  Next, the game ball guide rod 420 and the surrounding structure will be described with reference to FIGS.

  In FIG. 3, the storage tank 400 has a box shape with an open top, and game balls are supplied from the island facility. A game ball drop hole (not shown) opened in the game ball guide rod 420 is formed on the bottom surface of the storage tank 400, and the bottom surface is gently inclined downward toward the game ball drop hole. Therefore, the game ball supplied from the island facility is guided to the game ball drop hole along the inclination of the bottom surface, and is guided from the game ball drop hole to the game ball guide bar 420.

  3, 4, 5, and 6, the game ball guide rod 420 disposed immediately below the storage tank 400 is a first flowing-down side wall 420 a on the front side of the drawing, and the first flowing-down side wall. It has a second falling side wall 420b opposite to 420a and an upstream side wall 420c on the left side of the drawing. Further, the bottom portion 420d is gently inclined downward from the position where the game ball dropped from the game ball drop hole toward the game ball flow passage 410, and the game ball rolls down by the bottom portion 420d. . Further, no side wall is formed at the downstream end, so that the game ball reaching the end is guided to the game ball flow passage 410.

  At the center of the bottom 420d of the game ball guide rod 420, a partition wall 420e is erected so as to extend to the downstream end along the flow direction of the game ball. Thereby, the space sandwiched between the first falling wall 420a and the partition wall 420e becomes the first guide path 421a having a width slightly larger than the diameter of the game ball, and the second falling wall 420b, the partition wall 420e, Similarly, the space between the two is a second guide path 421b having a width slightly larger than the diameter of the game ball. Then, one game ball is aligned with each of the first guide path 421a and the second guide path 421b and flows down in two rows.

  In this embodiment, there are two guiding paths, but one or three or more guiding paths may be formed.

  A pair of guide rails 422 are erected along the length direction of the guide paths 421a and 421b on the first guide path 421a and the second guide path 421b. The guide rail 422 has a width that is narrower than the diameter of the game ball. By such a guide rail 422, the game ball flows down in the guide paths 421a and 421b in a non-contact state with the bottom 420d.

  A foreign substance drop hole 423 is formed between the pair of guide rails 422 provided on the bottom part 420 d of the game ball guide bar 420. The foreign material drop hole 423 removes foreign matter in the game ball guide rod 420, and by dropping foreign matter such as dust and plating dust attached to the game ball or flying dust from the foreign matter drop hole 423, It prevents the foreign matter from accumulating on the game ball guide rod 420 and hindering the smooth flow of the game ball.

  In the present embodiment in which the foreign substance drop hole 423 is slit-shaped, the foreign substance drop hole 423 is used to prevent a decrease in the rigidity of the game ball guide rod 420 due to the opening of the foreign substance drop hole 423 being formed in the bottom part 420d. On the lower side, a reinforcing plate 424 is provided as appropriate.

  In this embodiment, the foreign substance drop hole 423 is formed between the pair of guide rails 422, but may be formed outside the guide rails 422. Alternatively, it may be formed both between and outside the guide rail 422.

  Further, in the present embodiment, the foreign substance drop hole 423 is a slit, but the hole shape is not limited to this, and various shapes such as a collection of a large number of round holes can be adopted.

  Since the foreign object drop hole 423 must remove the foreign object in the game ball guide rod 420 while preventing the game ball from falling, the foreign object drop hole 423 is free as long as its width is smaller than the diameter of the game ball. Its dimensions can be set.

  The guide paths 421a and 421b partitioned by the partition wall 420e and the guide rails 422 in the guide paths 421a and 421b may not be formed. However, it is preferable to form the game balls because the game balls are not aligned without the guide paths 421a and 421b, and it is difficult to smoothly roll down. In addition, with respect to the guide rail 422, in particular, when a plurality of foreign object drop holes 423 are divided along the flow direction of the game ball, the foreign object drop holes 423 become steps when the game ball flows down. It is desirable that it is formed because it is difficult to smoothly roll down.

  As described above, the board case 110 of the sub control board having the opening 111 opened upward is disposed below the gaming ball guide bar 420 having such a structure.

  Between the game ball guide rod 420 and the substrate case 110, a foreign material introduction portion 430 into which foreign materials dropped and discharged from the foreign material drop hole 423 formed in the game ball guide rod 420 is provided. The foreign material introducing portion 430 is provided at a position including the upper portion of the opening 111 opened toward the foreign material dropping hole 423 so that the falling foreign material from the foreign material dropping hole 423 does not enter the opening 111. Therefore, the position of the foreign substance introduction part 430 is irrelevant to the opening part that is not opened toward the foreign substance drop hole 423 (that is, the opening part other than the reference numeral 111).

  In the illustrated case, the foreign material introducing portion 430 is integrally formed with the game ball guiding rod 420 and is open to the outside, and includes a base plate 440 common to each other. According to such integral formation, the number of parts can be reduced and the assembly process can be simplified as compared with the case where the two are formed separately, so that the cost can be reduced.

  In the present embodiment, foreign substance introducing portion 430 is provided integrally with game ball guiding rod 420, but may be integrated with substrate case 110 or other members.

  The foreign material introduction portion 430 includes a bottom portion 430a in which fallen foreign materials are stored, and a side plate portion 430b that supports the bottom portion 430a at three locations, and the bottom portion 430a extends so as to protrude outward from the base plate 440 (see FIG. 6). ). The bottom portion 430a is located on the upstream side of the game ball in the flow direction of the game ball in the game ball guide rod 420, and is positioned lower than the first bottom portion 430a-1 on the downstream side of the game ball in the flow direction. The second bottom portion 430a-2. One of the side plate portions 430b described above supports the end of the first bottom portion 430a-1 opposite to the second bottom portion 430a-2, and one side is the second bottom portion 430a-2. One end portion opposite to the bottom portion 430a-1 is supported, and one end portion supports a step portion formed by the first bottom portion 430a-1 and the second bottom portion 430a-2. In addition, the bottom part does not have such a level | step difference, and may be the same plane. Moreover, the bottom part may be supported in places other than three places.

  Since the foreign substance introduction part 430 is provided, the foreign substance dropped from the foreign substance drop hole 423 of the game ball guide rod 420 is introduced into the foreign substance introduction part 430, and thus from the opening 111 of the substrate case 110. It is prevented from entering the inside. As a result, there is no possibility of foreign matter adhering to the board (here, the sub-control board) in the board case 110, causing an electrical short circuit, and an accurate operation of the gaming machine can be ensured.

  Note that since the foreign material introduction portion 430 is open toward the outside, the introduced foreign material can be easily taken out during maintenance of the gaming machine or the like.

  Here, as shown in detail in FIG. 6, in the present embodiment, bottom portion 430 a protrudes outward from surface 110 a of substrate case 110. In this way, foreign objects are more difficult to enter, so a larger opening can be secured for heat dissipation or for connector insertion. Note that it is sufficient that the bottom portion 430a protrudes outwardly to the same extent as or more than the surface 110a of the substrate case 110. Further, as long as the bottom portion 430 a is located at a position including the upper portion of the opening 111, the bottom portion 430 a does not necessarily have to protrude beyond the surface 110 a of the substrate case 110.

  Further, if the bottom portion 430a is inclined downward toward the outside, the introduced foreign matter can easily fall to the island facility side along the bottom portion 430a, so that the foreign matter does not easily accumulate in the foreign matter introduction portion 430 and is removed. Frequency is reduced.

  In the embodiment described above, the foreign substance introduction part 430 has a shape opened toward the outside, but may be a box-shaped body having side walls over the entire circumference. If the box-shaped body is used, the fallen foreign matter can be reliably trapped in the foreign matter introduction portion 430.

  In addition, the foreign material introducing portion 430 is integrally formed with the game ball guiding rod 420, but as shown in FIG. 7, the foreign material introducing portion 430 can be attached to and detached from the game ball guiding rod 420 by forming them separately from each other. You may make it attach to.

  That is, as shown in the figure, a rib 430b-1 extending along the side plate portion 430b is formed at the upper end of the side plate portion 430b of the foreign material introducing portion 430, and the game ball guide rod 420 is associated with the rib 430b-1. The mating engagement groove 420-1 is formed to the outer end. In such a structure, the foreign material introducing portion 430 is attached to the game ball guiding rod 420 by fitting the rib 430b-1 into the engaging groove 420-1 and sliding the foreign material introducing portion 430 into the engaging ball 420-1.

  In this way, since the foreign substance introduction part 430 can be removed, the foreign substance introduction part 430 can be easily removed and the foreign substance introduction part 430 can be easily cleaned.

  In addition, the foreign material introducing | transducing part 430 may be detachable with respect to members other than the game ball guide rod 420, for example, the board | substrate case 110, a back cover, etc. In other words, the foreign material introduction part 430 only needs to be detachable from any member of the gaming machine.

  In addition, the attachment / detachment form is not limited to the structure shown in FIG. 7, and various forms such as screws, concavity and convexity fitting, and fixing with a hook can be adopted.

  Furthermore, in the present embodiment, the substrate case 110 of the sub-control board is arranged directly below the game ball guide rod 420, but the board case in the present invention is limited to the substrate case 110 of the sub-control board. Instead, for example, a board case in which various boards such as a main control board, a frame relay board, an inverter board, a power board, a launch control board, a payout control board, a CR board, and a production relay board are accommodated can be applied.

  In the present embodiment, in order to prevent such foreign matter from entering the opening of the board case, the foreign matter introduction portion 430 is provided above the opening portion. However, the foreign matter introduction portion 430 is a game ball guide cage. Since foreign matter may be prevented from entering the opening other than the substrate case by introducing foreign matter falling from 420, it is sufficient that the foreign matter introduction portion 430 is provided below the game ball guide rod 420, It does not necessarily have to be located above the opening of the substrate case.

  Then, by guiding the foreign matter to the foreign matter introduction part, it is possible to prevent troubles of electronic parts due to the entry of foreign matter from places other than the opening. Therefore, the present invention is not only from the opening, but from places other than the opening. It is widely applied to prevent foreign matter from entering.

  In the above description, the case where the present invention is applied to the pachinko machine 1 which is one of the gaming machines is described, but the present invention is not limited to this, and a game ball is used as a gaming medium. Any gaming machine that performs a game can be applied to various gaming machines such as various gaming machines installed in a game center.
