag is set (step S757). The jackpot start command reception flag is a flag that is set in step S604 of the command analysis process (step S91) described above and indicates that a jackpot start command has been received from the main board 101. That is, if the jackpot start command reception flag is not set in step S757 (NO in step S757), it is determined that the jackpot start command is not received, the process selection flag is updated to “0”, and the process is terminated. (Step S759). On the other hand, if the jackpot start command reception flag is set (YES in step S757), the jackpot start command reception flag is reset, the process selection flag is updated to “2”, and the process ends (step S758).

  As described above, according to the configuration of the present embodiment, the variable pitching device includes a solenoid that has a plunger that can advance and retreat, and that moves the open / close piece between the first state and the second state, A drive transmission member that transmits the forward / backward movement of the plunger as a movement operation of the opening / closing piece, and an engagement position that engages the drive transmission member with the forward / backward movement of the plunger and an engagement that releases the engagement of the drive transmission member And a locking member that locks the open / close piece in a first state by restricting the movement of the drive transmission member at the engagement position. The member and the plunger are connected, and the movement of the lock member from the engagement position to the engagement release position is started substantially simultaneously with the start of the movement of the plunger that shifts the opening / closing piece from the first state to the second state. With a connecting part The drive transmission member connects the drive transmission member and the plunger, and the lock member is moved to the disengaged position after the movement of the plunger for moving the opening / closing piece from the first state to the second state is started. A connecting engagement portion is provided that transmits the movement of the plunger as a transition operation of the opening / closing piece after the movement. In this case, in the first state, the movement of the plunger constituting the solenoid is transmitted to the opening / closing piece via the drive transmission member, so that the opening / closing piece is in a closed state (including a state where a game ball can enter). On the other hand, in the second state, the movement of the plunger constituting the solenoid is transmitted to the opening / closing piece via the drive transmission member, and the opening / closing piece is opened. And in a 1st state, a lock member moves to the engagement position which engages with a drive transmission member with the movement of a plunger. Accordingly, the movement of the drive transmission member is restricted by the engagement with the lock member, and the opening / closing piece is locked in the first state. Further, when the state is shifted to the second state, the lock member moves to the disengagement position where the engagement with the drive transmission member is released along with the movement of the plunger. Is unlocked, and the open / close piece shifts to the second state. Therefore, in the first state, since the opening / closing piece is in the locked state, even if an external force that can move the plunger is applied to the opening / closing piece, the opening / closing piece cannot be moved in the opening direction. It is possible to prevent the variable pitching device from being opened by an unauthorized external force.

  Further, according to this configuration, when the opening / closing piece is shifted from the first state to the second state, the lock member is moved from the engagement position to the engagement release position substantially simultaneously with the start of movement of the plunger serving as the driving force. After the movement is started and then the lock member is moved to the disengagement position, the movement of the plunger is transmitted as the movement of the opening / closing piece by the drive transmission member. For this reason, the unlocking operation of the open / close piece by the lock member (the movement operation of the lock member to the disengagement position) and the movement operation of the open / close piece to the second state by the drive transmission member (plan through the drive transmission member). The start timing of the movement of the jar to the opening and closing piece) can be made different. In other words, by shifting the output timing of the plunger that is the driving force of the initial action at the time of unlocking and at the start of the transition to the second state, the burden on the solenoid can be reduced and distributed as a result. In the configuration that enables locking, a smoother opening / closing operation of the opening / closing piece can be invited.

  In the embodiment, a variable winning device 70 having a winning opening for paying out a prize ball as a game ball enters as an example of a variable entering device having a winning opening according to the present invention is shown as an example. However, it is not limited to this. That is, the variable pitching device does not necessarily have to pay out the winning ball when the gaming ball enters the pitching slot.

  The solenoid also has a coil spring that spirally winds around the outer periphery of the plunger and constantly urges the plunger in the advance direction. When no power is supplied, the excitation is released and the plunger advances by the urging force of the coil spring. While moving to move the open / close piece to the first state, it is energized when energized and the plunger moves backward against the biasing force of the coil spring to move the open / close piece to the second state. In this case, the solenoid can be energized to retreat the plunger when shifting to the second state where game balls can be easily entered compared to the first state. For this reason, since the power is consumed only when the control for shifting the variable pitching device to the second state is given to the player as a special game value, the variable pitching device (opening / closing piece) is opened and closed. The operation can be performed economically.

  The open / close pieces are formed of a pair of left and right open / close pieces that form a ball entrance by a gap between the open / close pieces. It is rotatably provided between the position and the tilting position that is the second state. In this case, the variable pitching device can be opened and closed by a rotation operation between the vertical position (first state) and the tilting position (second state) of the pair of left and right opening / closing pieces. In addition, with such a configuration, when the variable pitching device is opened, the opening amount of the pitching entrance can be efficiently earned with a small movement amount (rotation amount) of the opening / closing piece, so that the variable pitching can be efficiently performed. The ball device can be opened and closed.

  Further, the drive transmission member includes a pair of rotation shaft portions that rotatably attach the drive transmission member in addition to a coupling engagement portion that connects the solenoid and the drive transmission member by engagement with the plunger. A connecting engagement portion for connecting the solenoid and the drive transmission member by engagement with the plunger, and a rotation operation of the drive transmission member about the rotation shaft portion by engagement with the opening / closing piece to the opening / closing piece. The rotation of the drive transmission member is locked by engaging the transmission engaging portion that transmits and the lock member, and the rotation lock of the drive transmission member is released by releasing the engagement with the lock member. A locking engagement portion, and the opening / closing piece includes an engagement protrusion that converts the rotation operation of the drive transmission member into a movement operation of the opening / closing piece by engagement with the transmission engagement portion. In this case, the open / close piece can be shifted between the first state and the second state by transmitting the forward / backward movement of the plunger constituting the solenoid to the open / close piece via the rotation operation of the drive transmission member. Can be configured.

  In addition, the coupling engagement portion is formed in a shape that provides a slight gap between the distal end portion of the plunger in the coupled state of the drive transmission member and the solenoid, and has a slight play in the coupling engagement with the plunger. It is attached in a loose fit state. In this case, when an external force is applied due to fraud, etc., the external force is absorbed by a slight play between the coupling engagement portion and the tip of the plunger, so that it is directly applied to the opening / closing piece, the drive transmission member, or the solenoid. Since this is not the case, it is possible to avoid breakage of various components due to the locking of the opening / closing piece (the entrance).

  In addition, the engagement protrusion portion is formed of a synthetic resin material so that the inside can be visually recognized and is integrally formed with the piece main body of the opening / closing piece, thereby functioning as a maintenance portion corresponding to the force applied during the movement operation of the opening / closing piece. In this case, the engaging protrusion of the opening / closing piece that converts the rotation operation of the drive transmission member into the movement operation of the opening / closing piece is formed of a synthetic resin material so that the inside is visible and is integrally formed with the piece main body of the opening / closing piece. Functions as a maintenance department. Specifically, from the configuration in which the inside of the engaging protrusion is visible, it is possible to determine whether or not bubbles are included in the engaging protrusion at the manufacturing stage of the variable pitching device. Therefore, it becomes possible to sort out defective products whose engagement protrusions contain air bubbles and reduce the strength of the engagement protrusions and remove them at the manufacturing stage, thereby improving the manufacturing quality of the variable pitching device. it can. As a result, the opening and closing operation of the variable pitching device (the pitching port) can be smoothly performed continuously. Moreover, the structure which integrally forms the piece main body and engagement protrusion part of an opening / closing piece can raise the intensity | strength of the boundary part of a piece main body and an engagement protrusion part. For example, in order to improve the maintainability of the opening / closing piece (specifically, in order to avoid damage and breakage of the engaging protrusion), the engaging protrusion is constituted by another member made of a metal rod or the like. Is attached to the open / close piece piece body, the number of parts constituting the open / close piece is increased, and the attachment portion is liable to be loose in attachment such as insertion of another member (metal rod, etc.). Arise. On the other hand, in the above-described configuration, the engagement protrusion is formed integrally with the open / close piece piece main body, so that the open / close piece is not increased without increasing the number of parts and without causing partial backlash. Can improve the maintainability. Further, when the entire opening / closing piece is integrally formed of a synthetic resin material in this way, since there is no foreign matter mixed in, it becomes easy to melt the opening / closing piece and recycle it as a raw material.

  Further, the opening / closing piece is colored and painted on the portion other than the engaging protrusion and visible to the player in the assembled state of the variable pitching device. In this case, the decorativeness of the variable pitching device can be enhanced by coloring and painting the opening / closing piece formed of a synthetic resin material whose inside is visually recognizable. Even in this case, the engaging protrusion that receives the driving force of the solenoid via the drive transmission member is not colored and can be visually recognized inside. Can be confirmed by inspection. Also, if the engaging projections are painted with different colors to enhance the decorativeness of the variable pitching device, that is, if the main body of the opening and closing piece and the engaging projections are painted in two colors, Due to the nature of this, cracks and the like are likely to occur at the boundary of the coating, and the strength of the engaging protrusion (especially the boundary with the main body) deteriorates. The decorativeness of the variable pitching device can be enhanced without incurring deterioration.

  The variable pitching device includes an attachment base that integrally attaches the opening / closing piece, the solenoid, the drive transmission member, and the lock member and attaches the variable pitching device to the game area. In this case, by assembling various constituent members (opening / closing pieces, solenoids, drive transmission members, and lock members) to the mounting base, the variable pitching device can be configured as a unit. Attaching to and removing from the game area (game board) can be facilitated.

  In addition, there is provided a passing ball detecting means that is arranged in the game area and shifts the variable pitching device from the first state to the second state based on the detection of the passing of the game ball. In this case, when the game ball is driven into the game area, the variable pitching device is shifted from the first state to the second state based on the passage detection of the game ball by the passing ball detection means. Become. In other words, the variable pitching device can be shifted to the second state in accordance with the ball flow of the game ball that has been struck, so that it is possible to suppress a decrease in interest in the ball flow of the game ball in the game area. .

  A random number extracting means for extracting a random number based on the passing detection of the game ball by the passing ball detecting means; and a variable pitching device from the first state to the second state based on the random number value extracted by the random number extracting means. Transition determining means for determining whether or not to transition to the state, and the variable pitching device is transitioned to the second state in a predetermined period based on the determination of transition to the second state by the transition determining means Transition control means for controlling. In this case, if there is a passing detection of the game ball by the passing ball detection means, the variable pitching device is not necessarily shifted to the second state, but a lottery is performed based on the detection of the passing of the gaming ball by the passing ball detection means Since the variable pitching device can be configured to shift to the second state only when the lottery result is a win, the rare value of the gaming privilege for shifting the variable pitching device to the second state can be increased. .

  Also, a start winning opening that is arranged in the game area and is capable of winning a game ball, a winning detection means that detects that a gaming ball has won the start winning opening, and at least a detection of the gaming ball by the winning detection means In response, a ball payout means for paying out a predetermined number of game balls, a win determination means for determining whether or not to give a profit to the player based on detection of the game balls by the winning detection means, and a corresponding drop determination means Profit granting state control means for controlling to a profit granting state that grants a profit to the player based on a determination that the player should be given a profit, and the start winning opening is composed of a variable pitching device Is done. In this case, the winning determination is performed based on the winning at the start winning opening constituted by the variable pitching device, and the state is controlled to a profit granting state in which a profit is given to the player when the determination result is a win. For this reason, in the determination of whether or not to enter the profit granting state, winning at the starting prize opening is the most important opportunity, so the second state of the variable pitching device that greatly affects the winning at the starting prize opening The player's interest in the transition to can be greatly increased.

  Also, a display unit arranged in the game area for displaying the symbol information in a variable manner, and a symbol according to the determination result after a predetermined period of time is displayed on the display unit based on the determination result of the winning determination unit. Display control means for stopping and displaying the display result of the information, and for stopping and displaying the specific display result as the display result of the symbol information when the winning determination means determines that the profit should be given to the player. In this case, since the winning determination based on the winning at the start winning opening can be produced by the display change of the symbol information by the display means, it is possible to suppress a decrease in visual interest.

  In addition, there is provided a big prize opening device having a big prize opening where a large number of game balls can be won by shifting from the closed state to the opened state when controlled by the profit grant state control means. In this case, it is possible to give the player as a profit granting state that a large amount of prize balls are paid out to the player in accordance with winning in the big winning opening.
