The peripheral wall portion 41 of the outer cover member 40 constitutes the outer wall portion of the back cover 3, and the peripheral wall portion 21 of the inner cover member 20 constitutes the inner wall portion of the back cover 3.

  Further, as shown in FIG. 2, the peripheral wall portion 41 of the outer cover member 40 has the front surface size substantially equal to the rear surface size of the flange portion 26 of the inner cover member 20. That is, the thickness of the peripheral wall 41 of the outer cover member 40 (the vertical width in the upper wall and the lower wall and the lateral width in the left and right walls) is the flange of the inner cover member 20. It substantially coincides with the width dimension of the portion 26 (the width dimension in the vertical direction at the top and bottom of the flange portion 26, the width dimension in the left-right direction at the left and right portions of the flange portion 26). In the state where the outer cover member 40 is attached to the inner cover member 20, the flange portion 26 including the fastening portion 28 is sandwiched between the peripheral wall portion 41 of the outer cover member 40 and the game board 2. That is, as shown in FIG. 6, the outer cover member 40 has the front surface of the peripheral wall portion 41 in contact with the head 30 a of the screw 30, and the screw 30 is interposed between the front surface of the peripheral wall portion 41 and the rear surface of the flange portion 26. It is attached to the inner cover member 20 with only a gap for the head 30a. As a result, it is impossible to remove the screw 30 by inserting a tool between the inner cover member 20 and the outer cover member 40 from the outside of the back cover 3 so that the back cover 3 cannot be removed from the game board 2. I have to.

  As shown in FIG. 13, the flange portion 26 may include a hole portion 29 through which the screw 30 is inserted and a head storage portion 37 that stores the head 30 a of the screw 30 in the fastening portion 28. With such a configuration, the outer cover member 40 can be attached to the inner cover member 20 with the front surface of the peripheral wall portion 41 in contact with the rear surface of the flange portion 26 without a gap. Therefore, the room for inserting a tool between the inner cover member 20 and the outer cover member 40 from the outside of the back cover 3 can be substantially completely eliminated.

  After the outer cover member 40 is attached to the inner cover member 20 as shown in FIG. 5, the outer cover member 40 is fastened to the inner cover member 20 in a non-removable manner using the sealing means 50 as shown in FIG. 7. .

  As shown in FIGS. 4 and 7, the holder portion 53 is formed in a substantially cylindrical shape, and has an outer periphery with respect to the front wall portion 24 a of the inner side storage portion 24 and the rear wall portion 24 b of the inner side storage portion 24. The plate-like connecting pieces 55 and 56 are extended from the surface 53 a and are connected and supported by the inner cover member 20.

  Further, as shown in FIG. 7, the holder portion 53 is formed with an insertion hole 54 into which the caulking pin 58 is inserted. The insertion hole 54 is formed so as to penetrate the holder portion 53 in the left-right direction, and in order from the right side, a hexagonal columnar hole-shaped large diameter portion 54a and a cylindrical hole shape having a smaller diameter than the large diameter portion 54a. A diameter portion 54b and a cylindrical hole-shaped small diameter portion 54c smaller in diameter than the medium diameter portion 54b are configured, and a shaft portion 59b of a caulking pin 58 described later is fitted into the small diameter portion 54c.

  The caulking pin 58 is made of metal and includes a pin body 59 and a support ring 60 as shown in FIG. The pin main body 59 includes a disc-shaped head portion 59a on the right end side, and a small-diameter columnar shaft portion 59b extending leftward from the head portion 59a. The shaft portion 59 b is formed so that the outer diameter dimension d is substantially equal to the inner diameter dimension D of the small diameter portion 54 c of the fitting insertion hole 54, and the caulking pin 58 is slidably held by the holder portion 53. An annular groove is provided at the tip 59c of the shaft 59b, and a disc-shaped support ring 60 is fitted therein.

  When the outer cover member 40 is detachably fastened to the inner cover member 20, the support ring 60 is positioned between the holder portion 53 and a fitting portion 63 of the outer side sealing portion 62 described later, and the inner peripheral edge Bites into the outer peripheral surface of the shaft portion 59b, and the caulking pin 58 is restricted from being pulled out.

  As shown in FIG. 7, the outer side sealing portion 62 includes a fitting portion 63 into which the caulking pin 58 is inserted. As shown in FIG. 2, the outer side sealing portion 62 is substantially rectangular provided on the right wall portion of the outer cover member 40. It is disposed in a frame-shaped outer side storage portion 44.

  The fitting portion 63 is formed in a substantially cylindrical shape in accordance with the shape of the holder portion 53, and includes a fitting hole 64 that opens only to the right side and extends to the left side, as shown in FIG. The fitting hole 64 includes a small-diameter portion 64b capable of press-fitting the distal end portion 59c side of the pin main body 59, and a large-diameter portion 64a disposed on the opening periphery of the small-diameter portion 64b and capable of accommodating the support ring 60. Yes. The inner diameter dimension of the small diameter portion 64 b of the fitting hole 64 substantially matches the inner diameter dimension D of the small diameter portion 54 c of the fitting insertion hole 54.

  Further, as shown in FIGS. 4 and 7, the fitting portion 63 is connected from the outer peripheral surface 63 a to the front wall portion 44 a of the outer side storage portion 44 and the rear wall portion 44 b of the outer side storage portion 44. The pieces 65 and 65 are extended, and the top plate portion 66 is extended with respect to the outer side storage portion 44, and is connected to and supported by the outer cover member 40.

  In order to fasten the outer cover member 40 to the inner cover member 20, as shown in FIGS. 7 and 8, the caulking pin 58 is pushed in so as to straddle the fitting portion 63 from the holder portion 53, and the shaft portion 59b. Is arranged so as to straddle the small diameter portion 54 c of the holder portion 53 and the small diameter portion 64 b of the fitting portion 63, and the inner side sealing portion 52 and the outer side sealing portion 62 are fastened. As a result, movement of the outer cover member 40 rearward (in the disengagement direction) is restricted, and the outer cover member 40 is fastened to the inner cover member 20 so as not to be detached.

  In addition, the cap 67 is inserted into the fitting insertion hole 54 of the holder portion 53 from the rear so that the caulking pin 58 cannot be pulled out after the outer cover member 40 is fastened. Thus, unless the inner side sealing portion 52 is broken or the like and the sealing of the back cover 3 (that is, the detachable fastening between the outer cover member 40 and the inner cover member 20) is not released, the outer cover member 40 is removed. It is considered impossible to remove.

  Here, the case where the outer cover member 40 is removed from the inner cover member 20 will be described. When the outer cover member 40 is removed from the inner cover member 20, the two connecting piece portions 55 and 56 extending from the holder portion 53 are divided (see the two-dot chain line in FIG. 8), and the inner side sealing portion 52. After disconnecting, the inner side sealing portion 52 is moved to the right (removal direction) PU (see FIG. 8), and the caulking pin 58 is pulled out from the fitting hole 64. Thereby, sealing with the inner cover member 20 and the outer cover member 40 is cancelled | released. Thereafter, the outer cover member 40 can be removed by removing the presser claw piece 32 from the engagement recess 48 and moving the outer cover member 40 rearward. As described above, when the outer cover member 40 is removed, the inner side sealing portion 52 must be removed, so that the trace of the inner side sealing portion 52 being removed is a trace of the outer cover member 40 being removed. Become. Since the back cover 3 is provided with five sealing means 50, even after the outer cover member 40 is removed, if the unused sealing means 50 is used, the outer cover is again formed. The member 40 can be fastened to the inner cover member 20 so as not to be removed.

  As described above, the pachinko gaming machine 1 according to the first embodiment includes the game board 2 and the board cover 3 that covers the back surface 2 a side of the game board 2, and is provided between the board cover 3 and the game board 2. A main control board 11 for controlling the game is housed in a substantially closed internal space S (see FIGS. 1 and 5) formed in the above. The back cover 3 includes an inner cover member 20 (first member) fastened to the game board 2, an outer cover member 40 (second member) fastened to the inner cover member 20, and an outer cover member 20. Sealing means 50 is provided for fastening the cover member 40 to the inner cover member 20 so as not to be removed. The inner cover member 20 has a fastening portion 28 fastened to the game board 2 using screws 30 (fastening means). The outer cover member 40 cannot be removed from the inner cover member 20 by the sealing means 50 so that contact with the fastening portion 28 from the outside of the back cover 3 is restricted and the fastening by the screw 30 cannot be released. It is concluded to.

  Therefore, according to the pachinko gaming machine 1 of the first embodiment, the outer cover member 40 cannot be removed from the inner cover member 20 unless the sealing means 50 is destroyed. If the outer cover member 40 is not removed, the fastening portion 28 between the back cover 3 and the game board 2 (that is, the fastening portion 28 between the inner cover member 20 and the game board 2) is touched to release the fastening by the screw 30. I can't do it. Therefore, the board back cover 3 cannot be removed from the game board 2 and the main control board 11 cannot be taken out from the internal space S to be modified or exchanged. If the sealing means 50 is destroyed and the outer cover member 40 is removed, a trace of the destruction of the sealing means 50 remains, so that it is possible to immediately discover that an illegal act has been made.

  In particular, in the pachinko gaming machine 1 according to the first embodiment, the outer cover member 40 is fastened to the inner cover member 20 with the fastening portion 28 sandwiched between the game board 2. Therefore, the outer cover member 40 restricts the contact with the fastening portion 28 from the outside of the back cover 3 and the fastening with the screw 30 cannot be released. In other words, since the outer cover member 40 is attached so as to restrict the removal of the screw 30, the outer cover member 40 is obstructed and the screw 30 cannot be removed, and the back cover 3 is attached to the game board. 2 can no longer be removed, and the main control board 11 cannot be taken out from the internal space S to be modified or replaced.

  In the pachinko gaming machine 1 according to the first embodiment, a plurality of sealing means 50 are provided. Therefore, in order to perform maintenance or the like on the main control board 11 housed in the back cover 3, even if the fastening between the outer cover member 40 and the inner cover member 20 is once released, an unused seal is used. Using the stopping means 50, the outer cover member 40 and the inner cover member 20 can be fastened again so that they cannot be detached.

  This has the following merit as compared with the case where the back cover 3 is fastened to the game board 2 so as not to be directly removed. When the back cover 3 is fastened to the game board 2 so that it cannot be directly removed, once the back cover 3 is fastened to the game board 2, it is fastened to take out the main control board 11 stored inside. Although it is necessary to destroy a part of the game board 2 corresponding to the part, it is not realistic to replace the destroyed game board 2 with another game board 2, so that it is not possible to take out the main control board 11 and perform maintenance, etc. It becomes impossible. On the other hand, according to the pachinko gaming machine 1 of the first embodiment, even if the fastening by the sealing means 50 is released, the outer cover member 40 and the inner cover member 20 can be fastened again so that they cannot be detached. Therefore, when maintenance or the like is necessary, the main control board 11 can be taken out for maintenance and inspection. Therefore, it is suitable for the needs of amusement stores and is realistic.

  Further, in the pachinko gaming machine 1 of the first embodiment, an adhesive is applied between the fastening portion 28 and the game board 2. Therefore, the fastening portion 28 of the inner cover member 20 and the game board 2 are firmly fastened without a gap. Therefore, it is possible to make it difficult to cheat by removing a board cover 3 by forcing a jig or the like between the fastening part 28 and the game board 2 from the outside of the board cover 3.

  In the pachinko gaming machine 1 according to the first embodiment, the inner cover member 20 includes a board case mounting seat portion 34 for arranging the main control board 11. Therefore, when the main control board 11 is housed in the back panel cover 3, it is not necessary to provide a separate seat for attaching the board, which is highly convenient.

  In the pachinko gaming machine 1 according to the first embodiment, the back cover 3 is formed of a transparent member. Therefore, since the main control board 11 can be visually recognized from the outside of the back cover 3, the main control board 11 is not taken out from the internal space S, that is, without removing the back cover 3 (outer cover member 40). The main control board 11 can be visually inspected.

  In the pachinko gaming machine 1, since various parts are arranged on the back surface 2a side of the game board 2, it is necessary to secure a sufficient area for storing these parts as the internal space S. Nonetheless, in the gaming machine frame (not shown) to which the game board 2 is attached, there are a large number of devices such as prize ball payout devices and tank rails through which game balls for prize balls pass. There is also a demand for the outer dimensions of the back cover 3 to be as compact as possible so as not to invade. In this regard, in the pachinko gaming machine 1 according to the first embodiment, the fastening portion 28 is disposed outside the peripheral wall portion 41, and the fastening portion 78 has an internal space S as in the pachinko gaming machine 1A according to the second embodiment described later. No invasion. Therefore, in the pachinko gaming machine 1 according to the first embodiment, the board back cover 3 is appropriately designed so that the outer shape of the board back cover 3 avoids a device such as a prize ball payout device disposed in the gaming machine frame. A sufficient area as the internal space S can be ensured without increasing the outer dimensions of 3.

2. Second Embodiment Next, a pachinko gaming machine 1A according to a second embodiment will be described with reference to FIGS. Note that in the pachinko gaming machine 1A of the second embodiment, the same configurations as those of the pachinko gaming machine 1 of the first embodiment are denoted by the same reference numerals as those of the pachinko gaming machine 1 of the first embodiment, and description thereof is omitted. .

  FIG. 9 is a schematic view showing the back side of the game board 2 provided in the pachinko gaming machine 1A according to the second embodiment of the present invention.
