A recess 71 is formed. Specifically, the small-diameter recess 71 is an arc centered on the substantially circumference of the large-diameter shaft hole 70. Further, guide means 72 for fitting the large-diameter shaft hole 70 and the large-diameter shaft portion 66b to the lower movable hinge member 55a and the lower fixed hinge member 50b is provided. The guide means 72 includes a shaft portion 72a provided on the lower movable hinge member 55a and a recess 72b formed on the lower fixed hinge member 50b, and the inner surface of the recess 72b contacts the shaft portion 72a when the front frame 2 is closed. Thus, the large-diameter shaft hole 70 of the lower movable hinge member 55a is provided so as to be guided to the large-diameter shaft portion 66b of the lower fixed hinge member 50b.

  The upper and lower hinge mechanisms 3a and 3b are configured as described above. In order to pivotally support the front frame 2 on the outer frame 1, as shown by solid lines in FIG. 11 and FIG. The small-diameter concave portion 71 of the lower movable hinge member 55b of the front frame 2 is matched with the small-diameter shaft portion 66a of the front frame 2 so that the small-diameter shaft portion 66a serves as a mounting shaft, and the upper surface of the large-diameter shaft portion 66b is the lower movable hinge member. As shown in FIG. 11, a small-diameter shaft portion 68a of the shaft pin 68 of the upper movable hinge member 55a is brought into contact with the shaft hole 63 from the guide groove 62 of the upper fixed hinge member 50a. Thus, the outer frame 1 and the front frame 2 are connected at the same time as positioning is performed. At this time, the guide groove 62 makes it easy to guide the shaft pin 68 to the shaft hole 63. Then, when the front frame 2 is rotated in the closing direction as shown by a chain line in FIG. 13A using the small-diameter shaft portion 66a and the small-diameter shaft portion 68a as the support shaft, the arc surface of the concave portion 72b of the guide means 72 becomes the shaft portion. As shown in FIG. 13 (b), the small-diameter concave portion 71 comes off from the small-diameter shaft portion 66a, and as shown in FIGS. 12 and 13 (c), the concave portion 72b and the shaft portion 72a of the guide means 72 are contacted. , The large-diameter shaft hole 70 of the lower movable hinge member 55b is guided so as to match the large-diameter shaft portion 66b of the lower fixed hinge member 50b, and is moved downward and fitted, and the upper movable hinge member 55a. The large-diameter shaft portion 68b is also moved downward to fit into the large-diameter bearing portion 64 of the upper fixed hinge member 50a, and the front frame 2 is mounted on the machine frame 1 with the large-diameter shaft portion 66b and the large-diameter shaft portion 68b as rotation axes. Is pivotally mounted on the shaft. Further, the removal can be easily removed by lifting the front frame 2 with the locking mechanism 47 released.

  As described above, the front frame 2 can be pivotally mounted on the machine frame 1 with one touch with the lower hinge mechanism 3b as a fulcrum without simultaneously connecting and fitting the upper and lower hinge mechanisms 3a and 3b. The large-diameter shaft hole 70 is inserted into the small-diameter shaft portion 66a so that the guide can be easily inserted so that the first fulcrum can be easily determined and the workability is good. The open groove 62 is expanded toward the outside, so that the small-diameter shaft portion 68a can be easily guided to the shaft hole 63 and the upper hinge mechanism 3a can be easily connected. Further, the upper hinge mechanism 3b is not limited to the above embodiment, and may be a single-thickness shaft pin 68 and shaft hole 63 as shown in FIG. 14, and preferably as shown by the chain line in FIG. It is preferable to guide the shaft pin 68 to the shaft hole 63 using the above-described open groove 62, and further, as shown in the figure, the insertion direction of the large diameter shaft hole 70 and the connecting direction of the upper hinge mechanism 3a. By making the (opening direction of the opening groove 62) the same direction, workability is improved. Further, in the present embodiment, the upper fixed hinge member 50a is integrally formed by die casting such as aluminum alloy so as to provide a guide groove. However, the upper fixed hinge member 50a is formed by press molding and at the same time is guided by press working. A groove may be formed, and further, the guide groove is not formed integrally with the upper fixed hinge member 50a, and another member such as a decorative cover member 51 covering the front surface of the upper fixed hinge member 50a as shown in FIG. Alternatively, the guide groove 51a may be formed on the machine frame side.

  Further, as shown in FIG. 16, the support shaft 66 of the lower fixed hinge member 50b may be formed as a truncated cone by connecting a small-diameter shaft portion 66a and a large-diameter shaft portion 66b via a tapered surface. Is supported at the intersection of the small-diameter shaft portion 66a and the tapered surface, and the upper hinge mechanism 3a is linked as a fulcrum. In this state, the inclined surface acts as a guide means by loosening the pressing force of the lower hinge mechanism 3b. Since the large-diameter shaft hole 70 is fitted to the large-diameter shaft portion 66b by moving down along the inclined surface of the truncated cone due to its own weight, it is not necessary to provide a separate guide means 72 and forcibly guide it. Although the small-diameter shaft portion 66a and the large-diameter shaft portion 66b are provided concentrically, they are not provided concentrically, but the movable hinge member at the time of supporting the other hinge mechanism by shifting the axis. The mounting area of the taper surface may be increased to increase stability, or the inclination angle α of the tapered surface may be changed while the length of the small-diameter shaft portion 66a remains unchanged. The small-diameter shaft portion 66a may be an ellipse instead of a perfect circle, and may be a fulcrum that is thinner than the diameter of the large-diameter shaft hole 70 and can be easily fitted into the large-diameter shaft hole 70 to connect the other hinge mechanism. Further, it is preferable that the small-diameter shaft portion 66a is a D-cut and a prism having at least one plane, and the support portion of the large-diameter shaft hole 70 is supported in two points by the flat portion of the small-diameter shaft portion 66a in a stable state. Other hinge mechanisms can be linked. Needless to say, the prism is a column having a polygonal bottom surface, and it goes without saying that it may be a triangular prism, a quadrangular prism, or a polygonal prism.

  Further, the lower movable hinge member 55b is a daruma type in which a small-diameter recess 71 is provided at the periphery of the large-diameter shaft hole 70. However, as shown in FIG. 17, the large-diameter shaft hole 70 and the small-diameter recess 71 are connected in a tangential manner. It may be oval. Further, only the large-diameter shaft hole 70 may be provided without providing a positioning portion, and the peripheral edge of the large-diameter shaft hole 70 can be appropriately brought into contact with the small-diameter shaft portion 66a as a fulcrum. At this time, as shown in FIG. 18, at least the small-diameter shaft portion 66a is preferably a truncated cone having an inclination angle α of about 45 ° to 60 °, and the upper hinge mechanism 3a is connected to the large-diameter shaft portion 66b by a tapered surface. Can be guided to. Further, it is preferable that the inner peripheral lower surface of the large-diameter shaft hole 70 is a tapered surface along the inclined surface of the support shaft 66.

  Further, when the support shaft 66 is a truncated cone, it is preferable to provide a mounting portion 77 with the small-diameter shaft portion 66a as a fulcrum on the inclined surface as shown in FIGS. 19 and 20, to stabilize the support state. The shaft hole of the lower movable hinge member 55 b is formed with a fan-shaped recess 78 that matches the mounting portion 77 at the periphery of the large-diameter shaft hole 70. The hinge mechanism configured as described above is in a stable state in which the periphery of the large-diameter shaft hole 70 of the lower movable hinge member 55b is in contact with the small-diameter shaft portion 66a and supported by the mounting portion 77 as shown in FIG. Thus, the upper hinge mechanism 3a can be linked. Then, when the front frame 2 is rotated in this state, as shown in the chain line of FIG. 20, the concave portion 78 is aligned with the placement portion 77, and is removed from the support of the placement portion 77, so 70 is guided to the large-diameter shaft portion 66b, and the front frame 2 is rotatably mounted. The concave portion 78 is preferably formed larger than the placement portion 77 within the semicircle of the large diameter shaft hole 70.

  Further, as shown in FIGS. 21 to 23, D-cut may be performed with the small-diameter shaft portion 66a as a truncated cone, and the maximum diameter portion of the small-diameter shaft portion 66a may be equal to the diameter of the large-diameter shaft portion 66b. When the small-diameter shaft portion 66a is used as a support shaft for linking the other hinge mechanism, the shaft pins of the upper and lower hinge mechanisms are provided in a straight line and perpendicularly, and therefore, as shown in FIG. Try to connect the front frame 2 by tilting it. Therefore, even if the maximum diameter portion of the small diameter shaft portion 66a is equal to the diameter of the large diameter shaft portion 66b, the edge portion of the large diameter shaft hole 70 is always supported by the mounting portion 77 as shown in FIGS. Is done. When the shaft hole and the shaft pin of the other hinge mechanism are linear and the front frame 2 is vertical, the large-diameter shaft hole 70 automatically fits into the large-diameter shaft portion 66b. The opening / closing body can be freely opened and closed without giving the 77 an inclination as a guide means.

  In the above-described embodiments, the large-diameter shaft portion 66b and the large-diameter shaft hole 70 have been perfect circles, but either one may be a square shape. For example, as shown in FIGS. 24 and 25, when the large-diameter shaft hole 70 is rectangular, the large-diameter shaft portion 66b may be an inscribed circle of the large-diameter shaft hole, and as shown by a chain line in FIG. A square-shaped large-diameter shaft hole 70 is brought into contact with the D-cut small-diameter shaft portion 66a in the drawing to serve as a fulcrum portion for connecting the upper hinge mechanism 3a. At this time, since the large-diameter shaft hole 70 is a square hole and the small-diameter shaft portion 66a has a D-cut surface, the contact portion as a support shaft becomes a surface contact and connects the upper hinge mechanism 3a in a more stable state. can do. Then, after connecting the upper hinge mechanism 3a, the inclination of the mounting portion 77 serves as a guide means, and the rectangular large-diameter shaft hole 70 is fitted into the large-diameter shaft portion 66b so that the opening / closing body can be freely opened and closed. In addition, it is preferable to change the inclination of the mounting portion 77 according to the intersection line position between the small diameter shaft part 66a and the large diameter shaft part 66b, and the intersection line position is located behind the center part of the large diameter shaft part 66b. If the placement part is wide, the inclination angle is about 45 ° to 60 °, or if the intersection is located in front of the center of the large-diameter shaft part 66b and the placement part is narrow, the inclination angle It is better to make the slope of about 15 ° to 30 °.

  Further, if the large diameter shaft hole 70 is a square hole, there is always a large diameter portion longer than the diameter of the large diameter shaft portion 66b, so that it is easier to fit into the small diameter shaft portion 66a. In addition, when fitting the large diameter shaft hole 70 into the small diameter shaft portion 66a, the depth side is smaller in the depth side than the width of the D cut surface in the drawing, so that the size of the D cut surface is naturally. The direction fitted from the side becomes easier to aim at the small-diameter shaft portion 66a. Furthermore, as shown in FIG. 26, the corner portions of the large-diameter shaft hole 70 and the corner portions of the small-diameter shaft portion 66a are used as fulcrums, so that they are supported by contact with two surfaces, thereby enabling more stable positioning. In contrast, the large-diameter shaft portion 66b may be a prism instead of a perfect circle. At this time, the large-diameter shaft hole 70 may be a circumscribed circle of the large-diameter shaft portion 66b.

  The small diameter shaft portion 66a in the present invention is a shaft portion having a smaller diameter portion than the maximum diameter portion of the large diameter shaft portion 66b. For example, as shown in FIG. 27, the large diameter shaft portion 66b is the small diameter shaft portion 66a. In the present invention, there is no influence even if the same small diameter portion is provided. Needless to say, it is most stable to support at the maximum diameter portion of the large-diameter shaft portion 66b in the above-described two-point support and one-surface and two-surface support.

  28 to 30 show an embodiment in which the front frame 2 as an opening / closing body is not unnecessarily removed after being connected by a vertical hinge mechanism. In this embodiment, as shown in FIG. 28, a rib-like mounting portion 77 is provided in the middle of the small-diameter shaft portion 66a of the support shaft 66, and the lower end has a large diameter. A guide portion 79 is provided as a guide means for guiding the large-diameter shaft hole 70 so as to be fitted into the large-diameter shaft portion 66b. On the other hand, the large-diameter shaft hole 70 of the movable hinge member 55b is formed with a concave portion 78 that matches the placement portion 77 as in the above embodiment, and the outer diameter of the concave portion 78 is at least the upper surface of the placement portion 77. The larger diameter is larger than the larger one of the outer diameter and the diameter protruding from the outer periphery of the large-diameter shaft portion 66b. As a matter of course, the length of the large-diameter shaft portion 66b from the large-diameter shaft portion 66b to the lower surface of the mounting portion 77 is selected to be longer than the thickness of the large-diameter shaft hole 70 portion of the movable hinge member 55b.

  Next, this operation will be described. First, as shown in FIG. 29, the periphery of the large-diameter shaft hole 70 of the lower movable hinge member 55b is brought into contact with the small-diameter shaft portion 66a and supported by the mounting portion 77, and the upper hinge mechanism 3a is connected in a stable state. When the front frame 2 is rotated, the concave portion 78 coincides with the placing portion 77 as shown by a chain line in FIG. 29, and the lower movable hinge member 55b is moved downward as shown in FIG. Further, as shown in FIG. 30, the large diameter shaft hole 70 is fitted into the large diameter shaft portion 66b, and the front frame 2 is rotatably mounted. As shown in FIG. 28, the front frame 2 that is rotatably mounted in this manner has a thick outer periphery of the large-diameter shaft hole 70 as shown by the chain line in the figure except where the concave portion 78 and the mounting portion 77 match. Since the lower hinge mechanism 3b is not released from contact with the lower end of the projecting mounting portion 77 from the outer periphery of the radial shaft portion 66b, the front frame 2 is not unnecessarily removed when the front frame 2 is opened or closed.

  FIGS. 31 and 32 show an embodiment in which a positioning means is provided in which the shaft pin 75 and the shaft hole 74 are linear, and the upper hinge mechanism 3a includes a fixed hinge member 50a in which the shaft hole 74 is provided in the bearing plate 61; It is comprised with the movable hinge member 55a which provided the shaft pin 75 in the bearing board 67. FIG. The positioning means includes a bearing plate 61 and a pair of protrusions 76 and 76 that gradually narrow in the front frame 2 as it extends upward, which is the shaft insertion direction, with the lower hinge mechanism 3b as a fulcrum. Thus, the bearing plate 61 is guided to the ridges 76, 76 which are narrowed by abutting the bearing plate 61 of the fixed hinge member 50 a between the ridges 76, 76 and moving down the front frame 2, The shaft hole 74 is linear, and the shaft pin 75 is reliably guided and fitted into the shaft hole 74. As described above, since the positioning means is expanded at the lower side, the other upper hinge only needs to be appropriately brought into contact between the expanded protrusions 76 and 76 without being determined at a single point. Workability for linking the mechanisms 3a is further improved. Further, the positioning means may be provided on the side surface of the front frame 2, and may further be provided on the machine frame 1 side so that the bearing plate 67 of the movable hinge member 55 a contacts. At this time, the positioning means may be provided so as to gradually narrow as it goes downward, contrary to the above. Note that the positioning means is not limited to the protrusion, and may be provided in a groove shape or in a wall shape. Further, a contact member that abuts against the positioning means may be provided without directly contacting the hinge members 50a and 55a as the positioning means.

  As described above, the present invention is not limited to the above-described embodiment. For example, the lower hinge mechanism 3b may be linked using the upper hinge mechanism 3a as a fulcrum. In the above embodiment, the large-diameter shaft hole 70 of the lower movable hinge member 55b is fitted to the support shaft 66 of the lower fixed hinge member 50b from above, but the structure of the shaft hole and the shaft pin is reversed. The support shaft 66 of the lower movable hinge member 55b is fitted into the large-diameter shaft hole 70 of the lower fixed hinge member 50b, and the small-diameter shaft portion 66a is inserted into the large-diameter shaft hole 70 as a fulcrum shaft. You may make it link the hinge mechanism 3a.

  Although the front frame 2 has been described as an opening / closing body in the embodiment, the embodiment of the upper and lower hinge mechanisms 3a, 3b can be applied to the upper / lower hinge mechanisms 12a, 12b using the opening / closing body as a mechanism plate 11. Further, the opening / closing body may be a front plate 7 provided with an upper ball receiving tray 8 for supplying a hit ball on the front surface, and can be applied to any one that can be opened and closed by a vertical hinge mechanism in a gaming machine.
