Then, the protrusions 46 are arranged in a state of extending in the front-rear direction, and the interval between the protrusions 46 is set to a width that allows the game balls to pass through, for example, a width that allows the bottom end of the game balls to be sufficiently fitted. A guide path 47 extending in the front-rear direction is formed between the protrusions 46. Furthermore, the downstream end (front end or end located on the opening side of the concave chamber 17) of the protrusion 46 is opposed to the upstream side (rear side or case large winning opening 33 side) of the front auxiliary guiding portion 44 described later. In addition, the auxiliary guiding portion 44 is disposed on the extension lines on the left and right side edges. Therefore, the guide path 47 has a downstream end connected to the upstream side of the auxiliary guide portion 44. The protrusion 46 is inclined downward from the center portion in the left-right direction toward the side edge portion, and the game ball rolling from the side of the guide portion 43 rolls on the inclined surface and gets over the protrusion 46 and is guided. It is configured to be able to enter the part 43, that is, the guide path 47, and to guide the game ball to the front auxiliary guide part 44.

  When the door member 36 is maintained in the closed state, the guide portion 43 arranged on the door member 36 as described above is upstream of the guide path 47 (projection 46) as shown in FIG. The side end is disposed at a position slightly lower than the front stage 28, so that the game ball rolling on the front stage 28 and the rear stage 27 can be received in the guide path 47. Then, the received game ball can be guided above the start winning opening 8. In other words, when the door member 36 is converted into the closed state, the guide unit 43 converts the game ball into a guide state in which the game ball can be guided above the start winning opening 8.

  On the other hand, when the door member 36 is converted to the open state, as shown in FIG. 4B, the guide portion 43 is disposed vertically along the door member 36, and the upstream end of the guide path 47 and the door The free end of the member 36 is set at a position higher than the front stage 28. As a result, the game ball that rolls the front stage 28 and the rear stage 27 without being able to roll the game ball on the door member 36 and reach the guide path 47 of the guide portion 43. Cannot be received by the guide path 47. In other words, when the door member 36 is converted to the open state, the guide unit 43 converts the game ball into a non-guideable state in which the game ball is not guided above the start winning opening 8.

  The auxiliary guiding portion 44 is a passage disposed between the guiding portion 43 and the start winning opening 8 in the ball rolling portion 24 (front stage 28), specifically in front of the guiding portion 43. And the downstream end of the auxiliary guide portion 44 is opened right above the start winning opening 8. The auxiliary guide portion 44 of the present embodiment is configured by a recess formed by recessing the front edge of the front stage 28 downward, and the upper end (the front stage 28 side end) of the recess is directed to the guide portion 43. The front side (the glass plate 5 side) is opened toward the start winning opening 8 (specifically, directly above the starting winning opening 8).

Next, the operation of the ball rolling unit 24 will be described. It is assumed that the door member 36 of the case large winning opening 33 has been converted to the closed state in advance, and the guiding portion 43 has been converted to the guiding state.
In a pachinko gaming machine having the gaming board 1 configured as described above, when a gaming ball is launched from a launching device (not shown), the gaming ball is guided by the guide rail 2 and reaches the upper part of the gaming area 4. After that, when the player moves down the game area 4 while changing the direction by the obstacle nail or the windmill and wins the normal start gate 9, the general winning opening 12, and the starting winning opening 8, a predetermined prize ball is given to the player. If no prize is won, the game is collected from the out port 13 to the back side of the game board 1. Then, when the game ball wins the general figure starting gate 9, the pachinko machine performs a general figure change display game (auxiliary game) in the general figure change display section (not shown), and the result of the normal figure change display game is obtained. When the mode is “winning”, the opening / closing member 8a of the start winning opening 8 is opened, and the game ball is converted into a state where it is easy to win the start winning opening 8. If the game ball passes through the normal diagram start gate 9 during the execution of the normal variation display game, the normal variation display game that should be executed by the passage of this game ball is performed a predetermined number of times (for example, a maximum of four times). ) And hold in an unprocessed (unexecuted) state. Further, the number of game balls that have been suspended is displayed on, for example, a part of the display unit 7a of the display device 7 or a general variable storage display unit (not shown) provided separately on the game board 1, and the previous time After the map change display game is completed, the pending map change display game is sequentially executed.

  Further, when the game ball flows down the side (left side) of the center case 6 and enters the ball lead-out path 25, the game ball passes from the exit of the ball lead-out path 25 to the rear stage 27 of the ball rolling unit 24. The rear stage 27 rolls toward the central portion in the left-right direction due to the downward flow. When the game ball reaches the front guide portion 31 or the recess of the central portion of the rear stage 27 in a state where the momentum of the game ball swinging left and right on the rear stage 27 is weakened, the game ball is Then, while moving left or right, it rolls forward and flows down to the front stage 28. Then, the game ball that has flowed down from the rear stage 27 rolls the front stage 28 toward the central portion in the left-right direction, and reaches the upper surface of the door member 36 of the case large winning opening 33. On the other hand, the game ball that has flowed down from the recess in the central portion of the rear stage 27 falls directly to the rear side of the upper surface of the door member 36. When the game ball reaches the door member 36, the game ball rolls forward on the door member 36 without reaching the guide portion 43 due to the downward flow of the game ball, or enters the guide path 47 of the guide portion 43. Or Then, the game ball that rolls forward in a place off the guiding portion 43 falls to a position outside the start winning opening 8 in the game area 4. Further, the game ball that has reached the guiding part 43 in the guiding state flows down the guiding path 47 of the guiding part 43 and falls to the auxiliary guiding part 44 as shown in FIG. It falls directly above the winning opening 8. Therefore, the game ball guided to the guiding part 43 and the auxiliary guiding part 44 is likely to win the start winning opening 8.

  Furthermore, the game ball that has flowed down the side of the center case 6 without entering the ball lead-out path 25 is bounced off by the obstacle nail below the center case 6 and flies, enters from the front of the concave chamber 17 and rolls. In some cases, the moving stage 24 may reach the front stage 28. In this case, the game ball that has reached the front stage 28 flows down toward the door member 36 due to its flight force, and does not reach the guide portion 43 (or passes through the guide portion 43). Rolling forward, or entering the guide path 47 of the guide portion 43. Then, the game ball that rolls away from the guide unit 43 falls to a position in the game area 4 that is off from just above the start winning opening 8. Further, as shown in FIG. 4A, the game ball that has reached the guide unit 43 flows down the guide path 47 of the guide unit 43 and falls to the auxiliary guide unit 44. Fall directly above. Therefore, the game ball guided to the guiding part 43 and the auxiliary guiding part 44 is likely to win the start winning opening 8.

  When the game ball wins the start winning opening 8, a special figure variation display game is played on the display unit 7 a of the display device 7. As a result of this special figure variation display game, when the display content on the display unit 7a becomes a predetermined special display (bonus display), the pachinko gaming machine generates a special gaming state (bonus state) advantageous to the player, Divide into multiple rounds and execute special games. At this time, in a certain round, only the area big prize opening 11 is opened so that a game ball can be won, and in a specific round (corresponding to the specific game state in the present invention) where the area big prize opening 11 is not opened, Only the big winning opening 33 is opened, that is, the door member 36 is converted to an open state so that a game ball can be won. Therefore, the guiding unit 43 converts to a non-guideable state. If the game ball wins the start winning opening 8 during the execution of the special figure fluctuation display game, the special figure fluctuation display game that should be executed by the winning is stored up to a predetermined number of times (for example, a maximum of four times). , Hold in an unprocessed (unexecuted) state. Further, the number of winning prizes held is displayed on, for example, a part of the display unit 7 a of the display device 7 or a variable display storage display unit (not shown) provided separately on the game board 1.

  Further, when the game ball passes through the ball lead-out path 25 or is bounced by the obstacle nail below the center case 6 and reaches the ball rolling part 24 with the door member 36 converted to the open state, this game As shown in FIG. 4 (b), the ball wins the case big prize opening 33 or rolls forward from the side of the case big prize opening 33 in the front stage 28 and flows down to the game area 4. Or At this time, since the door member 36 is converted to an open state and the guide portion 43 is further converted to a non-guideable state, the game ball rolling on the ball rolling portion 24 reaches the guide portion 43 of the door member 36. Can not do it. As a result, it is not possible to flow down directly above the auxiliary guiding portion 44 and thus the start winning opening 8.

  Thus, the center case 6 allows the game ball to enter the case big prize opening 33 by opening the door member 36 in a specific round (specific game state) in the special game state, It is prevented from being guided to the start winning award 8 side through the guiding portion 43 and the auxiliary guiding portion 44. On the other hand, in a non-specific game state in which a specific game state has not occurred (specifically, a game state in which a special game state other than a specific round in the special game state or a special game state that is a jackpot state has not occurred) The door member 36 is closed to prevent the game ball from winning the case large winning opening 33, and the game ball is allowed to be guided to the start winning opening 8 side through the guiding portion 43 and the auxiliary guiding portion 44. To do. Therefore, by opening and closing the door member 36, it is possible to change whether or not the game ball rolling on the ball rolling part 24 can win the case big winning opening 33, and further, the game on the ball rolling part 24 By complicating the behavior of the sphere, the degree to which the game ball is guided to the start winning opening 8 below the center case 6, specifically, whether or not it is guided to the start winning opening 8 can be changed. From this, it is possible to change the expectation that the game ball will win the start winning opening 8 by opening and closing the door member 36 of the case large winning opening 33, and it is possible to enhance the interest of the game.

  In addition, the auxiliary guiding portion 44 is configured by a hollow portion having an upper end opened toward the guiding portion 43 side and a lower end opened toward the start winning port 8 side. The game ball flowing down from the guiding portion 43 can be easily won in the start winning opening 8. From this, even if the distance between the start winning opening 8 and the guiding portion 43 (specifically, the case large winning opening 33) is vertically separated, the game ball is difficult to be guided from the guiding portion 43 to the starting winning opening 8. Can be avoided. As a result, the degree of freedom of the layout of the components of the game board 1 can be increased, and it becomes easy to realize a pachinko gaming machine with enhanced game interest. Further, the guide portion 43 is composed of two protrusions 46 protruding from the upper surface of the door member 36, and the downstream end of the protrusion 46 is disposed at a position facing the upstream side of the auxiliary guide portion 44. It is possible to realize the guiding portion 43 capable of guiding the above with a simple configuration.

  When the predetermined number of rounds is completed in the special game state, the pachinko gaming machine returns from the special game state to the normal game state, and closes the area big prize port 11 and the case big prize port 33. If an unexecuted special figure fluctuation display game is put on hold, the special figure fluctuation display game is executed again.

  In addition, the guide part 43 provided in the door member 36 is not limited to being formed by the two protrusions 46. For example, the guide part 43 ′ of the modification shown in FIG. 5 is configured by a recess formed by recessing the upper surface of the door member 36 (the upper surface of the door member 36 in the closed state) downward. Further, the recess is opened upward and forward to form a guide path 47 ′ that can guide the game ball forward inside the recess, and the guide path 47 ′ is arranged behind the auxiliary guide section 44. Specifically, the downstream side of the guiding path 47 ′ (that is, the depression) is arranged in a state of facing the upstream side of the auxiliary guiding part 44, and the guiding path 47 ′ and the auxiliary guiding part 44 are communicated with each other. Providing the guide portion 43 ′ constituted by such a recess can stably guide the game ball and make it easier to win the game ball on the door member 36 to the start winning opening 8. it can.

  By the way, in the said embodiment, when the door member 36 was converted into the open state, it comprised so that the game ball on the ball rolling part 24 might not be guide | induced to the start winning opening 8, However, This invention is not limited to this. For example, the case large winning opening 50 according to the second embodiment shown in FIG. 6 has basically the same configuration as that of the first embodiment, but does not include the guiding portion and the auxiliary guiding portion, and instead, the door member 36. The difference is that an inductive flow lower portion 52 capable of guiding the game ball on the door member 36 to the start winning opening 8 side is provided regardless of opening and closing. More specifically, the guide flow lower part 52 includes a guide inlet 53 formed in the door member 36, a guide flow path 54 disposed in the spherical flow lower space part 37, and a front partition wall of the spherical flow lower space part 37. And an induction outlet 55 opened at the same time.

  The induction inflow port 53 is formed by a circular through-hole through which a game ball can pass, and to the rear stage 27 at a position corresponding to the substantially center of the door member 36 in the left-right direction, in other words, directly above the start winning opening 8. It is opened in the state where it came. In addition, the guide channel 54 is configured by inclining a saddle member whose upper and front sides are opened downward and inclined forward. When the door member 36 is converted to a closed state, the guide channel 54 is covered from above by the door member 36, and the guide channel An induction inflow port 53 is communicated with an upstream portion (rear portion) of 54. On the other hand, when the door member 36 is converted to the open state, the door member 36 is configured to be disengaged from the upper side of the guide flow path 54 so that the game ball can be received from above without passing through the guide inflow port 53. . The induction outlet 55 is formed in the front partition wall of the ball lowering space portion 37, in other words, on the front side of the bottom portion 22 of the concave chamber 17 by penetrating a circular through-hole through which a game ball can pass in the front-rear direction. It is arranged immediately above the start winning opening 8. In addition, the downstream end of the guide channel 54 communicates with the rear of the guide outlet 55.

  When such a guide flow lower part 52 is provided and the pachinko gaming machine generates a specific round (specific game state) during the special game state, the door member 36 is in the open state (vertical line indicated by a two-dot chain line in FIG. 6B). The winning opening 35 is opened, and the guide channel 54 is exposed at a substantially central portion of the winning opening 35 in the left-right direction. In this state, when the game ball on the ball rolling unit 24 reaches the case large winning opening 50 and flows down from the left and right outer sides of the guide channel 54 to the winning opening 35, the game ball is separated from the ball flow down space 37 and Pass the winning detection sensor 38. In this way, the game ball wins the case big prize opening 50. When the game ball flows down to the guide channel 54, the game ball flows down through the guide channel 54, passes through the guide outlet 55, and is guided directly above the start winning opening 8. Therefore, the game ball that has flowed down the guide channel 54 is likely to win the start winning opening 8.

  On the other hand, in a state other than the specific round occurrence state (non-specific game state), the door member 36 is converted into a closed state (a horizontal state shown by a solid line in FIG. 6), and the winning opening 35 is closed, and the induction inflow port is formed. 53 and the guide channel 54 communicate with each other. In this state, when the game ball on the ball rolling unit 24 reaches the upper surface of the door member 36 of the case large winning opening 50 and rolls forward without falling to the induction inlet 53, the game ball is started. It is easy to flow down to the game area 4 from a position deviated from right above the mouth 8 to the left and right, so that it is easy to win the start winning opening 8. When the ball falls to the guide inlet 53, the game ball flows down through the guide channel 54, passes through the guide outlet 55, and is guided directly above the start winning opening 8. Therefore, the game ball that has flowed down the guide channel 54 is likely to win the start winning opening 8.

  Thus, the center case 6 in the second embodiment allows the game ball to win the case big prize opening 50 by opening the door member 36 in a specific round (specific game state) in the special game state. At the same time, the upper part of the guide channel 54 is opened to allow the game ball that has fallen to the guide channel 54 to be guided to the start winning port 8 side through the guide channel 54 and the guide outlet 55. On the other hand, in the non-specific game state in which the specific game state has not occurred, the door member 36 is closed to prevent the game ball from winning the case large winning opening 50, and the game ball is guided to the induction inlet 53, the induced flow. It is permitted to win the start winning opening 8 through the path 54 and the induction outlet 55. Therefore, by opening and closing the door member 36, it is possible to change whether or not the game ball rolling on the ball rolling part 24 can win the case big winning opening 50, and further, the game on the ball rolling part 24 By complicating the behavior of the ball, it is possible to change the degree to which the game ball is guided to the start winning opening 8 below the center case 6, specifically, the route guided to the start winning opening 8. From this, by opening and closing the door member 36 of the case large winning opening 50, it is possible to change the expectation that the game ball will win the winning portion different from the case large winning opening 50, that is, the starting winning opening 8. The fun of gaming can be enhanced.

  In addition, it is possible to set so that the game ball can win the start winning opening 8 while the specific game state is generated. As a result, the execution of the special figure variation display game based on the winning can be suspended, and the reserved special figure variation display game can be executed immediately after returning from the special game state to the normal game state. Therefore, the player can enjoy a plurality of special figure variation display games in a short period of time, and can further enhance the interest of the game.

  By the way, in each above-mentioned embodiment, although one door member 36 was provided in case special winning opening 33,50, the present invention is not limited to this and may provide a plurality of door members. For example, the case large winning opening 60 of the center case 6 in the third embodiment shown in FIG. 7 has the same basic configuration as the above embodiments, but includes two door members 61, The difference is that a ball passage 62 through which a game ball can pass is provided.

  More specifically, in the case large winning opening 60 in the third embodiment, a ball passage 62 that is inclined downward and forward is disposed in the center portion of the winning opening 35 in the left-right direction. It is set wider than the diameter of the sphere. Further, the lower end of the slope, which is the downstream portion of the ball passage 62, is arranged at a position corresponding to the position directly above the start winning prize opening 8. In addition, two door members 61 that can open and close the left and right sides of the winning opening 35 are disposed on both the left and right sides of the ball passage 62, and the rotation shaft 63 of each door member 61 is directed in the inclination direction of the ball passage 62. The pivot shaft 63 is pivotally attached to the ball passages 62 on both front and rear side edges of the prize opening 35 so that the pivot shaft 63 can pivot freely, and the end of the pivot shaft 63 is opened and closed. Connected to solenoid output rod. For example, in a normal state in which the open / close solenoid is demagnetized, the door member 61 has its free end (outer end) disposed in the vicinity of the side edge of the winning opening 35 and slightly tilted downward. The posture is set, and the closed state (sideways state) in which the winning opening 35, that is, the case large winning opening 60 is closed is maintained (see FIG. 7A). On the other hand, when the open / close solenoid is energized, it rotates around the rotation shaft 63, moves the free end of the door member 61 upward, and opens the winning opening 35, that is, the case large winning opening 60 ( (Vertical orientation) (see FIG. 7B). The door member 61 in the closed state is disposed at a position slightly lower than the front stage 28 located on the left and right, and the game ball that has flowed down the front stage 28 or the rear stage 27 rolls to the upper surface of the door member 61. It is set to be able to move. In addition, on both the left and right sides of the inclined lower end portion of the ball passage 62, in front of the door member 61 and the winning opening 35, a guide protrusion 64 capable of guiding the game ball forward is provided as a rotation axis of the door member 61. It protrudes in a state along the extension line 63.

  When such a ball passage 62 and the door member 61 are provided and the pachinko gaming machine generates a specific round (specific game state) during the special game state, the left and right door members 61 are converted to the open state and the winning opening 35 Is opened (see FIG. 7B). Further, the left and right door members 61 are arranged in a standing posture in the vicinity of the side edge of the ball passage 62. In this state, when the game ball on the ball rolling portion 24 approaches from the side of the winning opening 35 other than the rear of the ball passage 62 of the case big winning opening 60, for example, the gaming ball flows down to the winning opening 35. Therefore, it is easy to win the case big prize opening 60. Further, when the game ball approaches from behind the ball passage 62 of the case large winning opening 60, the game ball easily enters the ball passage 62. Further, it is guided to the downstream side of the ball passage 62 by the standing door member 61 and guided directly above the start winning opening 8. Therefore, the game ball that has flowed down the ball passage 62 is likely to win the start winning opening 8.

  On the other hand, in a state other than the specific round occurrence state (non-specific game state), the left and right door members 61 are converted to the closed state, and the winning opening 35 is closed (see FIG. 7A). Further, the left and right door members 61 are arranged on substantially the same plane as the ball passage 62. In this state, when the game ball on the ball rolling unit 24 reaches the upper surface of the door member 61 of the case big prize opening 60, the game ball rolls forward on the door member 61 and the ball passage 62 to start the winning prize opening. Flow down above 8. At this time, since a member capable of restricting the flow direction of the game ball is not arranged between the ball passage 62 and the door member 61, even if the game ball rolls on the ball passage 62, May come off to the side, and as a result, it may flow down to a position off from directly above the start winning opening 8 and may not be guided to the starting winning opening 8. Therefore, when the door member 61 is in the closed state, the probability of guiding the game ball to the start winning opening 8 is likely to be lower than when the door member 61 is in the open state. When the game ball flows down to the inclined lower end portion of the ball passage 62, the game ball is unlikely to be detached from the ball passage 62 by the left and right guide protrusions 64. As a result, the game ball flows down directly above the start winning opening 8. Thus, it is easy to win the start winning opening 8.

  Thus, in the center case 6 in the third embodiment, in a specific round (special game state) in the special game state, the left and right door members 61 are opened and the game ball wins the case big prize opening 60. While permitting, the left and right door members 61 are arranged in a standing posture on the side edge of the ball passage 62, and the game balls passing through the ball passage 62 are guided above the start winning opening 8. On the other hand, in the non-specific game state in which the specific game state has not occurred, the left and right door members 61 are closed to prevent the game balls from winning the case large winning opening 60 and the left and right door members 61 are passed through the ball path. The game balls that are arranged on the same plane as 62 and pass through the ball passage 62 are allowed to be removed from the ball passage 62. Therefore, by opening and closing the door member 61, it is possible to change whether or not the game ball rolling on the ball rolling part 24 can win the case large winning opening 60, and further, the game on the ball rolling part 24 By complicating the behavior of the sphere, it is possible to change the degree to which the game ball is guided to the start winning opening 8 below the center case 6, more specifically, whether or not the game ball is easily guided to the starting winning opening 8. From this, it is possible to change the sense of expectation that the game ball will win the start winning opening 8 by opening and closing the door member 61 of the case large winning opening 60, and it is possible to enhance the interest of the game.

  Furthermore, it can be set so that the game ball can win the start winning opening 8 while the specific game state is generated. As a result, the execution of the special figure variation display game based on the winning can be suspended, and the reserved special figure variation display game can be executed immediately after returning from the special game state to the normal game state. Therefore, the player can enjoy a plurality of special figure variation display games in a short period of time, and can further enhance the interest of the game.

In addition, as shown in FIG. 8, the auxiliary | assistant guidance | induction part 66 is depressed in the ball rolling part 24 (front stage 28) between the ball channel | path 62 and the start winning opening 8, specifically, the front of the ball channel | path 62 below. , The upper end of the auxiliary guiding portion 66 is opened toward the ball passage 62 side, the lower end is opened toward the start winning port 8 side, and the game ball flowing down the ball passage 62 is moved to the auxiliary guiding portion 66. May be configured to guide to the start winning opening 8 side. If such an auxiliary guiding portion 66 is provided, it is possible to make it easier to win the game ball guided by the standing door member 61 to the start winning opening 8, and to further enhance the interest of the game.
Moreover, the door member in 3rd Embodiment is not limited to two. There may be three or more door members that can guide the game ball to the start winning opening 8 side in the open state.

  By the way, in each said embodiment, the ball flow down space part 37 is arrange | positioned under the door members 36 and 61, and a game ball flows down from the winning opening part 35, and wins to the case big winning opening 33, 50, 60. However, the present invention is not limited to this. For example, in the fourth embodiment shown in FIG. 9, the basic configuration is the same as that of the first embodiment, but the arrangement of the ball flow down space and the configuration around the door member are different. More specifically, in the case large winning opening 70 in the fourth embodiment, a ball guide path 72 capable of guiding a game ball backward is disposed below the door member 36. Further, it is located behind the door member 36 and the ball guide path 72, specifically, in the step wall 73 hanging between the front stage 28 and the rear stage 27, behind the door member 36 and the ball guide path 72. A passage opening 74 through which a game ball can pass rearward is opened at a location, and the opening height of the passage opening 74 is set slightly wider than the diameter of the game ball. Further, the upper edge portion of the passage opening 74 is disposed at a position higher than the closed door member 36 (or the front stage 28), and the lower edge portion is closed with the door member 36 (or the front stage 28) and the ball guide path. 72 is disposed at a position lower than the inclined lower end. A ball flow down space 75 is disposed behind the passage opening 74, and a winning detection sensor 38 is provided at the lower end of the ball flow down space 75.

  In the fourth embodiment, when a rib-shaped blocking protrusion 77 is provided on the free end side edge (rear edge) of the upper surface of the door member 36 and the door member 36 is converted to a closed state, the blocking protrusion 77 is arranged in front of the passage opening 74 and is configured to prevent the game ball from entering the passage opening 74. Further, the guide portion 43 is composed of two protrusions 46 protruding from the upper surface of the door member 36 and a guide path 47 formed between the protrusions 46, and the downstream end (front end) of the protrusion 46 is a start prize. The guiding portion 43 that is arranged near the mouth 8 and can guide the game ball can be realized with a simple configuration. Further, a guide protrusion 78 capable of guiding the game ball forward is provided in a line on the extension line of the protrusion 46 between the guide portion 43 and the start winning port 8 in the ball rolling portion 24. .

  With such a ball guide path 72, a passage opening 74 and a ball flow down space 75, when the pachinko gaming machine generates a specific round (specific game state) during the special game state, the door member 36 is in an open state (FIG. 9). (B) (vertical state indicated by a solid line), the winning opening 35 is opened, and the ball guide path 72 is exposed. Further, the free end portion of the door member 36 is moved away from the passage opening 74, and the upstream end of the guide path 47 and the free end portion of the door member 36 are set at a position higher than the front stage 28. As a result, the game ball that rolls the front stage 28 and the rear stage 27 without being able to roll the game ball on the door member 36 and reach the guide path 47 of the guide portion 43. Cannot be received by the guide path 47. In other words, when the door member 36 is converted to the open state, the guide unit 43 converts the game ball into a non-guideable state in which the game ball is not guided above the start winning opening 8. Further, in this state, when the game ball on the ball rolling unit 24 approaches the case large winning opening 70 and flows down to the winning opening 35, the game ball flows down the ball guide path 72 and rolls backward. It passes through the ball flow lower space portion 75, the ball flow lower space portion 75, and the winning detection sensor 38 and wins the case large winning opening 70.

  On the other hand, in a state other than the specific round occurrence state (non-specific game state), the door member 36 is converted into a closed state (a horizontal direction indicated by a two-dot chain line in FIG. 9B) and the winning opening 35 is closed. Then, the ball guide path 72 is covered by the door member 36 from above. Further, the free end portion of the door member 36 approaches the passage opening 74 and is disposed in front of a substantially intermediate portion in the vertical direction of the passage opening 74, and the vertical width of the portion of the passage opening 74 exposed above the door member 36. Is set to be narrower than the diameter of the game ball so that the game ball does not pass through the passage opening 74. Further, the guiding unit 43 converts to the guiding state. When the game ball reaches the door member 36 in this state, the game ball rolls forward on the door member 36 without reaching the guide portion 43 due to the downward flow of the game ball, or to the guide path 47 of the guide portion 43. Or enter. Then, the game ball that rolls away from the guide unit 43 falls to a position in the game area 4 that is off from just above the start winning opening 8. The game ball that has reached the guiding portion 43 in the guiding state flows down the guiding path 47 of the guiding portion 43 and reaches the guiding projection 78, and further falls directly above the start winning opening 8. Therefore, the game ball guided to the guiding portion 43 and the guiding protrusion 78 is likely to win the start winning opening 8.

  Thus, the center case 6 in the fourth embodiment opens the door member 36 to expose the ball guide path 72 and opens through the door member 36 in a specific round (special game state) of the special game state. The game ball is allowed to win the case big prize opening 70 away from 74, and the guiding portion 43 is converted into a non-inducible state to prevent the game ball from being guided to the start prize opening 8 side. On the other hand, in a non-specific game state in which a specific game state has not occurred, the door member 36 is closed to cover the ball guide path 72, and the door member 36 is brought close to the passage opening 74, so that the game ball is placed in the case big prize opening 70. And the guiding unit 43 is converted to a guiding state to allow the game ball to be guided to the start winning port 8 side. Therefore, by opening and closing the door member 36, it is possible to change whether or not the game ball rolling on the ball rolling part 24 can win the case large winning opening 70, and further, the game on the ball rolling part 24 By complicating the behavior of the sphere, the degree to which the game ball is guided to the start winning opening 8 below the center case 6, specifically, whether or not it is guided to the start winning opening 8 can be changed. From this, it is possible to change the expectation that the game ball will win the start winning opening 8 by opening and closing the door member 36 of the case large winning opening 70, and it is possible to enhance the interest of the game.

  Further, since the ball lowering space portion 75 is arranged behind the door member 36, the winning ball to the case large winning opening 70 can be guided and collected behind the door member 36. Therefore, it is not necessary to arrange the game ball collection path below the center case 6, and the degree of freedom in designing the center case 6 and the distance between the center case 6 and the starting winning opening 8 below the center case 6 are increased. be able to.

  10A, the blocking wall 80 extends upward from the free end of the door member 36 in the closed state, and the upper side of the passage opening 74 is sufficiently covered by the blocking wall 80. May be. When such a blocking wall 80 is provided and the door member 36 is converted to the open state, the blocking wall 80 is disposed in a state of protruding right above the start winning opening 8. Therefore, as shown in FIG. 10B, it is assumed that the game ball that has flowed down from the side of the center case 6 toward the start winning opening 8 is bounced by the life nail 14 and is prevented from winning the starting winning opening 8. Alternatively, the game ball can collide with the lower surface of the blocking wall 80 and bounce off, and can flow down toward the start winning port 8 again. As a result, the player can see the complicated movement of the game ball above the start winning opening 8 and can have a sense of expectation that this game ball may win the start winning opening 8. Thereby, the interest of the game can be improved.

  In each of the above-described embodiments, the start winning port 8 is arranged as a winning portion below the center case 6, but the present invention is not limited to this. Any winning portion may be used as long as the game ball can be won, for example, a general winning port for taking a game ball and winning, or a winning gate for passing a game ball and winning. Good.

  In addition, the auxiliary guiding unit is not limited to the depression, and may have any configuration as long as the game ball guided from the guiding unit can be guided to the winning portion. For example, you may form an auxiliary | assistant guidance part with a collar member.

  In the above-described embodiment, the pachinko gaming machine 1 which is a typical gaming machine has been described as an example. However, the present invention is not limited to this, and a center having a ball rolling portion capable of rolling a gaming ball. Any gaming machine may be used as long as the gaming machine is provided with a case and a winning portion that is arranged below the center case and can win game balls.
