  In the conventional structure, since the game board is mounted on the back side of the inner frame so that the rear part protrudes, the reinforcing plate provided on the back side of the side edge of the inner frame prevents illegal acts against the back side of the game board. I try to prevent it.

  However, when the ball game machine is mounted on the island facility, the front side protrudes from the island facility to the front side from the side edge of the inner frame, so the gap between the inner frame and the front glass door is likely to be subject to fraud. Despite the tendency, the conventional structure does not take measures against this point. That is, in the conventional inner frame, the side edge portion of the inner frame is bent in an arc shape to the front side to ensure rigidity, but there is a large gap between the side edge portion and the glass door, and from the gap There is a possibility that fraud such as bending a game nail on the game board side by inserting an unauthorized member such as a piano wire or a cell board may occur.

  Particularly in recent ball game machines, the width of the left and right side portions of the inner frame and the glass door has become very narrow with the expansion of the game area of the game board. Therefore, on the base side without locking means, the strength of the inner frame and the left and right sides of the glass door also decreases, and the passage width when inserting an unauthorized member is short, so if there is even a slight gap between them, that part Therefore, it becomes easy to insert an unauthorized member into the game area, and it is easy to invite an illegal act.

  The present invention provides a gaming machine capable of improving the rigidity of the base side of the inner frame with a simple structure and preventing illegal acts that protrude through the gap between the inner frame and the open / close door in view of such conventional problems. The purpose is to do.

In the gaming machine provided with the opening and closing doors 6 and 7 pivotably attached to the frame 3, the inner frame 3 is provided with a frame reinforcing plate 44 for reinforcing the base side on the substantially upper and lower sides of the inner frame 3. The frame reinforcing plate 44 has a front overlapping portion 47 that is bent inward in the left-right direction from the front end of the side wall portion 46 and that corresponds to substantially the entire vertical length of the open / close doors 6, 7. Has a rear overlapping portion 61 that is superposed on the back side of the front overlapping portion 47 when the opening and closing doors 6 and 7 are closed at substantially the entire length of the upper and lower sides on the base side.

  The frame reinforcing plate 44 is in contact with the rear surface of the base frame side of the inner frame 3 on the front side of the outer frame 2, and the outer edge of the inner frame 3 from the left and right outer ends of the rear wall portion 45. The side wall portion 46 bent forward along the side surface and the front overlapping portion 47 bent inward from the front end side of the side wall portion 46 may be integrally made of sheet metal.

  Door reinforcement plates 57 and 69 that reinforce at least the base side thereof are provided on the rear surfaces of the opening and closing doors 6 and 7, and the rear overlapping portion 61 is integrally formed at the ends of the door reinforcement plates 57 and 69.

Since the rear overlapping portions 61 and 71 that are superposed on the back side of the front overlapping portion 47 when they are closed are substantially full length above and below the base portion, It becomes very difficult to insert an unauthorized member such as a piano wire or a cell plate from between the inner frame 3 and the glass door 6 and the front door 7, and the unauthorized member is inserted from this portion to play the game nail of the game board 10. It is possible to easily prevent a fraudulent act such as bending a bend or improperly acting on the launching means 18 with a simple structure.

  Particularly, since the rear overlapping portions 61 and 71 on the glass door 6 and front door 7 side are superposed on the front overlapping portion 47 of the frame reinforcing plate 44 of the inner frame 3 from the back side, Even if an external force such as pulling the front side between the upper and lower hinges 8 and 9 is applied to the base side, the rear overlapping portions 61 and 71 only engage with the front overlapping portion 47 of the frame reinforcing plate 44. Further, there is no fear that the base side of the glass door 6 and the front door 7 will be deformed, and it is possible to reliably prevent damage to the base side of the glass door 6 and the front door 7 as well as fraud.

  In addition, the frame reinforcing plate 44 is in contact with the rear wall 45 on the front side of the outer frame 2 and in contact with the rear surface on the base side of the inner frame 3, and along the outer surface of the inner frame 3 from the outer edge in the left-right direction of the rear wall 45 Since the side wall portion 46 bent to the front side and the front overlapping portion 47 bent inward from the front end side of the side wall portion 46 are integrally made of sheet metal, the strength of the frame reinforcing plate 44 itself is increased. While using the thin frame reinforcing plate 44, a sufficient reinforcing effect can be obtained.

  The door reinforcing plates 57 and 69 are at least on the base side of the rear surface of the glass door 6 and the front door 7, and the rear overlapping portions 61 are integrally formed at the ends of the door reinforcing plates 57 and 69. The strength of the base side of the front door 7 is also improved.

  FIG. 11 illustrates a second embodiment of the present invention. In this embodiment, within the range in which the opening and closing of the glass door 6 and the front door 7 around the hinge shaft 54 is not impaired, the front overlapping portion 47 of the frame reinforcing plate 44 faces the inner rearward direction from the front end of the side wall portion 46. 44 rear overlapping portions 61 are bent at an acute angle from the rear end of the bent portion 60 toward the outer front side. In this way, the dimension from the center of the hinge shaft 54 to the rear overlapping part 61 can be shortened, and the dimension in the front-rear direction on the base side of the inner frame 3 can be increased unless there is interference with other components. There is.

  FIG. 12 illustrates a third embodiment of the present invention. In this embodiment, the rear wall portion 45 of the frame reinforcing plate 44 of the inner frame 3 is formed in an arc shape centering on the hinge shaft 54, and the engaging portion 73 at the inner end of the rear wall portion 45 is the inner frame 3. The front side frame portion 31 is engaged with the engagement groove 74 on the back surface side. In this way, the gap between the outer frame 2 and the base of the inner frame 3 can be reduced. The side wall portion 46 and the front overlapping portion 47 of the frame reinforcing plate 44, and the bent portion 60 and the rear overlapping portion 61 of the door reinforcing plate 57 are each configured in a J shape.

  FIG. 13 illustrates a fourth embodiment of the present invention. In this embodiment, the frame reinforcing plate 44 has an embedded portion 75, and the embedded portion 75 is embedded in the front frame portion 31 of the inner frame 3. A hole 76 is formed in the embedded portion 75. Thus, the frame reinforcing plate 44 can be molded with a synthetic resin material in a state where the embedded portion 75 is embedded in the front frame portion 31 on the base side of the inner frame 3.

  As mentioned above, although the Example of this invention was explained in full detail, this invention is not limited to these Examples, A various change is possible in the range which does not deviate from the meaning of this invention. For example, in the embodiment, the frame reinforcing plate 44 has a cross-sectional shape that is substantially U-shaped or substantially L-shaped, but the frame reinforcing plate 44 has a side wall portion 46 and a front overlapping portion 47, It is sufficient if the door reinforcing plate 57 has the rear overlapping portion 61. Accordingly, the cross section of the frame reinforcing plate 44 may have another shape.

  The door reinforcing plate 57 of the glass door 6 has a size corresponding to substantially the entire door frame 55, and the rear overlapping portion 61 is integrally provided on the door reinforcing plate 57, but corresponds to substantially the entire door frame 55. Apart from this, the rear overlapping portion 61 may be provided on another reinforcing plate that reinforces the base side of the glass door 6. Further, in the case where the door frame 55 of the glass door 6 is a sheet metal, the rear overlapping portion 61 may be provided on the door frame 55 itself without providing a separate reinforcing plate. Further, the post-polymerization portion 61 may be provided integrally with a synthetic resin frame.

  In each embodiment, the glass door 6 and the front door 7 are illustrated as the opening and closing doors, but other doors may be used. In addition, the present invention is not limited to pachinko machines, but can be similarly applied to various ball game machines such as arrange ball machines, sparrow ball game machines, and other game machines.
