BEST MODE FOR CARRYING OUT THE INVENTION The best mode for carrying out the present invention will be described based on the drawings, divided into a first embodiment and a second embodiment.
(First embodiment)
1 to 9 show a first embodiment of the present invention.
(Substrate case 1)
A substrate case 1 according to the present embodiment is preferably a transparent, thin box-shaped storage box for storing a control board for controlling the operation of the gaming machine, and as shown in FIG. An upper case 10 and a lower case 20 as a main body.

  As shown in FIG. 2, the upper case 10 includes a surface plate 11 having elevations on four sides and a flange portion 12 projecting in a direction parallel to the surface plate 11 and having an opening on one surface. Is the body. The lower case 20 is a box having an opening on one surface, which includes a back plate 21 having elevations on four sides and a flange portion 22 projecting in a direction parallel to the back plate 21. The lower case 20 can fix the control board P (see FIG. 5) in a recess formed by the back plate 21 and four elevation surfaces. Although not particularly illustrated, the control board P is a printed board on which electronic components such as a CPU, a ROM, and a RAM are mounted. Then, by joining the surface of the upper case 10 with the opening and the surface of the lower case 20 with the opening, both the openings are closed and formed by the surface plate 11 of the upper case 10 and the four vertical surfaces. The control board P is accommodated in an internal space formed by the recessed portion and the recessed portion of the lower case 20.

Hereinafter, when the substrate case 1 is installed on a horizontal plane so that the lower case 20 is on the lower side (see FIGS. 5 and 6), the upper side is the “front side” and the lower side is the “rear side” "When the substrate case 1 is viewed from the front surface side (see FIG. 4), the side that becomes the upper, lower, left, and right sides is referred to as the" side surface side ".
A lower engagement portion 40 (see FIG. 2), which is a main body engagement portion for engaging the upper case 10, is formed on a portion (hereinafter referred to as a side surface portion) located on one side surface of the lower case 20. In addition, a lower screw boss 23, which is a main body fixing portion for attaching a screw Q (see FIG. 1) as a fixing member when the upper case 10 is fixed, is provided on the side surface portion opposite to the one side surface portion. It has been. On the other hand, an upper engaging portion 30 (see FIG. 2) is formed on one side surface portion of the upper case 10 as a lid engaging portion that can engage with the lower engaging portion 40 of the lower case 20. In addition, an upper screw boss 13 as a lid fixing portion corresponding to the lower screw boss 23 is provided on the side surface portion opposite to the one side surface portion. In the present embodiment, as shown in FIG. 2, the upper engagement portion 30 provided in the upper case 10 is a bearing portion 31, and the lower engagement portion 40 provided in the lower case 20 is a shaft portion 41. In the upper case 10 and the lower case 20, the side where the upper engaging portion 30 and the lower engaging portion 40 are provided (the left side in FIGS. 4 and 6) is the engaging side, and the upper screw bosses 13 and 23 are provided. The side (right side in FIGS. 4 and 6) is called the fixed side.

  As shown in FIGS. 2 and 5, the bearing portion 31 of the upper case 10 is two tongue pieces projecting from the end of the flange portion 12 on the engagement side toward the back surface side. It is formed in a substantially J shape in side view that curves toward the outer peripheral side. On the other hand, the flange portion 22 on the engagement side of the lower case 20 is formed with two rectangular openings 24 into which the bearing portions 31 can be inserted. A shaft portion 41 having a substantially semi-cylindrical diameter protruding upward is provided. The bearing 31 is formed with a rib 50 as an accidental closing prevention piece projecting toward the back surface side, and when the bearing 31 is engaged with the shaft 41 in the opening 24. A rib notch groove 25 for preventing the rib 50 from interfering with the rib 50 is formed. As shown in FIGS. 2 and 5, the rib 50 is a plate-like protrusion that protrudes from the lower end of the bearing portion 31 toward the rear surface side, and the tip end portion on the protruding side is formed in a semicircle in a side view. Yes. The operation of the rib 50 will be described later.

  When the substrate case 1 is formed by combining the upper case 10 and the lower case 20 having the above-mentioned configuration, first, as shown in FIG. The bearing portion 31 of the upper case 10 is inserted into the opening 24 of the lower case 20 from the front end portion while being inclined toward the side. At this time, the rib 50 is aligned with the position of the rib notch groove 25. Then, the curved portion of the bearing portion 31 is attached to the shaft portion 41 so that the shaft portion 41 and the bearing portion 31 are fitted, and the upper case 10 is rotated in the closing direction (direction in which the fixed portion approaches). When the upper case 10 and the lower case 20 are rotated until they come into contact with each other, as shown in FIG. 5, the curved portion of the bearing portion 31 wraps around the back side of the shaft portion 41 and moves to the shaft portion 41. The bearing 31 is in an appropriate position with respect to the shaft 41 by being locked. In this state, the upper case 10 is locked to the lower case 20 so as not to move to the surface side (upward) by the engagement of the shaft portion 41 and the bearing portion 31, and is engaged by the engagement of the bearing portion 31 and the opening 24. It is locked to the lower case 20 so as to be immovable also on the side surface side (up / down / left / right direction). Further, as shown in FIG. 3, the bearing portion 31 and the rib 50 are exposed through the opening 24 on the back surface side of the flange portion 22. Then, the back surface 12A of the flange portion 12 of the upper case 10 and the front surface 22A of the flange portion 22 of the lower case 20 are in contact with each other without a gap as shown in FIG. The screw hole 13A of the upper screw boss 13 and the screw hole 23A of the lower screw boss 23 are matched.

Then, the screw Q is screwed into the screw hole 23A of the lower screw boss 23 of the lower case 20 by screwing the screw Q into the screw hole 13A (see FIG. 2) of the upper screw boss 13 of the upper case 10, and the lower case 20 And the upper case 10 is closed. Thus, the internal space formed by the lower case 20 and the upper case 10 is closed, and the control board P is stored in the board case 1. The screw Q can be rotated in the screwing direction, but may be a one-way screw having a head shape that does not rotate in the reverse direction. In this case, the control board P cannot be taken out unless the screw Q or the board case 1 is destroyed.
Although not particularly shown, the board case 1 assembled as described above is attached to a predetermined position inside the gaming machine so that the board surface of the built-in control board P can be visually recognized. For example, in the case of a slot machine, when the front door is opened, the substrate surface is fixed at a position where the substrate surface can be viewed from the front, such as the back plate of the housing. In the case of a pachinko gaming machine, the front door is opened, such as the back side of the front door provided with a game board, and the board surface is fixed at a position where the board surface can be seen from the back side of the front door. In addition, predetermined measures are taken so as to prevent unauthorized opening by a seal seal or caulking, or to leave a trace of unauthorized opening.

(Rib 50)
Next, the operation of the rib 50 will be described.
As described above, when the shaft portion 41 and the bearing portion 31 are properly engaged with each other, as shown in FIG. 2 and FIG. It protrudes to the back surface side of 20, and does not prevent the flange portion 12 of the upper case 10 and the flange portion 22 of the lower case 20 from overlapping with no gap. However, when the shaft portion 41 and the bearing portion 31 are not properly engaged, for example, when the bearing portion 31 is not inserted into the opening 24 during the operation of the substrate case 1, FIG. 6B shows. As described above, the rib 50 contacts the shaft portion 41. That is, the rib 50 is on the shaft portion 41 so as to intersect the shaft portion 41. For this reason, a gap T is generated between the back surface 12A of the flange portion 12 of the upper case 10 and the front surface 22A of the flange portion 22 of the lower case 20. Even in this case, the screw boss 13 of the upper case 10 and the screw boss 23 of the lower case 20 are matched by matching the vertical center axes of the bearing portion 31 and the shaft portion 41 in the same manner as in proper engagement, and the screw Q is The screw holes 13A and 23A can be fixed.

  However, as shown in FIG. 7A, the gap T has a maximum length from the flange portion 22 of the shaft portion 41 and the length from the back surface 12A of the flange portion 12 to the tip portion of the rib 50. The length will be. In such a state, as shown in FIG. 6B, the surface of the upper case 10 appears to be clearly inclined with respect to the lower case 20, and the shaft portion 41 and the bearing portion 31 are not engaged. It can be confirmed at a glance. Therefore, even if the screw Q can be fixed to the screw holes 13A and 23A (the screw holes 3A and 23A match), the screw Q is attached in such a poorly engaged state. Can be prevented. When the rib 50 is not inserted into the rib notch groove 25, only the tip of the rib 50 enters the opening 24 as shown in FIG. However, in this case, unlike the case of FIG. 7A, the center axis in the vertical direction of the bearing portion 31 and the shaft portion 41 is shifted, and as a result, the side end portion on the fixed side of the upper case 10 is The screw holes 13A and 23A of the upper and lower screw bosses 13 and 23 do not match and the screw Q cannot be screwed in (because it may not lead to a closing error). . In other words, the rib 50 and the rib notch groove 25 also function as positioning means for properly inserting the bearing portion 31 into the opening 24. Then, although the screw boss 13 of the upper case 10 and the fixing side of the lower case 20 are in a fixable position, the engagement between the bearing portion 31 and the shaft portion 41 is inappropriate (in FIG. 7A). In such a case, the rib 50 exhibits its original function.

This will be described in comparison with a case having the same configuration as the above-described substrate case 1 but not having the rib 50. FIG. 8 shows a substrate case 100 according to a comparative example. The substrate case 100 includes an upper case 110 and a lower case 120. The bearing part 131 provided on the upper case 110 and the shaft part 141 provided on the lower case 120 are engaged with each other, and the end on the opposite side is engaged. The control board (not shown) can be accommodated by screwing.
In the assembly process of the substrate case 100 according to the comparative example, a poor engagement between the shaft portion 141 and the bearing portion 131 (the bearing portion 131 was not properly inserted into the opening 124 provided in the lower case 120) occurred. In this case, as shown in FIG. 9, the bearing portion 131 abuts on the shaft portion 141, and as shown in FIG. 8, the back surface 112 </ b> A of the flange portion 112 of the upper case 110 and the front surface 122 </ b> A of the flange portion 122 of the lower case 120. A gap t is generated between them. However, since the ribs 50 are not provided in the bearing part 131, the gap t is at most the protruding length of the shaft part 141 from the flange part 122 and the back surface 12A of the flange part 112 to the tip part of the bearing part 131. This is the length plus the length. With such a size, the inclination of the upper case 110 with respect to the lower case 120 is not so noticeable (in the example shown, the inclination angle is about half), and it is inadvertently overlooked and the screw is fixed as it is. It can happen.

On the other hand, according to the present embodiment, as shown in FIGS. 5 and 6, the rib 50 having a protruding length longer than the protruding length from the rear surface 12A of the flange portion 12 of the bearing portion 31 is provided. Thus, when the engagement between the shaft portion 41 and the bearing portion 31 is not appropriate, it can be made remarkable. As a result, the operator's attention is alerted, and a closing error that the upper case 10 and the lower case 20 are fixed by the screw Q with poor engagement can be prevented. When the screw Q is a one-way screw, the substrate case 1 must be destroyed once it is fixed, so that the presence of the rib 50 further increases.
In the above-described embodiment, the rib 50 may be provided on the shaft peripheral surface on the surface side of the shaft portion 41 over the length direction. Even if formed in this way, when the bearing portion 31 is not engaged with the shaft portion 41 and is in contact with the shaft portion 41, the surface of the upper case 10 is greatly inclined, so that the engagement failure becomes remarkable. Can do. Alternatively, the rib 50 may be provided on both the bearing portion 31 and the shaft portion 41.

In the above-described embodiment, the bearing portion 31 is provided as the upper engagement portion 30 and the shaft portion 41 is provided as the lower engagement portion 40. Although not particularly illustrated, the upper engagement portion 30 is provided as the shaft portion and the lower engagement portion. The joint portion 40 may be a bearing portion. Also in this case, the rib 50 may be provided on the shaft portion, the bearing portion, or both. In short, the rib 50 is a surface on the opposite side of the surface that comes into contact with each other when the shaft portion and the bearing portion are properly fitted, and on the front and back sides of the upper case 10 or the lower case 20. What is necessary is just to be provided in the surface located in either direction toward the joining partner.
Furthermore, the shape of the upper case 10 and the lower case 20 is not limited to a box shape, and for example, one of the upper case 10 and the lower case 20 may be formed in a plate shape. Further, the control board P may be fixed to the upper case 10. Further, the fixing of the upper case 10 and the lower case 20 is not limited to the one using screws, but pins or rivets may be used, and the engaging portion formed on the upper case 10 and the lower part may be used without using such fixing members. The engaged portion formed on the case 20 may be fixed by fitting. The shapes of the bearing portion 31 and the shaft portion 41 are examples, and the upper case 10 or the lower case is in a state where the upper engagement portion 30 of the upper case 10 and the lower engagement portion 40 of the lower case 20 are engaged. Any shape can be used as long as it is formed so that the upper case 10 and the lower case 20 can be fixed and joined together (a state where the screw holes are matched) by rotating any one of 20 May be.

(Second embodiment)
10 to 19 show a second embodiment of the present invention.
The basic configuration of the substrate case 1 according to the second embodiment is substantially the same as that of the first embodiment. In the present embodiment, the upper case 10 is covered on the lower case 20, and the upper case 10 is covered. The case 10 is slid and fixed to the lower case 20.
(Substrate case 1)
As shown in FIG. 10, the substrate case 1 according to the second embodiment includes an upper case 10 and a lower case 20. The upper case 10 is almost the same as in the first embodiment. As shown in FIG. 11, the lower case 20 includes a back plate 21 and a flange portion 22, and on the surface of the flange portion 22, a rectangular frame-like standing wall 26 erected on the front surface side is provided. Yes. The standing wall 26 has an internal dimension that can accommodate the flange portion 12 of the upper case 10. And, on the side surface portion on the engagement side of the upper case 10, two tongue-like insertion pieces 32 protruding from the end of the flange portion 12 toward the side are formed, and the lower case Two rectangular insertion grooves 42 into which the insertion pieces 32 can be inserted are formed in the standing wall 26 on the 20 engagement side. That is, the upper engagement portion 30 provided in the upper case 10 is the insertion piece 32, and the lower engagement portion 40 provided in the lower case 20 is the insertion groove 42. Further, a rib 50 is formed on the back surface of the insertion piece 32, and the vertical surface of the back plate 21 of the lower case 20 is communicated with the insertion groove 42 as shown in FIGS. A rib notch groove 27 is formed so that the rib 50 does not interfere when the insertion piece 32 is inserted into the insertion groove. As shown in FIGS. 14 and 16, the rib 50 is a rectangular plate-like protrusion that protrudes from the lower surface of the insertion piece 32 toward the back surface side, and extends in a direction perpendicular to the protruding direction of the insertion piece 32. It is formed so that the plate surface faces.

When the substrate case 1 is formed by combining the upper case 10 and the lower case 20 having the above configuration, first, the upper case 10 is positioned above the lower case 20 (see FIG. 11), and the standing wall 26 of the lower case 20 is placed. The flange portion 12 on the engagement side of the upper case 10 is fitted therein, and the insertion piece 32 is inserted into the insertion groove 42 formed in the standing wall 26 from the tip portion. At this time, the flange portion 12 on the fixed side of the upper case 10 may overlap the standing wall 26. The rib 50 is aligned with the position of the rib notch groove 27. Then, the upper case 10 is slid to the engagement side inside the standing wall 26.
Slide the upper case 10 into the upright wall 26 until the end of the flange 12 on the engagement side of the upper case 10 contacts the inner surface of the upright wall 26 on the engagement side. It is in an appropriate position with respect to the insertion groove 42. In this state, the upper case 10 is locked to the lower case 20 so as not to move to the surface side by the engagement of the insertion piece 32 and the insertion groove 42. Moreover, as shown in FIG. 13, the front-end | tip (projection side) of the insertion piece 32 is exposed from the insertion groove 42, and as shown in FIG.13 and FIG.15 (A), on the back surface side of the flange part 22, The rib 50 is exposed through the notch groove 27 for ribs. Further, the surface of the flange portion 12 of the upper case 10 and the upper end portion of the standing wall 26 of the lower case 20 are substantially flush, and the back surface 12A of the flange portion 12 of the upper case 10 and the surface 22A of the flange portion 22 of the lower case 20 are Contact with no gap. The screw hole 13A of the upper screw boss 13 and the screw hole 23A of the lower screw boss 23 are matched.

When the upper case 10 and the lower case 20 are fixed by screwing the screw Q from the screw hole 13A of the upper screw boss 13, the inner space is closed and the control board P is accommodated.
(Rib 50)
Next, the operation of the rib 50 will be described with reference to FIGS.
When the insertion piece 32 and the insertion groove 42 are properly engaged with each other, as shown in FIGS. 13 and 15A, the rib 50 is connected to the back surface of the lower case 20 via the rib notch groove 27. The flange portion 12 of the upper case 10 and the flange portion 22 of the lower case 20 are not prevented from overlapping with no gap. However, when the insertion piece 32 and the insertion groove 42 are not properly engaged, for example, when the insertion piece 32 is not inserted into the insertion groove 42 during the operation of the substrate case 1, FIG. As shown, the rib 50 contacts the surface 26A of the standing wall 26 of the lower case 20. That is, the rib 50 is on the standing wall 26 so as to intersect the standing wall 26. For this reason, as shown in FIG. 16, a gap T ′ is generated between the back surface 12A of the flange portion 12 of the upper case 10 and the surface 26A of the standing wall 26 of the lower case 20. Even in this case, as in the case of proper engagement, the screw boss 13 of the upper case 10 and the screw boss 23 of the lower case 20 match, and the screw Q can be fixed to the screw holes 13A and 23A.

However, the gap T ′ is the maximum length from the back surface 12A of the flange portion 12 to the tip portion of the rib 50. In such a state, as shown in FIG. 15B, the surface of the upper case 10 appears to be clearly inclined with respect to the lower case 20, and the insertion piece 32 and the insertion groove 42 are not engaged. This can be confirmed at a glance. Therefore, even if the screw holes 13A and 23A of the upper and lower screw bosses 13 and 24 are matched, it is possible to prevent the screw Q from being attached in such a poorly engaged state. .
This will be described in comparison with a case having the same configuration as the above-described substrate case 1 but not having the rib 50. FIG. 17 shows a substrate case 100 according to a comparative example. The substrate case 100 includes an upper case 110 and a lower case 120, and the insertion piece 132 provided on the upper case 110 is inserted into the insertion groove 142 provided on the standing wall 126 of the lower case 120, so that the opposite side A control board (not shown) can be accommodated by screwing the end.

  In the assembly process of the substrate case 100 according to the comparative example, when a poor engagement between the insertion piece 132 and the insertion groove 142 occurs (the insertion piece 132 was not properly inserted into the insertion groove 142), 17, the lower surface of the insertion piece 132 abuts on the upper end portion 126 </ b> A of the upright wall 126, and the flange portion 112 on the engagement side of the upper case 110 serves as the upright wall of the lower case 120 as shown in FIGS. 18 and 19. Exposed from 26. However, there is no gap between the back surface 112A of the flange portion 112 of the upper case 110 and the upper end portion 126A of the standing wall 126 of the lower case 120. In addition, since the ratio of the height of the standing wall 126 to the length and width of the lower case 120 is small, the inclination of the upper case 110 with respect to the lower case 120 is not so remarkable (in the example shown, the inclination angle is about half) There is a possibility that you may accidentally overlook and fix the screw.

On the other hand, according to the present embodiment, as shown in FIGS. 14 and 16, the rib 50 having a protruding length substantially equal to the protruding length from the surface of the flange portion 12 of the standing wall 26 is provided. Therefore, when the engagement between the insertion piece 32 and the insertion groove 42 is not appropriate, it can be made remarkable. As a result, the operator's attention is alerted, and a closing error that the upper case 10 and the lower case 20 are fixed by the screw Q with poor engagement can be prevented. When the screw Q is a one-way screw, the substrate case 1 must be destroyed once it is fixed, so that the presence of the rib 50 further increases.
In the above-described embodiment, the rib 50 may be provided on the surface 26A of the standing wall 26 and above the insertion groove 42. Even if formed in this way, when the insertion piece 32 is not inserted into the insertion groove 42 and is in contact with the standing wall 26, the surface 26A of the standing wall 26 and the back surface 12A of the flange portion 12 of the upper case 10 A gap is formed between the upper case 10 and the surface of the upper case 10 is greatly inclined. Alternatively, the rib 50 may be provided on both the standing wall 26 and the insertion piece 32.

  In the above-described embodiment, the insertion piece 32 is provided as the upper engagement portion 30, and the insertion groove 42 is provided as the lower engagement portion 40. However, although not particularly illustrated, the upper engagement portion 30 is provided as the upper case 10. The lower engagement portion 40 may be an insertion piece provided on the inner side of the standing wall 26 of the lower case 20 (center side of the lower case 20). In this case, the rib 50 can be provided on the surface of the insertion piece or on the back surface of the upper case 10. In the former case, a groove through which the rib 50 can pass is provided in the insertion groove, and in the latter case, a recess capable of accommodating the rib 50 may be provided on the surface of the lower case 20. Alternatively, the rib 50 is provided on both the surface of the insertion piece and the back surface of the upper case 10, and a groove through which the rib 50 of the upper case 10 can pass is provided in the insertion groove, and the insertion piece is provided on the surface of the lower case 20. A recess that can accommodate the rib 50 may be provided. In short, the rib 50 is an insertion piece, or any surface of the upper case 10 or the lower case 20 with which the insertion piece abuts when the insertion piece and the insertion groove are not properly engaged. In the case where the upper engagement portion 30 and the lower engagement portion 40 are not properly engaged with each other, a clearance may be provided between the upper case 10 and the lower case 20. That's fine.

Furthermore, the shapes of the insertion piece 32 and the insertion groove 42 are merely examples, and the upper case 10 and the lower case 20 are slid together to move the upper case 10 below the upper engagement portion 30 and the lower case 20. As long as the engaging part 40 is engaged and the upper case 10 and the lower case 20 are formed so that they can be fixed together (a state in which the screw holes are matched), any shape can be obtained. Also good. The shapes of the upper case 10 and the lower case 20 and the manner of the fixing portion are not limited to the illustrated example as described in the first embodiment.
The present invention is not limited to a substrate case for storing a control board of a gaming machine, but can be used for any storage box that stores a stored item therein and engages and fixes the main body and the lid. It may be a storage box.
