Abstract

PROBLEM TO BE SOLVED: To provide a Pachinko machine that can change the continuous probability rate of a round play without making the motion of a sorting means provided in a variable prize winning device controlled intricately.SOLUTION: The Pachinko machine is provided with a game control means (130) that provides a jackpot based on a game ball which enters a variable prize winning device (1) passing through a specific area (V1) out of multiple areas. The game control means not only controls the motions of the sorting means (50, 75) during a round game to create two statuses: a high-probability rate advantageous sorting status that the game ball passes the specific area and a lower (compared with this advantageous status) probability rate disadvantageous sorting status that the game ball passes the specific area: but also controls so that the opening/closing motion pattern of the variable prize winning device at least in the advantageous sorting status differs depending on the kind of the jackpot won by an electronic lottery means (110).

Description

  The present invention relates to a pachinko machine equipped with a variable winning device having distribution means capable of distributing the course of a game ball in various directions.

  Conventionally, in a pachinko machine, a so-called pachinko ball (hereinafter referred to as a game ball) is fired into a game area formed on a game board surface continuously or intermittently by a launch mechanism, and the game ball is arranged in the game area. A game state advantageous to the player (big hit game) is started by entering the variable winning device and further taking a game ball into a specific area (so-called V zone) formed in the variable winning device. A form of pachinko machine is known.

  As shown in Patent Document 1, the basic configuration of the variable prize winning device includes a case that opens forward in the game area and forms a space for receiving a launch ball, and a prize in a start opening provided in the game area. An opening / closing blade piece (opening / closing body) that opens an entrance provided in the housing as an opportunity, and a plurality of regions provided in the interior of the housing, by a sorting member (sorting means) provided in the housing, By changing the course of the game ball that has entered the housing, the game ball that has entered the direction of a specific winning area (specific area) or other area that triggers a big hit in a plurality of areas. It is the structure which distributes.

  Further, in Patent Document 1, when a big hit game is provided, one big hit process (one round game) is performed until the opening / closing wing piece opens and closes 18 times or 10 game balls are won in the variable winning device. ) Is executed, and when a game ball passes through the specific winning area and becomes a V winning in the one big hit processing, the maximum of eight times (round) big hit processing is continued. .

  Furthermore, in this patent document 1, in one big hit process, it is controlled so that the direction of the distribution member is different, for example, until the opening / closing blade piece is opened and closed 7 times and after reaching 7 times. Specifically, until the opening and closing blade piece is opened and closed seven times, the sorting member is not directed toward the center when the opening and closing blade piece is in the open state (is in an unfavorable distribution state). . Therefore, the probability that the game ball wins V is low in the section until the open / close wing piece is opened and closed seven times. On the other hand, when the number of times of opening / closing of the opening / closing blade piece reaches 7, the distribution member is directed toward the center when the opening / closing blade piece is in the open state (is in an advantageous distribution state). Therefore, in the section after the number of times of opening and closing the opening and closing wing pieces has reached 7, the probability that the game ball will win V increases.

  As described above, in the pachinko machine described in Patent Document 1, when a game ball wins in the variable winning device and passes a specific winning area, a big hit game in which a round game is continued up to the upper limit number of times with V winning as a continuing condition is provided. Is done. And since the posture of the distribution member is changed from a low probability of winning a V prize to a high state during one round game, the continuation probability of the round game is determined by the variable ball winning device. It depends on the timing of winning the prize and the state (posture) of the sorting member. In other words, Patent Document 1 does not intentionally change the continuation probability of a round game depending on the type of jackpot game.

  On the other hand, Patent Document 2 discloses a variable prize including a pair of left and right opening / closing pieces, a storage member that temporarily stores a game ball, and a swing member (distribution means) that swings a specific area. An apparatus configuration is disclosed. In this patent document 2, when releasing the game ball stored by the storage member, the probability that the game ball enters the specific region can be changed depending on whether or not the specific region is rocked. ing. Specifically, when a stored game ball is released, a high probability round (advantageous vibration) in a state in which the specific ball is controlled to stop at a position where the game ball is likely to enter the specific region. Minute state) and a low-probability round (unfavorable state) in which the game ball is controlled to move between a position where the possibility that the game ball enters the specific area is high and a low position. For example, out of a maximum of 15 round games, the seventh round is a high probability round, and the eighth and subsequent rounds are low probability rounds.

  In this way, the continuation probability of the round game greatly depends on whether the round game is the high probability round or the low probability round, rather than the timing at which the game ball is taken into the variable winning device. Therefore, according to Patent Document 2, even if it is one big hit game, for example, the round game is easy to continue until the seventh time, but the round game is intentionally round so that it is difficult to continue the round game after the eighth time. The continuation probability of the game can be changed. That is, according to Patent Document 2, when one big hit game is provided, for example, the round game is almost certainly continued until the seventh round, but after that, it is possible to create a game characteristic that depends on luck. become.

Japanese Patent No. 2545043 (paragraphs 0049 to 0056, 0073, etc.) JP 2004-073756 A (paragraph 0025, etc.)

  However, in Patent Document 2, round games are performed by controlling the operations of the storage member and the swing member (distribution means) that are movable in the variable winning device so as to be different for the high probability round and the low probability round. Therefore, there is a problem that the control of these members becomes complicated.

  Therefore, in view of the above circumstances, the present invention can change the continuation probability of a round game without complicated control of the operation of a distribution means that is provided inside the variable winning device and distributes game balls. The purpose is to provide a pachinko machine.

  In order to achieve the above object, the present invention provides a game board having a game area in which game balls flow down, a start opening provided in the game area, and start detection for detecting that a game ball has won a prize in the start opening. An electronic lottery means for performing a lottery based on the fact that the start detector has detected a game ball, a variable prize winning device that opens and closes when a lottery is made by the electronic lottery means, and a variable prize winning device. A game control means for providing a jackpot game based on the fact that a winning game ball has passed a specific area among a plurality of areas, and the jackpot game is a round in which the variable winning device is opened and closed until a predetermined condition is satisfied. The game control means is configured to provide a game up to a predetermined upper limit number of times, and the game control means sets the next round game on condition that a game ball has passed through the specific area during the round game. In the pachinko machine that controls to end the jackpot game on the condition that the game ball does not pass through the specific area during the round game, the variable winning device has the game ball that has won the prize , Distribution means for allocating to the specific area and other areas, the game control means controls the operation of the distribution means during one round game, the game ball is the specific area The electronic lottery is controlled so as to generate two states, that is, an advantageous distribution state with a high probability of passing through and an unfavorable distribution state in which a game ball has a low probability of passing through the specific region compared to the advantageous state. Control is performed so that the pattern of the opening / closing operation of the variable prize-winning device in at least the advantageous allocation state differs according to the winning type won by the means.

  According to the present invention, since the pattern of the opening / closing operation of the variable winning device during the round game is controlled differently according to the winning type won by the electronic lottery means, the game ball is placed in the variable winning device during the round game. It is possible to change the timing and number of images taken in. The change in the timing and number of game balls taken into the variable winning device also changes the probability that the game balls pass a specific area in one round game. Therefore, the probability that the round game will continue to change. That is, the present invention can change the continuation probability of a round game by changing the pattern of the opening / closing operation of the variable winning device during the round game. In other words, according to the present invention, it is not necessary to control the operation of the sorting member in a complicated manner as in the above prior art in order to change the continuation probability of the round game.

  In the present invention, “the pattern of the opening / closing operation of the variable winning device is different” includes a case where at least one of the opening / closing frequency and the opening time of the variable winning device is different.

  The summary of the invention does not enumerate all the necessary features of the present invention, and sub-combinations of these feature groups can also be the invention.

In addition, a round display unit 31C including a segment display is formed below the specific area display unit 31B, and the number of rounds in a big hit game described later is displayed.

  The left and right wall portions 32; 32 extend upward from both end portions of the lower wall portion 31, and the front surface portion is formed in a shape imitating a human shape, and between the front surface portion and the front surface portion of the base plate 25. The approaching ball detector holding part 32A; 32B is bent.

  The approach sphere detector holding part 32A; 32B is a member for holding the approach sphere detector 400A; 400B (see FIG. 3) inserted inside, and is detected by the approach sphere detector 400A; 400B held inside. It has a game ball entrance 34 set to be approximately the same diameter as the hole diameter. The game ball entrance 34 is a through hole having a diameter larger than the diameter of one game ball and smaller than the diameter of two game balls, and the game ball P is one of the upper and lower game ball entrances. By passing through 34, it becomes possible to enter the internal space R of the housing 30 via the opening 25B.

  The game ball P passing through the game ball entrance 34 is detected by the approach ball detector 400A or 400B held inside. The approach ball detector 400A or 400B outputs a detection signal to the main controller 100 described later based on the fact that the game ball P has passed through a detection hole having the same diameter as the game ball entrance 34. Also, the approach ball detectors 400A and 400B are held by the approach ball detector holding portions 32A and 32B formed by bending in a U shape so that their inclination angles are different, as indicated by broken lines. The path of the game ball P after passing through the entering ball detector 400A; 400B differs depending on which detector the entering ball detector 400A; 400B passes through.

  When the window portion 15 is closed, the distance between the lower wall portion 31 and the left and right wall portions 32; 32 and the window portion 15 is narrower than the diameter of the game ball P, and the lower wall portion 31 and the left and right wall portions 32; The game ball P cannot enter the internal space R of the housing 30 from the front side of 32. In other words, the game ball P cannot enter the internal space R unless it passes through the game ball entrance 34 located between the base plate 25 and the front surfaces of the left and right wall portions 32; 32.

  A pair of opening / closing bodies 40; 40 are rotatably provided outside the game ball entrance 34 in the left-right direction and between the base plate 25 and the front surfaces of the left and right wall portions 32; 32. As shown in FIG. 4, the opening / closing body 40; 40 is a member that can be opened and closed by driving a pair of solenoids Sol 1; Sol 1 mounted behind the housing 30. The opening / closing body 40; 40 includes a flat guide bar 40A that guides the game ball P flowing down from the outer side in the left-right direction to the inner side, and a design plate part 40B formed on the front surface of the guide bar 40A. In the open state, the game ball P is guided toward the game ball entrance 34 by rolling on the guide bar 40A.

Note that a tip 77A of an upper change portion 77 of a course changing portion 75, which will be described later, protrudes on the side drop port 71; 71, and prevents the game ball rolling toward the side drop port 71; 71 from falling. Or tolerate.

  In the central drop port 70, a sorting rotator 50 is provided. The sorting rotator 50 is a dome-like structure having a guide wall 51 that rotates in a certain direction inside a circular central drop port 70 and a connection flange 52 provided above the top of the guide wall 51. Then, the path of the game ball P that rolls backward on the first stage 63 is distributed to the central drop port 70 or the side drop port 71. The guide wall 51 is a cylindrical body having a lower opening slightly smaller in diameter than the edge forming the central drop opening 70, and is a substantially semicircular intake opening (distribution) opened upward from the lower edge. A plurality of holes) 53. The intake port 53 is a hole opened at intervals of 120 °, for example, along the circumferential direction of the guide wall portion 51.

  Of the game balls P that roll backward on the first stage 63, only the game balls P that have passed through the take-in port 53 in a timely manner fall down from the central drop port 70 as indicated by the arrow P1 in FIG. The game ball P that has collided with the guide wall 51 at the timing and is guided to the one of the side drop openings 71 falls downward from the side drop opening 71 as indicated by an arrow P2. That is, the sorting rotator 50 is a game part that changes the course of the game ball P rolling on the first stage 63, and the entry timing, the rolling speed, the rolling trajectory of the game ball P, and It has a function of randomly distributing the course of the game ball P rolling on the first stage 63 according to various conditions such as the circumferential angle of the intake port 53 of the sorting rotator 50. The game balls distributed by the distribution rotating body 50 and guided to the second stage 64 are finally distributed to the specific area V1 and the general area V2.

  As shown in FIG. 6, the sorting rotator 50 is connected to a rotation mechanism 55 including a motor M via a connection flange 52. The connection flange 52 is a disc body provided on an output shaft extending from the top of the dome-shaped guide wall 51, and has a substantially rectangular engagement portion 52A at the center. Further, in the circumferential direction of the connection flange 52, mounting holes 52B extending radially inward are opened at equal intervals (see FIG. 5).

  As shown in FIG. 6, a circular plate 65 having a third gear 58 (described later) is placed on the connection flange 52 via an engagement portion 52 </ b> A, a plurality of attachment holes 52 </ b> B, and fixing means. The circular plate 65 has a third gear 58 provided around the rotation axis at the center, and a notch 66 for detecting a position extending inward in the radial direction in a part of the circumferential direction. The cut hole 66 is a fine hole serving as a reference for sensing by the positioning sensor 500 described later. When the cut sensor 66 is detected by the positioning sensor 500, the sorting rotating body 50 stops at a predetermined position. The positioning sensor 500 is, for example, a photocoupler having a light projecting unit and a light receiving unit, and operates OFF while the light emitted from the light projecting unit is blocked by a portion other than the cut hole 66. Thus, when the light emitted from the light projecting unit reaches the light receiving unit, the ON operation is performed. The stop control of the motor M based on the positioning sensor 500 will be described later.

  As shown in the figure, the rotation mechanism 55 includes a motor M composed of a pulse motor mounted on the rear side of the housing 30 via an attachment mechanism, a first gear 56 connected to the output shaft of the motor M, and the first gear. 56, a second gear 57 that meshes with the second gear 56, and a third gear 58 that meshes with the second gear and is connected to the engaging portion 52A of the connection flange 52 and is connected to the circular plate 65. The speed is reduced and transmitted to the sorting rotator 50.

  7 is a cross-sectional view taken along the line BB in FIG. FIG. 8 is a front view and a side view of the course changing section 75. The course of the game ball P that has dropped from the side drop port 71; 71 will be described with reference to FIG. As shown in FIGS. 7 and 8, the game ball P that has fallen from the side drop port 71 is moved forward by a lower change portion 78; 78 of a course change portion 75 provided in the drop passage 73. It is guided to the two stages 64 or the discharge passage 91 located at the rear.

  As shown in FIG. 8, the course changing section (distributing means) 75 includes a base body 76 connected to the solenoid Sol <b> 2 via a link mechanism, an upper side changing section 77; 77 protruding on the side drop port 71, and The lower change part 78; 78 located in the fall passage 73 is tilted in the front-rear direction by driving the solenoid Sol2 mounted on the rear side of the housing 30.

  The base body 76 is a plate-like member extending between the side drop ports 71:71, and a rotating shaft 82 extending in the left-right direction is inserted between the attachment pieces 76A formed below. The attachment piece 76A has a link piece 76B extending rearward at the center, and the link piece 76B is connected to the solenoid Sol2 via a connecting hole 76C. By driving the solenoid Sol2, the base body 76 rotates in the direction indicated by the arrow in FIG. 8C with the rotation shaft 82 as the center of rotation, and the upper change portion 77 formed integrally with the base body 76 projects forward. .

  The upper changing portions 77; 77 are a pair of projecting pieces formed at the left and right end portions of the base body 76. The hooks incline forward from the upper end portion of the base body 76 and gently curve toward the end portions. Shape. As shown in FIG. 8 (b), the tip 77A of the upper changing portion 77; 77 is separated from the upper surface of the first stage 63 positioned below and the diameter of the game ball P when the solenoid Sol2 is not energized. The game ball P rolling on the first stage 63 toward the side drop port 71; 71 is allowed to drop. On the other hand, as shown in FIG. 8C, the tip 77A of the upper changing portion 77; 77 tilts forward with the rotation of the base body 76 when the solenoid Sol2 is energized and is positioned below. The upper surface of the stage 63 is close to the diameter of the game ball P and approaches the side drop port 71; 71 on the first stage 63 to prevent the game ball P from falling or to bounce forward. . In other words, the upper changing portion 77; 77 is a member that changes the course of the game ball P rolling on the first stage 63.

  The lower side changing portions 78; 78 are a pair of projecting pieces provided outside the pair of projecting plates 79 projecting forward from the front surface of the base body 76, and the central axis 80 is moved along with the rotation of the base body 76. Tilt as the center. One end of the central shaft 80 is inserted into the lower change portion 78; 78, and the other end portion is inserted into a bearing portion formed in the housing 30 (not shown). Further, a tilting shaft 81 is rotatably attached in front of the central shaft 80. The tilting shaft 81 is a shaft body interposed between the notch 79A and the lower changing portion 78 provided in front of the projecting plate 79, and the projecting plate 79 is moved downward as the base body 76 rotates. By tilting, the tilting shaft 81 tilts downward, and the lower change portion 78 tilts around the center axis 80 as a rotation center. That is, the lower side change portion 78; 78 is a member that tilts in synchronization with the tilting operation of the upper side change portion 77; 77.

  And as shown in FIG.8 (b), when the solenoid Sol2 is de-energized, the lower side change part 78; 78 stopped in the state inclined backward, and fell from the upper side drop port 71; 71. The game ball P is guided backward. The game ball P guided rearward of the lower side change portion 78; 78 is detected by the discharge ball detector 700 via the discharge passage 91 and then discharged to the outside of the housing 30.

  On the other hand, when the solenoid Sol2 is energized, the lower change portion 78; 78 stops in a state of being inclined forward, and the game ball P dropped from the upper side drop port 71; 71 is moved to the front second stage 64 side. To guide. The game ball P guided forward from the lower side change portion 78; 78 rolls forward on the second stage 64 and is taken into the specific area V1 or the general area V2 described later, and then the discharge passage 91. After being detected by the discharge ball detector 700, it is discharged outside the housing 30.

  As described above, the lower change portion 78; 78 is a member that tilts in synchronization with the upper change portion 77; 77, and the second stage 64 that positions the game ball P falling in the drop passage 73 forward. It is a member which distributes the course to the discharge passage 91 side located on the side or rear. Therefore, even when the path of the game ball P rolling on the first stage 63 is guided to the side drop opening 71; 71 side, as shown in FIG. 8 (c), the side drop opening 71; If the fall timing from 71 coincides with the timing when the lower side change part 78; 78 is tilted forward, it will be guided to the second stage 64 and will enter the specific area V1 established in front of the second stage 64. It becomes possible to obtain an opportunity to be captured.

  On the other hand, if the drop timing from the side drop port 71; 71 coincides with the timing at which the lower side changing portion 78; 78 is inclined rearward, it is guided to the discharge passage 91 without being guided to the second stage 64. Therefore, it is not possible to obtain an opportunity to be taken into the specific area V1 established in front of the second stage 64. The solenoid Sol2 is driven and controlled, for example, at random by the main controller 100 during a normal game, and the course of the game ball P is distributed according to the timing. In this way, the game balls whose course has been changed by the course changing section 75 are distributed to the specific area V1, the general area V2, or the discharge passage 91. Therefore, the course changing section 75 is provided with the above-described sorting rotator 50. Together with this, the distribution means of the present invention is constituted.

  The second stage 64 is a plate-like member that is spaced below the diameter of the game ball P by more than the upper first stage 63 and extends in the front-rear direction. The second stage 64 is formed as a slope inclined forward, and falls from the game ball P or the side drop port 71; The game ball P guided by 78 is rolled forward.

  As shown in FIGS. 3 and 5, the front edge portion 64 </ b> A of the second stage 64 is shorter than the front edge portion 63 </ b> A of the first stage 63, and the specific region is between the front edge portion 64 </ b> A and the lower side wall portion 31. A plurality of areas including V1 are opened. The specific region V1 is an intake port that is opened at the central portion in the left-right direction of the housing 30, and the partition wall 90; 90 and the partition wall 90; 90 facing each other between the front edge portion 64 A and the lower wall portion 31. And a special prize detector 600 interposed therebetween. The special prize detector 600, when the game ball P rolls forward from the rear of the second stage 64 and is taken into the specific area V1, a detection signal indicating that the game ball P has been taken into the specific area V1 will be described later. Output to the control device 100.

  The main control device 100 executes a big hit game start process, which is a game state advantageous to the player, by the input from the special prize detector 600. That is, the big hit game condition is that the game ball P is taken into the specific area V1. In addition, the game ball taken into the specific area V1 is discharged to the outside of the housing 30 after being detected by the discharge ball detector 700 through the discharge passage 91 formed below.

  The game ball P (outer ball) that rolls forward on the second stage 64 and has not been taken into the specific area V1 is taken into the general area V2; V2. The general area V2; V2 is an intake port that is opened in the left-right direction across the specific area V1, and is provided between the partition walls 90; 90 and the left and right wall portions 32; 32. In addition, the game ball taken into the general area V <b> 2 is detected by the discharge ball detector 700 through the discharge passage 91 and then discharged to the outside of the housing 30. That is, even if the game ball P is taken into either the specific area V1 or the general entry area V2, it is detected by the discharge ball detector 700 via the discharge passage 91 and then discharged outside the housing 30. .

  The shape of the second stage 64 is such that the game ball guided from the central drop port 70 to the second stage 64 is more specific region V1 than the game ball guided from the side drop port 71 to the second stage 64. It is set so that the probability of being taken in is high. Therefore, it can be said that it is easier for the player to get a big hit game opportunity by passing the central drop opening 70 opened in the first stage 63, and the game ball P rolling on the first stage 63 is distributed to the sorting rotator. The attention is easily directed to being taken into the 50 intake ports 53.

  FIG. 9 is a schematic block diagram centering on the main control device 100 of the pachinko machine 10 including the variable winning device 1. Hereinafter, an outline of control of the pachinko machine 10 will be described. In the figure, the pachinko machine 10 includes a main controller 100 that controls the entire game. The main controller 100 is a so-called microcomputer having a CPU, a ROM in which a program necessary for a game such as prize ball information and effect information is written, and a RAM as a work area necessary for executing the program. Thus, each gaming component connected to the output side is controlled based on the input signal of each detector connected to the input side. The main controller 100 includes a first start detector 200A, a second start detector 200B, a general winning detector 300, an approach ball detector 400A; 400B, a positioning sensor 500, a special sensor via a detection circuit and an input port (not shown). A winning detector 600 and a discharge ball detector 700 are connected.

  As shown in FIG. 9, the main control device 100 includes a special symbol success / failure lottery unit (electronic lottery means) 110 that performs electronic lottery related to special symbols when a game ball wins a winning winning opening 2A, 2B, A special symbol type determination that determines the contents of the jackpot game, that is, the opening and closing operation pattern of the variable winning device 1 in the jackpot game, triggered by the winning of the game ball at the start winning ports 2A and 2B Unit 120 and a jackpot game control unit (game control means) 130 for controlling the opening / closing operation of the opening / closing body 40; 40 of the variable winning device 1 and providing a jackpot game, and performs various processes relating to the game. Yes.

  First, an outline of a game processing procedure performed by the main controller 100 will be described with reference to FIG. As shown in FIG. 12, the main controller 100 determines whether or not the game ball has won the start winning opening 2A, 2B (step S1). When winning (Yes in step S1), main controller 100 acquires a special symbol random number and a symbol determining random number (step S2). Next, in step S3, the main controller 100 determines the number of opening / closing operations (one or two times) of the opening / closing body 40; 40. Next, in step S4, main controller 100 determines an opening / closing pattern (any one of symbols A to F) of opening / closing body 40; 40 in the big hit game.

  Next, in step S5, main controller 100 starts changing the special symbol. The special symbol variation is displayed on the special symbol display device. Next, in step S6, main controller 100 stops the variation of the special symbol. Note that the variation time of the special symbol is preset to 0.2 seconds. Next, in step S7, main controller 100 opens / closes opening / closing body 40; 40 by the number of times (one or two times) determined in step S3. Next, in step S8, main controller 100 determines whether or not the game ball has passed through specific area V1 (whether or not V winning). If yes in step S8, control proceeds to step S9 and determined in step S4. Provide the contents of the jackpot game. On the other hand, in the case of No in step S8, one game process is ended. Note that the process is also ended in the case of No in step S1.

  Subsequently, each control of the game performed in the above procedure will be described in detail below.

<About opening / closing body opening control>
The opening control of the opening / closing body 40; 40 is performed based on a lottery result of the special symbol winning / failing lottery section 110. The special symbol success / failure lottery unit 110 updates the value of the loop counter one by one in a predetermined range (0 to 399 in this embodiment) based on an interrupt signal periodically input (for example, every 2 milliseconds). The special symbol random number generator 111 for generating software random numbers and the fact that a game ball has won the start winning opening 2A, 2B (a detection signal from the start detectors 200A, 200B is sent to the main controller 100) The special symbol random number acquiring unit 112 that acquires (latches) one special symbol random number generated by the special symbol random number generating unit 111 and the special symbol random number acquiring unit 112 acquired at the input timing) An open / close count determining unit 113 that determines the number of times to open and close the open / close body 40; 40 of the variable winning device 1 based on the design random number, and the open / close count determining unit 113 determines the open / close count. And a closing count table 114 referred to when.

  As shown in FIG. 10, the open / close count table 114 associates the value of the special symbol random number with the open / close count of the open / close body 40; 40. Specifically, if the value of the special symbol random number is 0 to 299, the opening / closing body 40; the number of opening / closing of the opening / closing body 40 is associated with one small hit A, and the value of the special symbol random number is 300 to 399. If there is, the small hit B with the opening / closing body 40; Therefore, the probability that the number of times of opening and closing is 2 is lower than the probability of being 1 time. In the case of the small hit A, the main controller 100 performs the drive control once so as to demagnetize the solenoid Sol1; Perform the operation of closing for 45 seconds and then closing once. In the case of small hit B, the main control device 100 sets the solenoids Sol1; Sol1 in the excited state for 0.75 seconds and then performs drive control twice so as to demagnetize the opening / closing bodies 40; Perform the closing operation twice after the opening state for 75 seconds.

  Here, in the present embodiment, when a game ball wins the start winning opening 2A, 2B, the winning is invalid (for example, when the opening / closing body 40; 40 is in an opening / closing operation or a big hit game) The special symbol random number acquisition unit 112 acquires any one random number value from random number values 0 to 399. As shown in FIG. 10, the opening / closing body 40; It is decided to open and close twice or twice. Therefore, when a lottery is performed by the special symbol success / failure lottery section 110, the small winning (winning) of either the small hit A or B must be won, and the opening / closing body 40; 40 must be opened or closed once or twice. become. That is, when a game ball wins the start winning opening 2A, 2B, the opening / closing body 40; 40 is opened and closed unless the winning timing is invalid.

  Note that the timing at which the opening / closing body 40; 40 moves to the open state is when the special symbol stop display is confirmed. More specifically, when a game ball wins in the start winning opening 2A, 2B, a lottery process is performed by the special symbol winning lottery unit 110, and based on the result, the special symbol variation display on the special symbol display device described above is performed. Is displayed and a predetermined stop mode is displayed on the display device 0.2 seconds later (in this embodiment, the variation time is fixed to 0.2 seconds), thereby confirming the display of the lottery result. . Solenoid Sol1; Sol1 is excited at this fixed timing, and the opening / closing body 40; 40 opens and closes.

  The main controller 100 transmits a command to the effect controller 100A and the payout controller 100B when there is an input signal from the first start detector 200A or the second start detector 200B.

<Prize ball payout control>
The main controller 100 generates a payout command based on input signals from the first start detector 200A, the second start detector 200B, the general winning detector 300, and the approach ball detector 400A; 400B, and the payout controller 100B. Is sent to. The payout command includes payout number information for a single game ball winning, and the payout control device 100B controls the prize ball payout device 150 based on the information to pay out a prize ball to the player. The payout control device 100B is connected with a payout switch SW1, and stops paying out prize balls when the prize ball count output from the payout switch SW1 matches the payout number information.

<Direction control>
The main control device 100 performs different production commands based on input signals from the first start detector 200A, the second start detector 200B, the general winning detector 300, the approach ball detector 400A; 400B, and the special winning detector 600. Is generated and sent to the effect control device 100A. The effect control device 100A drives the effect board 28, the indicator lamp L, and the speaker S based on the effect command from the main control device 100 to suggest the game state to the player or perform an effect that excites the game.

<Launch control>
The firing control device 100 </ b> C is a device that controls the operation of the launch mechanism 21 in accordance with the amount of rotation of the handle 20. More specifically, a control process is performed such as energizing the launch mechanism 21, stopping energization, or changing the energization current.

<About motor rotation control during normal games>
Next, rotation control of the motor M during the normal game will be described. The normal game is a game other than the big hit game described later. When the main controller 100 receives an input signal from the first start detector 200A or the second start detector 200B, the main control device 100 executes a lottery by the special symbol winning lottery unit 110, and when the display of the lottery result is fixed, Energize to start rotation. The rotation speed of the motor M at this time is 1250 pps, for example, and the motor M shifts to the high speed section through the acceleration section.

  Then, when the opening / closing body 40; 40 is opened by the input from the first start detector 200A or the second start detector 200B, but there is no input by the entering ball detector 400A or 400B within a predetermined time, that is, When the game ball does not enter the internal space R of the housing 30, the main controller 100 stops the driving of the motor M based on the input from the positioning sensor 500. Thus, the sorting rotator 50 that has started rotating stops at the same position (that is, the origin position) every time. That is, as shown in FIG. 6A, since the cut hole 66 of the circular plate 65 is provided at one place on the circumference, the intake port 53 of the sorting rotator 50 facing the cut hole 66 every time. Stop with the player facing the front. Thus, in this embodiment, the position where the intake port 53 of the sorting rotator 50 faces the front is the origin position, and the rotation control of the motor M is performed so as to stop every time at this position. .

  On the other hand, when there is an input from the approaching ball detector 400A or 400B, the main controller 100 decelerates the rotational speed of the motor M based on the input. At this time, the rotational speed of the motor M is, for example, 845 ppm, and shifts to the low speed section through the deceleration section. Further, main controller 100 continues the low-speed rotation of motor M until there is an input from discharge ball detector 700, that is, until game ball P is discharged from inside housing 30. Then, when there is an input from the discharge ball detector 700, the main controller 100 stops driving the motor M based on the input from the positioning sensor 500. As a result, the sorting rotator 50 stops at the same position (that is, the origin position) each time as described above.

  Thus, the sorting rotator 50 of the variable winning device 1 rotates at a high speed when the result of the lottery based on the detection of the game ball by the first start detector 200A or the second start detector 200B is confirmed. Since the rotation speed is changed to a low speed based on the detection of the game ball by the approach ball detector 400A or 400B, the angle of the sorting rotating body 50 at the time when the game ball enters the internal space R of the housing 30 However, depending on the time (time lag) from when the game ball is detected by the first start detector 200A or the second start detector 200B until it is detected by the approach ball detector 400A or 400B, the internal space R The angle (rotational position) of the sorting rotator 50 at the time of entering can be made different every time.

  Therefore, the game ball that has entered the internal space R is not guided to be biased to either the central drop port 70 or the side drop port 71, and the path of the game ball in the internal space R is varied. be able to.

  Furthermore, since main controller 100 waits for an input from positioning sensor 500 and then stops motor M, sorting rotator 50 is always at the origin position where intake port 53 faces the front. When the game ball P is stopped and the next game ball P wins the start winning opening 2A, 2B, it always starts to rotate from the origin position.

  Therefore, in the present embodiment, when the first start detector 200A or the second start detector 200B detects the game ball P and the game ball P passes the game ball entrance 34 at the same timing, the distributed rotation is performed. The rotational position of the body 50 is always the same. That is, the intake port 53 always rotates to the same position. Thus, regardless of whether a skilled player or an inexperienced player plays a game, the game ball P enters the game ball entrance 34 after the game ball P has won the start winning opening 2A, 2B. If the time until passing through is the same, the angle of the sorting rotator 50 is the same, so that the game balls P thereafter are almost the same.

<About control of jackpot game>
When a detection signal is input to the main control device 100 by a special winning detector 600 provided in the specific area V1 established in the internal space R (so-called V winning), after a predetermined time elapses, The big hit game process which is an advantageous game state is executed. Specifically, the jackpot game control unit 130 of the main control device 100 performs the opening / closing operation of the opening / closing body 40; 40 by continuously driving the solenoid Sol1; Sol1 based on the input from the special prize detector 600. It carries out continuously according to a predetermined opening / closing pattern.

  The opening / closing operation of the opening / closing body 40; 40 during the big hit game is, for example, until the total number of detections of the game ball by the entry ball detector 400A or 400B reaches 10 counts, or the total number of opening / closing of the opening / closing body 40; A game ball enters a specific area V1 during one round game, which is defined as one round game until the earlier condition (hereinafter referred to as a round ending condition) is satisfied. (V winning) is repeated 12 rounds (predetermined upper limit). In other words, the jackpot game of the present embodiment has a content in which a round game of 12 rounds at the maximum continues under the condition that the V winning in the round game is continued. Therefore, the possibility that the game ball is detected by the approach ball detector 400A or 400B is dramatically improved as compared with the case of the normal game, and a large amount of prize balls can be obtained within a short time. Note that the number of rounds is not limited to this, and may be set at random, for example, once, three times, five times, ten times, or fifteen times.

  Here, in the present embodiment, there are six types of contents of the jackpot game, and the special symbol type determination unit 120 determines which content to use. As shown in FIG. 9, the special symbol type determination unit 120 sets the value of the loop counter to a predetermined range (0 to 5 in this embodiment) based on an interrupt signal periodically (for example, every 2 milliseconds). ) In the event that the game ball has won a prize at the start winning holes 2A and 2B (detection from the start detectors 200A and 200B). The symbol determination random number acquisition for acquiring (latching) one symbol determination random number (hereinafter referred to as “symbol random number”) generated by the symbol determination random number generator 121 (at the timing when the signal is input to the main controller 100). The content of the big hit game, that is, the pattern of the opening / closing operation of the opening / closing body 40; 40 of the variable winning device 1 is determined based on the symbol 122 acquired by the unit 122 and the symbol determining random number acquiring unit 122. That the opening and closing pattern determination unit 123, the opening and closing pattern determination unit 123 and an opening and closing pattern table 124 to be referred to when determining the opening and closing patterns.

  In the open / close pattern table 124, as shown in FIG. 11, the design random numbers and the open / close patterns of the open / close bodies 40; 40 are associated in advance. The opening / closing pattern of the opening / closing body 40; 40 is configured by a combination of “normal opening”, “short opening”, and “long opening” which will be described later. Specifically, the jackpot game consisting of 12 rounds is divided into a first game section from 1 round (R) to 4 rounds (R) and a second game from 5 rounds (R) to 8 rounds (R). Divided into sections and the third game section from 9 rounds (R) to 12 rounds (R), and the first half game in which the opening / closing body 40; The opening and closing patterns in the first half game and the second half game in the respective game sections from the first game section to the third game section are divided into the 11th to 18th second half games. An open / close pattern is configured by setting any one of “long open”.

  “Normally open” is an open / close pattern in which the opening time of the opening / closing body 40; 40 is 0.75 seconds, and “short opening” is 0 time of opening of the opening / closing body 40; 40 once. The open / close pattern is 45 seconds, and “long open” is an open / close pattern in which the open time of the open / close bodies 40; 40 is 1.2 seconds. The longer the opening / closing body 40; 40 is opened, the more likely it is that a game ball is taken into the variable winning device 1, and this is more advantageous to the player. Therefore, the open / close patterns are “long open”, “normal open”, and “short open” when arranged in an order that is advantageous to the player.

  The open / close pattern of the symbol A corresponding to the symbol random number 0 is set to “normally open” for the first half game and the second half game of all round games. That is, in the case of the design random number 0, the opening / closing body 40; 40 is opened every 0.75 seconds in all round games until the round end condition is satisfied in each round game.

  In addition, the open / close pattern of symbol B corresponding to symbol random number 1 is set to “short open” for the first half of each round game from 9R to 12R, and “normally open” is set for the other games. It has become a thing. That is, in the first half game of each round game of 9R to 12R, the opening and closing body 40; 40 is opened for 0.45 seconds each time, and the opening and closing body 40; 40 is opened and opened for 0.75 seconds each time. This is repeated until a round end condition is satisfied in each round game. Therefore, in the open / close pattern of the pattern B, it is difficult to continue the rounds from the ninth round to the twelfth round.

  In addition, the open / close pattern of the symbol C corresponding to the symbol random number 2 is set to “short open” for the first half game of each round game from 5R to 8R, and “normal release” is set for the other games. It has become a thing. That is, in the first half game of each round game of 5R to 8R, the opening / closing body 40; 40 is opened for 0.45 seconds each time, and the opening / closing body 40; 40 is opened for 0.75 seconds each time. This is repeated until a round end condition is satisfied in the round game. Therefore, in the opening / closing pattern of the pattern C, it is difficult to continue the rounds from the fifth round to the eighth round. However, if the rounds are continued up to the ninth round, the possibility of continuing the rounds increases thereafter.

  In addition, the open / close pattern of the symbol D corresponding to the symbol random number 3 is set to “short open” for the first half game of each round game from 1R to 4R, and “normal release” is set otherwise. It has become a thing. In other words, in the first half game of each round game of 1R to 4R, the opening / closing body 40; 40 is opened for 0.45 seconds, and the opening / closing body 40; 40 is opened for 0.75 seconds otherwise. This is repeated until the round end condition is satisfied in the game. Therefore, in the opening / closing pattern of the pattern D, it is difficult to continue the rounds from the first round to the fourth round, but if the rounds are continued up to the fifth round, the possibility of continuing the rounds thereafter increases.

  In addition, the opening / closing pattern of symbol E corresponding to symbol random number 4 is set to “short open” for the first half game of each round game from 1R to 4R and the first half game of each round game from 5R to 8R. Otherwise, “normally open” is set. That is, in the first half game of each round game of 1R to 4R and the first half game of each round game of 5R to 8R, the opening / closing body 40; 40 is opened for 0.45 seconds, otherwise the opening / closing body 40; The operation of releasing 0.75 seconds is performed until a round end condition is satisfied in each round game. Therefore, in the opening / closing pattern of the pattern E, it is difficult to continue the rounds from the first round to the eighth round. However, if the rounds are continued up to the ninth round, the possibility of continuing the rounds increases thereafter.

  In addition, the open / close pattern of symbol F corresponding to symbol random number 5 is set such that “long open” is set for the first half game of all round games and “normal release” is set for the second half game. . In other words, in the first half game of all round games, the opening / closing body 40; 40 is opened for 1.2 seconds until the round end condition is satisfied in each round game. In this embodiment, the open / close pattern of the symbol F is highly likely to continue the round game up to 12 rounds.

  Here, as will be described in detail later, in each of the round games, in the first half game in which the opening and closing bodies 40; 40 are opened and closed for the first time to the tenth time, the course changing unit 75 is in an advantageous state, so the game ball Has a high probability of winning in the specific area V1 (V winning probability). On the other hand, in the second half game in which the opening / closing bodies 40; 40 are opened and closed 10th to 18th, the course changing unit 75 is in a disadvantageous state, so the V winning probability is lower than that in the first half game. Further, the longer the opening time of the opening / closing body 40; 40, the higher the possibility that a game ball will be taken into the variable winning device 1, so the V winning probability increases. Therefore, when the first half game of each round game is set to “Long Open”, the probability of continuing the round game with the V prize is the highest, and then the “Normal Open” wins the V game and the round game continues. The probability of playing is high, and “short opening” is the lowest probability that the round game will continue.

  Therefore, in this embodiment, the first half game of each round game of 9R to 12R is “short open” in the open / close pattern corresponding to symbol random number 1 compared to the open / close pattern corresponding to symbol random number 0. It is difficult for the ball to win the variable winning device 1. Therefore, the open / close pattern corresponding to symbol random number 1 has a lower probability of continuation of round games after the ninth round than the open / close pattern corresponding to symbol random number 0. In other words, symbol random number 1 has a lower probability of continuing up to 12 rounds than symbol random number 0, which is disadvantageous to the player. Similarly, in the open / close pattern corresponding to the symbol random number 2, since the first half game of 5R to 8R is “short open”, the probability that the round game will continue after the fifth round is lower than the symbol random number 1. Similarly, the probability that the round game will continue is lower in the opening / closing pattern corresponding to the symbol random number 3 than in the symbol random number 2, and the round game will continue in the opening / closing pattern corresponding to the symbol random number 4 than in the symbol random number 3. Probability is low.

  On the other hand, the open / close pattern corresponding to the design random number 5 is “long open” in the first half game of each round game, and the open times of the open / close bodies 40; 40 are “normal open” and “short open”. Since it is longer than “,” there is a high probability that the round game will continue after winning the V prize.

  Therefore, in this embodiment, the opening / closing pattern with the highest probability that a round game will continue to 12 rounds is symbol F, and in order, symbol A, symbol B, symbol C, symbol D, and so on up to the 12th round. The open / close pattern with a low probability is symbol E. Thus, in this embodiment, the opening time of the opening / closing body 40; 40 at the time of big hit is set to a different pattern, thereby making a difference in the probability that the round game will continue.

  Further, the sorting rotator 50 is stopped at the origin position during the round, and rotates only between rounds. The rotation operation between the rounds is an effect operation performed to make the player recognize that the next round is started, and the number of detection of the game ball by the entry ball detector 400A or 400B is 10 in total. When the count is reached, or when the total number of open / close bodies 40; 40 reaches 18 times, the rotation starts and stops at the origin before the next round starts.

  In addition, the jackpot game control unit 130 tilts the course changing unit 75 forward by energizing the solenoid Sol2 in the first half game in which the opening / closing bodies 40; 40 of the jackpot game are opened and closed from the first to the tenth game. The side drop port 71 is sealed so that the game ball rolling on the first stage 63 is easy to drop from the central drop port 70 to the second stage 64. That is, when the course changing portion 75 is tilted forward, the upper changing portion 77 protrudes forward on the side drop port 71; 71 to prevent the entry of the game ball. The game ball is likely to stay on the stage 63. Then, the staying game ball passes through the intake port 53 of the stopped sorting rotator 50 and falls from the central drop port 70 onto the second stage 64, so that it is easily taken into the specific region V1. Become.

  The tilt maintaining operation of the course changing unit 75 is continued until the opening / closing operation of the opening / closing body 40; 40 after the start of the round reaches 10 times, and the solenoid Sol2 is in a non-energized state from the 11th time to the 18th time. . Therefore, when the game ball is not taken in by the specific region V1 until the opening / closing operation of the opening / closing body 40; 40 reaches ten times, the game ball rolling on the first stage 63 thereafter is The possibility of falling from 71 increases.

  Here, a state in which the tilt maintaining operation of the course changing unit 75 is continued, that is, a state until the opening / closing operation of the opening / closing body 40; 40 after the start of the round reaches 10 times is an “advantageous distribution state” of the present invention. The state in which the tilt maintaining operation of the course changing portion 75 is not continued, that is, the state in which the opening / closing operation of the opening / closing body 40; 40 after the start of the round is from the 11th time to the 18th time is “disadvantageous” of the present invention. This corresponds to the “distributed state”.

  The jackpot game control unit 130 determines (continuous determination) whether or not a detection signal is input from the special prize detector 600 within a predetermined time after the round continues or after the round ends. In the case of a failure, the solenoid Sol1; Sol1 is driven again after a predetermined time has elapsed, and the next round is started. The process is repeated until the maximum number of continuations (12 rounds in this example) is reached, and when the maximum number of continuations is reached, the normal game is restored. On the other hand, if there is no detection signal input from the special winning detector 600, the big hit game is ended and the normal game state is restored even before the preset maximum number of continuations is reached (puncture processing). ).

  When the big hit game is finished (including the case where the big hit game is finished by the puncture process), the big hit game control unit 130 rotates the motor M and then stops at the timing when the positioning sensor 500 is turned on. . Thereby, in the normal gaming state, the sorting rotator 50 can always start rotating from the origin position. When the motor M stops, the functions of the first start detector 200A and the second start detector 200B become effective at that timing. That is, the functions of the first start detector 200A and the second start detector 200B are invalid during the big hit game, and become effective when the motor M stops after the final round of the big hit game is completed.

  As described above, according to the pachinko machine according to the present embodiment, the continuation probability of the round game can be changed by the opening / closing pattern of the opening / closing bodies 40; It is not necessary to control the operation of the members (sorting rotator 50, path changing unit 75) movable inside the variable winning device 1 differently. That is, the continuation probability of the round game can be changed only by controlling the operation of the opening / closing body 40; 40 without changing the control of the operation of each member in the variable winning device 1.

  In the above-described embodiment, when a game ball wins in the start winning opening 2A, 2B, the special symbol winning lottery unit 110 always wins, and the opening / closing body 40; 40 opens or closes once or twice. However, it is possible to prevent the opening / closing body 40; 40 from opening and closing when a lottery is provided in the lottery and the game ball is lost even if the game ball is won in the start winning opening 2A, 2B.

  In the above-described embodiment, the variation time of the special symbol is fixed to 0.2 seconds. However, a plurality of variation times are provided, and the variation time is set according to the lottery result by the special symbol success / failure lottery unit 110. It can also be set as the structure to determine. If it does in this way, since change can be made to the timing which the opening-and-closing body 40; 40 act | operates, game property will improve.

  In the above-described embodiment, the opening / closing pattern of the opening / closing bodies 40; 40 in the big hit game is “normally open”, “short open”, “long open” only in the first half game (advantageous distribution state) of each round game. ”Is set to one of the different patterns, but only in the second half of each round game (unfavorable distribution state), or both the first half game and the second half game are“ normally open ”,“ short open ” , “Long open” may be set to have different opening / closing patterns.

  In the above-described embodiment, the opening probability of the opening / closing body 40; 40 is changed to change the continuation probability of the round game. However, a plurality of opening / closing patterns having different opening / closing times of the opening / closing body 40; 40 are set. Thus, the continuation probability of the round game may be changed. For example, the opening / closing pattern corresponding to the pattern A has 18 opening / closing times of the opening / closing bodies 40; 40 in each round game, 15 times for the opening / closing pattern corresponding to the pattern B, and 12 times for the opening / closing pattern corresponding to the pattern C. As described above, even if the number of times of opening / closing the opening / closing body 40; 40 is changed during one round game, the number and timing of the game balls taken into the variable winning device 1 change. Will change. Of course, the opening / closing pattern can be set by combining the opening time of the opening / closing body 40;

  Further, in the above-described embodiment, the variable winning device 1 is configured to include the sorting member including the sorting rotator 50 and the course changing unit 75, but instead of this configuration, for example, the specific region V1. A route distribution member that distributes a game ball to any route by providing a high probability route for a game ball to invade with high probability and a low probability route for which the probability of entering the specific region V1 is lower than the high probability route. It is also possible to adopt a configuration provided with a sorting member. In this case, the state in which the route distribution member is in the posture for guiding the game ball to the high probability route is the advantageous distribution state of the present invention, and the posture in which the route distribution member guides the game ball to the low probability route. This is the unfavorable state of the present invention.

  In the above-described embodiment, the configuration in which the rotation speed of the motor M is changed midway between the start of rotation and the stop is shown. However, the configuration in which the rotation speed of the motor M is set to a predetermined constant from the start of rotation to the stop is shown. Anyway.

  Although the present invention has been described based on the embodiment, the technical scope of the present invention is not limited to the embodiment described above, and it will be apparent to those skilled in the art that various changes and improvements can be made. is there. Further, it is apparent from the scope of the claims that the embodiments added with such various changes and improvements can be included in the technical scope of the present invention.
