Description

  The present invention relates to a gaming machine.

  As multiple types of gaming machines, pachinko gaming machines and slot machines are known. These gaming machines include a control board on which electronic components such as a ROM storing a CPU and a control program related to a game are mounted, and a series of games are controlled by the control board. In recent years, there are CPUs and ROMs that are made into one chip and mounted on a control board.

  In this type of gaming machine, for the purpose of obtaining illegal profits, control such as changing the contents of the game by exchanging the ROM in the control board (if the CPU or ROM is a single chip, the chip) Many fraudulent acts against substrates have been reported, and various fraud countermeasures have been studied.

  For example, a plurality of box components constituting the board box are fixed to each other, and a fixing structure (so-called caulking structure) for making it impossible or difficult to release the fixing state at the fixing portion is provided. Is known (see, for example, Patent Document 1). The fixing structure is configured to require destruction when releasing the fixing. Thereby, when the substrate box is opened, an opening history due to the destruction can be left, and when the substrate box is illegally opened, it can be found.

  The fixing structure described above includes a fixing tool and a receiving member that receives the fixing tool, and the box components are fixed to each other by hooking the fixing tool and the receiving member. The receiving member is provided separately from the box structure and is installed on the completed box structure. Thus, by making the receiving member separate, it is suppressed that the structure of the metal mold | die which shape | molds a box structure is complicated too much.

  First, the invention that can be extracted from the present embodiment will be described while showing effects and the like as necessary.

Means 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 the means 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 this means, the receiving member is installed on the installation portion of the box structure, and the removal of the receiving member is performed with the receiving member sandwiched between the cover member and the box structure. If the cover member is provided so as to be prevented 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 this means, when the cover member is mounted, the cover-side locking portion and the box-side locking portion are moved by relatively moving the box structure and the cover member in a predetermined direction defined by the defining portion. 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.

Mean 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 means 1, characterized in that the box side deformation portion and the cover side deformation portion 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 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 means 1 or 2, further comprising a stopper portion (second cover plate portion 173 of the cover member 154).

  According to the means 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.

Means 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 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 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.

  Means 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 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 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 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 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.

  It is possible to apply the technical idea shown in this means (that is, the relationship between the amount of displacement and the allowance) to the means 3, but in such a case, “the cover side locking part and the box side locking part The “hanging allowance” differs depending on which locking portion 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, this means is described as follows: "Even if the cover side 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 component side locking portion is displaced so as to be 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. 6. The gaming machine according to means 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 the means 6, the cover side latching portion is sandwiched between the first stopper portion provided on the box component side and the box side latching portion, and the box side latching portion is provided on the cover member side. 2 It is pinched | interposed by the stopper part and the cover side latching | locking part. 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 a configuration opposite to the configuration shown in this means (a configuration in which the first stopper portion is provided on the cover member side and the second stopper portion is provided on the box component side) is adopted, the position of the cover member is shifted. Along with this, the first stopper portion and the cover-side locking portion move together, and the engagement between the locking portions becomes smaller depending on the amount of positional deviation. In such a case, the locked state can be easily released. Therefore, the configuration shown in this means 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.

Mean 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,
Means characterized in that a distance between the peripheral part of the box side locking part and the second stopper part in the outer wall part is smaller than a distance between the second stopper part and the box side locking part. 6. The gaming machine according to 6.

  According to the means 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. In contact with the peripheral portion of the box side locking portion. 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.

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

  According to the means 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.

Means 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 means 1 to 8, wherein the restricting means is disposed at least between the first fixing means and the second fixing means.

  According to the means 9, the first fixing means and the second fixing means contribute to fixing to the receiving member, but the cover member is removed by fixing using at least one of the fixing means. Will also be regulated. 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 this means, if one restricting means (one cover member) is installed for a plurality of fixing means, a space-saving configuration can be achieved and a practically preferable configuration can be realized.

Means 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. A gaming machine according to claim 9.

  According to the means 10, the locking portions of the both locking portions are located 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.

  Means 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 claim 10, wherein a portion 172) is formed.

  According to the means 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.

  Means 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. A gaming machine according to any one of means 1 to means 11 characterized.

  According to the means 12, the cover member has a sandwiched portion that is sandwiched by a plurality of box structures. 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.

  Means 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 the means 1 to 12, characterized in that the game machine is set so as to intersect with both directions of the displacement direction toward the side to release the locked state.

  In the configuration shown in the means 1 to means 12, when the relative movement direction when separating the cover member and the box structure is the same as the displacement direction of any of the locking portions toward the unlocking side, By this 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 respect, according to the present means, 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, it is possible to integrate the operations as described above. It becomes difficult and the removal of the cover member can be suitably regulated.

Means 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. A gaming machine according to any one of means 1 to means 13, characterized in that:

  According to the means 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, 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. 10 (a) and 10 (b), the hook portion 111 is inserted into the locking receiver 121, As shown in FIG. 10A, 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. 10B, the hook portion 111 is sandwiched between both the lower peripheral wall portion 123 and the inner wall portion 126 constituting 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. 10B, in the restricted state where 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 is accordingly 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. 10B, a predetermined gap is formed between the base portion 110 that continues to the lower frame portion 114 and the lower pedestal portion 125, 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 in the outer side rather than the base part 110 of the front side peripheral edge part 103, as shown in FIG.10 (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 using FIG. 11 in comparison with a configuration in which the size of the board box 92 is increased. FIG. 11A is a cross-sectional view showing a restriction location of the substrate box 92 in the pachinko machine 10, and FIG. 11B 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. 11B, the hook portion 132 and the locking receiver 133 are in a reverse relationship with 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. On the other hand, 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 a multi-function of the pachinko machine 10.

  Next, the assembling work of the front side structural body 101 and the back side structural body 102 by the restriction means will be described with reference to FIG. FIGS. 12A to 12C are explanatory views for explaining the assembly work of the front side structural body 101 and the back side structural body 102.

  When the front-side structure 101 and the back-side structure 102 are fixed to each other, first, the hook portion 111 is engaged from the back side of the back-side structure 102 so that the state shown in FIG. 12A is changed to the state shown in FIG. 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 are completely overlapped, 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. 8 and 9, 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 106 of the back side structure 102 (see FIG. 13 and the like). 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 receiving member 153 is formed by bending a metal plate having a strength (hard) higher than that of at least the wall portion of the backside 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. 9 and 14, among the opposing plate portions 164 and 165 of the receiving base portion 162, an engaging recess 167 is provided in the outer opposing plate portion 165 (hereinafter referred to as the outer opposing plate portion 165). 9 is formed at a plurality of locations, and as shown in FIG. 9, 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. 8, 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. 14, 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. 13, the cover member 154 includes a first cover plate portion 172 and a second cover plate portion 173 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. 15A, 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. 13, one through-hole portion 174 and one position aligned with the substrate box 92 in the thickness direction. 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. 15 (a) and 15 (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. 15B, positioning projections 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. 16A in addition to FIG. 9, FIG. 14, and FIG. FIG. 16A is a partial sectional view taken along line BB in FIG.

  As shown in FIG. 9 and the like, a cylindrical portion 178 is integrally formed at the center of the first cover plate portion 172 so as to stand up from the first cover plate portion 172 toward the front side component 101. 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.

  9 and 14, 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. 16, 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. 16, a shielding portion 180 that closes an 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. 16 (b), a state in which the two structural bodies 101 and 102 are combined, more specifically, as shown in FIG. 12 (b), although the two structural bodies 101 and 102 are combined, 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, the flow of work for forming the back side coupling region 151 and the flow of work for combining both the structural members 101 and 102 will be described with reference to FIGS. FIGS. 17A to 17D are explanatory diagrams for explaining the work in forming the back side coupling region 151. Note that FIGS. 17A and 17B and FIGS. 17C and 17D show cross sections at positions shifted in the longitudinal direction of the cover member 154 for convenience of explanation.

  As shown in FIG. 17B, 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 as to be in the state.

  As shown in FIG. 17B, 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 recess 167 of the receiving base portion 162 is engaged. 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.7 and FIG.9). 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. 17C, 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. 17D). 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. 16A, 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. 8 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. 18A, and then the second front side coupling portion 143 will be described based on differences from the first front side coupling portion 142. FIG. 18A 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. 18A, a metal first coupler (fixing tool) 181 is inserted into the through-hole sections 144 and 174 communicated with each other from the first front-side coupling section 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 accommodating recess 182 is set to be substantially the same as the outer periphery of the operation portion 181b (see FIG. 8), and after the operation portion 181b is accommodated in the accommodating 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.18 (b). FIG. 18B 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.

  Further, as shown in FIG. 8 and the like, a notch portion 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. FIG. 19 is a partial cross-sectional view taken along the line CC of FIG.

  As shown in FIG. 19, a locking claw portion 143d is formed in the housing recess 184 (specifically, the peripheral wall portion 143b) as a temporary locking portion that protrudes inward and is hooked on the locking hole 183c. On the peripheral wall portion 143b, a component-side movable portion 143e is formed that enables bending deformation (elastic deformation) of the portion including the locking claw portion 143d based on the insertion of the second coupler 183 (see FIG. 9). ). 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. 19, in a state where the locking claw portion 143d is hooked to the locking hole portion 183c, that is, in a temporarily fixed state, the tip end portion 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.

  Further, as shown in FIG. 7, 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. 18, 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. 15 (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 a coupled state will be described with reference to FIG. FIGS. 20A to 20C 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. 20A, 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 to form the back side coupling area 151. Accordingly, as shown in FIG. 20B, 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. 20 (c), the first coupler 181 is inserted into the through-hole portions 144 and 174 communicated with each other by inserting the first coupler 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. 19 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. 21, 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 will be described. explain. FIGS. 21A to 21C are explanatory diagrams for explaining a work flow when the fixed state of the front side structure 101 and the back side structure 102 is released.

  When releasing the fixed state of the front-side structure 101 and the back-side structure 102, as shown in FIG. 21A, the connection between the first front-side coupling portion 142 and the bulging portion 104 that are in a coupled state 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. 21 (b), by sliding and moving at least one of the front side structural body 101 or the back side structural body 102 in the direction regulated by the regulating means comprising 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. After that, as shown in FIG. 21C, 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. 18B, 19, 21D, and 21E. FIG. 21D and FIG. 21E 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. 21 (d) → FIG. 21 (e), the second coupler 183 is shifted to the state of FIG. 19 → FIG. 18 (b).

  As shown in FIG. 21 (c), after separating both components 101 and 102 and inspecting the main control board 91 and CPU chip 93, the components 101 and 102 are combined again (FIGS. 19 and 21 (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. 19 and FIG. 21 (d), the second coupler 183 temporarily fixed by the locking claw 143d is pushed into the back side structure 102 side, and FIG. 18 (b) and FIG. The state is shifted to the state e) (see FIG. 19 for the locking claw 143d). As shown in FIG. 18B, the second coupler 183 pushed in is hooked with the locking piece 168, and the second front side coupling portion 143 and the back side coupling portion 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. 8, a pasting plate portion 191 is provided on the short side portion of the substrate box 92 opposite to the side on which 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, hereinafter, the locking mechanism and the configuration related thereto will be described in detail based on FIG. 8, FIG. 9, FIG. 15, and FIG. 22 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. 22, 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. 8 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. 8) will be described below, and the other locking mechanism (the lower side in FIG. 8). The description of the locking mechanism 195) will be omitted.

  As shown in FIGS. 9 and 22, 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. 22). 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 and has an upright portion 199 that stands up from the first cover plate portion 172. 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. 9 and 22, 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 engagement allowance of both the locking portions 158 and 196 (specifically, the locking surfaces 198a and 200a) and the amount of deformation of the both locking portions 158 and 196 will be described in detail with reference to FIGS. . FIG. 23A is a schematic view showing a state in which the deformation deformation of the structural body side locking portion 158 is restricted, and FIG. 23B is a schematic view showing a state in which the deformation deformation of the cover side locking portion 196 is restricted. FIG. 23 (c) is a schematic view 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 dashed-two dotted line shown in FIG. 22 shows the state in which each latching | locking part 158,196 is bent and deform | transforming simplified.

  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. 22, 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 to the 2nd cover board part 173, the catch of both the latching | locking parts 158 and 196 is maintained (refer Fig.23 (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. 22, 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.23 (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. 23C).

  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 such that the displacement amount of the component-side locking surface 198a reaches a specified value (specified displacement amount) X11 as shown in FIGS. 23 (a) and 23 (c). Thus, even if the structure side latching | locking part 158 bends, it becomes the structure maintained. Specifically, as shown in FIG. 22, the engagement margin 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. 22, the structural body side locking portion 158 has a structural body side guide portion 158 a that bends both the locking portions 158 and 196 toward the side 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. 24 (a) to 24 (d) are schematic diagrams showing the flow of work when the cover member 154 is mounted. When mounting the cover member 154, FIG. 24 (a) → FIG. 24 (b) → FIG. ) → Work is performed in the order of FIG.

  As shown in FIG. 24A, as a preparation stage for mounting the cover member 154, first, the receiving member 153 is 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. 24B, the cover member 154 is pushed in so that the positioning protrusion 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. 24B, 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. 24C).

  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. 22, a power supply line is indicated by a double line arrow, and a signal line is indicated by a solid line arrow.

  The main control board 91 provided in the main controller 63 incorporates a main control circuit 202 and a power failure monitoring circuit 203. A CPU chip 93 is mounted on the main control circuit 202. The CPU chip 93 temporarily stores various control programs executed by the CPU chip 93 and ROM 205 storing fixed value data, and various data when the control program stored in the ROM 205 is executed.

  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 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 embodiment, the structure-side locking portion 158 has the locking claw portion 198 and the cover-side locking portion 196 has the locking hole portion 200. It is also possible to change. 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 above embodiment, the structure-side latching portion 158 and the cover-side latching portion 196 are bent and deformed in the opposite directions so that the latched state of both the latching portions 158 and 196 is released. 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. FIG. 26 (a) is a schematic view showing the component side locking portion and the cover side locking portion, and FIGS. 26 (b) to 26 (d) show both locking portions as viewed from the direction of attaching and detaching the cover member. FIG. 26 (e) is an explanatory view showing a hook release state of both locking portions 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. 26A, the cover-side locking portion 231 of the cover member 230 is located on the side of the component-side locking portion 158 in the recessed space 161 of the receiving member 153 (specifically, the upper peripheral wall of the back-side structure 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 FIGS. 26 (b) to 26 (d), a description will be given of the allowance for both the locking surfaces 198a and 235a. As shown in FIG. 26 (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. 26 (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 engaging margin of 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. 26C 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. 26 (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. 26C 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. 26 (c), or when the structural body side locking surface 198a is displaced from the state of FIG. 26 (d), as shown in FIG. 26 (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 embodiment. 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, each of the locking portions 158 and 196 is flexibly deformed (elastically deformed) to switch between the locked state and the unlocked state. It may be changed. 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 embodiment, the inner opposing plate portion 164 serving as the “first stopper portion” for restricting the deformation of the cover side locking portion 196 is provided on the back side structural body 102 side. The second cover plate portion 173 serving as the “second stopper portion” for restricting the bending 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. The “two stopper portions” may be provided on the back side structure 102 side.

  For example, as shown in FIG. 27B, 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 above-described embodiment, a part of the outer groove wall part 157 in the back-side structure 102 is formed by the structure-side locking part 158, but the present invention 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 embodiment, the front ends 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”. The bending of the locking portions 158 and 196 is restricted by this, but this is changed so that the portions other than the tip portions of the locking portions 158 and 196 contact the inner facing plate portion 164 and the second cover plate portion 173. The bending may be regulated with

  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. The guide portion may be provided on at least one side. 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 embodiment, the structure-side latching 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 can be omitted. is there. 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 embodiment, both the locking portions 158 and 196 are hooked in the recessed space 161 defined by the receiving member 153. However, both locking is performed outside the recessed space 161 of the receiving member 153. A configuration in which the portions 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 both the surfaces 198a and 200a becomes the maximum.

  (12) In the above-described embodiment, when the cover member 154 is mounted, the locking portions 158 and 196 are configured to bend and deform in synchronization. However, the timing at which the bending 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-described embodiment, the break screw 170 is used as the cover member 154 removal restricting means. 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 disposed between the first front side coupling portion 142 and the second front side coupling portion 143. You may arrange | position in parts other than between each coupling | bond part 142,143.

  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-described embodiment, the cover side locking portion 196 is disposed between the positioning protrusions 177 of the cover member 154. However, it is also possible to dispose the cover side locking 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 component side locking portion 158, and the second cover plate portion is on the base side of the component side locking portion 158. However, the contact between the second cover plate portion 173 and the flat surface portion 105 on the base side of the structural body side locking portion 158 may be omitted.

  (17) Although the cover member 154 is configured to correspond to the plurality of coupling portions 176 in the above-described embodiment, individual cover members may be provided 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 lower than that of 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.

  (20) In the above-described embodiment, the number of box structures forming the substrate box 92 is arbitrary as long as it is plural. Also good. In this case, another box structure may be provided between the main control board 91 and the front side structure 101 so as to block the space between the two, and between the main control board 91 and the back side structure 102. Another box structure may be provided so as to block both spaces.

  (21) In the above-described embodiment, the hook portion 111 and the locking receiver 121 may be omitted, and the front side structure 101 and the back side structure 102 may be bonded to each other with an adhesive at the long side portion of the substrate box 92.

  (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. Good. 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 is 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. Also good.

  (24) Other types of pachinko machines different from the above embodiment, for example, a pachinko machine in which an electric accessory is released a predetermined number of times when a game ball enters a specific area of a special device, or a game ball in a specific area of a special device The present invention can also be applied to a pachinko machine that generates a right if a player enters, 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 take-in 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.
