JP 2006-136501 A

However, as shown in FIG. 10 of Patent Document 1, for example, the conventional warp device of a gaming machine has a minimum required size that allows only one gaming ball to pass through the inner diameter of the ball flow downway or the ball outlet. Therefore, the guidance mode of the game ball guided to the stage part by the warp device (the position and direction of the game ball when guided to the stage part) is almost constant each time, and the transition in the stage part Was almost constant and boring. Note that the minimum necessary size through which only one game ball can pass is specifically about 12 mm in diameter for a pachinko game ball having a diameter of 11 mm, for example.
Accordingly, an object of the present invention is to provide a gaming machine that can change the rolling mode of the game ball in the stage unit by changing the guiding mode of the game ball by the warp device.

A gaming machine according to claim 1 of the present application is disposed in a gaming area formed on a gaming board, and is disposed in a concave chamber-shaped center case having an open front surface, and an inner bottom portion of the center case. A stage part that can flow down to the game area below the center case and a ball inlet opening toward the game area outside the center case. In a gaming machine comprising: a warp device that opens a ball outlet at a lower end of a ball flow downstream communicating with an inlet to a required portion in the concave chamber and guides a game ball flowing into the ball inlet to the stage unit ,
Among the warp devices, the inner diameter of the ball flow downway and the ball outlet is configured to be larger than the necessary minimum size through which only one game ball can pass,
A game ball that flows down through the ball flow outlet and flows out from the ball outlet by forming a mounting boss for screwing the warp device to the center case so as to protrude into the ball flow down path The position and the direction of movement of the lens are randomly changed by the mounting boss.

  In addition, as a preferable aspect of the present invention, for example, as described in claim 2, by forming a plurality of the mounting bosses so as to be staggered along the extending direction of the spherical flow downstream, the spherical downstream is formed. May be a meandering flow path.

For example, as described in claim 3, the stage portion has a depth width wider than the diameter of the game ball,
The inner diameters of the spherical flow outlet and the spherical outlet are configured to be larger than the necessary minimum size at least in the depth direction of the stage portion,
The plurality of mounting bosses may be formed on the front and rear wall portions of the ball flow down path.

  In addition, for example, as described in claim 4, a game ball that has flowed out of the ball outflow port in contact with the game ball that has flowed out of the ball outflow port at a position corresponding to the ball outflow port in the stage portion You may form the random distribution part which changes the rolling direction of this at random.

Further, for example, as described in claim 5, the stage portion is configured to incline downward from an end portion in the left-right direction toward the center,
The ball outlet is opened above one of the left and right sides of the stage part,
The random distribution part may be configured by a plurality of ridges that are inclined downward toward the left and right other side parts of the stage part and have different inclination angles.

  Further, for example, as described in claim 6, in the gaming machine according to claim 1, in contact with the game ball that has flowed out of the ball outlet at a position corresponding to the ball outlet in the stage portion. A random distribution unit that randomly changes the rolling direction of the game ball that has flowed out of the ball outlet may be formed.

  According to the gaming machine of claim 1, the flow direction of the game ball passing through the warp device is that the inner diameter of the ball flow path and the ball outlet of the warp device is larger than the minimum required size. It is possible to change the (trajectory of the flow), and the game sphere is guided to the stage portion by the game sphere bouncing back irregularly by the mounting boss protruding into the ball flow down path. (At least the position and direction of movement of the game ball when guided to the stage unit) randomly change (that is, change irregularly every time). For this reason, the rolling mode of the game ball that rolls on the stage unit is also random, and it is possible to give an irregular change to the effect due to the movement of the game ball in the stage unit. Therefore, the player who is watching the game ball guided to the stage part by the warp device does not get bored. In addition, since the mounting boss for screwing the warp device to the center case is also used as a means for irregularly rebounding the game ball in the ball flow downway, it is necessary to form a separate protrusion or the like as this means. There is also an advantage that there is no.

Further, according to the gaming machine of the second aspect, by forming a plurality of mounting bosses so as to be staggered along the extending direction of the ball flow down path, the ball flow down path becomes a meandering flow path. Therefore, the speed of the game ball guided by the warp device can be effectively reduced, and the stage portion is not damaged by the momentum of the guided ball.
In addition, according to the gaming machine of the third aspect, since the game ball guided by the warp device is randomly guided with respect to the depth direction of the stage unit, the game ball flows down from the stage unit to the lower game area. It is possible to change the rolling time of the game ball.

In addition, according to the gaming machine according to claim 4 or claim 6, in addition to the randomness given to the game ball by the warp device, further randomness can be given by the random sorting unit. The rolling mode of the game ball becomes more varied, and the interest in the rolling mode of the game ball can be enhanced.
Further, according to the gaming machine according to claim 5, since the random distribution unit is configured by a plurality of ridges inclined downward toward the left and right other sides of the stage unit and having different inclination angles, Depending on which ridge the game ball that has flowed out from the outlet hits, the speed at which the stage rolls changes, the rolling manner of the game ball becomes more varied, and once the game ball is changed After that, it will not interfere with the rolling of the game ball.

Further, the inner diameter L2 of the ball flow lower path 22 and the ball flow outlet 23 is a minimum necessary size that allows one game ball to pass at least in the depth direction of the stage unit 50 (in this case, the front-rear direction of the pachinko machine). It is set larger than 12 mm with respect to 11 mm of game balls. Specifically, the inner diameter L2 is set to approximately 20 mm, for example.

The mounting base member 68 has mounting holes 79 and 80 (through holes in the left-right direction) formed at positions corresponding to the mounting bosses 77 and 78, respectively. The ball flow path forming member 72 is fixed to the mounting base member 68 by inserting mounting screws (not shown) through the mounting holes 79 and 80 and screwing them into the screw holes 77a and 77b of the mounting bosses 77 and 78, respectively ( It is screwed).
Further, the ball inflow port forming member 71 and the ball flow lower path forming member 72 are transparent or semi-transparent so that a game ball flowing in the ball flow lower path 22 can be seen by the player.

D. Outline of Game Next, an outline of a game performed in the pachinko machine of the present embodiment and a flow of the game will be described.
First, at the beginning of the game (or before the start of the game), the customer is in a waiting state (during demonstration), and the customer waiting image (video or still image) is displayed on the screen (display unit 6) of the display device 5. ) Is displayed.
When a game ball that has been thrown into the game area 3 via the guide rail 2 wins the start winning opening 11 (that is, when there is a start winning of the special figure), the display unit 6 displays the fluctuation of the special figure. Then, the variable display game is executed.

  And, apparently, the special display stop display mode (a combination of special maps derived by the variable display) on the display unit 6 of the variable display game is a special display mode (for example, “3, 3, 3”, etc.) ), A bonus called jackpot is given to the player. In terms of control, for example, on the condition that there has been a start winning, the value of the big hit random number is extracted and stored, and the random number value that has been extracted and stored is compared and determined at the time of determination. Based on the determination result, whether or not to make a big hit is determined in advance, and the variable display game is started in response to this determination.

  When the big hit state is reached, an opening operation is performed in which the big winning opening 13 is temporarily opened for a period up to, for example, ten winnings within a range not exceeding a prescribed time (for example, 30 seconds). This release operation is performed up to 15 rounds, for example. In this jackpot state, display of the jackpot image for producing the jackpot state or notifying the player of the number of jackpot rounds is executed on the display unit 6.

Further, when a game ball is further won in the start winning opening 11 during the above-described variation display game or big hit, for example, the display unit 6 performs a special diagram start memory display and stores up to four to display the variation display. After the game or jackpot is over, the variable display game of the special figure is repeated or returned to the customer waiting state based on the memory (that is, the start memory).
That is, if the variable display game ends with a big hit, the game shifts to a big hit state, and if the variable display game ends with a start and there is a start memory, the variable display game is executed again, and the variable display game ends with a start and no start memory is stored. If the jackpot ends and the start memory is stored, the variable display game is executed again. If the jackpot ends and there is no start memory, the flow returns to the customer waiting state.

On the other hand, when the game ball passes through the usual figure start gate 15 during the game, a usual figure change display game is performed by the usual figure change display on the ordinary figure display. And if this variable display game result (stopped common figure) is a predetermined aspect, the privilege called per figure will be provided.
At this time, a game is held in which the pair of opening and closing members 11a of the start winning opening 11 is held in an open state in which the shape of the opening is reversed, for example, for about 0.5 seconds. As a result, there is a possibility that a game ball will enter the start winning opening 11 and it becomes easy to start winning, and accordingly, the number of executions of the special display variable display game is increased and the possibility of being a big hit increases.
Also, during the above-described variable display game, when a game ball is further won in the general chart start gate 15, a general chart start display is executed on the general chart storage display, and in this case, up to four are stored. After the end of the variable display game shown in the figure, the usual variable display game is repeated based on the memory.

According to the gaming machine of the present example described above, the inner diameters of the ball flow down path 22 and the ball outlet 23 of the warp device 20 are larger than the minimum necessary size through which only one game ball can pass. This makes it possible to change the flow of the game ball passing through the warp device 20 (the trajectory of the flow, the position and the direction of flow), and the ball flow down path 22 by the mounting bosses 77 and 78 protruding into the ball flow down path 22. The game balls guided to the stage unit 50 randomly change at random (the position and the direction of movement of the game balls when guided to the stage unit 50) by the internal game balls bouncing irregularly ( That is, it changes irregularly every time).
For example, the position of the game ball flowing out from the ball outlet 23 to the warp ball rolling path 51 is on the back side as shown in FIG. 6A or on the near side shown in FIG. 6B. . Further, the direction of movement of the game ball flowing out from the ball outlet 23 to the warp ball rolling path 51 is inclined or tilted toward the back side or the near side with respect to the extending direction (lateral direction) of the warp ball rolling path 51. Or the tilt angle is large or small.
For this reason, the rolling mode of the game ball that rolls on the stage unit 50 is also random, and it is possible to give an irregular change to the effect due to the movement of the game ball in the stage unit 50. Therefore, the player who is watching the game ball guided to the stage unit 50 by the warp device 20 does not get tired.

In addition, since the mounting bosses 77 and 78 for screwing the warp device 20 to the center case 10 are also used as means for irregularly rebounding the game ball in the ball flow downway 22, a separate protrusion is provided as this means. There is also an advantage that it is not necessary to form.
In addition, according to the gaming machine of this example, a plurality of mounting bosses 77 and 78 are formed so as to be staggered along the extending direction of the ball flow down path 22 so that the ball flow down path 22 becomes a meandering flow path. Therefore, the speed of the game ball guided by the warp device 20 can be effectively reduced, and the stage unit 50 is not damaged by the momentum of the guided ball.
In addition, since the game ball guided by the warp device 20 is randomly guided in the depth direction of the stage unit 50, a change in the rolling time of the game ball until it flows down from the stage unit 50 to the lower game area. Can be given.

(Second embodiment)
Next, a second embodiment will be described with reference to FIG.
In the following, only the features of the second embodiment (the differences from the first embodiment) will be described. Other configurations are the same as those of the first embodiment. FIG. 7 is a perspective view illustrating the random distribution unit 90 of the second embodiment.
In this example, a game that has flowed out of the ball outlet 23 at a position corresponding to the ball outlet 23 of the warp device 20 in the stage unit 50 (that is, the inclined surface 51a at the left end of the warp ball rolling path 51 in this case). A random distribution unit 90 is formed, which abuts on the ball and changes the rolling direction of the game ball flowing out from the ball outlet 23 at random. The random distribution unit 90 includes a plurality of ridges 91 to 97 that are inclined downward toward the other left and right side portions (in this case, the right end side) of the stage unit 50 and have different inclination angles. In this case, the protrusions 91 to 97 have a triangular pyramid shape that tapers toward the downstream side (right end side).

According to the gaming machine of this example, in addition to the randomness given to the game balls by the warp device 20, further randomness can be given by the random distribution unit 90, so the rolling mode of the game balls at the stage unit 50 Can be more varied, and can enhance the interest in the rolling mode of the game ball.
Moreover, since the random distribution part 90 is comprised by the some protruding item | line 91-97 which inclines down toward the right-and-left other side part of the stage part 50, and the inclination angle differs, the game which flowed out from the ball | bowl outflow port 23 Depending on which ridges 91 to 97 the ball hits, the speed at which the stage 50 rolls changes, and the rolling mode of the game ball becomes more varied, and once the game ball has changed Does not disturb the rolling of the game ball.

The present invention is not limited to the above-described embodiments, and various modifications and applications are possible.
For example, in the above-described embodiment, a configuration in which the inner diameter of the ball flow downstream 22 or the like is further increased (for example, a configuration in which two game balls can pass through the inner diameter of the ball flow downstream 22 at the same time) may be used.

  In addition, it should be considered that the embodiment disclosed this time is illustrative and not restrictive in all respects. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
