Description

  The present invention relates to a gaming machine such as a pachinko machine.

  Conventionally, there is a pachinko machine, for example, as a representative example of a gaming machine. This pachinko machine includes a game board having a game area into which game balls are driven. In general, this game board is composed of a veneer board having a substantially rectangular shape in front view, a cell sheet attached to substantially the entire front surface of the veneer board, and a design representing a model of a pachinko machine, and the cell. A plurality of nails planted on the cell sheet surface side of the plywood sheet in a state where the sheet is pasted, and game parts such as various winning holes arranged on the cell sheet surface side. (For example, refer to Patent Document 1). The veneer plate is formed with a through-opening portion having a predetermined shape (hereinafter, referred to as an “opening portion for accessory installation” as appropriate) for attaching the above-described gaming parts by router processing.

In recent years, a cell sheet is bonded to the front side of the veneer board after router processing, and a transparent resin plate after router processing (router processing to form an opening for accessory installation) is placed on the front side of the veneer board. By doing so, it is conceivable to decorate the game area of the game board. Such a game board is manufactured by the following method. That is, the veneer plate and the transparent resin plate are router processed by the respective router processing machines so as to form the accessory installation opening. After that, the veneer plate and the transparent resin plate are fixed together and positioned and placed on the mounting table of the nailing machine, and a nail for giving behavior to the flow of the game ball is removed from the front side of the transparent resin plate by the nailing machine. It is a manufacturing method of hitting.
JP 2004-160258 A (page 5, FIG. 1)

However, the conventional example having such a configuration has the following problems.
That is, in the conventional pachinko machine, the transparent resin plate and the veneer plate are combined and fixed by a fixing member so that the both are positioned and fixed, and the boss (projection pin) of the mounting table of the nail driver is positioned on the plywood plate. The plywood and nailing machine are positioned by inserting them into the holes, but if the transparent resin plate and plywood are aligned and fixed with a fixing member, they are nailed into the positioning holes in the plywood. Even if the veneer plate and the nailing machine are positioned by inserting the boss of the mounting table of the machine, the nail driving position on the transparent resin plate is shifted from the planned position. As described above, when a nail is struck at a position deviated from the planned position on the transparent resin plate, the nail is not attached to the opening for installing the accessory in the router process performed before this nail driving process. There is a problem in that the positional relationship is not suitable and a game board in which nails are planted with high accuracy cannot be manufactured.

  In addition, the problem mentioned above is a problem which has arisen for the first time by providing a transparent resin plate. In other words, in a game board made of plywood without a transparent resin plate, the reference hole of the plywood is aligned with the router processing machine to perform router processing, and then the reference hole of the plywood is aligned with the nailing machine. Therefore, the reference hole of the plywood is commonly used as a positioning hole by the router processing machine and the nailing machine, and there is no displacement of the nail driving with respect to the opening for installing the accessory. On the other hand, in a game board composed of a transparent resin plate and a plywood plate, the alignment of the transparent resin plate and the plywood plate and the alignment of the plywood plate and the nailing machine may be performed in different parts. This is a problem that has arisen for the first time due to the presence of a plate material (transparent resin plate) other than the veneer plate.

Accordingly, a substantially central portion of the front surface portion of the game board 30 is exposed to the front surface side of the inner frame 12 through the window hole 21 of the resin base 20. Further, two glasses 137 (see FIG. 2) are attached to the window hole 21 at a predetermined interval in the front and rear (double glass structure).

  Next, the configuration of the game board 30 will be described with reference to FIG. FIG. 4 is a front view showing the configuration of the game board 30. The game board 30 includes a general winning port 31, a variable winning device 32, a first starting port 33 (for example, an operation chucker), a second starting port 34 (for example, a through gate), a variable display unit 35, and the like. The general winning port 31, the variable winning device 32, the first starting port 33, the second starting port 34, the variable display unit 35 and the like are respectively provided in the through holes formed by the router processing in the game board 30. The game board 30 is attached from the front side with a wood screw or the like. A game ball enters the above-described general winning opening 31, variable winning device 32, and first start opening 33, and the winning balls are detected switches (winning opening switch (not shown), count switch (not shown), And a predetermined number of prize balls are paid out to the upper plate 19 (or the lower plate 15) based on the output of the detection switch. In addition, the game board 30 is provided with an out port 36, and game balls that have not entered the various winning devices etc. are guided through the out port 36 to a ball discharge path (not shown). It has become. A number of nails are planted on the game board 30 in order to appropriately disperse and adjust the falling direction of the game balls, and various members (acts) such as the windmill 37 are arranged.

  The variable display unit 35 has a first symbol display device 42 for variably displaying a first symbol (for example, a special symbol) as identification information with a winning at the first starting port 33 as a trigger, and a second starting port 34. And a second symbol display device 41 for variably displaying a second symbol (for example, a normal symbol).

  The second symbol display device 41 has a second symbol display unit 43 and a holding lamp 44, and each time a game ball passes through the second starting port 34, for example, a display symbol (ordinary symbol) by the display unit 43 is displayed. The first start port 33 is configured to be in an activated state (opened) for a predetermined time when the fluctuation display stops at a predetermined symbol. The number of times that the game ball has passed through the second start opening 34 is held up to a maximum of 4 times, and the number of times the game ball is held is lighted and displayed by the hold lamp 44. The display unit 43 may be configured to be variably displayed by a part of the first symbol display device 42 (liquid crystal display device) in addition to the configuration to be variably displayed by switching lighting of a plurality of lamps. . Similarly, the hold lamp 44 may be configured to be variably displayed on a part of the first symbol display device 42. The second symbol display device 41 described above corresponds to the normal identification information fluctuation display means in the present invention.

  The first symbol display device 42 is configured as a liquid crystal display device, and the display content is controlled by a display control device 45 described later. The first symbol display device 42 displays, for example, three symbol rows of left, middle and right. Each symbol row is composed of a plurality of symbols, and these symbols are variably displayed on the first symbol display device 42 so as to be scrolled for each symbol row. In the present embodiment, the first symbol display device 42 (liquid crystal display device) is provided with a large 9.5 inch size liquid crystal display, for example. The variable display device unit 35 is provided with a center frame 47 so as to surround the first symbol display device 42. The first symbol display device 42 described above corresponds to the identification information fluctuation display means in the present invention, and the display control device 45 described above corresponds to the display control means in the present invention.

  The variable winning device 32 is normally in a closed state in which a game ball cannot be won or difficult to win, and is repeatedly operated between an open state in which a game ball is easy to win and a normal closed state in a big win. ing. More specifically, when a game ball wins the first starting port 33, the symbols are displayed in a variable manner on the first symbol display device 42, and the final symbol after the stop becomes a combination of specific symbols set in advance. A special gaming state occurs. The large winning opening 32a of the variable winning device 32 is in a predetermined open state, so that the game ball is likely to win a prize (a big hit state). Specifically, the passage of a predetermined time or a predetermined number of winnings is regarded as one round, and the big winning opening 32a of the variable winning device 32 is repeatedly opened a predetermined number of times. The number of times that the game ball has passed through the first start port 33 is held up to a maximum of 4 times, and the number of times that the game ball is held is lit and displayed by the hold lamp 46. Note that the hold lamp 46 may be configured so as to be variably displayed on a part of the first symbol display device 42.

  Further, the game board 30 is provided with a rail unit 50 for guiding the game ball launched from the game ball launching device 38 to the upper part of the game board 30, and is launched in accordance with the turning operation of the game ball launch handle 18. The played game balls are guided to a predetermined game area through the rail unit 50. The rail unit 50 is formed of a ring-shaped resin molded product (for example, a molded product added with fluororesin), and has an inner rail 51 and an outer rail 52 that are integrally formed in an inner and outer double. .

  A return ball preventing member 53 is attached to the tip portion of the inner rail 51 (the upper left portion in FIG. 4). This prevents a situation in which the game ball once guided from the ball guide path between the inner rail 51 and the outer rail 52 to the upper part of the game board 30 returns to the ball guide path again. Yes. Further, a return rubber 54 is attached to the outer rail 52 at a position corresponding to the maximum flight portion of the game ball (upper right portion in FIG. 4: a portion corresponding to the tip portion of the outer rail 52). Therefore, the game ball fired at a predetermined momentum or more hits the return rubber 54 and is bounced back. On the inner surface of the outer rail 52, there is a sliding plate 55 as a long metal strip made of stainless steel in order to make the flight of the game ball smoother, that is, to reduce the frictional resistance of the game ball. It is attached.

  A convex portion 57 is formed at the entrance of the ball guide passage between the inner rail 51 and the outer rail 52 so as to close a part of the ball guide passage. The convex portion 57 is provided in a substantially vertical direction from the inner rail 51 to the lower end portion of the rail unit 50, and a foul ball that does not reach the game area and flows backward in the ball guide passage is used as a foul ball passage 63 (see FIG. 3). Play a role in guiding. The lower right corner and the lower left corner of the game board 30 are spaces for sticking stickers (S1, S2 in FIG. 4) and plates such as stamps (for example, serial numbers are described). In order to secure this adhering space, notches 58 and 59 are formed in the flange 56. By sticking a sticker such as a certificate (S1, S2 in FIG. 4) to the lower right corner or the lower left corner of the game board 30, the game board 30 and the certificate can be uniquely defined.

  Next, the game area will be described. The game area is partitioned and formed in a substantially circular shape by the inner peripheral part (inner and outer rails) of the rail unit 50. In particular, in the present embodiment, the game area partitioned on the board surface of the game board 30 is much more than conventional. It is composed largely. In the present embodiment, the distance between the uppermost point of the outer rail 52 and the lower part of the game board 30 is 445 mm (58 mm longer than the conventional product), and is from the extreme left position of the outer rail 52 to the extreme right position of the inner rail 51. The distance is 435 mm (50 mm longer than the conventional product). The distance from the extreme left position of the inner rail 51 to the extreme right position of the inner rail 51 is 418 mm.

  In addition, the 2nd starting port 34 located in the both sides of the variable display apparatus unit 35 has a guide mechanism in which the game ball which passed this 2nd starting port 34 is approached toward the center. Thereby, even when the game area is expanded in the left-right direction, the game ball can be guided toward the center first start port 33 and the variable prize-winning device 32. By expanding, it is possible to suppress a decrease in interest due to difficulty in winning game balls. Furthermore, by extending the game area in the left-right direction, various arrangements of the windmill 37, the second start port 34, a plurality of nails (guide nails for guiding the game ball to the center), and other accessories are arranged. Thus, the behavior of the game ball in the game areas on the left and right sides of the variable display device unit 35 can be made more interesting. In addition, since the game area is also expanded in the vertical direction, various windmills 37, second start ports 34, a plurality of nails, and other accessories can be further arranged in the vertical direction in the game area. The behavior of the game ball can be made even more interesting.

  Returning to the description of FIG. 3, in the resin base 20, below the window hole 21 (game board 30), a launch rail 61 for guiding the game ball immediately after being launched from the game ball launcher 38 is attached. ing. The launch rail 61 is fixedly attached to the resin base 20 via a metal plate 62 behind the launch rail 61, and is configured to extend linearly at a predetermined launch angle (launch angle). Accordingly, the game ball launched by the turning operation of the game ball launching handle 18 is first launched obliquely upward along the launch rail 61, and then into the predetermined game area through the ball guide path of the rail unit 50 as described above. Guided.

  In the case of this pachinko machine 10, the game area is greatly expanded compared to the conventional case, and under such a configuration, the curvature of the guide rail has to be reduced, and thus a device for stabilizing the launch ball is required. . Therefore, in the present embodiment, the launch position of the game ball is lowered and the inclination angle (launch angle) of the launch rail 61 is made somewhat larger than that of the existing one (that is, the launch rail 61 is raised) to further launch. The length of the rail 61 is made longer than that of the existing one so as to ensure a sufficiently long ball guiding distance. Thereby, the game ball launched from the game ball launcher 38 can be guided to the guide rail in a more stable state. In this case, in particular, the launch rail 61 is formed to extend from the launch position of the game ball launcher 38 to a position beyond the center position (out port 36) of the game area.

  Further, there is a gap of a predetermined interval between the firing rail 61 and the rail unit 50 (guidance rail), and a foul ball passage 63 is formed below the gap. Therefore, if the game ball launched from the game ball launching device 38 does not reach the return ball prevention member 53 and returns to the inside of the guide rail as a foul ball, the foul ball passes through the foul ball passage 63 to the lower plate. 15 is discharged. Incidentally, in the case of the present embodiment, the length of the firing rail 61 is about 240 mm, and the length of the gap at the tip of the firing rail (the length on the extension line of the firing rail 61) is about 40 mm.

  When the foul spheres flow backward in the guide rail, most of them flow along the outer rail 52 and drop downward when reaching the lower end of the outer rail 52. However, some foul spheres fall inside the guide rail. There is also a thing that jumps to the inner rail 51 side. At this time, the splashed foul ball hits the convex portion 57 at the entrance of the ball guide passage and is guided to the foul ball passage 63. Thereby, all of the foul balls are surely guided to the foul ball passage 63. This suppresses interference between the foul ball and the next game ball to be launched.

  Although detailed disclosure of the drawings is omitted, game balls are supplied to the game ball launcher 38 one by one from the ball outlet on the front frame set 14 side (the ball outlet leading from the most downstream portion of the upper plate 19). . At this time, since the launch position of the game ball is lowered in the present embodiment, the drop from the exit of the ball on the front frame set 14 side to the launch position becomes large, but in the vicinity of the base end portion of the launch rail 61, its right side and Guide members 65 and 66 were installed on the front side. Thereby, the game ball supplied from the ball exit on the front frame set 14 side is always set at a predetermined launch position, and a stable launch operation can be realized. Further, the game ball launching device 38 is provided with a ball striking ball, and a game ball is launched with the rotation of the ball striking center around the shaft portion. Therefore, while aiming to reduce the weight of the hitting ball by changing the material to light metal such as aluminum and reducing the size of the shaft, the head portion of the hitting ball (on the side opposite to the shaft) is secured to ensure sufficient firing force. A weight is provided at the end. Thereby, sufficient and stable launch of the game ball can be realized. By providing the weight portion of the hitting ball projecting upward, it is possible to easily pick or hit the hitting ball, and it is easy to adjust the hitting strength of the hitting tip.

  In addition, the code | symbol 67 in FIG. 3 is the discharge port connected to the upper plate 19, and a game ball is discharged to the upper plate 19 through this discharge port 67. FIG. The discharge port 67 is provided with an openable / closable shutter 68 that is displaced between a substantially horizontal state and a substantially vertical state about a rotation axis in a substantially horizontal direction. When the front frame set 14 is released from the inner frame 12 (the state shown in FIG. 3), the shutter 68 is changed from a substantially horizontal state to a substantially vertical state by an urging force of a spring or the like. The discharge port 67 is closed. When the front frame set 14 is closed, the shutter 68 is pushed open by a ball passage rod 69 (see FIG. 2) provided on the back surface of the front frame set 14 to be in a substantially horizontal state. The game ball discharged toward the direction passes through the ball passage rod 69 and is discharged to the upper plate 19 without any leakage. Therefore, in the pachinko machine 10 in which the front decorative frame is omitted and the upper plate 19 is directly provided to the front frame set 14, the game balls in the payout passage and the like are outside the pachinko machine 10 when the front frame set 14 is opened. Inconveniences such as spilling out can be prevented.

  As shown in FIG. 3, the resin base 20 is provided with a substantially rectangular small window 71 at the lower right portion of the window hole 21. Therefore, a sticker such as a stamp (S1 in FIG. 4) stretched at the lower right corner of the game board 30 can be seen through the small window 71. Further, a sticker or the like can be attached from the small window 71.

  As shown in FIG. 3, support brackets 81 and 82 are attached to the left end portion of the inner frame 12 as a support mechanism for the front frame set 14. The upper support fitting 81 is provided with a support hole 83 having a notch on the front side of the figure, and the lower support fitting 82 is provided with a protruding shaft 84 protruding in the vertical direction.

  As shown in FIG. 3, a front frame set open detection switch 90 that detects that the front frame set 14 is opened with respect to the inner frame 12 is provided above the inner frame 12. When the front frame set 14 is opened, it is output from the front frame set open detection switch 90 to the computer for the hall (in the pachinko parlor).

  The front frame set 14 is provided with light emitting means such as various lamps around it (for example, a corner portion). These light emitting means play a role of enhancing the effect of the game during the game by changing and controlling the light emission mode such as lighting and blinking according to the change of the game state at the time of big hit or predetermined reach. For example, on the periphery of the window portion 101, an annular illumination portion 102 containing a light emitting means such as an LED (light emitting diode) is provided symmetrically. In the upper part, a central illumination part 103 is also provided, which also incorporates light emitting means such as LEDs. In the pachinko machine 10, the central illumination unit 103 functions as a jackpot lamp, and lights and blinks when the jackpot is informed that the jackpot is being hit. Further, the upper plate 19 is also provided around the upper plate 19 with an upper plate illumination unit 104 having a built-in light emitting means such as an LED. In addition, on the left and right sides of the central illumination unit 103, there are provided a prize ball lamp 105 that is lit during the payout of a prize ball and an error display lamp 106 that is lit when a predetermined error occurs. In addition, a small window 107 made of a transparent resin is provided so as to be adjacent to the lower end portion of the annular illumination portion 102 so that a part of the inner frame 12 surface, the game board 30 surface, or the like can be visually recognized. Since the predetermined portion of the small window 107 is flat, the certificate paper or the like attached to the lower right corner of the game board 30 can be suitably read from the flat portion of the small window 107 by a machine.

  In addition, a ball lending operation unit 120 is disposed below the window unit 101, and the ball lending operation unit 120 is provided with a ball lending button 121, a return button 122, and a frequency display unit 123. When the ball lending operation unit 120 is operated with a bill or a card inserted in a card unit (ball lending unit) (not shown) arranged on the side of the pachinko machine 10, a game ball is lent according to the operation. Done. The ball lending button 121 is operated to obtain a lending ball based on information recorded on a card or the like (recording medium), and the lending ball is supplied to the upper plate 19 as long as there is a remaining amount on the card or the like. Is done. The return button 122 is operated when requesting the return of a card or the like inserted into the card unit. The frequency display unit 123 displays remaining amount information such as a card. It should be noted that the ball rental operation unit 120 is not necessary for a pachinko machine in which game balls are lent directly to the upper plate from a ball lending device or the like without using a card unit, that is, a so-called cash machine. Therefore, a decorative seal or the like is attached to the installation portion of the ball rental operation unit 120. Thereby, the common use of the lending operation unit of the pachinko machine using the card unit and the cash machine can be achieved.

  In addition, on the back side of the game board 30, a winning detection mechanism for detecting the passage of gaming balls such as various winning holes is provided. Specifically, a prize opening switch (not shown) is provided at a position corresponding to the general prize opening 31 on the front side of the game board 30, and the variable prize winning device 32 is provided with a count switch (not shown). The count switch is a switch for counting winning balls. An operation port switch 224 is provided at a position corresponding to the first start port 33, and a gate switch (not shown) is provided at a position corresponding to the second start port 34. The operating port switch 224 described above corresponds to a winning detection means in the present invention.

  A prize opening switch (not shown) and a gate switch (not shown) are connected to a board relay board (not shown) through electrical wiring (not shown), and this board relay board (not shown) is a main board (main control device) to be described later. 261). Further, the count switch (not shown) is connected to a special winning opening relay board (not shown), and this special winning opening relay board (not shown) is also connected to the main board. On the other hand, the operation port switch 224 is directly connected to the main board without passing through the relay board.

  Although not shown in the drawings, the variable winning device 32 is provided with a large winning port solenoid for opening the large winning port 32a, and the first starting port 33 is an operating port for opening the electric accessory. A solenoid is provided.

  The detection results detected by the winning detection mechanism are taken into a main board, which will be described later, and a payout command (the number of game balls to be paid out) corresponding to the winning situation is transmitted from the main board to the payout control board. The Then, a predetermined number of game balls are paid out by the output of the payout control board. In such a case, a conventional method (so-called evidence ball method) in which game balls won at various winning openings are once collected in a winning ball processing device, and the winning ball processing device confirms the presence of the winning balls one by one and then pays out one by one. Unlike the above, the pachinko machine 10 according to the present embodiment electrically senses the winning of a game ball at each winning opening and immediately pays out (that is, the pachinko machine 10 abolishes the winning ball processing device). is doing). Therefore, even if there are a lot of game balls to be paid out, the payout can be carried out quickly. However, the conventional “evidence ball system” may be applied to the present invention.

  Next, the electrical configuration of the pachinko machine 10 will be described with reference to FIG. FIG. 5 is a block diagram showing the electrical configuration of the pachinko machine 10. The pachinko machine 10 includes a main control device 261, a payout control device 311, a launch control device 312, a display control device 45, a power supply device 313, and the like.

  By the way, in the first symbol display device (liquid crystal display device) 42, as shown in FIG. 6, three symbol rows U, M, and D of upper, middle, and lower are set. For each D, three symbols (the first symbol: for example, a special symbol) of the left symbol, the middle symbol, and the right symbol are variably displayed in the horizontal direction. In the present embodiment, a series of symbols is composed of a main symbol SZ made of a picture such as a marine creature and a sub-design FZ made of a shell-shaped picture, each of which is numbered “0” to “9”. The main symbols SZ are displayed in ascending numerical order, and the sub symbols FZ are arranged between the main symbols SZ to form a series of symbol rows U, M, and D. The main symbol SZ and the sub symbol FZ are variably displayed from right to left with periodicity.

  In such a case, in the upper symbol row U and the middle symbol row M, the series of symbols is displayed in ascending order (that is, in the order of increasing the number of the main symbol SZ), and in the lower symbol row D, the series of symbols is in descending order (that is, , In order of decreasing the number of the main symbol SZ). Based on the winning at the first starting port 33, a series of variable display of the symbol sequence U, M, D is started, and the variable symbol display is performed in the order of the upper symbol column U → the lower symbol column D → the middle symbol column M.

  That is, the value (first random number) of the big hit random number counter C1 in the first random number generator (not shown) at the timing of detecting the winning of the game ball by the operation port switch 224 provided in the first start port 33. It is stored in a reserved ball storage area (a first random number storage unit not shown) of the RAM 503. When the probability is low, the first determination unit (not shown) determines that the value of the big hit random number counter C1 (first random number) stored in the first random number storage unit (not shown) is two values “337, If it is “673”, it is determined that it is a big hit, otherwise it is determined that it is off. When the probability is high (also referred to as probability variation), the first determination unit (not shown) uses the value (first random number) of the big hit random number counter C1 stored in the first random number storage unit (not shown). Ten values “67, 131, 199, 289, 337, 401, 463, 523, 601, 661” are determined to be big hits, otherwise they are determined to be off. The first random number generation unit (not shown) and the first determination unit (not shown) described above are realized by causing the CPU 501 to execute a predetermined program.

  When the CPU 501 determines that the value of the big hit random number counter C1 is a win value, the main control device 261 outputs a signal for setting the special gaming state to the variable winning device 32. Based on the instruction from the main controller 261, the variable winning device 32 executes a jackpot operation in which the game ball is repeatedly operated in an open state and a normal closed state where the game ball is easy to win.

A transparent resin plate 400 that is transparent to the veneer plate 420 so as to cover at least the game area of the veneer plate 420 on the front side of the veneer plate 420, and the transparent resin plate 400 is superimposed on the veneer plate 420. In this state, a nail 430 for changing the behavior of a game ball flowing down the game area is fixed by hitting from the front side of the transparent resin plate 400, and the transparent resin plate 400 is an accessory (center frame 47 or A transparent resin plate 400 that performs router processing to form an accessory installation opening 401 that is an opening of a game area for installing the first start opening 33 and the like) A concave portion that fits both the first convex portion 450 as the positioning portion of the router processing machine and the second convex portion 460 as the positioning portion of the nail driving machine for driving the nail 430, and both fitting axes. The plywood plate 420 has a projection 403 having a common fitting recess 402 having the same axis as the axis, and the plywood plate 420 serves as a positioning unit of a router machine for the plywood plate 420 for performing the router machining for forming the accessory installation opening 421. Since it is a fitting hole that fits both the three convex portions 470 and the protrusion 403 of the transparent resin plate 400, and has a common fitting hole 422 that has both fitting axes as the same axis, The transparent resin plate 400 has an opening for installing an accessory in a state where the first convex portion 450 as the positioning portion of the router processing machine for the transparent resin plate 400 is fitted into the common fitting concave portion 402 of the transparent resin plate 400. Router adder forming part 401 It is performed by the router machine for the transparent resin plate 400. Further, the transparent resin plate 400 is in a state of being fitted to the plywood plate 420 so that the projection 403 is fitted into the common fitting hole 422 of the plywood plate 420, and a second convex portion as a positioning unit of the nail driver Since the nail is driven to the front side of the transparent resin plate 400 by the nailing machine in a state where 460 is fitted to the common fitting recess 402 of the transparent resin plate 400 through the common fitting hole 422 of the plywood plate 420, The alignment reference axis of the router processing machine for the transparent resin plate 400 and the alignment reference axis of the nailing machine can be the same axis. That is, both the reference axes can be made the same as the fitting axis of the common fitting recess 402 in the transparent resin plate 400 to perform router processing and nailing of the transparent resin plate 400. Deviation in the positional relationship between the opening 401 for use and the nail 430 can be reduced.

  Further, the veneer plate 420 forms an accessory installation opening 421 in a state where the third convex portion 470 as a positioning portion of the router processing machine for the veneer plate 420 is fitted into the common fitting hole 422 of the veneer plate 420. The router processing is performed by a router processing machine for the plywood plate 420, and in the state in which the projection 403 of the transparent resin plate 400 is fitted in the common fitting hole 422, as described above, it is transparent by the nailing machine. Since the nail is nailed to the front side of the resin plate 400, the alignment reference axis of the router processing machine for the plywood plate 420 and the fitting axis of the common fitting recess 402 serving as the reference axis of the transparent resin plate 400 are the same axis. It can be. That is, both the reference shafts can be made the same as the fitting axis of the common fitting hole 422 in the plywood plate 420, and the plywood plate 420 can be processed by the router and nailed to the front side of the transparent resin plate 400. A shift in the positional relationship between the accessory installation opening 421 and the nail 430 toward the front surface of the transparent resin plate 400 can also be reduced.

  As a result, the positional relationship of the nail 430 with respect to the accessory installation opening in the router processing step performed before the nail driving step can be made appropriate, and the nail 430 is planted with high accuracy. The game board 30 can be manufactured, and the pachinko machine 10 having the game board 30 in which the nails 430 are planted with high accuracy can be provided.

  Further, since the protrusion 403 of the transparent resin plate 400 has a protrusion height smaller than the thickness of the plywood plate 420, the protrusion 403 of the transparent resin plate 400 is fitted into the common fitting hole 422 of the plywood plate 420. In this state, the protrusions 403 of the transparent resin plate 400 do not get in the way without protruding from the back side of the plywood plate 420 and staying within the thickness of the plywood plate 420. That is, when the protruding portion 403 of the transparent resin plate 400 protrudes outside from the back surface side of the veneer plate 420, the portion that is exposed to the outside gets in the way and processing such as deleting it is necessary. Since the protruding portion 403 of the transparent resin plate 400 remains within the thickness of the plywood plate 420, it does not get in the way and the above-described deletion processing can be made unnecessary.

  In addition, since a plurality of sets (two sets in this embodiment) of the protrusions 403 of the transparent resin plate 400 and the common fitting holes 422 of the plywood plate 420 are provided, router processing for the transparent resin plate 400 is performed. The first convex portion 450 as a plurality of (two) positioning portions of the machine and the common fitting concave portion 402 of the plurality of projecting portions 403 of the transparent resin plate 400 that are in a corresponding positional relationship are fitted. Thus, positioning of the transparent resin plate 400 during router processing can be performed with high accuracy. Further, by fitting the third convex portion 470 as the two positioning portions of the router processing machine for the plywood plate 420 and the two common fitting holes 422 of the plywood plate 420 in a corresponding positional relationship with each other. Positioning of the plywood plate 420 during router processing can be performed with high accuracy. Further, by fitting the two projecting portions 403 of the transparent resin plate 400 and the two common fitting holes 422 of the veneer plate 420 corresponding to the projections 403, the transparent resin plate 400 and the veneer plate 420 are Both can be positioned with high accuracy at the time of overlapping. In addition, the two common fitting holes 422 of the plywood plate 420 overlapped with the transparent resin plate 400 in this way, and the second convex portion 460 as the two positioning portions of the nail driver in the corresponding positional relationship. Can be positioned with high accuracy when nailing the plywood plate 420 in a state of being superimposed on the transparent resin plate 400.

  Further, in the case where the projection 403 of the transparent resin plate 400 and the common fitting hole 422 of the plywood plate 420 are made into one set and a plurality of sets are provided, the distance between the projections 403 is slightly shifted. Even in this case, it is possible to allow displacement between the protrusions 403 of the transparent resin plate 400, and the transparent resin plate 400 and the plywood plate 420 can be overlapped.

  The cell sheet 410 has a display for representing a pachinko machine or a display for decorating a game area, and is separate from the transparent resin plate 400 and the veneer plate 420, and is on the front side of the transparent resin plate 400. Since the transparent resin plate 400 and the cell sheet 410 are in close contact with each other, the transparent resin plate 400 and the cell sheet 410 are adhered to each other on the back side of the transparent resin plate 400 so as to be visible from the back side. . That is, by simply aligning the cell sheet 410 with the back surface side of the transparent resin plate 400, at least a part of the cell sheet 410 is separated from the back surface side of the transparent resin plate 400, and the cell sheet is placed on the back surface side of the transparent resin plate 400. In this case, when the game board 30 is viewed from the front, the display of the separated portion is blurred (the light to the transparent resin plate 400 is separated by the separated portion and the close contact portion of the cell sheet 410). However, according to the present embodiment, such a problem can be solved. That is, the transparent resin plate 400 and the cell sheet 410 are in close contact with each other, and there is no part where the cell sheet 410 is separated on the back surface side of the transparent resin plate 400. .

  Further, between the transparent resin plate 400 and the plywood plate 420, a display portion for displaying the model name of the pachinko machine 10 as a display for representing the gaming machine, and a feature (or individuality) of the model for decorating the gaming area. ) Is provided with the cell sheet 410 on which the display portion to be decorated is drawn (printed), so that the game ball flows down on the front side of the transparent resin plate 400 and the transparent resin plate 400 on the opposite side thereof. The cell sheet 410 is positioned on the back surface side of the transparent resin plate 400, and the cell sheet 410 provided on the back surface side of the transparent resin plate 400 is not contacted with the game ball, and the cell sheet 410 can be protected. .

  The game board 30 is obtained by superposing a transparent resin plate 400 on the front side of the plywood plate 420 to which the nail 430 is driven and fixed to the front side. The nail 430 is placed on the front side of the plywood plate 420 with the transparent resin plate 400. In the state of being stacked, the transparent resin plate 400 penetrates the transparent resin plate 400 and is struck to the plywood plate 420. The nail 430 in this struck state contacts the transparent resin plate 400 and the plywood plate 420. Since the transparent resin plate 400 and the plywood plate 420 are fixed by the nail 430, a dedicated fixing tool for fixing the transparent resin plate 400 and the plywood plate 420 can be eliminated, and the number of parts can be reduced. be able to.

  Moreover, since the transparent resin plate 400 is a transparent thin plate-like member made of a transparent resin, a transparent thin plate-like member can be suitably manufactured by using the transparent resin.

  Next, the pachinko machine 10 according to the second embodiment will be described with reference to FIG. FIG. 12 is a view showing a path formation process before the nail driving process for the game board 30 of the second embodiment.

  In the manufacturing process of the game board 30 according to the second embodiment, the nail driving process is performed after the passage hole forming process, which is different from the first embodiment. In addition, description is abbreviate | omitted about the content similar to the above-mentioned Example 1, and suppose that it explains in detail about a passage formation process below.

  The process until the superposition process of the transparent resin plate 400 and the plywood plate 420 is completed is the same as that of the first embodiment, and will be described below after the superposition process is completed.

  As shown in FIG. 12, the veneer plate 420 on which the transparent resin plate 400 is overlaid in the overlapping step is placed on the mounting table TB3 (table) of the nailing machine, and the protruding portion of the transparent resin plate 400 It is assumed that the second convex portion 460 as the positioning portion of the nailing machine is fitted to the common fitting concave portion 402 of 403.

  Specifically, the two second convex portions 460 (positioning bosses and projecting pins) arranged at intervals on the surface of the mounting table TB3 of the nailing machine correspond to the second convex portions 460. The veneer plate 420 on which the transparent resin plates 400 are overlapped is placed on the mounting table of the nail driver so as to be fitted into the common fitting recesses 402 of the two projections 403 of the transparent resin plate 400.

  The nailing machine is provided with a drilling function (for example, drilling with a drill), and a hole 404 is made in advance at a predetermined position of the transparent resin plate 400 where the nail 430 is to be driven by the nailing machine. That is, as shown in FIG. 12, in the state where the veneer plate 420 on which the transparent resin plate 400 is overlapped in the overlapping step is placed on the mounting table TB3 of the nailing machine, the nail 430 is tried to be driven by the nailing machine. A passage formation process is performed in which a passage 404 is opened by a drill at a predetermined portion of the transparent resin plate 400. As shown in FIG. 12, the passage hole 404 has a diameter r2 smaller than the diameter r1 of the trunk of the nail 430.

  The nail driving process of the first embodiment is subsequently performed by a nail driver after the road hole forming process. That is, the nail 430 is driven to a predetermined position by the nail driver, and the nail 430 is driven so that the nail tip reaches the plywood plate 420 through the transparent resin plate 400.

  As described above, according to the pachinko machine 10 according to the second embodiment, the nail 430 can be driven with a force smaller than the nail driving force according to the first embodiment, and the nail 430 can be mounted on the mounting table of the nail driving machine. Since the passage hole forming step and the nail driving step are performed while left in place, it is possible to reduce the shift between the passage hole 404 and the nail driving portion.

  Next, a pachinko machine 10 according to a third embodiment will be described with reference to FIGS. FIG. 13 is a cross-sectional view of a main portion of the game board 30 according to the third embodiment. FIG. 14 is a cross-sectional view of the main part showing the configuration of the positioning unit of the router processing machine for the transparent resin plate 400 in a state where the transparent resin plate 400 in Example 3 is positioned on the mounting table TB2. FIG. 15 is a main part sectional view showing a configuration of a positioning unit of a router processing machine for the plywood plate 420 in a state where the plywood plate 420 in the third embodiment is positioned on the mounting table TB1. FIG. 16 is a cross-sectional view of the main part showing the configuration of the positioning unit of the nailing machine in a state where the veneer plate 420 on which the transparent resin plate 400 is superimposed is positioned on the mounting table TB3.

  In the gaming board 30 of the above-described first embodiment, the common fitting concave portion 402 as the common fitting portion is provided in the protrusion 403 of the transparent resin plate 400. The game board 30 of Example 3 is mainly different from Example 1 described above in that a common fitting convex part 405 as a common fitting part is provided on the protrusion 403 of the transparent resin plate 400. In addition, description is abbreviate | omitted about the content similar to the above-mentioned Example 1, and suppose that the common fitting convex part 405 etc. of the projection part 403 of the transparent resin board 400 are demonstrated in detail below.

  Since the common fitting convex portion 405 is adopted instead of the common fitting concave portion 402 of the projection 403 of the transparent resin plate 400 as described above, naturally, in the third embodiment, the above-described embodiments are used. 1, the first concave portion 452 is employed instead of the first convex portion 450 as the positioning portion of the router processing machine for the transparent resin plate 400, and the second as the positioning portion of the nailing machine in the first embodiment described above. A second concave portion 462 is employed instead of the convex portion 460.

  As shown in FIGS. 14 and 16, the protrusion 403 of the transparent resin plate 400 is the first positioning portion of the router processing machine for the transparent resin plate 400 that performs the router processing for forming the accessory installation opening 401. A convex portion as a fitting portion that fits into both a concave portion 452 (see FIG. 14) and a second concave portion 462 (see FIG. 16) as a positioning portion of a nailing machine to be described later for driving the nail 430, A common fitting convex portion 405 having both fitting axes as the same axis is provided. As shown in FIG. 7, the protrusions 403 are provided at two locations on the back side of the transparent resin plate 400, that is, the upper right and the lower left as viewed from the back, as in the first embodiment. Since the transparent resin plate 400 is a resin molded product, the protrusions 403 described above can be integrally molded.

  Further, as shown in FIG. 15, the common fitting hole 422 (through hole) of the plywood plate 420 is a first positioning portion of a router processing machine for the plywood plate 420 that performs the router processing for forming the accessory installation opening 421. This is a fitting hole that fits into both the three convex portions 470 and the protruding portion 403 of the transparent resin plate 400, and has both fitting axes as the same axis. As shown in FIG. 7, the common fitting hole 422 is formed at each of the plywood plates 420 corresponding to the two protrusions 403 of the transparent resin plate 400, as shown in FIG. It is provided in two places, upper left and lower right, in a state where 420 is viewed from the front. The common fitting hole 422 is formed in a cylindrical through-hole shape by router processing with a router processing machine for the plywood plate 420, for example.

  As shown in FIGS. 13 and 16, the protrusion 403 of the transparent resin plate 400 has a two-stage truncated cone shape in which a second truncated cone smaller than the first truncated cone is coupled. Specifically, the protrusion 403 has a shape in which a first truncated cone and a second truncated cone having a bottom surface having the same area as the upper surface are coupled to an upper surface of the first truncated cone on the tapered side. Thus, since the projection part 403 is provided with the 1st truncated cone, it is trapezoid shape (taper shape) in the state seen in the cross section. Further, as shown in FIG. 13, the protrusion 403 has a protrusion height smaller than the thickness of the plywood plate 420. That is, in a state where the transparent resin plate 400 is attached to the plywood plate 420, the protruding portion 403 of the transparent resin plate 400 does not protrude outside from the common fitting hole 422 of the plywood plate 420.

  Except for the difference in the configuration described above, the game board 30 is manufactured by the manufacturing method described in the first embodiment.

  As described above, according to the pachinko machine 10 of the third embodiment, the common fitting portion of the protrusion 403 of the transparent resin plate 400 is a router processing machine that performs router processing for forming the accessory installation opening 401. A convex part that fits both the first concave part 452 that is a positioning part and the second concave part 462 that is a positioning part of a nailing machine for driving a nail, and has both fitting axes as the same axis. Since the fitting convex portion 405 is used, even when the shared fitting portion is the common fitting convex portion 405 described above, the same effect as in the first embodiment is obtained.

  Next, a pachinko machine 10 according to a fourth embodiment will be described with reference to FIG. FIG. 17 is a partial cross-sectional view showing a portion of the protrusion 403 in the game board 30 of the fourth embodiment.

  In the gaming board 30 of the fourth embodiment, the portion of the projection 403 on the gaming board 30 is used as the visual recognition section 480, and the predetermined position on the back side can be visually confirmed through the visual recognition section 480. 1 to 3 are different. In addition, description is abbreviate | omitted about the content similar to the above-mentioned Examples 1-3, and suppose that the part of the projection part 403 of the game board 30 is demonstrated in detail below.

  As shown in FIG. 17, the main control board 491 (main board) of the main control device 261 as a control means for performing predetermined control of the game is encapsulated in a corresponding portion of the protrusion 403 on the back side of the plywood board 420. A caulking portion 495 for sealing the storage case 492 is positioned.

  Specifically, the main control board 491 is mounted with electrical components such as various ICs such as the CPU 501, the ROM 502, and the RAM 503 shown in FIG. The storage case 492 includes a bottomed box-like container 493 and a lid portion 494. The main control board 491 is attached to a predetermined position in the bottomed box-like container 493, and the lid portion 494 covers the storage case 492. Thus, the main control board 491 cannot be contacted from the outside. A caulking portion 495 is formed on one end side of the storage case 492. By caulking the caulking portion 495, the storage case 492 can be sealed. If the caulking portion 495 is not destroyed, the storage case The seal 492 cannot be released.

  As shown in FIG. 17, the transparent resin plate 400 is a transparent member, and a cell sheet 410 is affixed to a portion other than the protruding portion 403, and the veneer plate 420 to which the protruding portion 403 of the transparent resin plate 400 is fitted. Since the common fitting hole 422 is a through hole, when the gaming board 30 is viewed from the front, the portion of the common fitting hole 422 of the gaming board 30 becomes a visual recognition part 480 through which the back side of the gaming board 30 can be seen. ing. Since the storage case 492 is installed on the back side of the game board 30 so that the caulking part 495 is located at the place where the visual recognition part 480 exists, the back side of the game board 30 passes through the visual recognition part 480 from the front side of the game board 30. A crimped portion 495 can be seen.

  The above-described main control board 491 corresponds to the control means in the present invention, the above-described storage case 492 corresponds to the enclosing means in the present invention, and the above-described caulking portion 495 corresponds to the sealing means in the present invention.
