Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control device in which a control circuit board of a game machine such as a pachinko game machine or a slot machine is housed in a case.

[0002]

2. Description of the Related Art Generally, a gaming machine such as a pachinko gaming machine or a slot machine has a jackpot determination, a winning determination, a prize ball (a gaming ball paid out according to a gaming ball entering a winning opening. In the case of a slot machine, A coin is used instead of a game ball, but for convenience of explanation, it is called "prize ball"), CR
A control device having a control board for generating a sound or emitting light according to a game state such as a payout or a jackpot in a (Card Reader) machine is provided on the back side. In general, a circuit provided on this control board includes a unique control circuit that performs a jackpot determination, a winning determination, or a control specific to each gaming machine such as sound and light emission, and a control common to a plurality of types of gaming machines such as payout. And a general-purpose control circuit. Therefore, in order to increase versatility, the control board is usually designed by dividing into a main board having a unique control circuit and another board such as a dispensing board having a general control circuit. It is.

Since the main board and the payout board are related to the payout of the prize ball, they are attached to the back surface of the gaming machine in a sealed state in a case where the trace of opening can be easily confirmed. This is to prevent unauthorized alteration of the control circuit in a store or the like. The case is made of a transparent material capable of recognizing the contents from the outside. For example, a pair of upper case and lower case located on both sides of the substrate and a joint portion thereof are provided. And some sealing structure.

[0004]

By the way, when manufacturing and selling a game machine, in order to obtain a certification that its function is within an appropriate range specified by law, Japan Security Electronics Communication Association. It is necessary to take a "type test". The most important thing in this type test is a part related to payout of award balls, that is, a game control function such as a jackpot determination or a determination of the number of award balls to be paid out of the unique control circuit (main board). It has a general-purpose control circuit (payout board) for controlling payout of award balls, and a strict inspection. On the other hand, the portion of the unique control circuit that controls sound, light emission, and the like is not related to the payout of prize balls, and in recent years, the content of the type test tends to be simplified.
Document screening was sufficient. Therefore, if a part for controlling sound, light emission, and the like is separated from the main board having the game control function and configured on another board, the inspection can be simplified.

[0005] However, when the main board and the control board for audio and the like are divided as described above for the purpose of simplifying the inspection, they have to be accommodated in separate cases. Even when housed in the sealable case as described above, it is difficult to configure the sealing structure so as to completely prevent unsealing without leaving any trace. For this reason, if the divided control boards for audio and the like are accommodated in one case at the same time as the main board and connected inside the case, it is easy to illegally connect them to each other, and the minimum It is not impossible to connect and mount a substrate of a size to the main substrate. In addition, since the wiring state inside the case is complicated, the staff at the game hall cannot easily determine from the outside of the case whether or not the initial proper state is maintained.
Therefore, even if the control board such as a sound is separated from the main board, if they are housed in one case, it is equivalent to being provided integrally with the main board. In order to achieve this, it was necessary to house the main board in a case separate from that of the main board so as to suppress unauthorized connections that are difficult to detect, and to connect only outside the main board. As a result, when separating the control board for audio etc. from the main board,
Compared with the related art in which the unique control circuit is provided on one substrate, the number of control devices attached to the back surface of the gaming machine increases, and there is a problem that a large installation area is required as a whole.

[0006] The problem that unauthorized connection becomes easier when a plurality of boards are accommodated in one case as described above is not limited to the case where a control board such as a sound board is separated from a main board. This can occur in the same manner with other control boards provided in the system. For example, if the main board and another board such as a dispensing board are simultaneously accommodated, or the dispensing board and the control board for the sound or the like are simultaneously accommodated in one case, the number of control devices is reduced. Installation area can be reduced. However, since the payout board also has a control circuit related to the payout of the prize ball as described above, when accommodating a plurality of boards including such a main board and the payout board in one case, In any combination, the problem of illegal connection inside the case as described above occurs. That is, the conventional sealing structure of the control device case as described above connects a control board provided with a control circuit having a function related to payout of a prize ball to another board accommodated at the same time, and performs the function. The effect of suppressing improper modification such as alteration of the control board was not sufficient, so it was difficult to reduce the number of control devices and reduce the required installation area by accommodating a plurality of control boards in one case at the same time. Had become.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a gaming machine capable of reducing an installation area while suppressing unauthorized modification of a control board related to payout of award balls. It is to provide a control device.

[0008]

In order to achieve the above object, the gist of the control device for a gaming machine of the present invention is as follows.
(a) a first substrate provided with a first control circuit having a function related to payout of award balls in a gaming machine; and (b) a second substrate.
A second substrate provided with a control circuit of (c);
(D) exposing the first and second substrates to respective electrode terminals, the electrode terminals being provided at their edges to electrically connect the first and second substrates to each other. A case having a housing position for simultaneously housing the inside in a state of being made, and a partition having a partition partitioning each of the housing positions so that their electrical connection in the interior is disabled; and (e) the first And a sealing device for sealing the case so that a trace of the substrate located inside the case is easily visible when the part is opened.

[0009]

In this way, the first substrate and the second substrate are simultaneously accommodated in one case, and they are mutually connected by the electrode terminals at the edge exposed outside the case. In the case provided with the sealing device, a partition partitioning the first substrate and the second substrate in a state where the first substrate and the second substrate cannot be electrically connected to each other so as to be separated from each other. Provided. Therefore, since the first substrate and the second substrate are simultaneously accommodated in one case, the installation area of the control device can be reduced as compared with the case where they are accommodated in separate cases. And the first
The electrical connection between the substrate and the second substrate can be made only outside the case, so that even if they are incorrectly connected, it is easy to find them, and it is difficult to find them easily. There is also an effect of psychologically suppressing the processing. Therefore, it is possible to reduce the installation area of the control device while suppressing the unauthorized modification of the first substrate related to the payout of the prize ball, such as the jackpot determination, the winning determination, the determination of the payout number of the prize ball, and the payout. .

[0010]

Preferably, (d-2) the case comprises a lower case portion located on the back side of the substrate and an upper case portion located on the front side of the substrate. And
(f) The partition has a fitting structure in all abutting portions formed between at least one of the upper case portion and the lower case portion. If you do this,
The contact surface between at least one of the upper case portion and the lower case portion constituting the case and the partition wall is bent by providing a fitting structure. Therefore, if an incorrect wiring that passes through the mutual contact portion is provided in the case, it will be difficult to close the case because it disturbs the fitting structure, or the wiring will be bent at the fitting portion. Disconnects easily from being done. Therefore,
Compared to the case where the contact part between the partition and the upper case part and the lower case part is configured as a flat butted surface,
It becomes more difficult to provide incorrect wiring.

[0011] Preferably, the second control circuit provided on the second substrate does not have a function related to payout of award balls. According to this configuration, the control device for the gaming machine includes the first substrate provided with the first control circuit having the function related to the payout of the prize ball, and the second substrate having no such function. The substrate and the substrate are simultaneously accommodated in one case provided with a sealing device in a state where the substrate is partitioned into partitions so that electrical connection inside the substrate is not possible. for that reason,
Since electrical connection between the first substrate and the second substrate is impossible in the case, they are equivalent to being housed in substantially independent cases, respectively. Therefore, even if the first substrate requiring rigorous inspection is housed in the same case as that of the first substrate, this does not affect the necessity of rigorous testing on the second substrate at all. A rigorous test on the second substrate having no function related to the above is not required, and the type test can be simplified. In particular, even when the second substrate is a substrate divided from the first substrate (for example, a control substrate for audio or the like divided from the main substrate), it is the same as when they are integrally provided. Since the first substrate can be accommodated in one case simultaneously with the first substrate, there is also an advantage that an increase in the installation area of the control device due to the division of the substrate is suppressed.

Therefore, in an assembled state as shown in FIG.
In addition, a part of the distal end portion of the lower partition plate 142 is overlapped to form a so-called “jakuri” structure which is equivalent to fitting of the contact surfaces 158 and 160. Therefore, in the case 84, these upper partition plates 15
4 and the lower partition plate 142 are less likely to form a gap, so that it is more difficult to provide electrical wiring through the gap. That is, the upper partition plate 154 and the lower partition plate 14
The height dimension of each of the two is set to a height at which some of them overlap one another.

Further, as described above, the contact surfaces 158, 160
Is bent, it is difficult to completely cover the upper cover 122 on the lower cover 124 because the wires existing there obstruct the wiring even if wires are forced through them. Therefore, the fact that the improper treatment has been performed can be identified at a glance because the case 84 is not completely assembled. Even if the case 84 can be completely assembled and sealed, even if the wiring is easily bent and disconnected at the step, the illegal processing is likely to become meaningless. For this reason, according to the structure of the present embodiment, in addition to the physical fraud suppression effect that the two housing portions 156a and 156b are completely partitioned, there is also a psychological fraud suppression effect. In addition, as a result of the fraud being substantially prevented, the accommodation portions 156a and 156b of the main board 82 and the sub-board 126 are substantially independent. As a result, according to the case 84 of the present embodiment, the inspection of the type test of the sub-board 126 is simplified despite the fact that the main board 82 and the sub-board 126 are simultaneously accommodated. The "fitting structure" in the claims includes a "jakuri" structure as in this embodiment as long as the contact surface can be bent.

Returning to FIG. 6, bosses 162 are provided on the inner surface of the lower cover 124 at positions corresponding to the four corners of each of the storage portions 156a and 156b. Substrates 82 and 1
The screw 26 is fixed to the lower cover 124 as shown in FIG. 7A by screwing the screws 148 into the plurality of bosses 162.

FIGS. 8A to 8C are views for explaining the details of the sealing structure formed by the screw tightening portion 136 and the boss 144 provided in the case 84. FIG. In the figure, (a)
Shows a state before the upper cover 122 is attached to the lower cover 124, (b) shows a state where the upper cover 122 is fixed to the lower cover 124 by tightening the screws 146, and (c) shows a cut piece. The upper cover 122 which has been fixed by cutting the
4 shows a state separated from FIG. In FIG. 8A,
The screw fastening portion 136 has a bottomed hole 164 having a peripheral wall formed by a wall surface extending toward the lower cover 124 on the inner peripheral side of the cut piece 134, and a tapered bottom formed at the bottom of the bottomed hole 164. A through hole 166 is provided, and the tip of the screw 146 is further screwed into the through hole 166 in a state where the screw 146 is entirely in the bottomed hole 164.
The screw holding portion having a function of holding the screw 146 is formed by the bottomed hole 164 and the through hole 166 of the screw tightening portion 136. On the other hand, the boss 144 has a boss hole 168 smaller than the diameter of the completely threaded portion of the screw 146 on the inner peripheral side.
Are provided coaxially with the above-mentioned through hole 166.

FIG. 9 is a view for explaining the screw 146 and the screw holding section in detail. The figure shows a longitudinal section of the screw holding portion, that is, the bottomed hole 164 and the through hole 166. The screw 146 is connected to the head 190 and the shaft 19.
2, and the screw thread 194 is provided only in a range of approximately half the length of the tip of the shaft portion 192. The head 190 is a flat head screwdriver 222.
(See FIG. 10 to be described later.) A pair of tips are provided so as to stand almost vertically from the top surface 230 with which the abutment comes into contact, form an incomplete groove 224 therein, and allow the tip side surface 226 of the driver 222 to abut. Abutment surfaces 196 and 196, and a pair of slopes 198 formed gently from the upper surface 230 thereof.
198 are provided point-symmetrically with respect to the axis. Therefore, in the screwing direction indicated by the arrow T in the figure, the screw 146 can be turned because the contact surface 196 engages with the tip of the driver 222, but in the opposite loosening direction, the driver tip is inclined 198. It is not possible to turn screw 146 to slip on.

FIGS. 10A to 10D schematically show how the screw 146 is to be rotated in the screwing direction or the loosening direction when the head 190 is viewed from directly above. It is. (a) shows the planar shape of the head 190, and (b) shows the groove 22 formed between the contact surfaces 196 and 196.
4 shows a state where the tip of the flathead screwdriver 222 is fitted. As shown in FIG.
When the driver 222 is rotated in the screwing direction T as shown in (c) in a state where 2 is fitted in the groove 224, the tip side surface 226 is caused to act in the direction of pressing the contact surface 196. Therefore, the contact state is maintained and the torque is transmitted to the screw 146, and the boss 144
Will be tightened. Conversely, when the driver 222 is rotated in the loosening direction R as shown in FIG.
Since the contact surface 196 is not provided at the position where the other side surface 228 is to be pressed, the distal end surface of the driver 222 slides on the upper surface 230 and rides on the slope 198. Therefore, the contact state between the contact surface 196 and the side surface 226 is not maintained, and the tip of the driver 222 is disengaged from the groove 224, so that torque is not transmitted to the screw 146. Therefore, the screw 146 cannot be loosened. The screw 146 has a one-way structure by including such a head 190.

Returning to FIG. 8, in the state shown in FIG. 8B, the upper cover 122 and the lower cover 124 are fixed by screwing the screws 146 into the boss holes 168. The screw 146 is connected to the shaft 192 as described above.
Since the screw thread 194 is provided only at the tip of
Even if the screw 146 is excessively screwed in to fix the boss hole 168 in such a fixed state, the inner wall surface of the boss hole 168 is not cut in the portion where the screw thread 194 is not provided. . Therefore, even in such a case, the screw 146 is securely fixed to the boss 144 based on the engagement between the screw thread 194 and the inner wall surface above the boss hole 168. The range in which the thread 194 of the screw 146 is provided is such that the portion where the thread 194 is not provided in the most threaded state enters the boss hole 168 with a sufficient length. And boss 14
Boss 1 from the bottom surface of bottomed hole 164 in the contact state with boss 1.
The distance to the top of 44 is determined to be shorter than the length of the portion where the thread 194 is not provided.

As described above, since the upper cover 122 and the lower cover 124 are fixed by the screws 146 that can be rotated only in one direction, it is almost impossible to loosen the screws 146 and separate them. Therefore, when it becomes necessary to separate them from each other for the purpose of inspection or the like, the following processing is performed. As described above, the portion provided with the bottomed hole 164 and the through hole 166 constituting the screw holding portion is connected to the upper cover 122 with only the thin cut piece 134. Therefore, when this connecting portion is cut using a nipper or the like, the connected state is canceled,
The upper cover 122 can be removed while the screw 146 and the screw holding portion are fixed to the lower cover 124. FIG. 8 (c) shows a state in which the components are separated in this manner. Therefore, the case 84 corresponds to the upper case 12
2 is accompanied by such an irreversible change in the screw tightening portion 136, so that it can be easily identified whether or not the upper case 122 has been removed. It can be prevented.

When the upper cover 122 is removed for the purpose of inspection or the like, it is necessary to attach it again to the lower cover 124 and seal it in order to prevent subsequent fraud.
The reason why the screw fastening portions 136 are provided at a plurality of locations as shown in FIG. 4 and the like is to enable sealing at this time. In other words, only one screw tightening portion 136 provided at each end is used in one sealing operation, and at the same time, the screw 146 fastened to the boss 144 is used.
Is always only two. Therefore, after one seal is destroyed as described above, the screw 146 is tightened by the screw tightening portion 136 provided in another place, and the seal is similarly performed by the screw 146 which cannot be removed. Therefore, the seal can be performed four times including the first seal.

As described above, according to the present embodiment,
The main board 82 and the sub-board 126 are simultaneously in one case 84.
And are connected to each other by electrode terminals 128 and 130 exposed to the outside of the case 84, and are provided with a screw portion 136 and a boss 144 functioning as a sealing device. The lower partition plate 142 and the upper partition plate 154 divide the accommodating portions 156a and 156b from each other so that the main board 82 and the sub-board 126 cannot be electrically connected inside.
Is provided. Therefore, since the main board 82 and the sub-board 126 are accommodated in one case 84 at the same time, an increase in installation area caused by dividing the board having the unique control circuit into these two boards is suppressed. Further, since electrical connection between the main board 82 and the sub-board 126 is not possible in the case 84, they are equivalent to being housed in substantially independent cases. Therefore, the main substrate 8 requiring strict inspection is required.
2 is stored in the same case 84 as the
No rigorous testing of 6 is required. In addition, since the electrical connection between the main board 82 and the sub-board 126 can be made only outside the case 84, it is easy to find them even if they are connected illegally, and it is not possible to find them easily. There is also an effect that psychologically suppresses the electrical connection processing. Therefore, the unique control circuit is provided on one board, or it is separated from the main board 82 and the sub-board 126, and compared with any conventional control device housed in one case, Without increasing the area, it is possible to obtain the control device 120 that can further suppress the unauthorized modification of the main substrate 82 related to the payout of the prize ball and can further simplify the type test.

Moreover, according to the present embodiment, the lower partition plate 1
Abutment surfaces 158, 1 of the upper partition plate 154 and the upper partition plate 154;
Since the 60 is bent by providing an interlocking structure (ie, what can be said to be a substantially mating structure), if an incorrect wiring passing through the mutual contact portion is provided in the case 84, it is It is difficult to close the case 84 because the fitting structure is disturbed, or the wiring is easily bent because the wiring is bent at the fitting portion. Therefore, it becomes more difficult to provide incorrect wiring as compared with the case where the contact portions between the partition and the upper case 122 and the lower case 124 are formed as flat butted surfaces.

In the present embodiment, the electrical connection between the main board 82 and the sub-board 126 can be made only by connecting the electrode terminals 128 and 130 located outside the case 84 with the connector 138. Case 84
It is possible to cut off these electrical connections without opening. Therefore, type testing, product inspection in the factory,
Even when it is necessary to separately inspect the main board 82 and the sub-board 126 for the inspection of the presence or absence of improper processing in the store, they can be electrically separated simply by removing the connector 138. There are advantages too.

Next, another embodiment of the present invention will be described. In the following embodiments, portions common to the above-described embodiments will be denoted by the same reference numerals and description thereof will be omitted.

FIGS. 11A to 11C are diagrams for explaining other examples of the configuration of the partition plate. In the structure shown in (a), a partition plate 200 which is entirely integrated with the lower cover 124 is provided. On the inner surface of the upper cover 122, a concave groove 202 extending along the longitudinal direction of the partition plate 200 perpendicular to the paper surface.
The tip 204 of the partition plate 200 is fitted in the concave groove 202. Therefore, in this embodiment, a fitting structure is formed between upper cover 122 and partition plate 200. Even in this case, the two receiving portions 156a and 156b are completely separated from each other, and the contact surface between the upper cover 122 and the partition plate 200 is bent. As in the embodiment, the effect of suppressing fraud and simplifying the inspection can be obtained.
Note that, unlike the structure shown in FIG. 7, in this embodiment, the leading end 204 of the partition plate 200 is flat, but the leading end 204 is fitted into the upper cover 122 to form a U-shape including the side surface. Since the range formed substantially functions as a contact surface, it is not necessary to dare the tip 204 into a stepped shape.

Further, in the structure shown in FIG. 11B, a partition plate 206 which is entirely integral with the upper cover 122 is provided, contrary to the case of FIG. The inner surface of the lower cover 124 is provided with a V-groove 208 extending along the longitudinal direction of the partition plate 206 perpendicular to the paper surface, and the tapered tip 210 of the partition plate 206 is fitted into the V-groove 208. Have been. Therefore, in this embodiment, a fitting structure is formed between the lower cover 124 and the partition plate 206. Even in this case, the two storage portions 156a,
156b is completely separated, and the contact surface between the lower cover 124 and the partition plate 206 is bent.
As in the first and second embodiments, the effect of suppressing fraud and simplifying the inspection can be obtained. That is, the component part functioning as a partition partitioning the housing portion 156 may be provided separately in the upper cover 122 and the lower cover 124 as in the embodiment shown in FIG.
As in the embodiment shown in (a) and (b), only one may be entirely provided. The shape of the contact portion between the partition and the upper cover 122 or the lower cover 124 may be any shape as long as a contact surface bent in a direction from the main board housing portion 156a to the sub-board housing portion 156b is formed. It is possible to take various shapes as shown in FIG.

In the structure shown in FIG. 11 (c), a partition plate 212 formed separately from the upper cover 122 and the lower cover 124 is provided. Recessed grooves 214 and 216 are provided on the inner surfaces of the upper cover 122 and the lower cover 124, respectively, and the upper end 218 and the lower end 220 of the partition plate 212
4, 216. Therefore, in this embodiment, a fitting structure is formed between both the upper cover 122 and the lower cover 124 and the partition plate 212. Of course, even in this case, the storage section 156a,
156b are separated from each other,
The fact that the contact surface between the base 12 and the upper cover 122 and the lower cover 124 is bent is the same as in the above-described embodiments.
Similar fraud suppression effects and inspection simplification effects can be obtained.

While the embodiment of the present invention has been described in detail with reference to the drawings, the present invention can be implemented in other embodiments.

For example, in the embodiment, the case where the present invention is applied to the control device 120 of the pachinko machine 10 has been described. However, the main board 82 has a function of determining a jackpot and determining the number of payouts of prize balls. A board provided with a control circuit, that is, a first board provided with a control circuit related to the payout of award balls, and a second board other than the first board provided with a control circuit which is not involved in the determination and therefore the payout is provided. The present invention can be similarly applied to those for other gaming machines such as slot machines as long as a plurality of boards including the sub board 126 are accommodated in the case 82 at the same time.

In the embodiment, the sub-board 126 accommodated in the case 84 at the same time as the main board 82 controls light emission and sound effect generation.
The present invention is similarly applied to the case where the payout board 80 for paying out the prize balls is simultaneously accommodated in the case. Further, the payout board 80 for paying out the prize ball to the prize ball payout device 74 also has the “function related to the payout of the prize ball”, so that this and the above-described sub-board 126 are simultaneously accommodated in the case. In such cases, the present invention is similarly applied. That is, even if the second control circuit provided on the second substrate does not have a function related to the payout of the prize ball, the second control circuit related to the payout of the prize ball similarly to the first control circuit. It may have the function of performing. Therefore,
Not only when the second substrate is provided with a control circuit having no function related to the payout of the prize ball, but also when the first substrate and the second substrate are both provided with the function related to the payout of the prize ball. A substrate provided with a control circuit having
The present invention applies.

Further, in the embodiment, the case where the fitting structure in which the contact surfaces 158, 160 of the partition plates 142, 154, etc. functioning as the partition walls are bent is described. The structure does not necessarily have to be provided. For example, the contact surfaces 158, 160 and the like may be configured to be simply butted as flat surfaces. Even in this case, it is possible to determine at a glance that it is unnatural that some wiring passes through the portion where the partition wall is provided through the transparent case, and it is easy to confirm that the illegal processing has been performed, It is possible to sufficiently obtain the fraud suppression effect and the effect of simplifying the inspection.

In the embodiment, the case 84 is composed of the upper cover 122 and the lower cover 124. However, the case 84 may be composed of three or more components.

In the embodiment, two substrates 8 are used.
The case where the present invention is applied to the control device 120 in which the control units 2 and 126 are simultaneously accommodated in the case 84 has been described.
If at least one of the boards is required to prevent illegal wiring processing and simultaneously accommodates at least one other board that needs to be electrically connected to the board, The present invention is similarly applied to a control device in which three or more boards including another board which is not connected to a board requiring fraud prevention are simultaneously accommodated in a case.

Further, in the embodiment, the sealing device is constituted by the screw fastening portion 136 and the boss 144. However, a trace that separates the upper cover 122 and the lower cover 124 becomes clear, and sealing can be performed again. If
Various other sealing structures such as welding can be employed.

Also, in the embodiment shown in FIGS. 1 to 10, the heights of the lower partition plate 142 and the upper partition plate 154 are determined so that a part of the top ends thereof overlaps. These are set to a height at which they are almost completely overlapped with each other, and their positions are slightly shifted in the thickness direction, so that the housing portions 156a and 156b can be mutually connected by the double partition plates which are almost in close contact with each other. You may comprise so that it may be separated.

Although not specifically exemplified, the present invention can be embodied in variously modified forms without departing from the gist thereof.
