As shown in FIGS. 6, 9, and 10, the main board case 81 includes a first crimping piece 90. The first caulking piece 90 includes a base wall 90a, and rectangular plate-shaped side walls 90b and 90b that project rearward from the left end portion and the right end portion of the base wall 90a and extend in the up-down direction. ing. That is, the shape of the first crimping piece 90 is a U-shape when viewed from above. The 1st crimping piece 90 equips each of the side walls 90b and 90b with the locking piece 90c. The locking pieces 90c, 90c are plate-shaped members whose base ends are connected to the side walls 90b, 90b, respectively, and whose tip ends project between the side walls 90b, 90b. The base ends of the locking pieces 90c, 90c are arranged closer to the front ends (rear sides) of the side walls 90b, 90b than the front ends of the locking pieces 90c, 90c. The locking pieces 90c, 90c can be bent relatively easily in the left-right direction around the base end portion, respectively, but they are hard to bend in the protruding direction (front-rear direction) of the side walls 90b, 90b, and have a predetermined length. Has strength.

As shown in FIGS. 6, 9, and 10, the main board case 81 includes a second caulking piece 91. The second caulking piece 91 protrudes forward from a square plate-shaped base portion 91a extending in the up-down direction and the front surface (the surface on the side of the first caulking piece 90) of the base portion 91a, and also in the up-down direction. A lock plate 91b extending along the lock plate 91b. The lock plate 91b includes a lock hole 91c that penetrates the lock plate 91b in the thickness direction (horizontal direction). In this embodiment, the lock hole 91c has a quadrangular shape.

As shown in FIG. 10, the first caulking piece 90 is inserted into the through hole 85b from the front side (panel case 61 side) opening of the through hole 85b. As described above, since the support portion 85d extends in the vertical direction inside the through hole 85b, the base wall 90a of the first crimping piece 90 is locked to the support portion 85d. In this state, the second caulking piece 91 is inserted into the through hole 88b from the rear opening of the opening of the through hole 88b. In this state, the locking pieces 90c, 90c of the first crimping piece 90 are inserted into the lock holes 91c of the second crimping piece 91, and the locking pieces 90c, 90c and the lock hole 91c are locked. ing.

When the base wall 90a of the first crimping piece 90 contacts the supporting portion 85d, pulling out the second crimping piece 91 from the through hole 88b is restricted. Similarly, the base portion 91a of the second crimping piece 91 is brought into contact with the step portion 88d, whereby the first crimping piece 90 is restricted from being pulled out from the through hole 85b. Then, when the first caulking piece 90 or the second caulking piece 91 is forcibly pulled out, the locking pieces 90c, 90c are destroyed. Therefore, when the caulking pieces 90 and 91 are pulled out and the main board case 81 is opened, the first caulking piece 90 is destroyed, and therefore the caulking portion 85, 88 cannot be fixed. That is, in the main board case 81 of this embodiment, when the base member 82 and the cover member 86 are separated and opened, the caulked portions 85 and 88 can leave traces of opening. The main board case 81 may include a lid member that covers the through holes 85a and 85b and the through holes 88a and 88b. In the main board case 81, by inserting the first caulking piece 90 into the through hole 85a in advance, it is possible to use the spare second caulking piece 91 so that the caulking portions 85 and 88 can be fixed to each other again.

Returning to the description of the cover member 86, as shown in FIG. 6, the cover member 86 is provided on the right end portion 86r side opposite to the left end portion 86l in a pair of right and left penetrating the side wall of the cover member 86. The guide holes 93, 93 are provided. The guide holes 93, 93 are provided in the upper end portion and the lower end portion of the right end portion 86r, respectively. The upper guide hole 93 has the same shape or substantially the same shape as the upper guide rod 84 of the base member 82 when viewed from the right direction. The lower guide hole 93 has the same shape or substantially the same shape as the lower guide rod 84 of the base member 82 when viewed from the right.

As shown in FIG. 9, when the base member 82 and the cover member 86 are assembled, the upper guide rod 84 is inserted through the upper guide hole 93. With the base member 82 and the cover member 86 assembled, the lower guide rod 84 is inserted into the lower guide hole 93. In this embodiment, the guide rods 84, 84 and the guide holes 93, 93 function as a guide portion when the base member 82 and the cover member 86 are assembled.

As shown in FIG. 6, the cover member 86 includes an engaging piece 94 at the right end portion 86r. The shape of the engaging piece 94 is a shape in which the right end portion 86r of the cover member 86 is bent forward and then bent rearward. That is, the engagement piece 94 is bent in a dogleg shape when viewed from above, and can be bent relatively easily in the left-right direction. The tip of the engaging piece 94 is provided with operating portions 94a, 94a protruding rightward and a notch portion 94b sandwiched between the operating portions 94a, 94a. The cover member 86 includes an annular second attachment ring 95 at the right end portion 86r. The second mounting ring 95 projects rightward from the right end portion 86r.

The cover member 86 has an internal terminal hole 96 through which the internal terminal 105 is inserted, in the proximity portion 86b. The thickness of the proximity portion 86b around the internal terminal hole 96 is the same or substantially the same as the thickness of the cover member 86 in other portions. That is, in this embodiment, the main board case 81 does not include a portion which becomes a wall surrounding the internal terminal hole 96, around the internal terminal hole 96. Therefore, the main board case 81 does not have a protective surface that is in contact with or close to the side surface 105a of the internal terminal 105 in the direction orthogonal to the extending direction of the internal terminal 105, except for the thickness of the proximity portion 86b. In a state where the main control board 100 is housed in the main board case 81, the internal terminals 105 project rearward from the rear surface of the proximity portion 86b in the internal terminal holes 96. In this embodiment, the internal terminal 105 is connected to a cable for enabling the transmission of control signals to other boards (sub-control boards 71 and 76).

The cover member 86 has an external terminal hole 97 through which the external terminal 103 is inserted. The shape of the external terminal hole 97 is a quadrangle corresponding to the outer shape of the external terminal 103 when viewed from the rear. The cover member 86 includes a right wall 98a extending rearward from the right edge of the external terminal hole 97, a lower wall 98b extending rearward from the lower edge of the external terminal hole 97, and a left edge of the external terminal hole 97. A left wall 98c extending rearward from the left wall 98c is provided. At the upper edge of the external terminal hole 97, a lower wall 86c of the bulging portion 86a is provided upright rearward. That is, the external terminal hole 97 is surrounded by the walls 86c and 98a to 98c. Therefore, the walls 86c and 98a to 98c form the facing surface 98d that surrounds the external terminal hole 97 and that faces the side surface 103a of the external terminal 103. Thus, the facing surface 98d of the main board case 81 (cover member 86) corresponds to a protective surface extending along the side surface 103a of the external terminal 103 in the direction orthogonal to the extending direction of the external terminal 103. Further, the facing surface 98d of this embodiment is an annular surface surrounding the external terminal 103.

As shown in FIG. 11, the lower wall 86c of the bulging portion 86a includes a first spacer 98e and second spacers 98f, 98f on the surface facing the external terminal 103. The first spacer 98e extends in the left-right direction and is flush with the tip surfaces 98g of the walls 98a to 98c. The second spacers 98f and 98f extend forward from the first spacer 98e (on the side of the main control board 100). The portion of the lower wall 86c where the spacers 98e, 98f, 98f are provided faces the external terminal 103 at these spacers 98e, 98f, 98f. Therefore, a gap S1 is formed between the side surface 103a of the external terminal 103 and the lower wall 86c of the bulging portion 86a by the spacers 98e, 98f, 98f. In this embodiment, the gap S1 allows heat generated at the contact point between the external terminal 103 and the cable (not shown) to escape.

In the state where the main control board 100 is housed in the main board case 81, the tip surfaces 103b of the external terminals 103 project slightly rearward from the tip surfaces 98g of the walls 98a to 98c surrounding the external terminal holes 97. There is. Note that, in FIG. 11, the external terminal 103 is indicated by a two-dot chain line. The tip surface 103b of the external terminal 103 does not protrude rearward of the bulging portion 86a when viewed from above. Therefore, even if the game ball falls from above the main board unit 80, it is difficult for the game ball to contact the external terminal 103.

In this state, the external terminal 103 is close to the walls 86c (spacers 98e, 98f, 98f) and 98a to 98c that surround the external terminal 103. That is, the facing surface 98d is close to the external terminal 103. In addition, a part of the facing surface 98d may be in contact with the side surface 103a of the external terminal 103, or the whole of the facing surface 98d may be in contact with the side surface 103a. The external terminal 103 is substantially entirely buried in the walls 86c, 98a to 98c. That is, the side surface 103a of the external terminal 103 substantially faces the facing surface 98d.

As described above, the cable for connecting to the matching device is inserted into and removed from the external terminal 103. At that time, the external terminals 103 are likely to be loaded along the left-right direction or the vertical direction. However, the main board case 81 of this embodiment is provided with the facing surface 98d in close proximity to the side surface 103a of the external terminal 103. Therefore, even when a load is applied to the external terminal 103 due to the insertion/removal of the cable, the external terminal 103 can be supported by the facing surface 98d to protect the external terminal 103. As described above, in this embodiment, the walls 86c and 98a to 98c form the terminal protection portion 98 that protects the external terminal 103.

As shown in FIG. 6 and FIG. 11, the cover member 86 is provided with a button protection portion 99 that projects rearward from the proximity portion 86b in the proximity portion 86b. The rear surface 99a of the button protection portion 99 does not project rearward of the bulging portion 86a when viewed from above. The button protector 99 has a button hole 99b through which the RWM clear button 104 is inserted. That is, the bulging portion 86a corresponds to a protruding portion that protrudes rearward of the game board 20 beyond the RWM clear button 104 in the upper part of the button hole 99b into which the RWM clear button 104 is inserted. The button protector 99 includes a recess 99c surrounding the button hole 99b. That is, at least a part of the periphery of the button hole 99b is recessed. When the main control board 100 is accommodated in the main board case 81, the RWM clear button 104 does not protrude rearward from the rear surface 99a of the button protection part 99 when viewed from above. Therefore, even if the game ball falls from above the main board unit 80, it is difficult for the game ball to contact the RWM clear button 104.

Next, a state in which the main board unit 80 is assembled to the game board 20 will be described.
As shown in FIGS. 9 and 10, the protruding portion 85c of the main board unit 80 is inserted into the insertion portion 67a from the right side of the left engagement portion 67 (insertion portion 67a) provided in the liquid crystal panel unit 60. There is. Therefore, the main board unit 80 is restricted from moving rearward by the projecting portion 85c of the main board unit 80 and the left engaging portion 67 of the liquid crystal panel unit 60. Since the left engagement portion 67 is provided with the upper wall 67b and the lower wall 67c, the left engagement portion 67 can be guided when the protrusion 85c is inserted into the insertion portion 67a. In this embodiment, the protruding portion 85c corresponds to a mounting portion mounted on the liquid crystal panel unit 60 as the first member.

Further, the engagement piece 94 is inserted into the right engagement portion 66 provided in the liquid crystal panel unit 60. In this state, the right engaging piece 66d of the right engaging portion 66 is engaged so as to fit into the cutout portion 94b of the engaging piece 94. Therefore, the rear board movement of the main board unit 80 is restricted by the right engaging portion 66 of the liquid crystal panel unit 60 and the engaging piece 94 of the liquid crystal panel unit 60.

As described above, since the engaging piece 94 can bend in the left-right direction, the force required when inserting the engaging piece 94 into the right engaging portion 66 can be reduced. Further, by operating the operation portions 94a, 94a of the engagement piece 94 to bend the engagement piece 94 leftward, the engagement between the right engagement piece 66d and the cutout portion 94b can be easily released. .. Further, the lower engaging portion 53 provided on the mounting frame member 50 is engaged with the lower edge portion of the main board case 81 by the lower locking piece 53b. Therefore, the rear board movement of the main board unit 80 is restricted by the lower engagement portion 53 of the mounting frame member 50.

In this way, the main board unit 80 of this embodiment is mounted across the liquid crystal panel unit 60 as the first member and the mounting frame member 50 as the second member. Therefore, for example, even when the main board unit 80 together with the liquid crystal panel unit 60 is to be removed from the pachinko gaming machine 10, the main board unit 80 is also attached to the mounting frame member 50, The board unit 80 cannot be removed from the pachinko gaming machine 10.

Instead of the binding band 110, a caulking structure for fixing the caulking portions 85 and 88 may be adopted as a structure for fixing the main board case 81 and the mounting frame member 50. That is, the main board case 81 may be fixed inseparably without breaking.

A binding band may be used to fix the crimped portions 85 and 88. That is, the base member 82 and the cover member 86 may be fixed inseparably without breaking.
The first engaging portion of the base member 82 and the second engaging portion of the cover member 86 are not limited to the concave portion 83b and the convex portion 87c as in the above embodiment. For example, the base member 82 may be provided with a convex portion and the cover member 86 may be provided with a concave portion.

The protrusion 85c corresponding to the mounting portion may be provided on the second crimp portion 88 of the cover member 86. The left engaging portion 67 to which the protruding portion 85c is attached may be provided on the mounting frame member 50. Even with such a change, it is possible to easily understand the work targets of the work of fixing the crimp portions 85 and 88 to each other and the work of attaching the main board case 81.

The external terminal 103 may be a terminal for connecting an external device different from the matching device. The external terminal 103 may be a terminal for connecting a board (sub control board 71, 76, etc.) different from the main control board 100, or the external terminal 103 may be omitted. If the external terminal 103 is not provided, the terminal protection part 98 may be omitted.

The main control board 100 may include a plurality of internal terminals 105. In this case, the main board case 81 is preferably provided with the same number of holes as the internal terminals 105 for allowing the internal terminals 105 to project to the outside of the main board case 81.

The boards accommodated in the main board case 81 may be the sub-control boards 71 and 76 or may be different boards.
The main board case 81 may contain a plurality of boards. For example, in addition to the main control board 100, the sub control boards 71 and 76 may be housed.

The main board case 81 does not have to include some or all of the walls 86c and 98a to 98c. However, from the viewpoint of protecting the external terminal 103, it is preferable to form at least a part of the walls 86c and 98a to 98c to form a protective surface for protecting the external terminal 103. In other words, the protective surface has only to be formed on at least a part of the periphery of the external terminal hole 97, and need not be a ring surrounding the external terminal 103.

The terminal protection portion 98 may include an annular wall surrounding the external terminal hole 97 or an elliptical annular wall. The button protector 99 can be similarly changed.
-The shapes of the walls 86c and 98a to 98c may be appropriately changed. For example, a protection surface that intermittently surrounds the periphery of the external terminal 103 may be formed by a plurality of columnar portions that project rearward from the periphery of the external terminal hole 97. Further, the walls 86c and 98a to 98c may have a lattice structure.

The main board case 81 may not include the spacers 98e, 98f, 98f.
The main board unit 80 may be attached so as to straddle a plurality of members. For example, the first member may be the first sub-board unit 70 and the second member may be the second sub-board unit 75. Further, the first member may be the game board 20, and the second member may be the mounting frame member 50.

The main board unit 80 may be attached across three or more members. For example, the liquid crystal panel unit 60, the mounting frame member 50, and the first sub-board unit 70 may be mounted over the liquid crystal panel unit 60. In this case, not only the main control board 100 but also the first sub-control board 71 can be prevented from being removed together with other members.

The pachinko gaming machine 10 may be a plasma display type panel or an organic EL type panel instead of the liquid crystal panel 31.
-It may be applied to a slot machine as a game machine. In this case, the slot machine uses medals as a game medium. When the CPU 102 of the main control board 100 receives the operation of the operation lever, the CPU 102 performs the lottery to start the reel rotation. When the CPU 102 receives the operation of the stop button, the CPU 102 stops the reels according to the result of the winning combination lottery and the operation timing of the stop button, and derives the symbol combination (display result). Then, when the symbol combination stopped on the activated line is a symbol combination predetermined as a prize, the CPU 102 gives the player the prize defined in the symbol combination. For example, the prize is re-play (replay game), payout of medals, bonus game grant, ART status grant, and the like.
