The unauthorized radio wave detection device 40 is arranged with a predetermined directionality at a predetermined position on the back of the game board near the entrance detection magnetic sensor, for example, and is transmitted from the transmitter to the entrance detection magnetic sensor by a so-called radio goto. It is used to detect the illegal radio waves that are transmitted.
The unauthorized radio wave detection device 40 includes a printed circuit board 41 mounted with a coil antenna 45 for detecting unauthorized radio waves and other electronic components (detection circuit, etc.) in a box-shaped printed circuit board storage container (resin case) 50. It has a housed configuration. The coil antenna 45 is a means for receiving an illegal radio wave having a frequency that causes the magnetic sensor for detecting the incoming ball to malfunction, and the other electronic components constitute a detection circuit that detects the illegal radio wave from the radio wave received by the coil antenna 45. When an illegal radio wave is detected by the detection circuit, the control device (not shown) is notified via the lead wire 43.

The printed circuit board 41 has a lead wire 43 drawn out from the connector portion 42 at the rear end edge, and includes a pair of small protrusions 44 at two opposite side edge edges. The coil antenna 45 mounted near the front end of the printed circuit board is a means for receiving unauthorized radio waves. The accuracy of the unauthorized antenna detection accuracy transmitted from the external transmitter to the magnetic sensor for detecting the incoming ball is determined by the coil antenna 45. It depends on the direction.
Even if the unauthorized radio wave detection device 40 is correctly fixed at a predetermined position on the back side of the game board with a predetermined directionality, the positions of the printed circuit board storage container and the printed circuit board (particularly, the coil antenna 45) stored therein. When there is a deviation in the relationship, it becomes impossible to detect illegal radio waves effectively. For this reason, in order to improve the positioning accuracy of the printed circuit board in the printed circuit board storage container, it is particularly necessary to uniquely position the printed circuit board in the surface direction and the thickness direction.

The printed circuit board storage container 50 includes a case main body 51 having an open top surface and a capacity sufficient to store the printed circuit board 41, a lid 70 fixed to the case main body in a state where the opening 52 of the case main body is closed, It is composed of
The case main body 51 includes a bottom plate 54 having an upper surface facing the lower surface of the accommodated printed circuit board 41, a side wall 56 erected from two opposite side edges of the bottom plate, a front edge and a rear end of the bottom plate 54.

The two side walls 56 are each provided with a positioning portion 56a for positioning each pair of small protrusions 44 of the printed circuit board and a main body side locking portion (locking hole) 56b. On the front wall 58, a pair of left and right guide protrusions 58a extending in the vertical direction at a position corresponding to the front edge of the printed circuit board, and a lower guide protrusion 58b having a low height disposed below the pair of guide protrusions, Is provided. The lower guide projection 58b is configured to have a flat upper surface so as to support the lower surface of the center portion of the front edge when the printed circuit board is accommodated in the case body 51. The pair of guide protrusions 58a are triangular pillars having a triangular planar shape, and are configured to guide the front edge of the printed circuit board at the sharp tip when the printed circuit board is accommodated in the case body. . The rear wall 60 is formed with a recess (notch) 60a for drawing out a lead wire 43 extending from a printed circuit board housed in the case body. Further, a lower guide projection 62 is provided on the inner side of the rear wall 60 for supporting the bottom surface of the printed circuit board on the upper surface when the printed circuit board is stored in the case body. The lower guide protrusions 58b and 62 have the same height, and support the printed circuit board in parallel with the bottom plate 54 of the case body by supporting the lower surface near the front end and the lower surface near the rear end of the printed circuit board with their flat upper surfaces, respectively. Hold in posture.
A chamfered portion 51 a is provided at one corner of the case body 51 corresponding to the chamfered portion 41 a provided at one corner of the printed circuit board 41. When the printed circuit board is stored in the case main body, the storage can be smoothed by aligning the chamfered portions. If a chamfer is not provided, one corner of the printed circuit board may get caught with the corresponding corner of the case body and storage may not be smooth. It becomes.

  The lid body 70 has a top plate 72 that faces the bottom plate 54 of the case body and closes the opening 52, and a projecting piece that can be fitted between a pair of guide projections 58a depending on the center of the front edge of the top plate 72. 74 and a lid-side engagement provided with locking projections 76a that protrude downward from both opposite side edges of the top plate and detachably engage with the main body side locking portions 56b when being press-fitted inside the side plates 56, respectively. A stopper 76 and a rear protruding piece 78 that protrudes downward from both sides of the rear edge of the top plate and enters the inside of the rear wall 60 of the case body when the lid is closed are provided. Each lid side locking portion 76 includes a locking projection 76a that can be locked to the main body side locking portion (locking hole) 56b in a one-to-one manner on the lower outer surface, and the opening 52 of the case main body by the lid. When the lid side locking portions 76 are press-fitted inside the side plates 56 in the process of closing the lid, the locking projections 76a are locked from the inside to the main body side locking portions 56b, so that the lid body Omission is prevented.

A chamfered portion 72 a is formed on the top plate 72 at a position corresponding to the chamfered portion 51 a of the case main body.
A notch 78a formed between the two rear projecting pieces 78 cooperates with a recess 60a in the rear wall of the case body to hold the lead wire 43 while pulling it out.
The projecting piece 74 provided at the front edge of the lid body is fitted in between the guide ridges when the top plate 72 closes the opening 52 of the case body with the printed board stored in the case body. And it is comprised thickly so that the upper surface along the front-end edge of the printed circuit board accommodated in the case main body may be pressed with a front-end | tip part (lower surface). Therefore, when the printed circuit board is housed in the case body, the front end portion of the printed circuit board is held between the lower guide protrusion 58 b and the protruding piece 74.

Next, a procedure for storing the printed circuit board in the printed circuit board storage container 50 will be described with reference to FIGS.
As shown in FIG. 8A, the outer contour of the printed circuit board 41 is configured to fit into the recess of the case body 51. When the printed circuit board is stored, the small protrusion pairs 44 provided on both side edges of the printed circuit board are positioned while being guided by the positioning portions 56a (FIGS. 9, 10, and 11). When the printed circuit board is housed, the triangular prism-shaped positioning part 56a enters between the small protrusions 44 and guides it, so that the printed circuit board is prevented from being displaced in the front-rear direction and the lateral direction. Further, when the printed circuit board is stored, the front end edge thereof is guided by the pair of guide protrusions 58a having sharp points, thereby further preventing the displacement in the front-rear direction (FIG. 9). Further, the lower fixed position of the printed circuit board can be determined by supporting the lower surface near the front end and the lower surface near the rear end of the printed circuit board by the flat upper surfaces of the lower guide protrusions 58b and 62 having the same height. (FIG. 9B). Further, when the case body is closed by the lid body 70, the projection piece 74 of the lid body pushes down the upper surface near the front end of the printed circuit board. It becomes possible to fix to a proper posture (FIG. 9B).

  When the lid is closed with respect to the case main body, the projecting piece 74 is fitted between the pair of guide projections 58a and moves while being guided. It is possible to always push down the predetermined position. When the case body is closed (when all the main body side locking portions 56b and all the locking protrusions 76a are locked), the printed circuit board is pinched by the lower surface of the projecting piece 74 and the upper surface of the lower guide protrusion 58b. Since it is held, the positional deviation of the printed board in the vertical and horizontal directions is eliminated (FIGS. 9 and 10).

As described above, in the printed circuit board storage container 50 of the present invention, when the printed circuit board is stored in the case main body, the lateral position and the front and rear position of the printed circuit board are positioned with respect to the small protrusion pair 44 and the positioning portion 56a. , The engagement between the pair of guide protrusions 58a and the front edge of the printed circuit board, and the engagement between the rear wall 60 of the case body and the rear edge of the printed circuit board. Further, the positioning and posture of the printed circuit board in the vertical direction in the case main body are performed by engaging the lower guide protrusions 58b and 62 with the lower surface of the printed circuit board, and the printed circuit board between the lower guide protrusion 58b and the protruding piece 74. This is realized by holding the pressure.
For this reason, the directivity of the coil antenna 45 with respect to the case main body can be uniquely defined simply by storing the printed circuit board in the case main body and closing the lid body. If there is no mistake in the mounting position and mounting direction of the detection device 40, the coil antenna 45 can always be installed in the correct direction, and the detection accuracy of unauthorized radio waves can be maintained.

Since the lead wire 43 is pulled out from the rear part of the printed circuit board, when the printed circuit board is stored in the case body, the lead wire 43 is easily caught in the recess 60a, and the posture of the printed circuit board is maintained parallel to the bottom plate 54. However, in the present invention, the engagement between the pair of small protrusions 44 and the positioning portion 56a, the engagement between the pair of guide protrusions 58a and the front edge of the printed circuit board, the rear wall 60 of the case body and the print The printed circuit board can be stably stored in a posture parallel to the bottom plate 54 by using the engagement with the rear edge of the substrate as a clue.
In the above embodiment, when the lid is closed, the front end of the lid side locking portion 76 is separated from the printed circuit board. However, a part of the lid side locking portion 76 is in contact with the upper surface of the printed circuit board in the vertical direction. You may comprise so that positioning may be performed. That is, for example, as shown in FIG. 12, a part of the lid side locking portion 76 (a portion avoiding the positioning portion 56a) 76b may be extended so as to be in contact with the upper surface of the printed board. If comprised in this way, it will become possible to perform the positioning of the up-down direction of the both-ends edge of the accommodated printed circuit board still more reliably.

  Thus, according to the printed circuit board storage container 50 of the present invention, it is possible to reliably position not only the position in the surface direction of the printed circuit board with respect to the case body but also the position in the thickness direction (vertical direction). In particular, if unauthorized radio waves cannot be received or detected if the direction of the coil antenna on the printed circuit board is slightly deviated, positioning accuracy of the printed circuit board with respect to the case body is important. However, in the present invention, positioning with high accuracy is possible. Therefore, the detection accuracy can be maintained. Specifically, the lead wire drawn from the printed circuit board causes the printed circuit board to float when the printed circuit board is housed in the case. In the present invention, the upper surface of the printed circuit board is covered by the protrusion 74 provided on the lid. Since the lid is closed while being pressed, it is possible to reliably prevent lifting. Since the protrusion 74 is thick, the upper surface of the printed circuit board can be pressed down by another portion while being partially guided by the guide protrusion 58a. That is, the projecting piece 74 can press the printed circuit board on the tip surface while moving along a stable linear locus by the guide projection.

In the case where the upper surface of the printed circuit board is suppressed by the lid side locking portion 76, the printed circuit board can be further prevented from rising.
When storing the printed circuit board in the case body, the workability is improved by inserting the printed circuit board so that the front edge of the printed circuit board is inclined downward. By storing the front end edge of the printed circuit board while simultaneously contacting the front end of the strip 58a, workability during storage can be further improved. Next, after the bottom surface of the printed circuit board comes into contact with the top surface of the lower guide protrusion 58b, the small protrusions 44 on the printed circuit board are engaged with the positioning portions 56a, thereby completing the positioning in the surface direction of the printed circuit board. To do.
In the above embodiment, an example in which the printed circuit board storage container 50 of the present invention is applied to the unauthorized radio wave detection device 40 is shown, but the present invention can be applied to general resin containers that store printed circuit boards.
