Description

  The present invention relates to a game ball guiding member that is arranged on a game board of a game machine such as a pachinko machine and is sometimes called a croon.

  2. Description of the Related Art Conventionally, a ball receiving region having a dish shape or a mortar shape as a whole is formed on a croon (game ball guiding member) arranged on a game board. A sphere discharge hole is formed through the lower portion of the sphere receiving area, and an inclined portion is formed which is inclined in a form in which the diameter is reduced from the upper opening toward the lower sphere discharge hole (a form in which the diameter is increased toward the upper opening side). Has been. Therefore, the game ball introduced from the upper opening and rolling on the inner surface of the inclined portion flows down while circulating around the ball receiving area (inclined portion) and is led out from the lower ball discharge hole.

  When there are a plurality of ball discharge holes in such a croon, any one of the ball discharge holes shares the axis with the entire ball receiving area (or inclined portion), or all the ball discharge holes have the axis of the entire ball receiving area. Regardless of whether or not they have an offset (齟齬; deviated) axis, they are usually used for winning devices (distribution devices) in which all ball discharge holes are assigned hit / off. On the other hand, when there is a single ball discharge hole, the ball discharge hole is generally used for a relay device or the like that has nothing to do with the result. However, for example, if a sorting rotator is arranged below a ball receiving area that shares an axis with the ball discharge hole, the croon constitutes a part of the winning device (sorting device).

  The inner surface contour line of the conventional ball receiving area (inclined portion) is composed (drawn) with the same curvature (curvature radius), for example, so that the movement of the game ball on the ball receiving area is simplified. There was little diversity. Therefore, regardless of whether the Kroon is used as a winning device (distribution device) or a relay device, the end of the game (whether it is a success or failure or the route of the game ball or the flow route) can be predicted from the movement of the game ball on the ball receiving area. There was a risk that the interest of the player would be offended. In addition, when the Kroon constitutes at least a part of the winning device (distribution device), the game ball is moved to a specific ball by a fraudulent act such as hitting the glass frame of the gaming machine and vibrating the Kroon at the timing. There was a possibility that it could be led out from the discharge hole or dropped into a specific area of the rotating distribution body.

  An object of the present invention is to provide a game ball guiding member that can give a surprising interest to a movement of a game ball that circulates and flows down in a ball receiving area, and that is useful for preventing cheating. There is.

Means for Solving the Problems and Effects of the Invention

In order to solve the above problems, the game ball guiding member of the present invention is
The ball receiving area having a dish-like or mortar-like shape as a whole has a ball discharge hole formed so as to have an axis that is offset from the axis of the entire ball receiving area and / or a shared axis, and the upper opening side expands. In a game ball guiding member that includes a slanted portion that is slanted in a form to be radiated and flows down while circulating a game ball that is introduced from the opening and rolls on an inner surface of the slanted portion, and is led out from the ball discharge hole,
In the inclined portion of the ball receiving area, a direction in which the game ball circulates and flows down is located above the ball discharge hole and by partially changing the inclination of the inner surface along the radial direction and / or the circumferential direction. In addition, an inclination changing portion for changing the speed and causing a change in the relative positional relationship between the ball discharge hole and the game ball is formed.

In order to solve the above-mentioned problem, the game ball guiding member of the present invention is, for example,
A ball receiving region having a dish-like or mortar shape as a whole is sandwiched between a plurality of ball discharge holes each formed in a form having an axis that is offset from the axis of the entire ball receiving region, and the ball discharge holes. A bottom portion and an annular inclined portion that is inclined in such a manner that the diameter of the upper opening side is increased toward the upper opening side, and the game ball that is introduced from the opening and rolls on the inner surface of the inclined portion is caused to flow down while circulating. In the game ball guiding member to be derived from any of the plurality of ball discharge holes,
The inclined portion of the ball receiving area is positioned above the plurality of ball discharge holes, and the game balls are circulated and flowed down by partially changing the inclination of the inner surface along the radial direction and / or the circumferential direction. An inclination changing part is formed for changing the direction and / or speed of the ball and changing the relative positional relationship between the ball discharge hole and the game ball.

  According to these game ball guiding members, the movement (direction and / or speed change) of the game ball that circulates and flows down the ball receiving area can not be predicted by the inclination changing part formed in the inclined part of the ball receiving area. It is possible to impart sex and increase interest in games regardless of the proficiency level of the player. In addition, when used as a winning device (distribution device) in which a plurality of ball discharge holes are formed in a form having an offset (frozen) axis, the ball receiving area does not use magnetic force or the like. It is also possible to prevent fraud by a simple configuration in which the slope changing portion is simply provided on the slope portion. In addition, you may provide an inclination change part in any aspect (form) of only the radial direction of the inclination part, only the circumferential direction, radial direction, and the circumferential direction.

  Specifically, the inclination changing portion is formed in a ring belt shape having a predetermined width in the inclined portion with the axis of the entire ball receiving area as a center, and the game ball that is introduced from the opening and circulates and flows down the ball receiving area, The direction and / or speed of the circulation / flow down to that time is changed by the inclination changing unit, and is derived from the ball discharge hole. In this way, by the inclination changing portion formed in the ring belt shape, a sudden change in direction and / or speed can be clearly given to the appearance in the course of circulation or flow of the game ball.

  At that time, if the width W of the ring belt-shaped inclination changing portion formed in the inclined portion of the ball receiving area is set to 0.1D ≦ W ≦ 2.0D, where D is the diameter of the game ball, It is possible to make the player visually recognize a rapid change in direction and / or speed in the course of circulation or flow of the ball. In addition, when the width W of the inclination change part is less than 0.1D, there is a possibility that the amount of change in direction and speed becomes small and it is difficult to confirm. On the other hand, when the width W of the inclination changing portion is more than 2.0D, the game ball guiding member may be increased in size.

And in the cross section including the axis of the entire ball receiving area,
(1) changing the taper of the inner surface contour line;
(2) changing the curvature of the inner surface contour line;
(3) forming a step in the inner surface contour line;
(4) An inflection point is included in the inner surface contour line;
The inclination changing unit can be configured by at least one selected from the above. For example, since these forms (modes) are added to the inner surface contour line and the game ball guiding member can be integrally formed by injection molding or the like, it can be manufactured at a low cost with a simple structure.

  Of course, the inclination changing unit may be configured by combining the forms (1) to (4). Moreover, it is good also considering the substantially whole surface of an inclination part as an inclination change part, and it is good also considering a part of inclination part as an inclination change part. By these, an inclination change part can be made into the form which was rich in variety. For example, with respect to the inflection point of (4), the inflection point of the first form that changes from the outwardly convex form to the inwardly convex form, and the second form that changes from the inwardly convex form to the outwardly convex form Any of the inflection points may be used, and the inflection points of the first form and the second form may be used repeatedly.

Therefore, in order to solve the above problems, the first specific embodiment of the game ball guiding member of the present invention is:
The ball receiving area having a dish-like or mortar-like shape as a whole has a ball discharge hole formed so as to have an axis that is offset from the axis of the entire ball receiving area and / or a shared axis, and the upper opening side expands. In a game ball guiding member that includes a slanted portion that is slanted in a form to be radiated and flows down while circulating a game ball that is introduced from the opening and rolls on an inner surface of the slanted portion, and is led out from the ball discharge hole,
The inclined portion of the ball receiving area is positioned above the ball discharge hole, and the direction and / or speed at which the game ball circulates and flows down by partially changing the inclination of the inner surface along the radial direction. An inclination changing part is formed for changing and causing a change in the relative positional relationship between the ball discharge hole and the game ball,
In the cross section including the axis of the entire ball receiving area, the inner surface contour line of the inclination changing portion changes from a radially outwardly convex shape on the opening side to a radially inwardly convex shape on the spherical discharge side. Inflection points are included.

In order to solve the above-mentioned problem, the second specific embodiment of the game ball guiding member of the present invention is:
The ball receiving area having a dish-like or mortar-like shape as a whole has a ball discharge hole formed so as to have an axis that is offset from the axis of the entire ball receiving area and / or a shared axis, and the upper opening side expands. In a game ball guiding member that includes a slanted portion that is slanted in a form to be radiated and flows down while circulating a game ball that is introduced from the opening and rolls on an inner surface of the slanted portion, and is led out from the ball discharge hole,
The inclined portion of the ball receiving area is positioned above the ball discharge hole, and the direction and / or speed at which the game ball circulates and flows down by partially changing the inclination of the inner surface along the radial direction. An inclination changing part is formed for changing and causing a change in the relative positional relationship between the ball discharge hole and the game ball,
In the cross section including the axis of the entire ball receiving area, the inner surface contour line of the inclination changing portion changes from a radially outwardly convex shape on the opening side to a radially inwardly convex shape on the spherical discharge side. A first inflection point that is located below the first inflection point, and changes from a convex shape radially inward on the opening side to a convex shape radially outward on the ball discharge hole side. And a second inflection point.

  According to these game ball guiding members, since the inflection point is included in the inner surface contour line of the inclination changing portion, the radial direction in the inclination changing portion or The dimensional change ratio in the axial direction (vertical direction) can be increased. Therefore, a sudden change in direction and / or speed can be easily imparted to the game ball that is circulating or flowing in the ball receiving area.

  In these game ball guiding members, in the cross section including the axis line of the entire ball receiving area, the inner surface contour line of the inclination changing portion can include a curvature changing point where the curvature changes without changing the convex shape. . As described above, since the inner surface contour line includes the curvature change point in addition to the inflection point, a further unexpected motion (change in direction and / or speed) is given to the game ball that circulates and flows down the ball receiving area. be able to. In the second specific embodiment of the game ball guiding member, the curvature change point can be positioned between the first and second inflection points.

As shown in FIG. 1 and FIG. 2, the croon 1 includes a ball receiving region 5 that is located below the annular upper wall portion 2 (circumferential wall portion) and has a dish shape or a mortar shape as a whole. A plurality of (for example, three) ball discharge holes 5a each penetrating in a form having an entire axis O1 (see FIG. 3) and an offset (fluttered; deviated) axis O2 (see FIG. 3); The bottom wall portion 3 (bottom portion) sandwiched between the sphere discharge holes 5a (that is, including or including a plurality of sphere discharge holes 5a), and the diameter of the bottom wall portion 3 is increased toward the upper opening 2a side. It is configured to include an inclined annular inclined wall portion 4 (inclined portion).

  Specifically, the croon 1 has an annular upper wall portion 2 that opens upward and extends in the vertical direction at a high position, and a plurality (for example, three) of ball discharge holes 5a are formed so as to penetrate in the horizontal direction at a low position. It has a bottom wall portion 3 that extends, and an annular inclined wall portion 4 that is positioned between the upper wall portion 2 and the bottom wall portion 3 and is inclined in such a manner that the diameter is reduced toward the lower position side. Then, the game ball B introduced from the opening 2a through the upper wall portion 2 and rolling on the inner surface of the inclined wall portion 4 flows down while circulating around the ball receiving area 5, and any one of the three ball discharge holes 5a. Is derived from As described above, the ball receiving region 5 that allows the rolling game ball B to flow down while circulating is mainly formed by the inclined wall portion 4 and the bottom wall portion 3. Reference numeral 7 denotes a guide projection which is provided at the center of the bottom wall portion 3 and has a surface facing each ball discharge hole 5a, and guides the game ball B on the bottom wall portion 3 to any one of the ball discharge holes 5a. Discharge. Reference numeral 8 denotes an annular seating portion formed on the outer surface of the ball receiving area 5 for mounting and fixing on a mounting surface such as a base plate or a base frame.

  As shown in FIG. 3, the inclined wall portion 4 of the ball receiving area 5 changes the direction and speed in which the game ball B circulates and flows down by partially changing the inclination of the inner surface along the radial direction. An inclination changing unit 6 for changing the relative positional relationship between the discharge hole 5a and the game ball B is configured. That is, the inclination changing portion 6 is located above the ball discharge hole 5a and has a predetermined width (for example, an inclined wall portion) within the inclined wall portion 4 with the axis O1 of the inclined wall portion 4 (the entire ball receiving region 5) as the center. 4 is formed in a ring belt shape having a width W equal to 4.

  As shown in an enlarged view in FIG. 4, in the cross section including the axis O <b> 1 of the inclined wall portion 4 (the entire ball receiving region 5), the inner surface contour line of the inclined changing portion 6 protrudes radially outward on the opening 2 a side. The first inflection point P1 is included which changes from the above shape into a convex shape radially inward on the sphere discharge hole 5a side. Further, a second inflection located below the first inflection point P1 and changing from a radially convex shape on the opening 2a side to a radially convex shape on the spherical discharge hole 5a side. Point P2 is included. The bottom wall portion 3 below the second inflection point P2 is formed in a tapered shape (linear shape; the radius of curvature is infinite).

  Further, the inner surface contour line of the inclination changing portion 6 includes a curvature change point Q that is located between the first and second inflection points P1 and P2 and the curvature changes without changing the convex shape. It is.

At this time, when the radius of curvature r1 is infinite, the portion between P1 and Q is tapered (straight).

  Thus, when the first and second inflection points P1 and P2 are included in the inner surface contour line of the inclination changing portion 6, the inclination changing portion 6 The ratio of dimensional change in the radial direction can be increased. Further, when the curvature radius r1 is set to be larger than the curvature radius r2, the height between the first inflection point P1 and the curvature change point Q is higher than the height in the vertical direction of the croon 1. Thus, the dimensional change ratio in the radial direction at the inclination changing portion 6 is increased, and between the curvature changing point Q and the second inflection point P2, the inclination changing portion 6 is compared with the diameter of the croon 1 at the inclination changing portion 6. The dimensional change rate in the axial direction (vertical direction) increases. By the inclination changing unit 6, the direction and speed of the game ball B that has been orbiting / flowing down in the ball receiving area 5 are changed in the direction and speed of the game ball B until then, and an unexpected movement (abrupt change in direction and speed) is given. Then, it is led out (discharged) to one of the ball discharge holes 5a.

  In FIG. 2, CP1 is a connecting circle in which the first inflection point P1 is connected in the circumferential direction, CP2 is a connecting circle in which the second inflection point P2 is connected in the circumferential direction, and CQ is around the curvature changing point Q. Each of the connected circles connected in the direction is shown.

  Returning to FIG. 3, the width W of the ring belt-shaped inclination changing portion 6 formed in the inclined wall portion 4 of the ball receiving area 5 is 1.0D ≦ W ≦ 1. It is set to 5D (for example, W = 1.2D). As a result, a sudden change in direction and speed is imparted to the game ball B during its circulation or flow, so that the unexpected movement of the game ball B can be clearly seen by the player.
