Description

  The present invention relates to a variable prize device for a gaming machine and a gaming machine including the same.

  Some ball game machines are provided with variable winning means (15) for constituting a large winning opening means called an attacker (see, for example, Patent Document 1).

JP 2010-234136 A

  The variable winning means (15) of Patent Document 1 includes a horizontally-long rectangular winning case (20) corresponding to the variable winning opening (40), and the bottom of the case body (46) constituting the winning case (20). On the upper surface of the wall (50g), there is formed an inclined guide passage (54) for guiding the game ball won in the variable winning opening (40) to one end in the left-right direction. At the downstream end, a discharge guide passage (55) for guiding the game ball from the inclined guide passage (54) to the discharge port (33) protrudes rearward through the back wall (34). . The discharge guide passage (55) communicates with the discharge port (33) on the back side of the winning detection switch (35).

  And as shown in (FIG. 9), the inclined guide passage (54) is inclined so that the right side is lowered in order to guide the game ball to the right side in the left-right direction. As shown, it is formed in a form that does not incline in the front-rear direction. However, when installing a gaming machine on an amusement island, the installation angle in the front-rear direction is usually set so that the gaming machine tilts backward slightly (nekase). 54) is inclined so that the rear side becomes lower by the installation angle.

  Accordingly, when the game ball that has won the variable winning opening (40) flows down the inclined guide passage (54), it is guided to the rear side due to the inclination in the front-rear direction and flows down to the right side while contacting the back wall (34). Then, it is guided to the discharge guide passage (55). The game balls guided to the discharge guide passage (55) are guided toward the rear discharge port (33). At this time, a plurality of game balls enter the variable winning port (40) and simultaneously When flowing down the inclined guide passage (54), the plurality of game balls flow down side by side along the back wall (34), and the previous game ball changes direction toward the rear in the discharge guide passage (55). When trying to do so, it will be affected by the ball pressure of the next sphere. Thereby, the ball flow of the game ball flowing down the discharge guide passage (55) is obstructed, and the detection of the winning detection switch (35) may be delayed. Further, in the vicinity of the discharge guide passage (55) of the inclined guide passage (54), the guidance guide is directed in the same direction (backward) as the game ball guided by the discharge guide passage (55), so that the rear wall (34 ) May cause clogging of balls.

  An object of the present invention has been made in view of the above circumstances, and it is possible to improve the flow of game balls in a ball flow path connecting a winning opening and a discharge opening, prevent clogging of balls, and efficiently discharge game balls. It is an object of the present invention to provide a gaming machine variable winning device that can be discharged to an exit and a gaming machine using the same.

In order to solve the above problems, the variable prize winning device for gaming machines of the present invention is:
A winning opening for introducing game balls from the game area formed on the surface of the game board, a discharge opening for discharging the game balls introduced from the winning opening at the rear of the game board, and from the winning opening to the discharge opening. In a variable winning device for a gaming machine that has a ball path that follows and is fixed to a gaming board,
Parallel to the game board and arranged so as to be rotatable around a rotation axis extending in the left-right direction, and standing along the game board closes the winning opening and makes it difficult or impossible to introduce the game ball into the ball channel And a winning door that is displaced to an open position that opens the winning opening by facilitating from the closed position to the front side to facilitate or enable the introduction of the game ball into the ball flow path,
An electrical drive source that is linked directly to the winning door or indirectly through another member and displaces the winning door between a closed position and an open position;
The ball channel is formed at the rear end of the upstream channel corresponding to the winning port, and downstream from the inlet port through which the game balls can be passed one by one. Side flow path,
The upstream flow path is formed with a first rolling surface that is lowered toward the rear side in order to roll guide the game ball to the introduction port in the front area of the introduction port. The adjacent side region is formed with a second rolling surface that is lower in the left-right direction as it goes to the first rolling surface and lower in the front-rear direction as it goes to the front side. .

In order to solve the above problems, the gaming machine of the present invention is:
The game machine variable winning device is fixed to a game board.

  According to the variable prize device for gaming machine of the present invention and the gaming machine equipped with the same, the ball channel that continues from the prize opening to the discharge port corresponds to the prize opening and the upstream channel that extends rearward. It includes a downstream channel that is formed at the rear end of the upstream channel and that connects the inlet to the outlet through which game balls can be passed one by one. In the upstream flow path, a first rolling surface is formed in the front region of the introduction port so as to become lower toward the rear side in order to roll and guide the game ball to the introduction port. In the lateral region adjacent to the moving surface, a second rolling surface is formed which becomes lower as it goes to the first rolling surface in the left-right direction and lower as it goes to the front side in the front-rear direction.

  According to this, the second rolling surface is formed so as to be lower as it goes to the first rolling surface side in the left-right direction and to the front side in the front-rear direction, so that the game ball on the second rolling surface. Are guided along the rear end of the upstream flow path, the game balls will no longer flow down, and when the previous game ball tries to change direction backward on the first rolling surface, The influence of the ball pressure of the next sphere can be suppressed or avoided. In other words, the game ball guided from the second rolling surface to the first rolling surface is guided to the front side and introduced into the first rolling surface in a dispersed manner, and thus flows down the first rolling surface. It is possible to reduce the influence of the ball pressure on the playing ball. As a result, the flow of the game balls in the ball flow path becomes good, the ball can be prevented from being clogged, the game balls can be efficiently discharged to the discharge port, and the winning of the game balls can be detected quickly. In addition, since the second rolling surface is formed so as to become lower as it goes forward, the movement of the ball is changed with respect to the game ball that has been won from the winning opening and introduced from the front. The occurrence of clogging can be effectively prevented.

  Further, the second rolling surface of the upstream flow path can be configured such that the inclination angle in the front-rear direction is larger than the inclination angle in the left-right direction.

  According to this, since the inclination angle in the front-rear direction is larger than in the left-right direction, the game ball on the second rolling surface is largely guided and guided forward, and the first rolling surface is The direction of the game ball about to flow down can be set in the direction opposite to the flow direction. When the game ball on the second rolling surface comes into contact with the game ball on the first rolling surface, the direction to flow down is the opposite direction, and the game ball on the first rolling surface remains as it is. It becomes possible to flow down toward the inlet. That is, since the game ball on the second rolling surface does not flow down so as to interrupt the game ball on the first rolling surface, the occurrence of the ball clogging can be effectively suppressed and prevented.

Further, in the variable prize device for gaming machines, the introduction ports are provided at least at two places with a predetermined interval in the left-right direction at the rear end of the upstream flow path,
A first rolling surface is formed in a front region of each of the adjacent inlets, and both sides of the side region sandwiched by the first rolling surface are set to have a predetermined intermediate position in the left-right direction. It can be set as the structure in which the 2nd rolling surface which became low as it went to the 1st rolling surface side was formed, respectively.

  According to this, since the introduction port and the first rolling surface are provided in two places, and the second rolling surface is formed in the side region between them, a plurality of game balls can win from the winning port at the same time. In addition, the second rolling surface can be guided and distributed to the two first rolling surfaces and the introduction port. As a result, the distance for guidance and guidance is shortened by the second rolling surface, the time from winning to discharging can be shortened, and the winning of the game ball can be detected quickly.

The upper case 30A and the lower case 30B are formed with guide portions 39a and 39b for standing (hanging down) at both ends of the stage portion 37 and guiding and guiding the game ball toward the center.

  Here, the ball flow path 13 is formed at the rear end of the upstream flow path 14 corresponding to the winning opening 11 and the rear end of the upstream flow path 14, and can be passed through the game balls one by one. 15 and a downstream flow path 16 connected to the discharge port 12. That is, in the upstream flow path 14, the stage portion 37 constitutes the bottom wall, and the guide portions 39 a and 39 b constitute the side walls. An opening between the guide portions 39 a and 39 b and the back wall 38 constitutes the introduction port 15.

  As shown in FIGS. 6 to 8, the stage portion 37 (upstream channel 14) goes to the rear side in order to roll and guide the game ball to the introduction port 15 in the front region of the introduction port 15. The lower first rolling surface 37a is formed (see FIG. 6), and the lateral region adjacent to the first rolling surface 37a is lower in the left-right direction as it goes to the first rolling surface 37a ( In the front-rear direction, a second rolling surface 37b is formed that becomes lower in the front-rear direction (see FIG. 8).

  In addition, the introduction ports 15 are provided at at least two places at predetermined intervals in the left-right direction at the rear end of the upstream flow path 14, and the first rolling is performed in the front region of each of the adjacent introduction ports 15. Surfaces 37a and 37a are formed, and both first rolling surfaces 37a and 37a are formed in a lateral region sandwiched between the first rolling surfaces 37a and 37a so that a predetermined intermediate position is a top T in the left-right direction. The second rolling surfaces 37b and 37b are formed so as to become lower toward the side.

  Further, the second rolling surface 37b is set so that the inclination angle in the front-rear direction is larger than the inclination angle in the left-right direction. Specifically, as shown in FIG. 7 (b), the relative inclination angle in the left-right direction of the second rolling surface 37b with respect to the virtual straight line X extending in the left-right direction in front view is defined as an angle α, and FIG. ), When the relative inclination angle in the front-rear direction of the second rolling surface 37b is defined as the angle β with reference to the virtual straight line Z extending in the front-rear direction in the side view, the angle β is larger than the angle α. Is set to As a result, when a game ball flows down on the second rolling surface 37b, the game ball is guided and guided more in the front-rear direction than in the left-right direction.

  In addition, although the 2nd rolling surface 37b of this embodiment is formed including a flat surface, it is not limited to this, You may be formed including a curved surface. Even in such a case, a configuration in which the game ball on the second rolling surface 37b is guided and guided in the front-rear direction larger than the left-right direction is preferable.

  Next, with reference to FIGS. 9 and 10, a flow pattern in which a game ball won from the winning opening 11 is guided and guided to the introduction opening 15 in the upstream flow path 14 (stage portion 37) will be described. An arrow (a chain line) extending in the radial direction from the ball center indicates a direction in which the game ball is about to flow down.

  In FIG. 9, two game balls A1 and A2 flow down in the upstream flow path 14, the game ball A1 is positioned on the first rolling surface 37a while being in contact with the guide portion 39b, and the game ball A2 is It is located on the second rolling surface 37b while being in contact with the game ball A1 and the back wall 38. Accordingly, the game ball A1 tends to flow toward the rear inlet 15 as indicated by the arrow, and the game ball A2 attempts to flow downward as indicated by the arrow. As a result, the direction in which the game balls A1 and A2 flow down is the opposite direction, so that the game ball can be guided and guided to the introduction port 15 without causing a ball clogging. Further, as shown in FIG. 7, the boundary between the first rolling surface 37a and the second rolling surface 37b is formed in a step shape, and the game balls A1 and A2 that are in contact with each other are separated (ball collapse). Can be further improved, and the occurrence of clogging of balls can be effectively prevented.

  In FIG. 10, three game balls B1, B2, B3 flow down in the upstream flow path 14, and the game ball B1 is positioned on the first rolling surface 37a while being in contact with the guide portion 39b. B2 is in contact with the game ball B1 and is positioned on the second rolling surface 37b and the winning door 40, and the game ball B3 is in contact with the game ball B1 and the guiding portion 39b and on the first rolling surface 37b and the winning door 40 Is located. Accordingly, the game ball B1 tries to flow down toward the rear introduction port 15 as indicated by the arrow, and the game ball B2 tries to flow down toward the front as indicated by the arrow. Since the first rolling surface 37a is formed so as to extend in the front area of the guide portion 39b, the game ball B3 follows the game ball B1 and faces the rear introduction port 15 as indicated by the arrow. Try to flow down.

  That is, the game ball B2 is once guided and guided forward by the second rolling surface 37b (when the momentum is small, the side surface is formed by the groove formed by the second rolling surface 37b and the winning door 40). (Guided and guided to the first rolling surface 37a side), the game ball B3 in addition to the game ball B1 is guided to the introduction port 15 in preference to the game ball B2. As a result, even when game balls flow down from both the left and right directions with respect to the front area of the introduction port 15, there is a difference in the guide speeds of both game balls, and there is no ball clogging. Is guided to the introduction port 15.
