[Prior art]
A game board such as a pachinko machine has a decorative sheet with a design drawing drawn on the back and is integrally joined to the front of a game board formed in a substantially square shape with wood such as veneer, and is attached with game function parts. For this purpose, a through hole is formed. Further, the back surface of the game board has a dent used for positioning a game function component attached to the back surface of the game board.
[0003]
The through hole and the depression are formed by a router processing machine. When forming through holes and depressions on the game board surface with a router machine, overlay the game board on the floor board that has a relief hole with a shape almost the same as the through hole to be formed on the game board surface, and place the floor board on the surface plate side. Then, it is placed on the surface plate, and an opening is formed in the game board surface by cutting from the surface opposite to the side on which the floorboards are overlapped. This clearance hole is provided to prevent the cutting tool from coming into contact with the surface plate when the cutting tool of the router machine penetrates the game board surface.
[0004]
[Problems to be solved by the invention]
When the game board is cut by the router processing machine, the game board is cut by a cutting tool such as a router blade, so that cutting scraps such as sawdust are generated from the game board. Most of the cutting waste is removed by air blowing by a dust collector attached to the router head covering the cutting tool.
[0005]
However, when the processed game board is removed from the floorboard and moved, or when a new board for processing is installed on the floorboard, the cutting waste adhering to the gameboard falls onto the floorboard, which causes cutting. There is a case where scraps enter between the game board surface and the floor board. In such a case, in the above-described conventional floor board, the game board surface and the floor board are closely stacked, so that the floor board is pressed by the pressing force of the clamp fixing the game board or the screwing force by the rotation of the cutting tool. When pressure is generated in a direction facing each other on the front side of the game board and the back side of the game board, an indentation (a trace generated by the pressure) is formed on the game board surface due to the cutting waste entering between the game board surface and the floor board. .
[0006]
Therefore, the present invention has been made paying attention to such an unsolved problem of the conventional technology, and is suitable for preventing the formation of indentations on the surface of the game board by cutting waste generated by cutting.

[0026]
Thereby, when the cutting waste enters between the game board surface 4 and the floor board 9, the cutting waste is accommodated in the cutting waste housing groove 34. Therefore, compared with the conventional game board surface 4 and the floor board 9, It is possible to prevent the indentation from being formed on the game board surface 4 by cutting chips that enter.
Furthermore, in this Embodiment, the length of the stacking direction of the cutting waste accommodation groove part 34 was made larger than the diameter of the cutting waste considered to be the largest among the cutting waste generated by cutting.
[0027]
As a result, it is expected that the cutting waste accommodated in the cutting waste accommodating groove 34 does not come into contact with the game board surface 4, so an indentation is formed on the game board surface 4 by the cutting waste that has entered between the game board surface 4 and the floor board 9. It can further be prevented.
Furthermore, in the present embodiment, the end portion 33a of the surface to be overlapped with the game board 4 out of the cross-sectional shape in the overlapping direction of the stepped portion formed by the cutting waste accommodating groove portion 34 has a curved shape with a predetermined curvature.

[0029]
Further, in the present embodiment, the cutting waste accommodating groove 34 is formed by carving a portion other than the peripheral edge 33 of the escape hole 32 in the overlapping direction among the portions corresponding to the game ball launching area.
As a result, when cutting waste enters between the gaming board surface 4 and the floor board 9, it is expected that most of the cutting waste is accommodated in the cutting waste storage groove 34. It is possible to further prevent the indentation from being formed on the game board surface 4 by the cutting waste that has entered between.
[0030]
In the said embodiment, the through-hole 16 respond | corresponds to the opening part of Claim 1, the escape hole 32 respond | corresponds to the escape groove part of Claim 1, 2 or 3 , and the router cutter 17 is Claim 1. It corresponds to the described cutting tool.
In the above-described embodiment, the cutting waste accommodating groove 34 is formed as a recess having the bottom surface of the bottom plate 9 as a bottom, but is not limited thereto, and may be formed as a through hole penetrating to the back surface of the bottom plate 9. .
[0031]
Moreover, in the said embodiment, although the escape hole 32 was formed as a through-hole penetrated to the back surface of the flooring board 9, you may form as a hollow which uses not only this but the back surface of the flooring board 9 as a bottom part. In this case, the length of the clearance hole 32 in the overlapping direction is long enough to prevent the router cutter 17 from coming into contact with the surface plate when the router cutter 17 of the router machine penetrates the game board surface 4. Say it.
[0032]
Further, in the above embodiment, the escape hole 32 has a substantially congruent shape with the through hole 16 to be formed on the game board surface 4, but is not limited thereto, and is more than the through hole 16 to be formed on the game board surface 4. Any shape may be used as long as it is large. The escape hole 32 also has a surface for preventing the router blade 17 from coming into contact with the floor board 9 when the router blade 17 of the router processing machine penetrates the game board surface 4. This is because if it is larger than 16, contact prevention with the floor plate 9 can be achieved. However, if the shape of the escape hole 32 is substantially the same as the through hole 16 to be formed in the game board surface 4 as in the above embodiment, the escape hole 32 is formed in the through hole 16 by the screwing force caused by the rotation of the router blade 17. Since the peripheral edge on the back side of the game board is pressed down exactly, it is possible to prevent so-called burrs from being generated in the through hole 16.
