[0010]
A hitting ball supply device 11 according to an embodiment of the present invention is provided on the back side of the front plate 6. The hitting ball supply device 11 is for supplying pachinko balls stored in the hitting ball supply tray 8 one by one from the ball through holes 12 formed in the front plate 6 to the launch position 5 of the launch rail 3. The member 14 is used.
[0011]
As shown in FIG. 3, the main body 13 of the hit ball supply device 11 is formed by combining a substrate 13 a that is in close contact with the back side of the front plate 6 and a cover plate 13 b that is positioned on the side surface of the launch rail 3. The substrate 13a is provided with a sphere inlet 15 that matches the sphere through-hole 12 of the front plate 6 and a concave recess 16 that faces the sphere supply member 14, and the cover plate 13b has a sphere inlet. A supply port 18 corresponding to the launching position 5 of the launching rail 3 and a vertical spherical passage 17 communicating with 15 is provided.
[0012]
The ball supply member 14 has a three-dimensional shape having a thickness substantially equal to the passage width of the ball passage 17 of the cover plate 13b, and an arcuate ball stop portion 19 is formed at the upper end thereof. A semicircular ball receiving recess 20 is formed below. In addition, rotation support shafts 21 and 21 protrude from both sides of the upper portion, and an engagement pin 23 with a roller 22 that also serves as a weight protrudes from one side.
[0013]
Thus, the bearing portions 24 and 24 of the ball supply member 14 are formed on the rear surface side (the side in contact with the cover plate 13 b) of the substrate 13 a and on both the left and right sides of the recessed portion 16. The bearing portions 24, 24 are shelf-like horizontal receiving pieces 25, 25 on which the rotation support shafts 21, 21 of the ball supply member 14 are placed, and protruding pieces that rise vertically from the horizontal receiving pieces 25, 25. 26 and 26, the upper surface is formed in a U-shaped cross section.
[0014]
The distance between the rear surface of the substrate 13a and the projecting pieces 26, 26 is set to be approximately the same as the diameter of the rotation support shafts 21, 21 of the ball supply member 14. Further, the distance between the upper surfaces of the horizontal receiving pieces 25 and 25 and the upper ends of the projecting pieces 26 and 26 is set to a dimension that is substantially equal to the diameter dimension of the rotary support shafts 21 and 21.
[0015]
On the other hand, horizontal cover pieces 27 and 27 that close the upper surface openings of the bearing portions 24 and 24 in a state where the cover plate 13b is combined with the substrate 13a are provided at the lower ends of the cover plate 13b located on the left and right sides of the ball passage 17. Are integrally formed.
[0016]
The hitting ball supply device 11 according to one embodiment of the present invention is assembled in the following manner. As shown in FIGS. 4 and 5, first, the rotational support shafts 21 and 21 of the ball supply member 14 are inserted from the upper surface openings of the bearing portions 24 and 24 of the substrate 13 a and placed on the horizontal receiving pieces 25 and 25. Next, in this state, the front side of the cover plate 13b is brought into contact with the rear side of the substrate 13 to be integrated. As a result, as shown in FIG. 6, the upper surface openings of the bearing portions 24, 24 of the substrate 13 a are closed by the horizontal lid pieces 27, 27 of the cover plate 13 b, and the rotation support of the ball supply member 14 is supported by the bearing portions 24, 24. The shafts 21 and 21 are positioned so that the ball supply member 14 is pivotally supported. The hitting ball supply device 11 assembled as described above is brought into close contact with the back surface of the front plate 6 and is screwed 28 and 28.
[0017]
In this way, the ball supply member 14 pivotally supported by the bearing portions 24 and 24 of the substrate 13a is prevented from dropping off from the substrate 13a due to the rotation support shafts 21 and 21 being received by the projecting pieces 26 and 26. In addition, the horizontal lid pieces 27, 27 of the cover plate 13b are also prevented from moving in the vertical direction, and smooth rotation is guaranteed.
[0018]
For this reason, when the pachinko ball dirt adheres to the ball passage 17 of the hitting ball supply device 11 or the ball stop portion 19 or the ball receiving recess portion 20 of the ball supply member 14 and it is necessary to clean the cover plate 13b from the substrate 13a. Since the ball supply member 14 does not fall off the substrate 13a even if it is removed, the cleaning operation can be easily performed. Further, assembly after cleaning is facilitated because it is not necessary to support the ball supply member 14 by hand so as not to drop off.
[0019]
As shown in FIG. 7, a claw-like locking projection 34 is provided at the inner upper end of each projection piece 26, 26, and the locking projection 34 reduces the upper surface opening width of the bearing portion 24 of the ball supply member 14. By making the diameter slightly smaller than the diameter of the rotation support shaft 21, it is possible to more effectively achieve prevention of the ball supply member 14 from falling off. In the case of this embodiment, the rotation support shafts 21 and 21 of the ball supply member 14 may be applied and pushed into the upper surface opening of the bearing portion 24.
[0020]
Further, as shown in FIGS. 8 and 9, side pieces 35, 35 constituting a part of the spherical passage 17 of the cover plate 13 b are integrally formed on the rear surface side of the substrate 13 a and on both the left and right sides of the recessed portion 16. The same effect can be obtained by making the distance between the lower ends of the side pieces 35 and 35 and the upper ends of the projecting pieces 26 and 26 slightly smaller than the diameter dimension of the rotation support shafts 21 and 21 of the ball supply member 14. Can be achieved.
[0021]
As shown in FIG. 10, the hitting ball supply device 11 having the above-described configuration has a push-up portion 31 of an interlocking lever 30 pivotally supported by a shaft 29 on the front side of the game board 2 so as to be an engagement pin of the ball supply member 14. The ball supply member 14 is rotated in the vertical direction by the vertical movement of the push-up portion 31 of the interlocking lever 30. The interlocking lever 30 is integrally provided with a lever portion 32 that hangs downward from the shaft 29, and the lever portion 32 is positioned so as to be engageable with a hook rod 33 fixed to the hitting ball rod 4. Further, as shown in FIG. 11, the ball supply member 14 is urged to rotate downward (clockwise) about the rotation support shaft 21 by the engagement pin 23, and flows into the sphere passage 17 from the sphere inlet 15. The leading pachinko ball B to be received is received by the ball stop 19.
[0022]
Thus, when the hitting ball 4 is rotated to the hitting ball launch preparation position as shown in FIG. 10, the interlocking lever 30 is pivoted about the shaft 29 via the hook rod 33 and the lever portion 32 as shown in FIG. The ball supply member 14 is rotated upward (counterclockwise direction) as shown by a solid line in FIG. 12 with the rotation support shafts 21 and 21 as fulcrums. For this reason, the pachinko ball B received by the ball stopper 19 falls into the ball receiving recess 20 and is received. When the striking ball 4 rotates from this state to the firing operation position shown by the solid line in FIG. 10, the ball supply member 14 is also released from being pushed up by the lever portions 32, 32 and is moved downward (clockwise) as shown by the chain line in FIG. And the pachinko ball B of the ball receiving recess 20 is supplied from the supply port 18 to the firing position 5 of the firing rail 3. The operation of supplying the pachinko balls one by one to the launch position 5 of the launch rail 3 is performed.
[0023]
【The invention's effect】
As described above, according to the support structure of the ball supply member in the hitting ball supply apparatus for the pachinko machine according to the present invention, the substrate is provided with the bearing portion of the upper surface opening for supporting the ball supply member and the cover plate from the substrate. Since the ball supply member is prevented from falling off even if it is removed, wiping and cleaning when dirt on the pachinko ball adheres can be facilitated, and the work efficiency of the assembly work can be improved.
