[Industrial application fields]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shaft support structure for a ball removal device provided on a curved rail of a pachinko machine, and more particularly to a shaft support structure for a pair of a movable bottom plate and an engagement lever that allow the ball removal device to be detached after the assembly of the curve rail. It is.
[0002]
[Prior art]
Conventionally, a curved rail of a pachinko machine has a plurality of spherical flow paths in which a spherical flow path having a partition wall on each side edge is sequentially stacked on an outer plate, and a back plate having a spherical flow path is finally stacked. The curved rail is assembled, and the curved rail is provided with a ball pulling device having a pair of a movable bottom plate and an engaging lever, and a broken ball detecting device built in to complete the assembly of the curved rail. Yes.
Further, in the ball removing device, the movable bottom plate is incorporated into the curved rail by being inserted into the shaft provided on the curved rail, and the engaging lever is pivotally attached to the shaft provided on the mechanism plate. (See Japanese Utility Model Publication No. 4-13023).
[0003]
[Problems to be solved by the invention]
As shown in FIG. 11, the ball punching device described in the prior art has a pair of a movable bottom plate 100 and an engagement lever 101. The movable bottom plate 100 has a substantially U shape, and a cylindrical shaft portion is formed at the bent portion. The engaging lever 101 is formed by integral molding with a synthetic resin material having a cylindrical shaft portion 103 at the rotation end, and is formed by integral molding with a synthetic resin material. The engagement lever 101 is pivotally attached to a predetermined portion of the curve rail by rotatably inserting metal shafts 104 and 105 into the respective cylindrical shaft portions 102 and 103. In the step of incorporating the movable bottom plate 100 and the engaging lever 101 of the ball removal device into the curve rail, one end of the metal shafts 104 and 105 is inserted into the bearings 107 and 108 provided on the outer plate 106 of the curve rail. The cylindrical shaft portions 102 and 103 of the movable bottom plate 100 and the engaging lever 101 are inserted into the shafts 104 and 105, respectively, and other parts, that is, the shafts 104 and 105 are inserted in advance. The assembly of the curve rail is completed by overlapping a plurality of spherical flow paths (not shown) having partition walls or incorporating a broken ball detection device (not shown). In such a curved rail assembly structure, when the movable bottom plate 100 or the engaging lever 101 needs to be replaced after the completion of the curved rail assembly due to malfunction or the like, the curved rail remains assembled. In this case, the movable bottom plate 100 or the engagement lever 101 alone cannot be freely detached or attached. In this case, the curve rail must be disassembled, the movable plate 100 or the engagement lever 101 must be replaced, and the curve can be changed again. There was an inconvenience that the rails had to be reassembled.
[0004]
Further, using the shafts 104 and 105 prepared separately for mounting the movable bottom plate 100 and the engaging lever 101 on the curve rail not only increases the number of parts, but also provides the shafts 104 and 105 in advance in the assembly process. If this is done, the shafts 104 and 105 interfere with the work of stacking other parts, that is, a plurality of spherical flow paths provided with partition walls, or incorporating a broken ball detection device, and assembling work of the curve rail In addition, the shafts 104 and 105 must have a desired rigidity so that the movable bottom plate 100 does not bend due to the weight pressure of the sphere. The use of a metallic shaft is unavoidable, but the metallic shaft is expensive and uneconomical.
[0005]
The present invention has been made in view of the above points. The purpose of the present invention is to complete the assembly of the curve rail at the time when a plurality of spherical flow paths provided with partition walls and a broken ball detection device are incorporated. After completion of the assembly in this state, the movable bottom plate and the engagement lever can be attached to and detached from the curve rail, the number of parts is reduced, the shaft function is excellent, the assembly is simplified and the workability is improved. The shaft support structure of the apparatus is provided.
[0006]
[Means for Solving the Problems ]
