Abstract

PROBLEM TO BE SOLVED: To prevent noise from a heat dissipating hole and the adverse effects of dust, etc. SOLUTION: A board housing box 50 comprises a box body 51 to which a game control circuit board 100 is installed and a transparent synthetic resin cover body 70 which is installed to the box body 51 so as to cover the game control circuit board 100 and on a part of which conductive fiber 97 is integrally formed. Heat dissipating holes 76 for dissipating heat inside are formed on the upper side of the cover body 70 where the conductive fiber 97 is integrally formed with the conductive fiber 97 is intact. Therefore, as no noise such as electromagnetic waves or dust, etc., enter through the heat dissipating holes 76, on-board electronic parts are not adversely affected. In addition, as the conductive fiber 97 is in the form of meshes, ventilation between the inside and the outside can be properly maintained. As a result the heat dissipating holes 76 can function to a sufficient degree.

For this reason, the game control circuit board is housed in a metal board storage box in order to prevent the microcomputer from malfunctioning under the influence of electromagnetic waves or static electricity from the outside. However, by exchanging the ROM in which the program for controlling the game operation is stored, it is possible to realize different game contents in many cases. Therefore, the ROM exchange is not permitted. To make it easier to find out
One in which a substrate storage box is made of a transparent synthetic resin has been proposed. However, when the substrate storage box is made of a transparent synthetic resin, there is a disadvantage that the electromagnetic shielding effect is weak and electronic components and the like are adversely affected by noise.

[0003]

SUMMARY OF THE INVENTION In order to solve the above-mentioned drawbacks, even if a transparent synthetic resin is subjected to a process of providing an electromagnetic shielding effect, the substrate storage box generally does not
There is a radiating hole to radiate the heat generated inside,
For this reason, there is a possibility that noise such as electromagnetic waves may enter through the heat radiation hole. Further, when a relatively large heat radiation hole is formed in order to enhance the heat radiation effect, it is conceivable that dust or the like may enter the inside and contaminate the circuit board, or adversely affect the electronic components to be mounted. The present invention
In view of the above circumstances, an object of the present invention is to provide a board storage box of a gaming machine which can prevent adverse effects such as noise and dust from heat radiation holes.

FIG. 13 is a cross-sectional view when a transparent conductive layer 140 according to another embodiment is integrally formed with a synthetic resin as a conductive layer.

The board storage box 50 includes a box body 51 as a mounting base for housing and supporting the game control circuit board 100, and a cover body 70 for closing the upper surface of the box body 51. The substrate storage box 50 assembled as described above can be detachably attached to a mounting table 110 which is fixed to a mounting boss 31a protruding from the rear surface of the mechanism plate 31 with screws 31b (see FIG. 7). It has become.
Hereinafter, each of the assembled components will be described.

First, the box body 51 is formed of a conductive synthetic resin (which may be metal) containing carbon powder in a rectangular parallelepiped shape having an open upper surface, and dissipates heat generated internally in almost the entire region of the side wall. Many heat radiation holes 52 are formed.
Since the heat radiating hole 52 is a very small round hole, noise such as electromagnetic waves, dust and the like hardly enter. A relatively large rectangular opening 53 is formed on the bottom surface of the box body 51, and an L-shaped engaging edge of the mounting table 110, which will be described later, engages with a longitudinal opening edge of the opening 53. Are formed in a hanging manner. The box 51
As shown in FIG. 4 (A), the bottom surface of the box 51 is raised slightly above the lower end of the side wall. They will be located on the same plane.

Further, a locking hole 60 is formed at the center of the front part of the bottom surface of the box body 51, and support positioning protrusions 55 are provided on the left and right sides of one long side, and the left and right sides of the long side on the other side. A stop projection 56 is provided to protrude. When the board storage box 50 is mounted on the mounting table 110, the locking hole 60
The entirety of the substrate storage box 50 is supported and fixed to the rear surface of the mechanism plate 31 by engaging with the locking projection 114 formed at 0. In addition, the support positioning projection 55 sandwiches and supports both ends of one long side portion of the game control circuit board 100 with a pressing member 79 described later provided on the cover body 70,
The stop projection 56 is for fixing and supporting both ends of the other long side of the game control circuit board 100 with screws 74 described later. The support positioning projection 55 and the stop projection 56 will be described later in detail.

Engaging holes 57 are formed at two places on one side wall in the longitudinal direction and one place on both side walls in the short side direction of the box body 51. When the cover body 70 is covered with the box body 51, the engagement hole 57 engages with a locking hanging piece 78 formed on the back surface of the cover body 70. In the normal state, the engagement state with the locking hanging piece 78 can be released from the outside by operating from outside, but in this embodiment, the short side of the box body 51 is Sealing paper 81 is affixed to a flat surface formed by a sealing paper sticking projection 61 projecting outward at the center of the upper edge and a sealing paper sticking projection 80 described later of the cover body 70. Since a part of the sealing member 81 is welded by the laser technique, when the box body 51 and the cover body 70 are separated from each other even when the engagement state between the engaging hole 57 and the locking hanging piece 78 is released, the sealing paper 81 is formed. Seal marks 82 (see FIG. 12) are left.

Further, the other side wall in the longitudinal direction of the box body 51 is formed as a wiring drawing recess 58 having a low height.
A plurality of elliptical openings 59 are provided. Opening 59
4A, as shown in FIG. 4A, a transparent plate 62 described below.
However, it does not have a function as a heat radiating hole, but contributes to a reduction in raw materials forming the box body 51.

In order to close the opening 53 of the box 51, a transparent plate 62 is provided in contact with the bottom of the box 51 from the inside. For this reason, through holes 64 are formed at the four corners of the transparent plate 62, and a spacing cylinder member 63 having a hole having the same diameter as the through hole 64 is provided on the upper surface. As shown in (A), the support positioning projection 55 and the stop projection 56 are retained at a predetermined position by passing through the support positioning projection 55 and the stopper projection 56. The lower surface of the game control circuit board 100 is in contact with the upper surface of the spacing holding tubular member 63 and is transparent. The space between the board 62 and the game control circuit board 100 is maintained.

By closing the bottom surface of the box body 51 with the transparent plate 62, the back surface (solder surface) of the game control circuit board 100 can be seen through from the outside. In the case of unauthorized manipulation (for example, connecting jumper wiring or mounting electronic components), it can be immediately recognized. In this sense, it is sufficient that the size of the opening 53 closed by the transparent plate 62 is such that the entire area of the solder surface can be seen while tilting the substrate storage box 50. A pressing projection 64 is provided at the center of one side of the transparent plate 62 in the longitudinal direction.
The holding projection 64 supports the pressure from above when connecting the wiring to the connector 106 of the game control circuit board 100 so that the game control circuit board 100 is not deformed.

On the other hand, the cover body 70 for closing the upper surface of the box body 51 is formed integrally by embedding a conductive fiber 97 as a conductive layer in a transparent synthetic resin. The other side is a partition piece 71 bent downward. The position of the partition piece 71 is such that when the cover body 70 is mounted on the box body 51, the connector mounting area 102 of the game control circuit board 100 appears outside to form the connection opening 75 as shown in FIG. It is bent at the position. Thus, it is possible to connect an external wiring to the connector 106 facing the connection opening 75 in a state where the cover body 70 is assembled to the box body 51. A fixing piece 72 having a stop hole 73 is protrudingly provided near both ends of the partitioning piece 71, and when the cover body 70 is covered with the box body 51, the game control circuit board 100 is fixed while being clamped. Stop hole 73 of piece 72
Correspond to the stop projections 56. This fastening structure will be described later in detail.

As shown in FIG. 7, the conductive fibers 97 embedded in the cover 70 are embedded by in-mold molding in a portion near the inner surface of the cover 70. For this reason, when the cover 70 is manufactured by integrally molding the conductive fiber 97 and the transparent synthetic resin, a depression is formed at the opening of the mesh-like conductive fiber 97 and the cover 7
The inside surface of 0 becomes an uneven wavefront (see FIG. 9A). Such a wavefront irregularly reflects the light that has entered the inner surface of the cover body 70, so that the fine mesh-shaped conductive fibers 97 have a lower transmission visibility than a normal transparent state. This has an effect that the inside can be more easily seen through as compared with the case where the surface is formed in a smooth shape.

Here, the conductive fiber will be briefly described. The conductive fiber is roughly divided into metal (copper, brass,
Nickel, aluminum, etc.) filaments are woven in a network, and synthetic fibers are coated or impregnated with conductive particles (copper, carbon, etc.). From the viewpoint of the electromagnetic shielding effect and light transmittance, 50 to 250 mesh (particularly, 10 to 250 mesh)
0-200 mesh is good), and the aperture ratio is 10
It is desirably 90% (especially, 30 to 80% is good). Then, due to the structure of the mesh, transmission visibility is inevitably deteriorated, but in order to suppress this, the conductive fiber is darkened (for example, black) avoiding the metal color, or embedded in a transparent synthetic resin. When used, the transparent synthetic resin is made dark to improve the transmission visibility.

In the area of the surface of the cover body 70 except for a separation cover body part 80 described later, a large number of heat radiation holes 76 for discharging the heat generated inside to the outside are formed. A key operation hole 98 facing a probability setting key 108 to be described later is formed in the section. Of these, the radiation holes 7
6, the conductive fiber 97 formed integrally with the cover body 70 is present as it is, but the conductive fiber 97
Is mesh-shaped, so that not only air permeability is ensured, but also the conductive fibers 97 can prevent intrusion of dust and dirt smaller than the heat radiating hole 76 and also prevent noise such as electromagnetic waves from entering. can do. Further, at the long side edge and the short side direction edge of the cover body 70, two hooking portions 77 are provided at appropriate intervals to engage with the upper edge of the side wall of the box body 51. Cover body 7 between stop portions 77
0 has a locking hanging piece 78 hanging downward. The locking hanging piece 78 has a claw 78a at the tip.
Is formed, and this claw portion 78a is engaged with the engagement hole 5 of the box body 51.
7.

A pressing member 79 is hung on the back surface of both sides of the cover body 70, and a sealing paper sticking projection 80 protrudes from the center of the short side of the cover body 70. The sealing paper sticking projections 80 are engaged with the recesses of the sealing paper sticking projections 61 of the box body 51 so as to be flush with each other, and are sealed at the boundary between the sealing paper sticking projections 61 and 80. Paper 81 is attached. Thus, the sealing paper 81 is made of the sealing paper sticking protruding pieces 61 and 8.
After being attached to the sealing paper 81, the laser oscillator 130 almost covers the vicinity of the center of the sealing paper 81 as shown in FIG.
Irradiation of the sealing paper 81 at the irradiated portion
Is welded to the boundary between the sealing paper affixing protruding pieces 61 and 80. Therefore, when the sealing paper 81 is forcibly peeled off, as shown in FIG. Peeled off with a hole in the center. For this reason, it can be easily determined whether or not the sealing paper 81 has been illegally peeled off. In addition, the sealing mark 82 by the laser beam 131
Is formed at the boundary, and if this is further removed, a trace will inevitably remain, making it possible to find fraudulent acts extremely easily. In addition, it is also possible to draw a character or the like with the laser beam 131 as the sealing mark 82. The sealing paper 81 is not limited to paper, but may be made of synthetic resin or vinyl.

The structure of the cover 70 is substantially as described above, but when the cover 70 is covered by the box 51, the game control circuit board 100 is supported inside by the pressing member 79 and the fastening piece 72. Fixed. Before describing the detailed configuration for supporting and fixing, the structure of the game control circuit board 100 will be briefly described. The game control circuit board 100 is formed of a printed wiring board as is well known, and its upper surface is formed. The electronic component mounting surface including the ROM 105 is used as a mounting surface, most of the mounting surface is used as the electronic component mounting area 101, and a part of the rear surface is the connector 1.
06 is the connector mounting area 102 in which the connector is mounted. On the game control circuit board 100, locking holes 103 corresponding to the support positioning protrusions 55 are formed on the left and right sides of one long side, and stop holes 104 corresponding to the stop protrusions 56 are formed on the left and right sides of the other long side. Is formed. Further, the ground line conductive portions 107a and 107b (FIG. 8)
Is printed. Further, the game control circuit board 100 includes a probability setting key 10 for setting the appearance probability of the big hit symbol of the variable display device 14 on the game board 11.
8 is provided, and a probability display LED 109 for displaying a set value is also mounted.

Next, the operation of the holding member 79 of the cover body 70 and the fastening piece 72 will be described below. In the box body 51 with the transparent plate 62 attached, the game control circuit board 10
The locking hole 103 on one long side of the “0” is inserted into the tip protrusion of the support positioning protrusion 55, and the stop hole 104 on the other long side is placed on the stop protrusion 56. In this state, the game control circuit board 100 is temporarily placed on the box 51. Then, the cover body 70 is mounted from above the box body 51. At this time, as shown in FIG. 4A, the distal end of the pressing member 79 contacts the upper surface of the game control circuit board 100, and the support positioning protrusion 55 penetrating through the locking hole 103.
Is engaged with a hole formed at the center of the pressing member 79, so that one long side of the game control circuit board 100 is pinched and stopped by the support positioning protrusion 55 and the pressing member 79. Become.

On the other hand, the stopper hole 73 of the stopper piece 72 coincides with the stopper hole 104 on the other long side of the game control circuit board 100,
In addition, since the stop hole 104 coincides with the stop protrusion 56 of the box body 51, the other long side of the game control circuit board 100 is stopped by fastening the screw 74 from above the fastening piece 72. The game control circuit board 100 is completely fixed in the board storage box 50 by being fixed while being sandwiched between the projection 56 and the fixing piece 72.

When the screw 74 is used, the conductive fiber 97 buried near the inner surface of the cover 70 and the ground line conductive portion on the upper surface of the game control circuit board 100, as shown in FIG. The ground line conductive portion 107a on the upper surface and the ground line conductive portion 107b on the lower surface of the game control circuit board 100 are electrically connected via the through hole 107c. Since 107a and 107b are fixed to the stopper projections 56 of the box body 51 formed of a carbon-containing conductive resin with metal screws 74, the conductive fibers 97 and the ground line conductive portions 107a and 107 are provided.
b is grounded via the box body 51 (and a mounting table 110 described later), or is connected to the ground line conductive portions 107a and 107b.
6 is externally grounded via a power supply line connected to the power supply line 6. Then, as shown in FIG. 7, the position having this ground structure is the RO of the game control circuit board 100.
Since it is configured at a position distant from M105 (although not shown in detail in the figure, an integrated circuit such as a CPU or a RAM is formed and is also distant from the electronic components), noise to electronic components that are likely to malfunction is generated. The current flow can be suppressed.

The cover 70 has a separation cover 83 formed therein. The configuration of the separation cover body 83 will be described in detail below mainly with reference to FIGS. The separation cover body portion 83 has a rectangular shape and has a ROM 105 mounted on the game control circuit board 100.
The cover 70 and the separation cover 83 are integrally formed by connecting projections 84 which are provided at corresponding positions in the upper portion of the upper part and are bridged two by two at appropriate positions in the longitudinal direction (this embodiment). In the form, it is formed integrally with a synthetic resin). Then, by cutting the connecting protrusion 84 using a tool such as a nipper, the separation cover body 83 can be completely separated from the cover 70.

On each of the four sides of the separation cover portion 83, a locking piece 85 having a claw at the tip is provided so as to protrude upward. The locking piece 85 is attached to the cover 70 by cutting the connecting projection 84 and separating the separation cover 83 and inspecting the ROM 105 at the time of sample inspection or the like, and then turning over the separation cover 83 again. It is used when doing. Thus, the locking piece 85 in the present embodiment
Are formed as a pair of protruding pieces back to back, and the claw portions at the tips are directed outward from each other. Of course, only one of the locking pieces 85 on the outer side (the side along the edge of the separation cover body portion 83) may be used. However, as will be described later, only one locking piece 85 destroys the locking piece 85. This is not a preferable example because there is a possibility that the engagement state can be released without doing so. The base of the inner locking piece 85 has a claw forming opening 88 for integrally molding the locking piece 85 with synthetic resin.
Are formed.

When the connecting projection 84 is cut to separate the separation cover body 83, a rectangular separation opening edge 87 is formed in the cover body 70. An engagement opening 86 that engages with the locking piece 85 when the separation cover body portion 83 is mounted upside down is formed at the location, and the separation cover body portion 83 corresponding to the engagement opening 86 has: A notch 89 for forming an engaging opening for integrally molding the engaging opening 86 with a synthetic resin is formed.
Also, when the separation cover body portion 83 is turned upside down and mounted, the positioning recess 90 in the separation cover body portion 83 and the positioning protrusion 91 in the cover body 70 are each one so that the mounting direction can be easily understood. Formed on the side. Further, along the separation opening edge 87 of the cover body 70, an internal rib 92 for reinforcement is provided.
Are projected downward, and the engagement opening 86 is formed using the internal rib 92. In addition, the conductive fiber 97 is embedded in the inner surface of the separation cover body 83, but the conductive fiber 97 is not integrally formed over the entire area of the separation cover body 83.
At a position corresponding to the OM 105, a blank region 96 where the conductive fiber 97 is not integrally formed is formed. Note that the conductive fibers 97 of the separation cover body portion 83 are electrically connected to the conductive fibers 97 formed in the entire area of the cover body 70 via the conductive fibers 97 in the connection protrusion 84 in the initial state. In addition, as the blank area 96, not only the position corresponding to the ROM 105 but also other electronic components (for example, CPU and R
AM, etc.).

Further, the separating cover body portion 83 and the cover body 70
In the initial connection state in which the cover projections 84 are connected to each other, an inner sealing seal 93 is attached in advance on the inner surface of the cover body 70 so as to be bridged between the separation cover body section 83 and the cover body 70. I have. By sticking the inner seal 93 in this manner, even after the separation cover body portion 83 is separated and the covering state is restored by the locking pieces 85 and the engaging openings 86 again, the sticking state of the inner seal 93 is maintained. Cannot be restored, so that it can be understood that the covering state of the separation cover body 83 has been released at least once. Note that the portion of the separation opening edge 87 to which the inner seal 93 is attached is the meandering opening edge 8.
The reason for this is to prevent the inner sealing seal 93 from being cleverly cut by inserting a cutter knife or the like from the separation opening edge 87. Also, the connecting projection 8
7, the separation cover body part 83 is once separated from the cover body 70, and the sealing mark 94 of the inner sealing seal 93 is formed.
Remains in the separation cover body 83, so that the connecting projection 84
, And if the connecting projection 84 cut again is adhered with an adhesive or the like, it is possible to know from the sealing mark 94 whether the fraud has occurred.

In the substrate storage box 50 configured as described above, the box body 51 and the cover body 70 are
Since it is welded and sealed by 1, it is impossible to separate the box body 51 and the cover body 70 and release the covering state of the game control circuit board 100. Therefore, in order to release the covering state, the connecting projection 84 must be cut with a tool such as a nipper to separate the separation cover 83 from the cover 70 and expose the ROM 105. However, when the connecting protrusion 84 is cut in this manner, the cut causes the connecting protrusion 84 to disappear, so that the R of the game control circuit board 100 can be obtained only from that point.
It can be determined whether or not the OM 105 has been subjected to illegal processing.

In the amusement arcade, one out of the pachinko gaming machines 1 arranged on the pachinko island stand by the regulatory agency.
In some cases, the inspection (sample extraction inspection) of the ROM 105 may be performed by extracting two or about two units. When such a sample extraction test is performed, as shown in FIGS. 3A and 4B, the connecting protrusion 84 is cut with a nipper or the like to separate the separation cover body 83, and the ROM 105 is stored. Exposed
After pulling out the ROM 105 and examining it,
105 is mounted on the game control circuit board 100, and thereafter, as shown in FIGS. 3B and 4C, the separation cover body 83 is turned over and the locking piece 85 is engaged with the engagement opening 86. Then, the separation cover body part 83 is attached to the cover body 70.

The mounting structure will be described in more detail. As shown in FIG. 5A, when one locking piece 85a is engaged with the engaging portion of the engaging opening 86a, the cover 70 and The incorrect pin 120 is removed from the gap with the separation cover body 83.
By inserting the locking piece 85 and elastically deforming it,
By releasing the engagement state between the locking piece 85 and the engaging portion of the engaging opening 86, and in this state, as shown in FIG. There is a possibility that the covering state can be released without destroying. On the other hand, as in the present embodiment, when the locking piece 85 is composed of a pair of back-to-back protrusions,
As shown in FIG. 6A, even if there is a minute gap L1 between the cover body 70 and the separation cover body 83 on the left and right, as shown in FIG. Even if the pin 120 is inserted and the gap is widened to L2 to disengage the engaged state, the other gap L1 becomes a gap L3 as close as possible to zero and the illegal pin 120 cannot be inserted. The engagement state between the other engagement piece 85 and the engagement opening 86 cannot be released, and as a result, the left and right engagement pieces 8
5 cannot be released at the same time, it is almost impossible to release the covering state based on the locking pieces 85 and the engagement openings 86. Therefore, in order to release the covering state, at least the locking piece 85 must be destroyed, and when the locking piece 85 is broken, a trace remains, and based on the trace, the game control circuit board 1
It can be determined whether or not the illegal processing has been performed on the ROM 105 at 00. In the above-described embodiment, the separation cover body 83
After being separated, it is turned upside down and fixed. However, the present invention is not limited to this. A locking piece 85 is formed on the inner surface of the separation cover body 83, and after being separated, it is rotated 180 degrees without being turned upside down and fixed. Is also good. In this case, since the locking piece 85 does not protrude from the outer side from the beginning, there is an advantage that the locking piece 85 is not broken by an unavoidable force.

In the state where the separation cover body portion 83 is mounted upside down as described above, the game control circuit board 100 is again covered, and in order to guarantee this covering state, the inspecting authority that has performed the inspection is required. Inspection sealed paper 95 issued by
May be attached so as to bridge between the separation cover body portion 83 and the cover body 70.

The substrate storage box 50 assembled as described above is detachably mounted on a mounting table 110 fixed to the mechanism plate 41 as shown in FIG. Here, the configuration of the mounting base 110 will be briefly described. The mounting base 110 is integrally formed of a conductive synthetic resin (which may be metal) containing carbon powder or the like, and the engaging piece 54 is formed at the center thereof. A pair of engaging rails 111 to be engaged are formed in an inverted L-shape, and guide pieces 112 (the guide pieces 112 are not necessarily required) projecting from upper and lower edges thereof to guide the side wall of the substrate storage box 50. I have. On the other hand, a locking release lever 113 that is elastically deformed is formed at one end of the mounting base 110, and a locking projection 11 that engages with the locking hole 60 is formed at the base of the locking release lever 113.
4 are protruded. In addition, a ground wire 115 is fixed to the mounting base 110 with screws as necessary.

When the board storage box 50 is mounted on the mounting base 110, the engaging piece 54 is pushed from the side of the mounting base 110 so as to be engaged with the engaging rail 111, and is further strongly pressed to stop. The locking release lever 113 is elastically deformed downward along the inclined surface on the upper surface of the projection 114, and finally the locking projection 114 and the locking hole 60 are engaged to complete the mounting. On the other hand, to remove the substrate storage box 50, the locking release lever 113 is pressed downward to release the engagement between the locking hole 60 and the locking projection 114, and the substrate storage box 50 is pressed in a direction opposite to the pushing direction. Can be easily removed by pulling in the direction of.

As described above, the substrate storage box 5 according to the embodiment
Although the configuration of the game control circuit board 100 according to the present embodiment has been described above, the game control circuit board 100 as a circuit board is attached to the board storage box 50 according to the present embodiment.
A box 51 as a mounting base having a transparent plate 62 as a see-through portion through which the back side of the box 0 can be visually recognized, and the box 51 is attached to the game control circuit board 100 so as to cover the game control circuit board 100, and is attached to the inner surface thereof. A cover body 70 as a cover member made of a transparent synthetic resin in which conductive fibers 97 as a conductive layer are integrally formed, and the box body 51 is fixed to the mechanism plate 31 of the gaming machine. Since the mounting table 110 is formed of a conductive material while being mounted facing the table 110, one side of the game control circuit board 100 is visually recognized from a large number of continuous meshes of the conductive fibers 97 as a conductive layer. The other side of the game control circuit board 100 can be visually recognized from the transparent plate 62 of the box body 51 as an attachment base, and is formed of the conductive fiber 97 and a conductive material. The attachment base 110 provides a sufficient shielding effect, and can protect the internal game control circuit board 100 without damage by the cover body 70 and the box body 51 made of a transparent synthetic resin material even when an external force acts. .

The board storage box 50 according to the present embodiment has a box 51 as an attachment base to which the game control circuit board 100 is mounted, and covers the game control circuit board 100 with respect to the box 51. And a cover member 70 as a cover member made of a transparent synthetic resin integrally formed with a conductive fiber 97 at a part thereof, and the conductive fiber 97 of the cover member 70 is integrally formed. Since the heat radiating hole 76 for radiating the internal heat is formed on the upper surface where the conductive fiber 97 is left, the heat radiating hole 7 is formed.
No noise such as electromagnetic waves invades from 6,
Since dust and the like do not enter the inside of the board storage box 50 from the outside, the mounted electronic components are not adversely affected. On the other hand, since the conductive fibers 97 have a mesh shape,
As shown in FIG. 9A, the air permeability between the inside and the outside can be sufficiently maintained, so that the function as the heat radiation hole can be sufficiently performed.

The substrate storage box 50 described above
In FIG. 9A, as shown in FIG. 9A, a conductive fiber 97 as a conductive layer is formed by in-mold molding near the surface of a cover body 70 made of a synthetic resin. Thus, the cover body 70 may be integrally formed in the middle. In addition to the method of directly in-molding the conductive fiber 97 into the synthetic resin constituting the cover body 70, FIG.
As shown in (A) and (B), a conductive plate 97a made of a synthetic resin impregnated with conductive fibers 97 may be attached to the inner surface of the cover body 70, or may be affixed, insert-molded, or in-mold molded in the middle. . In this case, vinyl chloride is suitable as a synthetic resin material to be attached to the conductive plate 97a by heating. The cover 70 is also provided on the conductive plate 97a.
By forming a large number of holes so as to coincide with the heat radiating holes 76, the ventilation efficiency is not degraded, dust can be prevented from falling into the interior, and a sufficient electromagnetic shielding effect is maintained. You can also.

Further, in the above-described embodiment, the case where the conductive fiber 97 is integrated with the cover body 70 has been described, but it is sufficient that the conductive fiber 97 is integrated with at least a part of the cover body 70. . Desirably, all of the box body 51, the transparent plate 62, and the cover body 70 that constitute the substrate storage box 50 are made of a transparent synthetic resin to integrate the conductive fibers 97, but as in the present embodiment, The reason why the conductive fibers 97 are integrated only into the cover body 70 is to reduce the cost because the conductive fibers 97 are extremely expensive, and even if the cost is reduced, the inside can be visually recognized. In addition, in order to obtain a sufficient electromagnetic shielding effect, the above-described structure is employed.

Further, in the above embodiment, the conductive fiber 97 is exemplified as the conductive layer. However, as shown in FIG. 13, the inner surface of the cover 70 (FIG. 13A), the cover 70
The transparent conductive layer 140 may be integrally formed in the middle (FIG. 13B). This transparent conductive layer 140 is made of gold,
Platinum, silver, tin, aluminum, nickel, palladium,
Vapor deposition, sputtering, metal such as antimony, metal oxide such as indium oxide, tin oxide and mixtures thereof
It is formed on a surface of a resin material or the like as a layer having a thickness having conductivity and transparency by a method such as ion plating or CVD. The thickness of the transparent conductive layer is usually 5
１０００1000 nm, and its electrical conductivity is 100
An electric resistivity of 00Ω / □ or less, preferably 1000Ω / □ or less is suitable. To form the transparent conductive layer 140 in the middle of the cover 70 shown in FIG. 13B, the transparent conductive layer 14 is first placed on one of the two covers 70a and 70b.
After forming 0, it can be configured by attaching another cover body.

When the transparent conductive layer 140 is formed on the inner surface (or the middle) of the cover 70, FIG.
As shown in (C), the anti-reflection layer 141 may be formed on the outer surface. The anti-reflection layer 141 is made of various dielectric materials such as zirconium oxide, magnesium oxide, silicon oxide, magnesium fluoride, and aluminum oxide. Like the transparent conductive layer 140, vacuum deposition, sputtering, ion plating, and CVD are performed. It is formed on the surface of a synthetic resin material by a method or the like, and since it is an extremely thin curtain, the inside can be seen through and the reflection on the outer surface of the synthetic resin material is prevented, so that the internal visibility is improved. Is improved.

When the transparent conductive layer 140 shown in FIGS. 13A, 13B, and 13C is formed on the cover 70, if the heat radiation holes 76 are closed by the transparent conductive layer 140, ventilation is stopped. In this case, the portion corresponding to the heat radiation hole 76 does not have the transparent conductive layer 140 and the transparent conductive layer 14 does not exist.
Also, from the method of forming the transparent conductive layer 140,
It is difficult to coat with. Therefore, what is shown in FIG. 13 is not an embodiment of the present invention.

In the above-described embodiment (first embodiment), the substrate storage box 50 is fixed to the rear surface of the mechanism plate 31 via the mounting table 110 formed of a conductive synthetic resin. Alternatively, a structure may be employed in which the mounting plate 110 is attached to the rear surface of the mechanism plate without the intervention of the mounting base 110. An embodiment having such a structure (hereinafter, referred to as a second embodiment) is shown in FIG.
This will be described with reference to FIGS. FIG. 14 is a plan view of the board storage box 150 according to the second embodiment, FIG. 15 is a side view showing a state where the board storage box 150 is mounted on the mechanism plate 190, and FIG.

First, the mounting base 151 is formed of a substantially square metal plate (conductive material), and its two corners on one side and the other side are bent upward to form a game control circuit board. A mounting hole 152 for mounting 180 is formed. Outside the mounting hole 152 located on the other side, a bent piece in which a see-through opening 155 is further formed is protruded. Further, below the mounting hole 152, a screw through hole 153 for inserting a screw 154 from the back surface thereof is formed. Thus, the game control circuit board 18 is attached to the mounting board 151.
In order to fasten the mounting hole 151, the game control circuit board 180 is placed on the upper surface of the mounting base 151, and a screw 154 is inserted through the screw through hole 153 on the back surface of the mounting base 151 to fix the mounting hole 15a.
2, and a fastening hole 1 formed in the game control circuit board 180
88, and further through a mounting hole 173 of a transparent cover body 170 described later (only two screws 154 penetrate) to form a screw hole 1 formed in the cover frame 160.
64, the game control circuit board 180 is attached to the mounting base 151, the transparent cover 170, and the cover frame 16.
It is fixed in a state covered by 0.

When the game control circuit board 180 is mounted on the mounting base 151, the entire upper surface of the mounting base 151 is closed by the game control circuit board 180. Cannot be seen from the back surface of the mounting base 151. For this reason, in the present embodiment, the cover frame 160 is provided so that the solder surface of the game control circuit board 180 can be visually recognized from the outside.
A see-through opening 163 is formed in the lower part of the side surface of the.

As described above, the game control circuit board 180 placed so as to cover the entire upper surface of the mounting base 151 has a box-shaped cover frame 160 and a transparent cover housed inside the cover frame 160. The body 170 covers a portion excluding a connector mounting area 182 described later. First,
The cover frame 160 will be described in detail.
Numeral 60 is formed in a cylindrical shape in which almost the entire upper surface of a rectangular parallelepiped box made of metal is opened, and a transparent cover 170 is housed inside so as to close the upper surface opening 161. In the upper part of the long side of the cover frame 160, a large number of heat radiation holes 162, through which noise such as electromagnetic waves and dust rarely enter, are formed. One long side and both short sides are formed. A rectangular see-through opening 163 is formed in the lower part of the side surface. The three side surfaces on which the see-through openings 163 are formed are formed so as to have a large depth.
Is covered with the game control circuit board 180, it is flush with the back surface of the mounting base 151, and the remaining one side surface (the connector mounting region 182 side) is formed to have a shallow depth. , Slightly above the upper surface of the game control circuit board 180.

A screw hole 164 is formed inside the lower four corners of the cover frame 160, and a mounting piece 165 is integrally formed outwardly at the lower end of the short side surface. The mounting piece 165 is attached to the game control circuit board 18.
When the cover 0 is covered with the cover frame 160, it is flush with the back surface of the mounting base 151.

Next, the transparent cover body 170 will be described in detail. The transparent cover body 170 is provided to close the upper opening 161 of the cover frame 160, and the transparent cover body 170 has an upper surface as shown in FIG. Many heat radiation holes 17
1 is formed. Although the conductive fibers 175 formed integrally with the transparent cover 170 are present in the heat radiation holes 171 as they are, the conductive fibers 175 are formed in a mesh shape, so that air permeability is ensured. In addition, the conductive fibers 175 can prevent intrusion of dust, dust, and the like smaller than the heat radiation holes 171 and also can prevent noise such as electromagnetic waves from entering.

The transparent cover 170 is formed in a box frame shape so that its short side and one long side have side surfaces, and the transparent cover 170 is attached to the cover frame 160 at the corners. At the time of insertion, an escape recess 172 for allowing the screw hole 164 to escape is formed, and a mounting hole 17 is provided below the escape recess 182 on the connector mounting area 182 side.
3 are formed. A pair of rib protrusions 174 are provided on the inner side surface on the short side in the up-down direction so as to contact the upper surface of the game control circuit board 180 in a covered state. Furthermore, on the inner surface of the transparent cover body 170,
The same conductive fibers 175 as in the first embodiment are in-molded.

The structure of the game control circuit board 180 covered by the cover frame 160 and the transparent cover body 170 will be described. The game control circuit board 180 is constituted by a printed circuit board as is well known, and the upper surface thereof is the CPU 183. , A ROM 184, a RAM 185, and a power supply circuit unit 186. The mounting surface is used as an electronic component mounting area 181.
A part of the side is a connector mounting area 182 on which the connector 187 is mounted. The game control circuit board 180 has the mounting holes 152 at the four corners of the electronic component mounting area 182.
Are formed. Further, the ground line conductive portions 189a, 189
b (see FIG. 18) is pattern-printed.

The substrate storage box 15 according to the second embodiment
0 is generally as described above, but in order to close the game control circuit board 180, the game control circuit board 1
80 is mounted on the upper part of the mounting base 151 so that the fixing holes 188 and the mounting holes 152 coincide with each other. In this state, the cover frame 160 in which the transparent cover body 170 is housed is placed from above, and the screw holes 164 is matched with the fixing hole 188. In such a state, the screw through hole 15 on the back surface of the mounting base 151 is
The cover frame 16 including the mounting base 151 and the transparent cover body 170 is inserted and screwed into the screw 154 from above.
The game control circuit board 180 can be covered with 0.

In the covered state, the connector mounting area 182 of the game control circuit board 180 projects outward from the cover frame 160 as shown in FIGS. Mounting piece 16
5 is located at the lower end, the mounting pieces 1
65 can be easily mounted by merely engaging it with the engaging piece 192 of the mounting projection 191 (it may be locked by another structure). In addition, in the covered state, the upper surface of the game control circuit board 180 (the electronic component mounting area 181)
Can be visually recognized from the transparent cover 170 that closes the upper surface opening 161. On the other hand, the soldering surface on the back surface of the game control circuit board 180 cannot be seen from the back surface of the mounting base 151 because the mounting base 151 is a metal member. 163, the back surface of the electronic component mounting area 181 can be visually recognized, and the connector mounting area 18 can be seen from the transparent opening 155 formed on one long side of the mounting base 151.
2 can be visually confirmed.

Further, as shown in FIG. 18, the conductive fiber 175 buried near the inner surface of the transparent cover 170 and the game control circuit are screwed by screws 154 when the game control circuit board 180 is covered. The ground line conductive portion 189a on the upper surface of the board 180 is electrically connected to the ground line conductive portion 189a on the upper surface of the game control circuit board 180.
b is conducted through the through hole 189c.
Since the ground line conductive portions 189a and 189b are fixed to the mounting holes 152 of the metal mounting base 151 with metal screws 154, the noise current picked up by the conductive fibers 175 and the ground line conductive portions 189a and 189b. May be grounded from the mounting base 151 via the mechanism plate 190, or may be ground line conductive portions 189a, 189a.
89b is grounded to the outside via a power line connected to the connector 187. Then, as shown in FIG. 17, the CPU 183, ROM 184, RA
Since it is configured at a position distant from M185, it is possible to suppress the flow of noise current to an electronic component that is likely to malfunction.

Although the board storage box 150 according to the second embodiment has been described above, the board storage box 150 according to the second embodiment is different from the game control circuit board 18 according to the second embodiment.
0 is a plate-shaped mounting base 151 which is mounted with a predetermined height, and a transparent portion is mounted on the mounting base 151 so as to cover the upper and side surfaces of the game control circuit board 180 and is provided on the upper and lower sides thereof. A cover frame 160 having a transparent cover body 170 and a see-through opening 163,
The mounting base 151 is formed of a conductive material whose interior is not visible, and conductive fibers 175 as a conductive layer are integrally formed on a transparent cover 170 which is a see-through portion of at least the upper surface of the cover frame 160. Therefore, one side surface (mounting surface) of the game control circuit board 180 can be visually recognized from among a large number of continuous meshes of the conductive fibers 175 as a conductive layer.
The other side (solder surface) of the game control circuit board 180 can be visually recognized from the 0 transparent opening 163, and a sufficient shielding effect can be obtained by the mounting base 151 formed of the conductive fiber 175 and the conductive material. Even if it is played and an external force acts, the internal game control circuit board 180 can be protected by the mounting base 151 and the cover frame 160 without being damaged.

Further, the board storage box 150 according to the second embodiment is attached to the game control circuit board 180 so as to cover the game control circuit board 180 and the mounting base 151 to which the game control circuit board 180 is mounted. And a cover frame 160 having a transparent cover 170 made of a transparent synthetic resin in which conductive fibers 175 are integrally formed in a part thereof.
And the conductive fiber 175 of the transparent cover body 170 is formed integrally with the conductive fiber 1.
Since the heat radiating holes 171 for radiating the internal heat are formed in a state where 75 is left, noise such as electromagnetic waves does not enter from the heat radiating holes 171, and dust and the like enter the substrate storage box 150 from the outside. Therefore, there is no adverse effect on the mounted electronic components. On the other hand, since the conductive fibers 175 have a mesh shape, the air permeability between the inside and the outside can be sufficiently maintained, so that the function as the heat radiating hole can be sufficiently performed.

In the second embodiment, the transparent cover body 170 has a box-like shape which closes the upper opening 161 of the cover frame 160 and has a side surface. A structure in which only the upper surface opening 161 is closed may be used. Further, as the conductive layer provided integrally with the transparent cover body 170, the same transparent conductive layer 140 as in the first embodiment may be used.

In the first and second embodiments described above, the integration of the conductive fibers 97, 175 and the synthetic resin is performed by combining the conductive fibers 97, 175 in the synthetic resin forming the covers 70, 170. Was described in the embodiment, but as shown in FIGS. 19A and 19B,
A conductive fiber impregnated plate 202 (which may be a transparent synthetic resin with a transparent conductive layer film affixed) prepared by incorporating conductive fibers into a synthetic resin formed separately from the synthetic resin forming the substrate storage box 200 is prepared. The conductive fiber impregnated plate 202
May be locked to a locking piece 201 formed on a cover body portion having a heat radiating hole of the substrate storage box 200.

As another example, FIGS. 20A and 20B
As shown in (1), the conductive fiber net 212 (or a transparent conductive layer film) may be used as it is without impregnating the synthetic resin. In this case, the conductive fiber net 2
A holding rod 213 having a locking hole 214 is fixed to both ends of the base 12, and the locking hole 214 is engaged with a welding locking pin 211 protruding from an end corresponding to a cover body having a heat radiating hole of the substrate storage box 210. After that, the head of the welding locking pin 211 is welded to prevent the holding rod 213 from dropping off by the welding portion 215, so that the conductive fiber net 212 is substantially covered by the cover body of the board storage box 210. It is configured to cover the entire surface.

Also in the embodiment shown in FIGS. 19 and 20, the inside can be visually recognized from between a large number of continuous meshes of conductive fibers, a sufficient electromagnetic shielding effect can be obtained, and an external force can be exerted. Does not damage the internal game control circuit board due to the permeable synthetic resin material.

[0069]

As is apparent from the above description, according to the present invention, the board storage box has a mounting base on which the control circuit board is mounted, and a cover for covering the circuit board with respect to the mounting base. A cover member made of a transparent synthetic resin, which is attached and a conductive fiber is integrally formed on a part of the cover member. Since the heat radiation hole that radiates the internal heat is formed with the fiber left, no noise such as electromagnetic waves enters from the heat radiation hole,
Since no dust or the like enters the board storage box from outside, it does not adversely affect the electronic components to be mounted.On the other hand, since the conductive fibers are mesh-shaped, air permeability between the inside and the outside is reduced. Since it can be sufficiently maintained, the function as the heat radiating hole can be sufficiently performed.
