Abstract

<P>PROBLEM TO BE SOLVED: To provide a Pachinko machine equipped with a game board which can inhibit expansion, contraction or distortion accompanying change of ambient temperature without using an expensive synthetic resin. <P>SOLUTION: A game board 2 is set up with large-diameter slits 36A and 36B penetrating from the front face to the rear face, small-diameter slits 37A and 37B and a ventilator 38 and the surface area of the game board 2 is increased. Then, expansion of the game board 2 can be inhibited because the heat transferred to the game board 2 is effectively radiated from the cross sectional surfaces of the openings, especially such as the large-diameter slits 36A and 36B, the small-diameter slits 37A and 37B and the ventilator 38. Moreover, the expansion or contraction can be released inside rather than on the periphery of the game board 2 because of the formation of the large-diameter slits 36A and 36B, the small-diameter slits 37A and 37B and the ventilator 38. Therefore, the total deformation amount (the amount of expansion or contraction) can be reduced as the whole game board 2. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

  The present invention relates to a pachinko machine provided with a game board made of synthetic resin.

  In recent years, in order to improve game playability, a game board is formed of a transparent synthetic resin, and a large liquid crystal display device is installed behind the game board so that the entire game board (game area) is used as a video display screen. A pachinko machine has been devised (for example, Patent Document 1).

JP 2005-152580 A

However, game boards molded from synthetic resin are susceptible to changes in ambient temperature. For example, the surface of the liquid crystal display device expands due to the heat of the liquid crystal display device, and the gap between game nails installed in the game area changes greatly. For example, there is a possibility that a malfunction such as a game ball becoming unable to win a tulip-type electric accessory may occur. In addition, when a temperature difference occurs between the front and rear of the game board, the amount of thermal expansion between the front and rear faces of the game board is different, and the entire game board warps forward or backward. The problem becomes more prominent with the increase in the size of the liquid crystal display device to be installed.
Moreover, in solving the above problems, it is possible to adopt a synthetic resin that is not easily affected by heat, that is, not easily deformed by heat. However, such a synthetic resin is relatively expensive and has poor workability to produce a game board. Have problems such as being unsuitable.

  Therefore, the present invention has been made in view of the above problems, and a pachinko machine provided with a game board that can suppress expansion, contraction, or distortion associated with a change in ambient temperature without using an expensive synthetic resin. It is something to be offered.

In order to achieve the above object, the invention described in claim 1 of the present invention is a pachinko machine in which a game board made of a synthetic resin plate-like member in which a game area where game balls flow down is formed on the front surface. An opening that penetrates from the front surface to the rear surface of the game board is opened to increase the surface area of the game board and to dissipate heat from the game board from a cross-sectional portion of the opening.
The invention according to claim 2 is characterized in that, in the invention according to claim 1, the opening is formed in an arc shape along a circumference centering on a center of the game board.
The invention according to claim 3 is the invention according to claim 1 or 2, wherein the opening is covered with a gaming member installed in the gaming area, and an air hole communicating with the opening is provided in the gaming member. When a temperature difference occurs between the front and rear of the game board, the air flows between the front and rear of the game board through the opening and the air hole. And

According to the present invention, the surface area of the game board is increased because the game board is provided with an opening penetrating from the front surface to the rear surface. Therefore, the heat transmitted to the game board can be released particularly from the cross section of the opening, and the expansion of the game board can be suppressed. Further, by providing the opening, it is possible to escape expansion or contraction inward from the outer peripheral edge of the game board. Therefore, the deformation amount (expansion amount or contraction amount) in the entire game board can be reduced.
In addition, according to the invention described in claim 2, since the opening is formed in an arc shape along the circumference centering on the center of the game board, expansion or contraction can be easily released in the opening. It is possible to effectively suppress the occurrence of bending in the game area.
Furthermore, according to the invention described in claim 3, the opening is covered with a gaming member installed in the gaming area, and the gaming member is provided with air holes communicating with the opening, When a temperature difference occurs in the air, the air flows between the front and rear of the game board through the opening and the air hole. Therefore, for example, even if the temperature of the rear of the game board becomes higher than that of the front due to a liquid crystal display device or the like mounted on the back of the game board, the temperature difference between the rear and front of the game board is caused by the flow of air. As a result, there is no difference in deformation (expansion or contraction) between the rear surface and the front surface of the game board. Therefore, warpage occurring in the game board can be reduced.
