Description

  The present invention relates to a gaming machine provided with a board case that houses a control board.

  A gaming machine typified by a pachinko machine includes various control boards that execute control related to game contents. Since these control boards are equipped with ROMs that store programs related to game content, it is not possible to replace them with unauthorized control boards that are equipped with ROMs that store illegal programs. One of the important issues. Here, in the gaming machine, the control board is housed in a board case composed of a base member and a cover member (see, for example, Patent Document 1).

  In the substrate case of Patent Document 1, after the base member and the cover member are assembled, the caulking portions formed on the base member and the cover member are fixed so as not to be separated. In the substrate case having such a configuration, since it cannot be opened unless the crimped portion is broken, it is possible to recognize that the act of opening the substrate case is performed by the trace of the crimped portion being broken.

JP2013-121441A

  However, in recent years, fraudulent acts by fraudsters have become more sophisticated, and there are cases where fraudulent acts are carried out without clearly leaving traces of fraudulent acts such as the above-mentioned fracture marks of the caulking portion in the substrate case. For this reason, there is a demand not only for countermeasures against fraud that leave traces of fraud, such as caulking, but also for making the fraud itself difficult.

  In view of the above problems inherent in the conventional technology, the present invention has been proposed to suitably solve these problems, and a gaming machine having a board case in which it is difficult to insert an unauthorized device into the case. The purpose is to provide.

In order to solve the above-mentioned problem and achieve the intended purpose, the invention according to claim 1 of the present invention provides:
A substrate case (25) in which a control board (22) mounted with a control electronic component (23a) is stored in a storage space (25a) defined between the base member (30) and the cover member (50). In a gaming machine equipped with
A base-side groove (39) formed to extend along an edge of the base member (30) and open to the cover member (50) side;
The cover member (50) is formed on the side of the base member (30) and is open on the side of the base member (30). A cover side groove (59) extending in parallel with the base side groove (39);
It is formed on the base member (30) and extends toward the cover member (50), extends along the groove (39, 59), and the extended end faces the cover-side groove (59). Base side regulation wall (36,37),
It is formed on the cover member (50) and extends toward the base member (30) and extends along the groove (39, 59), and the extended end faces the base-side groove (39). Cover side regulating wall (52, 53),
In the state where the cover side regulating wall (52, 53) faces the base side groove (39) and the base side regulating wall (36, 37) faces the cover side groove (59), the base member ( 30) and the cover member (50), the base-side groove portion (39) and the cover-side groove portion (59) are extended to a position where the storage space (25a) is opened and a position where the storage space (25a) is closed. The gap (S) formed by the groove portions (39, 59) and the restriction wall portions (36, 37, 52, 53) is configured so as to be relatively slidable along the direction. The gist of the present invention is that it has a meandering shape that folds back and forth in a direction intersecting the inner and outer directions of 25a).
In this configuration, the base-side groove portion, the cover-side restriction wall portion with the protruding end facing the base-side groove portion, the cover-side groove portion, and the base-side restriction wall portion with the protruding end portion facing the cover-side groove portion are formed. The substrate case is formed in a meandering manner in which a plurality of gaps of the substrate case are bent back and forth in the direction intersecting the inside and outside directions of the storage space. Therefore, even if a fraudulent person tries to insert a fraudulent instrument through the gap in the board case to reach the front or back surface of the control board, the movement direction of the instrument is changed several times in the gap before the inserted instrument reaches the storage space. It must be changed, making it difficult to bring the instrument to the front or back surface of the control board. Similarly, when an unauthorized instrument is inserted, the traveling direction of the instrument must be changed a plurality of times in the gap to the storage space in order to collect the inserted instrument, and the unauthorized instrument can be easily recovered. I can't. In this way, not only does it make it difficult for an unauthorized device to enter, but it also takes time to complete the purpose of the illegal act, leading to abandonment of the illegal act. That is, it is possible to prevent an illegal act of modifying the control board from the outside of the board case.

The invention according to claim 2
The gist is that the outer peripheral end surface (24) of the control board (22) forms part of the inner wall surface of the base side groove (39) or the cover side groove (59).
In this configuration, a part of the inner wall surface of the base side groove part or the cover side groove part is formed by the outer peripheral end face of the control board, and the outer peripheral end face of the control board faces the meandering gap (intrusion path of unauthorized equipment) of the board case. By doing so, it becomes easy to leave a trace due to an unauthorized device inserted into the gap at the end of the control board. In other words, by leaving a trace on the control board itself that is intensively observed when checking for the presence or absence of abnormality, it is possible to contribute to early detection of implementation of fraud. In addition, by making it difficult for an unauthorized device to enter the board surface of the control board, it is possible to prevent the purpose of fraudulent activity from being achieved.

In the invention according to claim 3,
The base side regulation wall (36, 37) forms the inner wall surface of the base side groove (39), and the cover side regulation wall (52, 53) forms the inner wall surface of the cover side groove (59). The gist is to form.
In this configuration, the base-side restriction wall portion forms the inner wall surface of the base-side groove portion in the base member, and the cover-side restriction wall portion forms the inner wall surface of the cover-side groove portion in the cover member. The width of the substrate case in the direction intersecting the extending direction of each groove portion and each regulating wall portion while configuring the substrate case so as to form a meandering shape in which the gap between them is bent in multiple directions in the direction intersecting the inside and outside directions of the storage space Can be made small.

In the invention according to claim 4,
A first engagement portion (38a, 38b) is formed on the inner wall surface forming either the base side groove portion (39) or the cover side groove portion (59),
The base side regulating wall portion (36, 37) or the cover side regulating wall portion corresponding to the base side groove portion (39) or the cover side groove portion (59) in which the first engaging portion (38a, 38b) is formed. (52, 53) is formed with a second engagement portion (58a, 58b) engageable with the first engagement portion (38a, 38b),
When the base member (30) and the cover member (50) are slid relative to the closed position from the open position, the first and second engaging portions (38a, 38b, 58a, 58b) The gist is that it is configured to suppress the slide displacement from the closed position to the open position by pressing.
In this configuration, when the base member and the cover member are slid to the closed position, the first and second engaging portions that are in pressure contact and restrict the slide displacement toward the open position of the base member and the cover member are provided. By forming the base side groove part and the cover side regulating wall part, or the inner wall surface of the cover side groove part and the base side regulating wall part so as to be engageable with each other, there is a margin in the groove width of the base side groove part and the cover side groove part. Even if it is provided, the relative displacement of the base member and the cover member in the groove width direction can be restricted by the press-contact between the engaging portions, so that the ease of sliding displacement of the base member and the cover member can be ensured. Further, since the first and second engaging portions are in pressure contact with each other, it is difficult to form a front opening for inserting an unauthorized device by relatively displacing the base member and the cover member in the groove width direction. Can prevent unauthorized equipment from entering.

The invention according to claim 5
One of the base member (30) and the cover member (50) (30) has a side closer to the storage space (25a) than an end portion in the sliding direction of the opposing wall portion (31) facing the control board (22). Further, a side regulating portion (35) protruding toward the other member (50) side of the base member (30) and the cover member (50) is formed,
The other (50) of the base member (30) and the cover member (50) is an outer wall that defines the storage space (25a) on the opposing wall portion (31) where the side regulating portion (35) is formed. The end surface of the portion (55) faces, the inner surface of the outer wall portion on the storage space (25a) side faces the side restricting portion (35), and the outer wall portion (55) and the side restricting portion (35) are stowed. The gist is that the space (25a) is configured to overlap in the inner and outer directions.
In this configuration, the opposite wall portion constituting one side of the base member and the cover member faces the end surface of the outer wall portion on the other side, and the outer wall portion is formed on one side of the base member and the cover member. By constructing the control unit so that it faces the inside and outside of the storage space, even if an unauthorized person tries to reach the front or back surface of the control board by inserting a fraudulent instrument through the gap in the board case, Since the traveling direction must be changed inside the substrate case, and it becomes difficult to bring the instrument to the front or back surface of the control board, it is possible to prevent the purpose of fraud from being achieved.

That is, when it is necessary to open the substrate case 25 after the base member 30 and the cover member 50 are once connected and fixed, the breaking connecting portions 96 and 96 are broken so that the cover side connecting portion 95 is connected to the cover member 50. The substrate case 25 can be opened by being separated from the substrate case, and the opening trace of the substrate case 25 remains.

  Here, the separation dimension of the upper edge portion 93 a and the lower edge portion 93 b in the surrounding wall 93 is formed to be slightly smaller than the upper and lower width dimensions of the connection fitting portion 97. That is, when the base member 30 and the cover member 50 are relatively slid from the open position to the closed position and the connection fitting portion 97 is fitted inside the surrounding wall 93, the connection fitting portion 97 is The upper and lower edges 93a and 93b of the wall 93 are pressed against each other, and are configured to be able to alleviate the impact when the substrate case 25 is closed. That is, in the substrate case 25 of the embodiment, when the substrate case 25 is slid and displaced from the open position to the closed position, the engagement protrusions 57a and 57b of the upper and lower cover-side outer walls 52 and 53 and the upper and lower The outer wall right end portions 32a and 33a of the outer wall portions 32 and 33 are in pressure contact with each other, and the base side connection portion 91 and the cover side connection portion 95 are in pressure contact with each other to provide resistance to sliding movement.

  As shown in FIGS. 3, 5, and 6, the substrate case 25 is provided with a preliminary connection fixing portion 100 that connects and fixes the base member 30 and the cover member 50 to the open position so that they cannot be displaced. Specifically, the base member 30 is formed with a base side preliminary connecting portion 101 that constitutes a preliminary connecting and fixing portion 100 below the base side connecting portion 91, and the cover member 50 has the cover side A cover side preliminary connecting portion 105 constituting the preliminary connecting and fixing portion 100 is provided at a position below the connecting portion 95. The basic configuration of the base side preliminary connecting portion 101 is the same as that of the base side connecting portion 91, and the basic configuration of the cover side preliminary connecting portion 105 is the same as that of the cover side connecting portion 95. Detailed description will be omitted. The preliminary connection fixing portion 100 is used when the base member 30 and the cover member 50 are temporarily fixed after the connection fixing portion 90 is broken and the substrate case 25 is opened.

  In addition, a seal seal sticking portion 110 extending outward (right side) is provided at an upper position of the cover side right outer wall portion 54 in the base member 30 and an upper position of the cover side right outer wall portion 54 in the cover member 50. 111 is formed, and when the base member 30 and the cover member 50 are displaced to the closed position, a seal seal (not shown) can be pasted so as to straddle the joint of the seal seal pasting portions 110, 111. ing. Further, the sealing sticker attached to the sealing sticker attaching portions 110 and 111 is covered with a seal cover 113 (see FIG. 1) that can be seen through from the outside.

(Operation of Example)
Next, the operation of the pachinko machine 10 according to the above-described embodiment will be described.

  The substrate case 25 of the main control device 20 has a base-side groove 39, 39 formed between the upper and lower base-side outer walls 32, 33 and the corresponding upper and lower inner walls 36, 37 in the base member 30. The upper and lower cover-side outer wall portions 52 and 53 of the cover member 50 are inserted from the front side, and the cover-side groove portions 59 and 59 formed so as to extend in parallel with the base-side groove portions 39 and 39 with respect to the cover member 50. The upper and lower inner wall portions 36 and 37 (specifically, the first upper and lower inner wall portions 36a and 37a) are inserted from the rear to extend the base side groove portions 39 and 39 and the cover side groove portions 59 and 59. The base member 30 and the cover member 50 are configured to slide relative to each other in the direction. That is, the base-side upper outer wall portion 32, the upper inner wall portion 36 (first upper inner wall portion 36a) and the cover-side upper outer wall portion 52 of the base member 30 overlap in the inner and outer directions (vertical direction) of the storage space 25a, and the base member The base-side lower outer wall portion 33, the lower inner wall portion 37 (first lower inner wall portion 37a), and the cover-side lower outer wall portion 53 in FIG. 30 are configured to overlap in the inner / outer direction (vertical direction) of the storage space 25a. The gap S defined by 25 has a meandering shape that refracts a plurality of times in a direction (front-rear direction) intersecting the inner and outer directions of the storage space 25a.

  For this reason, a gap generated when the base member 30 and the cover member 50 are relatively slid to open and close the substrate case 25 (in the embodiment, the upper and lower cover sides corresponding to the upper and lower base side outer wall portions 32 and 33). Even if an unauthorized instrument inserted through the gap between the outer walls 52 and 53 reaches the mounting surface 22a or the solder surface 22b of the main control board 22, the improper instrument is inserted in the gap S from the case to the storage space 25a. Since the advancing direction has to be changed a plurality of times, it becomes difficult to bring an unauthorized instrument to the mounting surface 22a and the solder surface 22b of the main control board 22, and thus illegal acts using the gap S are effectively prevented. It becomes possible to do. Further, in order to prevent unauthorized equipment from remaining as a trace of illegal activities even if the unauthorized equipment can reach the mounting surface 22a and the solder surface 22b of the main control board 22, in order to collect the unauthorized equipment. In addition, the traveling direction of the instrument must be changed a plurality of times in the gap S reaching the storage space 25a, and the unauthorized instrument cannot be easily collected. As described above, in the substrate case 25 of the embodiment, the base member 30 and the cover member 50 are slid relative to each other to open and close the case interior (the storage space 25a) using the gap S generated between the members 30 and 50. In addition to making it difficult for intruders to enter), it took a significant amount of time to complete the purpose of the fraud, leading to abandoning the execution of the fraud, resulting in a high fraudulent effect. A deterrent effect can be expected. That is, the gap S defined in the substrate case 25 is formed in a meandering shape that folds back and forth in the direction intersecting the inside and outside directions of the storage space 25a (front-rear direction), thereby inserting an unauthorized device from the outside of the substrate case 25. Thus, an illegal act of modifying the main control board 22 can be effectively prevented.

  In the substrate case 25 of the embodiment, the upper and lower base-side outer wall portions 32, 33 whose extension end faces the cover-side groove portions 59, 59 are formed on the inner wall surface of the base-side groove portions 39, 39, and the cover-side groove portions are formed. Upper and lower cover-side outer wall portions 52, 53 whose extending end faces the base-side groove portions 39, 39 are formed on the inner wall surfaces of 59, 59. That is, the upper and lower outer wall portions 32, 33/59, 59 in the base member 30 and the cover member 50 form the groove portions 39, 39/59, 59 and the groove portions 39, 39/59, 59 of the other members 50, 30. The gap S between the base member 30 and the cover member 50 has a meandering shape that folds back and forth in a direction intersecting the inside and outside directions of the storage space 25a. Thus, the width of the substrate case 25 in the direction intersecting with the extending direction of the groove portions 39, 39/59, 59 can be made compact while the substrate case 25 is configured to prevent illegal acts.

  Further, a part of the inner wall surface of the cover-side groove portions 59, 59 is formed by the outer peripheral end surface 24 of the main control board 22, and the main control board 22 is inserted in a meandering gap S of the board case 25 that becomes an intrusion path of the unauthorized device. Since the outer peripheral end surface 24 is exposed, it is extremely difficult to allow the unauthorized device inserted into the gap S to enter without contacting the outer peripheral end surface 24 of the main control board 22. For this reason, when an illegal act is performed by inserting an unauthorized instrument into the gap S, traces of the unauthorized act (scratches etc. due to contact with the unauthorized instrument) are left on the outer peripheral end surface 24 of the main control board 22. It becomes possible. In other words, by leaving a trace of fraudulent activity on the main control board 22 itself, which is observed intensively when checking for the presence of an abnormality, it is possible to detect fraudulent execution early and prevent oversight of fraudulent activity. Therefore, it leads to abandoning the execution of fraudulent acts, and a high deterrent effect can be expected. In addition, since it is difficult for an unauthorized device to enter the mounting surface 22a of the main control board 22, it is possible to prevent the purpose of the unauthorized activity from being achieved.

  Further, in a state where the base member 30 and the cover member 50 are slid to the closed position, the engagement protrusions 57a and 57b of the cover member 50 are fitted with the corresponding engagement recesses 32a and 33a in the base member 30, and The engaging protrusions 57a and 57b are in pressure contact with the corresponding upper and lower base-side outer wall portions 32 and 33, respectively. In other words, in a state where the engaging protrusions 57a and 57b are fitted in the corresponding engaging recesses 32a and 33a, the upper engaging protrusion 57a is pressed so as to urge the base-side upper outer wall part 32 upward. Since the lower engaging projection 57b presses the base lower outer wall 33 downward, the base upper outer wall 32 is pushed upward, or the cover upper outer wall 52 is moved downward. Even if it is going to be pushed down, the base-side upper outer wall portion 32 and the cover-side upper outer wall portion 52 can be easily displaced by the urging force of the lower engaging projection 57b and the base-side lower outer wall portion 33. Therefore, the intrusion of unauthorized equipment into the substrate case 25 can be suppressed. Similarly, even if the base-side lower outer wall portion 33 is pushed downward or the cover-side lower outer wall portion 53 is pushed upward, the upper engagement protrusion 57a and the base-side upper outer wall portion 32 are biased. The base-side lower outer wall portion 33 and the cover-side lower outer wall portion 53 cannot be easily displaced, and unauthorized equipment can be prevented from entering the substrate case 25.

  Further, when the base member 30 and the cover member 50 are slid relative to the closed position, the engagement protrusions 57a and 57b of the cover member 50 are fitted into the engagement recesses 32a and 33a. The base member 30 and the cover member 50 can be temporarily fixed at the closed position by suppressing the slide displacement of the base member 30 and the cover member 50 from the closed position to the open position. Then, by forming the concave portions 32b and 33b in the upper and lower base-side outer wall portions 32 and 33, the base member 30 and the cover member 50 are relatively smoothly moved from the open position to the closed position. The substrate case 25 that can be slid and has excellent workability such as assembly can be configured. Further, when the base member 30 and the cover member 50 are slid relative to the closed position, the upper and lower base-side outer walls 32, 33 are respectively fitted to the corresponding engaging protrusions 32a, 33a before reaching the closed position. By press-contacting, it becomes resistance of the relative sliding movement of the base member 30 and the cover member 50, and the impact at the time of closing the substrate case 25 can be relieved.

When the base member 30 and the cover member 50 are relatively slid from the closed position toward the open position, the upper and lower restricting protrusions 58 a and 58 b formed on the cover member 50 are the first members in the base member 30. The open position is defined by contacting the engagement end portions 38a and 38b of the upper and lower inner wall portions 36a and 37a. That is, when the base member 30 and the cover member 50 are slid in the opening direction, the base member 30 and the cover member 50 are not immediately separated, so that the operability when opening and closing the substrate case 25 can be improved.
Further, when the substrate case 25 of the embodiment is opened, the operation is performed with the engagement protrusions 57a and 57 of the cover member 50 fitted and pressed against the engagement recesses 32a and 33a as described above. Although the base member 30 and the cover member 50 may be opened unexpectedly and vigorously, the upper and lower restricting protrusions are formed on the engaging end portions 38a and 38b of the first upper and lower inner wall portions 36a and 37a. Since the sliding movement is restricted by the contact of 58a and 58b, it is possible to prevent the outer wall portion of the base member 30 and the cover member 50 from being cracked or broken and the sealing performance of the substrate case 25 from being impaired. At this time, the engagement end portions 38a and 38b of the first upper and lower inner wall portions 36a and 37a that are in contact with each other in the open position are provided so as to be positioned closer to the storage space 25a than the upper and lower base side outer wall portions 32 and 33. Since the upper and lower restricting protrusions 58a and 58b that are in contact with each other in the open position are provided closer to the storage space 25a than the upper and lower cover-side outer walls 52 and 53, the engaging end 38a , 38b and the upper and lower restricting protrusions 58a, 58b can be effectively prevented from cracking or breaking in the outer wall portions 32, 33, 52, 53. Here, the upper and lower restricting protrusions 58a and 58b are formed on the upper and lower cover-side outer walls 52 and 53 so as to extend in the direction intersecting the sliding direction. The impact associated with the contact with the restricting projections 58a and 58b can be effectively dispersed, and the upper and lower restricting projections 58a and 58b are damaged before the outer wall portions 52 and 53, so that the outer wall The parts 52 and 53 are protected.

  Then, the base member 30 of the embodiment has the second upper and lower portions on the engagement end portions 38a and 38b of the first upper and lower inner wall portions 36a and 37a that define the opening positions of the base member 30 and the cover member 50. Opening and closing operations of the base member 30 and the cover member 50 are configured such that the inner wall portions 36b and 37b are continuously provided and the second upper and lower inner wall portions 36b and 37b are in sliding contact with the solder surface 22b of the main control board 22. Accordingly, the movement region (second base side groove portions 39b, 39b) of the upper and lower restricting protrusions 58a, 58b and the storage space 25a can be isolated by the second upper and lower inner wall portions 36b, 37b. That is, useless gaps are not generated in the movement regions (second base side groove portions 39b, 39b) of the upper and lower restricting protrusions 58a, 58b, and they are not used as an intrusion route for unauthorized devices.

  Further, as described above, when the base member 30 and the cover member 50 are slid in the closing direction from the open position, the substrate case 25 is in a timing before the base member 30 and the cover member 50 reach the closing position. The engaging protrusions 57a and 57b are not only pressed against the corresponding upper and lower base-side outer wall portions 32 and 33, but also between the upper and lower edges 93a and 93b of the surrounding wall 93 in the base-side connecting portion 91. The connection fitting part 97 of the connection part 95 is press-contacted. This provides resistance when the base member 30 and the cover member 50 are slid from the open position to the closed position. Therefore, the member that defines the closed position before the base member 30 and the cover member 50 reach the closed position (specifically, Can alleviate the collision between the side restricting portion 35 and the fitting tube portion 67 and the side restricting portion 35 and the cover side left outer wall portion 55). It can prevent that fracture | rupture arises and the sealing property of the substrate case 25 is impaired. In addition, the stress accompanying press-contact can be disperse | distributed effectively by providing the site | part press-contacted in the case of the slide displacement of the substrate case 25 in multiple places.

(Example of change)
Note that the configuration of the gaming machine is not limited to that described above, and can be variously changed. An example is shown below.

(1) In the embodiment, in a state where the cover-side regulating wall portion faces the base-side groove portion and the base-side regulating wall portion faces the cover-side groove portion, the gap formed by each groove portion and the regulating wall portion is the inside / outside direction of the storage space However, the present invention is not limited to this. In other words, even when the gap formed by the grooves and the regulation wall portion has a meandering shape that folds three or more times in a direction intersecting the inside and outside directions of the storage space, the same effect as the embodiment can be expected. It should be noted that the insertion of the illegal member into the storage space can be made more difficult depending on the number of times the gap is folded back in the direction intersecting the inside / outside direction of the storage space. In FIG. 11A, three base side regulation wall portions 150, 150, 150 parallel to the same edge portion of the base member 30 are formed, and the base side regulation wall portions 150, 150, 150 are formed. Two base side groove portions 152, 152 are formed therebetween, and two cover side regulating wall portions parallel to the edge portion corresponding to the forming edge portion where the base side groove portions 152, 152 are formed in the cover member 50. 154, 154 are formed, and one base-side groove 156 is formed between the cover-side restriction walls 154, 154, and the grooves 154, 154, 154, 156 and the restriction walls 150, 150, 150, A configuration is illustrated in which the gap formed by 154 and 154 has a meandering shape that turns back three times in a direction intersecting the inside and outside directions of the storage space 25a.
(2) In the embodiment, the upper and lower inner wall portions 36 and 37 as the base side regulating wall portions form the inner wall surface of the base side groove portion 39, and the upper and lower cover side outer wall portions 52 and 53 as the cover side regulating wall portions are formed. Although the inner wall surface of the cover side groove portion 59 is formed, the present invention is not limited to this. That is, as shown in FIG. 11B, the base-side regulating wall 162 is formed on the base member 30 independently of the walls 160 and 160 forming the base-side groove 39, or the cover-side groove 59 is formed. Even if the cover side regulating wall 166 is formed in the cover member 50 independently of the walls 164 and 164 to be formed, a meandering shape in which the gap S is diffracted a plurality of times in the direction intersecting the inner and outer directions of the storage space 25a. Can be formed.
(3) In the embodiment, the base side groove portion and the cover side groove portion have their inner bottom surfaces (the front surface or the rear surface facing the protruding end portion of the opposite regulation wall portion) in parallel with the control board. However, the present invention is not limited to this, and the inner bottom surfaces of the base side groove portion and the cover side groove portion may be formed in an inclined shape. For example, as shown in FIG. 11 (c), the inner bottom surface 168 of the cover-side groove portion 59 is formed on the outer peripheral end surface 24 of the main control board 22 with reference to the outer end portion spaced from the outer peripheral end face 24 of the main control board 22. By inclining backward as it goes toward the inner end that is close to the inside, the unauthorized device that has entered the inner bottom surface 168 of the cover-side groove 59 is guided away from the storage space 25a by the inclination of the inner bottom surface 168. It is possible to more effectively prevent the unauthorized device from reaching the storage space 25a.
(4) In the embodiment, the outer peripheral end surface of the control board is configured to form a part of the inner wall surface of the cover side groove portion, but the outer peripheral end surface of the control board may form a part of the base side groove portion. In addition, it is possible to adopt a configuration in which a part of the groove is not formed on the outer peripheral end face of the control board.
(5) In the embodiment, the control board is attached to the cover member that covers the mounting surface of the control board. However, the control board may be attached to the base member that covers the solder surface of the control board. The electronic components are not limited to be integrated on one surface of the control board, and the electronic components may be distributed and mounted on both surfaces of the control board.
(6) In the embodiment, the main control device in which the main control board is housed in the board case has been described as an example, but the type of the control device is not limited to this. That is, the present invention can be suitably applied to a board case in which a control board on which control electronic components are mounted is housed.
(7) In the embodiment, the sliding direction of the substrate case is the left-right direction, but it may be the vertical direction. The sliding direction of the substrate case is not limited to the longitudinal direction of the substrate case, and may be the short direction of the substrate case.
(8) In the embodiment, the hook receiving portion is provided in the base side groove portion and the slide hook is provided in the cover side regulation wall portion. However, the hook receiving portion and the slide hook are provided in a portion different from the groove portion and the regulation wall portion. May be.
(9) In the embodiment, a pachinko machine has been described as an example of the gaming machine. However, the present invention is not limited to this, and any gaming machine including a board case in which a control board on which control electronic components are mounted is housed. For example, the present invention can be applied to various conventionally known gaming machines such as slot machine machines, arrange ball machines, and pinball machines.

In addition, the present application includes the following technical ideas.
(A) Regarding a gaming machine including the configuration according to claim 3,
A base-side outer wall portion (32, 33) that extends from an end portion of the base member (30) positioned in the sliding direction toward the cover member (50) and forms an outer surface of the base member (30);
A cover-side outer wall portion (52, 53) that extends from an end portion of the cover member (50) located in the sliding direction toward the base member (30) and forms an outer surface of the cover member (50);
A base-side open position defining portion (38a, 38b) provided inside the storage space (25a) from the base-side outer wall portion (32, 33) in the base member (30);
The cover member (50) includes a cover side open position defining portion (58a, 58b) provided inside the storage space (25a) from the cover side outer wall portion (52, 53),
The base-side open position defining portion (38a, 38b) and the cover-side open position defining portion (58a, 58b) are in contact with each other so that the open position of the base member (30) and the cover member (50) is defined. .
With this configuration, the base member and the cover member are slid in the opening direction by the base side opening position defining portion and the cover side opening position defining portion coming into contact with each other to define the opening position of the base member and the cover member. Even so, since the base member and the cover member are not immediately separated, the operability when opening and closing the substrate case can be improved.
Here, when the substrate case is opened, a force capable of releasing the press-contact state of the first and second engaging portions is applied to relatively slide and displace the base member and the cover member. In this case, an unexpected crack or break may occur in the outer wall portion of the base member or the cover member due to the vigorous opening of the substrate case. If such cracks and breaks occur, the sealing property of the substrate case is impaired, which may cause fraud.
On the other hand, the base-side open position defining portion is provided inside the storage space from the base-side outer wall portion, and the cover-side open position defining portion is provided inside the storage space from the cover-side outer wall portion. By defining the open position by the contact, it is possible to prevent the outer wall portion of the base member or the cover member from being cracked or broken and the sealing performance of the substrate case from being impaired.
(B) Regarding a gaming machine including the configuration described in (A),
A restricting protrusion protruding from the inner surface of the restricting wall portion (36, 37, 52, 53) provided on one (50) of the base member (30) and the cover member (50) to the inside of the storage space (25a). Portion (58a, 58b) is provided, and the restriction protrusion (58a, 58b) is provided on the other side (30) of the base member (30) and the cover member (50). , 53) is opposed to the end in the extending direction, and the end in the extending direction of the regulating protrusion (58a, 58b) and the regulating wall (36, 37, 52, 53) is in contact with the base. Configured to define the open position of the member (30) and the cover member (50), and
Sliding contact walls (36b, 37b) that are in sliding contact with the control board (22) are connected to end portions in the extending direction of the restriction walls (36, 37).
In this configuration, by connecting the sliding contact wall portion to the open position restricting portion that defines the open position of the base member and the cover member by contact with the restricting protrusion, the gap to the storage space side becomes the sliding contact wall portion. Blocked by. Therefore, even when the end portions of the restricting protrusion and the open position restricting portion are in contact with each other to define the open position of the base member and the cover member, the end portion of the open position restricting portion and the restricting protrusion are opposed to each other. In other words, there is no gap that is used as an intrusion route for unauthorized devices.
(C) Regarding a gaming machine including the configuration described in (A) above,
A base-side connecting portion (91) protruding outward from the base-side outer wall portion (32, 33) is provided, and protruding from the cover-side outer wall portion (52, 53) outwardly, the base-side connecting portion ( 91) is provided with a cover side coupling portion (95) that is unreleasably coupled to
When the base member (30) and the cover member (50) are relatively slid and displaced from the open position to the closed position, both the connecting portions (91, 95) are in pressure contact with each other to move from the closed position to the open position. Configured to suppress slide displacement.
In this configuration, when the base member and the cover member are slid in the closing direction from the open position, the first and second engaging portions are in pressure contact with each other at a timing before the base member and the cover member reach the closing position, And the base side connection part and the cover side connection part are press-contacted. As a result, the collision pressure between the wall portions that define the closed position of the base member and the cover member can be reduced, so that the wall portion that defines the closed position of the base member and the cover member is cracked or broken and the substrate case It is possible to prevent the sealing performance from being impaired. Further, when the connecting portion is broken when the substrate case is opened, the pressure contact force of the connecting portion is released, so that the base member and the cover member are opened in the opening direction when the substrate case is opened for a regular purpose. The sliding force of the connecting portions does not hinder the slide displacement.
