One end side (the left end side in FIG. 1) of the main set 36 is rotatably attached to the mounting frame 13 via two upper and lower hinges 43, and the one end side serves as a rotation fulcrum. The mounting frame 13 is rotatable. The main set 36 is fixed to the mounting frame 13 by locking the two mounting hooks 44 at the other end (the right end in FIG. 1) at the upper end and the lower end. Has become.

Here, the mounting structure on the other end side of the main set 36 will be described in detail. The part of the upper end 45 on the other end side facing the mounting frame 13 is also shown in FIG. In addition, for example, two pin-shaped positioning projections 46 are integrally provided at predetermined intervals. The shape of each positioning protrusion 46 is formed in a taper shape (conical trapezoidal shape) and is tapered. In this case, each of the positioning projections 46 is formed integrally with the main set 36. A mounting hook 44 is rotatably provided on the upper end portion 45 of the main set 36 with a shaft 47 (see FIG. 3) as a fulcrum. The attachment hook 44 is made of metal, for example, and is composed of a hook main body 48 and a knob 49 having a U-shaped cross section. In this case, the protruding piece on the left side in FIG. 4 of the hook body 48 of the mounting hook 44 constitutes the engaging piece 48a. As shown in FIG. 1, a fan-shaped through hole 50 is formed at the lower end portion on the other end side of the main set 36. At the lower edge of the through hole 50, a mounting hook 44 having the same structure as the mounting hook 44 described above is rotatably provided with a shaft 51 (see FIG. 3) as a pivot.

On the other hand, two positioning holes 52 into which the above-mentioned two positioning protrusions 46 are fitted are formed in a portion of the upper end of the mounting frame 13 facing the main set 36. Further, a fitting hole 53 into which the engaging piece portion 48a of the upper mounting hook 44 is fitted is formed in the upper end surface portion of the mounting frame 13. The fitting hole 53 constitutes an engaging portion. Further, a projecting piece portion 54 is provided so as to project rearward at the central portion of the lower end portion of the mounting frame 13, and the engaging piece portion 48a of the lower mounting hook 44 is fitted to this projecting piece portion 54. A hole 55 is formed. The fitting hole 55 constitutes an engaging portion.

In the above configuration, when the main set 36 is attached to the attachment frame 13 of the main body frame 14, first, as shown in FIG. 1, one end of the main set 36 is rotatably pivoted via a hinge 43. Support. At this time, the two mounting hooks 44 of the main set 36 are rotated in the non-locking direction (upward). In this state, the main set 36 is rotated with the hinge 43 as a fulcrum of rotation so as to be brought into contact with the rear surface of the mounting frame 13. At this time, positioning is performed by fitting the positioning projection 46 integrally formed with the main set 36 into the positioning hole 52 formed in the mounting frame 13. By this positioning, it is possible to reliably prevent the main set 36 from shifting in the vertical direction (especially downward). In this case, since the positioning projection 46 is formed in a tapered shape to be tapered, when the positioning projection 46 is fitted into the positioning hole 52 of the mounting frame 13, the tip end of the positioning projection 46 is fitted. It becomes easy to fit the positioning hole 52 into the positioning hole 52, and when the positioning projection 52 is fitted into the positioning hole 52 up to the base end part, both of them fit in a close contact state. Therefore, the positioning accuracy of the main set 36 can be increased. In this case, sufficient positioning accuracy can be obtained simply by disposing the positioning protrusion 46 on the upper end of the mounting frame 13 on the other end side.

Thereafter, by rotating the two mounting hooks 44 in the locking direction (downward), the engaging piece portions 48 a of the respective mounting hooks 44 are fitted into the fitting holes formed in the mounting frame 13. Fit to 53, 55. As a result, the main set 36 is firmly attached and fixed to the mounting frame 13, that is, the main body frame 14.

In this case, since the positioning holes 52 and the fitting holes 53 and 55 are only formed in the mounting frame 13, it is not necessary to mount separate parts, so that the number of parts is reduced and the mounting frame 13 itself is assembled. Work is greatly simplified. However, although it is necessary to provide the positioning convex portion 46 on the main set 36 side, in the above configuration, since the positioning convex portion 46 is integrally formed on the main set 36, the number of parts does not increase and the assembly is easy. No hassle.

Further, in the above embodiment, since the two positioning protrusions 46 are formed in a tapered shape and are tapered, the positioning protrusions 46 are fitted into the positioning holes 52 of the mounting frame 13. In doing so, it becomes easier to fit the tip end of the positioning projection 46 into the positioning hole 52, and when the positioning projection 52 is fitted into the positioning hole 52 as well, the two will fit together closely. become. Therefore, the positioning accuracy of the main set 36 can be increased. Sufficient positioning accuracy can be obtained simply by disposing the positioning protrusion 46 on the upper end of the mounting frame 13.

Further, in the above-described embodiment, since the two positioning protrusions 46 are arranged at a certain distance, the positioning strength against external force is increased, and the main set 36 is stored by its own weight (particularly stored in the ball tank 40). It is possible to reliably prevent the pachinko ball from moving upward and downward (especially downward) due to the heavy weight of the pachinko ball. As a result, the number of mounting hooks 44 for mounting the main set 36 can be reduced to two, that is, the number of locking points for locking the main set 36 to the mounting plate 13 can be reduced. Therefore, the mounting structure of the main set 36 can be simplified accordingly.

In the above embodiment, the positioning protrusion 46 (and the positioning hole 52) is provided only on the upper end side of the main set 36 (and the upper end side of the mounting frame 13). A positioning protrusion (and a positioning hole) may be provided on the lower end side of 36 (and the lower end side of the mounting frame 13). Further, the number of the positioning projections 46 is not limited to two, and one or three or more may be provided, and the positions where they are arranged may be appropriately determined. Furthermore, the fitting holes 53 and 55 are formed as the engaging portions in the mounting frame 13, but instead of this, the engaging piece portion 48a of the mounting hook 44 is engaged with the front surface portion of the mounting frame 13. Alternatively, the mounting frame 44 and the main set 36 may be sandwiched between the mounting hooks 44. In this case, the front surface portion of the mounting frame 13 constitutes an engaging portion.
