Further, as shown in FIG. 6, the upper end of the sub guide surface 24V is adjacent to the guide rail 12 so that the game ball does not pass between the upper end portion of the right side guide member 24R and the guide rail 12. ing. Further, the sub guide surface 24V and the lower end portion of the side start winning opening 40A are spaced apart from each other by a distance corresponding to one game ball. In the present embodiment, the side start winning opening 40A and the right side guide member 24 are integrally formed, and the base portion for attaching the integrally formed member to the game board 11 and the display frame body 23 are arranged. The mounting base portion (that is, the mounting wall 23F) to the game board 11 is disposed in the vicinity of the position where it is likely to buffer. The front side of the side start winning opening 40A and the right side guide member 24R is covered with a transparent cover 24K (see FIG. 4).

  As shown in FIG. 2, a windmill 19 is provided at a lower position in the left side region of the display frame 23 in the game region R1. The windmill 19 is rotatably supported on a support shaft (not shown) that stands up from the game board 11, and freely rotates when the game ball collides. A left side guide member 24L is provided below the windmill 19. Similarly to the right side guide member 24R, the left side guide member 24L is made of resin, and includes a sub guide surface 24W that is gently inclined toward the center side of the game area R1. Further, below the left side guide member 24L, a reserved number display unit 36 having a plurality of (for example, 10) LEDs and a normal symbol display unit 36F composed of 7 segment LEDs are provided. In the present embodiment, the sub guide surface 24W of the left side guide member 24L and the sub guide surface 24V of the right side guide member 24R have a symmetrical shape.

  In the game area R1, a plurality of nails 11N are erected over the entire outer area of the display frame 23. The nail 11N is connected in several places to form a guide nail group that guides the flow direction of the game ball. As a typical guide nail group, main guide nail groups 11U and 11U for guiding a game ball to the central special prize opening 15 are provided on the left and right sides of the central special prize opening 15 in the lower region of the display frame 23. ing. The main guide nail groups 11U and 11U are arranged so as to be inclined downward from the left and right end portions toward the central prize winning opening 15 by 16 nails 11N on each of the left and right sides, for example. Then, the upper surface of the nail 11N constituting the main guide nail group 11U is set as the main guide surface 11V, and the game ball rolls on the main guide surface 11V and is guided to the central prize winning opening 15.

  Further, the side start winning opening 40A described above is disposed on an extension line L1 in the arrangement direction of the right main guide nail group 11U. More specifically, as shown in FIG. 6, when the game board 11 is viewed from the front, the extension line L1 of the main guide surface 11V in the right main guide nail group 11U crosses the opening of the side start winning opening 40A. Is arranged.

  Further, the sub guide surface 24V of the right side guide member 24R is gently inclined from the arrangement direction of the main guide nail group 11U toward the upper end portion of the right main guide nail group 11U. More specifically, as shown in FIG. 6, when the game board 11 is viewed from the front, the upper end portion of the main guide surface 11V of the right main guide nail group 11U and the lower end portion of the sub guide surface 24V are brought into contact with each other. The sub guide surface 24V is inclined at a gentle angle closer to the horizontal than the inclination at the upper end portion of the main guide surface 11V (for example, an inclination angle of 27 degrees with respect to the horizontal line) and inclined toward the upper end portion of the main guide surface 11V. Yes.

  Here, the inclination angle of the main guide surface 11V will be described in detail. As shown in FIGS. 7 and 8, generally, the diameter of the game ball is 11 mm, and the diameter of the nail 11N is 1.85 mm. In consideration of the head portion of the nail 11N and the nailing machine, the distance between the nails (the distance from the center of the nail 11N to the center) of about 5.3 to 5.5 mm is required. In FIG. 7, the head portion of the nail 11N is indicated by a two-dot chain line.

  Here, for example, the case where the distance between the nails is 5.5 mm and the inclination angles are 25 degrees, 26 degrees, and 27 degrees will be described. When the inclination angle is 25 degrees, as shown in FIG. 7A, the center of gravity of the game ball is behind the center of the lower nail 11N out of the two nails 11N in contact with the game ball. It is located (above the inclination). That is, there is a possibility that the game ball stops between the nails because the center of gravity of the game ball is located between the two nails 11N forming the space between the nails.

  On the other hand, when the inclination angle is set to 26 degrees, as shown in FIG. 7B, the center of gravity of the game ball is directly above the center of the lower nail 11N out of the two nails 11N contacting the game ball. It is located on the front side (lower with respect to the inclination). That is, the center of gravity of the game ball is positioned outside the two nails 11N that constitute the gap between the nails, so that the game ball always rolls downward without stopping between the nails. If the inclination angle is 27 degrees, the center of gravity of the game ball is located further forward (downward with respect to the inclination) than the inclination angle of 26 degrees, as shown in FIG. 8A. For this reason, in this embodiment, the inclination angle of the main guide surface 11V (main guide nail group 11U) is set to 27 degrees or more in order to surely flow the game ball down.

  In order to secure a region above the main guide nail group 11U, it is preferable to reduce the inclination angle of the main guide surface 11V. However, when the guide surface is composed of only the guide nails, even if the inclination angle is set to the minimum required 27 degrees, the side start winning opening is located on the extension line L1 of the main guide surface 11V in the right main guide nail group 11U. Since the opening of 40A is arranged, the nail 11N cannot be hit. On the other hand, in the present embodiment, since the guide surface is configured by the continuously smooth surface sub guide surface 24V formed on the right side guide member 24R, the inclination angle is reduced to, for example, 5 degrees. However, it is possible to guide the game balls toward the main guide nail group 11U and to suppress clogging of the balls. When the inclination angle is 5 degrees, as shown in FIG. 8B, the center of gravity of the game ball is close to the middle position between the two nails 11N that contact the game ball, and the game ball stops between the nails. The possibility increases.

  Further, as shown in FIG. 2, the sub guide surface 24W of the left side guide member 24L also has a main guide toward the upper end of the left main guide nail group 11U, similarly to the sub guide surface 24V of the right side guide member 24R. The nail group 11U is gently inclined from the arrangement direction.

  As shown in FIG. 6, a side guide nail group 11 </ b> S is provided diagonally to the upper right of the rotation area of the rhinodomain movable door 37 </ b> T. The side guide nail group 11S is composed of, for example, six nails 11N, and is arranged so as to guide the game balls to the open rhinodomain movable door 37T.

  In addition to the main guide nail group 11U and the side guide nail group 11S described above, for example, a guide nail group that guides the flow direction of the game ball toward the side start winning port 40A above the side start winning port 40A. Is provided. A guide nail group for guiding the game ball toward the windmill 19 is also provided above the windmill 19.

  By the way, in the pachinko gaming machine 10 of the present embodiment, when a game ball enters the above-mentioned center start winning opening 14, start gate 18, and side start winning opening 40A, the following three types of lotteries are performed, and the player can enjoy it. I can do it.

  Specifically, as the first type of lottery, every time a game ball enters the central start winning opening 14, a determination is made as to whether or not to execute the “first jackpot game”. The result is displayed on the liquid crystal display screen 34. On the liquid crystal display screen 34, usually three left, middle and right special symbols 13A, 13B and 13C are displayed side by side. Each of these special symbols 13A, 13B, and 13C is composed of, for example, a plurality of types that express numbers from “0” to “11”. Usually, each special symbol 13A, 13B, and 13C has a predetermined value. Kinds of things are stopped. Then, when a game ball enters the central start winning opening 14 and the winning / failing determination is made, these three special symbols 13A, 13B, and 13C are scrolled up and down, and after a predetermined time, for example, left The special symbols 13A, 13B, 13C are stopped and displayed in the order of right, middle. At this time, if the result of the game success / failure determination is “big hit”, for example, all of the special symbols 13A, 13B, and 13C are the same symbol, that is, a rough eye.

  When the left and right special symbols 13A and 13C are stopped and displayed with the same symbol and only the middle special symbol 13B is variably displayed, a predetermined reach effect image (for example, a character image) is displayed on the liquid crystal display screen 34. The When the game button 27C provided at the lower left corner of the front frame 10Z is pressed, images (for example, character images) other than the special symbols 13A, 13B, and 13C that are variably displayed on the liquid crystal display screen 34 are arbitrarily selected by the player. It can be stopped at the timing.

  When the special symbols 13A, 13B, and 13C enter the central start winning opening 14 during the variable display or “hit state” on the liquid crystal display screen 34, up to four winning balls are stored as holding balls, The number of stored memories (the number of held balls) is displayed using the upper half LEDs of the above-described number-of-holds display section 36. When the special symbols 13A, 13B, and 13C are stopped or displayed, or the “hit state” is ended, the number of reserved memories is reduced by one, and the special symbols 13A, 13B, and 13C are again displayed after being variably displayed. The game success / failure determination result is displayed. Here, the probability of winning the jackpot is set to 1/399, for example. If the result of the game success / failure determination is “big hit”, the central movable door 15T of the central big prize opening 15 is opened for a predetermined period.

  As described above, when a game ball enters the central start winning opening 14, whether or not to open the central large winning opening 15 is determined instead of simply opening the central large winning opening 15. In addition, since the central movable door 15T is opened and the central special prize opening 15 is opened for a predetermined period, the player can be entertained by determining whether or not it is successful. Then, an interest can be given to whether or not a game ball enters the central start winning opening 14, and after a game ball enters the central start winning opening 14, You can be interested in whether or not to enter the ball.

  As a second type of lottery, every time a game ball passes through the inside of the start gate 18, a preliminary determination as to whether or not to operate the advance / retreat guide piece 40Z is performed, and the result of the preliminary determination is displayed as a normal symbol. It is displayed on the part 36F. Specifically, when the game ball passes through the inside of the start gate 18, after the numerical symbols composed of the numbers “0” to “9” are variably displayed over the predetermined period on the normal symbol display portion 36 </ b> F, A predetermined numerical symbol is stopped and displayed. At this time, when the stop-displayed number is an odd number, it is “win”, and when it is an even number, it is “out”. Here, the probability of winning is set to 99/100, for example.

  When the result of the preliminary success / failure determination is successful, the side sub movable door 40T is opened and the advance / retreat guide piece 40Z is advanced over a predetermined period (for example, 0.088 seconds), and the game ball is placed in the side start winning opening 40A. You can enter the ball.

  When the game symbol passes through the inside of the start gate 18 while the numeric symbol is variably displayed or “winning state” in the normal symbol display unit 36F, up to four winning balls are stored as reserved balls, The number of reserved memories (the number of reserved balls) is displayed using the lower half LEDs of the above-described number-of-holds display section 36. When the numerical symbol is stopped or the “hit state” is finished, the number of reserved memories is reduced by one, and after the numerical symbol is variably displayed, it is stopped and displayed, and the preliminary determination result is displayed.

  As described above, the side start winning opening 40A is normally closed, and the game ball can enter due to the game ball passing through the inside of the start gate 18. It is possible to be interested in whether or not the game ball passes, and after the game ball passes through the inside of the start gate 18, it is interested in whether or not the game ball enters the side start winning opening 40A. Can be made. Moreover, when the game ball passes through the inside of the start gate 18, whether or not to open the side start winning opening 40A is determined instead of simply opening the side start winning opening 40A. Since the movable door 40T is opened and the advancing / retreating guide piece 40Z is projected to open the side start winning opening 40A for a predetermined period, the player can be entertained by determining whether or not he / she is successful.

  As a third type of lottery, every time a game ball enters the side start winning opening 40A, it is determined whether or not to execute the “second jackpot game”, and the result of the determination is displayed on the liquid crystal display screen. 34. The display method of determination on the liquid crystal display screen 34 is the same as the display method of the determination result of “first jackpot game” as described above, such as decoration colors and patterns for the special symbols 13A, 13B, and 13C, and the liquid crystal The background images and the like of the special symbols 13A, 13B, and 13C on the display screen 34 are different from the case of the determination result of “first jackpot game”. Here, the probability of being a big hit (corresponding to the “second hit” of the present invention) is 1/399, and the probability of being a small hit (corresponding to the “first hit” of the present invention) is 398/399. Is set to That is, when a game ball enters the side start winning opening 40A, a big hit or a small hit is won. If the determination result of the game is “big hit”, the central movable door 15T of the central big prize opening 15 is opened for a predetermined period. If the special symbols 13A, 13B, 13C enter the side start winning opening 40A while the special symbols 13A, 13B, 13C are variably displayed on the liquid crystal display screen 34 or in the “hit state”, the winning balls are not held.

  Here, when the game determination result is a small hit, the side domain movable door 37T at the side big prize opening 37A is opened, and the regulating piece 38K is retracted to the inside about one second after the side domain door 37T is opened. The continuous winning opening 37Z is opened for 0.388 seconds. Here, when the period between the opening and closing of the Sai domain movable door 37T is referred to as a “round”, one round ends when the opening time of the Sai Domain movable door 37T reaches 1.6 seconds. . When a game ball enters the continuous winning opening 37Z, the next round is continuously executed after the round ends. Further, the “small hit state” (the opening operation of the rhino domain movable door 37T) is continued up to, for example, 16 rounds. After the “small hit state” is completed, the “short time state” is set with a probability of 25/50 (41/50 in the short time). If the game ball that entered the side big prize opening 37A does not enter the continuous prize opening 37Z, it will end in the first round, and if it enters the continuous prize opening 37Z, the side will start from the next round. Without opening / closing the main movable door 37T, it becomes a “hit state”, and the central movable door 15T of the central big prize opening 15 is opened / closed for a predetermined period, and the remaining rounds (for example, 15 rounds) are executed.

  Thus, the side domain movable door 37T of the side big prize opening 37A is normally closed, so that the game ball can enter due to the game ball entering the side start prize opening 40A. It is possible to make the player interested in whether or not a game ball enters the side start winning opening 40A. Moreover, when a game ball enters the side start winning opening 40A, it is determined whether to open the side domain movable door 37T of the side large winning opening 37A or the central movable door 15T of the central large winning opening 15, The side movable door 37T is opened for a predetermined period in the case of a small hit, and the central movable door 15T is opened for a predetermined period in the case of a big hit, so that the player can be entertained by the determination. In other words, after a game ball has entered the side start winning opening 40A, it can be interested whether or not the game ball enters the central grand prize opening 15 or the side large winning opening 37A.

  Furthermore, since the central movable door 15T of the central grand prize opening 15 is opened for a predetermined period due to the game ball having entered the side special prize opening 37A, the game ball enters the side special prize opening 37A. It is possible to be interested in whether or not to play, and after a game ball has entered the side big prize opening 37A, it is interested in whether or not the game ball that has entered enters the continuous prize opening 37Z. be able to.

  As described above, the central grand prize opening 15 is configured to be opened and closed by the central movable door 15T, and a game ball enters the central start prize opening 14 provided on the upper side of the central big prize opening 15 to determine whether or not When the determination is a win and when the game ball enters the side start winning opening 40A and the determination is a big win (second win), the central movable door 15T of the central big win 15 is predetermined. Open over time. Here, when the period from when the central movable door 15T is opened until it is closed is referred to as “round”, for example, in one round, the opening time of the central movable door 15T has reached a predetermined time (30 seconds), or The process ends when any one of the predetermined number (10) of the game balls has entered the central prize winning opening 15 is satisfied first. Further, the “big hit state” (the opening operation of the central movable door 15T) is continued up to, for example, 15 rounds. Then, after the “big hit state” is completed, the “short time state” is set with a probability of 25/50 (41/50 during the short time).

  In the “short time state”, the opening time of the side sub movable door 40T and the advancement time of the advance / retreat guide piece 40Z are increased from, for example, 0.088 seconds in the normal state to 1.7 seconds, and the number of times is also once. There will be 3 more games. By maintaining the advantageous state of “short time state”, it becomes easier to enter the side start winning opening 40A during the “short time state”, so that it becomes easier to obtain a winning ball than in the normal gaming state, It will be in the state which suppresses decrease of. And it can play a game until the next jackpot, suppressing reducing a ball.

  The description regarding the configuration of the pachinko gaming machine 10 according to the present embodiment has been described above. Next, the effect of the pachinko gaming machine 10 of this embodiment will be described. When a plurality of game balls are sequentially driven into the game area R1 by operating the operation knob 28, some of the game balls flow down from the upper area of the display frame 23 to the left side area in the game area R1. . Then, these game balls are guided by the wind guide 19 and the sub guide surface 24W of the left side guide member 24L and flow down to the lower region, and a part of another game ball is a left side region of the display frame 23. Then, it passes through the warp rod 39, rolls on the stage 23S, and flows down to the lower region of the display frame 23. During this time, some of the game balls are awarded to the central start winning opening 14 and the general winning openings 20 and 21, and the winning balls are paid out to the upper plate 27A. In addition, when winning at the central start winning opening 14, a lottery (whether or not is determined) whether or not to open the central movable door 15T is performed. If the lottery result is a win, the central movable door 15T is opened and the display frame body 23 is opened. Many of the game balls flowing down the lower area of the can enter the central grand prize opening 15.

  In addition, a part of the game balls that are driven into the game area R1 pass through a narrow area between the upper right portion of the display frame 23 and the guide rail 12 one by one, and a side area of the display frame 23 To the upper end of Then, the game balls flow down one by one through the side area of the display frame 23 through the gateway R2. Then, at the upper end portion of the right side region of the display frame body 23, the game ball is first divided into whether or not it passes through the inside of the start gate 18. Here, when the game ball passes through the inside of the start gate 18, a lottery is performed as to whether or not the side start prize opening 40A can be won. If the lottery result is a win, a predetermined period (for example, a normal game) In the state, it is possible to win the side start winning opening 40A once for 0.088 seconds and three times for 1.7 seconds in the short-time gaming state. When winning the side start winning opening 40A, a lottery is performed to determine whether to open the rhinodomain movable door 37T or the central movable door 15T. Then, when the central movable door 37T is opened and the central movable door 15T is opened after the continuous winning opening 37Z is opened or the central movable door 15T is directly opened by lottery, a large amount of game balls are entered into the central large winning opening 15. The ball can be entered and many prize balls can be obtained. Further, it is determined whether to enter the normal gaming state or the short-time gaming state after the jackpot state ends based on the winning at the side start winning port 40A, and the gaming state determined after the jackpot state ends due to the continuous winning port 37Z In the case of a configuration that shifts to (normal gaming state or short-time gaming state), even if the winning timing is measured so that the continuous winning opening 37Z is not won when the normal gaming state is determined, By providing the rhino domain movable door 37T at a position where the distance from launching to winning is long, the winning timing for the continuous winning opening 37Z is difficult to measure.

  When the side special winning opening 37A is open, the side guide nail group 11S serves as a guide for entering the game ball into the side special winning opening 37A. Further, most of the game balls that have not entered the side large winning opening 37A and the side start winning opening 40A are received by the sub guide surface 24V of the right side guide member 24R, and the main guide nail group 11U is received from the sub guide surface 24V. Is guided to the main guiding surface 11V, and is further guided to the central special prize opening 15 by the main guiding surface 11V. At this time, if the central movable door 15T is open, the game ball guided to the sub guide surface 24V of the right side guide member 24R and the main guide surface 11V of the main guide nail group 11U has a high probability of receiving the central prize opening 15. To win a prize.

  As described above, in the pachinko gaming machine 10 according to the present embodiment, not only the area below the display frame body 23 but also the side area of the display frame body 23 in the game area R1 can be used effectively to entertain the player. Can do. Further, the side area of the game board 11 can be effectively used because the sub guide surface 24V of the right side guide member 24R is gently inclined from the arrangement direction of the main guide nail group 11U as described above. This is because the side region of the display frame 23 is disposed below and the side start winning opening 40A is disposed on the extension line L1 in the arrangement direction of the main guide nail group 11U.

  That is, in the pachinko gaming machine 10 according to the present embodiment, the side region of the display frame body 23 is conventionally increased by gently tilting the sub guide surface 24V of the right side guide member 24R from the arrangement direction of the main guide nail group 11U. It could be wider in the vertical direction. Thereby, the start gate 18 and the side start winning opening 40A can be arranged side by side vertically. Then, by arranging the side start winning opening 40A on the extended line L1 in the arrangement direction of the main guide nail group 11U, it is a horizontal area where it is difficult to provide a large winning opening with a horizontal width such as the central movable door 15T. Even in such a case, it is possible to secure an area where the side special winning opening 37A can face, and it is possible to open and close the side special winning opening 37A by the side domain movable door 37T that rotates in the area. The side area of the body 23 can be used effectively to entertain the player.
