Description

  The present invention relates to a board of a game board for a ball game machine that has a plate-like base material made of a resin material, and is used by driving a large number of game nails into a game area formed on the front side of the base material. Concerning structure.

  Conventionally, laminated plywood (plywood) using beech material or lauan material has been widely used as a base material for game boards used in ball game machines. Game boards are generally made by adhering decorative cells to the front surface of such a base material, forming holes for attaching game parts such as center ornaments, winning devices, rail members, etc. The game nail is driven in and the game parts are mounted and fixed with screws (for example, see Patent Document 1). On the other hand, in recent years, the price of laminated plywood, which is the material of the base material, has soared, and problems with mass consumption of wood have been pointed out from the viewpoint of natural environment protection, and attempts to use synthetic resin as a substrate material to replace laminated plywood Is being implemented at each gaming machine manufacturer.

JP 2006-239193 A

  However, when a game nail is driven into a base material made of a resin material, there is a problem in that the volume of resin is pushed away by the driven nail, causing distortion in the surroundings and deforming the entire base material. . For example, if a large number of game nails are stopped from the front side of the base material (in a form in which the game nails do not penetrate the base material), the distortion on the front side of the base material is larger than that on the rear side, and the front side is bent convexly. When a game nail with a tip having a diameter larger than that of the shaft is driven into the vicinity of the rear surface, the distortion on the rear side is larger than that on the front side, resulting in a bent shape with a concave front surface. There was a problem.

  On the other hand, in order to reduce distortion, it is conceivable to form a pilot hole for driving a nail prior to driving a game nail. However, if a pilot hole is mechanically drilled by using a machine tool such as a multi-axis drilling machine, a problem that a large amount of time is required for machining a large number of pilot holes exceeding 200 per machine and productivity is not increased. In addition, it is necessary to change the tool placement setting in accordance with the gauge setting every time the production model is changed, and there is a problem that setup is not easy. In addition, if the resin is machined, a large amount of heat is generated and heat tends to accumulate in the cutting tool, and if a small-diameter hole is continuously drilled, the hole diameter varies and it is difficult to securely fix the game nail. There has been a problem that production management becomes complicated.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a board structure of a game board that can suppress deformation of a resin base material without complicating production management.

In order to solve the above problems and achieve the object, the present invention has a plate-like base material made of a resin material, and a large number of game nails are driven into a game area formed on the front side of the base material. 1 is a board structure of a game board for a ball game machine (for example, a game board 10 for a pachinko machine PM in the embodiment). In addition, the present invention is configured by forming a plurality of slit-like groove portions extending in a plane along the plate surface and having a depth in the plate thickness direction of the substrate. From the first groove portion (for example, the groove portion 61a in the embodiment) formed to open on the front surface side of the substrate and the second groove portion (for example, the groove portion 62a in the embodiment) formed to open on the rear surface side of the substrate. becomes, Ru first groove and the second groove is formed arranged alternately.

In the present invention, the first groove, it is preferable to absorb the larger distortion at the substrate front side in a large number of gaming nails are pouring in discontinuation Mari the nailing set from the front side of the substrate.

In the present invention, the second groove portion, the distortion of the rear face side which is relatively larger than the substrate front side in the nailing setting implanted from the front side to the rear surface near the thick gaming nail diameter of the distal end portion of the substrate It is also preferable to absorb

  The board structure of the game board according to the present invention is configured by providing a plurality of slit-like grooves on the base material that have a depth in the thickness direction of the base material and extend in a plane along the plate surface. In the base material provided with such a groove portion, the internal stress generated around the game nail by placing the game nail is released by the slit-like groove portion and is not transmitted across the groove portion. In other words, distortion due to the placement of the game nail is absorbed in the groove portion, and the influence of the distortion does not occur in the opposite portion across the groove portion. For this reason, by providing a plurality of such groove portions at appropriate positions, deformation of the entire substrate can be reduced. Further, according to this configuration, a process that is difficult to manage for production such as making a large number of pilot holes having a smaller diameter than the game nail is not required. Therefore, it is possible to provide a game board in which deformation of the resin base material is suppressed without complicating production management.

In the present invention, according to the configuration of the first groove portion formed by opening the groove portion on the front surface side of the base material, in the case of setting to lay many game nails from the front surface side of the base material, The distortion on the front side of the base material can be absorbed by each groove portion opening to the front side, and deformation of the base material on which the front side tends to be convex can be efficiently reduced.

In the present invention, according to the configuration of the second groove portion formed by opening the groove portion on the rear surface side of the base material, when the game nail having a large tip end portion is driven to the vicinity of the rear surface, Therefore, the distortion on the rear surface side that becomes larger can be absorbed by the groove portion that opens to the rear surface side, and the deformation of the base material that tends to be concave on the front surface side can be efficiently reduced. In addition, when the base is formed of an opaque resin material, or when the nail placement area is covered with a cell or the like, a groove may be provided on the back side of the game area visually recognized by the player. For example, it is possible to effectively reduce deformation of the base material by forming a groove between adjacent game nails in an area where game nails are densely packed.

And in this invention, it comprises from the 1st groove part which opens a groove part to the front surface side of a base material, and the 2nd groove part which opens to a rear surface side, These 1st groove parts and 2nd groove parts are arranged side by side alternately By adopting the structure to form, it is possible to flexibly absorb the distortion generated in the base material with the front and rear grooves, whether it is a nail setting for stopping game nails or a nail setting using a game nail with a thick tip The deformation of the base material can be reduced regardless of the selection of the game nail and the setting of the driving depth.

  Therefore, according to this invention, the board structure of the game board which can suppress a deformation | transformation of a resin-made base material can be provided, without complicating production management.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. As an example of a ball game machine equipped with a game board to which the present invention is applied, a front view of a pachinko machine PM is shown in FIG. 1, and a front view of a game board 10 mounted on the pachinko machine PM is shown in FIG. First, the overall configuration of the pachinko machine PM will be outlined with reference to these drawings.

  In the pachinko machine PM, a front frame 2 for opening and closing mounted on a front surface of an outer frame 1 configured to have a predetermined frame size of an outer rectangular shape and forming a vertically fixed holding frame is formed on the front surface of the opening and closing of the rectangular frame size corresponding to this. The frame hinge mechanisms 3a and 3b arranged on the upper left and right sides of the front side are attached to the front so as to be able to be opened and closed laterally and attached to and detached from each other. The locking device 4 provided on the right side of the front is always used to engage the outer frame 1. When connected, they are kept closed.

  On the front side of the front frame 2, a rectangular glass door 5 and a bowl unit 6 adapted to the front side area are assembled so that they can be opened and closed sideways and attached / detached by hinge mechanisms 7 a, 7 b, 7 c provided on the left side of the front side. Attached and always kept closed using the locking device 4. A launch handle 8 for performing a launch operation of the game ball is provided at the lower right side of the ball tray unit 6. An upper part of the front frame 2 is provided with an accommodation frame that detachably accommodates and holds the game board 10, and the game board 10 configured with a predetermined gauge setting is detachably attached to the accommodation frame. The player can face the game area PA on the front through the glass window 5a of the glass door 5 held closed.

  The game board 10 is based on a rectangular plate-like base material 11, and a substantially circular game area PA in which a game ball can roll is formed on the front side of the game board 10 and surrounded by guide rails 12. In the game area PA, together with a large number of game nails 13, a windmill 14, a fixed prize device 15a, movable prize tools 15b, 15c, a winning device 15 such as a start gate 15d, a display opening in the center, and a frame shape are formed. A central ornament 20 having a corrugated rolling stage and a selection mechanism in the frame portion, a liquid crystal display panel 25 attached to the back side of the central ornament 20 and displaying an image according to game development, etc. At the lower end of the area PA, there is provided an out port 16 through which game balls that have fallen without falling into the winning device 15 are discharged to the back surface of the game board 10. Each part of the pachinko machine is provided with an electrical decoration device 28 that is blinked in accordance with game development.

  Although not shown in detail on the back side of the front frame 2 located behind the game board 10, a mechanism set board called a back set board is attached to a ball storage tank or a ball payout device. And a ball processing mechanism such as a game ball discharge passage for guiding game balls such as safe balls and out balls discharged from the game board 10 to a collection device of the game facility. In addition, on each part of the rear surface of the back set board, there are a main control board that comprehensively controls the operation of the pachinko machine PM, and an operation of the liquid crystal display panel 25, the electric decoration device 28, a speaker, etc. In accordance with the operation signal from the launching handle 8 and the control board for controlling the operation of the ball dispensing device based on the command signal from the main control board. Various circuit boards such as a launch control board for controlling the operation of the game ball launcher are attached, and these are connected by a connector cable so that the pachinko machine PM can be operated.

  In the pachinko machine PM generally configured as described above, as shown in FIG. 3, the game board 10 includes a rectangular plate-like base material 11, a game nail 13 and a windmill. 14 is formed to form a board 31, and the board 31 is provided with a rail member 17 provided with a fixing hole of a clamp mechanism for fixing the guide rail 12 and the game board, a fixed prize 15a, a movable prize 15b, A winning device 15 such as 15c and a start gate 15d, and game parts such as a central decoration 20 are sequentially attached.

  The substrate 11 is made of a resin material such as polycarbonate (PC), acrylic resin (PMMA), or ABS resin having a plate thickness of 8 to 15 mm. For example, the substrate 11 is configured using a flat polycarbonate having a plate thickness of about 10 mm. Here, when the game nail 13 or the windmill nail is directly driven into the base material 11, the resin having a volume equal to the volume of the driven nail is pushed to the periphery, and an internal stress is generated around the nail. The same applies to the periphery of the fixing screw for attaching the winning device 15, the central ornament 20, the rail member 17, and the like. When these internal stresses are applied to the entire base material, the base material 11 is bent into a shape corresponding to the stress distribution. Therefore, in the game board of the present invention, a groove structure that blocks transmission of the generated internal stress is formed in each part of the base material 11 to adopt a plate structure that suppresses deformation of the whole base material.

As a configuration example of the plate structure according to the present invention, FIG. 4 shows a schematic configuration of a plate structure 51 of the first embodiment (a form having only a first groove portion of the present invention to be described later) . The plate structure 51 will be described. Here, FIG. 4 is a front view of the base material 11 immediately before the nail driving process for placing the game nail 13. In the following, the up / down / left / right directions are defined with reference to the mounting posture shown in FIG. 1 where the game board 10 is attached to the pachinko machine PM, the front direction orthogonal to the paper plane is the front, and the back direction orthogonal to the paper plane (game) The rear surface direction of the board 10 will be referred to as rear and will be described.

  The plate structure 51 of the first embodiment has a depth in the thickness direction of the base material 11 on the outer side (outer peripheral side than the guide rail 12) of the game area PA in the base material 11 and is in the plane of the base material. A plurality of slit-like groove portions 61 (61a, 61b, 61c) extending along the surface are formed. Each groove is formed to open on the front side of the base material 11, for example, does not penetrate the base material 11 like the groove 61 a, and has a predetermined groove depth of about 5 to 8 mm from the front side of the base material 11. It is formed to open only on the side, or like the groove portions 61b and 61c, it is formed by penetrating through the base material 11 and opening on both front and rear surfaces.

  The extending direction of the groove portion 61 is formed in a plurality of directions. In the illustrated embodiment, a configuration example in which a groove portion extending in the horizontal direction and a groove portion extending in the vertical direction is shown. The extending direction of the groove portion is not limited to the horizontal / vertical direction, and may be formed in, for example, an arc shape matching the contour shape of the guide rail 12 or a radial shape extending from the guide rail 12 in the outer peripheral direction.

  On the other hand, the groove width W of the groove portion 61 (61a, 61b, 61c) is a width that can block the transmission of stress, that is, a width that does not contact the inner wall surface of the groove when the game nail 13 is distorted. It may be sufficient, and can be set as appropriate according to the processing means for forming the groove 61. For example, when the groove portion 61 is formed by router processing together with the mounting hole 75 of the winning device 15 (fixed winning tool 15a, movable winning tools 15b and 15c, start gate 15d), the mounting hole 78 of the central ornament 20, etc. When the diameter of the tool that can be processed by the router is about 3 to 10 mm and these component mounting holes 75 and 78 are formed simultaneously when the base material 11 is molded, it is about 1 to 3 mm depending on the configuration of the mold. Set. In addition, when the component mounting holes 75 and 78 are formed by laser processing, an arbitrary groove width equal to or larger than the cutting width (approximately 0.5 mm) of the base material 11 according to the focused spot diameter of the laser beam, can do.

  As described above, in the plate structure 51 of the first embodiment in which the groove portion 61 is formed, distortion due to the placement of the game nail 13 is absorbed by the groove portion 61 (61 a, 61 b, 61 c) and is distorted in the opposing portion across the groove portion 61. Does not occur. Therefore, the deformation of the entire substrate can be reduced by a simple means for forming a plurality of grooves. In addition, since the groove portion 61 is formed to open on the front side of the base material 11, in the case of a nail driving setting (see FIG. 7) in which a large number of game nails are stopped from the front side of the base material 11, Distortion that increases on the front side of the base material can be absorbed by each groove, and deformation of the base material that tends to be convex on the front side can be reduced.

  Further, since the groove portion 61 is formed outside the game area PA, the front portion is covered by the rail member 17 to be mounted thereafter, and the groove portion 61 is not visually recognized by the player (see FIGS. 1 and 2). Reference), even if the substrate 11 is made of a transparent resin. Further, the insertion hole 32 of the clamp mechanism formed outside the game area PA, the game-completed ball discharge passage 33 for discharging the out-ball, the positioning hole 35 that serves as a reference for the position and processing of the game board 10, and the rail decoration The positions and shapes of the 17 mounting guide holes 77 and the like are determined by the type of the front frame 2 in the pachinko machine on which the game board 10 is mounted, and are common regardless of the type of the pachinko machine. For this reason, the groove part 61 can be formed together with other common structure parts 32, 33, etc. in the injection shaping process for forming the base material 11, and a gaming board in which the deformation of the base material is reduced by such a manufacturing method. It can be produced at low cost.

  In addition, as shown in the blow-out part enclosed by a two-dotted line in FIG. Even in the PA, it is possible to form the groove 61c penetrating in the front-rear direction.

Next, a plate structure 52 of a second embodiment (a form having only a second groove portion of the present invention described later) will be described with reference to FIG. FIG. 5 is a front view of the base material 11 (the board 31 in FIG. 3) after the game nail 13 and the windmill 14 are driven and fixed to the base material 11. In the plate structure 52 of the present embodiment, slit-shaped grooves 62 (62a, 62b) and 63 that have a depth in the thickness direction of the base material 11 and extend along the plate surface within the surface of the base material 11 A plurality of materials 11 are formed on the rear side of the material 11. The groove part 62 provided on the outside of the game area PA is the same as the groove part 61 of the first embodiment described above, formed on the back side of the base material 11 opposite to the front and back sides, and like the groove part 62a, It is formed to open only to the rear surface side with a predetermined groove depth of about 5 to 8 mm from the rear surface side of the base material 11, or is formed to penetrate the front and rear surfaces of the base material 11 and open to both front and rear surfaces like the groove portion 62b. The The groove part 62 (62a, 62b) is configured in the same manner as the groove part 61 (61a, 61b) described above, except that the opening direction of the groove is opposite to the front surface and the back surface.

  On the other hand, the groove 63 is located on the inner side of the game area PA (inner peripheral side than the guide rail 12), and is located between the adjacent game nails 13 and 13 in an area where a large number of game nails 13 are densely driven. It is formed in the position. The extending direction of the groove 63 can be appropriately formed according to the arrangement pattern (gauge setting) of the game nails 13, and, for example, like the groove 63 of the portion indicated by the reference symbol A in FIG. A group of game nails 13, 13, which are formed in a short groove shape for partitioning each group between a plurality of groups of game nails, or arranged in a line, such as a groove portion 63 with a reference numeral B. 13... Are located in the middle of the game nails 13, 13, 13... 13, 13, 13. And formed along the direction in which each row extends. At this time, the grooves as described above can be combined so that the grooves intersect each other.

  The groove width of the groove portion 63 may be any width as long as the stress transmission can be interrupted in the same manner as described above. When the groove portion 63 is formed together with the component mounting holes 75 and 78 of the gaming parts by router processing, the router processing is possible. When the groove width is about 5 mm and formed by laser processing, the groove width can be about 0.5 mm according to the focused spot diameter of the laser beam.

  As described above, in the plate structure 52 of the second embodiment in which the groove portion 63 is formed, the internal stress generated around each game nail by the placement of the game nails 13, 13, 13... It is released at 63, 63, 63... And is not transmitted beyond the nearest groove. Further, the distortion caused by the driving of the game nail 13 is absorbed by the nearest grooves 63, 63, 63..., And does not cause distortion on the opposite side of the groove. For this reason, it is possible to prevent deformation of the entire base material due to accumulation of stress and strain by appropriately providing such groove portions 63 according to the arrangement pattern (gauge setting) of the game nails 13.

  In addition, since the groove portion 63 is formed to open on the rear surface side of the base material 11, a game nail having a screw or knurl formed at the front end and a diameter of the front end portion larger than that of the shaft portion is driven near the rear surface of the base material 11. In such a nail driving setting, the distortion on the rear surface side that is relatively larger than the front surface side can be properly absorbed by the groove portion 63, and the deformation of the base material 11 that tends to be concave on the front surface side is efficiently reduced. be able to. Such a groove portion 63 is formed so that the base 11 is formed using an opaque resin material, or the front surface is covered with a cell or a seal attached to a region where the game nails 13 are densely placed. In such a case, the deformation of the base material 11 can be effectively suppressed without affecting the appearance design of the pachinko machine.

Next, the plate structure 53 of the third embodiment (the form according to the present invention) will be briefly described with reference to FIG. FIG. 6 is a cross-sectional view taken along a plane orthogonal to the plate surface of the substrate 11, where the left side in the drawing is the front surface of the substrate 11 and the right side is the rear surface of the substrate 11. In the plate structure 53 of the present embodiment, the slit-shaped groove portion formed in the base material 11 opens to the first groove portion 61a formed on the front surface side of the base material 11 and the rear surface side of the base material 11. The second groove 62a is formed, and the first groove 61a and the second groove 62a are alternately arranged. That is, the plate structure 53 of the present embodiment includes the groove portions 61a of the first embodiment described above and the groove portions 62a of the second embodiment, and these are alternately formed.

  According to the plate structure 53 having such a configuration, even if the nail setting is such that the game nail 13 is stopped from being driven or the nail setting using a game nail having a large tip is used, The distortion generated in the material 11 can be flexibly absorbed by the front and rear grooves 61a and 62a formed alternately in parallel, and the deformation of the base material 11 regardless of the selection of the game nail 13 or the setting of the driving depth. Can be reduced.

7 and 8 show another configuration example of the plate structure (a form not included in the present invention) . Both figures are sectional views cut along a plane orthogonal to the plate surface of the base material 11 as in FIG. 6, and the groove 66 shown in FIG. 7 extends from the outer peripheral end surface of the base material 11 along the plate surface of the base material 11. It is formed to extend inward of the substrate. According to the plate structure in which such a groove portion 66 is formed, stress transmission in the plate thickness direction of the substrate 11 is blocked by the groove portions 66, 66..., And distortion in the plate thickness direction can be reduced. The upper half of FIG. 8 is a plate structure in which a square tubular groove 67 is formed along the plate surface of the substrate 11 from the outer peripheral end surface of the substrate 11, and the lower half of FIG. 8 is orthogonal to the plate surface of the substrate 11. It is a structural example of the plate structure which combined the groove part 61a of the direction and the groove part 66 along the plate surface of the base material 11, and according to these plate structures, the direction along the plate surface of the base material 11, and a plate | board thickness direction Propagation of internal stress in both directions is blocked at each groove, and distortion of the substrate 11 can be reduced.

  As described above, in the present invention, the base plate 11 is provided with a plurality of slit-like grooves, and the board structure of the game board 10 is configured. In such a plate structure, since the internal stress generated around the nail by the game nail 13 is released at the groove and is not transmitted beyond the groove, the deformation of the entire base material can be reduced. . Further, according to the present invention, it is possible to easily manufacture in a simple production process without requiring difficult production management such as making a large number of pilot holes having a smaller diameter than the game nail 13. Therefore, according to the present invention, it is possible to provide a game board in which distortion of the resin base material is reduced without complicating production management.

  In the embodiment, the example in which the present invention is applied to the pachinko machine PM, which is a representative example of a ball game machine, has been described. However, other types of ball game machines such as an arrange ball machine and a sparrow ball game machine are also described. It can be applied in the same manner, and the same effect can be obtained.
