According to such a configuration, it is possible to prevent the engagement from being released from the outside by closing the portion where the pin and the pin receiving plate are engaged from the outside by the substantially box-shaped pin receiving portion. Further, by protecting the inner wall surface of the pin receiving portion with a metal piece, it was possible to prevent fraud by making a hole in the wall surface of the pin receiving portion.
JP 2003-209322 A (unpublished application)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 problems, and the protection by the protective member is reliable, and
The object is to provide a gaming machine having a control box with good recyclability.

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.

a and the regulation part 42 hold | maintain the holding pillar 12c from the width direction outer side.

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 bar 42a is slightly smaller than the interval s between the holding column 12c and the holding columns 12e, 12f, the regulating bar 42a, the holding column 12c, and the holding column 1 are formed.
2e and 12f do not interfere with each other. 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 includes the holding pillars 12c to 12f and the wall surface 12b in the box portion 12.
Since it is inserted into each gap formed, and not fixed by engagement or the like, it 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 same figure, the retaining piece 40 is the box portion 1 as in the second mounting state.
2, the holding pillars 12 c to 12 f and the wall surface 12 b are inserted into the respective gaps. 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 held by the holding column 1
Although it will be inserted in the gap between 2c and the back wall surface 12b, the thickness of the frame portion 40c is also the holding column 1
Since it is formed slightly smaller than the distance u between 2c and the back wall surface 12b, it can be inserted without interference.

Therefore, even if the retaining piece 40 is reversed and inserted into the retaining pillar 12c, the retaining pillar 12c and the retaining piece 4 are
0 does not interfere. 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 orthogonal to each other at both ends of the bottom plate 50b in contact with the bottom surface 12a of the box portion 12,
50a is in contact with each of 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 protection member 50 is formed of the holding pillars 12d to 12d
12f and the side wall surfaces 12b and 12b are sandwiched and held in the thickness direction by the gap formed by the side wall surfaces 12b and 12b, but since the gap is formed larger than the thickness, play is formed in the thickness direction. Yes.

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. The rear end of the side plates 50a, 50a is the rear wall 1
When reaching 2b, the end face of the bottom plate 50b where the cutout 50c is formed is formed so as to reach the holding columns 12c, 12d, and 12f. 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 on both outer sides in the width direction.
, 22b1 are formed.

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 are formed of the thin plate portions 22b1 and 22b1 and the thin plate portion 22.
a1 is connected and has the same thickness as these. The thin plate portion 22b1 in the base portion 22b
A rectangular frame-shaped reinforcing rib 22b2 is formed on the inner side of 22b1 with an increased 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 extend downward inside each of the pair of thin plate portions 22b1 and 22b1 in the base portion 22b, and further extend further to the temporary fixing portion 22d.
, 22d substantially reaches the front end 22a. Connecting portion 22c at the tip 22a
A substantially plate-shaped closing plate 22a3 is provided below the portion to be joined to the plate. Closing plate 22a3
Both ends in the width direction 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 has a normal direction opposite to the first engagement guide surface 23b1,
And it is formed so that it may become diagonally behind. Engagement destination 23 at the lower end of the engagement plate 23a
A restriction insertion portion 23c is formed by cutting out the front side of b. Restriction insertion part 23c
Is substantially triangular when viewed from the side, and the inner projecting portion of the restricting tip 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, at the boundary between the lid body 24 and the lid plate 22,
A section screen 24d having a rail insertion portion 24c formed on the side of the cover plate 22 extends downward.

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 12 is the lid plate 2.
2 is a space closed from outside except for the opening on the side of the connecting portion 22c. The thin plate portions 22a1, 22b1, and 22b1 constituting the outer edges of the back and sides of the cover plate 22 are the box portion 1
2 is inserted into a guide portion 12b1 having a substantially U-shaped cross section formed at the upper end of each side surface 12b. Thereby, since the shape of the contact part of the cover plate 22 and the box part 12 becomes complicated, the cover plate 22
It is difficult for foreign matter to enter the inside of the box portion 12 through the gap between the box portion 12 and the box portion 12.

Further, the guide portion 12b1 is arranged so that the lid portion 22 slides with respect to the box portion 12 when the lid portion 22 is slid.
Since the slide is guided across the width direction and up and down, 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 are also slidable on the cover plate 22 and the side wall surfaces 12b and 1 of the box portion 12 together.
It advances toward the back while sliding on each of 2b.

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 are the engagement destination portion 23b and the removal destination portion 41, respectively.
When b is engaged, the side plates 50a and 50a of the protection member 50 come into contact with the front end portions of the side plates 50a and 50a. Thereby, the protection member 50 can be fixed to the near side to prevent it from coming off. Closure plate 2
Both ends in the width direction of 2a3 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. As described above, the engaging portion 23 is inserted at the same height as the window portion 40d, and the height h is almost the same as the retaining portion 41 in the height direction.
For this reason, there is a relationship of interfering with both the retaining portion 41 and the restricting portion 42.
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. The first engagement guide surface 23b1 and the retaining guide surface 41b1 are
Since they are inclined with respect to the advancing direction of the engagement destination portion 23b, both try to push each other out 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 engaged with the engagement destination portion 23.
Since b is a free end, the engagement tip portion 23b bends away from the retaining tip portion 41b. 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. Regulation guide surface 42b of regulation tip part 42b
Since the first and second engagement guide surfaces 23b3 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 portion 23 is formed in a plate shape, the engaging portion 23 cannot be bent except in the normal direction of the engaging portion 23. Therefore, the engaging portion 23 does not bend upward due to interference with the restricting portion 42. In addition, since the regulation tip part 42b is formed at the free end of the regulation part 42 formed in a beam shape,
The amount of displacement 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. The engaging plate 23a and the regulating rod 42a
When the engagement destination portion 23b advances to the back by bending the contact portion 23b, a considerable reaction force is exerted on the engagement portion 23. However, the connecting portion 22c is opposed to the opposite direction of the reaction force on the back surface of the closing plate 22a3. Because we support
The engaging portion 23 can be surely pushed in. That is, the connecting portion 22c can function as a reinforcing rib for the closing plate 22a3.

And, as shown in FIG. 18, when the engagement destination portion 23b passes by the side of the stop destination portion 41b,
The interference between the first engagement guide surface 23b1 and the retaining guide surface 41b1 is eliminated, and the engagement plate 23
a can return to its original shape. 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 into the holding column 12c and attached, the retaining piece 40
Of course, the first engagement surface 23b2 will not move forward. First engagement surface 23
Since the direction in which b2 moves and the direction in which the holding column 12c is inserted into the retaining piece 40 are perpendicular to each other, the retaining piece 40 will not come out of the retaining column 12c even if the first engagement surface 23b2 is moved. Absent. Accordingly, the retaining piece 40 comes out of the holding column 12c, and the retaining piece 4 of the retaining column 12c.
The binding force against zero 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 to cause the second engaging surface 23 to be bent.
c1 and the second restricting surface 42b2 can move without interference, and when the movement is completed, the restricting portion 42 returns to the original shape and the second engaging surface 23c1 and the second restricting surface 42b.
2 can face each other. The second restricting surface 42b2 is the same as the restricting portion 4 in the restricting portion 42.
Since 2 is formed at the free end with a large displacement when bent, the second regulating surface 42b2 can be moved to the back without interfering with the second regulating surface 42b2. 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, the engaging portion 23 is formed in a plate shape, and the engaging portion 2
Since it cannot bend except in the normal direction of 3, the only way to release the engagement is to bend the engaging portion 23 outward. 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. Therefore, FIG.
As shown in FIG. 9, when a hole is drilled in each wall surface 12b or bottom surface 12a of the box portion 12 and the protective member 50 is to be penetrated, the upper ends of the side plates 50a and 50a are bent inward to propel the drill. The direction can be diverted 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 7 is slid by sliding the plate member 10 and the lid member 20.
0 must be opened. 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 contributing to the engagement extends from the front portion 22a, the base portion 22b.
If it is separated from the front portion 22a, the restraining force due to the engagement does not reach the base portion 22b and 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. Further, the connecting portions 22e, 2
In order to break 2e, it is necessary to break both the guide portion 12b1 and the breakage scale is large. Therefore, the opening history of the control box 70 can be visually recognized more clearly. Further, the connecting portions 22e and 22e are not destroyed without the guide portion 12b1 being destroyed.
The guide portion 12b1 is formed transparent so that the breaking state of the connecting portions 22e and 22e can be easily grasped even if only the case is broken, 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,
By breaking the connecting portions 22c, 22e, and 22e to release the sealing, the protection member 50 can be easily removed from the box portion 12 that does not need to be protected from the outside. 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, the retaining piece 40
Therefore, 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 protective member 150 includes a bottom plate 150b and side plates 150a and 150a.
A pair of locking surfaces 150a1 and 150a1 are formed by bending 50a and 150a, respectively. The locking surfaces 150a1 and 150a1 are planes parallel to each other, and the side plates 150a and 150a.
It is opposed to the inner side in the width direction than a. 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 FIG.
A protective member 150 is mounted inside 2, 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. Temporary fixing parts 122d, 122
Locking claws 122d1 and 122d1 are extended from d to the back, respectively.
2d1 and 122d1 also move backward together with the engaging portion 123. Locking claws 122d1, 122
d1 is 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. Locking claws 122d1, 12
Until the tip of 2d1 reaches the locking holes 150a2 and 150a2, the tip and the locking surface 15
0a1 and 150a1 interfere with each other, but the locking claws 122d1 and 122d1 can be allowed to advance by locking the locking surfaces 150a1 and 150a1 inward. In addition, since it is the same as that of previous embodiment about the structure other than the above, description is abbreviate | omitted.

In this way, the temporary locking portions 122d, 122d, by the locking claws 122d1, 122d1
122d and the protection member 150 can be connected. Therefore, after destroying the connection part which connects the front part and base part in a cover plate, the temporary fixing parts 122d and 122d extended from the base part
The protective member 150 can also be moved to the near side by moving the to the near side. 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. The temporary fixing portions 122d, 1 are provided inside the protective member 150.
It is sufficient that 22d does not hinder the inward swinging of the protective member 150, and a locking claw may be formed by extending the protective member 150 toward the front side. 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, the connecting portions 222e and 222e visible from the back side of the gaming machine.
It is possible to prevent hands from being applied to the temporary fixing portions 222d and 222d without destroying. 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, the connecting portions 22c, 22e, 22e
When the cover member 20 is slid to the near side by breaking the cover member 20, the temporary fixing part 2 extended from the base part 22 b
