Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control board storage box in a game machine such as a pachinko machine or a slot machine and a sealing member for sealing the box.

[0002]

2. Description of the Related Art Conventionally, in order to prevent unauthorized modification of a control board, for example, replacement of an unauthorized ROM in a game machine of this type, various measures have been taken for a control board storage box for storing a control board. However, in general, the cover body is screwed and fixed to the case body, and then a sealing seal is affixed between them to prohibit opening of the cover body and prevent unauthorized modification of the control board. To prevent
In the event that the cover body is opened and tampering is performed, the fact that the seal has been cut has been cut so that the fact that tampering has been performed can be easily found.

[0003]

However, in the above-mentioned conventional method, since the cover can be opened only by removing the sealing seal, the control substrate can be relatively easily remodeled. In addition, there is a problem that if the seal is cleverly re-attached after the unauthorized modification, it becomes difficult to detect the fact of the unauthorized modification.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a control board storage box for a gaming machine and a sealing member for the box, which can reliably prevent unauthorized modification of the control board.

[0005]

Therefore, a control board storage box according to claim 1 is a control board storage box for storing a control board for controlling a gaming machine, and covers at least one surface of the control board. A sealing portion for preventing separation of the cover body and the control board, or separation of the cover body and the case body covering the other surface of the control board, and a spare sealing member used for the sealing section is controlled by the control section; It is configured to be stored inside the substrate storage box.

According to this control board storage box, since the spare sealing member is stored inside the control board storage box, the sealing member is lost or stolen as compared with a case where it is stored in another place. Therefore, it is possible to prevent the sealing member from being abused (illegal resealing) and to more reliably prevent the control substrate from being tampered with.

[0007] Further, in the conventional control board storage box, a plurality of sealing portions are provided for a plurality of times to be opened based on a valid reason, and a spare sealing member is temporarily fixed to each spare sealing portion. Control board storage box (for example,
21638), but by storing the spare sealing member inside the box as described above,
There is no need to provide a plurality of sealing portions.

Here, the sealing member basically includes all means having a sealing function of making the control board storage box once unsealed, and includes, for example, a sealing plug, a shear screw or a one-way screw. To tell. The sealing plug has the function of closing the head of the screw (which does not need to have the sealing function) so that the screw cannot be loosened. This prevents the screws from being loosened, thereby preventing unauthorized opening and
Tampering can be easily detected. This plug can be used in combination with a normal screw or in combination with the above-mentioned shear screw or one-way screw. When used in combination, all of the plugs and screws may be stored in the control board storage box, or only the plugs may be stored and the screws and the like may be temporarily fixed to the spare sealing portion.

Further, since the spare sealing member is housed in the control board housing box, the spare sealing member cannot be diverted to another game machine (a game machine that has been actually tampered with). As a result, it is possible to avoid a situation in which it is impossible to determine which gaming machine control board has been tampered with, and thus to reliably prevent tampering.

According to a second aspect of the present invention, there is provided a control board storage box.
The control board storage box according to claim 1, wherein the sealing member is disposed inside the control board storage box.
The OM cover is configured to be stored using the space portion.

According to this control board storage box, the control board storage box of the gaming machine is usually provided with a ROM cover, and a spare sealing member is stored by using the space inside the ROM cover. There is no need to provide extra space for storage.

According to a third aspect of the present invention, there is provided a sealing member for preventing a control board storage box for storing a control board for controlling a gaming machine from being opened, and having a symbol corresponding to the control board storage box. It is characterized by having done.

According to this sealing member, it is possible to easily determine which sealing member is to be stored in which control board storage box by using the symbol attached to each sealing member, thereby making it possible to obtain illegal information. It is possible to prevent the sealing member of the control board storage box that has not been opened from being used for resealing the illegally modified control board storage box. The symbol attached to each sealing member may be, for example, a serial number (serial number) for all of the target gaming machines. By attaching the same symbol on the control board storage box side corresponding to the symbol attached to each sealing member, forgery of the sealing member itself can be prevented.

In order to prevent forgery of the sealing member, it is effective to attach a symbol to a special seal such as a hologram seal. In this case, since the seal may be peeled off, it is effective to take measures such as applying a transparent paint to the surface to which the seal is attached in order to prevent this.

The control board 311 is housed in the inside of the housing 2 with almost no gap. The control board 311 has a mounting surface 311a on the front surface and a solder surface 311b on the back surface. Mounting surface 311
On a, various electrical components such as a RAM, an IC, and a fuse (not shown) are mounted in addition to the ROM 318 and the various connectors 319 to 319. Although not shown, a shield plate made of a conductive material such as punching metal is interposed between the case body 312 and the control board 311. This shield plate allows static electricity due to rolling friction of the pachinko ball or the like to be generated. The control circuit 311 is shut off to prevent generation of noise due to the influence on the electronic components of the control board 311 due to the static electricity.

The control board 311 has four corners at the case 3
12 on each of the bosses 314 to 314, and in this state, the fixing screw 3 is screwed into the screw hole 314a of each of the bosses 314 to 314.
21 is attached to the inside of the case body 312. The cover body 313 is formed in a rectangular shape slightly smaller than the case body 312 so as to expose the left edge and the lower edge of the control board 311, and has a side wall 313 a on the outer periphery thereof as shown in FIG. ing.

Control board 31 not covered by cover body 313
The various connectors 319 to 3
19 are arranged. A rectangular box-shaped ROM cover 323 is arranged around the ROM 318 arranged on the mounting surface 311a of the control board 311. ROM
The upper end of the cover 323 is in contact with the inner surface of the cover body 313.

FIG. 4 shows the ROM cover 323 alone. This ROM cover 323 is used to
The upper and lower parts are separated by 3a. This partition edge 3
As shown, a total of six plug storage units 380 to 380 are provided on the upper surface side of 23a. The plug storage sections 380 to 380 are used to store a spare sealing plug 390 as described later, and have the same configuration at all six locations. Each of the plug storage portions 380 has two holding edges 380a, 38 having an arc-shaped cross section which are arranged to face each other along the periphery of the hole 323b formed in the partitioning edge 323a.
0a. A fixed gap is provided between the ends of the holding edges 380a and 380. Further, all the holding edges 380a to 380a are attached to the ROM cover 32.
The third frame edge 323c is formed at a height flush with the upper end of the frame edge 323c, and thus abuts against the inner surface of the cover body 313.
In addition, slits 323d to 323d are formed by cutting the lower end of the ROM cover 323 at appropriate positions. Each of the slits 323d to 323d is unevenly engaged with a convex portion around the ROM 318.
The cover 323 is positioned with respect to the ROM 318.

Next, as shown in FIG. 1, small-diameter heat-dissipating holes 326 to 326 for letting out heat generated inside the control board storage box 310 penetrate almost all over the cover body 313 in the plate thickness direction. Many are open. Also, on the surface of the cover body 313, a sticking part 327 of a model name sticker is provided.
And a sticking portion 329 of a seal for recording an opening history are provided, and a mounting hole 328 for a probability changing key switch is provided.

The cover body 313 has heat radiation holes 326 to 32
A total of three positioning holes 333 to 333 having upper, lower, left and right diameters larger than six are formed. Positioning hole 333 ~
333 is formed in a bottomed shape that does not penetrate. This is for the purpose of minimizing intrusion of foreign matter into the control board storage box 310, and prevents unauthorized modification by wire or the like from the positioning hole 333.

On the other hand, positioning projections 334 to 334 project from the lower surface of the case body 312 at positions (on the same axis) corresponding to the positioning holes 333. Therefore, for example, when a plurality of control board storage boxes 310 to 310 are stacked, the upper control board storage box 310 is inserted into the positioning holes 333 of the lower control board storage box 310.
By the engagement of the positioning projections 334, the collapse of the load on the control board storage box 310 can be prevented.
This is effective when the control board storage box 310 is transported, when the pachinko machine is stored in an assembly factory, or the like. Also,
When the control of the pachinko machine becomes complicated and the area of the control board 311 must be increased, one control board 3
If the control board 311 is used, it is difficult to accommodate it in the limited space behind the pachinko machine.
It is conceivable to use a plurality of control board storage boxes at that time, without preparing a special control board storage box, when stacking the same control board storage boxes 310 to 310 and mounting them on a pachinko machine, The positioning function by the engagement between the positioning holes 333 and the positioning projections 334 can advantageously prevent mutual displacement.

The positioning projection 334 prevents the collapse of the control board storage box 310 when the control board storage box 310 is stacked, and also allows the control board storage box 310 to be attached to the back surface of the pachinko machine (specifically, a protective cover or the like) by attaching the set plate 316 to the back. It also has a function of securely holding the control board storage box 310 when the control board storage box 310 is attached via the connector. That is, since the set plate usually has flexibility, the positioning projection 3
When the control board storage box 310 is not provided, the set plate may be bent by an external force from the lateral direction (the left-right direction in FIG. 1) of the control board storage box 310, and the control board storage box 310 may come off from the protective cover or the like. For this reason, a hole for engaging with the positioning protrusion 334 is provided in the protective cover or the like,
By engaging the positioning projections 334 with the holes of the protection cover when the control board storage box 310 is attached to the protection cover or the like, the control board storage box 310 can be prevented from falling off due to a lateral external force.

Next, as shown in FIG. 1, a case 312 and a cover 3
13 for inseparably sealing 13
6 are provided. In the present embodiment, the sealing unit group 3
36 are set at two locations on the left and right sides of the control board storage box 310. Each of the sealing part groups 336 and 336 includes a plurality (four in the drawing) of sealing parts 337 sealed by a sealing screw 338 and a sealing plug 390, respectively. A total of eight sealing portions 337 to 337 have the same configuration.

As shown in FIG. 2, the side wall 3 of the case body 312
A sealing boss 342 having a bottomed screw hole 342a is provided on 12a so as to protrude laterally through an opening 342b. On the other hand, a sealing fastening portion 344 corresponding to the sealing boss portion 342 is provided on the side wall 313a of the cover body 313.

Both opening portions 342b and 344b are formed thin in a neck shape, and can be cut by a cutting tool such as a nipper or a cutter. Further, on the mating surface of the sealing boss portion 342 and the sealing fastening portion 344, a circular engaging convex portion 346a and an engaging concave portion 346b that are fitted to each other are provided. The diameter of the engaging projection 346a on the sealing fastening part 344 side is set smaller than the diameter of the engaging concave part 346b on the sealing boss part 342 side. An appropriate gap is formed between the recess 346b.

FIG. 3 shows the seal fastening portion 344 alone. The seal fastening portion 344 is formed in a substantially cylindrical shape, and has a screw insertion hole 345 on the lower side in the figure and a plug holding hole 347 on the upper side in the figure. In the plug holding hole 347, slits 347a, 347a are cut into both sides in the radial direction to form a keyhole shape, and the slits 345a, 345a in the screw insertion hole 345 are also cut into both sides in the radial direction to form a keyhole shape. Is formed. The slit 345a on the screw insertion hole 345 side has a larger cutting dimension (longer in the radial direction) than the slit 347a on the plug holding hole 347 side, and therefore both slits 347a and 345a.
A step 348 is formed between them.

Although the screw insertion hole 345 is formed to have a slightly smaller diameter than the sealing screw 338 to be inserted, the screw insertion hole 345 can be expanded against the elasticity of the slits 345a, 345a formed on both sides. Therefore, the sealing screw 338
Is inserted while pushing and expanding the screw insertion hole 345.
Thus, as shown in FIG. 6, the sealing screw 338 can be temporarily fixed to a state in which only the tip is inserted into the screw insertion hole 345 without being screwed into the screw hole 342a. .

A sealing plug 390 is provided in the plug holding hole 347.
Is inserted. FIG. 5 shows the sealing plug 390 alone. This sealing plug 390 has a circular head 390 having a diameter that can be inserted into the plug holding hole 347 with almost no gap.

When fitted in the hole 347, the sealing of the sealing portion 337 of the sealing number “2” is completed, and the control board storage box 310 can be resealed. By repeating this, sealing can be performed again in the order of the sealing numbers “3” and “4”.
Therefore, in the case of the control board storage box 310 of the present embodiment,
Four seals can be performed.

The spare sealing screws 338 to 338 are
Since it is temporarily fixed to each sealing portion 337, the sealing screw 338 can be used immediately for sealing when sealing. Therefore, it is possible to save time and effort for preparing the sealing screw 338 when sealing, and to prevent the sealing screw 338 from being lost. Since the spare sealing screw 338 is temporarily fixed with its tip clamped in the screw insertion hole 345, the spare sealing screw 338 does not fall off due to vibration or the like during transportation of the pachinko machine.

Also, depending on the sealing number, the sealing portions 337-33
Since the sealing order of No. 7 is clearly displayed, the sealing order can be easily managed by the hall manager or the like, and as a result, an illegal remodeling action can be easily found.

For this reason, when the cover body 2 is superimposed on the case body 1, the cover body 2 is guided by the guide portion 20 and the positioning projection 11, and moves straight against the elastic force of the locked portion 19. The locking part 10 and the locked part 19 are smoothly engaged with each other by eliminating the escape behavior of the cover body 2, and
Can be easily locked to the case body 1 and
In the state where the locking portion 10 and the locked portion 19 are engaged with each other, the escape behavior of the cover body 2 in the direction in which the engaged state is released can be prevented by the guide portion 20 and the positioning protrusion 11. It is possible to strengthen and stabilize the engagement state between the stopping part 10 and the locked part 19.

Further, the relative position between the case body 1 and the cover body 2 can always be regulated by the guide portion 20 and the positioning projection 11, and the cover body 2 can be locked to the case body 1.

Further, since the locking portion 10 and the locked portion 19 are engaged with each other at a position avoiding the wiring electrical components of the control board 3, the wiring to the control board 3 is connected to the locking portion 10 and the locked portion. 1

[Second Modification] FIG. 19 shows a second modification.
This will be described with reference to the explanatory diagram of FIG. Since the second modified example is a partial modification of the first modified example, the modified part will be described in detail, and the parts that are considered to have the same or substantially the same configuration as the first modified example will be assigned the same reference numerals. Therefore, duplicate description will be omitted. In the third modified example described later, the same description will not be repeated. In the second and third modifications, the second slit hole 47 in the first modification is excluded.

In this modified example, as shown in the front view of FIG. 19B and the perspective view of FIG. A screw member, also called a shavis, having an engagement portion 55 that engages with the operation member and a constricted portion 56 that is sheared by a predetermined or more tightening force of a rotation operation member such as a driver is used.

As shown in the sectional view of FIG. 19A, the fastening screw 53 is inserted into the insertion hole 42 of the cylindrical portion 42 of the cover 2.
a and the attachment hole 33a of the attachment boss 33 of the case body 1 through the insertion hole 3a of the control board 3 to fasten the case body 1 and the cover body 2. When the fastening is completed and a predetermined or more tightening force is applied to the constricted portion 56 by the rotating operation member, the constricted portion 56 is sheared, and FIG.
As shown in (d), the engaging portion 55 is separated from the screw 53 side. Then, as shown in FIG. 19A, the engagement portion 55 is eliminated from the fastening screw 53, and only the mountain-shaped head 54 remains, so that the fastening release operation on the head 54 cannot be performed. According to the present modified example, it is not necessary to provide a fastening release preventing means for another component such as the plug 41 as in the first modified example, so that the number of components can be reduced.

As shown in an exploded perspective view of FIG. 22, the fastening screw 53 is provided in a ROM 70 mounted on a control board.
Can be used when the cover 72 is attached to the IC socket 71. In this case as well, after the cover 72 is attached, the fastening release operation for the fastening screw 53 cannot be performed as described above, so that it is difficult to remove the cover 72, and it is possible to prevent unauthorized modification of the ROM 70.

[Third Modification] FIG. 20 shows a third modification.
This will be described with reference to the explanatory diagram of FIG. As shown in the cross-sectional view of FIG. 20 (a), the joint surface between the case body 1 and the cover body 2 is welded all around or partially by ultrasonic heating welding. Reference numeral 58 is written on the welded portion.

In place of the fastening screws 40 and 53, FIG.
The connection pin 60 shown in the front view is used in FIG.
The connecting pin 60 is formed of a shaft member with a head having a concave portion 62 at the tip of the shaft portion 61. The shaft portion 61 has a shaft diameter d _{1 which} is slightly larger than the hole diameter d of the mounting hole 33 a of the mounting boss portion 33 of the case body 1.
a is the the hole diameter d of the mounting hole 33a is substantially equal shaft diameter d _2, also the recess 62 is formed with a smaller shaft diameter than shaft diameter d ₂ of the tip end shaft portion 61a (reference number omitted). The head 63 of the connecting pin 60 has a disk shape and its upper end surface is flat.

As shown in FIG. 20A, the connecting pin 60 is inserted through the through hole 42a of the cylindrical portion 42 of the cover 2 and through the through hole 3a of the control board 3 to form the mounting hole of the mounting boss 33 of the case body 1. When inserted into the head 33a, ultrasonic vibration is applied to the head 63 by an ultrasonic vibrator (refer to a two-dot chain line in the figure) 65 of the ultrasonic heating welding machine. As a result, the connection pin 60 is inserted while the resin around the mounting hole 33a of the case body 1 is melted. As a result, the case body 1 and the cover body 2 are fastened inseparably and the recess 62 of the connection pin 60 Part of the resin by heat welding flows in and hardens.

According to this modification, the welded portion 58 of the joint surface between the case body 1 and the cover body 2 and the welded portion of the connecting pin 60 to the mounting boss 33 of the case body 1 are non-separably connected by heat welding. Therefore, in order to illegally remodel the control board 3, it is necessary to break the joint portion by the heat welding. Therefore, even if it is improperly modified, a trace of the destruction of the joint portion clearly remains. Therefore, unauthorized modification of the control board 3 can be more reliably prevented than in the related art.

Further, since the heat welding is ultrasonic heating welding, heat is generated only in the welding portion during the welding operation and the other portions hardly become hot, so that the danger of burns can be avoided.

Further, the resin flows into the concave portion 62 of the connecting pin 60 and is hardened, so that the case body 1 and the cover body 2 can be firmly fixed as compared with a connecting pin having no concave portion 62. The connecting pin 60 corresponds to the connecting member according to the present invention. In addition to the above, as shown in the front view of FIG. 21, the connecting pin 60 may be formed by forming a concave portion formed by a knurl 64 on the outer peripheral surface of the shaft portion 61.

The connection by the welded portion 58 of the joint surface between the case body 1 and the cover body 2 and the connection using the connecting pin 60 can be adopted as independent connecting means.

In this modified example, similarly to the fourth modified example, first, the control board 83 is attached to the cover 82 with the mounting screws 114.
After that, the cover body 82 is attached to the case body portion 81 of the accessory protection cover 118 by the fastening screw 53 (see FIGS. 31 and 32). Therefore, according to this modified example, the same operation and effect as those of the fourth modified example can be obtained. According to this modification, the case body 8 according to the fourth embodiment is provided.
1 is unnecessary, so that the number of parts and the number of assembling steps can be reduced. Further, since the electrical connection with the symbol display device 120 and the like is made simultaneously with the attachment of the cover body 81, the number of wiring work steps can be reduced. Further, the case body 81 may be formed integrally with the back mechanism plate instead of the accessory protection cover 118.

The present invention is not limited to the above-described modified example, and can be modified without departing from the gist of the present invention. For example, an adhesive may be used as the connecting means. The fastening screw 40 can be replaced with a bolt as a fastening means. In addition, as the fastening release preventing means, an adhesive injected into the cylindrical portion 42 and hardened may be used in addition to the plug 41. Further, the first support portion 45 can be provided on the case body 1 side, or can be provided on both the case body and the cover body 2. Further, the first support portion 45 and the second support portion can also be obtained by forming a thin portion. Further, the first support portion 45 and the second support portion can also be obtained by forming a thin portion.

In addition to 0, a bolt, a screw, or the like can be used.

[Sixth Modification] Next, a sixth modification will be described with reference to FIGS. As shown in FIGS. 33 and 34, a control board storage box 210 made of a synthetic resin in this pachinko machine includes a case body 212 for storing the control board 211, and a cover attached to the case body 212 and covering the control board 211. And a body 213. As is well known, the control board storage box 210 is detachably connected to a back cover (not shown, specifically, an accessory protection cover or a back mechanism plate) which is attached to the back of the game board of the pachinko machine. It is installed behind the game board. A front view of the case body 212 is shown in FIG.

As shown in FIG. 35, the case body 212
It has a substantially square plate shape and has a side wall 212
a. Bosses 214 each having a pilot hole 214a are formed at four corners of the case body 212, respectively. The boss 214 at the lower left in FIG.
Are set as reference boss portions for fixing the cover, and the remaining boss portions are set as mounting boss portions for fixing the substrate.

A pair of upper and lower locking pins 215 project from the left and right side surfaces of the case body 212, respectively. The locking pins 215 are respectively engaged with engagement holes (not shown) of left and right set plates 216 (see a two-dot chain line in FIG. 33) arranged on the back cover of the game board. With the engagement between the locking pin 215 and the set plate 216, the control board storage box 210 is supported by the back cover of the game board.

As shown in FIGS. 33 and 34, a control board 211 is housed in the case body 212 with almost no gap. The control board 211 has a mounting surface 211a as a surface,
The back surface is a solder surface 211b. The mounting surface 211
In a, components such as a RAM, an IC, and a fuse (not shown) are mounted in addition to the ROM 218 and the various connectors 219. A shield plate 220 made of a conductive material such as punched metal is interposed between the case body 212 and the control board 211 (see FIG. 34). The shield plate 220 blocks static electricity due to rolling friction of the pachinko ball or the like and prevents generation of noise due to the influence of the static electricity on the electronic components of the control board 211.

The control board 211 is fastened at its four corners by fixing screws 221 formed of tapping screws which are screwed into the prepared holes 214a of the bosses 214 of the case body 212. The fixing screw 221 at the lower left in FIG. 33 also serves as a cover fixing reference screw for fixing the cover body 213. The cover body 213 includes the control board 2
11 is formed in a substantially rectangular shape smaller than the case body 212 so as to expose the left edge and the lower edge thereof, and has a side wall 213a on the outer periphery thereof (see FIG. 34).
The tip of the side wall 213a forming the left side and the lower side of the cover 213 abuts on the control board 211, and the side wall 213 forming the upper side and the right side of the cover 213.
“a” forms a series of side walls with the side wall 212 a of the case body 212.

Control board 21 not covered by cover body 213
Various connectors 219 are arranged on one mounting surface 211a. The ROM 218 disposed on the mounting surface 211a of the control board 211 is covered with a rectangular box-shaped ROM cover 223 by fitting, and further covered by a cover body 213. The upper surface of the ROM cover 223 is in contact with the cover 213.

A recess 224 is provided in the side wall 213a forming the left side surface of the cover body 213. Recess 22
In FIG. 4, a heat radiating member (heat sink) 225 to which a heat source such as a power transistor on the control board 211 that generates a large amount of heat is attached is exposed, and the heat radiating effect is enhanced. Further, the control board storage box 2 is provided on the cover body 213.
Small-diameter heat-dissipating hole 2 for releasing heat generated inside 10
26 are open.

As shown in FIG. 33, a sticker 227 for attaching a model name sticker is provided at the center of the front surface of the cover body 213. Further, a mounting hole 228 for a probability change key switch is provided in the lower right part of the front of the cover body 213. The ROM 21 is located at the upper right of the front of the cover body 213.
A portion 229 for attaching a serial number sticker is set in a portion (see FIG. 35) located above the reference numeral 8.

The side walls 212a and 213a forming a series of the case body 212 and the cover body 213 are alternately fitted when the case body 212 and the cover body 213 are connected. More specifically, as shown in an exploded perspective view showing the fitting structure of the case body 212 and the cover body 213 in FIG. 42, the outer edges of the side wall 212a of the case body 212 and the side wall 213a of the cover body 213 are well represented. The projections 231 and the fitting recesses 232 are formed alternately in a concave and convex shape. When the case body 212 and the cover body 213 are connected, the projections 231 and the fitting recesses 232 are fitted to each other. The side walls 212a and 213a are connected in a series.

As shown in FIG. 33, the cover body 213 has a total of four,
A plurality of positioning holes 233 are formed. Positioning hole 2
33 is formed in a so-called concave shape with a bottom that does not penetrate. This is for the purpose of minimizing the intrusion of foreign matter into the control board storage box 210, and the positioning holes 233 are provided.
Prevent unauthorized remodeling by wire or the like.

On the other hand, on the lower surface of the case body 212, the positioning projections 2 located on the same axis as the positioning holes 233 are provided.
34 protrudes (see FIG. 34). For this reason, for example, when a plurality of control board storage boxes 210 are stacked, the positioning protrusions 234 of the upper control board storage box 210 engage with the positioning holes 233 of the lower control board storage box 210, whereby control is performed. Load collapse of the substrate storage box 210 can be prevented. This is effective when the control board storage box 210 is transported, when the pachinko machine is stored in an assembly factory, or the like. Further, when the control of the pachinko machine is complicated and the area of the control board 211 needs to be increased, if one control board 211 is used to cope with the problem, the pachinko machine can be accommodated in a limited space on the back side of the pachinko machine. Since it becomes difficult, it is conceivable to use the control board 211 divided into a plurality of parts. In this case, the same control board storage box 210 is stacked on the pachinko machine without forming a special control board storage box 210. When mounting, the positioning hole 233 and the positioning protrusion 23
This is advantageous because the positioning function by the engagement with the fourth member 4 can prevent the positional deviation between them.

The positioning projection 234 prevents the collapse of the load when the control board storage boxes 210 are stacked, and also allows the control board storage box 210 to be attached to the back surface (specifically, a protective cover or the like) of the pachinko machine. It also has a function of securely holding the control board storage box 210 when it is mounted via the connector. That is, usually, since the set plate 216 has flexibility, when the positioning protrusion 234 is not provided, the set plate 216 is bent by an external force from the lateral direction (the horizontal direction in FIG. 33) of the control board storage box 210. Control board storage box 21
0 may come off the protective cover or the like. For this reason, a hole for engaging with the positioning protrusion 234 is provided on the protection cover or the like, and the positioning protrusion 234 is engaged with the hole of the protection cover when the control board storage box 210 is attached to the protection cover or the like. Storage box 2
10 can be prevented from falling off due to external force in the lateral direction.

As shown in FIG. 33, an appropriate number of sealing portion groups 236 are arranged on the side surface of the control board storage box 210. In the present embodiment, the sealing unit groups 236 are set at a total of three places: the upper central part, the lower right part, and the lower left part of the control board storage box 210. Each sealing section group 236 includes a plurality (four in the figure) of sealing sections 237 that can be sealed by sealing screws 238. Each seal group 236
33 have the same configuration, the sealing unit group 236 at the lower right in FIG. 33 will be described in detail with reference to FIGS. 36 to 41, and the description of the other sealing unit groups 236 will be omitted. 36 is a front view of the sealing portion group, FIG. 37 is a cross-sectional view showing a sealing state of the sealing portion, FIG. 38 is a cross-sectional view showing a temporary fixing state of the sealing screw, FIG. 39 is an exploded cross-sectional view of the sealing portion, and FIG. Is a front view of a sealing section group showing a sealing number, and FIG. 41 is an explanatory view of a sealing screw.

Before explaining the sealing portion 237, the sealing screw 23
7 will be described with reference to FIG. In FIG. 41, a sealing screw 238 is a one-way type screw that can be tightened but cannot be loosened, (a) is a plan view of the sealing screw, (b) is a front view, and (c). Is the bottom view,
(D) is a sectional view of the screw thread. As shown in FIGS. 7A to 7C, the sealing screw 238 has a shaft portion 239 having a thread 239a on the outer periphery and an engaging hole 240a on the upper surface for engaging with a rotating operation member such as a cross driver. And a head 240. The engaging hole 240a of the head 240 engages in the direction of tightening the rotating tool (see the direction of arrow A in the figure (a)) by a cross driver or the like, and conversely, in the loosening direction (in the figure (a)). (See the direction of arrow B)). Also, the thread 239a of the shaft portion 239
Has four circles on the circumference as shown in FIGS.
The groove portions 239b are formed so as to intersect with the thread 239a. The thread angle of the thread 239a is shown in FIG.
As shown in FIG.

The sealing screw 238 having the above-described structure enables the rotary tool to be tightened, while engaging the head 240 in the loosening direction of the rotary tool (see the arrow B direction in FIG. 41A). Thread 23 in the loosening direction to reduce the resultant force
By increasing the rotation resistance of 9a, removal from the tightened state becomes impossible. For such a sealing screw 238, for example, Gizatite, part number GTP3XL (trade name, manufactured by Nitto Seiko Co., Ltd.) can be used, or Japanese Unexamined Utility Model Publication No. 59-47114,
It is also possible to substitute the screw disclosed in -103607.

Next, the sealing section 237 will be described. As shown in FIG. 39, on the side wall 212a of the case body 212,
A sealing boss 242 having a bottomed pilot hole 242a is formed in a protruding manner via an opening 242b. A sealing fastening portion 244 corresponding to the sealing boss portion 242 of the case body 212 is formed on the side wall 213a of the cover body 213 so as to protrude via an opening portion 244b. Each opening part 2
Reference numerals 42b and 244b are formed to be thin in a neck shape, and can be cut by a cutting tool such as a nipper or a cutter. Further, on the mating surface of the sealing boss portion 242 and the sealing fastening portion 244, there is provided an engaging means comprising a circular engaging convex portion 246a and an engaging concave portion 246b which are fitted to each other.

The seal fastening portion 244 is formed in a substantially cylindrical shape, has a screw hole 244a at the lower end in the drawing, and has a screw holding portion 247 at a portion above the screw hole 244a in the drawing. I have. In the upper half of the screw holding part 247,
Two slits 248 are formed in the circumferential direction.
6). In Figure 39, d ₁ the outer diameter of the head 240 of the sealing screw 238, when the outer diameter of the shaft portion 239 and the d _2, the inner diameter D ₁ of the screw holding portion 247, the diameter D ₂ of the screw holes 244a, seal the inner diameter D of the prepared hole of the boss portion 242 ₃ is formed so as to satisfy the dimensional relationship of _{D 1 <d 1 D 2>} d 2 D 3 <d 2. Further, the sealing fastening portion 244 has a height capable of accommodating the sealing screw 238.

In the sealing fastening portion 244, by inserting the sealing screw 238 into the screw holding portion 247, the screw holding portion 247 is expanded by the head 240 of the sealing screw 238 so as to open between the slits 248. The head 240 is temporarily fixed by being held by the elasticity that resists the expansion (see FIG. 38). Then, the case body 212
Body 2 with the cover body 213 attached to the
Twelve sealing bosses 242 and the sealing fastening part 244 of the cover body 213 are located on the same axis through the fitting of the engaging projection 246a and the engaging recess 246b (see FIG. 38). Then, at the time of sealing, the sealing is performed by tightening the sealing screw 238 into the prepared hole 242a of the sealing boss 242 by a rotating tool (see FIG. 37).

As shown in FIG. 36, as shown in FIG.
The individual sealing portions 237 are sealing portions 237 for the first, second, third, and fourth times from the top to the bottom of the drawing.
The unsealing portion 244b of the cover 213 is provided with a sealing number 250 of “1, 2, 3, 4” indicating the sealing order.
Seal number 250 is well represented in FIG. When the control board storage box 210 is completely assembled, the sealing section 237 of the sealing number 250 of “1” of each sealing section group 236 is sealed by the sealing screw 238.
The sealing portion 237 of the sealing number 250 of “2, 3, 4” is a spare and is not sealed. The seal number 250 is
It can be attached by printing, engraving, resin molding die. In addition, Roman numbers, alphabets, symbols, and the like can be used as the seal numbers in addition to arithmetic numbers.

As shown in FIG. 36, a fine mesh pattern 251 is formed on the upper surface of the opening portion 244b of the cover body 213 by knurling together with the sealing number 250.
The mesh pattern 251 can be formed by a resin mold instead of knurling. Further, the shape of the mesh pattern 251 may be streaks or bevels in addition to the illustrated grids. The mesh pattern 251 and the sealing number 250 are also provided on the lower surface of the opening 242b of the case body 212 in the same manner as described above (not shown).

In the control board storage box 210 of the above-mentioned pachinko machine, the sealing portion 237 of the sealing number 250 of “1” of each sealing portion group 236 is formed by the sealing screw 238 for sealingly removing the case body 212 and the cover body 213.
Is sealed, so that unauthorized modification of the control board 211 can be prevented.

When the cover body 213 is to be removed for a valid reason in the case of an on-site inspection by an authority, etc., the sealing number 250 of “1” of the three sealing sections 236 is set.
By cutting the unsealing portions 242b and 244b, the cover body 21 is kept tight while the sealing screw 238 is tightened.
3 can be easily removed. Thus, the mounting surface 211a of the control board 211 can be inspected. When opening the sealing section 237, the opening section 2 of the cover body 213 is opened.
At least one of 44b and the opening portion 242b of the case body 212 may be cut.

The screw holding section 2 of the sealing section 237 of the sealing number 250 of “2” in the three sealing section groups 236 is also provided.
If the sealing screw 238 temporarily fixed to 47 is fastened to the sealing boss portion 242 with a rotating tool to seal, the control board storage box 210 can be reused. By repeating the above, sealing can be performed again in the order of “3” and “4” of the sealing number 250. Therefore, in the case of the control board storage box 210 of the present embodiment, sealing can be performed four times.

According to the control board storage box 210 described above, the sealing screw 238 is temporarily fixed to the sealing portion 237 in advance as shown in FIG. 38, whereby the sealing screw 238 is used immediately for sealing. Can be. Therefore, it is possible to save the trouble of preparing the sealing screw 238 for sealing and to prevent the sealing screw 238 from being lost.

Since the sealing screw 238 is temporarily fixed and held by the elasticity of the screw holding portion 247, the temporary fixing operation of the sealing screw 238 can be performed more easily and the sealing screw 238 can be inserted as compared with the temporary fixing and holding by screwing. Even if it drops, it can be easily pushed back.
The position management for temporary fixing can be easily performed.

Also, the slit 248 of the screw holding portion 247
Is cut in the middle, and when the head 240 of the sealing screw 238 is in the slit 248, tightening is performed with little resistance. In the final stage of tightening (see FIG. 37), the outer part is smaller than the head 240. Due to the diameter, it will be tightened with a large torque. Therefore, even if the tip of a rotating tool such as a screwdriver is glued to the sealing screw 238 with an adhesive or the like, and the sealing screw 238 is cleverly loosened, a resistance sufficiently larger than the adhesive force can be secured.
The loosening of the sealing screw 238 can be reliably prevented.

In the screw holding portion 247, when the sealing screw 238 is temporarily fixed with only the cover member 213, the sealing screw 238 is temporarily inserted too deeply,
Even when the tip of the sealing screw 238 protrudes from the lower surface of the case 44, when the cover body 213 is attached to the case body 212 in a subsequent step, the sealing screw 238 is provided at the upper end of the prepared hole 242a of the sealing boss 242 of the case body 212. The sealing screw 238 is pushed back upward,
It does not affect the assembly work of the control board storage box 210.
Further, even when the sealing screw 238 is temporarily fixed after the cover body 213 and the case body 212 are assembled, the sealing screw 2
Since the tip of the sealing screw 238 is lightly press-fitted from above, the front end of the sealing boss portion 242 of the case body 212 is
Since it does not come in contact with the upper end of a, the temporary fixing work of the sealing screw 238 can be easily performed manually.

In the manufacturing process, the sealing screw 238 may be temporarily fixed to all the screw holding portions 247 with only the cover 213 or may be screwed after the cover 213 and the case 212 are combined. Holder 247
May be temporarily fixed.

Further, the sealing portion 237 is designated by the sealing number 250.
Since the sealing order is clearly displayed, the sealing order can be easily managed by a hall manager or the like, and an illegal remodeling action can be easily found.

For the purpose of unauthorized modification, the opening portions 242b and 242b
When the 44b is cut, the mesh pattern 251 is damaged by the opening, and the repair of the damaged mesh pattern 251 becomes technically difficult. it can. Opening section 242
b, 244b, seal number 250 with mesh pattern 251
Since the seal number 250 cannot be read due to the opening, it is easy to detect an unauthorized modification.

The R in the control board storage box 210
The OM 218 is surrounded by the ROM cover 223 as shown in FIG. 34, and the upper surface of the ROM cover 223 is in contact with the cover body 213. Therefore, the mating surface between the case body 212 and the cover body 213 is pryed open with a screwdriver or the like. It is possible to prevent an unauthorized remodeling attempt to be performed on the ROM 218 through the gap. ROM cover 2
The shape 23 may be such that there is no gap between the control board 211 and the cover body 213. For example, in the case of the above-mentioned form, the shape 23 can be easily attached by fitting it into the ROM 218. When there are few circuit elements and wires on the control board 211 and there is ample space around the ROM 218, the ROM cover 223 can be formed in a cylindrical shape or an elliptical cylindrical shape.

Further, since the series of side walls 212a, 213a are formed by fitting the projecting pieces 231 of the case body 212 and the cover body 213 and the fitting recesses 232, the side walls 212a, 213a receive external force. Even if it is hard to be distorted. Therefore, the side walls 212a and 213a
Is pressed to create a gap between the cover body 213 and the case body 212, there is no gap, so that an unauthorized remodeling attempt to insert a foreign object such as a wire through the gap to prevent the gap can be prevented.

The upper end position of the portion (left portion in FIG. 34) of the side wall 212a of the case body 212 that does not abut against the side wall 213a of the cover body 213 is
Since it is located at a position higher than the contact position between the control board 211 and the side wall 213a, it becomes difficult to insert foreign matter such as wire into the control board storage box 210 from between the side wall 213a of the cover body 213 and the control board 11. This is also effective in preventing unauthorized modification.

[Seventh Modification] FIG. 43 shows a seventh modification.
This will be described with reference to FIG. Since the seventh modified example is a partial modification of the sixth modified example, the modified part will be described in detail, and the other redundant description will be omitted. Also, in the modified examples after the third embodiment, the same explanation will not be repeated.

In this embodiment, the temporary fixing structure of the sealing screw 238 of the sixth modification is modified. 43A is a plan view of a screw holding portion, and FIG. 43B is a cross-sectional view of a sealing portion. As shown in FIG. 43, four slits 248 of the screw holding portion 247 are provided in the circumferential direction. By increasing the number of the slits 248 of the screw holding portion 247 in this manner, the elastic force of the screw holding portion 247 can be reduced, and the sealing screw 238 can be inserted into the screw holding portion 247 lightly. The slit 2 of the screw holding part 247
The number of 48 is not limited and is appropriately selected.

[Eighth Modification] FIG. 44 shows an eighth modification.
This will be described with reference to FIG. In the present embodiment, the temporary fixing structure of the sealing screw 238 according to the seventh modification is modified. FIG.
3A is a plan view of a screw holding portion, FIG. 3B is a cross-sectional view of a sealing portion, and FIG. 3C is a plan cross-sectional view of a screw hole portion. As shown in FIGS. 44A and 44B, an appropriate number (four are shown in the figure) of retaining protrusions 253 protruding inward are formed at the upper end of the screw holding portion 247. FIG.
As shown in (c), an appropriate number (three are shown in the figure) of support protrusions 254 are formed on the inner peripheral surface of the screw hole 244a.

As shown in FIG. 44B, the relationship among the diameter D ₁ of the screw holding portion 247, the diameter D ₄ of the opening of the retaining projection 253, and the diameter D ₅ of the opening of the support projection 254 is as follows. It is formed so as to satisfy the dimensional relationship of D ₁ ≧ d ₁ D ₄ <d ₁ D ₅ <d ₂ . Note that d ₁ is the outer diameter of the head 240 of the sealing screw 238, and d ₂ is the shaft 239.
(See FIG. 39).

In the screw holding portion 247, when the sealing screw 238 is inserted into the screw holding portion 247, the head 240 of the sealing screw 238 hits the retaining protrusion 253 of the screw holding portion 247, and the screw holding portion 247 is expanded. And
When the sealing screw 238 is stored in the screw holding portion 247,
The screw holding portion 247 is restored to the original state, and the sealing screw 238 is restored.
Is temporarily held in a state where it is prevented from coming off. Further, the stored sealing screw 238 is supported by the support protrusion 2 of the screw hole 244a.
54 prevents further lowering. When the sealing screw 238 is tightened, the support protrusion 254 is crushed by the thread 239 a of the sealing screw 238.

According to the temporary fixing structure of the sealing screw 238 described above, the sealing screw 238 is temporarily held by being stored in the screw holding portion 247 in a retaining state. , 2)
Since no stress is applied to the screw holding portion 247 during the holding of the sealing screw 238, there is no possibility that the holding force of the sealing screw 238 decreases, and the temporary fixing state can be continued for a long time.

Further, by providing the support protrusion 254 for preventing the sealing screw 238 from descending in the screw hole 244a, it is possible to suppress an increase in the tightening torque of the sealing screw 238 at the time of sealing. For example, by setting the diameter D ₂ of the screw hole 244a and the outer diameter d of the shaft portion 239 of the sealing screw 238 to be D ₂ <d ₂ , the descent of the sealing screw 238 can be prevented. threaded torque becomes large, but by providing the partial support protrusions 254 on the inner peripheral surface of the screw hole 244a of the D _2> d _2, thereby suppressing the increase of the tightening torque.

If the diameter D ₂ of the screw hole 244a and the outer diameter d ₂ of the shaft portion 239 of the sealing screw 238 satisfy D ₂ > d ₂ and the support projection 254 is not provided, the cover 213 is not provided. Inserting the sealing screw 238 in the state of only
The tip of the shaft 239 of the sealing screw 238 has a screw hole 244a.
