Each box part 12 communicates with the dish body part 14 by the notch 14c1, but the dish body part 14 itself is also closed by the lid body part 24 as described above. Can be closed from the outside.

The sealing part 70a for maintaining the control box 70 in a state closed from the outside is the box part 1
2 and the cover plate 22 and the like. And improper such as replacing ROMs 26a to 26f of the control board 25 is prevented by preventing the fixing by the sealing portion 70a from being easily released. However, since it is necessary to perform maintenance or the like of the control board 25, the fixing by the sealing portion 70a can be released as necessary, and the release trace can be clearly recognized. That is, it is possible to determine whether or not unauthorized fixing has been performed by referring to the trace of the unlocking in the sealing portion 70a and the record of maintenance or the like that is regularly performed by the administrator. Yes. The detailed mechanism and the like of the sealing portion 70a will be described in detail below.

(3) About the sealing part concerning 1st embodiment:
First, the box part 12 which comprises the sealing part 70a is demonstrated. FIG. 5 shows one of the box portions 12 as viewed from above, and FIG. 6 shows the X1 cross section of the box portion 12 as viewed. The box portion 12 is roughly constituted by a plate-like bottom surface 12a and a wall surface 12b that partitions the box portion 12 from the back and both outer sides in the width direction. At the upper end of the wall surface 12b, a guide portion 12b1 having a groove formed in a substantially U-shaped cross section is formed on the inner side and the outer side in the width direction. Since the notch 14c1 is formed on the near side (the dish body 14 side) of the box part 12, the dish body part 14 and the box part 12 communicate with each other. Note that all five box portions 12 have the same shape.

Inside the box portion 12, substantially columnar holding columns 12 c to 12 f are erected substantially vertically from the bottom surface 12 a upward. The holding columns 12c and 12d are formed so that the central portion in the depth direction can be bundled when viewed from above, and both have the same shape. Holding column 12d
Is formed at a position spaced apart from the side wall surface 12b in the width direction by a distance t, and is formed at a depth position separated from the rear wall surface 12b by a distance u. The holding column 12c is spaced from the holding column 12d by a distance s.
And the depth position is the rear wall surface 1 like the holding column 12d.
The position is separated from 2b by an interval u. The pair of wide portions 12c1 and 12c1 on both outer sides in the depth direction of the holding column 12c are formed to have a width r.

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

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

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

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

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

By configuring the box part 12, the retaining piece 40, and the protective member 50 as described above, the retaining piece 4 is provided.
0 and the protective member 50 can be attached to the box portion 12. FIG. 9 shows a state where the retaining piece 40 is attached to the box portion 12. In the figure, a holding column 12 is provided inside the box portion 12.
A retaining piece 40 is inserted from above so as to surround c. In other words, the retaining plate 41 is formed so that the distance between them is slightly larger than the pair of wide portions 12c1 and 12c1 of the holding column 12c.
a and the regulation part 42 hold | maintain the holding pillar 12c from the width direction outer side.

At that time, since the thickness of the retaining plate 41a is slightly smaller than the interval s between the retaining column 12c and the retaining column 12d, the retaining plate 41a, the retaining column 12c, and the retaining column 12d do not interfere with each other. . Similarly, since the thickness of the regulating rod 42a is slightly smaller than the interval s between the holding column 12c and the holding columns 12e, 12f, the regulating rod 42a, the holding column 12c, and the holding 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.

In addition, the insertion hole of the retaining piece 40 through which the holding column 12c is inserted has a symmetrical shape on a plane indicating the orbit of the midpoint in the depth direction of the retaining piece 40, and the holding column 12c is also in the depth direction of the retaining column 12c. It has a symmetrical shape on the plane showing the trajectory of the middle point. 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 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. Since the predetermined cutout 50c is formed in the bottom surface plate 50b, the bottom surface plate 50b and the holding pillars 12c to 12f do not interfere with each other. Side plate 5
When the rear end portions of 0a and 50a reach the rear wall surface 12b, the end face of the bottom plate 50b where the notch 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. 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. An engagement surface 23b2 that is orthogonal to the engagement plate 23a and faces the closing plate 22a3 is formed at the front end of the engagement destination portion 23b. A second engagement guide surface 23b3 is formed at the lower end of the engagement destination portion 23b.

The second engagement guide surface 23b3 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. The wall surface of the restriction insertion portion 23c substantially parallel to the closing plate 22a3 is referred to as a restriction insertion surface 23c1. On the other hand, a section screen 24 d in which a rail insertion portion 24 c is formed on the side of the lid plate 22 extends downward at the boundary between the lid body portion 24 and the lid plate 22.

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

When the lid plate 22 slides together with the lid member 20, the rear end portion of the lid plate 22 reaches the rear wall surface 12 b of the box portion 12 and closes the upper opening of the box portion 12. That is, the inside of the box 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 slides relative to the box portion 12.
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 engagement surface 23b2 that faces the front side in the engagement destination portion 23b and the retaining surface 41b2 that faces the rear side in the withdrawal destination portion 41b face each other, and the engagement surface 23b2 moves to the front side. No longer allowed.

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

On the other hand, the temporary fixing portions 22d and 22d that move toward the back while sliding on the side wall surfaces 12b and 12b of the box portion 12 together with the sliding of the cover plate 22 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 prevented from coming off to the near side. Closure plate 22a
3 are substantially in contact with the side plates 50a and 50a of the protection member 50 from the inside, and the lower end of the closing plate 22a3 is substantially in contact with the bottom plate 50b of the protection member 50. Thereby, when the engagement destination part 23b and the retaining part 41b are engaged, the box part 12 positioned below the front part 22a.
Can be closed from 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 near side, and the first engagement guide surface 23b1 contacts the retaining guide surface 41b1 of the retaining tip portion 41b. Since the first engagement guide surface 23b1 and the retaining guide surface 41b1 are inclined with respect to the advancing direction of the engagement destination portion 23b, both try to push each other outward in the width direction while sliding. Accordingly, the retaining plate 41a tries to bend outward, but the holding column 12f is in contact with the outside, so that the original shape is maintained. On the other hand, the engagement plate 23a is connected to the engagement destination portion 2.
Since 3b becomes a free end, the engagement destination portion 23b bends away from the retaining portion 41b.

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 restricting rod 42a is supported by the holding column 12d from the outside in the width direction, the restricting rod 42a is bent so as to displace the restricting tip portion 42b downward.

As described above, when the engagement plate 23a and the regulation rod 42a are bent in the respective directions, the engagement destination portion 23b can be further advanced. 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 engagement surface 23b2 that faces the front side in the engagement destination portion 23b and the retaining surface 41b2 that faces the rear side in the retaining portion 41b face each other, and the engagement surface 23b2 moves to the front side. No longer allowed. The retaining piece 40
Is attached to the holding column 12c by being inserted through the inside thereof.
b2 does not move to the near side. Direction of engagement surface 23b2 and retaining piece 40
Since the insertion directions through which the holding columns 12c are inserted are perpendicular to each other, the retaining piece 40 does not come out of the holding columns 12c even if the engaging surface 23b2 is moved. 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 restriction insertion surface 23c1 that faces the front side in the restriction insertion portion 23c and the second restriction surface 42b2 that faces the back in the inner projecting portion of the restriction destination portion 42b face each other, and the restriction insertion surface 23c1 is formed. Moving to the near side is not allowed. That is, it is possible to prevent the engaging portion 23 from moving to the near side at the two locations of the engaging surface 23b2 and the restriction insertion surface 23c1. That is, the engaging portion 23 is engaged with the retaining piece 40 at two locations.

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

Furthermore, as described above, the space in which the engaging portion 23, the retaining portion 41, and the restricting portion 42 that contribute to the engagement are accommodated from the outside by the lid plate 22, the bottom surface 12a of the box portion 12, each wall surface 12b, and the closing plate 22a3. Since it is closed, the engagement cannot be released from the outside by acting on the engagement destination portion 23b and the removal destination portion 41b. In addition, the space in which the engaging portion 23, the retaining portion 41, and the regulating portion 42 that contribute to the engagement are accommodated is protected from below and from the side by the metal protection member 50, 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 merely inserted loosely inside the box portion 12, leaving room for deformation and swinging. 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. In addition, the propulsion direction of the drill is deflected upward, and the side plate 50a
, 50a can vibrate and dissipate the propulsive force of the drill.

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

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

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.

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 portion 22c and releasing 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, the used plate member 10 has a synthetic resin tip 22.
Only a and the retaining piece 40 remain. 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. Further, as the protective member 50, another box portion 1 is used.
2 can be reused.

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) Regarding the second embodiment:
FIG. 21 shows the box portion 112 according to the second embodiment as viewed from above. In the drawing, the retaining portion 141 is extended from the box portion 112. That is, in this embodiment, the retaining portion 141 is not detachable from the box portion 112. However, the retaining portion 141 can be brought into a second state in which the retaining portion 141 is not engaged with the engaging portion 123 by fitting the engagement preventing member 145 formed in an inverted U shape from above. The interval inside the engagement preventing member 145 is the retaining portion 14.
It is formed slightly larger than the thickness of the one retaining plate 141a, and the engagement preventing member 145 can be fitted into the retaining plate 141a from above.

The engagement preventing member 145 is in contact with the retaining surface 141b2 of the retaining portion 141 so as not to generate a gap, and is formed thicker than the width of the retaining surface 141b2. Therefore,
Even if the engagement destination portion 123b of the engagement portion 123 advances until it passes through the retaining destination portion 141b, the engagement destination portion 123a interferes with the engagement preventing member 145, and the engagement portion 123 returns to the original shape. It is not possible. That is, the engagement surface 123b2 of the engagement destination portion 123b and the retaining surface 14 of the retaining portion 141.
Since 1b2 is not faced back and forth, the engaging part 123 and the retaining part 141 can be prevented from engaging.

On the other hand, when it is desired to engage the engaging portion 123 and the retaining portion 141, the engagement preventing member 145 may be removed. By doing in this way, when the engagement part 123b of the engagement part 123 passes through the retaining part 141b, the engaging part 123 can return to the original shape without being obstructed, and the retaining part 141 and Can be engaged. That is, by removing the engagement preventing member 145, the retaining portion 141 can be brought into a first state that can be engaged with the engaging portion 123. In the present embodiment, a restricting portion that prevents bending of the engaging portion 123 after engagement is not formed. Since the configuration other than the above is the same as that of the first embodiment, a description thereof will be omitted.

(5) Regarding the third embodiment:
FIG. 22 shows the protective member according to the third embodiment as viewed from an oblique direction. In the same figure, the protection member 250 is formed by bending a metal plate material as in the first embodiment. The protection member 250 includes a pair of side plates 250a and 250a that are substantially plate-like and parallel to each other, and a substantially plate-like bottom plate 250b that connects them, and the bottom plate 250b has a substantially rectangular notch 250c. Is formed. A portion of the bottom plate 250b where the notch 250c is provided is cut upward to push the vertical wall 250d perpendicular to the bottom plate 250b.
And a holding wall 250e. The pushing wall 250d is perpendicular to the side plates 250a and 250a, and the holding surface 250e is parallel to the side plates 250a and 250a.

FIG. 23 shows the box portion according to the third embodiment as viewed from above. In the drawing, the protection member 250 is shown attached to the box portion 212. Also in this embodiment, the retaining portion 241 is formed integrally with the box portion 212 as in the second embodiment. The retaining portion 241 is formed in a substantially plate shape, and a constricted portion 246 having a right isosceles triangular shape as viewed from above is formed from the inner side in the width direction. The upper rhombus portion formed on the tip side of the constriction 246 is a retaining portion 241b, and the substantially plate-like portion at the back of the constriction 246 is a retaining plate 241a.
It shall be said. The pair of acute angles of the stopper part 241b is 45 degrees, and the obtuse angle of the same pair is 135 degrees. In the state shown in the figure, the protective member 250 is not inserted to the innermost position in the box portion 212, and the pushing wall 250d does not reach the retaining portion 241b.

FIG. 24 shows a state in which the protection member 250 is further advanced from the state of FIG. In the same figure, the thinnest part of the constriction 246 is bent so that the stopper part 241b is rotated 90 degrees from the state of FIG. At this time, the pushing wall 250d is in contact with the rotated stopper portion 241b from the front side. That is, when the protective member 250 advances to the back, the pushing wall 250d abuts against the stopper portion 241b from the near side and pushes the stopper portion 241b inward. As a result, the stopper portion 241b can be rotated 90 degrees with the tip directed inward in the width direction. In addition, since the holding wall 250d is erected on the outer side in the width direction of the stopper part 241b, the stopper part 241b cannot be rotated outward.

By doing in this way, it can be set as the shape which can engage the securing part 241 with the engaging part 223. FIG. In other words, the retaining portion 241b rotates 90 degrees to form a retaining surface 241b2 that faces the back of the engaging portion 223 in the sliding direction.
The engagement can be performed by causing 2 to face the engagement surface 223b2 formed on the engagement portion 223. Therefore, it can be said that the retaining portion 241 in FIG. 24 is in the first state in which the engagement portion 223 can be engaged. On the other hand, the stopper part 241b in FIG. 23 does not interfere even when the engaging part 223 is inserted, and therefore cannot be engaged. Therefore, it can be said that the retaining portion 241 in FIG. 23 is in a second state in which it cannot engage with the engaging portion 223.

As described above, according to the present embodiment, the first state and the second state can be switched even if a part of the retaining portion 241 is deformed so as to rotate. Furthermore, when switching from the second state to the first state, it is only necessary to attach the protective member 250, and the number of operations is not particularly increased. That is, since the protection member 250 is always attached to the box portion 212 to be engaged, the retaining portion 241 is inevitably switched from the second state to the first state.

Since the pushing wall 250d and the holding wall 250d support the retaining portion 241 from the front side and the outer side in the width direction, respectively, the retaining portion 241 returns to the original shape or bends during engagement, and the engagement is released. There is no end to it. Further, when the protective member 250 moves to the near side during the engagement, the pushing wall 250d cannot support the retaining portion 241 from the near side, but it is protected during the engagement as in the first embodiment. Since the member 250 can be prevented from coming off to the near side by the temporary fixing portion, the retaining portion 241 can be reliably supported by the pushing wall 250d. Since the configuration other than the above is the same as that of the first embodiment, a description thereof will be omitted.

(6) About the fourth embodiment:
FIG. 25 shows the protective member according to the fourth embodiment as viewed obliquely. In the same figure, the protection member 350 is formed by bending a metal plate material as in the first embodiment. The protective member 350 includes a pair of side plates 350a and 350a that are substantially plate-like and parallel to each other, and a substantially plate-like bottom plate 350b that connects them, and the bottom plate 350b has a substantially rectangular notch 350c. Is formed. A rectangular plate-shaped guide wall 350f is vertically raised from the side edge of the notch 350c. The guide wall 350f is inclined at an acute angle with respect to the side plate 350a so that the distance from the side plate 350a is narrowed toward the tip.
Further, the guide wall 350f and the side plate 350a are joined at the tip.

FIG. 26 shows the retaining piece according to the fourth embodiment as viewed obliquely. In the figure,
The retaining piece 340 is formed in a substantially L shape by the plate-shaped sliding contact portion 340 and the retaining plate 341a being orthogonal to each other. At the tip of the retaining plate 341a, as in the first embodiment, the retaining portion 341b.
Is formed. On the other hand, a rectangular projecting portion 343 is formed at the lower end of the retaining plate 341a opposite to the projecting direction of the retaining tip portion 341b. A rail groove 343a is formed in the protruding portion 343 from the lower surface to the upper side, and the rail groove 343a is inclined with respect to the retaining plate 341a.

FIG. 27 shows the box portion according to the fourth embodiment as viewed from above. In the drawing, the protection member 350 is attached to the box 312. A side portion of the notch 350c in the bottom plate 350b extends toward the back, and the extended portion is formed so that the width at the back gradually becomes narrower. And the guide wall 350f is standingly arranged in the inner edge part of the extension part. Therefore, the guide wall 350f is inclined with respect to the insertion direction of the protection member 350 indicated by the arrow.

A guide wall 350f enters the rail groove 343a in the protruding portion 343 from below. At this time, the retaining plate 341 a is parallel to the insertion direction of the protection member 350, and the sliding contact portion 340 c perpendicular to this is in contact with the rear wall surface 312 b of the box portion 312. That is, the guide wall 350f and the rail groove 343a are formed to be inclined at the same angle. Box part 31
A holding column 312c is erected from the bottom surface 312a of the second column.
The retaining piece 340 enters a gap formed between the two wall surfaces 12b. The gap is the retaining piece 3
Since it is formed larger than 40, the retaining piece 340 can move inside the box portion 312.

FIG. 28 shows a state in which the protection member 350 is further advanced from the state of FIG. In the same figure, since the retaining piece 340 is connected to the protective member 350 at the rail groove 343a, the retaining piece 340 tends to proceed to the back together with the protective member 350. However, the sliding contact portion 34
Since 0c hits the back wall surface 312b of the box portion 312, the retaining piece 340 cannot travel further back. Therefore, the retaining piece 340 moves relative to the protective member 350 toward the front side while sliding the guide wall 350f and the rail groove 343a.

At this time, since the guide wall 350f and the rail groove 343a are inclined with respect to the traveling direction of the protective member 350, the retaining piece 340 can be slid inward simultaneously. At that time, since the sliding contact portion 340c is always pressed against the inner wall surface 312b of the box portion 312, the retaining piece 340 can be stably slid inward. When the retaining piece 340 slides inward by a predetermined amount, the sliding contact portion 340c is moved to the holding column 312c and the inner wall surface 312b of the box portion 312.
Therefore, it is possible to slide more stably. Further, the sliding contact portion 340c is provided on the rear wall surface 3 of the holding column 312c and the box portion 312.
12b, it will be impossible to move the retaining piece 340 straight forward to the front side.

When the protective member 350 advances until it hits the inner wall 312b of the box portion 312, the retaining piece 340 proceeds inward until the retaining plate 341a contacts the holding column 312c. At this position, the retaining portion 341 formed on the retaining piece 340 can be engaged with the engaging portion 323 that proceeds from the front side. That is, it can be said that the retaining piece 340 is in the first mounted state by sliding the retaining piece 340 to the position of FIG. FIG. 29 shows a state in which the engaging portion 323 is engaged with the retaining portion 341. When the engaging portion 323 engages with the retaining portion 341, a load is applied so that the retaining plate 341a bends outward, but the retaining wall 341a bends outward because the guide wall 350f enters the rail groove 343a. The original shape can be maintained.

In this case, the guide wall 350f and the rail groove 343a may slip and the protective member 350 may move forward, but the inclination angle of the guide wall 350f and the rail groove 343a is an acute angle with respect to the side plate 350a. Therefore, most of the load for bending the retaining plate 341a outward can be converted into the frictional resistance at the contact portion between the guide wall 350f and the rail groove 343a. Therefore, the protective member 350 can be prevented from moving forward. Further, since the temporary fixing portions 322d and 322d abut against the protective member 350 from the front side when the predetermined amount of the engaging portion 323 has advanced, the protective member 350 does not move forward.

On the other hand, when the temporary fixing portions 322d and 322d are removed by destroying a connecting portion (not shown), the protective member 350 can be pulled out to the near side. At this time, the retaining member 340 connected to the protective member 350 together with the protective member 350 traveling toward the near side also tends to move toward the near side. However, since the sliding contact portion 340c comes into contact with the holding column 312c from the back, the retaining piece 340 cannot advance straight forward. Therefore, the retaining piece 3
40 slides outward in the width direction while sliding the guide wall 350f and the rail groove 343a. When the predetermined amount of the retaining piece 340 slides outward in the width direction, the engaging portion 3
23 and the retaining portion 341 are disengaged, and interference between the sliding contact portion 340c and the holding column 312c is also released.

Therefore, after that, the retaining piece 340 can be pulled out to the near side. Furthermore, since the guide wall 350f of the protective member 350 enters the rail groove 343a of the retaining piece 340,
By removing the protective member 350 to the near side, the retaining piece 340 can also be removed. Since the guide wall 350f and the side plate 350a are joined at the tip of the back, the rail groove 3
The guide wall 350f is not removed from 43a, and the retaining piece 340 and the protection member 350 are not separated. Accordingly, by removing the protective member 350 to the front side, the retaining piece 3 is securely removed.
40 can be extracted. In this manner, the extracted retaining piece 340 and the protective member 35 are removed.
0 can be used for the next engagement. Accordingly, the preliminary retaining piece 340 and the protective member 350
It is possible to realize resource saving.

(7) Summary:
As described above, in the gaming machine according to the present invention, the retaining portion is formed in the box portion waiting for the insertion of the engaging portion, and the first state in which the retaining portion can be engaged with the engaging portion and the engaging portion. It is possible to switch to the second state that does not match. By doing in this way, it becomes possible to selectively set the box part to be engaged among a plurality of box parts. Moreover, since it is not necessary to remove the retaining portion that is not engaged from the box portion, the space for retaining the removed retaining portion can be omitted from the control box, and management is performed so that the retaining portion is not lost. There is no need.
