Description

  The present invention relates to a board case that houses therein a board on which an electronic circuit or the like for controlling a gaming operation in a gaming machine such as a slot machine or a pachinko machine is formed.

Conventionally, a gaming machine such as a slot machine or a pachinko machine includes a control board provided with an electronic circuit including a semiconductor element such as a CPU or ROM in order to control a gaming operation related to the progress of the game. Yes. Such a substrate is generally stored inside a transparent synthetic resin substrate case formed in a box shape so that it cannot be replaced with a substrate that has been illegally processed or modified. It is attached inside the chassis of the gaming machine.
A board housed in the board case and a board housed in another board case are electrically connected via a harness. This harness is generally composed of cable-side connectors provided at both ends and a cable connecting them. Each of these cable side connectors is connected to a board side connector provided on a different board. In gaming machines installed in game halls, a so-called hanging goto may be performed in which a harness that connects different boards is removed and an unauthorized part is replaced with a harness that is connected midway. Further, when the cable-side connector is inserted into and removed from the board-side connector, an illegal act may be performed in which the stored contents of the memory are illegally reset. In order to prevent the occurrence of these illegal acts, the cable-side connector cannot be pulled out of the board-side connector when the board-side connector and the cable-side connector are stored inside the board case and the board case is sealed. (For example, Patent Document 1).

However, in the conventional board case, foreign objects such as wires are inserted into the inside from the opening for the other end of the cable, one end of which is connected to the board side connector inside, to the outside of the board case. There is a problem that it is easy to be performed.
In view of the above-mentioned problems, the invention according to claim 1 of the present application is designed to prevent multiple arrivals to the board-side connector even if foreign matter such as a wire is inserted from the opening for taking out the cable. It is an object of the present invention to provide a board case that is difficult to reach the side connector, easily prevents unauthorized access, and that does not damage components and wiring on the board by the cable.
In addition to the object of the first aspect of the present invention, a second object of the present invention is to provide a board case in which the cable-side connector is unlikely to come off from the board-side connector even when an external cable is pulled. .

In addition to the object of the invention described in claim 2, the invention described in claim 3 provides a board case that can bend the cable without difficulty, prevent disconnection of the cable, etc., and prevent fraud. The purpose is to provide.
In addition to the object of the invention described in claim 3, an object of the invention described in claim 4 is to provide a substrate case that can bend the cable without difficulty and prevent disconnection and the like.

  In addition to the object of the invention described in any one of the first to fourth aspects, the invention described in claim 5 moves within a wide movable range even if the cable that is externally moved is moved. It is an object of the present invention to provide a substrate case that can be handled without any problem by suppressing the stress, suppresses concentration of stress on a part of the cable, and can reduce breakage or disconnection of the cable.

(Claim 1)
The substrate case 100 according to the first aspect of the present invention is a substrate case 100 that houses therein a substrate 90 to which one end of a cable 110 that is electrically connected to the outside is connected. Has a board-side connector 130, and the cable 110 is provided with a cable-side connector 120 at both ends, and the cable-side connector 120 at one end thereof is connected to the board-side connector 130. The other end of the cable 110 protrudes to the outside of the substrate case 100. The substrate case 100 includes a case main body member 150 and a case cover member 160 that cover the substrate 90 from the front and the back, and the case cover member 160 is provided with an opening 140 for guiding the other end of the cable 110 from the cable-side connector 120 connected to the board-side connector 130 to the outside of the board case 100. The above The board-side connector 130 is formed at a different position in plan view, and the opening 140 is formed on a surface of the case lid member 160 facing the board 90, and the opening 140 and the board-side connector The cable 110 from the cable-side connector 120 that protrudes from the case lid member 160 toward the board 90 and is connected to the board-side connector 130 can be inserted into the opening 140 side. Two inner walls 170 are provided, and the two inner walls 170 are between the connector-side inner wall 172 positioned between the board-side connector 130 and the opening 140, and between the connector-side inner wall 172 and the opening 140. And an opening-side inner wall 171 that protrudes from the edge of the opening 140 toward the substrate 90, and between the substrate-side connector 130 and the opening 140 on the surface of the substrate 90. , Parts and wiring A non-circuit region 94 in which no deviation is arranged is provided.

Here, the above-mentioned “plan view” means that the substrate case 100 is viewed from the case lid member 160 side. Specifically, for example, when the case lid member 160 of the substrate case 100 is placed on a horizontal plane so as to face the upper surface, the positional relationship is viewed from directly above the case lid member 160. That is, it means that the opening 140 and the board-side connector 130 are formed so as not to overlap when the board case 100 is viewed from the case lid member 160 side.
According to the present invention, even if a foreign substance such as a wire is inserted into the board case 100 from the opening 140, the connector-side inner wall 172 and the opening-side inner wall 171 are likely to block the entry of the wire or the like. This makes it difficult for foreign matter inserted from the opening 140 to reach the board-side connector 130.
In the present invention, the presence of the opening-side inner wall 171 can prevent multiple foreign objects such as wires inserted from the opening 140 from reaching the board-side connector 130 as compared with the case of the connector-side inner wall 172 alone. .

In addition, one end of the cable 110 is already connected to the substrate 90 inside the substrate case 100 from the beginning. For this reason, wiring work when installing the gaming machine 10 using the board case 100 in the game hall is facilitated by the amount of time and labor required for connecting with a connector or the like.
In the present invention, since the cable 110 is close to the surface of the substrate 90 and easily comes into contact with the surface of the substrate 90, the surface of the substrate 90 facing between the substrate-side connector 130 and the opening 140 is A non-circuit region 94 in which neither components nor wiring is arranged is used.

In the present invention, a non-circuit region 94 is provided between the board-side connector and the opening. For this reason, even if a foreign object such as a wire is inserted from the opening 140, neither the component nor the wiring is arranged on the surface of the substrate 90 at the inserted portion. This makes it easier to prevent unauthorized operations such as direct damage or short-circuiting on components and wiring.
Furthermore, since the cable 110 cannot come into contact with components and wiring at least in the portion from the opening 140 to the board-side connector 130, the cable 110 does not damage the components and wiring in this portion.

The wiring between the board-side connector 130 and the part that processes the data input from the board-side connector 130 is formed on a part other than the surface of the board 90 on which the board-side connector 130 is provided. You may do it. Specifically, the wiring between the board-side connector 130 and the part that processes the data input from the board-side connector 130 is a part other than the surface of the board 90 where the board-side connector 130 is provided, For example, it can be provided on the back surface of the substrate 90. Alternatively, when the substrate 90 has a multilayer structure, such wiring may be provided below the second layer. This makes it difficult or impossible to access such wiring directly from the opening 140, and prevents illegal acts such as obtaining or tampering with data input from the board-side connector 130. It becomes easy to do.
(Claim 2)
The invention described in claim 2 is characterized by the following points in addition to the features of the invention described in claim 1 described above. That is, the leading edge 173 of the opening-side inner wall 171 is positioned on the board 90 side with respect to the virtual straight line that is the shortest distance from the cable-side connector 120 connected to the board-side connector 130 to the opening 140. It is characterized by being formed.

Here, the “virtual straight line” is an opening from the cable-side connector 120 when it is assumed that there is no obstacle between the cable-side connector 120 connected to the board-side connector 130 and the opening 140. It can be grasped as a cable 110 that stretches up to the portion 140 without slack.
If the leading edge 173 of the opening-side inner wall 171 is formed closer to the case lid member 160 than the virtual straight line, and the cable 110 extending from the opening 140 to the outside is pulled from the outside, the cable 110 Accordingly, the pulling force is directly applied to the cable-side connector 120 connected to the board-side connector 130. In such a case, the cable side connector 120 may be easily pulled out from the board side connector 130.

Therefore, in the present invention, the leading edge 173 of the opening-side inner wall 171 extends beyond the imaginary straight line to the substrate 90 side.
That is, by having the opening-side inner wall 171 having such a shape, the cable 110 from the cable-side connector 120 connected to the board-side connector 130 is linearly formed so as to have the shortest distance to the opening 140. It cannot be arranged, and it is necessary to bypass the tip edge 173 of the opening-side inner wall 171. For this reason, when the cable 110 drawn out from the opening 140 is pulled in the axial direction drawn out toward the outside, the cable 110 comes into contact with the tip edge 173 of the opening-side inner wall 171 and bends. In such a case, the cable 110 is hooked on the leading edge 173 of the opening side inner wall 171 by the frictional force between the leading edge 173 of the opening side inner wall 171 and the surface of the cable 110. As a result, it is possible to suppress the force that is pulled from the outside via the cable 110 from being directly applied to the connection portion of the cable 110. Even if the force is applied, the magnitude of the force finally applied to the connection portion is reduced by the frictional force with the leading edge 173 in the middle.

Thereby, it is possible to suppress external force from being directly applied to the cable-side connector 120, and the possibility of occurrence of a situation such as disconnection due to an unauthorized operation from the outside is reduced.
In addition, in order to increase the frictional force between the leading edge 173 of the opening side inner wall 171 and the surface of the cable 110, the contact area between the two is increased more than the case lid member 160 side of the opening side inner wall 171. A shape that increases the thickness of the opening-side inner wall 171 on the tip edge 173 side (for example, the opening-side inner wall 171 has a trapezoidal cross-sectional shape, and the thickness on the substrate 90 side is larger than the thickness on the case lid member 160 side) May be formed).

(Claim 3)
The invention described in claim 3 has the following features in addition to the features of the invention described in claim 2 described above. That is, the connector side inner wall 172 is provided with a notch 190 for inserting the cable 110 from the cable side connector 120 connected to the board side connector 130 to the opening 140 side. Features.
If the notch 190 is not formed, the cable 110 extending from the board-side connector 130 needs to bypass and bend the wall portion of the connector-side inner wall 172. If the cable 110 is bent in such a manner, bending stress is applied to the cable 110, which may cause disconnection or the like. Therefore, the connector-side inner wall 172 close to the board-side connector 130 does not block the portion where the cable 110 passes along a gentle curve. Thereby, the cable 110 is bent without difficulty, and disconnection of the cable 110 is prevented.

The cable 110 from the board-side connector 130 passes through the opening 140 via the notch 190 of the connector-side inner wall 172, is taken out of the board case 100, and reaches the other end. Even if a person who attempts an unauthorized operation attempts to insert a foreign object from the opening 140 and reach the board-side connector 130 through the notch 190, the cable 110 exists in the notch 190. For this reason, the foreign matter is unlikely to pass through the notch 190.
As a result, even if a foreign object such as a wire is inserted from the opening 140, it is possible to make it difficult to reach the board-side connector 130. Thereby, it is possible to easily prevent fraud.

  The width dimension of the notch 190 according to the present invention is not particularly limited as long as it is a width that the cable 110 can pass through, but is desirably a minimum width within the range of such a width. By doing so, at least a foreign object having a diameter larger than the diameter of the cable 110 cannot pass through the notch 190, and unauthorized access to the board-side connector 130 can be more firmly prevented. Further, when the cable 110 with the tubular or cylindrical protective cover is used, the width dimension of the notch 190 is formed to a minimum width that can pass the width dimension including the dimension of the protective cover. It is desirable that

(Claim 4)
The invention described in claim 4 has the following features in addition to the features of the invention described in claim 3 described above. That is, a gap 180 through which the cable 110 can be passed is formed between the leading edge 173 of the opening-side inner wall 171 and the surface of the substrate 90, and the opening 180 from the leading edge 173 of the opening-side inner wall 171 in the gap 180 The distance to the surface of the substrate 90 is shorter than the distance in which the cutout portion 190 is cut out in the vertical direction from the surface of the substrate 90, and from the tip edge 173 other than the cutout portion 190 of the connector side inner wall 172. It is characterized by being formed so as to be longer than the distance to the surface of the substrate 90.

According to the present invention, since the gap 180 is provided in the opening-side inner wall 171, the cable 110 can pass through a shorter route without bypassing the opening-side inner wall 171. Further, foreign objects larger than the shape of the gap 180 can be prevented from passing through.
Here, if the gap 180, which can be a foreign substance intrusion path, is formed at a shallow position near the edge of the opening 140, foreign substances such as wires are easily inserted. Therefore, in the present invention, the gap 180 is formed on the surface side of the substrate 90, that is, at a position far from the edge of the opening 140, so that it is more difficult to insert a foreign object and to perform the operation. .

  Furthermore, according to the present invention, the opening-side inner wall 171 hides a part of the notch 190 as viewed from the opening 140 side. In other words, the opening-side inner wall 171 is closer to the opening 140 than the connector-side inner wall 172, and blocks a part of the notch 190 where foreign matter may enter. As a result, the opening-side inner wall 171 prevents a foreign substance from entering from the opening-side inner wall 171 while securing a space through which the cable 110 passes as a gap 180.

  Here, the notch 190 is formed in the connector-side inner wall 172 in order to secure a portion through which the cable 110 passes. Specifically, the connector side inner wall 172 is formed at a position closer to the board side connector 130 than the opening side inner wall 171. For this reason, if the height of the notch 190 is too low, the cable 110 from the board-side connector 130 needs to be bent sharply. If the cable 110 is bent in such a manner, bending stress is applied to the cable 110, which may cause disconnection or the like. Therefore, in order to make the bending of the cable 110 extending from the board-side connector 130 as gentle as possible, the distance of the notch 190 cut away from the surface of the board 90 in the vertical direction is from the front edge 173 of the gap 180 to the surface of the board 90. It is formed to be longer than the distance up to. As a result, the cable 110 extending from the board-side connector 110 is guided to the gap 180 of the opening-side inner wall 171 while being bent without difficulty.

  The width of the notch 190 (slit width (P)) of the connector-side inner wall 172 may be formed to a minimum width that the cable 110 can pass through. Specifically, the width (R) of the gap 180 is preferably less than about 3 times the diameter of the cable 110. When formed in this way, when the cable 110 that is exposed to the outside from the opening 140 is moved from the outside, the cable 110 extending from the board-side connector 130 remains sandwiched and fixed by the notch 190. In this state, only the portion of the cable 110 ahead (external side) of the connector-side inner wall 172 can move. Accordingly, the movement of the cable 110 located from the connector-side inner wall 172 to the board-side connector 130 is suppressed, and the connection portion between the board-side connector 110 and the cable 110 is less likely to be interfered with the movement from the outside.

  In addition, a square cylindrical wall extending from the back surface of the case lid member 160 toward the substrate 90 may be formed around the opening 140. Thereby, it is possible to prevent foreign matter from being inserted into the substrate case 100 from the opening 140. A part of the wall around the opening 140 can be used as the opening-side inner wall 171. Further, the wall extending from the edge of the opening 140 toward the surface of the substrate 90 may have a tapered cylindrical shape. Thereby, it can be made more difficult to insert a foreign object from the outside of the opening 140.

(Claim 5)
The invention described in claim 5 has the following features in addition to the features of the invention described in claim 4. That is, the width of the gap 180 in the opening-side inner wall 171 in the direction parallel to the substrate 90 is formed to be wider than the width of the notch 190 in the direction parallel to the substrate 90. .

  According to the present invention, even if the cable 110 that has exited the sub-board case 102 from the opening 140 is moved, the cable 110 moves in a direction parallel to the surface of the sub-board 92 along the leading edge 173 of the opening-side inner wall 171. On the other hand, since the cable 110 is moved in a wide movable range, it can be handled without any trouble. As a result, it is possible to suppress the concentration of stress on a part of the cable 110 with respect to the movement of the cable 110, and to reduce the breakage or disconnection of the cable 110.

Since this invention is comprised as mentioned above, there exists an effect as described below.
According to the invention of claim 1, even if a foreign substance such as a wire is inserted from the opening for taking out the cable, it is difficult to reach the board side connector by preventing multiple arrivals to the board side connector, It is possible to provide a substrate case that can easily prevent unauthorized access.
Furthermore, according to the first aspect of the present invention, it is possible to provide a board case in which components and wiring on the board are not damaged by the cable from the board-side connector to the opening.
According to the invention described in claim 2, in addition to the effect of the invention described in claim 1, it is possible to provide a board case in which the cable-side connector is unlikely to come off from the board-side connector even when an external cable is pulled.

According to the invention described in claim 3, in addition to the effect of the invention described in claim 2, the board case can bend the cable without difficulty, can prevent the cable from being disconnected, and can easily prevent fraud. Can be provided.
According to the invention described in claim 4, in addition to the effect of the invention described in claim 3, it is possible to provide a board case that can bend the cable without difficulty and prevent disconnection and the like.
According to the fifth aspect of the invention, in addition to the effect of the fourth aspect of the invention, even if the cable that has been externally moved is moved, the cable can be moved within a wide movable range without any trouble. Thus, it is possible to provide a board case that can suppress stress concentration on a part of the cable and reduce breakage or disconnection of the cable.

The plurality of covered electric wires 112 are covered with a tubular cover 111 (see FIG. 13) made of a transparent resin having flexibility. In the present embodiment, the cable 110 is a cable whose outer periphery is covered with a tubular cover 111. However, the cable 110 is not necessarily limited to this, and the cable 110 is tubular. It may be formed only by the covered electric wire 112 without being covered with the cover 111. Here, the diameter of the cable 110 means the inner diameter of a circle in the cross section of the virtual cylinder such that the four covered electric wires 112 are bundled into one. The tubular cover 111 can be easily deformed with a soft resin, and the outer diameter of the cable 110 and the outer diameter of the cable 110 covered with the tubular cover 111 are formed to be approximately the same. Yes.

The cable side connector 120 includes a main cable side connector 121 provided at one end of the cable 110 and a sub cable side connector 122 provided at the other end of the cable 110. The main cable side connector 121 is formed so as to be connectable to the main board side connector 131 of the main board 91, and the sub cable side connector 122 is formed so as to be connectable to the sub board side connector 132 of the sub board 92.
The main cable side connector 121 and the sub cable side connector 122 are formed in different shapes. Specifically, the sub cable-side connector 122 is formed in a shape that can be inserted through the opening 140. The main cable side connector 121 is formed in a shape that cannot be inserted through the opening 140.

The connectors (the main cable side connector 121 and the sub cable side connector 122) are similar to each other, but may be formed to have different dimensions. For example, the shapes may be similar to each other, and only one dimension may be different so that one connector cannot be inserted through the opening 140 and the other connector can be inserted.
(Opening 140)
The opening 140 guides the other end of the cable 110 from the sub cable side connector 122 connected to the sub board side connector 132 to the outside of the sub board case 102 as shown in FIGS.

The opening 140 and the sub-board-side connector 132 are formed at different positions in plan view as viewed from the case lid member 160 (see FIG. 10). Specifically, the opening 140 is formed closer to the center of the case lid member 160 than the position of the case lid member 160 facing the sub-board-side connector 132 (see FIG. 8).

Further, the opening is formed in a size and shape that allows the cable 110 covered with the tubular cover 111 to be inserted.
(Inner wall 170)
As shown in FIGS. 5, 8, 9, and 11, between the opening 140 and the sub-board-side connector 132, the case 140 projects from the case lid member 160 toward the sub-board 92, and the opening 140 And an inner wall 170 for separating the sub board-side connector 132 from each other. The inner wall 170 includes two openings, an opening-side inner wall 171 provided on the opening 140 side and a connector-side inner wall 172 provided on the sub-board-side connector 132 side.

The connector-side inner wall 172 is positioned between the opening 140 and the board-side connector 130 (more specifically, between the opening-side inner wall 171 and the board-side connector 130), This is for projecting toward the board 92 and for separating the opening 140 and the board-side connector 130 (more specifically, between the opening-side inner wall 171 and the board-side connector 130).
The connector side inner wall 172 is formed adjacent to the vicinity of the sub board side connector 132. The sub-board-side connector 132 is formed so as to stand vertically from the surface of the sub-board 92, and the connector-side inner wall 172 is formed in parallel with the standing direction of the sub-board-side connector 132. .

In the connector side inner wall 172, the cable 110 from the sub cable side connector 122 connected to the sub board side connector 132 is connected to the side on which the opening 140 is arranged from the side on which the sub board side connector 132 is arranged. A notch 190 is provided for insertion toward the end.
The opening-side inner wall 171 is located between the connector-side inner wall 172 and the opening 140, protrudes from the case lid member 160 toward the sub-board 92, and separates the connector-side inner wall 172 and the opening 140 from each other. Is for. A gap 180 through which the cable 110 can be passed is formed between the leading edge 173 of the opening-side inner wall 171 and the surface of the sub-board 92.
The opening-side inner wall 171 is formed such that the leading edge 173 is located on the sub-board 92 side of the virtual straight line that is the shortest distance from the sub-cable-side connector 122 to the opening 140.

  As shown in FIG. 5, the case lid member 160 is formed such that a square frame 169 protrudes from the periphery of the opening 140 of the case lid member 160 toward the sub-board 92 side. The opening-side inner wall 171 forms a surface of the square frame 169 on the front side of the opening 140 (sub-board-side connector 132 side). The square frame 169 has an upper wall 174 that forms an upper surface of the square frame 169 and a lower wall 175 that forms a lower surface of the square frame 169 when the sub-board case 102 is fixed to the side plate 11b. And a back wall 176 that forms a back surface of the square frame 169. That is, the rectangular frame 169 is formed in a rectangular frame shape that protrudes from the opening 140 toward the sub-board 92 side by the opening-side inner wall 171, the upper wall 174, the inner wall 176, and the lower wall 175.

In the present embodiment, the connector-side inner wall 172 and the opening-side inner wall 171 are formed as the inner wall 170. However, the present invention is not limited to this, and the connector-side inner wall 172, Only one of the side inner walls 171 may be formed. Further, another inner wall may be added between the opening 140 and the sub-board-side connector 132 to form three or more inner walls. At that time, a cutout 190 or a gap 180 through which the cable 110 can be inserted is formed in the added inner wall 170.
(Notch 190)
The notch 190 is formed in the connector-side inner wall 172 so that the cable 110 from the sub-cable-side connector 122 connected to the sub-board-side connector 132 is inserted toward the opening 140 side. As shown in FIG. 9E, which is a cross section B of FIG. 9B, the notch 190 is cut out from the sub-board 92 side of the connector-side inner wall 172 toward the case lid member 160. It is. By forming the notch 190, a slit 191 that is an open hole through which the cable 110 can be inserted is formed between the notch 190 and the surface of the sub-board 92. The slit 191 is a substantially rectangular open hole (cable 110) having a slit distance Q from the surface of the sub-board 92 to the edge of the notch 190 in the vertical direction and a slit width P in the direction perpendicular to the slit distance Q. Is an insertion hole through which can be inserted. The dimension of the slit width P of the notch 190 is formed to a minimum width through which the cable 110 covered with the tubular cover 111 can pass. Specifically, the dimension of the slit width P is the diameter of the cable 110 (here, the slit width P is tubular when using the cable 110 covered with the tubular cover 111 as in this embodiment. The diameter of the cover 111 is the diameter of the cable 110 when using the cable 110 that is not covered by the tubular cover 111. Here, the diameter of the cable 110 passes through a bundle of four covered electric wires 112. It is set to the same size as the minimum width to obtain. Of course, the present invention is not limited to this, and may be set to be slightly shorter than the diameter of the cable 110 in consideration of the elastic deformation of the cable 110, and the workability of ease of insertion is considered. Then, it may be set longer than the diameter of the cable 110.

In addition, as shown in FIG. 11, the notch 190 allows the cable 110 to be easily inserted into the notch 190 when the sub cable-side connector 122 is connected to the sub board-side connector 132. It is formed to be longer than the distance V from the surface of the substrate 92 to the surface of the sub cable side connector 122 on the case lid member 160 side (see FIG. 9D, which is a cross section A of FIG. 9A). Note that the cable 110 is omitted in FIG.
(Gap 180)
As shown in FIG. 11, a gap 180 through which the cable 110 can pass is provided between the leading edge 173 of the opening-side inner wall 171 and the surface of the sub-board 92. The gap 180 is formed in the opening-side inner wall 171 as shown in FIG. 9 (f), which is a cross section C of FIG. 9 (c), and extends from the surface of the sub-substrate 92 to the opening-side inner wall 171. This is a rectangular open hole (an insertion hole through which the cable 110 can be inserted) composed of a gap distance S to the leading edge 173 and a gap width R in a direction perpendicular to the gap distance S. As shown in FIG. 11, the gap distance S is set to a sufficient distance so that the cable 110 can be inserted between the leading edge 173 and the surface of the sub-board 92.

The gap distance S is formed so as to be shorter (S <Q) than the slit distance Q of the notch 190 of the connector side inner wall 172 as shown in FIGS. 9 (e) and 9 (f) and FIG. ing.
As shown in FIGS. 9E and 9F, the gap width R is formed to be longer (P <R) than the slit width P of the notch 190 of the connector-side inner wall 172.
The gap distance S may be set to be slightly shorter than the outer diameter of the cable 110 (or the outer diameter of the tubular cover 111) in consideration of elastic deformation of the cable 110. In consideration of this workability, it may be set slightly longer than the outer diameter.
When the cable 110 does not have the tubular cover 111, the gap distance S may be formed to be a minimum distance through which the bundle of four covered electric wires 112 that are not covered with the tubular cover 111 can pass. Good.

The gap width R is formed to be the same as the opening width opening in the direction of the gap width R of the opening 140.
Note that the gap width R of the opening-side inner wall 171 may be formed to be smaller than the opening width of the opening 140. As a result, the movement in the width direction of the cable 110 is gradually reduced at three locations of the width of the opening 140, the gap width R, and the slit width P from the outside to the inside of the substrate case 100. Limited. That is, the distance (displacement amount) by which the cable 110 is moved in the width direction from the outside by the opening 140, the gap 180 of the opening side inner wall 171 and the notch 190 of the connector side inner wall 172 is from the opening 140. The gap 180 of the opening side inner wall 171 decreases from the gap 180 to the notch 190 in a stepwise manner. In this way, the substrate case 100 can be provided with a kind of buffer function that can reduce the amount of displacement of the cable 110 due to an external operation in a stepwise manner. Therefore, it is possible to further suppress the stress from being concentrated in the middle of the cable 110 or in one specific place such as the connection portion. As a result, the breakage and damage of the connecting part, which is usually the most easily broken and easily damaged part, can be further suppressed.

Conversely, the gap width R of the opening-side inner wall 171 may be formed to be larger than the opening width of the opening 140. Thus, even when the cable 110 is swung up to the opening width of the opening 140 and moved, the cable 110 does not collide with the end of the gap 180 of the opening-side inner wall 171. Damage is avoided.
(Visual confirmation unit 161)
As shown in FIG. 10, the case lid member 160 is formed with a visual confirmation portion 161 made of a transparent member in a region substantially opposite to the sub-board-side connector 132 of the sub-board 92. This visual confirmation part 161 is a portion made of a flat transparent resin having the same thickness and having no protrusions or steps, and the visibility of the periphery of the sub board side connector 132 from the outside of the sub board case 102 is good. It is what you are trying to do. In particular, the connection portion of the sub cable side connector 122 connected to the sub board side connector 132 is easy to see from the outside.

In the present embodiment, not only the visual confirmation part 161 but also the entire case lid member 160 is formed of a transparent resin made of a transparent member. As a result, it is possible to detect an illegal act at an early stage, and in addition, the cable side connector 120 is disconnected from the board side connector 130, or an abnormal location such as disconnection due to a problem such as part dropping or twisting in the middle of the cable 110, etc. Is easy to discover.
(Locking part 220)
As shown in FIGS. 4 and 7, the sub-board case 102 is provided with a locking portion 220 for hooking the cable 110 that has passed from the opening 140 to the outside of the sub-board case 102. The locking portion 220 is formed so that the cable 110 can be locked.

Here, the length of the cable 110 is long enough to allow the cable 110 to be locked from the opening 140 to the locking portion 220 and then be folded back from the locking portion 220 and temporarily fixed by the temporary fixing portion 200. It is formed to become.
As shown in FIG. 12, the engaging part 220 is continuous with the outer surface of the substrate case 100 from a part of the concave part 230 and a concave part 230 recessed from the outer surface at the edge part of the sub-board case 102. And a protruding piece 240 that protrudes. The protruding piece 240 is formed to be elastically deformable when the cable 110 is locked. As shown in FIG. 13, when the cable 110 is locked, a hole 232 is formed in the bottom surface 231 of the recess 230 so as to allow a part of the cable 110 to escape. Then, when the cable 110 is inserted into the recess 230 in a state where the cable 110 is hooked on the projecting piece 240, a part of the cable 110 is pushed toward the inside of the hole 232 of the recess 230 by the projecting piece 240. It is formed to be.

  The protruding piece 240 has a tip bulging portion 241 that is bent in an L-shaped cross section toward the hole 232 side of the recess 230 at the tip portion. Further, a stepped portion 242 that is continuous with the outer surface of the sub-board case 102 and has a stepped side edge is formed on the base end side of the protruding piece 240. In order to prevent the cable 110 locked to the protruding piece 240 from being sandwiched between the step portion 242 and the tip bulging portion 241, the distance between the step portion 242 and the tip bulging portion 241 is The diameter of the cable 110 (specifically, when the cable 110 covered with the tubular cover 111 is used as in the present embodiment, the diameter of the cable 110 becomes the diameter of the tubular cover 111. When used, the diameter is the same as that of the cable 110. The same applies hereinafter). Of course, the distance between the step portion 242 and the tip bulging portion 241 is not limited to this, and is set to be slightly shorter than the diameter of the cable 110 in consideration of the elastic deformation of the cable 110. Alternatively, the cable 110 may be set to be longer than the diameter of the cable 110 in consideration of workability of ease of locking.

(Temporary fixing part 200)
As shown in FIGS. 7 and 14, the main cable side connector 121 provided at the end portion of the cable 110 extending outside from the opening 140 is temporarily fixed to the case lid member 160 of the sub-board case 102. For this purpose, a temporary fixing part 200 to be engaged is provided. When the sub-board case 102 is fixed to the side plate 11b of the housing 11, the main cable-side connector 121 is pulled out from the temporary fixing portion 200 and is attached to the back plate 11d of the housing 11 as shown in FIG. It is connected to a main board side connector 131 provided on the main board 91 of the main board case 101 arranged.
The temporary fixing portion 200 is formed on a surface of the outer peripheral surface of the sub substrate case 102 that is perpendicular to the front and back surfaces of the sub substrate case 102 housed in the sub substrate case 102. Specifically, as shown in FIGS. 14 and 15, the temporary fixing portion 200 is formed on the front surface when the sub substrate case 102 is fixed to the left side plate 11 b of the housing 11. Further, the temporary fixing portion 200 is open in a direction perpendicular to the front and back surfaces of the sub-board case 102 housed in the sub-board case 102. Specifically, as shown in FIGS. 14 and 15, when the sub-board case 102 is fixed to the left side plate 11b of the housing 11, the temporary fixing portion 200 is changed from the left side plate 11b to the right side plate 11b. Open toward. And this temporary fix | stop part 200 is formed in the substantially bowl shape in the whole shape. Therefore, the temporary fixing portion 200 is temporarily fixed when the leading end of the main cable side connector 121 is inserted in the vertical direction with respect to the front and back surfaces of the sub-board 92 as shown in FIG. In addition, as shown in FIG. 17, the main cable side connector 121 is pulled out from the temporary fixing portion 200 by pulling the main cable side connector 121 from the temporary fixing portion 200 in a direction perpendicular to the front and back surfaces of the sub-board 92. It is removed and the temporarily fixed state is eliminated.

The distance from the locking portion 220 to the temporary fixing portion 200 is formed to be longer than the distance from the locking portion 220 to the main board side connector 131 when the sub board case 102 is fixed.
(Actions and effects mainly related to fraud countermeasures by the inner wall 170, etc.)
According to the present embodiment, as shown in FIG. 10, the opening 140 and the sub board side connector 132 are formed at different positions in plan view. An inner wall 170 (opening side inner wall) that protrudes from the case lid member 160 toward the sub board 92 and separates the opening 140 and the board side connector 130 between the opening 140 and the sub board side connector 132. 171 and the connector side inner wall 172) are provided. For this reason, even if a foreign substance such as a wire is inserted into the sub-board case 102 from the opening 140, the inner wall 170 is more likely to block the entry of the wire or the like. Thereby, the possibility that the foreign matter inserted from the opening 140 reaches the sub-board-side connector 132 is reduced.

  On the other hand, the connector-side inner wall 172 is provided with a notch 190 for allowing the cable 110 to pass therethrough. Specifically, as shown in FIG. 11, the sub cable side connector 122 at one end of the cable 110 is inserted from the opening 140 and connected to the sub board side connector 132 in the sub board case 102. . At this time, the cable 110 extending from the sub-cable-side connector 122 is in a state of being led out from the opening 140 through the notch 190 of the connector-side inner wall 172 and the gap 180 of the opening-side inner wall 171. Thereafter, even if a person trying to perform an unauthorized operation tries to reach the sub-board-side connector 132 through the gap 180 or the notch 190 with the foreign matter inserted through the opening 140, the gap 180 or the notch 190 Since the cable 110 is present inside, the possibility that a foreign object can be inserted through the notch 190 is reduced.

In addition, since the inner wall 170 is formed, when the inner wall 170 is destroyed by an illegal act from the opening 140 to the sub-board-side connector 132, the trace remains. For this reason, the detection of fraudulent behavior can be detected early in the visual sense.
As a result, there is a high possibility that a gotting action (unauthorized action) such as a so-called hanging goto will be prevented, and there is a high possibility that unauthorized access using the cable side connector 120 and the cable 110 will be prevented.
Further, if the cable 110 stays or meanders in the vicinity of the opening 140, the visual field near the opening 140 may be significantly blocked by the cable 110 in such a state. As shown in FIG. 10, the opening 140 and the sub board side connector 132 are located at different positions in plan view, so that the periphery of the sub board side connector 132 stays in the cable 110 passing through the opening 140. Thus, the visibility from the outside of the case lid member 160 is not significantly reduced, and good visibility is maintained.

  According to the present embodiment, the opening 140 and the sub board side connector 132 are separated by the inner wall 170 (the opening side inner wall 171 and the connector side inner wall 172). Specifically, as shown in FIG. 11, a connector-side inner wall 172 is provided adjacent to the sub-board-side connector 132, and an opening-side inner wall 171 is provided between the connector-side inner wall 172 and the opening 140. Yes. That is, a plurality of, specifically two, inner walls 170 are formed between the opening 140 and the sub board-side connector 132. For this reason, even when a wire or the like is inserted from the opening 140, the plurality of inner walls 170 can prevent the arrival at the sub-board-side connector 132 in multiple ways. Unauthorized access to the board-side connector 132 can be made more difficult.

Further, a gap 180 through which the cable 110 can pass is provided between the front end edge 173 of the opening side inner wall 171 and the surface of the sub-board 92, as shown in FIG. As a result, the cable 110 necessary for electrical connection with the outside can be passed around the opening-side inner wall 171 without detouring. Further, the insertion of foreign matter that does not enter the shape of the gap 180 is prevented. This increases the possibility that unauthorized access to the board-side connector 130 is prevented.
Further, as shown in FIG. 11, the gap 180 of the opening side inner wall 171 is formed between the leading edge 173 of the opening side inner wall 171 and the surface of the sub-substrate 92, that is, on the surface side of the sub-substrate 92. Here, if the gap 180 that can serve as a foreign material insertion path is formed at a shallow position near the outside of the opening 140, foreign matter such as a wire may be easily inserted. However, as in the present embodiment, the gap 180 is formed on the surface side of the sub-substrate 92, that is, at a position deep from the outside of the opening 140, so that the insertion of foreign objects such as wires and the operation can be further performed. It will be difficult. This increases the possibility of preventing unauthorized access.

According to the present embodiment, as shown in FIGS. 9 (e), 9 (f) and 11, the slit distance Q in the vertical direction from the surface of the sub-board 92 of the notch 190 is the leading edge of the opening-side inner wall 171. It is longer than the gap distance S of the gap 180 from 173 to the surface of the sub-board 92 (S <Q). Thereby, the opening-side inner wall 171 can block (hide) a part of the notched portion 190 of the connector-side inner wall 172 on the case lid member 160 side (a part of the slit 191).
The inner wall 171 on the opening side is closer to the opening 140 than the inner wall 172 on the connector side, and the space to be entered is reduced in order to prevent foreign objects from entering from the opening 140 first. It is. As a result, the opening-side inner wall 171 prevents an entry of foreign matter from the opening-side inner wall 171 to the sub-board-side connector 132 side while securing an opening hole through which the cable 110 is inserted by the gap 180.

  Further, as shown in FIGS. 9 (e), 9 (f) and 11, the slit distance Q is longer than the gap distance S so that the connector side inner wall 172 is notched so as to secure a portion through which the cable 110 passes. A portion 190 is formed. Specifically, the connector-side inner wall 172 is formed at a position closer to the sub-board-side connector 132 than the opening-side inner wall 171. Therefore, if the notch 190 as described above is not formed, the cable 110 extending from the sub-board-side connector 132 needs to bypass and bend the wall portion of the connector-side inner wall 172. If the cable 110 is bent in such a manner, bending stress is applied to the cable 110, which may cause disconnection or the like. Accordingly, the connector-side inner wall 172 close to the sub-board-side connector 132 prevents the cable 110 extending from the sub-board-side connector 132 from passing through a gentle curve. As a result, the cable 110 extending from the sub cable side connector 122 is bent without difficulty and guided to the gap 180 of the opening side inner wall 171. As a result, disconnection or the like of the cable 110 is prevented.

According to the present embodiment, since the dimension of the slit width P of the notch 190 of the connector-side inner wall 172 is set to the minimum width that the cable 110 covered with the tubular cover 111 can pass, the diameter of the cable 110 can be reduced. In addition, the notch 190 can prevent the insertion of a foreign substance having a large diameter. Thereby, unauthorized access to the sub-board-side connector 132 can be more securely prevented.
Here, similarly to the gap distance S, the gap width R of the opening-side inner wall 171 is the minimum width that the cable 110 can pass through, for example, the diameter of the cable 110 (specifically, the outer diameter of the tubular cover 111). To the same dimensions. In this way, the cable 110 is restrained in a narrow range of the gap 180, and when the cable 110 is moved from the outside, stress concentrates on a specific portion of the restrained cable 110, and the cable 110 is damaged or disconnected. Cause. Therefore, the gap width R of the opening-side inner wall 171 is longer than the slit width P of the notch 190 of the connector-side inner wall 172 (P <R), as shown in FIGS. Is formed. As a result, even if the cable 110 exiting the sub-board case 102 from the opening 140 is moved, the cable 110 moves in a direction parallel to the surface of the sub-board 92 along the tip edge 173 of the opening-side inner wall 171 (FIG. 9 ( With regard to f) from the front to the left and right, and in a direction perpendicular to the paper surface of FIG. 11, the cable 110 can be handled without any trouble by being moved within a wide movable range. As a result, it is possible to suppress the concentration of stress on a part of the cable 110 with respect to the movement of the cable 110, and to reduce the breakage or disconnection of the cable 110.

Here, it is assumed that the leading edge 173 of the opening-side inner wall 171 is formed closer to the case lid member 160 than the virtual straight line that is the shortest distance from the sub cable-side connector 122 to the opening 140. That is, the cable 110 is formed at the position of the virtual straight line. In such a case, when the cable 110 extending from the opening 140 to the outside is pulled in the axial direction, the force is applied to the connection portion of the cable 110 of the sub-cable-side connector 122. Join directly through 110. In such a case, the sub cable side connector 122 may be easily pulled out from the sub board side connector 132.
Therefore, according to the present embodiment, as shown in FIG. 11, the opening-side inner wall 171 has a tip edge 173 that is closer to the sub-board than the virtual straight line that is the shortest distance from the sub-board-side connector 132 to the opening 140. It is formed to be located on the 92 side. Due to the presence of the opening-side inner wall 171, the cable 110 from the sub-cable-side connector 122 connected to the sub-board-side connector 132 is arranged in a single straight line so as to have the shortest distance to the opening 140. In other words, they are arranged in a state of being bypassed by passing between the front end edge 173 of the opening-side inner wall 171 and the surface of the sub-board 92. For this reason, when the cable 110 taken out from the opening 140 is pulled in the axial direction drawn out from the outside, the cable 110 comes into contact with the tip edge 173 of the opening-side inner wall 171 and bends. In such a case, the cable 110 is caught on the leading edge 173 of the opening-side inner wall 171 by the frictional force between the leading edge 173 of the opening-side inner wall 171 and the surface of the cable 110. As a result, it is possible to suppress a force pulled from the outside directly via the cable 110 to the connection portion of the cable 110. Even if the force is applied, the magnitude of the force finally applied to the connection portion is reduced by the frictional force with the leading edge 173 in the middle. As a result, the force applied to the cable 110 from the outside is prevented from being directly applied to the sub-cable side connector 122, and the possibility of occurrence of a situation such as disconnection due to an unauthorized operation from the outside is reduced.

  In addition, in order to increase the frictional force between the leading edge 173 of the opening side inner wall 171 and the surface of the cable 110, the contact area between the two is increased more than the case lid member 160 side of the opening side inner wall 171. A shape that increases the thickness of the opening-side inner wall 171 on the tip edge 173 side (for example, a cross-sectional shape of the opening-side inner wall 171 is a trapezoid with a large thickness on the sub-board 92 side), or a tip of the opening-side inner wall 171 The surface near the edge 173 may be formed in a shape having a large number of minute protrusions for increasing the frictional resistance. In addition, a sheet member having a large surface friction coefficient such as a rubber sheet for increasing frictional resistance may be formed to be attached to the vicinity of the tip edge 173, and a material having the same effect is provided to the vicinity of the tip edge 173. It may be formed so as to be applied.

  According to the present embodiment, the width (slit width P) of the notch 190 of the connector-side inner wall 172 is formed to be substantially the same as the diameter of the cable 110, and is formed so that the cable 110 is sandwiched. As shown in FIG. 9 (f), the gap 180 of the opening-side inner wall 171 has a gap width R and a gap distance S so that the cable 110 can move. With this configuration, when the cable 110 that is exposed to the outside from the opening 140 is moved, the cable that extends from the sub-cable-side connector 122 connected to the sub-board-side connector 132 to the notch 190. The portion 110 is sandwiched between the notches 190 and remains fixed. On the other hand, the cable 110 portion ahead (external side) of the connector-side inner wall 172 is movable within a predetermined range under the influence of external force.

  At that time, as shown in FIG. 9 (f), the gap 180 in the opening-side inner wall 171 is a substantially rectangular open hole (an insertion hole represented by a gap distance S × a gap width R) along the surface of the sub-board 92. ). For this reason, the portion of the cable 110 close to the connection portion is fixed by the notch 190, and the cable 110 portion ahead (external side) of the connector-side inner wall 172 is the tip edge 173 of the gap 180 and the sub-board. It is possible to move between the surfaces of 92 along the width direction of the gap 180 (the left-right direction in FIG. 9 (f), the direction perpendicular to the paper surface in FIG. 11). The cable 110 outside from the opening 140 is freely movable in all the axial and radial directions of the cable 110. On the other hand, as shown in FIG. 11, when the cable 110 reaches the gap 180, even if the cable 110 is pulled in the axial direction, the cable 110 is bent at the leading edge 173 and abuts. Movement is limited by frictional forces. Furthermore, the radial movement of the cable 110 is limited only in the width direction of the gap 180 (the direction of the gap width R in FIG. 9F). And if it reaches the notch part 190, the movement of the width direction will also be restrict | limited. Thus, as the movable range of the cable 110 advances from the gap 180 to the notch 190, the displacement is limited in stages (the degree of freedom of movement is limited in stages), and the displacement is the movable distance of the cable 110. The amount is attenuated. Further, since the degree of restraint on the cable 110 increases stepwise, the force applied to the cable 110 from the outside is dispersed and gradually suppressed. Thereby, it is avoided that stress concentrates on one specific place, such as the cable 110 and a connection part.

The configuration of the opening-side inner wall 171 and the connector-side inner wall 172 having the shapes as described above, and the gap 180 and the notch portion 190 having predetermined shapes provided on them is integrally combined as a whole, so that the external cable 110 can be combined. Is operated to attenuate the stress and displacement applied to the cable 110. As a result, the external force applied to the cable 110 from the outside of the board case 100 is suppressed from being transmitted as it is to the cable 110 near the sub board side connector 132 inside the sub board case 102.
As a result, the force applied from the outside to the cable 110 is a type that does not concentrate on the sub board side connector 132, the sub cable side connector 122, the cable 110, and a specific part of each connection portion thereof. The sub-board case 102 can have a buffer function.

Therefore, the possibility of preventing breakage of the connecting portion, which is usually the most easily broken and easily damaged portion, can be increased. As a result, damage caused by a go-to action such as forcibly moving the cable 110 from the outside to attempt an unauthorized operation can be suppressed.
According to the present embodiment, as shown in FIGS. 5 and 8, in addition to the inner wall 170, a square frame 169 that protrudes toward the sub-board 92 is formed on the periphery of the opening 140. Yes. For this reason, it is possible to increase the possibility that foreign matter can be prevented from entering the direction other than the sub board side connector 132 from the opening 140 as well as the direction on the sub board side connector 132 side. In addition, by providing the square frame 169, the space in the area of the square frame 169 can be used as a cable storage portion that stores the cable 110 having an extra length by bending it. At that time, since the cable storage part is isolated from the surroundings by the square frame 169, the cable 110 to be stored comes into contact with the electronic components and wiring mounted on the periphery, and both of them are damaged or interfere with each other. It is possible to avoid such things. Furthermore, since the surface of the sub-board 92 facing the opening 140 forms a non-circuit region 94, the stored cable 110 may come into contact with the wiring and electronic components on the sub-board 92, causing inconvenience. It can be suppressed.

(Effects and effects mainly related to discovery of fraudulent activity by the visual confirmation unit 161, the non-circuit area 94, etc.)
The sub-board case 102 according to the present embodiment is arranged so that the connection terminal surface 133 (see FIG. 10) of the sub-board-side connector 132 faces the case lid member 160 side. The sub-board case 102 is formed with a visual confirmation part 161 made of a transparent member that can visually recognize the connection terminal surface 133. Thereby, a person who confirms the inside of the gaming machine 10 determines whether or not the sub-cable side connector 122 is properly connected to the connection terminal surface 133 from the outside through the visual confirmation unit 161 on the case lid member 160 side. Can see.
Then, the cable 110 from the sub-cable side connector 122 connected to the sub-board side connector 132 passes through the notch 190 of the connector-side inner wall 172 and the gap 180 of the opening-side inner wall 171 as shown in FIG. Thus, the sub-board 92 is guided toward the surface side. Therefore, a situation in which the cable 110 from the sub cable side connector 122 stays near the sub cable side connector 122 due to staying or meandering does not occur. Accordingly, the field of view from the case lid member 160 made of a transparent member is not significantly obstructed by the meandering cable 110 at the connection portion between the sub cable side connector 122 and the cable 110. As a result, a person who inspects and confirms the inside of the gaming machine 10 can visually observe the connection portion from the outside via the visual confirmation unit 161 without the visual field being significantly obstructed by the meandering of the cable 110. Can be confirmed.

As a result, from the outside of the case lid member 160, it becomes easy to visually confirm the connection terminal surface 133 of the sub-board-side connector 132 and the connection portion between the cable-side connector 120 and the cable 110 via the visual confirmation unit 161. For this reason, an illegal act on the sub-board-side connector 132 and its surroundings is easily detected.
According to the present embodiment, the portion from the opening 140 to the connector-side inner wall 172 is a non-circuit region 94 in which neither components nor wiring are arranged on the surface of the sub-board 92 (see FIGS. 3 and 5). ). Thereby, even if a foreign substance such as a wire is inserted from the opening 140, neither the component nor the wiring is arranged on the surface of the sub-board 92 of the inserted portion. It is possible to prevent an unauthorized operation such as a short circuit from being directly performed.

In addition, since no part or wiring is arranged in the portion from the opening 140 to the connector-side inner wall 172, the cable 110 does not come into contact with the part or wiring. Thereby, there is no possibility that the cable 110 may come into contact with parts or wiring during the installation work or the like and be damaged. In addition, the possibility of electrical interference between the two, such as adversely affecting electronic components due to electromagnetic waves emitted from the cable 110, can be reduced.
A portion from the connector side inner wall 172 to the board side connector 130 may also be provided in the non-circuit region 94. As a result, even if the cable 110 meanders to the surface side of the sub-board 92 and contacts the surface of the sub-board 92, there is a problem that the wiring and parts of the sub-board 92 are damaged by the contact of the cable 110 itself. Occurrence is avoided.

Here, the wiring region 95 (see FIG. 6) in which the wiring between the sub-board-side connector 132 and the portion that processes the data input from the sub-board-side connector 132 is applied It is formed on the back side of the surface on which the board-side connector 132 is provided. As a result, it is difficult to directly access the wiring in the wiring area 95 from the opening 140, and illegal activities such as obtaining or falsifying data input from the sub-board-side connector 132 are prevented. Is prevented.
According to the present embodiment, as shown in FIGS. 8 and 10, the sub-board-side connector 132 is stored in the peripheral side of the board case 100 in plan view with respect to the opening 140, specifically, in the board case 100. It is formed on the peripheral side of the sub-substrate 92 to be formed. As a result, other main electronic components and wirings excluding the sub board side connector 132 can be concentrated on the center side of the sub board 92, and the circuit on the sub board 92 can be efficiently connected with a short wiring distance. Can be.

As described above, in the present embodiment, the sub board-side connector 132 is provided on the front edge of the sub board 92, and the opening 140 is disposed near the center of the sub board 92. For this reason, the length of the cable 110 required inside the substrate case 100 can be shortened. As a result, it is possible to reduce the possibility of contact with the wiring or the like of the sub-board 92 and interference with electronic components due to electromagnetic waves.
(Effects and effects mainly related to improved mounting workability by the locking part 220 and the temporary fixing part 200)
According to the present embodiment, as shown in FIG. 7, the main cable side connector 121 is formed to be able to engage with the temporary fixing portion 200 of the sub-board case 102. As a result, the cable 110 exiting from the opening 140 to the outside of the sub-board case 102 is placed in a short state without drooping from the opening 140 for a long time. As a result, a space for replacement work such as attachment work and detachment work can be made wide and effective, and the work environment at the time of attachment becomes good. Further, when the sub-board case 102 that is not fixed to the housing 11 is transported, the sub-board case 102 is transported with the main cable side connector 121 engaged with the temporary fixing portion 200. For this reason, it is possible to prevent the main cable side connector 121 from colliding with surrounding members during transportation and damaging the main cable side connector 121 itself or the surrounding members. This protects the main cable-side connector 121 and surrounding members during transportation, and facilitates handling. Further, since the main cable side connector 121 is engaged with the temporary fixing portion 200 at the time of transport, a special protective cover for protecting the main cable side connector 121 at the time of transport becomes unnecessary. . Thereby, the number of parts can be reduced and cost reduction can be aimed at.

  In the board case 100, as shown in FIG. 7, the sub cable side connector 122 at one end of the cable 110 is connected to the sub board side connector 132 inside the sub board 92, so that the cable 110 A part is accommodated in the sub-board case 102. For this reason, the length of the cable 110 on the other side of the cable 110 (on the main cable side connector 121 side) and exposed to the outside from the opening 140 of the sub-board case 102 has such a configuration. Shorter than not. Thereby, the drooping of the cable 110 can be reduced. Furthermore, when a part of the cable 110 is forcibly accommodated inside the rectangular frame 169, the length of the cable 110 coming out of the opening 140 is further shortened, and drooping or the like is prevented.

  According to the present embodiment, as shown in FIG. 7, the middle portion of cable 110 that is led out of sub-board case 102 from opening 140 is hooked to locking portion 220. Then, in the hooked state, the sub cable side connector 122 at the tip of the cable 110 is temporarily fixed to the temporary fixing portion 200. As a result, the cable 110 does not hang down while the tip of the cable 110 is temporarily fixed, and as a result, extreme slack occurs in the cable 110 in the temporarily fixed state. The cable 110 is stored in a short length without any state occurring. Thereby, the middle of the temporarily fixed cable 110 hangs down or the middle of the slack cable 110 is less likely to collide with or be caught by surrounding parts. Therefore, damage to the cable 110, the sub-cable side connector 122, peripheral components, and the like can be suppressed. As a result, the protection of the cable 110 and surrounding parts can be improved.

  According to the present embodiment, as shown in FIGS. 14 and 15, the distance from the locking part 220 to the temporary fixing part 200 is the distance from the locking part 220 to the main board side connector 131 of the main board case 101. Longer. For this reason, the portion of the cable 110 that passes from the locking portion 220 to the temporary fixing portion 200 is used as the portion of the cable 110 that passes from the locking portion 220 to the main board side connector 131 of the main board case 101. As a result, the main cable side connector 121 at the tip of the cable 110 is removed from the temporary fixing portion 200 in a state where the cable 110 is kept locked without removing the cable 110 from the locking portion 220. The main board side connector 131 can be connected. Thereby, the connection work is simplified.

Further, the portion of the cable 110 extending from the locking portion 220 to the inside of the sub-board case 102 is maintained in a fixed state while being locked to the locking portion 220 as shown in FIG. For this reason, the portion of the cable 110 that extends from the locking portion 220 to the inside of the sub-board case 102 does not move during the connection operation, and there is no possibility that an excessive force is applied. Thus, the connection between the sub cable side connector 122 and the sub board side connector 132 is prevented from being disconnected inside the sub board case 102, and the connection portion is maintained well.
According to the present embodiment, as shown in FIG. 7, the length of the cable 110 is such that the cable 110 is locked from the opening 140 to the locking portion 220 and then folded back from the locking portion 220 to temporarily It is formed so as to be long enough to be temporarily fixed by the stopper 200.

  As a result, it is possible to prevent a situation in which the cable 110 hangs down without being able to be temporarily fixed to the temporary fixing portion 200 because the length of the cable 110 is insufficient. In addition, it is possible to prevent a situation in which the cable 110 hangs down when the cable 110 is unnecessarily long and temporarily fixed. As a result, the main cable-side connector 121 of the cable 110 that has gone out is securely fixed temporarily to the temporary fixing portion 200. This reduces the risk that the cable 110 that hangs down or slackens will collide with or be caught by surrounding parts. Therefore, it is possible to reduce the possibility that the cable 110, the cable-side connector 120, peripheral components, and the like are damaged.

According to the present embodiment, as shown in FIG. 7, the length of the cable 110 becomes longer than necessary, and the occurrence of sagging or slackening of the cable 110 is suppressed. As a result, it is possible to prevent the occurrence of a significant decrease in visibility such that a specific location of the sub-board 92 in the sub-board case 102 is hidden from view from the outside due to the presence of the slack cable 110. Is done. Therefore, even if an illegal operation (specifically, for example, ROM exchange) is performed on the sub-board 92, the possibility of being easily discovered from the outside is increased.
According to the present embodiment, as shown in FIG. 4, the sub-cable-side connector 122 can be inserted through the opening 140 due to the difference in shape, and the main-cable-side connector 121 can be inserted into the opening. 140 cannot be inserted. Therefore, as a work procedure, the worker first sets the sub cable side connector 122 through the opening 140 from the outside of the case lid member 160 (see FIG. 5), and then the sub cable side connector 122. Is connected to the sub-board-side connector 132 in the sub-board case 102. In such a work procedure, even if an operator mistakenly connects the main cable side connector 121 to be attached to the main board side connector 131 to the sub board side connector 132, the main board side connector 131 is opened. 140 cannot be inserted. For this reason, it is possible to prevent such an erroneous attachment procedure from being executed. As a result, the mounting workability can be improved, and damage to the board-side connector 130 and the cable-side connector 120 due to such erroneous work can be prevented.

  According to the present embodiment, as shown in FIG. 12, the protruding piece 240 is parallel to the outer surface so as to continue from a part of the recess 230 to the outer surface of the case lid member 160 of the sub-board case 102. It is formed to protrude. For this reason, the projecting piece 240 does not get in the way when transporting and storing a plurality of substrate cases 100 stacked one above the other. Thereby, when the substrate case 100 is transported or stored, the protruding piece 240 does not get in the way and is improved in handling during transport or storage. Further, since the protruding piece 240 is not formed so as to protrude in the vertical direction from the surface of the case lid member 160, the protruding piece 240 is not likely to come into contact with surrounding members or the like. Thereby, damage and deformation | transformation of protrusion piece 240 itself and a surrounding member are also prevented.

According to the present embodiment, as shown in FIG. 13, the cable 110 is inserted into the recess 230 in a state where the cable 110 is hooked on the protruding piece 240. When the cable 110 is filled into the recess 230, a part of the cable 110 is pushed toward the inside of the hole 232 of the recess 230 by the protruding piece 240. Thereby, a part of the cable 110 locked to the protruding piece 240 is released inside the hole 231. Therefore, it is avoided that an excessive force is applied to one portion of the locked cable 110 to be deformed, and disconnection of the cable 110 is prevented.
Since the protruding piece 240 can be elastically deformed, the protruding piece 240 can press the cable 110 locked around the protruding piece 240 toward the inside of the hole 232 of the recess 230. This prevents the locked cable 110 from being easily detached from the locking portion 220. Thus, since the protruding piece 240 can be elastically deformed and the hole 232 is provided in the bottom surface 231, the cable 110 can be locked to the locking portion 220 even when the diameter of the cable 110 is large to some extent. . This increases the allowable range of the diameter of the cable 110 that can be locked.

Usually, when the main cable side connector 121 is inserted into the temporary fixing part 200, the board case 100 is formed when both dimensions are formed so that the main cable side connector 121 is strongly held by the temporary fixing part 200. During the installation work, a large force is required to remove the cable-side connector 120 from the temporary fixing portion 200, and it is difficult to remove. On the other hand, if the cable-side connector 120 is formed so as to be held weakly by the temporary fixing portion 200, it can be easily removed with a small force, and the cable-side connector 120 is detached from the temporary fixing portion 200 when the board case 100 is transported. There is a risk of doing.
On the other hand, according to the present embodiment, the temporary fixing portion 200 is perpendicular to the front and back surfaces of the sub-board 92 inside the board case 100 (the sub-board case 102 is attached as shown in FIG. 14). When the main cable side connector 121 is inserted in the left direction), it can be temporarily fixed. In addition to this, the temporary fixing portion 200 is a surface that is perpendicular to the front and back surfaces of the sub-board 92 accommodated in the outer peripheral surface of the substrate case 100 (specifically, the sub-mounting portion 200 as shown in FIG. It is formed on the front surface when the substrate case 102 is attached. Further, the temporary fixing portion 200 is opened in a direction perpendicular to the front and back surfaces of the sub-board 92. For this reason, when only the sub-board case 102 having a rectangular parallelepiped overall shape that is not attached to the housing 11 is stacked flatly, the insertion direction of the main cable side connector 121 is not disturbed by the temporary fixing portion 200. A plurality of sub-board cases 102 can be stacked along (the direction in which the opening of the temporary fixing portion 200 faces). When the sub-board cases 102 are stacked in this way, the next sub-board case 102 is stacked from the state in which the main cable side connector 121 is inserted into the temporary fixing portion 200. In this case, even if the main cable side connector 121 is about to be detached from the temporary fixing portion 200 in the vertical direction, the main cable side connector 121 is pressed from above by the sub-board cases 102 stacked next. Therefore, the main cable side connector 121 is prevented from falling off from the temporary fixing portion 200. The board case 100 according to the present embodiment is formed so that the main cable side connector 121 does not easily fall off from the temporary fixing portion 200 even when stored and transported in a state where the sub board cases 102 are stacked. In addition, when the sub board case 102 is installed, the main cable side connector 121 is held so as to be easily removed.

  Further, according to the present embodiment, as shown in FIG. 16, the temporary fixing portion 200 has the main cable-side connector 121 that opens in a direction perpendicular to the surface of the sub-board 92 inside the sub-board case 102. ing. For this reason, the sub cable side connector 122 is temporarily fixed by being inserted in a direction perpendicular to the surface of the sub board 92. At this time, the cable 110 extending from the temporarily fixed main cable side connector 121 is arranged in a direction perpendicular to the sub board 92 and the sub board case 102 and away from the sub board case 102. Since the cable 110 does not stay parallel or meander along the surface of the sub-board case 102, the cable 110 stays when observing the inside of the sub-board case 102 made of a transparent member from the outside. Visibility does not deteriorate significantly. As a result, the sub-board case 102 maintains good visibility. Therefore, even if an illegal operation (specifically, for example, ROM exchange) is performed on the sub-board 92, it is easily detected from the outside.

Further, when the main cable side connector 121 is pulled out from the temporary fixing portion 200, the main cable side connector 121 is pulled out in a direction perpendicular to the sub-board case 102 as shown in FIG. For this reason, the main cable side connector 121 can be easily detached from the temporary fixing portion 200 because the main cable side connector 121 can be pulled in a direction where there is no other surrounding member inside the housing 11. As a result, when the wiring between the sub board 92 and the main board 91 is performed by the harness 105 after the sub board case 102 and the main board case 101 are attached to the housing 11, such wiring work should be facilitated. Can do.
According to the present embodiment, as shown in FIG. 13, over the substantially entire length of the cable 110, the four covered electric wires 112 are covered with the tubular cover 111 in a bundled state. As a result, the cable 110 is protected and illegal acts on the cable 110 are prevented. Further, since the cable 110 covered with the tubular cover 111 is formed so as to be able to be locked to the locking portion 220, disconnection or the like of the locked position is prevented. In the cable 110, a plurality of covered electric wires are bundled into one by a tubular cover 111. For this reason, handling is convenient and wiring work is easy.

The opening 140 is also formed so that the cable 110 covered with the tubular cover 111 can be inserted. This prevents illegal acts on the cable 110 and increases the possibility of preventing disconnection at the edge of the opening 140 when the cable is inserted into the opening 140. Further, the tubular cover 111 is formed of a transparent resin that is a transparent member. For this reason, the external appearance state of the covered electric wire 112 inside the cable 110 can be easily grasped from the outside, and it becomes easy to find fraud and disconnection.
(Other)
According to the present embodiment, since it is possible to suppress the occurrence of fraudulent acts on the sub-board 92, production information that affects the profit (out of play) of the player output from the main board 91 to the sub-board 92, for example, The possibility that information such as an ART game (assist replay time game) is illegally acquired can be reduced.

In the present embodiment, the sub-board case 102 is formed with the inner wall 170, the opening 140, the locking part 220, the temporary fixing part 200, etc., but is not particularly limited to the sub-board case 102. . For example, even if they are provided in another substrate case 100 such as the main substrate case 101, the same operation and effect can be obtained.
Further, the gaming machine 10 is not limited to a slot machine, and may be a gaming machine 10 that performs other types of games such as a pachinko machine. The contents described in the present embodiment can be applied to the board case 100 of the gaming machine 10 in general that is likely to be cheated.
