Next, the variable display device is composed of a display unit (for example, a liquid crystal display device) on which a display unit 21 (screen) capable of displaying identification information (sometimes referred to as a special figure) such as numbers and characters is formed, and is not shown. ) Is built-in, and a special drawing in multiple columns can be displayed. For example, special charts are displayed in three vertical columns on the left, center, and right, and special figures consisting of numbers, letters, etc. in each column are displayed in a stopped state (stop display), or in a fluctuating state (for example, vertically) Display in a scrolling state) (that is, a variable display). In addition, the display unit 21 can display an image for presentation or information notification such as a background image and a character image separately from the special figure.
The variable winning device 12 is a device having a special winning opening 12a that is opened on condition that a big hit, which will be described later, is achieved.
Further, the upper start winning opening 11c and the start winning opening 11 are winning openings that function as a special starting start opening, as will be described later, and the lower finger introduction award opening 11 has openings on both sides as winning openings. Opening and closing members 11a that open and close are provided on both sides. The upper start winning opening 11c is disposed below the center portion of the center case 10, and the start winning opening 11 is disposed directly below the upper start winning opening 11c.

Next, although the general-purpose display is not shown in the drawing, for example, a display that displays a so-called general-purpose display (for example, 7 segments that can display numbers as a general-purpose display, etc.) is arranged on the right side of the variable winning device 12. Of the display).
Although the illustration memory display is not shown in the drawing, it is composed of, for example, small lamps provided at four locations around the illustration display. Depending on the number of lighting of the lamp, The number of usual start-up memories generated by passing through (in this case, the upper limit number is 4) is displayed.

Next, the back side configuration of the game board 1 will be described with reference to FIG.
A casing 30 is attached by a fastening member such as a screw from the center to the upper part on the back side of the board 1a constituting the game board 1, and the above-described variation display device is disposed inside the casing 30. A sub-control unit 31 is detachably provided on the back side of the casing 30 (the back side of the variable display device). A ball gathering member 32 is attached below the casing 30, and a main control unit 33 is detachably provided on the back side of the ball gathering member 32.
The ball gathering member 32 is a member that is arranged in the lower part on the back side of the game board 1 and guides and collects the game balls (winning balls) that have won the winning holes and the winning devices and collected them below the pachinko machine.
The main control unit 33 is a unit that incorporates a game control device and the like for performing control for game progression and overall control of the entire gaming machine. The sub-control unit 31 is a unit that incorporates a variable display device, an effect control device that controls a speaker and lamps (not shown), and the like based on control information transmitted from the game control device.
Note that the casing 30, the ball gathering member 32, and the like correspond to game-related parts.

B. Outline of Game Next, an outline of a game performed in the pachinko machine of the present embodiment and a flow of the game will be described.
First, at the beginning of the game (or before the start of the game), the customer is in a waiting state (during the demonstration), and the customer waiting image (moving image or still image) is displayed on the screen (display unit 21) of the variable display device. ) Is displayed.
When a game ball that has been thrown into the game area 3 via the guide rail 2 wins the upper start winning opening 11c or the start winning opening 11 (that is, when there is a start winning of a special figure), a special figure is displayed on the display unit 21. The change display is performed, and the change display game is played.

  If the stop display mode of the variable display game (a combination of special figures derived by the variable display) is a special display mode (for example, a doublet such as “3, 3, 3”), a privilege called a big hit is obtained. It is given to the player. In terms of control, for example, on the condition that there has been a start winning, the value of the big hit random number is extracted and stored, and the random number value that has been extracted and stored is compared and determined at the time of determination. Based on the determination result, whether or not to make a big hit is determined in advance, and the variable display game is started in response to this determination.

  When the big hit state is reached, an opening operation is performed in which the big prize opening 12a of the variable prize winning device 12 is temporarily released, for example, for a period of up to ten prizes within a range not exceeding a specified time (for example, 30 seconds). Is called. This release operation is performed up to 15 rounds, for example. In this jackpot state, display of the jackpot image for producing the jackpot state or notifying the player of the number of jackpot rounds is executed on the display unit 21.

Further, when a game ball is further won in the upper start winning opening 11c or the starting winning opening 11 during the above-mentioned special figure variable display game or big hit, in this case, a special figure start memory display is performed on the display unit 21, for example. Up to four are stored, and after the variable display game or jackpot is finished, the variable display game of the above-mentioned special figure is repeated or returned to the customer waiting state based on the storage (ie, start memory).
That is, if the variable display game ends with a big hit, the game shifts to a big hit state, and if the variable display game ends with a start and there is a start memory, the variable display game is executed again, and the variable display game ends with a start and no start memory is stored. If the jackpot ends and the start memory is stored, the variable display game is executed again. If the jackpot ends and there is no start memory, the flow returns to the customer waiting state.

On the other hand, when the game ball passes through the usual figure start gate 19 during the game, a usual figure change display game is performed by the usual figure change display on the ordinary figure display. And if this variable display game result (stopped common figure) is a predetermined aspect, the privilege called per figure will be provided.
At this time, a game is held in which the pair of opening and closing members 11a of the start winning opening 11 is held in an open state in which the shape of the opening is reversed, for example, for about 0.5 seconds. As a result, a game ball can be won in the start winning opening 11, and accordingly, the number of executions of the special display variable display game is increased and the possibility of being a big hit increases.
Also, during the above-mentioned variable display game, when a game ball is further won at the general chart start gate 19, a general chart start display is executed on the general chart storage display, and in this case, up to four are stored. After the end of the variable display game shown in the figure, the usual variable display game is repeated based on the memory.

C. Next, the board 1a constituting the game board 1 will be described with reference to FIGS.
FIG. 3 is a perspective view showing a plurality of plate-like bodies constituting the substrate 1a. FIG. 4 is a diagram for explaining an artificial board formed from a wooden board, and FIG. 4 (a) is a front view showing a second particle board (second wooden board). b) is a front view showing a first particle board (first woody plate-like body). FIG. 5 is a side sectional view showing the structure of the substrate 1a, FIG. 5 (a) shows the structure of this embodiment, and FIGS. 5 (b) to 5 (d) show the structures of other embodiments.

As shown in FIGS. 3 and 5A, the board 1a constituting the game board 1 has a plurality of boards (first particle board 41, second particle board 42, third particle board 43, single board 44, single board 45). Is formed by adhering adjacent materials. In this case, the adhesive layer for bonding the plates is much thinner than the thickness of each plate, and is not shown. The overall thickness of the substrate 1a is usually about 2 cm.
The board 1a includes a front layer FL to which the above-described front-side game-related parts (center case 10, start winning port 11 and the like) are attached, and the above-described back-side game-related parts (casing 30 and ball gathering member 32 and the like). Are attached to the back layer BL, and an intermediate layer CL formed between the front layer FL and the back layer BL. In this example, the front layer FL is constituted by a single plate 44, the back layer BL is constituted by a single plate 45, and the intermediate layer CL is constituted by a first particle board 41, a second particle board 42, and a third particle board 43, respectively. Yes.

Here, the veneer 44 and the veneer 45 are natural plates cut from a natural tree (for example, a veneer made by peeling off a tree such as beech). The single plate 44 and the single plate 45 are used to prevent the game nail 5 and the like from coming off and when a fastening member (for example, a member such as a screw 6 shown in FIG. 5) for fastening game-related parts is fastened. It is provided to prevent drowning, and is further provided to improve the appearance by the grain.
The first particle board 41, the second particle board 42, and the third particle board 43 are so-called particle boards. The particle board is a kind of wood-based artificial board manufactured from a plurality of pieces of wood, and is generally a plate-like body formed by mixing a small piece of wood with an adhesive and compression molding.
In this example, the first particle board 41 and the third particle board 43 are formed by compression molding a fine piece of wood as shown in FIG. 4B, and correspond to the first woody plate-like body of the present invention. Further, as shown in FIG. 4A, the second particle board 42 is formed by compression molding a piece of wood larger than the first particle board 41 and the third particle board 43, and corresponds to the second woody plate-like body of the present invention. To do.

  Further, in this case, the single plate 44 that is the front layer FL and the first particle board 41 that is a part of the intermediate layer CL are the game-related parts on the front side (the game nail 5, the center case 10, the start winning opening 11 and the like). The drop-off prevention layer SL on the front surface side that attaches the cover is configured. On the other hand, the single plate 45 which is the back layer BL and the third particle board 43 which is a part of the intermediate layer CL are attached to the back side where the game-related parts (casing 30, the ball-feeding member 32, etc.) are fastened. A drop prevention layer SL is configured. The drop-off prevention layer SL is a layer for preventing a drop-off of a fastening member (for example, a member such as a screw 6 shown in FIG. 5) for fastening the game nail 5 or other game-related parts. As shown in FIG. 5, the drop-off prevention layer SL is formed with a thickness that allows almost the entire area of the fixing portion of the fixing member and the entire area where the game nail 5 is implanted (the portion embedded in the board 1a) to be inserted. Has been.

As shown in FIG. 4A, the second particle board 42 is formed by compressing a piece of wood such as waste material into fine pieces and using an adhesive. However, since the size of the crushed piece of wood is not uniform, the driving strength (fixed strength) of the game nail 5 is not sufficient. For example, when the board 1a of the game board 1 is configured only by the second particle board 42, the game nail 5 may come off if the game nail 5 that has been struck is struck for adjustment at the time of shipment.
On the other hand, as shown in FIG. 4B, the first particle board 41 and the third particle board 43 are crushed so that the pieces of wood are fine and substantially uniform, and compression-molded using an adhesive. As a result, the first particle board 41 and the third particle board 43 have substantially uniform shapes, so that when compressed, the wooden pieces are firmly bonded to each other, and the game nail 5 is driven and adjusted. Can prevent the game nail 5 from coming off.
Further, as the first particle board 41 and the third particle board 43, so-called MDF (Medium-Density Fiberboard) may be used. The MDF is a kind of the artificial board, and is a board formed by crushing pieces of wood into fibers and compressing them by adding an adhesive. This MDF has a finer and smoother surface and superior strength as compared with a particle board.

According to the gaming machine of this example described above, the board 1a constituting the gaming board 1 is configured between the front layer FL and the back layer BL to which game-related parts are attached, and the front layer FL and the back layer BL. The front layer FL and the back layer BL are made of natural plates (single plates 44, 45) cut and manufactured from trees, and the intermediate layer CL is made up of a plurality of pieces of wood. Since the wood-based artificial board to be manufactured (the first particle board 41, the second particle board 42, and the third particle board 43) is used, the amount of natural board used can be reduced.
Therefore, the consumption of natural resources can be reduced, and a gaming machine that cooperates in preventing environmental destruction such as deforestation can be obtained.
Further, since natural plates (single plates 44 and 45) are used for the front layer FL and the back layer BL of the substrate 1a as in the past, it is necessary to introduce new equipment to form the game board 1. In addition, the production burden can be prevented.

  In addition, a part of the front layer FL and the intermediate layer CL (single plate 44 and the first particle board 41), or a part of the back layer BL and the intermediate layer CL (single plate 45 and the third particle board 43), game-related parts The fall-off prevention layer SL for preventing the fall-off of the fastening member for fastening the seat is formed, and the fall-off prevention layer SL is formed with a thickness that allows almost the entire fastening portion of the fastening member to be inserted. Can be firmly held on the game board. Therefore, it is possible to prevent the occurrence of problems such as a game ball colliding with game-related parts and falling off from the game board 1.

  The game-related parts include a game nail 5 with which a game ball to be used for the game collides, and the drop-off prevention layer SL is inserted through almost the entire area where the game nail 5 is planted, so that the game nail 5 is attached to the game board. 1 can be held firmly. Therefore, it is possible to prevent the occurrence of problems such as a game ball colliding with the game nail 5 and dropping from the game board 1.

  The artificial board includes a first wood plate (first particle board 41 and third particle board 43) obtained by compression molding a fine piece of wood, and a second wood obtained by compression molding a piece of wood larger than the first wood plate. A first wood-based plate-like body (second particle board 42), and the first wood-based plate-like body is disposed on the front layer side and the back-surface layer side with respect to the second wood-based plate-like body. Since the wooden plate-like body is part of the drop-off preventing layer SL, the game-related parts and the game nails 5 can be firmly held on the game board 1. Therefore, it is possible to prevent the occurrence of problems such as the game ball colliding with the game-related parts and the game nail 5 and falling off the game board 1. Moreover, since the relatively cheap 2nd wood type plate-shaped body which compression-molded the wooden piece larger than the 1st wood type plate-shaped body is used for the center side of the board | substrate 1a, the cost reduction of the game board 1 can be aimed at. .

  The particle board is generally used in the furniture industry, and is also used in a slot machine housing and a part of an outer frame of a pachinko machine in the field of gaming machines. However, when used in these, there is no frequent attachment and detachment of the fixing member such as a screw once attached, and there is no continuous pressure applied like a game nail. There is no problem as long as it has a certain strength. On the other hand, the game balls 1 continuously flow down on the game board 1, and the pressure applied to the game nails 5 and other components provided on the game balls 1 is not normal. When pressure from the game ball is applied for a long time, even the metal game nail 5 breaks or falls off the game board 1. If a general particle board is used in such a place, it cannot withstand the pressure. However, in the case of the game board 1 made of the substrate 1a of this example, since the drop-off prevention layer SL as described above is provided, it is possible to prevent the game nails 5 and the like from falling off and to reduce the usage amount of the natural board.
