Description

  The present invention relates to a pachinko machine, and more particularly to a structure of a center decorative member provided in the pachinko machine.

  In a conventional pachinko machine, for example, as described in Patent Document 1, a center accessory (corresponding to a “center decoration member”) is arranged so as to surround a display screen arranged at the center position of the game area. In addition, a ball receiving shelf (corresponding to a “stage”) on which a pachinko ball from the warp device rolls is provided at the lower part of the center accessory. In addition, a game nail (corresponding to the “obstacle member”) is arranged in the game area around the center bonus, and a start winning opening (corresponding to the “winning prize”) is provided below the center bonus. Is arranged.

In addition, an inclined surface is formed at the upper left edge of the center accessory, and when a launch ball collides with the inclined surface, many pachinko balls roll down the left lateral outer side of the center accessory, Guided to the outside of the character.
JP 2005-13703 A

  However, in recent years, large-sized display screens have been arranged, so that a pachinko ball tumbles down in the game area located outside the upper left edge of the center object, and thus in the game area. There was a tendency for the possible rolling area to become narrow, and there were very severe restrictions on the layout of the game nail in consideration of the winning rate.

Specifically, as the size of the display screen increases, for example, 15 inches, the degree of freedom in the layout of the game nail decreases. When designing the layout of game nails for the purpose of decelerating pachinko balls to be played, or when designing the path of game nails for the purpose of guiding them toward the starting winning opening located under the center In addition, it is very difficult to adjust the winning rate.
In adjusting the winning rate, not only the layout of the game nail but also the inclination angle of the inclined surface formed substantially obliquely above the center accessory greatly affects. This is because, if the inclination angle is changed, the momentum of the launch ball that collides with the inclined surface changes, and the probability that the pachinko ball goes to the start winning opening while colliding with the game nail also changes.
In addition, in the path of the game nail for guiding to the starting port arranged on the lower outer side of the center role, if the pachinko ball jumps up too far from the stage, the winning rate is greatly affected.
These things make the restrictions on the layout more severe, such as the arrangement of game nails in consideration of the winning rate, as the size of the display screen becomes larger.
Therefore, in order to allow a relaxed design against layout constraints such as the placement of game nails, the pachinko ball flows down to the starting port by placing the area around the center object, that is, the game nails, etc. It is necessary to secure a sufficient space in the rolling region until it is finished.
From this point of view, if a part of the center object is overlaid on the display screen, the display screen will be partially hidden even though the display screen has been increased in size. Visual effects cannot be fully exhibited.

  In addition, if there is a need to install a movable object for decoration on one side of the center role and a need to provide multiple warp routes, the operation of the movable object for decoration will increase. In some cases, a warp route must be provided at a position outside the range, and the lateral width of the center role is further widened, and accordingly, the rolling region is further narrowed. Also, if the warp route is overlaid on the display screen so that the rolling area does not become even narrower, the display screen will be further hidden, so the effect of increasing the size of the display screen will be more fully achieved. I can't show it.

  Even if the size of the display screen is the same as in the past, for example, 13 inches, for example, a large accessory is provided in the rolling region on either the outside of the center accessory (left or right), for example. Or, when arranging decorative ornaments and many accessories, the center feature must be moved in the opposite direction to the placement side of the large feature along with the display screen, If the area becomes narrower, we are similarly concerned.

  Therefore, the present invention has been made in view of the above points, and makes it easy to adjust the jumping of the pachinko ball to the stage even if the display screen whose outer periphery is surrounded by the center decoration member is enlarged or unevenly distributed. That is, it is an object of the present invention to provide a pachinko machine having a structure that makes it easy to adjust the winning probability at the start winning opening and does not hinder the visual recognition of the display screen.

  In the pachinko machine of the invention according to claim 1 formed to solve this problem, a partition wall is provided that rises upward from the position of the lane of the stage. Therefore, the rolling area is guided by the guide rail. When the pachinko ball that has entered inside flows down around the center decoration member and is guided toward the start winning opening through the obstacle member positioned in the flow-down direction compared to the stage of the center decoration member, from the obstacle member The probability that the pachinko ball will jump up on the stage lane of the center decorative member can be adjusted with the partition wall. Therefore, the arrangement restrictions with respect to the obstruction member provided in the rolling region are eased.

  In addition, since the partition wall is formed of a transparent light-transmitting material, the display screen can be visually recognized through the partition wall even when the partition wall stands up forward so as to hide a part of the display screen. It becomes possible.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a front view showing a game board 202 of the pachinko machine according to the present embodiment. The board surface 202A of the game board 202 is provided with a substantially circular outer rail 206A and an inner rail 206B (corresponding to the “guide rail” in claim 1), and at the inner edges of the outer rail 206A and the inner rail 206B. A game area 207 is formed by the enclosed area.

Further, a hole (not shown) having a shape similar to the outer peripheral shape of the center decorative member 205 described later and slightly smaller than the outer peripheral size of the center decorative member 205 is provided near the center of the game area of the board surface 202A. It has been.
Although not shown, a liquid crystal type display device housed in a transparent case together with the display control board and unitized is fixed to a predetermined position on the back surface of the game board 202 with a screw or the like.
As a result, the display screen 203 of the display device is positioned behind a hole (not shown) formed near the center of the game area of the board surface 202A, so that the display screen 203 can be viewed from the front on the player side. It becomes possible.

On the other hand, on the surface (front) of the game board 202, as shown in FIG. 1, a part of the center decoration member 205 closes a part of a hole (not shown) formed near the center of the game area of the board surface 202A. The center decoration member 205 is fixed to the board surface 202A of the game board 202 so as to surround the vicinity of the outer periphery of the display screen 203 of the liquid crystal display device.
As a specific fixing method for the game board, the center decoration member 205 is fixed by inserting a screw into the screw hole 311A of the flange 311 while the flange 311 of the center decoration member 205 is in contact with the board surface 202A of the game board 202.

In the game area 207 formed on the board surface 202A of the game board 202, in addition to the center decoration member 205, a plurality of game nails 209, 210, and 213 are arranged, and a windmill 211, a first start port 214, and opening and closing A second starting port 215 having a tulip-shaped blade 215A, a gate 216, a prize winning port 217, an out port 218, an electrical decoration member 231A including LEDs, and the like are disposed.
Accordingly, in the game area 207 formed on the board surface 202A of the game board 202, the center decoration member 205 including the display screen 203, the first start port 214, the second start port 215, the big prize winning port 217, and the out port 218. A rolling region 232 in which the pachinko ball can roll down is formed in a region where the electric decoration member 231A is excluded.

  The game board 202 of this embodiment is attached to the pachinko machine 1 provided with the upper plate 219 or the lower plate 220, the handle 221 and the like as shown in FIG.

  Further, in the pachinko machine 1, when the player launches the pachinko balls collected on the upper plate 219 by operating the handle 221, the fired balls are rolled up along the rails 206A and 206B and released to the game area 207. Then, it falls and rolls while colliding and guided by the center decoration member 205, the game nails 209, 210, and 213, the windmill 211, the gate 216, the electric decoration member 231A, etc., and the first start port 214 and the second start port 215 , Winning a prize winning opening 217 or passing through an out opening 218. The pachinko machine 1 according to the present embodiment performs a lottery to determine whether or not the main control board (not shown) is a big hit when a pachinko ball wins the first start port 214 or the second start port 215. A known pachinko that performs display control so that a display designation based on the result is transmitted to a display control board (not shown) and the display control board (not shown) indicates a lottery result indicating whether or not the display screen 203 is a big hit. Machine.

Next, the center decoration member 205 will be described with reference to the drawings.
As shown in the front view of FIG. 1 and the perspective view of FIG. 3, the center decorative member 205 is provided with an opening 301 for exposing the display screen 203, and below the opening 301, A stage 305 is provided.
Further, two bent hollow cylindrical warp routes 302A and 302B are arranged on the left side of the opening 301 of the center decorative member 205.

  First, the stage 305 stands up so as to overlap the front side of the display screen 203, and a protection plate 312 that protects the display screen 203 from rolling pachinko balls, and a rib that stands at a position closer to the player than the protection plate 312. 306 and partition walls 310 and 313 are formed. A lane 307B is formed in a curved shape at the bottom between the protection plate 312 and the rib 306, and a lane 307A is formed in a curved shape between the partition walls 310, 313 and the rib 306. In the vicinity of the center of the lane 307A, the height of the lane 307B is such that a pachinko ball discharged from the outlet 304A of the warp route 302A described later is guided toward the drop entrance 308 provided near the center of the protective plate 312. It is formed higher above the position. The pachinko balls that have flowed down to the drop inlet 308 are configured to fall from the drop outlet 309 of the partition wall 313 toward the first start port 214 through an internal passage (not shown). Further, at a position shifted to the left and right from the vicinity of the center of the lane 307A, the pachinko sphere rolls from the lane 307B to the lane 307A and is inclined so as to flow from the lane 307A through the partition wall 313 to the rolling region 232. Has been.

  And the exit 304A, 304B of warp route 302A, 302B is each arrange | positioned at the left end side of each lane 307A, 307B.

The partition wall 310 is fixed to the center decorative member 205 with a screw or the like so as to protrude above the lanes 307A and 307B.
The projected height (height) and the horizontal size of the partition wall 310 are such that the fired pachinko ball is planted from the windmill 211 toward the first start port 214 in the rolling region 232 below the partition wall 310. The probability that the pachinko ball will flow down to the out port 218 without hitting the first start port 214 or the second start port 215 so as not to be overloaded on the stage 305 by hitting the game nail 213 provided and bounced back. , Or the probability that a pachinko ball will bounce off, be placed on the stage 305, and win the starting port 214 or the second starting port 215 is considered.

The partition wall 310 and the protective plate 312 are molded from a polycarbonate resin that is a colorless and transparent light-transmitting material.
Thus, the player can view the image displayed on the display screen 203 through the partition wall 310 or the protection plate 312. In addition, although a protection plate 312 is located behind a part of the partition wall 310, the player can view an image displayed on the display screen through the partition wall 310 and the protection plate 312.

  In addition, since the partition 310 is formed of a colorless and transparent light-transmitting material, even if the surface of the partition 310 is damaged by a pachinko ball, light is always emitted from the rear display screen 203 to the player side. As a result, scratches are less noticeable.

The partition wall 310 may be integrally molded as part of the center decorative member 205, and the partition wall 310 may be molded integrally with the partition wall 313.
In the present embodiment, the protective plate 312 is erected so as to overlap the front side of the display screen 203, so that the display screen 203 can be protected from the rolling pachinko balls and the rolling area can be secured as much as possible. In addition, an effect of effectively utilizing the enlarged display screen 203 can be obtained.

Further, the protection plate 312 may be configured as shown below.
A protection plate 312 shown in FIG. 11 is molded and processed with a polycarbonate resin, which is a colorless and transparent light-transmitting material, and is similar to the protection plate 312 in FIG.
The difference from the protective plate 312 of FIG. 3 is that convex portions 312A shaped like a cylinder cut in half are formed integrally with the protective plate main body 312B at four locations at intervals.
The convex portion 312A protrudes upward from the protection plate main body 312B and also protrudes to the player side.

In the pachinko machine 1 according to the present embodiment, when a plurality of pachinko balls win the first start port 214 or the second start port 215 within a predetermined time, the main control board (not shown) stores the start win and The number of start winnings (maximum 4) stored in the illustrated display control board is controlled to be displayed on the display screen 203 using a design such as a character.
That is, four convex portions 312A are provided so as to correspond to the display positions on the display screen 203 on which the design indicating the number of start winnings is displayed.
Since the convex portion 312A serves as a lens, it is formed so that the player can easily confirm the number of stored start prizes in order to enlarge the design displayed on the display screen 203.

Next, warp routes 302A and 302B formed on the left side of the opening 301 of the center decorative member 205 will be described.
The warp routes 302A and 302B have a hollow with an inner diameter slightly larger than the diameter of the pachinko sphere, and the respective inlets 303A and 303B (see FIG. 1) are formed on the left side edge of the center decorative member 205. Exits 304A and 304B are formed at the lower end. Further, the warp routes 302A and 302B are molded with polycarbonate resin which is a colorless and transparent light-transmitting material. Further, at least a portion standing up and down is a front side of the display screen 203 (FIG. 1). As shown in FIG. 1, when viewed from the front, a part of the portions erected on the upper and lower sides overlap each other.

  FIG. 4 is a partial cross-sectional view of the warp routes 302A and 302B and the display screen 203 taken along line AA in FIG.

  In the present embodiment, as shown in FIG. 4, when the display screen 203 is viewed from the player side, a part of the width (diameter) E1 of the warp route 302A and the width (diameter) E2 of the warp route 302B are partially By providing the portion E3 where the two overlap, the width E1 of the warp route 302A and the width E2 of the warp route 302B (E1 + E2) becomes narrower, so that the player does not go through the warp routes 302A and 302A. The display area in which the display screen 203 can be directly viewed increases.

  Although it is slightly harder to view than the image on the display screen 203 directly, the warp routes 302A and 302B are made of a polycarbonate resin, which is a colorless and transparent light-transmitting material, so that the warp routes 302A and 302B are passed through the warp routes 302A and 302B. The video on the display screen 203 can be visually recognized.

  When viewing the display screen 203 through the warp route 302A and 302B, the polycarbonate resin forming the warp route serves as a lens to refract the light, so that the image on the display screen 203 is most difficult to see in the region E3. However, it can be said that it is visually recognizable because the color and the like are areas that can be confirmed.

Thus, by arranging the warp routes 302A and 302B so as to partially overlap, as shown in FIG. 5, even if the pachinko balls P1 and P2 passing through the warp routes 302A and 302B overlap, A part of the pachinko sphere P2 passing through the warp route 302B can be confirmed.
Therefore, even if the pachinko spheres pass through the warp routes 302A and 302B at any timing, the passing pachinko spheres are not lost.

  Furthermore, in the AA location in FIG. 1, the entire width (E1 + E2-E3) of each warp route 302A, 302B is arranged on the front side of the display screen 203 so as to overlap the display screen 203. Despite the arrangement of the large-sized display screen 203, the width of the center decorative member 205 does not widen, and it becomes easy to secure a rolling area near the windmill 211.

  In this embodiment, the partition wall 310 is installed in front of the outlets 304A and 304B of the warp routes 302A and 302B. However, the partition wall 310 is also colorless and transparent and has light-transmitting properties, like the warp routes 302A and 302B. Since the molding process is performed with the polycarbonate resin, the player can check the pachinko balls discharged from the outlets 304A and 304B of the warp routes 302A and 302B through the partition wall 310, and further behind the pachinko balls. An image displayed on the display screen 203 can be viewed through the partition wall 310 and the warp routes 302A and 302B.

In the present embodiment, even if the display screen 203 is enlarged or unevenly distributed, the partition 310, the protective plate 312 and the warp route 305 are transparent light-transmitting materials. Since the display screen 203 can be visually recognized, a visual effect and the like can be sufficiently exhibited. Furthermore, as the display screen 203 increases in size, the rolling region 232 does not have to be narrowed so as to follow. Therefore, the winning rate of the ball with respect to the first start port 214 or the second start port 215 can be adjusted. Restrictions on the layout design in consideration can be made relatively lenient.
The cross sections of the warp routes 302A and 302B may have any shape such as an ellipse or a polygon as long as the pachinko sphere can pass through. For example, the cross sections of the warp routes 302A and 302B may be elliptical as shown in FIG. 6, and the cross sections of the warp routes 302A and 302B may be quadrangular as shown in FIG.

  As shown in FIG. 7 and FIG. 9 in which the warp routes 302A and 302B are arranged side by side as shown in FIG. 6 and FIG. The display area where the user can directly view the image increases.

In addition, it is not limited to said embodiment, A various change is possible in the range which does not deviate from the meaning.
For example, the number of warp roots may be three or more, and may be made of a colored transparent material.

Also, various changes can be made to the installation and shape of the warp route with respect to the center decorative member, and various changes can also be made to the shape of the center decorative member.
In the embodiment shown in FIG. 1, the warp routes 302A and 302B are formed of a transparent light-transmitting material, so that the display screen 203 on the rear side can be visually recognized through the warp routes 302A and 302B. Since the vicinity of the upper left corner of the display screen 203 located near the upper part of the routes 302A and 302B is located on the back surface of the game board surface 202A, it cannot be visually recognized from the player side.

For this reason, as another embodiment, if the following center decoration member is used, the display screen can be further visually recognized.
FIG. 10 is a front view of a game board configured as another embodiment.
When the configuration in FIG. 10 is described, the same reference numerals are used for the configurations common to the embodiment shown in FIG.

In FIG. 10, as a part of the center decorative member 205, a base single surface 401 </ b> A is formed as a new configuration. The base one surface 401A has a shape similar to the outline of a hole (not shown) opened in the center of the game board 202, and is slightly larger than the hole. Thus, only the peripheral edge portion of the base one surface 401A is fixed to the game board 202A with screws or the like in a state where it is in contact with the surface side of the board surface 202A.
A protruding single surface 402 is integrally formed on the base single surface 401A so as to stand vertically to the player side.
On the downstream side of the projecting piece surface 402, similarly to the projecting piece surface 402, an inclined piece surface 403 is integrally formed so as to rise vertically to the player side with respect to the base piece surface 401A.

The inclined single side 403 is generally the length from the upper left side to the lower side of the display screen 203, and constitutes the warp route 302C.
That is, the warp route 302C is formed of a hollow cylinder so as to receive a pachinko ball from an inlet 303C formed at the upper side and discharge the pachinko ball from an outlet 303D formed at a lower side. Thus, it is formed so as to be bent once toward the display screen side and extend downward again.

And slightly below the point P, a warp route 302A is formed in front of the warp route 302C.
These warp routes 302A and 302C are both made of a colorless and transparent light-transmitting material.
Therefore, the display screen 203 can be visually recognized from the player side via the warp routes 302A and 302C.

In the present embodiment, a part of the base one surface 401A is also made of a colorless and transparent light-transmitting material.
Specifically, the base one surface 401A is formed of a polycarbonate resin, which is a colorless and transparent light-transmitting material, with a region overlapping the display screen 203 at the upper left corner of the display screen 203 indicated by a two-dot chain line, Others are colored and opaque, and are integrally molded in two colors.
Therefore, a portion molded with colored resin in the base one surface 401A closes a hole (not shown) formed in the center of the game board 202, and is colored and opaque. The player cannot see the side.
On the other hand, even if the display screen 203 becomes large due to the portion made of a colorless and transparent light-transmitting material in the base one side 401A, the player can visually recognize it.

  Note that the base one surface 401A of the present embodiment also functions as a rolling region of the board surface 202A. For example, it is more preferable that the pin shape or the obstacle wall is formed integrally with the base piece surface 401A so as to protrude from the base piece surface 401A to the player side.

  In the present embodiment, the base one surface 401A located in the vicinity of the upper left corner of the display screen 203 is integrally molded in two colors with polycarbonate, which is a transparent light-transmitting material, and a colored resin. The player can visually recognize only the display screen through the resin. However, if the display screen 203 is configured in the same manner in the vicinity of the lower left corner, the upper right corner, or the upper right corner, the game board 202 can be further configured. It is possible to increase the viewing area of the display screen 203 in a state where a hole (not shown) opened in the center is hidden.

  That is, even if the display screen 203 is enlarged or unevenly distributed, the base single side 401A, the warp route 305, and the like of the center decorative member 205 are transparent light-transmitting materials. Can be visually recognized, so that the visual effect and the like can be sufficiently exhibited. Furthermore, as the display screen 203 increases in size, the rolling region 232 does not have to be narrowed so as to follow. Therefore, the winning rate of the ball with respect to the first start port 214 or the second start port 215 can be adjusted. Restrictions on the layout design in consideration can be made relatively lenient.

  From the above, the present invention makes it easy to adjust the jumping of the pachinko ball to the stage even if the display screen surrounded by the center decoration member is enlarged or unevenly distributed, that is, winning the starting prize opening It is possible to provide a pachinko machine having a structure that facilitates adjustment of the probability and does not hinder the visual recognition of the display screen.
