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 the following means group is “ Pachinko gaming machines, slot machines, etc. are known as a plurality of types of gaming machines. These gaming machines store CPUs and control programs related to gaming. 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, for the purpose of obtaining illegal profits, the ROM in the control board (or the chip if the CPU or ROM is integrated into a single chip) is exchanged to change the game contents. Many fraudulent actions against the control board such as changing have been reported, and various countermeasures against fraud have been studied in the past. A coupling means (so-called caulking structure) is known for coupling to (see, for example, Patent Document 1.) The coupling means is configured to require destruction when the coupling is released. In addition, it is also known that the degree of freedom of arrangement of the board box is improved by adopting a configuration in which the board box is mounted on the gaming machine main body side via the base member. Regarding the background art of “ there is a restriction on the removal of the substrate box by being coupled to the pedestal member by the coupling means described above. ” However, even in the configuration including the coupling means, It is conceivable that fraudulent acts will be carried out, for example, by skillfully removing the coupling means, the board box may be opened or the control board may be taken away. Also, if the number of coupling means is increased or the structure of the coupling means is complicated in order to make it difficult to open the board box, etc., the assembly work of the board box etc. will be complicated. That is, it is considered that the more complicated the assembly work of the board box or the like becomes more conspicuous as the security is improved .

Means 1. A control board (main control board 91, etc.) for controlling the game,
An internal space is formed, and the internal space includes a substrate box (substrate box 92) in which the control board is accommodated.
The board box is
A first box structure (for example, the back-side structure 101) and a second box structure (for example, the front-side structure 102) that form at least a part of the internal space of the substrate box by being combined with each other;
A defining portion (for example, the back-side peripheral wall portion 121 and the front-side configuration of the back-side structure 101) that defines the relative movement direction of the first box structure and the second box structure in a predetermined direction when the first box structure and the second box structure are combined. A front peripheral wall 131) of the body 102;
A regulation means (for example, a locking mechanism 175) for regulating separation of the first box structure and the second box structure,
The regulating means is
A first locking portion (back side locking portion 180) provided in the first box structure,
A second locking part (front side locking part 190) that is provided in the second box structure and restricts separation of the two box structures by being locked to the first locking part;
A first deforming portion (an arm portion 181 of the back side locking portion 180) that displaces the first locking portion to a side where the locking state with the second locking portion is released by elastic deformation;
A second deforming portion (the standing portion 191 of the front side locking portion 190) that displaces the second locking portion to the side where the locking state with the first locking portion is released by elastic deformation;
Based on the relative movement of both the box structures to the side where the first box structure and the second box structure are combined among the predetermined directions defined by the defining part, the first locking part and A guide portion (guide portions 158a, 199a) for shifting the second locking portion to the locked state;
Based on the elastic deformation of the first deformation part and the second deformation part, both the first locking part and the second locking part are displaced to the side where the locked state is released, so that A gaming machine, wherein the locked state of the first locking portion and the second locking portion is released.

  According to the means 1, based on the relative movement of the two box structural bodies in the predetermined direction defined by the defining section, the separation of the box structural bodies is regulated. Specifically, the first locking portion and the second locking portion are displaced by the displacement of the first deformable portion and the second deformable portion based on the relative movement in the combination direction of the two box components. To shift to the locked state. As described above, since a separate operation for regulating the separation of the box structure is not required, it is possible to suppress complication of the assembly work of the substrate box.

  As described above, since the restriction of removal is performed based on the combination work of the box structure, it is possible to suitably suppress the inconvenience that the work is not performed due to an error such as forgetting the work.

  Further, both the first locking portion and the second locking portion are displaced to the side where the locked state is released based on the elastic deformation of the first deformation portion and the second deformation portion. Since the locked state is released, it is easy to release the lock. Thereby, improvement in crime prevention can be expected.

Mean 2. The first deformable portion and the second deformable portion are formed so as to allow elastic deformation to a predetermined side,
The displacement direction of the first locking portion toward the side where the locking state is released is opposite to the displacement direction of the second locking portion toward the side where the locking state is released. The gaming machine according to means 1, characterized in that the first deformation part and the second deformation part are arranged.

  When using a configuration that requires displacement of both locking portions to release the locked state as shown in the means 1, the displacement of both locking portions is increased in accordance with the increase in the allowance between the locking portions. It is assumed that the amount needs to be increased. In order to realize a stable locking state, it is desirable to increase the allowance. However, due to this, the displacement of the locking portion increases, leading to an increase in the size of the regulating means and an increase in the size of the board box. It becomes easy to do and is not preferable.

  In this regard, as shown in this means, if each deforming part is arranged so that the displacement direction at the time of releasing the lock is opposite, even if the structure in which both the locking parts are displaced together is adopted, It is possible to easily secure the allowance while suppressing an increase in the amount of displacement. As a result, it is possible to suppress the occurrence of inconveniences such as insufficient allowance due to assembly variation, etc., contribute to stabilization of the locked state, and suppress increase in size of the regulating means. Can do.

Means 3. The first locking portion is arranged at a predetermined interval from the first locking portion, and when the first locking portion is displaced to the locking state release side, the first locking portion abuts on the first locking portion to prevent the displacement. A stopper (opposite wall 124 of the backside structure 101);
The second locking portion is disposed at a predetermined interval from the second locking portion. When the second locking portion is displaced to the unlocked side of the locking state, the second locking portion abuts on the second locking portion to prevent the displacement. The gaming machine according to means 1 or 2, further comprising a stopper portion (the first front side peripheral wall portion 132 of the front side structure 102).

  According to the means 3, the displacement of each locking portion is prevented by the first stopper portion and the second stopper portion. The amount of displacement of each locking portion can be defined by each stopper portion, and displacement of the locking portions beyond that assumed in advance can be avoided. As a result, it is difficult to cover the displacement amount of the other locking portion by displacing only one locking portion and increasing the displacement amount. The displacement of the part can be made indispensable.

  That is, to release the locked state, when separating the first box structure and the second box structure, both locking portions are displaced in different directions, and the two box structures are relatively moved in the separating direction. It is necessary to let For example, it is necessary to relatively move both box components in a state in which one locking portion is operated with one hand and the other locking portion is operated with the opposite hand. For this reason, it is difficult for one person to perform the separation work of the board box, and unauthorized access to the control board (for example, the CPU chip) and unauthorized removal of the control board (for example, the CPU chip) are preferably performed. Can be suppressed.

  As described above in detail, ensuring the workability and improving the crime prevention performance can be suitably achieved by making it easy to assemble the board box and making the board box difficult to separate. .

  It is also possible to avoid deformation exceeding the elastic deformation range (plastic deformation), and protection of the first deformable portion and the second deformable portion can be achieved. Thereby, it is possible to favorably maintain the function of the restricting means, that is, the function of restricting the separation of the two box structural bodies.

Means 4. The displacement direction to the release side of the locked state in the first locking portion and the displacement direction to the release side of the locked state in the second locking portion are set in opposite directions,
The first locking portion is arranged at a predetermined interval from the first locking portion, and when the first locking portion is displaced to the locking state release side, the first locking portion abuts on the first locking portion to prevent the displacement. A stopper (opposite wall 124 of the backside structure 101);
The second locking portion is disposed at a predetermined interval from the second locking portion. When the second locking portion is displaced to the unlocked side of the locking state, the second locking portion abuts on the second locking portion to prevent the displacement. A stopper portion (first front side peripheral wall portion 132 of the front side structure 102),
The first stopper portion and the second stopper portion have a wall shape facing each other, and the first locking portion and the second locking portion are located in a region sandwiched between the first stopper portion and the second stopper portion. The gaming machine according to means 1, characterized in that is arranged.

  According to the means 4, in addition to the effects shown in the means 2 and 3, there are the following special effects. That is, the first locking portion and the second locking portion are disposed in a region sandwiched between the first stopper portion and the second stopper portion that form a wall shape that faces each other. Thereby, the access to each locking part can be made difficult by both stopper parts. Further, even when the locking portion is accessed, it is possible to make it difficult to perform an unauthorized operation of the locking portion by both the stopper portions. Therefore, opening the substrate box can be made more difficult.

  As described above in detail, it is possible to contribute to the multi-function of the stopper portion by providing the both stopper portions with a restriction function for restricting access and operation to the locking portion.

  Means 5. The maximum displacement amount (gap dimension X12) of the first locking portion defined by the first stopper portion is based on a hooking margin (hanging margin X10) between the first locking portion and the second locking portion. And the maximum displacement amount (gap dimension X14) of the second locking portion defined by the second stopper portion is the difference between the first locking portion and the second locking portion. The gaming machine according to means 3 or 4, wherein the gaming machine is set to be smaller than an allowance.

  According to the means 5, the maximum displacement amount of the first locking portion and the maximum displacement amount of the second locking portion are set smaller than the allowance between the locking portions. Thereby, the structure shown in the means 4 etc. mentioned above is suitably realizable. Specifically, even if only one of the locking portions is displaced, the locking state of both locking portions is not released, and the locking state of both locking portions is maintained. That is, it is possible to make the displacement of both locking portions indispensable for releasing the locked state.

  In addition, although it is possible to apply the technical idea (that is, the relationship between the displacement amount and the allowance) shown in this means to the means 3, in such a case, “the first locking portion and the second locking portion” The “hanging allowance” differs depending on which locking portion is used as a reference. Specifically, in the first locking portion, an allowance with the second locking portion in the displacement direction of the first locking portion is shown, and in the second locking portion, the displacement direction of the second locking portion. Fig. 3 shows the allowance for engagement with the first locking portion.

  By the way, this means is described as follows: “Even if the first locking portion is displaced so as to be the maximum displacement amount defined by the first stopper portion, the locking state of the both locking portions is maintained. In addition, even when the second locking portion is displaced so as to have the maximum displacement amount defined by the second stopper portion, the locking state of the both locking portions is maintained. The gaming machine according to means 3 or means 4 characterized in that both stopper portions are formed. "

  Means 6. The gaming machine according to means 4 or 5, wherein the first stopper portion is provided in the second box structure, and the second stopper portion is provided in the first box structure. .

  According to the means 6, the first locking portion is sandwiched between the first stopper portion and the second locking portion provided in the second box structure, and the second locking portion is the first box configuration. It is sandwiched between the second stopper portion and the first locking portion provided on the body. Therefore, even if the first box structure and the second box structure are displaced in the displacement direction of the locking portion, the relationship between the first locking portion and the second locking portion is assumed. It is possible to make it difficult for the inconvenience that the locked state is easily released, and it is possible to contribute to the stabilization of the locked state.

  Specifically, if each box component is displaced to the side where both locking portions approach, both locking portions approach each other, so the hanging allowance does not decrease. On the other hand, when each box structure is displaced to the side where both the locking portions are separated, the engagement allowance of the both locking portions is reduced in accordance with the amount of displacement. However, based on this positional deviation, the first stopper portion approaches the second locking portion, and the gap dimension between the first stopper portion and the second locking portion (that is, the maximum displacement amount of the second locking portion allowed). And the first locking part approaches the second stopper part, and the gap dimension between the second stopper part and the first locking part (that is, the maximum displacement amount of the first locking part allowed) also decreases. Become. That is, the maximum displacement amount of each locking portion is also reduced with the decrease in the allowance. Therefore, even if the first box structure and the second box structure are misaligned, it is avoided that the locked state is easily released.

  If a configuration opposite to the configuration shown in this means (a configuration in which the first stopper portion is provided in the first box structure and the second stopper portion is provided in the second box structure) is adopted, The first stopper portion and the first locking portion move together with the displacement of the relative position between the one box structure and the second box structure (specifically, the displacement in the displacement direction of the locking portion). 2 The stopper part and the second locking part move together. In such a case, the engagement between the engaging portions is reduced depending on the positional deviation amount, and the engaging state can be easily released. Therefore, the configuration shown in this means is preferably adopted.

  In addition, “the first stopper portion is provided in the second box structure” means that the first stopper portion is integrally formed with the second box structure, and in addition to the second box structure. The case where the first stopper portion formed separately is mounted on the second box structure is shown. “The second stopper portion is provided in the first box structure” means that the second stopper portion is integrally formed with the first box structure and is different from the first box structure. The case where the 2nd stopper part formed with the body is mounted | worn with respect to the 1st box structure is shown.

Mean 7 The first locking portion constitutes a part of an outer wall portion (outer groove wall portion 157 of the back side structure 101) that forms the outline of the first box structure, and the first stopper portion is At least in a predetermined region including the first locking portion in the outer wall portion, facing the outer wall portion,
The distance between the peripheral portion of the first locking portion and the first stopper in the outer wall is smaller than the distance between the first stopper and the first locking. 6. The gaming machine according to 6.

  According to the means 7, even if the first stopper portion is pushed from the outside of the substrate box, the first stopper portion maintains the predetermined gap with the first locking portion, and the outer wall portion. In contact with the peripheral portion of the first locking portion. Thereby, it can suppress that the external force applied to the 1st stopper part is disperse | distributed by an outer wall part, and the influence by the external force reaches with respect to a 1st latching | locking part.

  For example, the outer wall portion and the first stopper portion may be formed so that the outer wall portion and the first stopper portion come into contact with each other on at least both sides of the first locking portion in a state where both the box structural bodies are combined.

  Means 8. The means according to any one of means 1 to 7, wherein a space surrounding the restricting means is formed by combining the first box structure and the second box structure. Gaming machine.

  According to the means 8, since the restricting means is disposed in the space formed by disposing the control board at a predetermined position, it is difficult to access the restricting means. Thereby, it can contribute to the further improvement of crime prevention.

  In addition, it is desirable that the “surrounding space” is constituted by a closed space. By accommodating the restricting means in the closed space, access to the restricting means can be made more difficult.

Means 9. Each box component has a partition wall portion (for example, the back side peripheral wall portion 121 and the flat plate portions 110 and 130) having a substantially constant thickness that partitions the internal space and the external space of the substrate box,
The gaming machine according to any one of means 1 to 8, wherein the restricting means is accommodated in an internal space partitioned by the partition wall portion.

  According to the means 9, the restricting means is accommodated in the internal space of the substrate box, and the exposure of the substrate box to the external space is suppressed. Thereby, it becomes difficult to access the restricting means, and it is possible to suitably prevent the substrate box from being illegally opened.

  In the configuration in which the restricting means is accommodated in the internal space of the board box, the exposure of the restricting means can be suppressed and the crime prevention performance can be improved as described above, but the access to the restricting means becomes difficult. There is a concern that the transition to the stop state becomes complicated. In this respect, as shown in the means 1 etc., by adopting a configuration in which the restricting means (each locking portion) is shifted to the locked state based on the change in the relative position of the box structure during the combination work The shift operation to the locked state can be performed without directly touching the regulating means. Thereby, it can contribute to the improvement of crime prevention property, avoiding the complication of the transfer operation | work to a latching state.

  In addition, since it is not necessary to form an opening or the like for shifting to the locked state in the substrate box, a preferable configuration can be realized from the viewpoint of preventing unauthorized entry.

  Note that the “substantially constant wall thickness” shown in the present means includes a wall having a constant wall thickness and a protrusion such as a rib for the purpose of reinforcement. Further, in a configuration having a plurality of “partition wall portions”, the thickness of each of the partition wall portions may be the same or different.

  Incidentally, in the combination with the means 7, the “outer wall portion” may be the same as the “partition wall portion”, or the “outer wall portion” and the “partition wall portion” may be different.

  Means 10. At least an outer portion of the locking portion in the partition wall portion of each box structure is formed of a transparent or translucent material so that the locking portion can be visually recognized from the outside of the substrate box. A gaming machine according to claim 9.

  When the restricting means (specifically, the locking portion) is configured to be accommodated in the internal space of the substrate box, improvement in crime prevention can be expected, but the following inconvenience may occur. That is, when the box components are recombined after the locking portions are broken by forcibly separating the box components in the separating direction, it may be difficult to grasp such an opening fact. In this regard, as shown in this means, if the locking portion (locking state) can be confirmed from the outside of the board box, the above-described inconvenience can be suitably avoided, and if forcibly opening is performed. Even so, it is easy to confirm the traces that accompany it, and a practically preferable configuration can be realized.

Means 11. The displacement direction to the release side of the locked state in the first locking portion and the displacement direction to the release side of the locked state in the first locking portion are set in opposite directions,
The first locking portion is arranged at a predetermined interval from the first locking portion, and when the first locking portion is displaced to the locking state release side, the first locking portion abuts on the first locking portion to prevent the displacement. A stopper (opposite wall 124 of the backside structure 101);
The second locking portion is disposed at a predetermined interval from the second locking portion. When the second locking portion is displaced to the unlocked side of the locking state, the second locking portion abuts on the second locking portion to prevent the displacement. A stopper portion (first front side peripheral wall portion 132 of the front side structure 102),
The first stopper portion and the second stopper portion have a wall shape facing each other, and the first locking portion and the second locking portion are located in a region sandwiched between the first stopper portion and the second stopper portion. Is placed,
11. A gaming machine according to any one of means 1 to means 10, wherein one of the stopper portions is arranged inside the board box with respect to the other.

  According to the means 11, in addition to the same effects as the means 4, the following special effects are obtained. That is, one of the stopper portions is disposed on the inner side of the other. Similarly, one side of each latching | locking part will be arrange | positioned inside the other. For this reason, when trying to illegally access the stopper part or the locking part from the outside of the board box, the access to the one stopper part and the one locking part arranged inside is to the other locking part or the like. It will be more difficult. In order to release the locked state, it is necessary to displace both the locking portions. If it is difficult to displace at least one of the locking portions, it is possible to suitably suppress the locked state from being illegally released.

  For example, the stopper portions and the locking portions may be arranged in the longitudinal direction of the control board. As a result, even if an unauthorized tool or the like is inserted from the outside of the substrate box, both the locking portion and the inner stopper portion disposed on the inner side of the outer stopper portion itself by the outer stopper portion. Can be prevented, and a practically preferable configuration can be realized.

  Means 12. The relative movement direction of the first box structure and the second box structure defined by the defining portion is a displacement direction to the side of releasing the locking state in the first locking portion, and the first The means according to any one of means 1 to means 11, which is set so as to intersect with both directions of the direction of displacement toward the side of releasing the locking state in the two locking portions. Gaming machine.

  In the configuration shown in the means 1 to means 11, the relative movement direction when separating the first box structure and the second box structure is the same as the displacement direction of any of the locking portions toward the locking release side. In this case, the displacement of one of the locking portions and the movement of the two box components in the separating direction can be performed simultaneously by one operation. More specifically, it is assumed that one box can be operated with one hand and the other locking section can be operated with the other hand while the two box components are separated. Such integration of operations is not preferable from the viewpoint of regulating the separation of both box structures.

  In this regard, according to the present means, since the relative movement of both box components and the displacement of the locking portion can be set to be in independent directions, it is difficult to integrate the operations as described above. The opening of the substrate box can be preferably controlled.

Means 13.

Specifically, when the first deforming portion and the second deforming portion are both displaced based on the movement of the board box in the mounting direction, the first locking portion and the second locking portion are displaced and locked. Transition to state. As described above, since a separate operation for restricting the removal of the substrate box is not required, it is possible to suppress complication of the operation of attaching the substrate box.

  Furthermore, when removing the substrate box, it is necessary to displace both locking portions in different directions and move the substrate box in the removal direction. For example, it is necessary to further move the substrate box in a state where one locking portion is operated with one hand and the other locking portion is operated with the opposite hand. For this reason, it is difficult for one person to perform the removal work of the board box, and it is preferable that the board box is taken away with the control board (stolen) or the control board is replaced with the board box.

You may make it provide a clearance over the perimeter.

  The main control board 91 is screwed to the board fixing boss 114 by screwing a break screw 117 from the element mounting surface 97 side of the main control board 91. Here, the breaking screw 117 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 breaking screw 117 cannot be rotated in the loosening direction using the tool after screwing. If it is possible to prevent the main control board 91 and the main board fixing boss 114 from being loosened after screwing, the main control board 91 and the main board fixing boss 114 are connected. The fixture (coupling means) is not limited to the breaking screw 117 and may be a well-known one-way screw. The breaking screw 117 screwed to the board main fixing boss 114 has a head portion separated after screwing.

  The board temporary fixing boss 115 and the box temporary fixing boss 116 are respectively used after the board box 92 is opened in the inspection of the main control board 91 in the game hall. This will be described in detail later, and will not be described here.

  In addition, a back side peripheral wall 121 that stands on the main control board 91 side and surrounds the main control board 91 is integrally formed over the entire outer peripheral edge of the back side flat plate part 110. The back-side peripheral wall 121 is a plate-like portion having a substantially constant thickness formed along each outer peripheral edge of the back-side flat plate 110, specifically, is disposed on both sides in the longitudinal direction of the main control board 91 and sandwiches the main control board 91.

That is, the back side structure 101 has a substantially box shape opened to one side, and the main control board 91 is accommodated in the back side structure 101.

  Between the partition frame part 113 and each 1st back side surrounding wall part 122, the opposing wall part 124 which opposes these 1st back side surrounding wall parts 122 is each provided. Each of these opposing wall portions 124 is integrally formed with the back-side flat plate portion 110 and has a plate shape continuous with both the second back-side peripheral wall portions 123. More specifically, the opposing wall portion 124 is erected from the back side flat plate portion 110, and the amount of erection is configured to be equal to the amount of erection of the first back side peripheral wall portion 122. The space between the first back-side peripheral wall portions 122 and the opposing wall portions 124, that is, the groove portion 125 formed by both the wall portions 122 and 124 and a part of the back-side flat plate portion 110, has both configurations. A part of the restricting means for restricting the removal (that is, separation) of the bodies 101 and 102 is accommodated. Details of the restricting means will be described later.

  As shown in FIGS. 8 and 9, the front side structure 102 has a front side flat plate portion 130 that faces the element mounting surface 97 of the main control board 91. That is, the main control board 91 is sandwiched between the back side flat plate part 110 of the back side structure 101 and the front side flat plate part 130 of the front side structure 102. The front side flat plate portion 130 has a substantially rectangular shape when viewed from the front side of the main control board 91, and is formed so that its outer shape is slightly larger than the outer shape of the back side flat plate portion 110. The surface (inner surface) on the main control board 91 side is in contact with the entire front end edge of the back-side peripheral wall 121 and the opposing wall 124. That is, the open part of the back side structure 101 is closed by the front side flat plate part 130 as described above.

  A front side peripheral wall 131 standing on the main control board 91 side is integrally formed over the entire outer peripheral edge of the front side flat plate part 130. The front side peripheral wall 131 is a plate-like portion having a substantially constant thickness formed along each edge of the front side flat plate 130, specifically, disposed on both sides in the longitudinal direction of the main control board 91. It has a pair of first front side peripheral wall portions 132 facing each other and a pair of second front side peripheral wall portions 133 disposed on both sides in the short direction of the main control board 91 and facing each other with the main control board 91 therebetween. The first front side peripheral wall part 132 and the second front side peripheral wall part 133 are connected via a corner part. That is, by the front side flat plate portion 130 and the front side peripheral wall portion 131, the front side structure 102 has a substantially box-like shape released to the main control board 91 side.

  The first front peripheral wall 132 has its own inner wall 132a facing the outer wall 122a of the first back peripheral wall 122, and each inner wall 132a contacts almost the entire area of the outer wall 122a. It is formed as follows. Similarly, the inner wall surface 133a of the second front side peripheral wall portion 133 is opposed to the outer wall surface 123a of the second back side peripheral wall portion 123, and each inner wall surface 133a is in contact with almost the entire area of the outer wall surface 123a. It is formed as follows. As a result, the open part of the front side structure 102 is closed by the back side structure 101, and the main control board 91 is enclosed by the back side peripheral wall part 121 and the front side peripheral wall part 131 in an inner and outer double. ing.

  The back-side peripheral wall 121 and the front-side peripheral wall 131 have a predetermined direction (in this embodiment, the surface direction of the element mounting surface 97 and the relative direction of movement of the two structural members 101, 102 when the two structural members 101, 102 are assembled. A function as a prescribing means for prescribing in the same direction) and a function as a restraining means for suppressing displacement of both constituent members 101 and 102 in a direction crossing the predetermined direction after the combination is completed. ing. When combining the two structural members 101, 102, the inner wall surfaces 132a, 133a of the front peripheral wall portion 131 are placed along the outer wall surfaces 122a, 123a of the back peripheral wall portion 121, so that the combination guidance is provided in the predetermined direction. Made. In other words, combinations from directions other than the predetermined direction are limited.

  And in the state where both components 101 and 102 are combined with each other, the inner wall surfaces 132a and 133a of the front side peripheral wall portion 131 are in contact with the outer wall surfaces 122a and 123a of the back side peripheral wall portion 121. The positional deviation in the direction intersecting the predetermined direction is suppressed. Note that the peripheral wall portions 121 and 131 can also be referred to as “guide means” when attention is paid to the fact that guidance to a predetermined combination completion position is performed when the two structural members 101 and 102 are combined.

  A plurality of slits 141 are formed in each second back side peripheral wall portion 123 of the back side structure 101 by cutting out a part of the second back side peripheral wall portion 123 and opened to the front side flat plate portion 130 side of the front side structure 102. Is provided. These slits 141 are arranged so as to continue to the space sandwiched between the first back-side peripheral wall portion 122 and the opposing wall portion 124. The front-side structure 102 is provided with an insertion portion 142 that is paired with each of the slits 141 and is inserted into each of the slits 141. The insertion part 142 stands up from the front side flat plate part 130, has a plate shape facing the first front side peripheral wall part 132, and fits into the fitting part 143 fitted to the slit 141 and the groove part 125, It is comprised by the contact part 144 contact | abutted to the 2nd back side surrounding wall part 123. FIG. The thickness of the insertion portion 142 is formed to be equal to the gap size of the slit 141, the fitting portion 143 is fitted into the slit 141, and the contact portion 144 is formed on the inner surface of the second back side peripheral wall portion 123. Based on the contact, the relative positions (specifically, the relative position in the predetermined direction and the relative position in the direction crossing the predetermined direction) of both the constituent members 101 and 102 are specified. That is, the second back side peripheral wall portion 123, the slit 141, and the insertion portion 142 constitute positioning means for both the constituent members 101 and 102.

  A long hole portion 145 extending along the long side is formed on one long side of the front side flat plate portion 130. The long hole portion 145 is surrounded by the front peripheral wall portion 131 and the partition wall 146 of the front flat plate portion 130.

  A connector plate 104 is disposed between the front side structure 102 and the main control board 91 so as to close the long hole portion 145. The connector plate 104 is screwed to the back side of the front structure 102 (specifically, it is fixed in a detachable state). A plurality of through holes 149 are formed in the connector plate 104 in a one-to-one correspondence with a predetermined connector group provided on the main control board 91.

  As described above, the front side structure 102 in which the connector plate 104 is integrated covers the element mounting surface 97 of the main control board 91 with respect to the back side structure 101 in which the main control board 91 is integrated. It is combined. In this case, the back side peripheral wall part 121 (specifically, the end surface 119) of the back side structure 101 and the front side peripheral wall part 131 of the front side structure 102 are in contact with each other, and the open portion of the front side structure 102 to the back surface side is present. It is blocked by the back side structure 101. Various elements mounted on the element mounting surface 97 of the main control board 91 are accommodated in a region between the main control board 91 and the front side structure 102.

  Further, in a state where the back side structure 101 and the front side structure 102 are combined, a predetermined connector mounted on the element mounting surface 97 enters the through hole 149 corresponding to the connector plate 104. In this state, the connector is exposed on the surface side of the front structure 102. The position of the predetermined connector on the main control board 91 may be changed for each model. In such circumstances, the connector plate 104 is provided as described above, so that only the connector plate 104 is changed for each model. The front-side structure 102 and the back-side structure 101 can be made common for each model.

  Incidentally, the plate-like portion 147 in which the through hole 149 of the connector plate 104 is formed is superimposed on the element mounting surface 97 of the main control board 91 and is provided upright from the plate-like portion 147 of the connector plate 104. Further, the standing portion 148 overlaps the partition wall 146 of the front side flat plate portion 130 on the inner side of the front side flat plate portion 130. Accordingly, in the configuration in which the connector plate 104 is provided as described above, the element mounting surface 97 of the main control board 91 is covered with the front side structure 102 and the connector plate 104 except for the connector, as shown in FIG. It has been broken.

  The back side structure 101 and the front side structure 102 are fixed to each other in the combined state as described above. Thus, a rectangular box-like (substantially rectangular parallelepiped) substrate box 92 having a predetermined internal space is formed, and the main control substrate 91 is accommodated in the internal space of the substrate box 92. In this case, the entire element mounting surface 97 of the main control board 91 is opposed to the front side structure 102 in which the connector plate 104 is integrated, and the entire solder surface 98 of the main control board 91 is the back side. It faces the structure 101.

  As shown in FIG. 5, the main controller 63 having the above configuration is configured so that the surface of the front structure 102 faces the back of the pachinko machine 10 and the edge on the side where the connector plate 104 is provided is positioned on the upper side. It is installed. Incidentally, when the gaming machine main body 12 is opened from the outer frame 11 to the front of the pachinko machine 10 in the state of being installed in the game hall, the back side of the gaming machine main body 12 can be visually recognized. In this case, the main control device 63 constitutes the back portion of the gaming machine main body 12, and further, since the surface of the front structure 102 faces the back of the pachinko machine 10 as described above, By opening to the frame 11, the surface of the front structure 102 can be visually recognized. The main controller 63 may be entirely or partially covered with the back pack unit 15 from the rear. Even in this case, since the back pack 71 is formed to be transparent, the surface of the front structure 102 can be visually recognized by opening the gaming machine body 12 with respect to the outer frame 11.

  In addition, although the removal (separation) of the back side structural body 101 and the front side structural body 102 is regulated by a plurality of regulating means, details regarding the configuration relating to the removal regulation of both the structural bodies 101 and 102 will be described later.

  Here, an opening easy structure for easily opening the substrate box 92 will be described. In the following description, FIGS. 10 to 12 will be referred to as appropriate in addition to FIGS. FIG. 10 is an explanatory diagram showing a partially enlarged front view of the substrate box 92 for explaining the easy opening structure, and FIGS. 11 and 12 are explanatory diagrams for explaining the easy opening structure.

  As shown in FIG. 7, a box-side cut portion (box-side weak portion) 151 is formed on the front-side flat plate portion 130 of the front-side structure 102 so as to partition a predetermined region of the front-side flat plate portion 130. Yes. The box-side cutting portion 151 includes a large number (or a plurality of) through-holes 152 formed so as to penetrate the front-side flat plate portion 130 into and out of the substrate box 92.

  Specifically, the large number of through holes 152 are formed at equal intervals along the periphery of the front side flat plate portion 130, and the large number of through holes 152 are arranged so as to surround a predetermined region of the front side flat plate portion 130. That is, the box-side cutting portion 151 is formed in an intermittent annular shape surrounding a predetermined region of the front-side flat plate portion 130. In other words, an intermittent annular cutting guide line is formed as the box-side cutting portion 151. These through holes 152 have a long hole shape, and are arranged so that the longitudinal direction thereof follows the cutting guide line. By arranging the through hole 152 in this way, it is possible to contribute to facilitating cutting while suppressing an increase in the size of the through hole 152. The box-side cutting portion 151 is formed in a rectangular frame shape, specifically, a rectangular frame shape. In addition, the area partitioned by the box-side cutting part 151 in the front side flat plate part 130 is an area facing the CPU chip 93 of the main control board 91 and its periphery in the front side flat plate part 130. Note that the through-hole 152 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 jig or the like. That is, 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 increases the hole diameter, thereby making it easy to insert an illegal jig or the like. Can be. In this regard, if the through hole 152 is formed in a long hole shape as described above, it is possible to increase the occupied area of the meat part on the cutting guide line while ensuring the difficulty of inserting an unauthorized jig or the like. Therefore, it is preferable that the through hole is formed in a long hole shape extending along the cutting guide line.

  Incidentally, the box side cutting portion 151 is formed at the same time when the front side structure 102 is molded by a mold (injection molding). That is, the mold for forming the through hole 152 of the box side cutting part 151 is provided in the mold of the front side structure 102. In this case, since the through-hole 152 of the box-side cut portion 151 is formed only in the front-side flat plate portion 130 in the front-side structure 102, the front side having the box-side cut portion 151 without causing complication of the mold structure. The structure 102 can be easily formed. That is, since the front-side structure 102 is formed in a box shape opened to one side, the direction in which the front-side structure 102 is removed after molding is naturally defined in the mold. In this case, the through-hole 152 of the box-side cutting portion 151 is formed so as to penetrate the front-side flat plate portion 130 in the thickness direction of the front-side flat plate portion 130. The penetration direction is the same direction. Therefore, the mold structure of the front side structure 102 can be prevented from becoming complicated.

  The interval between the adjacent through holes 152 is set so that the region between the adjacent through holes 152 can be easily cut by a tool such as a nipper or a cutter. Specifically, the distance between the through holes 152 is set to be smaller than the length of the through holes 152 in the longitudinal direction. Thereby, the box side cutting part 151 becomes a weak area | region in the front side flat plate part 130 compared with another site | part.

  By cutting the box-side cutting portion 151 over the entire circumference, as shown in FIGS. 11 and 12, the area partitioned by the box-side cutting portion 151 (hereinafter also referred to as a box-side removal region 153) is the front side. It becomes possible to remove from the structure 102, and it becomes possible to open the internal space of the board | substrate box 92 by removing. In this case, the box-side removal region 153 is entirely separated from the front-side structure 102, and as shown in FIG. 11, the front-side structure 102 is formed with a rectangular shape, specifically, a rectangular opening 154. . The long side portion of the opening 154 is along the long side portion of the front side flat plate portion 130, and the short side portion of the opening 154 is along the short side portion of the front side flat plate portion 130.

  By cutting the box-side cutting portion 151 and removing the box-side removal region 153, the internal space of the substrate box 92 is opened as described above. In this case, as shown in FIG. 11, the element mounting surface 97 (specifically, the CPU chip 93) of the main control board 91 is exposed. When the CPU chip 93 is exposed, the CPU chip 93 can be removed from the main control board 91.

  On the other hand, the main control board 91 cannot be taken out from the board box 92 even if the box side removal region 153 is removed. That is, the main control board 91 is fixed to the back side structure 101 using the breaking screw 117 as described above. Further, at least the long side portion of the main control board 91 is longer than the long side portion of the box side removal region 153, that is, the long side portion of the opening formed in the substrate box 92 by removing the box side removal region 153. The length dimension is set large. Therefore, as shown in FIG. 10, when the box-side removal region 153 is projected on the main control board 91 side, the peripheral edge of the main control board 91 protrudes outward from the projected area. And the area | region which protruded in the main control board 91 exists in the at least one pair of opposing both ends. Furthermore, the region of the main control board 91 that protrudes from both ends faces the front peripheral wall 131 of the front structure 102, and is fixed to the region facing the front peripheral wall 131 by the breaking screw 117. The site exists.

  With the above configuration, the main control board 91 cannot be taken out from the board box 92 even if the box-side removal region 153 is removed. As a result, in the configuration in which the box-side removal region 153 is provided in the front-side structure 102 as described above, even if it is attempted to easily obtain the genuine main control board 91 by removing the box-side removal region 153, it is difficult to do so. It becomes possible to do.

  In the configuration in which the removal of the main control board 91 is restricted, the main control board 91 is formed with a board-side cutting portion 161 as shown in FIGS. The substrate-side cutting portion 161 is configured by a large number (or a plurality of) through-holes 162 formed so as to penetrate the main control substrate 91 in the thickness direction.

  Specifically, the large number of through holes 162 are formed at equal intervals along the periphery of the main control board 91, and the large number of through holes 162 are arranged so as to surround a predetermined region of the main control board 91. That is, the substrate side cutting portion 161 is formed in an intermittent annular shape surrounding a predetermined region of the main control board 91. In other words, an intermittent annular cutting guide line is formed as the substrate-side cutting portion 161. Moreover, the board | substrate side cutting part 161 is formed in the rectangular frame shape, specifically, the rectangular frame shape. Various elements and connectors including the CPU chip 93 mounted on the main control board 91 are all included in an area partitioned by the board-side cutting unit 161.

  As shown in FIG. 8, the CPU chip 93 is installed within the area defined by the substrate-side cutting portion 161 (hereinafter referred to as “substrate-side removal area 163”), whereas the back-side structure using the breaking screw 117. The fixed portion of the main control board 91 with respect to 101 is outside the range of the board-side removal area 163. Moreover, the space | interval between the adjacent through-holes 162 in the board | substrate side cutting part 161 is set so that the area | region between the adjacent through-holes 162 can be easily cut | disconnected by tools, such as a nipper and a cutter. Incidentally, the through hole 162 of the substrate side cutting part 161 and the through hole 152 of the box side cutting part 151 have the same opening area, and further, the distance between adjacent through holes 162 in the substrate side cutting part 161 is This distance is the same as the distance between adjacent through holes 152 in the box-side cut portion 151. Therefore, the substrate side cutting part 161 can be cut using a tool for cutting the box side cutting part 151. The box side cutting unit 151 and the substrate side cutting unit 161 may be configured to require different tools.

  The area of the substrate side removal region 163 is set smaller than the area of the box side removal region 153. Further, as shown in FIG. 10, the substrate-side removal region 163 is formed so as to be included in the range of the projected region when the box-side removal region 153 is projected onto the main control substrate 91 side. . Therefore, by removing the box-side removal region 153, the entire substrate-side removal region 163, that is, the entire substrate-side cutting portion 161 is exposed. In this state, by cutting the substrate side cutting portion 161, the substrate side removal region 163 can be taken out through the opening 154 formed in the substrate box 92 by removing the box side removal region 153. In this case, since the entire substrate side cutting portion 161 is exposed through the opening 154, it is easy to perform the cutting operation of the substrate side cutting portion 161 and the removal operation of the substrate side removal region 163.

  Here, as shown in FIG. 10, the wiring pattern 164 on at least the element mounting surface 97 side of the main control board 91 is such that a part of the wiring 165 constituting the wiring pattern 164 straddles the board-side cutting portion 161. Is formed. That is, the wiring 165 is formed so as to straddle the region between the adjacent through holes 162 in the substrate-side cutting part 161. Therefore, when the substrate-side cutting portion 161 is cut to take out the substrate-side removal region 163 from the substrate box 92, the wiring pattern 164 of the main control board 91 is disconnected. As a result, even if the substrate side removal region 163 is returned to the original position after the substrate side cutting portion 161 is cut and the substrate side removal region 163 is taken out, the disconnected state of the wiring pattern 164 is maintained. The main control board 91 does not function normally. Therefore, even if an illegal act of taking out the substrate-side removal region 163 from the substrate box 92 and improperly performing the substrate-side removal region 163 and then returning it to the original position, the main control board 91 is in normal operation. It becomes possible to effectively invalidate the fraudulent behavior by not functioning properly.

  Next, a description will be given of an operation in the case where the CPU chip 93 and the main control board 91 are taken out from the board box 92 in order to perform inspection at the game hall. FIG. 13 is an explanatory diagram for explaining the operation when the CPU chip 93 and the main control board 91 are taken out from the board box 92.

  First, a case where the CPU chip 93 is inspected in the game hall will be described. First, as shown in FIG. 13A, the main control device 63 is taken out from the gaming machine main body 12. Thereafter, as shown in FIG. 13B, the box-side cutting portion 151 of the front-side structure 102 is cut to remove the box-side removal region 153. As a result, the inside of the board box 92 is opened, and the element mounting surface 97 of the main control board 91 is exposed, and the CPU chip 93 can be accessed (physical contact). Since the CPU chip 93 is not soldered to the main control board 91 as described above, the CPU chip 93 can be easily removed by pulling 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, a description will be given of the operation when the substrate-side removal region 163 of the main control substrate 91 is taken out from the substrate box 92. As shown in FIG. 13B, after the box side cutting portion 151 of the front side structure 102 is cut to remove the box side removal region 153, as shown in FIG. The substrate side cutting part 161 is cut. Thereby, the substrate-side removal region 163 of the main control board 91 can be taken out, and the inspection of the substrate-side removal region 163 in the main control board 91 can be carefully performed. In this case, since the substrate side cutting part 161 can be cut using a tool for cutting the box side cutting part 151, the work of taking out the substrate side removal region 163 can be performed relatively easily.

  Here, in the configuration in which the CPU chip 93 and the substrate-side removal region 163 can be easily removed from the substrate box 92 as described above, the CPU chip 93 or the The main control board 91 can be easily taken out for illegal purposes. On the other hand, as described above, when the CPU chip 93 is taken out from the substrate box 92, it is necessary to remove the box-side removal region 153 from the substrate box 92, and a large opening 154 is formed in the substrate box 92. It becomes. Then, if the CPU chip 93 is taken out for illegal purposes, it can be easily found.

  Further, as described above, when the main control board 91 is taken out from the board box 92, it is necessary to remove the box-side removal region 153 from the board box 92, and the board-side cutting portion 161 is cut to remove the board from the main control board 91. The side removal region 163 needs to be taken out. By removing the box side removal region 153 from the substrate box 92, a large opening 154 is formed in the substrate box 92. Further, by taking out the substrate-side removal region 163 from the main control board 91, a large opening is formed in the main control board 91. Then, if the main control board 91 has been taken out for illegal purposes, it is confirmed by checking at least one of the opening 154 formed in the board box 92 or the opening formed in the main control board 91. Can be easily discovered.

  Next, a configuration 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.

  First, a configuration for temporarily housing the CPU chip 93 in the substrate box 92 after taking out only the CPU chip 93 will be described.

  As already described, a plurality of box temporary fixing bosses 116 are integrally formed on the back side structure 101, and screw holes are formed in each box temporary fixing boss 116 (see FIG. 8). As shown in FIG. 11 and FIG. 12, box temporary fixing bosses 171 are integrally formed at the four corners of the box side removal region 153 of the substrate box 92 in a one-to-one correspondence with the box temporary fixing bosses 116. ing. The box temporary fixing boss 171 extends from the back surface of the box-side removal region 153 toward the back-side component 101 and has a screw hole. The screw hole passes through the box temporary fixing boss 171 and is opened on the front side of the box-side removal region 153.

  After removing the box-side removal region 153 and taking out the CPU chip 93, the CPU chip 93 is attached to the main control board 91 again, and the box-side removal region 153 is disposed at the original position of the substrate box 92. In this case, the box temporary fixing bosses 171 corresponding to the box side removal regions 153 overlap with the box temporary fixing bosses 116 of the back side structure 101, and the screw holes of both the bosses 116 and 171 are communicated. In this state, by screwing a break screw from the front side of the box side removal region 153, the box side cutting portion 151 is cut, but the CPU chip 93 and the main control board 91 are accommodated in the board box 92. It will be in the state.

  Here, after the CPU chip 93 is taken out of the board box 92 and carefully inspected at the game hall, the CPU chip 93 may be re-inspected by the gaming machine manufacturer. In this case, the test result of the CPU chip 93 may be abnormal, and the CPU chip 93 may be illegally exchanged. In such a case, assuming that the main control device 63 is transported to the gaming machine manufacturer with the opening 154 formed in the board box 92, the CPU chip 93 is damaged during the transport, and the CPU chip 93 is restored. There is a possibility that the inspection cannot be performed. On the other hand, by causing the box side removal region 153 to close the opening 154 of the substrate box 92 again as described above, the occurrence of breakage of the CPU chip 93 during the conveyance is suppressed.

  Further, it is assumed that an unauthorized person who has illegally exchanged the CPU chip 93 exchanges it again with a regular CPU chip 93 during the transfer of the main control device 63 to the gaming machine manufacturer. On the other hand, by screwing the box-side removal region 153 with a break screw as described above, it is difficult to remove the box-side removal region 153, and it is difficult to perform an act of trying to replace the regular CPU chip 93 again. Is possible.

  Note that as a disadvantage during the transfer of the main controller 63 to the gaming machine manufacturer, when only the former is assumed, the box-side removal region 153 need not be temporarily fixed, but a well-known removable screw. Can be used.

  Next, a configuration for temporarily housing the substrate side removal region 163 in the substrate box 92 after taking out the substrate side removal region 163 of the main control board 91 will be described.

  As already described, a plurality of temporary substrate fixing bosses 115 are integrally formed on the backside structure 101, and each substrate temporary fixing boss 115 is formed with a screw hole. As shown in FIG. 8, temporary fixing through holes 172 are formed at four corners of the substrate-side removal region 163 so as to correspond to the temporary fixing bosses 115 on a one-to-one basis.

  After removing the box-side removal region 153 and cutting the substrate-side cutting portion 161 to take out the substrate-side removal region 163, the substrate-side removal region 163 is disposed at the original position on the back-side structure 101. In this case, the temporary fixing through holes 172 corresponding to the box-side removal regions 153 communicate with the screw holes of the substrate temporary fixing boss 115 of the back side structure 101. In this state, the substrate-side removal region 163 is formed with respect to the back-side structure 101, although the substrate-side cutting portion 161 is cut by screwing the breaking screw from the element mounting surface 97 side of the substrate-side removal region 163. Fixed. Thereafter, as already described, the box side cutting area 151 is cut by temporarily fixing the box side removal region 153 through the box temporary fixing bosses 116 and 171, but the CPU chip 93 and the main control board 91 are cut. Is housed in the substrate box 92.

  Here, there is a case where the board side removal area 163 of the main control board 91 is taken out of the board box 92 and carefully inspected at the game hall, and then the board side removal area 163 is re-inspected by the gaming machine manufacturer. As this case, it is conceivable that the inspection result of the substrate-side removal region 163 is abnormal and the main control board 91 has been illegally replaced. In such a case, assuming that the main control device 63 is transported to the gaming machine manufacturer with the opening 154 formed in the substrate box 92, the substrate-side removal region 163 is damaged during the transportation and the substrate-side removal is performed. There is a possibility that the re-inspection of the area 163 cannot be performed. The same applies to the case where the substrate side removal region 163 is not fixed in the substrate box 92. On the other hand, the substrate-side removal region 163 is fixed to the back-side component 101 as described above, and the opening 154 of the substrate box 92 is closed again by the box-side removal region 153, so that the substrate-side removal region in the middle of the conveyance is obtained. The occurrence of breakage of 163 is suppressed.

  In addition, it is assumed that an unauthorized person who has illegally exchanged the main control board 91 exchanges the main control board 63 with the regular board-side removal area 163 during the transfer of the main control apparatus 63 to the gaming machine manufacturer. On the other hand, as described above, the box side removal region 153 and the substrate side removal region 163 are screwed with the breaking screws, so that it becomes difficult to remove the box side removal region 153 and the substrate side removal region 163. It is possible to make it difficult to perform an action to replace the removal area 163.

  In addition, as the inconvenience during the transfer of the main controller 63 to the gaming machine manufacturer, when only the former one is assumed, the temporary fixing of the box-side removal region 153 and the substrate-side removal region 163 does not need to be a breaking screw. What is necessary is just to perform using the detachable known screw.

  Moreover, in this Embodiment, the characteristic structure regarding the restriction | limiting of removal of both the structural bodies 101 and 102 mentioned above is provided. Hereinafter, the structure regarding the removal regulation of the back side structural body 101 and the front side structural body 102 will be described in detail. (1) Adhesive and (2) Locking mechanism are provided as restricting means for restricting the removal of the front-side structure 102 and the back-side structure 101. Therefore, each of these regulating means will be described individually.

  The adhesive is applied to the entire area of the outer wall surfaces 122 a and 123 a in the back side peripheral wall portion 121 of the back side structure 101 and the inner wall surfaces 132 a and 133 a in the front side wall portion 131 of the front side structure 102. Thereby, the back side surrounding wall part 121 and the front side surrounding wall part 131 are adhere | attached, and the removal of the back side structural body 101 and the front side structural body 102 is controlled. Since the boundary portion between the two structural members 101 and 102 is closed in this manner, even if an attempt is made to insert a fraudulent jig into the internal space of the board box 92 from the boundary portion, it is difficult to perform such an act. Yes.

  In addition, as an adhesive agent, a well-known adhesive agent can be used if the back side structural body 101 and the front 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, the locking mechanism 175 described above will be described with reference to FIGS. 14 is a partial cross-sectional view taken along line AA in FIG.

  8 and FIG. 9 again, a plurality of locking mechanisms 175 are arranged along the first peripheral wall portions 122 and 132 (two in the left and right in this embodiment), and each of them is arranged. The locking mechanism 175 includes a back side locking portion 180 provided on the back side structure 101 and a front side locking portion 190 provided on the front side structure 102 and locked to the back side locking portion 180. When the both locking portions 180 and 190 are locked, that is, by being hooked to each other, the separation of the two structural members 101 and 102 is restricted.

  As shown in FIGS. 8 and 14, the back-side locking portion 180 is formed by partitioning a part of the first back-side peripheral wall portion 122 in the back-side structure 101 with respect to the peripheral portion. More specifically, the first back side peripheral wall portion 122 is formed with a pair of cuts extending from the front edge to the root side, and the back side locking portion 180 is configured using a portion sandwiched by the cuts. ing.

  The back side locking part 180 includes an arm part 181 that stands up from the back side flat plate part 110 of the back side structure 101. The arm portion 181 has a substantially plate shape parallel to the facing wall portion 124, and the tip portion of the arm portion 181 contacts the front side flat plate portion 130 of the front side structural body 102, like the facing wall portion 124 and the first back side peripheral wall portion 122. Touching. A locking claw portion 182 that projects from the inner surface of the arm portion 181 to the inside of the back-side component 101, that is, the opposing wall portion 124 side, is integrally formed on the distal end side of the arm portion 181 (see FIG. 14). More specifically, the locking claw portion 182 protrudes into the groove portion 125 and has a back side locking surface 182a facing the bottom side of the groove portion 125, that is, the back side flat plate portion 111 side.

  In addition, although it was set as the structure which the front-end | tip of the back side latching | locking part 180 (specifically arm part 181) contact | abuts to the front side flat plate part 130, you may provide a predetermined clearance gap between both, for example, those both adjoin It is also possible. Similarly, the front end portions of the back side peripheral wall portion 121 and the opposing wall portion 124 are in contact with the front side flat plate portion 130, but a predetermined amount is provided between the front end portions of the back side peripheral wall portion 121 and the counter wall portion 124 and the front side flat plate portion 130. A gap may be provided.

  The groove portion 125 described above is fitted with the front side locking portion 190 formed integrally with the front side structure 102, and the front side locking portion 190 faces the arm portion 181 of the back side locking portion 180. It is arranged in. More specifically, the front side locking portion 190 is disposed in a region sandwiched between the plurality of insertion portions 142 (positioning means). Thereby, the inconvenience that the relative position with respect to the back side locking portion 180 is shifted is suppressed, and the occurrence of the inconvenience that the locking portions 180 and 190 are easily disconnected is preferably avoided.

  As shown in FIGS. 9 and 14, the front side locking portion 190 is opposed to the first front side peripheral wall portion 132 with a predetermined interval, and as a basic structure, an upright portion 191 that stands up from the front side flat plate portion 130 is provided. Have. The standing amount of the standing portion 191 is set slightly smaller than the standing amount of the back side locking portion 180, that is, slightly smaller than the depth dimension of the groove portion 125. For this reason, in the state where both the structural bodies 101 and 102 are combined, the tip of the upright portion 191 is in a state of facing the bottom portion of the groove portion 125 (specifically, the back side flat plate portion 110) with a predetermined interval. In addition, it is good also as a structure which makes the standing amount of the standing part 191 and the depth dimension of the groove part 125 equivalent, and the front-end | tip of the standing part 191 and the back side flat plate part 110 contact | abut.

  Further, the standing amount of the standing portion 191 (front side locking portion 190) is set smaller than the standing amount of the front side peripheral wall portion 131 (specifically, the first front side peripheral wall portion 132). For this reason, when the front side structural body 102 is placed on the floor or the like, the front side peripheral wall portion 131 comes into contact with the floor surface, and the front side locking portion 190 and the floor surface do not easily hit each other. Thereby, protection of the front side latching | locking part 190 is achieved.

  The standing portion 191 has a substantially plate shape parallel to the arm portion 181, and a locking hole portion 192 that penetrates in the plate thickness direction of the standing portion 191 and fits the locking claw portion 182 is formed on the base side thereof. Has been. A part of the inner peripheral surface of the locking hole portion 192 constitutes a front side locking surface 192a that is hooked to the locking claw portion 182 (specifically, the back side locking surface 182a), and these locking surfaces 182a, 192a. They are facing each other with a slight gap (close proximity). When the locking surfaces 182a and 192a come into contact with each other, the removal of the two structural members 101 and 102 is restricted. Further, each of the locking surfaces 182a and 192a has a planar shape perpendicular to the attaching / detaching direction of the two structural members 101 and 102. For this reason, even when each of the structural members 101 and 102 is pulled in the separating direction, the inconvenience that the locking portions 182 and 192 are displaced along the locking surfaces 182a and 192a is less likely to occur. Yes. In addition, it is good also as a structure which makes these both locking surfaces 182a and 192a contact | abut mutually in the state in which both the structures 101 and 102 were combined.

  Next, the structure which implement | achieves switching of the latching state of both latching | locking parts 180 and 190 and a latch release state is demonstrated in detail.

  As shown in FIGS. 8 and 14, the outer surface of the arm portion 181 is formed to be recessed in a step shape from the outer wall surface 122 a of the first back-side peripheral wall portion 122. Specifically, the inner surface of the arm part 181 is located on the same plane as the inner surface of the first back side peripheral wall part 122, and the thickness dimension of the arm part 181 is set smaller than the thickness dimension of the first back side peripheral wall part 122. As a result, the above-described steps are formed. For this reason, the outer wall surface 122a of the first back-side peripheral wall portion 122 is in contact with the first front-side peripheral wall portion 132 of the front-side structure 102 in almost the entire area, whereas the outer plate surface 181a of the arm portion 181 is the same. It is in a state of facing the first front side peripheral wall portion 132 with a predetermined interval (gap) therebetween. In other words, an operating space is defined between the arm portion 181 and the first front side peripheral wall portion 132 by combining both the structural members 101 and 102.

  The arm portion 181 is formed so as to facilitate bending deformation (elastic deformation) in a predetermined direction. Specifically, the thickness dimension is set to be smaller than the width dimension, that is, the length dimension in the longitudinal direction of the first back side peripheral wall portion 122 (short direction of the main control board 91). The bending deformation to the side and the 1st front side surrounding wall part 132 side is facilitated.

  As described above, a predetermined gap (that is, an operation space) is ensured between the back side locking portion 180 (specifically, the arm portion 181) and the first front side peripheral wall portion 132, and the first front side peripheral wall portion 132 side is reached. The bending deformation of the arm portion 181 is allowed within the range of the gap. That is, when the arm portion 181 is bent and deformed toward the first front side peripheral wall portion 132, the distal end portion of the arm portion 181 and the first front side peripheral wall portion 132 come into contact with each other, whereby further bending deformation is suppressed. More specifically, the distal end portion of the arm portion 181 contacts the root side of the first front peripheral wall portion 132. Thereby, it is hard to produce the problem that the 1st front side surrounding wall part 132 bends by pushing on the arm part 181. Further, by restricting the bending deformation of the arm portion 181 by the first front side peripheral wall portion 132, the occurrence of inconvenience that the arm portion 181 exceeds the elastic deformation limit to the plastic deformation region is avoided. Note that the first front side peripheral wall portion 132 is referred to as “front side” by focusing on the point that the first front side peripheral wall portion 132 restricts the bending deformation of the back side locking portion 180, that is, the displacement of the locking claw portion 182. It can also be referred to as a “regulator”.

  Similarly, the front side locking portion 190 is formed so as to be easily bent (elastically deformed) in a predetermined direction. Specifically, the plate thickness dimension of the standing part 191 is set smaller than the gap dimension between the first back side peripheral wall part 122 and the opposing wall part 124, that is, the gap dimension of the groove part 125, and is opposed to the standing part 191. A predetermined gap (that is, an operation space) is secured between the wall portion 124 and the wall portion 124.

  More specifically, the thickness dimension of the standing part 191 is set smaller than the width dimension of the standing part 191, that is, the length dimension in the longitudinal direction of the first front side peripheral wall part 132 (short direction of the main control board 91). The upright portion 191 in the longitudinal direction of the first front side peripheral wall portion 132 is difficult to be bent and deformed, and the rear side locking portion 180 side (first front side peripheral wall portion 132 side) and the opposing wall portion 124 side are arranged. The bending deformation is facilitated.

  When the front side locking portion 190 is bent and deformed toward the facing wall portion 124, further bending deformation is avoided by contacting the front side locking portion 190 and the facing wall portion 124. Specifically, the tip of the upright portion 191 contacts the base side of the opposing wall portion 124. Thereby, it is hard to produce the problem that the opposing wall part 124 bends by being pushed by the standing part 191. Further, by restricting the deformation of the front side locking portion 190 by the facing wall portion 124, the occurrence of inconvenience that the front side locking portion 190 deforms beyond the elastic deformation limit to the plastic deformation region is avoided. . Note that the opposing wall portion 124 is referred to as a “back side regulating portion” when attention is paid to the point that the deformation of the front side locking portion 190 is restricted by the facing wall portion 124, that is, the displacement of the locking hole portion 192 is restricted. It is also possible.

  Here, the relationship between the engagement margin of both the locking portions 180 and 190 (specifically, the locking surfaces 182a and 192a) and the amount of bending deformation of the both locking portions 180 and 190 will be described in detail with reference to FIGS. . FIG. 15A is a schematic view showing a state where the deformation of the back side locking portion 180 is restricted, and FIG. 15B is a schematic view showing a state where the deformation of the front side locking portion 190 is restricted. FIG. 15C is a schematic view showing a state in which the flexural deformation of both the back side locking portion 180 and the front side locking portion 190 is restricted. In addition, the dashed-two dotted line shown in FIG. 14 shows the state which each latching | locking part 180,190 is bending and deform | transforming simplified.

  As described above, in the back side locking portion 180, the back side locking portion 180 bends toward the first back side peripheral wall portion 122, whereby the back side locking surface 182a is displaced (moved) toward the first back side peripheral wall portion 122. ) Thereby, the allowance for the locking surfaces 182a and 192a is reduced. Moreover, in the front side latching | locking part 190, when the front side latching | locking part 190 bends to the opposing wall part 124 side, the front side latching surface 192a is displaced (moves) to the opposing wall part 124 side. Thereby, the allowance for the locking surfaces 182a and 192a is reduced. In the present embodiment, since the bending directions when releasing the hooks of the respective locking portions 180 and 190 are reversed, the back side locking portion 180 is hooked with respect to the front side locking portion 190 and the front side locking portion 190. The back allowance for the back side locking portion 180 is the same.

  Here, the amount of displacement of the back-side locking portion 180 (specifically, the back-side locking surface 182a) required for the release of the locked state toward the first back-side peripheral wall portion 122 and the release of the locked state are also included. The sum of the displacement amount of the front side locking portion 190 (specifically, the front side locking surface 192a) to the opposing wall portion 124 side can be regarded as a hooking amount of the both locking portions 180 and 190. Hereinafter, the engagement allowance of both the locking portions 180 and 190 is referred to as “interaction allowance X10”.

  As shown in FIG. 14, the displacement amount X11 of the back-side locking surface 182 a defined by the first back-side peripheral wall portion 122, more specifically, in a state where the tip of the back-side locking portion 180 is in contact with the first back-side peripheral wall portion 122. A displacement amount X11 of the back side locking surface 182a toward the first back side peripheral wall portion 122 (hereinafter referred to as a specified displacement amount X11) is set to be smaller than the engagement allowance X10. For this reason, even if it deform | transforms until the front-end | tip of the back side latching | locking part 180 contact | abuts to the 1st back side surrounding wall part 122, the latching state of both the latching | locking parts 180 and 190 is maintained (refer Fig.15 (a)).

  Similarly, the gap dimension X12 between the first back-side peripheral wall portion 122 and the back-side locking portion 180 is also set smaller than the hook allowance X10. As a result, for example, an intermediate portion of the back-side locking portion 180 (specifically, a portion corresponding to the back-side locking surface 182a) is pressed toward the first back-side peripheral wall portion 122 so that the amount of displacement of the back-side locking surface 182a is maximized. Even if the back side locking portion 180 is deformed, the locking state of both the locking portions 180 and 190 is maintained.

  As shown in FIG. 14, the specified displacement amount X13 of the front side locking surface 192a defined by the opposing wall portion 124, more specifically, the front side relationship in a state where the front end portion of the front side locking portion 190 is in contact with the opposing wall portion 124. A displacement amount X13 of the stop surface 192a toward the opposing wall portion 124 (hereinafter referred to as a specified displacement amount X13) is set to be smaller than the engagement allowance X10. For this reason, even if it deform | transforms until the front-end | tip of the front side latching | locking part 190 contact | abuts to the opposing wall part 124, the latching state of both the latching | locking parts 180 and 190 is maintained (refer FIG.15 (b)).

  Similarly, the gap dimension X14 between the facing wall portion 124 and the front side locking portion 190 is set smaller than the hooking allowance X10. As a result, for example, an intermediate portion of the front side locking portion 190 (specifically, a portion corresponding to the front side locking surface 192a) is pressed toward the opposing wall portion 124 so that the displacement amount of the front side locking surface 192a is maximized. Even if the locking portion 190 is deformed, the locking state of both the locking portions 180 and 190 is maintained.

  The total sum of the specified displacement amount X11 of the back side locking portion 180 and the specified displacement amount X13 of the front side locking portion 190 is set to be larger than the hanging allowance X10. For this reason, if the displacement amount of both the locking portions 180 and 190 reaches a specified value, more specifically, if the sum of the displacement amounts of both the locking portions 180 and 190 exceeds the allowance X10, the both locking portions 180 and 190 The locked state 190 is released, and the removal (separation) of the two structural members 101 and 102 is allowed (see FIG. 15C).

  Further, as shown in FIG. 14, the back side locking portion 180 has a back side guide that bends the locking portions 180 and 190 toward the side away from each other in accordance with the relative movement in the combination direction of the two components 101 and 102. A portion 183 is formed. The back side guide part 183 is continuous with the arm part 181 and the locking claw part 182 and has a planar shape that inclines toward the back of the groove part 125 from the front end side to the root side of the back side locking part 180. Further, the back side guide part 183 overlaps with a part of the front end of the front side locking part 190 in the attaching / detaching direction of the both structural members 101 and 102.

  Further, a front side guide portion 193 corresponding to the back side guide portion 183 is provided at a portion facing the back side guide portion 183 at the front end of the front side locking portion 190. Specifically, the front side guide portion 193 has a planar shape formed by chamfering the front end portion of the front side locking portion 190 and is formed to be substantially parallel to the back side guide portion 183. As a result, it is possible to suppress the support of both the guide portions 183 and 193 when they hit each other and promote smooth bending deformation. Further, the guide portions 183 and 193 can suppress the unintentional bending of the locking portions 180 and 190 and guide the normal bending deformation toward the predetermined side. . The guide portions 183 and 193 may have a curved surface.

  Next, the combination work of the two components 101 and 102 will be described with reference to FIG. 16 (a) to 16 (d) are schematic diagrams showing the flow of the combination work, and the work is performed in the order of FIG. 16 (a) → FIG. 16 (b) → FIG. 16 (c) → FIG. 16 (d). .

  As shown in FIG. 16 (a), when combining the two structural members 101, 102, the inner wall surfaces 132 a, 133 a of the front side peripheral wall portion 131 become the outer wall surfaces 122 a, 123 a of the back side peripheral wall portion 121 of the back side structural member 101. The two structural members 101 and 102 are moved relative to each other. Thereby, the relative movement direction of both the structural bodies 101 and 102 is defined.

  In the present embodiment, the amount of standing of the front side locking portion 190 from the front side flat plate portion 130 is set smaller than the amount of standing of the first front side peripheral wall portion 132 from the front side flat plate portion 130. For this reason, prior to the front side locking portion 190 being inserted into the groove portion 125, both the peripheral wall portions 121 and 131 come into contact (slide). For this reason, the shift | offset | difference of the relative position of both the latching | locking parts 180 and 190 is suppressed, and the transition to a latching state is performed, without confirming the relative position of each these latching | locking parts 180 and 190 visually. Become.

  As shown in FIG. 16A, in a state where the peripheral wall portions 121 and 131 are in contact with each other and the relative movement directions of the two structural members 101 and 102 are defined, the two structural members 101 and 102 are further moved, The front side guide part 193 of the front side locking part 190 and the back side guide part 183 of the back side locking part 180 abut. In such a state, the first front side peripheral wall portion 132 faces the tip portion of the back side locking portion 180. That is, when the bending deformation of the locking portions 180 and 190 is started by the both guide portions 183 and 193, a state in which the bending of the back-side locking portion 180 can be regulated is realized.

  When the components 101 and 102 are further moved relative to each other from the state shown in FIG. 16B, the back side guide portion 183 is pushed by the front side locking portion 190 (specifically, the front side guide portion 193), and the back side locking portion 180. However, it bends and deforms toward the first front side peripheral wall 132 side. In synchronization with this, the front side guide part 193 slides on the back side guide part 183, and the front side locking part 190 is bent and deformed toward the opposing wall part 124 side. Then, when the total amount of bending of both the locking portions 180 and 190 exceeds a predetermined amount, the locking claw portion 182 rides on the plate surface of the upright portion 191, and the combination completion position of the two structural members 101 and 102 is reached. Relative movement is allowed (see FIG. 16C).

  In this way, the locking claws 182 reach the locking hole 192 by bringing the structural members 101 and 102 closer together in a state where the movement of the both structural members 101 and 102 to the combination completion position is allowed. . Along with this, both the locking portions 180 and 190 are restored to their original state by their own elastic force, and the locking claw portion 182 is fitted into the locking hole portion 192 as shown in FIG. Almost in synchronization with this, the insertion portion 142 and the slit 141 are fitted together, and both the constituent members 101 and 102 are in a predetermined combined state. Thereby, it will be in the state by which removal of both the structural bodies 101 and 102 was controlled.

  Next, the electrical configuration of the pachinko machine 10 will be described based on the block diagram of FIG. In FIG. 17, a power supply line is indicated by a double line arrow, and a signal line is indicated by a solid line arrow.

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.

  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 CPU 222 of the sound lamp control board 221 is provided with an input / output port.

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

  Based on the combination work of the two structural bodies 101 and 102, the both locking portions 180 and 190 are shifted to the locked state. That is, work for restricting the removal (separation) of both components 101 and 102 is not required, and workability is improved.

  The combination direction of the two structural members 101 and 102 is defined by the peripheral wall portions 121 and 131 of the two structural members 101 and 102. As a result, it is possible to reduce the inconvenience that the shift to the locked state is not normally performed due to work variation or the like.

  The respective locking portions 180 and 190 forming a pair are arranged along the outer periphery of the substrate box 92. Accordingly, it is possible to suitably suppress the separation between the two structural members 101 and 102, that is, the spread of the boundary portion between the two structural members 101 and 102. By suppressing the spread of the boundary part in this way, it is possible to suitably suppress the inconvenience that an unauthorized tool or the like is inserted through the boundary part. Further, by disposing the locking portions 180 and 190 along the outer periphery of the substrate box 92, it is possible to easily avoid interference with the main control substrate 91. Therefore, coexistence with the main control board 91 is suitably realized in a limited area of the internal space of the board box 92.

  Based on the assembling work of the two structural members 101 and 102, the locking portions 180 and 190 are shifted to the locked state. That is, a predetermined combination direction is set for both components 101 and 102, and a predetermined working direction is also set for shifting the locking portions 180 and 190 to a locked state, and these directions are the same direction. It was. As a result, it is possible to integrate the assembly work of the two structural members 101 and 102 and the work of shifting the locking portions 180 and 190 to the locked state (hereinafter referred to as locking work), thereby simplifying the work. ing. Particularly in the present embodiment, since the locking portions 180 and 190 are accommodated in the internal space of the substrate box 92, the shifting of the locking portions 180 and 190 to the locked state can be performed manually. It will be difficult. If it is attempted to perform the combination operation of both the structural members 101 and 102 and the engagement operation of both the locking portions 180 and 190 in parallel, the operation is considered to be complicated. In this respect, as described above, each of the locking portions 180 and 190 can be shifted to the locked state in accordance with the combination work of the two structural members 101 and 102, so that the work is not complicated and is practically preferable. Is realized.

  In addition, if the locking operation is performed while visually confirming the locking portions 180 and 190, the shift to the locked state may be incomplete due to the variation in the combination of the two structural members 101 and 102. . In this respect, in the present embodiment, the combination of the two structural members 101 and 102 is guided by the two peripheral wall portions 121 and 131 constituting the defining means, and the positional variation associated with the combination work is less likely to occur. That is, the shift to the locked state can be realized without visually confirming the locking operation of the locking portions 180 and 190. Therefore, it is possible to make inconvenience that the shift to the locked state is not performed due to work variation or the like.

  When it is configured to include a plurality of sets of locking portions 180 and 190, an improvement in crime prevention can be expected, but work can be complicated due to the necessity of individual locking operations. In this respect, in the present embodiment, as described above, the locking operation of all the locking portions 180 and 190 depends on the combination operation of the two structural members 101 and 102, and the locking operation is performed individually. There is no need. Therefore, the combination work becomes complicated due to the increase in the number of sets of the locking portions 180 and 190 while improving the crime prevention property by adopting a configuration including a plurality of sets of locking portions 180 and 190. Can be avoided.

  As described above, the locking mechanism 175 (specifically, both locking portions 180 and 190) is accommodated in the internal space of the substrate box 92. Thereby, exposure of the locking mechanism 175 to the outside of the board box 92 can be avoided, and access (physical contact) to the locking mechanism 175 from the outside of the board box 92 can be made difficult. By making it difficult to access both the locking portions 180 and 190 in this way, it is difficult to release the locked state of the two structural members 101 and 102, and the main control board 91 and the CPU chip 93 are illegally operated. Removal and the like can be suppressed. Thereby, it can contribute to the improvement of crime prevention.

  Both the back side locking part 180 and the front side locking part 190 are bent and deformed, and the total amount of these deformations (specifically, the total amount of displacement of each locking surface 182a, 192a) exceeds the multiplying allowance X10, The locked state by both the locking portions 180 and 190 is released. In other words, even if any one of the back-side locking portion 180 and the front-side locking portion 190 is bent, the locked state cannot be released. As a result, it is possible to make an unauthorized release operation of the locked state difficult. For example, even if an unauthorized person attempts to release the locked state alone, the back side locking portion 180 is bent with one hand while the front side locking portion 190 is bent with the other hand. It is necessary to perform the separating operation of the constituent members 101 and 102, and it becomes difficult to perform all the operations alone. Therefore, it is possible to prevent unauthorized access to the main control board 91 due to the separation of the constituent members 101 and 102 as described above.

  The bending deformation of the back side locking portion 180, that is, the displacement of the back side locking surface 182 a is regulated by the first front side peripheral wall portion 132. More specifically, the maximum deflection amount of the back-side locking portion 180, that is, the maximum displacement amount of the back-side locking surface 182a is the dimension of the gap provided between the back-side locking portion 180 and the first front side peripheral wall portion 132. It is prescribed based on. For this reason, it is hard to produce the problem that only the back side latching part 180 deform | transforms excessively and a latching state is cancelled | released.

  Similarly, the maximum deflection amount of the front side locking portion 190, that is, the maximum displacement amount of the front side locking surface 192a is defined based on the gap size between the front side locking portion 190 and the opposing wall portion 124. Yes. For this reason, only the front side latching part 190 is deformed excessively, and the inconvenience that the latched state is released is less likely to occur.

  As described in detail above, since the first front side peripheral wall portion 132 and the opposing wall portion 124 are provided, even when only one of the locking portions 180 and 190 is bent and deformed, the locked state is not released. Absent. Thereby, the illegal cancellation | release of a latching state can be avoided suitably.

  When the back side locking part 180 is bent and deformed, the bending deformation is restricted by the tip of the back side locking part 180 hitting the base side of the first front side peripheral wall part 132. In this way, by suppressing the deformation of the back side locking portion 180 on the root side of the first front side peripheral wall portion 132, it is possible to suppress the first front side peripheral wall portion 132 from being bent together with the back side locking portion 180. Thereby, the function as a stopper part in the 1st front side peripheral wall part 132 can be made suitable. The same applies to the front side locking portion 190. Specifically, when the front side locking portion 190 is bent and deformed, the bending deformation is restricted by the front end portion of the front side locking portion 190 coming into contact with the base side of the opposing wall portion 124. In this manner, by suppressing the deformation of the front side locking portion 190 on the base side of the opposing wall portion 124, it is possible to suppress the opposing wall portion 124 from being bent together with the front side locking portion 190. Thereby, the excessive bending deformation of the front side latching | locking part 190 is suppressed suitably.

  Each of the locking portions 180 and 190 is disposed in a region sandwiched between the first front side peripheral wall portion 132 and the opposing wall portion 124. This makes it difficult to act to bend each of the locking portions 180 and 190 with a finger or the like. More specifically, they are arranged in a region partitioned by both constituent members 101 and 102. For this reason, exposure of each latching | locking part 180,190 is suppressed, and it is easy to avoid making unauthorized access (physical contact) with respect to these latching | locking part 180,190.

  The first front side peripheral wall portion 132 is in contact with the first back side peripheral wall portion 122 and the back side flat plate portion 110 on both sides and the root side of the back side locking portion 180. Therefore, even if an external force directed inward of the substrate box 92 is applied to the first front side peripheral wall portion 132, such external force is applied to the first back side peripheral wall portion 122 and the back side flat plate portion 110. It is distributed and is less likely to affect the back side locking portion 180.

  A first front peripheral wall 132 serving as a “stopper portion” corresponding to the back side locking portion 180 is provided on the front side structure 102 side, and an opposing wall portion serving as a “stopper portion” corresponding to the front side locking portion 190. 124 is provided on the back side structure 101 side. As a result, due to the positional deviation between the two structural members 101 and 102, the unlocking of both the locking parts 180 and 190 is realized based only on the bending deformation of the one locking part 180 and 190. Can be made difficult to occur. More specifically, if the two structural members 101 and 102 are displaced to the side where the gap between the first front peripheral wall portion 132 and the rear locking portion 180 of the front structural member 102 is widened, the front locking portion 190 is displaced. Will be displaced to the side where the allowance with the back side locking portion 180 increases. That is, the allowance between the front side locking part 190 and the back side locking part 180 increases corresponding to the widening of the gap between the back side locking part 180 and the first front side peripheral wall part 132. In addition, if the two structural members 101 and 102 are misaligned on the side where the allowance between the front side locking portion 190 and the back side locking portion 180 is reduced, the first front side peripheral wall portion 132 has a gap with the back side locking portion 180. The position will be shifted to the side where the dimensions are narrowed. That is, the gap between the back side locking part 180 and the first front side peripheral wall part 132 is narrowed corresponding to the reduction in the allowance between the back side locking part 180 and the front side locking part 190. Thereby, it is possible to suppress the balance between the engagement allowance and the gap dimension from being extremely collapsed due to the positional deviation, and to make it difficult to easily release the locked state.

  Further, in a state where both the structural bodies 101 and 102 are combined, the tip end portion of the back side locking portion 180 is in contact with the plate surface of the front side flat plate portion 130 of the front side structural body 102. In this way, by causing the back side locking portion 180 and the front side flat plate portion 130 to contact each other, it is possible to suppress bending deformation of the back side locking portion 180 in a state in which both the constituent members 101 and 102 are combined.

  The side that is bent when the back side locking portion 180 is unlocked and the side that is bent when the front side locking portion 190 is unlocked are reversed. Thereby, it is possible to easily secure the allowance for both the locking portions 180 and 190 while narrowing the operating range when the both locking portions 180 and 190 are bent and deformed. Therefore, it is possible to suppress the occurrence of inconvenience that the catching mechanism is not sufficiently performed while suppressing the expansion of the installation area of the locking mechanism 195. If the locking mechanism 195 is increased in size, it is not preferable because the operation range and the allowance can be easily secured, but the substrate box 92 is increased in size. In this regard, if it is possible to contribute to the downsizing of the locking mechanism 195 while securing the locking function as described above, it is possible to suppress the increase in the size of the board box 92, and the technical contribution becomes large. .

  In addition, the front side locking portion 190 is disposed so as to be inside the substrate box 92 relative to the back side locking portion 180. Even if a fraudulent tool or the like is inserted from the boundary portion between the two structural members 101 and 102, that is, the boundary portion between the first peripheral wall portions 122 and 132, the access to the front side locking portion 190 is not possible. It will be blocked by 180. For this reason, the act of making the front side locking part 190 bend illegally is difficult, and it is possible to suitably suppress the locked state from being illegally released.

  Furthermore, even if an unauthorized tool is inserted from the boundary portion described above, the direction of bending of the back side locking portion 180 toward the unlocking side is different from the insertion direction of the unauthorized tool. The operation of the stop portion 180 is difficult.

  Both components 101 and 102 are made of a transparent resin material. Thereby, even if it is the state which combined both structure 101 and 102, the state of both the latching | locking parts 180 and 190 is confirmed visually from the exterior of the board | substrate box 92, without removing these structure 101 and 102. be able to. This contributes to the efficiency of confirmation work.

  A box-side cutting portion 151 is formed in the substrate box 92 of the main control device 63, and the box-side cutting portion 151 is cut to remove the box-side removal region 153 from the position defining the internal space. In this case, an opening 154 that allows the removal of the CPU chip 93 storing the game control program is formed in the board box 92. And since the box side cutting part 151 is formed more easily than the case where the locked state of the back side structural body 101 and the front side structural body 102 is released, the CPU chip 93 is taken out from the board box 92 in the game hall. In the case of careful inspection, the operation can be performed relatively easily.

  Further, when the box-side cutting portion 151 is cut to open the internal space of the substrate box 92, an opening 154 is formed in the substrate box 92. If the internal space of the substrate box 92 is opened by cutting the side cutting portion 151, the discovery can be performed relatively easily.

  Furthermore, in the configuration in which the box side cutting portion 151 is provided as described above, the function for satisfactorily opening the internal space of the substrate box 92 is performed by the box side cutting portion 151. Therefore, when the back side structure 101 and the front side structure 102 are fixed, it is not necessary to consider workability when the internal space of the substrate box 92 is opened.

  That is, in the present embodiment, the back side locking portion 180 and the front side locking portion 190 are accommodated in the internal space of the substrate box 92, so that it is difficult for the locking portions 180 and 190 to release the locking. It is locked with. And the positive weak part for canceling | releasing fixation of both the structural bodies 101 and 102 by both the latching parts 180 and 190 like the conventional pachinko machine is not provided. In addition, an adhesive is applied to the boundary portion between the back-side component 101 and the front-side component 102, and both the components 101 and 102 are fixed over a wide range. Trying to insert it is difficult to do. As described above, the back-side structure 101 and the front-side structure 102 are firmly fixed, and accordingly, the act of illegally separating the back-side structure 101 and the front-side structure 102 is difficult to perform. It has become.

(Second embodiment)
In the present embodiment, the configuration relating to the attachment of the main control device and the mounting base is different from that of the first embodiment. Specifically, instead of a fastener such as a screw, a configuration equivalent to the locking mechanism 175 shown in the first embodiment is applied to the mounting base and the main controller. Therefore, the configuration will be described in detail below based on FIG. 18 and FIG. FIG. 18 is a perspective view of main controller unit 230 in the present embodiment, and FIG. 19 is a partial cross-sectional view taken along line BB in FIG. In the following description, differences from the first embodiment will be mainly described, and description of the same configuration will be basically omitted.

  The main control unit 230 has a mounting base 231 as a base member, and the main control unit 232 is mounted on the mounting base 231. The main control device 232 includes a main control board 233, and the main control board 233 is accommodated in a board box 234 as an encapsulating means made of a transparent resin material or the like.

  The main control device 232 corresponds to the main control device 63 described above, and has a control function equivalent to that of the main control device 63. The board box 234 has a back side structure 237 and a front side structure 238, and these both structures 237 and 238 are integrated so as not to be separated.

  Next, the structure of the mounting base 231 is demonstrated based on FIG. The mounting base 231 is made of a synthetic resin such as a polycarbonate resin, and almost the whole is colorless and transparent. However, the mounting base 231 may be colored, or may be opaque or translucent. The mounting base 231 is provided with a substantially flat control device mounting portion 251 facing the back side flat plate portion 241 of the back side structure 237. The control device mounting portion 251 corresponds to a main control device mounting portion for mounting the main control device 232, and is formed in a horizontally elongated substantially rectangular shape in accordance with the shape of the substrate box 234. In the control device mounting portion 251, the front side of the mounting base 231 (the side facing the back of the pachinko machine in the state of installation on the pachinko machine 10) is a control device mounting surface 251a.

  The control device mounting portion 251 is provided with a leg portion 252 extending from the plate surface opposite to the control device mounting surface 251a (the back side of the mounting base 231) to the back surface of the game board 33. The leg portions 252 are formed along the edges on both sides in the longitudinal direction of the control device mounting portion 251, and one leg portion 252 is provided with a pair of upper and lower bearing portions 253. These bearing portions 253 are pivotally supported by the support shaft portion on the mounting counterpart side (game board 33 side) of the main mounting base 231, so that the mounting base 231 (main controller unit 230) rotates with respect to the game board 33. It is designed to be movable and cantilevered.

  In addition, the other leg portion 252 is provided with a plurality (specifically, two) of attachment portions 254 for attaching fasteners. The main mounting base 231 (main controller unit 230) is fastened to the game board by the fasteners attached to these mounting portions 254.

  In addition, a spacer member 255 is provided between the mounting base 231 and the game board 33. The spacer member 255 is fixed to the mounting base 231 by the fixing tool such as the above-described breaking screw. The spacer member 255 prevents unauthorized tools and the like from entering the space behind the mounting base 231. Further, attachment of an illegal board or the like in the space behind the control device mounting portion 251 is also prevented.

  The spacer member 255 will be described in detail. The spacer member 255 has a hollow block shape as a whole, and is formed of a colorless and transparent synthetic resin material. The projected area of the spacer member 255 substantially matches the area of the control device mounting portion 251 of the mounting base 231. The thickness dimension of the spacer member 255 is set to be substantially the same as the length dimension of the leg portion 252 of the mounting base 231 or slightly smaller than the length dimension of the leg portion 252. Therefore, the spacer member 255 has substantially the same occupied volume as the back space of the control device mounting portion 251 of the mounting base 231, and is just fit in the back space.

  A large number of lattice-like ribs 256 are formed on the spacer member 255, and the large number of ribs 256 prevents a relatively large one from being formed as a space-like lump. That is, the space is subdivided. Also, by providing a large number of ribs 256, the weight of the spacer member 255 is reduced while obtaining a desired effect such as subdivision of the space.

  A pair of first upright portions 261 standing on the control device mounting surface 251a side and facing the main control device 232 from both sides in the longitudinal direction of the control device mounting portion 251 at each peripheral edge of the control device mounting portion 251; Similarly, a pair of second upright portions 262 are formed that stand on the control device mounting surface 251a side and face the main control device 232 from both sides in the short direction of the control device mounting portion 251. Each of the upright portions 261 and 262 corresponds to the first front side peripheral wall portion 242 and the second front side peripheral wall portion 243 of the front side structure 238, and is provided outside the inner surface 261 a of the first upright portion 261 and the first front side peripheral wall portion 242. While the wall surface 242a is in contact, the inner surface 253a of the second upright portion 262 and the outer wall surface 243a of the second front side peripheral wall portion 243 are in contact. Each of the standing portions 261 and 262 and the front peripheral wall portions 242 and 243 has a function as a defining portion that defines the mounting direction when the main control device 232 is mounted on the mounting base 231.

  In addition, a narrow recess 263 extending along the first upright portion 261 is formed at the base end portion of the first upright portion 261 in the control device mounting portion 251. The front-end | tip part of the 1st front side surrounding wall part 242 in the front side structural body 238 protrudes in the mounting base 231 side rather than the back side flat plate part 241, and when this protruded part fits into the recessed part 263, both structure 237,238 The access to the internal space of the room is more suitably suppressed. Hereinafter, the protruding portion of the first front peripheral wall portion 242 described above is referred to as a “projecting portion 245” for convenience.

  Here, the restricting means 270 for restricting removal (separation) between the mounting base 231 and the main control device 232 and the configuration related thereto will be described in detail.

  As shown in FIGS. 18B and 19, the recess 263 includes a plurality of expansion regions 263 a in which the gap dimension (width dimension) in the longitudinal direction of the control device mounting portion 251 is expanded as compared with other portions. Yes. The restricting means 270 is accommodated in the extended region 263a (see FIG. 19).

  As shown in FIG. 19, a mounting base side locking portion 271 constituting the restricting means 270 is integrally formed with the bottom portion 264 of the concave portion 263. The mounting base side locking portion 271 has the same configuration as that of the back side locking portion 180 in the first embodiment, that is, an arm portion 272 facing the protruding portion 245 with a predetermined gap, and the arm portion 272. A locking claw portion 273 that is formed on the distal end side and protrudes on the opposite side is provided. The latching claw portion 273 is displaced to the protruding portion 245 side as the arm portion 272 is bent and deformed (elastically deformed) toward the protruding portion 245, and the deformation of the arm portion 272 comes into contact with the protruding portion 245. Therefore, the displacement of the locking claw portion 273 is suppressed. The mounting base side locking portion 271 is formed with a mounting base side guide portion 274 similar to the back side locking portion 180. The mounting base side guide portion 274 is similar to the back side guide portion 183 described above. The detailed description is omitted because of the configuration.

  On the other hand, the main control device 232 is provided with a structural body side locking portion 281 that constitutes the regulating means 270 and is locked to the mounting base side locking portion 271. Specifically, the structural body side locking portion 281 protrudes from the back side flat plate portion 241 toward the mounting base 231 and is accommodated in the above-described recess 263. Specifically, it is arranged in the concave portion 263 on the same side as the side on which the locking claw portion 273 of the mounting base side locking portion 271 is provided. That is, the mounting base side locking portion 271 is arranged between the component side locking portion 281 and the protruding portion 245 of the first front side peripheral wall portion 242.

  The structural body side locking portion 281 is formed integrally with the back side flat plate portion 241 and has the same configuration as the front side locking portion 190 in the first embodiment. That is, a plate-like standing portion 282 that stands up from the back side flat plate portion 241 and faces the arm portion 272, and a locking hole portion 283 that is formed in the standing portion 282 and into which the locking claw portion 273 is fitted. Further, the upright portion 282 faces the vertical wall portion 265 constituting the concave portion 263 with a predetermined gap therebetween.

  As the upright portion 282 is bent and deformed (elastically deformed) toward the vertical wall portion 265, the locking hole portion 283 is displaced toward the vertical wall portion 265, and the deformation of the upright portion 282 contacts the vertical wall portion 265. By being regulated based on this, the displacement of the locking hole 283 is suppressed. Further, the structural body side locking portion 281 is formed with a structural body side guide portion 284 similar to the front side locking portion 190, but the structural body side guide portion 284 has the same configuration as the front side guide portion 193. Therefore, detailed description is omitted.

  When the main control device 232 is mounted on the mounting base 231, the front peripheral wall portions 242 and 243 (specifically, the outer wall surfaces 242 a and 243 a) of the main control device 232 are placed along the upright portions 261 and 262 of the mounting base 231. When the main controller 232 is pushed into the controller mounting surface 251a side in the state, the mounting direction is defined. Along with such a pushing operation, the protrusion 245 of the main controller 232 is inserted into the recess 263 of the mounting base 231. The protruding amount of the protruding portion 245 from the back side flat plate portion 241 is set sufficiently larger than the rising amount of the upright portion 282 from the back side flat plate portion 241, and the guide portions 274 and 284 of both the locking portions 271 and 281 are arranged. Before the contact, the projecting portion 245 is inserted into the recess 263, and the bending deformation of the arm portion 272 can be regulated.

In this state, when the main controller 232 is further pushed in, the arm portion 272 and the upright portion 282 are bent and deformed, and the both locking portions 271 and 281 are displaced so as to be separated from each other. Then, almost in synchronization with the main control device 232 reaching a predetermined mounting completion position, that is, the back side flat plate portion 241 of the main control device 232 abuts against the control device mounting surface 251a,
The arm part 272 and the upright part 282 return to the original state, and the locking surfaces 271a and 281a of the locking parts 271 and 281 are hooked. Thereby, both the latching | locking parts 271 and 281 transfer to a latching state, and will be in the state in which removal from the mounting base 231 of the main-control apparatus 232 was controlled.

  In addition, the mutual allowance of each latching surface 271a and 281a, the clearance dimension of the mounting base side latching | locking part 271 and the protrusion part 245, and the clearance gap dimension of the structure side latching | locking part 281 and the vertical wall part 265 are mutually. Since the relationship is the same as that of the first embodiment, detailed description is omitted.

  According to the second embodiment described above in detail, like the first embodiment described above, unauthorized removal of the main control board 233 can be suitably suppressed.

  It is possible to make it difficult to remove the main control device 232 while facilitating the mounting operation of the main control device 232 to the mounting base 231. Specifically, the locking portions 271 and 281 are shifted to the locked state by an operation of pushing the main control device 232 to the mounting completion position. For this reason, it is not necessary to perform the arrangement | positioning operation | work of the main controller 232, and a latching operation | work separately, and it can contribute to simplification of an operation | work. In order to release the locked state, it is necessary to bend both the locking portions 271 and 281. Thus, since it is difficult to bend both the latching | locking parts 271,281, it can suppress that the main control apparatus 232 is removed illegally.

  The locking portions 271 and 281 are arranged at positions sandwiched between the mounting base 231 and the main control device 232. In other words, the locking portions 271 and 281 are covered with the mounting base 231 and the main control device 232. Accordingly, access to the locking portions 271 and 281 can be prevented by the main control device 232 and the mounting base 231. Thus, by covering the locking portions 271 and 281 with the main controller 232 and the mounting base 231, without providing a cover member or the like that covers the locking portions 271 and 281, that is, while avoiding complication of the configuration. Unauthorized access can be suppressed and a practically preferable configuration can be realized.

  More specifically, when the main control device 232 is mounted on the mounting base 231, both the locking portions 271 and 281 are stored in the recess 263. Specifically, by combining the main control device 232 and the mounting base 231, the open portion of the concave portion 263 in the mounting base 231 is blocked by the main control device 232, and thus formed in the concave portion 263. Both locking portions 271 and 281 are accommodated in the closed space. This makes it difficult to access both the locking portions 271 and 281 from the outside of the main controller unit 230, and can prevent the locking states of the locking portions 271 and 281 from being released. .

  Further, the mounting base side locking portion 271 is disposed between the protruding portion 245 of the first front side peripheral wall portion 242 and the boundary portion of the first upright portion 261 and the component side locking portion 281. For this reason, even if an unauthorized tool or the like is inserted through the boundary portion, the mounting base side locking portion 271 can prevent access to the component side locking portion 281. Thereby, it is possible to prevent an unauthorized operation from being performed in both the locking portions 271 and 281.

  When the main control device 232 is mounted, the mounting direction is defined by placing the peripheral wall portions 242 and 243 of the main control device 232 along the upright portions 261 and 262 of the mounting base. Thereby, it is possible to carry out the mounting operation without visually confirming the relative positions of the both locking portions 271, 281 and the like, which can contribute to ensuring workability.

  Based on the movement of the main control device 232 toward the specified mounting direction described above, the guide portions 274 and 285 cause the locking portions 271 and 281 to bend. Thereby, the transition to the locked state can be realized without directly touching the locking portions 271 and 281. Therefore, the storage of the respective locking portions 271 and 281 as described above can be suitably realized, which can contribute to improvement in workability and improvement in crime prevention.

  In addition to the substrate box 234, the mounting base 231 and the spacer member 255 are also formed of a transparent material. For this reason, it is possible to check the locking state of the locking portions 271 and 281 while the main controller 232 is mounted on the mounting base 231. Furthermore, each of the locking portions 271 and 281 is arranged on both sides of the main control board 233 in the front view of the main control apparatus 232, that is, at a position avoiding overlapping with the main control board 233 in the front-rear direction. Yes. For this reason, the visual recognition of both the locking portions 271 and 281 is not hindered by the main control board 233. Therefore, the locking portions 271 and 281 (that is, the locked state) can be confirmed without rotating the main controller unit 230, and further improvement in workability can be expected.

  As described above in detail, the main controller 232 (main control board 233) is taken away or illegally replaced by making it difficult to remove the main controller 232 from the mounting base 231. It can avoid suitably and can contribute to the improvement of crime prevention.

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

  (1) In the first embodiment, the back side locking portion 180 of the back side structural body 101 has the locking claw portion 182, and the front side locking portion 190 of the front side structural body 102 has the locking hole 192. However, this can be changed as follows. For example, the back side locking part 180 may have a locking hole part, and the front side locking part 190 may have a locking claw part. Moreover, it is good also as a structure which both the latching | locking parts 180 and 190 each have a latching claw part, and these latching claw parts mutually hook.

  Similarly, in the second embodiment, the mounting base side locking portion 271 may have a locking hole portion, and the component side locking portion 281 may have a locking claw portion.

  (2) In the first embodiment, the back-side locking portion 180 and the front-side locking portion 190 are bent and deformed in opposite directions, whereby the locking state of both the locking portions 180 and 190 is released. However, the bending side of each of the locking portions 180 and 190 is not limited to the “reverse side”.

  Hereinafter, a modification will be described with reference to FIG. FIG. 20A is a schematic view showing the back side locking portion and the front side locking portion, and FIGS. 20B to 20D are viewed from the combination direction of both components (front of the main controller). It is explanatory drawing which shows the latching state of both the latching | locking parts (viewed from the side), FIG.20 (e) is the both latching parts seen from the combination direction of both components (viewed from the front side of the main controller) It is explanatory drawing which shows the latching release state. In addition, since it has the structure substantially the same as the back side latching | locking part 180 mentioned above regarding the back side latching | locking part, detailed description is abbreviate | omitted.

  As shown in FIG. 20A, the front side locking portion 311 of the front side structure 300 is located on the side of the back side locking portion 180 in the groove 125 (specifically, on the second back side peripheral wall portion 123 side of the back side structure 101). The arm part 312 which stands up toward the back side flat plate part 110 side of the back side structural body 101 from the front side flat plate part 310 is provided. The arm portion 312 has a plate shape, and the plate surface faces the longitudinal direction of the first front peripheral wall portion 313, that is, the short direction of the main control board 91. As described above, the arm portion 312 has a plate shape, which facilitates bending deformation toward the second back side peripheral wall portion 123 side. Further, the width dimension of the arm portion 312 is set to be approximately equal to the distance between the first back side peripheral wall portion 122 and the opposing wall portion 124 in the groove portion 125, and to the first back side peripheral wall portion 122 and the opposing wall portion 124 side. The bending deformation of is suppressed.

  A front side locking claw portion 314 that is hooked on a locking claw portion 182 of the back side locking portion 180 (hereinafter referred to as a back side locking claw portion 182 for convenience) is formed on the distal end side of the arm portion 312. More specifically, the front side locking claw portion 314 protrudes from the plate surface on the side facing the back side locking portion 180 in the arm portion 312. The front side locking claw portion 314 has a front side locking surface 314a that faces the back side locking surface 182a of the back side locking claw portion 182. When the both locking surfaces 182a and 314a are hooked, the back side structure The removal (separation) of 101 and the front side structure 300 is regulated.

  When the arm portion 312 of the front side locking portion 311 is bent and deformed toward the second back side peripheral wall portion 123 side of the back side structure 101, the front side locking surface 314a is displaced to the side away from the back side locking surface 182a, and both locking The allowance for the surfaces 182a and 314a is reduced.

  Further, a stopper portion 317 for restricting the deformation of the front side locking portion 311 is formed on the side opposite to the side where the front side locking claw portion 314 is formed in the arm portion 312. The stopper portion 317 is integrally formed with the opposing wall portion 124 and has a plate shape that stands up from the opposing wall portion 124. The stopper portion 317 is opposed to the arm portion 312 at a predetermined interval. When the front side locking portion 311 is bent, the end portion of the stopper portion 317 comes into contact with the plate surface of the arm portion 312, so Bending deformation is regulated.

  Here, with reference to FIG. 20B to FIG. 20D, the engagement allowance between the both locking surfaces 182 a and 314 a will be described. As shown in FIG. 20B, in the locked state of both locking portions 180 and 311, the half on the front side locking portion 311 side in the back side locking surface 182 a and the back side locking portion in the front side locking surface 314 a. The half on the 180 side overlaps with each other in the attaching / detaching direction of the front structure 300. The back-side locking surface 182a has a substantially rectangular shape as a whole, and a back-side notched edge 318 is formed at the corner on the front-side locking portion 311 side and the side opposite to the side on which it is bent. On the other hand, the front side locking surface 314a has a substantially rectangular shape as a whole, and a back side notch edge portion 318 and a corner on the back side locking portion 180 side and opposite to the bending side thereof are provided. Parallel front-side notch edges 319 are formed.

  As shown in FIG. 20 (c), when the back side locking portion 180 is bent and deformed and the back side locking surface 182a is displaced toward the first front peripheral wall portion 313, the amount of engagement between the locking surfaces 182a and 314a is reduced. However, a part of both the locking surfaces 182a and 314a is maintained in an overlapping state. Specifically, a part of the back-side notch edge 318 is maintained in a state where it overlaps with the front-side locking surface 314a. For this reason, the latching state of both latching | locking parts 180 and 311 will be maintained suitably.

  In addition, the displacement amount of the back side locking surface 182a in this different example, that is, the specified displacement amount and the maximum displacement amount defined by the first front side peripheral wall portion 313 are substantially equal. FIG. 20 (c) shows the relative relationship when the maximum displacement occurs, but the same relative relationship is maintained even when the prescribed displacement occurs. That is, a part of the back side notch edge portion 318 is maintained in a state where it overlaps the front side locking surface 314a.

  In this state, the remaining allowance, more specifically, the allowance in the bending direction of the front side locking portion 311 is smaller than the specified displacement amount and the maximum displacement amount of the front side locking surface 314a. .

  As shown in FIG. 20 (d), when the front side locking portion 311 is bent and deformed and the front side locking surface 314a is displaced toward the stopper portion 317, the engagement margin between the both locking surfaces 182a and 314a decreases. However, a part of both the locking surfaces 182a and 314a is maintained in an overlapping state. Specifically, a part of the front-side notch edge 319 is maintained in a state where it overlaps the back-side locking surface 182a. For this reason, the latching state of both the latching | locking parts 158 and 231 will be maintained suitably.

  In addition, the displacement amount of the front side locking surface 314a in this different example, that is, the specified displacement amount and the maximum displacement amount defined by the stopper portion 317 are substantially equal. FIG. 20 (c) shows the relative relationship when the maximum displacement occurs, but the same relative relationship is maintained even when the prescribed displacement occurs. That is, a part of the front-side notch edge 319 is maintained in a state where it overlaps the back-side locking surface 182a.

  In such a state where the allowance is reduced, the remaining allowance, specifically, the allowance in the bending direction of the back side locking portion 180, is smaller than the specified displacement amount and the maximum displacement amount of the back side locking surface 182a.

  Here, when the front side locking surface 314a is displaced from the state of FIG. 20 (c), or when the back side locking surface 182a is displaced from the state of FIG. 20 (d), as shown in FIG. The engagement allowance of both the locking surfaces 182a and 314a is zero. That is, when the back side locking surface 182a is displaced toward the first front side peripheral wall portion 313 and the front side locking surface 314a is displaced toward the stopper portion 317, the hooked state of both the locking surfaces 182a and 314a is Canceled.

  The front side locking portion 311 is formed with a front side guide portion 321 similar to the back side guide portion 183 shown in the above embodiment. With the relative movement in the combination direction of the two structural members 101 and 300, the back side guide portion 183 and the front side guide portion 321 come into contact with each other, and the bending deformation of the respective locking portions 190 and 311 is realized.

  Incidentally, the modification described in detail above can also be applied to the second embodiment.

  (3) In the first embodiment, the locking portions 180 and 190 themselves are flexibly deformed (elastically deformed) to switch between the locked state and the unlocked state. It may be changed as follows. That is, the locking portions 180 and 190 are movably provided, and the locking states 180 and 190 are engaged with each other based on the fact that the locking portions 180 and 190 move while bending deformation of a separately provided member (biasing member). Switching to the stop release state may be performed.

  Hereinafter, a specific example will be described with reference to FIG. The back side locking portion 331 is provided separately from the back side structure 101. A shaft portion 332 extending in the same direction as the longitudinal direction of the groove portion 125 (that is, the short direction of the main control board 91) is integrally formed at the end portion of the back side locking portion 331 on the back side flat plate portion 110 side. A bearing hole portion 333 into which the shaft portion 332 is fitted is formed in the first back side peripheral wall portion 122 of the back side structure 101, and the shaft portion 332 is inserted into the bearing hole portion 333. Thereby, the back side latching | locking part 331 is the state supported by the back side structure 101 so that rotation was possible.

  A leaf spring 335 is provided between the back side locking portion 331 and the first front side peripheral wall portion 132 of the front side structure 102. The leaf spring 335 has a main body 336 parallel to the first front peripheral wall 132, and the main body 336 is bonded to the first front peripheral wall 132. As a result, the leaf spring 335 is integrated with the front side structure 102.

  The leaf spring 335 is formed with a bent portion 337 protruding toward the back side locking portion 331, and the tip of the bent portion 337 contacts the back side locking portion 331 (specifically, the arm portion 338). ing. The protruding amount of the bent part 337 from the main body part 336 is set to be slightly larger than the gap dimension between the back side locking part 331 and the first front side peripheral wall part 132. Thereby, in the state where the bent portion 337 is in contact with the back side locking portion 331, the back side locking portion 331 is biased toward the front side locking portion 190 side.

  When the two structural members 101 and 102 are combined, the front side locking portion 190 and the back side locking portion 331 come into contact with each other, whereby the back side locking portion 331 rotates to the first front side peripheral wall portion 132 side. In such a case, the bent portion 337 is folded, and the back side locking portion 331 is urged toward the opposing wall portion 124 side. Along with the relative movement in the combination direction of the two structural members 101, 102, when the locking claw portion 339 of the back side locking portion 331 reaches a position where it can be fitted into the locking hole portion 192 of the front side locking portion 190, The back side locking portion 331 rotates by the urging force of the leaf spring 335 and returns to the original position. Thereby, the latching claw part 339 fits in the latching hole part 192, and both are in a latched state.

  As described in detail above, the leaf spring 335 is elastically deformed, so that switching between the locked state and the unlocked state can be realized. A coil spring or the like can be used instead of the plate spring 335.

  (4) In the first embodiment described above, the opposing wall portion 124 as a “first stopper portion” that restricts the bending deformation of the front side locking portion 190 is provided on the back side structural body 101 side, and the bending deformation of the back side locking portion 180 is performed. The first front side peripheral wall portion 132 as the “second stopper portion” for regulating the front side structure 102 is provided on the front side structure 102 side, but this is changed, and the “first stopper portion” is provided on the front side structure 102 side. The “two stopper portions” may be provided on the back side structure 101 side.

  For example, as shown in FIG. 21B, a front side stopper portion 351 that restricts the deformation of the front side locking portion 190 is integrally formed on the front side structure 102, and the deformation of the back side locking portion 180 is deformed on the back side structure 101. It is preferable to integrally form a back side stopper portion 352 that regulates the above. More specifically, the front side stopper portion 351 is formed to face the front side locking portion 190 with a predetermined gap, and the back side stopper portion 352 is spaced from the back side locking portion 180 with a predetermined gap. It is good to form so that it may confront.

  Similarly, in the second embodiment, a “first stopper portion” for restricting the deformation of the mounting base side locking portion 271 is provided on the mounting base 231 side, and the deformation of the structural body side locking portion 281 is restricted. A “second stopper portion” may be provided on the substrate box 234 side.

  (5) In the first embodiment described above, a part of the first back side peripheral wall portion 122 of the back side structure 101 is configured by the back side locking portion 180, but the present invention is not limited to this. For example, the back side locking part 180 can be formed separately and independently from the first back side peripheral wall part 122.

  (6) In the first embodiment, the front ends of the locking portions 180 and 190 hit the opposing wall portion 124 as the “first stopper portion” and the first front side peripheral wall portion 132 as the “second stopper portion”. The bending of the locking portions 180 and 190 is regulated by the above-mentioned, but this is changed, and the portions other than the tip portions of the locking portions 180 and 190 are bent by hitting the opposing wall portion 124 and the first front peripheral wall portion 132. You may regulate.

  Moreover, although the opposing wall part 124 and the 1st front side peripheral wall part 132 were each made into plate shape, it is not limited to this. In other words, the “first stopper portion” and the “second stopper portion” do not have to be plate-shaped as long as the bending deformation of the locking portions 180 and 190 can be restricted. For example, the “first stopper portion” and the “second stopper portion” can be configured by protrusions or the like that protrude from the back-side structure 101 or the front-side structure 102. The “first stopper portion” and the “second stopper portion” do not necessarily have to be integrally formed with the back side structure body 101 and the front side structure body 102, and members formed separately are used as the back side structure body 101 and the front side structure body. You may attach to 102.

  Incidentally, in the second embodiment as well, the “first stopper portion” and the “second stopper portion” can be configured by protrusions or the like that protrude from the back-side structure 101 or the front-side structure 102. .

  (7) In the first embodiment, the back side locking portion 180 is provided with the back side guide portion 183 and the front side locking portion 190 is provided with the front side guide portion 193.

  (8) In the first embodiment, the both locking portions 180 and 190 are hooked in the groove 125. However, the both locking portions 180 and 190 can be hooked outside the groove 125. is there.

  In the second embodiment, both the locking portions 271 and 281 are hooked in the recess 263. However, the both locking portions 271 and 281 can be hooked outside the recess 263.

  (9) In each of the above embodiments, the engagement can be released when the sum of the displacement amounts of the engagement surfaces 182a and 192a of the engagement portions 180 and 190 reaches a specified value. It is good also as a structure which can cancel | release latching, when the displacement amount of surface 182a, 192a becomes the maximum.

  (10) In the first embodiment described above, when the two structural members 101 and 102 are combined, the bending deformation is generated in synchronism with the locking portions 180 and 190. However, the timing at which the bending deformation occurs is always synchronized. There is no need. That is, when both the locking portions 180 and 190 come into contact with each other, the one locking portion is first bent and deformed to a restricted limit, and after the bending deformation is suppressed, It is good also as a structure by which the other latching part bends and deforms by pushing.

  In addition, the same change is possible also about the generation | occurrence | production timing of the bending deformation of the mounting base side latching | locking part 271 and the structure side latching | locking part 281 in 2nd Example.

  (11) In each of the above embodiments, the front side locking portion 190 is disposed between the insertion portions 142 as positioning means. However, it is also possible to dispose them in a range other than between the insertion portions 142.

  Next, the configuration of the main control device 63 will be described in detail with reference to FIGS. 29 is a perspective view of the main controller 63, FIG. 30 is a front view of the main controller 63, and FIG. 31 is an exploded perspective view of the main controller 63.

  As shown in FIG. 31, the main control device 63 includes a main control board 91 and a board box 92, and the main control board 91 is accommodated in the internal space of the board box 92.

  The main control board 91 includes a CPU that performs main control, a ROM that stores a game program, a RAM that stores necessary data according to the progress of the game, and the like. In the present embodiment, the CPU, ROM, and RAM are integrated into one chip on the CPU chip 93. Although not described in detail, an input / output driver IC chip 94 and a latch IC chip 95 are mounted. Although not shown, the main control board 91 is mounted with various elements such as capacitors and resistors and a plurality of connectors.

  In the main control board 91, various elements such as the CPU chip 93 are all mounted on the same plate surface and soldered on the opposite plate surface. That is, in the main control board 91, one plate surface is an element mounting surface 96 and the other plate surface is a solder surface. The solder surface is a surface on which soldering portions of various elements mounted on the element mounting surface 96 are provided, but a circuit pattern may be formed on the solder surface.

  The board box 92 includes a front side structure (box cover) 101 and a back side structure (box base) 102 as a plurality of box structures. The front-side structure 101 and the back-side structure 102 are formed of a material having transparency so that the element mounting surface 96 and the solder surface of the main control board 91 accommodated in the board box 92 can be seen from the outside of the board box 92. Has been. Specifically, it is formed of a colorless and transparent polycarbonate resin, but the forming material is not limited to this and may be an acrylic resin or the like.

  By combining the front side structure 101 and the back side structure 102, as shown in FIGS. 29 and 30, the substrate box 92 is formed in a square box shape (substantially rectangular parallelepiped shape) and has a predetermined internal space. ing. Specifically, as shown in FIG. 31, the front side structure 101 is formed so as to swell to the one side from the front side peripheral part 103 that defines the peripheral edge of the front side structure 101 and the front side peripheral part 103. The bulging portion 104 is integrally formed. By these front side peripheral edge portion 103 and the bulging portion 104, the front side structure 101 has a substantially rectangular parallelepiped shape opened to the opposite side of the bulging portion 104 from the bulging side.

  The main control board 91 is screwed to the front side structure 101 from the back side (fixed in a detachable state). The screws of the main control board 91 to the front side structure 101 are fixed from the solder surface side of the main control board 91, and various elements mounted on the element mounting surface 96 of the main control board 91 are main control. It is accommodated in a region between the substrate 91 and the front side structure 101.

  The back side structure 102 is fixed to the front side structure 101 in which the main control board 91 is integrated. As shown in FIG. 31, the back-side structure 102 is formed in a substantially plate shape having a quadrangular shape, specifically, a rectangular shape when viewed from the front. The flat surface portion 105 and the flat surface portion are formed in a flat shape. A back-side peripheral edge 106 formed so as to surround the periphery of 105 is integrally formed.

  By fixing the back side structure 102 from the back side to the front side structure 101, the front side peripheral part 103 of the front side structure 101 and the back side peripheral part 106 of the back side structure 102 overlap, and the back side of the bulging part 104 The open portion to the side is closed by the flat portion 105 of the back side structure 102. In this case, the solder surface of the main control board 91 is covered with the back side structure 102. That is, the entire element mounting surface 96 of the main control board 91 is opposed to the front side structure 101, and the entire solder surface of the main control board 91 is opposed to the back side structure 102. As shown in FIG. 27, the main controller 63 having the above-described configuration is mounted such that the surface of the front-side component 101 faces the back of the pachinko machine 10.

  Next, the structure regarding fixation with the front side structure 101 and the back side structure 102 is demonstrated in detail. The configuration relating to the fixation of the two structural members 101 and 102 includes a restricting means for restricting the mutual displacement of the two structural members 101 and 102 only in a specific restricting direction, and both preventing the misalignment in the restricting direction. Fixing means for fixing the constituent members 101 and 102 to each other.

  First, the regulating means will be described in detail. In the following description of the regulating means, not only FIG. 31 but also FIG. 32 will be referred to as appropriate. FIG. 32A is an enlarged side view showing a part of the main control device 63, and FIG. 32B is a cross-sectional view taken along the line AA of FIG.

  As shown in FIG. 31, a hook portion (an engaging portion or a front side regulating portion) 111 is integrally formed on the front side structure 101 as a regulating means. A plurality of hook portions 111 are provided, and these hook portions 111 are along the direction in which the long side portions extend in each of the opposing long side portions (specifically, the upper edge portion and the lower edge portion) of the front side peripheral edge portion 103. Are formed at regular intervals. In this case, six hook portions 111 are formed on each of the upper and lower portions, but the number thereof is arbitrary as long as it is plural. The hook portions 111 are all formed to have the same shape, and are all formed to the same size.

  The shape of the hook part 111 will be described in detail. The front side peripheral portion 103 of the front side structure 101 includes a frame portion 112 formed in a rectangular frame shape along the front side peripheral portion 103. The frame portion 112 is formed by standing from the base portion 110 continuing to the bulging portion 104 at the front side peripheral edge portion 103 toward the back side structure 102. In this case, the projecting dimension (height dimension) of the frame part 112 from the base part 110 is the same as the thickness dimension of the main control board 91. The projecting dimension of the frame part 112 from the base part 110 may be larger than the thickness dimension of the main control board 91.

  A plurality of hook portions 111 are formed on an upper frame portion (one frame portion) 113 constituting one long side portion in the frame portion 112, and one long side is located at a position facing the upper frame portion 113. A plurality of hook portions 111 are also formed in a lower frame portion (another frame portion) 114 constituting the portion. In this case, the inner surface of each hook portion 111 is located on the same plane as the inner surface of the forming frame portion 112, and the outer surface of each hook portion 111 is the outer surface of the forming frame portion 112. It is located on the same plane as this surface.

  The hook portion 111 is formed with the frame portion 112 as a base end, and is formed by being bent at an intermediate position so that the free end side extends toward one short side of the front side structure 101, specifically, toward the right edge. Has been. That is, the hook portion 111 is formed by integrally forming a standing portion 115 that rises from the frame portion 112 toward the back-side component 102 and an extending portion 116 that extends from the standing portion 115 toward the side edge of the front-side component 101. .

  The extending portion 116 is separated from the frame portion 112 by the height dimension of the upright portion 115, and a locking groove 117 is formed between the extending portion 116 and the frame portion 112. The locking groove 117 is formed along the extended portion 116 and is opened on the free end side of the extended portion 116.

  A locking receptacle (back side regulating portion) 121 is integrally formed on the back side structure 102 so as to correspond to the hook portion 111. The shape of the latch receiver 121 will be described in detail. A series of upper peripheral wall portions 122 are integrally formed along the entire side portion of the back side peripheral portion 106 of the back side structure 102 on the side portion corresponding to the upper frame portion 113 of the front side structure 101. A series of lower peripheral wall portions 123 are integrally formed on the side portion corresponding to the lower frame portion 114 of the structural body 101 along the entire side portion. The upper peripheral wall portion 122 and the lower peripheral wall portion 123 are erected toward the front side structure 101. Each of the upper peripheral wall portion 122 and the lower peripheral wall portion 123 constitutes a peripheral surface (upper surface and lower surface) of the back-side component 102 and also constitutes a peripheral surface (upper surface and lower surface) of the substrate box 92.

  The back side peripheral portion 106 includes an upper pedestal portion 124 and a lower pedestal portion 125 that are integrally formed with the upper peripheral wall portion 122 and the lower peripheral wall portion 123, respectively. Here, both the upper pedestal portion 124 and the lower pedestal portion 125 have the same configuration, and the configuration of the restricting means is basically the same on the upper side and the lower side of the substrate box 92. The lower configuration will be described below as an example.

  As shown in FIG. 31, the lower pedestal portion 125 is formed so as to protrude from the inner wall surface of the lower peripheral wall portion 123 toward the flat surface portion 105 side of the back side structural body 102, and the lower peripheral wall portion 123 and the flat surface portion. 105 for both. The lower pedestal 125 is formed over the entire length direction (longitudinal direction) of the lower peripheral wall portion 123 or substantially the whole.

  The lower pedestal portion 125 stands up toward the front side structure 101. However, the height dimension (dimension in the thickness direction of the substrate box 92) is set smaller than the height dimension of the lower peripheral wall portion 123. In this regard, it can be said that the back side structure 102 has a stepped shape due to the lower peripheral wall portion 123 and the lower pedestal portion 125 at the edge on the long side.

  The lower pedestal portion 125 is formed with a locking receiver 121 corresponding to the hook portion 111 on a one-to-one basis. In other words, six locking receivers 121 are formed on the top and bottom. However, the specific number is arbitrary as long as it corresponds to the hook part 111 on a one-to-one basis. All the latch receivers 121 have the same shape and size.

  The locking receiver 121 is configured as a slit that penetrates the lower pedestal portion 125 in the height direction thereof, that is, in the thickness direction of the back side structure 102. Specifically, the locking receiver 121 includes an inner wall portion 126 that forms a boundary portion between the lower peripheral wall portion 123 that forms the peripheral surface as described above in the back side structure 102 and the flat portion 105 in the lower pedestal portion 125. Further, the periphery is defined by a connecting wall portion 127 formed so as to connect the lower peripheral wall portion 123 and the inner wall portion 126, and the thickness direction of the back side structure 102 (the thickness direction of the substrate box 92) Has penetrated.

  Incidentally, the connecting wall portion 127 also has a function of partitioning the adjacent locking receptacles 121 and faces the front side structural body 101 (the frame portion 112 of the front side structural body 101) at the lower pedestal portion 125. Is configured. Further, the inner wall portion 126 is formed so as to block the intrusion path into the substrate box 92 from the locking receiver 121 side, and the inner wall portion 126 constitutes a peripheral surface of the inner space of the substrate box 92. ing.

  The width dimension of the locking receiver 121, that is, the distance between the lower peripheral wall portion 123 and the inner wall portion 126 is set to be the same as or slightly larger than the thickness dimension of the hook portion 111. In addition, the length dimension of the locking receiver 121, that is, the distance between the opposing connecting wall portions 127 is set to be larger than the length dimension of the extending portion 116.

  As shown in FIG. 32A, the locking receiver 121 includes a receiving portion 128 that closes the slit-shaped locking receiver 121 on the one connecting wall portion 127 side. The connecting wall portion 127 on the side where the receiving portion 128 is formed is a side corresponding to the free end side of the hook portion 111 of both the connecting wall portions 127 in one locking receiver 121.

  The receiving portion 128 is formed at the end on the front side structural body 101 side in the locking receiver 121. Moreover, the receiving part 128 does not close the entire slit-like locking receiver 121 but only a part thereof. And the distance from the connection wall part 127 of the side in which the receiving part 128 is not formed in the latching receiver 121 to the receiving part 128 becomes larger than the length dimension of the extension part 116 of the hook part 111 in the extending direction. Yes. Thereby, in the configuration in which the receiving portion 128 is formed as described above, the hook portion 111 can be inserted into the locking receiver 121 from the front side of the back side structure 102. The receiving part 128 is set to have a thickness dimension that can enter the locking groove 117 of the hook part 111.

  The latch receiver 121 includes a closing portion 129 that closes the slit-shaped latch receiver 121 on the connecting wall 127 side opposite to the receiver 128. However, the closing portion 129 is formed at the end of the locking receiver 121 opposite to the side where the receiving portion 128 is formed. Further, the closing portion 129 does not close the entire slit-shaped locking receiver 121 but only a part thereof.

  In the state where the front side structural body 101 and the back side structural body 102 are integrated, as shown in FIGS. 32 (a) and 32 (b), the hook portion 111 is inserted into the locking receiver 121, As shown in FIG. 32A, the receiving portion 128 of the locking receiver 121 is inserted into the locking groove 117 of the hook portion 111. The receiving portion 128 is in contact with the frame portion 112 and is in contact with the extending portion 116 of the hook portion 111.

  In this case, even if the front side structure 101 and the back side structure 102 are moved and separated in the entering direction of the receiving part 128 with respect to the locking groove 117, the receiving part 128 is provided on the standing part 115 of the front side structural body 101. It is regulated by contacting. Further, even if the front side structural body 101 and the back side structural body 102 are separated in the thickness direction of the substrate box 92, they are restricted by the contact between the hook portion 111 and the receiving portion 128. Further, as shown in FIG. 32 (b), the hook portion 111 is sandwiched between both the lower peripheral wall portion 123 and the inner wall portion 126 that constitute the locking receiver 121. Therefore, even if the front side structural body 101 and the back side structural body 102 are moved up and down to be separated, the hook portion 111 is regulated by contacting either the lower peripheral wall portion 123 or the inner side wall portion 126. . That is, the direction in which the front side structure 101 and the back side structure are separated by the hook portion 111 and the locking receiver 121 is the direction in which the receiving portion 128 is extracted from the locking groove 117, that is, one short side of the substrate box 92. It is regulated on the side.

  In particular, a plurality of combinations of the hook portion 111 and the locking receiver 121 are provided on both long side portions of the substrate box 92, and further, these combinations are substantially the same in the length direction of each long side portion. It is performed at positions dispersed throughout. Therefore, the above regulations are strictly enforced.

  As shown in FIG. 32 (b), in the restricted state in which the hook portion 111 is inserted into the locking receiver 121 and the receiving portion 128 is inserted into the locking groove 117, the lower frame portion 114 of the front side structure 101. Are overlapped in the thickness direction of the lower pedestal 125 and the substrate box 92. In this case, the lower frame portion 114 is overlapped over the entire lower pedestal portion 125, and the inner space of the substrate box 92 is formed in the long side portion of the substrate box 92 by the lower pedestal portion 125 and the lower frame portion 114. A part of the peripheral surface is configured.

  As described above, the lower frame portion 114 is provided so as to stand from the base portion 110 of the front side peripheral edge portion 103 toward the back side structure 102. Further, the lower pedestal portion 125 is a portion constituting the slit-like locking receiver 121 as described above, and accordingly, is formed thicker than the lower frame portion 114. Further, the lower frame portion 114 is disposed at a position biased toward the lower peripheral wall portion 123 so as to contact the lower peripheral wall portion 123 on the lower pedestal portion 125. Therefore, as shown in FIG. 32 (b), a predetermined gap is formed between the base part 110 and the lower pedestal part 125 continuing to the lower frame part 114, and the main control board 91 is formed in the gap. Part of the peripheral edge of

  As described above, the lower peripheral wall portion 123 of the back-side structure 102 protrudes to the front-side structure 101 side with respect to the lower pedestal portion 125, and the protruding portion is outward with respect to the outer side surface of the lower frame portion 114. Are overlapping. Further, the lower peripheral wall portion 123 has an end surface on the leading end side thereof that is flush with the surface of the base portion 110 in the front peripheral edge portion 103. That is, the lower peripheral wall portion 123 overlaps the entire outer peripheral surface of one long side portion in the front side peripheral edge portion 103. Due to this configuration, the boundary of the long side portion between the front-side structure 101 and the back-side structure 102 is linear as shown in FIG.

  Moreover, the said boundary exists outside the base part 110 of the front side peripheral part 103, as shown in FIG.32 (b). Even if a fraudulent jig such as a lead wire is inserted into the internal space of the board box 92 through the boundary, the lower frame part 114 and the lower pedestal part 125 overlap with each other as described above. Is blocked. Furthermore, since the restriction by the hook portion 111 and the locking receiver 121 is firmly performed as described above, even if the lower frame portion 114 and the lower pedestal portion 125 are separated from each other, this is firmly prevented. .

  Here, by providing the hook portion 111 and the locking receiver 121 as described above, the restriction on the separation direction of the front side structure 101 and the back side structure 102 can be achieved while reducing the size of the substrate box 92. It is done firmly. This configuration will be described with reference to FIG. 33 in comparison with a configuration in which the size of the board box 92 becomes large. FIG. 33A is a cross-sectional view showing a restriction location of the substrate box 92 in the pachinko machine 10, and FIG. 33B is a cross-sectional view showing a restriction location of the substrate box 131 to be compared.

  The board box 92 of the pachinko machine 10 is provided with the hook part 111 and the locking receiver 121 as described above, so that the board can be moved from the edge of the internal space of the board box 92 to the board as shown in FIG. The distance to the peripheral surface of the box 92 is X1.

  On the other hand, in the board box 131 to be compared, as shown in FIG. 33 (b), the hook portion 132 and the locking receiver 133 are in the opposite relation to the board box 92, and the front side structure 134 and It is formed on the back side structure 135. That is, the hook portion 132 is formed on the back-side structure 135, and the locking receiver 133 is formed on the front-side structure 134. Further, in the substrate box 92, the edge portion of the front side structure 101 provided with the hook portion 111 constitutes a part of the peripheral surface of the internal space in the substrate box 92, but in the substrate box 131, the hook portion 132 is formed. The edge part of the provided back side structure 135 does not constitute a part of the peripheral surface of the internal space. Therefore, the distance from the edge of the internal space of the substrate box 131 to the peripheral surface of the substrate box 131 is X2, which is longer than the distance X1 of the corresponding portion in the substrate box 92 by X3.

  As described above, according to the substrate box 92 of the pachinko machine 10, the separation of the front side structure 101 and the back side structure 102 is firmly regulated while the size of the substrate box 92 is reduced. In the pachinko machine 10, it is preferable to increase the size of the display screen of the symbol display device 41 and to make the pachinko machine 10 multifunctional. However, if an attempt is made to increase the size of the display screen or to make the pachinko machine 10 multifunctional, a space for mounting electrical devices on the back side of the pachinko machine 10 is limited. In contrast, by reducing the size of the substrate box 92 as described above, it is possible to satisfactorily realize an increase in the size of the display screen and the increase in the number of functions of the pachinko machine 10.

  Next, the assembling work of the front side structure 101 and the back side structure 102 by the restriction means will be described with reference to FIG. FIGS. 34A to 34C are explanatory views for explaining the assembly work of the front side structure 101 and the back side structure 102.

  When the front-side structure 101 and the back-side structure 102 are fixed to each other, the hook portion 111 is first engaged from the back side of the back-side structure 102 so that the state shown in FIG. 34 (a) is changed to the state shown in FIG. 34 (b). Insert into the catch 121. In this case, the free end of the hook part 111 faces the receiving part 128 side in the inserted locking receiver 121. Further, in this state, the front-side structure 101 and the back-side structure 102 are not completely overlapped but are shifted in the left-right direction.

  After that, at least one of the front-side structure 101 or the back-side structure 102 is slid in the direction in which both the structures 101 and 102 completely overlap with each other, as shown in FIG. The receiving portion 128 of the locking receiver 121 enters the working groove 117. Thereby, the moving direction of the front side structural body 101 and the back side structural body 102 is regulated so as to be movable only in the direction in which the receiving portion 128 is removed from the locking groove 117. In this state, the fixing by the fixing means makes it impossible to move in the movement direction restricted by the restricting means, and the front structure 101 and the back structure 102 are fixed to each other.

  Next, the fixing means will be described.

  As shown in FIGS. 30 and 31, a front-side coupling region 141 is integrally formed on one short side portion of the front-side structure 101. The front side coupling region 141 is formed to extend laterally from the bulging portion 104 at the short side portion. A plurality (specifically, four) of front side coupling portions 142 and 143 are provided in the front side coupling region 141, and each front side coupling portion 142 and 143 has a through-hole portion penetrating in the thickness direction of the substrate box 92. 144 is formed. In the present embodiment, the front-side coupling portion used when manufacturing the main control device 63 and the main control device 63 are used to re-box both components 101 and 102 after the main control device 63 is opened. There are two different types of front side coupling parts. Hereinafter, for convenience of explanation, the former will be referred to as “first front side coupling portion 142” and the latter will be referred to as “second front side coupling portion 143”.

  Each front side coupling | bond part 142,143 is provided in parallel along the said short side part. More specifically, two second front side coupling portions 143 are disposed between two first front side coupling portions 142 that are spaced apart along the short side portion. In addition, each first front side coupling portion 142 is coupled to the bulging portion 104 via the first coupling portion 145 and is coupled to the adjacent second front side coupling portion 143 via the second coupling portion 146. . In this case, a space in which a tool such as a nipper or a cutter can be inserted is secured around each of the connecting portions 145 and 146, and it is easier to cut with the above tool than destroying the first front side coupling portion 142. ing. In addition, it is also possible to abbreviate | omit the 2nd connection part 146 mentioned above. Incidentally, the details of the differences between the first front side coupling portion 142 and the second front side coupling portion 143 will be described later.

  Corresponding to the front side binding region 141, a back side binding region 151 is provided on the back side peripheral edge portion 106 of the back side structure 102 (see FIG. 35, etc.). Here, in the substrate box 92, the back side coupling region 151 has a characteristic configuration. Therefore, the configuration relating to the coupling will be described below while focusing on the characteristic configuration of the back-side coupling region 151.

  The coupling region forming portion 152 is formed over the whole or substantially the whole in one short side portion of the back side peripheral portion 106 of the back side structure 102. As shown in FIG. 35, the coupling region forming portion 152 is formed with a groove portion 155 that is open toward the front structure 101 side. The groove portion 155 is formed over the entire coupling region forming portion 152.

  A receiving member 153 is fixed to the coupling region forming portion 152 in a state of being inserted into the groove portion 155. The receiving member 153 is formed by bending a metal plate that is at least stronger (hard) than the wall portion of the back-side structure 102 at a plurality of locations as shown in FIG. 155 has the same or substantially the same length. Note that the receiving member 153 may be formed by welding a plurality of metal plates rather than by bending the metal plate.

  The receiving member 153 includes a receiving base portion 162 formed so as to have a recessed space 161 along the peripheral surface of the groove portion 155, and a hook plate portion 163 integrally formed with the receiving base portion 162. I have. In this case, the receiving base portion 162 includes opposed plate portions 164 and 165 facing each other and a connecting plate portion 166 that connects the opposed plate portions 164 and 165 at one end, and each of these plate portions 164 and 165. , 166 form a recessed space 161. Further, the hooking plate portion 163 is also plate-shaped, and a part of the plate portions faces the inner facing plate portion 164.

  The receiving member 153 is installed in the coupling region forming portion 152 so that the outer peripheral surface of the receiving base portion 162 overlaps with the inner peripheral surface of the groove portion 155. In this case, the hook plate portion 163 is in a state of being hooked on the inner groove wall portion 156 among the wall portions forming the groove portion 155 in the coupling region forming portion 152. Further, as shown in FIGS. 31 and 36, among the opposing plate portions 164 and 165 of the receiving base portion 162, the outer opposing plate portion 165 (hereinafter referred to as the outer opposing plate portion 165) has a locking recess 167. Are formed at a plurality of locations, and as shown in FIG. 31, a locking portion 158 is provided on the outer groove wall portion 157 among the wall portions defining the groove portion 155 in the coupling region forming portion 152. It is integrally formed. The locking portions 158 are formed at a plurality of locations in a one-to-one correspondence with the locking recesses 167.

  In a state where the receiving member 153 is installed in the coupling region forming portion 152, the locking recess 167 is locked by the locking portion 158, and the receiving member 153 is fixed to the coupling region forming portion 152. In a state where the receiving member 153 is fixed to the coupling region forming portion 152, the recessed space 161 in the receiving base portion 162 is opened toward the front-side component 101, and the receiving base portion 162 is substantially entirely in the groove portion 155. It is located across.

  That is, as shown in FIG. 30, the receiving member 153 is located over substantially the entire short side of the substrate box 92. In other words, the receiving member 153 is provided so as to be located over the whole or substantially the whole between the corner portions of at least a predetermined peripheral surface portion of the plurality of peripheral surface portions of the substrate box 92. In other words, the substrate box 92 is formed in a polygonal shape (rectangular shape) when viewed from the front, and the receiving member 153 is located over the whole or substantially the entire extending direction of the side of the predetermined side. Is provided.

  Of the opposing plate portions 164 and 165 of the receiving member 153, the inner opposing plate portion 164 (hereinafter referred to as the inner opposing plate portion 164) is engaged so as to protrude toward the recessed space 161 as shown in FIG. A stop piece 168 is provided. As shown in the broken portion in FIG. 36, the locking piece 168 is formed by cutting the inner facing plate portion 164 in a range where the inner facing plate portion 164 is not cut, and bending the portion that has become a plate spring shape by cutting to the concave space 161 side. ing. In this case, the free end of the locking piece 168 faces the connecting plate portion 166 side of the receiving base portion 162, that is, the back side of the recessed space 161. A plurality of the locking pieces 168 are formed at equal intervals. The number of the locking pieces 168 is the same as the number of the front side coupling portions 142 and 143 formed in the front side coupling region 141, and the positions of the front side coupling portions 142 and 143 are the same. It is formed corresponding to.

  As described above, the cover member 154 is installed on the coupling region forming portion 152 to which the receiving member 153 is fixed. The cover member 154 is formed of a colorless and transparent polycarbonate resin, but the forming material is not limited to this, and may be an acrylic resin or the like. The cover member 154 has the same or substantially the same length as the coupling region forming part 152, and has a function of covering the whole or substantially the whole of the coupling region forming part 152 and the receiving member 153. It has a function for partitioning the coupling region forming portion 152 to which the member 153 is fixed into the same number of back side coupling portions 176 as the front side coupling portions 142 and 143.

  Specifically, as shown in FIG. 35, the cover member 154 includes a first cover plate portion 172 and a second cover plate portion 173 that is orthogonal to the first cover plate portion 172. 171. When the cover member 154 is installed in the coupling region forming portion 152, the first cover plate portion 172 has the groove walls 156 and 157 facing the coupling region forming portion 152 and the receiving member 153 fixed to the coupling region forming portion 152. On the other hand, the second cover plate portion 173 overlaps the entire outer peripheral surface of the outer groove wall portion 157 in the coupling region forming portion 152 from the outside, overlapping from the open side of the recessed space 161 of the receiving member 153. ing.

  As shown in FIG. 37A, the first cover plate portion 172 is formed with a plurality of through-hole portions 174 at equal intervals in the length direction. By forming the through hole portion 174, the recessed space 161 of the receiving member 153 is not completely closed by the first cover member 154, and is directed toward the front-side component 101 at the position of the through hole portion 174. Open.

  The through-hole portion 174 has a one-to-one correspondence with the locking piece 168 of the receiving member 153, and as shown in FIG. 35, one through-hole portion 174 and one in the position aligned in the thickness direction of the substrate box 92. The locking piece 168 is located. Moreover, the through-hole part 174 has a one-to-one correspondence with the front side coupling parts 142 and 143.

  On the surface side of the first cover plate portion 172, as shown in FIGS. 37 (a) and 37 (b), regions where the through-hole portions 174 are formed on the surface side of the first cover plate portion 172 are individually provided. A partition wall 175 is integrally formed so as to partition. And the back side coupling | bond part 176 is comprised by each area | region divided by the division wall part 175. FIG. Each back side coupling part 176 is opened toward the front side structure 101 and is also opened toward the short side part facing the short side part on the side where the back side coupling region 151 is formed in the back side structure 102. Yes. Each back side coupling portion 176 has a size that can accommodate the corresponding front side coupling portion 142, 143, and in the state where each front side coupling portion 142, 143 corresponding to each back side coupling portion 176 is accommodated, each front side The through holes 144 of the coupling parts 142 and 143 and the through holes 174 of the back side coupling parts 176 are in communication with each other.

  As shown in FIG. 37B, positioning protrusions 177 are provided at a plurality of locations on the back surface side of the first cover plate portion 172. These positioning protrusions 177 have a plate shape that stands up from the first cover plate portion 172, and are formed so that the plate thickness dimension is equal to the distance between the opposing plate portions 164 and 165 of the receiving member 153. ing. When the cover member 154 is installed, these positioning projections 177 enter the recessed space 161 of the receiving member 153 so that the mounting direction is defined and the installation location can be easily positioned. Further, when the projection 177 enters the recessed space 161 of the receiving member 153, the direction in which the cover member 154 is detached from the installation location is defined. In other words, it is defined in the direction in which the recessed space 161 is opened, that is, the direction from the back side structure 102 to the front side structure 101.

  Here, the configuration relating to the removal restriction of the cover member 154 will be described with reference to FIG. 38A in addition to FIG. 31, FIG. 36 and FIG. FIG. 38A is a partial cross-sectional view taken along line BB in FIG.

  As shown in FIG. 31 and the like, a cylindrical portion 178 is integrally formed at the center of the first cover plate portion 172 so as to stand from the first cover plate portion 172 to the front side structure 101 side. The first cover plate portion 172 is formed with a round hole 179 that communicates with the hole portion 178 a of the cylindrical portion 178 and extends in the same direction as the axial direction of the cylindrical portion 178. More specifically, the hole 178a and the round hole 179 are continuous in a step shape, and the diameter of the hole is reduced in the round hole 179.

  Further, as shown in FIGS. 31 and 36, the receiving member 153 is formed with a communication hole 169 communicating with the round hole 179, and the hole 178a, the round hole 179, and the communication hole 169 include the front side structure 101. A breaking screw 170 is inserted from the side. A mounting hole 159 into which the breaking screw 170 is screwed is formed in the back side structure 102, and the breaking screw 170 is screwed into the mounting hole 159, whereby the back side structure 102 and the receiving member are formed. 153 and the cover member 154 are integrated.

  It should be noted that the breaking screw 170 is more difficult in the latter case when comparing the mounting operation and the removing operation, and it is accompanied by the destruction of at least one of the fixing target and itself after being mounted once. The removal is impossible. More specifically, the strength of the connecting portion 170b between the head portion 170a into which the tip of a tool such as a screwdriver can be inserted and the side on which the screw groove is formed is set low, and is tightened further. When a predetermined force is further applied to the head 170a at a position where it cannot be performed by the tool, the connecting portion 170b is cut and the head 170a is separated. That is, the break screw 170 cannot be rotated in the loosening direction using the tool after screwing. In addition, the fracture | rupture screw | thread 170 currently screwed by the back side structure 102 has isolate | separated the head 170a after screwing.

  Incidentally, if it is possible to prevent loosening of the connection between the back-side structure 102 and the cover member 154 after screwing, the fixing member that connects the back-side structure 102 and the cover member 154 is the breaking screw 170. The known one-way screw may be used.

  As shown in FIG. 38, the connecting portion 170 b of the breaking screw 170 is accommodated in the hole 178 a of the cylindrical portion 178. That is, the connecting portion 170b is surrounded by the cylindrical portion 178. Thus, if attention is paid to the function of enclosing the connecting portion 170b, the cylindrical portion 178 can also be referred to as “enclosure”, and if attention is paid to the function of accommodating the connecting portion 170b therein, it is referred to as “accommodating portion”. Is also possible.

  Here, the relationship between the breaking screw 170 and the cylindrical portion 178 will be described in detail. The rising amount X5 of the cylindrical portion 178 is set to be larger than the protruding amount X6 of the breaking screw 170 (specifically, the connecting portion 170b) from the first cover plate portion 172, and the breaking screw 170 is mainly used by the cylindrical portion 178. Exposure to the side of the control device 63 is avoided.

  Further, in a state where the two structural bodies 101 and 102 are combined with each other, the front-side structural body 101 is located on the central axis of the round hole 179. This front side structure 101 prevents access to the breaking screw 170. Specifically, as shown in FIG. 38, a shielding portion 180 that closes the open portion of the cylindrical portion 178 is integrally formed in the front-side coupling region 141 of the front-side structure 101. The shielding part 180 is in a state of being substantially in contact with (close to) the cylindrical part 178 and, together with the cylindrical part 178, defines a closed space in which the connecting part 170b of the breaking screw 170 is accommodated. The shielding part 180 has a plate shape extending in the longitudinal direction of the substrate box 92, that is, on the side opposite to the regulation direction by the regulation means, and avoids catching with the cylindrical part 178 when the two structural members 101 and 102 are combined. Has been. It is also possible to adopt a configuration in which the shielding portion 180 and the cylindrical portion 178 are in contact (contact).

  Furthermore, the standing amount X5 of the cylindrical portion 178 is set to be smaller than the protruding amount X7 of the breaking screw 170 from the first cover plate portion 172 in a state where the head 170a of the breaking screw 170 remains. For this reason, in the state where the head 170a of the breaking screw 170 is not separated, that is, in the state where the removal of the breaking screw 170 is not restricted, if both the structural members 101 and 102 are combined, the breaking screw 170 is broken. The head 170a of the screw 170 and the shield 180 come into contact with each other, and movement to a predetermined assembly position is prevented. That is, the shielding portion 180 has a function of preventing the forgetting to remove the head 170a of the breaking screw 170 in addition to the shielding function for suppressing the exposure of the breaking screw 170.

  Also, as shown in FIG. 38 (b), a state in which both constituent members 101, 102 are combined, more specifically, although both constituent members 101, 102 are combined as shown in FIG. 34 (b), they are still positioned relative to each other. In the shifted state, the central axis of the round hole 179 (the attachment / detachment path of the breaking screw 170) and a part of the shielding part 180 overlap. In other words, the passage region E1 of the breaking screw 170 and a part of the shielding portion 180 when the breaking screw 170 is attached / detached are not only in the mounting completion state of both the structural members 101 and 102 but also at least in the locking receiver 121. On the other hand, when the hook part 111 is hooked, it is configured to overlap. For this reason, in order to release the removal restriction of the breaking screw 170 by the shielding part 180, it is necessary to first separate both the structural bodies 101 and 102, and the both structural bodies 101 and 102 are slightly displaced in the regulation direction by the regulating means. As a result, the inconvenience that unauthorized removal of the breaking screw 170 is facilitated is less likely to occur.

  Next, a flow of work for forming the back side coupling region 151 and a flow of work for combining the two structural members 101 and 102 will be described with reference to FIGS. FIGS. 39A to 39D are explanatory views for explaining the work in forming the back side coupling region 151. 39 (a) and 39 (b) and FIGS. 17 (c) and 17 (d) show cross sections at positions shifted in the longitudinal direction of the cover member 154 for convenience of explanation.

  As shown in FIG. 39B, a receiving member 153 is installed on the coupling region forming portion 152 of the back side structure 102 shown in FIG. In the installation, the receiving base portion 162 of the receiving member 153 enters the groove portion 155 of the coupling region forming portion 152 and the hooking plate portion 163 of the receiving member 153 is hooked on the inner groove wall portion 156 of the coupling region forming portion 152. It is performed so that it will be in the state.

  As shown in FIG. 39 (b), the receiving base portion 162 of the receiving member 153 overlaps the inner peripheral surface of the groove portion 155 of the coupling region forming portion 152, so that the locking concave portion 167 of the receiving base portion 162. Is locked by the locking portion 158 of the coupling region forming portion 152. The locking portion 158 has a tip protruding into the groove portion 155, but the locking portion 158 is formed to be elastically deformable to a position that does not hinder the entry when the receiving base portion 162 enters the groove portion 155. ing.

  Thereafter, the cover member 154 is installed in the coupling region forming unit 152 where the receiving member 153 is installed. At this time, since the positioning projection 177 is formed on the cover member 154, the cover member 154 can be installed satisfactorily. Moreover, when the cover member 154 is installed, the latching | locking part 158 is covered from the outer side by the said cover member 154 (refer FIG.29 and FIG.31). Further, the portion where the locking portion between the locking portion 158 and the locking recess 167 at the opening portion of the groove portion 155 is exposed is also covered with the cover member 154. As a result, even if the locking state between the locking portion 158 and the locking recess 167 is illegally released, the act becomes difficult to perform. Note that the cover member 154 and the back-side component 102 are hooked based on the pushing operation of the cover member 154 to the mounting completion position, and the removal of the cover member 154 is restricted. The configuration related to the hooking between the cover member 154 and the back side structure 102 and the details related to the mounting operation of the cover member 154 will be described later.

  Next, as shown in FIG. 39C, the breaking screw 170 is inserted into the cylindrical portion 178 (specifically, the hole 178a) of the cover member 154. Then, the breaking screw 170 is inserted into the round hole 179 and the communication hole 169, and the breaking screw 170 is screwed into the mounting hole 159 using a tool such as a screwdriver. By screwing the fracture screw 170 to a position where it cannot be tightened any more, the cover member 154 is fixed to the back side structure 102. That is, the cover member 154, the receiving member 153, and the back-side structure 102 are integrated, and the formation of the back-side coupling region 151 is completed.

  In this manner, in a state where the cover member 154 is fixed, a predetermined force is further applied to the tool to cut the connecting portion 170b of the breaking screw 170 (see FIG. 39D). As a result, the head 170a of the breaking screw 170 is separated, and the head 170a can be removed. Then, by separating the head portion 170a in this way, it becomes difficult to remove the breaking screw 170, and the removal of the cover member 154 and the receiving member 153 from the back side structure 102 is restricted.

  Thereafter, as shown in FIG. 38A, the two structural members 101 and 102 are combined by relatively moving the two structural members 101 and 102 in a predetermined direction. In such a case, since the head 170a of the breaking screw 170 is removed, the movement of the two structural members 101 and 102 to the assembly completion position is allowed. Specifically, the interference between the breaking screw 170 and the shielding portion 180 of the front structure 101 is avoided, and the movement to the assembly completion position described above is allowed. Thus, in the state where the assembly of both the constituent members 101 and 102 is completed, the shielding portion 180 is positioned on the removal track of the breaking screw 170. More specifically, the opening of the cylindrical portion 178 is blocked by the shielding portion 180, and exposure of the breaking screw 170 (specifically, the connecting portion 170b) is suppressed. This makes it difficult to access the breaking screw 170 from the outside of the board box 92. Therefore, even if the breaking screw 170 is illegally removed, it is difficult to perform the action.

  Here, the mutual positional relationship between the fixing part (round hole 179) of the cover member 154 and the front side coupling portions 142 and 143 will be described. As shown in FIG. 30 etc., the 1st front side coupling | bond part 142 is arrange | positioned on both sides which pinched | interposed the fixing | fixed site | part of the cover member 154. As shown in FIG. More specifically, the first front side coupling portion 142 is disposed so as to be biased to both short sides of the cover member 154. And the 2nd front side coupling | bond part 143 is arrange | positioned between the fixed site | part of these cover members 154, and the 1st front side coupling | bond part 142, respectively. In other words, the fixing portion of the cover member 154 is in a state of being doubled between the first front side coupling portion 142 and the second front side coupling portion 143. That is, the distance dimension between the fixed part and the first front side coupling part 142 is set larger than the distance dimension between the fixed part and the second front side coupling part 143.

  Next, a configuration related to the coupling between the front side coupling portions 142 and 143 and the back side coupling portion 176 will be described. As described above, the configuration related to the coupling between the first front side coupling portion 142 and the second front side coupling portion 143 is partially different. Therefore, first, the first front side coupling portion 142 will be described in detail with reference to FIG. 40A, and then the second front side coupling portion 143 will be described based on differences from the first front side coupling portion 142. FIG. 40A is a cross-sectional view showing a connecting portion between the first front side connecting portion 142 and the back side connecting portion 176 in the substrate box 92.

  In the state where each first front side coupling portion 142 corresponding to each back side coupling portion 176 is accommodated, as described above, it is formed in the through hole portion 144 and the first cover plate portion 172 of each first front side coupling portion 142. In addition, the corresponding through-hole portions 174 are in communication with each other. As shown in FIG. 40A, a metal first coupler (fixing tool) 181 is inserted into the through-hole portions 144 and 174 communicated with each other from the first front-side coupling portion 142 side. Thus, the first front side coupling portion 142 and the back side coupling portion 176 are coupled (fixed).

  The first coupler 181 is formed by bending a long metal plate into a substantially L shape, and includes a base portion 181a inserted through the through-hole portions 144 and 174, and one side of the base portion 181a. The operation part 181b is formed at the end part and is orthogonal to the base part 181a. The base portion 181a is formed with a locking hole portion 181c penetrating in the thickness direction, and the locking piece 168 enters the locking hole portion 181c by inserting the first coupler 181. In this case, since the locking piece 168 functions as a leaf spring as described above, and the free end is directed to the back side of the recessed space 161, the movement of the first coupler 181 in the insertion direction is not performed. Although not regulated, the movement of the first coupler 181 in the extraction direction is regulated after the locking piece 168 enters the locking hole 181c. Thereby, the 1st front side coupling | bond part 142 and the back side coupling | bond part 176 are couple | bonded, and the front side structural body 101 and the back side structural body 102 are fixed. When inserting the first coupler 181, the operation can be easily performed by pressing the operation unit 181 b with a finger or the like.

  The operation portion 181b is formed at the end portion of the base portion 181a on the front side coupling portion 142 side, and in a mounted state, the plate surface abuts on the abutting portion 142a of the first front side coupling portion 142. . The contact portion 142a has a substantially plate shape parallel to the plate surface of the operation portion 181b. The operation part 181b and the contact part 142a contact each other, so that the front side coupling part 142 is sandwiched between the operation part 181b and the back side coupling part 176. That is, both the coupling portions 142 and 176 are coupled.

  The front side coupling region 141 (specifically, the first front side coupling part 142) is formed with a first peripheral wall part 142b that stands up around the contact part 142a and accommodates the operation part 181b therein. In other words, the housing recess 182 that houses the operation portion 181b is formed by the first peripheral wall portion 142b. The inner periphery of the housing recess 182 is set to be substantially the same as the outer periphery of the operation portion 181b (see FIG. 30), and after the operation portion 181b is housed in the housing recess 182, it is difficult to grasp the operation portion 181b. ing. Thereby, the unauthorized removal of the 1st coupling tool 181 is suppressed.

  Next, the structure related to the 2nd front side coupling | bond part 143 and the said 2nd front side coupling | bond part 143 is demonstrated based on FIG.40 (b). FIG. 40B is a cross-sectional view showing a connection portion between the second front side connecting portion 143 and the back side connecting portion 176 in the substrate box 92.

  Similar to the first front side coupling portion 142, the second front side coupling portion 143 includes a contact portion 143a and a peripheral wall portion 143b. Similarly to the first coupler 181, a second coupler (fixer) 183 that couples (fixes) the second front-side coupler 143 and the back-side coupler 176 is provided. A housing recess 184 capable of housing the second coupler 183 is formed by the wall surfaces of the peripheral wall portion 143b and the bulging portion 104. The second coupler 183 fits into the housing recess 184 and the through-hole portions 144, 174 are accommodated. The second front side coupling portion 143 and the back side coupling portion 176 are coupled to each other.

  The second coupler 183 is formed by bending a long metal plate into a substantially L shape, and includes a base portion 183a inserted through the through-hole portions 144 and 174, and one side of the base portion 183a. An operation portion 183b that is formed at the end and is orthogonal to the base portion 183a is configured. The base portion 183a is formed with a locking hole portion 183c penetrating in the thickness direction, and the locking piece 168 enters the locking hole portion 183c by inserting the second coupler 183. In this case, the locking piece 168 has a function as a leaf spring as described above, and since the free end is directed to the back side of the recessed space 161, the movement of the second coupler 183 in the insertion direction is not performed. Although not regulated, the movement of the second coupler 183 in the extraction direction is regulated after the locking piece 168 has entered the locking hole 183c. Thereby, the 2nd front side coupling | bond part 143 and the back side coupling | bond part 176 are couple | bonded, and the front side structural body 101 and the back side structural body 102 will be fixed.

  The peripheral wall portion 143 b is continuous with the bulging portion 104 of the front side structure 101. That is, unlike the first front-side coupling portion 142, a portion corresponding to the connecting portion 145 that facilitates detachment from the front-side structure 101 (which facilitates cutting) is not provided. Therefore, when the 2nd front side coupling | bond part 143 is couple | bonded, the isolation | separation of both the structural bodies 101 and 102 becomes impossible or difficult.

  A regulating portion 143 c that regulates the insertion direction of the second coupler 183 in a predetermined direction, specifically, the axial direction of the through-hole portion 144 is formed inside the housing recess 184. The restricting portion 143c includes a plurality of (two in the present embodiment) columnar portions extending in the axial direction of the through-hole portion 144. More specifically, the restricting portion 143c faces the peripheral wall portion 143b with the through hole 144 interposed therebetween, and the distance between the restricting portion 143c and the peripheral wall portion 143b is the thickness of the base portion 183a of the second coupler 183. It is almost the same as the dimensions. The insertion direction of the second coupler 183 inserted toward the through-hole portion 144 is restricted by fitting the base portion 183a into a region sandwiched between the restriction portion 143c and the peripheral wall portion 143b.

  The operation portion 183b is configured such that the maximum length dimension from the bent proximal end side to the distal end side in the operation portion 183b is substantially equal to the interval dimension between the peripheral wall portions 143b facing each other in the length direction. The tip edge is close to the peripheral wall portion 143b. Further, the operation portion 183b is configured to be approximately equal to the maximum width dimension (width dimension in a direction orthogonal to the length direction) and the interval dimension between the peripheral wall portions 143b facing each other in the width direction. Edges on both sides in the width direction are close to the peripheral wall portion 143b. As described above, the edge portions are brought close to the peripheral wall portion 143b, thereby making it difficult to grasp the operation portion 183b. Thereby, it is possible to make the pulling operation of the operation unit 183b difficult while maintaining the ease of the pressing operation of the operation unit 183b. In addition, you may make each edge part in the operation part 183b contact | abut with respect to the surrounding wall part 143b.

  As shown in FIG. 30 and the like, a notch 183d corresponding to the restricting portion 143c is formed in the operation portion 183b of the second coupler 183. Specifically, the cutout portion 183d is formed by deleting a portion of the operation portion 183b that faces the restriction portion 143c in the axial direction of the through-hole portion 144. For this reason, even if the second coupler 183 is pushed in a predetermined direction regulated by the regulating part 143c, the movement of the second coupler 183 is not hindered by these regulating parts 143c. Contact between the operation portion 183b and the contact portion 143a of the second front side coupling portion 143 is secured.

  The restricting portion 143c is disposed along the peripheral wall portion 143b. Thereby, it is difficult to cause the inconvenience that the finger hits the restricting portion 143c in accordance with the pressing operation of the operation portion 183b. That is, the operability of the operation unit 183b is ensured.

  The second coupler 183 is configured to be temporarily fixed (locked) inside the housing recess 184, that is, to be held in a standby state before coupling. Hereinafter, the specific configuration will be described with reference to FIGS. 31 and 41. 41 is a partial cross-sectional view taken along the line CC of FIG.

  As shown in FIG. 41, a locking claw portion 143d as a temporary locking portion that protrudes inward and hooks into the locking hole portion 183c is formed inside the accommodation recess 184 (specifically, the peripheral wall portion 143b). The peripheral wall portion 143b is formed with a movable body-side movable portion 143e that allows the portion including the locking claw portion 143d to bend and deform (elastically deform) based on the insertion of the second coupler 183 (see FIG. 31). ). The structure-side movable portion 143e has a function as a leaf spring, and the amount of protrusion of the engaging claw portion 143d to the inside of the housing recess 184 is reduced by being flexibly deformed (elastically deformed). It has become.

  On the other hand, the partition wall portion 175 has a cover side movable portion so that the region including the portion facing the component side movable portion 143e in the partition wall portion 175 can be deformed (elastically deformed) independently of the other portions. 175a is formed. Specifically, the cover-side movable part 175a has cuts formed on both sides of the partition wall part 175 including a region including the part facing the component-side movable part 143e. 175 can be deformed independently with respect to the peripheral region.

  When the second coupler 183 is inserted into the housing recess 184, the locking claw 143d and the base 183a of the second coupler 183 come into contact. Based on the pushing operation of the second coupler 183, the component-side movable portion 143e is deformed (elastically deformed), and accordingly, the cover-side movable portion 175a is also deformed (elastically deformed). That is, both movable parts 143e and 175a are bent together. Thereby, the protrusion amount of the latching claw part 143d is reduced, and the insertion of the second coupler 183 is allowed. Specifically, the locking claw portion 143d rides on the plate surface of the base portion 183a, and the locking claw portion 143d slides on the plate surface of the base portion 183a as the second coupling tool 183 moves. In such a state, the locking claw 143d is maintained while being urged toward the base portion 183a by the elastic force of both the movable portions 143e and 175a.

  When the second coupler 183 is pushed to a predetermined position, the locking claw 143d can be fitted into the locking hole 183c. In such a case, both the movable parts 143e and 175a try to return to the original state by their own elastic force, so that the locking claw part 143d fits into the locking hole part 183c, and the locking claw part 143d is locked. The hole 183c is caught. Thereby, the 2nd coupling tool 183 is temporarily fixed.

  As shown in FIG. 41, when the locking claw portion 143d is hooked to the locking hole portion 183c, that is, in the temporarily fixed state, the tip of the base portion 183a protrudes from the through-hole portion 144 (rear side coupling) Projecting toward the portion 176 side) is avoided. For this reason, the relative movement of the two structural members 101 and 102 is not hindered by the second coupler 183 temporarily fixed. Furthermore, in a state where the second coupler 183 is temporarily fixed, the operation portion 183b is housed in the housing recess 184, and it is difficult to grasp the operation portion 183b. For this reason, it is difficult to remove the second coupler 183 after temporarily fixing the second coupler 183.

  As shown in FIG. 29, the cover-side movable portion 175a is in contact with not only the component-side movable portion 143e but also the peripheral wall portion 143b (specifically, both sides of the peripheral-wall portion 143b sandwiching the component-side movable portion 143e). . For this reason, if the cover side movable part 175a is pushed from the outside of the main controller 63, the load applied to the cover side movable part 175a can be dispersed by the peripheral wall part 143b, and the structure side movable part 143e Thus, it is possible to avoid local concentration of load. Further, the cover side movable portion 175a is in contact with a portion including at least the movable tip side of the component side movable portion 143e. Thereby, it is possible to suitably suppress the operation of the component side movable portion 143e from the outside.

  According to the component side movable portion 143e and the cover side movable portion 175a described in detail above, it is possible to suppress an unauthorized operation from the outside while allowing the bending deformation of the component side movable portion 143e, and a practically preferable configuration. Can be realized.

  Both the coupling members 181 and 183 are made of metal so as to have higher strength than the wall portion of the back side structure 102. The synthetic resin material may be made of a synthetic resin material, or may be formed of a material in which a reinforcing agent such as glass fiber is dispersed in a synthetic resin material. You may form by performing the surface treatment of.

  As described above, the direction in which the cover member 154 is removed from the installation location is restricted by the protrusion 177 in the direction from the back side structure 102 to the front side structure 101, so that the front side connection part 142 is located with respect to the back side connection part 176. By being in the superimposed state, the movement in the direction in which the cover member 154 is detached is more preferably regulated. Then, the front side coupling portion 142 and the back side coupling portion 176 are coupled to each other, so that the cover member 154 is sandwiched between the front side coupling portion 142 and the coupling region forming portion 152 so that there is no play.

  As shown in FIG. 40, the cover member 154 is integrally formed with a receiving plate portion 185 so as to enter the internal space of the substrate box 92 from the first cover plate portion 172. As shown in FIG. 37 (b), the receiving plate portion 185 is provided at a plurality of locations so as to be located over the entire length of the cover member 154. As shown in FIG. A base end portion 186 extending from the one cover plate portion 172 toward the back side structural body 102 side, and a front end portion 187 extending from the base end portion 186 toward the center side of the internal space of the substrate box 92 are provided. The front end portion 187 of the receiving plate portion 185 is in contact with a support base portion 188 formed adjacent to the coupling region forming portion 152 in the back side structure 102 with the cover member 154 installed in the coupling region forming portion 152. . Further, the front end portion 187 of the receiving plate portion 185 is a state of the main control board 91 integrated with the frame portion 112 of the front side structural body 101 and the front side structural body 101 in a state where the front side structural body 101 is combined with the back side structural body 102. It will be in the state where the peripheral part got on. That is, the front end portion 187 of the receiving plate portion 185 is sandwiched between the support base portion 188 of the back side structure 102, the frame portion 112 of the front side structure 101, and the peripheral edge portion of the main control board 91. Thereby, the cover member 154 is fixed in a more stable state.

  Next, the flow of work when the front side coupling portions 142 and 143 and the back side coupling portion 176 are in the coupled state will be described with reference to FIG. 42 (a) to 42 (c) are explanatory diagrams for explaining the flow of work when the first front-side coupling portion 142 and the back-side coupling portion 176 are in the coupled state.

  As shown in FIG. 42A, the front side structure 101 is combined with the back side structure 102 in a state where the receiving member 153 and the cover member 154 are installed in the coupling area forming portion 152 and the back side coupling area 151 is formed. Thus, as shown in FIG. 42 (b), the through-hole portion 144 of the first front-side coupling portion 142 and the corresponding through-hole portion 174 of the back-side coupling portion 176 are in communication with each other. In this case, the first front side coupling portion 142 naturally corresponds to each back side coupling portion 176 of the back side coupling region 151 by being regulated by the regulation means including the hook portion 111 and the locking receiver 121. The first front side coupling portion 142 is accommodated, and the through hole portions 144 and 174 are communicated as described above.

  Thereafter, as shown in FIG. 42 (c), the first couplers 181 are inserted into the through-hole portions 144 and 174 communicated with each other by inserting the first couplers 181 from the first front side coupler 142 side. The combination of the first front-side coupling portion 142 and the back-side coupling portion 176 into which is inserted is in a coupled state, and the front-side structural body 101 and the back-side structural body 102 are fixed. In this case, a plurality of combinations (specifically, two sets) of the first front side coupling portion 142 and the back side coupling portion 176 are provided, and the first coupling 181 is inserted into each of these combinations. Thus, the front side structure 101 and the back side structure 102 are fixed.

  In the manufacturing process of the main controller 63, as described above, the first front side coupling portion 142 and the back side coupling portion 176 are joined together with the second front side coupling portion 143 and the back side coupling portion 176 to be in a standby state (temporary). Preliminary work (to stop) is performed. The preliminary work will be described with reference to FIG. 41 again.

  After the joining work of the first front side joining part 142 and the back side joining part 176 is finished, the temporary fastening work of the second joining tool 183 is performed. Specifically, the second coupler 183 is inserted from the opening of the second housing recess 184 toward the through hole 144 of the second front coupling part 143. In this case, by pushing the base portion 183a of the second coupler 183 toward the through-hole portion 144, the base portion 183a is sandwiched between the restricting portion 143c and the peripheral wall portion 143b, and the moving direction is restricted. Is done. Almost in synchronization with this, the tip of the base portion 183a hits the locking claw portion 143d. By further pressing the second coupler 183, the locking claw 143d is fitted into the locking hole 183c, and the second coupler 183 is hooked with respect to the second front side coupling part 143. In such a case, the entire operation portion 183b is accommodated in the second accommodation recess 184. Thereby, pulling operation is made difficult, ensuring the operativity of pushing operation of the operation part 183b.

  In addition, after performing the temporary fixing operation | work of the 2nd coupling tool 183 detailed above, it is also possible to perform the coupling | bonding operation | work of the 1st front side coupling | bond part 142 and the back side coupling | bond part 176 mentioned above. In such a case, it may be configured such that the first front side coupling portion 142 and the back side coupling portion 176 can be coupled by temporarily fixing the second coupling tool 183.

  Next, with reference to FIG. 43, the flow of work when releasing the fixed state of the front-side structure 101 and the back-side structure 102 in a state where the first front-side connection part 142 and the back-side connection part 176 are in the combined state. explain. 43 (a) to 43 (c) are explanatory views for explaining the flow of work when the fixed state between the front side structural body 101 and the back side structural body 102 is released.

  When releasing the fixed state between the front-side structure 101 and the back-side structure 102, as shown in FIG. 43A, the connection between the first front-side coupling portion 142 and the bulging portion 104 in the coupled state is performed. While cutting the part 145, the connection part 146 between the 1st front side coupling | joint part 142 which is in a coupling | bonding state, and the 2nd front side coupling | bond part 143 which is not in a coupling | bonding state is cut | disconnected with tools, such as a nipper and a cutter. Thereby, the separation of the front side structure 101 and the back side structure 102 is not hindered by the connection of the first front side coupling part 142 and the back side coupling part 176.

  In this case, the connecting portions 145 and 146 are provided with respect to the first front side coupling portion 142, and the back side coupling region 151 is not destroyed. Therefore, the first front side coupling portion 142 in the coupled state remains on the back side coupling region 151 side. Further, since the first front side coupling portion 142 in the coupled state remains in this way, the cover member 154 is fixed to the coupling region forming portion 152 through the coupling between the first front side coupling portion 142 and the back side coupling portion 176. The maintained state is maintained.

  Thereafter, as shown in FIG. 43 (b), by sliding and moving at least one of the front-side structure 101 or the back-side structure 102 in the direction restricted by the restriction means including the hook portion 111 and the locking receiver 121, the hook The locked state between the portion 111 and the locking receiver 121 is released. Thereafter, as shown in FIG. 43 (c), the front-side structure 101 and the back-side structure 102 are separated in the thickness direction of the substrate box 92, so that the structures 101 and 102 are completely separated. .

  In this case, since the connecting portion 145 is cut, it is possible to check whether or not the front-side structure 101 and the back-side structure 102 are separated by checking the cut portion of the connecting portion 145. Become.

  As described above, by releasing the fixed state of the two components 101 and 102, the main control board 91 and the CPU chip 93 can be exposed, and the main control board 91 and the CPU chip 93 can be inspected. . Both components 101 and 102 shown in the present embodiment can be re-boxed by separating the second front side coupling portion 143 and the back side coupling portion 176 after being separated.

  Here, an operation for re-fixing the two structural members 101 and 102 will be described with reference to FIGS. 40 (b), 41, 43 (d), and 43 (e). 43 (d) and 43 (e) are explanatory diagrams for explaining the flow of work when the front-side structure 101 and the back-side structure 102 are re-fixed. Based on the operation of FIG. 43 (d) → FIG. 43 (e), the second coupler 183 is shifted to the state of FIG. 41 → FIG. 40 (b).

  As shown in FIG. 43 (c), after separating both components 101 and 102 and inspecting the main control board 91 and the CPU chip 93, the components 101 and 102 are combined again (FIGS. 41 and 43 (d)). In this state, the through hole portion 144 of the second front side coupling portion 143 and the through hole portion 174 of the back side coupling portion 176 are in communication with each other. Here, as shown in FIG. 41 and FIG. 43 (d), the second coupler 183 temporarily fixed by the locking claw 143d is pushed into the back side structure 102 side, and FIG. 40 (b) and FIG. (e) (See FIG. 41 for the locking claw 143d). As shown in FIG. 40 (b), the second coupler 183 pushed in is hooked with the locking piece 168, and the second front coupling part 143 and the back coupling part 176 are coupled. Thereby, the re-fixation of both the structural bodies 101 and 102 is completed.

  Unlike the first front side coupling portion 142, the second front side coupling portion 143 is not provided with a portion that facilitates cutting corresponding to the connecting portions 145 and 146. For this reason, after the 2nd front side coupling | bond part 143 is couple | bonded, the cancellation | release of the coupling | bonding state is difficult.

  Note that the second front side coupling portion 143 may have a configuration corresponding to the coupling portions 145 and 146 and the like that is easily cut off in the same manner as the first front side coupling portion 142.

  Next, another fixing structure provided in the substrate box 92 will be briefly described.

  As shown in FIG. 30, an adhesive plate portion 191 is provided on the short side of the substrate box 92 opposite to the side where the front side binding region 141 and the back side binding region 151 are provided. The affixing plate part 191 is configured by superimposing an affixing plate part formed on the front-side component 101 and an affixing plate part formed on the back-side component 102. A seal seal 192 is attached to the sticking plate portion 191 so as to straddle the boundary between the two. When the seal seal 192 is peeled off after being stuck, the pressure-sensitive adhesive layer remains on the sticking plate portion 191 side, and re-sticking becomes impossible.

  A fixing portion 193 is provided on the short side portion of the substrate box 92 where the sticking plate portion 191 is provided so as to sandwich the sticking plate portion 191, and screws are fixed to the fixing portion 193. Thus, the front side structure 101 and the back side structure 102 are fixed.

  Further, in the present embodiment, a characteristic configuration is provided with respect to the restriction on the removal of the cover member 154 described above. Specifically, as removal restriction means for restricting removal of the cover member 154 from the back side structure 102, (1) the breaking screw 170, (2) a structure in which the cover member 154 is sandwiched by the both structures 101, 102 described above ( 3) A locking mechanism is provided, and (3) the locking mechanism has a characteristic configuration. Therefore, the locking mechanism and the configuration related thereto will be described in detail below with reference to FIGS. 30, 31, 37 and 44. FIG. 44 is a partial cross-sectional view taken along the line DD of FIG. In addition, since the concrete structure regarding (1) fracture | rupture screw 170 and (2) pinching structure has already been demonstrated, description here is abbreviate | omitted.

  As shown in FIG. 44, the locking mechanism 195 includes the structural body side locking portion 158 provided on the back side structural body 102 and the cover side locking portion 196 provided on the cover member 154 and hooked on the structural body side locking portion 158. And. Separation of the back side structural body 102 and the cover member 154 is restricted by the hooking portions 158 and 196 being hooked to each other.

  Referring to FIG. 30 again, the locking mechanisms 195 are provided on both sides of the cover member 154 sandwiching the cylindrical portion 178, that is, on both sides of the cover member 154 sandwiching the center. More specifically, they are disposed between the first front side coupling portion 142 and the second front side coupling portion 143, respectively. As described above, by disposing the locking mechanism 195 at the position sandwiched between the coupling portions 142 and 143, the displacement (for example, lifting) of the cover member 154 in the vicinity of the coupling portions 142 and 143 is suitably suppressed. ing. Since each of these locking mechanisms 195 has the same configuration, one locking mechanism 195 (the upper locking mechanism 195 in FIG. 30) will be described below, and the other locking mechanism (the lower side in FIG. 30). The description of the locking mechanism 195) will be omitted.

  As shown in FIGS. 31 and 44, the component-side locking portion 158 is formed by partitioning a part of the outer groove wall portion 157 of the back-side component 102 with respect to the peripheral portion. More specifically, the outer groove wall portion 157 is formed with a pair of cuts extending from the leading edge to the root side, and the component side locking portion 158 is configured using a portion sandwiched by the cuts. ing.

  The structural body side locking portion 158 includes an arm portion 197 that stands up from the flat surface portion 105 of the back side structural body 102. The arm portion 197 has a substantially plate shape parallel to the outer groove wall portion 157, and the distal end of the arm portion 197 is in contact with the first cover plate portion 172 of the cover member 154 in the same manner as the outer groove wall portion 157. And the latching claw part 198 which protrudes in the inner side groove wall part 156 side is integrally molded by the front end side of the arm part 197 (refer FIG. 44). More specifically, the locking claw portion 198 protrudes into the groove portion 155. In addition, although it was set as the structure which the front-end | tip of the structure side latching | locking part 158 (specifically arm part 197) contact | abuts to the 1st cover board part 172, you may provide a predetermined clearance gap between both, for example, both of them are It is also possible to adopt a close configuration.

  As described above, the structural body side locking portion 158 also has a function of restricting removal of the receiving member 153. Specifically, the receiving member 153 accommodated in the groove portion 155 has an outer facing plate portion in contact with the inner groove wall portion 156 and the plate surface of the arm portion 197, and an opposite inner facing plate portion 164. In a state where the inner groove wall portion 156 is in contact with the inner groove wall portion 156, that is, in a state where the attaching / detaching direction thereof is restricted, the removal of the groove portion 155 from the groove portion 155 is restricted by the catching claw portion 198 being caught by the locking recess portion 167. ing.

  Thus, in a state where the locking claw portion 198 is hooked with respect to the locking recess 167, the tip of the locking claw portion 198 protrudes into the recessed space 161 formed by the receiving member 153. More specifically, the locking claw portion 198 has a structural body side locking surface 198 a that comes into contact with the locking recess 167, and a part of the structural body side locking surface 198 a extends into the recessed space 161. I'm out.

  The cover side locking portion 196 of the cover member 154 is fitted in the recessed space 161. More specifically, the cover side locking portion 196 is disposed at a position facing the arm portion 197 across the outer facing plate portion of the receiving member 153. Further, the cover side locking portion 196 is disposed in a region sandwiched between the positioning protrusions 177. Thereby, it is possible to suppress the inconvenience that the relative position with respect to the structural body side locking portion 158 is shifted, and to secure the catching of both the locking portions 158 and 196.

The cover side locking portion 196 is integrally formed with the first cover plate portion 172.
An upright part 199 that rises from the cover plate part 172 is provided. The standing amount of the standing portion 199 is set equal to the standing amount of the positioning projection 177 from the first cover plate portion 172, that is, the depth dimension of the recessed space 161. For this reason, when the cover member 154 is mounted, the tip of the upright portion 199 is in contact with the bottom portion (specifically, the connecting plate portion 166) of the recessed space 161. It is also possible to adopt a configuration in which a predetermined gap is provided between the tip of the upright portion 199 and the connecting plate portion 166.

  The upright portion 199 has a substantially plate shape parallel to the arm portion 197, and a locking hole portion 200 that penetrates in the plate thickness direction of the upright portion 199 and fits the locking claw portion 198 is formed on the base side thereof. ing. A part of the inner peripheral surface of the locking hole 200 constitutes a cover side locking surface 200a that is hooked to the component side locking surface 198a, and the locking surfaces 198a, 200a are separated from each other by a slight gap. Facing each other (close to each other). When these locking surfaces 198a and 200a abut, removal of the cover member 154 is restricted. Further, each of the locking surfaces 198a and 200a has a planar shape orthogonal to the attaching / detaching direction of the cover member 154. For this reason, even when the cover member 154 is pulled in the disengagement direction, it is difficult for the inconvenience that the locking portions 158 and 196 are displaced along the locking surfaces 198a and 200a. In addition, it is good also as a structure which makes these both locking surfaces 198a and 200a contact each other in the state in which the cover member 154 was mounted | worn.

  Next, the structure which implement | achieves switching of the latching state of both the latching | locking parts 158 and 196 and a latch release state is demonstrated in detail.

  As shown in FIGS. 31 and 44, the outer surface of the arm portion 197 is formed to be recessed in a step shape from the outer surface of the outer groove wall portion 157. Specifically, the inner surface of the arm part 197 is located on the same plane as the inner surface of the outer groove wall part 157, and the thickness dimension of the arm part 197 is set smaller than the thickness dimension of the outer groove wall part 157. As a result, the steps described above are formed. For this reason, the outer surface of the outer groove wall portion 157 is in contact with the second cover plate portion 173 of the cover member 154 in almost the entire area thereof, whereas the outer surface of the arm portion 197 is opposed to the second cover plate portion 173. Thus, they face each other at a predetermined interval (gap). In other words, a closed space is defined between the arm part 197 and the second cover plate part 173 by mounting the cover member 154.

  The arm portion 197 is formed so as to facilitate bending deformation (elastic deformation) in a predetermined direction. Specifically, the thickness dimension is set to be smaller than the width dimension, that is, the length dimension in the longitudinal direction of the outer groove wall portion 157, toward the cover side locking portion 196 side and the second cover plate portion 173 side. This facilitates the bending deformation. However, the bending deformation of the arm portion 197 is suppressed by the outer groove wall portion 157 and the outer opposing plate portion of the receiving member 153, and is substantially bent toward the second cover plate portion 173, that is, the cover side locking portion. Only the bending deformation to the side away from 196 is allowed. In other words, the component side locking portion 158 is restricted so as to allow only bending deformation toward the second cover plate portion 173 side.

  As described above, a predetermined gap is secured between the component side locking portion 158 (specifically, the arm portion 197) and the second cover plate portion 173, and the arm portion toward the second cover plate portion 173 is provided. The bending deformation of 197 is allowed within the gap. In other words, when the arm portion 197 is bent and deformed toward the second cover plate portion 173, further bending deformation is suppressed by contacting the tip portion of the arm portion 197 and the second cover plate portion 173. More specifically, the distal end portion of the arm portion 197 contacts the root side of the second cover plate portion 173. Thereby, it is hard to produce the problem that the 2nd cover board part 173 bends by pushing on the arm part 197. FIG. The second cover plate portion 173 restricts the bending deformation of the arm portion 197, thereby avoiding the inconvenience that the arm portion 197 exceeds the elastic deformation limit and deforms to the plastic deformation region. Note that the second cover plate portion 173 is “a” which is restricted by the second cover plate portion 173 so that the deformation deformation of the structural body side locking portion 158 is restricted, that is, the displacement of the locking claw portion 198 is restricted. It can also be called a “regulator” or a “cover-side regulator”.

  Similarly, the cover side latching portion 196 is formed so as to be easily bent (elastically deformed) in a predetermined direction. Specifically, the plate thickness dimension of the upright portion 199 is smaller than the plate thickness dimension of the positioning projection 177, and a predetermined gap is secured between the inner facing plate portion 164 of the receiving member 153. .

  More specifically, the thickness dimension of the standing part 199 is set smaller than the width dimension of the standing part 199, that is, the length dimension in the longitudinal direction of the cover member 154, and the standing part of the cover member 154 in the longitudinal direction is set. While making the deformation deformation of 199 difficult, the deformation deformation to the component side locking portion 158 side (the second cover plate portion 173 side) and the inner groove wall portion 156 side (the inner facing plate portion 164 side of the receiving member 154) Has been made easier. As a result, the cover side locking portion 196, more specifically, the side on which the standing portion 199 bends is regulated so as to be substantially on the inner facing plate portion 164 side. In other words, in the cover side locking portion 196, bending deformation to the side opposite to the side where the deformation deformation in the component side locking portion 158 is allowed is allowed.

  When the cover side locking portion 196 is bent and deformed toward the inner facing plate portion 164, the cover side locking portion 196 and the inner facing plate portion 164 come into contact with each other, so that further bending deformation is avoided. Then, by restricting the deformation of the cover side locking portion 196 by the inner facing plate portion 164, inconvenience that the cover side locking portion 196 exceeds the elastic deformation limit to the plastic deformation region is avoided. Has been. If attention is paid to the point that the deformation of the cover side latching portion 196 is regulated by the inner facing plate portion 164, that is, the displacement of the latching hole portion 200 is regulated, the inner facing plate portion 164 is referred to as a “regulating portion”. Alternatively, it can also be referred to as a “constituent body side restricting portion”.

  Here, the relationship between the engaging margin of both the locking portions 158 and 196 (specifically, the locking surfaces 198a and 200a) and the amount of bending deformation of the both locking portions 158 and 196 will be described in detail with reference to FIGS. . FIG. 45A is a schematic view showing a state where the deformation deformation of the component side locking portion 158 is restricted, and FIG. 45B is a schematic view showing a state where the deformation deformation of the cover side locking portion 196 is restricted. FIG. 45 (c) is a schematic diagram showing a state in which the deformation deformation of both the structural body side locking portion 158 and the cover side locking portion 196 is restricted. In addition, the two-dot chain line shown in FIG. 44 shows a simplified state in which the respective locking portions 158 and 196 are bent and deformed.

  As described above, in the structural body side locking portion 158, the structural body side locking portion 158 is bent toward the second cover plate portion 173, so that the structural body side locking surface 198a is moved toward the second cover plate portion 173. Displace (move). As a result, the allowance for the locking surfaces 198a and 200a is reduced. Moreover, in the cover side latching | locking part 196, when the cover side latching | locking part 196 bends to the inner side opposing board part 164 side, the cover side latching surface 200a displaces (moves) to the inner side opposing board part 164 side. . As a result, the allowance for the locking surfaces 198a and 200a is reduced. In this embodiment, since the bending directions when releasing the hooks of the respective locking portions 158 and 196 are opposite to each other, the hooking margin for the cover side locking portion 196 of the component side locking portion 158 and the cover side engagement The hanging amount of the stopper 196 with respect to the component-side locking portion 158 is the same.

  Here, the amount of displacement of the component-side locking portion 158 (specifically, the component-side locking surface 198a) required to release the hooked state toward the second cover plate 173 side is also required to release the hooked state. The sum total of the displacement amount of the cover side latching portion 196 (specifically, the cover side latching surface 200a) toward the inner facing plate portion 164 side can be regarded as a margin for the latching portions 158 and 196. Hereinafter, the engagement allowance of both the locking portions 158 and 196 is referred to as “enclosure allowance X10”.

  As shown in FIG. 44, the displacement amount X11 of the component side locking surface 198a defined by the second cover plate portion 173, more specifically, the distal end portion of the component side locking portion 158 contacts the second cover plate portion 173. The displacement amount X11 (hereinafter referred to as the specified displacement amount X11) of the component side locking surface 198a in the state toward the second cover plate portion 173 is set to be smaller than the engagement allowance X10. For this reason, even if it deform | transforms until the front-end | tip of the structure side latching | locking part 158 contact | abuts on the 2nd cover board part 173, the catch of both the latching | locking parts 158 and 196 is maintained (refer Fig.45 (a)).

  Similarly, the gap dimension X12 between the second cover plate portion 173 and the structural body side locking portion 158 is also set smaller than the hook allowance X10. Thereby, for example, an intermediate portion of the component side locking portion 158 (specifically, a portion corresponding to the component side locking surface 198a) is pressed toward the second cover plate portion 173, and the displacement amount of the component side locking surface 198a is maximized. Even if the structural body side locking portion 158 is deformed so as to become, the catches of both the locking portions 158 and 196 are maintained.

  As shown in FIG. 44, the specified displacement amount X13 of the cover side locking surface 200a defined by the inner facing plate portion 164, more specifically, the tip of the cover side locking portion 196 abuts against the inner facing plate portion 164. A displacement amount X13 (hereinafter referred to as a prescribed displacement amount X13) of the cover side locking surface 200a toward the inner facing plate portion 164 in the state is set to be smaller than the engagement allowance X10. For this reason, even if it deform | transforms until the front-end | tip of the cover side latching | locking part 196 contacts the inner side opposing board part 164, the catch of both the latching | locking parts 158 and 196 is maintained (refer FIG.45 (b)).

  Similarly, the gap dimension X14 between the inner facing plate portion 164 and the cover side locking portion 196 is set to be smaller than the hooking allowance X10. Thereby, for example, an intermediate portion of the cover side locking portion 196 (specifically, a portion corresponding to the cover side locking surface 200a) is pressed toward the inner facing plate portion 164, and the displacement amount of the cover side locking surface 200a is maximized. Even if the cover side latching portion 196 is deformed as described above, the catches of both the latching portions 158 and 196 are maintained.

  The total sum of the specified displacement amount X11 of the component-side locking portion 158 and the specified displacement amount X13 of the cover-side locking portion 196 is set to be larger than the hanging allowance X10. For this reason, if the displacement amount of both the locking portions 158 and 196 reaches a specified value, more specifically, if the sum total of the displacement amounts of both the locking portions 158 and 196 exceeds the allowance X10, both the locking portions 158 and 158 The hooked state of 196 is released, and the removal of the cover member 154 is allowed (see FIG. 45C).

  As described above, the component side locking portion 158 has a function of restricting the removal of the receiving member 153 in addition to the hooking function with respect to the cover side locking portion 196. As described above, the function of regulating the removal of the receiving member 153 is that the displacement amount of the component side locking surface 198a reaches a specified value (specified displacement amount) X11 as shown in FIGS. 45 (a) and 45 (c). Thus, even if the structure side latching | locking part 158 bends, it becomes the structure maintained. Specifically, as shown in FIG. 44, the engagement allowance X15 between the component-side locking surface 198a of the component-side locking portion 158 and the locking recess 167 of the receiving member 153 is defined by the component-side locking surface 198a. It is set larger than the displacement amount X11. Thereby, in a state where the cover member 154 is mounted, the hooked state of the receiving member 153 is preferably maintained, and the positional deviation of the receiving member 153 can be suppressed. Note that the engagement allowance X15 is set to be larger than the maximum displacement amount (that is, the gap dimension X12) of the component side locking surface 198a. For this reason, even if it is a case where the structure side latching surface 198a is displaced maximum, the removal control function of the receiving member 153 will be maintained.

  Further, as shown in FIG. 44, the structural body side locking portion 158 has a structural body side guide portion 158a that bends both locking portions 158 and 196 away from each other as the cover member 154 moves in the mounting direction. Is formed. The structural body side guide portion 158a is continuous to the arm portion 197 and the locking claw portion 198, and has a planar shape that inclines so as to descend toward the recessed space 161 toward the mounting direction of the cover member 154. In addition, the component side guide portion 158 a overlaps a part of the tip of the cover side locking portion 196 in the mounting direction of the cover member 154.

  Further, a cover-side guide portion 199a corresponding to the component-side guide portion 158a is provided at a portion facing the component-side guide portion 158a at the tip of the cover-side locking portion 196. Specifically, the cover-side guide portion 199a is formed such that the tip end portion of the cover-side locking portion 196 is chamfered and substantially parallel to the component-side guide portion 158a. As a result, it is possible to suppress the support of both the guide portions 158a and 199a when they hit each other and promote smooth bending deformation. In addition, the guide portions 158a and 199a can suppress the unintentional deflection of the locking portions 158 and 196, and can guide the normal deflection deformation toward the predetermined side. .

  Next, the mounting operation of the cover member 154 will be described based on FIG. 46 (a) to 46 (d) are schematic diagrams showing a work flow when the cover member 154 is mounted. In mounting, FIG. 46 (a) → FIG. 46 (b) → FIG. 46 (c). ) → Operation is performed in the order of FIG.

  As shown in FIG. 46A, as a preparation stage for mounting the cover member 154, the receiving member 153 is first mounted in the groove portion 155. When performing this operation, the connecting plate portion 166 of the receiving member 153 comes into contact with the component-side guide portion 158a as the receiving member 153 is inserted into the groove portion 155. By pushing the structural body side guide portion 158 a into the depth of the groove portion 155, the structural body side locking portion 158 is bent and deformed away from the receiving member 153. Thereby, the protrusion amount into the groove part 155 of the latching claw part 198 decreases, and the movement to the mounting completion position of the receiving member 153 is permitted. Thus, when the structure side latching | locking part 158 deform | transforms and deform | transforms, mounting | wearing with the cover member 154 has not yet been performed and the restriction | limiting of bending deformation by the 2nd cover board part 173 is not implemented. For this reason, the structure side latching | locking part 158 can be bent greatly to such an extent that the movement into the groove part 155 of the receiving member 153 is accept | permitted.

  As the receiving member 153 reaches the predetermined mounting completion position, the structural body side locking portion 158 returns to the original state. Then, the locking claw portion 198 is caught on the locking recess 167. Thereby, mounting | wearing of the receiving member 153 is completed and removal of the receiving member 153 is controlled.

Next, as shown in FIG. 46B, the cover member 154 is pushed in so that the positioning projection 177 of the cover member 154 fits into the recessed space 161 of the receiving member 153. By inserting the positioning projection 177 into the recessed space 161, the mounting direction of the cover member 154 is defined. Further, the rising amount of the standing portion 199 is set smaller than the rising amount of the second cover plate portion 173 from the first cover plate portion 172. For this reason, the 2nd cover board part 173 will contact the outer side groove wall part 157 prior to inserting the standing part 199 in the hollow space 161. By inserting the second cover plate portion 173 along the outer groove wall portion 157, the displacement of the cover member 154 is suppressed, and the relative position between the positioning projection 177 and the recessed space 161 is not visually confirmed. The above-described insertion operation can be performed.

  Thus, in a state where the insertion direction of the cover member 154 is defined, the cover-side guide portion 199a of the cover-side locking portion 196 is pushed into the component-side guide portion 158a of the structure-side locking portion 158 by pushing the cover member 154. To touch. In such a state, the second cover plate portion 173 is opposed to the outer groove wall portion 157 (specifically, in contact). More specifically, the second cover plate portion 173 is opposed to the distal end portion of the component side locking portion 158. Thereby, the bending of the same structure side latching | locking part 158 can be controlled.

  When the cover member 154 is further pushed in from the state shown in FIG. 46B, the component side guide portion 158a is pushed by the cover side locking portion 196 (specifically, the cover side guide portion 199a), and the component side locking portion 158 is The second cover plate portion 173 is bent and deformed. In synchronization with this, the cover-side guide portion 199a slides on the component-side guide portion 158a, and the cover-side locking portion 196 is bent and deformed toward the inner facing plate portion 164 side of the receiving member 153. Then, when the total amount of bending of both the locking portions 158 and 196 exceeds a predetermined amount, the locking claw portion 198 rides on the plate surface of the upright portion 199, and the cover member 154 moves to the mounting completion position. Is allowed (see FIG. 46C).

  In this state, when the cover member 154 is allowed to move to the mounting completion position, the cover claw 198 reaches the lock hole 200 by further pressing the cover member 154. Along with this, both the locking portions 158 and 196 are restored to their original state by their own elastic force, and the locking claw portion 198 is fitted into the locking hole portion 200 as shown in FIG. Almost in synchronization with this, the cover member 154 reaches the mounting completion position, and the removal of the cover member 154 is restricted.

  Next, the electrical configuration of the pachinko machine 10 will be described based on the block diagram of FIG. In FIG. 44, the power supply line is indicated by a double arrow, and the signal line is indicated by a solid arrow.

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.

  In the board box 92 of the main control device 63, the front side coupling part 142 and the back side coupling part 176 are coupled by the coupling tool 181, so that the separation of the front side structural body 101 and the back side structural body 102 is prevented. In this case, since the receiving member 153 that locks the coupling tool 181 in the back side structure 102 is made of metal, even if the locking portion between the receiving member 153 and the coupling tool 181 is broken to try to release the locking. It becomes difficult to do. In this configuration, the receiving member 153 is provided across all the back side coupling portions 176. Thereby, compared with the structure which installs the receiving member 153 with respect to each of each back side coupling | bond part 176, the formation operation | work of the board | substrate box 92 can be performed favorably. Further, the number of members of the receiving member 153 can be reduced as compared with the configuration in which the receiving member is individually installed for each of the back side coupling portions 176.

  Since the metal receiving member 153 is provided over substantially the entire length of the predetermined peripheral surface portion of the substrate box 92, the predetermined peripheral surface portion is broken to the internal space of the substrate box 92. It is possible to prevent the act of illegally forming the opening that leads to it. In addition, since the receiving member 153 constituting the fixing means fulfills the function of preventing the illegal act, the receiving member 153 can be multi-functional.

  The receiving member 153 includes a series of recessed spaces 161 formed with a width direction defined by a pair of opposing plate portions 164 and 165 facing each other, and a locking portion 158 corresponding to each back side coupling portion 176. Is formed in the recessed space 161. The locking with the coupler 181 is performed in the recessed space 161. That is, the locking portion of the coupler 181 is performed in the recessed space 161 defined by the metal receiving member 153. Therefore, even if it is attempted to release the locked state by destroying the surroundings of the locked portion, it becomes difficult to do so, and it is possible to prevent such illegal acts. In addition, the above-described excellent effect can be obtained for each back-side coupling portion 176 by a relatively simple configuration in which a plurality of locking portions 158 are provided in the series of recessed spaces 161.

  In addition, a pair of opposed plate portions 164 and 165 that form the recessed space 161 are provided so as to be located over substantially the entire length of a predetermined peripheral surface portion of the substrate box 92. Therefore, compared to the configuration in which one plate portion is provided, the strength of the predetermined peripheral surface portion is increased, and the predetermined peripheral surface portion is destroyed and attempts to illegally form an opening leading to the internal space of the substrate box 92 Can be prevented.

  The back side structure 102 is provided with a cover member 154 that divides the entrance of the recessed space 161 of the receiving member 153 into a plurality of openings and forms a plurality of back side coupling portions 176. As a result, even if the metal receiving member 153 is not provided with a portion that divides the entrance of the recessed space 161 into a plurality of openings, the function of partitioning is performed by the cover member 154. Thereby, the shape of the receiving member 153 can be simplified. In particular, since the cover member 154 is made of synthetic resin, a portion having a complicated shape in the back side coupling portion 176 is formed with the cover member 154 made of synthetic resin, and a portion for locking the coupler 181 is made of metal. The back side coupling portions 176 can be formed satisfactorily.

  Further, in the configuration in which the receiving member is individually installed for each of the four back side coupling portions 176, at least four members to be installed in the coupling region forming portion 152 of the back side structure 102 are required. In the configuration of the pachinko machine 10 provided with the receiving member 153 provided over the connecting portion 176 and the cover member 154 that covers the receiving member 153, the number of members installed in the connecting region forming portion 152 is two. . That is, in a configuration in which three or more back side coupling portions 176 are provided, even if the cover member 154 is provided separately from the back side configuration body 102, the receiving member is individually provided for each of the back side coupling portions 176. The number of members can be reduced as compared with the conventional configuration in which the is installed. Accordingly, it is possible to reduce the number of work steps for forming the back side coupling region 151 in the back side structure 102 as compared with the conventional structure.

  Further, instead of providing the cover member 154 separately from the backside structure 102, a configuration in which the function of the cover member 154 is integrally formed with the backside structure 102 is also conceivable. In this case, the backside structure 102 is also possible. There is a concern that the function of covering the periphery of the receiving member 153 and preventing unauthorized access to the receiving member 153 may deteriorate due to the structure of the mold for molding the mold. On the other hand, by providing the cover member 154 separately from the back-side structure 102, the function of preventing the unauthorized access is enhanced, and as described above, the back-side coupling region is compared with the conventional structure. Reduction in the number of members and the number of work steps in forming 151 can be achieved.

  By forming the partition wall portion 175 on the cover member 154, the arrangement of the corresponding front side coupling portion 142 to the back side coupling portion 176 is guided by the partition wall portion 175, and the arrangement can be performed favorably. Further, according to this configuration, the cover member 154 having a function of partitioning the entrance of the recessed space 161 into a plurality of openings functions as a guide portion, so that the cover member 154 can be multifunctional.

  The receiving member 153 is installed with respect to the coupling region forming part 152 of the back side structure 102 after completion. For example, a configuration in which the receiving member 153 is insert-molded when the back-side structure 102 is formed is conceivable. In this case, it is possible to make unauthorized removal of the receiving member difficult, but the mold is complicated. It is unfavorable because it invites. In addition, if the receiving member 153 provided separately is inserted into the back-side structure 102 (groove portion 155) after completion, the mold can be simplified as compared with the case where the above-described insert molding is performed. However, there is a concern that unauthorized removal of the receiving member 153 is likely to be performed. If the removal of the receiving member 153 becomes easy in this way, the substrate box 92 is easily opened illegally, or the imprint of the substrate box 92 is easily concealed by crafting the receiving member 153. From the viewpoint of crime prevention.

  On the other hand, in the present embodiment, the receiving member 153 is installed with respect to the coupling region forming portion 152 of the backside structure 102, and removal from the groove portion 155 is restricted by the cover member 154. Thereby, it is possible to suppress unauthorized removal of the receiving member 153 while suppressing complication of the manufacturing process (mold). Therefore, it is possible to contribute to the suppression of fraud performed on the board box 92 while enabling the board box 92 to be formed satisfactorily.

  Further, a fixing portion of the receiving member 153 with respect to the coupling region forming portion 152 is covered with a cover member 154. As a result, in the configuration in which the receiving member 154 is installed on the back-side structure 102 after completion, it is possible to make it difficult to perform an act of illegally releasing the fixed state of the receiving member 153 with respect to the back-side structure 102. Become. Further, according to this configuration, the cover member 154 having a function of partitioning the entrance of the recessed space 161 into a plurality of openings functions to cover the fixing portion of the receiving member 153 with respect to the coupling region forming portion 152, and thus the cover member Multi-function of 154 is achieved.

  The second coupler 183 is configured to be accommodated in the second accommodating recess 184 by being temporarily fixed. In this way, by keeping the second coupler 183 in a ready state for coupling, loss of the second coupler 183 can be easily avoided. In addition, although the second coupling tool 183 can be easily pushed in the coupling direction, the entire operation portion 183b is fitted in the second accommodating recess 184, and therefore the removal (pulling) operation is difficult. ing. Thereby, unauthorized removal of the second coupler 183 is suppressed.

  In addition, when one receiving member 153 is partitioned by the cover member 154, the receiving member 153 (particularly, the locking corresponding to the other through-hole portion 144 is provided through the through-hole portions 144 formed in the front side coupling portions 142 and 143. There is a risk of unauthorized access to the piece 168). In this regard, the through-hole portion 144 in the present embodiment is closed in advance by both the couplers 181 and 183. Specifically, the through-hole portion 144 of the second front side coupling portion 143 is blocked by the second coupling tool 183 temporarily fixed. For this reason, even if it is the structure where the receiving member 153 and the cover member 154 are each provided over a some coupling | bond part, suppressing the deterioration of crime prevention resulting from having employ | adopted such a structure suitably Can do. In addition, unauthorized access to the fracture screw 170 through the through-hole portion 144 can be suppressed.

  By destroying the connecting portions 145 and 146, it is possible to separate the front-side structure 101 and the back-side structure 102 while maintaining the connected state of the connecting portions 142 and 176 using the connecting tool 181. In addition, it is possible to leave a trace when separating the front-side structure 101 and the back-side structure 102 while firmly fixing using the coupler 181. In this case, the connecting portion 145 is provided with respect to the first front side coupling portion 142. For example, assuming a configuration in which the connecting portions 145 and 146 are provided with respect to the back side coupling portion 176, the front side structure 101 and the back side structure 102 can be separated only by destroying the connecting portions 145 and 146. It is assumed that the receiving member 153 needs to be further broken. If it does so, isolation | separation operation of the front side structure 101 and the back side structure 102 cannot be performed easily. On the other hand, since the connecting portions 145 and 146 are provided with respect to the first front-side coupling portion 142, the above-described inconvenience does not occur, and the separation operation between the front-side structure 101 and the back-side structure 102 is performed. Can be easily performed.

  The cover member 154 includes a receiving plate portion 185. When the front side structure 101 and the back side structure 102 are combined, the frame portion 112 of the front side structure 101, the peripheral edge of the main control board 91, and the back side structure 102 are provided. The support plate portion 185 holds the receiving plate portion 185. Thereby, the cover member 154 can be held at the installation location in a more stable state.

  With the attachment of the cover member 154, the cover-side locking portion 196 of the cover member 154 and the component-side locking portion 158 of the back-side component 102 are hooked and the removal of the cover member 154 is restricted. Thereby, complication of the removal regulation work of cover member 154 can be controlled.

These locking portions 158 and 196 are disposed between the respective back side coupling portions 176 corresponding to the first front side coupling portion 142 and the second front side coupling portion 143. Thereby, the position shift of the cover member 154 in those back side coupling | bond parts 176 is suppressed suitably. For this reason, when the couplers 181 and 183 are inserted, it is difficult to cause inconvenience that the back-side coupler 176 and the couplers 181 and 183 support. Therefore, the couplers 181 and 183 can easily reach the locking piece 168 of the receiving member 153.

  Both the structure-side latching portion 158 and the cover-side latching portion 196 are bent and deformed, and the total amount of these deformations (specifically, the total amount of displacement of the locking surfaces 198a and 200a) exceeds the allowance X10. Thus, the hooked state by the both locking portions 158 and 196 is released. In other words, even if any one of the locking portions 158 and 196 is bent, the locked state cannot be released. As a result, it is possible to make an unauthorized release operation of the locked state difficult. For example, even if the fraudster tries to perform the unlocking operation alone, the component side locking portion 158 is bent with one hand while the cover side locking portion 196 is bent with the other hand, Furthermore, it is necessary to perform the pulling-out operation of the cover member 154, and it is difficult to perform all the operations alone. Therefore, unauthorized removal of the cover member 154 is suppressed as described above.

  The deformation deformation of the structural body side locking portion 158, that is, the displacement of the structural body side locking surface 198 a is restricted by the second cover plate portion 173. More specifically, the maximum deflection amount of the component side locking portion 158, that is, the maximum displacement amount of the component side locking surface 198a is provided between the component side locking portion 158 and the second cover plate portion 173. It is defined based on the gap size. For this reason, it is hard to produce the problem that only the structure side latching | locking part 158 deform | transforms excessively and a latching state is cancelled | released.

  Similarly, the maximum deflection amount of the cover side locking portion 196, that is, the maximum displacement amount of the cover side locking surface 200 a is the same between the cover side locking portion 196 and the inner opposing plate portion 164 of the receiving member 153. It is defined based on the gap size. For this reason, only the cover side latching | locking part 196 is deform | transformed excessively, and it is hard to produce the problem that a latching state is cancelled | released.

  As described in detail above, since the second cover plate portion 173 and the inner facing plate portion 164 are provided, even when only one of the locking portions 158 and 196 is bent and deformed, the locked state is released. There is no. Thereby, the illegal cancellation | release of a latching state can be avoided suitably.

  When the structural body side locking portion 158 is bent and deformed, the bending deformation is restricted by the tip of the structural body side locking portion 158 coming into contact with the base side of the second cover plate portion 173. In this way, by suppressing the deformation of the component side locking portion 158 on the base side of the second cover plate portion 173, it is possible to suppress the second cover plate portion 173 from being bent together with the component side locking portion 158. Thereby, the function as a stopper part in the 2nd cover board part 173 can be made suitable. The same applies to the cover side locking portion 196. Specifically, when the cover side latching portion 196 is bent and deformed, the tip end portion of the cover side latching portion 196 hits the root side of the inner facing plate portion 164 (specifically, the root side of the inner groove wall portion 156). Deformation is regulated. In this way, by suppressing the deformation of the cover side locking portion 196 on the base side of the inner facing plate portion 164, it is possible to suppress the bending of the inner facing plate portion 164 together with the cover side locking portion 196. Thereby, the excessive bending deformation of the cover side latching | locking part 196 is suppressed suitably.

  Each of the locking portions 158 and 196 is disposed in a region sandwiched between the second cover plate portion 173 and the inner facing plate portion 164. This makes it difficult to bend each of the locking portions 158 and 196 with a finger or the like. More specifically, it is arranged in an area defined by the cover member 154 and the back side structure 102. For this reason, exposure of each latching | locking part 158,196 is suppressed, and it is easy to avoid making unauthorized access (physical contact) with respect to these latching | locking part 158,196.

  The second cover plate part 173 is in contact with the outer groove wall part 157 and the flat part 105 on both sides and the base side of the structural body side locking part 158. For this reason, even if an external force directed inward of the substrate box 92 is applied to the second cover plate portion 173, such external force is dispersed by the outer groove wall portion 157 and the flat portion 105. It is difficult for the structure side locking portion 158 to be affected.

  The latching claw portion 198 of the structural body side latching portion 158 is hooked on the latching recess 167 of the receiving member 153, so that the removal of the receiving member 153 from the backside structural body 102 is restricted. That is, the component side locking portion 158 has a function of regulating removal of the receiving member 153 in addition to a function of regulating removal of the cover member 154. Thereby, the multi-function of the structure side latching | locking part 158 is implement | achieved.

  More specifically, when the receiving member 153 is attached, the cover member 154 is not attached. For this reason, the deformation deformation of the structural body side locking portion 158 is not restricted by the second cover plate portion 173. The receiving member 153 is bent and deformed so as to allow movement of the receiving member 153 toward the back side of the groove portion 155. On the other hand, after the cover member 154 is mounted, the bending deformation of the structural body side locking portion 158 is restricted by the second cover plate portion 173, and the removal restriction of the receiving member 153 is maintained even when it is deformed to the maximum. Is done. As a result, it is possible to make the removal after mounting the cover member 154 more difficult while realizing simplification of the mounting operation of the receiving member 153. In particular, it is possible to prevent the receiving member 153 from being displaced due to the mounting of the cover member 154, which can contribute to the realization of a practically preferable configuration.

  A second cover plate portion 173 as a “stopper portion” corresponding to the structural body side locking portion 158 is provided on the cover member 154 side, and is opposed to the inside as a “stopper portion” corresponding to the cover side locking portion 196. A plate portion 164 is provided on the back side structure 102 side. Thereby, due to the displacement of the cover member 154 and the like, it is difficult to cause the inconvenience that the unlocking of both the locking portions 158 and 196 is realized based only on the bending deformation of the one locking portion 158 and 196. can do. More specifically, if the cover member 154 is displaced to the side where the gap between the second cover plate portion 173 of the cover member 154 and the component side locking portion 158 is widened, the cover side locking portion 196 is The position shifts to the side where the allowance with the structural body side locking portion 158 increases. That is, the allowance for the cover side locking portion 196 and the structure side locking portion 158 increases corresponding to the widening of the gap between the structure side locking portion 158 and the second cover plate portion 173. In addition, if the cover member 154 is displaced to the side where the engagement margin between the cover side latching portion 196 and the component side latching portion 158 is reduced, the second cover plate portion 173 is connected to the component side latching portion 158. It will be displaced to the side where the gap dimension is narrowed. In other words, the clearance between the component-side locking portion 158 and the second cover plate portion 173 is narrowed corresponding to the reduction in the allowance between the component-side locking portion 158 and the cover-side locking portion 196. Thereby, it is possible to suppress the balance between the engagement allowance and the gap dimension from being extremely collapsed due to the positional deviation, and to make it difficult to easily release the locked state.

  Further, in a state where the cover member 154 is mounted, the tip end portion of the component side locking portion 158 is in contact with the plate surface of the first cover plate portion 172 of the cover member 154. As described above, the structural body side locking portion 158 and the first cover plate portion 172 are brought into contact with each other, whereby the deformation deformation of the structural body side locking portion 158 in the state where the cover member 154 is mounted can be suppressed. When the cover member 154 is completely attached, the front end of the cover side locking portion 196 is in contact with the connecting plate portion 166 of the receiving member 153. For this reason, the deformation on the cover side locking portion 196 is similarly suppressed.

  The side that bends when the structure-side latching portion 158 is unlocked and the side that bends when the cover-side latching portion 196 is unlocked are reversed. As a result, it is possible to easily secure the allowance for both the locking portions 158 and 196 while narrowing the operating range when the both locking portions 158 and 196 are bent and deformed. Therefore, it is possible to suppress the occurrence of inconvenience that the catching mechanism is not sufficiently performed while suppressing the expansion of the installation area of the locking mechanism 195. If the locking mechanism 195 is increased in size, it is not preferable because the operation range and the allowance can be easily secured, but the substrate box 92 is increased in size. In this regard, if it is possible to contribute to the downsizing of the locking mechanism 195 while securing the catching function as described above, it is possible to suppress the increase in the size of the substrate box 92, and the technical contribution becomes large.

  The cover member 154 is made of a transparent resin material. As a result, even when the cover member 154 is completely attached, the state of the locking portions 158 and 196 can be visually confirmed from the outside of the board box 92 without removing the cover member 154. This contributes to the efficiency of confirmation work.

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

  (1) In the above-described embodiment, the structure-side latching portion 158 has the latching claw portion 198 and the cover-side latching portion 196 has the latching hole portion 200, but this is changed as follows. It is also possible to do. For example, it is good also as a structure in which the structure side latching | locking part 158 has a latching hole part and the cover side latching | locking part 196 has a latching claw part. Moreover, it is good also as a structure which both the latching | locking parts 158 and 196 each have a latching claw part, and these latching claw parts mutually hook.

  (2) In the said Example, it was set as the structure by which the latching state of these latching | locking parts 158 and 196 is cancelled | released when the structure side latching | locking part 158 and the cover side latching | locking part 196 bend and deform | transform to the opposite side. However, the bending side of each of the locking portions 158 and 196 is not limited to the “reverse side”.

  Hereinafter, a modification will be described with reference to FIG. 48 (a) is a schematic view showing the structural body side locking portion and the cover side locking portion, and FIGS. 48 (b) to 48 (d) show both locking portions as viewed from the attaching / detaching direction of the cover member. FIG. 48 (e) is an explanatory view showing a state where the both locking portions are released when viewed from the attaching / detaching direction of the cover member. In addition, since it has the structure substantially the same as the structure side latching | locking part 158 mentioned above regarding the structure side latching | locking part, detailed description is abbreviate | omitted.

  As shown in FIG. 48A, the cover side locking portion 231 of the cover member 230 is located on the side of the structural body side locking portion 158 in the recessed space 161 of the receiving member 153 (specifically, the upper peripheral wall of the back side structural body 102). And the arm portion 234 that stands on the flat surface portion 105 side of the back-side component 102 from the first cover plate portion 232. The arm portion 234 has a plate shape, and the plate surface faces the longitudinal direction of the cover member 230. As described above, the arm portion 234 has a plate shape, so that bending deformation toward the upper peripheral wall portion 122 is facilitated. Further, the width dimension of the arm portion 234 is set to be approximately equal to the gap dimension between the opposing plate portions 164 and 165 in the recessed space 161, and the bending deformation toward the opposing plate portions 164 and 165 is suppressed.

  On the distal end side of the arm portion 234, a cover side locking claw portion 235 that is hooked on the locking claw portion 198 of the component side locking portion 158 is formed. More specifically, the cover-side latching claw portion 235 protrudes from the plate surface on the side facing the component-side latching portion 158 in the arm portion 234. The cover-side latching claw 235 has a cover-side latching surface 235a that faces the component-side latching surface 198a of the latching claw 198. Removal of the cover member 230 from the structural body 102 is restricted.

  The cover side locking portion 231 (specifically, the arm portion 234) is bent and deformed toward the upper peripheral wall portion 122 of the back side structure 102, whereby the cover side locking surface 235a is displaced to the side away from the structure side locking surface 198a. In this case, the allowance between the cover side locking surface 235a and the component side locking surface 198a is reduced.

  Further, a stopper portion 237 for restricting the deformation of the cover side locking portion 231 is formed on the side opposite to the side where the cover side locking claw portion 235 is formed in the arm portion 234 (that is, the upper peripheral wall portion 122 side). ing. The stopper portion 237 is formed by cutting and raising a part of the outer facing plate portion of the receiving member 153, and has a plate shape standing from the outer facing plate portion. The stopper portion 237 faces the arm portion 234 at a predetermined interval, and when the cover side locking portion 231 is bent, the end portion of the stopper portion 237 comes into contact with the plate surface of the arm portion 234, so that The bending deformation of is regulated.

  Here, with reference to FIG. 48 (b) to FIG. 48 (d), the engagement allowance of both the locking surfaces 198a and 235a will be described. As shown in FIG. 48 (b), in a state in which both the locking portions 158 and 231 are hooked, the structure on the cover side locking portion 231 side of the component side locking surface 198a and the configuration on the cover side locking surface 235a. The half on the body side locking portion 158 side overlaps with each other in the attaching / detaching direction of the cover member 230. The structural body side locking surface 198a has a substantially rectangular shape as a whole, and a structural body side cut-out edge 238 is formed at a corner on the cover side locking portion 231 side and on the opposite side to the side on which it is bent. ing. On the other hand, the cover-side locking surface 235a is also substantially rectangular as a whole, and the structure-side notch edge is formed at the corner on the structure-side locking portion 158 side and the side opposite to the side on which it is bent. A cover-side notch edge 239 parallel to the portion 238 is formed.

  As shown in FIG. 48 (c), when the structural body side locking portion 158 is bent and deformed and the structural body side locking surface 198a is displaced to the second cover plate portion 233 side, the engagement margin between the both locking surfaces 198a and 235a. However, a part of both the locking surfaces 198a and 235a is maintained in an overlapped state. Specifically, a part of the structure-side cut-out edge 238 is maintained in a state where it overlaps the cover-side locking surface 235a. For this reason, the hooked state of both the locking portions 158 and 231 is suitably maintained.

  In addition, the displacement amount of the structural body side locking surface 198a in this different example, that is, the specified displacement amount and the maximum displacement amount defined by the second cover plate portion 173 are substantially equal. FIG. 48C shows the relative relationship when the maximum displacement occurs, but the same relative relationship is maintained even when the specified displacement occurs. That is, a part of the structure-side notch edge 238 is maintained in a state where it overlaps the cover-side locking surface 235a.

  In such a state where the allowance is reduced, the remaining allowance, specifically, the allowance in the bending direction of the cover side engaging portion 231 is smaller than the specified displacement amount and the maximum displacement amount of the cover side engaging surface 235a. Yes.

  In addition, as shown in FIG. 48 (d), when the cover side locking portion 231 is bent and deformed and the cover side locking surface 235a is displaced toward the stopper portion 237, the amount of engagement between the locking surfaces 198a and 235a is as follows. Although decreasing, a part of both the locking surfaces 198a and 235a is maintained in an overlapping state. Specifically, a part of the cover-side notch edge 239 is maintained in a state where it overlaps the component-side locking surface 198a. For this reason, the hooked state of both the locking portions 158 and 231 is suitably maintained.

  In addition, the displacement amount of the cover side locking surface 235a in this different example, that is, the specified displacement amount and the maximum displacement amount defined by the stopper portion 237 are substantially equal. FIG. 48C shows the relative relationship when the maximum displacement occurs, but the same relative relationship is maintained even when the specified displacement occurs. That is, a part of the cover-side notch edge 239 is maintained in a state where it overlaps the component-side locking surface 198a.

  In this state where the allowance is reduced, the remaining allowance, more specifically, the allowance in the bending direction of the component side locking portion 158 is smaller than the prescribed displacement amount and the maximum displacement amount of the component side engaging surface 198a. Yes.

  Here, when the cover side locking surface 235a is displaced from the state of FIG. 48 (c), or when the structural body side locking surface 198a is displaced from the state of FIG. 48 (d), as shown in FIG. 48 (e). In addition, the engagement allowance of both the locking surfaces 198a and 235a is zero. That is, when the component side locking surface 198a is displaced toward the second cover plate portion 233 and the cover side locking surface 235a is displaced toward the stopper portion 237, the locking surfaces 198a and 235a are caught. The state is released.

  In addition, the cover side latching | locking part 231 is each formed with the guide part 241 similar to the guide part 158a shown in the said Example. As the cover member 230 is moved to the mounting position, the guide portions 158a and 241 come into contact with each other, and the deformation of the locking portions 158 and 231 is realized.

  (3) In the above embodiment, the locking portions 158 and 196 themselves are flexibly deformed (elastically deformed) to switch between the locked state and the unlocked state, but this is changed as follows. May be. In other words, the locking portions 158 and 196 are movably provided, and the locking portions 158 and 196 are moved while the bending portions of the separately provided member (biasing member) are deformed. Switching to the stop release state may be performed.

  A specific example will be described below with reference to FIG. The structure-side locking portion 251 is provided separately from the back-side structure 102. A shaft portion 252 extending in the same direction as the longitudinal direction of the cover member 154 is integrally formed at the end portion of the structural body side locking portion 251 on the flat surface portion 105 side. A bearing hole portion 253 into which the shaft portion 252 is fitted is formed in the outer groove wall portion 157 of the back side structure 102, and the shaft portion is inserted into the bearing hole portion 253. Thereby, the structure side latching | locking part 251 is in the state supported by the back side structure 102 so that rotation was possible.

  A leaf spring 255 is provided between the structural body side locking portion 251 and the second cover plate portion 173. The leaf spring 255 has a main body portion 256 parallel to the second cover plate portion 173, and the main body portion 256 is bonded to the second cover plate portion 173. Thereby, the leaf spring 255 is integrated with the cover member 154.

  The leaf spring 255 has a bent portion 257 protruding toward the component side locking portion 251, and the tip of the bent portion 257 contacts the component side locking portion 251 (more specifically, the arm portion 258). ing. Note that the protruding amount of the bent portion 257 from the main body portion 256 is set to be slightly larger than the gap dimension between the component side locking portion 251 and the second cover plate portion 173. Thereby, in the state in which the bending part 257 contacted the structure side latching | locking part 251, the structure side latching | locking part 251 is the state urged | biased by the cover side latching | locking part 196 side.

  When the cover member 154 is attached to the back-side component 102, the cover-side latching portion 196 and the component-side latching portion 251 come into contact with each other, so that the component-side latching portion 251 is on the second cover plate portion 173 side. To turn. In this case, the bent portion 257 is folded, and the component side locking portion 251 is biased toward the inner groove wall portion 156 side. When the cover member 154 moves to the predetermined mounting completion position, the locking claw portion 259 of the component side locking portion 251 reaches a position where it can be fitted into the locking hole portion 200 of the cover side locking portion 196. The structural body side locking portion 251 is rotated by the urging force of the leaf spring 255 and returns to the original position. Thereby, the latching claw part 259 fits into the latching hole part 200, and both are caught.

  As described in detail above, the leaf spring 255 is elastically deformed, so that switching between the locked state and the unlocked state can be realized. A coil spring can be used instead of the plate spring 255.

  (4) In the above-described embodiment, the inner opposing plate portion 164 as a “first stopper portion” that restricts the deformation of the cover side locking portion 196 is provided on the back side structure 102 side, and the structure side locking portion 158 is bent. The second cover plate portion 173 serving as the “second stopper portion” that restricts deformation is provided on the cover member 154 side. However, this is changed, and the “first stopper portion” is provided on the cover member 154 side. A “stopper portion” may be provided on the back side structure 102 side.

  For example, as shown in FIG. 49B, a cover-side stopper portion 271 that restricts the deformation of the cover-side locking portion 196 is integrally formed on the cover member 154, and the component-side locking portion 158 is formed on the back-side structure 102. It is good to form the structure side stopper part 272 which controls bending deformation. More specifically, the cover-side stopper portion 271 is formed so as to face the cover-side locking portion 196 with a predetermined gap, and the component-side stopper portion 272 is fixed to the component-side locking portion 158 with a predetermined amount. It is good to form so as to confront each other with a gap.

  (5) In the said Example, although the outer side groove wall part 157 in the back side structure 102 was comprised by the structure side latching | locking part 158, it is not limited to this. For example, the structure-side locking portion 158 can be formed separately from the outer groove wall portion 157 independently.

  (6) In the above-described embodiment, the front end portions of the locking portions 158 and 196 contact the inner facing plate portion 164 as the “first stopper portion” and the second cover plate portion 173 as the “second stopper portion”. Although the restriction of the bending of each locking portion 158, 196 was performed, this was changed, and the portions other than the tip portion in each locking portion 158, 196 hit the inner facing plate portion 164 and the second cover plate portion 173. You may regulate bending.

  Further, the inner facing plate portion 164 and the second cover plate portion 173 are each formed in a plate shape, but is not limited thereto. In other words, the “first stopper portion” and the “second stopper portion” do not have to be plate-shaped as long as the bending deformation of the locking portions 158 and 196 can be restricted. For example, the “first stopper portion” and the “second stopper portion” can be configured by a protrusion or the like that protrudes from the cover member 154 or the back side structure 102. The “first stopper portion” and the “second stopper portion” do not necessarily have to be integrally formed with the cover member 154 and the back side structure 102, and members formed separately are attached to the cover member 154 and the back side structure 102. It may be attached.

  (7) In the above-described embodiment, the structure-side locking portion 158 is provided with the structure-side guide portion 158a and the cover-side locking portion 196 is provided with the cover-side guide portion 199a. However, the present invention is not limited to this. What is necessary is just to set it as the structure which provides a guide part in at least one. In addition, although each guide part 158a, 199a was integrally molded with respect to each locking part 158, 196, this may be changed and each guide part 158a, 199a may be provided separately for each locking part 158, 196. .

  (8) In the above embodiment, the cover side locking portion 196 is subjected to the bending deformation and restricted by the inner facing plate portion 164 of the member 153. More specifically, the cover side locking portion 196 is configured to contact the inner facing plate portion 164 supported by the inner groove wall portion 156 of the back side structure 102. It is also possible to change this as follows. That is, it is also possible to adopt a configuration in which the cover side locking portion 196 directly contacts the inner groove wall portion 156 without the inner facing plate portion 164 being interposed.

  (9) In the above-described embodiment, the structure-side locking portion 158 has both the removal restriction function of the cover member 154 and the removal restriction function of the receiving member 153. However, the latter function may be omitted. . Specifically, it is possible to omit the catch between the component side locking portion 158 and the locking recess 167 of the receiving member 153.

  (10) In the above-described embodiment, the both locking portions 158 and 196 are hooked in the recessed space 161 defined by the receiving member 153. However, the both locking portions are outside the recessed space 161 of the receiving member 153. A configuration in which 158 and 196 are caught is also possible. For example, by adopting a configuration in which both locking portions are caught in the internal space of the substrate box 92, unauthorized access to these locking portions can be made more difficult.

  (11) In the above-described embodiment, the engagement can be released when the sum of the displacement amounts of the engagement surfaces 198a and 200a of the engagement portions 158 and 196 reaches a specified value. It is good also as a structure which can cancel | release latching, when the displacement amount of 198a, 200a becomes the maximum.

  (12) In the above embodiment, when the cover member 154 is mounted, the locking portions 158 and 196 are flexibly deformed in synchronism with each other. However, the timing at which the flexural deformation occurs is not necessarily synchronized. That is, when both locking parts come into contact, one locking part is first bent and deformed, bent to a regulated limit, and after the bending deformation is suppressed, it is pushed by the locking part that is no longer bent. Thus, the other locking portion may be bent and deformed.

  (13) In the above embodiment, the break screw 170 is used as the means for restricting the removal of the cover member 154. However, the break screw 170 may be omitted.

  Moreover, although the cover member 154 is configured to be sandwiched between the two structural members 101 and 102, it may be omitted.

(14) In the above embodiment, the locking mechanism 195 is replaced with the first front side coupling portion 142 and the second front side coupling portion 1.
However, the present invention is not limited to this, and the locking mechanism 195 may be arranged at a position other than between the coupling portions 142 and 143.

  Moreover, although the locking mechanism 195 is disposed on both sides of the central portion of the cover member 154, it can be disposed only on one side. It is also possible to arrange the cover member 154 in the central portion. However, in such a case, there is a concern that the position of the cover member 154 (for example, lifting) is likely to occur. Therefore, it is desirable to dispose the locking mechanism 195 on both sides of at least the center portion.

  (15) In the above embodiment, the cover side latching portion 196 is disposed between the positioning protrusions 177 of the cover member 154. However, it is also possible to dispose the cover side engaging portion 196 at a position other than between the positioning protrusions 177. However, in such a case, it is assumed that the cover member 154 is likely to be displaced when the cover side locking portion 196 is bent and deformed, which is not preferable. Therefore, it is desirable to arrange it between the positioning projections 177.

  (16) In the above embodiment, the second cover plate portion 173 and the outer groove wall portion 157 are in contact with each other on both sides of the structural body side locking portion 158, and the second cover plate portion 173 is on the base side of the structural body side locking portion 158. However, the contact between the second cover plate portion 173 and the planar portion 105 on the base side of the component-side locking portion 158 can be omitted.

  (17) In the above embodiment, the cover member 154 is configured to correspond to the plurality of coupling portions 176. However, it is also possible to provide individual cover members for the individual coupling portions 176.

  In the above embodiment, the cover member 154 is made of synthetic resin, but it can be made of metal instead.

  (18) It is not essential that the receiving member 153 has the recessed space 161, and the locking portion 158 is formed with respect to one plate portion, and when the receiving member 153 alone is viewed, The engaging portion 158 may be exposed instead of being accommodated in the space. In this case, although the locking portion 158 is not accommodated in the space, the security is lowered as compared with the above embodiment, but the configuration of the receiving member 154 can be simplified.

  (19) In the above embodiment, the receiving member 153 is made of metal. However, the receiving member 153 is not limited to metal as long as it has higher strength than the wall portion of the backside structure 102. For example, the receiving member 153 is formed of a material in which a reinforcing agent such as glass fiber is dispersed in a synthetic resin material that forms the back side structure 102 or a synthetic resin material different from the synthetic resin material. Also, the strength may be increased. Further, by forming the receiving member 153 by subjecting a synthetic resin material forming the back side structural body 102 or a synthetic resin material different from that to surface treatment such as plating, the back side structural body 102 You may make it stronger than a wall part.

  (22) In the above embodiment, the re-boxing of both components 101 and 102 (re-collection of the main control board 91) is allowed only once, but the re-boxing may be allowed multiple times. . For example, it is good also as a structure which fixes both the structural bodies 101 and 102 by the one 1st front side coupling | bond part 142, and you may provide in addition the 3rd front side coupling | bond part.

  (23) The configuration applied to the board box 92 of the main control device 63 in the above embodiment 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.

  (24) Other types of pachinko machines different from the above embodiment, such as a pachinko machine in which the electric game object is released a predetermined number of times when a game ball enters the specific area of the special device, or a game ball in the specific area of the special device The present invention can also be applied to a pachinko machine that generates a big hit when entering, a pachinko machine equipped with other objects, 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.

  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 to start the rotation of the reel.

  The technical ideas that can be extracted within the disclosure scope of the second embodiment described in detail above are shown below.

(1). A substrate box (substrate box 92) formed by combining a plurality of box structures (for example, the front-side structure 101 and the back-side structure 102);
A control board (main control board 91) housed in the internal space of the board box;
Fixing means (for example, the couplers 181 and 183 and the receiving member 153) for fixing the plurality of box components to each other in a state in which the inner space of the substrate box is not opened or difficult to remove
Fixtures (joints 181 and 183) constituting the fixing means;
And a receiving member (receiving member 153) that is installed with respect to an installation portion (groove portion 155) provided in the box structure and to which the fixing tool is fixed.
A cover that is attached to the box structure with the receiving member sandwiched between the box structure and covers at least a part of the receiving member while allowing the fixing member to be attached to the receiving member. A member (cover member 154);
Defining portions (positioning protrusions 177, recessed spaces 161, etc.) for defining the relative movement direction of the cover member and the box structure in a predetermined direction when the cover member and the box structure are combined;
Restriction means (locking mechanism 195) for restricting removal of the cover member from the box structure,
The regulating means is
A box-side latching portion (a component-side latching portion 158) provided in the box component,
A cover-side locking portion (cover-side locking portion 196) that is provided on the cover member and that is locked to the box-side locking portion to restrict removal of the cover member from the box structure;
A box-side deforming portion (an arm portion 197 of the component-side locking portion 158) that displaces the box-side locking portion to a side where the locking state with the cover-side locking portion is released by elastic deformation;
A cover-side deformation portion (an upright portion 199 of the cover-side locking portion 196) that displaces the cover-side locking portion to a side where the locking state with the box-side locking portion is released by elastic deformation;
Based on the relative movement of the cover member and the box structure to the side in which the cover member and the box structure are combined among the predetermined directions defined by the defining part, the box side locking portion and the cover side A guide portion (guide portions 158a and 199a) for shifting the locking portion to the locked state;
Based on the elastic deformation of the box side deformable part and the cover side deformable part, both the box side latching part and the cover side latching part are displaced to the side where the latched state is released, so that A gaming machine, wherein the locked state of the box side locking portion and the cover side locking portion is released.

  According to (1), the receiving member is installed with respect to the installation part provided in the box structure, and its removal is regulated by the cover member. Although a structure in which the receiving member is formed by insert molding or the like can be considered when forming the box structure, in this case, it may be difficult to improperly remove the receiving member, but the mold may be complicated. It is not preferable. Moreover, if it is set as the structure which inserts the receiving member provided separately with respect to the box structure after completion, compared with the case where insert molding etc. which are mentioned above are performed, simplification of a metal mold | die can be achieved. On the other hand, there is a concern that unauthorized removal of the receiving member is likely to be performed. If the removal of the receiving member is facilitated in this way, it is assumed that unauthorized opening of the substrate box is likely to be performed, or that the trace of unauthorized opening of the substrate box is easily concealed by crafting the receiving member. From the viewpoint of crime prevention, it is not preferable.

  In this respect, as shown in (1), the receiving member is installed on the installation portion of the box structure, and the removal of the receiving member is a cover member, more specifically, the receiving member is sandwiched between the box structure If it is configured to prevent the cover member from being removed by the restricting means, it is possible to suppress unauthorized removal of the receiving member while suppressing complication of the manufacturing process (mold). Thereby, it is possible to contribute to the suppression of fraudulent acts performed on the substrate box while enabling the substrate box to be formed satisfactorily. Moreover, it becomes possible to provide the cover member with a shielding function that suppresses the exposure of the receiving member, making it difficult to make unauthorized access (physical contact) to the receiving member.

  However, in the case of a configuration having a cover member, it is necessary to attach the cover member, and there is a concern that the work for assembling the substrate box may become complicated. In this respect, in (1), when the cover member is mounted, the cover-side locking portion and the box-side locking are moved by relatively moving the box structure and the cover member in a predetermined direction defined by the defining portion. The parts are displaced and become locked. This restricts the removal of the cover member from the box structure. Therefore, complication of the mounting work of the cover member can be suppressed.

  Further, based on the elastic deformation of the box side deformable portion and the cover side deformable portion, both the box side latching portion and the cover side latching portion are displaced to the side where the latched state is released. Since the locked state is released, it is easy to release the lock. Thereby, improvement in crime prevention can be expected.

(2). The box side deformable portion and the cover side deformable portion are formed so as to allow elastic deformation to a predetermined side,
The displacement direction of the box side latching portion toward the side where the latched state is released is opposite to the displacement direction of the cover side latching portion toward the side where the latched state is released. The gaming machine according to (2), wherein the box side deformable portion and the cover side deformable portion are arranged.

  As shown in (1), when a configuration that requires displacement of both locking portions to release the locked state is used, as the engagement of the locking portions increases, It is assumed that the amount of displacement needs to be increased. In order to realize a stable locking state, it is desirable to increase the allowance. However, due to this, the displacement of the locking portion increases, leading to an increase in the size of the regulating means and an increase in the size of the board box. It becomes easy to do and is not preferable.

  In this respect, as shown in (2), if each deforming part is arranged so that the displacement directions at the time of releasing the lock are opposite to each other, even if the structure in which both the locking parts are displaced together is adopted, It is possible to easily secure the allowance while suppressing an increase in the amount of displacement. As a result, it is possible to suppress the occurrence of inconveniences such as insufficient allowance due to assembly variation, etc., contribute to stabilization of the locked state, and suppress increase in size of the regulating means. Can do.

(3). The cover side latching portion is disposed at a predetermined interval, and when the cover side latching portion is displaced to the release side of the latched state, the cover side latching portion comes into contact with the cover side latching portion to prevent the displacement. A stopper (the inner facing plate 164 of the receiving member 153);
A second side which is disposed at a predetermined interval from the box side latching portion, and abuts against the box side latching portion when the box side latching portion is displaced to the release side of the latched state to prevent the displacement. The gaming machine according to (1) or (2), further including a stopper portion (second cover plate portion 173 of the cover member 154).

  According to (3), the displacement of the locking portion is prevented by the first stopper portion and the second stopper portion. The amount of displacement of each locking portion can be defined by each stopper portion, and displacement of the locking portion beyond that assumed can be avoided. As a result, it is difficult to cover the displacement amount of the other locking portion by displacing only one locking portion and increasing the displacement amount. The displacement of the part can be made indispensable.

  That is, to release the locked state, it is necessary to displace the cover side locking portion and the box side locking portion in different directions and to separate the cover member and the box structure. For example, it is necessary to move the cover member and the box structure relative to each other in a state where one of the locking portions is operated with one hand and the other locking portion is operated with the opposite hand. For this reason, it is difficult for one person to remove the cover member.

  As described above in detail, by making the cover member easy to attach and making it difficult to remove, it is possible to suitably achieve both workability at the time of creating the board box and improvement of crime prevention. it can.

  Further, it is possible to avoid deformation exceeding the elastic deformation region (plastic deformation), and it is possible to protect the box side deformable portion and the cover side deformable portion. Thereby, it is possible to suitably maintain the function of the regulating means, that is, the function of regulating the removal of the cover member.

(4). The displacement direction to the release side of the locked state in the box side locking portion and the displacement direction to the release side of the locked state in the cover side locking portion are set in opposite directions,
The cover side latching portion is disposed at a predetermined interval, and when the cover side latching portion is displaced to the release side of the latched state, the cover side latching portion comes into contact with the cover side latching portion to prevent the displacement. A stopper (the inner facing plate 164 of the receiving member 153);
A second side which is disposed at a predetermined interval from the box side latching portion, and abuts against the box side latching portion when the box side latching portion is displaced to the release side of the latched state to prevent the displacement. A stopper portion (second cover plate portion 173 of the cover member 154),
The first stopper portion and the second stopper portion have a wall shape facing each other, and the cover side locking portion and the box side locking portion are arranged in a region sandwiched between the first stopper portion and the second stopper portion. The gaming machine according to (1), characterized in that is arranged.

  According to (4), in addition to the effects shown in (2) and (3), the following special effects are produced. That is, the box side latching portion and the cover side latching portion are disposed in a region sandwiched between the first stopper portion and the second stopper portion that form a wall shape facing each other. Thereby, the access to each locking part can be made difficult by both stopper parts. Further, even when the locking portion is accessed, it is possible to make it difficult to perform an unauthorized operation of the locking portion by both the stopper portions. Therefore, removal of the cover member can be made more difficult.

  As described above in detail, it is possible to contribute to the multi-function of the stopper portion by providing the both stopper portions with a restriction function for restricting access and operation to the locking portion.

  (5). The maximum displacement amount (gap dimension X12) of the cover side locking portion defined by the first stopper portion is based on a hooking margin (hanging margin X10) between the cover side locking portion and the box side locking portion. And the maximum displacement amount (gap dimension X14) of the box-side locking portion defined by the second stopper portion is the difference between the cover-side locking portion and the box-side locking portion. The gaming machine according to (3) or (4), wherein the gaming machine is set to be smaller than a premium.

  According to (5), the maximum displacement amount of the cover side locking portion and the maximum displacement amount of the box side locking portion are set to be smaller than the allowance between the locking portions. Thereby, the configuration described in (4) and the like described above can be suitably realized. Specifically, even if only one of the locking portions is displaced, the locking state of both locking portions is not released, and the removal restriction of the cover member is maintained. That is, it is possible to make the displacement of both locking portions indispensable for releasing the locked state.

  Note that the technical idea shown in (5) (that is, the relationship between the displacement amount and the allowance) can be applied to (3). The “hanging amount with the stop portion” differs depending on which of the locking portions is used as a reference. Specifically, in the cover side latching portion, an engagement margin with the box side latching portion in the displacement direction of the cover side latching portion is shown. In the box side latching portion, the displacement direction of the box side latching portion is shown. Fig. 6 shows the allowance for the cover side latching portion.

  Incidentally, (5) indicates that “the locking state of the both locking portions is maintained even when the cover side locking portion is displaced so that the maximum displacement amount defined by the first stopper portion is reached. In addition, even when the component side latching portion is displaced so as to have the maximum displacement amount defined by the second stopper portion, the latching state of both the latching portions is maintained. The gaming machine according to (3) or (4), wherein both the stopper portions are formed.

  (6). The gaming machine according to (4) or (5), wherein the first stopper portion is provided on the box component side, and the second stopper portion is provided on the cover member side.

  According to (6), the cover side locking portion is sandwiched between the first stopper portion and the box side locking portion provided on the box structure side, and the box side locking portion is provided on the cover member side. It is sandwiched between the second stopper portion and the cover side locking portion. For this reason, even if the cover member and the box structure are displaced in the displacement direction of the locking portion, the locked state between the box-side locking portion and the cover-side locking portion is easily released. Therefore, it is possible to contribute to the stabilization of the locked state.

  Specifically, if the cover member is displaced toward the side where both the locking portions approach, both the locking portions approach each other, so that the hanging allowance does not decrease. On the other hand, when the cover member is displaced to the side where both the engaging portions are separated from each other, the amount of engagement between the both engaging portions is reduced in accordance with the amount of displacement. However, based on this positional deviation, the first stopper portion approaches the box side locking portion, and the gap dimension between the first stopper portion and the box side locking portion (that is, the maximum displacement amount of the box side locking portion allowed). And the cover-side locking portion approaches the second stopper portion, and the gap dimension between the second stopper portion and the cover-side locking portion (that is, the allowable maximum displacement amount of the cover-side locking portion) also decreases. Become. That is, the maximum displacement amount of each locking portion is also reduced with the decrease in the allowance. Therefore, even if the cover member is displaced, it is avoided that the locked state is easily released.

  If the configuration opposite to the configuration shown in (6) (the configuration in which the first stopper portion is provided on the cover member side and the second stopper portion is provided on the box structure side) is employed, the position of the cover member Along with the displacement, the first stopper portion and the cover side latching portion move together, and the engagement between the latching portions becomes small depending on the positional deviation amount. In such a case, the locked state can be easily released. Therefore, the configuration shown in (6) is preferably adopted.

Further, “the first stopper portion is provided on the side of the box structure” means that the first stopper portion is integrally formed with the box structure, and is formed separately from the box structure. The case where the first stopper portion is mounted on the box structure is shown.
“The second stopper portion is provided on the cover member side” means that the second stopper portion is integrally formed with the cover member and that the second stopper is formed separately from the cover member. The case where the part is attached to the cover member is shown.

(7). The box side locking portion constitutes a part of an outer wall portion (outer groove wall portion 157 of the back side structure 102) that forms an outline of the box structure, and the second stopper portion includes at least the In a predetermined region including the box side locking portion in the outer wall portion, the outer wall portion is confronted,
In the outer wall portion, a distance between the peripheral portion of the box side locking portion and the second stopper portion is smaller than a space size between the second stopper portion and the box side locking portion. The gaming machine according to 6).

  According to (7), even if the second stopper portion is pushed from the outside of the substrate box, the second stopper portion maintains the predetermined gap with the box side locking portion. It abuts with the peripheral part of the box side latching | locking part in a part. Thereby, it can suppress that the external force added to the 2nd stopper part is disperse | distributed by an outer wall part, and the influence by the external force reaches with respect to a box side latching | locking part.

  For example, the outer wall portion and the second stopper portion may be formed so that the outer wall portion and the second stopper portion come into contact with each other on at least both sides of the box side locking portion in a state where the cover member is mounted.

  (8). The gaming machine according to any one of (1) to (7), wherein a space surrounding the regulating means is formed by combining the cover member and the box structure.

  According to (8), since the restricting means is disposed in the space formed by the cover member and the box structure, access to the restricting means can be made difficult. Thereby, it can contribute to the further improvement of crime prevention.

(9). The fixing means includes a first fixing means (for example, the first front side coupling portion 142 and the first coupling tool 181) and a second fixing means (for example, the second front side coupling portion 143 and the second) for individually fixing both the box components. A coupler 183),
The cover member is a member provided across the first fixing means and the second fixing means,
The gaming machine according to any one of (1) to (8), wherein the regulating means is disposed at least between the first fixing means and the second fixing means.

  According to (9), the first fixing means and the second fixing means contribute to fixing with the receiving member, but the fixing of at least one of the fixing means is performed, so that the cover member Removal will also be restricted. That is, the fixing means contributes to the fixing of the cover member, and the unauthorized removal of the cover member can be suitably suppressed.

  Further, if a plurality of cover members are provided, a space is required for disposing restriction means corresponding to each cover member as the number of cover members increases. Such an increase in the regulation means is not desirable because it may hinder the coexistence with the fixing means in a limited installation area. In this regard, as shown in (9), if one restricting means (one cover member) is installed for a plurality of fixing means, a space saving can be achieved and a practically preferable configuration can be realized.

(10). The receiving member is formed of a series of opposing plate portions (inner counter plate portion 164 and outer counter plate portion 165) facing each other and a connecting plate portion (connecting plate portion 166) connecting the counter plate portions. A groove portion (recessed space 161) is provided, and a fixing portion (locking piece 168) for fixing the fixture in the groove portion is provided corresponding to at least the first fixing means and the second fixing means. Further, the fixing of the fixing tool to the receiving member is performed in the groove portion,
A locking portion (a part of the component-side locking surface 198a and a cover-side locking surface 200a) between the cover-side locking portion and the box-side locking portion is disposed in the groove. The gaming machine according to (9).

  According to (10), the locking portions of the both locking portions are positioned in the groove portion of the receiving member. For this reason, the receiving member can make it difficult to access the locking portion between the locking portions. That is, it is possible to make it difficult to remove the cover member by the receiving member while suppressing the unauthorized removal of the receiving member by the cover member.

  (11). The cover member has an opening (through hole 174) that allows the fixture to enter the groove, and covers a region other than the opening at the entrance of the groove (first cover plate). The gaming machine according to (10), wherein a portion 172) is formed.

  According to (11), the entrance of the groove portion is covered by the cover portion of the cover member. The cover member itself (specifically, the cover portion) can suppress exposure of the locking portion disposed in the groove portion. Thereby, a practically preferable configuration can be realized.

  In addition, it is possible to insert a fixing tool through the opening, and the function of fixing the box components to each other is secured by the fixing tool and the receiving member.

  (12). The cover member is formed so as to enter the internal space of the substrate box, and a sandwiched portion (receiving plate portion 185) that is sandwiched between the plurality of box constituent bodies fixed to each other is formed. The gaming machine according to any one of (1) to (11), which is characterized.

  According to (12), the cover member has the to-be-clamped part clamped by the several box structure. For this reason, after the two components are combined, the cover member can be held in a more stable state. By sandwiching the cover member in this way, it is possible to suppress a local load from being applied to the regulating means even when the cover member is pulled.

  (13). The relative movement direction of the cover member and the box structure defined by the defining portion is a displacement direction to the side of releasing the locking state in the cover side locking portion, and in the box side locking portion. The gaming machine according to any one of (1) to (12), wherein the gaming machine is set so as to intersect with both directions of the direction of displacement toward the side of releasing the locked state.

  In the configuration shown in (1) to (12), when the relative movement direction when separating the cover member and the box structure is the same as the displacement direction of one of the locking portions toward the locking release side In one operation, the displacement of one of the locking portions and the movement of the cover member in the detaching direction can be performed simultaneously. More specifically, it is assumed that the operation of removing the cover member can be performed while operating one locking portion with one hand and operating the other locking portion with the other hand. Such integration of operations is not preferable from the viewpoint of regulating the removal of the cover member.

  In this regard, according to (13), since the relative movement between the cover member and the box structure and the displacement of the locking portion can be set to be in independent directions, the above operations can be integrated. The removal of the cover member can be suitably controlled.

(14). In the predetermined range of the entire range in which the combination direction of the cover member and the box structural body is defined by the defining portion, the guide member extends in the predetermined direction defined by the defining portion. And a guide part that deforms the box side deformation part and the cover side deformation part to the side that intersects the predetermined direction and is away from each other based on relative movement between the box structure and the box structure,
When the box structure and the cover member are further moved relative to the combination of the box structure and the cover member beyond the predetermined range, the cover side locking portion and the box side locking portion Is shifted from the guide state by the guide portion to the locked state as the box-side deformable portion and the cover-side deformable portion are deformed to return to the state before deformation based on their own elastic force. The gaming machine according to any one of (1) to (13), wherein:

  According to (14), the cover member and the box structure are combined to shift to a state in which the removal of the cover member is restricted. Specifically, based on the relative movement of the cover member and the box structure, the two deforming portions are elastically deformed to the side that intersects a predetermined direction and is separated from each other by the guide portion. When the relative movement is further performed, the guide by the guide unit is finished, and both deformed units are deformed to return to the state before the deformation by their own elastic force. Thereby, a cover side latching | locking part and a box side latching | locking part will be in a latching state, and isolation | separation with a cover member and a box structure is controlled.

  As described in detail above, when the cover member and the box structure are combined, it is possible to shift to the locked state by the relative movement of both, and no separate operation is required for shifting to the locked state. Thereby, it is possible to make it difficult to remove the cover member while facilitating the attaching operation of the cover member.

  The basic configurations of various gaming machines to which the above (1) to (14) can be applied are shown below.

  Pachinko gaming machine: operation means operated by a player, game ball launching means for launching a game ball based on the operation of the operation means, a ball path for guiding the launched game ball to a predetermined game area, and a game A gaming machine that includes each gaming component arranged in an area, and gives a bonus to a player when a gaming ball passes through a predetermined passing portion of each gaming component.

The first deformation part and the second deformation part are arranged,
Based on the elastic deformation of the first deformation part and the second deformation part, both the first locking part and the second locking part are displaced to the side where the locked state is released, so that It has become the composition where the locked state of the 1st locking part and the 2nd locking part is canceled ,
The first locking portion is arranged at a predetermined interval from the first locking portion, and when the first locking portion is displaced to the unlocked side of the locking state, the first locking portion is brought into contact with the first locking portion to prevent the displacement. A stopper,
The second locking portion is disposed at a predetermined interval from the second locking portion, and when the second locking portion is displaced to the locking state release side, the second locking portion abuts on the second locking portion and prevents the displacement. Stopper and
With
The maximum amount of displacement of the first locking part defined by the first stopper part is set smaller than the engagement margin between the first locking part and the second locking part, and the second stopper part A gaming machine characterized in that a prescribed maximum displacement amount of the second locking portion is set to be smaller than an allowance between the first locking portion and the second locking portion .
