The upper and lower first side wall portions 101 face each other in a range of ½ or more of the front-rear width of the substrate case 71 in a state where the front plate 79 of the substrate case 71 is in contact with the installation surface 93. It is provided and is configured to enhance the support stability of the substrate case 71.

  Then, as shown in FIGS. 12 and 13, the first side protrudes toward the substrate case 71 on the facing surface 101 a of the upper and lower first side wall portions 101 facing the back plate 76 of the substrate case 71. A side regulating portion 102 is formed, and the back plate 76 of the substrate case 71 is brought into contact with the first side regulating portion 102, so that the substrate case 71 moves to the left edge portion side of the installation region 90a. Being regulated. The first side restricting portion 102 is formed to extend linearly along the protruding direction (front-rear direction) of the first side wall portion 101, and a plurality of the first side restricting portions 102 are provided so as to be separated from each other in the vertical direction. Yes. In the embodiment, four first side restriction portions 102 are provided on the upper first side wall portion 101, and three first side restriction portions 102 are provided on the lower first side wall portion 101. In addition, as shown in FIG. 13, each first side regulating portion 102 is connected to the installation surface 93 and contacts the back plate 76 of the substrate case 71 held in the installation area 90a. The first side which is inclined so as to be separated from the substrate case 71 (the back plate 76) which is connected to the direction regulation surface 102a and the rear end portion of the first side regulation surface 102a and which is held in the installation region 90a toward the rear. A direction guide surface 102b (guide surface) is provided. That is, when the substrate case 71 is moved from the rear with respect to the installation region 90a, the position where the back plate 76 of the substrate case 71 contacts the first side regulating surface 102a along the first side guide surface 102b. Can be guided to.

  As shown in FIGS. 13 and 15, the opposing surface 101 a facing the back plate 76 of the substrate case 71 in the upper and lower first side wall portions 101 is a rear end (protruding front end side) of the first side wall portion 101. It is formed in an inclined shape so as to move away from the substrate case 71 as it goes toward the center. That is, each first side wall portion in a state in which the back plate 76 of the substrate case 71 is in contact with the first side regulating portion 102 (first side regulating surface 102a) formed on the upper and lower first side wall portions 101. The rear end portion 101 is greatly separated from the back plate 76 of the substrate case 71 so that the visibility of the back side of the substrate case 71 is enhanced. In other words, each of the first side regulating portions 102 protrudes from the opposing surface 101a of the first side wall portion 101 as it goes from the rear end portion of the first side wall portion 101 to the front end portion (installation surface 93 side). Since it is formed in a triangular plate shape whose height gradually decreases, the rigidity of the first side regulating portion 102 can be increased, and the support stability of the substrate case 71 can be improved. Here, S1 formed between the opposing surface 101a of the first side wall 101 and the back plate 76 of the substrate case 71 is a gap S2 defined between the substrate case 71 and the spherical path unit 132. The back plate 76 of the board case 71 can be visually recognized from the rear side of the game board 20 through the gaps S1 and S2.

  As shown in FIG. 12, the outer side surface 101b located on the opposite side to the facing surface 101a in the upper and lower first side wall portions 101 is inclined closer to the installation region 90a toward the protruding front end side of the first side wall portion 101. It is formed in a shape. That is, the upper and lower first side wall portions 101 are formed in a tapered shape from the front end side serving as the projecting proximal end toward the rear end serving as the projecting distal end, and have a width on the projecting proximal end side. By securing a large value, the rigidity of the first side wall 101 is increased.

(About the 2nd side regulation part 105)
As shown in FIGS. 12, 13, and 14, the installation member 50 has a right side of the installation region 90 a in the left-right direction perpendicular to the facing direction (vertical direction) of the engagement recess 95 and the first upper regulating portion 98. A second side wall portion 104 that protrudes rearward and faces the surface plate 75 of the substrate case 71 is formed at the edge portion (the other edge portion). The second side regulating portion 105 is formed on the second side wall portion 104. Here, the second side wall portion 104 is formed to face a region between the upper and lower first side wall portions 101 located with the substrate case 71 (installation region 90a) interposed therebetween. That is, when the substrate case 71 is held by the holding mechanism unit 90, the first side wall portion 101 and the second side wall portion 104 are opposed to the front surface plate 75 and the back surface plate 76 of the substrate case 71. Thus, the fluidity of the air around the substrate case 71 is enhanced. Further, the second side wall portion 104 is provided at a position facing the lower half of the surface plate 75 in the substrate case 71 and a vertical width in a state where the substrate case 71 is attached to the installation region 90a (FIG. 5). reference). That is, the second side wall portion 104 is formed to face the lower half portion of the surface plate 75 where the through hole 75a is hardly provided.

  As shown in FIGS. 8, 12, and 13, the second side surface protrudes toward the substrate case 71 on the facing surface 104 a of the second side wall 104 facing the surface plate 75 of the substrate case 71. A restricting portion 105 is formed, and the movement of the front substrate case 71 to the right edge portion side of the installation region 90a is restricted by the surface plate 75 of the substrate case 71 coming into contact with the second side restricting portion 105. It has come to be. The second side restricting portion 105 is formed to extend linearly along the protruding direction (front-rear direction) of the second side wall portion 104, and a plurality of second side restricting portions 105 are provided so as to be separated from each other in the vertical direction. Yes. In the embodiment, four first side regulating portions 102 are provided on the upper second side wall portion 104. Further, a reinforcing rib extending in the front-rear direction on the outer surface 104b located on the opposite side of the opposing surface 104a in the second side wall portion 104 at a position corresponding to the position where the second side regulating portion 105 is formed. 104c is formed to prevent the second side wall portion 104 from being damaged when the substrate case 71 comes into contact with the second side regulating portion 105.

  The protruding height of the second side wall portion 104 with respect to the rear surface of the game board 20 is the same as that of the upper and lower sides with respect to the rear surface of the game board 20 as shown in FIGS. The first side wall portion 101 is formed so as to be lower than the rearward protruding height. That is, the first side wall portion 101 and the second side wall portion 104 are formed to have different protruding heights with respect to the rear surface of the game board 20. The second side wall portion 104 is provided so as to face within a range of ½ of the front-rear width of the substrate case 71 with the front plate 79 of the substrate case 71 in contact with the installation surface 93. In addition, the support stability of the substrate case 71 is increased.

(About elastic locking piece 107)
As shown in FIGS. 7 and 14 to 16, the installation member 50 can be elastically deformed at a position facing the surface plate 75 of the substrate case 71 in the direction of approaching and separating from the substrate case 71. An elastic locking piece 107 is formed. The elastic locking piece 107 includes a long-plate-shaped locking piece main body 108 extending rearward from a rear end portion of the installation member 50 (third frame body portion 50c), and the substrate on the locking piece main body 108. And an engaging claw 109 provided so as to protrude toward the case 71 (installation area 90a) and detachably engageable with the stopper projection 84, and the front plate 79 of the substrate case 71 is disposed on the installation surface. 93 is configured to restrict the rearward movement of the substrate case 71 by engaging the stopper claw 109 with the engaging claw 109 when it is brought into contact with 93. In addition, an operation piece 110 is provided at the rear end of the elastic locking piece 107 so as to be separated from the installation area 90a toward the rear, and the elastic locking piece 107 is operated by operating the operation piece 110. By being elastically deformed, the engagement state between the engagement claw 109 and the stopper projection 84 can be released.

  As shown in FIG. 16, the engaging claw 109 includes a protruding portion 109a extending along the upper and lower end edges of the locking piece main body 108 and a protruding portion facing from the rear end portion of the upper and lower protruding portion 109a. It is formed in a vertically symmetrical bowl shape from the locking piece 109b extending upward or downward toward the portion 109a. When the front plate 79 of the plate case is brought into contact with the installation surface 93, the upper and lower The stopper projection 84 faces the locking region surrounded by the protrusion 109a and the locking piece 109b, and the rear end of the stopper protruding portion 84 engages with the front end of the locking piece 109b. It is designed to regulate the rearward movement.

  Here, the separation distance W7 from the engaging claw 109 of the elastic locking piece 107 to the end of the first side regulating portion 102 formed on the first side wall portion 101 is (see FIG. 15C). The left and right width dimensions W3 of the substrate case 71 (see FIG. 11C) are formed to be narrower. That is, the elastic locking piece 107 is configured not to be completely elastically restored while the substrate case 71 is held by the holding mechanism 90, and the engagement claw 109 presses the surface plate 75 of the substrate case 71. Thus, the engagement state between the engagement claw 109 and the stopper projection 84 can be reliably maintained.

  As shown in FIGS. 15 and 16, a working wall 111 is formed at the rear end of the elastic locking piece 107 so as to be closer to the installation area 90a toward the front. The action wall 111 and the operation piece 110 are configured to form a continuous inclined surface. When the substrate case 71 is attached to the installation area 90a, the stopper wall 84 (first rib 84a) is in contact with the working wall 111, and the stopper wall 84 is brought into contact with the working wall 111. Thus, the elastic locking piece 107 can be elastically deformed. The locking piece body 108 of the elastic locking piece 107 is formed with a rail-shaped guide portion 112 extending rearward from the opposed ends of the pair of upper and lower locking pieces 109b toward the working wall 111. Yes. In addition, the guide portion 112 attaches the board case 71 in an inclined posture in which the lower protrusion 82 is inserted into the engagement recess 95 to the mounting position around the engagement position between the lower protrusion 82 and the engagement recess 95. The stopper projection 84 is provided so as to be positioned on a moving path along which the stopper projection 84 moves. That is, when the board case 71 is attached to the installation region 90a, the elastic locking piece 107 elastically deformed with the contact of the stopper projection 84 is elastically restored, and the guide portion 112 and the stopper projection 84 At the timing when the front plate 79 of the substrate case 71 contacts the installation surface 93, while allowing the stopper projection 84 to move to the engagement position with the engagement claw 109. When the stopper projection 84 moves to the front end side of the engagement claw 109 and the elastic locking piece 107 is elastically restored, the stopper projection 84 and the engagement claw 109 are naturally engaged. The spacing between the upper and lower guide portions 112 is formed so as to substantially match the spacing between the upper and lower first ribs 84 a in the stopper projection 84.

(Operation of Example)
Next, the operation of the pachinko machine 10 configured as described above will be described.

  When installing the substrate case 71 (overall control device 70) with respect to the holding mechanism 90, the first side wall 101 (first side regulating part 102) and the second side wall 104 (second side regulating) The substrate case 71 is inserted from the lower protrusion 82 between the portions 105). At this time, since the first side wall portion 101 is protruded far rearward than the second side wall portion 104, the back plate 76 of the substrate case 71 in the inclined posture is used as the first side regulating portion 102 of the first side wall portion 101. (See M1 in FIG. 17), the board case 71 is positioned at a position where the board case 71 can be inserted between the first side regulating part 102 and the second side regulating part 105 from the rear. Can be combined. Therefore, the substrate case 71 can be inserted from behind only by bringing the substrate case 71 brought into contact with the first side restriction portion 102 close to the installation surface 93 along the first side restriction. At this time, the first side restricting portion 102 is formed with the first side guide surface 102b and the second side restricting portion 105 is formed with the second side guide surface 105b. Even if the board case 71 is displaced left and right from a position where it can be inserted between the second side regulating part 105 and the second side regulating part 105, the posture of the board case 71 is corrected by the first side guiding surface 102b and the second side guiding surface 105b. Thus, it can be easily inserted between the first side restricting portion 102 (first side restricting surface 102a) and the second side restricting portion 105 (second side restricting surface 105a).

  Then, the substrate case 71 is moved downward with the lower protrusion 82 of the substrate case 71 inserted in an inclined posture between the first sidewall portion 101 and the second sidewall portion 104 in contact with the installation surface 93. As a result, the lower protrusion 82 is inserted into the engagement recess 95 through the engagement port 95 a of the engagement recess 95. At this time, since the retracting portion 95b is formed in the engaging recess 95, the substrate case 71 can be inserted in an inclined posture. Further, since the left and right opening width (W5) of the engagement port 95a in the engagement recess 95 is larger than the left and right width (W3) of the lower protrusion 82 of the substrate case 71, the lower protrusion 82 is engaged. It can be easily inserted into the recess 95. Then, the front plate 79 of the board case 71 is brought into contact with the installation surface 93 by raising the board case 71 from the inclined position to the mounting position with the lower protrusion 82 engaged with the engaging recess 95 as a fulcrum. When contacting, the stopper protrusion 84 of the substrate case 71 engages with the elastic locking piece 107, and the substrate case 71 is held by the holding mechanism 90.

  Here, since the first upper guide portion 98b is formed on the first upper restricting portion 98 provided on the upper wall portion 97 facing the upper protrusion 83 of the substrate case 71, it is attached from the inclined posture. Even if the substrate case 71 is displaced upward when it is rotated to the posture, the posture of the substrate case 71 is corrected by the first upper guide surface 98b, and the first upper restriction surface in the first upper restriction portion 98. The upper protrusion 83 of the substrate case 71 can be guided to 98a. Further, since the second upper restricting portion 99 is formed on the upper wall portion 97 at a position sandwiching the upper protrusion 83, and the second upper guide surface 99b is formed on the second upper restricting portion 99. Even when the upper protrusion 83 of the substrate case 71 is shifted to the left and right when the substrate case 71 is rotated from the inclined posture to the mounting posture, the second upper guide surface 99b corrects the posture of the substrate case 71 to the second position. It can guide so that the side of upper projection 83 may contact the 2nd upper regulation surface 99a in upper regulation part 99.

  Further, when the substrate case 71 is rotated so as to change from the inclined posture to the mounting posture, it contacts the action wall 111 of the elastic locking piece 107 located on the movement locus of the stopper projection 84. Accordingly, when the substrate case 71 is displaced to the mounting posture in a state where the stopper protrusion 84 is in contact with the action wall 111 of the elastic locking piece 107, the action wall 111 is pressed by the stopper protrusion 84 and the elastic locking piece 107. The stopper projection 84 is elastically locked after the stopper projection 84 passes through the contact position with the working wall 111 and moves along the guide portion 112. By being guided to the locking region of the piece 107, the locking piece main body 108 is elastically restored, whereby the stopper projection 84 is locked by the elastic locking piece 107. In this way, the stopper projection 84 can be naturally engaged with the elastic locking piece 107 simply by rotating the substrate case 71 so as to change from the inclined posture to the mounting posture. Further, the separation distance W7 from the engagement claw 109 of the elastic locking piece 107 to the first lateral restriction portion 102 is formed to be narrower than the left and right width dimension W3 of the substrate case 71, and the elastic elasticity is restored. Since the locking piece 107 is configured to press the surface plate 75 of the substrate case 71, it is possible to prevent the engagement state between the stopper projection 84 and the elastic locking piece 107 from being loosened. The holding mechanism 90 can stably hold it.

  Then, a holding mechanism 90 is provided so that the overall control device 70 (board case 71) can be held in a posture in which the surface of the circuit board 72 intersects the rear surface of the game board 20, and the overall held by the holding mechanism 90 is provided. A positional relationship in which the control device 70 and the symbol display device 18 held in the effect device holding unit overlap in the direction along the rear surface of the game board 20 (specifically, a positional relationship in which they overlap in the left and right directions. The end positions are substantially the same). Therefore, compared with the case where the overall control device 70 is installed behind the symbol display device 18, the size of the entire game board 20 in the front-rear direction can be suppressed. Further, since it is not necessary to remove the overall control device 70 when removing the symbol display device 18, the inspection and replacement work relating to the symbol display device 18 can be simplified.

  Further, an engagement recess 95 that engages with the lower protrusion 82 of the substrate case 71 in the overall control device 70 and a first contact that is provided above the engagement recess 95 and contacts the upper protrusion 83 of the substrate case 71. 1 and an elastic locking piece 107 that locks the stopper projection 84 of the substrate case 71, thereby disengaging the displacement (rearward displacement) of the substrate case 71 in the disengagement direction 95. Further, the first locking member 98 can restrict the displacement in the direction in which the lower protrusion 82 comes out from the engaging recess 95 (the disengagement direction). Further, the second side wall portion 104 facing the front surface plate 75 of the substrate case 71 and the first side wall portion 101 facing the back surface plate 76 are formed, and both sides of the front surface plate 75 and the back surface plate 76 of the substrate case 71 are formed. The support stability of the overall control device 70 can be improved by configuring the support. Further, it is possible to prevent a problem that the substrate case 71 is greatly swung left and right in the installed state and is damaged.

  The front and rear width W2 of the upper protrusion 83 in the substrate case 71 is formed to be larger than the front and rear width W1 of the lower protrusion 82, and the upper protrusion 83 cannot be inserted into the engagement port 95a of the engagement recess 95. Thus, it is possible to prevent the substrate case 71 from being attached upside down with respect to the holding mechanism 90. Further, by observing the upper protrusion 83 and the lower protrusion 82, it is possible to easily determine the mounting posture of the substrate case 71.

  Further, in the holding mechanism portion 90 of the embodiment, the engagement opening 95a of the engagement recess 95 is formed to open upward at the lower edge of the installation region 90a, and the lower protrusion of the substrate case 71 against the engagement recess 95. The part 82 is inserted from above and engaged. Thereby, the engagement state of the lower protrusion 82 and the engagement recess 95 can be maintained by the own weight of the overall control device 70, and the workability of attaching the overall control device 70 to the holding mechanism 90 is improved. It also leads to improving the stability of the substrate case 71 attached to the holding mechanism 90. Further, since the left and right opening widths W5 of the engagement ports 95a in the engagement recess 95 are formed larger than the left and right lateral widths W3 of the lower surface (insertion tip surface) of the lower protrusion 82, the engagement ports of the engagement recess 95 are formed. The lower protrusion 82 can be received in a wide area with respect to 95a, and the lower protrusion 82 can be easily engaged with the engagement recess 95. And while forming a pair of 2nd upper side control part 99 so that the upper side protrusion 83 of the said substrate case 71 may be pinched | interposed from right and left, the separation width W6 between the said 2nd upper side control part 99 is set to the opening width of the right and left of the engagement port 95a. By setting it to be smaller than W5, it is possible to increase the stability of the upper portion of the substrate case 71 while facilitating the insertion of the lower protrusion 82 into the engagement port 95a of the engagement recess 95, and the substrate in the installed state. It is possible to prevent the upper end portion of the case 71 from largely swinging left and right, and to prevent the substrate case 71 from being damaged.

  Each of the first upper restricting portion 98, the second upper restricting portion 99, the first side restricting portion 102, and the second side restricting portion 105 is provided with a guide surface that is inclined so as to move away from the installation region 90a toward the rear. It was. Thereby, when attaching the substrate case 71 to the installation area 90a, the substrate case 71 can be received from a wide range. In addition, by forming an inclined guide surface that is continuous with the operation piece 110 and the action wall 111 of the elastic locking piece 107, the substrate case 71 can be moved from a wide range to the installation region 90a using the operation piece 110. It is possible to guide, and workability when attaching the overall control device 70 is enhanced.

  The first side wall portion 101 is located with the installation area 90a in between, with the rear side protruding height of the first side wall portion 101 relative to the rear surface of the game board 20 as a reference and the protruding height of the second side wall portion 104 being different. Since the front and rear positions of the rear end portion and the rear end portion of the second side wall portion 104 are made different, the receiving area of the substrate case 71 inserted between the first side wall portion 101 and the second side wall portion 104 becomes wider. The mounting workability of the board case 71 is improved. Further, by changing the front and rear positions of the rear end portion of the first side wall portion 101 and the rear end portion of the second side wall portion 104, the substrate case 71 having an inclined posture is changed to one side wall portion (specifically, the first side wall portion 101). It is possible to align the first side regulating portion 102) formed on the side wall portion 101 in contact with the first side regulating portion 102).

  Further, the facing surface 101a of the first side wall 101 facing the back plate 76 of the substrate case 71 is inclined so as to be separated from the back plate 76 of the substrate case 71 toward the rear end side of the first side wall 101. Therefore, the visibility of the back plate 76 of the substrate case 71 in the state of being held by the holding mechanism 90 is enhanced. For this reason, the substrate case 71 can be visually inspected while the displacement of the substrate case 71 is restricted by the first side restricting portion 102 formed on the first side wall portion 101. Further, since the gap S1 between the substrate case 71 and the opposing surface 101a of the first side wall 101 communicates with the gap S2 defined between the substrate case 71 and the ball path unit 132, the pachinko machine The back plate 76 of the substrate case 71 can also be visually inspected from the rear side of 10.

  The upper and lower first side wall portions 101 are configured in a mountain shape that is tapered from the front end side (projection base end side) to the rear end side (projection tip end side). The rigidity of the first side wall portion 101 can be increased while securing a space on the end side. In particular, when the substrate case 71 is installed in a vertical orientation, in order to improve the stability of the substrate case 71, wall portions (engagement recess 95, upper wall portion 97, first side wall portion 101) surrounding the four sides of the substrate case 71 are provided. When the thickness of the second side wall portion 104) is increased, a large space is occupied as a whole, and the installation space for various components on the back side of the game board 20 is pressed. On the other hand, as in the embodiment, the first side wall portion 101 is configured to be larger in the protruding direction than the other wall portions, and the rigidity of the first side wall portion 101 is increased, so that the first side wall portion 101 is By using the guide for guiding the substrate case 71 to the installation region 90a, the force acting when the substrate case 71 is attached can be concentrated on the first side wall portion 101. As a result, the base of the first side wall portion 101 is obtained. It is sufficient to construct the holding mechanism 90 in a space-saving manner.
