The screw 41 is fixed and attached. As shown in FIG. 4, the handle pedestal portion 40 has a cylindrical shape as a whole from a front round thin tube portion 40a and a rear square thick tube portion 40b, and a square thick tube as shown in FIG. A closing plate 42 is stretched at the rear end portion of the portion 40 b, and a through hole 43 through which the small diameter portion 30 c of the rear gripping portion 30 is inserted is provided at the center of the closing plate 42. In addition, a through hole 44 through which the lock plate 37 is inserted is formed in the closing plate 42 on one side thereof. Further, on the inner peripheral surface of the round thin cylindrical portion 40a, a tapered concave surface portion having substantially the same inclination as the tapered convex surface portion 36 of the hitting force adjusting handle 13 in the front half and gradually decreasing in inner diameter as it advances backward. 45 is formed, and the tapered convex surface portion 36 and the tapered concave surface portion 45 come into sliding contact with each other.

  The handle pedestal portion 40 is covered with a cover member 46 disposed and fixed on the front surface of the support plate 27. A through hole 47 is formed in the front surface of the cover member 46, and the round thin tubular portion 40 a protrudes forward through the through hole 47.

  As shown in FIGS. 5 and 6, the support plate 27 has a mounting hole through which the small diameter portion 30 c of the hitting force adjusting handle 13 and the lock plate 37 are inserted at the intersection of the upper plate portion 27 a and the side plate portion 27 b. 48 is established. In addition, a relatively large operation port 49 having a substantially rectangular shape is provided in the support plate 27 located above the mounting hole 48. A pair of holding plates 50 a and 50 b are provided on the upper edge of the mounting hole 48 and the lower edge of the operation port 49 so as to protrude rearward substantially at a right angle to the support plate 27. These holding plates 50a and 50b are substantially parallel to the lock plate 37 when the small diameter portion 30c of the hitting force adjusting handle 13 and the lock plate 37 are inserted into the mounting hole 48, and are locked to both the holding plates 50a and 50b. Circular second support holes 51 a and 51 b are formed on the same axis as the first support hole 38 of the plate 37.

  The lock rod 52 is removably inserted from above into the second support holes 51a and 51b. The lock bar 52 is made of a metal round bar, has an outer diameter substantially the same as the inner diameter of the second support holes 51a, 51b, and is provided with a bent flange 52a bent at a right angle at the upper end. The outer diameter of the lock rod 52 is substantially the same as the tapered concave portion 39 formed on the inner peripheral surface of the first support hole 39 on the outer peripheral surface of the first support hole 39. A tapered convex surface portion 53 that is in sliding contact with the portion 39 is formed.

  Further, a compression spring 54 as an elastic means is inserted into the lock rod 52 at the tip end side, and the compression spring 54 rides on the upper surface of an E-ring 55 attached to the tip end portion of the lock rod 53. When the ball striking force adjusting handle 13 is inserted into the handle base 40 from the front side and the lock rod 52 is inserted into the second support holes 51a and 51b from above, the compression spring 54 is connected to the holding plates 50a and 50b. In the meantime, it is interposed between the upper holding plate 50a and the E-ring 55 so as to always urge the lock rod 52 downward. As a result, the tip of the lock rod 52 passes through the lower second support hole 51b and enters the first support hole 38, and the tapered convex surface portion 53 on the lock rod 52 side and the tapered concave surface on the first support hole 38 side. The portion 39 is in sliding contact. At this time, the E-ring 55 is positioned slightly above the lower holding plate 50b.

  At the upper edge of the operation port 49, there is provided a regulating plate 56 that is bent at a right angle from the support plate 27 so as to be displaced from the both holding plates 50a and 50b. A stop piece 57 that bends downward is provided at the rear end of the regulating plate 56. With the lock rod 52 inserted through the second support holes 51a and 51b from above, the lock rod 52 is rotated in a plane orthogonal to the central axis thereof, thereby providing a bent flange at the upper end of the lock rod 52. 52a intervenes on the lower surface of the restricting plate 56, and further abuts against the stop piece 57 and stops. In this state, the upper end is supported by the restriction plate 56 and the lock rod 52 cannot be pulled upward. The operation of the lock bar 52 can be easily performed by inserting a finger into the operation port 49 from the front side with the front plate 6 opened.

  The pachinko gaming machine according to the present invention has the above-described configuration, and the lock bar 52 is inserted into the second support holes 51a and 51b of the holding plates 50a and 50b with the compression spring 54 interposed between the holding plates 50a and 50b. Further, it is further rotated so that the bent flange portion 52a at the upper end portion is disposed below the restricting plate 56.

  Next, when attaching the ball striking force adjusting handle 13, the front plate 6 is opened and the round thin cylindrical portion 40a of the handle pedestal portion 40 is projected forward from the through hole 47, and the front surface of the support plate 27 is covered. The member 46 is fixed with a screw 58. Then, a finger is inserted into the operation port 49 from the front side, and the lock rod 52 is rotated in the reverse direction to disengage the bent flange 52a from the restricting plate 56, and is locked against the bias of the compression spring 54. The rod 52 is pulled upward, and its tip is held at a position higher than the lower holding plate 50b.

  In this state, the ball striking force adjusting handle 13 is inserted into the round thin cylindrical portion 40a from the base end side. As a result, the small diameter portion 30c is inserted into the through hole 43 in the handle base 40 and protrudes to the back side of the support plate 27. Similarly, the lock plate 37 is also inserted into the through hole 44 and protrudes to the back side of the support plate 27. . In this case, the first support hole 38 of the lock plate 37 matches the second support hole 51b of the lower holding plate 50b.

  Therefore, when the lock rod 52 is separated from the fingertip, the lock spring 52 is pulled downward by the urging force of the compression spring 54, and the tapered convex surface portion 53 at the tip of the lock rod 52 is brought into sliding contact with the tapered concave surface portion 39 of the first support hole 38. At the same time, the tapered convex portion 36 on the outer peripheral surface of the hitting force adjusting handle 13 is in sliding contact with the tapered concave portion 45 on the inner peripheral surface of the handle pedestal 40, so that the hitting force adjusting handle 13 rattles against the handle pedestal 40. It is firmly fixed without any problems.

  As shown in FIG. 7, the lock rod 52 is rotated once again, and the bent flange portion 52 a at the upper end thereof is disposed on the lower surface of the regulating plate 56. Since the upward movement of the lock bar 52 is restricted, it does not come out even if the hitting force adjusting handle 13 is lifted unnecessarily from the front side. Finally, the front plate 6 is closed. In this way, the hitting force adjusting handle 13 is detachably attached to the handle base 40.

  Since the present invention has the above-described configuration, for example, when the hitting force adjusting handle 13 is replaced, the front plate 6 is opened as shown in FIG. 8 and the lock rod 52 is removed from the first support hole 38 of the lock plate 37. Therefore, the ball hitting force adjusting handle 13 can be easily maintained because it is not necessary to attach and detach the screw and can be operated from the front side. Further, since the lock bar 52 is covered by the front plate 6, the hitting force adjusting handle 13 cannot be removed from the front side of the pachinko gaming machine P, thereby preventing an illegal act performed by removing the hitting force adjusting handle 13. The

  In the present invention, the front plate 6 on which the upper and lower ball trays 5 and 7 are mounted as the open / close members has been described. However, the present invention can be applied to an open / close member in which the transparent plate holding frame 4 is also integrated. Of course.
