Description

  The present invention relates to a game board forming method, and more particularly to a method of cutting a game board by adsorbing it to a mounting table.

  Conventionally, as a method of forming a game board provided in a gaming machine, a method of forming a game board by pouring molten resin melted by applying heat to a synthetic resin (so-called injection molding) is known. Yes.

  Here, the game board is provided with an attachment hole for attaching a game member such as a start winning device or a grand prize device, a nail pilot hole for attaching a nail for changing the flow direction of the game ball, and the like. . The game member is inserted into the mounting hole and attached to the game board using screws or the like, and the nail is attached to the game board by being screwed into the nail lower hole.

  The mounting hole, the nail hole, and the like are formed in the process of injection molding of a game board (a plate-shaped synthetic resin plate provided with a predetermined hole). Specifically, in the above-described injection molding, the molten resin is poured into a mold having a protruding portion at a position corresponding to the position where the mounting hole or the nail hole is provided on the game board, and the poured molten resin is While filling in parts other than a protrusion part, the filled molten resin is cooled. Thus, the game board provided with the attachment hole, the nail pilot hole, etc. is formed in the process of injection molding.

  However, if an attachment hole, a nail pilot hole, or the like is formed in the injection molding process, the flow of the molten resin is blocked by the protrusions provided in the mold, and slows down. Therefore, the time taken from the start of pouring the molten resin into the mold to the end of pouring into the mold is longer than before, and the molten resin previously poured into the mold is solidified and later poured into the mold. There is a difference between the timing at which the molten resin solidifies and stress is generated due to the difference in the timing at which the molten resin solidifies.Therefore, there is a problem that distortion, sink, warp, etc. of the game board occur. Arise.

  Therefore, in order to reduce the occurrence of distortion, sink, warp, etc. of the game board, a forming process for forming the shape of the game board, and a cutting for cutting the game board using a predetermined processing device to form a predetermined hole A method of executing a process (processing process) has been devised (see, for example, Patent Document 1).

  In the cutting process of Patent Document 1, as shown in FIG. 4 of Patent Document 1, after placing the game board on the mounting table, holes are formed in the game board using a cutting blade.

According to such a technique of Patent Document 1, it is possible to reduce the occurrence of distortion, sink, warpage, etc. of the game board as compared with the case where the mounting hole, the nail pilot hole, etc. are formed in the injection molding process.
JP 2005-312989 A

  Here, the cutting process of Patent Document 1 is performed after the game board is fixed to the mounting table in the process of fixing the game board (game board fixing process). Here, as a technique for fixing the game board to the mounting table, a technique of sucking and fixing the game board by a suction unit provided on the mounting table, and the like can be mentioned.

  However, a game board made of a member such as a synthetic resin may cause minute distortions, sink marks, warpage, or the like during the formation process due to the characteristics of the synthetic resin.

  In this case, since the suction surface of the game board does not become flat, it takes time for the initial suction by the suction part, and the internal vacuum degree does not increase up to the specified vacuum set value and a sufficient suction effect cannot be obtained. .

  In particular, if a sufficient adsorption effect cannot be obtained, the game board may move in the cutting process, so that accurate cutting becomes difficult. In this case, since the processing accuracy is lowered, the quality of the formed game board is lowered.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a game board forming method capable of preventing a reduction in processing accuracy by enhancing an adsorption effect of a game board in a game board fixing process.

  In order to solve the above problems, the game board forming method according to the present invention is a game board forming method for forming a hole for attaching a predetermined game member to the board surface, and is elastically deformable. On the mounting table (vacuum table 110) on which the sealing member (sealing member 70) is provided on the mounting surface (mounting surface 110aa) and suction portions (vacuum holes 110a, 110b, 110c, 110d, 110e) are formed. A placing step of placing a game board (game board 30) at least partially composed of a synthetic resin in such a manner that a space is formed by a seal member between the game board and the placement table, and a seal member. The air in the space between the mounting table and the game board is sucked by the suction part, and the space between the mounting table and the game board is sealed by the sealing member, and the game board is placed on the mounting table (vacuum table 110, sub table). And executes the game board fixing step of adsorbing fixed table 115), and a processing step of performing processing with respect to the game board sucked and secured on the mounting table by the game board fixing process.

  Thus, in the placement process, the game board is placed on the placement table by the seal member so that a space is formed between the game board and the placement table, and the game board In the fixing process, the game board is sucked and fixed to the mounting table by sucking the air in the space formed by the seal member by the suction part.

  According to this, by sucking in the suction part, a sealed space can be formed between the game board and the mounting table, and from the outside (outside the space formed by the seal member) to the suction part. Air can be prevented from flowing in.

  Then, by continuing the suction by the suction part in this state, the internal vacuum degree of the sealed space can be increased to the specified vacuum set value, and a sufficient suction effect can be obtained in the game board fixing process. .

  As described above, according to the present invention, it is possible to enhance the adsorption effect of the game board in the game board fixing process, and thus it is possible to prevent a decrease in the machining accuracy in the machining process.

  Furthermore, according to the present invention, the air sucked by the suction portion is limited to the air in the space formed by the seal member, so that the time required for the initial suction can be shortened.

  In addition to the configuration of the invention described in claim 1, the present invention described in claim 2 cuts the game board with a cutting tool (router processing machine 120) disposed opposite to the game board in the machining step. It is characterized by doing.

  According to this configuration, the game board fixed to the mounting table in the game board fixing process is cut in the machining process.

  As described above, according to the present invention, when a gaming board fixing step having a high adsorption effect is executed, the gaming board is cut. Even if it occurs, it is possible to prevent a situation in which the suction of the game board is released and the game board moves. In this case, it is possible to accurately cut the game board and prevent a reduction in processing accuracy.

  In addition, if the processing accuracy can be prevented from being lowered, the quality of the formed game board can be prevented from being lowered, so that the placement of game members and the like on the game board can be performed more accurately, and normal games can be performed. It is possible to form a game board that can be played.

  According to a third aspect of the present invention, in addition to the configuration of the first or second aspect of the invention, the mounting surface of the mounting table is formed along the seal member and accommodates a part of the seal member. It has a seal housing groove (seal housing groove 80).

  According to this configuration, the mounting surface of the mounting table is formed with the seal receiving groove for storing a part of the seal member. Therefore, when the seal member is pressed by suction in the game board fixing process, the seal Of the member, a portion that cannot be accommodated in the seal accommodation groove in the normal state is accommodated in the accommodation groove.

  In this case, the volume of the portion of the seal member that protrudes from the receiving groove can be reduced, so that the game board and the mounting table can be brought into a plane contact state, and the adsorption effect of the game board in the game board fixing process can be improved. Can be increased.

  The present invention according to claim 4 is characterized in that, in addition to the configuration of the invention according to any one of claims 1 to 3, the seal member is arranged outside the suction portion.

  Thus, since the seal member is arranged outside the suction part, it becomes easier to form a sealed space between the game board and the mounting table by the suction of the suction part. It can prevent more reliably that the air from the outside flows into a part.

  In this case, it is easier to increase the internal vacuum degree of the sealed space to the prescribed vacuum set value, and the effect of adsorbing the game board in the game board fixing process can be further increased.

  The present invention according to claim 5 is characterized in that, in addition to the configuration of the invention according to any one of claims 1 to 3, the seal member is arranged at a position surrounding the suction portion.

  Thus, since the seal member is arranged at a position surrounding the suction part, it becomes easier to form a sealed space between the game board and the mounting table by the suction of the suction part. The air from the outside can be more reliably prevented from flowing into the suction part.

  In this case, it is easier to increase the internal vacuum degree of the sealed space to the prescribed vacuum set value, and the effect of adsorbing the game board in the game board fixing process can be further increased.

  In addition, according to the present invention, since the seal member only needs to be disposed at a position that can at least surround the suction portion, for example, the seal member can be disposed at a position near the outline of the suction portion. It is. In this case, the volume of the sealed space formed by the suction of the suction part can be reduced. As a result, the amount of air that needs to be sucked by the suction section can be reduced, and the time required for the initial suction can be further shortened.

  According to a sixth aspect of the present invention, in addition to the configuration of the invention according to any one of the first to third aspects, the mounting table includes a first mounting table (vacuum table 110) having a suction portion, and a through-hole. A hole is formed and divided into a second mounting table (sub-table 115) mounted on the top of the first mounting table. In the mounting process, the game board is placed between the through hole of the second mounting table. In the game board fixing step, the suction unit is configured to place the air in the space between the second table and the game board formed by the seal member in the second board. Suction is performed through the through hole of the mounting table.

  Thus, in the game board fixing step, the suction part sucks air in the space between the second mounting table formed by the seal member and the game board through the through hole of the second mounting table. . In this case, the part sucked by the suction part can be made different by changing the type of the second mounting table.

  For example, by placing the second mounting table with different positions of the through holes on the first mounting table, the portion to be sucked by the suction unit can be made different.

  Thus, by placing the second mounting table having a through hole formed in a portion facing the space to be sucked on the first mounting table, the air in the space can be sucked.

  According to this, it becomes possible to form various types of game boards with one first mounting table, and it is possible to increase the formation efficiency of the game boards.

  The present invention according to claim 7 is characterized in that, in addition to the configuration of the invention according to claim 6, the seal member is disposed outside the through hole.

  Thus, since the seal member is arranged outside the through hole, a sealed space is formed between the game board and the second mounting table by suction of the suction part through the through hole. It becomes easier, and it can prevent more reliably that the air from the outside flows into the said suction part.

  Then, by continuing the suction by the suction unit in this state, it becomes easier to increase the internal vacuum degree of the sealed space to the specified vacuum set value.

  The present invention described in claim 8 is characterized in that, in addition to the configuration of the invention described in claim 6, the seal member is disposed at a position surrounding the through hole.

  Thus, since the seal member is arranged at a position surrounding the through hole, a sealed space is formed between the game board and the second mounting table by suction of the suction part through the through hole. Can be more easily formed, and air from the outside can be more reliably prevented from flowing into the suction portion.

  Then, by continuing the suction by the suction unit in this state, it becomes easier to increase the internal vacuum degree of the sealed space to the specified vacuum set value.

  In addition, according to the present invention, the seal member only needs to be disposed at a position that can at least surround the through hole. For example, the seal member may be disposed at a position that is close to the outline of the through hole. Is possible. In this case, the volume of the sealed space formed by the suction of the suction part can be reduced. As a result, the amount of air that needs to be sucked by the suction section can be reduced, and the time required for the initial suction can be further shortened.

  According to the present invention, the following effects can be obtained.

  That is, according to the present invention, it is possible to increase the adsorption effect of the game board in the game board fixing process, and to prevent the processing accuracy from being lowered.

  Hereinafter, the best mode for carrying out the present invention will be described more specifically with reference to the drawings. Here, in the accompanying drawings, the same reference numerals are given to the same members, and duplicate descriptions are omitted. In addition, since description here is the best form by which this invention is implemented, this invention is not limited to the said form.

FIG. 1 is an explanatory view of the through chucker shown in FIG. Is a front view of a through chucker according to the first embodiment, FIG. 14 is an explanatory view of a through chucker from Y direction shown in FIG. 13.

  As shown in FIGS. 1 and 2, the mounting surface 110aa (that is, the upper portion of the vacuum table 110) of the vacuum table (first mounting table) 110 on which the mounting surface 110aa is formed flat has a plate-like shape. A sub table (second mounting table) 115 is placed, and a molded game board 30 is placed on the placing surface 115aa of the sub table 115. That is, the game board 30 is placed on the vacuum table 110 via the sub table 115.

  Further, as shown in FIGS. 1 and 2, the game board 30 is placed with the surface 30b facing upward. The vacuum table 110 according to the present embodiment has no side wall, but may have a box shape having a side wall.

  Here, the game board 30 is configured by a member such as a synthetic resin having translucency such as an acrylic resin, a polycarbonate resin, and a methacrylic resin, and has a plate shape. In addition, since the game board 30 is composed of a member such as a synthetic resin as described above, some of the game board 30 is already formed at the time of molding due to the characteristics of the synthetic resin (for example, plasticity, characteristics of being softened by heating, etc.). In many cases, it is warped (see FIGS. 1, 2 and 3A). The game board 30 may be transparent or translucent. Moreover, you may be comprised from members other than a synthetic resin.

  Inside the vacuum table 110 are a vacuum passage 110ab (FIGS. 3 and 4) that is a hole through which air flows, and a vacuum hole (a hole that penetrates from the vacuum passage 110ab to the mounting surface 110aa of the vacuum table 110). (Suction part) 110a, 110b, 110c, 110d, 110e are formed. Here, FIGS. 3 and 4 are cross-sectional views showing a state in which the game board 30 is placed on the vacuum table 110 and the sub-table 115 along the line AA in FIG.

  One end of the vacuum passage 110ab is electrically connected to the vacuum pump 200 via the pipe 210.

  The vacuum pump 200 includes a gas injection operation for injecting gas into the vacuum passage 110ab and the vacuum holes 110a, 110b, 110c, 110d, and 110e via the pipe 210, and the vacuum passage 110ab and the vacuum hole 110a, 110b, 110c, 110d, 110e is a device that performs a gas wicking operation and the like for sucking up the gas in 110e by generating pressure. In addition, the vacuum pump 200 shown in FIG. 1 to FIG. 4 as a cube or a rectangle conceptually shows the existence, and does not show an actual shape.

  Here, when the gas suction operation is performed by the vacuum pump 200, the air on the mounting surface 110aa of the vacuum table 110 is sucked from the vacuum holes 110a, 110b, 110c, 110d, and 110e. According to this, the member mounted on the mounting surface 110aa of the vacuum table 110 can be adsorbed and fixed to the vacuum table 110.

  Further, the vacuum table 110 according to the present embodiment forms five vacuum holes (vacuum holes 110a, 110b, 110c, 110d, and 110e) in order to suck the members placed on the placement surface 110aa more reliably. However, in the present invention, the number of vacuum holes in the vacuum table 110 is not particularly limited. Furthermore, the vacuum table 110 of the present embodiment is movable in the horizontal direction.

  The sub-table 115 placed on the vacuum table 110 is formed with a plurality of through holes 115a, 115b, 115c, 115d, and 115e, which are holes penetrating from the back side to the front side (FIGS. 1 to 4). reference).

  The through holes 115 a, 115 b, 115 c, 115 d, and 115 e face the vacuum holes 110 a, 110 b, 110 c, 110 d, and 110 e in the vacuum table 110 when the sub table 115 is placed on the vacuum table 110, respectively. (See FIGS. 1 to 4).

  According to this, when the gas suction operation is performed by the vacuum pump 200, the air on the mounting surface 115aa of the sub-table 115 is vacuumed through the through holes 115a, 115b, 115c, 115d, and 115e, respectively. Suctioned from 110a, 110b, 110c, 110d, and 110e. In this case, the game board 30 placed on the placement surface 115aa of the sub table 115 can be adsorbed and fixed to the sub table 115.

  Further, on the mounting surface 115aa of the sub-table 115, a seal member 70 capable of elastic deformation is provided outside the through holes 115a, 115b, 115c, 115d, and 115e, and the through holes 115a, 115b, 115c, 115d, and 115e. (See FIGS. 1, 2 and 5).

  The placement surface 115aa is formed with a seal accommodation groove 80 for accommodating a part of the seal member 70 along the seal member 70. The seal member 70 is partially accommodated in the seal accommodation. It is accommodated in the groove 80 (see FIGS. 1 to 6. Note that FIG. 6 is a sectional view taken along line BB in FIG. 5).

  That is, as shown in FIG. 6, the seal member 70 of the present embodiment is disposed on the placement surface 115aa of the sub table 115 in a state of protruding upward from the seal housing groove 80.

  The seal member 70 is made of an elastic member such as hard urethane, natural rubber, butadiene rubber, or silicone rubber, and is deformed according to pressure from the outside (see FIG. 6B). ).

  Here, the game board 30 is placed on the sub-table 115 by the seal member 70 so that a space 90 is formed between the game board 30 and the sub-table 115 (FIG. 3 ( a) and FIG. 6 (a)), and in the game board fixing step described later, the game board 30 draws air in the space 90 formed by the seal member 70 by the vacuum holes 110a, 110b, 110c, 110d, and 110e. It is sucked and fixed to the sub-table 115 by suction (see FIGS. 3B and 6B).

  According to this, the sealed space 91 can be formed between the game board 30 and the sub-table 115 by sucking through the vacuum holes 110a, 110b, 110c, 110d, and 110e. Specifically, the game board 30 is drawn in the direction of the sub-table 115 by being sucked through the vacuum holes 110a, 110b, 110c, 110d, and 110e, and accordingly, the seal member 70 is moved to the game board 30. While being compressed and deformed, the contact area between the seal member 70 and the back surface 30c of the game board 30 is increased and the gap between the seal member 70 and the game board 30c is filled, so that the sealed space 91 is formed. . Thereby, it is possible to prevent air from the outside (outside the space formed by the seal member 70) from flowing into the vacuum holes 110a, 110b, 110c, 110d, and 110e.

  Then, by continuing the suction through the vacuum holes 110a, 110b, 110c, 110d, and 110e in this state, the internal vacuum degree of the sealed space 91 can be increased to the prescribed vacuum set value, which is sufficient in the game board fixing process. It is possible to obtain a good adsorption effect.

  That is, according to this embodiment, even if it is the game board 30 (FIGS. 1-3 (a)) in which distortion, sink, warp, etc. occurred at the time of molding, the vacuum holes 110a, 110b, 110c , 110d, 110e, a sealed space 91 can be formed between the game board 30 and the sub-table 115. Therefore, the internal vacuum degree of the sealed space 91 is increased to a specified vacuum set value and sucked. An effect can be heightened (refer FIG.3 (b) and FIG.6 (b)).

  Here, the space to be sucked by the vacuum hole as the suction portion can be changed by changing the type of the sub-table placed on the vacuum table 110. For example, as shown in FIG. 7, if the sub-table 116 (FIG. 7) in which the through hole 115 e is not formed in the portion in the region F (FIGS. 2 to 5) is placed on the placement surface 110 aa of the vacuum table 110. The suction from the vacuum hole 110e is not performed on the space between the area F and the area G (FIGS. 2 and 7) facing the area F of the game board 30.

  In this way, by placing the sub-tables having different through-hole positions on the vacuum table 110, the portion to be sucked by the vacuum holes can be arbitrarily changed.

  In FIG. 4B, a router processing machine (cutting machine) that includes an arm part 122, a support member 123, and a cutter head part 124 above the game board 30, and that cuts the game board 30 with the cutter head part 124. Tool) 120 is arranged to face the game board 30.

  The arm portion 122 is provided so as to protrude from a main body portion (not shown), and is movable up and down and left and right. The support member 123 is provided at the projecting end of the arm portion 122, and the cutter head portion 124 is mounted on the lower end thereof. The cutter head portion 124 is provided facing downward from the lower end of the support member 123, and by rotating at high speed, a member that contacts the cutter head portion 124 can be cut.

  Therefore, the cutting (processing) of the game board 30 can be performed by the cutter head portion 124, and by this processing, an attachment hole (for example, an ordinary electric accessory 6 (FIG. 9)) is attached. The mounting hole 33 (FIG. 9)) and the like can be formed in the game board 30.

  Next, a method for processing the game board 30 by attracting it to the sub-table 115 based on the above configuration will be described.

  First, the sub table 115 is placed on the placement surface 110aa of the vacuum table 110 (see FIG. 1 and FIG. 2), and then the formed game board 30 is spaced between the sub table 115 by the seal member 70. 90 is formed and placed on the placement surface 115aa of the sub-table 115 (see FIG. 3 (a), hereinafter, the process is referred to as “placement process”). Next, by performing a gas suction operation by the vacuum pump 200, the air in the space 90 formed by the seal member 70 is sucked into the vacuum holes 110a, 110b, through the through holes 115a, 115b, 115c, 115d, and 115e. Suction is performed at 110c, 110d, and 110e. Then, by continuing this suction, the sealing member 70 seals the space between the sub table 115 and the game board 30, and the game board 30 is sucked and fixed to the sub table 115 (FIGS. 3B and 6B). Hereinafter, this process is referred to as “game board fixing process”).

  Further, in the present embodiment in which the space 90 is formed by the seal member 70, when air in the space 90 is sucked through the vacuum holes 110a, 110b, 110c, 110d, and 110e, FIG. 3B and FIG. As shown in (b), a sealed space 91 is formed between the game board 30 and the sub-table 115. Therefore, it is possible to prevent air from the outside (the outside of the space formed by the seal member 70) from flowing into the vacuum holes 110a, 110b, 110c, 110d, and 110e. Further, by continuing the suction through the vacuum holes 110a, 110b, 110c, 110d, and 110e in this state, it is possible to increase the internal vacuum degree of the sealed space 91 to the specified vacuum set value and enhance the adsorption effect.

  In this case, even if the game board 30 (FIGS. 1, 2, and 3A) in which distortion, sink, warp, or the like has occurred at the time of molding, the game board 30 and the sub table 115 are obtained by the suction. A sealed space 91 can be formed between them, and the internal vacuum degree of the sealed space 91 can be increased to a prescribed vacuum set value to enhance the adsorption effect.

  Further, when the seal member 70 is compressed by suction in the game board fixing process, a portion of the seal member 70 that cannot be accommodated in the seal accommodation groove 80 in the normal state is accommodated in the accommodation groove. (See FIG. 6 (b)).

  In this case, the volume of the portion of the seal member 70 that protrudes from the housing groove can be reduced, so that the game board 30 and the sub-table 115 can be brought into a plane contact state, and the game board 30 in the game board fixing process. The adsorption effect can be further enhanced.

  Further, in the game board fixing step, the pins 60 are inserted into the sub-table 115 through pin holes (not shown) formed in the corners of the game board 30. The position where the pin hole is formed is not limited to the corner portion of the game board 30 and may be formed at another position.

  Next, a processing step of cutting and processing the game board 30 that is attracted and fixed to the sub-table 115 is performed.

  Specifically, in the processing step, the router processing machine 120 is moved above the portion of the game board 30 to be cut and processed by a signal (not shown) (see FIG. 4B).

  Next, the cutter head portion 124 that rotates at a high speed is inserted into the portion to be cut and processed. Here, the insertion is performed until the tip of the cutter head part 124 reaches the back surface 30c of the game board 30 (that is, until the cutter head part 124 penetrates the game board 30).

  Then, by moving the vacuum table 110 or the arm part 122 on which the game board 30 is placed, the cutting by the cutter head part 124 is advanced to process the game board 30.

  In the present embodiment, by performing the above-described processing steps, the mounting hole 33 for mounting the ordinary electric accessory 6 and other types of mounting holes (for example, the mounting hole 31 for mounting the obstacle member 3, An attachment hole 32 for attaching the obstruction member 4, an attachment hole 36 for attaching the through chucker 400 (FIGS. 13 and 14), an attachment hole 34 for attaching the big prize device 7, etc. (see FIG. 9)) Can be formed.

  Further, in the processing step, a nail pilot hole 35 (FIG. 9) to which the nail 2 (FIG. 9) can be attached may be formed.

  The nail 2 is usually driven into the nail pilot hole 35 from an oblique direction. In order to form the corresponding nail pilot hole 35, it is necessary to form the nail pilot hole 35 by cutting obliquely. However, it is difficult to cut diagonally to form the nail pilot hole 35 from the back surface 30 c side of the game board 30. Therefore, in the present embodiment, it is desirable to perform the operation for forming the nail pilot hole 35 from the surface 30b side of the game board 30.

  Here, the conventionally used through chucker 300 will be described with reference to FIGS. 11 and 12. FIG. FIG. 11 is a front view of a conventional through chucker, and FIG. 12 is an explanatory view of the through chucker shown in FIG. 11 viewed from the X direction.

  As shown in FIG. 11 and FIG. 12, the through chucker 300 is provided on the back surface 309b side of the sill plate 309, provided on the back side member 308 to be inserted into the mounting hole, and on the surface 309a side of the sill plate 309. It is comprised from the protrusion part 300a which protrudes in the front side from an attachment hole. The protruding portion 300a is formed with a passage hole 301 that is a hole penetrating from the upper end to the lower end, and the back side member 308 has a passage detection sensor 305 that detects a game ball passing through the passage hole 301. It is attached. Here, the passage detection sensor 305 is locked to the locking member 304 protruding in the opposite direction to the protruding portion 300 a and is fixed to the back side member 308.

  The passage detection sensor 305 is electrically connected to a relay board (not shown) via a harness 306, and when the passage detection sensor 305 detects a game ball, a detection signal indicating that is sent. The data is transmitted to the relay board via the harness 306.

  Further, on both sides of the back side member 308, locking portions 302 and 303 that are locked to the periphery of the mounting hole on the back side 30c side of the game board are provided protruding from the back side 309b side of the sill plate 309. .

  The locking portions 302 and 303 have protrusions 302a and 303a protruding sideways, respectively, and the locking causes the protrusions 302a and 303a to be attached to the mounting holes on the back surface 30c side of the game board. This is done by hooking around.

  Here, in the conventional through chucker 300, the back side member 308 is inserted into the mounting hole, and the locking portions 302 and 303 are locked around the mounting hole on the back surface 30c side of the game board. It was designed to be attached to the mounting hole.

  However, when the through chucker 300 is attached to the attachment hole, the engagement portions 302 and 303 are engaged with the engagement portions 302 and 303 around the attachment hole on the back surface 30c side of the game board. It is necessary to form a counterbore (dent) to be formed.

  In this case, it is necessary to perform an operation such as turning the game board upside down and cutting the work board, resulting in a reduction in work efficiency.

  Therefore, in the present embodiment, the through chucker 400 shown in FIGS. 13 and 14 is used as the through chucker attached to the attachment hole 36 in order to omit the work of forming the counterbore (dent). Here, FIG. 13 is a front view of the through chucker according to Embodiment 1, and FIG. 14 is an explanatory view of the through chucker shown in FIG. 13 viewed from the Y direction.

  As shown in FIGS. 13 and 14, the through chucker 400 is provided on the back surface 409 b side of the sill plate 409, provided on the back surface side member 408 inserted into the mounting hole 36, and on the surface 409 a side of the sill plate 409, It is comprised from the protrusion part 400a which protrudes from the said attachment hole 36 to the front side. The projecting portion 400 a is formed with a passage hole 401 that is a hole penetrating from the upper end to the lower end, and the back side member 408 has a passage detection sensor 405 that detects a game ball passing through the passage hole 401. It is attached. Here, the passage detection sensor 405 is locked to the locking member 404 protruding in the opposite direction to the protruding portion 400a and is fixed to the back side member 408.

  The passage detection sensor 405 is electrically connected to a relay board (not shown) via a harness 406, and when the passage detection sensor 405 detects a game ball, a detection signal indicating that is sent. The data is transmitted to the relay board via the harness 406.

  Further, in the through chucker 400 according to the present embodiment, screw fixing portions 402 and 403 that are screwed to screw holes 42 and 43 (FIG. 9) formed on both sides of the mounting hole 36 are provided on the protruding portion 400a and the back surface. At a position sandwiching the side member 408, the side plate 409 is provided so as to protrude from the back surface 409b side.

  In the through chucker 400 in the present embodiment, the back side member 408 is inserted into the mounting hole 36, and the screws 402a and 403a are inserted into the screw holes 42 and 43 through the screw fixing portions 402 and 403, respectively, and screwed. Thus, it can be attached to the attachment hole 36.

  According to this embodiment, it is possible to attach the through chucker 400 to the attachment hole 36 without forming the counterbore for locking the locking portion on the back surface 30c side of the game board.

  According to this, since it is not necessary to form counterbore on the back surface 30c side of the game board, work such as turning the game board upside down and cutting can be omitted, and work efficiency can be improved.

  In the present embodiment, holes (for example, screw holes 42, 43, mounting holes 31, 32, 33, 34) formed in the game board 30 in order to omit work such as turning the game board over and cutting it. , 36, nail pilot holes 35, etc.) are all preferably formed from the surface 30b side of the game board 30.

  In the above placement process, the game board 30 is exchanged via a subtable 115 that can be easily exchanged (the subtable 115 has a simple structure in which the vacuum passage 110ab or the like is not formed, so that exchange is easy). Therefore, the vacuum table 110 can be protected by the sub-table 115 and it is difficult to prepare a substitute by the cutter head unit 124 in the machining process. The possibility that the table 110 is damaged can be avoided.

  Here, when the above-described processing steps and the like are performed and the mounting hole 33 and the nail pilot hole 35 are formed in the game board 30, the nail 2 and the obstacle member are next placed on the surface 30b side of the game board 30. 3 and 4, a process of attaching the ordinary electric accessory 6 and the big prize device 7 is performed (see FIG. 9, hereinafter, this process is referred to as “game member attaching process”).

  In the game member attaching step, the nail 2 is driven into each nail pilot hole 35 in the game board 30, and the obstacle members 3 and 4 are attached to the attachment holes 31 and 32, respectively. Also, the ordinary electric accessory 6 and the big prize device 7 are attached to the attachment holes 33 and 34, respectively.

  In addition, after the game member attaching process is completed, a process of attaching the game board 30 to a gaming machine (not shown) is performed (hereinafter, this process is referred to as “game machine assembly process”). At this time, on the back surface 30c side of the game board 30, an effect image (for example, an animation corresponding to a game state, other notification information, etc.) is provided via a spacer 40 (FIG. 9) made of a light-transmitting member. ) And the like, a liquid crystal display device 50 (FIG. 9) having a display area 50a is disposed. Since the game board 30 and the spacer 40 are formed of a light-transmitting member, the display area 50a of the liquid crystal display device 50 is visible through the game board 30 and the spacer 40.

  Although the embodiment of the present invention has been described above, this is merely a specific example of the present invention, and does not specifically limit the present invention.

  In the present embodiment, the vacuum pump 200 is used as a pump for performing a gas suction operation, a gas injection operation, or the like. However, the present invention is not limited to this, and other types of gas suction operation, gas injection operation, etc. A pump may be used. For example, other types of pumps include reciprocating pumps, rotary pumps, centrifugal pumps, axial flow pumps, jet pumps, and the like.

  Further, as shown in FIG. 5, the seal member 70 in the present embodiment is continuously arranged outside the through holes 115 a, 115 b, 115 c, 115 d, and 115 e on the placement surface 115 aa of the sub-table 115. However, the present invention is not limited to this, and the position of the seal member 70 is not particularly limited. For example, it may be arranged in a discontinuous state outside the through holes 115a, 115b, 115c, 115d, and 115e (see FIG. 10), or may be arranged at other positions.

  Further, the seal member 70 in the present embodiment is arranged in a state of protruding from the seal accommodation groove 80, but the present invention is not limited to this, and the seal member 70 is not arranged in the seal accommodation groove 80. May be. For example, it may be provided so as to protrude as it is from the placement surface 115aa.

  Further, the sealing member 70 in the present embodiment has an elliptical cross section (see FIG. 6A), but the present invention is not limited to this, and the sealing member 70 has a cross section. May have a shape of a quadrangle, or other shapes.

  Further, in the present embodiment, the through chucker 400 is configured to be screwed into the screw holes 42 and 43 via the screw fixing portions 402 and 403, but is not limited thereto. It may be configured to be pinned or may be configured to be adhered to the surface of the game board.

  As described above, according to the present embodiment, in the placement process, the game board 30 is configured so that the space 90 is formed between the game board 30 and the sub table 115 by the seal member 70. In the game board fixing process, the game board 30 sucks air in the space 90 formed by the seal member 70 through the vacuum holes 110a, 110b, 110c, 110d, and 110e. Thus, it is fixed to the sub-table 115 by suction.

  According to this, by sucking through the vacuum holes 110a, 110b, 110c, 110d, and 110e, which are suction portions, a sealed space 91 can be formed between the game board 30 and the sub-table 115, and the vacuum Air from the outside (outside the space formed by the seal member 70) can be prevented from flowing into the holes 110a, 110b, 110c, 110d, and 110e.

  Then, by continuing the suction through the vacuum holes 110a, 110b, 110c, 110d, and 110e in this state, the internal vacuum degree of the sealed space 91 can be increased to the prescribed vacuum set value, which is sufficient in the game board fixing process. It is possible to obtain a good adsorption effect.

  Thus, according to the present invention, it is possible to increase the adsorption effect of the game board 30 in the game board fixing process, and thus it is possible to prevent a decrease in the machining accuracy in the machining process.

  Furthermore, according to the present invention, the air sucked by the vacuum holes 110a, 110b, 110c, 110d, and 110e is limited to the air in the space formed by the seal member 70. Can be shortened.

  Further, according to the present embodiment, the game board 30 fixed to the sub-table 115 in the game board fixing process is cut in the machining process.

  As described above, according to the present invention, the gaming board 30 is cut when the gaming board fixing step having a high adsorption effect is executed. Even if vibration occurs, it is possible to prevent a situation in which the suction of the game board 30 is released and the game board 30 moves. In this case, it is possible to accurately cut the game board 30 and prevent a reduction in processing accuracy.

  Further, if the processing accuracy can be prevented from being lowered, the quality of the game board 30 to be formed can be prevented from being lowered. Therefore, the gaming members (nails 2, obstacle members 3 and 4, ordinary electric accessory 6, and a prize winning device) 7) and the like can be more accurately arranged on the game board 30, and a game board 30 capable of playing a normal game can be formed.

  Furthermore, according to the present embodiment, since the mounting surface 115aa of the sub-table 115 is formed with the seal accommodation groove 80 for accommodating a part of the seal member 70, the seal member is sucked by suction in the game board fixing process. When 70 is pressed, a portion of the seal member 70 that cannot be accommodated in the seal accommodation groove 80 in the normal state is accommodated in the accommodation groove.

  In this case, the volume of the portion of the seal member 70 that protrudes from the housing groove can be reduced, so that the game board 30 and the sub-table 115 can be brought into a plane contact state, and the game board 30 in the game board fixing process. The adsorption effect can be further enhanced.

  Further, according to the present embodiment, the vacuum holes 110 a, 110 b, 110 c, 110 d, and 110 e are formed between the sub table (second mounting table) 115 formed by the seal member 70 and the game board 30 in the game board fixing process. The air in the space is sucked through the through holes 115a, 115b, 115c, 115d, and 115e of the sub-table 115, respectively. In this case, the portions sucked by the vacuum holes 110a, 110b, 110c, 110d, and 110e can be made different by changing the type of the sub-table that is the second mounting table.

  For example, by placing sub-tables having different through-hole positions on the vacuum table 110, the portion to be sucked by the vacuum hole that is the suction portion can be made different.

  As a result, by placing the sub-table, in which a through hole is formed in a portion facing the space to be sucked, on the vacuum table 110, the air in the space can be sucked.

  According to this, it is possible to form various types of game boards 30 with one vacuum table 110, and the formation efficiency of the game board 30 can be increased.

  Furthermore, according to the present embodiment, since the seal member 70 is arranged outside the through holes 115a, 115b, 115c, 115d, and 115e, the through holes 115a, 115b, 115c, 115d, The suction of the vacuum holes 110a, 110b, 110c, 110d, and 110e through 115e makes it easier to form the sealed space 91 between the game board 30 and the sub-table 115, and the vacuum holes 110a, 110b, 110c, It can prevent more reliably that the air from the outside flows into 110d and 110e.

  In this state, by continuing the suction through the vacuum holes 110a, 110b, 110c, 110d, and 110e, it becomes easier to increase the internal vacuum degree of the sealed space 91 to the specified vacuum set value.

  (Embodiment 2)

  The game board forming method of the present embodiment has a function shown below with some changes made to the functions of the first embodiment.

  In the present embodiment, as shown in FIG. 15, the individual through holes 115 a, 115 b, 115 c, 115 d, and 115 e are individually surrounded by the seal member 70. That is, the seal member 70 in the present embodiment is disposed at a position that individually surrounds each through hole.

  Therefore, according to the present embodiment, as shown in FIG. 16, the volume of the sealed space 92 formed by suction of the vacuum hole can be reduced. As a result, the amount of air that needs to be sucked through the vacuum hole can be reduced, and the time required for the initial suction can be further shortened (note that FIG. 16 shows a line CC in FIG. It is a sectional view).

  In the present embodiment, the through holes 115a, 115b, 115c, and 115d are compared to the seal member 70 that is located outside the through holes 115a, 115b, 115c, and 115d (the seal member 70 that is located on the right side in FIG. 16). The protrusion height of the seal member 70 (the seal member 70 located on the left side in FIG. 16) located inside is lower.

  According to this, the seal member 70 can be reliably brought into contact with the game board 30 (see FIGS. 1 to 3A) whose warpage increases as it goes toward the end portion. It becomes easier to form the sealed space 92 between the sub table 115.

  As described above, according to this configuration, the seal member 70 is arranged at a position surrounding the through holes 115a, 115b, 115c, 115d, and 115e, so that the through holes 115a, 115b, 115c, The suction of the vacuum holes 110a, 110b, 110c, 110d, and 110e through 115d and 115e makes it easier to form the sealed space 92 between the game board 30 and the sub-table 115, and the vacuum holes 110a and 110b. , 110c, 110d, 110e can be more reliably prevented from flowing in air from the outside.

  In this state, by continuing the suction through the vacuum holes 110a, 110b, 110c, 110d, and 110e, it becomes easier to increase the internal vacuum degree of the sealed space 92 to the specified vacuum set value.

  Further, according to the present invention, the seal member 70 only needs to be disposed at a position that can individually surround at least the individual through holes 115a, 115b, 115c, 115d, and 115e. It is also possible to arrange 70 at the position just near the outline of each through hole. In this case, the volume of the sealed space 92 formed by suction of the vacuum holes 110a, 110b, 110c, 110d, and 110e can be further reduced. As a result, the amount of air that needs to be sucked through the vacuum holes 110a, 110b, 110c, 110d, and 110e can be reduced, and the time required for the initial suction can be further shortened.

  (Embodiment 3)

  The game board forming method according to the present embodiment has the following functions by changing a part of the functions of the first and second embodiments.

  In the present embodiment, as shown in FIG. 17, the seal member 70 and the seal accommodation groove 80 that accommodates a part of the seal member 70 are vacuum holes 110 a, 110 b, 110 c, in the mounting surface 110 aa of the vacuum table 110. 110d and 110e are provided outside, and the game board 30 is directly placed on the placement surface 110aa of the vacuum table 110. Even in this case, the adsorption effect of the game board 30 in the game board fixing process can be enhanced.

  According to this configuration, since the seal member 70 is arranged outside the vacuum holes 110a, 110b, 110c, 110d, and 110e, the game is performed by suction of the vacuum holes 110a, 110b, 110c, 110d, and 110e. It becomes easier to form a sealed space between the panel 30 and the vacuum table 110, and air from the outside can be more reliably prevented from flowing into the vacuum holes 110a, 110b, 110c, 110d, and 110e. .

  In this case, it is easier to increase the internal vacuum degree of the sealed space to the specified vacuum set value, and the adsorption effect of the game board 30 in the game board fixing process can be further increased.

  Further, the individual vacuum holes 110a, 110b, 110c, 110d, and 110e in the present embodiment are individually sealed in the same manner as the through holes 115a, 115b, 115c, 115d, and 115e (FIG. 15) in the second embodiment. The member 70 may be surrounded.

  In this case, since the seal member 70 is disposed at a position surrounding each of the vacuum holes 110a, 110b, 110c, 110d, and 110e, the game is performed by suction of the vacuum holes 110a, 110b, 110c, 110d, and 110e. It becomes easier to form a sealed space between the panel 30 and the vacuum table 110, and air from the outside can be more reliably prevented from flowing into the vacuum holes 110a, 110b, 110c, 110d, and 110e. .

  In this case, it is easier to increase the internal vacuum degree of the sealed space to the prescribed vacuum set value, and the effect of adsorbing the game board in the game board fixing process can be further increased.

  Further, according to the present invention in which the individual vacuum holes 110a, 110b, 110c, 110d, and 110e are respectively surrounded by the seal member 70, the seal member 70 surrounds at least the vacuum holes 110a, 110b, 110c, 110d, and 110e. For example, the seal member 70 can be disposed at a position near the outline of the vacuum holes 110a, 110b, 110c, 110d, and 110e. In this case, the volume of the sealed space formed by suction of the vacuum holes 110a, 110b, 110c, 110d, and 110e can be reduced. As a result, the amount of air that needs to be sucked through the vacuum holes 110a, 110b, 110c, 110d, and 110e can be reduced, and the time required for the initial suction can be further shortened.
