Description

  The present invention relates to a game board provided inside a ball game machine such as a pachinko, an arrangement ball, and a sparrow ball, and more specifically, various parts such as a guide rail and a game nail (also referred to as an obstacle nail) on the game board. In the process of attaching the game board, a large number of game boards can be stably stacked in multiple stages without fear of damage or load collapse.

  As is well known, a game board of a ball game machine such as a pachinko machine is formed by molding a game board body of a predetermined size having a large and small mounting hole for attaching various parts with a synthetic resin (hereinafter referred to as a board). A main body molding process), a printed film with an appropriate pattern applied to the surface of the game board body (hereinafter referred to as a pattern application process), and then a pilot hole is formed in the game board body for planting game nails. (Hereinafter referred to as a pilot hole machining step), a number of game nails and windmill shaft nails are driven into the pilot hole by a dedicated nailing machine (hereinafter referred to as a nailing step), and a game ball is guided. Two guide rails composed of an outer rail and an inner rail are fixed by driving a fixing pin into the main body of the game board (hereinafter referred to as a rail mounting process), and thereafter game components such as various winning devices, symbol variation display devices, etc. The game board body Attaching a small mounting hole (hereinafter, referred to parts assembly step) the finished product by.

In this way, the game board becomes a finished product through a number of processes, so that a large number of semi-finished products are stacked between each process to be temporarily stocked, or a large number of semi-finished products are stacked. It will be necessary to move on board.
However, for example, if the game board main bodies that have finished the pilot hole machining process as described above are stacked, the entire surface of the lower game board main body and the entire back surface of the upper game board main body come into contact with each other. There was a risk of damage.
In addition, when the game board semi-finished products that have finished the rail mounting process are stacked, the game nails of the lower game board semi-product hit the back of the upper game board semi-finished product, and a load is applied to the game nails. There was a risk of getting crazy or scratching the back of the game board itself.
In particular, if the game board body is a game board that is molded from a transparent, colored transparent, or translucent synthetic resin and has improved decorativeness and design by transmitting light, the back surface is scratched as described above. When the scratch is attached, the transparency and translucency are impaired, and the commercial value may be impaired.

Therefore, in the invention disclosed in Patent Document 1 below, the height of the game nail (dimension that the game nail projects from the surface of the game board) is set to the height of the guide rail (dimension that the guide rail projects from the surface of the game board). When the game board is stacked, the game board is received and supported by the guide rail or a decorative member having the same height as the guide rail when the game boards are stacked, so that no load is applied to the game nail. I have to.
In addition, the invention disclosed in the following Patent Document 2 is based on the premise that the pinnails of the windmill are generally the highest, and there is a possibility that the pinnails of the windmill will hit when the game boards are stacked. By forming a recess in the back of the game board, interference between the shaft nail and the back of the game board was prevented.
Further, in the invention disclosed in Patent Document 3 below, by interposing spacers as separate parts when stacking the game boards, it is possible to prevent interference between the game boards without causing the game boards to contact each other. ing.

However, in the invention disclosed in Patent Document 1, since the height of the guide rail needs to be higher than the height of the game nail, a stainless steel plate having a width wider than that of a normal stainless steel plate must be used. Therefore, the manufacturing cost is increased, and the invention disclosed in Patent Document 1 simply stacks the game board semi-finished products on the guide rail. There was a risk of side slipping and cargo collapse.
In addition, the game board shown in Patent Document 2 is formed with the recesses as described above, so that the load of the game board stacked on top is supported by a large number of game nails on the lower game board. However, if the height of a large number of game nails is not uniform, the load may concentrate on some of the game nails, and if that happens, they may not be stacked horizontally and may collapse during movement. At the same time, there is a problem that scratches and dirt are generated on the back of the game board due to contact with the game nails. When scratches and dirt occur in this way, especially in the case of a transparent game board made of synthetic resin, transparency and translucency are impaired, so that the expected decoration effect cannot be obtained and the commercial value may be reduced. There is. In general, the game nail is driven so as to be slightly inclined with respect to the surface of the game board (an angle slightly upward in use). However, when the game nail receives a load due to stacking, There was a risk that the setting angle would go wrong.
In addition, the game board shown in Patent Document 3 has a problem that workability is poor because spacers must be arranged for each stacking.
The present invention is intended to provide a game board that can solve these problems.
