First, the invention that can be extracted from the present embodiment will be described while showing effects and the like as necessary.
The invention described in each means group described below is as follows. “As game machines, pachinko machines, slot machines, etc. are known. These game machines store CPU and control programs related to games. A control board on which electronic components such as ROM are mounted is provided, and a series of games are controlled by the control board.In recent years, a CPU and a ROM are integrated into one chip and mounted on the control board. In this type of gaming machine, the game contents are changed by exchanging the ROM in the control board (if the CPU or ROM is a single chip) for the purpose of obtaining illegal profits. Many fraudulent acts against the control board have been reported, and various countermeasures against fraud have been studied, for example, a plurality of box components constituting a board box. A structure having a coupling structure (so-called caulking structure) for mutual coupling is known (see, for example, Patent Document 1) The coupling structure requires destruction of a coupling portion or the like when the coupling is released. As a result, when the board box is opened, it is possible to leave an opening history due to its destruction, and when the board box is illegally opened, it can be detected. In some cases, the control board may be inspected by an external engine, etc. Therefore, in order to facilitate the work of opening the board box during this inspection, the coupling structure is actively provided with a fragile portion. cage, the fragile portion destroy (cutting, etc.) coupled by coupling structure by is released, are to allow the opening of the substrate box. "that the background art "However, even in the control board unit having the above coupling structure, still conceivable that fraud is performed. For example it is conceivable to perform so as inconspicuous destruction of fragile portions, Then rogue board box It is possible that it will not be easy to find that it has been released.

Means 1. A control board (main control board 91 etc.);
A board box (such as a board box 92) that accommodates the control board in an internal space;
The board box includes a first box structure (for example, the front side structure 101) and a second box structure (for example, the back side structure 102) that define at least a part of the internal space of the substrate box, The first box structure and the second box structure are coupled to each other,
The first box structure and the second box structure are divided into a plurality of regions with defining portions (flat plate portions 111, 131, peripheral wall portions 112, 132, etc.) that define the internal space of the substrate box, A cutting part (cutting part 150 or the like) formed so as to be easily cut so as to open the internal space more easily than when the combined state of the first box structure and the second box structure is released to open the internal space. ) Is provided in both the first box structure and the second box structure,
When the cutting portion is cut, an opening (opening 152) that is continuous with the first box structure and the second box structure and exposes at least a part of the control board is formed. To play.

  According to the means 1, the substrate box has a cut portion, and when the cut portion is cut to remove a partial region of the defining portion that defines the internal space, the substrate box has an opening. It is formed. Through this opening, a part of the control board is exposed, and the control board can be inspected and maintained.

  The cutting part is provided in both the first box structure and the second box structure, and when the cutting part is cut, a trace of cutting remains across both the box structures. . Specifically, one continuous opening is formed in both box structures. If the internal space of the board box is opened by cutting the cutting part for the purpose of cheating on the control board, the trace of the cutting remains in both box components, so that the discovery is relatively easy. be able to. For example, the cutting part may be formed across the first box structure and the second box structure. Thereby, the structure by which one opening continuous to both box structures is formed can be suitably realized.

  In addition, if the cutting trace remains only in one box structure, the board box having no cutting trace is obtained by gathering together the box structures having no trace from a plurality of control devices. Can be inconvenient. In this regard, as shown in this means, if the cutting traces remain in both the first box structure and the second box structure, the above-described inconvenience can be suppressed.

  It should be noted that the “defining part that defines the internal space of the substrate box” may be a part or all of the substrate box. In other words, it may be “a peripheral wall that defines the internal space of the substrate box” or “a wall portion that defines the internal space of the substrate box in the substrate box”.

  In addition, the “cutting portion formed so as to be easily cut” can be easily realized by applying the following configuration, for example. For example, “a plurality of through-holes (through-holes 153) penetrating into and out of the substrate box are arranged on a predetermined line, and the through-holes have a long hole shape, and the longitudinal direction of each through-hole is the predetermined "A configuration arranged along a line" may be applied, and "the cutting portion includes a plurality of through holes (through holes 153) penetrating into and out of the substrate box on a predetermined line, A configuration in which the distance dimension between the through holes arranged side by side is set smaller than the length dimension of the through holes in the juxtaposed direction may be applied.

  Furthermore, the “cutting portion formed so as to be easily cut” is formed by a plurality of through holes or the like as described above, or a predetermined portion of the Bock structure is formed to be thinner than other portions. This can be easily realized. In such a case, focusing on the fact that the opening is formed by breaking the cut portion, the “cut portion that is easily cut” can also be referred to as the “break portion that is easily broken”. Furthermore, by cutting the cut portion, the box structure is formed by combining a part of the box side structure (opening forming part) that forms a part corresponding to the opening, a main part of the box structure, and both. It is also possible to constitute so as to be separated from the cut portions to be joined. In such a case, focusing on the fact that the cutting part is separated from the box structure (opening forming part and main part), “the cutting part formed so as to be easily cut” is referred to as “the separating part formed so as to be easily separated”. It is also possible to call it.

  Mean 2. The cutting portion cuts the cutting portion to form the opening, thereby allowing the control board to move in a predetermined direction parallel to the plate surface. 2. The gaming machine according to claim 1, wherein the control board is formed so as to be removable through the opening.

  According to the means 2, the control board can be removed through the opening formed by cutting the cutting portion. In other words, the trace of removal of the control board remains in both the first box structure and the second box structure as the above-described opening is formed. Thereby, it is possible to easily grasp the fact of removal of the control board.

  In general, various elements are often mounted on the plate surface. If the removal direction of the control board is set to the surface direction of the plate surface, the operator can grasp not only the control board itself but also a portion protruding from the plate surface of the element or the like. More specifically, when a finger or the like is inserted through the opening, it is assumed that a portion (that is, an element or the like) located on the front end side in the removal direction on the control board is likely to be a grip target. Touching an element or the like when removing the control board is not desirable from the viewpoint of functional maintenance of the control board. In this regard, as described above, when removing in the direction parallel to the plate surface of the control board, it is assumed that the part of the control board located on the front end side in the removal direction is the edge of the control board, and this edge is touched with a finger or the like. Since the work can be performed by pinching, it is possible to prevent the protruding portions of the elements and the like from being actively held. As a result, it is possible to make it difficult for the inconvenience that the function of the control board is impaired due to the removal of the control board.

  It should be noted that “it is configured to be removable in a predetermined direction parallel to the plate surface of the control board based on the formation of the opening” means that the opening is formed. In addition to the configuration in which the control board can be removed immediately, the control board can be removed by taking a predetermined procedure after the opening is formed. For example, when the control board is fixed in the board box, after the opening is formed, the control board can be removed by releasing the fixed state.

Means 3. The defining portion is disposed on a side facing the first plate surface (for example, the front side flat plate portion 111) disposed on the side facing the one plate surface of the control board and the other plate surface of the control board. The second opposing wall portion (for example, the back side flat plate portion 131) and the peripheral wall portions (for example, the front side peripheral wall portion 112 and the back side peripheral wall) that are provided between the first opposing wall portion and the second opposing wall portion and form the peripheral wall of the substrate box. Part 132), and
The first box constituting body constitutes at least a part of the first opposing wall portion, and the second box constituting body constitutes at least a part of the second opposing wall portion, These first box structure and second box structure are continuous through the peripheral wall,
The cutting part defines the region including at least a part (for example, the first front side peripheral wall part 112b or the first back side peripheral wall part 132b) that inhibits the movement of the control board in the predetermined direction in the peripheral wall part. The gaming machine according to means 2, characterized in that the game machine is formed so as to be partitioned with respect to a peripheral area of the section.

  As shown in the means 2, when the control board is removed through the opening, the cutting section straddles both box components, and it is necessary to partition the area necessary for removing the control board. It is assumed that it becomes easy to become long. In such a case, there is a concern that the cutting operation of the cutting part becomes complicated and the workability is deteriorated. In this respect, according to the present means, it is possible to make it difficult to cause such inconvenience.

  If compared with the case where the control board is removed in the direction of the surface of the plate surface, that is, if the opening is formed in the first opposing wall portion or the second opposing wall portion and is removed from those openings, the peripheral wall By forming the cutting part so as to divide the region including at least the part that hinders the removal of the control board in the part, the entire length of the cutting part can be shortened while ensuring the removal function of the control board. Specifically, both the box structural bodies are arranged on both sides of the control board, and the boundary between the both box structural bodies exists around the peripheral wall portion. For this reason, when a region including at least a portion that hinders removal of the control board in the peripheral wall portion is partitioned by the cutting portion, it is possible to suppress the spread of the partitioned region and shorten the entire length of the cutting portion. Thereby, complication of the cutting operation of the cutting part can be suitably suppressed, and a practically preferable configuration can be realized.

  Means 4. The cutting portion is opposed to the first opposing wall portion, the second opposing wall portion, and the peripheral wall portion with the control board interposed therebetween in a region where the first box structural body and the second box structural body are provided. 4. The gaming machine according to means 3, characterized in that it forms a continuous or intermittent ring over a part.

  According to the means 4, it can avoid forming along the boundary part of a 1st box structure and a 2nd box structure, and can clarify the difference in arrangement | positioning of a cutting part and a boundary part. . Therefore, it is possible to clearly distinguish the boundary portion when confirming the cutting trace, and avoid confusion between the two.

  Means 5. The cutting part is formed so that a part of the control board extends from an opening formed by cutting the cutting part and removing a part of the defining part. The gaming machine according to means 3 or means 4.

  By extending the control board through the opening as shown in the means 5, it is possible to suppress complication of the work of removing the control board. For example, the substrate can be removed more easily by inserting the protruding portion between fingers without inserting a finger or the like into the substrate box.

Means 6. An element (CPU chip 93 or the like) storing a game control program is mounted on the control board, and the first opposing wall portion is opposed to a plate surface on which the element is mounted,
Of the cutting portion, a portion (first cutting portion 150a) provided on the peripheral wall portion and the second opposing wall portion is disposed on the tip side in the predetermined direction with respect to the element, Among these, the portion (second cutting portion 150b) provided in the first opposing wall is disposed around the portion facing the element in the first opposing wall. The gaming machine according to any one of means 3 to means 5.

  According to the means 6, the cutting part is arranged around the part facing the element in the first opposing wall part. Thereby, when an opening is formed by cutting the cut portion, the element can be easily exposed, and it is possible to easily contribute to facilitating inspection of the element. By arranging the cutting portion so as to bypass the element in this way, it is possible to achieve both ease of work when inspecting the element while ensuring the freedom of the mounting position of the element. For example, the control board may be attached to a part other than the part including the part facing the blocking in the board box. Thereby, exposure of the element based on formation of an opening can be suitably realized. Moreover, the part provided in the surrounding wall part and the 2nd opposing wall part among cutting | disconnection parts is arrange | positioned in the front end side in the said predetermined direction rather than an element, The removal operation | work of the removal part after cut | disconnecting a cutting | disconnection part is carried out. It can be easy. Specifically, it is possible to avoid interference with the control board by pulling out the removed portion in a direction parallel to the plate surface of the control board, but there is a concern that the work is difficult to perform by limiting the drawing direction. Such an inconvenience is assumed to become prominent as the above-described extraction operation amount increases. In this respect, if it is located on the tip side in the predetermined direction with respect to the element, it is possible to suppress an increase in the amount of extraction operation, and it is possible to contribute to ensuring workability.

  In addition, according to this means, it becomes possible to ensure the exposure of the element while disposing the cutting portion mainly on the front end side in the removal direction of the substrate box. If it can be biased and arranged on one side of the substrate box in this way, the overlap between the excised part and the control board is suppressed, and when the excised part is removed, the excised part and the control board are prevented from contacting each other. It can be done easily.

Incidentally, it is possible to obtain the same effect by applying the following configuration in place of the configuration shown in this means. That is, "the element on which the game control program is stored is mounted on the control board, and the first opposing wall portion is opposed to the plate surface on which the element is mounted, and the peripheral wall of the cutting portion is The portion provided on the portion and the second opposing wall portion is disposed on the tip side in the predetermined direction with respect to the element,
Of the cut portion, the portion provided on the first opposing wall portion is at least a first cut portion disposed on the tip side in the predetermined direction with respect to the element, and the first cut portion to the element side. And a second cutting part that is disposed with the element interposed therebetween. Can be applied to any one of means 3 to means 5 described above. According to such a configuration, when the opening is formed by cutting the cut portion, the element can be exposed and the inspection of the element can be facilitated.

  Mean 7 The gaming machine according to any one of means 2 to 6, wherein the control board has a long plate shape and is set so that a longitudinal direction of the control board is the same as the predetermined direction.

  If the removal direction of the control board matches the longitudinal direction of the control board, it is possible to suppress an increase in the size of the opening that allows the control board to be removed. That is, the overall length of the cut portion can be made relatively short. More specifically, the total length of the cutting portion can be shortened as compared with the case where the removal direction of the control board is coincident with the short direction of the control board. Thereby, complication of the cutting work of a cutting part can be controlled.

Means 8. A connector (connector 96) mounted on the plate surface of the control board;
The connector is exposed to the outside of the board box, and includes a connector opening (opening 116) formed in the defining part so as not to hinder the movement of the control board in the predetermined direction. The gaming machine according to any one of means 2 to means 7, characterized in that:

  According to the means 8, the connector can be accessed through the connector opening. The control board and an external device can be electrically connected via this connector. In addition, the connector opening is formed so as not to hinder the movement of the control board in a predetermined direction, and when the control board is removed, the connector opening and the connector are prevented from being caught. Can do. That is, workability when removing the control board can be ensured while enabling electrical connection with an external device or the like via the connector.

The gaming machine according to claim 8, wherein a distance between the control board and the control board is set larger than a protrusion dimension of the connector from the control board.

  According to the means 9, the board-side shielding part and the box-side shielding part are opposed to each other in the removal direction of the control board, and are in contact with or close to each other. As a result, it is possible to make it difficult for the inconvenience that an unauthorized tool is inserted through the connector opening. In this means, in particular, in the predetermined direction, the board side shielding part overlaps with the front side as the front side and the box side shielding part as the base side, so that inconveniences such as both being caught when removing the control board are avoided and removed. Functional security is being sought. Furthermore, the distance between the box-side shielding portion and the control board (specifically, the board surface of the control board) is set to be larger than the protruding dimension from the board surface of the connector. For this reason, the catch of both at the time of removing a control board is avoided suitably, and the removal function of the control board mentioned above is suitably secured.

The second substrate side shielding portion and the second box side shielding portion are opposed to each other in the predetermined direction with the second substrate side shielding portion as a distal end side and the second box side shielding portion as a proximal end side. And the projecting dimension of the second board side shielding part from the control board is set to be smaller than the distance between the first box side shielding part and the control board. The gaming machine described.

  As described above, when the connector moves following the movement of the control board, it is assumed that both sides of the connector opening in the predetermined direction (removal direction) are likely to be fraudulent. Therefore, by applying the configuration shown in the means 9, one of the above-mentioned parts that are likely to be fraudulent is preferably closed, but both the shielding of the part that is likely to be fraudulent and the control board It is assumed that it is difficult to simultaneously secure the removal function. In this respect, according to the present means, even when the board side shielding part and the box side shielding part are respectively arranged on both edge sides in the predetermined direction in the connector opening, each board side shielding part and box side are provided. It is possible to suppress the occurrence of inconvenience that the shielding portion is caught by the slide of the control board and the removal operation is hindered. Specifically, it is possible to avoid catching between the first box side shielding portion and the second substrate side shielding portion, and furthermore, the second substrate side shielding portion and the second box side shielding portion face each other in a predetermined direction. By doing so (more specifically, when both abut or come close to each other), it is possible to suitably suppress the insertion of an unauthorized tool. Thereby, the security | security of a removal function and the improvement of crime prevention can be made compatible.

Means 11. The shielding means includes
A shielding plate portion (protruding portion 120) that is provided on either the control substrate side or the substrate box side, stands up from the object to be arranged toward the other, and extends in the same direction as the predetermined direction. When,

  According to the means 11, the movement of the control board in the predetermined direction is guided by the shielding plate part and the guide part extending in the same direction as the predetermined direction (control board removal direction). Specifically, the distal end portion of the shielding plate portion is fitted in the guide portion, and the fitted state is maintained even if movement in a predetermined direction is performed. As a result, rattling or tilting of the control board when removing the control board can be suppressed, and the occurrence of inconvenience such as the connector being caught on the board box can be suitably avoided.

  In addition, the shielding plate portion and the guide portion can close the gap between the connector opening and the control board. Further, since the tip of the shielding plate portion is fitted in the guide portion, these wall portions and The intrusion of unauthorized tools through the boundary portion of the guide portion can be suitably suppressed. As described above, a plurality of crime prevention functions for preventing the intrusion of unauthorized tools from the portion along the predetermined direction in the connector opening and the guide plate, and a guide function for facilitating the removal of the control board. By giving this function, a practically preferable configuration can be realized.

  Means 12. The gaming machine according to any one of claims 9 to 11, wherein a plurality of the connectors are provided, and the connectors are arranged in the predetermined direction.

  By applying the configuration shown in the means 9, the means 10, etc., the box side shielding part and the board side shielding part come into contact with each other on the proximal end side or the distal end side in the removing direction of the control board in the connector opening, The access path to the internal space of the substrate box can be suitably closed. The arrangement area of the shielding part is set according to the length dimension in the direction orthogonal to the predetermined direction in the connector group, so that the gap can be suitably closed, but the joining surface of the shielding parts is large. If it becomes, when a shielding part is bent etc., there exists a possibility that a clearance gap may arise easily in a mating surface. That is, there is a concern that the function of the shielding portion is lowered due to the increase in size of the mating surfaces. Therefore, in a configuration having a plurality of connectors, the arrangement direction may be the same as the removal direction as shown in this means. By arranging the connectors in the removal direction in this manner, it is possible to suppress an increase in the length of the connector group in the direction orthogonal to the predetermined direction, and it is possible to suppress an increase in the size of the shielding portion. Thereby, a practically preferable configuration can be realized.

  Note that “providing a plurality of the connectors” includes providing a plurality of connectors of the same type. Moreover, these connectors do not necessarily need to be the same type, and include cases where a plurality of types of connectors are provided.

Means 13. A pair of connecting portions (standing pieces 170, 171 and projecting portions 174, 175) individually formed on both sides of the cut portion on the outer surface of the substrate box;
A gaming machine according to any one of means 1 to means 12, comprising a connecting tool (base part 160 of the fixing part 114) for connecting the connecting parts to each other.

  According to the means 13, since both the connecting portions are exposed to the outside of the substrate box, it is easy to perform an operation when connecting the both. Thus, by fixing each connection part formed separately by a connection tool, the excised part can be fixed easily.

  Especially in combination with means 2 and the like (configuration that allows the control board to be removed), after cutting the cutting part and inspecting the control board in the game hall, the inspected control board is again used by a gaming machine manufacturer or the like. It is conceivable to transport for reinspection. In this case, according to the present means, after the control board is accommodated in the board box, the excised part can be fixed at the original position. As a result, it is possible to suppress the inconvenience that the substrate is damaged or removed during transportation, and to perform the transportation well.

  In addition, for example, in a configuration in which the connecting portion is arranged in each region divided into two with the cutting portion interposed therebetween, each connecting portion is formed so as to avoid reaching the other provided region across the cutting portion. The following excellent effects are exhibited. That is, since the connecting part is not arranged on the cutting part, the overlapping of the cutting part and the connecting part can be avoided. Thereby, even if it employ | adopts the structure which has a connection part, it is avoided that a cutting | disconnection part becomes difficult to cut | disconnect, and the guarantee of a cutting operation can be aimed at.

  Means 14. The gaming machine according to claim 13, wherein the connector is accommodated in the board box.

  According to the means 14, the coupler is accommodated in the substrate box. For this reason, a cutting | disconnection part will be cut | disconnected with taking out of a coupling tool, and it is difficult to perform unauthorized use of a coupling tool. Further, except when it is useful, the connecting portion remains accommodated in the substrate box, and the connecting portion is less likely to be lost.

  Means 15. The gaming machine according to claim 14, wherein the control board and the board box are connected via the connecting tool.

  According to the means 15, the control board and the board box are coupled by the coupling tool provided in the board box. In other words, the connector has both a function as a connecting means for the control board and a function as a re-boxing means for re-boxing the divided substrate box. Thereby, the number of parts is reduced.

Means 16. A coupling means (such as a screw 115) that couples the coupling tool and the control board and releases a coupling state of the coupling tool and the control board when a release operation portion (head of the screw 115 or the like) is released. When,

The gaming machine according to claim 15, further comprising a second cutting portion (annular cutting portion 261) formed so as to be easily cut to open the internal space more easily than the case of opening.

  When the control board and the coupling tool are coupled as shown in the means 15, after the cutting portion is cut and the opening is formed, the coupling state between the control board and the coupling tool is released, so that the control board Detachable. As described above, by fixing the control board to the board box, the positional deviation of the control board in the board box can be suppressed, but there is a concern that the following inconvenience occurs. In other words, the presence of the coupling tool in the board box necessitates that a work or the like be inserted between the control board and the board box, and there is a concern that the work becomes complicated. Furthermore, there is a concern that a tool or the like may come into contact with the control board during the release operation. In this regard, according to the present means, a part of the substrate box is opened by cutting the second cutting part.

112b and the 2nd front side peripheral wall part 112c, 112d are continuing in the corner part. As shown in FIG. 10, on the inner surface side of the second front peripheral wall portions 112c and 112d, a front contact portion 113 is formed as a positioning portion when the main control board 91 is assembled. The front-side abutting portion 113 is erected from the inner surfaces of the second front-side peripheral wall portions 112c and 112d, and forms a protrusion that extends in the same direction as the longitudinal direction of the front-side flat plate portion 111. By positioning the element mounting surface 97 in contact with these front side abutting portions 113, positioning of the main control board 91, specifically, positioning in a direction orthogonal to the element mounting surface 97 is performed.

  Furthermore, fixing portions 114 for fixing the main control board 91 are integrally formed on the inner surfaces of the second front peripheral wall portions 112c and 112d. With the positioning as described above, the main control board 91 is fixed to these fixing portions 114, whereby the main control board 91 and the front side structure 101 are integrated. Specifically, the main control board 91 is fixed to the fixing portion 114 so as to be detachable by screws 115. Details of the fixing unit 114 will be described later.

  An opening 116 extending along the long side is provided on one long side of the flat plate portion 111. The opening 116 is formed corresponding to the connector group 96, and the terminal portion of each connector 96 is exposed to the outside of the board box 92 through the opening 116 (see FIG. 7). . The opening 116 has a substantially rectangular shape when viewed from the front of the main control device 63, and is set so that its longitudinal direction is the same as the longitudinal direction of the main control board 91. Further, the connector cover 104 is mounted on the main control board 91 (specifically, the element mounting surface 97), and a part of the connector cover 104 is exposed through the opening 116 together with the connector 96.

  Next, the connector cover 104 will be described in detail. In the following description, FIGS. 11 and 12 will be referred to as appropriate in addition to FIGS. 11A is a partial cross-sectional view taken along line AA in FIG. 7, FIG. 11B is a schematic view showing the internal structure of the main controller 63, and FIG. 12 is a partial cross-sectional view taken along line BB in FIG. It is.

  As shown in FIG. 9 and the like, the connector cover 104 is fixed to the main control board 91 by a break screw 119. More specifically, a break screw 119 inserted from the solder surface 98 side through a through hole formed in the main control board 91 is screwed to the connector cover 104. Here, the breaking screw 119 is one in which the strength of the connecting portion between the head on which the tip can be inserted into a tool such as a driver and the side on which the screw groove is formed is set low, and can be tightened further. When a predetermined force is further applied to the head by the tool at a position where it cannot be performed, the connecting portion is cut and the head is separated. That is, the break screw 119 cannot be rotated in the loosening direction using the tool after screwing. The broken screw 119 screwed to the connector cover 104 has its head separated after screwing.

  If it is possible to prevent loosening of the connection between the main control board 91 and the connector cover 104 after screwing, the fixing tool for connecting the main control board 91 and the connector cover 104 is the breaking screw 119. The known one-way screw may be used.

  The connector cover 104 includes a long plate-like base portion 124 that extends in the same direction as the arrangement direction of the connectors 96 (specifically, a rectangular shape in a front view of the main controller 63). The base portion 124 is formed with a through hole 125 corresponding to each connector 96 on a one-to-one basis. With each connector 96 inserted through the through hole 125, a plate surface on one side of the base portion 124 is formed. The entire region is in contact with the element mounting surface 97. By exposing each connector 96 through these through-holes 125, it is possible to minimize the exposure of the peripheral portion of the connector 96 on the element mounting surface 97.

  A series of peripheral walls that stand from the base portion 124 toward the front-side structure 101 (specifically, the back surface of the front-side flat plate portion 111) are integrally formed on the periphery of the base portion 124. Specifically, the peripheral wall is formed over the entire circumference of the base portion 124 except for the side facing the second peripheral wall portion 112 c of the front side structure 101. Opposing portions of the peripheral walls serve as shielding portions 126 and 127 that block the gap between the front side structure 101 and the element mounting surface 97 (see FIG. 9). On the other hand, on both short sides of the opening portion 116, partition wall portions 117 and 118 are formed corresponding to the shielding portions 126 and 127 and rising from the back surface side of the flat plate portion 111 toward the element mounting surface 97. .

  The shielding portion 126 includes a contact surface 126 a that is parallel to the partition wall portion 117 and that is in surface contact with the partition wall portion 117. Similarly, the shielding part 127 includes an abutting surface 127 a that comes into surface contact with the partition wall part 118. The contact surfaces 126a and 127a and the partition wall portions 117 and 118 are in contact with each other, so that the entire gap between the longitudinal sides of the opening 116 (specifically, the entire gap between the front structure 101 and the element mounting surface 97). It is in a blocked state.

  In addition, a plate-like portion 128 is formed on one long side of the base portion 124 so as to be continuous with the shielding portions 126 and 127 without a gap. As shown in FIG. 11A, a groove portion 129 extending in the same direction as the base portion 124 is formed at the distal end portion of the plate-like portion 128, and a protrusion that fits into the groove portion is formed on the back side of the flat plate portion 111. A strip 120 is formed. By fitting the protrusion 120 into the groove 129, a gap between the front side structure 101 and the connector 96, specifically, a gap opened to the CPU chip 93 side is closed. Further, the other long side (edge portion) of the base portion 124 is in contact with the inner wall surface of the second peripheral wall portion 112 c of the front side structure 101 in its entirety or substantially the whole. As described in detail above, the partition wall portions 117 and 118 and the protruding portion 120 on the front side structure 101 side, the shielding portions 126 and 127 and the plate-like portion 128 of the connector cover 104, the base portion 124 and the second peripheral wall Since the arrangement area of the connector 96 and the arrangement area of the main control board 91 are partitioned by the portion 112c, there arises a problem that an illegal tool or the like is inserted into the internal area of the board box 92 through the opening 116. It has become difficult. The groove portion 129 and the ridge portion 120 have a guide function for attaching and detaching the main control board 91 in addition to a shielding function that makes it difficult for an unauthorized tool or the like to enter. Details of this guide function are also provided. Will be described later.

  As described in detail above, the back-side structure 102 is fixed to the front-side structure 101 in which the main control board 91 and the connector cover 104 are integrated.

  Specifically, the back-side structure 102 has a substantially box shape opened to the main control board 91 side, and is formed on the back-side flat plate portion 131 facing the solder surface 98 and the periphery of the back-side flat plate portion 131. A back-side peripheral wall 132 standing on the main control board 91 side is integrally formed.

  The back side flat plate portion 131 has a horizontally long and substantially rectangular shape as in the front side flat plate portion 111 in a front view of the main controller 63. The back side peripheral wall portion 132 is provided on each short side of the back side flat plate portion 131 and is provided on each of the long sides of the back side flat plate portion 131 and the first back side peripheral wall portions 132a and 132b continuous to the first front side peripheral wall portions 112a and 112b. The second back side peripheral wall portions 132a and 132b are connected to the second front side peripheral wall portions 112c and 112d, and the first back side peripheral wall portions 132a and 132b and the second back side peripheral wall portions 132a and 132b are continuously formed at the corner portions. Yes.

  A stepped fitting portion 133 that is recessed toward the inside of the back side peripheral wall portion 132 is formed in the entire front end portion of the back side peripheral wall portion 132. The fitting part 133 is provided corresponding to the front side peripheral wall part 112, and the assembly position of both the structural bodies 101 and 102 is specified by the front end of the front side peripheral wall part 112 being fitted.

  In addition, a plate-like back side abutting portion 134 that faces the solder surface 98 of the main control board 91 is formed at the tip of the second back side peripheral wall portions 132c and 132d. The main control board 91 is sandwiched between the back-side contact part 134 and the front-side contact part 113, and rattling of the main control board 91 in the board box 92 is suitably suppressed. Both the contact portions 113 and 134 have a guide function when the main control board 91 is attached and detached, and details thereof will be described later.

  Next, the structure regarding fixation with the front side structure 101 and the back side structure 102 is demonstrated. An adhesive is used as a fixing means for the front side structure 101 and the back side structure 102. The adhesive is applied so as to fill the entire boundary between the front side peripheral wall portion 112 of the front side structure 101 and the back side peripheral wall portion 132 of the back side structure 102. Specifically, it is applied to the front end portion of the front side peripheral wall portion 112 and the fitting portion 133 of the back side peripheral wall portion 132. Thereby, the front side peripheral wall part 112 and the back side peripheral wall part 132 are adhere | attached, and the front side structural body 101 and the back side structural body 102 are being fixed. Thus, since the boundary part between the front side peripheral wall part 112 and the back side peripheral wall part 132 is closed, such an attempt is made to insert an unauthorized tool from the same boundary part into the internal space of the board box 92. The act is difficult to do.

  In addition, as an adhesive agent, a well-known adhesive agent can be used if the front side structural body 101 and the back side structural body 102 can be fixed, for example, an acrylic resin adhesive, a urethane resin adhesive, Ethylene-vinyl acetate resin adhesives, epoxy resin adhesives, silicone adhesives, etc. may be used, and these adhesives may be any of reaction systems, solution systems, water dispersion systems, and solid systems .

  Next, an easy opening structure for easily opening the substrate box 92 and a structure associated therewith will be described. In the following description, FIG. 13 is appropriately referred to in addition to FIGS. FIG. 13 is an explanatory diagram for explaining an easy opening structure.

  As shown in FIG. 7 and the like, the substrate box 92 is formed with a cutting portion 150 so as to partition a predetermined region in both the constituent members 101 and 102. The main controller 63 is divided into a part including the connector 96 and the fixing part 114 (hereinafter, remaining area 151a) and the other part (hereinafter referred to as removal area 151b) by the cutting part 150. By cutting the cutting portion 150 and removing the removal region 151b, an opening that extends over both the structural members 101 and 102 is formed (see FIG. 13).

  The cutting part 150 is configured by a large number (or a plurality of) through-holes 153 formed so as to penetrate into and out of the substrate box 92. Specifically, a large number of through holes 153 are formed at equal intervals so as to form an annular shape intermittently so as to partition the remaining region 151a and the removal region 151b. In other words, an intermittent annular cutting guide line is formed as the cutting portion 150.

  The through-hole 153 has a long hole shape, and is arranged such that its longitudinal direction follows the cutting guide line. By arranging the through hole 153 in this way, it is possible to contribute to facilitating cutting while suppressing an increase in the size of the through hole 153. Note that the through hole 153 may have a round hole shape. However, in such a case, there is a concern that the size of the hole directly leads to easy insertion of an unauthorized tool or the like. In other words, by increasing the hole diameter, it is possible to increase the area occupied by the flesh on the cutting guide line, which facilitates the cutting operation, but due to the increased hole diameter, insertion of unauthorized tools and the like. Can be easier. In this regard, if the through-hole 153 is formed in a long hole shape as described above, it is possible to increase the occupied area of the meat portion on the cutting guide line while ensuring the difficulty of inserting an unauthorized tool or the like. Therefore, desirably, as shown in the present embodiment, the through hole is formed in a long hole shape extending along the cutting guide line.

  An interval between adjacent through holes 153 is set so that a region between the through holes 153 can be easily cut by a tool such as a nipper or a cutter. Specifically, the distance between the through holes 153 is set to be smaller than the length of the through holes 153 in the longitudinal direction. Thereby, the cutting | disconnection part 150 becomes a weak area | region compared with another site | part in the flat plate parts 111 and 131 and the surrounding wall parts 112 and 132. FIG. In other words, in the fixed state of the front side structure 101 and the back side structure 102, the inner space of the substrate box 92 is opened by destroying the bonding part between the front side peripheral wall part 112 and the back side peripheral wall part 132 and its peripheral part. The cutting part 150 is formed so as to be easily cut so as to facilitate the opening of the internal space.

  The cutting part 150 includes a first cutting part 150a formed across both the structural members 101 and 102, and a second cutting part 150b formed in the front side structural body 101 and defining a predetermined region in the front side flat plate part 111. The first cutting part 150a and the second cutting part 150b are connected to form a substantially annular shape as a whole.

  The first cutting portion 150a is disposed across the front side flat plate portion 111, the second front side peripheral wall portion 112c, the second back side peripheral wall portion 132c, the back side flat plate portion 131, the second back side peripheral wall portion 132d, and the second front side peripheral wall portion 112d. In other words, the entire first cutting portion 150 a is positioned on a virtual plane orthogonal to the element mounting surface 97. In other words, the first cutting portion 150a includes the front side flat plate portion 111, the second front side peripheral wall portion 112c, the second back side peripheral wall portion 132c, the back side flat plate portion 131, the second back side peripheral wall portion 132d, and the second front side peripheral wall portion 112d. It arrange | positions in the area | region where the flat plate part 111 grade | etc., And the main control board 91 oppose. Furthermore, the 1st cutting part 150a is orthogonal or substantially orthogonal with respect to the boundary site | part between both the structures 101 and 102 in the area | region which opposes. Moreover, the 1st cutting part 150a is arranged near the one side part side of the main control apparatus 63, and the overlap with the arrangement | positioning area | region of the connector group 96 is avoided. More specifically, as described above, the connector group 96 (opening 116) is disposed close to the first peripheral wall 112a side, and the side opposite to the side where the opening 116 is formed, that is, the first peripheral wall. The first cutting part 150a is arranged close to the part 112b side. Thus, since the overlap between the first cutting portion 150a and the connector group 96 (opening portion 116) is avoided, it is necessary to insert a tool into the opening portion 116 when cutting the first cutting portion 150a. It does not occur, and the complication of work is suitably suppressed. Further, by arranging the first cutting part 150a close to one side, the first cutting part 150a itself is less likely to cause inconvenience that the main control board 91 is difficult to visually recognize.

  On the other hand, the second cutting unit 150 b is arranged so as to bypass the CPU chip 93 in the front view of the main control board 91. That is, the 2nd cutting part 150b is arrange | positioned so that the site | part facing the CPU chip 93 in the front side flat plate part 111 may be divided with respect to the other site | part of the front side flat plate part 111. Therefore, when the cutting unit 150 is cut and the removal region 151b is removed, the CPU chip 93 is exposed and can be removed. Further, in the second cutting portion 150b, the overlap with the connector group 96 (opening 116) is avoided similarly to the first cutting portion 150a, so that the complication of the cutting work is suitably suppressed.

  Further, as described above, the two structural members 101 and 102 are bonded to each other across their boundaries. For this reason, even if only the cutting part 150a of the front side structure 101 or the cutting part 150b of the back side structure 102 is cut, no opening is formed in the substrate box 92. In other words, by cutting the entire cutting portion 150, the opening 151 is formed, and the main control board 91 (CPU chip 93) can be exposed.

  As shown in FIG. 7 and FIG. 11, the intermediate structure 103 as a shielding member is arranged in the internal space of the substrate box 92, specifically, the space defined by the element mounting surface 97 and the front side structure 101. Yes. More specifically, the intermediate structure 103 is disposed at a position facing the cutting part 150 a formed in the front structure 101, and the cutting part 150 a is covered from the inside of the substrate box 92 by the intermediate structure 103. It is in the state.

  The intermediate structure 103 has a frame shape extending along the cutting part 150a, and is fixed to the back side of the front side flat plate part 111 by a fastener such as a screw. More specifically, a plurality of fixing portions (specifically screw holes) for fixing the intermediate structure 103 are provided on the removal region 151b side. Thus, since the intermediate structure 103 is fixed to the removal region 151b side, when the removal region 151b is separated, it is removed together with the removal region 151b. That is, the removal region 151b can be removed without cutting or destroying the intermediate structure 103 itself. As described above, since the intermediate structure 103 is not required to be cut when the substrate box 92 is opened, it is possible to apply a strong material to the intermediate structure 103, and to improve the anti-fraud function. it can.

  As shown in FIG. 11, a groove 155 that is recessed on the main control board 91 side (center side of the main control device 63) is formed on the surface of the intermediate structure 103 that faces the cutting portion 150a. The groove portion 155 has a bottom on the main control board 91 side and is formed to be opened toward the cutting portion 150a side. Further, the groove portion 155 is formed so as to be continuous over the entire area of the intermediate structure 103, and the opening edge of the groove portion 155 is the inner surface of the front-side structure body 101 (specifically, the remaining region 151a and the removal region 151b). (Both sides) In other words, the intermediate structure 103 is opposed to the back surface of the front flat plate portion 111 with the cutting portion 150 interposed therebetween, specifically, both the remaining region 151a side and the removal region 151b side. Since the groove 155 is formed in this way, even if an unauthorized tool such as a wire is inserted into the substrate box 92 through the through hole 153, the unauthorized tool enters the groove 155 of the intermediate structure 103. If it does so, even if it tries to make an unauthorized tool penetrate | invade so that the intermediate structure 103 may be bypassed, it will become difficult (refer the partial enlarged view in Fig.11 (a)).

  It is also possible to dispose the intermediate structure 103 away from the inner surface of the front structure 101. More specifically, a configuration in which the opening line of the groove 155 is not in contact with the inner surface of the front side structure 101 is also possible. Thereby, the function as a vent of the board box 92 can be given to the through hole 153 forming the cutting part 150. Even in such a case, the presence of the groove portion 155 can make it difficult for an unauthorized tool or the like to enter through the through hole 153.

  Furthermore, a configuration without the groove 155 is also possible. However, it is assumed that it is difficult to insert the cutting edge of the tool into the substrate box 92 when cutting the cutting portion 150 when the groove portion 155 is not provided. Thereby, there is a concern that it is difficult to perform the cutting operation of the cutting unit 150. Therefore, when the groove portion 155 is eliminated, it is desirable that the intermediate structure 103 bend slightly with the insertion of the tool to allow the blade edge to be inserted into the substrate box 92. Thereby, deterioration of workability | operativity can be suppressed. In addition, when the intermediate structure 103 is bent in this way and the insertion of the cutting edge of the tool into the substrate box 92 is allowed, a part of the intermediate structure 103 is inside the through hole 153. It is also possible to adopt a fitting configuration.

  Next, the configuration related to the attachment / detachment of the main control board 91 will be described in detail.

  The main control board 91 is fixed inside the board box 92 via the fixing part 114 as described above. The fixing portion 114 is a long plate-like base portion 160 that contacts the element mounting surface 97 of the main control board 91, and also contacts the element mounting surface 97, and the base portion 160 and the second front side peripheral wall portions 112c and 112d are connected to each other. And a connecting portion 161 to be connected. A screw hole 162 into which the screw 115 described above is screwed is formed in the base portion 160, and a through hole that is continuous with the screw hole 162 is formed in the main control board 91. With the base portion 160 and the element mounting surface 97 in contact with each other, a screw 115 inserted from the solder surface 98 side with respect to the through hole is screwed into the screw hole 162, whereby the fixing portion 114 and the main control board are connected. 91, that is, the front structure 101 and the main control board 91 are integrated.

  The fixing part 114 is arranged on the remaining area 151a side. For this reason, even when the removal region 151b is separated, the fixed state of the main control board 91 is maintained. More specifically, the fixing portion 114 is provided adjacent to the first cutting portion 150a described above. Thus, by arranging the fixing part 114 at a position close to the first cutting part 150a, after the removal region 151b is separated and the opening 152 is formed, the fixing part 114 can be easily connected to the fixing part 114 via the opening 152. It becomes accessible. As shown in FIG. 10, the connecting portion 161 described above has a plate shape extending from the front side to the back side of the opening 152, and outside the front side contact portion 113 and the back side contact portion 134. (It is arranged on the first cutting portion 150a side in detail) and is configured to be easily cut by a tool such as a cutter. For this reason, in the state where the removal region 151b is separated, the fixing portion 114 and the front side structure 101 can be easily separated. And the fixed state of the front side structure 101 and the main control board 91 will be cancelled | released by the connection part 161 being cut | disconnected.

  As described above, the main control board 91 is sandwiched between the contact portions 113 and 134. For this reason, even when the fixed state by the fixing portion 114 is released, the positional deviation and the fall in the substrate box 92 are suppressed. Both contact portions 113 and 134 are provided in the remaining region 151a. Specifically, it arrange | positions between the cutting part 150a and 1st surrounding wall part 112a, 132a. Thereby, the crossing of the first cutting part 150a and the contact parts 113 and 134 is avoided, and it is difficult for the inconvenience that the cutting work becomes partially difficult.

  Further, when the fixed state by the fixing unit 114 is released, the main control board 91 can be removed from the board box 92 (specifically, the remaining area 151a). In this case, the main control board 91 can be removed by sliding the main control board 91 in the longitudinal direction of the main control board 91, specifically along the both contact portions 113 and 134. In such a case, by sliding the groove portion 129 of the connector cover 104 while being fitted to the protruding portion 120 of the front-side component 101, a fall or the like when removing the main control board 91 is suitably suppressed.

  As the main control board 91 is removed, the connector cover 104 is also removed together with the main control board 91. Hereinafter, the mutual relationship between the connector cover 104 and the front side structure 101 will be described with reference to FIG.

  As described above, the shielding portions 126 and 127 of the connector cover 104 are in surface contact with the partition wall portions 117 and 118 of the front side structure 101. More specifically, the shielding portions 126 and 127 are set to be on the distal end side in the sliding direction of the main control board 91, and the partition wall portions 117 and 118 are set to be on the proximal end side in the sliding direction. , The shielding parts 126 and 127 are separated from the partition wall parts 117 and 118. The standing amount L1 of the shielding part 126 provided on the base end side in the sliding direction from the element mounting surface 97 is the gap dimension L2 between the partition wall 117 provided on the base end side in the sliding direction and the element mounting surface 97. Is set larger than. The rising amount L3 from the element mounting surface 97 of the shielding portion 127 provided on the distal end side in the sliding direction is the gap dimension L4 between the partition wall portion 118 provided on the distal end side in the sliding direction and the element mounting surface 97. Is set larger than. Thereby, the overlap between the shielding parts 126 and 127 and the partition wall parts 117 and 118 is secured.

  Further, the rising amount L1 of the shielding portion 126 and the rising amount of each connector 96 from the element mounting surface 97 are smaller than the gap dimension L4 between the partition wall portion 118 provided on the distal end side in the sliding direction and the element mounting surface 97. Is set. This avoids interference between the partition wall 118 and the shield 126 when the main control board 91 is slid. As described in detail above, the shielding portions 126 and 127 and the partition wall portions 117 and 118 are ensured to be overlapped, and interference between the shielding portions 126 and 127 and the connector 96 and the partition wall portions 117 and 118 during sliding is avoided. Therefore, the connector cover 104 and the main control board 91 can be removed together while the connector cover 104 is attached to the main control board 91.

  Here, the mutual relationship between the main control board 91 and the two components 101 and 102 will be described in detail. As described above, when the cutting portion 150 is cut and the removal area 151 is removed, the front side contact portion 113 and the back side contact portion 134, the groove portion 129 of the connector cover 104, and the ridge portion 120 of the front side structure 101 are used. The removal direction of the main control board 91 is defined. In other words, the movement of the main control board 91 in a direction other than the direction described above is restricted. In the detaching direction, the main control board 91 and the two box structural bodies 101 and 102 overlap each other. Specifically, the front-side structure 101, the main control board 91 itself, the CPU chip 93 mounted on the main-control board 91, and the CPU chip 93 mounted on the main-control board 91 are overlapped in the removal direction of the main control board 91. (Not shown) and the head of the breaking screw 119 overlap. Incidentally, FIG. 12 is a cross-sectional view showing a half of the main control device 63 on the side opposite to the side on which the cutting part 150 is formed, but each of the components 101 and 102 and the main control board 91 are also on the cutting part 150 side. Have substantially the same relationship.

  As described above, since the main control board 91 and each of the structural bodies 101 and 102 overlap each other, the cutting portion 150 formed in one of the structural bodies 101 and 102 is cut, and one of the openings 152 originally formed is cut. Even if only the part is opened, the main control board 91 is caught by the other components 101 and 102, and it is difficult to remove the main control board 91. Thus, when the main control board 91 is removed, there is a disadvantage that the main control board 91 is removed without cutting a part of the cutting part 150 (specifically, the cutting part 150 of one of the constituent members 101 and 102). It is hard to occur. In other words, with the removal of the main control device 63, cutting traces are likely to remain in both the constituent members 101 and 102.

  Next, a reclosing structure for closing the substrate box 92 again after opening the substrate box 92 and the structure accompanying it will be described. Specifically, a recombination means for separating the remaining region 151a and the removal region 151b and then recombining them will be described.

  As shown in FIG. 10, a pair of screw holes 162 are formed at a predetermined interval in the base portion 160 of the fixing portion 114 that fixes the main control board 91 and the front side structure 101. The broken screws 163 are temporarily fixed (prepared) in the screw holes 162, respectively. The base portion 160 and the breaking screw 163 are collectively separated from the front side structure 101 with the removal of the main control board 91.

  In addition, each of the structural members 101 and 102 is provided with a connecting portion that constitutes a reconnecting means together with the base portion 160 and the breaking screw 163. Specifically, as shown in FIG. 10, the second front side peripheral wall portions 112c and 112d of the front side structure 101 are provided with a pair of upright pieces (joining portions) that stand up from the outer surfaces of the second front side peripheral wall portions 112 and 112d. ) 170 and 171 are integrally molded. The standing pieces 170 and 171 are arranged at predetermined intervals on both sides of the first cutting portion 150a, and are arranged in parallel in the removal direction of the main control board 91 described above. More specifically, the standing piece 170 is arranged on the remaining area 151a side, and the standing piece 171 is arranged on the removal area 151b side. The standing pieces 170 and 171 are formed with through holes 172 and 173 extending in the same direction as the standing direction of the peripheral wall portions 112 and 112d, respectively. In addition, the back side structure 102 is integrally formed with projecting portions (joining portions) 174 and 175 corresponding to the upright pieces 170 and 171. The projecting portions 174 and 175 are opposed to the standing pieces 170 and 171 across the boundary portion between the two structural members 101 and 102. When the two structural members 101 and 102 are fixed, In contact. Screw holes 176 and 177 that are continuous with the through holes 172 and 173 are formed in the projecting portions 174 and 175.

  The distance between the screw holes 176 and 177 and the distance between the through holes 172 and 173 are the same as the distance between the screw holes 162 in the base portion 160. The base portion 160 and the breaking screw 163 separated as described above are mounted from the upright pieces 170 and 171 side, and the breaking screw 163 is screwed into the screw holes 176 and 177 through the through holes 172 and 173, whereby the base portion Through 160, the remaining region 151a and the removed region 151b are recombined.

  Here, the state of work when the main control board 91 is removed when the main control board 91 (specifically, the CPU chip 93) is inspected in the game hall will be described with reference to FIG. FIG. 14 is an explanatory view showing the state of removing the main control board 91, FIG. 14 (a) shows a completed state of the board box 92, FIG. 14 (b) shows a state where the CPU chip 93 is exposed, FIG. 14C shows a state where the main control board 91 is removed. When the main control board 91 is removed, the work is performed in the order of FIG. 14 (a) → FIG. 14 (b) → FIG. 14 (c). Hereinafter, the removal work of the main control board 91 will be described.

  As shown in FIG. 14 (a), when the main control board 91 is inspected in the game hall, the main control device 63 is removed from the gaming machine main body 12. Thereafter, as shown in FIG. 14B, the cutting portion 150 of the substrate box 92 is cut to remove the removal region 151b. Specifically, after cutting the cutting unit 150, the removal region 151 b is pulled out in the longitudinal direction of the main controller 63. As a result, the inside of the board box 92 is opened, and the element mounting surface 97 (CPU chip 93) of the main control board 91 is exposed. Since the CPU chip 93 is not soldered to the main control board 91 as described above, the CPU chip 93 can be taken out by pulling out the CPU chip 93 in the direction facing the element mounting surface 97. Thereby, the inspection of the CPU chip 93 can be performed carefully.

  Next, the connecting portion 161 of the fixing portion 114 is cut with a tool such as a nipper to release the fixing state between the main control board 91 and the remaining area 151a. Then, the removal of the main control board 91 is completed by pulling the end of the main control board 91 with a finger (see FIG. 14C).

  Here, in the configuration in which the main control board 91 (CPU chip 93) can be easily taken out from the board box 92 as described above, the main control board 91 is used by using the simplified structure. The (CPU chip 93) can be easily taken out for illegal purposes. On the other hand, when the CPU chip 93 is taken out from the substrate box 92 as described above, it is necessary to remove the removal region 151b from the substrate box 92, and a large opening 152 is formed in the substrate box 92. . Then, if the CPU chip 93 is taken out for illegal purposes, it can be easily found.

  Next, operations for temporarily housing the CPU chip 93 and the main control board 91 in the board box 92 after the inspection of the CPU chip 93 and the main control board 91 will be described with reference to FIG. FIG. 15 is an explanatory view showing how the main control board 91 is attached. FIG. 15A shows a state in which the main control board 91 is removed, and FIG. 15B shows a state in which the main control board 91 is accommodated. FIG. 15C shows a state where reopening of the substrate box 92 is restricted. When the main control board 91 is temporarily accommodated, the work is performed in the order of FIG. 15A → FIG. 15B → FIG. 15C.

  First, as shown in FIG. 15A, the fixing portion 114 (specifically, the base portion 160 and the breaking screw 163) is removed from the main control board 91. Since these fixing portions 114 are fixed by screws 115 in an easily detachable state, the detaching operation can be performed relatively easily. Next, the main control board 91 from which the fixing portion 114 has been removed is inserted into the remaining area 151a. In such a case, the main control board 91 is inserted between the contact parts 113 and 134 and the main control board 91 is slid along the contact parts 113 and 134, so that variations during assembly are less likely to occur. By pushing the main control board 91 to a predetermined position, the connector cover 104 and the partition wall portions 117 and 118 are brought into contact with each other. As a result, the opening 116 is blocked from the inside of the substrate box 92. Thereafter, the removal region 151b is returned to the position before separation, and the opening 152 is closed.

  Next, as shown in FIG. 15 (b), the breaking screw 163 is inserted into the screw holes 176 and 177 in a state where the separated fixing portion 114 (specifically, the base portion 160) is passed to both standing pieces 170 and 171. Screw it on. As a result, the upright pieces 170 and 171 and the protruding portions 174 and 175 are fixed together through the base portion 160, and the remaining region 151a and the removal region 151b are joined (see FIG. 15C). ). That is, although the cutting unit 150 is cut, the CPU chip 93 and the main control board 91 are accommodated in the board box 92. And the temporary accommodation state can be made difficult to be easily released by separating the head of the breaking screw 163 after screwing. In this way, in the state where the main control board 91 is temporarily accommodated in the board box 92, the peripheral edge portion of the main control board 91 and the peripheral wall portions 112 and 132 are in contact with each other. The positional deviation of the main control board 91 at this is suppressed.

  Here, after the CPU chip 93 and the main control board 91 are taken out from the board box 92 and carefully inspected at the game hall, the CPU chip 93 and the main control board 91 may be re-inspected by the gaming machine manufacturer. In this case, the inspection result of the CPU chip 93 and the main control board 91 may be abnormal, and the CPU chip 93 and the main control board 91 may be illegally exchanged. In such a case, assuming that the main controller 63 is transported to the gaming machine manufacturer with the opening 116 formed in the board box 92, the CPU chip 93 and the main control board 91 are damaged during the transport. There is a possibility that the CPU chip 93 and the main control board 91 cannot be re-inspected. On the other hand, the occurrence of breakage of the CPU chip 93 and the main control board 91 during the transfer is suppressed by closing the opening 116 of the board box 92 again by the removal region 151b as described above.

  In addition, an illegal acter who has illegally exchanged the CPU chip 93 or the main control board 91 may replace the main controller 63 with the regular CPU chip 93 or the main control board 91 during the transfer to the game machine manufacturer. is assumed. On the other hand, by screwing the removal area 151b with the breaking screw as described above, it is difficult to remove the removal area 151b, and it is difficult to perform an act of replacing the regular CPU chip 93 or the main control board 91 again. It becomes possible.

  In addition, as a disadvantage during transfer of the main controller 63 to the gaming machine manufacturer, when only the former is assumed, the temporary fixing of the removal region 151b does not need to be a broken screw, and a well-known removable screw is used. Just do it.

  Next, the electrical configuration of the pachinko machine 10 will be described based on the block diagram of FIG. In FIG. 16, a power supply line is indicated by a double line arrow, and a signal line is indicated by a solid line arrow.

  The main control board 91 provided in the main controller 63 incorporates a main control circuit 202 and a power failure monitoring circuit 203. A CPU chip 93 is mounted on the main control circuit 202. The CPU chip 93 temporarily stores various control programs executed by the CPU chip 93 and ROM 205 storing fixed value data, and various data when the control program stored in the ROM 205 is executed. And a RAM 206 as a memory for the memory, and various circuits such as an interrupt circuit, a timer circuit, and a data input / output circuit.

  The CPU chip 93 is provided with an input port and an output port. Connected to the input side of the CPU chip 93 are a power failure monitoring circuit 203 provided on the main control board 91, a payout control board 211 provided on the payout control device 82, and a switch group (not shown). In this case, the power failure monitoring circuit 203 is connected to a power source and launch control board 215 provided in the power source and launch control device 83, and power is supplied to the CPU chip 93 via the power failure monitoring circuit 203.

  On the other hand, a power failure monitoring circuit 203, a payout control board 211 and a relay terminal board 219 are connected to the output side of the CPU chip 93. Various commands such as a prize ball command are output to the payout control board 211. Various commands are output from the main control circuit 202 to the sound lamp control board 221 provided in the sound lamp control device 66 via the relay terminal board 219.

  The power failure monitoring circuit 203 relays between the main control circuit 202 and the power source and launch control board 215, and monitors a DC stable voltage of 24 volts that is the maximum voltage output from the power source and launch control board 215.

  The payout control board 211 performs payout control of prize balls and rental balls by the payout device 78. The CPU 212 that is an arithmetic unit includes a ROM 213 that stores a control program executed by the CPU 212, fixed value data, and the like, and a RAM 214 that is used as a work memory or the like.

  The CPU 212 of the payout control board 211 is provided with an input / output port. A main control circuit 202, a power and launch control board 215, and a back pack board 79 are connected to the input side of the CPU 212. The main control circuit 202 and the back pack substrate 79 are connected to the output side of the CPU 212.

  The power source and launch control board 215 includes a power source unit 216 and a launch control unit 217. The power supply unit 216 is connected to, for example, a commercial power supply (external power supply) in a game hall or the like. Then, based on the external power supplied from the commercial power supply, necessary operating power is generated for each of the main control circuit 202, the payout control board 211, etc., and the generated operating power is indicated by a double line arrow. This is supplied to the main control circuit 202 and the payout control board 211 through the path. The launch control unit 217 is responsible for launch control of the game ball launch mechanism 50, and the game ball launch mechanism 50 is driven when predetermined launch conditions are met.

  The sound lamp control board 221 controls the display control device 225. The CPU 222 that is an arithmetic unit includes a ROM 223 that stores a control program executed by the CPU 222, fixed value data, and the like, and a RAM 224 that is used as a work memory or the like.

  The CPU 222 of the sound lamp control board 221 is provided with an input / output port. A main control circuit 202 is connected to the input side of the CPU 222 through a relay terminal board 219 and controls the display control device 225 based on various commands output from the main control circuit 202. The display control device 225 controls the symbol display device 41 based on a display command input from the sound lamp control board 221.

  According to the embodiment described in detail above, the following excellent effects are obtained.

  The board box 92 of the main control device 63 has a cutting part 150. When the cutting part 150 is cut and the removal area 151b is removed, the CPU chip 93 storing the game control program can be removed. An opening 152 is formed in the substrate box 92. And since the cutting part 150 is formed more easily than the case where the fixed state of the front-side structure 101 and the back-side structure 102 is released, the CPU chip 93 is taken out from the board box 92 and carefully inspected at the game hall. In that case, the operation can be performed relatively easily.

  Further, when the cutting unit 150 is cut to open the internal space of the substrate box 92, the opening 152 is formed in the substrate box 92, so that the cutting unit 150 is used for the purpose of cheating on the CPU chip 93 and the like. Can be found relatively easily if the internal space of the substrate box 92 is open.

  Furthermore, in the configuration in which the cutting part 150 is provided as described above, the cutting part 150 performs a function for satisfactorily opening the internal space of the substrate box 92. Therefore, when fixing the front side structure 101 and the back side structure 102, it is not necessary to consider workability when the internal space of the substrate box 92 is opened. Thereby, fixation of both the structural bodies 101 and 102 can be strengthened.

  In the present embodiment, an adhesive is applied to the boundary portion between the front structure 101 and the back structure 102, and both the structures 101 and 102 are firmly fixed over a wide range. For this reason, it is difficult to perform such an action even if an attempt is made to insert a fraudulent tool from the enlarged boundary portion by widening the boundary portion by bending each of the structural members 101 and 102. Both the structural members 101 and 102 are firmly fixed, and accordingly, it is difficult to perform an act of illegally separating the front structural member 101 and the back structural member 102.

  As shown in FIG. 9 and the like, the cutting portion 150 is disposed across the two structural members 101 and 102. For this reason, the cutting part 150 will be cut | disconnected, and the trace of a cutting | disconnection will remain in both the structural bodies 101 and 102, respectively. Since the trace of cutting is not limited to the specific structural bodies 101 and 102 but can be confirmed in any of the structural bodies 101 and 102, it is easy to grasp such traces.

  Moreover, when the cutting part 150 is cut | disconnected normally, the trace of a cutting | disconnection will remain in both the structural bodies 101 and 102, respectively. For this reason, it is possible to make it difficult to cause inconveniences such as those in which used members 101 and 102 do not have cutting traces are gathered together to form a substrate box having no cutting traces. . That is, unauthorized diversion of the structural bodies 101 and 102 that have been properly cut can be suppressed.

  As described above, the boundary portion between the two structural members 101 and 102 is fixed (adhered) on the entire circumference. For this reason, it is difficult to access the internal region of the substrate box 92 even if only the cutting part 150 provided in either one of the constituent members 101 and 102 is cut. That is, the opening 152 is formed only by cutting the entire cutting part 150, and the internal area of the substrate box 92 can be accessed. For this reason, it is possible to make it difficult to cause the inconvenience that only one cutting portion 150 of both the constituent members 101 and 102 is cut and the other cutting portion 150 is not cut and the CPU chip 93 is accessed. This makes it easy to achieve the original purpose of leaving traces of cutting in both the structural members 101 and 102.

  The main control board 91 can be removed through the opening 152 formed by cutting the cutting portion 150 and removing the removal region 151b. By removing the main control board 91 in this way, it is easy to inspect the details of the main control board 91.

  The intermediate structure 103 is opposed to the back surface of the front side flat plate portion 111 with the cutting portion 150 interposed therebetween, specifically, both sides of the remaining region 151a side and the removal region 151b side. By cutting only the second cutting portion 150b and bending a part of the front-side flat plate portion 111, a gap enabling access to the internal space of the board box 92 is twisted, and the CPU chip 93 is passed through the gap. However, as described above, when the intermediate structure 103 comes into contact with the back surface of the front plate portion 111, a part of the front plate portion 111 is bent toward the front side of the main controller 63. It has become difficult. As a result, the removal of the CPU chip 93 is easily avoided. Further, when a gap is formed by bending a part of the front side flat plate portion 111 inward of the main controller 63, the CPU chip 93 and the front side flat plate portion 111 are brought into contact with or close to each other by an action for forming the gap. The movement of the CPU chip 93 in the removal direction becomes difficult. As described above in detail, by arranging the intermediate structure 103 corresponding to the cutting portion 150, unauthorized removal of the CPU chip 93 is suitably suppressed. Thereby, only the 2nd cutting | disconnection part 150b is cut | disconnected and it can be made hard to produce the problem that a cutting trace does not remain in the back side structure 102. FIG.

  In addition, by confirming a portion of the cutting unit 150 (specifically, the first cutting unit 150a) straddling the boundary portion between the two structural members 101 and 102, the cutting traces of the two structural members 101 and 102 are confirmed at a time. be able to. In this way, the portion where the trace confirmation can be efficiently performed is separated from the arrangement region of the connector group 96. More specifically, the connector group 96 is disposed close to one side of the main controller 63, and the portion (first cutting portion 150a) straddling the boundary portion in the cutting portion 150 is disposed close to the other, Both are separated in the arrangement direction of the connector group 96. The connector group 96 is connected to wiring (not shown) connected to other control devices. As described above, by arranging the connector group 96 and the cutting part 150 apart from each other, it is easy to ensure the visibility of the part of the cutting part 150 that straddles the boundary portion between the two structural members 101 and 102.

  In the present embodiment, in particular, the cutting unit 150 (specifically, the first cutting unit 150a) is configured to straddle the boundary portion between the two structural members 101 and 102 at a plurality of positions. In this way, by setting a plurality of portions where the trace confirmation can be performed efficiently, it contributes to the efficiency of the confirmation work. In particular, since the portions straddling these boundary portions are located on the peripheral wall portions 112 and 132, they can be visually recognized even when the main control device 63 is mounted on the mounting base 62. Thereby, at the time of confirmation of a cutting trace, work can be performed with the main controller 63 attached to the mounting base 62, and complication of the confirmation work is suppressed.

  Moreover, while the boundary part of both the box structure bodies 101 and 102 is formed so that the surrounding wall parts 112 and 132 may be followed, the cutting part 150 is formed so that it may straddle the flat plate parts 111 and 131 and the surrounding wall parts 112 and 132 Has been. That is, the cutting portion 150 is not formed along the boundary portion between the two structural members 101 and 102, but is formed separately from the boundary portion. For this reason, the cutting part 150 and the boundary part can be clearly distinguished, and confusion between the two can be suppressed.

  After inspecting the main control board 91 (especially the CPU chip 93) by cutting the cutting unit 150 in the amusement hall, the inspected main control device 63 is transported for inspection by a gaming machine manufacturer or the like again. Can be considered. In the present embodiment, after removing the removal region 151b, it is possible to fix it in the original position again. As a result, it is possible to make it difficult to cause inconveniences such as the main control board 91 being damaged during transportation or the main control board 91 being illegally replaced.

  As shown in FIG. 9, when the main control device 63 is assembled in the manufacturing process, the main control board 91 is sandwiched between the two components 101 and 102. Thereby, the opening part 116 and the connector cover 104 are fit together suitably, and it is hard to produce a clearance gap between both. When the board box 92 is opened and the main control board 91 is removed, or when the main control board 91 is temporarily stored in the board box 92 after the main control board 91 is removed, the longitudinal direction of the main control device 63 is set. The main control board 91 is slid toward the front so that it can be attached and detached. When such a main control board 91 is attached or detached, the work can be carried out with the connector cover 104 attached, thereby facilitating the work. Since it is not necessary to remove the connector cover 104, the connector cover 104 can be fixed by the break screw 119. Thereby, it is possible to suppress the formation of a gap for inserting an unauthorized tool into the opening 116 by releasing the fixed state of the connector cover 104 or the like.

  Furthermore, both the front-side structure 101 and the connector cover 104 are provided with surfaces intersecting with the slide attachment / detachment direction of the main control board 91, and they are in contact with each other so that they are in the same direction as the slide attachment / detachment direction of the main control board 91. It is possible to close the gap opened toward That is, the partition wall portions 117 and 118 and the shielding portions 126 and 127 are in contact at the mounting completion position. For this reason, it is difficult for the inconvenience of accessing the internal space of the board box 92 through the opening 116 through which the connector 96 is exposed. In particular, since the arrangement direction of the connectors 96 and the sliding direction of the main control board 91 are set to be the same direction, the mating surfaces of the partition wall portions 117 and 118 and the shielding portions 126 and 127 are made relatively small. This makes it difficult to perform the above-mentioned fraudulent acts. Hereinafter, a structure that suppresses the generation of a gap by bringing the surfaces into contact with each other as described above is simply referred to as a “surface matching structure”.

  As described above in detail, the initial mounting direction of the main control board 91 is the surface direction of the element mounting surface 97, and the slide mounting / removing direction is parallel to the element mounting surface 97, thereby closing the opening 116. The expansion of the range that requires the matching range is suppressed. Temporarily, the board box formed by sandwiching the main control board 91 from the short side or the long side of the main control board 91 is configured such that the main control board 91 can be slidably attached and detached as shown in the present embodiment. The following inconveniences are likely to occur if it is to be realized. That is, when the main control device 63 is first assembled, the mounting direction of the main control board 91 is easily restricted. For example, the main control is performed in parallel with the element mounting surface 97 with respect to one of the components constituting the board box. It is necessary to insert the substrate 91. As described above, in the mounting in the direction parallel to the element mounting surface 97, the range that requires surface alignment for closing the gap in the connector exposing opening 116 as described above tends to increase. In such a case, if an opening is formed in the board box and the main control board is slidably attached to and removed from the opening, the initial mounting is performed so that the opening straddles both components that define the internal space of the board box. It is necessary to cross the direction and the slide attachment / detachment direction (for example, orthogonal). For this reason, it is assumed that the range which requires the surface matching mentioned above further expands. From the circumstances detailed above, the main controller 63 shown in the present embodiment is considered to have an excellent crime prevention function because the intrusion of unauthorized tools around the connector 96 is suitably suppressed.

(Second Embodiment)
In the present embodiment, with respect to the board box of the main control device, the arrangement of the cutting part and the structure associated therewith, the connector and the structure associated therewith, and the structure relating to the release of the fixed state by the fixing part are the first embodiment described above. It is different from the form. Therefore, the configuration of main controller 230 in the present embodiment will be described below. 17 is a perspective view for explaining the configuration of the main control device 230 in the present embodiment, FIG. 18 is an exploded perspective view of the main control device 230 viewed from the front side, and FIG. 19 is an exploded view of the main control device 230 viewed from the back side. It is a perspective view.

  The main control device 230 includes a main control board 231 and a board box 232 in the same manner as the main control apparatus 63 in the first embodiment. Similarly to the substrate box 92 in the first embodiment, the substrate box 232 includes a front-side component 233 and a back-side component 234 as a plurality of box components. The main control board 231 is accommodated in the internal space defined by the combination of H.234. In addition, both the components 233 and 234 (substrate box 232) are formed with a cutting portion 235 in the same manner as the both components 101 and 102 in the first embodiment, and the substrate box 232 has the cutting portion. Divided into a remaining region 236 and a removal region 237 with 235 as a boundary.

  However, the cutting part 235 in the present embodiment is formed so as to be substantially the same as the first cutting part 150a shown in the first embodiment, and the second part that partitions a predetermined region in the front side flat plate part 111. A portion corresponding to the cutting portion 150b is omitted. Specifically, the cutting part 235 is disposed on a virtual plane orthogonal to the longitudinal direction of the main control device 230 (main control board 231), and has an annular shape as a whole. For this reason, even if the cutting part 235 is cut and the removal region 237 is removed, the front side of the CPU chip 238 remains covered with the front side structure 233 (specifically, the front side flat plate part 239). Thus, even if the removal region 237 is removed, the removal of the CPU chip 238 is maintained by the front side flat plate portion 239 as long as the main control board 231 is not removed.

  The cutting part 235 is configured by arranging a plurality of through holes 245 penetrating into and out of the substrate box 232 as in the first embodiment. On the other hand, a shielding member that corresponds to the intermediate structure 103 shown in the first embodiment and blocks these through holes 245 from the inside of the substrate box 232 is omitted. For this reason, air can move into and out of the substrate box 92 through the through holes 245, and the air permeability of the main controller 230 is ensured. Since these through holes 245 are biased and arranged on one side of the main controller 230, even if an unauthorized tool is inserted from the through hole 245, it is difficult to access the CPU chip 238. Yes.

  A plurality of openings 247 that expose the connector 246 are provided at positions away from the cutting portion 235 in the front side structure 233. More specifically, the openings 247 are formed in a one-to-one correspondence with the connectors 246, and the connectors 246 are individually exposed through the openings 247.

  Here, based on FIG. 20A, differences from the first embodiment in the peripheral portion of the connector 246 will be described. FIG. 20A is a partial cross-sectional view taken along the line CC in FIG. In the first embodiment, the connector cover 104 and the partition wall 117 are provided to close the gap between the connector 96 and the opening 116. However, in the present embodiment, the connector cover 104 and the like are provided. Is omitted. Instead, each opening 247 has a size substantially the same as the outer shape of each connector 246, and the amount of standing of the connector 246 from the element mounting surface 248 is approximately equal to the gap dimension between the element mounting surface 248 and the front side flat plate portion 239. By being equivalent, generation | occurrence | production of the clearance gap formed between these connectors 246 and the opening part 247 is suppressed.

  The main control board 231 is fixed to the front side structure 233 via the fixing part 250 as in the first embodiment (see FIG. 19). Specifically, the screw 251 inserted through the through hole 249 of the main control board 231 is screwed into the screw hole 252 formed in the fixing portion 250 from the solder surface 253 side of the main control board 231. The main control board 231 is fixed. As in the first embodiment, the fixed portion 250 includes a connecting portion 254 and a base portion 255, and the connecting portion 254 and the base portion 255 are in contact with the element mounting surface 248.

  In the first embodiment, the connecting portion 161 is cut with a tool such as a cutter. However, since the connecting portion 161 is in contact with the element mounting surface 97, a tool can hit the element mounting surface 97 when cutting the connecting portion 161. In the present embodiment, such a configuration that can suitably avoid the contact of the tool with the element mounting surface is provided. Hereinafter, a configuration related to contact avoidance will be described with reference to FIG. 20B in addition to FIG. FIG. 20B is a partial cross-sectional view taken along the line DD in FIG.

  As shown in FIG. 19, an annular cutting portion 261 having an intermittent annular shape is formed at a portion corresponding to each screw 251 in the back side flat plate portion 258 of the back side structure 234. Similar to the cutting part 150, the annular cutting part 261 is formed by arranging a plurality of through holes 262 penetrating into and out of the substrate box 232 in an annular shape (specifically, in a circular shape). Further, the annular cutting portion 261 is arranged so as to partition a portion overlapping the screw 251 with respect to other portions in the front view of the main controller 230. These annular cutting portions 261 are formed in such a size that a tool such as a driver can be inserted through an opening formed by cutting the annular cutting portion 261, and the tool inserted through the opening. Thus, the screw 251 can be removed.

  Hereinafter, the state of work when the main control board 231 is attached and detached when the main control board 231 (specifically, the CPU chip 238) is inspected in the game hall will be described with reference to FIGS. FIG. 21 is an explanatory view showing how the main control board 231 is removed, and FIG. 22 is an explanatory view showing how the main control board 231 is attached (temporarily accommodated). 21A shows a completed state of the substrate box 232, FIG. 21B shows a state where the substrate box 232 is opened, and FIG. 21C shows a state where the main control board 231 is released. FIG. 21 (d) shows how the main control board 231 is released when viewed from the back side of the board box 232. When the main control board 231 is removed, operations are performed in the order of FIG. 21A → FIG. 21B → FIG. 21C. Hereinafter, the removal work of the main control board 231 will be described.

  The process from the removal of the main control device 230 to the removal of the removal region 237 is the same as that in the first embodiment, and a description thereof will be omitted. As shown in FIG. 21C, in a state where a part of the main control board 231 is exposed from the board box 232, the annular cutting part 261 is cut with a tool such as a nipper or a cutter, so that the back-side structure 234 is circled. A shaped opening 263 is formed. A tool such as a screwdriver is inserted from these openings 263, and the screw 251 is removed by the tool. As a result, the fixed state between the main control board 231 and the board box 232 is released, and the main control board 231 can be removed. In this embodiment, the substrate box 232 is opened by cutting the cutting unit 235 and then the main control board 231 is released from the fixed state. However, this process may be performed in reverse. That is, first, the fixed state of the main control board 231 is released. Thereafter, the cutting unit 235 may be cut and the substrate box 232 may be opened.

  In the present embodiment, even if the removal region 237 is removed, if the fixed state of the main control board 231 is maintained, the removal of the CPU chip 238 is kept difficult, and the removal of the main control board 231 is performed. As a result, the removal of the CPU chip 238 is facilitated.

  Next, operations for temporarily housing the CPU chip 238 and the main control board 231 in the board box 232 after the inspection of the CPU chip 238 and the main control board 231 will be described with reference to FIG. 22A shows a state in which the main control board 91 and the fixing portion 250 are removed, FIG. 22B shows a state in which the main control board 231 is accommodated, and FIG. 22C shows reopening of the board box 232. Indicates the regulated state. When the main control board 231 is temporarily accommodated, the work is performed in the order of FIG. 22A → FIG. 22B → FIG. 22C.

  As described above, when the main control board 231 is unfixed and the main control board 231 is removed, the fixing portion 250 is left in the board box 232 (in detail, it is connected to the front side structure 233). It is left alone). By cutting off these fixing portions 250 with a tool such as a nipper or a cutter, the fixing portion 250 can be used as a means for recombining the remaining region 236 and the removal region 237 as in the first embodiment. Subsequent procedures relating to temporary accommodation are the same as those in the first embodiment, and a description thereof will be omitted.

  According to the present embodiment described in detail above, the following excellent effects can be obtained in addition to some of the effects of the first embodiment. That is, when the fixed state of the main control board 231 is released, the main control board 231 (specifically, the element mounting surface 248) can be suitably protected. Specifically, since the connecting portion 254 as a cutting target is in contact with the element mounting surface 248, it is assumed that it is difficult to cut only the connecting portion 254 in a state where they are in contact with each other. In this regard, in the present embodiment, the main control board 231 and the connecting portion 254 can be separated in advance, so that when cutting the connecting portion 254, the tool penetrates the connecting portion 254 and the element mounting surface 248. Inconveniences such as touching are less likely to occur.

  Further, since the connecting portion 254 can be cut after the main control board 231 is removed, it is easy to secure a work space in the board box 232. Thereby, since a tool can be applied to both surfaces of the connecting portion 254, a double-edged tool such as a nipper can be used instead of a single-edged tool such as a cutter.

  Further, an annular cutting portion 261 for removing the screw 251 is formed on the back side structure 234 (the solder surface 253 side in the board box 232). For this reason, even when an unauthorized tool or the like is inserted through the through-hole 262 constituting the annular cutting portion 261, access to the element mounting surface 248 side is suitably suppressed. This is the same even after the opening 263 is formed. Even if an unauthorized tool is inserted through the opening 263, the element mounting surface 248 (for example, the CPU chip 238) is less likely to be illegal. By this. The improvement of workability and the security of crime prevention can be achieved at the same time.

(Other embodiments)
In addition, it is not limited to the description content of each embodiment mentioned above, For example, you may implement as follows. Incidentally, the configurations of the following different modes may be applied individually to the configurations of the above embodiments, or may be applied in combination with each other.

  In addition, regarding part names and member names that are commonly used in a plurality of embodiments, only the part numbers and member numbers used in one embodiment are described, but this is described. It is not limited to. That is, it is also possible to apply the part number and member number used in other embodiments specified in advance.

  (A) In each of the above embodiments, the substrate box 92 is formed using the two structural bodies 101 and 102 that cover the main control board 91 from the front side and the back side, but this may be changed as follows. That is, the substrate box may be formed using two components that cover the main control board 91 from both sides in the longitudinal direction or the short side direction of the main control board 91. In such a case, it is considered that both components are likely to exist in a portion of the substrate box that faces the plate surface of the main control substrate 91. It is preferable to provide a cutting portion straddling both components at a portion of the substrate box that faces the plate surface of the main control substrate 91. For example, it is good to provide the cutting part which divides | segments the area | region containing the boundary site | part between both structures. As in the above-described embodiments, the main control board 91 can be removed in a direction parallel to the plate surface after the cutting portion is cut by partitioning a part of the peripheral wall portion by the cutting portion. Is desirable.

  (B) In each of the above embodiments, an adhesive is used as a coupling means for coupling the two structural members 101 and 102. However, it is possible to change this and use a fixture such as a break screw or a seal seal. Good. Moreover, it is good also as a structure which uses combining each of these coupling | bonding means.

  Moreover, it is also possible to make it the structure which unites both the structural bodies 101 and 102 using an ultrasonic wave and a heat | fever. Furthermore, although it was set as the structure couple | bonded in the whole boundary part of both the structures 101 and 102, it is not limited to this, It is good also as a structure which couple | bonds only the predetermined site | part among the whole boundary part. However, preferably, binding sites may be set at both the boundary site in the remaining region 151a and the boundary site in the removal region 151b.

  The seal seal will be briefly described. When the seal seal is peeled off after being stuck, the pressure-sensitive adhesive layer remains on the sticking target and cannot be stuck again. By providing the seal, it is possible to find out if the substrate box 92 is illegally opened. Such a seal seal may be pasted so as to straddle the boundary portion between the two structural members 101 and 102.

  (C) In each of the above-described embodiments, the main control board 91 is fixed to the front structure 101. However, the main control board 91 may be changed and fixed to the back structure 102. Specifically, the fixing portion 114 may be provided on the back side structural body 102 instead of the front side structural body 101. However, when this another example is applied to the second embodiment, an annular cutting portion for removing a screw screwed to the fixing portion is formed on the front side structure 233 side. Therefore, an opening is formed on the element mounting surface 248 side by cutting the annular cutting portion. Since the element mounting surface 248 is easily subject to fraud, it is not preferable that such an opening be formed. Therefore, it is desirable to provide the fixing portion on the front side structure 101 side.

  (D) In each of the above embodiments, the connecting portion 161 of the fixing portion 114 is in contact with the element mounting surface 97. However, this is changed so that a predetermined amount is provided between the connecting portion 161 and the element mounting surface 97. It is good also as a structure by which the clearance gap is ensured. Specifically, as shown in FIG. 23A, the connecting portion 271 may be offset to the front side flat plate portion 111 side while ensuring the contact between the base portion 270 and the main control board 91. That is, the fixing portion 272 may be formed such that the base portion 270 and the connecting portion 271 form a step shape from the element mounting surface 97 side toward the front plate portion 111 side. Thereby, the contact between the tool and the element mounting surface 97 when cutting the connecting portion 271 can be easily avoided. Further, by widening the gap between the connecting portion 271 and the element mounting surface 97, a tool can be inserted between the connecting portion 271 and the element mounting surface 97 when the connecting portion 271 is cut. Become. Thereby, use of a nipper etc. is attained and it can contribute to the simplification of cutting work, for example.

  In addition, a work space (tool gap) around the connection portion 161 can be secured by cutting away the portion of the main control board 91 that faces the connection portion 161.

  (E) In each of the above embodiments, the fixing portion 114 is used as a fixing means for temporarily fixing the remaining region 151a and the removal region 151b. However, the present invention is not limited to this. A fixing means for temporarily fixing the remaining area 151 a and the removal area 151 b may be provided separately, and the fixing portion 114 may be used only for fixing the main control board 91.

  In addition, the breaking screw 163 used for temporarily housing the main control board 91 is configured to be housed (prepared) inside the board box 92. However, the breaking screw 163 may be prepared separately from the board box 92. .

  (F) In each of the above embodiments, the portion of the cutting unit 150 that straddles the boundary portion of each of the structural bodies 101 and 102 is configured to be orthogonal to the boundary portion, but is not necessarily limited thereto. That is, both need only intersect and do not need to be orthogonal. However, when both are close to parallel, it is assumed that the tool is likely to be displaced along the boundary portion when the portion straddling the boundary portion is cut. Therefore, it is desirable to make both orthogonal.

  (G) In each of the above-described embodiments, the cutting unit 150 has a configuration in which a plurality of linear portions are connected. However, it is possible to change the configuration so that the cutting unit 150 has a curved shape as a whole.

  (H) A sealing seal that closes the cutting portion 150 may be provided. In addition, a seal seal having an IC tag that transmits a response wave including unique ID information in response to a calling wave from a predetermined scanner may be used. Thereby, it becomes difficult to produce the problem that the cutting trace of the cutting part 150 is concealed.

  (I) It is also possible to adopt a configuration in which the cutting portions 150 formed in both the constituent members 101 and 102 overlap the inside and outside of the substrate box 92. Specifically, as shown in FIG. 23 (b), the peripheral wall portions 277 and 278 of the two structural members 275 and 276 are arranged to overlap each other. And you may provide the cutting part 279 in both the surrounding wall parts 277 and 278 so that it may overlap, seeing from the outer surface side of these surrounding wall parts 277 and 278, respectively.

  (J) In each of the above embodiments, the cutting portion 150 formed in the substrate box 92 is configured to form an intermittent ring, but may be configured to form a continuous ring. Hereinafter, modifications of the cutting part 150 formed in the substrate box 92 will be described with reference to FIGS.

  (J-1) The cutting portion 280 shown in FIG. 23C is provided by forming a bottomed groove instead of a through-hole penetrating into and out of the substrate box 92. In addition, the said groove | channel is not limited to a cross-sectional V shape, A U shape may be sufficient. Even in this configuration, since the cutting portion 280 is formed in the substrate box 92, it is possible to obtain the same effect as the first embodiment with respect to the opening of the internal space of the substrate box 92. Further, in this configuration, the cutting unit 280 does not function as a vent, but the act of trying to insert an unauthorized tool through the cutting unit 280 is not performed, so the intermediate structure 103 is not provided. It is good.

  (J-2) The cutting part 290 shown in FIG. 23 (d) is not a through-hole or groove that penetrates into or out of the substrate box 92, but is made of a material that is weaker than the material constituting the other part of the substrate box 92. It is provided by applying. Even in this configuration, since the cutting portion 290 is formed in the substrate box 92, it is possible to obtain the same effect as the first embodiment with respect to the opening of the internal space of the substrate box 92. Further, in this configuration, the cutting unit 290 does not function as a vent, but the act of trying to insert an unauthorized tool through the cutting unit 290 is not performed, so the intermediate structure 103 is not provided. It is good.

  (K) In each of the above embodiments, the substrate box 92 is divided into two in the longitudinal direction of the substrate box 92 by the cutting portion 150. However, this is changed to two minutes in the short direction of the substrate box 92. It is good also as a structure to be made.

  (L) In each of the above embodiments, the arrangement direction of the connectors 96 and the slide attachment / detachment direction of the main control board 91 (longitudinal direction of the main control device 63) are set to be the same. It is not a thing. For example, the arrangement direction of the connectors 96 and the slide attaching / detaching direction of the main control board 91 may be crossed. However, in the first embodiment, when the arrangement direction of the connectors 96 and the slide attaching / detaching direction of the main control board 91 intersect, the mating surface between the partition wall portion and the connector cover in the opening 116 is likely to be large. . Such an enlargement of the mating surface is not preferable from the viewpoint of preventing unauthorized intrusion. Therefore, desirably, the arrangement direction of the connectors 96 and the slide attachment / detachment direction of the main control board 91 may be set to be the same.

  (M) In each of the above embodiments, the provisional housing configuration after the inspection of the CPU chip 93 and the main control board 91 may be omitted. Further, when the CPU chip 93 and the main control board 91 are temporarily accommodated after inspection, the plate surface on which the CPU chip 93 is mounted can be temporarily accommodated toward the back side flat plate portion 131 side of the back side structure 102. It is good also as a structure.

  (N) In each of the above embodiments, the CPU chip 93 in which the CPU, the ROM, and the RAM are integrated into one chip is mounted on the main control board 91. Instead, a ROM-dedicated element is mounted on the main control board 91. May be. In this case, at least with respect to the element dedicated to the ROM, each configuration of the substrate box 92 in the first embodiment, specifically, the part facing the element dedicated to the ROM in the front side flat plate part 111 is formed by the second cutting part 150b. A partitioning configuration may be applied.

  In the above embodiment, the CPU chip 93 is used. However, the present invention is not limited to this. Any chip may be used as long as it stores at least a program for performing various types of lotteries such as jackpots and probability changes in games, and performs the various types of lotteries. Moreover, what is necessary is just a chip | tip which affects the lottery result at least.

  (O) In the first embodiment, the intermediate structure 103 has the groove 155. However, the intermediate structure 103 may have no groove 155. For example, it is good also as a structure which makes the intermediate structure a plate shape facing the front side flat plate part 111. Further, the attachment target of the intermediate structure 103 may be the remaining area 151a instead of the removal area 151b.

  (P) In each of the above embodiments, the first peripheral wall portion 112b is partitioned by the cutting portion 150, that is, the first peripheral wall portion 112b is removed by cutting the cutting portion 150. It is not limited to. For example, it is good also as a structure by which a part of 1st surrounding wall part 112b is divided by a cutting part, and the 1st surrounding wall part 112b opening is formed by cut | disconnecting a cutting part. The opening cut by exposing at least a part of the main control board 91 may be formed across both the constituent members 101 and 102.

  (Q) In each of the above embodiments, the standing pieces 170 and 171 and the protruding portions 174 and 175 used when rejoining the remaining region 151a and the removal region 151b are arranged side by side in the same direction as the sliding direction of the main control board 91. However, the present invention is not limited to this, and it suffices if they are arranged at least on the remaining region 151a side and the removal region 151b side, respectively. However, desirably, the upright pieces and the protruding pieces are provided on both sides of the cutting portion 150.

  Further, in both the remaining region 151a and the removal region 151b, both the constituent members 101 and 102 are fixed to each other with an adhesive. For this reason, even if the upright pieces 170 and 171 are omitted, the regions 151a and 151b can be temporarily connected.

  (R) In each of the above-described embodiments, the main control board 91 or a configuration accompanying the main control board 91 (specifically, solder) and the constituent bodies 101 and 102 overlap each other in the sliding direction (removal direction) of the main control board 91. However, this may be changed as follows. Specifically, the main control board 91 itself and the components 101 and 102 may overlap in the sliding direction (removal direction) of the main control board 91.

  (S) In the second embodiment, the screw 251 for connecting the main control board 231 and the fixing portion 250 is attached from the solder surface 253 side, that is, the head of the screw 251 is located on the solder surface 253 side. However, this can be changed as follows. That is, a configuration in which the screw 251 is attached from the element mounting surface 248 side, in other words, a configuration in which the head of the screw 251 is positioned on the element mounting surface 248 side may be employed. In such a case, the annular cutting portion 261 may be formed on the front side structure 233 instead of the back side structure 234. However, when the annular cutting portion is formed on the front side structure 233 in this way, if an unauthorized tool or the like is inserted through the annular cutting portion, the element mounting surface 248 may be easily accessed. Occurs. Such an inconvenience is assumed to be remarkable when the annular cut portion is cut and an opening is formed. Therefore, it is preferable that the annular cutting portion is desirably disposed on the back side structure 234, specifically, on the solder surface 253 side.

  (T) In each of the above-described embodiments, the boundary between the two structural members 101 and 102 and the cutting portion 150 are orthogonal to each other. Is possible. However, as the boundary part and the cutting part approach in parallel, there is a concern that the tool may easily become along the boundary part when cutting the cutting part. Therefore, it is desirable to make both orthogonal.

  (U) In each of the above embodiments, the main control board 91 can be removed from the board box 92 through the opening 152. However, this is changed to restrict the removal of the main control board 91. Also good. For example, a restricting portion (for example, a stopper) that restricts further movement in the removal direction may be formed in a state in which almost the entire main control board 91 protrudes through the opening 152. Accordingly, it is possible to suitably suppress the occurrence of inconvenience that the main control board 91 is illegally replaced while ensuring workability during inspection of the main control board.

  (V) The configuration applied to the board box of the main control device in each of the above embodiments may be applied to other control devices such as the sound lamp control device 66, the payout control device 82, the power source and the launch control device 83. Good.

  (W) In each of the above embodiments, the present invention is applied to the pachinko machine 10 provided with the upper plate 57a and the lower plate 58a as the outer storage unit, but instead, a single outer storage unit is provided. The present invention may be applied to a pachinko machine. Further, by providing the power failure monitoring device separately from the main control device 63, the main control board 91 may be configured to have only the function of the main control circuit 202.

  (X) Other types of pachinko machines different from the above-described embodiments, such as pachinko machines that release a predetermined number of times when a game ball enters a specific area of a special device, or games in a specific area of a special device The present invention can also be applied to a pachinko machine that generates a big hit when a ball enters, a pachinko machine equipped with another accessory, an arrangement ball machine, a sparrow ball, and the like.

  Also, a non-ball-type gaming machine, for example, a plurality of reels with a plurality of types of symbols attached in the circumferential direction, starts rotation of the reel by inserting a medal and operating a start lever, and a stop switch is operated. If a specific symbol or a combination of specific symbols is established on the effective line visible from the display window after the reel has stopped after a predetermined time has passed, a privilege such as paying out medals is given to the player The present invention can also be applied to a slot machine.

  The slot machine includes a box-shaped casing opened forward and a front door that closes the opening of the casing, and a control board device is accommodated in the casing. In this case, whether or not the cutting portion is cut by arranging the control board device so that the portion where the cutting portion is formed in the substrate box of the control board device is visible when the front door is opened. This can be easily confirmed.

  In addition, the gaming machine main body that is supported by the outer frame so as to be openable and closable is provided with a storage unit and a capture device, and the start lever is operated after a predetermined number of game balls stored in the storage unit are captured by the capture device. Thus, the present invention can also be applied to a gaming machine in which a pachinko machine and a slot machine are fused, which starts rotating the reel.
