BACKGROUND OF THE INVENTION
The present invention relates to a game board of a game machine such as a pachinko machine using a game ball and a slot machine using a medal, and a manufacturing method thereof .
[0002]
[Prior art]
The game board of the pachinko machine has a cell sheet on which the design drawing is drawn on the back side and is integrally connected to the front side of the game board formed in a substantially square shape with wood such as veneer, and is used to attach game functional parts. A through hole is formed. Further, the back surface of the game board has a dent used for positioning a game function component attached to the back surface of the game board.
[0003]
[Problems to be solved by the invention]
By the way, when forming a through hole and a recess in the game board, if the through hole is drilled from the front side of the game board, that is, the cell sheet side, and the recess is drilled from the back side of the game board, that is, the game board side, Drilling is a two-step process, which is economically disadvantageous.
[0004]
For this reason, as shown in FIG. 7, when the through hole 50 and the recess 51 are drilled in one step from the back side of the game board 52, the drill 53 is used when the through hole 50 is formed. When the sheet is pulled out to the front side, the cut edge of the cell sheet 54 may be peeled off from the game board 55 and turned up. When this turning-up occurs, cutting waste 56 such as sawdust enters between the turned-up cell sheet 54 and the game board 55, and the periphery of the through hole 50 of the cell sheet 54 is on the front side of the game board 52. It will remain swelled. When this cell sheet 54 is raised and gaming functional parts such as tulips, center bonuses, winning holes, and attackers not shown are attached to the front of the gaming board 52, the height of the gaming functional parts is unreasonably high. In addition, game function parts may be distorted.
[0005]
If the gaming functional parts are unreasonably high, there is a disadvantage that the glass is damaged when the gaming board 52 is assembled to a machine frame attached to an island of a pachinko store and the glass of the machine frame is closed. When the game function part has a movable part, the movable part may malfunction due to the distortion, which may impair the gameability. Therefore, after drilling, between the cell sheet 54 and the game board 55, The cutting waste 56 that has entered is manually removed, and there is a limit to cost reduction.
[0006]
In order to eliminate such an inconvenience, as shown in FIG. 8, a hole is machined from the back side of the game board 52 by superposing a veneer-like wooden floor plate 57 on the cell sheet 54 of the game board 52. However, the floor board 57 is likely to warp due to moisture absorption, which is one of the characteristics of natural wood, and when this warpage occurs, a gap 58 is formed between the mating surfaces of the cell sheet 54 and the floor board 57. In the gap 58, the same inconvenience as described above occurs, and it is difficult to adopt it.
[0007]
Therefore, the present invention forms a cut line in the cell sheet that is larger than the through-hole and hidden by the gaming functional parts attached to the through-hole to prevent the cell sheet from turning up around the through-hole. It is an object of the present invention to provide a gaming machine gaming machine capable of improving the performance and a manufacturing method thereof .
[0008]
[Means for Solving the Problems]
Game board of the gaming machine according to the present invention, a through-hole for accommodating the body portion of the game functional components straddling the game board attached to the front surface depicted cell sheet and a design diagram of this cell sheet and, Ru insert city from the side into the through-hole of the cell sheet body portion of the game functional component into the through hole, by overlapping flange projecting outwardly from the body portion of the game functional components on the front of the cell sheet mounting In the gaming board of a gaming machine, the cell sheet has a cut line surrounding the through hole formed outside the peripheral edge of the through hole and hidden by the flange of the gaming functional component, and in a region surrounded by the cut line The cell sheet is removed from the game board at the cut line .

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 2 shows the first embodiment, and the gauge board 31 is an interior of a machine frame of a pachinko machine that includes an outer frame that is attached to an island of a pachinko store and a front frame that is openably and closably attached thereto. A ball launcher (not shown) is attached to a game board 9 in which a cell sheet 1 having a design drawing is integrally coupled to the entire front surface of a game board 2 constituted by a substantially square plywood board. A band 32 for guiding a game ball launched from the game area to the game area, a center role 33, a lamp windmill 34, a windmill 35, a start opening 36, a general winning opening 37, a large winning opening 38, an out opening 39, a side lamp 40, an award. Various game functional parts 43 such as a ball lamp 41 and a stop lamp 42, and a large number of game nails 44 are provided. In FIG. 2, in order to simplify the drawing, a plurality of light-emitting display portions 1 a to 1 g and non-light-emitting display portions 1 h made of electroluminescence lamps to be described later are not shown.
[0010]
As shown in FIG. 1, the game function part 43 protrudes in a closed ring shape from a main body portion 43 a housed in a through-hole 29 formed in the game board 2 of the game board 9 and from the front edge of the main body portion 43 a. The flange 43b is attached to the front surface of the cell sheet 1 of the game board 9 by a wood screw (not shown). A cut line 15 is formed in the cell sheet 1 in a range L outside the through hole 29 formed in the game board 2 and hidden by the flange 43b.
[0011]
In this embodiment, as shown also in step 301 of FIG. 3, the cell sheet 1 has a dotted line on the back surface of a front panel 1i made of a transparent polyethylene terephthalate film (referred to as PET film) having optical transparency. A plurality of light emitting display portions 1a, 1b, 1c, 1d, 1e, 1f, and 1g made of the electroluminescence lamp shown in FIG. 2 and non-light emission formed by normal paint printing that is a portion other than the light emitting display portions 1a to 1g. It has a design drawing composed of a display unit 1h.
[0012]
The cell sheet 1 has a surface electrode 1j formed by vacuum deposition on the entire back surface of a front panel 1i having a square size almost congruent with the game board 2 made of tabloid or veneer shown in step 302. A light emitting layer 1k corresponding to the light emitting display portions 1a to 1g and a non-light emitting layer 1m corresponding to the non-light emitting display portion 1h are formed in parallel on the back surface of the formed surface electrode 1j by multicolor printing. is there.
[0013]
In this embodiment, the light emitting layer 1k is formed on the surface electrode 1j by using a light emitting layer printing screen having a material for forming the light emitting layer 1k in the light emitting layer forming portion and excluding the material other than the light emitting layer forming portion. Multi-color printing self-alignment (positioning) is taken and printed on the back side.
[0014]
The non-light-emitting layer forming portion has a coating for forming the non-light-emitting layer 1m, and the non-light-emitting layer 1m is a surface electrode 1j. The self-alignment is performed on the back surface of the substrate with reference to the positioning portion at the time of self-alignment, and is printed.
[0015]
Although the printing of the light emitting layer 1k and the non-light emitting layer 1m has been described in two steps, in practice, each of the light emitting layer 1k and the non-light emitting layer 1m is in a state of providing a plurality of design drawings in multiple colors. Since it forms a pattern that appeals to human vision, it usually takes two or more steps, and either the light-emitting layer 1k or the non-light-emitting layer 1m may be printed first, but the thickness of the printed layer If the thin layer is printed first, the material or paint for forming the light-emitting layer 1k and the non-light-emitting layer 1m printed on the front side is prevented from being transferred to the printing screen used thereafter. The fixing waiting time can be shortened, and the printing time of the light emitting layer 1k and the non-light emitting layer 1m can be shortened.
[0016]
Next, after the light emitting layer 1k and the non-light emitting layer 1m arranged in parallel on the back surface of the surface electrode 1j are fixed, the entire surface of the back surface of the surface electrode 1j is covered so as to cover the back surface of the light emitting layer 1k and the back surface of the non-light emitting layer 1m. After the insulating layer 1n is formed by printing and the insulating layer 1n is fixed, the back electrode has a material for forming the back electrode 1p in the back electrode forming portion and the material other than the back electrode forming portion is removed. The back electrode 1p is formed on the flat back surface of the insulating layer 1n by the self-alignment using the positioning part at the time of the self-alignment as a reference, and is formed and fixed by printing.
[0017]
Thereafter, a protective layer 1q is formed on the entire back surface of the insulating layer 1n including the back electrode 1p by printing in a state of covering the back electrode 1p, and after the protective layer 1q is fixed, the flat back surface of the protective layer 1q A fixing sheet 1s such as a Kent sheet formed substantially in the same shape as the front panel 1i is bonded to the entire surface by pressing the adhesive layer 1r in an overlapped state and integrally.
[0018]
And the laminated body which consists of this surface panel 1i, the surface electrode 1j, the light emitting layer 1k, the non-light emitting layer 1m, the insulating layer 1n, the back electrode 1p, the protective layer 1q, the adhesive layer 1r and the fixing paper 1s has a size like a tabloid size. In this case, the cell sheet 1 is completed by die-cutting into a rectangular shape substantially the same as the game board 2.
[0019]
In order to couple the cell sheet 1 and the game board 2, for example, as shown in step 303, the back surface of the game board 2 is mounted on the fixed plate 3 and the movable plate heated to a predetermined temperature by the electric heater 4. By pressing 5 to the front surface of the game board 2 mounted on the fixed plate 3 with a predetermined pressure, the front surface of the game board 2 is dried by heating and pressurizing the game board 2 for a predetermined time.
[0020]
As shown in step 304, the emulsion type adhesive 6 such as vinyl acetate is uniformly applied to the entire front surface of the game board 2 in a state where the latent heat due to the heating is retained, and then the process proceeds to step 305. As shown in the figure, the back surface of the fixing sheet 1s of the cell sheet 1 is overlaid on the adhesive 6, while the game board 2 on which the cell sheet 1 is overlaid is fixed to the movable plate 7 having no heater as shown in step 306. By sandwiching with the plate 8 at a predetermined pressure and pressurizing for a predetermined time, a pressure in a direction facing each other is applied to the front side of the cell sheet 1 and the back side of the game board 2, and the game is performed by throwing connection with the adhesive 6. The game board 9 in which the cell sheet 1 and the game board 2 are integrally coupled is obtained by integrally coupling the board 2 and the cell sheet 1 with the fixing paper 1s interposed therebetween.
[0021]
Then, as shown in step 307, positioning holes 12 and 13 are formed in the game board 9 from the front side of the game board 9, that is, from the cell sheet 1 side by cutting using the drills 10 and 11. In this cutting process, an automatic drilling operation using a multi-axis drilling machine is performed, and a guide rail mounting hole (not shown) using a drill (not shown) is formed from the cell sheet 1 side simultaneously with the formation of the positioning holes 12 and 13. It is usual to form. These positioning holes 12 and 13 are arranged at corners of a pair of diagonal positions of the game board 9 so as to be hidden by game function parts (not shown) attached to the front surface of the game board 9.
[0022]
In this embodiment, as shown in step 308, the pilot hole 14 for attaching a game nail, a game functional part, etc. (not shown) to the front side of the game board 9 is pressed using a press machine called a gauge press machine. Since the cut line 15 is formed at the same time as the formation, the press gauge plate 17 attached to the ram 16 of the gauge press machine includes a punch 18 for forming the pilot hole 14 and a cutting blade for forming the cut line 15. 19.
[0023]
Accordingly, the gaming board 9 having been drilled by the multi-axis drilling machine is removed from the multi-axis drilling machine, and the positioning holes 12 and 13 of the gaming board 9 are projected onto the surface plate 20 as a work mounting base of the gauge press machine. After the game board 9 is mounted on the surface plate 20 of the gauge press machine by being fitted and mounted on the plurality of positioning pins 21 and 22 provided from above, the press gauge plate 17 is driven by driving the ram 16 of the gauge press machine. Is lowered, and a pilot hole 14 and a cut line 15 are formed by pushing the front side of the game board 9, that is, the front side of the cell sheet 1 and the game board 2.
[0024]
Further, in this embodiment, as shown in step 309, since a punching machine having a numerical control function called a router machine is used, the game board 9 removed from the gauge press machine is turned over, Positioning holes 12 and 13 of the board 9 are fitted and mounted from above to a plurality of positioning pins 24 and 25 projecting on a surface plate 23 as a work mounting base of the router machine, and the game board 9 is connected to the router machine. It is mounted on the surface plate 23. The surface plate 23 of this router processing machine has support protrusions 26 and 27 at portions other than the portion where a through hole 29 described later is formed, and the cell sheet 1 of the game board 9 is placed on these support protrusions 26 and 27. In the mounted state, the game board 9 is mounted on the router processing machine, and the game board 9 is turned upside down by pressing the peripheral edge of the game board 9 from above with a bracket (not shown) of the router processing machine. It is fixed to the board 23.
[0025]
In this state, by driving the router machine based on preset numerical data, the game board 9 positioned and mounted on the surface plate 23 of the router machine is fixed to the game board 9 from the back side of the game board 9. Through holes 29 and depressions 30 are formed by cutting with a cutting tool 28 such as a drill or an end mill of a router machine.
[0026]
When the formation of the through hole 29 is completed, the game board 9 is removed from the router machine, so that a plurality of through holes 29 are formed on the front surface of the game board 9 at the cut line 15 of the cell sheet 1 as shown in FIG. In addition to the through hole 29, a recess 30 is formed on the back surface of the game board 9 as shown in FIG. 5. After that, the game board 9 is turned over again from the state shown in step 309 in FIG. 3, and is transferred to the next process with the front side of the game board 9, that is, the cell sheet 1 facing upward.
[0027]
At the transport destination, as shown in FIG. 2, the band 32 is attached to the front surface of the game board 9 by using the band attachment hole not shown above and the center hole using the through hole 29. 33, various wind function parts 43 such as a lamp windmill 34, a windmill 35, a start opening 36, a general winning opening 37, a large winning opening 38, an out opening 39, a side lamp 40, a prize ball lamp 41, a stop lamp 42 and the like are attached. By attaching the game nails 44, the gauge board 31 of the pachinko machine is completed. In the completed gauge board 31, as shown in FIG. 1, the cut line 15 formed in the cell sheet 1 is concealed by the flange 43 b of the game function part 43.
[0028]
Therefore, according to this embodiment, after the cut line 15 is cut and formed in the cell sheet 1, the through hole 29 is formed in the game board 9 composed of the cell sheet 1 and the game board 2 within the region surrounded by the cut line 15. By using the cutting tool 28, when the cutting edge of the cutting tool 28 passes through the cell sheet 1, the part surrounded by the cut line 15 of the cell sheet 1 (the part corresponding to the through hole 29) is cut. Separating from the line 15, it is possible to reliably prevent the cell sheet 1 from turning up around the through-hole 29, and even when the recess 30 is formed on the back side of the game board 9, there is no need to change the drilling procedure, The through hole 29 and the recess 30 can be appropriately drilled with a small number of steps.
[0029]
In particular, in this embodiment, the cutting edge 19 for forming the cut line 15 is provided on the press gauge plate 17 used for forming the prepared hole 14 that is performed prior to the cutting of the through hole 29 in the game board 9. Simultaneously with the formation of the pilot hole 14 by the press gauge plate 17, the cut line 15 can be formed on the cell sheet 1 by pressing, thereby reducing the work man-hours and incidental facilities. Further, even if the router processing is performed in a state where the adhesive 6 is not completely dried, the cell sheet 1 will not be peeled off, so the cost can be reduced by increasing the speed between the processes and selecting the adhesive 6. I can plan.
[0030]
Moreover, in this embodiment, since the positioning holes 12 and 13 are formed in the game board 9, when forming the cut line 15 and the through-hole 29, the positioning holes 12 and 13 of the game board 9 are made into each processing machine. By fitting into the provided positioning pins 21, 22, 24, 25, the cut line 15 and the through hole 29 can be mechanically formed accurately and coaxially.
[0031]
In addition, since the through-hole 29 is large, the diameter of the cut line 15 is increased, and the portion of the cell sheet 1 that forms the inside of the cut line 15 is extracted in a large size when the through-hole 29 is cut. If there is a possibility that the cutting part may clog the cutting dust suction duct in the router processing machine, an auxiliary blade such as a cross shape is provided inside the cutting blade 19, and a cut line is formed in the large cutting part. If an auxiliary cut line that can be cut finely at the same time as the 15 cut-off process is formed by push-cutting, it is possible to prevent the inconvenience of clogging in the duct.
[0032]
FIG. 6 shows a second embodiment, in which a closed annular projection 43c is provided on the back surface of the flange 43b of the game function component 43, and the cell sheet 1 is formed by the projection 43c when the game function component 43 is attached to the game board 9. The vicinity of the cut line 15 is compressed and pressed to improve the waterproofness of the electroluminescent lamp and to extend its life.
[0033]
In each of the above-described embodiments, a pachinko machine using a game ball has been described as an example. However, the present invention can be applied to a slot machine using medals by replacing the game function part 43 attached to the game board 9.
