  When the base wall 90a of the first caulking piece 90 abuts on the support portion 85d, the second caulking piece 91 is restricted from being pulled out from the through hole 88b. Similarly, when the base portion 91a of the second caulking piece 91 contacts the step portion 88d, the first caulking piece 90 is restricted from being pulled out from the through hole 85b. And when the 1st crimping piece 90 and the 2nd crimping piece 91 are pulled out forcibly, the locking pieces 90c and 90c are destroyed. For this reason, when the main caulking pieces 90 and 91 are pulled out and the main board case 81 is opened, the first caulking pieces 90 are destroyed. 88 cannot be fixed. That is, the main board case 81 of this embodiment can leave an opening trace in the crimping portions 85 and 88 when the base member 82 and the cover member 86 are separated and opened. 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. Note that the main board case 81 is configured such that the first caulking piece 90 is inserted into the through hole 85a in advance, so that the caulking portions 85 and 88 can be fixed again using the spare second caulking piece 91. Good.

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

  As shown in FIG. 9, in the state where the base member 82 and the cover member 86 are assembled, the upper guide bar 84 is inserted through the upper guide hole 93. In a state where the base member 82 and the cover member 86 are assembled, the lower guide rod 84 is inserted through the lower guide hole 93. In this embodiment, the guide rods 84 and 84 and the guide holes 93 and 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 engagement piece 94 at the right end 86r. The shape of the engagement piece 94 is a shape bent from the right end portion 86r of the cover member 86 to the front and then to the rear. 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 distal end portion of the engagement piece 94 is provided with operation portions 94a and 94a projecting rightward, and a notch portion 94b sandwiched between the operation portions 94a and 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 includes 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 as 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 that 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 accommodated in the main board case 81, the internal terminal 105 protrudes rearward from the rear surface of the proximity portion 86b in the internal terminal hole 96. In this embodiment, the internal terminal 105 is connected to a cable for connecting to other boards (sub-control boards 71 and 76) so that control signals can be transmitted.

  The cover member 86 includes 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 external 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 rear side. At the upper edge of the external terminal hole 97, a lower wall 86c of the bulging portion 86a is erected rearward. That is, the external terminal hole 97 is surrounded by the walls 86c and 98a to 98c. Therefore, the walls 86 c and 98 a to 98 c form a facing surface 98 d that surrounds the external terminal hole 97 and faces the side surface 103 a of the external terminal 103. Thus, the opposing 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 opposing surface 98d of this embodiment is an annular surface surrounding the external terminal 103.

  As shown in FIG. 11, the lower wall 86 c of the bulging portion 86 a includes a first spacer 98 e and second spacers 98 f and 98 f on the surface facing the external terminal 103. The first spacer 98e extends along the left-right direction and is flush with the front end surfaces 98g of the walls 98a to 98c. The second spacers 98f, 98f extend from the first spacer 98e toward the front (main control board 100 side). The portions of the lower wall 86c where the spacers 98e, 98f, 98f are provided are opposed to the external terminals 103 in the 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, and 98f. In this embodiment, the gap S <b> 1 can release heat that may be generated at the contact point between the external terminal 103 and a cable (not shown).

  In a state where the main control board 100 is accommodated in the main board case 81, the front end surface 103b of the external terminal 103 slightly protrudes rearward from the front end surfaces 98g of the walls 98a to 98c surrounding the external terminal hole 97. Yes. 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 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 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 surrounding the external terminal 103. That is, the facing surface 98 d is close to the external terminal 103. Note that 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, the external terminal 103 is almost entirely buried in the walls 86c, 98a to 98c. That is, the entire side surface 103a of the external terminal 103 is opposed to the opposing surface 98d.

  As described above, a cable for connecting to the verification device is inserted into and removed 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 or the vertical direction. However, the main board case 81 of this embodiment is provided with a facing surface 98d in the vicinity of the side surface 103a of the external terminal 103. Therefore, even when a load is applied to the external terminal 103 as the cable is inserted and removed, the external terminal 103 can be supported by the facing surface 98d and the external terminal 103 can be protected. As described above, in this embodiment, the walls 86 c and 98 a to 98 c constitute the 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 part 99 that protrudes rearward from the proximity part 86 b in the proximity part 86 b. The rear surface 99a of the button protection part 99 does not protrude rearward from the bulging part 86a when viewed from above. The button protector 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 that protrudes rearward of the game board 20 from the RWM clear button 104 above the button hole 99b through which the RWM clear button 104 is inserted. The button protection part 99 includes a recess 99c that surrounds the button hole 99b. That is, at least a part of the periphery of the button hole 99b is recessed. In a state where 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 protector 99 when viewed from above. Therefore, even if the game ball falls from above the main board unit 80, the game ball is difficult to contact the RWM clear button 104.

Next, a state where 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 85 c of the main board unit 80 is inserted into the insertion portion 67 a from the right side of the left engagement portion 67 (insertion portion 67 a) provided in the liquid crystal panel unit 60. Yes. Accordingly, the rear movement of the main board unit 80 is restricted by the protrusion 85 c in the main board unit 80 and the left engagement part 67 in the liquid crystal panel unit 60. Since the left engagement 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 insertion portion 67a. In this embodiment, the protrusion 85c corresponds to an attachment portion attached to the liquid crystal panel unit 60 as the first member.

  Further, the engagement piece 94 is inserted into a right engagement portion 66 provided in the liquid crystal panel unit 60. In this state, the right engagement piece 66d of the right engagement portion 66 is engaged so as to fit into the notch portion 94b of the engagement piece 94. Therefore, the rear movement of the main board unit 80 is restricted 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 engagement piece 94 can be bent in the left-right direction, the force required when the engagement piece 94 is inserted into the right engagement portion 66 can be reduced. Further, by operating the operation portions 94a and 94a of the engagement piece 94 to bend the engagement piece 94 leftward, the engagement between the right engagement piece 66d and the notch portion 94b can be easily released. . Further, the lower engagement 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 movement of the main board unit 80 is restricted by the lower engagement portion 53 in the mounting frame member 50.

  Thus, the main board unit 80 of this embodiment is attached over 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.

  3A and 3B, the first mounting ring 55 of the mounting frame member 50 and the second mounting ring 95 of the main board unit 80 (cover member 86) are a binding band. 110 is fixed. Therefore, when removing the main board unit 80 from the mounting frame member 50, the binding band 110 needs to be cut. That is, the main board unit 80 and the mounting frame member 50 are fixed so as not to be separated without breaking. Therefore, in this embodiment, when the board unit 80 is removed from the mounting frame member 50, it is possible to leave a trace of removal in the attachment rings 55 and 95. In this embodiment, the binding band 110 corresponds to a fixing portion that fixes the mounting frame member 50 and the main board case 81.

Therefore, the pachinko gaming machine 10 of this embodiment has the following effects.
(1) According to this embodiment, since the main board case 81 that accommodates the main control board 100 is attached across the liquid crystal panel unit 60 and the mounting frame member 50, the liquid crystal panel unit 60. It is difficult to remove the main control board 100 or remove the main control board 100 together with the mounting frame member 50. Therefore, it is possible to suppress unauthorized substrate replacement and improve security.

  (2) According to this embodiment, the main control board 100 is connected to the main board case 81 by engaging the engaging parts (concave part 83b and convex part 87c) of the base member 82 and the cover member 86 with each other. The work to be accommodated in can be easily performed. Therefore, workability when the main control board 100 is accommodated in the main board case 81 can be improved.

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

  (4) According to this embodiment, the protruding portion 85 c attached to the liquid crystal panel unit 60 is provided in the first caulking portion 85 that fixes the base member 82 and the cover member 86. For this reason, the work target can be easily understood for the work of fixing the caulking portions 85 and 88 and the work of attaching the main board case 81.

  (5) According to this embodiment, since the main board case 81 that accommodates the main control board 100 is mounted across the liquid crystal panel unit 60 and the mounting frame member 50, the entire liquid crystal panel unit 60 is provided. It is difficult to remove the main control board 100 or remove the main control board 100 together with the mounting frame member 50. Since the binding band 110 that fixes the mounting frame member 50 and the main board case 81 is configured such 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. For this reason, even if the regular main control board 100 is replaced with an unauthorized board, it is possible to easily determine whether or not the board is replaced. Therefore, it is possible to suppress unauthorized substrate replacement 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 when the external terminal 103 is tilted. Supported by. Therefore, the external terminal 103 can be protected.

(7) According to this embodiment, since the side surface 103a of the external terminal 103 is surrounded by the opposing surface 98d, the external terminal 103 can be protected in any direction.
(8) According to this embodiment, the facing surface 98d is close to or in contact with the side surface 103a of the external terminal 103. Therefore, the external terminal 103 can be prevented from being largely inclined and can be further protected.

  (9) According to this embodiment, the main board case 81 includes the button hole 99b, and the periphery of the button hole 99b is recessed by the recess 99c. Therefore, contact between the RWM clear button 104 and the game ball can be suppressed. Therefore, it is possible to suppress the occurrence of erroneous operations.

  (10) According to this embodiment, the main board case 81 includes the bulging portion 86a that protrudes to the rear of the game board 20 from the RWM clear button 104 at the upper part of the button hole 99b. Therefore, it becomes difficult for a game ball falling behind the game board 20 to contact the RWM clear button 104. Therefore, it is possible to suppress the occurrence of erroneous operations.

  (11) According to this embodiment, with respect to the internal terminal 105 that is assumed to have relatively few cable removals, it is possible to secure a work space by not providing a protective surface and to facilitate connection work.

  (12) According to this embodiment, the liquid crystal panel unit 60 is sized to cover most of the back surface of the game board 20. Therefore, if the main board unit 80 is to be attached only to the mounting frame member 50, the degree of freedom in designing the arrangement relationship between the main board unit 80 and the liquid crystal panel unit 60 is reduced. However, in this embodiment, the degree of freedom in design is improved by attaching the main board unit 80 across the mounting frame member 50 and the liquid crystal panel unit 60.

  (13) According to this embodiment, the main board unit 80 protrudes most rearward on the rear side of the game board 20 due to being attached to the rear side of the liquid crystal panel unit 60. Therefore, there is a high possibility that a game ball falling on the rear side of the game board 20 will come into contact. However, in this embodiment, the contact between the game ball and the external terminal 103 or the RWM clear button 104 can be suppressed and protected by the bulging portion 86a.

For example, the embodiment described above may be changed to another embodiment as follows.
As shown in FIG. 12, the main board case 81 may include a right wall 151, a lower wall 152, and a left wall 153 that surround the button protection unit 99. That is, the button protection part 99 may be surrounded by the walls 86c and 151-153. In this case, the right wall 151 may also be used as the left wall 98c surrounding the external terminal 103. According to this, it can suppress that the game ball which falls the back side of the game board 20 contacts the RWM clear button 104. FIG. Further, the upper surface 152a of the lower wall 152 may be an inclined surface that falls downward as it goes rearward. According to this, even when a game ball falling on the rear side of the game board 20 comes into contact with the lower wall 152, the game ball can be guided backward (opposite to the RWM clear button 104). it can. Therefore, it is possible to suppress the occurrence of erroneous operations.

-The upper wall of the terminal protection part 98 and the button protection part 99 may not be combined with the lower wall 86c of the bulging part 86a.
The operation member protected by the button protection unit 99 may be a volume control knob. The button protection unit 99 may protect a plurality of operation members.

The main control board 100 may not include the RWM clear button 104. In this case, the button protection unit 99 may be omitted.
The terminal protection unit 98 may protect a plurality of terminals.

  The first mounting ring 55 of the mounting frame member 50 and the second mounting ring 95 of the main board unit 80 may be close to each other or may be adjacent to each other so as to come into contact with each other. According to this, the play between the mounting frame member 50 and the main board unit 80 can be eliminated and fixed firmly.

  The first attachment ring 55 may be provided in the liquid crystal panel unit 60. The first mounting ring 55 may be provided in both the mounting frame member 50 and the liquid crystal panel unit 60, and the two second mounting rings 95 may be provided in the main board case 81. According to this, the main board case 81 can be fixed to both the mounting frame member 50 and the panel case 61 in an inseparable manner without breaking.

  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 substrate case 81 may be fixed so as not to be separated without being destroyed.

A binding band may be used for fixing the crimping portions 85 and 88. That is, the base member 82 and the cover member 86 may be fixed so as not to be separated without breaking.
-The 1st engaging part of the base member 82 and the 2nd engaging part of the cover member 86 are not restricted to the recessed part 83b and the convex part 87c like the said Example. 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 protruding portion 85 c corresponding to the attachment portion may be provided on the second caulking portion 88 of the cover member 86. The left engaging portion 67 to which the protruding portion 85 c is attached may be provided on the mounting frame member 50. Even if it changes in this way, a work object can be easily understood about the work which fixes caulking parts 85 and 88, and the work which attaches main board case 81.

  The external terminal 103 may be a terminal for connecting an external device different from the verification device. The external terminal 103 may be a terminal for connecting a board (such as the sub-control boards 71 and 76) different from the main control board 100, and the external terminal 103 may be omitted. If the external terminal 103 is not provided, the terminal protection unit 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 causing the internal terminals 105 to protrude outside the main board case 81.

-The board | substrate accommodated in the main board | substrate case 81 may be the sub control boards 71 and 76, and may be a board | substrate different from this.
The main substrate case 81 may accommodate a plurality of substrates. For example, in addition to the main control board 100, the sub control boards 71 and 76 may be accommodated.

  The main board case 81 may not 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 a protective surface for protecting the external terminal 103 by providing at least a part of the walls 86c, 98a to 98c. In other words, the protective surface only needs to be formed on at least a part of the periphery of the external terminal hole 97, and does not have to be in an annular shape surrounding the external terminal 103.

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

The main board case 81 may not include the spacers 98e, 98f, and 98f.
-The main board unit 80 should just be attached ranging over several 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 attached. 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 gaming machine. In this case, the slot machine uses medals as game media. When the CPU 102 of the main control board 100 accepts the operation of the operation lever, it performs a role lottery and starts the rotation of the reels. When receiving the operation of the stop button, the CPU 102 stops the reel according to the result of the combination lottery and the operation timing of the stop button, and derives a combination of symbols (display result). When the combination of symbols stopped on the active line is a combination of symbols that is predetermined as award, the CPU 102 gives the player the award determined for the combination of symbols. For example, the prize includes replay (replay game), payout of medals, bonus game, and ART state.

The following technical idea can be understood from the above-described embodiment.
(A) It includes another substrate that is separate from the substrate, the substrate includes an internal terminal for connecting to the other substrate, and the case is in a direction orthogonal to the extending direction of the internal terminal. There is no protective surface in contact with or close to the side surface of the internal terminal.

  (B) a game board, a first member attached to the rear side of the game board, a second member attached to the rear side of the game board, a board, and a case housing the board; The case is attached to the first member and the second member. In recent years, fraudulent acts have become more sophisticated, and it is assumed that the substrate will be removed together with the case. For this reason, it is expected to further improve the security of the gaming machine. According to this technical concept, security can be improved.
