<Noise countermeasures>
In general, a ferrite core is known as a noise countermeasure component. However, when adopting a ferrite core in a game machine such as a pachislot machine or a pachinko machine, it is necessary to prevent a wind legal problem from occurring. That is, there is a problem peculiar to the industry that a gaming machine such as a pachislot machine or a pachinko machine must always be restored to the same state as tested by the Security Communication Association.

  On the other hand, if an optical cable is used as a communication cable, it is not affected by noise. However, since an optical cable is more expensive than a metal cable, it is difficult to use the optical cable for all communication cables. In addition, unlike an optical cable, an optical cable cannot flow current, and therefore has a problem that it is not suitable for power supply.

  Therefore, in the pachislot machine 1 according to an embodiment of the present invention, noise countermeasures are taken by attaching a ferrite core to a metal cable. For example, as shown in FIG. 5, it is difficult to use an optical cable from the power supply surface for the cables C1, C2, C3, and C4 connected to the power supply board 36b of the power supply device 36, so use metal cables. The ferrite core is attached.

<Ferrite core case>
Hereinafter, the ferrite core case 100 in one embodiment of the present invention will be described.

[overall structure]
FIG. 6 is a perspective view showing a ferrite core case 100 in one embodiment of the present invention. This ferrite core case 100 is a ferrite core case 100 that is attached to a cable 130 used in a gaming machine such as a pachislot machine 1, and as shown in FIG. 6, a ferrite core 110 through which the cable 130 is inserted, and a ferrite core And fixing means 120 for fixing the position and orientation of attaching 110 to the cable 130. That is, the ferrite core case 100 includes the ferrite core 110 and the fixing means 120. The cable 130 is a variety of cables that need noise countermeasures, such as the cables C1, C2, C3, and C4 connected to the power supply board 36b of the power supply device 36.

  According to such a configuration, since the magnetic field generated from the cable 130 is absorbed by the ferrite core 110, noise can be appropriately removed. Even if the ferrite core 110 is once removed from the cable 130, the fixing position 120 fixes the mounting position and orientation of the ferrite core 110. It is possible to return to the state.

[Bundling means]
7A and 7B are diagrams showing the fixing means 120 according to the embodiment of the present invention, in which FIG. 7A is a top view, FIG. 7B is a front view, and FIG. 7C is a right side view. As shown in this figure, as the fixing means 120, a bundling means 120 such as a harness accessory having an Insulok (registered trademark) structure for bundling and tightening the cable 130 can be employed. According to such binding means 120, it is possible to fix the mounting position and orientation of the ferrite core 110 by a simple method of binding and tightening the cable 130.

  Specifically, as shown in FIG. 7, the cable 130 is bundled by a band 121 that is curved in a C shape in a side view, and is tightened by a band stopper 124 with a binding force that does not move in the axial direction of the cable 130. An arrowhead-shaped convex portion 123 protrudes from one end (lower end) of the outer periphery of the band 121 through the flange portion 122. The formation method of each of these parts is not particularly limited. For example, they can be integrally formed by molding a thermoplastic resin having elasticity.

[Ferrite core]
8A and 8B are diagrams showing a ferrite core 110 according to an embodiment of the present invention, where FIG. 8A is a top view, FIG. 8B is a front view, and FIG. 8C is a right side view. As shown in this figure, the ferrite core 110 is a cylindrical member made of ferrite and includes a columnar insertion hole 114 through which the cable 130 is inserted. A concave portion 112 is formed at a predetermined position (described later) of the ferrite core 110, and a fitting hole 112 a is formed at the central portion of the bottom of the concave portion 112. When the convex portion 123 of the bundling means 120 is fitted into the concave portion 112 and penetrates through the fitting hole 112a, the arrowhead of the convex portion 123 opens to the outside and the reverse is prevented. The opening shape of the concave portion 112 is formed in a cross shape in a top view in accordance with the collar portion 122 of the bundling means 120, and the rotation of the collar portion 122 is prevented by the four rotation prevention pieces 113 protruding inside the opening of the concave portion 112. It has a structure.

  Thus, when the convex part 123 of the bundling means 120 is fitted into the concave part 112 of the ferrite core 110, the bundling means 120 and the ferrite core 110 can be firmly connected. That is, since the convex part 123 of the bundling means 120 has an arrowhead shape, it can be prevented from coming off from the concave part 112 of the ferrite core 110. Further, since the rotation preventing piece 113 is provided in the concave portion 112 of the ferrite core 110, it is possible to prevent the convex portion 123 of the bundling means 120 from rotating within the concave portion 112 of the ferrite core 110.

  FIG. 9 is a view for explaining the opening shape of the recess 112 of the ferrite core 110 according to the embodiment of the present invention. When the recess 112 is viewed from directly above, it has a horizontally long cross shape as shown in FIG. 9A, but when rotated 90 °, it becomes a vertically long cross shape as shown in FIG. 9B. That is, the opening shape of the recess 112 is different when rotated 90 ° (has asymmetry).

  According to such a configuration, the direction in which the convex portion 123 of the bundling means 120 is fitted into the concave portion 112 of the ferrite core 110 is limited. That is, even if the convex portion 123 is to be fitted in the wrong direction, the convex portion 123 cannot be fitted to the bottom of the concave portion 112 due to the opening shape of the concave portion 112. When the convex portion 123 is fitted in the correct direction, the arrowhead opens through the fitting hole 112a formed in the bottom of the concave portion 112, and the cable 130 is inserted into the bundling means 120 as shown in FIG. 9C. The insertion direction D1 in which the cable 130 is inserted through the ferrite core 110 is parallel to the insertion direction D2. Of course, “parallel” here may include an error.

  In this way, if the insertion directions D1 and D2 are parallel, the cable 130 can be wound while looking good and saving space by winding it in two turns or the like. In addition, when mass-producing a gaming machine in the same state as tested by the Security Communication Association, there is an effect of preventing the cable 130 from being mistakenly wound.

  FIG. 10 is a perspective view showing a ferrite core 110 according to an embodiment of the present invention, where (a) shows a closed state, and (b) shows an open state. As shown in this figure, the ferrite core 110 is a two-part ferrite core whose one end (lower end) opens and closes, and includes a recess 112 on the other end (upper end) side facing the one end (lower end).

  Specifically, a semi-cylindrical first main body 111a and a second main body 111b which are divided into two in the insertion direction D2 through which the cable 130 is inserted are provided, and the outside is covered with a cover member 111c. The cover member 111c can be formed of an elastic resin or the like. When a force for pulling outward is applied at the lower ends of the first main body 111a and the second main body 111b, the lower end is opened by being pivoted on the upper side. If no force is applied, the lower end is closed by the elastic force of the cover member 111c. According to such a configuration, the side opposite to the side on which the bundling means 120 is provided opens and closes, so that the cable 130 can be easily inserted into the ferrite core 110 by a winding method such as two turns.

[Installation procedure]
FIG. 11 is a diagram showing a procedure for attaching the ferrite core case 100 to the cable 130 in one embodiment of the present invention. Here, as shown in FIG. 11A, a wire harness provided with connectors 131 and 132 at both ends is illustrated as the cable 130. That is, various electrical components such as a control board are provided on the back side of the game board. These electrical components are electrically connected by an electrical wiring bundle in which a plurality of electrical wirings are bundled. At both ends of the electrical wiring bundle, connectors for joining the electrical component and the electrical wiring bundle are provided. A part obtained by integrating the electrical wiring bundle and the connector is generally called a “wire harness”.

  First, as shown in FIG. 11B, the bundling means 120 having an insulation lock structure is attached to the cable 130 for positioning. Next, as shown in FIG. 11 (c), the convex portion 123 of the bundling means 120 is fitted into the concave portion 112 of the ferrite core 110. It is also possible to change the order of FIG. 11B and FIG.

  After that, the cable 130 is inserted into the ferrite core 110 and set so as to be in the same state as the state tested by the Security Communication Association. For example, the cable 130 is turned with the lower end of the ferrite core 110 opened, and the lower end of the ferrite core 110 is closed with the cable 130 passed through the ferrite core 110. Thereby, as shown in FIG. 11D, the cable 130 can be easily inserted into the ferrite core 110 in two turns.

  Thereafter, it is assumed that the ferrite core 110 needs to be temporarily removed from the cable 130 in order to confirm that the cable 130 is normal. In such a case, since the conventional ferrite core case does not have a positioning structure, it is very difficult to return the ferrite core to its original state without a jig.

  In this respect, according to the ferrite core case 100 in one embodiment of the present invention, since the mounting position and orientation of the ferrite core 110 are fixed by the bundling means 120, it is easy to simply wind the cable 130. It is possible to return to the state before removal. That is, as shown in FIG. 11D, even when the cable 130 is attached to the ferrite core 110 with two turns, when the lower end of the ferrite core 110 is opened and the cable 130 is unwound, as shown in FIG. The portion hidden inside the ferrite core 110 can be visually recognized from the outside. Thus, when it is confirmed that there is no abnormality in the cable 130, the cable 130 may be inserted through the ferrite core 110 again in two turns as shown in FIG.

  Such a ferrite core case 100 is particularly effective when applied to a gaming machine that is required to undergo a test under regulations or laws and to maintain the test. That is, since it can be restored to the same state as the state tested by the Security Communication Association, it is possible to provide a gaming machine that does not cause any problem in terms of wind law.

  In addition, although 2 turns are illustrated here as how to wind the cable 130, you may employ | adopt other winding methods (3 turns etc.). That is, as long as the position and orientation of attaching the ferrite core 110 to the cable 130 can be fixed by the fixing means 120, the same effect can be obtained regardless of how the cable 130 is wound.

[Modification of fixing means]
FIGS. 12A and 12B are views showing a state in which the fixing unit 120 according to another embodiment of the present invention is attached to the cable 130, where FIG. As shown in this figure, the fixing means 120 may be a banding 120 formed of an elastic resin or the like. In this example, a flat cable 130 is inserted through a banding 120 having a part 125 of the upper surface opened in the longitudinal direction. If the band-passage 120 sandwiches the cable 130 with an elastic force that does not move in the axial direction of the cable 130, the position and orientation in which the ferrite core 110 is attached to the cable 130 can be fixed.

  Of course, the modification of the fixing means 120 is not limited to this. For example, various modifications such as forming a locking groove on the outer side of the cable 130 for preventing the ferrite core 110 from moving in the axial direction are possible.

[Modification of ferrite core]
13A and 13B are perspective views showing a ferrite core 110 according to another embodiment of the present invention, in which FIG. 13A is a diagram showing a closed state, and FIG. 13B is a diagram showing an open state. As shown in this figure, the outer periphery of the end face of the ferrite core 110 is a vertically long octagon, and the inner periphery of the end face of the ferrite core 110 is a quadrangle combining two opposite sides of the octagon. May be. A recess 112 is formed on the short side (upper side) of the vertically long octagon. The other points are basically the same as those of the cylindrical ferrite core 110 (see FIG. 10).

  According to such a configuration, the insertion hole 114 is formed in a flat plate shape, which is suitable when the ferrite core case 100 is attached to the flat cable 130. That is, the ferrite core case 100 can be easily attached without deforming the outer shape of the flat cable 130. Moreover, since the outer periphery of the end face of the ferrite core 110 is an octagon, space saving can be achieved compared to a case where the ferrite core 110 is circular. Furthermore, since it is chamfered in an octagon, there is an effect that it is easy to use.

[Modification of ferrite core case]
FIG. 14 is a view showing a ferrite core case 100 according to another embodiment of the present invention, in which (a) is a top view, (b) is a front view, and (c) is a right side view. As shown in this figure, the ferrite core 110 and the bundling means 120 may be integrally formed. In this case, since the structure for connecting the ferrite core 110 and the bundling means 120 is not limited, it is not always necessary to form the convex portion 123, the concave portion 112, the flange portion 122, and the like, and the degree of freedom in design increases.

[Modification of installation procedure]
FIG. 15 is a diagram showing a procedure for attaching the ferrite core case 100 shown in FIG. 14 to a cable. First, as shown in FIGS. 15 (a) and 15 (b), the binding means 120 formed integrally with the ferrite core 110 is attached to the cable 130. Next, the cable 130 is turned with the lower end of the ferrite core 110 opened, and the lower end of the ferrite core 110 is closed with the cable 130 passed through the ferrite core 110. Thereby, as shown in FIG. 15C, the cable 130 can be easily inserted into the ferrite core 110 in two turns. Thereafter, the procedure for confirming that there is no abnormality in the cable 130 is the same as the previous example (see FIG. 11).

  As already described, when the ferrite core 110 and the bundling means 120 are integrally formed, the connection structure between the ferrite core 110 and the bundling means 120 is not limited, so that there is an advantage that the degree of design freedom is increased. On the other hand, when the ferrite core 110 and the bundling means 120 are formed separately, only the bundling means 120 can be attached to the cable 130 and positioned in advance, so that the assembly process of the gaming machine can be simplified. There is. You should choose the one that is easy to use according to the situation.
