Is pressed against the left outer wall portion 69 of the base member 62 and the left peripheral wall portion 81 of the cover member 64 so that the right opening is closed by the wall portions 69 and 81, and the base attaching portion 142 and the cover attaching portion 144 are stored inside. In this state, the base member 62 and the cover member 64 are attached (see FIGS. 7 and 8). Further, the seal cover 146 is attached to the base member 62 and the cover member 64 in an inseparable manner by fitting the cover attaching portions 168 and 169 to the corresponding attachment receiving portions 172 and 173. That is, when the seal cover 146 is attached to the base member 62 and the cover member 64, the seal cover 146 is configured so that it cannot be removed unless the second cover attaching portion 169 is destroyed.

(Linkage Department)
As shown in FIG. 8, when the seal cover 146 is attached to the base member 62 and the cover member 64, the seal cover 146 engages with the linkage receiving portion 163 of the seal cutter 148 in the retracted state, A linkage part 170 is provided for displacing the seal cutter 148 from the retracted state to the moved state when the seal cover 146 is removed. The link part 170 is provided on the inner surface of the upper wall of the main body part surrounding the sticking parts 142 and 144 in the seal cover 146, and is formed so as to protrude downward from the upper wall (see FIG. 17). Moreover, the link part 170 is formed in the substantially triangular shape from which the protrusion dimension from an upper wall becomes large as it goes to the left from the right.

(Mounting receiver)
As shown in FIG. 14, the first attachment receiving portion 172 is located below the base attaching portion 142, and is formed in a lower notch portion of the left outer wall portion 69, which is formed in a concave notch opened rearward. 172a, and a cover cutout portion 172b formed in a concave cutout opened forward at the front end portion of the left peripheral wall portion 81 of the cover member 64 that closes the open end of the base cutout portion 172a. An opening that communicates with the slide groove 72 is formed. The second mounting receiving portion 173 includes a base concave portion 173a formed in a step shape opened downward and rearward at the rear left and right central portion of the lower base wall 107 of the base caulking component 90, and the base concave portion 173a. And a front end surface of the lower cover wall 127 of the cover caulking component 94 that closes the rear open end of the cover, and is formed in a concave shape opened downward. As described above, the first attachment receiving portion 172 and the second attachment receiving portion 173 are formed when the base member 62 (base caulking component 90) and the cover member 64 (cover caulking component 94) are combined. The components provided on the side (base notch portion 172a, base recessed portion 173a) and the components provided on the cover member 64 side (cover notch portion 172b, front end surface of the lower cover wall 127) are combined. It has become so. That is, the components provided on the base member 62 side (base notch portion 172a, base recess 173a) or the components provided on the cover member 64 side (front end surface of the cover notch portion 172b, front end surface of the lower cover wall 127) ) The single body cannot hold the first cover mounting portion 168 and the second cover mounting portion 169 that match the components, and the cover mounting portions 168 and 169 can be separated. That is, even if the first cover mounting portion 168 is inserted into the base cutout portion 172a of the base member 62 that forms a part of the first mounting receiving portion 172, if the cover member 64 is not mounted, the base cutout portion 172a is moved backward. Since it is open, the first cover mounting portion 168 can be pulled out rearward from the base cutout portion 172a. Even if the first cover mounting portion 168 is inserted into the cover cutout portion 172b of the cover member 64 that forms part of the first mounting receiving portion 172, the cover cutout portion 172b opens forward unless the base member 72 is mounted. Therefore, the first cover mounting portion 168 can be pulled out from the cover cutout portion 172b to the front side. Similarly, even if the second cover mounting portion 169 is inserted into the base concave portion 173a of the lower base wall 107 that forms part of the second mounting receiving portion 173, if the cover member 64 is not attached, the base concave portion 173a Since it is opened rearward, the second cover mounting portion 169 can be pulled out from the base concave portion 173a to the rear side.

(Linking configuration of seal cover and seal cutter)
As described above, the lower end portion of the seal cutter 148 is rotatably supported by the base sticking portion 142, and the linkage receiving portion 163 provided at the upper end portion is caught by the linkage portion 170 of the seal cover 146. (See FIG. 8). When the seal cover 146 is attached so that the cover attaching portions 168 and 169 are fitted to the corresponding attachment receiving portions 172 and 173 so as to cover both the attaching portions 142 and 144, the linkage portion 170 is attached to both the attaching portions 142 and 142. It is inserted between both sticking parts 142 and 144 from the upper cutter opening 158 between 144 and arranged on the right side of the linkage receiving part 163 in the seal cutter 148 (see FIGS. 8 and 15). That is, when the seal cover 146 is removed from both the sticking portions 142 and 144, the linkage receiving portion 163 is arranged on the right side that is the front side in the displacement direction of the linkage portion 170 that is displaced to the left along with the seal cover 146. The linkage receiving portion 163 of the seal cutter 148 is located on the displacement locus of the portion 170. Then, when the second cover mounting portion 169 is broken and the seal cover 146 is rotated and removed with the first cover mounting portion 168 engaged with the first mounting receiving portion 172 as a fulcrum, the link receiving portion 169 receives the link. The part 163 is pulled so that the seal cutter 148 is rotationally displaced from the retracted state toward the moving state.

  As shown in FIG. 15, in the seal cover 146, the rotational displacement locus of the linkage part 170 from the attached state of the seal cover 146 to the removed state changes from the retracted state of the linkage receiving part 163 in the seal cutter 148 to the moved state. It is set so as to be gradually separated from the directed rotational displacement locus. Accordingly, the seal cutter 148 rotates from the retracted state to the moved state due to the engagement of the linkage portion 170 and the linkage receiving portion 163 with the rotational displacement from the attached state of the seal cover 146 to the removed state within a predetermined range. In addition to the dynamic displacement, the linkage portion 170 and the linkage receiving portion 163 are disengaged when the predetermined range is exceeded, and the seal cover 146 and the seal cutter 148 are separated. The linkage portion 170 of the seal cover 146 in the attached state to the both sticking portions 142 and 144 and the linkage receiving portion 163 of the seal cutter 148 in the retracted state are arranged so that the vertical positions are approximately aligned. In the substrate case 32, the rotation fulcrum (first cover attachment portion 168) of the seal cover 146 from the attached state to the removed state is the rotation fulcrum (cutter shaft) of the seal cutter 148 set at the lower end of the seal cutter 148. The distance from the pivot fulcrum of the seal cover 146 to the linkage part 170 is longer than the distance from the pivot fulcrum of the seal cutter 148 to the linkage receiving part 163. Has been. As a result, the rotational displacement locus taken by the linkage part 170 when the seal cover 146 is turned from the attached state to the removed state is taken by the linkage receiving part 163 when the seal cutter 148 is turned from the retracted state to the moved state. It is set so as to gradually shift to the outer side (left side away from the main body portion of the substrate case 32) from the rotational displacement locus. That is, the linkage portion 170 of the seal cover 146 and the linkage receiving portion 163 of the seal cutter 148 are both rotated within the range of the contact surfaces extending in the radial direction of the arcuate rotation displacement locus. Even if the displacement trajectory is deviated, the mutual engagement is maintained, and both the rotational displacement trajectories are deviated beyond the abutting surfaces, whereby the linking portion 170 is detached from the linking receiving portion 163.

  Here, the linkage part 170 and the linkage receiving part 163 are configured to maintain the engagement until the second cutting part 165 of the seal cutter 148 comes out (to the left) from both the sticking parts 142 and 144. Therefore, most of the seal seal S can be cut by the first cutting portion 164 and the seal seal S attached to the cover sticking portion 144 can be cut in the left-right direction. In addition, the linkage part 170 and the linkage receiving part 163 are preferably configured so as to be disengaged before or at the same time as reaching the rotation limit of the seal cutter 148 from the retracted state to the moving state. By comprising, damage to the seal cutter 148 can be prevented.

(Board case mounting structure)
A structure for attaching the substrate case 32 to the installation member 22 will be briefly described. The substrate case 32 is provided at the center of the front edge of the left outer wall portion 69 of the base member 62 so as to be positioned on the front side of the base adhering portion 142, and a receiving portion (not shown) provided on the front surface of the installation member 22. A hooking portion 176 (see FIG. 7) to be hooked and a positioning hole provided in the upper portion of the right peripheral wall portion 82 of the cover member 64 and through which a positioning pin (not shown) provided on the front surface of the installation member 22 is inserted. A positioning portion 177 (see FIG. 3) and a case fixing portion 178 (see FIG. 3) provided on the upper portion of the right peripheral wall portion 82 are provided. Note that an attachment 179 is attached to the case fixing portion 178. The substrate case 32 is attached to the case fixing portion 178 while the hook portion 176 is hooked on the receiving portion of the installation member 22 and the positioning pin of the installation member 22 is inserted into the positioning hole of the positioning portion 177. The attachment member 179 is detachably assembled to the installation member 22 by engaging with a holding hole (not shown) provided in the installation member 22.

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

(Assembly of caulking means)
The fixing member 98 is inserted from the front opening of the base insertion portion 93 in the base connecting portion 92, and the left and right second fixing piece portions 98 b and 98 b in the fixing member 98 are passed through the left and right member insertion openings 115 and 115. The first fixing piece 98a of the fixing member 98 is pushed in by the fixing piece 114 until the backward movement is restricted. At this time, the lock fixing portion 99 of the fixing member 98 is inclined so as to extend to the inner side of the opening of the base insertion portion 93 from the front side in the insertion direction of the fixing member 98 to the rear side. 114 is elastically deformed toward the outer side of the opening by contact with 114, and insertion into the member insertion opening 115 is allowed. Then, when the lock fixing portion 99 is positioned on the rear side of the member fixing piece 114 through the member insertion opening 115, the fixing member 98 moves to the inner side of the opening of the base insertion portion 93 as it moves forward from the rear. Return to the original tilted posture. That is, when the fixing member 98 is disposed in the base insertion portion 93, the lock fixing portion 99 is hooked on the member fixing piece 114 to restrict the forward movement, and the first fixing piece portion 98 a is attached to the member fixing piece 114. Since the rearward movement is restricted by being caught, the base insertion portion 93 that opens in the front-rear direction is prevented from coming off. Further, the fixed member 98 is supported by the vertical support piece 117 while the second fixed piece portion 98b is sandwiched between the upper and lower installation pieces 112 and 112 and the base lock holding pieces 116 and 116, and the vertical movement is restricted. Thus, the displacement of the second fixed piece 98b toward the outside of the opening of the base insertion portion 93 is restricted. Thus, when the fixing member 98 is inserted into the base insertion portion 93, it is held at an appropriate position.

  Next, the closing member 102 is inserted from the front opening of the base insertion portion 93 in the base connecting portion 92, and the upper and lower closing claw portions 121, 121 in the closing member 102 are passed through the upper and lower closing insertion holes 113, 113, respectively. The member fixing piece 114 is pushed in until the closing main body 120 of the closing member 102 is restricted from moving backward. At this time, the claw pieces at the extending end of the closing claw portion 121 in the closing member 102 are respectively hooked on the claw hook portions 118 provided on the upper and lower cylinder walls of the base connecting portion 92, and the base connecting portion 92 is closed by the closing main body 120. It is prevented from coming off while the front opening is closed. In this way, the closing member 102 is fitted and killed in the front opening of the base connecting portion 92, so that the fixing member 98 accommodated in the base insertion portion 93 by the closing member 102 is externally connected to the fixing member 98. Access can be prevented, and unauthorized actions such as removing the fixing member 98 can be prevented. The fixing member 98 and the closing member 102 can be assembled even after the base member 62 and the cover member 64 are assembled.

  By assembling the base member 62 and the cover member 64, the caulking protrusion 129 and the caulking opening 109 are fitted to each other, and the upper and left base walls 106 and 108 are overlapped with the cover walls 126 and 128. The base connecting portion 92 and the cover connecting portion 96 are aligned in a state where they overlap in the front-rear direction so that the insertion portions 93 and 97 communicate with each other. The lock member 100 is inserted from the rear opening of the cover insertion portion 97 in the cover connecting portion 96 until the lock engaging portion 125 of the lock member 100 is restricted in movement by the lock restricting portion 133 of the cover connecting portion 96. Move forward. At this time, the lock fixing portion 99 of the fixing member 98 is inclined so as to extend toward the inside of the opening of the base insertion portion from the rear side to the front side with respect to the lock member 100 inserted from the rear to the front. Therefore, the elastic member is elastically deformed toward the outside of the opening by contact with the lock member 100, and the lock member 100 is allowed to be inserted into the base insertion portion 93. When the lock member 100 arrives at the insertion position, the lock fixing portion 99 of the fixing member 98 is positioned at the opening-shaped lock engaging portion 124 of the lock member 100, and the lock fixing portion 99 is opened to the base insertion portion 93. Return to the original tilted posture that extends inward. That is, when the lock member 100 is disposed so as to straddle the base insertion portion 93 from the cover insertion portion 97, the lock engaging portion 125 of the lock member 100 is caught by the lock restricting portion 133 of the cover connecting portion 96 and exceeds the insertion position. Further, the forward movement is restricted, and the lock fixing portion 99 is hooked on the lock engaging portion 124 and the backward movement is restricted, so that the cover insertion portion 97 that opens rearward cannot be removed. Yes.

  Next, the lid member 104 is inserted from the rear opening of the cover insertion portion 97, and the lid claw portion 139 and the lid leg portion 140 of the lid member 104 are respectively passed through the corresponding lid insertion openings 135 to lock the lid body 138. Push in until the rear end surface of the member 100 abuts the forward movement. At this time, the claw pieces 139a at the extending end of the lid claw portion 139 in the lid member 104 are respectively hooked on the lid retaining portions 136 provided on the left and right cylindrical walls of the cover connecting portion 96A, and the cover body 138 inserts the cover. It is prevented from coming off while the rear opening of the portion 97 is closed. Thus, the lid member 104 is fitted into the rear opening of the cover insertion portion 97 and killed, so that the lid member 104 opens the rear opening with respect to the lock member 100 accommodated in the cover insertion portion 97 and the base insertion portion 93. It is possible to prevent access from the outside via the cable and to prevent an illegal act such as removing the lock member 100. In the embodiment, after the lid member 104 is attached to the cover connecting portion 96A, an adhesive is poured into the insertion portions 93 and 97 from a slight gap between the lid member 104 and the cover connecting portion 96A, and the inside is covered by the adhesive. It is stuck.

  The caulking means configured as described above cannot be removed from the connecting portions 92 and 96 without destroying the lock member 100, the fixing member 98, the closing member 102, and the lid member 104. Further, even if the caulking means tries to slide and displace the base member 62 and the cover member 64 relative to each other in the left-right direction, the lock member 100 made of metal and having a rigidity is caught by both the connecting portions 92 and 96, so that the base member The relative slide displacement between 62 and the cover member 64 can be prevented. Further, even if the caulking means applies a force so as to separate the base member 62 and the cover member 64 in the front-rear direction, the lock member 100 is engaged with the base member 62 and the cover connecting portion. The front and rear separation displacement with respect to the cover member 64 can be prevented. Thus, in the state in which the caulking means is configured, the substrate case 32 cannot be opened without destroying the caulking means, and the main control board 31 can be appropriately protected from unauthorized access. Moreover, even if the substrate case 32 is opened, the broken caulking means remains as a trace, so that the presence or absence of the opening can be easily grasped.

  According to the caulking means of the embodiment, only by inserting the lock member 100 into the both insertion portions 93 and 97 from the cover connecting portion 96 side, the lock fixing portion 99 disposed in the base connecting portion 92 is locked to the lock member 100. The lock connecting portion 96 of the cover connecting portion 96 is hooked on the lock engaging portion 125 of the lock member 100 and the base connecting portion 92 and the cover connecting portion 96 are held by the lock member so as not to be separated. As described above, the connecting operation of the connecting portions 92 and 96 by the lock member 100 can be performed very simply by inserting the connecting portions 93 and 97 into the both inserting portions 93 and 97 without using a tool. . Further, the caulking means is configured so that the closing member 102 and the lid member 104 can be attached by claw fitting only by being pushed into the corresponding insertion portions 93 and 97. Can be carried out very easily without the need for a squeezing means, and the time and labor required for assembling the caulking means can be further reduced. That is, the assembly operation of the substrate case 32 can be simplified even if there is a caulking means for preventing the substrate case 32 from being illegally opened by the lock member 100 that holds the connecting portions 92 and 96 inseparably.

  In the caulking means, both insertion portions 93 and 94 in which the lock member 100 is accommodated are closed by a closing member 102 fitted to the base connecting portion 92 and a lid member 104 fitted to the cover connecting portion 96A. Therefore, the blocking member 102 and the lid member 104 can prevent the lock member 100 from being accessed from the outside, and prevent unauthorized opening of the substrate case 32 more reliably. In addition, the fixing means 98, the lock member 100, the closing member 102, and the lid member 104 are connected to the connecting portions 92, 96 by using a hook between members or clamping between members without using a fastener such as a screw. Therefore, a boss or a hole for fastening the fastener is not required, and the whole can be made compact.

(About the seal cover mounting structure)
When the seal cover 146 is attached, the first cover attaching portion 168 is inserted into the first attachment receiving portion 172 and the first cover attaching portion 168 is hooked on the opening edge of the first attachment receiving portion 172. The seal cover 146 is rotated upward with the first cover mounting portion 168 as a fulcrum. The seal cover 146 rotates with the first cover mounting portion 168 hooked on the first mounting receiving portion 172 as a fulcrum, so that the second cover mounting portion 169 is aligned with the second mounting receiving portion 173 without deviation, and the first The seal cover 146 is attached to the base member 62 and the cover member 64 in a state of covering the base attaching part 142 and the cover attaching part 144 by pushing the two cover attaching part 169 into the second attachment receiving part 173. Here, since the right surface of the second cover mounting portion 169 that contacts the lower base wall 107 when it is pushed into the second mounting receiving portion 173 is inclined, the second mounting receiving portion 173 of the second cover mounting portion 169 is inclined. Smooth fitting is allowed. Since the upper and lower surfaces and the left surface of the second cover attachment portion 169 extend in the front-rear direction, the second cover attachment portion 169 is caught by a wall that defines the second attachment receiving portion 173 and is prevented from coming off. As described above, when the seal cover 146 is attached to the base member 62 and the cover member 64, the cover attaching portions 168 and 169 are caught on the walls defining the attachment receiving portions 172 and 173, and the cover attaching portions 168, The seal cover cannot be removed without destroying 169 or the like. That is, it is possible to prevent an illegal act such as removing the seal cover 146 to gain access to the seal seal S or the main control board 31. In addition, since the seal cover 146 cannot be removed without destroying the cover attaching portions 168, 169, etc., it is possible to prevent an illegal act such as reusing the removed seal cover 146.

  When the seal cover 146 is attached, when the first cover attachment portion 168 hooked on the first attachment receiving portion 172 is rotated as a fulcrum, the seal in the retracted state is placed on the rotational displacement locus of the linkage portion 170 of the seal cover 146. The linkage receiving portions 163 of the cutter 148 are in an intersecting relationship. When the seal cover 146 is attached, the right side surface, which is the front side in the advancing direction of the linking portion, is inclined, and elastically deformed so that the connection receiving portion 163 of the seal cutter 148 branches from the cutter body and comes close to the cutter body. Therefore, when the seal cover 146 is attached, the linking part 170 easily climbs over the linking receiving part 163 and is disposed on the right side of the linking receiving part 163. That is, according to this configuration, when the seal cover 146 is attached, the linkage part 170 of the seal cover 146 and the linkage receiving part 163 of the seal cutter 148 can be prevented from being damaged.

  The substrate case 32 is provided with a linkage portion 170 inside the seal cover 146, and the linkage portion 170 of the seal cover 146 in the attached state and the linkage receiving portion 163 of the seal cutter 148 in the retracted state are connected to the base attaching portion 142. And the cover adhering part 144, the access to the engaging part between the linking part 170 and the linking receiving part 163 can be prevented by both the adhering parts 142, 144 and the seal cover 146. it can. That is, before removing the seal cover 146, an operation of releasing the engagement between the connecting portion of the seal cover 146 and the linkage receiving portion 163 of the seal cutter 148 is performed from the outside of the seal cover 146, and the sealing seal S is performed by the seal cutter 148. Unauthorized actions such as removing the seal cover 146 so as not to be cut can be prevented.

(Linking structure of seal cover and seal cutter)
When removing the seal cover 146, the second cover mounting portion 169 is broken with a cutting tool, and the seal cover 146 is moved to the left with the first cover mounting portion 168 hooked on the first mounting receiving portion 172 as a fulcrum. Rotate. When the linkage receiving portion 163 is pushed by the linkage portion 170 that is displaced to the left along with the rotational displacement of the seal cover 146, the seal cutter 148 is rotationally displaced leftward with the lower cutter shaft portion 162 as a rotational fulcrum. Then, the first cutting portion 164 of the seal cutter 148 that is displaced from the retracted state to the moving state protrudes outward from the cutter opening 158, thereby cutting the sealing seal S covering the cutter opening 158 up and down. Moreover, also about the 2nd cutting part 165 of the seal cutter 148, the site | part affixed on the rear surface of the cover sticking part 144 in the seal sticker S is cut | disconnected from right to left. As described above, the engagement between the linkage portion 170 of the seal cover 146 and the linkage receiving portion 163 of the seal cutter 148 causes the seal cutter 148 to be accommodated between the two sticking portions 142 and 144 in conjunction with the removal of the seal cover 146. Since the seal seal S is cut by moving from the retracted state to a moving state protruding from both the sticking portions 142 and 144, an illegal act of reusing the seal seal S can be prevented.

  In this way, the lower end portion of the seal cutter 148 is pivotally connected to the base sticking portion 142 so that the seal cutter 148 has a retracted state and a moving state with respect to the base sticking portion 142 and the cover sticking portion 144. Even if the seal cutter 148 is displaced from the retracted state to the moved state in conjunction with the removal of the seal cover 146, the lower end portion remains connected to the base sticking portion 142. That is, the seal cutter 148 is displaced so as to cut the seal seal S in conjunction with the removal of the seal cover 146, but the lower end portion is connected to the base sticking portion 142 and is not separated from the base sticking portion 142. When the seal cover 146 is removed, it can be avoided that the seal cutter 148 falls or is lost. In addition, since the seal cutter 148 is displaced with the cutter bearing portion 150, which is a connection portion with the base attaching portion 142, as a reference (fulcrum), the seal cutter 148 is hardly affected by fluctuations such as the removal of the seal cover 146. 148 can be stably displaced along a predetermined displacement locus. That is, the seal cutter 148 interferes with the opening edge of the cutter opening 158 and the cutter passage opening 159, and thus it is possible to prevent interlocking troubles such as the disengagement state between the linkage portion 170 and the linkage receiving portion 163. The seal seal S can be more reliably cut during removal. When the seal cutter 148 is reused, the seal cutter 148 is appropriately disposed between the sticking portions 142 and 144 in the retracted state only by returning from the moving state to the retracted state with the lower end of the seal cutter 148 as a fulcrum. Can do. That is, since the seal cutter 148 is configured to be displaced with reference to the cutter bearing portion 150 that is a connection portion with the base sticking portion 142 as a reference (fulcrum), it does not require time and effort for alignment in the retracted state. The configuration for aligning with can also be omitted. Further, it is not necessary to open the substrate case 32 in order to return the seal cutter 148 to the retracted state accommodated between the base sticking part 142 and the cover sticking part 144. Thus, according to the substrate case 32 of the embodiment, the seal cutter 148 can be easily reused.

  The seal cover 146 has a rotational displacement trajectory of the linkage part 170 from the attached state of the seal cover 146 to the removed state, and a rotational displacement of the linkage cutter 148 from the retracted state to the moved state. It is set to gradually move away from the trajectory. That is, in the rotational displacement from the attached state to the detached state in the seal cover 146, the seal cutter 148 is retracted in conjunction with the seal cover 146 over a predetermined range in which the linkage part 170 and the linkage receiving part 163 are engaged. Can be turned and displaced toward the moving state. When the rotational displacement from the attached state to the removed state in the seal cover 146 exceeds the predetermined range in which the linking part 170 and the linking receiving part 163 are engaged, the linking part 170 has a radius larger than that of the linking receiving part 163. By detaching outward in the direction, the linkage portion 170 and the linkage receiving portion 163 are naturally disengaged. Therefore, when the seal cover 146 is largely rotated and displaced, it is not necessary to manually remove the seal cutter 148 that protrudes from the sticking portions 142 and 144 and cuts the seal seal S from the inside of the seal cover 146. It can be separated from the seal cover 146 in conjunction with the removal operation. As described above, the seal cutter 148 that cuts the seal seal S when the seal cover 146 is removed is separated from the seal cover 146 by the difference in the rotational displacement locus between the seal cover 146 and the seal cutter 148. There is no need to remove it from the seal cover 146 when reusing.

  The first attachment receiving portion 172 and the second attachment receiving portion 173 into which the cover attaching portions 168 and 169 of the seal cover 146 are fitted are the base member 62 (base caulking component 90) and the cover member 64 (cover caulking component 94). Are combined with the components provided on the base member 62 side (base notch portion 172a, base recess portion 173a) and the components provided on the cover member 64 side (cover notch portion 172b, lower cover wall 127). Front end surface). That is, if the base member 62 and the cover member 64 are not combined, the mounting receiving portions 172 and 173 are not completed. Therefore, the seal cover 162 is mistakenly attached to the component parts of the mounting receiving portions 172 and 173 in the base member 62 and the cover member 64 by mistake. Even when it is attached, the seal cover 162 can be removed.

  The caulking means includes two caulking sets including a base connecting portion 92 and a cover connecting portion 96, and the caulking set in the caulking state is broken by the connecting support pieces 110 and 130 and the connecting piece 122 to be removed. After the substrate case 32 is opened for an appropriate reason such as maintenance of the main control board 31, the base member 62 and the cover member 64 may be connected inseparably using the remaining caulking set. For this purpose, the substrate case 32 is provided with a spare lock member 100, and this spare lock member 100 is held by a member holding part 156 provided in the cover sticking part 144, and the base sticking part 142 and It is accommodated between the cover sticking parts 144. Thus, the spare lock member 100 is accommodated between the base sticking portion 142 of the base member 62 and the cover sticking portion 144 of the cover member 64, which are configured so as not to be separated by the caulking means, Since it is enclosed inside the seal cover 146 that covers the adhering portions 142 and 144 and is attached to the base member 62 and the cover member 64 in an inseparable manner, the spare lock member 100 is removed and used for unauthorized modification. Such as fraud can be prevented. Even if the seal cover 146 is removed, since the spare lock member 100 cannot be accessed unless the substrate case 32 is opened, fraud can be hesitant.
