Description

  The present invention comprises an image display and a light-transmitting game board main body arranged to face the display surface side of the image display, and the game balls flow down along the game board main body surface. The present invention relates to a gaming machine provided with a game board unit that allows a game to progress while being played.

  Conventionally, a so-called full-screen pachinko machine having a large display has been proposed (see Patent Document 1). This full-surface display pachinko machine has a transparent member constituting the game board, and the back side of the transparent game board has almost the same external shape as the game board, or smaller than that (the diagonal dimension of the display screen is from 15 inches). By displaying a display of about 20 inches, when viewed from a player who is playing a game, the entire game board becomes a display screen, and a pachinko ball is overlapped with a plurality of game nails and windmills. It falls while bouncing back.

  In a pachinko machine equipped with such a large display, the scale of the effect display is larger than that of the conventional type (the diagonal size of the display screen is about several inches to 12 inches), and a further effect can be expected. . When the screen becomes larger, not only the pattern variation pattern but also the background image is enlarged.

  According to this Patent Document 1, a transparent game board is provided on the front surface of the liquid crystal display device, so that a game ball can pass between the game board and the liquid crystal display device through a general winning member. A prize opening opening / closing member that restricts the inflow to the general prize-winning member is provided, and a visual change is also given to the game ball itself by controlling whether or not the game ball can flow in.

  Here, in the above-described full-screen pachinko machine, it has been proposed to cause a change in the viewing area (display frame) of the display screen between the player and the display surface, that is, the game board (Patent Document 2 and Patent Document 3). reference).

Patent Document 2 discloses that the display size of a symbol is changed in accordance with the degree of reliability. Further, Patent Document 3 discloses that the display area of a symbol changes according to the hit reliability.
JP-A-2005-131300 JP 2002-315907 A JP 2004-49635 A

  However, in the gaming machines described in Patent Document 1 to Patent Document 3, for example, when the obstacle nail is driven into the game board (transparent), the obstacle nail is driven while maintaining a predetermined interval with respect to the two-layer game board. Despite the necessity of special and advanced technology for this purpose, there is no description about this point, it is not described to the extent that can be easily implemented by those skilled in the art, and the reality of the product is poor.

  In consideration of the above facts, the present invention establishes a transparent game board body structure that can reliably hold obstructions, winning holes, etc. essential to the game board body, and is possible only because it is a transparent game board body. It is an object of the present invention to obtain a gaming machine capable of improving the game performance by setting the flow down area.

  The invention described in claim 1 is composed of an image display, and a light-transmitting game board main body arranged facing the display surface side of the image display, along the surface of the game board main body. A gaming machine including a game board unit that advances the game while flowing down the game ball, wherein at least two flow-down areas for flowing down the game ball are provided, and the game board body includes the flow-down area. A through-hole through which game balls can go to and from each other is provided, and in the flow-down area, an obstacle that restricts and guides the flow of the game ball, and the game ball can win and change the progress of the game At least one of the winning openings is appropriately arranged in a state of being held by the game board main body.

  According to the first aspect of the present invention, the visual effect of a game ball flowing down two or more falling areas of a light-transmitting gaming board main body (for example, a glass plate or an acrylic plate having a transmittance of almost 100%). And the virtual visual effect displayed on the image display device can produce a synergistic effect, and the visual performance for the player can be increased.

  In addition, the frequency of guiding the game ball to the through hole can be adjusted according to the model according to the design and adjustment of the obstacles and winning holes, so that the game ball is distributed between at least two flow-down areas. In contrast, a visual game change is imparted in a manner of game ball flow for each model.

  Furthermore, since at least two flow areas are provided, the number of obstacles and winning openings can be dramatically increased, and the guide load on the flow path of the game ball is simply reduced per obstacle, It is possible to reduce both adjustments related to the flow path per obstacle and reduce friction coefficient incompatibility (for example, metal nails and acrylic resin game boards), facilitating sales pitch adjustment. .

  In addition, since the obstacle and the winning opening are securely held by the game board main body, the flow direction of the game ball becomes an unexpected direction, and the game performance can be further increased.

  According to a second aspect of the present invention, in the first aspect of the present invention, two or more game board main bodies are disposed, and are spaced apart from each other by a predetermined dimension based on the game ball diameter. Each of the surface sides of the game board main bodies directed to the players is the flow-down area.

  According to invention of Claim 2, since each game board main body can be manufactured by the operation | work by the same process as driving the obstruction nail as an obstruction into the existing plywood board, improvement of capital investment, production technology, etc. is carried out. It becomes unnecessary.

  According to a third aspect of the present invention, in the first aspect of the present invention, the game board main body is disposed at an interval of a predetermined dimension based on the game ball diameter with respect to the image display. Each of the front and back sides of the game board main body is the flow-down area.

  According to the third aspect of the present invention, since two different flow-down areas can be provided by a single game board main body, the number of parts can be reduced.

  According to a fourth aspect of the present invention, in the first aspect of the present invention, the game board body maintains a predetermined pressure by closely contacting the pair of light transmissive members and the pair of light transmissive members. A contact-type game board main body constituted by a pressurizing frame that is held in this manner, and the contact-type game board main body has a predetermined dimension based on the game ball diameter with respect to the image display. It is arranged at intervals, and each of the front and back sides of the close-contact game board main body is defined as the flow-down area.

  According to the invention described in claim 4, since each game board body can be manufactured by the same process as driving an obstacle peg as an obstacle into an existing plywood board, improvement in equipment investment, production technology, etc. It becomes unnecessary.

  According to a fifth aspect of the present invention, in the invention of the fourth aspect, the refractive index of the light transmissive member is less than the refractive index of the air between the pair of light transmissive members in close contact. Is also characterized by interposing a solvent on the near side.

  According to the invention described in claim 5, the most common glass or acrylic plate as the material of the game board main body having optical transparency has a refractive index of 1.5 to 1.8. If this is simply brought into close contact, an air layer is formed between them. Since the refractive index of air is 1.0, the deviation of the reflected image on the front and back surfaces and the interface of the game board main body to be brought into contact is significant due to the difference in refractive index. Therefore, a solvent such as water is interposed. For example, since the refractive index of water is about 1.3, the difference in refractive index can be reduced, and even if there is heavy reflection, it is difficult to understand (there is little deviation).

  Furthermore, by interposing a solvent, the unevenness of the contact surface is eliminated, leading to improved adhesion.

  The invention according to claim 6 is the invention according to any one of claims 1 to 5, wherein a part of the game board main body is fitted into the game board main body as the obstacle. The other part is provided with a rod-like body projecting into the flow-down region.

  According to the invention described in claim 6, for example, as in the case of claim 3 or claim 5, when a bar-like body as an obstacle is provided on the front and back surfaces as a result, the game board main body is penetrated, and if necessary Thus, by ensuring the length to project in the penetrating direction, it is possible to simply configure the flow-down regions having obstacles with different arrangements.

  According to a seventh aspect of the present invention, in the invention according to any one of the first to sixth aspects, the game board main body has a fitting portion outer diameter corresponding to the bar-like body, and A through hole having an inner diameter with a predetermined dimensional tolerance is provided in advance.

  According to the seventh aspect of the present invention, for example, when the obstacle nail is driven into the plywood plate, it is not necessary to provide a preliminary hole due to the material characteristic of the plywood plate. Depending on the material, there is a possibility of cracking due to driving. Therefore, the game board main body is previously provided with a through-hole that has an outer diameter of the insertion portion of the rod-shaped body and an inner diameter of a predetermined dimensional tolerance. Thereby, generation | occurrence | production of the crack resulting from driving-in of a rod-shaped body etc. can be avoided.

  As described above, the present invention establishes a transparent game board body structure that can reliably hold obstructions, winning holes, etc. essential to the game board body, and is possible only because it is a transparent game board body. Setting the flow-down area has an excellent effect that the gameability can be improved.

“First Embodiment”
(Configuration of pachinko machine)
As shown in FIGS. 1 and 2, a lower decoration 12 serving as a decorative panel is attached to the lower front portion of the pachinko machine 10.

  Further, a glass frame 16 fitted with a glass plate 14 is arranged on the upper part of the undergarment 12 of the pachinko machine 10, and the glass frame 16 is attached so that it can be opened and closed with its left end portion pivotally supported. On the back side of the glass frame 16, a game board unit 18 that is provided with a rectangular opening and that can be replaced is set. The game board unit 18 closes the glass frame 16 in a closed state. 14 to face.

  Around the glass plate 14 in the glass frame 16, an indicator lamp 20 for lighting effect is generated to produce an effect effect by lighting by turning on, turning off and flashing according to the progress of the game. Speakers 22L and 22R for outputting sound effects in stereo are arranged.

  An integrated dish 24 is disposed below the glass frame 26. A firing handle 26 for adjusting the firing force (flying distance) of the hit ball is attached to the lower right portion of the integrated dish 24.

(Composition of game board unit)
As shown in FIGS. 3 to 5, the game board unit 18 includes a pair of game board main bodies in which a celluloid sheet (not shown) is partially attached to an acrylic board having a light transmittance of almost 100% as necessary. 52F and 52R and a liquid crystal display (LCD) 54 are provided.

  The LCD 54 is disposed on the back side of the game board main body 52R on the back side when viewed from the players of the pair of game board main bodies 52F and 52R, and on the front side of each of the pair of game board main bodies 52F and 52R. It has a display area of almost the same area as the flow area of a game ball.

  Obstacles that guide the flow of game balls such as nails 55 and windmills 56 and bounce them back in unexpected directions on the surface side (opposite surface side) when viewed from the players of the game board main bodies 52F and 52R , An accessory unit that triggers a prize by winning a game ball or changes the game state (in the first embodiment, the upper and lower parts of the game board main body 52F have a nailed accessory unit 58A, A lottery accessory unit 58B) is provided. Note that the accessory unit is only the front game board main body 52 </ b> F, and is arranged in a non-opposing portion with the LCD 54, thereby also serving as a shielding member. In addition, a rail 60 for guiding the launched game ball onto the game board surface is attached to the front game board main body 52F.

  In the game board main body 52F, a horizontally long region is transmitted through the front view by the ceiling nail accessory unit 58A and the lottery accessory unit 58B (substantially the same as the angle of view of the LCD 54).

  A ceiling nail 55A is insert-molded in advance in the ceiling nail accessory unit 58A, and a through hole 60 is provided corresponding to the ceiling nail 55A.

  As shown in FIG. 4, the through hole 60 is coaxial with the through hole 62 provided in the game board main body 52F in advance, and guides the game balls related to the ceiling nails 55A to the through holes 60 and 62, and the front surface It is possible to guide from the flow down area 52Farea of the game board main body 52F on the side to the flow down area 52Rarea of the game board main body 52R on the back side.

  In addition, a through hole 64 whose inclination direction is reversed from that of the through hole 62 is formed in the lower part of the game board main body 52F (slightly above the lottery combination unit 58B). The through hole 64 serves to guide the game ball in the flow down area 52Rarea of the game board main body 52R to the flow down area 52Farea of the game board main body 52F.

  Further, as shown in FIGS. 3 and 4, the lottery accessory unit 58B is opened when a winning prize winning port 66 is internally used as a trigger for a special symbol lottery by winning, and the lottery result is a big win. The attacker 68 collects the game ball that has reached the lowest position of the game board main body 52F, the passing port 72 that triggers the normal symbol lottery that opens the electric tulip 70 attached to the start winning port 66 when the game ball passes. An out port 74 is provided.

  The lottery accessory unit 58B requires, for example, a drive source for performing an opening / closing operation of the attacker 68, a sensor for detecting a winning or passed game ball, and the like from the back side of the game board main body 52F. It is accommodated in an I / O box 76 that protrudes to the back side of the panel body 52R. A guide path for guiding the game ball is also formed in the I / O box 76 to guide the game ball in a predetermined direction.

  Here, as an example of the game specification, when a game ball is effectively won at the start winning opening 66, an internal lottery is executed. The term “effective winning” refers to excluding the case where the number exceeding the limit when consecutive winnings are not subject to the internal lottery, so that it is not subject to the internal lottery.

  The result of the lottery is notified by a symbol variation pattern effect using the LCD 54.

  This symbol variation pattern effect generally performs symbol variation in three columns, and when all the columns stop in the same symbol finally, it is won, otherwise it is lost.

  In the game board main body 52F, there are basically no obstacles such as nails 55, windmills 56, etc. in the predetermined area in the center so that this symbol variation pattern effect can be visually recognized. It is configured to be surely visible through a certain game board main body 52F, 52R.

  When the result of the lottery is a big hit, the attacker 68 performs a predetermined round opening / closing operation. The opening time of one round is about 30 seconds or the winning of 10 game balls, whichever comes first. As a result, the player can acquire a large number of game balls in a short period of time using the prize balls.

  In the above game specifications, winning in the start winning opening 66 is an opportunity. Therefore, for example, in the top nail accessory unit 58A of the game board main body 52F, the game ball is guided to the flow-down area 52Rarea of the game board main body 52R through the through holes 60 and 62, and the through hole 64 is formed. It is also possible to set the arrangement of the nails 55 and the like so that the route to be returned through can easily win the start winning opening 66.

  Since this is different from the general aim of the left-handed start winning opening 66, it is necessary to adjust the target (launch strength), which leads to an improvement in game preference.

  As described above, the nail 55 may be so-called insert-molded when the top nail accessory unit 58A is manufactured, or may be directly driven into the game board main bodies 52F and 52R.

  In this direct driving, since the conventional game board is a plywood board, there is no need for a pilot hole or the like. However, since the game board main bodies 52F and 52R of the first embodiment are transparent acrylic boards, direct nails are used. When 55 is driven, a crack may occur from this driving point (the same applies to the windmill 56).

  Therefore, pilot holes 78 (see FIG. 5) are formed in the game board main bodies 52F and 52R in advance at positions where the nails 55 are driven.

  As shown in FIG. 5, the outer diameter φa of the driving portion of the nail 55 is larger than the inner diameter φb of the pilot hole 78 provided in the game board main bodies 52F and 52R (φa> φb). As actual dimensions, φa is 1.85 mm and φb is 1.75 to 1.80 mm, and these relationships are obtained from predetermined fitting tolerances. As a result, when the nail 55 is applied to the pilot hole 78 and inserted (press-fitted) with a predetermined pressure, the nail 55 can be fitted into the pilot hole 78 (fitting).

  The operation of the first embodiment will be described below.

(Game flow of pachinko machine 10)
In the game using the pachinko machine 10, when the player operates the launch handle 26, the game balls stored in the integrated dish 24 are supplied to the launch device one by one by the ball feeding device, and are launched upward by the launch device. The launched game ball hits a nail driven into the game board main body 52F (or 52R) and falls while changing its direction. Then, the game balls that have reached the lower end without winning are collected from the out port 74 to a predetermined location in the pachinko machine 10.

  When the game ball wins the start winning opening 66, a lottery process is executed, and the lottery result is notified on the LCD 54 as a symbol variation pattern effect. If the winning is made by this notification, the jackpot processing is executed.

  In the jackpot process, the attacker 68 provided in the game board main body 52F is released a predetermined number of times (round) for a predetermined time. In general, the opening time of one round is about 30 seconds, and during this period, up to 10 game balls are won, or 30 seconds have passed, either of which is satisfied first, the round ends and the next round Migrate to Since this is continued about 14 rounds (15 rounds in total), in the jackpot processing, a large number of winnings are expected in a short period of time, and a gaming state advantageous to the player can be achieved.

  Pachinko machines having such game specifications have been conventionally executed in various forms, and display effects by the LCD 54 have been mainstream as means for increasing the variations.

  In the first embodiment, expansion of the display effect by the LCD 54 is realized by using the large LCD 54, and two transparent game board main bodies 52F and 52R are applied as the configuration of the game board. .

  The greatest feature of the expansion of the effect produced by the application of the large LCD 54 is that the game area and the display area overlap in the player's field of view, so that a sense of depth is produced, and the video is executed in almost all of the game area. Therefore, there is a sense of realism. In addition, it is possible to change the size of the design by the design variation pattern production from small to large (zoom function). For example, the notification image that was not visible when it was small can be seen as it is zoomed in. Image presentation processing that cannot be realized with an LCD of about 10 to 12 inches, such as when it comes and when it cannot be seen, is possible.

  The game board main body 52F has almost the same function as the conventional one-board game board, and includes a rail 60, a nail 55, a windmill 56, and an accessory unit (a top nail accessory unit 58A and a lottery accessory unit 58B). Specifically, the game balls can be collected at the start winning opening 66 by proceeding with the so-called left-handed launch intensity.

  Here, the game board main body 52F and the ceiling nail accessory unit 58A are provided with through holes 60 and 62, and a game ball related to the ceiling nail 55A can enter the through holes 60 and 62. is there.

  When passing through the through holes 60 and 62, the game ball reaches the flow-down area 52Rarea of the game board main body 52R from the flow-down area 52Farea of the game board main body 52F. That is, in the first embodiment, there are two flow down areas 52Farea and 52Rarea.

  In order to realize these two flow-down areas 52Farea and 52Rarea, in the first embodiment, two game board main bodies 52F and 52R are manufactured by the same production process.

  At this time, there is no problem in driving the game board made of conventional veneer plywood, but when the nail 55 is driven into the game board main bodies 52F and 52R made of transparent acrylic, a crack may be generated from this drive point. There is sex.

  Therefore, in the present embodiment, pilot holes 78 are formed in advance at appropriate locations on the game board main bodies 52F and 52R. The relationship between the outer diameter φa of the nail 55 and the inner diameter φb of the pilot hole 78 is set based on a predetermined fitting tolerance. In the first embodiment, φb is set to φa = 1.85 mm. 1.70 to 1.80 mm.

  After forming such a pilot hole 78, for example, by setting it in an existing nail driver and driving in a nail 55, there is no burden on the game board main bodies 52F and 52R, and in an existing work process, The game board main bodies 52F and 52R can be manufactured.

  In the pachinko machine 10, the pilot hole 78 is required to sufficiently withstand the drop impact of the game ball that flows down, and it is essential that the nail 55 does not fall off. That is, the specification requirement specific to the pachinko machine 10 that the nail 55 is not a structure in which some strength is distributed to each other but an independent obstacle for the purpose of guiding the game ball has not been established. In the form of, this is achieved.

  In the first embodiment, since the arrangement of the nails 55 and the windmills 56 is different in each of the flow down areas 52Farea and 52Rarea, it is possible to enjoy the movement of two types of game balls in one pachinko machine 10. .

  Furthermore, in the first embodiment, the game ball guided from the flow down area 52Farea to the flow down area 52Rarea is returned to the flow down area 52Farea again through the through hole 64, and the position at this time is the start winning opening. It is easy to win 66. Therefore, for the purpose of collecting the game balls at the start winning opening 66, which is the original purpose, a route targeting the through-hole 60 of the ceiling nail accessory unit 58A can be newly established.

  Accordingly, the player can select a new game by selecting from two routes, that is, aiming at the start winning port 66 by hitting the conventional left hand or entangled with the ceiling nails 55A and aiming at the starting winning port 66 via the flow area 52Rarea. Can bring sex.

“Second Embodiment”
The second embodiment of the present invention will be described below. In the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and the description of the configuration is omitted.

  The second embodiment is characterized in that the object, operation, and effect in the first embodiment are the same, but the structure of the game board body is different.

  As shown in FIG. 6, the second embodiment includes a single game board main body 52 </ b> U and an LCD 54. The game board main body 52U and the display surface of the LCD 54 are disposed with a gap slightly larger than the outer diameter of the game ball (currently 11 mm). That is, the front and back surfaces of the game board main body 52U are the flow-down area 52UFarea (corresponding to the flow-down area 52Farea of the first embodiment) and 52URarea (corresponding to the flow-down area 52Rarea of the first embodiment).

  At this time, as a part of the nail 55 provided in the flow-down area 52URarea on the back surface side, a nail 55 longer than a normal length is applied at the same position as the flow-down area 52UFarea on the front surface side, It penetrates and projects to the flow-down area 52URarea on the back side. The tip of the nail 55 is rounded so that the display surface of the LCD 54 is not damaged even if the selection comes into contact with the LCD 54 during assembly work. Note that a protective sheet is generally provided in advance on the display surface of the LCD 54. In other words, the protective sheet is not damaged.

  According to the second embodiment, since the game board main body 52U is single, the number of parts can be reduced. In addition, since the installation space is such that a flow-down area 52URarea is provided between the LCD 54 and the game board main body 52U as compared with the conventional case, a compact full-surface liquid crystal pachinko machine can be realized.

“Third Embodiment”
The third embodiment of the present invention will be described below. Note that in the third embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and description of the configuration is omitted.

  The third embodiment has the same purpose, action, and effect as in the first and second embodiments, but the game board main body production process in the first embodiment is maintained in the past. And, it is characterized by having the compactness in the second embodiment.

  As shown in FIG. 7, in the third embodiment, the front game board main body 52F and the back game board main body 52R in the first embodiment are closely fixed back to back (hereinafter, referred to as “the first game board main body 52R”). The assembly after close-fixing is called “game board body 52assy”).

  The game board main body 52assy and the display surface of the LCD 54 are fixed to each other with a space slightly larger than the outer diameter of the game ball (currently 11 mm). That is, the front and back surfaces of the game board main body 52assy are the flow-down areas 52Farea and 52Rarea, respectively.

  At this time, as a part of the nail 55 provided in the flow-down area 52Rarea on the back surface side, the nail 55 longer than the normal length is applied at the same position as the flow-down area 52Farea on the front surface side, It penetrates and projects to the flow-down area 52Rarea on the back side. The tip of the nail 55 is rounded so that the display surface of the LCD 54 is not damaged even if the selection comes into contact with the LCD 54 during assembly work. Note that a protective sheet is generally provided in advance on the display surface of the LCD 54. In other words, the protective sheet is not damaged.

  In addition, pressure frames 80 are attached to the upper and lower ends of the game board main body 52assy that are fixedly fixed, and pressure is always applied to maintain the adhesiveness.

FIG. 8 illustrates a mating surface when the game board main body 52assy is configured.
FIG. 8A is an enlarged side view of the mating surface of the game board main body 52F and the game board main body 52R. In the third embodiment, water 82 as a solvent is interposed on the mating surface.

There are two reasons why the solvent (water 82) is interposed.
(1) Reflected image reduction by refraction (2) Improving adhesion retention FIG. 8B schematically shows how light is refracted when light is incident on the game board main body 52assy from an oblique direction ( (See the solid line in FIG. 8B). For comparison, the state of refraction when no solvent or the like is interposed (that is, air) is indicated by a chain line.

  The board which is an acrylic material of the game board main body 52assy has a refractive index of 1.5 to 1.8. The refractive index of air is 1.0 and the refractive index of water is about 1.3.

  When the mating surface is air, light is refracted by the difference in refractive index at each interface, and a reflected image (image seen from the player) is generated at this refraction point. That is, when the mating surface is air, the reflected images at the three positions of the front surface, the mating surface, and the back surface of the game board main body 52assy appear to be greatly shifted.

  On the other hand, when the water 82 is interposed, the refractive index difference between the acrylic, which is the material of the game board main body 52assy, and the water 82 is smaller than that of the air, so that the refraction at the mating surface is small. As a result, it is not difficult to see the reflected image at the three positions of the front surface, the mating surface, and the back surface of the game board main body 52assy. The same can be said for the display image from the LCD 54.

  8C and 8D are cross-sectional views further enlarging the state of the mating surfaces. As shown in FIG. 8C, it can be seen that the surface of the acrylic plate is microscopically uneven, and there is a gap even when these are bonded together. On the other hand, FIG. 8 (D) shows a case where water 82 as a solvent is interposed and adhered. Since the water 82 absorbs unevenness, the adhesion can be improved.

  According to the third embodiment, since the game board main body 52U is single, the number of parts can be reduced. In addition, since the installation space is such that a flow-down area 52URarea is provided between the LCD 54 and the game board main body 52U as compared with the conventional case, a compact full-surface liquid crystal pachinko machine can be realized.

  Further, by interposing a solvent (water 82) on the mating surfaces, even if two game board main bodies 52F and 52R are closely fixed back to back, the deviation of the reflected image at the interface where light refraction occurs is reduced. can do.

  Further, the mutual adhesion by the water 82 is improved, and there is no problem that the adhesion state is shifted or dropped in combination with the pressure frame 80.

  In the third embodiment, water 82 is used as a solvent, but a liquid having a predetermined viscosity such as an oil system may be used.
