  As shown in FIGS. 4, 5, and 15 to 18, the frame-side joint portion 75 includes frame-side connectors 74 a to 74 d that are attached to a mounting plate 97 corresponding to the panel-side connectors 72 a to 72 d. When the game board 6 is mounted on the game board mounting frame 30, it is arranged so as to be substantially parallel to the relay boards 83a to 83c corresponding to the board side joint portion 73 and the front and rear. That is, the rear case 31 on the rear side of the game board mounting frame 30 is provided with a mounting base 98 for the frame side joint portion 75, and screws 100 and the like are attached to a plurality of mounting bosses 99 formed on the front surface of the mounting base 98. A mounting plate 97 is detachably fixed via the.

  As shown in FIGS. 4, 5, and 15 to 18, the mounting base 98 is integrally formed across two sides of the lower peripheral wall portion 51 and the right peripheral wall portion 53 of the rear case 31 and is on the frame side. It has a rectangular rear wall portion 98a that covers the joint portion 75 from the back side, and this rear wall portion 98a is bent to the lower peripheral wall portion 51, the right peripheral wall portion 53, and the other two sides to the front side. And is surrounded by A plurality of mounting bosses 99 are provided on the peripheral side of the front wall side of the rear wall 98a.

  As shown in FIGS. 16 and 18, the mounting plate 97 is formed with four inclined concave portions 101 whose bottom portions are inclined substantially parallel to the relay boards 83 a to 83 c, and the bottom portions of the inclined concave portions 101. Frame side connectors 74a to 74d corresponding to the respective panel side connectors 72a to 72d are attached to the front surface of the panel so that a part thereof is fitted in the opening 101a.

  As shown in FIGS. 15 to 18, the frame-side connectors 74 a to 74 d include a fitting protrusion 102 a that can be fitted in the fitting recess 85 a of the panel-side connectors 72 a to 72 d, and the fitting protrusion 102 a. Between a plurality of provided pin hole groups 102b, a pair of left and right mounting projections 102c, and between the pin hole group 102b and the mounting projections 102c and between the guide portions 85c of the panel side connectors 72a to 72d. It has a pair of left and right guide portions 102d for guiding the fitting projection 102a to the fitting recess 85a.

  As shown in FIG. 18, a floating hole 102e is formed in each mounting protrusion 102c, and a mounting tool 102f such as a screw fixed to a mounting plate 97 is loosely fitted in the floating hole 102e. Accordingly, each frame-side joint portion 75 is freely movable in an arbitrary direction within an allowable range between the floating hole 102e and the attachment tool 102f.

  Harnesses 78a to 78d are connected to the frame-side connectors 74a to 74d on the back side of the mounting plate 97, and the harnesses 78a to 78d are connected to the outside via an extraction port 51a formed in the lower peripheral wall portion 51 of the mounting base 98, for example. After being pulled out, they are connected to the power supply board 67, the payout control board 69, the decoration control board 79, etc., respectively.

  The bent wall 98b of the mounting base 98 is close to the stepped portion 90a of the cover portion 90, and the rear side from the stepped portion 90a of the cover portion 90 protrudes so as not to interfere with the bent wall 98b when the game board 6 is attached or detached. It is inclined to the 81 side.

  In the pachinko machine configured as described above, when the game board 6 is mounted on the game board mounting frame 30, the left edge of the game board 6 is used as a reference for the game board mounting frame 30 as shown by a two-dot chain line A in FIG. After being inserted between the rear wall portion 43b and the front engaging portion 43c at the position O, the opposite side of the game board 6 is pushed into the game board mounting frame 30 as shown by a one-dot chain line B in FIG. The game board 6 is fixed within the game board mounting frame 30 by 45a and 45b.

  When the side opposite to the reference position O of the game board 6 is pushed into the game board mounting frame 30, the board side connectors 72a to 72d of the board side joint part 73 are connected as shown by a solid line C in FIG. After corresponding 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 connector 74a are caused by the relative guiding action of both guide portions 85c and 102d. The fitting projections 102a of ˜74d are fitted, and the two connectors 72a to 72d and 74a to 74d can collectively connect the electrical systems of the front frame 3 side and the game board 6 side.

  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 protrude slightly from the relay boards 83a to 83c, the relay boards 83a to 83c are arranged substantially in parallel on a straight line passing through the fulcrum position P or close to a straight line passing through the fulcrum position P, The board-side connectors 72a to 72d are mounted substantially parallel to the relay boards 83a to 83c so that the board-side connectors 72a to 72d and the frame-side connectors 74a to 74d are attached and detached in a substantially tangential direction. There is an advantage that can be easily done.

  The attachment plate 97 of the frame side joint portion 75 is formed with an inclined concave portion 101 whose bottom portion is inclined substantially parallel to the relay boards 83a to 83c when connected, and an opening is formed on the front surface of the inclined concave portion 101. Since the frame-side connectors 74a to 74d are attached so that a part of the frame-side connectors 74a to 74d is fitted to the 101a, 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 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.

  20 and 21 exemplify a second embodiment of the present invention, and a step portion 82a substantially parallel to the back surface of the game board 6 is formed at one side lower portion of the protruding portion 81 of the ball collecting case 35b. An inclined portion 82 having a substrate attachment portion 86 is constituted by a side wall 82b and a plurality of partition walls 82c on the back side of the portion 82a.

  The side wall 82b is disposed on the opposite side to the side wall 81a with respect to the board side joint portion 73, and a plurality of partition walls 82c extending from the side wall 82b toward the side wall 81a are provided between the upper and lower ends and the middle. The rear end of the partition wall 82c has an inclined shape that gradually decreases from the side wall 82b to the side wall 81a. A receiving portion 87 for receiving the relay boards 83a to 83d is provided on the inner periphery of the side wall 82b and the partition wall 82c, and the side wall 82b, the partition wall 82c, the receiving portion 87, and the like constitute a substrate mounting portion 86, and the first mounting portion 86 is formed. Similarly to the embodiment, the relay boards 83a to 83d are attached to the board attachment portions 86 thereof. Other configurations are the same as those of the first embodiment.

  In this way, a step portion 82a substantially parallel to the game board 6 is formed on the front side of the board-side joint portion 73, and an inclined portion 82 having a substrate attachment portion 86 is provided on the back side of the step portion 82a. Each of the relay boards 83a to 83d may be attached.

  FIG. 22 illustrates a third embodiment of the present invention. In this embodiment, the cover 90 of the connector cover 84 is formed in an arc shape with the rear side approaching the side wall 81a of the protrusion 81, and the front end is in contact with the relay boards 83a to 83d substantially perpendicularly. The attachment portion 92 has a flat plate shape and is fixed to the fixing portion 93 with screws 94 in a substantially vertical direction with respect to the game board 6. Other configurations are the same as those of the first embodiment.

  As described above, the connector cover 84 may be formed in an arc shape. In that case, it is desirable that the rear end of the connector cover 84 be located within the radius connecting the fulcrum position P and the front end with the fulcrum position P as the center. The mounting portion 92 may have a flat plate shape or other shape and structure as long as the mounting portion 92 is fixed to the fixing portion 93 with screws 94 in a substantially vertical direction with respect to the game board 6.

  FIG. 23 illustrates a fourth embodiment of the present invention. In this embodiment, when each board side connector 72a-72d of the board side joint part 73 and each frame side connector 74a-74d of the frame side joint part 75 are detachably fitted with a predetermined fitting allowance S1, The half of the fitting allowance S1 is positioned on the inclined surface S passing through the fulcrum position P, and the panel side connectors 72a to 72d, the relay boards 83a to 83d, and the frame side connectors 74a to 74d are provided. The inclined surface S is arranged substantially in parallel. Other configurations are the same as those of the first embodiment.

  In this way, when the game board 6 is attached to or detached from the game board mounting frame 30, the board side connectors 72a to 72d of the board side joint part 73 and the frame side connectors 74a to 74d of the frame side joint part 75 are substantially tangent. Can be fitted and removed in the direction.

  FIG. 24 illustrates a fifth embodiment of the present invention. When the board side connectors 72a to 72d are arranged in the board side joint part 73 with respect to the relay boards 83a to 83d, the straight line is arranged on a straight line passing through the rear left part of the game board 6 as shown in FIG. Alternatively, as shown in FIG. 24 (b), the straight line may be arranged on a straight line passing in front of the left front part of the game board 6.

  When the board-side connectors 72a to 72d and the frame-side connectors 74a to 74d are fitted and removed in the tangential direction, the straight line passing through the fulcrum position P is used as a reference and relayed on the straight line as exemplified in the first embodiment. Although it is desirable to arrange the boards 83a to 83c and the like, it is not always necessary to arrange them on a straight line passing through the fulcrum position P in a strict sense, and they are arranged as shown in FIG. 24 (a) or (b). Also good.

  This is because the required range in the vicinity of the fulcrum position P at the front left end of the game board 6, for example, the thickness of the game board 6 from the fulcrum position P to the front and rear sides, or a distance slightly larger than that. Even if the relay boards 83a to 83c are arranged on a straight line passing through the vicinity area Z, the left and right widths of the game board 6 are very large compared to the front and rear dimensions of the board side connectors 72a to 72d. Since the distance to the board side connectors 72a to 72d is large, the board side connectors 72a to 72d and the frame side connector 74a are arranged when the game board 6 is rotated by arranging as shown in FIG. 24 (a) or (b). -74d can be fitted and removed in a substantially tangential direction. Therefore, it is sufficient if the relay boards 83a to 83c are arranged on a straight line passing through the neighboring areas Z on both the front and rear sides of the fulcrum position P on the left end side of the game board 6. The same applies to the case where the rear ends of the board-side connectors 72a to 72d are arranged on the straight line.

  As mentioned above, although embodiment of this invention was explained in full detail, this invention is not limited to these embodiment, A various change is possible in the range which does not deviate from the meaning of this invention.
