Description

  The present invention relates to a game board unit, a speed adjusting member, and a game machine, and more particularly to a game board unit having a function of adjusting the speed of a game medium passing through a passage formed in a game area.

  In a pachinko machine, a ball that has been shot down flows down a game area (an area formed on or near the game board surface for realizing a game or production by the flow of the ball). During the flow-down process, the ball rolls while colliding with obstacle nails (also called gauges) and windmills in the game area, and the flow-down direction changes. As a result, if a ball wins various winning holes arranged on the game area, a predetermined prize ball is paid out. On the other hand, if a ball flows into the out port without winning any prize hole, no prize ball is paid out. . The player enjoys the game by demonstrating his / her skill in the ball or using the chance of the ball flowing down and expecting to win a prize and give away a prize ball.

  In this pachinko machine, there is a pachinko machine in which a ball passage for passing one ball is arranged in the game area. The ball passage accepts a ball flowing down the game area from the passage entrance and guides it to the passage exit while regulating the traveling direction so as to guide it in a predetermined direction (passing direction), and gives the player interest by the passage mode Is.

  For example, there is a ball passage that regulates the horizontal direction or the vertical direction of a sphere flowing down the game area, and is configured to guide the passage from the passage entrance to the passage exit while regulating the flow direction of the sphere that has entered (for example, , See Patent Document 1). In addition, the passage entrance and passage exit of the ball passage formed in a tube shape are arranged at completely different positions in the game area so that the ball entering the ball passage from the entrance appears from an unexpected place. There is also.

  By this ball passage, not only a game effect realized by the ball flowing down in the game area, but also a game effect by guiding the ball from the entrance to the exit can be realized. In the guiding process, the ball passing through the ball passage can travel in the ball passage without being affected by other balls flowing down in the game area.

  On the other hand, in some game areas of the pachinko machine, there is one in which a symbol display device is arranged. This symbol display device is arranged approximately at the center of the game board surface and has a display screen such as a liquid crystal display to provide a symbol variation game. In recent years, since the symbol display device tends to increase in size, an area in which a ball can actually flow down in a game area (hereinafter referred to as a flow-down area) has become relatively small.

  For this reason, for example, there has been proposed an arrangement in which a ball passage is formed in the upper part of the symbol display device located substantially in the center of the game area, and the flow-down areas are distributed to the left and right. In other words, the sphere is configured to flow down the flow area on the left side of the symbol display device according to the launch intensity of the sphere, or to flow down the flow area on the right side through the ball passage. You can enjoy both of the flow down.

  However, if there is a difference in the passing speed of the spheres passing through the sphere passage, the front and rear spheres may interfere with each other, which may adversely affect the sphere passage mode. For example, if the speed of the ball that entered the ball path first is slow and the speed of the ball that entered the ball path later is high, the rear ball catches up with the previous ball in the ball path and the two collide. There is a possibility that.

  On the other hand, when the speed of the preceding sphere is high and the speed of the succeeding sphere is slow, the distance between the two may be too far. For example, when a winning opening that opens and closes for a short time is arranged on the downstream side of the ball passage, if the distance between the balls passing through the ball passage is too far, the player will expect within the opening time. The number of balls may not flow in and the player may be discouraged.

  Therefore, by passing a plurality of spheres at the same speed in the sphere passage, it is possible to prevent interference between the preceding sphere and the succeeding sphere, or prevent the distance between them from being too far apart. There was a need for a pachinko machine that can be used to enjoy the passage of the ball in the ball passage as expected.

  The present invention has been made in view of the above circumstances, and by averaging the passing speed of the spheres in the spherical passage, it is caused by the large speed difference between the spheres passing through the spherical passage. It is an exemplary problem to provide a game board unit, a speed adjustment member, and a game machine that can prevent various adverse effects that occur.

  In order to solve the above-described problems, a game board unit as an exemplary aspect of the present invention includes a game board in which a game area for realizing a game by flowing down a game medium is configured on the surface side, and a game board in the game area. A game board unit having an inflow port through which a game medium is allowed to flow, wherein a passage that allows one game medium to pass along a plurality of passage trajectories is disposed in the game area; In addition, by contacting the game medium passing through the passage along one passage locus among the plurality of passage locus so that an external force acts in a predetermined direction different from the passage direction in the passage, A speed adjusting member for adjusting the speed of the game medium in the passing direction is arranged.

  Since the speed adjusting member is arranged in the passage, the speed of the game medium passing through the passage is adjusted, and the passage speed can be averaged. Therefore, even when a plurality of game media passes through the passage continuously, the preceding game media and the subsequent game media collide or interfere with each other by securing an appropriate space between the game media. Can be prevented, and various adverse effects such as clogging and reversing of game media can be prevented. In addition, since it is possible to prevent an interval between game media passing through the passage from being excessively separated, for example, a player is provided such that the flow of game media to a winning opening arranged downstream of the passage is performed in a balanced manner. It can also be as expected.

  More specifically, in this game board unit, the speed adjusting member applies an external force in a predetermined direction different from the passing direction to a game medium passing through the passage at a relatively high speed along one passing locus. By abutting so as to act, a speed component in the passing direction (passing speed) is positively reduced while giving a speed component in a predetermined direction. As a result, the passing speed of the game medium passing through the passage at a relatively high speed can be reduced, which can contribute to averaging the passing speed as a whole. Here, the game medium is typically a ball (pachinko ball) used in a pachinko machine as a game machine. Of course, in a coin game or the like where coins flow down the game area, the coin Corresponds to a game medium.

  In addition, as a channel | path, it is a tube-shaped thing, for example, Comprising: The whole circumference | surroundings in the surface (henceforth an orthogonal cross section) orthogonal to the passage direction of a game medium may be enclosed. For example, in a pachinko machine, the left and right direction or the up and down direction of a sphere may be restricted in the game area, and the passage may be configured in cooperation with the game board surface (front surface) and the front glass in the front and rear direction. In any case, the cross-sectional area of the passage in the orthogonal cross section has a margin with respect to the outer dimensions of the game medium, and it is necessary that the game medium can pass through the passage in a plurality of passages.

  Note that one passage locus means a passage locus that can be taken by a game medium that passes through the passage at a relatively high speed. For example, in the case of a concept of one passing trajectory and another different passing trajectory, when the one passing trajectory is “the trajectory that the game medium has passed along one inner wall of the passage”, the other May be a “trajectory through which the game medium has passed along the other (opposite) inner wall of the passage”. In addition, when one passing trajectory is “the trajectory that the game medium has passed along the inner wall of the passage”, the other passing trajectory is “the trajectory that the game medium has passed through the approximate center of the passage without being along the inner wall. It may be. Of course, when one passing trajectory is “a trajectory in which the game medium has passed through the approximate center of the passage without being along the inner wall”, the other passage trajectory is “a trajectory in which the gaming medium has passed along the inner wall of the passage. It may be.

  For example, when a relatively high-speed game medium enters a passage along a “trajectory along one inner wall of the passage” as one passage locus, the predetermined medium speed differs from the passage direction by contacting the speed adjusting member. As a result, the trajectory may be shifted and the trajectory of the game medium may become “a trajectory along the inner wall on the other side (opposite side) of the passage” as another pass trajectory.

  The speed adjustment member may have an inclined portion that causes the game medium passing through the passage along one passage trajectory to collide against the inner wall of the passage. Since the inclined portion causes the game medium to collide with the inner wall of the passage, the energy possessed by the game medium is reduced by the collision, and the passing speed can be reduced more efficiently and in a short time. Therefore, the passing speed of the game medium passing through the passage can be averaged more efficiently and in a short time.

  It should be noted that the amount of decrease in the speed component in the passing direction of the game medium can be adjusted by adjusting the inclination angle of the inclined portion and the maximum protrusion amount into the passage. For example, if the inclination angle is about 5 ° to 25 °, the game medium can smoothly enter the inclined portion, and it is possible to reduce generation of noise and damage to the inclined portion during entry. Here, the maximum protrusion amount is of course limited to a range in which the game medium can pass through the passage. For example, when the height dimension Hb of the game medium and the height dimension Hc of the ball passage in the orthogonal cross section are set, the maximum protrusion amount Hp <Hc−Hb.

  The speed adjusting member abuts against the game medium passing through the passage along another passage locus different from the one passage locus so that an external force acts in the passage direction and another direction different from the predetermined direction. May be.

  Since the direction of the external force acting on the game medium passing through the passage along one passage trajectory is different from the direction of the external force acting on the game medium passing through the passage along the other passage locus, It can set so that the passage speed reduction effect with respect to each may differ. Therefore, when the passing speed of the game medium passing through the passage along one passage trajectory is different from the passing speed passing through the passage along the other passage trajectory, the passing speed of each gaming medium is appropriately set. It can reduce, and can contribute to averaging of various passage speeds. The passage may be arranged along the periphery of the game area. This makes it possible to average the passing speed of the game media passing through the passages arranged along the periphery of the game area.

  For example, in a gaming machine such as a pachinko machine, rail decorations are arranged around the gaming area so as to surround the gaming area. Then, the ball that has been fired enters the game area vigorously along the inner surface of the rail decoration. By disposing the passage along the periphery of the game area, the passing speed of the ball fired can be averaged in the passage. Therefore, both strongly and weakly launched spheres can average the passing speed in the passage, so even if the sphere is continuously fired, it prevents the collision and collision of the spheres before and after. The space between the spheres passing through the passage can be appropriately secured.

  In this pachinko machine, for example, the inner surface of the rail decoration constitutes the upper inner wall of the passage, and a symbol display device or a decorative accessory (so-called center decoration) around it is arranged at the approximate center of the game area. A lower inner wall is formed, and a passage is formed at the periphery of the game area by the upper inner wall and the lower inner wall.

  A plurality of speed adjustment members are arranged along the periphery so as to protrude from the periphery of the game area toward the inside of the game area, and the protrusion that contacts the game medium passing through the passage along the other passage trajectory You may have.

  By disposing a plurality of simple structural members called protrusions along the periphery of the game area, the velocity component in the passing direction of the game medium passing through the passage at a relatively high speed along one passing trajectory can be easily reduced. Can be made. The effect of reducing the passing speed of the game medium can be easily adjusted by adjusting the outer shape of the protrusion, the amount of protrusion into the passage, or the number of the protrusions. Further, by adjusting the protrusion length of the protrusion (that is, the protrusion length), it is possible to freely adjust the reduction amount of the speed component in the passing direction according to the passing trajectory of the game medium.

  For example, in the example of the pachinko machine described above, when the protrusion is arranged so as to protrude from the inner surface (upper inner wall) of the rail decoration toward the decorative accessory (lower inner wall), the protrusion length of the protrusion Can be configured to reduce only the velocity component in the passing direction of a relatively high-speed sphere passing through the passage along the upper inner wall. On the other hand, if the protrusion length of the protrusion is increased, in addition to the relatively high-speed sphere that passes through the passage along the upper inner wall, the velocity component in the passing direction of a medium-speed sphere that passes through the approximate center of the passage is also provided. It can be configured to decrease.

  Plural projections are arranged on both sides of the game medium in the direction orthogonal to the surface of the game board so that the projections arranged on one side and the projections arranged on the other side are staggered and arranged on one side The distance between the projected portion arranged on the other side and the projected portion arranged on the other side is larger than the outer dimension of the game medium, and in the passing direction between the projected portion arranged on one side and the projected portion arranged on the other side. The projection interval with respect to the orthogonal plane may be smaller than the outer dimension of the game medium.

  Here, the interval between the protrusions disposed on one side and the protrusions disposed on the other side is a linear distance between the protrusions on both sides. Moreover, the projection interval with respect to the plane orthogonal to the passing direction is the interval between the two side projections when the projections on both sides are projected onto the orthogonal plane.

  Since the projection interval of the protrusions arranged on both sides is smaller than the outer dimension of the game medium, the game medium along the other passage trajectory cannot advance straight along the passage direction. However, since the protrusions arranged on both sides are staggered and the interval is larger than the outer dimension of the game medium, the game medium can pass through the passage in a zigzag manner.

  By arranging the protrusions in this way, so-called zigzag running can be performed on the game medium passing through the passage along other passage trajectories, and the speed component in the passage direction can be reduced more efficiently. Can be made.

  A gap may be arranged between adjacent protrusions arranged on at least one of the one side or the other side.

  A gap is disposed between the protrusions, and the player can visually recognize the game medium passing through the passage through the gap. Since the behavior of the game medium in the aisle can be confirmed, the player can obtain interest with a sense of security.

  A first big prize opening that performs an opening operation to allow a game medium to flow in when a first special game is generated, and an opening operation that allows a game medium to flow in when a second special game that is different from the first special game occurs The second big prize opening, the first start port that triggers the first special game lottery by the inflow of game media, the state of the game media can be changed to be inflowable or inflowable, A state in which a state change lottery is performed as to whether or not the state of the second start port that allows the start of the second special game due to the inflow of the medium and the state of the second start port to enter the state in which the game medium can be input. The game lottery means further includes a change lottery means and a pass area that triggers the status change lottery by the status change lottery means when the game medium passes, and the pass area, the second start opening, and the second big prize opening are Arranged downstream of the passage in the flow direction It may be.

  In this way, by arranging the passage area, the second start opening and the second big prize opening on the downstream side of the passage, the game medium whose passage speed is averaged by the passage becomes the passage area, the second start opening. And it will reach the 2nd big prize opening. Therefore, it is possible to maintain a suitable distance between the plurality of game media in the vicinity of the passing area, the second start opening, and the second special winning opening, and to be too close to interfere with each other or to be separated too much. Can be prevented.

  In particular, when the second start opening and the second big prize opening are changed between a state in which game media can flow in and a state incapable of flowing in by opening and closing operations, the open state (a state in which game media can flow in) )) Is a short time, the game media are present in the vicinity of the second starting opening and the second big prize opening at an appropriate interval, so that the game media can be placed on them as expected by the player. Can flow in.

  As described above, as a gaming machine capable of realizing the first special game (also referred to as a type 1 big hit or symbol variation big hit) and the second special game (also referred to as a type 2 big hit or a bonus hit for a feature), For example, one type and two types of pachinko machines described later can be conceptualized.

  According to another exemplary aspect of the present invention, a speed adjusting member is provided on a surface side of a game board so that one game medium can be passed along a plurality of passage trajectories and a game can be played by the flow of the game medium. A speed adjusting member that adjusts the speed of the game medium and that passes through the passage along one passage trajectory of the plurality of passage trajectories. The speed of the game medium in the passing direction is adjusted by contacting the game medium so that an external force acts in a predetermined direction different from the passing direction in the passage.

  By arranging this speed adjusting member in the passage in the game area, the passing speed of the game medium passing through the passage is adjusted, and the passing speed can be averaged. Therefore, even when a plurality of game media passes through the passage continuously, the preceding game media and the subsequent game media collide or interfere with each other by securing an appropriate space between the game media. Can be prevented, and various adverse effects such as clogging and reversing of game media can be prevented. In addition, since it is possible to prevent an interval between game media passing through the passage from being excessively separated, for example, a player is provided such that the flow of game media to a winning opening arranged downstream of the passage is performed in a balanced manner. It can also be as expected.

  More specifically, the speed adjusting member abuts against a game medium that passes through the passage at a relatively high speed along one passage trajectory so that an external force in a predetermined direction different from the passing direction acts. Thus, the passing speed is actively reduced while giving a speed component in the predetermined direction. As a result, the passage speed of relatively high-speed game media is reduced, and it can contribute to averaging the passage speed of game media as a whole.

  A gaming machine as still another exemplary aspect of the present invention relates to the above-described gaming board unit, a frame that holds the gaming board unit so that the gaming area is visible to the player, and the gaming board unit. It has a front transparent plate arranged at a certain distance or more in front of it, and a launch unit that launches a game medium toward a game area.

  In this gaming machine, the speed of the game medium passing through the passage is adjusted, and the passing speed can be averaged. Therefore, even when a plurality of game media passes through the passage continuously, the preceding game media and the subsequent game media collide or interfere with each other by securing an appropriate space between the game media. Can be prevented, and various adverse effects such as clogging and reversing of game media can be prevented. In addition, since it is possible to prevent an interval between game media passing through the passage from being excessively separated, for example, a player is provided such that the flow of game media to a winning opening arranged downstream of the passage is performed in a balanced manner. It can also be as expected.

  More specifically, the speed adjusting member abuts against a game medium that passes through the passage at a relatively high speed along one passage trajectory so that an external force in a direction different from the passing direction acts. The passing speed is actively reduced while giving a speed component in the predetermined direction. As a result, the speed of the relatively high-speed game medium is reduced, which can contribute to the averaging of the passing speed of the game medium as a whole.

  As a result, a time margin for the player to enjoy the passage mode of the game medium passing through the passage is created, and the effect of further increasing interest is exhibited. In addition, since the transit time required for the game medium to pass through the passage can be averaged, the passage of the game medium in the passage and other effects, for example, effects using sound effects or decorative lights, etc. Cooperation will be smooth. It is possible to facilitate the cooperative control between the passage of the game medium and the effect by the decoration light, etc., or to reduce the shift in the timing of the cooperation and increase the effect.

  Further objects and other features of the present invention will become apparent from the preferred embodiments described below with reference to the accompanying drawings.

  According to the present invention, the speed of the game medium passing through the passage is adjusted, and the passing speed can be averaged. Therefore, even when a plurality of game media passes through the passage continuously, the preceding game media and the subsequent game media collide or interfere with each other by securing an appropriate space between the game media. Can be prevented, and various adverse effects such as clogging and reversing of game media can be prevented. It is also possible to prevent the game media passing through the passage from being separated too much. Furthermore, it is possible to smoothly link the passage of the game medium in the passage and other effects, thereby facilitating the cooperation control of the game effects and increasing the effect.

  The symbol display device 7a is composed of, for example, a liquid crystal display device, an organic EL display, an LED, etc., and is arranged so that the player can see from the game board surface 6a side, and on the display screen (video display surface) 7b. The video display is performed. On the display screen 7b, for example, a display symbol 7c composed of three-digit numbers or characters is displayed as an image so as to rotate or stop. In addition, for example, an effect image as a story tailoring image by a character or the like is also displayed on the display screen 7b.

  When the ball 23 is launched by a ball launching device (not shown), the ball 23 travels along the inner surface 26a of the rail decoration 26 and reaches the upper part in the game area 6b. Thereafter, the ball 23 collides with the gauge 27 and flows down in the game area 6b. Some of the balls 23 flow into the normal winning opening 28 to trigger a certain number of prize balls to be paid out. Without flowing in, it flows into the out port 30 located at the lowermost part in the game area 6 b and is discharged to the outside of the pachinko machine 2.

Is opened for a predetermined time and a bonus game is generated. During the opening time, if the succeeding ball 23 flows into the front portion of the symbol display device 7a from the two kinds of big winning opening 8a and wins the V winning opening 35, the central big winning opening 31 is opened and the big hit is You can enjoy the continuation of the game.

  FIG. 2 shows a partially enlarged view in which the ball passage 37 portion in the pachinko machine 2 is enlarged. The spherical passage 37 has a substantially rectangular cross-sectional shape in a cross-section (orthogonal plane) orthogonal to the sphere passage direction (see also FIG. 4), and a part of the inner side surface 26a of the rail ornament 26 is the upper wall surface. 37a is comprised along the periphery of the game area | region 6b. A part of the upper part of the center decoration 8 constitutes the lower side wall surface 37b of the ball passage 37, a part of the game board surface 6a constitutes the rear side wall surface 37c, and a part of the front glass 10 constitutes the front side wall surface 37d. (See also FIG. 4). The sphere 23 is a sphere having a diameter of about 11 mm, and the sphere passage 37 has a vertical inner dimension (that is, a distance from the upper wall surface 37a to the lower wall surface 37b) within a range in which one sphere 23 can pass. It is made larger than the diameter. In the ball passage 37, the direction in which the upper wall surface 37a and the lower wall surface 37b face each other is the vertical direction (height direction), and the direction in which the rear wall surface 37c and the front wall surface 37d face each other is the front and rear direction (depth direction). That's it.

  A speed adjusting member 17 is attached to the upper wall surface 37 a of the ball passage 37. FIG. 3 shows an external perspective view of the speed adjusting member 17. The speed adjusting member 17 has an inclined portion 17b in the vicinity of the tip of the main body portion 17a. The inclined portion 17b has a function of contacting the sphere 23 passing through the spherical passage 37 along the upper wall surface 37a so that an external force acts, and causing the sphere 23 to collide with the lower wall surface 37b. Yes. Therefore, it inclines so that thickness may increase gradually from the upper side wall surface 37a along the passage direction of the bulb | ball 23, and the inclination | tilt angle (theta) is about 20 degrees.

  The main body portion 17a is a plate-like portion attached along the inner side surface 26a, and an inclined portion 17b is protrusively disposed near the tip of the main body portion 17a, and a plurality of protrusions 17c and 17d are protruded along both side portions. . The main body portion 17 a substantially constitutes an upper wall surface 37 a instead of the inner side surface 26 a in the spherical passage 37.

  FIG. 4 is a schematic cross-sectional view showing the spherical passage 37 cut along an orthogonal plane. The maximum protrusion amount Hp of the inclined portion 17b into the sphere passage 37 is Hp <Hc−Hb using the diameter Hb of the sphere 23 and the height dimension Hc of the sphere passage 37. Even at the maximum protrusion position, The sphere 23 can pass through the sphere passage 37.

  The sphere 23 can pass along a plurality of trajectories in the sphere passage 37. That is, the sphere 23 having a relatively low launch intensity and a low velocity has a low momentum, enters the sphere passage 37 along the lower wall surface 37b, and passes along the passage locus T1 in FIG. In this case, the sphere 23 does not come into contact with the inclined portion 17 b of the speed adjustment member 17.

  On the other hand, the sphere 23 having a relatively high firing strength and a high velocity has a strong momentum, enters the ball passage 37 along the upper wall surface 37a, and passes along the passage trajectory T2 in FIG. In this case, the moving direction of the sphere 23 is changed downward (a predetermined direction different from the passing direction) by the inclined portion 17 b, and as a result, the velocity component in the passing direction along the spherical path 37 is reduced. Furthermore, since the sphere 23 is caused to collide with the lower wall surface 37b, energy is lost due to the collision and the passing speed is further reduced.

  As a result, the passing speed of the sphere 23 that is strongly fired and has a high speed is reduced, the speed difference with the sphere 23 having a slow passing speed is reduced, and the passing speed is averaged when the sphere passage 37 passes. It becomes. Therefore, it is possible to prevent the preceding sphere 23 and the succeeding sphere 23 from causing interference or collision between the spheres, or the passage interval between them being too far apart. At this time, the sphere 23 passing through the spherical passage 37 along the passage trajectory T2 passes through the passage 37 along the passage trajectory T1 from the middle of the spherical passage 37 by contacting the inclined portion 17b. .

  Since the plurality of spheres 23 pass through the sphere passage 37 while securing an appropriate interval at an averaged speed, the occurrence of clogging in the sphere passage 37 can be prevented. Moreover, since the space | interval of the several ball | bowl 23 which flows down the right side area | region 16b after passing the ball | bowl channel | path 37 is ensured moderately, the ball | bowl which flows into each within the open time of the 2nd type large winning opening 8a and the opening / closing start port 29b Variation in the number can be reduced. It is possible to prevent the occurrence of a situation in which many spheres 23 flow in unexpectedly within the opening time, or almost no spheres 23 flow in contrary to expectations.

  When the firing strength is medium, the sphere 23 does not extend along the upper wall surface 37a or the lower wall surface 37b, but substantially along the vicinity of the center of the ball passage 37 (that is, along the passage trajectory T3 in FIG. 4). Passes through the ball passage 37. In this case, since the sphere 23 does not come into contact with the inclined portion 17b, the effect of reducing the velocity component in the passing direction by the inclined portion 17b cannot be obtained. The speed of the sphere 23 along such a trajectory T3 is adjusted by the protrusions 17c and 17d of the speed adjusting member 17.

  Note that each of the passage trajectories T1 to T3 can be one passage trajectory or another passage trajectory. That is, when the passage trajectory T1 is one passage trajectory, the passage trajectory T2 and the passage trajectory T3 are other passage trajectories. Further, when the passing trajectory T2 is one passing trajectory, the passing trajectory T1 and the passing trajectory T3 are other passing trajectories. When the passing trajectory T3 is one passing trajectory, the passing trajectory T1 and the passing trajectory are used. T2 is another passing trajectory.

  A plurality of the projecting portions 17c and 17d are arranged along both side portions of the main body portion 17a. As a result of arranging the speed adjusting member 17 in the ball passage 37, the protrusion 17c is positioned on the back side (game board surface 6a side), and the protrusion 17d is positioned on the front side (front glass 10 side). Then, the protrusions 17c and 17d are arranged so as to protrude from the inner side surface 26a toward the center ornament 8 (that is, from the periphery of the game area 6b toward the inside of the game area 6b). .

  As shown in FIG. 4, the projecting portions 17 c and 17 d are arranged so as to protrude from the main body portion 17 a to a middle portion in the height direction of the spherical passage 37. Therefore, for example, the side surface portion 17e comes into contact with the sphere 23 passing through the spherical passage 37 along the passage locus T2, and the tip portion 17f thereof is against the sphere 23 passing through the spherical passage 37 along the passage locus T1. It comes to contact. A gap G is formed between adjacent protrusions 17d that are arranged on the front side. Therefore, even when the ball 23 is passing through the ball passage 37, the player can visually recognize the ball 23 passing through the gap G.

  FIG. 5 shows a partial cross-sectional view in which the plan view of the spherical passage 37 seen from above is partially taken as a cross-section. In the spherical passage 37, the protrusions 17c and the protrusions 17d are arranged so as to alternate with each other, and the shortest linear distance (interval) L1 between the protrusions 17c and 17d is larger than the diameter of the sphere 23. It is a large size. However, the projection inner dimension (projection interval) L2 between the projection 17c and the projection 17d in the orthogonal plane is smaller than the diameter of the sphere 23.

  When the sphere 23 passes through the ball passage 37 along the passage trajectory T1 (relatively low speed), it is only in contact with the tip 17f of the projections 17c and 17d, so the speed is hardly reduced. It passes through the ball passage 37. However, when the sphere 23 passes the sphere passage 37 along the passage trajectory T2 (relatively high speed), the traveling direction of the sphere 23 is changed by the inclined portion 17b, and the sphere 23 collides with the lower wall surface 37b. As a result, the velocity component in the passing direction decreases.

  On the other hand, when the sphere 23 passes the sphere passage 37 along the passage trajectory T3 (that is, at a medium speed), the sphere 23 does not contact the inclined portion 17b. However, the sphere 23 comes into contact with the side surface portions 17e of the projecting portions 17c and 17d disposed on both side portions of the main body portion 17a. The sphere 23 traveling along the passage trajectory T3 cannot travel as it is along the passage direction, and passes through the spherical passage 37 while performing so-called zigzag traveling between the protrusions 17c and 17d. Therefore, the traveling direction is changed while external force is applied to the front direction or the depth direction (another direction different from the passing direction and the downward direction) by the protrusions 17c and 17d, and the sphere 23 reduces the velocity component in the passing direction. It will be.

  It should be noted that the effect of reducing the passing speed can be adjusted by adjusting the shape and length of the protrusions 17c and 17d. Therefore, the speed adjustment effect for the sphere 23 passing along the passage trajectory T2 and the speed adjustment effect for the sphere 23 passing along the passage trajectory T3 are set differently, and the spheres along the respective passage trajectories T2, T3. 23 can be optimized according to the approach speed.

  As described above, by arranging the inclined portion 17b and the protrusions 17c and 17d in the spherical passage 37, both the relatively fast sphere 23 and the medium speed sphere 23 have velocity components in the passing direction. Is reduced, and the speed difference from the speed of the relatively slow sphere 23 is reduced. As a result, the passage speeds of the plurality of spheres 23 passing through the sphere passage 37 are averaged, and interference and collisions caused by the front and rear spheres 23 and an excessive expansion of the front and rear sphere intervals can be prevented.

  The inclined portion 17b abuts only on the sphere 23 that has entered at a relatively high speed along the passage trajectory T2, and exhibits a function of effectively reducing the passing speed of the high-speed sphere 23. On the other hand, the protrusions 17c and 17d are in contact with the sphere 23 that has entered at a medium speed or a relatively low speed, or the sphere 23 that has entered at a high speed but has been reduced in speed by the inclined portion 17b. The function of effectively reducing the passing speed of 23 is exhibited. For example, when the inclined portion 17b is not disposed, the sphere 23 that has entered the ball passage 37 at a relatively high speed along the passage trajectory T2 directly contacts the protrusions 17c and 17d without reducing the passage speed. Then, the sphere 23 may be rebounded in the reverse direction of the traveling direction by the protrusions 17c and 17d, and on the contrary, interference between the spheres 23 or traffic congestion due to the collision may be induced. However, according to the speed adjusting member 17, the speed of passage of the high-speed sphere 23 is reduced by the inclined portion 17b before coming into contact with the protruding portions 17c and 17d, so that the protruding portions 17c and 17d and the inclined portion 17b are The function exerted in cooperation effectively performs the speed averaging of the sphere 23, smooth flow, securing an appropriate interval, and the like.

  The front glass 10 is a transparent plate that is spaced apart from the game board 6 by a certain distance or more. The front glass 10 is formed of transparent flat glass and is held on the back side of the decorative frame 12, and has a function of forming a flow-down space in which the ball 23 flows down between the game board 6 and the player through the front glass 10 to play the game board 6. A function of ensuring visibility so that the player can visually recognize the player, and a function of preventing unauthorized access so that the player cannot illegally access (contact) the game board 6.

  The launching unit is for firing (bulleting) the ball 23 sent from the upper plate 14a as a part of the storage tray 14 to the firing position by the ball supply device (not shown) toward the upper part of the game area 6b. It is. The launch unit includes, for example, a launcher that shoots the ball 23 at the launch position, a launch motor that drives the launcher, a launch spring that urges the launcher to generate a ball force, and the like. It is attached to the machine casing 9. For launching the ball by the launch unit, a launch handle 15 is provided below the front surface of the pachinko machine 2 to realize on / off of the launch of the ball and adjustment of the launch intensity based on the operation of the player.

  Depending on the firing strength of the launch unit, the sphere 23 can be passed through the ball passage 37 or not. That is, if the firing strength is weakened, the sphere 23 starts to flow without reaching the ball passage 37 and flows down the left region 16a. When the firing strength is slightly higher than that, the sphere 23 enters the ball passage 37, but the velocity is relatively slow and the ball 23 passes through the ball passage 37 along the passage trajectory T1.

  When the firing intensity is slightly higher, the sphere 23 enters the ball passage 37 at a medium speed and passes through the ball passage 37 along the passage locus T3. The sphere 23 travels in a zigzag manner while contacting the protrusions 17c and 17d and passes through the sphere passage 37, and the velocity component of the sphere 23 in the passing direction is reduced. When the firing strength is even stronger, the sphere 23 enters the ball passage 37 at a relatively high speed and passes through the ball passage 37 along the passage locus T2. The sphere 23 changes its traveling direction downward by the inclined portion 17b and collides with the lower side wall surface 37b, and the velocity component of the sphere 23 in the passing direction is reduced.

  The storage tray 14 is a tray member disposed on the front surface of the pachinko machine 2 to store the player's ball, and in the first embodiment, has an upper tray 14a and a lower tray 14b. . The upper plate 14a has a ball discharge button 14c and is disposed below the game board 6, that is, a lower portion of the decorative frame 12, and the lower plate 14b is disposed further below the upper plate 14a.

  Next, a gaming method in the pachinko machine 2 will be briefly described.

<Design variation game>
When the player operates the firing handle 15, the ball is fired, and the ball 23 is fired along the firing rail (not shown) and the inner surface 26a of the rail decoration 26 to reach the upper part of the game area 6b. In the symbol variation game, the player aims at the inflow of the sphere 23 into the central starting port 29a, and adjusts the rotation amount of the launch handle 15 so that the launch strength is weakened so that the sphere 23 flows down mainly in the left region 16a. And launch a ball. Thereby, before the sphere 23 reaches the sphere passage 37, the sphere 23 starts to fall from the inner side surface 26a and flows down the left region 16a. The sphere 23 that has flowed down the left region 16a flows into, for example, the normal winning opening 28 or into the central starting opening 29a. Of course, in this pachinko machine 2, the ball 23 that has flowed down the right region 16b is also arranged so that it can reach the central starting port 29a. You may fire.

  When the ball 23 flows into the central starting port 29a, the symbol display device 7a starts rotating the display symbol 7c (the first special game lottery). When the display symbol 7c is stopped and displayed in a predetermined jackpot mode (for example, “7, 7, 7”), a symbol variation jackpot is generated and the central jackpot 31 is opened. Then, a large amount of spheres 23 flow into the central prize opening 31, and a large amount of prize balls are paid out.

  The opening / closing operation of the central special winning opening 31 is repeatedly performed a predetermined number of times, and then the symbol variation game is ended. For example, “2 · 2 · 2”, “6 · 6 · 6”, “7 · 7 · 7”, and the like are used as the stop mode of the display symbol 7c for the symbol variation big hit. When the symbol variation jackpot game in some of the modes (for example, “7, 7, 7”) is completed, an accessory game is started thereafter.

<Combination game>
When the bonus game is started, the player aims to pass the ball 23 to the passing gate 33 and adjusts the rotation amount of the firing handle 15 so that the firing strength becomes strong so that the ball 23 flows down in the right region 16b. And launch a ball. Thereby, the sphere 23 enters the sphere passage 37 along the inner side surface 26a, passes through the sphere passage 37, and reaches the right region 16b. When the firing strength at this time is relatively weak enough that the sphere 23 finally reaches the sphere passage 37, the sphere 23 is formed on the lower side wall surface formed on the center decoration 8 before the speed adjusting member 17. It falls onto 37b and passes through the spherical passage 37 at a relatively low speed along the passage trajectory T1. At this time, since the tip end portion 17f of the projecting portions 17c and 17d is in contact with the sphere 23, the passing speed is hardly reduced.

  If the firing intensity of the subsequently fired sphere 23 is stronger than the firing intensity of the preceding sphere 23, the sphere 23 reaches the sphere passage 37 at a relatively high speed. The sphere 23 enters the sphere passage 37 along the passage trajectory T2, but is caused to collide with the lower wall surface 37b by the inclined portion 17b of the speed adjusting member 17, and the passing speed thereof passes through the preceding sphere 23. It is reduced to a speed close to the speed. Therefore, the spheres 23 catch up with the preceding sphere 23 and do not collide with each other, and the two spheres 23 pass through the sphere passage 37 at an equal speed while maintaining an appropriate interval. Generation | occurrence | production of the ball clogging in the ball | bowl channel | path 37, the reverse return of the succeeding ball | bowl 23 by a collision, etc. is prevented effectively.

  Further, when the firing intensity of the subsequently fired sphere 23 is fired at a medium firing intensity, it reaches the ball passage 37 at a medium speed. The ball 23 enters the ball path 37 along the passage trajectory T3 without being along the inner surface 26a or the center decoration 8, but is zigzag-run by the protrusions 17c and 17d of the speed adjustment member 17, The passing speed is reduced to a speed close to the passing speed of the preceding two spheres 23. Therefore, these three spheres 23 pass through the ball passage 37 at an equal speed while maintaining a proper interval without catching up with the preceding sphere 23 and causing collision between the spheres or being too far away from the preceding sphere 23. Will pass.

  The sphere 23 that has passed through the sphere passage 37 flows down the right region 16 b, and some passes through the passage gate 33. When the lottery result obtained by the state change lottery means is a win, the opening / closing start port 29b is opened for a certain period of time. Due to the speed adjustment function of the spherical passage 37, the intervals between the plurality of spheres 23 flowing down the right region 16b are moderate intervals, and the spheres 23 are not separated too much. Therefore, when the opening / closing start port 29b is opened, the following ball 23 flows down to the vicinity of the opening / closing start port 29b, and the player can sufficiently acquire the opportunity for the flow of the ball 23 into the opening / closing start port 29b.

  When the ball 23 flows into the opening / closing start port 29b, a big hit game is generated, and the two kinds of big winning ports 8a are opened for a predetermined time. Since the interval between the plurality of spheres 23 flowing down the right region 16b is an appropriate interval, the following sphere 23 flows down to the vicinity of the two-type big prize opening 8a when the two-type big prize opening 8a is opened, The player can fully acquire the opportunity for the inflow of the ball 23 to the two-type big prize opening 8a.

  Then, if the ball 23 flows into the two-type big prize opening 8a and wins the V prize opening 35 arranged in the center bonus 7, the central big prize opening 31 is opened as the bonus game continues. Then, a large amount of balls 23 flow into the central grand prize opening 31 and a large bonus game can be continuously enjoyed while a large amount of prize balls are paid out. Since the central big prize opening 31 is arranged in the vicinity of the substantially lower center of the game area 6b, the sphere 23 flowing down the left area 16a and the sphere 23 flowing down the right area 16b can flow in. Therefore, in order to continue the big hit game, it is not necessary to adjust the rotation amount of the firing handle 15 so that the firing strength is weakened and to cause the ball 23 to flow down to the right region 16b.

  In the vicinity of the passage exit of the ball passage 37, a collision portion 26b for allowing the ball 23 after passing through the ball passage 37 to flow downward is disposed. When the speed adjusting member 17 is not provided, the ball 23 collides with the collision portion 26b at a high speed. Therefore, in order to prevent mutual damage and noise, the collision portion 26b has a separate impact mitigation / noise absorption function. It was necessary to arrange an elastic member such as urethane rubber. However, the pachinko machine 2 according to the present embodiment has the speed adjusting member 17 in the ball passage 37, and the ball 23 after passing through the ball passage 37 is averaged at a relatively low speed, so that the collision portion 26b. There is no need to separately provide an elastic member.

  The speed adjusting member 17 is preferably made of nylon resin such as nylon 6 from the viewpoint of durability and wear resistance. However, other materials may be used as long as the above characteristics are satisfied. For example, resins such as polycarbonate and polyacetal and glass fiber reinforced resins thereof may be used.

  As mentioned above, although preferable embodiment of this invention was described, this invention is not limited to these, A various deformation | transformation and change are possible within the range of the summary. For example, in the present embodiment, the rail decoration 26 and the speed adjustment member 17 are described as separate bodies. Of course, the rail decoration 26 itself is provided with an inclined portion or a protrusion, and exhibits a speed adjustment function. Also good. Further, in the present embodiment, the case where the pachinko machine has the ball passage and the speed adjustment member near the periphery of the game area has been described, but the ball passage and the speed adjustment member are arranged at other positions in the game area. Of course, for example, this speed adjusting member is arranged in a tube-shaped ball passage (so-called warp passage) for transferring the ball from a specific position in the game area to another position. Also good.

  Further, in this embodiment, as one type and two types of pachinko machines, the game area is separated into a right area and a left area, and a ball that has passed through the ball passage is a passing gate, an opening / closing start port, and a two-type big prize opening. Although the structure that reaches the right area where is placed is described, of course, the game area may not necessarily be separated into the right side and the left side. In short, a ball passage is arranged in the game area, and a passage gate, an opening / closing start port and two kinds of large passages so that a ball passing through the ball passage can reach the passage gate, the opening / closing start opening and the two kinds of big prize winning openings. It is only necessary that the winning opening is arranged on the downstream side of the ball passage.

It is a front view of the pachinko machine concerning Embodiment 1 of the present invention. It is the elements on larger scale which expanded the ball passage part of the pachinko machine shown in FIG. It is an external appearance perspective view of the speed adjustment member used for the pachinko machine shown in FIG. It is a schematic cross section which shows a mode that the spherical channel | path shown in FIG. 2 was cut | disconnected by the orthogonal plane. It is the fragmentary sectional view which made the ball passage shown in Drawing 2 into a section partially seeing from the upper part.
