That is, the external terminal hole 97 is surrounded by walls 86c, 98a to 98c. Therefore, the walls 86c, 98a to 98c surround the external terminal hole 97 and form a facing surface 98d facing the side surface 103a of the external terminal 103. As described above, 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 a 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 is provided with a first spacer 98e and second spacers 98f and 98f on a surface facing the external terminal 103. The first spacer 98e extends along the left-right direction and is flush with the tip surface 98g of the walls 98a to 98c. The second spacers 98f and 98f extend forward (toward the main control board 100 side) from the first spacer 98e. The portion of the lower wall 86c provided with the spacers 98e, 98f, 98f 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 that may be generated at the contact point between the external terminal 103 and the cable (not shown) to be released.

In a state where the main control board 100 is housed in the main board case 81, the tip surface 103b of the external terminal 103 protrudes slightly rearward from the tip surface 98g of the walls 98a to 98c surrounding the external terminal hole 97. There is. In FIG. 11, the external terminal 103 is shown by a chain double-dashed line. The tip surface 103b of the external terminal 103 does not protrude rearward from 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 come into contact with the external terminal 103.

Further, in this state, the external terminal 103 is in close proximity to the walls 86c (spacers 98e, 98f, 98f) and 98a to 98c surrounding the external terminal 103. That is, the facing surface 98d is close to the external terminal 103. A part of the facing surface 98d may be in contact with the side surface 103a of the external terminal 103, or the entire surface may be in contact with the side surface 103a. Further, substantially the entire external terminal 103 is buried in the walls 86c, 98a to 98c. That is, substantially the entire side surface 103a of the external terminal 103 faces the facing surface 98d.

As described above, a cable for connecting to the collating device is connected to and disconnected from the external terminal 103. At that time, there is a high possibility that a load is applied to the external terminal 103 along the horizontal direction and the vertical direction. However, the main board case 81 of this embodiment is provided with a 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, 98a to 98c form a terminal protection unit 98 that protects the external terminal 103.

As shown in FIGS. 6 and 11, the cover member 86 includes a button protection portion 99 that projects rearward from the proximity portion 86b in the proximity portion 86b.

The button protection unit 99 includes a button hole 99b through which the RWM clear button 104 is inserted. That is, the bulging portion 86a corresponds to a protruding portion protruding rearward of the game board 20 from the RWM clear button 104 at the upper portion of the button hole 99b through which the RWM clear button 104 is inserted. The button protection unit 99 includes a recess 99c that surrounds the button hole 99b. That is, at least a part around the button hole 99b is recessed. In the state where the main control board 100 is housed in the main board case 81, the RWM clear button 104 does not protrude rearward from the rear surface 99a of the button protection unit 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 come into contact with 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 engaging 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 backward by the protruding portion 85c in the main board unit 80 and the left engaging portion 67 in the liquid crystal panel unit 60. Since the left engaging portion 67 is provided with the upper wall 67b and the lower wall 67c, it can be guided when the protruding portion 85c is inserted into the inserting portion 67a. In this embodiment, the protruding portion 85c corresponds to a mounting portion attached to the liquid crystal panel unit 60 as the first member.

Further, the engaging piece 94 is inserted into the right engaging 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 notch portion 94b of the engaging piece 94. Therefore, the main board unit 80 is restricted from moving backward by the right engaging portion 66 in the liquid crystal panel unit 60 and the engaging piece 94 in the liquid crystal panel unit 60.

As described above, since the engaging piece 94 can be bent 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 operating portions 94a and 94a of the engaging piece 94 and bending the engaging piece 94 to the left, the engagement between the right engaging piece 66d and the notch 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 main board unit 80 is restricted from moving backward by the lower engaging portion 53 on the mounting frame member 50.

As described above, the main board unit 80 of this embodiment is attached so as to straddle 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 is to be removed from the pachinko gaming machine 10 together with the liquid crystal panel unit 60, 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.

The work of accommodating in can be easily performed. Therefore, workability when the main control board 100 is housed in the main board case 81 can be improved.

(3) According to this embodiment, the fixing portions (caulking portions 85 and 88) of the base member 82 and the cover member 86 are fixed to each other inseparably unless they are broken, so that the main substrate case 81 When opened, it is possible to leave a trace of it. Therefore, even if the regular main control board 100 is replaced with an unauthorized board, it is possible to easily determine whether or not the replacement is present. Therefore, security can be improved.

(4) According to this embodiment, the protruding portion 85c attached to the liquid crystal panel unit 60 is provided in the first caulking portion 85 for fixing the base member 82 and the cover member 86. Therefore, it is possible to easily understand the work target for the work of fixing the crimped portions 85 and 88 to each other and the work of attaching the main board case 81.

(5) According to this embodiment, since the main board case 81 accommodating the main control board 100 is mounted so as to straddle the liquid crystal panel unit 60 and the mounting frame member 50, each liquid crystal panel unit 60 is attached. It is difficult to remove the main control board 100 or remove the main control board 100 together with the mounting frame member 50. Then, since the binding band 110 for fixing the mounting frame member 50 and the main board case 81 is configured so that the main board case 81 cannot be removed without breaking, the main board case 81 is removed. Sometimes it becomes possible to leave a trace of it. Therefore, even if the regular main control board 100 is replaced with an unauthorized board, it is possible to easily determine whether or not the replacement is present. Therefore, it is possible to suppress unauthorized replacement of the substrate and improve security.

(6) According to this embodiment, the external terminal 103 has a facing surface 98d as a protective surface extending along the side surface of the external terminal 103 when the external terminal 103 is about to tilt or the external terminal 103 is tilted. Supported by. Therefore, the external terminal 103 can be protected.

-The main board unit 80 may be mounted 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 straddled and mounted. 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 winning combination lottery is performed and the rotation of the reel is started. 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 combination of symbols (display result). Then, when the combination of symbols stopped on the effective line is a combination of symbols predetermined to give a prize, the CPU 102 grants the player a prize defined for the combination of the symbols. For example, prizes include replay games, medal payouts, bonus games, and ART status.
