Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a board case for housing a circuit board on which a control ROM or the like for a gaming machine is mounted.
[0002]
[Prior art]
In a conventional gaming machine, a board case that houses a circuit board that controls the game is provided on the back side. In the case of a pachinko machine, the circuit board is mounted with various electronic components such as ICs and resistors that form a control circuit such as a main control device that controls the game and a payout control device that controls the ball payout device. It serves to protect the circuit board from the outside.
[0003]
In recent years, in the pachinko hall where such a pachinko machine is installed, an act of illegally exchanging the ROM of the main controller that determines the jackpot or the like according to a stored program has been performed. Thus, a technique for providing a sealing portion in the substrate case to prevent unauthorized opening is disclosed. Specifically, a structure in which a board on which various electronic components are mounted is bolted to a case body (a member attached to a pachinko machine) of a board case, covered with a cover part, and sealed with a sealing part. Adopted.
[0004]
The substrate case of the pachinko machine is once sealed after manufacturing using this sealing portion, but can be opened multiple times because it may be opened by an organization such as the police. For example, as the sealing portion, a plurality of bosses are provided on the edges of the case main body and the cover portion, respectively, and when the case main body is covered with the cover portion, the positions of both bosses are aligned. In this way, one or two of the bosses whose positions are aligned are fixed using a one-way screw or the like. In this way, the only way to open the package is to cut the boss from the substrate case. If two bosses are used for one-time sealing, the sealing can be performed a number of times that is 1/2 of the number of bosses provided in the case body.
[0005]
[Problems to be solved by the invention]
By the way, since the one-way screw cannot be loosened, the one-way screw used for sealing once cannot be removed from the boss. Accordingly, when sealing again, it is necessary to prepare a new one-way screw. However, since the one-way screw is a special screw, it takes time and effort.
[0006]
This invention is made | formed in view of this subject, and it aims at providing the board | substrate case which reduced the effort at the time of opening a sealing part and resealing.
[0007]
[Means for Solving the Problems]
The board case of the gaming machine according to claim 1 of the present invention made to solve such a problem is aligned when the case main body, the cover portion, and the case main body and the cover portion are superposed. A circuit board on which electronic components for controlling a gaming machine are mounted by inserting a tightening member into the opening prevention part. In the gaming machine board case,
An open end is connected to the cover portion outside the substrate case, and a U-shaped connecting member in which a space capable of accommodating a preliminary fastening member which is a reserve of the fastening member is formed is provided.
The pre-tightening member is formed integrally with the cover part via the connecting member in a state of being arranged in the internal space of the connecting member, and at a location facing the cover part in the connecting member. It is attached to the connecting member.
[0010]
According to a second aspect of the present invention, in the board case of the gaming machine according to the first aspect, the preliminary fastening member is integrally formed as many times as possible for resealing.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
In the board case of the gaming machine according to claim 1 (hereinafter also referred to as a board case), the circuit board is accommodated by superposing the cover portion and the case body. Holes are formed in the cover part and the case body, respectively, and when they are overlapped with each other, the holes are aligned and communicated. This is an opening prevention part. When the tightening member is inserted here, the superposition of the cover part and the case main body cannot be dissolved, and the circuit board can be sealed.
[0014]
In this substrate case, after the sealing is released, a preliminary fastening member used for resealing is held outside the substrate case. Therefore, according to the substrate case of the first aspect, it is not necessary to prepare a new tightening member when resealing .
[0020]
In the present invention described in claim 2 , the preliminary tightening member is integrally formed as many times as possible for resealing. In this way, it is not necessary to prepare any pre-tightening member required for resealing. Further, if the pre-tightening member is integrally formed at a visually recognizable position, the number of remaining pre-tightening members can be known how many times it can be resealed .
[0024]
【Example】
Embodiments of the present invention will be described below with reference to the drawings.
First, FIG. 1 is an explanatory view showing the back surface of a pachinko machine provided with a substrate case 1 to which the present invention is applied. As shown in the figure, the substrate case 1 is attached to the approximate center of the back surface of the pachinko machine, and is connected to the image control board 3, the prize ball control board 5, and the like via the connector group 7.
[0025]
FIG. 2 shows a perspective view of the substrate case 1. The substrate case 1 includes a case main body 9 that is directly attached to the pachinko machine, and a cover portion 11 that is superposed on the case main body 9. The cover portion 11 is formed of a transparent plastic resin having a lidless box shape, and a circuit board is accommodated therein. The circuit board is sealed by inserting the pin 13 into the pin insertion port 15 in a state of being superimposed on the case main body 9 shown in the figure. The case body 9 is also formed of a transparent synthetic resin.
[0026]
Four pin insertion openings 15 are prepared, which enables a total of four sealings including when the pachinko machine is shipped. The pin insertion port 15 is formed on the upper surface of the cover portion 11 with numbers indicating the order of use. That is, in this figure, the pin insertion openings 15 are used one by one in the order of the second from the left, the third from the left, the left end, and the right end. The pin insertion port 15 that is used first is formed at a position shifted forward from the other three pin insertion ports 15. This will be described later. Further, three spare pins 17 for performing the second and subsequent sealing are integrally formed on the cover portion 11 via the bracket 18. Although not shown in the figure, the order of the spare pins 17 to be used is indicated by numbers in the bracket 18 in order from the left of the figure as 2, 3, and 4 (1 is the pin 13). Here, the pin 13 corresponds to a fastening member, and the spare pin 17 corresponds to a preliminary fastening member.
[0027]
In the substrate case 1, the circuit board is attached to the cover portion 11. This is shown in FIGS. First, as shown in FIG. 3, bosses 23 a and 23 b indicated by broken lines are provided inside the cover portion 11, and screws 25 are screwed through the circuit board 21 to fix the circuit board 21. . At this time, the circuit board 21 is fixed so that the surface on which the electronic component group 27 is provided faces the cover portion 11. The connector cover 29 is attached to the cover portion 11 before the circuit board 21 is applied to the bosses 23a and 23b. The connector cover 29 is a frame-like member in which holes 32 corresponding to the shapes of the connectors of the connector group 7 are formed. When the circuit board 21 is fixed to the cover part 11, the connector group 7 is connected to the cover part via the holes 32. 11 is exposed. On the other hand, a connector window 33 is formed in the cover portion 11 to expose the connector group 7. This is shown in FIG.
[0028]
4 is a perspective view of the state in which the connector cover 29 is attached to the cover portion 11 as seen from the opposite direction to FIG. The connector window 33 is larger than the hole 32 of the connector cover 29, and some of the connectors forming the connector group 7 are collectively exposed from one connector window 33. This is because the cover 11 accommodates a case where a circuit board having a connector shape or number different from that of the circuit board 21 is accommodated. The connector cover 29 is detachably attached to the cover portion 11 by fitting holes 35 having substantially the same diameter as the bosses 23a formed near both ends thereof into the bosses 23a. Therefore, it is possible to deal with circuit boards other than the circuit board 21 by simply replacing the connector cover 29.
[0029]
FIG. 5A shows how the circuit board 21 is attached to the cover portion 11. FIG. 5A is a perspective view of this state seen from the same direction as FIG. After the connector cover 29 is attached to the cover part 11, the circuit board 21 is placed with the side on which the electronic component group 27 is mounted facing the bottom surface 37 of the cover part 11, and fixed with screws 25. Then, as shown in FIG.
[0030]
FIG. 6 shows how the cover part 11 is superposed on the case body 9 (hereinafter also simply referred to as superposition). FIG. 6A shows a state before polymerization, and FIG. 6B shows a state after polymerization, both of which are shown by the AA ′ cross section in FIG. In this figure, only the configuration particularly important for the polymerization is shown, and the bosses 23a and 23b and the circuit board 21 are omitted.
[0031]
Four convex pieces 47 are respectively formed on the peripheral wall 45 on the near side of the case main body 9 and the peripheral wall on the other side (not shown). On the other hand, on the inside of the peripheral wall 49 (see FIG. 5) corresponding to the peripheral wall 45, there are four locking pieces 51 to be locked to the convex piece 47 and the convex piece 47 at the stage before locking. Three guide portions 53 are provided for positioning the cover portion 11 in contact with each other during the polymerization operation. Note that the lower surface 39a of the peripheral wall 39 serves as a substitute for the guide portion corresponding to the leftmost convex piece 47 in the figure.
[0032]
In order to superimpose the cover part 11 on the case body 9, the cover part 11 is positioned as shown in FIG. 6A, that is, the guide part 53 or the lower surface 39 a is positioned on the four convex pieces 47. . At this time, the positions of the cover portion 11 and the case body 9 in the longitudinal direction (the direction perpendicular to the paper surface in the figure) are also aligned. From this position, the cover portion 11 is brought close to the case body 9 and the convex piece 47 is brought into contact with the guide portion 53 (or the lower surface 39a). From this state, the cover part 11 is slid leftward in the figure. Then, the locking piece 51 is locked to the lower side of the convex piece 47 so that the cover portion 11 is not separated from the case body 9.
[0033]
Note that the cover 11 can be separated from the case body 9 by performing the operations described above in reverse. In order to perform sealing, the aforementioned pin 13 or spare pin 17 is inserted into the pin insertion port 15. This will be described with reference to FIGS.
FIG. 7 is a perspective view showing a state where the cover portion 11 is not superposed on the case body 9. The periphery of each of the four pin insertion openings 15 is raised like a wall. On the other hand, a sealing base 61 in which a rectangular hole 59 is formed at a position aligned with the pin insertion opening 15 is attached to the case body 9 side. A hole formed by communicating the pin insertion port 15 and the hole 59 corresponds to the opening prevention portion of the present invention. The hole 59 of the sealing base 61 is a through hole, but the sealing base 61 is attached to the case main body 9 to have a bottom. Further, the sealing base 61 is black. Accordingly, even when the cover body 11 is superposed on the case body 9 which are both transparent, it is possible to clearly understand where the through hole of the pin insertion port 15 is, and the workability is good.
[0034]
The pin 13 has a substantially square shape. When the pin 13 is pushed into the pin insertion slot 15 (usually the second from the left), the bifurcated portion elastically deforms and enters the sealing base 61, and the cover portion 11. Is made difficult to slide with respect to the case body 9. This is shown in FIG. FIG. 8A is a cross-sectional view of the pin insertion port 15 into which the pin 13 is inserted, taken along the line BB ′ of FIG. As shown in the figure, a step is formed in the hole 59a, and the flange 63 of the pin 13 is locked here. At this time, the above-described wall-shaped portion 65 surrounds the top portion 67 of the pin 13. Since the bottom of the hole 59a is closed by the case body 9, it is very difficult to remove the pin 13 in this state. Furthermore, as shown in this figure, the direction in which the collar portion 63 of the pin 13 (same as the spare pin 17) bends is perpendicular to the sliding direction of the cover portion 11. For this reason, while the pin 13 (or the spare pin 17) is stuck in the pin insertion port 15, the cover portion 11 is forcibly slid to bend the flange portion 63 and the pin 13 (or the spare pin 17) is removed. It is impossible.
[0035]
When the seal is properly released, the wall-like portion 65 is cut off with a nipper or the like, and the pin 13 is cut and removed. At this time, the wall-shaped portion 65 can be easily cut because the first pin insertion opening 15 protrudes forward of the other through holes. The second and subsequent portions can be cut using a space formed by cutting away the wall-like portion 65 of the first through hole. As a result, space saving is realized at the location where the pin insertion opening 15 is formed.
[0036]
Further, when the seal is released, the date when the seal is released is written on the upper surface of the cover portion 11, and the sealing history is left. Thus, unless the pin 13 and the wall-like portion 65 are destroyed, it is difficult to unlock the substrate case 1. When the substrate case 1 is resealed, one spare pin 17 is cut out from the cover portion 11 and inserted into the third through hole from the left of the pin insertion port 15. If one spare pin 17 is used for one sealing, the sealing can be performed up to four times, and the number of times the sealing is released can be known from the number of remaining spare pins 17. .
[0037]
Note that a mark 68 is formed on the top portion 67 of the pin 13 as shown in FIG. This indicates how many times the pin 13 (or the spare pin 17) is used for sealing. The pin 13 has one mark 68 and the three spare pins 17 have the mark 68. 2, 3 and 4 are formed.
[0038]
The sealing base 61 is fixed to the case body 9 with screws 69 from the inside. Therefore, it is impossible to remove the sealing base 61 only after the sealing is released. Further, the holes 59a, 59b, 59c, 59d of the sealing base 61 correspond to the arrangement of the pin insertion port 15, and only the hole 59a into which the pin 13 is inserted is the other as shown in FIG. The holes 59b to 59d are shifted forward (downward in the figure).
[0039]
FIG. 9 shows a cross section taken along the line CC ′ of FIG. As shown in the figure, the circuit board 21 is positioned above the boundary between the cover portion 11 and the case body 9 when superposed. Moreover, since the electronic component group 27 not shown in the figure is mounted inside the cover portion 11, even if a tool or the like is inserted from the direction of the peripheral wall 45, a ROM or the like mounted on the circuit board 21 It is impossible to exchange Since the electronic component group 27 is mounted inside the cover portion 11 and the cover portion 11 is formed of a transparent member, the electronic component group is passed through the bottom surface 37 from the outside of the cover portion 11 without opening. 27 can be seen.
[0040]
As described above, according to the substrate case 1 described above, since the spare pin 17 is formed integrally with the cover portion 11, it is troublesome to prepare a new spare pin 17 (or pin 13) when resealing. Is not required. In addition, since the three spare pins 17 are formed corresponding to the number of times of resealing (three times in the substrate case 1), it is not necessary to prepare at all. In addition, it is possible to know how many times the remaining spare pins 17 can be resealed. Further, since the spare pin 17 is protected by the bracket 18, the spare pin 17 is not accidentally removed in the assembly process to the gaming machine. Further, since the spare pin 17 is formed of the same material as that of the cover portion 11, the wall-like portion 65 and the spare pin 17 can be cut with the same tool (such as nippers) when opening, Can be disposed of in the same way.
[0041]
As described above, the substrate case 1 has been described as an embodiment of the present invention, but the present invention is not limited to such an embodiment and can be implemented in various modes.
For example, in the substrate case 1, the pins 13 and the spare pins 17 have the same shape except for the mark 68, but may have different shapes. And the pin 13 enters only the through hole of the pin insertion port 15 used first, the second spare pin 17 enters only the through hole of the pin insertion port 15 used second, and so on. In addition, if only the dedicated pin insertion port 15 can be used, it is possible to prevent the operator from inserting the pin 13 or the like into the wrong pin insertion port 15.
[0042]
Further, although the spare pin 17 is formed on the bracket 18 of the cover part 11, it may be formed directly on the cover part 11. Moreover, you may form in places other than these. This is shown in FIG. First, FIG. 10A shows the spare pin 17 formed inside the case body 9. In this way, since the spare pin 17 cannot be obtained unless the substrate case 1 is opened, it is possible to prevent an illegal act such that only the spare pin 17 is removed from the bracket 18. Although it is conceivable to form in the cover portion 11 instead of in the case main body 9, the electronic component group 27 exists on the cover portion 11 side. There is a risk that the arrangement of the parts group 27 may need to be changed. In this respect, if it is formed in the case main body 9, it is not necessary to consider restrictions due to the electronic component group 27.
[0043]
FIG. 10B shows an example in which the spare pin 17 is formed on the sealing base 61. Even if it does in this way, there can exist an effect similar to Fig.10 (a). Further, in this case, since the color of the spare pin 17 is the same color as that of the sealing base 61, when sealing is performed using the spare pin 17, the number of times of sealing is determined. This can be known by looking at the pin insertion opening 15. The color of the sealing base 61 may be a color other than black. Whatever color is used, if the color is not transparent, the position of the pin insertion port 15 can be easily understood, and workability is improved.
[0044]
Moreover, you may make a cover part as shown in FIG. In the cover portion 11 ′ shown in this figure, a recess 73 is provided in a part of the outside. Three concave portions 75 are erected in the concave portion 73, and the spare pin 17 ′ is held by sandwiching the convex portions 75. The spare pin 17 ′ is formed of the same material as that of the cover portion 11 ′, and is covered with a cover 77 after sandwiching the convex portion 75. The cover 77 is fixed to the cover part 11 ′ by screwing into the screwing hole 81 from the inside of the cover part 11 ′ through the through hole 79. This prevents the spare pin 17 'from being stolen.
[0045]
Even in this case, it is not necessary to prepare a new spare pin 17 'when resealing. Since three spare pins 17 'are formed corresponding to the number of times that can be resealed, it is not necessary to prepare at all. You can know if you can. In addition, although the spare pin 17 'is formed separately from the cover portion 11', the wall-like portion 65 'and the spare pin 17' are attached when opening. It can be cut with the same tool (such as a nipper) and the cutting waste can be discarded in the same way.
[0046]
Moreover, although the board | substrate case 1 was illustrated as an object for pachinko machines, you may apply to game machines other than a pachinko machine.
