JP 2003-209322 A (unpublished application)

In the gaming machine described above, since the fraud cannot be prevented if the metal piece is easily removed, the metal piece is locked at the pin receiving portion. Thereby, although fraud prevention can be realized, conversely, it has been difficult to remove the metal piece from the plate member of the control box that has been used. Therefore, there is a problem that the synthetic resin dish member and the metal piece cannot be separately collected and the recyclability is poor.
The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a gaming machine including a control box that is reliably protected by a protective member and has good recyclability.

In order to achieve the above object, the invention according to claim 1 is controlled by a control box in which the opening of the plate member is closed by the cover member by relatively moving the plate member and the cover member to a predetermined position.

Can be closed. Then, the control board is sealed in the closed accommodation space. The lid plate includes a base portion extending from one of the dish member and the lid member, and a tip portion connected to the base portion via a breakable connecting portion. On the other hand, a substantially box-shaped box portion is extended from one of the plate member and the cover member on which the cover plate is not provided. The box portion is closed from the outside by the lid plate when the opening of the dish member is closed. The retaining portion is provided inside the box portion, and engages with the engaging portion inside the box portion when the opening of the dish member is closed. A metal protection member is provided inside the box portion and protects the inner wall surface of the box portion from the inside. The temporary fixing part is formed by extending the base part, and the temporary fixing part comes into contact with the protective member when the opening of the dish member is closed.

  That is, by protecting the inside of the box portion with the protective member, the engaging portion and the retaining portion contributing to the engagement for sealing the control box can be protected from the outside. Therefore, it is possible to prevent the control box from being unsealed by breaking the engaging portion and the retaining portion from the outside. Since the said protection member is metal, the inside of the said box part can be protected firmly. Further, when the box part is closed by the cover plate, the temporary fixing part comes into contact with the protective member. That is, when the control box is sealed, the protection member is fixed, and the engagement portion and the retaining portion can be reliably protected from the outside.

  On the other hand, the sealing of the control box can be released by breaking the connecting portion.

That is, the retaining portion can be moved together with the base portion. Therefore, by moving the temporary fixing part, the contact of the temporary fixing part with the protective member can be released. When the contact of the temporary fixing portion with the protective member is released, the protective member can be moved in the direction in which the temporary fixing portion is in contact. That is, by releasing the sealing of the control box, it is possible to release the restraint of the temporary fixing portion with respect to the protective member. Therefore, even if the box part and the protection member are formed of different materials, they can be easily separated and recovered and the recyclability is improved. That is, when the control box is sealed, the protection by the protection member is ensured, and when the control box is opened, the protection member can be easily attached and detached.

In addition, in this invention, the said protection member is not restricted to what is fixed in the said box part. When the protective member is not fixed to the box portion, the protective member is released from the restraint of the temporary fixing portion, so that the protective member is not restricted to the box portion. It can be easily removed from the part. On the other hand, when fixing the said protection member to the said box part, the fixation with respect to the same box part of the said protection member can be made stronger by the said temporary fixing part contact | abutting with respect to the same protection member.

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 this 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 other words, the retaining piece 12c is inserted into the retaining piece 40c so that the holding column 12c is slightly wider than the width r of the holding column 12c, and the length p in the sliding direction is longer than the length f of the holding column 12c. Since the insertion hole is formed, the holding column 12c can be inserted through the insertion hole. Note that the insertion direction of the retaining piece 40 with respect to the holding column 12c coincides with the axial direction of the holding column 12c erected vertically from the bottom surface 12a, and thus the insertion direction and the sliding direction are perpendicular. 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.

  Therefore, even if the retaining piece 40 is reversed and inserted into the holding column 12c, the retaining column 12c and the retaining piece 40 do not interfere with each other. 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. That is, the protective member 50 is sandwiched and held in the thickness direction between the holding columns 12d to 12f and the side wall surfaces 12b and 12b, but the gap is formed larger than the thickness, A play is formed in the thickness direction.

  Moreover, since the predetermined notch 50c is formed in the bottom face plate 50b, the bottom face plate 50b and each holding pillar 12c-12f do not interfere. 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 protective member 50 is mounted, the protective member 50 is not particularly fixed by engagement, adhesion, or the like, so that the protective 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. A first 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. A wall surface of the restriction insertion portion 23c substantially parallel to the closing plate 22a3 is referred to as a second engagement 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 first 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 tip portion 41b face each other, and the first engagement surface 23b2 faces the near side. It will not be allowed to move to the side.

  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, respectively. Thereby, the protection member 50 can be fixed to the near side to prevent it from coming off. 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 back, and the first engagement guide surface 23b1 contacts the retaining guide surface 41b1 of the retaining 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. At this time, since the retaining portion 41b is formed at the free end of the engaging portion 23 formed in a beam shape, the displacement amount of the retaining portion 41b can be increased.

  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 regulating rod 42a is supported by the holding column 12d from the outside in the width direction, the regulating rod 42a is bent so as to displace the regulating tip portion 42b downward. Further, since the regulating rod 42a is sandwiched between the holding column 12d and the holding column 12c which are parallel to each other, it is guided to bend in the vertical direction. Therefore, the regulation rod 42a can be bent stably in the vertical direction. In addition, since the engaging part 23 is formed in plate shape, it cannot bend except in the normal line direction of the engaging part 23. Therefore, the engaging portion 23 does not bend upward due to interference with the restricting portion 42. Further, since the restriction destination portion 42b is formed at the free end of the restriction portion 42 formed in a beam shape, the displacement amount of the restriction destination portion 42b can be increased.

  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 first engagement surface 23b2 that faces the front side in the engagement destination portion 23b and the retaining surface 41b2 that faces the back side in the retaining tip portion 41b face each other, and the first engagement surface 23b2 faces the near side. It will not be allowed to move to the side. That is, when the engagement portion 23 moves, the first engagement surface 23b2 and the retaining surface 41b2 can move without interference by bending of the engagement portion 23, and when the movement is completed, the engagement portion 23 is bent. The joining portion 23 returns to the original shape, and the first engagement surface 23b2 and the retaining surface 41b2 can face each other. Since the first engagement surface 23b2 is formed at the free end having a large displacement when the engagement portion 23 is bent in the engagement portion 23, the first engagement surface 23b2 can be moved away from the retaining surface 41b2.

  In addition, since the retaining piece 40 is inserted through the holding column 12c and attached, the first engagement surface 23b2 does not move to the near side with the retaining piece 40. Since the direction in which the first engagement surface 23b2 moves and the insertion direction in which the holding column 12c is inserted into the retaining piece 40 are perpendicular to each other, the retaining piece 40 is retained even when the first engaging surface 23b2 is moved. There is no escape from the pillar 12c. Therefore, the retaining piece 40 does not come off from the holding column 12c, and the restraining force of the retaining column 12c on the retaining piece 40 is not lost.

  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 second engagement surface 23c1 facing the front side in the restriction insertion portion 23c and the second restriction surface 42b2 facing the back in the inner projecting portion of the restriction tip portion 42b face each other, and the second The engaging surface 23c1 is not allowed to move forward.

  That is, when the engaging portion 23 moves, the restricting portion 42 bends so that the second engaging surface 23c1 and the second restricting surface 42b2 can move without interference, and the movement is completed. Then, the restricting portion 42 returns to the original shape, and the second engaging surface 23c1 and the second restricting surface 42b2 can face each other. Since the second restricting surface 42b2 is formed at the free end having a large displacement when the restricting portion 42 is bent in the restricting portion 42, the second restricting surface 42b2 does not interfere with the second restricting surface 42b2. Can be moved to the back. By doing in this way, it can become impossible to move the engaging part 23 to the near side by interference of two places with the 1st engaging surface 23b2 and the 2nd engaging 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. Further, since the engaging portion 23 is formed in a plate shape and cannot be bent except in the normal direction of the engaging portion 23, the engagement portion 23 can only be bent outward to release the engagement. Absent. Therefore, it is possible to prevent the engagement from being reliably released by the restricting portion 42 that abuts the engaging portion 23 on the outside.

  If the engagement is to be released, the engaging plate 23a must be bent outward while the regulating rod 42a is bent downward. That is, since the bending direction of the engaging portion 23 at the time of engagement and the restricting portion 42 are different directions, the engagement cannot be released unless an external force is applied in two directions. Furthermore, since the bending direction of the engaging part 23 and the restricting part 42 is an orthogonal direction, the component for deflecting the restricting part 42 to the external force for deflecting the engaging part 23 in the direction of releasing the engagement is Can be excluded. Similarly, the component for deflecting the engaging portion 23 can be prevented from being included in the external force for deflecting the regulation rod 42a in the direction of releasing the regulation.

  Therefore, in order to release the seal, an external force in two directions must be applied, and the release of the engagement can be made more difficult. Furthermore, even if the engagement plate 23a and the restriction rod 42a are bent outward at the same time, the engagement between the restriction destination portion 42b and the restriction insertion portion 23c is maintained, so that the engagement cannot be released. Therefore, it is very difficult to release the engagement without destroying the engaging portion 23, the retaining portion 41, and the restricting portion 42.

  The engaging portion 23b and the retaining portion 41b that cause the engaging portion 23 to bend by bringing the engaging portion 23 and the retaining portion 41 into contact with each other at an inclined surface correspond to the engaging guide portion according to the present invention. Further, the restriction destination portion 42b and the second engagement guide surface 23b3 for bending the restriction portion 42 by bringing the engagement portion 23 and the restriction portion 42 into contact with each other on the inclined surface correspond to the restriction guide portion referred to in the present invention. Further, the engagement guide portion of the present embodiment bends only the engagement portion 23 in the width direction, and the restriction guide portion bends only the restriction portion 42 downward. Therefore, since two types of bending required for engagement can be distributed to the engaging portion 23 and the restricting portion 42, it is possible to prevent the load and deformation from being concentrated on the engaging portion 23.

  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, and thus each wall surface 12 b of the box portion 12. 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.

  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 protective member 50 is sandwiched and held in the thickness direction between the holding columns 12d to 12f and the side wall surfaces 12b and 12b, but the gap is formed larger than the thickness, A play is formed in the thickness direction. 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. Further, the temporary fixing portions 22d and 22d that come into contact with the protective member 50 from the front side to prevent the protective member 50 from being fixed come into contact with the protective member 50 from a direction perpendicular to the thickness direction in which the protective member 50 swings. Therefore, the temporary fixing portions 22d and 22d do not prevent the side plates 50a and 50a from swinging.

  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.

  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.

  In particular, since the connecting portions 22e and 22e at both ends in the width direction are tightly covered from the upper side and the outer side by guide portions 12b1 formed in the box portion 12, only the connecting portions 22e and 22e are changed to be engaged. Unauthorized attempts to cancel can be prevented. Furthermore, in order to break the connecting portions 22e and 22e, it is necessary to break the guide portion 12b1 together, so that the breaking scale becomes large. Therefore, the opening history of the control box 70 can be visually recognized more clearly. Further, even if only the connecting portions 22e and 22e are broken without the guide portion 12b1 being broken, the guides can be easily grasped so that the breaking state of the connecting portions 22e and 22e can be easily grasped. The portion 12b1 may be formed to be transparent, and the connecting portions 22e and 22e may be colored in a conspicuous color. The guide portion 12b1 corresponds to the connection cover in the present invention.

  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. That is, 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 portions 22c, 22e, and 22e 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 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, the retaining piece 40 is accommodated in the closed space inside the box portion 12 when the control box 70 is sealed even in the second mounting state. Therefore, it is possible to prevent the unused retaining piece 40 from being destroyed or removed and lost.

(4) Modification:
FIG. 21 shows the protective member according to the second embodiment as viewed from an oblique direction. In the figure, the protection member 150 includes a bottom plate 150b and side plates 150a and 150a, and the side plates 150a and 150a are bent to form a pair of locking surfaces 150a1 and 150a1. The locking surfaces 150a1 and 150a1 are flat surfaces parallel to each other, and are opposed to the inner side in the width direction than the side plates 150a and 150a. Locking holes 150a2 and 150a2 are formed in the central portions of the locking surfaces 150a1 and 150a1, respectively.

  FIG. 22 shows a state where the engaging portion enters the box portion. In the figure, a protective member 150 is mounted inside the box portion 112, and the engaging portion 123 is moved toward the back in a state where the protective member 150 is mounted. At this time, the temporary fixing portions 122d and 122d extending from the engaging portion 123 also advance toward the back. Locking claws 122d1 and 122d1 extend from the temporary fixing portions 122d and 122d to the back, respectively, and the locking claws 122d1 and 122d1 also move to the back together with the engaging portion 123. The locking claws 122d1 and 122d1 are in sliding contact with the inner side of the side wall surface 112b of the box portion 112, and a protrusion protruding inward is formed at the rear end portion.

  Then, when the engaging portion 123 is moved until the engaging portion 123 and the retaining portion 141 are engaged, the protrusions at the distal ends of the engaging claws 122d1 and 122d1 enter the engaging holes 150a2 and 150a2 in the protective member 150, respectively. It is possible. Until the leading ends of the locking claws 122d1 and 122d1 reach the locking holes 150a2 and 150a2, the leading ends and the locking surfaces 150a1 and 150a1 interfere with each other, but the locking surfaces 150a1 and 150a1 are bent inward. The advancement of the locking claws 122d1 and 122d1 can be allowed. In addition, since it is the same as that of previous embodiment about the structure other than the above, description is abbreviate | omitted.

  By doing in this way, it becomes possible to connect the temporary fixing parts 122d and 122d and the protection member 150 by the locking claws 122d1 and 122d1. Therefore, after destroying the connection part which connects the front part and base part in a cover plate, the protection member 150 is also moved to the near side by moving the temporary fixing parts 122d and 122d extended from the base part to the near side. Can do. That is, the protection member 150 can be pulled out to the near side. Therefore, the protective member 150 can be reliably and easily removed from the box part 112 whose sealing has been released.

  Further, since the locking claws 122d1 and 122d1 are engaged with the protection member 150 from the outside to the inside, the protection member 150 can be allowed to bend or vibrate inward. Therefore, as in the previous embodiment, the protective member 150 can dissipate external loads as shown in FIG. It should be noted that the temporary fixing portions 122d and 122d do not hinder the inward swinging of the protective member 150 inside the protective member 150, and a locking claw is formed by extending the protective member 150 toward the front side. May be. In this case, a groove or a hole is formed inside the temporary fixing portions 122d and 122d, and the locking claw formed by extending the protective member 150 from the inside to the groove or hole may be inserted. .

  FIG. 23 shows the cover plate according to the third embodiment as viewed from above. In the figure, a cover plate 222 has a configuration substantially similar to that of the first embodiment. However, a pair of connecting portions 222e and 222e that connect the base portion 222b and the tip portion 222a at the end in the width direction extend inward. The pair of connecting portions 222e and 222e cover the temporary fixing portions 222d and 222d extending from the base portion 222b from above. Note that the entire cover plate 222 is transparent, and the temporary fixing portions 222d and 222d are colored red.

  By doing so, it is possible to prevent the temporary fixing portions 222d and 222d from being touched without destroying the connecting portions 222e and 222e visible from the back side of the gaming machine. That is, even if the temporary fixing portions 222d and 222d are destroyed and the protective member is extracted, the traces can be left on the connecting portions 222e and 222e, so that it is possible to find out that there has been fraud at an early stage. Further, even if the temporary fixing portions 222d and 222d are destroyed without destroying the connecting portions 222e and 222e, the colored temporary fixing portions 222d and 222d are easily noticeable, and the abnormalities of the temporary fixing portions 222d and 222d are detected early. can do.

(5) Summary:
As described above, in the gaming machine according to the present invention, when the connecting portions 22c, 22e, and 22e are broken and the lid member 20 is slid forward, the temporary fixing portions 22d and 22d that extend from the base portion 22b are also obtained. It will slide to the near side. Therefore, the retaining of the protective member 50 toward the front side is naturally released. That is, the protection member 50 can be easily removed from the box portion 12 that does not need to be protected from the outside. By doing so, it can be easily recycled. Further, the protection member 50 can be reused by being mounted on another box portion 12.
