Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a board box of a gaming machine, and is applied to a control board box of a pachinko machine, a slot machine, etc., for example.
[0002]
[Prior art]
Generally, a gaming machine such as a pachinko machine is provided with a control board for controlling the gaming machine. The control board is usually housed and sealed in a board box in order to prevent the ROM from being illegally rewritten or replaced.
For example, as shown in FIG. 13, in the conventional substrate box 1, the control substrate 4 is accommodated between the holding case 2 and the lid 3. Sealing portions 2 </ b> A and 3 </ b> A are provided on the outer peripheral ends of the holding case 2 and the lid 3 at positions facing each other. These blocking portions 2A and 3A are brought into contact with each other, and the one-way screw 5 is tightened into a predetermined screw hole. Once the one-way screw 5 is tightened, since the screw does not return in the loosening direction, the blocking portions 2A and 3A are locked, and the control board 4 is sealed in the board box 1.
[0003]
As a substrate box having such a sealing structure, for example, one using a one-way screw having a structure that cannot rotate in a loosening direction (see Patent Document 1), or one using a screw that seals a base body and a lid so that they cannot be removed. (See Patent Document 2) and the like.
[0004]
However, according to the board box of such a conventional gaming machine, when locking the sealing portions 2A and 3A, it is troublesome to tighten the screws, and the working time tends to be long. Moreover, when the operator's tightening degree (the number of times of screwing) varies, the lock of the sealing part may be released.
On the other hand, in place of the one-way screw, there is also known one that locks the sealing portion with a rivet (see Patent Document 3), but a special tool such as a riveter is required to caulk the rivet, and the preparation for work is complicated become.
In addition, there is a case in which the sealing part is locked by an engaging pin or the like at the same time that the lid is closed to the holding case (see Patent Document 4). In this type of substrate box, the sealing part is always locked when the lid is closed. For this reason, the sealing part may be locked even when locking is not required, and handling such as storage and transportation of the substrate box becomes inconvenient.

[Problems to be solved by the invention]
The present invention has been made in view of such a current situation, and provides a board box for a gaming machine that can lock a sealing portion of a board box with an extremely simple operation and only when necessary. The purpose is that.
[0007]
[Means for Solving the Problems]
In order to solve the above-described problems, the board box of the gaming machine of the present invention (first invention) has the following configuration. That is,
In the substrate box that houses the substrate between the holding case and the lid, and seals the substrate by abutting and locking the sealing portion of the holding case and the lid,
The blocking part is
A pair of sealing pieces provided at ends of the holding case and the lid and facing each other;
A structure provided between the sealing pieces so as to be detachable, and fitted to the sealing pieces by a pressure applied when the lid is closed to the holding case, and a connecting member that connects the sealing pieces inseparably with each other. It was.
[0008]
According to this invention (1st invention), when locking a sealing part, first, one end of a connection member is fitted to either one among a holding case and the sealing piece of a cover body. Next, when the lid is closed to the holding case, the other sealing piece is fitted to the other end of the connecting member by the pressure of the lid. Thereby, the sealing pieces of the holding case and the lid are connected to each other through the connecting member so as not to be separated, and the sealing portion of the substrate box is locked.
[0009]
Thus, according to the board box of the gaming machine of the present invention (first invention), when closing the lid to the holding case, a special tool is required by interposing the connecting member between the sealing pieces. The sealing part can be locked with a simple operation.
Moreover, in this invention (1st invention), if a connection member is removed when closing a cover body to a holding | maintenance case, a sealing piece will not be connected but a sealing part will not be locked. That is, it is only necessary to lock the sealing portion using the connecting member only when locking is necessary, and handling of the substrate box such as storage, storage, and transportation becomes easy.
[0010]
The substrate box of the present invention (second invention) is characterized in that holding means for holding the connecting member in an unconnected state is provided on at least one of the blocking pieces.
When the sealing part of the substrate box is not locked, it is necessary to remove the connecting member so that the holding case and the sealing piece of the lid are not connected. In this case, if the storage location of the connecting member is away from the substrate box, it is troublesome to find the connecting member when using the connecting member.
According to this invention (2nd invention), since a connection member is hold | maintained in the non-connection state by at least one of the sealing pieces, a connection member can be used immediately when needed, and the sealing part can be locked rapidly.
[0011]
As the means for holding the connecting member, for example, a protrusion for hooking the connecting member on the sealing piece may be provided. By making the connecting member into a cylindrical shape, the cylindrical hole of the connecting member can be hooked and held on the protrusion. A male member of a blocking piece for connecting the connecting members can also be used as the protrusion. When locking the sealing part, the female hole of the connecting member is fitted to the male member of the sealing piece, and when the sealing part is not locked, the direction of the connecting member is changed to fit the cylindrical hole to the male member. Can be kept in an unconnected state.
As another means for holding the connecting member, a drop-off preventing plate for storing the connecting member may be provided in the sealing piece. Moreover, you may make it provide a groove | channel, a hook, etc. in a blocking piece, and fasten a connection member in a non-connection state. These holding means can be employed alone or in combination.
[0012]
The present invention (third invention) is characterized in that the connecting member is provided with a male member that fits into at least one connecting female hole of the blocking pieces and penetrates the blocking piece.
When inspecting the ROM or the like of the control board, it is necessary to unlock the sealing part and open the board box. In this case, a method of cutting the sealing piece at the base portion of the holding case and the lid and releasing the lock of the sealing portion is conceivable.
However, when the sealing piece is cut at the root portion in this way, the operation is likely to be complicated, and the substrate box is likely to be deformed or cracked.
[0013]
According to the present invention (third invention), when the sealing part is locked, the male member of the connecting member penetrates the sealing piece, and the locking part of the male member protrudes outside the sealing piece.
When opening the board box, the male member comes out of the connecting female hole of the sealing piece by cutting the locking part of the male member with a nipper or a cutter, etc., and the locking of the sealing part is easily and reliably released. Is possible.
[0014]
The present invention (fourth invention) is characterized in that the blocking piece is provided with a blind plate that covers the locking portion of the male member.
In the present invention (third invention), in order to check whether or not the blocking portion is locked, it is usually sufficient to look at the state of the male member of the connecting member from the outside of the blocking piece. That is, it is possible to know whether or not the lock of the blocking part is released by checking the state of whether or not the locking part of the male member is cut.
However, it is also assumed that the locked state cannot be determined instantaneously because the locking portion of the male member is small. In particular, in order to check whether the substrate box has been opened illegally, it is important to quickly know the locked state of the sealed portion.
[0015]
According to the present invention (fourth invention), it is necessary to always remove the blindfold when releasing the lock of the blocking portion. That is, unless the blindfold is removed, the locking portion of the male member cannot be cut. As a result, it is possible to check at a glance whether the blocking portion is locked by checking whether or not the blindfold is removed, and it is possible to easily know whether or not the board box has been opened due to fraud. .
In addition, according to the blindfold plate of the present invention (fourth invention), the locking portion of the male member is crafted to prevent the lock portion from being unlocked illegally.
[0016]
As a method for manufacturing a substrate box according to the present invention, for example, it is desirable to integrally mold the box body and the sealing portion with a plastic material. This is because, according to such a manufacturing method, the same plastic material can be used for the box body and the sealing portion, and the board box can be easily recycled after the game machine is disassembled. Moreover, since the cut piece of the sealing part does not include a metal material such as a screw or a rivet, it can be easily collected as plastic waste and can be easily recycled.
In addition, as another manufacturing method of the board | substrate box by this invention, the method of manufacturing a box main body and a sealing part separately, and uniting them later may be sufficient.
[0017]
For example, polycarbonate can be used as the plastic material for manufacturing the substrate box.
The color of the plastic material is not particularly limited, but it is desirable to use a transparent or translucent material. This is because it is easy to visually recognize the inside from the outside of the board box, and it is easy to find abnormalities such as ROM.
[0018]
A gaming machine according to the present invention is characterized by including the board box according to the present invention (first to fifth inventions).
According to the gaming machine of the present invention, the sealing portion of the board box can be easily locked by connecting the connecting member to the holding case and the sealing piece of the lid. This simplifies the work of setting the board box on the gaming machine in a factory or the like. Further, since the connecting member can be stored in a non-connected state with the sealing piece, it is convenient to handle the substrate box when the sealing portion is not locked. Furthermore, even if the ROM is inspected after the holes are installed, the operation for opening and closing the substrate box can be performed easily and quickly.
Note that the type of gaming machine is not particularly limited, and the present invention can be applied to various gaming machines such as a pachinko machine, a slot machine, an arrange ball machine, and a sparrow ball machine.
[0019]

[0020]
The control board consists of a main board that controls the entire gaming machine and a sub board (display control board, sound control board, lamp control board, payout control board, launch control board, etc.), and some of these boards are individually In the board box. This embodiment demonstrates the example which applied this invention to the board | substrate box 10 for main boards among these board | substrate boxes. Of course, the present invention can also be applied to the substrate box of the sub-board if necessary.
[0021]
As shown in FIG. 1, the substrate box 10 includes a holding case 12 and a lid 13. A hinge portion 15 is provided at the lower end portion of the substrate box 10, and the lid portion 13 is attached to the opening portion of the holding case 12 by the hinge portion 15 so as to be opened and closed. When the lid 13 is rotated in the arrow direction in FIG. 1 from the state of FIG. 1, the control board 14 appears in the holding case 12.
[0022]
A pair of blocking portions 10 </ b> A and 10 </ b> A are formed at both left and right ends of the substrate box 10 in FIG. 1. After the main board 14 is stored in the board box 10, the control board 14 is kept sealed in the board box 10 by locking these sealing parts 10 </ b> A and 10 </ b> A by a predetermined operation. As will be described later, the sealing portions 10A and 10A are provided with a plurality (four) of locking mechanisms so that the substrate box 10 can be repeatedly opened and closed.
[0023]
Next, the configuration of the blocking part 10A will be described.
FIG. 3 shows a state where the blocking portion 10A is disassembled. 3A is a cross-sectional view of the sealing piece 12A of the holding case 12, and FIG. 3B is a cross-sectional view of the sealing piece 13A of the lid 13. A connecting member 20 shown in FIG. 4 can be connected between the blocking pieces 12A and 13A.
[0024]
As shown in FIG. 3A, a blocking piece 12 </ b> A is formed on the side surface of the holding case 12. The blocking piece 12 </ b> A includes a vertical plate 15 and a horizontal plate 16. The vertical plate 15 extends substantially perpendicular to the side surface of the holding case 12, and the horizontal plate 16 extends substantially parallel to the side surface of the holding case 12 at the tip.
[0025]
A male member 17 extending substantially perpendicularly to the inside of the vertical plate 15 is formed on the blocking piece 12A. A locking portion 18 that can be fitted into the connecting female hole H3 (see FIG. 5) of the connecting member 20 is provided at the tip of the male member 17. The front end of the locking portion 18 is a wedge-shaped inclined surface 18a.
[0026]
On the other hand, as shown in FIG. 3B, a blocking piece 13 </ b> A is formed on the side surface of the lid body 13. The blocking piece 13A has a vertical plate 21 and a horizontal plate 22 that are smaller in size than the blocking piece 12A. When the lid body 13 is closed to the holding case 12, the sealing piece 13A is fitted inside the sealing piece 12A, and the tip 13a of the lid body 13 abuts against the horizontal plate 15 of the sealing piece 12A and stops (see FIG. 6).
[0027]
The sealing piece 13A is provided with a connecting female hole H1 penetrating the vertical plate 21. A male member 32 of the connecting member 20 to be described later can be fitted into the connecting female hole H1. As shown in FIG. 1, the connecting female hole H1 is covered with a rectangular blindfold plate 26. As a result, the connecting female hole H1 cannot be directly seen from the outside of the blocking piece 13A.
[0028]
The blindfold plate 26 is fixed to the wall surface of the vertical plate 21 by a support plate 26a. A gap S1 is formed between the blindfold plate 26 and the connecting female hole H1. The locking portion 33 of the male member 32 of the connecting member 20 protrudes into the gap S1 (see FIG. 6).
When the support plate 26a is cut with a cutter or the like, the blindfold plate 26 is separated from the blocking piece 13A, and the gap S is opened.
[0029]
A guide hole H2 is opened at the end of the vertical plate 21 of the blocking piece 13A. A stopper 35 of the connecting member 20 described later is fitted into the guide hole H2 (see FIG. 6).
[0030]
As shown in FIG. 4, the connecting member 20 includes a rectangular tube 31. A male member 32 is formed substantially at the center of the top surface of FIG. A slit-like connecting female hole H3 is formed on the bottom surface of the cylindrical body 31. The male member 32 and the connecting female hole H3 are disposed on the central axis of the connecting member 20.
[0031]
The male member 32 includes a right member 32a and a left member 32b having symmetrical shapes. A locking portion 33 that can be fitted into the connecting female hole H1 of the blocking piece 13A is formed at the tips of the right member 32a and the left member 32b. Since the right member 32a and the left member 32b are bent in a direction approaching each other, the male member 32 is easily fitted into the connecting female hole H1. Further, the inclined surface 33a formed in the locking portion 33 also facilitates the fitting operation of the male member 32 to the connecting female hole H1.
[0032]
Auxiliary slits S2 and S3 are formed on both sides of the connecting female hole H3. Between the connecting female hole H3 and the auxiliary slits S2 and S3, straight long plate portions 31a and 31b are formed. When the male member 17 of the blocking piece 12A is fitted into the connecting female hole H3, the long plate portions 31a and 31b are bent outward so as to expand the connecting female hole H3, thereby facilitating the fitting operation of the male member 17. .
[0033]
A stopper 35 is raised at the side end of the top surface of the cylindrical body 31 in FIG. When the male member 32 is fitted into the connecting female hole H1 of the blocking piece 13A, the stopper 35 is fitted into the guide hole H2 (see FIG. 3B) to position the connecting female hole H1.
On the other hand, a stopper 36 extends at the end of the cylinder 31 on the rear side in FIG. When the stopper 36 holds the connecting member 20 in the non-connected state at the sealing portion, the stopper 36 hits the wall surface of the blocking piece 12A or 13A and plays a role of holding back the connecting member 20 (see FIG. 10).
[0034]
Next, a method for locking the blocking portion 10A will be described.
As shown in FIG. 5, first, the blocking piece 12A and the connecting member 20 are connected. When the connecting female hole H3 of the connecting member 20 is pushed into the engaging part 18 of the male member 17, the engaging part 18 expands the connecting female hole H3 by the inclined surface 18a and is engaged with the connecting member 20.
When the lid 13 is closed to the holding case 12 in this state (see the arrow in FIG. 5), as shown in FIG. 6, the blocking piece 13A is fitted into the blocking piece 12A, and the male member 32 of the connecting member 20 is blocked. The piece 13A is elastically fitted into the connecting female hole H1. And the latching | locking part 33 of the male member 32 protrudes in space | gap S1, and is latched by the blocking piece 13A.
As a result, the blocking pieces 12A and 13A are connected to each other through the connecting member 20 in an inseparable manner, and the blocking portion 10A is locked.
[0035]
As described above, according to the first embodiment, the sealing portion 10A of the substrate box can be reliably locked by a simple work process. Thereby, the assembly | attachment of the board | substrate box 10 to the pachinko machine 100 becomes easy, and an operator's burden can be reduced. Further, once the connecting member 20 is connected to the sealing pieces 12A and 13A, the connecting member 20 is not detached by the return of the male members 17 and 32, and the reliability of the sealing can be sufficiently secured.
Note that the order of connecting the connecting members 20 to the blocking pieces 12A and 13A is not limited to the above description. The connecting member 20 may be connected to the blocking piece 13A first, and the connecting member 20 may be connected to the blocking piece 12A later. It is also possible to simultaneously connect both the sealing pieces 12A and 13A by sandwiching the connecting member 20 and applying pressure.
[0036]
When unlocking the blocking part 10A, the blindfold plate 26 is removed by cutting with a cutter or nipper. Then, as shown in FIG. 7, the male member 32 of the connecting member 20 appears outside the blocking piece 13A. Here, when the locking portion 33 of the male member 32 is cut, the connection between the blocking pieces 12A and 13A is released, and the locking of the blocking portion 10A is released.
As described above, according to the substrate box 10 of the first embodiment, the blocking portion 10A can be unlocked by a simple operation without cutting the blocking pieces 12A and 13A from their roots.
[0037]
The blindfold plate 26 is always held on the blocking piece 13A except when the locking of the blocking portion 10A is released. That is, the blindfold plate 26 is removed only when the sealing portion 10A is once locked and then released, and in other cases, the blindfold plate 26 is left attached to the sealing piece 13A. Thereby, it is possible to instantly grasp whether or not the lock of the blocking portion 10A is released only by looking at the blindfold plate 26.
[0038]
Here, as shown in FIG. 1, in the present embodiment, a plurality (four) of connecting members 20 are arranged in parallel on the sealing portions 10 </ b> A on the left and right sides of the substrate box 10. Accordingly, a corresponding number of male members 17, connecting female holes H1, and blindfold plates 26 are also formed. That is, the blocking pieces 12A and 13A are provided with first to fourth lock mechanisms in the vertical direction in FIG.
Then, the substrate box 10 is sealed by the first lock mechanism when the pachinko machine 100 is shipped from the factory. At this time, the second to fourth lock mechanisms are not locked. When the board box 10 is opened for ROM inspection after the gaming machine is installed in the hall, the first locking mechanism is released. When the substrate box 10 is closed again, the substrate box 10 is sealed by the second lock mechanism. Similarly, when the substrate box 10 is opened again, the substrate box 10 is sealed using the third and fourth lock mechanisms.
[0039]
In this embodiment, at the time of re-sealing after undergoing ROM inspection in the hole in this way, the connecting member 20 of each locking mechanism is attached to the sealing portion 10A of the same substrate box 10 so that the second to fourth locking mechanisms can be used immediately. Is stored.
[0040]
Next, a method for storing the connecting member 20 will be described with reference to FIGS. When storing the connecting member 20 in the sealing part 10A, the connecting member 20 is stored in a non-connected state between the sealing pieces 12A and 13A. FIG. 8 is a perspective view showing a storage state of the connecting member 20, and FIGS. 9 and 10 are sectional views showing a state before and after storing the connecting member 20 shown in FIG. 8 between the sealing pieces 12A and 13A. is there. 9 and 10, the connecting member 20 is held with the male member 32 facing upward in the direction perpendicular to the paper surface.
[0041]
As shown in FIG. 8 and FIG. 9, first, the male member 17 is put into the cylindrical hole of the connecting member 20, and the connecting member 20 is placed on the blocking piece 12A. At this time, the connecting shafts of the male member 32 and the connecting female hole H3 of the connecting member 20 are rotated by 90 ° from the locked state, and are kept substantially parallel to the blocking piece 12A.
Next, as shown in FIG. 10, when the blocking piece 13A is fitted to the blocking piece 12A, the blocking piece 13A is fitted to the outside of the connecting member 20, and the connecting member 20 is accommodated between the blocking pieces 12A and 13A.
[0042]
When the connecting member 20 is housed between the blocking pieces 12A and 13A in this way, the connecting member 20 is caught by the male member 17 through the cylindrical hole, so that it does not fall out between the blocking pieces 12A and 13A.
Further, since the connecting member 20 is not connected to any of the sealing pieces 12A and 13A, the sealing portion 10A is not locked, and the lid 13 can be freely opened from the holding case 12.
Further, as shown in FIG. 10, when the connecting member 20 is stored, the sealing pieces 12A and 13A and the connecting member 20 come into contact with each other, and a gap is hardly formed between them. For this reason, the connecting member 20 is held in the sealed portion 10 </ b> A with no backlash.
Further, when locking the blocking portion 10A, the blocking pieces 12A and 13A can be connected immediately by simply changing the direction of the connecting member 20.
In addition, about the method of hold | maintaining the connection member 20 in the male member 17, you may utilize the right member 32a and the left member 32b of the male member 32 other than using the cylindrical hole of the connection member 20. FIG. That is, it is possible to hold the connecting member 20 on the male member 17 by pressing and holding the male member 17 between the right member 32a and the left member 32b.
[0043]
Thus, according to 1st Embodiment, since the connection member 20 can be stored in the sealing part 10A of the board | substrate box 10, the effort which searches the connection member 20 at the time of a lock can be saved. Moreover, since the sealing pieces 12A and 13A and the connecting member 20 can be kept in the non-connected state except when the lock is necessary, handling such as storage and transportation of the substrate box 10 becomes convenient.
[0044]
The substrate box 10 of the first embodiment is also suitable for recycling after dismantling. That is, in the configuration of the sealing portion of the substrate box according to the conventional example, an off-the-shelf metal product is often used for screws and rivets. For this reason, it is difficult to separate metal screws and rivets when the plastic substrate box is collected for recycling. On the other hand, in the configuration of the substrate box 10, each part of the sealing part such as the sealing pieces 12 </ b> A and 13 </ b> A and the connecting member 20 can be manufactured relatively easily with a plastic material. Thereby, there is an effect that the plastic material of the substrate box 10 can be easily recycled.
[0045]
Next, another embodiment of the present invention will be described. Note that, in other embodiments described below, components that are substantially the same as those of the first embodiment are denoted by the same reference numerals, and description thereof is omitted.
[0046]
A second embodiment of the present invention is shown in FIG.
As shown in FIG. 11, the substrate box of the second embodiment has a single male member 41 provided on the connecting member 20. The locking portion 42 of the male member 41 is formed with inclined surfaces 42a and 42a that approach each other toward the tip.
When locking the blocking portion, when the male member 41 is pushed into the connecting female hole H1 of the blocking piece 13A, the locking portion 42 expands the connecting female hole H1 by the inclined surfaces 42a and 42a, and locks to the outside of the blocking piece 13A. Is done. Thereby, the connection member 20 and the blocking piece 13A are connected.
When releasing the lock of the blocking part, if the base of the locking part 42 is cut with a cutter, nipper or the like, the male member 41 is detached from the connecting female hole H1, so that the connection between the connecting member 20 and the blocking piece 13A is released. It is burned.
[0047]
According to the second embodiment, when the male member 41 is connected to the connecting female hole H1, the lock cannot be released until the locking portion 42 is excised. For this reason, it is possible to know the locked state of the blocking portion only by looking at whether or not the locking portion 24 is cut. Moreover, the blindfold plate of the blocking piece 13A can be omitted, and the blocking portion can have a simpler configuration.
[0048]
A third embodiment of the present invention is shown in FIG.
In the substrate box of the third embodiment, two sets of male members 32 and 51 are provided on the connecting member 20. A male member 51 having the same configuration as that of the first embodiment is provided on the opposite side of the connecting member 20 to the male member 32 (left end portion in FIG. 12). A stopper 52 is formed at the side end of the connecting member 20, and a guide hole H5 that fits the stopper 52 is provided in the blocking piece 12A.
The sealing piece 12A is provided with a connecting female hole H4 that can be fitted to the male member 51. On the outside of the connecting female hole H4, a blindfold plate 53 is fixed to the blocking piece 12A by a support plate 53a.
[0049]
According to the third embodiment, when locking the blocking portion, the connecting member 20 has a symmetrical structure, so there is no need to worry about the orientation of the male member 32 or 51. Moreover, when releasing the lock | rock of a sealing part, since either the male member 32 or 51 should just be selectively removed from the sealing pieces 12A and 13A, workability | operativity becomes favorable.
When the connecting member 20 is held in the sealed portion, when the male member 32 or 51 is oriented perpendicularly to the paper surface from the state of FIG. 12, the connecting member 20 is not connected between the sealed pieces 12A and 13A. Can be stored. At this time, the horizontal plates 16 and 22 of the blocking pieces 12A and 13A act as dropout prevention plates.
[0050]
Although the first to third embodiments of the present invention have been described, the embodiments of the present invention are not limited to these, and various modifications can be made. You may change the shape of a connection member as needed. Further, the position and number of the blocking portions are not limited to the configuration of the first embodiment. For example, blocking portions are provided at the four corners of the substrate box, or only one blocking portion is provided on the opposite side of the hinge portion. It may be provided. Further, the blindfold can be omitted as necessary.
