Description

  The present invention relates to a board storage case of a gaming machine.

  Generally, a gaming machine installed in a hall (game room) or the like has a game board for playing a game on the front side of the gaming machine and a game control circuit for controlling the gaming machine on the back side of the gaming machine. As such gaming machines, there are pachinko machines, slot machines, and the like. In this specification, the gaming machines are described as pachinko machines for convenience.

  As is well known, the game control circuit has a main control board (hereinafter also referred to as “main board”) as a game control board for controlling the main game operation of the gaming machine, and a subordinate relationship with the main control board. And the sub-board.

  Each of these main boards and sub-boards is provided with a central processing unit CPU, a random access memory (RAM) as a write storage element, and a read only memory (ROM) as a read only storage device. It operates with the command of.

On the main board, various random values such as jackpot random numbers are mainly written by the RAM, and a random number determination program by the ROM and other various programs are stored.
In the main board, various data setting processing, random number update management processing, various symbol management processing, lamp management processing, prize ball payout management processing, command transmission management processing, and other various processing for operating the gaming machine are performed. .

  In addition, the sub-board includes a symbol control board that performs symbol control, a lamp control board that lights or blinks a panel lamp or a frame lamp, an audio signal control board that controls various sounds emitted from a speaker, and a prepaid card unit. In addition, there are a payout control board and other various control boards for controlling the lending ball payout device, and these sub boards usually function by receiving various command signals from the main board.

Therefore, the main board is an extremely important part in game execution.
Therefore, if the legitimate program for the main board is altered by a third party to become a so-called back board, there is a risk that a jackpot will be illegally allocated. Therefore, in order to prevent this, these control boards, in particular, main boards provided with a program for determining jackpot random numbers are covered with a case body.
JP 2000-308743 A JP 2000-140352 A Japanese Patent Laid-Open No. 10-17984 JP-A-9-266973 Japanese Patent Laid-Open No. 10-225560 Japanese Unexamined Patent Publication No. 2000-140336 JP-A-10-57577 JP 2000-350845 A Japanese Patent Laid-Open No. 11-33194

On the other hand, many components disposed on the main board generate heat. For this reason, the case body covering the main substrate tends to be hot. In order to prevent this, the case body is usually provided with a heat radiating hole.

  By the way, although this heat radiating hole is a fine hole from the viewpoint of security, it is still illegal to use an IC clip, a wire, or the like through this hole because of its communication with the substrate inside the case. There is a fear.

Therefore, as a technique for preventing such injustice, for example, Japanese Patent Application Laid-Open No. 10-17984 discloses a technique in which a discharge hole is eliminated.
In this technique, a heat radiating member is attached to a main substrate in a contact state, and a part of the heat radiating member is exposed to the outside of the case, thereby releasing the heat in the case to the outside.

  The case is partially cut away so that the heat dissipation member can be exposed to the outside of the case. Therefore, when the main board is covered with a case, a gap is formed between the notch portion of the case and the heat radiating member. For this reason, there is no denying the possibility that the cheating is performed through the gap.

  The present invention has been made to solve the above-described conventional problems, and a problem to be solved is to provide a technique capable of further preventing fraud and further enhancing the heat dissipation effect. .

In order to achieve the above object, the storage case of the gaming machine of the present invention employs the following means.
That is, the board storage case of the gaming machine of the present invention is a board storage case for storing a game control board for controlling the gaming operation of the gaming machine, and the board storage case includes a game control board stored in the board storage case. a heat radiating portion for radiating generated from disposed the parts heat outside of the case, provided a protruding portion protruding case the space portion as a part of the board housing case, the control board to the protrusion those The projecting portion is a hollow body at least one end of which faces the outside air, and the inner surface in the hollow portion of the projecting portion has a step or
A kerf is formed .

  In the board storage case of the gaming machine of the present invention, a heat radiating part for radiating the heat generated from the heat generating components arranged on the control board to the outside of the case is provided as a protruding part protruding into the space in the case, and the protruding part controls Since the substrate is brought into contact, even if the temperature inside the case, particularly the temperature of the control board on which the heat-generating component is placed, increases due to the heat generated from the components disposed on the control board, And it comes to be discharged to the outside of the case via the protrusion. For this reason, the temperature in the case can be lowered without forming a gap or a heat radiating hole in the case. In addition, since the protruding portion which is a heat radiating portion protrudes into the space inside the case but does not protrude outside the case, the heat radiating portion does not interfere with the work when the board storage case is attached to the gaming machine.

The substrate storage case including the protruding portion may be formed by injection molding, or an insert embedded by insert molding may be used as the protruding portion .

Before SL insert is preferably a metal material, for example, relatively high aluminum thermal conductivity is preferred.

Before SL increments, relative to the axial direction of the protruding portion may be formed in parallel to or obliquely.
The kerf can also be formed in a spiral shape.

The step and the cut groove may be formed on the outer surface of the protrusion .
A board storage case for storing a game control board for controlling a gaming operation of a gaming machine and having an upper and lower divided structure composed of an upper case and a lower case, wherein at least one of boundary portions between the upper case and the lower case It is also conceivable to form a slit portion extending in the peripheral direction of the case in the portion, and attach a heat radiating member having an H-shaped cross section to the slit portion.

In this case, it is preferable that the heat radiating member is sandwiched between the upper and lower cases with a web portion of the heat radiating member having the H-shaped cross section interposed in the slit portion.
Thus, the board storage case of the gaming machine of the present invention is in a state in which the web portion of the H-type heat radiating member is sandwiched between the slit portions, so that the web portion of the H-type heat radiating member is interposed in parallel. The wall surface and the wall surface of the substrate storage case are substantially in parallel both outside and inside the case. When this state is visually confirmed in the cross section of the heat radiating member, the cross section of the groove formed between the wall surfaces of the H-type heat radiating member has a cup shape, and the wall surface of the substrate storage case has a bar shape in the cross section. Visible as if presenting. For this reason, the shape of the cross section which combined both can be visually recognized as a form which inserts the rod from the opening side in the said cup-shaped groove part. Therefore, between the both wall surfaces of the H-type heat radiating member and the side wall of the substrate storage case, (1) the gap from the opening shape side to the bottom shape side in the cup-shaped groove, and (2) the bottom shape side A series of gaps having a bent portion in the middle of the cup-shaped groove portion and a gap from the bottom shape side to the opening shape side of the cup-shaped groove portion. Become.

  However, this gap is a gap having the bent portion in the middle, unlike a simple single hole whose center line is on the same axis. Therefore, even if a foreign object such as an IC clip or a wire is illegally inserted from the outside of the gap, the foreign object hits the bent portion of the gap, so that it is difficult to further insert the foreign object through the gap.

  Further, the series of gaps having the bent portion is formed by fitting the H-type heat radiating member at the slit portion of the substrate storage case. Therefore, the insertion of foreign objects such as IC clips and wires can be made more difficult as the gap is reduced by setting the dimension between both wall surfaces of the H-type heat radiation member and the wall thickness of the side wall of the substrate storage case so that the gap becomes smaller. Although it is preferable, it becomes difficult to fit the H-type heat radiating member into the slit portion of the substrate storage case. Therefore, even if a clearance fit with a large gap is set to fit the H-shaped heat radiating member into the slit portion of the substrate storage case, the series of gaps are bent, so an IC clip, a wire, etc. Foreign object insertion is still difficult. Therefore, even if it is a clearance fit state, it is effective in preventing fraud.

It is desirable that the heat dissipation member and the game control board are separated.
When both are integrated, the weight of the heat radiating member is applied to the game control board. Therefore, concentrated stress may be generated on the game control board depending on the location of the heat dissipation member on the game control board. However, if the heat radiating member and the game control board are separated from each other and are separated from each other, there is no risk of concentration stress resulting from assembling the heat radiating member to the game control board.

The upper and lower cases are preferably made of a transparent material.
In this case, when a foreign object such as an IC clip or a wire is inserted as a fraudulent act, the discovery of the scratches that can be made on the upper and lower cases at that time can be easily seen from the outside of the case.

  Therefore, when it is determined that an illegal act has been made, it is possible to take a countermeasure immediately.

  The present invention further enhances the further prevention of fraud and the heat dissipation effect.

Hereinafter, a specific embodiment of a gaming machine to which a board storage case of the gaming machine of the present invention is applied will be described based on the attached drawings.
(Example)
First, the outline of a gaming machine to which the board storage case of the gaming machine of the present invention is applied will be described as a pachinko gaming machine, and the board storage case of the gaming machine of the present invention will be described in turn.

However, as long as it is a gaming machine having a substrate storage case, it is not limited to a pachinko gaming machine, and may be a slot machine or other gaming machines.
FIG. 1 is a perspective view of the pachinko gaming machine I as seen from the front side, and FIG. 2 is a perspective view of the pachinko machine I as seen from the back side.

The pachinko gaming machine I shown in this embodiment corresponds to a prepaid card system, and is provided with a prepaid card unit II adjacent to it.
The prepaid card unit II includes a card reader 29 therein, and the player inserts the prepaid card 35 purchased before the game is executed into the reading port 33 of the card reader 29 to execute the pachinko game. Get ready.

  Further, on the surface of the game board 1, a guide rail (not shown) for guiding a ball launched by the operation of the operation handle 28 as a launching device to the game board 1 is planted in a substantially circular shape. The defined area constitutes the game area 3.

A variable display device 30 that variably displays identification information (hereinafter referred to as “symbol”) such as numbers, symbols, and patterns is disposed at substantially the center of the game area 3 (see FIG. 1).
The variable display device 30 variably displays several kinds of symbols indicated by the symbols 32a, 32b and 32c on the left side, the center and the right side, stops the changing symbols, and determines the symbols when the symbols are stopped. When the symbols are matched and matched, a symbol display device 32 is displayed to display that a predetermined gaming state such as a jackpot is achieved. For example, a liquid crystal display device is applied to the symbol display device 32.

As is well known, the symbol displayed on the symbol display device 32 starts to change when a ball wins a winning prize opening. The starting winning opening is indicated by reference numeral 70.
Around the variable display device 30, a decoration LED, a panel lamp, a frame lamp, and other various electric decorations 80 and a speaker 42 for notifying the player of the number of reserved balls are arranged.

In the lower part of the game area 3, a special winning opening (hereinafter referred to as “attacker”) 90 that is opened for a certain period only when a big hit is arranged.
Thus, when the ball wins the start winning opening 70, various symbols displayed on the symbol display device 32 of the variable display device 30 start to change. When a certain period of time has elapsed after the start of fluctuation, the symbols 32a, 32b, and 32c stop changing in the order of left, middle, and right, the symbols are fixed, and the determined combination of symbols becomes a predetermined display mode. As a result, a specific gaming state (also called a big hit gaming state) is entered, and the attacker 90 is released for a certain period of time as described above, and a ball flowing to the attacker 90 among the balls falling on the surface of the game board 1 is received.

  A specific area (not shown) is provided inside the attacker 90, and the attacker 90 is released again when a ball wins the specific area. In the opening, a continuation right is established every time a ball wins in the specific area, and a predetermined round is performed.

In addition, the pachinko gaming machine I of the present embodiment has a back ball prevention member,
A well-known pachinko gaming machine component is installed at the outlet. What is indicated by reference numeral 36 is a lending button for controlling a lending ball payout device (not shown), and what is indicated by reference numeral 38 is a return button for a prepaid card.

  Thus, when the ball has won the start winning opening 70 as described above, the determination as to whether or not the ball has won the jackpot is executed by the jackpot determination system provided in the pachinko gaming machine I.

  The jackpot determination system is a system that assigns a random number as a trigger when a ball wins the start winning opening 70. In other words, the jackpot determination system is a system that wins if the assigned random number is the same as the predetermined jackpot value, and the execution of the system is the main game control board of the pachinko gaming machine I. This is done by a program stored in the ROM of the control board.

The main board performs various data setting processing, random number update management processing, symbol management processing, lamp management processing, command transmission management processing, and other main processing for operating the pachinko machine.
There are also sub-boards that are in a subordinate relationship with the main board.

  The sub-board includes a symbol control board for controlling various symbols, a lamp control board for turning on or blinking the electric decorations 80 such as the panel lamp and the frame lamp, and an audio signal for controlling various sounds emitted from the speaker 42. There are a control board, a prepaid card unit II and a payout control board for controlling the lending ball payout device and other various control boards, and these sub-boards all operate by receiving various command signals from the CPU of the main board.

The main board and the various sub-boards are attached to the back side of the pachinko gaming machine I, and the various sub-boards are provided in the vicinity of the main board.
As described above, the main board is an important part for executing the jackpot determination of the pachinko gaming machine I. Therefore, if the main board is tampered with by a third party to become a back board, there is a risk that a jackpot will be illegally assigned. Therefore, in order to prevent this, the main board is covered with a board storage case 46 as shown in FIGS. In FIG. 4, what is indicated by reference numeral 44 is a main substrate.

The substrate storage case 46 is a case body having a rectangular shape with an upper and lower divided structure composed of a substrate storage case upper part (upper case) 48 and a substrate storage case lower part (lower case) 50.
The substrate storage case 46 is made of a transparent material such as transparent plastic. The substrate storage case 46 is formed by, for example, injection molding.

A slit 52 extending in the peripheral direction of the case is formed at least at a part of the boundary between the side wall 47 of the substrate storage case upper part 48 and the side wall 51 of the substrate storage case lower part 50.
As shown in FIG. 3 and FIG. 4, a web portion 56 having a rectangular cross section of a heat dissipating member (hereinafter referred to as “H type heat dissipating member”) 54 having a substantially H shape in the cross section is interposed in the slit portion 52. The H-type heat radiation member 54 is sandwiched between the substrate storage case upper part 48 and the substrate storage case lower part 50. The H-type heat radiating member 54 functions as a heat radiating portion that radiates heat generated from a heat generating component (not shown) disposed on the main board 44 to the outside of the board storage case 46.

In addition, the wall plates juxtaposed on both sides of the web portion 56 of the H-type heat radiation member 54 are denoted by reference numerals 55o and 55i.
Since the wall plate 55o is located outside the substrate storage case 46, it is hereinafter referred to as an outer wall plate, and the wall plate 55i is referred to hereinafter as an inner wall plate because it is located inside the substrate storage case 46.

Each cross section of both wall plates 55o and 55i has a flat deformed octagon.
Therefore, the H-shaped heat radiation member 54 is formed such that cup-shaped grooves 61u and 61d having a widening at the end of the cross section open to the upper side and the lower side, respectively, at the upper and lower sides of the web portion 56 are defined. Become.

  When the H-type heat radiation member 54 is interposed in the slit portion 52, the side wall 47 and the side wall 51 of the substrate storage case 46 are inserted into the groove portions 61u and 61d, respectively. In the groove 61u, a series of passage-shaped gaps 65u are formed between the outer wall plate 55o and the side wall 47, between the tip of the side wall 47 and the upper surface of the web portion 56, and between the inner wall plate 55i and the side wall 47. . Further, the gap 65u has bent portions 63u and 63u in the middle thereof.

  Similarly, in the groove 61d, a series of passage-shaped gaps 65d are formed between the outer wall plate 55o and the side wall 51, between the tip of the side wall 51 and the lower surface of the web portion 56, and between the inner wall plate 55i and the side wall 47. Is done. Further, the gap 65d has bent portions 63d and 63d in the middle thereof.

In practice, since the web portion 56 is placed at the tip of the side wall 51, it is difficult to form a gap between the tip of the side wall 51 and the lower surface of the web portion 56.
In FIG. 4, a hollow cylindrical pedestal 58 that supports the main control board 44 is provided at a proper position of the main wall 53 in which the side wall 51 protrudes from the periphery of the lower part 50 of the substrate storage case 50. As a part of 46, a plurality of protrusions are provided in the case internal space S (only one is shown in the drawing). Therefore, the gantry 58 can be referred to as a protruding portion.

  The main board 44 is attached to the gantry 58 by fitting it into a fitting hole 66 provided in the board housing case 46 with a projection 67 projecting upward from the top surface of the gantry 58 in a tight fit. As a result, the main board 44 is attached to the gantry 58 in a contact state.

  The pedestal 58 also functions as a heat radiating portion, like the heat radiating member 54. Therefore, the gantry 58 has a hollow 62 having an opening at one end facing the outside air at least on the side of the anti-projection portion 67 that is one end side thereof.

  Further, as shown in FIGS. 5 to 10, the substrate storage case 46 including the gantry 58 may be formed by insert molding. In the case of insert molding, a metal material is used as an insert, and the metal material is formed to be the mount 58. In addition, as a metal material, aluminum with high heat conductivity, for example, is suitable.

FIG. 5 is a cross-sectional view corresponding to FIG. 4 showing a gantry formed by insert molding. The frame of FIG. 5 is indicated by reference numeral 58A. The gantry 58A is shown as a first modification of the gantry 58.
In the gantry 58A shown in FIG. 5, the insert is made of metal and has a cylindrical shape with both ends opened.

  5 is different from the gantry 58 in FIG. 4 in that the main board 44 is fixed to the gantry 58A by a screw member 57 instead of the projection 67 provided on the gantry 58. And a female screw 59 as a kerf having a threaded relationship with the screw member 57 is cut in the hollow 62 (the surface of the hollow 62 of the pedestal 58A is formed in a spiral shape).

  Therefore, in the first modified example shown in FIG. 5, after the main board 44 is placed on the top surface of the gantry 58A, the screw member 57 is screwed into the female screw 59 of the gantry 58A, thereby the main board 44. Is fixed to the substrate storage case lower portion 50 of the substrate storage case 46.

  Next, a second modification of the gantry will be described with reference numeral 58B with reference to FIGS. 6 is a front view of the gantry 58B, FIG. 7 is a longitudinal sectional view thereof, FIG. 8 is a plan view thereof, and FIG. 9 is a transverse sectional view thereof.

  The difference between the gantry 58B according to the second modification and the gantry 58A according to the first modification is that a notch 75 is formed in a hollow of the gantry 58B by a known knurling instead of the female screw 59 of the gantry 58A. The female screw 59B that is screwed into the screw member 57 is formed only on the top surface of the mount 58B.

  Therefore, the above-described various mounts can further enhance the heat dissipation effect by forming the notches 75 or the internal threads 59 that are kerfs on the inner surface of the hollow 62 regardless of the type of material. The step 75 may be formed parallel to the axial direction of the gantry or may be formed obliquely with respect to the axial direction.

Next, with reference to the perspective view of FIG. 10, the 3rd modification of a mount frame is shown using the code | symbol 58C.
The difference between the gantry 58C according to the third modification and the gantry 58B according to the second modification is that a notch 75 is formed on the outer surface of the gantry 58C and a female screw 59B is formed in the hollow of the gantry 58C. In the point.

A kerf may be formed on the outer surface of the gantry 58 instead of the step. Further, notches and / or kerfs may be formed on both the hollow portion and the outer surface of the pedestal 58C.
In addition, the position and dimensions of the gantry 58 are set so that the H-type heat radiation member 54 and the main substrate 44 do not come into contact with each other when the main substrate 44 is supported by the gantry 58C, that is, the two are separated. Yes.

Next, the effect of the board storage case 46 having such a configuration applied to the pachinko gaming machine I will be described.
In the board storage case 46 installed on the back side of the pachinko gaming machine I, an H-type heat radiating member, which is a heat radiating part for radiating heat generated from the heat-generating components disposed on the main board 44 to the outside of the case 46 54 and a pedestal 58 are provided, and the following operational effects are obtained.

(1) H-type heat dissipation member 54
The H-type heat radiation member 54 is attached to the substrate storage case 46 in a state where the web portion 56 is sandwiched by the substrate storage case upper portion 48 and the substrate storage case lower portion 50 in the slit portion 52 of the substrate storage case 46. The outer wall plate 55o and the inner wall plate 55i of the H-type heat radiating member 54 are substantially parallel to the side walls 47 and 51 of the substrate storage case 46 outside and inside the substrate storage case 46, respectively.

  In other words, it can be visually recognized as an L-shaped rod body inserted from the opening side into the cup-shaped grooves 61u, 61d in cross section. That is, a series of gaps 65u defined by both wall plates 55o, 55i of the H-type heat radiation member 54 and the side wall 47 of the substrate storage case 46, and both wall plates 55o, 55i of the H-type heat radiation member 54 and the substrate A series of gaps 65d defined by the side wall 51 of the storage case 46 can be seen. However, the gaps 65u and 65d are different from a simple single hole whose center line is on the same axis, and have bent portions 63u, 63u and 63d, 63d, respectively. Even if illegal foreign substances such as clips and wires are inserted, these foreign substances hit the bent portions 63u, 63u and 63d, 63d. Therefore, it becomes difficult to insert a foreign substance into the substrate storage case 46 via the gaps 65u and 65d.

The series of gaps 65u and 65d is formed by fitting the H-type heat radiation member 54 with the slit portion 52 of the substrate storage case 46. Therefore, the smaller the gaps 65u and 65d, the more difficult it is to insert foreign matter such as IC clips and wires, which is preferable. In this case, the H-type heat radiation member 54 is fitted into the slit portion 52 of the substrate storage case 46. It becomes difficult.

  In order to fit the H-type heat radiation member 54 into the slit portion 52 of the substrate storage case 46, it is conceivable to set a clearance fit with a large gap. The gaps 65u and 65d are bent portions 63u, 63u and 63d. 63d, it is still difficult to insert a foreign object such as an IC clip or a wire. This eliminates the need for strict gaps to prevent fraud, and increases the degree of design freedom.

  Since the substrate storage case 46 is made of a transparent material, if a foreign object such as an IC clip or a wire is inserted as a fraudulent act, the discovery of an external damage such as a scratch on the substrate storage case 46 at that time is detected outside the substrate storage case 46. Easy to see even from

Therefore, when it is determined that an illegal act has been made, it is possible to take a countermeasure immediately.
Further, since the H-type heat radiating member 54 and the main board 44 are separated, there is no possibility that concentrated stress due to the assembly of the H-type heat radiating member 54 to the main board 44 will occur. Moreover, since both members are separated, each member is reduced in weight, so that assembly is easy.

(2) Mount 58
The substrate storage case lower portion 50 of the substrate storage case 46 is provided with a plurality of mounts 58 as protrusions protruding toward the case internal space S of the substrate storage case 46, and the main substrate 44 is provided on these mounts 58. It is placed in a contact state. Therefore, even if the temperature inside the case increases due to heat generated by components (not shown) arranged on the main board 44, the heat inside the case is released to the outside of the case via the main board 44 and the gantry 58. . For this reason, the temperature in the substrate storage case 46 can be lowered without forming gaps or heat dissipation holes in the substrate storage case 46.

  The base 58 may be formed by injection molding the substrate housing case lower part 50 including the base 58 or an insert embedded by insert molding so as to be the base 58. The degree increases.

When the pedestal 58 is formed by insert molding, it is desirable to apply a metal material. For example, it is preferable to use aluminum having a relatively high thermal conductivity.
Further, since the gantry 58 is a hollow body whose one end faces the outside air, the heat transfer coefficient can be further increased.

Furthermore, since the area in contact with the outside air is increased by forming notches and kerfs in the inner surface of the hollow portion of the pedestal 58, the heat transfer rate can be further increased.
The notches and kerfs may be formed on the outer surface of the pedestal 58, and the notches and kerfs may be formed on both the hollow portion and the outer surface of the pedestal 58. Furthermore, the heat transfer rate is further increased.

In addition, the amount of heat released to the outside of the substrate storage case 46 is increased by setting the size of the gantry 58 and the size of the hollow portion, step, cut groove, and the like associated therewith according to the size of the substrate storage case 46. Is possible. Therefore, depending on the amount of heat generated from the heat-generating component mounted on the main board 44, the H-type heat radiation member 54 can be eliminated. In this case, since there is no gap in the substrate storage case 46, it is extremely effective in terms of security and can further prevent fraud. Further, only the pedestal 58 is used as the heat radiating portion, but the pedestal 58 protrudes into the case internal space S of the substrate storage case 46 but does not protrude outside the substrate storage case 46. Therefore, the pachinko gaming machine of the substrate storage case 46 When attaching to I, the heat radiating part does not interfere with the work.
