According to the invention of claim 3, when the game ball flowing down the front surface of the game board is received by the drive door, it is guided by the drive door and enters the opening / closing entrance from the front surface of the game board.

[Invention of claim 4]
According to the invention of claim 4, the opening / closing entrance and the drive door are divided into two on the left and right with the central passageway in between. Since the central passage is provided on a vertical line passing through the gate, the game ball that has dropped vertically from the gate flows down on the central passage. As a result, even when the opening / closing entrance is in an open state, the game ball that has dropped vertically from the gate can flow down to the opening / closing entrance without entering the opening / closing entrance.

[Invention of claim 5]
According to the fifth aspect of the present invention, when the opening / closing entrance is in an open state, the game ball that has flowed vertically downward from the gate comes into contact with the shut-off drive unit and the flow direction is changed. Thereby, the game ball dropped vertically from the gate can flow down to the opening / closing entrance without entering the opening / closing entrance. In addition, when the opening / closing entrance is closed, the shut-off drive unit retreats from the vertical line connecting the gate and the open / close entrance, so that the game ball flowing down vertically from the gate comes into contact with the shut-off drive unit. No, the game ball flows down vertically. Thereby, the flow path of the game ball after passing through the gate can be made different depending on whether the opening / closing entrance is in an open state or a closed state.

[Invention of claim 6]
According to the invention of claim 6, the game ball that has flowed vertically downward from the gate when the opening / closing entrance is in an open state passes through a door passage formed in the drive door without being received by the drive door. It flows down to the opening and closing entrance. Thereby, the game ball dropped vertically from the gate can flow down to the opening / closing entrance without entering the opening / closing entrance.

[Invention of Claim 7]
According to the seventh aspect of the present invention, it is possible to reliably prevent a game ball from entering the opening / closing entrance when the opening / closing entrance is closed.

[Invention of Claim 8]
According to the eighth aspect of the present invention, the game ball that rolls toward the door passage when the opening / closing entrance is in a closed state collides with the ball prevention protrusion, so that the game ball passes through the door passage. Thus, entering the opening / closing entrance is prevented.

[Invention of claim 9]
According to the ninth aspect of the present invention, the game ball that has flowed vertically downward from the gate when the entrance is in a closed state collides with the collar that covers the upper part of the door passageway, thereby causing the front side of the door passageway to pass. Since it becomes difficult to pass, it becomes difficult for a game ball to enter the opening / closing entrance through the door passage.

[Invention of Claim 10]
In the configuration of claim 10, the game ball that has passed through the gate is not allowed to enter the opening / closing entrance in the portion where the synthetic resin member is arranged, that is, the vertical line connecting the gate and the opening / closing entrance. The obstacle nail cannot be placed. This is because when the obstacle nail is struck, the synthetic resin member is broken and the obstacle nail cannot be fixedly arranged. The game balls that fall vertically on the accessory device after passing through the gate are difficult to enter the opening / closing entrance by the entrance restraining means regardless of the obstacle nail. Will increase.

[Invention of Claim 11]
According to the eleventh aspect of the present invention, the opening / closing entrance is opened at the time of hitting the game, and game balls that have not passed through the gate can enter the opening / closing entrance. Can be held.

Hereinafter, a first embodiment of a pachinko gaming machine to which the present invention is applied will be described with reference to FIGS. As shown in FIG. 2, the pachinko gaming machine 10 of the present embodiment is provided with, for example, a wooden game board 11. The game board 11 is formed with a substantially circular game area R1 surrounded by guide rails 12, and a display device 13 is provided at the center of the game area R1. Below the display device 13 in the game area R1, a special symbol start gate 17 (corresponding to the “gate” of the present invention), a special symbol start winning port 40, and a large winning port 50 (the “opening / closing ball opening” of the present invention). ) And the out port 16 are provided side by side at intervals from the top. In addition, wind turbines 19 and 19 are provided on the left and right sides of the game area R1 with the display device 13 interposed therebetween, and side lamps having an arc shape along the guide rails 12 are provided outside the wind turbines 19 and 19. 22 and 22 are provided. Below the side lamps 22, 22, an upper side winning port 20 and a lower side winning port 21 are provided along the guide rail 12. Also, normal symbol start gates 18 and 18 are disposed between the upper side winning prize ports 21 and 21 and the special symbol start gate 17. Furthermore, a plurality of obstacle nails are erected over the entire game area R1.

  As shown in FIG. 1, in the pachinko gaming machine 10, a decorative lamp 30 that protrudes to the front side of the game board 11 is provided above the game board 11. Further, below the game board 11, an upper plate 27A and a lower plate 27B are provided in two upper and lower stages. Then, by operating the operation knob 28 provided at the right end portion of the lower plate 27B, the game ball accommodated in the upper plate 27A is blown out toward the game board 11. Further, if the button 29 provided on the upper plate 27A is pressed, the game ball moves from the upper plate 27A to the lower plate 27B and is accommodated. Furthermore, a pair of speakers 99, 99 are provided on both sides of the upper plate 27A.

Next, each required part will be described.
The upper side winning port 20 and the lower side winning port 21 are both open upward with an opening width that allows one game ball to be won. The game balls that have won the side winning ports 20 and 21 are collected on the rear side of the game board 11. Further, when a game ball is won in each side winning opening 20, 21, for example, ten prize balls are paid out to the upper plate 27A for one (one) win.

  The normal symbol starting gate 18 has a gate structure that is open up and down, and allows game balls to pass through. An inclined piece 25 erected at a right angle from the game board 11 is provided immediately below the lower end opening of the normal symbol starting gate 18. The upper surface of the inclined piece 25 is inclined so as to descend toward the special symbol start winning opening 40. As a result, the game ball that has passed through the normal symbol starting gate 18 falls on the upper surface of the inclined piece 25 and is guided by the inclined piece 25 to flow downward diagonally (specifically, the big winning opening 15).

  The display device 13 includes a decoration frame 23 fitted in a through hole (not shown) formed in the game board 11, and a display 34 made of a TFT-LCD module is provided at the back of the decoration frame 23.

  As shown in FIG. 1, three special symbols 13A, 13B, and 13C are displayed on the display 34 side by side. Each special symbol 13A, 13B, 13C is composed of ten kinds of numerical symbols from “0” to “9”, and usually one of the special symbols 13A, 13B, 13C has one numerical symbol. Stop is displayed. When a game ball wins a special symbol starting gate 17 or a special symbol starting winning port 40 described later, the special symbols 13A, 13B, and 13C are scrolled up and down and displayed in a variable manner. The variation display of the special symbols 13A, 13B, and 13C corresponds to the “symbol game” of the present invention, and the start of the variation display corresponds to the “game bonus” of the present invention.

  After a predetermined time from the scrolling of each special symbol 13A, 13B, 13C, for example, the left special symbol 13A, the right special symbol 13C, and the middle special symbol 13B are stopped in order and the predetermined symbol is stopped and displayed. . Here, for example, when all of the special symbols 13A, 13B, and 13C that have been stopped and displayed have the same number (so-called “spotted”), a so-called “big hit game” is executed, which will be described later. Many game balls can be awarded to the big winning opening 50.

  In the display device 13, an ordinary symbol display unit 24 is provided on the upper side portion of the decorative frame 23. The normal symbol display unit 24 displays two normal symbols 24A and 24B as shown in FIG. The normal symbols 24A and 24B are composed of numeric symbols “0” to “9”. When the normal symbol start switch provided in the normal symbol start gate 18 detects the passing of the game ball, the determination is made, for example, , “0” to “9” are variably displayed over a predetermined period, and then the predetermined number is fixedly displayed. For example, when the regular symbols 24A and 24B that are confirmed and displayed are odd numbers, a “small hit game” is performed in which a game ball can enter a special symbol start winning opening 40 described later. The symbols displayed on the normal symbol display unit 24 are not limited to numerals, and may be alphabets or symbols.

  Now, the special symbol starting gate 17, the special symbol starting winning port 40, and the big winning port 50, which will be described in detail later, are integrally provided in the accessory device 100 shown in FIG. The accessory device 100 is inserted into an attachment hole 11A (see FIG. 4) formed through the game board 11 from the front side of the game board 11, and the peripheral edge of the base 101 is placed on the front surface of the game board 11, for example. It is fixed with a screw or the like. The base portion 101 has a flat plate shape, and the front surface is a flat surface parallel to the front surface of the game board 11. The base portion 101 closes the mounting hole 11A of the game board 11 and constitutes a part of the front surface of the game board 11. A special symbol start gate 17 is provided on the front surface of the base portion 101, and a special symbol start winning opening 40 and a large winning opening 50 penetrating the base portion 101 are provided below the special symbol starting gate 17 in the base portion 101. Are formed side by side.

  A pair of obstacle walls 103 and 104 are formed on both sides of the base portion 101 with the special symbol start winning opening 40 and the big winning opening 50 interposed therebetween. The obstacle walls 103 and 104 bulge from the front surface of the base portion 101 (see FIG. 4). Of the obstacle walls 103 and 104, the opposing surfaces 103T and 104T facing each other with the winning ports 40 and 50 interposed therebetween are flat surfaces perpendicular to the surface of the game board 11 and along the sides of the winning ports 40 and 50. The front surfaces 103Z and 104Z are flat surfaces parallel to the game board 11 surface (see FIG. 5). Further, the upper surface 103J of the obstacle wall 103 provided on both sides of the special symbol start winning opening 40 is inclined so as to descend toward the special symbol start winning opening 40, and is provided on both sides of the special winning opening 50. The upper surface 104J of the obstacle wall 104 is inclined so as to descend toward the special winning opening 50. The front side of the game board 11 is covered with a glass plate (not shown). The distance between the front surface of the game board 11 (base board 101) and the glass plate is slightly larger than the diameter of the game ball (for example, 11 mm). Further, the gaps between the front surfaces 103Z and 104Z of the obstacle walls 103 and 104 and the glass plate are smaller than the diameter of the game ball. Accordingly, the game ball flows down through the portion of the base plate 101 where the obstacle walls 103 and 104 are not formed, and does not pass through the front side of the front surfaces 103Z and 104Z of the obstacle walls 103 and 104.

  By the way, since the base part 101 of this embodiment is a product made from a synthetic resin, the obstruction nail is not planted in the front surface of the part to which the accessory apparatus 100 was attached among the game boards 11. FIG. Therefore, the game balls passing through the portion between the special symbol start gate 17 and the special symbol start winning port 40 and the portion between the special symbol start winning port 40 and the big winning port 50 collide with the obstacle nail and flow downward. Will not change. Here, the reason why the obstacle nail is not provided is that the portion of the game board 11 to which the accessory device 100 is attached is provided with a wooden game board 11 in which an attachment hole 11A is formed so that the obstacle nail can be implanted. This is because if the obstacle nail is directly struck to the accessory device 100, the base portion 101 made of synthetic resin is broken, and the obstacle nail cannot be fixed to the base portion 101.

  A back unit 102 is provided on the back side of the base unit 101. The back unit 102 has a game ball sensor 62, 75, 85 that detects a game ball that has passed through the special symbol start gate 17 and a game ball that has entered each of the winning ports 40, 50, and a ball that has entered the special symbol start winning port 40. A collection passage 76 for guiding the played game balls to the back side of the game board 11, solenoids 43, 53 for opening / closing a start opening / closing door 41 and a special prize opening opening / closing door 51, which will be described later, are provided.

  First, the special symbol start gate 17 will be described. The special symbol starting gate 17 has a gate-shaped structure opened up and down. Specifically, the special symbol start gate 17 includes a pair of side wall portions 60 and 60 (corresponding to the “leg portions” of the present invention) standing upright from the game board 11 (base portion 101). The front ends of 60 and 60 are connected by a decorative plate 61 (corresponding to the “connecting member” of the present invention). The pair of side wall portions 60, 60 are arranged on the left and right sides with a space slightly larger than the diameter of the game ball, and the decorative plate 61 is larger than the diameter of the game ball from the front surface of the game plate 11 (base portion 101). Arranged at spaced positions. And the upper end opening 17J and the lower end opening 17K of the special symbol starting gate 17 have the same opening width and are arranged in the vertical direction.

  A game ball sensor 62 is provided at an intermediate position in the vertical direction of the special symbol start gate 17. The game ball sensor 62 has a long plate shape, for example, is inserted into the insertion hole 101S formed through the base portion 101 from the back side of the base portion 101, and a part thereof is disposed inside the special symbol starting gate 17. (See FIG. 5). A substantially circular opening 63 penetrating in the vertical direction is formed in a portion of the game ball sensor 62 disposed inside the special symbol start gate 17. The substantially circular opening 63 has an opening size through which exactly one game ball can pass. The game ball enters from the upper end opening 17J of the special symbol start gate 17, and is detected by the game ball sensor 62 when passing through the substantially circular opening 63, and falls vertically from the lower end opening 17K.

  As shown in FIG. 5, the upper edge portion of the decorative plate 61 constituting the special symbol start gate 17 is tapered so as to descend toward the inside of the special symbol start gate 17. This makes it easier for a game ball that has fallen to the upper edge of the decorative board 61 to enter the special symbol start gate 17. Moreover, as shown in FIG. 3, the upper side part from the game ball | bowl sensor 62 is comprising the uneven | corrugated shape among the inner side surfaces 60T and 60T of the side wall parts 60 and 60. As shown in FIG. This uneven shape reduces the speed of the game ball that has entered the special symbol start gate 17 so that the game ball sensor 62 does not fail to detect the game ball. The above is the description of the special symbol start gate 17.

  As shown in FIG. 3, a special symbol start winning opening 40 is provided at a position below the special symbol start gate 17 in the base portion 101. The special symbol start winning opening 40 has a horizontally long rectangular shape. The width of the special symbol start winning opening 40 is larger than the lower end opening of the special symbol start gate 17. And as shown in FIG. 3, the special symbol start gate 17 is arrange | positioned on the vertical line E which passes along the center part in the horizontal width direction (left-right direction in FIG. 3) of the special symbol start winning opening 40. As shown in FIG. The game ball that has flowed down the front of the game board 11 and entered the special symbol start winning opening 40 is guided to the back side of the game board 11. Further, when a game ball enters the special symbol start winning opening 40, for example, four prize balls are paid out for each (one) entry.

  As shown in FIG. 5, a ball receiving room 70 in which a game ball can roll is formed on the back side of the special symbol start winning opening 40. The ball receiving room 70 is slightly narrower than the special symbol start winning opening 40 and has a depth substantially equal to the diameter of the game ball. In the ball receiving room 70, a ball receiving port 72 through which a game ball can pass is formed in one side portion (right end portion in FIG. 3) of the back wall 71 facing the special symbol start winning port 40. The ball receiving port 72 has an arch shape that allows a single game ball to pass through. Here, the bottom surface 70 </ b> S of the ball receiving room 70 is inclined so as to descend toward the ball receiving port 72. Specifically, the bottom surface 70S is lowered from the left end portion toward the right end portion, and the right end portion is lowered toward the back side (see FIG. 5). Thereby, the game ball transferred into the ball receiving room 70 from the special symbol start winning opening 40 is smoothly guided to the ball receiving port 72.

  The ball receiving port 72 communicates with a back side chamber 73 extending further to the back side than the ball receiving room 70. The bottom surface 73S of the back side room 73 is flush with the bottom surface 70S of the ball receiving room 70, and is inclined so as to descend toward the back side. A game ball sensor 75 is provided below the back room 73. The game ball sensor 75 has a ball detection port 74 penetrating in the vertical direction. The ball detection port 74 is a circular hole having a diameter slightly larger than the diameter of the game ball.

  A triangular protrusion 77 projecting downward toward the back side is formed on the ceiling portion of the back side room 73. A game ball that has been vigorously transferred from the ball receiving room 70 to the back room 73 can change the rolling direction by coming into contact with the triangular protrusion 77 and fall from the ball detection port 74.

  By the way, the game ball that has entered the special symbol start winning opening 40 is detected by the game ball sensor 75. In other words, the game ball is not detected when it passes through the special symbol start winning opening 40, but passes through the special symbol start winning opening 40, and passes through the ball receiving room 70 and the back side room 73 and passes through the ball detection opening 74. Detected when passing. As a result, there is a slight time difference between the game ball passing through the special symbol start winning opening 40 and being detected by the game ball sensor 75. The game ball that has passed through the ball detection port 74 is collected in a pachinko hall by a collection passage 76 provided on the back side of the game board 11 (specifically, the back side unit 102).

  The special symbol start winning opening 40 is provided with a start opening / closing door 41. The start opening / closing door 41 has a rectangular horizontally long strip shape that is almost the same size as the special symbol start winning opening 40, and the lower side portion 41K is horizontally passed between both sides of the special symbol starting winning opening 40. It is supported by a rotating shaft 42 (see FIG. 7). Thereby, the start opening / closing door 41 is rotatable in a plane orthogonal to the base portion 101 of the accessory device 100.

  The start opening / closing door 41 is always parallel (vertical direction) to the front surface of the base 101 (the state shown in FIGS. 5 and 7) so that a game ball cannot enter the special symbol start winning opening 40. The special symbol start winning opening 40 is closed. At this time, the start opening / closing door 41 (specifically, the outer surface 41G) is substantially flush with the front surface of the base portion 101. When the game ball passes through the normal symbol start gate 18 and the normal symbols 24A and 24B become, for example, odd numbers, “small hit game” is started, and the solenoid 43 provided on the rear side of the game board 11 is started. As a result, the start opening / closing door 41 falls to the front side for a predetermined period (for example, 0.4 seconds) (states of FIGS. 3, 6, and 8). As a result, the special symbol start winning opening 40 is opened forward, and the game ball can enter the special symbol start winning opening 40 by guiding the start opening / closing door 41 that has fallen forward. At this time, the start opening / closing door 41 is substantially perpendicular to the base portion 101.

  As shown in FIG. 5, the inner surface 41N of the start opening / closing door 41 is a flat surface. Side wall portions 49 are formed on both sides of the inner surface 41N. The side wall portion 49 is configured to rise from the inner surface 41N of the start port opening / closing door 41 and to become higher (away from the inner surface 41N) from the upper side 41J to the lower side 41K of the start port opening / closing door 41. The side wall portion 49 prevents the game ball received by the start opening / closing door 41 from falling to the side of the start opening / closing door 41.

  As shown in FIG. 7, a boss portion 46 is integrally formed on the side wall portion 49 on the rear side of the rotation shaft 42. The boss portion 46 protrudes toward the outside of the start port opening / closing door 41 (the front side in FIG. 7). Further, the upper edge portion 49J of the side wall portion 49 has a tapered shape so as to descend toward the inner surface 41N of the start port opening / closing door 41.

  A plurality of ribs 41R are formed on the outer surface 41G of the start opening / closing door 41 so as to connect the upper side 41J and the lower side 41K of the start opening / closing door 41 (see FIG. 5). Moreover, as shown in FIG. 3, the stopper part 48 is formed in the both sides of the outer surface 41G. The stopper portion 48 is provided with a stepped portion 48D standing in a stepped manner from the outer surface 41G of the starting port opening / closing door 41 near the lower side 41K of the starting port opening / closing door 41, and the upper side 41J of the starting port opening / closing door 41 from the stepped portion 48D. It inclines so that it may approach the outer surface 41G of the start opening / closing door 41 as it goes to (refer FIG. 5). When the angle of rotation of the start opening / closing door 41 to the front side reaches a predetermined angle, the stepped portion 48D of the stopper portion 48 contacts the surface of the accessory device 100 (specifically, the front surface of the base portion 101). In contact therewith, the start opening / closing door 41 does not fall forward any further. In this embodiment, when the start opening / closing door 41 is rotated about 75 ° from the state where the special symbol start winning opening 40 is closed (the state shown in FIGS. 5 and 7) to the front side, the step portion 48 </ b> D is formed on the base portion 101. It is comprised so that it may contact | abut to a front surface (state of FIG.6 and FIG.8). As a result, when the special symbol start winning opening 40 is opened, the inner surface 41N of the start opening / closing door 41 is inclined toward the special symbol start winning opening 40 at an angle of about 15 °. Therefore, the game balls received by the start opening / closing door 41 are smoothly guided to the special symbol start winning opening 40 by the inclination of the inner surface 41N of the start opening / closing door 41.

  When the start opening / closing door 41 is tilted about 75 ° to the front side, the upper side 41J of the start opening / closing door 41 is substantially flush with the front surface 103Z of the obstacle wall 103 (see FIG. 6). At this time, a gap between the upper side 41J of the start opening / closing door 41 and a glass plate (not shown) covering the front surface of the game board 11 is smaller than the diameter of the game ball. The game ball that has fallen down is prevented from falling downward from the front side (upper side 41J side) of the start opening / closing door 41. Also, as shown in FIG. 3, the start opening / closing door 41 that has fallen forward is sandwiched from the left and right by the obstacle walls 103, 103, so that the game ball dropped on the start opening / closing door 41 is It is also prevented from falling from the side of 41. Therefore, the game ball dropped on the start opening / closing door 41 surely enters the special symbol start winning opening 40.

  Here, as shown in FIGS. 7 and 8, the start opening / closing door 41 is connected to the solenoid 43 by a substantially L-shaped bent arm 44. Specifically, one end 44 </ b> A of the bending arm 44 is connected to the tip of a shaft 45 provided at the axial center portion of the solenoid 43, and the other end 44 </ b> B is a boss formed on the start port opening / closing door 41. 46. Further, the bent portion of the bent arm 44 is provided with a shaft portion 44J, and the bent arm 44 is rotatable about the shaft portion 44J.

  Specifically, when the solenoid 43 is excited and the shaft 45 moves directly to the solenoid 43 side (right side in FIG. 7), the bending arm 44 rotates about the shaft portion 44J in the clockwise direction in FIG. One end 44A of the bending arm 44 moves upward. Then, the start opening / closing door 41 rotates counterclockwise in FIG. 7 about the rotation shaft 42, and the start opening / closing door 41 is tilted forward with respect to the base portion 101 of the accessory device 100. The special symbol start winning opening 40 is opened by making it substantially perpendicular to the base portion 101 (the state shown in FIG. 8).

  On the other hand, when the solenoid 43 is demagnetized and the shaft 45 moves straight forward (left side in FIG. 8) so as to protrude from the solenoid 43 by the urging force of the compression coil spring 47, the bending arm 44 is centered on the shaft portion 44J. Is rotated counterclockwise, and one end 44A of the bending arm 44 moves downward. Then, the start opening / closing door 41 rotates about the rotation shaft 42 in the clockwise direction in FIG. 8 so that the start opening opening / closing door 41 is parallel to the base portion 101 and the outer surface 41G is substantially the same as the front surface of the base portion 101. Standing up so that it becomes a surface, the special symbol starting winning opening 40 is closed (the state of FIG. 7). The above is the description of the special symbol start winning opening 40 and the start opening / closing door 41.

  A large winning opening 50 corresponding to the “opening / closing ball opening” of the present invention is formed below the special symbol starting winning opening 40. Like the special symbol start winning opening 40, the big winning opening 50 has a horizontally long rectangular shape. The width of the big winning opening 50 is larger than the width of the lower end opening of the special symbol starting gate 17 and the special symbol starting winning opening 40. And as shown in FIG. 3, the special symbol starting gate 17 is arrange | positioned on the vertical line E which passes through the center part in the horizontal width direction (left-right direction of FIG. 3) of the special winning opening 50. As shown in FIG. The game ball that has flowed down the front surface of the game board 11 and entered the big prize opening 50 is guided to the back side of the game board 11. When a game ball enters the big winning opening 50, for example, 15 prize balls are paid out for each (one) entry. The prize ball corresponds to the “game prize” in the present invention, and the prize ball payout device (not shown) for paying out the prize ball corresponds to the “prize giving means” in the present invention.

  A ball receiving room 80 in which a game ball can roll is formed on the back side of the big prize opening 50. The ball receiving room 80 is slightly narrower than the special winning opening 50 and has a depth substantially equal to the diameter of the game ball.

  As shown in FIG. 3, stopper ridges 58 are formed on both side walls 86, 86 of the ball receiving room 80. The stopper protrusion 58 protrudes outwardly (in the left-right direction in FIG. 3) from the side wall portions 86, 86 and extends in the front-rear direction of the pachinko gaming machine 10. The stopper protrusion 58 limits the rotation angle of the special prize opening opening / closing door 51 described later.

  In the ball receiving room 80, a ball receiving port 82 through which a game ball can pass is formed through one side (the right end portion in FIG. 3) of the back wall 81 facing the special winning opening 50. The ball receiving port 82 has an arch shape that allows a single game ball to pass therethrough. Here, the bottom surface 80 </ b> S of the ball receiving room 80 is inclined so as to descend toward the ball receiving port 82. Specifically, the bottom surface 80S is lowered from the left end portion toward the right end portion, and the right end portion is lowered toward the back side. Thereby, the game balls transferred into the ball receiving room 80 from the special winning opening 50 are smoothly guided to the ball receiving port 82 (see FIG. 5). Ribs 88 and 88 are formed between the back wall 81 and both side walls 86 and 86 of the ball receiving room 80 (see FIG. 3). These ribs 88 and 88 project into the interior of the ball receiving room 80 and are inclined so as to approach the back wall 81 as the distance from the side wall 86 increases.

  The ball receiving port 82 communicates with a back side room 83 that extends further to the back side than the ball receiving room 80. The bottom surface 83S of the back side room 83 is flush with the right end portion of the bottom surface 80S of the ball receiving room 80, and is lowered toward the back side. Below the back room 83, a game ball sensor 85 (corresponding to "detecting means" of the present invention) is provided. The game ball sensor 85 includes a ball detection port 84 that penetrates in the vertical direction. The ball detection port 84 is a circular hole having a diameter larger than the diameter of the game ball. Further, a triangular projecting piece 87 projecting downward toward the back side is formed on the ceiling portion of the back side room 83. The game ball that has been vigorously transferred from the ball receiving room 80 to the back room 83 is brought into contact with the triangular protrusion 87 to change the rolling direction and fall from the ball detection port 84. The game ball that has passed through the ball detection port 84 is collected in a pachinko hall through a collection passage (not shown) provided on the back side of the game board 11.

  A game ball that has entered the big prize opening 50 is detected by the game ball sensor 85. That is, the game ball is not detected when it passes through the big prize opening 50, but when it passes through the big prize opening 50, passes through the ball receiving room 80, the back room 83, and the ball detection opening 84. Detected. As a result, there is a slight time difference between the game ball passing through the special winning opening 50 and being detected by the game ball sensor 85.

  The big prize opening 50 is provided with a big prize opening / closing door 51 corresponding to the “drive door” of the present invention. The big prize opening / closing door 51 has a horizontally long strip shape corresponding to the opening of the big prize opening 50, and a rotating shaft 52 with the lower side 51 </ b> K interposed between both sides of the big prize opening 50. It is pivotally supported by. Thereby, the special winning opening opening / closing door 51 is rotatable in a plane orthogonal to the surface of the game board 11.

  The special prize opening / closing door 51 is always in a closed state so that a game ball cannot enter the special prize opening 50 by standing in parallel (vertical direction) with the base portion 101 of the accessory device 100. (State of FIGS. 5 and 7). At this time, the winning opening opening / closing door 51 (specifically, the outer surface 51G) is substantially flush with the front surface of the base portion 101. When the game is in a big hit state (when the special symbols 13A, 13B, and 13C become a slotted pattern), the solenoid 53 (the “door drive means” of the present invention) in which the big prize opening / closing door 51 is provided on the rear side of the game board 11 is provided. To the front side of the base portion 101 over a predetermined period. As a result, the special winning opening 50 is opened (the state shown in FIGS. 3, 6 and 8), and the so-called “big hit” in which a game ball can enter the special winning opening 50 by guiding the special winning opening / closing door 51. "Game" is executed. Then, the condition that either the opening time of the big prize opening 50 has reached 29.5 seconds or the number of balls entered into the big prize opening 50 reaches a predetermined number (for example, nine) is the first condition. Is satisfied, the special prize opening opening / closing door 51 is driven to bring the special prize opening 50 into a closed state. In addition, if the period from the opening of the special winning opening 50 to the closing is referred to as “round”, the “big hit game” is performed up to 15 rounds.

  As shown in FIG. 5, a plurality of ribs 51 </ b> R are formed in parallel on the outer surface 51 </ b> G of the special prize opening / closing door 51 so as to connect the upper side 51 </ b> J and the lower side 51 </ b> K. On the other hand, the inner surface 51N of the prize winning opening / closing door 51 is a flat surface. Side wall portions 59 are provided on both sides of the inner surface 51N of the big prize opening opening / closing door 51. The side wall 59 stands up from the inner surface 51N of the prize winning opening / closing door 51 and has a tapered shape so as to become higher (away from the inner face 51N) from the upper side 51J to the lower side 51K. . The side wall portion 59 prevents the game ball that has fallen on the special prize opening opening / closing door 51 from dropping downward from both sides of the special prize opening opening / closing door 51. A stepped surface 89 (see FIG. 14) is formed on the inner surface 51N of the special prize opening opening / closing door 51 near the one side wall portion 59 so as to rise from the inner surface 51N. The step surface 89 is inclined so as to move away from the side wall 59 as it goes toward the lower side 51K.

  As shown in FIG. 7, a boss portion 56 is integrally formed at a portion of the side wall portion 59 that is behind the rotating shaft 52. The boss portion 56 protrudes from the side wall portion 59 toward the outside of the special prize opening opening / closing door 51 (the front side in FIG. 7). Further, the upper edge portion 59J of the side wall portion 59 has a tapered shape so as to descend toward the inside of the special prize opening opening / closing door 51.

  As shown in FIGS. 7 and 8, the special prize opening / closing door 51 is connected to a solenoid 53 by a bending arm 54. One end portion 54A of the bending arm 54 is connected to the tip end portion of the shaft 55 provided in the axial center portion of the solenoid 53, and the other end portion 54B is connected to the boss portion 56 provided in the prize winning opening / closing door 51. ing. Further, the bent portion of the bending arm 54 is provided with a shaft portion 54J, and the bending arm 54 is rotatable about the shaft portion 54J.

  For example, when the solenoid 53 is demagnetized and the shaft 55 moves linearly in the direction protruding from the solenoid 53 (upward in FIG. 8) by the urging force of the compression coil spring 57, the bending arm 54 is counteracted in FIG. By rotating clockwise, one end 54A of the bending arm 54 moves downward. Then, the special winning opening opening / closing door 51 rotates about the rotation shaft 52 in the clockwise direction in FIG. 8 so that the special winning opening opening / closing door 51 is parallel to the base portion 101 of the accessory device 100 and the outer surface 51G is the base. Standing so as to be substantially flush with the front surface of the portion 101, the special winning opening 50 is closed (the state shown in FIG. 7).

  Further, for example, when the solenoid 53 is excited and the shaft 55 moves directly to the solenoid 53 side (downward in FIG. 7), the bending arm 54 rotates about the shaft portion 54J in the clockwise direction in FIG. One end 54A of the arm 54 moves upward. Then, the prize winning opening / closing door 51 rotates about the rotation shaft 52 in the counterclockwise direction in FIG. 7, and the prize winning opening / closing door 51 is tilted forward from the base portion 101 of the accessory device 100. Then, the big winning opening 50 is opened by being substantially perpendicular to the base 101 (state shown in FIG. 8).

  By the way, the special winning opening opening / closing door 51 is restricted by the stopper protrusions 58, 58 formed on both side walls 86, 86 of the ball receiving room 80 so that it does not fall forward by a predetermined angle or more when the special winning opening 50 is opened. Has been. Specifically, when the big prize opening / closing door 51 is tilted to the front side of the game board 11 by, for example, about 75 °, the lower end portion of the side wall portion 59 of the big prize opening / closing door 51 is placed on the lower surfaces of the stopper protrusions 58 and 58. The award winning opening / closing door 51 cannot be rotated any more by the contact (the state shown in FIG. 3). At this time, the inner surface 51N of the special winning opening / closing door 51 is inclined so as to descend toward the game board 11 (large winning opening 50) at an angle of about 15 ° (see FIG. 6). Thereby, the game balls received by the special prize opening / closing door 51 are smoothly guided to the special prize opening 50 by the inclination of the inner surface 51N of the special prize opening / closing door 51. Note that when the prize winning opening / closing door 51 falls about 75 ° toward the front side of the game board 11, the upper side 51 </ b> J of the prize winning opening / closing door 51 and the front face 104 </ b> Z of the obstacle wall 104 are substantially flush with each other. And the clearance gap between the upper side 51J of the big prize opening opening-and-closing door 51 which fell to the front side of the game board 11, and the glass plate (not shown) which covers the front surface of the game board 11 becomes smaller than the diameter of a game ball. Therefore, it is possible to prevent the game ball that has fallen on the special winning opening opening / closing door 51 from dropping downward from the front side (upper side 51J side) of the special winning opening opening / closing door 51. Further, as shown in FIG. 3, since the big prize opening / closing door 51 that has fallen to the front side is sandwiched between the obstacle walls 104, 104, the game ball dropped on the big prize opening / closing door 51 becomes the big prize opening. It is also prevented from falling from the side of the opening / closing door 51. Therefore, the game ball that has dropped onto the special prize opening / closing door 51 surely enters the special prize opening 50.

  Now, the special winning opening open / close door 51 provided in the pachinko gaming machine 10 of the present embodiment is formed with a door passage path 90 through which a game ball can pass. As shown in FIG. 9, the door passageway 90 is a central portion in the horizontal width direction (left and right direction in FIG. 9) of the big prize opening / closing door 51, more specifically, when the big prize opening / closing door 51 falls to the front side. Is formed at a portion intersecting with the vertical line E passing through the special symbol starting gate 17, and is opened to the upper side 51J side of the special prize opening opening / closing door 51 and is depressed toward the lower side 51K. The lateral width of the portion 90J closer to the upper side 51J of the large winning opening / closing door 51 in the door passageway 90 is larger than the diameter of the game ball. Further, the portion 90K closer to the lower side 51K of the prize winning opening / closing door 51 is curved in an arc shape so as to be away from the upper side 51J of the prize winning opening / closing door 51 (to approach the lower side 51K of the prize winning opening / closing door 51). Yes. Further, the depth of the door passageway 90, that is, the length from the open end on the upper side 51J side of the prize winning opening / closing door 51 to the innermost part 90S of the door passageway 90 is larger than the diameter of the game ball. . As a result, when the big prize opening / closing door 51 falls to the front side (when the big prize opening 50 is in an open state), the game balls that have dropped vertically from the center vertically in the width direction of the big prize opening / closing door 51 are: Without being received by the special winning opening / closing door 51, it passes through the door passage 90 and falls below the special winning opening 50.

  Of the large winning opening 50, when the large winning opening / closing door 51 closes the large winning opening 50, the “passing prevention section for the door passing path” of the present invention is located at a position facing the door passing path 90. As a ball entry preventing projection 95 is formed. The ball entry preventing protrusion 95 hangs down from the center position in the width direction of the upper side 50J of the big prize opening 50 and extends to an intermediate position in the height direction (vertical direction in FIG. 9) of the big prize opening 50. When the special winning opening 50 is in a closed state, the ball entry preventing protrusion 95 is disposed inside the door passageway 90 of the special winning opening / closing door 51 (see FIG. 9). At this time, the gap formed between the peripheral edge of the door passage 90 and the ball entry protrusion 95 is smaller than the diameter of the game ball in any part. It becomes impossible to pass. This reliably prevents the game ball from entering the special winning opening 50 when the special winning opening 50 is closed.

  The above is the configuration of the pachinko gaming machine 10 according to the present embodiment. Next, the operation of the pachinko gaming machine 10 having the above configuration will be described. When the operation knob 28 is operated and the game balls are ejected to the upper part of the game area R1 of the game board 11, the game balls are directed to the obstacle nails, the windmill 19, the decorative frame 23, etc., and the direction is changed. Pass through the game area R1.

  When the game ball flowing down the game area R1 passes through the normal symbol start gate 18, the normal symbols 24A and 24B start to be displayed in the normal symbol display section 24 provided in the decorative frame 23. When the normal symbols 24A and 24B stop at an odd number of eyes after the predetermined time has elapsed, the “small hit game” is started, the start opening / closing door 41 falls to the front side, and the special symbol start winning port 40 is opened. Opened.

  In addition, when the game ball wins (passes or enters) the special symbol start gate 17 or the special symbol start winning opening 40, the special symbols 13A, 13B, and 13C start the variable display on the display 34. Then, when the special symbols 13A, 13B, and 13C stop, for example, in a glance after a predetermined time has elapsed, a “big hit game” is started, and a big hit effect display is performed on each display device 206A and 206B. The winning opening 50 is opened, and many game balls can be awarded to the big winning opening 50.

  Here, the flow path of the game ball flowing down on the accessory device 100 in the front surface of the game board 11 will be described. For example, when both the special symbol start winning opening 40 and the big winning opening 50 are closed, the following is performed. As shown in FIG. 10, the game ball that has passed through the special symbol start gate 17 falls vertically toward the special symbol start winning port 40 without changing the falling direction by the obstacle nail or the like. However, since the special symbol start winning opening 40 is in a closed state (the start opening / closing door 41 is in a standing state), the game ball passes through the central front side in the width direction of the special symbol start winning opening 40 (start opening / closing door 41) and is special. It falls below the symbol start winning opening 40.

  The game ball that has passed through the front face of the special symbol start winning opening 40 falls vertically toward the big winning opening 50 without changing the falling direction by an obstacle nail or the like. However, since the grand prize opening 50 is in a closed state (the grand prize opening opening / closing door 51 is in a standing state), the game ball passes through the center front side in the width direction of the big winning opening 50 (large winning opening opening / closing door 51), It falls below 50 and enters the out port 16 (see the arrow indicated by symbol a in FIG. 10).

  Similarly, the game ball that has flowed down without passing through the special symbol start gate 17 falls without entering the special symbol start winning port 40 and the big winning port 50 (arrow b in FIG. 10). See).

  Next, when only the special symbol start winning port 40 of the special symbol start winning port 40 and the big winning port 50 is in an open state, the following is performed. As shown in FIG. 11, the game ball that has passed through the special symbol start gate 17 falls vertically and falls onto the start opening / closing door 41 that has fallen to the front side of the game board 11. The game ball that has dropped onto the start opening / closing door 41 enters the special symbol start winning opening 40 by the inclination of the start opening / closing door 41 (see the arrow indicated by symbol a in FIG. 11). That is, when the special symbol start winning opening 40 is in the open state, the game ball that has passed through the special symbol start winning gate 17 enters the special symbol start winning opening 40 and therefore does not fall toward the big winning opening 50. Similarly, a game ball that has flowed from the diagonally upward toward the special symbol start winning opening 40 without passing through the special symbol starting gate 17 is received by the start opening / closing door 41 and enters the special symbol start winning opening 40. Sphere.

  A game ball that has flowed down toward the grand prize opening 50 without passing through the special symbol starting gate 17, for example, a game ball that has passed between the obstacle walls 103 and 104 from diagonally above the special prize opening 50 (reference symbol b in FIG. 11). ) Passes through the front side of the big winning opening / closing door 51 without entering the big winning opening 50 and enters the out opening 16.

  Next, when both the special symbol start winning opening 40 and the big winning opening 50 are in the open state, it is as follows. As shown in FIG. 12, the game ball that has passed through the special symbol start gate 17 falls vertically, is received by the start port opening / closing door 41 that has fallen to the front side of the game board 11, and enters the special symbol start winning port 40 ( (See arrow a in FIG. 12). That is, the game ball that has passed through the special symbol start gate 17 does not fall toward the big prize opening 50.

  A game ball that has flowed down toward the grand prize opening 50 without passing through the special symbol starting gate 17 (for example, a game ball that has passed between the obstacle walls 103 and 104) has fallen to the front side of the game board 11 Of the open / close door 51, it falls to a portion near both left and right end portions with the door passage path 90 interposed therebetween. The game balls received by the big prize opening / closing door 51 are guided by the inclination of the big prize opening / closing door 51 and enter the big prize opening 50 (see arrow b in FIG. 12). In other words, the game ball that has passed through the special symbol start gate 17 is received by the start opening / closing door 41, and therefore does not enter the grand prize opening 50, but does not pass through the special symbol start gate 17 (big prize) A game ball that has flowed down toward the grand prize opening 50 (from an obliquely upper side of the mouth 50) can enter the big prize opening 50.

  Now, when only the special winning opening 50 out of the special symbol starting winning opening 40 and the special winning opening 50 is in an open state, it is as follows. As shown in FIG. 13, a game ball that has flowed toward the grand prize opening 50 without passing through the special symbol starting gate 17 (for example, a game ball that has passed between the obstacle walls 103 and 104) is opened and closed. It falls to the left and right end portions of the door 51 and is guided by the special winning opening / closing door 51 to enter the special winning opening 50 (see the arrow b in FIG. 13).

  On the other hand, the game ball that has passed through the special symbol start gate 17 falls vertically toward the special symbol start winning opening 40. However, since the special symbol start winning opening 40 is in a closed state, the game ball passes through the front side of the special symbol start winning opening 40 without being received by the start opening / closing door 41 and falls as it is.

  The game ball that has passed through the special symbol start winning opening 40 falls vertically from the vertically upper center in the width direction of the big winning opening 50 toward the big winning opening opening / closing door 51 that falls to the front side of the game board 11. At this time, the door passage 90 formed in the special winning opening opening / closing door 51 opposes the upper and lower openings 17J and 17K of the special symbol start gate 17 on the vertical line E (see FIGS. 3 and 14). The game ball passes through the door passage 90 and falls below the special winning opening 50 (see the arrow indicated by symbol a in FIG. 13). That is, when the special winning opening 50 is in an open state, the game balls that have passed through the special symbol starting gate 17 are not received by the special winning opening opening / closing door 51, and the gaming balls that have passed through the special symbol starting gate 17 have received a big prize. A ball entering the mouth 50 is prevented.

  That is, when the special winning opening 50 is in an open state, the gaming balls that have not passed through the special symbol starting gate 17 can enter the large winning opening 50, while the gaming balls that have passed the special symbol starting gate 17 receive a big prize. Entering into the mouth 50 can be avoided.

  By the way, in a gaming machine in which a gate through which a game ball passes (for example, a special symbol start gate 17) is arranged at a position directly above the grand prize winning opening 50, and a gaming ball that has passed through the gate can enter the big winning prize opening 50. When the game ball easily passes through the gate by adjusting the obstacle nail or the like, the following problem occurs.

  That is, a large number of game balls may pass through the gate in succession as many game balls are guided to the gate by the obstacle nail. Then, a large number of game balls fall toward the big prize opening 50 at once, and, for example, a plurality of game balls fall on the big prize opening opening / closing door 51 at substantially the same timing. Here, as described above, there is a slight time difference between the game ball entering the grand prize opening 50 and being detected by the game ball sensor 85. For example, the big prize opening 50 is closed. When a predetermined number (nine) of game balls, which is one of the conditions, is detected by the game ball sensor 85, another game ball has already moved into the big prize opening / closing door 51 or the ball receiving room 80. State can occur. In this case, a larger number of game balls enter a predetermined number (9) during one round.

  If, in each round (15 rounds) of “Big Bonus Game”, one extra ball is entered than the predetermined number, the game store pays out 225 (15 × 15 rounds) prize balls excessively. In other words, if one prize ball is cashed for 2.5 yen, the game store will pay an extra “562 yen” for each “big hit game”. Further, assuming that the number of “big hit games” executed per day by the pachinko gaming machine is 20, the game shop will pay an extra “11240 yen” per pachinko gaming machine. Furthermore, if the above-mentioned phenomenon occurs in 500 pachinko machines provided in the game store, the game store pays an extra “5.62 million yen” per day, which is a great damage.

  However, according to the pachinko gaming machine 10 of the present embodiment, the game ball that has dropped vertically after passing through the special symbol start gate 17 passes through the door passage 90 formed in the big prize opening / closing door 51. There is no entry into the winning opening 50. Thereby, it is possible to eliminate the game balls that pass through the special symbol starting gate 17 and enter the grand prize opening 50, and the game balls can be prevented from entering the big prize opening 50 as compared with the conventional gaming machine. .

  Even if the game ball is easy to pass through the special symbol start gate 17 by adjusting the obstacle nails or the like, the game ball that has passed through the special symbol start gate 17 is prevented from entering the big prize opening 50. Is prevented from being overpaid. Therefore, it is easy to pass the special symbol start gate 17 to improve the game's taste, and it is possible to prevent damage to the game store.

[Second Embodiment]
In the second embodiment, the shape of the special prize opening and the special prize opening / closing door are different from those of the first embodiment. Since other configurations are the same as those in the first embodiment, the same reference numerals are given to the same configurations, and duplicate descriptions are omitted.

  As shown in FIG. 16A, in the pachinko gaming machine according to the present embodiment, the upper side of the big prize opening 50 is located at the center of the big prize opening 50 in the width direction (left and right direction in FIG. 16A). And a lower plate 200 are provided. The partition plate 200 has a vertically long rectangular shape, and the lateral width is substantially the same as the diameter of the game ball. Further, the front surface of the partition plate 200 is flush with the front surface of the base portion 101. With this partition plate 200, the special winning opening 50 is divided into two, a left opening 50L and a right opening 50R, with a vertical line E passing through the special symbol start gate 17 interposed therebetween. Both the left side opening 50L and the right side opening 50R are rectangular. In addition, the big winning opening 50 is divided into a left opening 50L and a right opening 50R, but the back side portion (inside the ball receiving room 80) is connected to the big winning opening 50.

  The big prize opening / closing door 151 for opening and closing the big prize opening 50 is as follows. As shown in FIG. 15, a rectangular notch 152 having a lateral width larger than the diameter of the game ball is formed in the central portion in the width direction (left-right direction in FIG. 15) of the special prize opening opening / closing door 151 (FIG. 16). (See (B)). The rectangular notch 152 opens to the upper side 151J side of the special prize opening opening / closing door 151 and extends to the vicinity of the lower side 151K. A left side component 151L having substantially the same shape as the left opening 50L of the big winning opening 50 is provided on the left side of the rectangular notch 152, and a right side having substantially the same shape as the right opening 50R is provided on the right side of the rectangular notch 152. A component 151R is provided. The left side component 151L and the right side component 151R are connected by the lower side 151K of the prize winning opening / closing door 151.

  The big prize opening / closing door 151 is pivotally supported by the rotation shaft 52 at the lower side 150K. The left component 151L and the right component 151R of the prize winning opening / closing door 151 rotate together in a plane orthogonal to the surface of the game board 11. That is, the left opening 50L and the right opening 50R of the special winning opening 50 are simultaneously opened or closed.

  When only the special winning opening 50 out of the special symbol starting winning opening 40 and the special winning opening 50 is opened, the game ball flows down the front side of the accessory device 100 as follows.

  As shown in FIG. 16A, a game ball that has flowed toward the grand prize opening 150 without passing through the special symbol starting gate 17 (for example, between the obstacle walls 103 and 104 from obliquely above the big prize opening 50). Some of the game balls that have passed through are received by the left component 151L or the right component 151R of the big prize opening / closing door 151 and enter the big prize mouth 150 (in FIG. 16A). (See arrow b).

  On the other hand, the game ball that has passed through the special symbol start gate 17 passes through the front side of the special symbol start winning opening 40 without being received by the start opening / closing door 41, and falls vertically.

  The game ball that has passed through the special symbol start winning opening 40 falls vertically from the vertically upper center in the width direction of the big winning opening 50 toward the big winning opening / closing door 151. However, a rectangular portion having a lateral width larger than the diameter of the game ball is formed between the central portion in the width direction of the special prize opening / closing door 151, that is, between the left component 151L and the right component 151R of the special prize opening / closing door 51. Since the notch 152 is formed, the game ball passes through the inside of the rectangular notch 152 and falls below the special winning opening 50 (refer to the arrow a in FIG. 16A). Accordingly, the game ball that has passed through the special symbol starting gate 17 is received by the big prize opening / closing door 151 (specifically, the left component 151L or the right component 151R), and the big prize outlet 50 (specifically, the left opening 50L). Or, the ball does not enter the right opening 50R).

  Further, a portion of the special winning opening 150 that overlaps with the falling path of the game ball that has dropped vertically from the special symbol starting gate 17, that is, a central portion in the width direction of the special winning opening 150 is covered with the partition plate 200. Thereby, it is possible to prevent a game ball that has dropped vertically from the special symbol start gate 17 from directly entering the big winning opening 150 (without being guided to the big winning opening / closing door 151). In addition, when the special winning opening 50 is closed, the portion corresponding to the rectangular notch 152 of the special winning opening / closing door 151 is closed by the partition plate 200, so that the special winning opening 50 is closed. In addition, the game ball is prevented from passing through the rectangular cutout 152 and entering the big winning opening 50. The partition plate 200 and the rectangular cutout 152 constitute a “central passage” of the present invention. Thus, even with the configuration of the present embodiment, the same effects as those of the first embodiment can be obtained.

[Third Embodiment]
The pachinko gaming machine 10 of this embodiment is provided with a blocking plate 301 that moves in and out in the front-rear direction of the game board 11. The special winning opening / closing door 351 has a rectangular strip shape that is substantially the same shape as the special winning opening 50. That is, similarly to the start opening / closing door 41, the large winning opening / closing door 351 is configured to cover the entire large winning opening 50 in the closed state. Other configurations are the same as those in the first embodiment.

  As shown in FIG. 17, in the base portion 101 of the accessory device 100, a flat horizontally long slit 300 is formed through an intermediate portion between the special symbol start gate 17 and the special symbol start winning opening 40. Specifically, the slit 300 is spaced apart from the lower end opening 17K of the special symbol start gate 17 by one game ball (for example, about 11 mm) or more vertically above the center of the base portion 101 in the width direction of the special winning opening 50. It is formed in a vacant position. The slit 300 has substantially the same width as the special symbol start winning opening 40. A blocking plate 301 is inserted into the slit 300 from the back side of the game board 11.

  The blocking plate 301 has substantially the same lateral width as the special symbol start winning opening 40, and the upper surface 301J is inclined so as to be lowered from the center in the width direction to the side. The blocking plate 301 is connected to, for example, a blocking plate solenoid (not shown) on the back side of the game board 11. Then, when the special winning opening opening / closing door 51 falls to the front side and the special winning opening 50 is opened, the solenoid for the blocking plate is excited, and the blocking plate 301 protrudes forward of the game board 11 through the slit 300. (The state shown in FIG. 17B). In addition, when the special winning opening opening / closing door 51 is in an upright state and the special winning opening 50 is closed, the shielding plate solenoid is demagnetized and the shielding plate 301 is retracted to the rear of the game board 11. When the shielding plate 301 is retracted to the rear of the game board 11, the front end portion of the shielding plate 301 is located behind the front surface of the base portion 101 (left side in FIG. 17B). The “blocking drive unit” of the present invention is constituted by the blocking plate 301 and the blocking plate solenoid.

  Now, when only the special winning opening 50 is opened among the special symbol starting winning opening 40 and the special winning opening 50, the game ball flows down the front side of the accessory device 100 as follows.

  As shown in FIG. 17, a game ball that has flowed down toward the grand prize opening 50 without passing through the special symbol starting gate 17 (for example, a game that has passed between the obstacle walls 103 and 104 from diagonally above the big prize opening 50. Some of the spheres) fall into the grand prize opening / closing door 351 and enter the big prize opening 50 (see the arrow b in FIG. 17).

  On the other hand, the game ball that has dropped vertically through the special symbol starting gate 17 falls to the central portion of the upper surface 301J of the blocking plate 301. And it rolls to the side by the inclination of the upper surface 300J of the shielding board 301, and falls from the side edge part of the shielding board 301. FIG. Most of the game balls that have dropped from the blocking plate 301 flow down outside the obstacle walls 130 and 104 (see the arrow indicated by symbol a in FIG. 17). This makes it possible to reduce the number of game balls that pass through the special symbol start gate 17 and enter the big winning opening 50, as compared to a pachinko game machine in which the blocking plate 301 is not provided. As described above, according to the present embodiment, it is possible to achieve the same effects as those of the first and second embodiments.

  When the special winning opening 50 is in the closed state, the blocking plate 301 is retracted to the rear of the base portion 101 of the accessory device 100, so that the game ball that has passed through the special symbol starting gate 17 contacts the blocking plate 301. Without falling, the front side of the big prize opening 50 falls vertically. In this way, the flow path of the game ball that has passed through the special symbol start gate 17 can be made different between when the special winning opening 50 is in the open state and when it is in the closed state.

[Fourth Embodiment]
In the present embodiment, the shape of the grand prize opening / closing door is different from that of the first embodiment. Only the configuration different from that of the first embodiment will be described below. As shown in FIG. 18, a drop prevention protrusion 400 is formed on the special prize opening opening / closing door 451 of the present embodiment. The fall prevention protrusion 400 is provided along the peripheral edge portion of the door passage 90, and stands upright from the inner surface 51N of the special prize opening opening / closing door 451. As a result, the game ball that has dropped onto the special winning opening / closing door 451 is prevented from falling from the door passageway 90.

[Fifth Embodiment]
In the fifth embodiment, the configuration of the “door entrance prevention portion for the door passage way” is different from that of the first embodiment. Only the configuration different from that of the first embodiment will be described below.
As shown in FIG. 19, a rectangular band plate-shaped saddle member 500 is provided at the center portion in the width direction of the special prize opening opening / closing door 51. More specifically, the eaves member 500 stands perpendicularly from the outer surface 51G of the big prize opening / closing door 51 and is arranged so as to straddle the open part on the upper side 51J side of the big prize opening / closing door 51 in the door passageway 90. Yes. When the special winning opening 50 is in a closed state (when the special winning opening / closing door 51 is in a standing state), the collar member 500 covers the upper side of the door passage 90 and the front surface of the base portion 101 of the accessory device 100. Protrude from.

  For example, a game ball that has dropped vertically from the special symbol starting gate 17 when the winning openings 40 and 50 are both closed is in contact with the saddle member 500 and passes through the door without passing through the front of the door passage 90. It flows down the side of the road 90. Thereby, when the special winning opening 50 is in a closed state, the gaming balls are prevented from entering the special winning opening 50 through the door passageway 90. In addition, the game ball dropped toward the center portion in the lateral width direction of the big prize opening / closing door 51 (large prize opening 50) is not limited to the game ball dropped vertically from the special symbol start gate 17, and contacts the saddle member 500. As a result, the flow direction changes, and it becomes impossible to enter the big winning opening 50 from the door passage 90.
