The holding column 12c is formed on the inner side in the width direction with a distance s away from the holding column 12d, and the depth position is a position separated from the rear wall surface 12b by the interval u similarly to the holding column 12d. The pair of wide portions 12c1 and 12c1 on both outer sides in the depth direction of the holding column 12c are formed to have a width r.

  The holding column 12e is formed so as to be substantially L-shaped when viewed from above, and is connected to the back wall surface 12b at the back end. Then, the front side is bent inward in the width direction, and the bent tip and the holding column 12c are formed at positions separated by a distance s. The holding column 12f is formed so as to have a substantially crank shape when viewed from above, and is formed at a position where the shortest distance from the holding column 12c is the interval s. The holding columns 12e and 12f are formed at positions spaced apart from the facing side wall surface 12b in the width direction by a distance t.

  Next, the retaining piece mounted inside the box portion 12 constituting the sealing portion 70a will be described. FIG. 7 shows the retaining piece as viewed from an oblique direction. In the same figure, the retaining piece 40 has a frame portion 40c formed in a rectangular frame shape, and a window portion 40d surrounded by four sides is formed in the frame portion 40c. The retaining piece 40 is entirely colored red by applying a red paint. The width of the window portion 40d is slightly wider than the width r, the thickness is slightly thinner than the interval u, and the height is h. The retaining piece 40 is made of synthetic resin, and a substantially plate-shaped retaining portion 41 is extended from one side of the frame portion 40c at a substantially right angle to the frame portion 40c.

  The retaining portion 41 includes a substantially plate-shaped retaining plate 41a and a retaining tip portion 41b whose tip is widened inward. The retaining plate 41a is formed to be slightly thinner than the interval s, and a retaining tip 41b is formed at the tip. The stopper tip 41b is formed to be slightly thinner than the interval u, and a stopper guide surface 41b1 is formed on the inner side of the stopper tip 41b. The stopper guide surface 41b1 is inclined so that the width of the tip gradually becomes narrower. . An end of the retaining guide surface 41b1 on the frame portion 40c side is connected to a retaining surface 41b2 orthogonal to the retaining plate 41a.

  On the other hand, a restricting portion 42 that is substantially parallel to the retaining plate 41a is extended from the side of the frame 40c that faces the side where the retaining portion 41 is extended. The restricting portion 42 is composed of a restricting rod 42a formed in a substantially rod shape and a restricting tip portion 42b that protrudes inwardly, and the distance between the restricting rod 42a and the retaining plate 41a is slightly larger than the width r. Is formed. The thickness of the regulating rod 42a is formed slightly thinner than the interval s. The restricting tip portion 42b includes a restricting guide surface 42b1 whose height decreases as it reaches the tip, and the thickness of the restricting tip portion 42b is slightly thinner than the interval u. The retaining portion 41 and the restricting portion 42 are formed so that the lower ends are at the same height, and the tip is also formed at the same position. In addition, the surface facing the inner side of the regulation rod 42a is defined as a first regulation surface 42a1, and the surface that faces the frame portion 40c and is orthogonal to the regulation rod 42a at the inner projecting portion of the regulation tip portion 42b is defined as the second regulation surface 42b2. It shall represent.

  Next, the protection member mounted inside the box part 12 constituting the sealing part 70a will be described. FIG. 8 shows the protective member 50 as viewed from an oblique direction. In the figure, the protective member 50 is formed in a substantially U shape by bending a metal plate having a thickness smaller than the interval t. The protection member 50 has two side plates 50a and 50a that are identical and parallel to each other, and the side plates 50a and 50a are connected by a bottom plate 50b at the lower end. The side plates 50a, 50a and the bottom plate 50b are bent so as to be orthogonal to each other. A notch 50c having a predetermined shape is formed in the bottom plate 50b.

  By configuring the box portion 12, the retaining piece 40, and the protection member 50 as described above, the retaining portion 40 and the protection member 50 can be attached to the box portion 12. FIG. 9 shows a state where the retaining piece 40 is attached to the box portion 12. In the figure, a retaining piece 40 is inserted from above so as to surround the holding column 12 c inside the box portion 12. That is, the retaining plate 41a and the restricting portion 42, which are formed slightly larger than the pair of wide portions 12c1 and 12c1 of the holding column 12c, hold the holding column 12c from the outside in the width direction.

  At that time, since the thickness of the retaining plate 41a is slightly smaller than the interval s between the retaining column 12c and the retaining column 12d, the retaining plate 41a, the retaining column 12c, and the retaining column 12d do not interfere with each other. . Similarly, since the thickness of the regulating rod 42a is slightly smaller than the interval s between the holding column 12c and the holding columns 12e, 12f, the regulating rod 42a, the holding column 12c, and the holding columns 12e, 12f interfere with each other. There is nothing. On the other hand, the thicknesses of the retaining tip portion 41b and the restricting tip portion 42b are formed slightly smaller than the distance u between the holding column 12c and the rear wall surface 12b, so that the retaining tip portion 41b and the restricting tip portion 42b are formed by the holding pillar 12c. And the rear wall surface 12b.

  In this manner, the retaining piece 40 is inserted into each gap formed by the holding pillars 12c to 12f and the wall surface 12b in the box portion 12 and is not particularly fixed by engagement or the like, and thus can be freely attached and detached. . In FIG. 9, the retaining piece 40 is attached so that the frame portion 40 c is oriented toward the front side, and the retaining tip portion 41 b and the regulating tip portion 42 b are oriented in the back. It shall be called the second wearing state.

  FIG. 10 shows a first mounting state in which the retaining piece 40 is mounted on the box portion 12 and is different from the second mounting state. In the figure, similarly to the second mounting state, the retaining piece 40 is inserted into each gap formed by the holding pillars 12c to 12f and the wall surface 12b in the box portion 12. However, it is mounted so that the frame portion 40c is oriented to the back, and the retaining tip portion 41b and the regulating tip portion 42b are oriented to the front side. In this first mounting state, the frame portion 40c is inserted into the gap between the holding column 12c and the rear wall surface 12b, but the thickness of the frame portion 40c is also determined from the interval u between the holding column 12c and the rear wall surface 12b. Since it is formed slightly small, it can be inserted without interference. Even in the first mounting state, the retaining piece 40 is not particularly fixed by engagement or the like, so that the retaining piece 40 can be freely attached and detached. That is, the retaining piece 40 can be freely attached to and detached from the first and second mounting states in the box portion 12 having an upper opening. In addition, since it is sufficient to reverse the retaining piece 40, it is possible to easily switch between the first mounting state and the second mounting state.

  On the other hand, in FIG. 10, the protection member 50 is mounted inside the box portion 12. Since the width of the bottom plate 50b in the protective member 50 is slightly smaller than the width inside the box portion 12, the side plates 50a and 50a that are orthogonal to each other at both ends of the bottom plate 50b that contacts the bottom surface 12a of the box portion 12 are used. Are in contact with the side wall surfaces 12b, 12b of the box portion 12 from the inside. Since the interval t between the holding columns 12d to 12f and the side wall surfaces 12b and 12b is larger than the thickness of the side plates 50a and 50a, the holding columns 12d to 12f and the side wall surfaces 12b and 12b are protected without interference. The member 50 can be attached. Since the predetermined cutout 50c is formed in the bottom surface plate 50b, the bottom surface plate 50b and the holding pillars 12c to 12f do not interfere with each other. When the rear end of the side plates 50a, 50a reaches the rear wall surface 12b, the end surface of the bottom plate 50b where the notch 50c is formed is formed so as to reach the holding columns 12c, 12d, 12f. ing.

  Even when the protection member 50 is mounted, the protection member 50 is not particularly fixed by engagement or the like, so that the protection member 50 can be freely attached and detached. The protective member 50 can be attached to the box portion 12 in both the first and second attachment states of the retaining piece 40 and can be attached to the box portion 12 even when the retaining piece 40 is not attached.

  FIG. 11 shows one of the lid plates 22 formed by extending the lid body portion 24 of the lid member 20 from the back, and FIG. 12 shows one of the lid plates as seen from the outside in the width direction. FIG. 13 shows one of the lid plates as viewed from the back. In the figure, the cover plate 22 formed in a substantially plate shape is divided into a base portion 22b and a front portion 22a at a substantially central portion in the depth direction, and the base portion 22b and the front portion 22a are connected to a central connecting portion 22c and a width. It is connected by connecting portions 22e and 22e at both ends in the direction. The base portion 22b is connected to the lid main body portion 24 at the front side portion, and a pair of thin plate portions 22b1 and 22b1 are formed on both outer sides in the width direction. Also, a thin plate portion 22a1 having a substantially U-shape when viewed from above is formed on both the outer side and the rear side in the width direction of the front portion 22a. The connecting portions 22e and 22e connect the thin plate portions 22b1 and 22b1 and the thin plate portion 22a1 and have the same thickness as these. A rectangular frame-shaped reinforcing rib 22b2 is formed on the inner side of the thin plate portions 22b1 and 22b1 in the base portion 22b to increase the plate thickness. Similarly, a rectangular frame-shaped reinforcing rib 22a2 is formed on the inner side of the thin plate portion 22a1 in the tip portion 22a with a thick plate thickness. A portion surrounded by the reinforcing rib 22b2 and the reinforcing rib 22a2 is formed in a flat plate shape.

  A pair of temporary fixing portions 22d and 22d are extended downward inside each of the pair of thin plate portions 22b1 and 22b1 in the base portion 22b, and further extended further to the far end of the temporary fixing portions 22d and 22d. It has substantially reached part 22a. A substantially plate-shaped closing plate 22a3 is suspended below a portion of the tip portion 22a that joins the connecting portion 22c. Both ends in the width direction of the closing plate 22a3 are formed so as to be inside the outer edges in the width direction of the temporary fixing portions 22d and 22d. The closing plate 22a3 is supported from the front side by a triangular plate-like connecting portion 22c, and an engaging portion 23 is erected perpendicularly to the closing plate 22a3 substantially at the center of the rear surface.

The engaging portion 23 is composed of a substantially plate-like engaging plate 23a and an engaging tip portion 23b having a wide tip, and the height is slightly smaller than the height h of the window portion 40d. . The engagement tip portion 23b is formed with a first engagement guide surface 23b1 that is inclined so that the thickness decreases toward the tip, and the front side end portion having the largest thickness in the engagement tip portion 23b is the window portion 40d. An engagement surface 23b2 that is orthogonal to the engagement plate 23a and faces the closing plate 22a3 is formed at the front end of the engagement destination portion 23b. A second engagement guide surface 23b3 is formed at the lower end of the engagement destination portion 23b.

  The second engagement guide surface 23b3 is formed so that the normal direction is opposite to the first engagement guide surface 23b1 and obliquely behind. The restriction insertion portion 23c is formed by cutting out the front side of the engagement destination portion 23b at the lower end of the engagement plate 23a. The restriction insertion portion 23c has a substantially triangular shape when viewed from the side, and the inner projecting portion of the restriction destination portion 42b of the retaining piece 40 can be just fitted. The wall surface of the restriction insertion portion 23c substantially parallel to the closing plate 22a3 is referred to as a restriction insertion surface 23c1. On the other hand, a section screen 24 d in which a rail insertion portion 24 c is formed on the side of the lid plate 22 extends downward at the boundary between the lid body portion 24 and the lid plate 22.

  FIG. 14 shows the state of the cover plate 22 and the box portion 12 when the control box 70 is closed as shown in FIG. 3 as viewed from above. In the figure, the lid member 20 is slid backward until the rail insertion portion 24c of the lid member 20 fits into the guide rail 14c of the dish member 10. At the same time, the section screen 24d is configured to close the notch 14c1 that opens the box portion 12 toward the dish body 14 from the dish body 14 side. Therefore, the receiving space for the control board 25 that is completely closed from the outside can be formed by the dish body 14 and the lid body 24.

  When the lid plate 22 slides together with the lid member 20, the rear end portion of the lid plate 22 reaches the rear wall surface 12 b of the box portion 12 and closes the upper opening of the box portion 12. That is, the inside of the box portion 12 is a space closed from the outside except for the opening on the side of the connecting portion 22 c in the cover plate 22. Thin plate portions 22 a 1, 22 b 1, 22 b 1 constituting the outer edge and the outer edge of the cover plate 22 are inserted into guide portions 12 b 1 having a substantially U-shaped cross section formed at the upper ends of the side surfaces 12 b of the box portion 12. Yes. Thereby, since the shape of the contact part of the cover plate 22 and the box part 12 becomes complicated, it is difficult to allow foreign matter to enter the inside of the box part 12 through the gap between the cover plate 22 and the box part 12. .

  Further, since the guide portion 12b1 guides the slide with the box portion 12 sandwiched in the width direction and up and down when the cover plate 22 slides with respect to the box portion 12, the cover plate 22 can be smoothly slid. . In the state shown in the figure, the engagement plate 23 a, the engagement destination portion 23 b and the closing plate 22 a 3 formed below the lid plate 22 are accommodated inside the box portion 12. That is, they are isolated from the outside. However, when the lid plate 22 slides with respect to the box portion 12, the box portion 12 communicates with the dish main body portion 14 by the notch 14 c 1, so that the engagement plate 23 a formed below the lid plate 22 or The engaging portion 23b and the closing plate 22a3 can enter the inside of the box portion 12.

  FIG. 15 shows the inside of the box 12 in the state of FIG. 14 as seen from the Z1 cross section of FIG. In the figure, the retaining piece 40 is in the second mounted state. The engagement plate 23a and the engagement destination portion 23b advance toward the inner side of the box portion 12 together with the sliding of the lid plate 22. When proceeding a predetermined amount in the back, it becomes a position overlapping with the frame portion 40c oriented in the front side in the second wearing state, but through the window portion 40d formed inside the frame portion 40c, further to the back Can proceed.

  That is, the height and width of the engagement destination portion 23b are formed smaller than the height h and width r of the window portion 40d, and the engagement plate 23a and the engagement destination portion 23b have the same height as the window portion 40d. Thus, the engagement destination portion 23b can be inserted through the window portion 40d. Thereby, in the 2nd mounting state, the control box 70 can be closed, without the interference | blocking piece 40 and the engagement point part 23b interfering at all. Of course, when the lid plate 22 is slid to the near side, the retaining piece 40 and the engagement destination portion 23b do not interfere with each other. On the other hand, the temporary fixing portions 22d and 22d also advance toward the back while sliding on the cover plate 22 and in sliding contact with the side wall surfaces 12b and 12b of the box portion 12, respectively.

  FIG. 16 shows the inside of the box 12 in the state of FIG. 14 as seen from the Z1 cross section of FIG. In the figure, the retaining piece 40 is in the first mounted state. The protective member 50 is also mounted inside the box portion 12. In the first mounting state, the engagement destination portion 23b advances toward the back inside the box portion 12 together with the slide of the cover plate 22, and when it advances to the back by a predetermined amount, the stop tip portion 41b of the stop piece 40 and the restriction portion. Each abuts against the tip 42b. Then, when further advanced to the back, as shown by the solid line, the engagement tip portion 23b and the retaining tip portion 41b are engaged. That is, the engagement surface 23b2 that faces the front side in the engagement destination portion 23b and the retaining surface 41b2 that faces the rear side in the withdrawal destination portion 41b face each other, and the engagement surface 23b2 moves to the front side. No longer allowed.

  Thereby, the lid plate 22 cannot slide to the near side with respect to the box portion 12 and the lid member 20 cannot slide to the near side with respect to the dish member 10. Further, at this time, since the rail insertion portion 24c of the lid member 20 is fitted and abutted against the guide rail 14c of the dish member 10, it is impossible to slide the lid member 20 further back. Furthermore, since the lid member 20 and the dish member 10 cannot be moved relative to each other other than sliding in the depth direction, the lid member 20 cannot be completely moved relative to the dish member 10. That is, the accommodation space of the control board 25 closed as described above can be completely sealed.

  On the other hand, the temporary fixing portions 22d and 22d that move toward the back while sliding on the side wall surfaces 12b and 12b of the box portion 12 together with the sliding of the cover plate 22 include an engagement destination portion 23b and a removal destination portion 41b. When engaged, they come into contact with the front side end portions of the side plates 50a, 50a of the protection member 50. Thereby, the protection member 50 can be prevented from coming off to the near side. Both ends of the closing plate 22a3 in the width direction substantially contact the side plates 50a and 50a of the protection member 50 from the inside, respectively, and the lower end of the closing plate 22a3 substantially contacts the bottom plate 50b of the protection member 50. Thereby, when the engagement point part 23b and the retaining point part 41b engage, the back space of the box part 12 located under the front part 22a can be closed from the outside.

  FIG. 17 shows a state where the engaging portion 23 and the retaining portion 41 are engaged. In the same figure, the portions other than the retaining piece 40 and the engaging portion 23 are not shown for explanation. Since the engaging part 23 is inserted at the same height as the window part 40d as described above and the length in the height direction is substantially the same height h as the retaining part 41, the retaining part 41 and the restricting part 42 It is a relationship that interferes with both. The engagement destination portion 23b advances to the near side, and the first engagement guide surface 23b1 contacts the retaining guide surface 41b1 of the retaining tip portion 41b. Since the first engagement guide surface 23b1 and the retaining guide surface 41b1 are inclined with respect to the advancing direction of the engagement destination portion 23b, both try to push each other outward in the width direction while sliding. Accordingly, the retaining plate 41a tries to bend outward, but the holding column 12f is in contact with the outside, so that the original shape is maintained. On the other hand, the engagement plate 23a is bent so that the engagement destination portion 23b is separated from the retaining portion 41b because the engagement destination portion 23b is a free end.

  On the other hand, the second engagement guide surface 23b3 also comes into contact with the inner protruding portion of the restriction destination portion 42b of the restriction portion 42 as the engagement destination portion 23b advances. Since the regulation guide surface 42b1 and the second engagement guide surface 23b3 of the regulation destination portion 42b are also inclined with respect to the advancing direction of the engagement destination portion 23b, both try to push each other outward while sliding. However, since the engaging portion 23b tends to be displaced away from the retaining portion 41b as described above, the restricting portion 42b is pushed downward or outward in the width direction. However, since the substantially rod-shaped restricting rod 42a is supported by the holding column 12d from the outside in the width direction, the restricting rod 42a is bent so as to displace the restricting tip portion 42b downward.

  As described above, when the engagement plate 23a and the regulation rod 42a are bent in the respective directions, the engagement destination portion 23b can be further advanced. In addition, when the engagement plate 23a and the regulating rod 42a are bent and the engagement destination portion 23b advances to the back, a considerable reaction force is exerted on the engagement portion 23. However, the connecting portion is connected to the back surface of the closing plate 22a3. Since 22c is supporting in the opposite direction of the same reaction force, it is possible to push in the engaging part 23 reliably. That is, the connecting portion 22c can function as a reinforcing rib for the closing plate 22a3.

  Then, as shown in FIG. 18, when the engagement destination portion 23b passes by the side of the removal stop portion 41b, the interference between the first engagement guide surface 23b1 and the removal guide surface 41b1 is eliminated, and the engagement plate 23a is The original shape can be restored. Then, the engagement surface 23b2 that faces the front side in the engagement destination portion 23b and the retaining surface 41b2 that faces the rear side in the retaining portion 41b face each other, and the engagement surface 23b2 moves to the front side. No longer allowed. In addition, since the retaining piece 40 is inserted through the holding column 12c and attached, the engagement surface 23b2 does not move forward with the retaining piece 40.

  At this time, the restriction insertion portion 23c of the engagement plate 23a reaches a position where the restriction destination portion 42b waits. Therefore, the restriction rod 42a returns to the current shape, and the inner protrusion of the restriction tip portion 42b can enter the restriction insertion portion 23c. As a result, the restriction insertion surface 23c1 that faces the front side in the restriction insertion portion 23c and the second restriction surface 42b2 that faces the back in the inner projecting portion of the restriction destination portion 42b face each other, and the restriction insertion surface 23c1 is formed. Moving to the near side is not allowed. That is, it is possible to prevent the engaging portion 23 from moving to the near side at the two locations of the engaging surface 23b2 and the restriction insertion surface 23c1. That is, the engaging portion 23 is engaged with the retaining piece 40 at two locations.

  Further, once the engagement is completed as described above, the inner first restriction surface 42a1 of the restriction rod 42a that has returned to the original shape comes into contact with the engagement plate 23a from the outside in the width direction. Therefore, in order to bend the engagement plate 23a so that the engagement destination portion 23b is separated from the prevention destination portion 41b in order to release the engagement between the engagement destination portion 23b and the prevention destination portion 41b, the restriction rod 42a is also simultaneously used. Must be bent outward. However, since the regulating rod 42a is in contact with the holding column 12d from the outside, it cannot be bent outward. Even if the engaging plate 23a and the restricting rod 42a are bent outward at the same time, the engagement between the restricting tip portion 42b and the restricting insertion portion 23c is maintained, so that the engagement cannot be released. If the engagement is to be released, the engaging plate 23a must be bent outward while the regulating rod 42a is bent downward. Therefore, it is very difficult to release the engagement without destroying the engaging portion 23, the retaining portion 41, and the restricting portion 42.

  Furthermore, as described above, the space in which the engaging portion 23, the retaining portion 41, and the restricting portion 42 that contribute to the engagement are accommodated from the outside by the lid plate 22, the bottom surface 12a of the box portion 12, each wall surface 12b, and the closing plate 22a3. Since it is closed, the engagement cannot be released from the outside by acting on the engagement destination portion 23b and the removal destination portion 41b. In addition, the space in which the engaging portion 23, the retaining portion 41, and the regulating portion 42 that contribute to the engagement are accommodated is protected from below and from the side by the metal protection member 50. Even if a hole is formed in the bottom surface 12a or the like, the foreign matter cannot reach the engaging portion 23, the retaining portion 41, and the regulating portion 42, and can be broken to release the engagement.

Further, by reversing the retaining piece 40 inside the box portion 12, it is possible to select whether or not the box portion is engaged. Therefore, it is not necessary to insert a pin or the like from the outside when selecting the engagement. That is, since it is not necessary to form a through hole for inserting a pin or the like from the outside in the box part or the cover plate, the closing property inside the box part can be improved.

  In particular, in this embodiment, the protection member 50 is only inserted and mounted in the gap of the box portion 12 and is not firmly fixed. That is, the protection member 50 leaves room for deformation inside the box portion 12. Accordingly, as shown in FIG. 19, when a hole is drilled in the wall surface 12b or the bottom surface 12a of the box portion 12 with a drill or the like, and the protective member 50 is to be penetrated, the upper ends of the side plates 50a and 50a are bent inward. The propulsion direction of the drill can be deflected upward. Further, the propulsion direction of the drill can be diverted upward, and the side plates 50a, 50a can vibrate to dissipate the propulsion force of the drill.

  Therefore, it is very difficult to make a hole with a drill or the like at the exact position of the side plates 50a, 50a. Similarly, since the bottom plate 50b can be bent so as to displace the center portion upward, the driving force of the drill can be dissipated in the same manner. Thereby, even if a hole or the like is drilled in each wall surface 12b or bottom surface 12a of the box portion 12, the foreign matter reaches the engagement destination portion 23b or the removal destination portion 41b, and breaks them to release the engagement. I can't do that. Further, since the thin plate portion 22a1 of the lid plate 22 enters the guide portion 12b1 having a substantially U-shaped cross section, it is difficult for foreign matter to enter from the gap between the lid plate 22 and the box portion 12.

  Further, since the thin plate portion 22a1 of the cover plate 22 enters the guide portion 12b1 having a substantially U-shaped cross section, the cover plate 22 cannot be peeled upward. However, since the cover plate 22 is exposed at the upper side (the back side of the pachinko machine) that is easily visible, even if a fraud is made by making a hole in the cover plate 22 or peeling it upward, the fraud The traces of can be easily confirmed. Moreover, by not protecting the inner side of the cover plate 22 with the protective member 50, the engagement state of the engaging portion 23, the retaining portion 41, and the restricting portion 42 can also be visually recognized through the transparent synthetic resin cover plate 22. Can make it easier to detect fraud. Furthermore, since the retaining piece 40 is colored red, it is easy to check the destruction state from the outside. However, the retaining piece 40 only needs to be colored in a conspicuous color, and is not limited to red.

  As described above, it is difficult to open the control box 70. However, in maintenance of the control board 25, the control box 70 must be opened by sliding the plate member 10 and the lid member 20. In that case, as shown in FIG. 20, the connecting portion 22c is broken by a nipper or the like, and the connecting portions 22e and 22e at both ends in the width direction are also broken together with the guide portion 12b1, so that the cover plate 22 is made to have the front portion 22a and the base portion 22b. Can be separated. That is, since the engaging portion 23 that contributes to the engagement extends from the front portion 22a, if the base portion 22b is separated from the front portion 22a, the restraining force due to the engagement does not reach the base portion 22b or the lid member 20. . Therefore, the lid member 20 can be slid with respect to the dish member 10, and can be in an opened state as shown in FIG. Of course, those who perform fraud can also be opened in the same way, but as described above, the connecting portions 22c, 22e, and 22e are exposed to the upper side (the back side of the pachinko machine) that is easy to visually recognize. Can be easily discovered. Therefore, it is possible to determine whether the trace is illegal or appropriate by referring to a regular opening history by maintenance or the like.

  Further, when the base portion 22b is separated from the front portion 22a and the lid member 20 is slid to the front side, the temporary fixing portions 22d and 22d extending from the base portion 22b are also slid to the front side. Therefore, the retaining of the protective member 50 toward the front side is naturally released. In other words, the protective member 50 can be easily removed from the box portion 12 that does not need to be protected from the outside by breaking the connecting portion 22c to release the sealing. Thus, by removing the protective member 50 after use, only the synthetic resin tip 22a and the retaining piece 40 remain on the used dish member 10. That is, since a different kind of material such as a metal material does not remain on the dish member 10, recycling can be easily performed without intentionally releasing the retaining piece 40 and removing the retaining piece 40. Also, the protective member 50 can be reused by being mounted on another box portion 12.

  By rupturing the connecting portion 22c of the cover plate 22, the cover plate 22 cannot be used for sealing thereafter. However, since five sets of the cover plate 22 and the box portion 12 are provided, it is possible to perform sealing next time with the cover plate 22 and the box portion 12 in which the connecting portion 22c is not broken. That is, the sealing can be performed up to five times. In sealing with the cover plate 22 and the box part 12 that do not break the connecting part 22c, the retaining piece 40 is set to the first mounting state in the box part 12 to be sealed when opened. Just keep it. Thereby, the engagement destination part 23b and the securing destination part 41b can be engaged in the box part 12 which is going to seal. Moreover, since the protective member 50 can be removed from the box portion 12 used for the previous sealing as described above and attached to the box portion 12 to be sealed, the protective members 50 are prepared in the same number as the number of the box portions 12. There is no need to keep it. Accordingly, the component cost can be reduced.

  On the other hand, in order to seal the control box 70, it is sufficient that the pair of cover plates 22 and the box portion 12 are engaged with each other. You just have to wear it as a wearing state. In switching between the first mounting state and the second mounting state, it is only necessary to invert and attach the retaining piece 40, so that the work is not complicated. Further, even if the retaining piece 40 that is not used is mounted in the second mounting state, it can be mounted in the mounting space of the retaining piece 40 that is originally used for engagement, so that it is not used for engagement. There is no need to secure a separate space for mounting the piece 40. Therefore, the control box 70 can be formed compactly. Further, even the retaining piece 40 in the second mounted state is accommodated in the closed space inside the box portion 12 when the control box 70 is sealed. Therefore, it is possible to prevent the unused retaining piece 40 from being destroyed or removed and lost.

(4) Regarding the second embodiment:
FIG. 21 shows the control box attached to the gaming machine according to the second embodiment as seen from the width direction. In the same figure, the lid member 120 and the dish member 110 constituting the control box 170 are connected by a rotary hinge 150, and rotate around the side where the lid plate 122 and the box portion 112 are formed as free ends. Is possible. The cover plate 122 extends in the tangential direction of the rotation track of the cover plate 122 from the tip of a substantially plate-shaped sealing plate 127 that extends the cover member 120 in the centrifugal direction of rotation. The box part 112 is formed on the track of the cover plate 122 and waits for the cover plate 122 that travels on the track. An engaging portion 123 similar to that of the previous embodiment is formed on the cover plate 122 so that the tip is directed to the box portion 112.

  FIG. 22 shows the lid plate 122 as viewed from the side. The lid plate 122 is also formed in the same manner as in the previous embodiment. A plate-shaped protective wall 122a4 that is substantially parallel to the lid plate 122 is directed from the end farthest from the lid plate 122 of the closing plate 122a3 toward the box portion 112. It is formed as follows. On the other hand, in FIG. 21, the box part 112 is also provided with the same retaining piece 140 as in the previous embodiment, and the distal end of the retaining part 141 of the retaining part 140 is oriented to the cover plate 122. The shape of the retaining piece 140 is the same as that of the first embodiment, but is formed of a metal material. Moreover, the box part 112 is formed in the substantially box shape, and has opened upward and the back. In the present embodiment, five cover plates 122 and five box portions 112 are formed in parallel in the width direction. However, in this embodiment, the cover plate 122, the box portion 112, and the sealing plate 127 are colored from the inside with a black paint.

Even in this case, the control box 170 can be reliably sealed. The inner and upper openings of the box portion 112 are closed by the lid plate 122 and the sealing plate 127, respectively, and the space in which the engaging portion 123 and the retaining portion 141 are accommodated is closed by the closing plate 123a3. The inside of the box part 112 can be closed from the outside. Further, when the engaging portion 123 and the retaining portion 141 are engaged, the protective wall 123a4 substantially contacts the bottom surface of the box portion 112 in parallel from the inside. That is, the protective wall 123a4 can protect the closed space in which the engaging portion 123 and the retaining portion 141 are accommodated from the inside.

  Therefore, it is possible to prevent the engagement between the engagement portion 123 and the retaining portion 141 that are engaged inside the box portion 112 from being easily released. Moreover, since the cover plate 122, the box portion 112, and the sealing plate 127 are colored from the inside with a black paint, it is impossible to visually recognize the inside of the box portion 112 from the outside. Therefore, it cannot be visually recognized from the outside which box portion 112 of the five box portions 112 is engaged. That is, since it is possible to make it impossible for the person who performs the fraud to know which box portion 112 can be destroyed, the fraud can be prevented. Even if the retaining piece 140 to be destroyed is specified, the retaining piece 140 is formed of metal and cannot be easily broken to release the seal.

(5) Regarding the third embodiment:
FIG. 23 shows the box portion according to the third embodiment as viewed from above. In the same figure, holding columns 212c to 212f are erected inside the box portion 212, and a retaining piece 240 is inserted into a gap formed by the holding columns 212c to 212f. The retaining piece 240 is formed in a substantially plate shape, has a retaining portion 241b at one end, and has a substantially plate-like fixing portion 240c at the other end. The fixing portion 240c is orthogonal to the retaining plate 41a in the retaining piece 240, and has a width w longer than the thickness of the retaining plate 241a. The retaining plate 41a is slightly thinner than the holding column 212c and the holding column 212e, and the interval s between the holding column 212c and the holding column 212f. The thickness of the fixing portion 240c is smaller than the distance u between the holding column 212c and the inner wall surface 12b of the box portion 212.

  By doing in this way, the retaining piece 240 inserted in the gap formed by the holding columns 212c to 212f can be fixed so as not to move to the near side. Accordingly, when the engaging portion 223 is engaged as shown by a solid line in FIG. 9, the engaging portion 223 can be restrained from moving to the near side. That is, also in this embodiment, the control box can be sealed as in the above-described embodiment.

  FIG. 24 shows the lid plate according to the third embodiment as viewed from the side. In the figure, a pair of preliminary mounting portions 245a and 245b having a substantially L shape in side view are formed below the base portion 222b of the lid plate 222. Each of the preliminary locking portions 245a and 245b has a plate-like portion perpendicular to the lid plate 222, and the interval between them is formed larger than the width w of the fixing portion 240c of the retaining piece 240. Further, each of the preliminary mounting portions 245a and 245b has a plate-like portion parallel to the lid plate 222, and the gap formed by the tips facing each other is formed to be the same as the gap s. The distance between the plate-like portion parallel to the cover plate 222 and the cover plate 222 is formed to be the same as the distance u. The retaining piece 240 can be attached to the lid plate 222 by inserting the fixing portion 240c of the retaining piece 240 from the side into the gap formed by the preliminary attachment portions 245a and 245b.

  By doing so, it is possible to store a preliminary retaining piece 240 that is not used for engagement inside the box portion 212. Since the inside of the box portion 212 is closed from the outside when the control box is sealed, the spare retaining piece 240 is not removed from the outside. Therefore, it is possible to prevent the spare retaining piece 240 from being lost. On the other hand, when the control box is opened, the box portion 212 can be opened, so that the retaining piece 240 to be used next time can be easily detached from the preliminary mounting portions 245a and 245b.

  Furthermore, as shown in FIG. 25, the preliminary mounting portions 245a and 245b can be formed on the lid main body portion 224. Even in this case, since the preliminary retaining pieces 240 can be stored in a space closed from the outside when the control box is sealed, the retaining pieces 240 can be prevented from being lost. Of course, the preliminary mounting portions 245a and 245b may be formed inside the control box, or may be formed in the dish body portion. Since other configurations are the same as those in the first embodiment, description thereof is omitted.

(6) About the fourth embodiment:
FIG. 26 shows the box portion according to the fourth embodiment as viewed from above. In the same figure, holding pillars 312c to 312f are erected in the box 312 as in the previous embodiment, and a retaining piece 240 is inserted into a gap formed by the holding pillars 212c to 212f. Further, the shape of the retaining piece 240 is the same as that of the previous embodiment. However, a cutout 312c1 having the same width as the interval s is formed in the holding column 212c. As indicated by broken lines, the holding column 312c can hold the retaining piece 340 by sandwiching the retaining plate 341a in the thickness direction by the notch 312c1. Naturally, the retaining piece 340 indicated by a broken line does not engage with the engaging portion 323.

  In other words, it is also possible to store a preliminary retaining piece 340 that is not used for engagement in a space behind the closing plate 322a3 in the box 312. By doing so, the spare retaining piece 340 can be accommodated in a more closed space in the box 312, so that the spare retaining piece 340 can be more reliably prevented from being lost. Can do.

(7) Summary:
As described above, in the gaming machine according to the present invention, by engaging the engaging portion 23 and the retaining piece 40 in the closed space formed by the box portion 12 and the cover plate 22 at the time of sealing, Therefore, it is impossible to destroy the engaging portion 23 and the retaining piece 40. Further, since no pins or the like are inserted from the outside, there is no gap. Therefore, the engaging part 23 and the retaining piece 40 can be engaged in a more closed space. It is also possible to select whether or not to engage by changing the mounting state of the retaining piece 40.
