BACKGROUND OF THE INVENTION
The present invention relates to a drilling method for forming a through hole in a game board such as a pachinko machine using a game ball and a slot machine using a medal.
[0002]
[Prior art]
The game board of the pachinko machine has a decorative sheet with a design drawing drawn on the back and is integrally connected to the front of the game board formed of wood such as veneer, and is used to attach game functional parts. 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]
[Problems to be solved by the invention]
By the way, when forming a through hole and a recess in the game board, if the through hole is drilled from the front side of the game board, that is, the decorative sheet side, and the recess is drilled from the back side of the game board, that is, the game board side, Drilling is a two-step process, which is economically disadvantageous.
[0004]
For this reason, as shown in FIG. 5, when the through hole 20 and the recess 21 are drilled in one step from the back side of the game board 22, the drill 23 is used when the through hole 20 is formed. The cut edge of the decorative sheet 24 may be peeled off from the game board 25 and turned up. When this turning up occurs, cutting waste 26 such as sawdust enters between the turned up decorative sheet 24 and the game board 25, and the periphery of the through hole 20 of the decorative sheet 24 is on the front side of the game board 22. It will remain swelled. If the game function parts such as tulips, center bonuses, winning holes, and attackers not shown in the figure are attached to the front of the game board 22 while the decorative sheet 24 is raised, the height of the game function parts is unreasonably high. In addition, game function parts may be distorted.
[0005]
If the gaming functional parts are unreasonably high, there is a disadvantage that the glass is damaged when the gaming board 22 is assembled to a machine frame attached to the island of a pachinko store and the glass of the machine frame is closed. When the game function part has a movable part, the movable part may malfunction due to the distortion. Therefore, the cutting waste 26 that has entered between the decorative sheet 24 and the game board 25 is removed after drilling. It is removed manually, and there is a limit to reducing costs.
[0006]
In order to eliminate such inconvenience, as shown in FIG. 6, a wooden floor board 27 such as veneer is superposed on the decorative sheet 24 of the game board 22 and the punching process is performed from the back side of the game board 22. However, the floor board 27 is likely to warp due to moisture absorption, which is one of the characteristics of natural wood, and when this warpage occurs, a gap 28 is provided between the mating surfaces of the decorative sheet 24 and the floor board 27. In the gap 28, the same inconvenience as described above occurs, which is difficult to adopt.
[0007]
Accordingly, the present invention intends to provide a method for punching a game board that can prevent the decorative sheet from turning up around the through hole by limiting the material of the floorboard.
[0008]
[Means for Solving the Problems]
Hole drilled machining method of the game board according to the present invention, a router machine for forming a through hole on the game board comprising a decorative sheet drawn the design diagram that is integrally coupled to the front surface of the game board and the game board A through hole that forms a relief hole in the game board for escaping the cutting tool when penetrating the game board and receiving the decorative sheet around the through hole formed in the game board so that the decorative sheet is not peeled off from the game board decking made of hygroscopic less material provided in advance corresponding is mounted on the surface plate as a workpiece mount router machine, superimposed in contact with the game board of the decorative sheet over the floor plate and The game board is mounted, the game board and the floor board are fixed to the surface board, and the cutting tool of the router processing machine descends while rotating from the top of the game board to cut through holes from the game board side to the game board. to form Te With escape so as not to cut the floor plate captured by the escape hole is gaming board penetration portion of the cutting tool, that is received by the escape hole around the floor plate so that the decorative sheet around the through hole is not peeled off from the gaming board It is a feature. According to the drilling method for a game board according to the present invention, the use of a base plate made of a material having a low hygroscopic property causes less warpage due to a change in humidity in the base plate, so that a cutting tool that descends while rotating is a game. When a through-hole is formed in the board and the decorative sheet is pulled out , the laying board receives the entire area around the through-hole of the decorative sheet, and can reliably prevent the decorative sheet around the through-hole from being peeled off from the game board . The part that penetrates the game board is taken into the escape hole and escapes so as not to cut the floorboard, so the cutting tool does not receive excessive external force from the floorboard, the durability of the cutting tool improves, and the floorboard is used repeatedly If it can, the cutting tool to form the so formed by cutting a game board into the through hole from the side of the game board is lowered while being rotated from the upper side of the game board, the depression on the back side of the game board , There is no need to change the procedure of holes drilled processing can be appropriately hole drilled processed and recesses and the through-hole with a small step. If the escape hole has the same shape as the through hole, the decorative sheet around the through hole can be further prevented from peeling off from the game board. If the escape hole is a hole that penetrates the laying plate, cutting waste generated in the process of cutting the through hole by the cutting tool can be released to the lower side of the laying plate.

The other positioning hole 6 is located at the intersection of the distance D3 from the lower edge of the game board 4 and the distance D4 from the side edge of the game board 4, and the dimensions of the distances D1 to D4 are D1 <D2 <. The relationship is D4 <D3.
[0016]
In addition, the floor board 9 is formed in a substantially congruent square shape with the game board 4 by either a thermosetting synthetic resin such as Bakelite (trademark) or a chemically treated wood such as acetylation as a material having low hygroscopicity. . The base plate 9 is coaxially formed with positioning holes 10 and 11 having the same shape as the positioning holes 5 and 6 of the game board 4, and the game board 4 is cut from the back side thereof by a drill or end mill which will be described later. A clearance hole 12 having the same shape as a plurality of through-holes 16 to be described later that are cut using the tool 17 is formed coaxially.
[0017]
The positioning holes 10 and 11 formed in the floor board 9 are diagonally arranged on both sides of the corner of the floor board 9 with one diagonal line L2 as a boundary, and like the positioning holes 5 and 6 of the game board 4, The positioning hole 10 is located at the intersection of the distance D1 from the upper edge of the base plate 9 and the distance D2 from the side edge of the base plate 9, and the other positioning hole 11 is located between the distance D3 from the lower edge of the base plate 9 and the base plate 9. It is located at the intersection with the distance D4 from the side edge, and the gaming board 4 can be positioned and mounted on the floor board 9 without making a mistake in the vertical relationship due to the relationship between these dimensions D1 to D4.
[0018]
According to this embodiment, when the game board 4 turned upside down is overlapped with the floor board 9 and the plurality of through holes 16 are cut from the back side of the game board 4, that is, the game board 2 side, it is called a router processing machine. Since a drilling machine having a numerical control function is used, as shown in FIG. 1, a plurality of positioning holes 10 and 11 of the base plate 9 are projected on a surface plate 13 as a work mounting base of the router machine. After the base plate 9 is mounted on the surface plate 13 of the router processing machine, the positioning holes 5 and 6 of the game board 4 are opened with the game board 4 turned upside down. Fitting and mounting from above the positioning pins 14 and 15 of the router machine protruding above the positioning holes 10 and 11 of the floor board 9, the front side of the game board 4, that is, the decorative sheet 1 is superimposed on the floor board 9, Add a router to the periphery of the game board 4 from above By pressing in an unillustrated bracket of the machine, fixed to the base 13 in a state of superposition of both the game board 4 and decking 9.
