Description

  The present invention relates to a ball game machine including a game board having a transparent synthetic resin game board and image display means such as liquid crystal display means arranged on the back side of the game board.

  The game board used in the game board of the ball game machine is made of a synthetic resin having skin layers on both the front and back sides of the foam layer in addition to the conventional wooden board such as a plywood board (Patent Document 1). There is a synthetic resin product (patent document 2) in which a nail hole is formed in the protruding boss portion. This game board made of synthetic resin is due to demands that it is difficult to obtain as the wood resources decrease, and that recycling that can be reused as resources after disposal can be easily promoted.

  On the other hand, instead of using a synthetic resin game board as an alternative to a wooden game board in recent ball game machines, the entire game board is made transparent by taking advantage of the characteristics of the synthetic resin material. A liquid crystal display means of a size corresponding to the game area is arranged on the back side of the game board so that the image of the liquid crystal display means on the back side can be displayed on substantially the entire game area of the game board. Has been.

  The game board using the former foaming material can be driven into the game nail using a nailing machine in the same manner as the wooden board after being molded. In the latter game board, since the nail hole is formed in advance, the game nail may be inserted into the nail hole.

  However, in the case of a transparent game board, it is very difficult to drive a game nail after molding unlike a foam material, and even if it can be driven, Distortion may occur, which may be an obstacle to seeing through the image of the liquid crystal display means on the back side.

  Further, when a boss portion having a nail hole is provided on the back side of the transparent game board, the back side of the game board becomes uneven and the thickness becomes uneven, so that the liquid crystal display means is provided via the game board. There is a drawback that the image is distorted when seeing through the image.

  Therefore, when a transparent synthetic resin material is used for the game board and the image of the liquid crystal display means on the back side can be seen through the game board, a game nail is driven after the game board is molded. Of course, when the game board is molded, it is not possible to integrally form a boss portion having a nail hole and insert the game nail into the nail hole after molding.

  The present invention has been made in view of the above-described conventional problems, and an object of the present invention is to provide a ball game machine that can easily and inexpensively manufacture a game board with a game nail and can prevent as much as possible obstacles to seeing through the image on the back side. And

The present invention provides a ball game machine comprising a game board having a transparent synthetic resin game board and an image display device disposed on the back side of the game board, wherein the game board is formed in a penetrating manner in the front-rear direction.

  As shown in FIG. 3, the game board 5 has an outer guide rail 18 and an inner guide rail 19 mounted on the front surface of the game board 16, and starts at a predetermined site such as the lower side of the game area A inside the inner guide rail 19. Predetermined gaming parts such as the means 22, the big winning means 23, the normal winning means 24 and the like are mounted, and the ball guiding heel 25, the game nail 26 and the like are provided at predetermined portions such as the upper part and the left and right sides.

  As shown in FIGS. 2, 4, and 5, the game board 16 includes a nail holding plate 27 in which a large number of game nails 26 are attached in a penetrating manner, and a back plate 28 that is superimposed on the back surface of the nail holding plate 27. The nail holding plate 27 and the back plate 28 are integrated by a holder 29 that is detachably provided on the outer peripheral side. The nail holding plate 27 is a transparent synthetic resin flat plate having sufficient strength to hold the game nail 26, and a large number of nail holes 30 for the game nail 26 are penetrated in the front-rear direction by machining such as drilling. In addition, a mounting hole for mounting each gaming component such as the starting means 22, the big winning means 23, or a ball passage is formed in a penetrating shape in the front-rear direction by machining such as drilling. .

  As shown in FIGS. 6 (a) and 6 (b), the game nail 26 has a hemispherical head portion 26b on the front end side of the round bar-shaped main body portion 26a and a spherical spherical end on the rear end side of the main body portion 26a. Each has a portion 26c, and the spherical end 26c side is inserted into the nail hole 30 from the front side by press fitting or the like. The nail hole 30 is formed in a slightly upward shape according to the mounting angle of the game nail 26 with respect to the game board 16, and the inner diameter thereof is around the nail hole 30 of the nail holding plate 27 when the main body portion 26 a of the game nail 26 is press-fitted. The diameter of the main body 26a is slightly smaller so that cracks and other distortions do not occur.

  The back plate 28 is used to prevent the game nail 26 from being driven when adjusting the nail. The back plate 28 is overlapped with the back surface of the nail holding plate 27 so that the substantially entire surface of the back plate 28 contacts the back side of the nail holding plate 27 evenly. Yes. A flat plate material harder than the nail holding plate 27 is used for the back plate 28, and the spherical end portion 26c of the game nail 26 is in contact with or close to the front surface thereof. In addition, the back plate 28 has a mounting hole corresponding to the mounting hole of each game component such as the starting means 22 on the nail holding plate 27 side, the big winning means 23, or a ball path corresponding to the ball path, etc. It is formed in a penetrating shape in the front-rear direction by processing.

  The holding tool 29 includes a nail holding plate 27 and a back plate 28 between the nail holding plate 27 and the back plate 28, and a holding frame 29a having an L-shaped cross section and the like, and the holding frame 29a. A pressing frame 29b that sandwiches the outer peripheral side in the front-rear direction is provided, and the pressing frame 29b is detachably fastened to the holding frame 29a by a plurality of screws 29c in the circumferential direction. The holder 29 can be disassembled into a holding frame 29a and a holding frame 29b as needed by removing the screw 29c. Therefore, the game board 16 can be separated into the nail holding board 27 having the game nail 26 and the back board 28 on the back side by disassembling the holder 29. Note that a notch 29d is provided in a lower portion of the front side of the holding frame 29a at a portion where the game ball passes from the firing rail 11 to the guide rails 18 and 19 side.

  As shown by a dotted line in FIG. 3, the liquid crystal display means 6 displays an image of the special symbol display unit 32 at a position corresponding to the upper center of the game area A, and displays other demo images, background images, and the like in the peripheral part. It is supposed to be displayed. The special symbol display unit 32 displays a plurality of, for example, three special symbols 32a in the left-right direction, and the special symbol 32a fluctuates for a predetermined time on the condition that the starting means 22 detects the game ball, After the change, the game is stopped at any one of the jackpot symbol of the specific mode and the other off symbol. In addition, when the special symbol 32a stops at the jackpot symbol, a special game state in which the big winning means 23 is opened is generated.

  Guide means (not shown) for guiding the game ball that has passed through the back side of the game board 5 through the starting means 22, the big prize means 23, etc. to the outside of the machine board 5 is provided in the lower part on the back side of the game board 5. .

  When the game board 5 is manufactured, the nail holding plate 27 and the back plate 28 are manufactured using a predetermined transparent synthetic resin flat plate. For example, the nail holding plate 27 is formed by cutting a predetermined flat plate material to a predetermined size, machining a mounting hole or the like at a predetermined portion, and forming a plurality of nail holes 30 in a predetermined arrangement at a predetermined portion. Both the mounting hole and the nail hole 30 are formed in the nail holding plate 27 so as to penetrate therethrough. For this reason, it is easy to remove shavings such as swarf and the like, and the shavings and the like do not accumulate at the bottom of the hole, so that the work can be performed easily and efficiently.

  After the hole processing, the nail holding plate 27 is set in a nail driver, and the main body portion 26a of the game nail 26 is inserted into each nail hole 30 of the nail holding plate 27 by press-fitting from the front side. In this case, since the game nail 26 is inserted into the nail hole 30 from the spherical end 26c side of the main body 26a, the game nail 26 can be smoothly press-fitted without being caught by the inner peripheral edge of the front end of the nail hole 30. Each game nail 26 can be fixed to the nail holding plate 27 by the press-fitting.

  Similarly, after mounting holes and the like are drilled in the back plate 28, the back plate 28 is overlaid on the back surface of the nail holding plate 27, and the nail holding plate 27 and the back plate 28 are positioned so that the mounting holes and the like match. In this state, the nail holding plate 27 is assembled by integrally joining with the holding tool 29.

  In this assembled state, the spherical end 26 c of the game nail 26 is in contact with or close to the back plate 28. Therefore, even if the game nail 26 is hit in the driving direction when adjusting the nail of the game nail 26, the back plate 28 can prevent the game nail 26 from being driven. Therefore, the height of each game nail 26 can be kept substantially constant without the height of the game nail 26 changing. Further, since the spherical end 26 c of the game nail 26 corresponds to the back plate 28, the tip of the game nail 26 does not pierce the back plate 28.

  In particular, by separating the nail holding plate 27 into which the game nail 26 is inserted and the back plate 28 that prevents the game nail 26 from being driven in, the nail holding plate 27 is compared with PETG, MMA, PVC, etc. at low cost. The nail holding plate 27 and the back plate are selected by selecting a material that is soft and suitable for press-fitting and holding the game nail 26, and for the back plate 28, such as a PC and selecting an optimum material for preventing the game nail 26 from being driven. The optimum material for each of the 28 can be freely selected.

  Further, the nail holding plate 27 and the back plate 28 are not bonded and are integrally held by the outer peripheral side holding tool 29 so as to be separable. Even if it breaks, it can be easily removed by separating the nail holding plate 27 and the back plate 28 and then punching out the remaining portion in the nail hole 30 on the nail holding plate 27 side. Therefore, operations such as repair when the game nail 26 is broken and replacement when the game component is damaged can be easily performed.

  FIG. 7 illustrates a second embodiment of the present invention. The holder 29 on the outer peripheral side of the game board 16 may be as shown in FIG. 7 (a) or (b). In FIG. 7A, a screw 29e is provided through the holding frame 29a through the nail holding plate 27 and the back plate 28 and screwed to the holding frame 29b, and is fastened by this screw 29e. The screw 29e may be inserted from the holding frame 29b side and screwed into the holding frame 29a.

  In FIG. 7B, a plurality of clamp claws 29g are provided in a circumferential direction pivotally supported around a support shaft 29f on a rectangular holding frame 29a having an L-shaped cross section. The clamp claw 29g is rotated around the support shaft 29f between the clamp position and the release position.

  The nail holding plate 27 and the back plate 28 may be integrated by the holder 29 having such a configuration, and is not limited to a specific structure. However, when the handling of the game board 5 at the time before being attached to the game board mounting frame 17 is taken into consideration, the structure in which the outer peripheral side of the nail holding plate 27 is surrounded by the holder 29 prevents the damage. Effective above.

  8-10 illustrate a third embodiment of the present invention. The game board 16 of this embodiment has a three-plate structure by arranging a front plate 33 and a back plate 28 with small gaps S1, S2 on both front and rear sides of the nail holding plate 27. As described above, the game board 16 may have a multilayer structure of three or more including the nail holding board 27.

  In the three-plate game board 16, the nail holding plate 27 that holds the game nail 26 is the thickest, and the front and rear front plates 33 and the back plate 28 are less than half of the nail holding plate 27 and are substantially the same thickness. The back plate 28 is slightly thicker than 33. The nail holding plate 27, the front plate 33, and the back plate 28 are held by a holding tool 29 with spacers 34 and 35 interposed on the entire circumference between the outer peripheral portions thereof.

  A nail hole 30 for a game nail 26 is formed in the nail holding plate 27 as in the first embodiment, and the game nail 26 is inserted into the nail hole 30 by press fitting. A small hemispherical recess 36 corresponding to each game nail 26 is formed in the back plate 28 by machining or the like, and the spherical end 26 c of the game nail 26 abuts or approaches the back plate 28 in the recess 36. is doing. The front plate 33 is formed with a through hole 37 through which the main body portion 26a of the game nail 26 penetrates in a loose fit through a predetermined gap such as a minute gap. The spacers 34 and 35 are configured in a frame shape, but may be divided for each side. Each plate 27, 28, 33 is a flat plate.

  By disposing the front plate 33 on the front surface of the nail holding plate 27 in this way, the nail holding plate 27 can be protected from both the front and rear sides with a hard plate material, and damage to the game board 16 can be prevented as much as possible. In particular, since the game ball moves in the game area A along the front surface of the front plate 33, the use of a hard material for the front plate 33 can prevent the occurrence of contact marks of the game ball.

  If there is a front plate 33 through which the game nail 26 penetrates on the front side of the nail holding plate 27, if the game nail 26 is press-fitted into the through hole 37 of the front plate 33, the front plate 33 is nailed when the game nail 26 is press-fitted. There is a concern that the gap S1 between the nail holding plate 27 and the front plate 33 may be reduced in the central portion of the game board 16 due to the bending of the holding board 27. However, since the game nail 26 is loosely fitted in the through hole 37 of the front plate 33, the gap S1 between the nail holding plate 27 and the front plate 33 can be kept constant. Further, since the spherical end portion 26c of the main body portion 26a is fitted in the recess 36 of the back plate 28, the nail holding plate 27 and the back plate 28 can be positioned by this.

  Further, the game board 16 is divided into a nail holding plate 27, front and rear front plates 33, and a back plate 28, and a small gap S1 is provided between the nail holding plate 27 and the front and rear front plates 33 and the back plate 28. , S 2, the front and rear front plates 33 and back plate 28 can alleviate or disperse the impact so that no direct impact is applied to the nail holding plate 27 having the game nail 26.

  In this embodiment, since the game nail 26 with the head 26b is inserted into the through hole 37 of the front plate 33, the game nail 26 is not pulled out after the game nail 26 is inserted into the nail holding plate 27. As long as the nail holding plate 27 and the front plate 33 cannot be separated. Therefore, the front frame 4 may be fixed to the nail holding plate 27 in advance separately from the back plate 28. In addition, minute gaps S1 and S2 are provided between the nail holding plate 27 and the front and rear front plates 33 and 28. The front plate 33 and the back plate 28 are in surface contact with both front and rear surfaces of the nail holding plate 27. You may let them. In that case, the game nail 26 may be press-fitted into the through hole 37 of the front plate 33.

  FIG. 11 illustrates a fourth embodiment of the present invention. The holding tool 29 on the outer peripheral side of the game board 16 may be as shown in FIGS. 11 (a) to 11 (d), the holding frame 29a has a U-shaped cross section that is detachably fitted to the end edges of the nail holding plate 27, the back plate 28, and the front plate 33 from the outside. It is divided into a plurality of pieces in the circumferential direction, such as four pieces for every two pieces or two pieces for every two adjacent sides, and the respective opposing end portions are connected by screws 29h. Thus, the holding tool 29 is detachably fitted to the game board 16 from the outside, and the holding tools 29 are coupled to each other, or each holding tool 29 is fixed to the game board 16 with screws 29h or the like. May be.

  11 (a) and 11 (b), the spacers 34 and 35 are integrally provided in the holding tool 29, and in FIGS. 11 (c) and 11 (d), grooves 34a and 35a are provided in the holding tool 29. Spacers 34 and 35 are detachably inserted into 34a and 35a.

  12 and 13 illustrate a fifth embodiment of the present invention. Between the nail holding plate 27 and the back plate 28, between the nail holding plate 27 and the front plate 33, etc., between the plates 27, 28 and 30 adjacent to each other in the front and back, as shown in FIGS. Other sheets 40 may be interposed. In this embodiment, a sheet 40 having a size substantially the same as or slightly smaller than the nail holding plate 27 and the back plate 28 is interposed.

  The sheet 40 is flexible and transparent, and has a rectangular shape that divides predetermined display portions such as a shielding portion 41 that restricts the display area of the liquid crystal display means 6 and a special symbol display portion 32 on the front or back surface thereof. A shape display frame 42, a hold display unit 43 for displaying the number of reserved changes in the special symbol 32 a and the like, and a decorative symbol (not shown) such as the character are displayed.

  The shield 41 is printed on the periphery of the sheet 40, such as outside the game area A, with opaque ink, paint, or the like. Decoration patterns such as the display frame 42 and characters are printed with semi-transparent or opaque ink, paint, or the like. The holding display unit 43 is printed with semi-transparent or opaque ink, paint, etc., except for a predetermined number of see-through parts 43a that can see through the liquid crystal display means 6 side, for example, and the start-up means 22 while the special symbol 32a is changing. , When the winning of the game ball is detected, the liquid crystal display means 6 emits light behind the fluoroscopy part 43a corresponding to the number of holds for the detected number, and the hold is displayed by the light emission of the fluoroscopy part 43a. ing.

  The seat 40 has an opening 44 in a portion corresponding to the game nail 26, a portion corresponding to a mounting hole for a predetermined game component such as the starting means 22, the big winning means 23, the normal winning means 24, the ball passing hole and the like. Each is formed. A hatched portion in FIG. 12 indicates a printed portion of the sheet 40.

  By interposing the other decorative sheet 40 between the adjacent plates 27, 28, and 30 in this way, the game board 16 has a decorative property and the like even though each of the plates 27, 28, and 30 is transparent. The sheet 40 can be protected by the plates 27, 28, and 30. Moreover, since it is sufficient that printing is performed on the flexible sheet 40, the printing can be facilitated as compared with printing on the plates 27, 28, and 30.

  As mentioned above, although each Example of this invention was explained in full detail, this invention is not limited to this Example, A various change is possible within the range which does not deviate from the meaning. For example, in the first embodiment, the game board 16 is constituted by the nail holding plate 27 and the back board 28, and in the second embodiment, the front board 33 is added thereto, but the game board 16 is composed of a plurality of board materials. What is necessary is just to comprise. Each plate material may be integrated by bonding or the like before the game nail 26 is inserted.

  What is necessary is just to determine the thickness of each board 27,28,33 suitably.
