Description

  The present invention relates to a ball game machine such as a pachinko machine.

  Patent Document 1 discloses a composite sheet for a ball game machine substrate in which a transparent film made of PET (polyethylene terephthalate) is laminated on the surface of a transparent resin sheet made of acrylic resin via an adhesive layer. The ratio of the thickness (adhesive layer thickness / transparent film thickness) is set to 1 / 1.5 to 1/3.

  Patent Document 2 describes a game board in which a PET resin film is attached to the front surface of an acrylic resin base via an adhesive layer. Resin film has a smaller coefficient of linear expansion than the base, and when the base contracts due to a temperature drop, there is a possibility that the peripheral part of the resin film insertion hole interferes with the nail press-fitted into the bottom hole of the base and floats up. The shape of the pilot hole is a stepped shape having a large-diameter portion having an inner diameter larger than the outer diameter of the body portion of the nail and a small-diameter portion into which the nail is press-fitted. The inner diameter is set equal to or larger than the inner diameter of the large diameter portion of the hole.

JP 2010-279466 A Japanese Unexamined Patent Publication No. 2009-211988

  When a composite sheet (laminated plate) is formed by adhering a transparent film (design sheet) made of PET to the surface of a transparent resin sheet (game board) made of acrylic resin as in Patent Document 1 with an adhesive layer, Since the linear expansion coefficient of the thin-walled design sheet is smaller than that of the thick-walled game board made of acrylic resin, it is difficult for the design sheet to follow the expansion and contraction of the game board due to temperature change. In order to increase the adhesive strength by increasing the thickness of the adhesive layer and to prevent the occurrence of wrinkles and peeling of the design sheet during expansion and contraction of the laminate due to temperature changes, It is necessary to set the thickness of the layer / the thickness of the transparent film to 1 / 1.5 to 1/3, and the increase in the thickness of the adhesive layer causes the appearance to deteriorate.

  In the game board of Patent Document 2, as in Patent Document 1, the linear expansion coefficient of the thin resin film (design sheet) is smaller than the linear expansion coefficient of the thick base (game board). It is necessary to increase the adhesive strength by increasing the thickness of the agent layer (adhesive layer), and increasing the thickness of the adhesive layer causes a deterioration in appearance.

  Therefore, an object of the present invention is to surely prevent the occurrence of wrinkles and peeling of the design sheet when the laminate is expanded or contracted due to a temperature change, and to improve the appearance of the laminate.

  In order to achieve the above object, according to a first aspect of the present invention, there is provided a space in which the front surface of the game board includes a game area, the game board is inclined to flow down the game ball and the flow direction is changed by a plurality of game nails. A ball-and-ball game machine in which a game area is divided based on a predetermined guide rail, and the game board includes a game board made of light-transmitting resin (for example, acrylic resin) and at least one of a front surface or a rear surface of the game board And a laminated sheet made of a cellulosic resin design sheet attached to the adhesive layer. The linear expansion coefficient of the cellulosic resin is greater than or equal to the linear expansion coefficient of the light-transmitting resin.

  The design sheet can reduce the visibility to the rear side of the game board in accordance with the planar area of the game board on which a plurality of game nails are arranged (for example, a pattern that blocks the visual recognition partially or entirely) A predetermined colored design surface (such as a picture) is applied.

  The laminated plate is provided with an inclined hole inclined according to the inclination of the game board with respect to the colored design surface so that the game nail can be inserted, and at least a guide rail is provided. A non-inclined hole substantially perpendicular to the game board is formed in the outer peripheral portion based on the formation of the game board.

  Moreover, the ratio of the thickness of the adhesive layer to the thickness of the design sheet is preferably 1/5 or more and 1/30 or less.

  In addition, a plurality of these inclined holes are adjacent to the design sheet attached to the game board so that the adjacent intervals of the plurality of inclined holes are close to each other and not less than twice the nail head larger than the body of the game nail. These inclined holes can be drilled.

  In the above configuration, since the linear expansion coefficient of the thin-walled design sheet made of the cellulose-based resin is equal to or larger than the linear expansion coefficient of the thick-walled game board made of light-transmitting resin, The design sheet can easily follow the shrinkage. For this reason, it is possible to achieve both improvement in appearance due to thinning of the adhesive layer and prevention of generation of wrinkles and peeling of the design sheet at the time of expansion and contraction of the laminate due to temperature change.

  The second aspect of the present invention is the ball game machine according to the first or second aspect, wherein the design sheet is attached to the front surface of the game board. The laminated board has a plurality of first attachment holes for attaching predetermined parts and a plurality of second attachment holes for planting a plurality of game nails for changing the flow direction of the game ball. The first mounting hole is a stepless non-inclined hole that continues from the front surface of the design sheet to the game board with substantially the same diameter and extends substantially orthogonal to the laminated board. The second mounting hole has a diameter larger than the diameter of the body part so as to be slightly separated from the body part of the game nail and penetrates the design sheet, and a bottom surface of the front hole part concentrically with the front hole part A stepped inclined hole having a small-diameter rear hole portion that continues to the game board and extends rearward and downward with respect to the laminated board.

  The predetermined part may be a windmill having a shaft insertion hole, a body portion of the game nail inserted through the shaft insertion hole, and a body portion provided with a distal end portion in the game area of the game nail. The windmill may be rotatably mounted on the front surface of the laminated plate by fitting into the first mounting hole having substantially the same diameter.

  In the above configuration, since the front hole portion having a diameter larger than that of the body portion of the game nail is formed on the front side of the second mounting hole in which the game nail is implanted, the game nail is brought into contact with the flowing game ball. Even if it vibrates, the body portion of the game nail does not interfere with the design sheet, and the design sheet can be prevented from peeling off due to the interference with the game nail.

  Further, since the first mounting hole is a stepless hole, the drilling work for forming one first mounting hole is only once, and the number of work steps can be reduced. In addition, since the fixed nail inserted in the first mounting hole for mounting a predetermined part is not easily affected by vibration due to contact with the game ball, the fixed nail is also a fixed nail even if the first mounting hole is a stepless hole. The design sheet is unlikely to peel off due to the interference.

  ADVANTAGE OF THE INVENTION According to this invention, while the generation | occurrence | production of the wrinkles of generation | occurrence | production or peeling of the design sheet at the time of expansion | swelling of a laminated board by the temperature change or shrinkage | contraction, etc., it can prevent the appearance of a laminated board.

The design sheet 122 may be attached to the rear surface of the game board 121 instead of or in addition to the front surface of the game board 121.

The linear expansion coefficient of the cellulosic resin (design sheet 122) is greater than or equal to the linear expansion coefficient of the acrylic resin (game board 121). For example, the linear expansion coefficient of the cellulosic resin is 7 × 10 ⁻⁵ / ° C. to 16 × 10 ⁻⁵ / ° C., and the linear expansion coefficient of PMMA is 7 × 10 ⁻⁵ / ° C.

  The ratio of the thickness of the adhesive layer 123 to the thickness of the design sheet 122 (the thickness of the adhesive layer 123 / the thickness of the design sheet 122) is 1/5 or more and 1/30 or less. If the ratio of the thickness exceeds 1/5, the appearance of the adhesive layer 123 may be deteriorated, and if it is less than 1/30, sufficient adhesive strength cannot be ensured. , Is set to a predetermined thickness within the above range.

  Further, the adjacent intervals of the plurality of inclined holes according to the above are such that the plurality of inclined holes are close to each other in a state where the nail head 132 is slightly larger than the trunk portion 134 of the game nail 110 and is not more than twice the nail head 132. When a hole is drilled, the setting is such that the generation of wrinkles and peeling of the design sheet 122 is suppressed during the drilling.

  As shown in FIG. 7, the laminated plate 120 has a plurality of first mounting holes 126 for mounting the plurality of components 125, and a plurality of second mounting holes 127 for planting the plurality of game nails 110. Is formed.

  As shown in FIGS. 10 and 11, the game nail 110 includes a shaft-shaped body portion 134, a head portion 132 formed at one end of the body portion 134, and a knurled shape formed at the other end of the body portion 134. And a front end portion 133 of the same.

  As shown in FIG. 8 (e), the first attachment hole 126 is continuous from the front surface of the design sheet 122 to the game board 121 with substantially the same diameter, and is stepless and non-inclined extending substantially orthogonal to the laminated plate 120. It is a hole. The inner diameter of the first mounting hole 126 is set to be approximately the same depending on the outer diameter of the tip of a fixing nail (not shown) necessary for fixedly supporting the component 125. The component 125 is fixed to the game board 5 by fitting the fixing nail into the first mounting hole 126 (for example, heating and press-fitting) so that it can be supported (standing) with a predetermined strength.

  For this reason, the fixed nail inserted into the first attachment hole 126 is in an insertion state that easily interferes with the inner edge of the first attachment hole 126 of the design sheet 122.

  When the component 125 is the windmill 111, the game nail 110 is used as a fixed nail. As shown in FIG. 11, the wind turbine 111 has a shaft insertion hole 134 that penetrates forward and backward. The body portion 134 of the game nail 110 is inserted into the shaft insertion hole 134, and the first attachment 133 having a diameter substantially the same as the diameter of the body portion 134 provided in the game area 8 is provided at the body portion 134 of the game nail 110 inserted. By inserting into the hole 126a (shown in FIG. 7), the windmill 111 is attached to the front surface of the laminated plate 120 so as to be rotatable in response to contact with the game ball flowing down in the game area 8.

  Since the fixing nail inserted into the first mounting hole 126 for mounting the windmill 111 (predetermined part) is not easily affected by the rotation of the windmill 111 due to contact with the game ball, the first mounting hole Even in the case where the design sheet 122 relating to the insertion that interferes with the fixed nail is set as a stepless hole 126, peeling of the design sheet 122 due to the vibration of the fixed nail hardly occurs.

  As shown in FIG. 9 (d), the second mounting hole 127 has a large-diameter front hole portion 130 that penetrates the design sheet 122, and a game board 121 concentrically with the front hole portion 130 from the bottom surface of the front hole portion 130. A stepped inclined hole having a small-diameter rear hole portion 131 that is continuous with the laminated plate 121 and extending rearward and downward with respect to the laminated plate 121. The inner diameter of the front hole portion 130 is set to be slightly larger than the outer diameter of the body portion 134 of the game nail 110 (for example, 1.5 mm or less exceeding the outer diameter of the body portion 134), and the inclination of the second mounting hole 127 The angle is inclined according to the inclination of the game board 5 and is generally set uniformly at a predetermined angle (about 5 degrees in the present embodiment) with respect to the orthogonal direction of the game board 121. In addition, you may make it give the exceptional angle setting to the game nail 110 arrange | positioned around a predetermined winning opening.

  Further, the large-diameter front hole portion 130 only has to penetrate the design sheet 122. When drilling according to the inclination, the drill 136 penetrates the design sheet 122 and reaches the game board 121. Drilling is finished.

  The inner diameter of the rear hole portion 131 is set to be approximately the same as the outer diameter of the body portion 134 of the game nail 110.

  As shown in FIG. 10, the game nail 110 is supported (standing upright) with a predetermined strength with respect to the laminated plate 120 by fitting the front end 132 of the game nail 110 into the rear hole 131 (for example, heating and press-fitting). ) It is installed in the game board 5 as possible. In this state, the inner edge of the second mounting hole 127 (front hole portion 130) formed in the design sheet 122 is separated from the body portion 134 of the game nail 110, so that the game ball and the game nail flowing down the game area 8 are used. The peeling off of the design sheet 122 due to the vibration generated from the contact of 110 becomes difficult to occur.

  Accordingly, it is preferable that the front hole portion 130 having a diameter slightly larger than the outer diameter of the body portion 134 is set as a minimum size so as not to interfere with each other due to vibration of the technique nail 110. is there.

  The distance between the adjacent second mounting holes 127 is set to be larger than the outer diameter of the head 132 of the game nail 110. For example, the game ball flowing down the game area 8 is guided in the direction of a predetermined winning opening. Alternatively, they are arranged in a row so that the balls are distributed differently from the direction of the winning opening.

  As shown in FIG. 7, a plurality of (two in this embodiment) positioning holes 128 are formed in the laminated plate 120 in addition to the first mounting holes 126 and the second mounting holes 127. The positioning hole 128 is a stepless non-inclined hole similar to the first mounting hole 126, and is disposed in the vicinity of the corner of the laminated plate 120. The positioning hole 128 is used as a positioning hole when the laminated plate 120 is set in a processing machine for attaching the component 125 or the like to the laminated plate 120, a nailing machine for installing the game nail 110 on the laminated plate 120, or the like.

[Lamination of laminated board]
Next, the punching process of the laminated plate 120 will be described with reference to FIGS. FIG. 8A shows a state before processing the laminated board 120 (game board 121), and FIG. 8B shows a state where the surface protection sheet 129 is peeled off from the front surface of the game board 121 and the design sheet 122 is attached. ) Shows a state in which the surface protection sheet 129 is reattached to the front surface of the design sheet 122, (d) shows a state in which the first attachment holes 126 are formed in the laminated plate 120, and (e) shows a state in which the first attachment holes 126 are formed. Each of the states after forming is shown. 9A shows a state in which the front hole portion 130 of the second mounting hole 127 is formed, FIG. 9B shows a state after the front hole portion 130 is formed, and FIG. 9C shows a state in which the front hole portion 130 is formed. (D) shows the state after formation of the rear hole part 131, respectively.

  A protective sheet 129 for protecting the surface of the game board 121 is attached to both surfaces (front and rear surfaces) of the game board 121 before the punching process (FIG. 8A). The protection sheet 121 is a resin film such as polyethylene or polypropylene. Before processing, the surface protection sheet 129 is peeled off from the front surface of the game board 121, the game board 121 is set in a cell pasting machine (not shown), and the design sheet 122 is pasted to form the laminate 120 (FIG. 8 ( b)). Next, the laminated plate 120 is set in a protective sheet attaching machine (not shown), and the surface protective sheet 129 is reattached to the front surface of the design sheet 122 (FIG. 8C), and then the laminated plate 120 is placed in the vertical hole. The first mounting hole 126 and the positioning hole 128 are formed by a drill 135 after being set on a processing machine (not shown) (FIGS. 8D and 8E). As the drill 135, a drill having an outer diameter corresponding to the inner diameter of the hole to be formed is used. Next, after the laminated plate 120 is set in a counterbore processing machine (not shown) and the front hole portion 130 of the second mounting hole 127 is formed by the large-diameter drill 136 (FIGS. 9A and 9B). Then, the laminated plate 120 is set in a 5-degree drilling machine (not shown), and the rear hole portion 131 is formed by a small-diameter drill 137 (FIGS. 8C and 8D).

  The game nail 110 is planted and the component 125 and the like are attached to the laminated plate 120 that has been subjected to the drilling process. The protective sheet 129 is peeled from the laminated plate 120 at a predetermined timing such as before the game nail 110 is planted or when the back cover 124 is attached.

  According to this embodiment, since the linear expansion coefficient of the thin-walled design sheet 122 made of cellulosic resin is equal to or greater than the linear expansion coefficient of the thick-walled game board 121 made of acrylic resin, the game board 121 due to temperature change. It is easy for the design sheet 122 to follow the expansion and contraction. For this reason, the improvement of the appearance by thinning of the adhesive layer 123 and the prevention of the occurrence of wrinkles or peeling of the design sheet 122 when the laminated sheet 120 expands or contracts due to a temperature change are achieved. Can do.

  In addition, since the front hole portion 130 having a diameter larger than that of the body portion 134 of the game nail 110 is formed on the front side of the second mounting hole 127 in which the game nail 110 is implanted, by contacting the game ball flowing down, Even when the game nail 110 vibrates, the body portion 134 of the game nail 110 does not interfere with the design sheet 122, and the design sheet 122 can be prevented from being peeled off due to the interference with the game nail 110.

  Further, since the first mounting hole 126 is a stepless hole, the drilling work for forming one first mounting hole 126 is only required once, and the number of work steps can be reduced. Note that the fixed nail inserted into the first mounting hole 126 for mounting the component 125 is not easily affected by vibration due to contact with the game ball. Therefore, the fixed nail can be formed even if the first mounting hole 126 is a stepless hole. The design sheet 122 is unlikely to peel off due to the interference.
