Description

  The present invention relates to a pachinko gaming machine in which a sealing means that can easily recognize that a board case for controlling a gaming operation has been broken is attached to the back surface of a gaming board mounting frame.

  Recently, a large display device is mounted on the game board surface, and a movable body that is electrically operated in accordance with the display of the display device is provided to diversify the game and expand the game area. Along with this, the back of the game board is also mechanically complicated, and it becomes difficult to secure the installation space for the board case for controlling the game operation so far, and the board case is attached to the game board mounting frame side. I am doing so.

By the way, in a pachinko gaming machine in which this kind of display device is used, the attached board case is deliberately opened, and a lot of winning balls are deliberately obtained by replacing the back ROM and the duplicated control board. The current situation is that there is no end to cheating. In addition to opening the board case, the board case itself is removed from the game board mounting frame and completely replaced with an illegally processed board case. Therefore, as a countermeasure, for example, a sealing means that can be easily recognized as being broken at the mounting portion of the board case on the back surface of the game board mounting frame is attached and the board case is attached. The sealing means is arranged in a row on the board case side and a plurality of sealed portions arranged on the game board mounting frame side, and is fixed to each sealed portion via a sealing screw as a sealing member. It is comprised from the several sealing part which can do (for example, refer patent document 1).

  Usually, the board case is exchanged as a unit with the game board. However, if the game board is frequently exchanged, the number of sealed parts on the side of the game board mounting frame is required correspondingly. The same number of sealing portions are required for the side sealing portions corresponding to the sealed portions on the game board mounting frame side. For example, as shown in FIG. 12, the first two sealed portions 102a, 102b among the plurality of sealed portions 102a, 102b... Provided in the first sealing means 101 on the game board mounting frame 100 side. Is already used and excised, when the new substrate case 103 is attached, the first two sealed portions 102a and 102b are not excised, so that the corresponding substrate case 103 is removed. Of the plurality of sealed portions 105a, 105b,... Provided in the second sealing means 104 on the side, the first two sealed portions 105a, 105b remain without being used. In such a case, the sealing portions 105a and 105b which are not originally required are formed, and waste is generated. This is because the numbers of the sealed portions 102a, 102b... On the game board mounting frame side 100 and the sealing portions 105a, 105b.

  Accordingly, the present invention has been made to solve the above problems, and provides a pachinko gaming machine in which only a necessary number of sealing portions are provided in the substrate case so as to eliminate waste of the sealing portion on the substrate case side.

  An engagement plate portion 58 having a substantially U-shaped cross section is integrally provided on the outer side of the laterally long frame 54 on the side where the support flanges 56 are provided. The engagement plate portion 58 is fitted into the rail portion 45 so that the second sealing means 53 can move freely along the rail portion 45. As shown in FIG. 6, since the case outer wall 43 of the case cover 26 is fitted into the engagement plate portion 58 having a U-shaped cross section, the second sealing means 53 cannot be removed from the outside. Further, the number of sealing portions 55 on the substrate case 23 side, that is, the second sealing means 53 side is smaller than the number of sealed portions 14 on the game board mounting frame 3 side, that is, the first sealing means 11 side. Is set.

  The pachinko gaming machine P according to the present invention has the above-described configuration, and first the board case 23 is assembled. That is, the electronic component 38 is arranged inside the case cover 26 and in the case outer wall 43 so as to face the through hole 42, and the positioning protrusions 52 are inserted into the small holes 39 as shown in FIG. In this state, the base plate 24 is overlapped with the case cover 26 so as to sandwich the control board 25. At this time, both the case outer walls 43 of the case cover 26 are interposed between the outer side wall 27 and the inner side wall 28 located on opposite sides of the base plate 24, and the case cover 26 is slid as it is. Then, each hook 44 is engaged with the engaging portion 29. At this time, the first sealing means 31 and the second sealing means 46 match. Further, the recessed groove of the engaging plate portion 58 is fitted into the case outer wall 43 of the case cover 26, and the second sealing means 53 is movably attached to the rail portion 45.

  In the matched case cover sealing means B, for example, the sealing pin 51 in the sealing portion 48 (48a) at one end is driven into the pin hole 33 of the sealed portion 34 (34a). Further, as shown in FIG. 8 (b), the lid pin 36 is driven from above and the periphery thereof is sealed with an adhesive. Thereby, the control board 25 is fixed without rattling. Further, the case cover 26 cannot be opened unless the pair of sealed portions 34 and the sealed portion 48 are destroyed.

  The base case 23 assembled in this manner is arranged at the attachment site 10 with the second sealing means 53 facing upward, and the projecting pieces 30 are fitted into the respective guide portions 12 to hold the stoppers 22 to the attachment site 10. Slide upwards along. Then, the second sealing means 53 and the first sealing means 11 are matched. Accordingly, the second sealing means 53 is moved so that the sealing portion 55 is matched with the sealed portion 14 at the end of the first sealing means 11 that is not used. At this time, the stopper 22 at the lower part of the attachment site 10 is released from the pressing, and the claw portion 22 a is engaged with the lower outer edge of the substrate case 23. Thereby, the substrate case 23 is firmly fixed without falling off.

  In the sealing means A for the substrate case, for example, as shown in FIG. 10, the pin hole of the sealed portion 14a is formed in the sealing portion 55a at the end of the sealing portion 55 of the second sealing means 53. A metal sealing pin 59 as a sealing member is driven in until 16 is reached. Further, the lid pin 36 is driven from above and the periphery thereof is sealed with an adhesive. As a result, the board case 23 cannot be removed from the game board mounting frame 3 unless the pair of sealed portions 14a and the sealing portion 55a are destroyed. In addition, the sealing pin 59 may be a sealing screw, for example.

  Therefore, if the case cover 26 of the substrate case 23 that is attached by destroying the sealing means B for the case cover is deliberately opened in order to perform an illegal act, the destroyed trace remains clearly, so In addition, the illegal act of deliberately obtaining a lot of winning balls by replacing the duplicated control board is prevented. Further, when the substrate case sealing means A is destroyed and the substrate case 23 itself is completely replaced with an illegally processed substrate case, the destroyed trace remains clearly, so the substrate case 23 is deliberately replaced. This also prevents fraud.

  On the other hand, a case where the hall side in the business exchanges the game board 2 will be described. The pachinko gaming machine P is used as it is. Therefore, as shown in FIG. 11, the board case 23 that has been attached to the game board mounting frame 3 so far includes the first pair of sealed parts 14a and the sealing part 55a of the sealing means A for the board case. The support hook 13c and the support hook 56 are removed by cutting with a cutting tool such as a nipper. When a new game board 2 is installed, a predetermined number (four) of sealing portions 55 are provided in parallel with the second sealing means 53 in the new board case 23 from the beginning. The stopping means 53 is moved along the rail portion 45, and the first sealing portion 55 a is fixed to the second sealed portion 14 b of the first sealing means 11.

  Temporarily, the second sealing means 53 of the new substrate case 23 is provided with the same number of sealing portions 55 as the number of sealed portions 14 of the first sealing means 11 and the second sealing means 53 moves. If it is fixed, the first sealing portion 55a among the respective sealing portions 55 ends without being used because the corresponding sealed portion 14a has already been cut off.

  As described above, in the pachinko gaming machine P according to the present invention, the number of sealing portions 55 on the board case 23 side is set to be smaller than the number of sealed portions 14 on the game board mounting frame 3 side, and Since each sealing part 55 on the board case 23 side can freely move along the sealed part 14 on the game board mounting frame 3 side, the sealing part 55 of the board case 23 is not wasted.

  In the sealing means A for the substrate case, each sealed portion 14 and each sealed portion 55 are integrally provided on the horizontal flange 13a and the horizontally long frame 54, respectively, but may be separated one by one. Further, the method of attaching the substrate case 23 is not limited to the configuration described in the above embodiment, and it is needless to say that other means may be used.
