It fits between the positioning protrusions 120, 120. Further, in relation to the first end face wall 203, the first positioning protrusion 120 (Y1) of the cover mounting portion 105 is formed in a recess between the third lock engaging piece 205 and the first restricting portion 212 (see FIG. 11 and the like). The first positioning protrusion 120 of the direction side is fitted, and the first positioning protrusion of the cover mounting portion 105 is formed in the recess between the third lock engaging piece 205 and the second restricting portion 213 (see FIG. 11 and the like). 120 (first positioning protrusion 120 on the Y2 direction side) is fitted.

  Further, in relation to the second end surface wall 204 and the second end surface portion 119 of the cover mounting portion 105, the fourth lock engaging piece 215 of the seal cover 200 is connected to the pair of second positioning protrusions 122 and 122 of the cover mounting portion 105. It fits between. Further, in relation to the second end wall 204, the second positioning projection 122 (Y1) of the cover mounting portion 105 is formed in a recess between the fourth lock engaging piece 215 and the third restricting portion 222 (see FIG. 11 and the like). The second positioning projection 122 of the direction side is fitted, and the second positioning projection of the cover mounting portion 105 is inserted into the recess between the fourth lock engaging piece 215 and the fourth restricting portion 223 (see FIG. 11 and the like). 122 (second positioning protrusion 122 on the Y2 direction side) is fitted. The seal cover 200 is guided by the first end face wall 203, the first end face portion 118, the second end face wall 204, and the second end face portion 119, and is slid downward.

  When the seal cover 200 fitted to the cover mounting portion 105 (on the upper surface portion 116 and the interference piece 68) is slid downward, the third lock engagement piece 205 is locked and engaged with the third engagement recess 121. The fourth lock engagement piece 215 is locked and engaged with the fourth engagement recess 123. As a result, as shown in FIGS. 3 and 20B, the seal cover 200 is coupled to the cover mounting portion 105 (to the upper surface portion 116 and the interference piece 68) inseparably from each other (lock coupling). Thereby, the main substrate case 1 is in a sealed state, and the sealed state is maintained thereafter.

In this case, the base body 30 and the cover body 100 are lock-coupled to each other, and the seal cover 200 is lock-coupled to the interference piece 68 of the base body 30 and the upper surface portion 116 of the cover body 100. In other words, when the main substrate case 1 is sealed, the lock coupling is doubled. As a result, the sealing reliability of the main substrate case 1 can be kept high.
Further, if the base body 30 and the cover body 100 are not in the fitted state, the interference piece 68 becomes an obstacle and the seal cover 200 cannot be mounted on the cover mounting portion 105. Therefore, if the seal cover 200 is attached to the base body 30 and the cover body 100, the base body 30 and the cover body 100 are in a coupled state, and both are locked and coupled. Therefore, the reliability of sealing the main substrate case 1 can be kept higher.

  Further, if the relative position of the base body 30 and the cover body 100 is not the fitting position, the seal cover 200 cannot be attached. Conversely, if the seal cover 200 is attached to the cover attachment portion 105, This means that a state in which the relative position of the base body 30 and the cover body 100 is in the fitting position, that is, a state in which both are lock-coupled, is guaranteed. Therefore, the reliability of sealing the main substrate case 1 can be kept even higher.

  Next, the case where the main board case 1 is opened for inspection or the like will be described with reference to FIGS. 17 to 20 again. When opening the main substrate case 1, first, the seal cover 200 is removed from the cover mounting portion 105 (from the upper surface portion 116 and the interference piece 68). Specifically, the third lock that breaks the ninth to eleventh fracture connecting portions 209 to 211 (see FIG. 12 and the like) with a cutting tool (not shown) and is locked to the third engagement recess 121. The engagement piece 205 is removed (detached) from the upper surface wall 201 of the seal cover 200. In addition, the fourth lock engagement piece that breaks the twelfth to fourteenth fracture connecting portions 219 to 221 (see FIG. 12 and the like) with a cutting tool (not shown) and locks the fourth engagement recess 123. 215 is removed (detached) from the upper surface wall 201 of the seal cover 200. As a result, the lock coupling of the seal cover 200 to the cover mounting portion 105 (to the upper surface portion 116 and the interference piece 68) is released. Then, the seal cover 200 can be removed from the cover mounting portion 105 (from the upper surface portion 116 and the interference piece 68) by sliding the seal cover 200 upward. In this state, the third and fourth lock engaging pieces 205 and 215 remain attached to the first and second end surface portions 118 and 119 of the cover mounting portion 105, respectively.

Next, the cover body 100 and the base body 30 are separated. Specifically, the first lock engagement piece 50, which breaks the first to fourth fracture connecting portions 46 to 49 (see FIG. 6) with a cutting tool and is locked to the first engagement recess 124, 50 is removed (separated) from the base body side wall 32 together with the first separation side wall 40.
Thereby, the lock coupling | bonding of the base body 30 and the cover body 100 is cancelled | released. At this time, the main board case 1 is ready to be opened. Then, when a force is applied to the base body 30 and the cover body 100 so that the cover body 100 is relatively directed to the fitting position, the seal stuck across the cover mounting portion 105 and the interference piece 68 of the base body 30 While the seal (not shown) is broken, the cover body 100 slides to the fitting position. Thereafter, the base body 30 and the cover body 100 can be separated by moving the cover body 100 upward with respect to the base body 30. In this state, the first lock engaging pieces 50, 50 remain attached to the cover body side wall 107 of the cover body 100 together with the first separation side wall 40.

  FIG. 21 is a view of the base body 30 after opening the main board case 1 as viewed from the arrow XXI shown in FIG. 5A. Since the base body 30 is formed using a transparent resin material, when the first lock engagement piece 50 is removed from the base body 30, the first to fourth fracture connecting portions 46 to 49 (see also FIG. 6). In FIG. 21, a trace (in FIG. 21, the trace portion is indicated by hatching) remains such that the fracture surface is discolored white. As described above, the first to fourth destruction connecting portions 46 to 49 are provided so as to be visible from the back side of the game board 5 when the game board 5 is attached to the main board case 1. Further, as described above, the first to fourth fracture connecting portions 46 to 49 are the outer end edges of the first and second separation side walls 40 and 41 and the first, second, third and fourth coupling side walls. It protrudes outward, that is, in the X1 direction side from the outer end edges of 37, 38, 39, and 17. Therefore, the operator can confirm from the back side of the game board 5 whether or not there is a trace that the first lock engagement piece 50 has been removed from the first to fourth destruction connecting portions 46 to 49. Thereby, the operator can identify whether or not the first lock engagement piece 50 has been removed, that is, whether or not the main board case 1 has been opened once.

Next, the case where the main board case 1 is resealed will be described.
When the main substrate case 1 is resealed (in the second sealing), the spacer 170 is taken out from the spacer storage portion 127 and attached to the spacer mounting portion 126 as shown in FIGS. 7A and 7B. FIG. 22 is a view of the cover body 100 in a state where the spacer 170 is attached to the spacer mounting portion 126, as viewed from the arrow IX shown in FIG.

  Then, as in the case of the first sealing operation, the cover body 100 is turned upside down from the state shown in FIGS. 7A, 7B and 8, and the relative positions of the cover body 100 and the base body 30 are fitted. The operator aligns the cover body 100 and the base body 30 up and down while visually aligning them so as to be in the position. Thereby, as shown in FIG. 17, the base body 30 and the cover body 100 are positioned in the fitting position.

  FIG. 23 is a cross-sectional view of the main part showing the second sealing operation of the main substrate case 1, and shows a coupled state of the base body 30 and the cover body 100. When the cover body 100 positioned at the fitting position is slid toward the coupling position, the cover body side wall 107 is brought close to the base body side wall 32. Then, each second lock engagement piece 60 is inserted into the corresponding passage recess 125 and the second engagement recess 174, and the second lock engagement claws 62 are located on both sides of the second engagement recess 174. Engage with. As a result, the second lock engagement piece 60 is locked to the second engagement recess 174, and as a result, the base body 30 and the cover body 100 are coupled to each other so as not to be separated (lock coupling).

  Next, the seal cover 200 is attached to the cover mounting portion 105 (to the upper surface portion 116 and the interference piece 68). As in the case of the first sealing operation, the seal cover 200 is attached to the cover mounting part 105 from the upper side with respect to the cover mounting part 105 (on the upper surface part 116 and the interference piece 68). Is done. In a state where the seal cover 200 is mounted on the cover mounting portion 105 (on the upper surface portion 116 and the interference piece 68), the upper surface wall 201 covers the upper surface wall 201 of the cover mounting portion 105, and the side wall 202 covers the outer surface of the interference piece 68. The first end surface wall 203 covers the first end surface portion 118 of the cover mounting portion 105, and the second end surface wall 204 covers the second end surface portion 119 of the cover mounting portion 105. Thereby, the main board case 1 can be resealed.

  In this second sealing (resealing), the sealing seal (not shown) remains broken, and the base body 30 and the cover body 100 are not sealed by the sealing seal. Since the seal cover 200 is formed transparently as described above, it can be easily seen from the outside of the main board case 1 whether or not the seal seal is broken. As a result, the operator seals whether the main board case 1 has not been opened yet (in the first sealed state) or has been opened once (in the second sealed state). It is possible to easily grasp without opening the cover 200.

By mounting the seal cover 200 on the cover mounting portion 105, it is ensured that the relative position of the base body 30 and the cover body 100 is in the fitting position, that is, the two are locked together. . Therefore, the reliability of sealing the main substrate case 1 can be kept even higher.
When the main board case 1 is re-sealed, the second lock member that breaks the fifth to eighth breakage connecting portions 53 to 56 (see FIG. 6) and locks with the second engagement recess 174. The combined piece 60 is removed (separated) from the base body side wall 32 together with the second separation side wall 41. Thereby, the lock coupling | bonding of the base body 30 and the cover body 100 is cancelled | released, and the main board | substrate case 1 will be in the state which can be opened. Then, after sliding the cover body 100 toward the fitting position, the cover body 100 can be separated by moving the cover body 100 upward with respect to the base body 30. In this state, the second lock engaging pieces 60, 60 are still attached to the cover body side wall 107 of the cover body 100 together with the second separation side wall 41.

As described above, according to this embodiment, the main substrate case 1 can be sealed with a simple operation procedure while enabling the main substrate case 1 to be resealed at least once.
Further, the base body 30 and the cover body 100 can be locked together in both of the two sealings of the main substrate case 1. Thereby, the reliability of sealing can be kept high.

Further, the main substrate case 1 (cover body 100) is provided with a spacer accommodating portion 127, and the spacer 170 that is detached from the spacer mounting portion 126 can be accommodated in the spacer accommodating portion 127. Therefore, it is not necessary to store the spacer 170 separately from the substrate case during the first sealing operation.
As mentioned above, although one Embodiment of this invention was described, this invention can also be implemented with another form.

For example, in the above description, when the main substrate case 1 is sealed (first and second sealing operations), the main substrate 21 is first set on the base body 30 and the main substrate 21 is set. The case where the cover body 100 is fitted to the base body 30 and the both are coupled is taken up.
However, first, the main substrate 21 may be set on the cover body 100, and the base body 30 may be fitted to the cover body 100 after the main substrate 21 is set, so that the two are coupled. In this case, the state shown in FIG. 4 does not exist. The sealing of the main substrate 21 in this case will be specifically described.

First, the main board 21 is screwed to the cover body 100. In this case, as in the case where the main board 21 is first attached to the base body 30, one main surface of the main board 21 (the upper surface shown in FIG. 4; the main surface on which the electronic component 25, the connectors 26, 27, etc. are mounted). The main board 21 is fixed to the cover body 100 with screws in a state in which is directed toward the bottom wall 106 of the cover body 100.
When the cover body 100 is screwed to the main substrate 21, the vertical direction during the sealing operation is different from the case where the main substrate 21 is first attached to the base body 30. In other words, the cover body 100 is set so that the upper side shown in FIGS. 7A, 7B and 8 is the upper side when sealed, and the cover body 100 in the state shown in FIGS. The substrate 21 is attached. Thereby, workability | operativity at the time of screwing can be improved.

  Further, the main board 21 is screwed to the cover body 100 with one main surface (the upper surface shown in FIG. 4) of the main board 21 facing the bottom wall 106 of the cover body 100. Therefore, after the board 21 is attached to the cover body 100, the electronic component 25, the connectors 26, 27, and the like mounted on one main surface of the main board 21 are covered with the main board 21 main body. Therefore, it is possible to protect the electronic component 25, the connectors 26, 27, and the like at an early stage of the sealing operation, which is caused by the operation for fitting and coupling the cover body 100 and the base body 30. The influence on the electronic component 25 and the connectors 26 and 27 can be prevented.

  The cover body 100 after the main substrate 21 is fixed can be fitted and coupled to the base body 30 in various postures. For example, as in the case where the main board 21 is attached to the base body 30 previously, the cover body 100 is inverted from the state shown in FIGS. 7A, 7B and 8 (turned upside down), The base body 30 may be fitted and connected, or the base body 30 is inverted from the state shown in FIGS. 5A and 5B while the cover body 100 is in the state shown in FIGS. 7A, 7B and 8. Thus, the cover body 100 and the base body 30 may be fitted and coupled.

Still other embodiments can be implemented.
For example, the first lock engagement pieces 50 and 50 may be a single lock engagement piece instead of a pair of lock engagement pieces. Similarly, the second lock engagement pieces 60 and 60 may be a single lock engagement piece instead of a pair of lock engagement pieces.
Further, the seal cover 200 may not be configured to be lockable and connectable to the base body 30 and the cover body 100. That is, the seal cover 200 may only be configured to be attached to the base body 30 and the cover body 100 that are in the coupling position. Furthermore, a configuration in which the seal cover 200 is not provided may be employed.

Moreover, the base body 30 and the cover body 100 are not restricted to the structure positioned in a fitting position. You may slide at least one of the base body 30 and the cover body 100 between a fitting position and a coupling position, without positioning to a fitting position.
Further, the spacer storage portion 127 can be provided not on the cover body 100 but on the base body 30. Further, the spacer storage portion 127 may not be provided on either the base body 30 or the cover body 100.

The spacer 170 may be colored in a predetermined color (that is, a color that is not transparent). Since both the base body 30 and the cover body 100 are formed transparently, the spacer 170 can be easily visually recognized from the outside of the main board case 1, and whether or not the spacer 170 is in the mounting position is determined. 1 can be grasped without removing it from the game board 5.
In addition, in the sealed state of the main substrate case 1 (including the above-described combined state), a part of the surface where the base body 30 and the cover body 100 are flush with each other is provided. The stamp straddling may be formed by, for example, laser marking. For example, as described above, in the coupled state of the base body 30 and the cover body 100, the upper surface 82 of the projecting piece 81 and the bottom surface of the bottom wall 106 of the main body 102 are flush with each other. A portion straddling the upper surface 82 and the bottom surface of the bottom wall 106 can be used as a marking location, and the location can be marked.

  In this case, the marking formed on the base body 30 (for example, the upper surface 82 of the projecting piece 81) and the marking formed on the cover body 100 (for example, the bottom surface of the bottom wall 106) function as index marks. Further, when the marking is formed by laser marking, the base body 30 and the cover body 100 may be joined by marking marking. In this case, the joining of the base body 30 and the cover body 100 and the marking can be realized together.

In addition, the main board case 1 (main board 21) has been described as an example of a configuration in which the main board case 1 (main board 21) is attached to the back surface of the game board 5. The structure attached to a position may be sufficient.
Furthermore, in the above description, the case where the base body 30 is placed below and the cover body 100 is stacked from above is described as an example. However, various aspects of attaching the cover body 100 to the base body 30 can be considered. That is, the cover body 100 may be stacked on the base body 30 placed on the upper side, or the cover body 100 may be stacked on the base body 30 arranged in a vertical direction (the base plate 31 extends vertically). There may be.

Moreover, although the example applied to the pachinko machine as the gaming machine 80 is shown in the above-described embodiment, it is needless to say that the present invention can be applied to other gaming machines such as a pachislot machine.
In addition, various design changes can be made within the scope of matters described in the claims.
