A cutout 14e penetrating 4b is formed.

FIG. 9 shows the metal piece 50 as viewed obliquely. In the figure, a substantially plate-shaped protective plate 51 is formed on the upper part of the metal piece 50, and a substantially plate-shaped bottom plate 54 is formed so as to face the protective plate 51 substantially in parallel. A narrow portion 51 a is formed in the middle of the protective plate 51 in the depth direction. A side plate 52 that connects the protection plate 51 and the bottom plate 54 is formed so as to be orthogonal to the protection plate 51 and the bottom plate 54. A pair of substantially plate-shaped pin receiving plates 53 a and 53 b are formed substantially perpendicular to the side plate 52 on the outer side in the width direction in the middle of the side plate 52 in the height direction. The pin receiving plates 53a and 53b face each other in the width direction and are substantially parallel to each other. That is,
When viewed from above, the pin receiving plates 53a and 53b and the side plate 52 face each other in a substantially U-shape. Accordingly, the distance between the pin receiving plate 53a and the pin receiving plate 53b facing each other is equal to the width of the side plate 52. The width of the side plate 52 is the constant width portion 14d2 of the engaging portion 14d described above.
It is equivalent to the width of.

By providing substantially square cutouts at the upper and lower portions of the front free ends of the pin receiving plates 53a and 53b, short engaging ends 53a3 and 53b3 are formed in the vertical direction. Pin receiving plate 5
Spring pieces 53a1, 53a2, and 53b are provided at substantially central portions of 3a and 53b toward the outside.
1, 53b2 is formed. The spring pieces 53a1, 53a2, 53b1, and 53b2 are formed by forming two substantially U-shaped cuts in the center of the pin receiving plates 53a and 53b, and the portion surrounded by the cuts is formed outward in the width direction. It is formed by extruding. Since the notch is formed in a substantially U shape, the lower end of the portion surrounded by the notch is the pin receiving plate 5 most.
Separated from 3a and 53b. The spring pieces 53a1, 53a2, 53b1, and 53b2 have spring properties, and repel the external force that pushes inward, trying to restore it outward.

In the present embodiment, the metal piece 50 is obtained by cutting a single metal plate into a predetermined shape,
It is formed by bending. Accordingly, the protective plate 51, the side plate 52, and the pin receiving plate 53a.
53b, the bottom plate 54 and the spring pieces 53a1, 53a2, 53b1, 53b2 are formed as an integral member.

FIG. 10 shows the pin 40 as viewed obliquely. The pin 40 is thicker and more rigid than the metal piece 50. In the figure, a pin 40 is formed in a substantially inverted U shape, so that two substantially rod-shaped tip portions 42a and 42b are formed in the lower portion thereof. Saw blade portions 42a1 and 42a2 are formed at the tip portion 42a, and saw blade portions 42b1 and 42b2 are formed at the tip portion 42b. The saw blade portions 42a1 and 42a2 and the saw blade portions 42b1 and 42b2 face each other inward. The saw blade portions 42a1, 42a2, 42b1, 42b2 are provided at the tip portions 42a, 42.
It is comprised by the surface substantially orthogonal to the axial direction of b, and the slope which cross | intersects acutely, and this slope is orientated so that it may face below. On the other hand, a substantially plate-like projecting portion 44 is formed on the top of the pin 40, and a substantially plate-like pushing surface 44a is formed by bending the projecting portion 44 substantially perpendicular to the tip portions 42a and 42b. is doing.

The sealing portion 70a composed of the pin lid portion 22, the pin receiving portion 12, the pin 40, and the metal piece 50 described above is formed by performing the predetermined assembling work shown in FIGS. It can be fixed relative to the pin receiving portion 12. That is, the lid main body portion 24 integrally molded with the pin lid portion 22 and the dish main body portion 14 integrally molded with the pin receiving portion 12 can be relatively fixed at a position where the control box 70 is closed. .

FIG. 11 a shows the pin receiving portion 12 with the metal piece 50 mounted inside as viewed from above. 11b, FIG. 12a, and FIG. 12b are sectional lines X1, X1 in the pin receiving portion 12 at this time.
Sections at X2 and Y2 are shown. The metal piece 50 is attached by being pushed down from the opening surface 12 c into the pin receiving portion 12.

In FIG. 11a, the protection plate 51 is located above the pin receiving portion 12 and the pin receiving portion 1
2 of the opening surface 12c is substantially covered. However, the site | part in which the narrow part 51a of the protection board 51 was provided is not covered, but the guide grooves 12b1 and 12b2 in the lower pin receiving part 12 are visible. Further, the guide grooves 12b1 and 12b2 are divided by pin receiving plates 53a and 53b, and a pair of substantially rectangular spaces opened upward are formed on both sides in the width direction. The position where the narrow portion 51a of the protective plate 51 is provided and the spring pieces 53a1 and 53a2.
, 53b1 and 53b2 are formed so as to coincide with each other, so that the spring pieces 53a2 and 53b2 formed above are visible from above.

In FIG. 11b, the bottom plate 54 of the metal piece 50 is inscribed in the bottom surface of the pin receiving portion 12,
The side plate 52 is inscribed in the inner surface of the pin receiving portion 12. That is, the bottom plate 54 and the side plate 52 constitute the inscribed plate referred to in the present invention. The protective plate 51 is an opening surface 12c of the pin receiving portion 12.
It is further upward and is separated from the opening surface 12c by a predetermined distance. In FIG. 12a, the pin receiving plates 53a and 53b cross the pin receiving portion 12 in the depth direction, and the locking ends 53a3 and 53b3 at the tips of the pin receiving plates 53a and 53b reach the common wall surface 14b with the plate body 14 and It is engaged with an engaging portion 14d formed on 14b. The locking ends 53a3 and 53b3 are lowered until they pass through the upper stopper 14d1 in the engaging portion 14d and coincide with the height of the constant width portion 14d2.

In FIG. 12b, the locking ends 53a3 and 53b3 of the pin receiving plates 53a and 53b on both sides sandwich the constant width portion 14d2 from the outside. Here, when the metal piece 50 is pulled upward from the pin receiving portion 12, the upper portions of the locking ends 53a3 and 53b3 of the pin receiving plates 53a and 53b abut on the substantially trapezoidal upper retaining portion 14d1 from below, I can't pull it out.
In order to pull the metal piece 50 upward from the pin receiving portion 12, it is necessary to widen the interval between the locking ends 53a3 and 53b3 of the pin receiving plates 53a and 53b as compared with the upper retaining portion 14d1.

As described above, the interval between the locking ends 53a3 and 53b3 is defined by the width of the side plate 52. Since the width of the side plate 52 is equal to the constant width portion 14d2, a metal piece is used to increase the interval. 50 needs to be deformed from its original shape. Therefore, it is difficult to pull the metal piece 50 upward from the pin receiving portion 12. On the other hand, if the bottom surface of the pin receiving portion 12 is completely removed and the metal piece 50 is pulled downward from the pin receiving portion 12, the locking end 53
The lower end of a and 52a interferes with the fall-off preventing portion 14d3 of the engaging portion 14d. Lower drop prevention part 1
Since both ends in the width direction of 4d3 are extended to the side surface of the pin receiving portion 12, the locking end 53a3
, 53b3 cannot be pulled downward from the pin receiving portion 12 even if the interval is widened.

As described above, unless the engaging portion 14d is destroyed, it is very difficult to pull the metal piece 50 once mounted up and down from the pin receiving portion 12. On the other hand, when the metal piece 50 is attached to the pin receiving portion 12, the locking ends 53a3 of the metal piece 50 entering from the opening surface 12c.
The lower end of 53b3 is pushed and spread while sliding along the slope of the generally trapezoidal upper retaining portion 14d1 which is wide downward. Therefore, the metal piece 50 can be mounted while being deformed so as to widen the interval between the locking ends 53a3 and 53b3. In this manner, the pin 40 can be inserted into the pin receiving portion 12 to which the metal piece 50 is mounted. That is, it is easy to attach the metal piece 50 to the pin receiving portion 12, but it is impossible to remove the metal piece 50 by hand from the outside.

However, it is possible to remove the metal piece 50 by hand from the inside of the control box.
Since the notch 14e penetrates the common wall surface 14b, the locking ends 53a3 and 53b3 are exposed inside the control box 70. Therefore, when the control box 70 is opened, the metal piece 50 is made to come into contact with the locking ends 53a3 and 53b3 from the inside of the control box 70 and push the gap therebetween wider than the maximum width of the upper slip-off preventing portion 14d1. It can be pulled upward from the pin receiving portion 12. That is, when the control box 70 is closed, the metal piece 5
Although it is impossible to remove 0, the metal piece 5 is in a state where the control box 70 is opened.
It is possible to remove 0.

FIG. 13 a shows the pin receiving portion 12 when the lid member 20 and the dish member 10 are in the closed position as viewed from above. 13b, FIG. 14a, and FIG. 14b show cross sections taken along the cross sectional lines X1, X2, and Y2 in the pin receiving portion 12 at this time. In FIG. 13 b, the rail insertion portion 24 c of the lid main body portion 24 is sandwiched between the guide rails 14 c of the dish main body portion 14, and the lid main body portion 2.
4 and the plate body 14 form a closed control box 70. At this time, the sealing plate 22
a is inserted between the protective plate 51 and the opening surface 12c of the pin receiving portion 12, and the sealing plate 22a.
As a result, the opening surface 12c of the pin receiving portion 12 is closed. Therefore, the through hole 2 of the sealing plate 22a
Except for 2b1 and 22b2 and the notch 14e of the common wall surface 14b, the inside of the pin receiving portion 12 becomes a closed space with respect to the outside.

Further, the common wall surface 14b is cut out at a predetermined portion to form the engaging portion 14d and a notch 14e is formed. However, as shown in FIGS. 13b and 14b, the rail insertion portion 24c is connected to the common wall surface 14b from the front. Therefore, the notch 14e is also closed from the inside. Therefore, the interior of the pin receiving portion 12 is a space that is completely independent from the interior of the closed control box 70. That is, even if the pin receiving part 12 is destroyed, the foreign matter that tries to enter the control box 70 can be blocked. In addition, rail insertion part 24c
Is extended downward by a predetermined amount, so that the cutout 14e can be completely closed from the inside. Accordingly, it is impossible to contact the locking ends 53a3 and 53b3 from the inside of the control box 70. In this state, the metal piece 50 cannot be completely pulled out from the pin receiving portion 12. Since the rail insertion part 24c closes the notch 14e from the inside, it constitutes a blocking part according to the present invention.

On the other hand, the through holes 22b1 and 2b formed in the sealing plate 22a in FIGS. 13a and 14a
2b2 includes guide grooves 12b1 and 12b2 of the pin receiving portion 12 and a narrow width portion 51a of the protection plate 51.
And the positions of the spring pieces 53a1, 53a2, 53b1, 53b2 of the pin receiving plates 53a, 53b in the depth direction all coincide. That is, a pair of openings for inserting the tip portions 42a and 42b of the pin 40 are formed, and the tip portions 42a and 4 are formed below the openings.
Spring pieces 53a1, 53a2, 53b1, and 53b2 for biting into the saw blade portions 42a1, 42a2, 42b1, and 42b2 formed on 2b are respectively positioned.

FIG. 15 a shows the pin receiving portion 12 with the pin 40 inserted into the pin receiving portion 12 as viewed from above. 15b and FIG. 16 are sectional lines X1, X1 in the pin receiving portion 12 at this time.
A cross section at Y2 is shown. 15a and 15b, the pushing surface 44a of the pin 40 is substantially parallel to the sealing plate 22a and the protective plate 51, and covers these back portions from above. The outer edge of the pushing surface 44a reaches a position almost in contact with the protective wall 22d, and the entire pushing surface 44a is accommodated in a space surrounded by the protective wall 22d.

In FIG. 16, the tip portions 42 a and 42 b of the pin 40 enter the inside of the pin receiving portion 12 while traversing the through holes 22 b 1 and 22 b 2 and the narrow width portion 51 a of the protection plate 51. On the other hand, the protruding portion 44 of the pin 40 protrudes outside the protective plate 51. Tip portions 42a, 42
b sandwiches the pin receiving plates 53a and 53b from the outside. At this time, the pin receiving plate 53a
, 53b projecting from the spring pieces 53a1, 53a2, 53b1, 53b2
2a1, 42a2, 42b1, and 42b2 are bite into the back.

When the tip portions 42a, 42b enter from above, the spring pieces 53a2, 53a1, 53b
2, 53b1 are the tip portions 42a, 42 of the saw blade portions 42a1, 42a2, 42b1, 42b2.
It contacts an inclined surface that intersects the axis direction of b at an acute angle, and is pushed inward so as to follow this. When the saw blade portions 42a1, 42a2, 42b1, 42b2 pass, the spring piece 5
3a2, 53a1, 53b2, 53b1 are restored to their original shapes, and saw blade portions 42a1, 42a2
, 42b1 and 42b2. Therefore, when the pin 40 is subsequently pulled out, the lower ends of the spring pieces 53a2, 53a1, 53b2, 53b1 are connected to the saw blades 42a1, 4b.
2a2, 42b1, and 42b2 are in contact with the surfaces substantially perpendicular to the tip portions 42a and 42b, respectively.

By doing so, the pin 4 can be used as long as the pin receiving plates 53a and 53b are not broken.
It is possible to make it impossible to pull out 0. In addition, since the pin 40 is thick and has high rigidity, it is difficult to be broken or deformed. When the front end portions 42a and 42b enter from above, the guide grooves 12b1 and 12b2 guide the front end portions 42a and 42b from the outside, and the pin receiving plates 53a and 53b slide in contact with the front end portions 42a and 42b from the inside.
Therefore, the pin 40 can be inserted into a predetermined position in a stable state. Further, since the pin 40 is provided with a pushing surface 44a perpendicular to the insertion direction, the pin 40
Can be pushed in easily.

Here, the pin receiving plates 53a and 53b only have to be able to retain and hold the tip portions 42a and 42b, and may have other configurations. For example, the spring pieces 53a2, 53a1, 53b2
Instead of 53b1, rectangular holes may be formed at the locations where the spring pieces 53a2, 53a1, 53b2, 53b1 are provided. In this case, the saw blades 42a1, 4 are inserted into the rectangular holes.
2a2, 42b1, 42b2 enter from the outside, and the upper side of the rectangular hole and the saw blade portions 42a1, 4
The front end portions 42a and 42b can be prevented from coming off by interference with the surfaces substantially perpendicular to the front end portions 42a and 42b of 2a2, 42b1 and 42b2. Further, when the saw blade portions 42a1, 42a2, 42b1, 42b2 enter the same rectangular hole from the outside, the pin receiving plates 53a, 53b themselves are deformed so as to bend inward, and return to the original shape when they have completely entered. To do. That is, by utilizing the spring property of the pin receiving plates 53a and 53b itself, the tip end portion 42a.
42b can also be retained.

When the pin 40 is inserted in this manner, the pin 40 becomes a pin and the pin lid portion 22 is inserted.
The protection plate 51 cannot move with respect to the pin receiving portion 12. That is, even if the pin lid portion 22 is slid in the depth direction, the pin 40 and the through holes 22b1, 22b2
Therefore, the pin lid 22 cannot be slid in the depth direction.
On the other hand, even if the pin lid portion 22 is moved upward, the protruding portion 44 of the pin 40 does not move through the through hole 22.
Since the projections 44 are formed larger than b1 and 22b2, the projecting portion 44 has the sealing plate 22a and the protective plate 51.
Interference from above. In particular, in this embodiment, by forming the pin 40 in a substantially U shape, the pin 40 has a single retaining strength that is double that of the single pin 40 and is sandwiched between the through holes 22b1 and 22b2 in the sealing plate 22a. Since the above-mentioned part is held in and fixed, the lid member 20 and the dish member 10 can be fixed more firmly.

Further, a protective plate 51 is interposed between the sealing plate 22 a and the protruding portion 44. Therefore, even when an excessive load is applied to open the pin lid portion 22 upward, the protective plate 51 protects the load while being distributed over a wide range of the sealing plate 22a, so that the synthetic resin sealing plate is used. The 22a is prevented from being damaged. Further, a protective plate 51 that covers the sealing plate 22a from above.
Is integrated with the metal piece 50. Therefore, since the protective plate 51 is also held on the pin receiving portion 12 side, the sealing plate 22a can be restrained on the pin receiving portion 12 side also by the protective plate 51.

When the periphery of the through holes 22b1 and 22b2 in the sealing plate 22a is broken, the pin 40 cannot restrain the pin lid portion 22. For example, through holes 22b1, 22b2
By destroying the sealing plate 22a so that the diameter of the hole is larger than that of the protruding portion 44, the pin lid portion 22 can be moved upward. Further, the through holes 22b1 and 22b2 are formed on the sealing plate 2.
If the sealing plate 22a is broken so as to extend to the back end of 2a, the pin lid portion 22 can slide in the depth direction. However, since the sealing plate 22a is protected from above by the metal protection plate 51, the sealing plate 22a cannot be directly destroyed.

On the other hand, the pushing surface 44 a is accommodated in a space surrounded by the protective wall 22 d of the pin lid portion 22. Further, as shown in FIG. 15a, since the pushing surface 44a is fitted so that the outer edge thereof is substantially in contact with the protective wall 22d, the projecting portion 44 of the pin 40 on which the pushing surface 44a is formed is tried to be picked with pliers or the like. However, the protective wall 22d obstructs this. Therefore, the protrusion 4 of the pin 40
It is difficult to pick 4 with pliers or the like, and the pin 40 cannot be forcibly pulled out.

Here, when the pin receiving plate 53a and the pin receiving plate 53b are deformed so as to approach each other, the spring pieces 53a1, 53a2, 53b1, 53b2 are saw blade portions 42a1, 42a2, 4.
The amount of biting into the back of 2b1 and 42b2 is reduced, and the pin receiving state is weakened.
Then, the pin 40 can be pulled upward. However, the pin receiving plates 53a and 53
The locking ends 53a3 and 53b3, which are free ends of b, hold the engaging portion 14d inward and cannot approach each other any more. Therefore, the pin receiving state with the pin 40 is also prevented from being weakened.

Further, the pin receiving plates 53 a and 53 b are accommodated in a space closed by the pin receiving portion 12 and the pin lid portion 22. Therefore, unless the wall surface of the pin receiving plate 12 is destroyed, the pin 40 cannot be removed from the outside by destroying or deforming the pin receiving plates 53a and 53b.

Moreover, in this embodiment, since the wall surface of the pin receiving plate 12 is protected from the inside by the metal piece 50, it is difficult to destroy the wall surface of the pin receiving plate 12. Specifically, when a foreign object is to enter from the bottom surface side of the pin receiving portion 12, the metal bottom plate 54 prevents this. The bottom plate 54 can also block foreign matter entering from the bottom side to push up the pin 40 from the tip side, and therefore it is impossible to push up the pin 40 from the tip side. Even if it is going to make a foreign material penetrate | invade from the back | inner side surface of the pin receiving part 12, the side plate 52 prevents this.

Further, even if a foreign object enters from the outside in the width direction to destroy or deform the pin receiving plates 53a and 53b, the tip of the highly rigid pin 40 protects the pin receiving plates 53a and 53b from the outside. The receiving plates 53a and 53b cannot be broken or deformed. Protective plate 51
The side plate 52, the pin receiving plates 53a and 53b, and the bottom plate 54 are formed by bending a single metal plate at a substantially right angle, so that the rigidity of the metal piece 50 as a whole is high and deformed by the intrusion of foreign matter or the like. It's harder to be let down.

Furthermore, even if it is going to destroy the sealing plate 22a in order to make a foreign material penetrate | invade from the outer side of the sealing plate 22a, the metal pushing surface 44a prevents this first. Even if the sealing plate 22a is to be destroyed from the gap between the pushing surface 44a and the protective wall 22d, the metallic protective plate 51 protects the sealing plate 22a, and therefore the sealing plate 22a cannot be destroyed. Further, even if the protective plate 51 is to be removed by turning it up or the like, the protective wall 22d surrounds the protective plate 51 and cannot be removed easily. Therefore, the sealing plate 22a cannot be destroyed. Since the wall surface on the front side of the pin receiving portion 12 is shared with the wall surface 14b of the dish main body portion 14, the common wall surface 14b and the engaging portion 14d formed on the common wall surface 14b cannot be destroyed from the outside. Accordingly, a foreign material or the like enters the pin receiving portion 12 from any external direction to cause the pin receiving plate 53a to enter.
, 53b cannot be destroyed and the pin 40 cannot be removed.

As described above, it has been described that the pin 40 is difficult to be pulled out as an effect of the present invention. However, according to the present invention, it is possible to prevent the metal piece 50 from being pulled out from the pin receiving portion 12. In other words, by first removing the metal piece 50, it is possible to prevent fraud in which the retaining of the pin 40 is released. In particular, the pin receiving portion 12 provided with the metal piece 50 is located below the pin lid portion 22 and is difficult to visually recognize. Therefore, the metal piece 50
There is also a problem that even if the pin receiving portion 12 is broken to remove the trace, it is difficult to find the trace.

Hereinafter, it will be described that the metal piece 50 is difficult to be extracted from the pin receiving portion 12 as an effect of the present invention. Since the engaging portion 14d with which the metal piece 50 engages is formed on the common wall surface 14b of the control box 70, the engaging portion 14d can be destroyed no matter how much the pin receiving portion 12 extended outside the control box 70 is destroyed. Cannot be destroyed. That is, unless the control box 70 itself is destroyed or the control box 70 is not opened, it is impossible to destroy the engaging portion 14d and extract the metal piece 50. Even if the metal piece 50 can be extracted, the trace of destruction becomes large, so that it is possible to immediately find out that there was an injustice.

Further, the metal piece 50 is engaged with the pin 40 by the pin receiving plates 53a and 53b, and the protective plate 51 on the sealing plate 22a is fixed to the pin 40 by the narrow width portion 51a. Yes. Accordingly, the engagement portion 14d is temporarily broken and a hole is made in the bottom surface of the pin receiving portion 12, so that the metal piece 5
Even if it tries to pull out 0 downwards, considerable force is required. The protective plate 5
Since 1 is also removed together, it can be easily recognized that the metal piece 50 has been pulled out from below. Although it is conceivable that only the protective plate 51 is separated from the metal piece 50 and only a portion that cannot be visually recognized is extracted, the protective wall 22d surrounds the protective plate 51, so that it cannot be easily separated. Further, since the pushing surface of the pin 40 protects the upper side of the protective plate 51, it is difficult to separate the protective plate 51.

Further, as described above, in order to extract the metal piece 50 from the pin receiving portion 12 without destroying the engaging portion 14d, it is necessary to increase the distance between the pin receiving plates 53a and 53b. But,
As shown in FIG. 16, in a state where the pin 40 is inserted, the pin receiving plates 53 a and 53 b are restrained inside by the pin 40, so that it is impossible to widen the interval between them. Accordingly, the metal piece 50 is prevented from being extracted from the pin receiving portion 12.

As described above, in this embodiment, it is very difficult to remove the pin 40 and the metal piece 50 and release the fixation of the lid member 20 and the dish member 10. However, the sealing part 7
If 0a is uprooted and separated from the control box 70, the sealing portion 70a cannot fix the lid member 20 and the dish member 10 without removing the pins 40 and the metal pieces 50.
However, when the plate main body 14 and the pin receiving portion 12 constituting the control box 70 are separated, the metal piece 50 needs to be cut. That is, since the metal piece 50 crosses from the pin receiving portion 12 to the engaging portion 14d formed on the wall surface 14b of the dish main body portion 14, the pin receiving portion 1
In order to detach 2 from the outside of the pan body 14, the metal piece 50 must be cut. Therefore, the pin receiving part 12 cannot be easily separated from the dish main body part 14. Of course, it is possible to separate the pin receiving part 12 from the dish member 10 by destroying the entire wall surface of the dish main body part 14, but in this case, a large-scale destruction is required, and the trace becomes conspicuous.

Further, there are many cases where only the pin receiving portion 12 used (pin 40 is inserted) is tried to be separated so that a small-scale destruction in which an improper trace is not conspicuous is sufficient. In particular, the pin receiving portion 12 is positioned below the lid portion 22 and is difficult to find a trace of destruction, and thus is easily targeted. FIG. 17 shows the sealing portion 70a as seen from an oblique direction. In the same figure, the broken line B1 at the time of trying to isolate | separate only the pin receiving part 12 currently used is shown. In the present embodiment, since the adjacent pin receiving portions 12 are connected to each other, many parts must be cut as indicated by the breaking line B1. Therefore, it is difficult to make the traces inconspicuous while separating only the pin receiving portion 12 being used. Furthermore, since the confirmation part 12a is also connected with the adjacent pin receiving part 12, the breaking line B1 will be formed also in the confirmation part 12a. The breaking line B1 in the confirmation portion 12a extended to a position where it can be visually recognized is easy to visually recognize,
You can easily recognize that there was fraud.

Further, if only the pin receiving portion 12 that is used without breaking the confirmation portion 12a is to be cut off, it must be cut as shown by the breaking line B2, and a great number of portions need to be cut. . As described above, it is very difficult to separate the pin receiving portion 12 being used, and the separated traces are easily noticeable. Therefore, it is very difficult to add a fraud to the control board 25, and it can be easily recognized that the fraud has occurred.

By the way, when the control board 25 is maintained, it is necessary to open the control box 70 as shown in FIG. In this case, the lid member 20 may be slid strongly toward the front in the depth direction. In FIG. 17, the breaking line B3 when the lid member 20 is slid strongly toward the front in the depth direction is shown. A thin portion 26 forming a connecting portion between the pin lid portion 22 and the lid main body portion 24 is broken, and a breaking line B3 is formed in the thin portion 26. That is, since the thin portion 26 formed with a small cross-sectional area is easier to break than other portions, only the thin portion 26 is broken. When the thin portion 26 is broken, the pin lid portion 22 is separated from the lid member 20, and thereafter, the lid member 20 can slide in the depth direction. Accordingly, the control board 25 can be maintained.

Moreover, since the thin part 26 is formed in the position which can be visually recognized from the outside, the fracture | rupture state can be confirmed easily. Therefore, the history of opening the control box 70 can be grasped, and it can be easily known whether there has been an unauthorized opening other than maintenance. Once opened, the pin lid portion 22 and the pin receiving portion 12 corresponding to the pin lid portion 22 and the pin receiving portion 12 corresponding to the pinned portion 22 connected by the broken thin portion 26 cannot be used again. And the control box 7 again by the spare pin accommodated in the spare pin accommodation box 13.
0 can be closed.

In the state where the control box 70 is opened, the rail insertion portion 24c is notched 14e.
Therefore, the notch 14 e is exposed to the control box 70. Accordingly, it is possible to remove the metal piece 50 by pushing the locking ends 53a3 and 53b3 of the metal piece 50 mounted on the pin receiving portion 12 that has been used from the inside of the control box 70. Therefore, the synthetic resin dish member 10 and the unnecessary metal piece 50 can be separated and discarded. Furthermore, since the plate member 10 is not destroyed at all, it can be reused. In the state where the control box 70 is closed as shown in FIG.
Since the cover is covered by 3, the spare pin is not lost due to mischief or the like.

(4) Second embodiment:
FIG. 18 shows the rail insertion portion 124c and the common wall surface 114b according to the second embodiment as viewed obliquely. Note that. In the present embodiment, the lid portion and the pin receiving portion are the same as in the first embodiment, and are not shown. In the figure, a pair of substantially rectangular fitting portions 124c1 and 124c2 are formed so as to protrude rearward from the rail insertion portion 124c. The configuration is the same as that of the first embodiment except that the fitting portions 124c1 and 124c2 are formed. A substantially rectangular notch 11 is formed on the common wall 114b to form an engaging portion 114d.
A pair of 4e1 and 114e2 is provided. The fitting portions 124c1 and 124c2 are formed with a slightly smaller height and width than the notches 114e1 and 114e2.
Then, the rail insertion portion 124c is slid so as to come into contact with the common wall surface 114b, whereby the control box is closed and the insertion portions 124c1 and 124c2 are fitted into the notches 114e1 and 114e2, respectively.

At this time, the fitting portions 124c1 and 124c2 have the same depth position as the engaging portion 114d.
Then, since the configuration of the pin receiving plate is the same as that of the first embodiment, as shown in FIG. 19, the locking end 153a of the pin receiving plate holding the engaging portion 114d from the outside in the width direction, 153b
3 is sandwiched between the engaging portion 114d and the fitting portions 124c2 and 124c1. In other words, the pin receiving plate is engaged with the engaging portion 114d while being sandwiched between the fitting portions 124c1 and 124c2 and the engaging portion 114d. Therefore, in the present embodiment, the pin receiving plate can be more firmly fixed to the pin receiving portion, and the sealing state can be prevented from being released due to the pin receiving plate being pulled out.

Further, since the fitting portions 124c1 and 124c2 are fitted into the cutouts 114e1 and 114e2, an intricate structure is formed, so that it is difficult to allow a wire or the like to enter the inside of the control box from the pin receiving portion.

(5) Summary:
As described above, in the gaming machine according to the present invention, the pin receiving portion provided outside the control box and the notch that communicates the inside of the control box are closed by the rail insertion portion serving as a blocking portion. The sealing property of the box can be improved. That is, since the control box becomes an independent closed space, it is impossible to allow foreign matter or the like to enter the control box even if the pin receiving portion is broken. Therefore, it is possible to provide a gaming machine including a control box that is less likely to be cheated.
