  In the pachinko machine configured as described above, when the game board 6 is mounted on the game board mounting frame 30, the engaging members 106 of the upper and lower pushing / pushing means 45 and 46 are directed forward and inward as shown by the solid lines in FIG. In this state, the left edge portion of the game board 6 is placed between the rear wall portion 43b and the front engagement portion 43c in accordance with the reference position O of the game board mounting frame 30, and then the right end side of the game board 6 is played. When pushed into the board mounting frame 30, the notches 6 b and 6 c on the right edge of the game board 6 are engaged with the engaging members 106 of the pushing and pushing means 45 and 46.

  For example, in the push-in / push-out means 45, as shown in FIG. 24, after the game board 6 is engaged with the engaging member 106, when the operation portion 107 of the engaging member 106 is pressed rearward, the engaging member 106 is It rotates clockwise around the first pivot 105 (direction indicated by arrow a) and is pushed backward into the game board mounting frame 30 by the push-in engagement portion 110 of the front engagement body 111. As a result, the game board 6 is fitted to a predetermined position in the game board mounting frame 30 while turning counterclockwise around the fulcrum position P (in the direction of arrow b in FIG. 23).

  Further, when the engaging member 106 rotates clockwise around the first pivot 105, the operation link 118 and the connecting link 120 of the lock mechanism 108 extend along with the rotation, and the engaging position 106 is engaged to the mounting position Q of the game board 6. When the joint member 106 is rotated, it is in a maximum extension state, and no longer rotates. Then, if the operation portion 109 of the operation link 118 is slightly operated counterclockwise, the operation link 118 and the connecting link 120 are refracted in the opposite directions, and the contact portions 122 and 123 come into contact with each other. As shown, the engaging member 106 can be locked so as not to be released in a state where the game board 6 is located at the fitting position Q.

  On the other hand, when the game board 6 enters the peripheral wall parts 41a to 44a of the game board mounting frame 30 by turning counterclockwise around the fulcrum position P, the peripheral wall part 41a of the upper horizontal support frame 41 and the right vertical support frame 44, there are pressing portions 47, 48 constituted by reinforcing ribs 47a, 48a on the inner surface of the peripheral wall portion 44a, and the upper side surface and the right side surface of the game board 6 are the inclined surfaces 47b, 48b for pressing the reinforcing ribs 47a, 48a. And are fitted into the game board mounting frame 30 while being guided along the pressing inclined surfaces 47b and 48b. Therefore, if the game board 6 is pushed into the game board mounting frame 30, the game board 6 can be pressed to the reference position O in the game board mounting frame 30 by the pressing portions 47 and 48, and the game is matched to the reference position O. The board 6 can be fixed and locked.

  Further, pressing portions 47 and 48 are provided inside the support frames 41 and 44, and the game board 6 fitted in the game board mounting frame 30 is pressed to the reference position O while being guided by the pressing parts 47 and 48. Therefore, it is not necessary to make the pressing portions 47 and 48 themselves movable, and the structure is simple and can be implemented easily and inexpensively.

  Moreover, since the reaction force when the game board 6 is pressed by the pressing portions 47 and 48 can be directly received by the respective support frames 41 and 44 of the game board mounting frame 30, it is not necessary to be movable. Thus, the durability of the pressing portions 47 and 48 is improved.

  Further, since the pressing portions 47 and 48 also serve as the reinforcing ribs 47a and 48a, the pressing portions 47 and 48 are provided on the peripheral wall portions 41a and 44a of the supporting frames 41 and 44, and at the same time, the pressing portions 47 and 48 support the supporting frame. It is also possible to reinforce the peripheral wall portions 41a and 44a of 41 and 44.

  A reaction force is applied to the peripheral wall portion 44a of the right vertical support frame 44 at the portion corresponding to the reinforcing rib 48a when the game board 6 is laterally pressed to the reference position O. Has a vertical reinforcing portion 125 of the reinforcing member 49 in the vertical direction along the peripheral wall portion 53 of the rear case 31, and the vertical vertical supporting portion 44 reinforces the right vertical supporting frame 44. Although the gap between the game board 6 and the outer frame 2 is small and it is difficult to secure a sufficient thickness in the left-right direction of the peripheral wall portion 44a, deformation, damage, etc. on the right vertical support frame 44 side can be prevented in advance. It is possible to reliably press the game board 6 to the reference position O by the pressing portions 47 and 48.

  Moreover, the vertical reinforcing portion 125 of the reinforcing member 49 is provided along the peripheral wall portion 53 of the rear case 31 inside the back side of the right vertical support frame 44, and the front end mounting portion 125a is fixed to the back surface of the right vertical support frame 44 and the like. Therefore, the right vertical support frame 44 is reinforced by the vertical reinforcing portion 125 of the reinforcing member 49. However, by providing the reinforcing member 49, the right and left width on the right vertical support frame 44 side is increased. Nor.

  Further, when the game board 6 is rotated around the fulcrum position P and pushed into the game board mounting frame 30, at the final stage, as shown by the solid line in FIG. After 72d corresponds to the front side of the frame side connectors 74a to 74d of the frame side joint portion 75, the fitting concave portions 85a of the panel side connectors 72a to 72d and the frame side are caused by the relative guiding action of both the guide portions 85c and 102d. The fitting protrusions 102a of the connectors 74a to 74d are fitted. When the game board 6 is pushed down to the mounting position Q as shown by a two-dot chain line in FIG. 25, both connectors 72a to 72d and 74a to 74d collectively connect the electrical system between the front frame 3 side and the game board 6 side. Can be connected.

  When the panel-side connectors 72a to 72d and the frame-side connectors 74a to 74d are fitted, the frame-side joint portion 75 is pressed backward by the fitting resistance between the two, but the back side of the frame-side joint portion 75 is reinforced. There is a back reinforcing portion 128 of the member 49, and the frame side joint portion 75 is reinforced by the reinforcing member 49 via the back reinforcing portion 128. Therefore, the frame side joint portion 75 does not move backward, and the board side The connectors 72a to 72d and the frame side connectors 74a to 74d can be reliably fitted.

  Accordingly, it is possible to prevent contact failure between the panel side connectors 72a to 72d and the frame side connectors 74a to 74d, and to prevent damage on the frame side joint portion 75 and the mounting base 98 side supporting the same. Can do.

  The reinforcing member 49 extends greatly from the bent portion 127 at one end of the back reinforcing portion 128 to the vertical reinforcing portion 125 through the protruding portion 126 to the front side, and the mounting portion 125a at the front end of the vertical reinforcing portion 125 is connected to the game board mounting frame. Since it is fixed to the back surface of 30 or the like, it is possible to reduce the burden on each attachment portion as compared with the case where the attachment portion 125a is in the very vicinity of the back reinforcing portion 128.

  The game board 6 rotates counterclockwise about a fulcrum position P that engages with the front engagement portion 43c, and the board side connectors 72a to 72d and the frame side connectors 74a to 74d are fitted to each other by the rotation. At that time, the board-side connectors 72a to 72d and the frame-side connectors 74a to 74d are fitted in a substantially tangential direction of a circle with the fulcrum position P as the center.

  Therefore, even if there is a slight misalignment between the board-side connectors 72a to 72d and the frame-side connectors 74a to 74d, the board-side connectors 72a to 72d and the frame-side connectors 74a to 74d are guided by the guiding action of the guide portions 85c and 102d. 74d can be fitted without difficulty. Further, the connectors 72a to 72d and 74a to 74d can be connected with a small amount of floating of the frame side connectors 74a to 74d.

  Further, since the amount of play of the frame side connectors 74a to 74d can be suppressed to reduce the positional deviation between the plurality of frame side connectors 74a to 74d of the frame side joint portion 75, the game board 6 is pushed into the game board mounting frame 30. In some cases, the plurality of panel-side connectors 72a to 72d and the frame-side connectors 74a to 74d can be opposed to each other within a range that can be guided to each other by the guide portions 85c and 102d. Since some positions of the side connectors 74a to 74d do not match, the connection cannot be made, and the connection operation is not repeated a plurality of times while the game board 6 is taken in and out of the game board mounting frame 30.

  When the board-side connectors 72a to 72d and the frame-side connectors 74a to 74d are attached / detached, it is desirable that they are attached / detached in the tangential direction. However, the relay boards 83a to 83c are compared with the lateral width of the game board 6. Since the board-side connectors 72a to 72d are slightly projected from the board, the relay boards 83a to 83c are arranged on a straight line passing through the fulcrum position P, and are substantially parallel to the relay boards 83a to 83c. Since the board-side connectors 72a to 72d and the frame-side connectors 74a to 74d are attached and detached in a substantially tangential direction by attaching the 72a to 72d, there is an advantage that the design and the like can be facilitated.

  In the attachment plate 97 of the frame side joint portion 75, an inclined concave portion 101 whose bottom portion is inclined substantially parallel to the relay boards 83a to 83c when connected is formed in a recessed shape, and an opening 101a is formed in the front surface in the inclined concave portion 101. Since the frame-side connectors 74a to 74d are attached so as to be partially fitted to each other, the size of the frame-side joint portion 75 in the front-rear direction can be reduced.

  Further, an inclined portion 82 is provided in the ball collecting case 35b on the back side of the game board 6, and the back side of the inclined portion 82 is used as a board side joint portion 73. The board side joint portion 73 is provided with board side connectors 72a to 72d. Since the boards 83a to 83c are arranged, the board side joint part 73 can be provided with a simple structure by using a part of the ball collecting case 35b.

  Further, there is an inclined portion 82 in the vicinity of the protruding portion 81 of the ball collecting case 35b, and the relay boards 83a to 83c of the panel side joint portion 73 are arranged on the inclined portion 82, but the connector cover 84 is also used for holding. Since the connector cover 84 presses and fixes the end portions of the relay boards 83a to 83c on the protruding portion 81 side, the relay boards 83a to 83c have a simple structure despite being extremely cramped in terms of space. There exists an advantage which can fix 83c reliably.

  At that time, there is a predetermined gap between the connector cover 84 and the protruding portion 81, and there is a mounting portion 92 corresponding to the front side of the gap on the protruding portion 81 side of the connector cover 84, and an inclination near the protruding portion 81. Since there is a fixing portion 93 for fixing the attachment portion 92 from the back side to the portion 82 with the screw 94, the connector cover 84 can be easily inserted by inserting a screwdriver or the like from the gap between the protruding portion 81 of the connector cover 84 and the rear end side. Can be fixed.

  The mounting portion 92 has a bottomed cylindrical shape whose center passes through the gap on the rear end side of the connector cover 84 and the protruding portion 81, and the fixing portion 93 is detachably fitted from the back side in the front-rear direction. By adopting the protrusion shape, the posture of the connector cover 84 can be stabilized before the screw 94 is tightened. Further, by bringing the front end of the fitting cylinder portion 92a into contact with the relay substrates 83a to 83c, the relay substrates 83a to 83c can be fixed at the end portion on the protruding portion 81 side.

  When detaching the game board 6 from the game board mounting frame 30, the right side of the game board 6 is pushed forward by operating the push-in / push-out means 45, 46. For example, in the push-in / push-out means 45, the operation portion 109 of the operation link 118 is operated to the front side, and the operation link 118 is rotated clockwise around the first connecting shaft 114 to be locked at the mounting position Q by the lock mechanism 108. To release.

  Next, when the operating portion 107 of the engaging member 106 is operated to the front side, the engaging member 106 rotates counterclockwise from the lateral position to the front inward position around the first pivot 105, so that the right side of the game board 6 Is pushed from the back to the front side by the pushing engagement portion 112 of the rear engagement body 113. Then, if the right end side of the game board 6 comes out of the game board mounting frame 30, the game board 6 may be removed from the game board mounting frame 30 by placing a hand on an appropriate position of the game board 6.

  When the game board 6 is pushed out, resistance for removing the board side connectors 72a to 72d from the frame side connectors 74a to 74d is applied to the frame side joint part 75, and the frame side joint part 75 is pulled to the front side. However, since the frame side joint portion 75 is reinforced by the reinforcing member 49, the frame side joint portion 75 does not move forward.

  FIG. 26 illustrates a second embodiment of the present invention. In this embodiment, the reinforcing member 49 includes a vertical mounting base 129 that is disposed vertically along the outer side of the peripheral wall portion 53 of the rear case 31 and has mounting portions 129a on both upper and lower ends. A back reinforcing portion 128 corresponding to the back side of the frame side joint portion 75 is provided via a protruding portion 126 that protrudes rearward from the substantially vertical center and a bent portion 127 that is bent from the rear end to the back side. Other configurations are the same as those of the first embodiment.

  When the frame side joint portion 75 is reinforced by the reinforcing member 49, a relatively short mounting base 129 is provided in the vertical direction along the outer side of the peripheral wall portion 53 of the rear case 31, and the mounting base 129 is interposed therebetween. You may fix to the back side of the front frame 3. FIG.

  FIG. 27 illustrates a third embodiment of the present invention. In this embodiment, the reinforcing member 49 is also used for mounting the frame side joint portion 75, and the frame side joint portion 75 is attached to the front surface of the back reinforcing portion 128. Therefore, there is no mounting base 98 integral with the rear case 31 as exemplified in the first embodiment. Other configurations are the same as those of the first embodiment.

  It is also possible to attach the frame side joint portion 75 to the reinforcing portion itself of the reinforcing member 49 as in this embodiment. In addition, when attaching the frame side joint part 75 to the reinforcement member 49 in this way, it is desirable that the frame side joint part 75 has a case shape that covers the back sides of the frame side connectors 74a to 74d.
