  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a front transparent plate mounting structure and a gaming machine, and more particularly to a front transparent plate mounting structure and the like that can effectively prevent unauthorized gaming performed by opening a decorative frame in a gaming machine such as a pachinko machine. .

  In a ball game machine such as a pachinko machine, a ball that has been shot down flows on the surface of the game board, and in the course of the flow, the ball rolls while colliding with a gauge (also called a nail) or impeller on the game board surface. Then the flow direction changes. As a result, if a ball wins at various winning holes arranged on the surface of the game board, a predetermined prize ball is paid out. On the other hand, if a ball flows into the out port without winning any prize hole, no prize ball is paid out. . The player enjoys the game by demonstrating his / her skill in the ball or using the chance of the ball flowing down and expecting to win a prize and give away a prize ball.

  Such a pachinko machine is configured so that the entire device is surrounded by a plurality of frames, smooth flow of the ball, prevention of illegal gaming by the player, improved installation in the pachinko hall, improved maintainability, gaming Various functions such as directing are realized.

  Specifically, the housing frame is configured to surround mainly the upper and lower surfaces and the left and right side surfaces of the entire pachinko machine. This casing frame is generally a frame body made of wood or resin, and has a substantially rectangular parallelepiped shape as a whole, and its front and rear surface portions are largely open to have a substantially cylindrical shape. It has a “cylinder” shape.

  A machine frame is arranged in front of the housing frame, that is, on the player side. This machine frame is a frame body for holding the game board, and is pivotally supported by the casing frame so that it can be opened and closed and locked. Further, the machine frame holds a back mechanism board including a prize ball payout device, a winning ball processing device, and various paths of balls on the back side thereof.

  A decorative frame is arranged in front of the machine frame. This decorative frame is a frame disposed at a position directly facing the player. Generally, an opening for visually recognizing the game board is formed near the center, and a transparent plate such as a front glass is formed in the opening. keeping. Further, the decorative frame holds a decorative member provided with a product for producing a game, a color and a pattern around the front glass, and an electric lamp, a sound effect generating speaker, and the like.

  These frames exhibit a function of preventing illegal games from the outside alone or in cooperation. In other words, the decorative frame and the front glass cooperate to cover the front surface of the game board and prevent fraud from the front surface. And each frame (a housing frame, a machine frame, and a decoration frame) cooperates to surround the left and right side surfaces and the top surface of the pachinko machine, and prevents fraud from the left and right side surfaces and the top surface.

  For example, Patent Documents 1 and 2 disclose such a decorative frame and front glass mounting structure. This Patent Document 1 discloses a structure in which a front glass is slid from a side and inserted into a glass frame that can swing and open with one side end as a fulcrum. Patent Document 2 discloses a glass frame that can be engaged with and detached from the front frame.

  However, the ball on the surface of the game board is illegally guided to the winning opening or the winning by opening the decorative frame without permission or by inserting a wire or the like through the gap between the decorative frame and the machine frame (or the housing frame). There is a case where an illegal game for illegally operating the device is performed. When such an illegal game is performed, not only does the pachinko hall suffer a disadvantage, but other players cannot play the game with peace of mind.

  In other words, for pachinko halls, there are cases in which there are great disadvantages such as damage caused by unauthorized player acquisition of illegal prize balls, damage to pachinko machines due to the opening of decorative frames, and the increase of shop assistants for fraud monitoring. On the other hand, for other players, there may be undue disadvantages such as a decrease in the number of prize balls due to illegal player's acquisition of illegal prize balls, and psychological anxiety about the possibility of being mistaken for illegal players. There is.

  Therefore, there has been a need for a structure that does not allow access to the game board surface even if the decorative frame is opened or a wire or the like is inserted from the gap, and a pachinko machine having such a structure is impossible.

  However, in the thing disclosed in Patent Document 1, the front glass is slid into a glass frame (corresponding to a decorative frame), and the front glass opens and closes together with the glass frame. Unauthorized gaming can not be prevented. Moreover, in the thing disclosed in Patent Document 2, the glass frame can be disengaged from the front frame (corresponding to a decorative frame), but the glass frame is locked to the front frame side during normal gaming. Therefore, it still lacks the ability to prevent the above-mentioned fraudulent game.

  The present invention has been made in view of the above circumstances, and even if the decorative frame is opened or a wire or the like is inserted from the gap between the decorative frame and another frame, the game board surface cannot be accessed. It is an exemplary problem to provide a front transparent plate mounting structure and a gaming machine having the structure that can effectively prevent an illegal game performed by opening.

  In order to solve the above problems, a front transparent plate mounting structure as an exemplary aspect of the present invention includes a decorative member that is pivotally supported so as to be openable and closable with respect to the game board and decorates the periphery of the front of the game board.

It is pivotally supported so that it can be opened and closed, and a locking claw for preventing the opening of the front transparent plate is provided on either the game board or the machine frame holding the game board.

  The front transparent plate is pivotally supported so as to be openable and closable with respect to the game board independently of the decorative frame, and a locking claw for preventing the opening is provided on the game board or machine frame. Even when the decorative frame is opened illegally, the front transparent plate can be kept closed with respect to the game board. Therefore, even if the decoration frame is illegally opened or a wire or the like enters from a gap between the decoration frame and another frame body, the player cannot access the game board illegally.

  Here, the front or front means a direction on the player side when viewed from the gaming machine. “The front transparent plate is independent of the decorative frame” means that the opening and closing of the front transparent plate is not affected by the opening and closing of the decorative frame. That is, it means a state in which the front transparent plate can be kept closed even when the decorative frame is opened. Further, the front transparent plate is generally made of glass, but it is sufficient to satisfy the function of preventing access to the game board surface from the front of the player and the function of ensuring the player's visibility. May be used as a material.

Thereby, when opening a front transparent board, it operate | moves so that each link member may be folded, and a front transparent board stands upright ahead of a game board. Since the opening and closing of the front transparent plate can be realized by a simple link structure, the structure can be simplified, the degree of freedom in space design can be increased, and the component cost can be reduced. Since the rotational moment of the front transparent plate that accompanies opening and closing can be reduced, the opening and closing operation can be smoothed, and the damage when colliding with other members can be reduced to a minimum.

  The position of the shaft support portion of the decorative frame and the position of the rotation shaft of the first link member may be opposite to each other in the width direction of the game board. Since the shaft support and the rotation shaft are parts that hold the decorative frame and the front transparent plate in an operable manner, a plurality of parts and parts with high strength are required. However, if each of them is arranged on the opposite side in the width direction of the game board (that is, the left and right opposite sides), the mutual components do not interfere with each other, so that a space for the arrangement is created and the degree of freedom in design increases.

  A gaming machine as another exemplary aspect of the present invention includes a housing frame that surrounds the entire gaming machine, a gaming board that produces a game with a ball, and a gaming board that can be opened and closed in front of the housing frame. A machine frame that is pivotally supported, a front transparent plate that is spaced apart from the game board by a certain distance, the mounting structure for mounting the front transparent board, and a decorative member that decorates the front periphery of the game board It has a decoration frame which is held in front of the housing frame and can be opened and closed on the front side, and a storage tray for storing a sphere.
