Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a pachinko machine in which an inner frame for mounting a game board and a glass frame hinged to be openable on the front surface thereof are formed of a synthetic resin, and more specifically, an illegal operation such as a piano wire or a thin plastic plate through a gap between them. The present invention relates to a pachinko machine capable of preventing an illegal act of entering a member inside.
[0002]
[Prior art]
In general pachinko machines, a frame-shaped inner frame to which a game board is attached is hinged on the front side of the outer frame so that it can be opened and closed, and a glass frame equipped with glass is opened and closed on the front side of the inner frame. It is worn. In recent pachinko machines, the inner frame and the glass frame are often molded with a synthetic resin in order to improve the quality of the appearance and the design.
[0003]
[Problems to be solved by the invention]
However, when molded with synthetic resin, the strength of the frame itself is weakened, and in particular, the glass frame is a heavy object including two large-sized glasses, so that the rigidity is increased so that the entire body is not bent or twisted. There is a need. Therefore, conventionally, reinforcing means such as providing a reinforcing sheet metal is provided on the outer periphery of the glass frame. As described above, in the inner frame and the glass frame made of synthetic resin, it is necessary to suppress the entire bending, twisting and the like, but it is also desired that the outer peripheral edge portion is not deformed or damaged by an external force. That is, when the outer peripheral edge portion is easily deformed, a so-called goto action is possible in which a piano wire or a thin plastic plate is inserted from a gap generated thereby to illegally acquire a prize ball.
[0004]
Further, as shown in FIG. 6, an avoidance space is formed in the inner frame 80 so that the outer end portion 82 </ b> A of the glass frame 82 does not interfere when the glass frame 82 rotates about the hinge shaft 84. When the glass frame 82 is closed, there may be a gap W between the inner frame 80 and the glass frame 82 due to the avoidance space. Therefore, the inner frame 80 is provided with a covering member 78 protruding forward so as to cover the gap W from the outer side, but the inner frame 80 (covering member 78) and the glass frame 82 are combined. If it is made of resin, it can be deformed so as to widen the gap W between the covering member 78 and the glass frame 82, and from this, it becomes possible to perform a go-to action that allows the piano wire P or the like to enter the pachinko machine.
[0005]
The inner frame is hinged to an outer frame made of wood or the like so as to be openable and closable, and is locked by a locking device. And conventionally, there was no gap between the outer frame and the inner frame by being locked by the locking device. However, when the inner frame is made of synthetic resin as described above, a gap may be generated due to distortion or the like. In addition, when an integrated dish attached with a ball receiving assembly or launching handle for storing pachinko balls is hinged to the inner frame so as to be openable and closable below the glass frame, the boundary between the integrated dish and the glass frame, That is, there was a considerable gap between the upper edge of the integrated dish and the lower edge of the glass frame. If such a gap exists, there is a problem that the above-described fraud is easily performed.
[0006]
Therefore, in view of the above circumstances, the present invention prevents an illegal act of causing an unauthorized operation member such as a piano wire or a thin plastic plate to enter the inside even in a pachinko machine having a synthetic resin inner frame and a glass frame. The purpose is to obtain a pachinko machine that can do.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, a pachinko machine according to claim 1 according to the present invention includes a synthetic resin inner frame provided with a game board, and a glass unit including a glass covering a front surface of the game board. A synthetic resin glass provided on the front side of the inner frame so as to be openable and closable via a hinge portion, having an opening in the center, and mounting the glass unit on the inner surface of the game board so as to close the opening. A pachinko machine having a frame, and a tip that comes into contact with an inner surface of the inner frame at a predetermined pressure when the glass frame is closed at a side edge of the hinge portion of the glass frame.

That is, since the leaf spring can be brought into contact with the inner frame with a predetermined pressure, the gap can be reliably closed even if there is a molding error in the inner frame or the glass frame.
[0009]
Therefore, even if an unauthorized operation member such as a piano wire or a thin plastic plate enters the pachinko machine through the gap between the inner frame and the glass frame formed on the hinge side, the unauthorized operation member comes into contact with the leaf spring. Any further entry is blocked. In the unlikely event that the unauthorized operation member slips between the inner frame and the leaf spring and further enters the pachinko machine, a convex portion is projected at that position, so the unauthorized operation member It abuts against the convex part and further entry is prevented. Thus, fraud is reliably prevented.
[0010]
In addition, since the tip of the leaf spring is substantially cylindrical, when the glass frame is opened and closed, there is no risk of injury due to contact with the leaf spring and damage to the inner frame. There are no defects.
[0011]
In addition, in a pachinko machine equipped with an integrated dish that can be opened and closed via a hinge part on the inner frame below the glass frame, a step-like engagement is provided on the back side of the upper edge of the integrated dish. the engagement portion is continuously arranged, when closing the glass frame, by the lower edge of the glass frame is engaged with the engaging portion, it is bent in a stepwise manner between the lower edge portion and the engaging portion maze You may make it the structure in which a structure is formed.
[0012]
According to this , even if an unauthorized operation member such as a piano wire or a thin plastic plate enters the pachinko machine from the gap between the upper edge of the integrated dish and the lower edge of the glass frame, the gap is stepped. Since it has a maze structure that bends, the unauthorized operation member is prevented from entering the pachinko machine. Therefore, fraud is reliably prevented.
[0013]
At this time, the engaging portion, and a bag portion that is continuous with the gap between the integral tray and glass frame, in the upper side of the bag portion, and a stepped portion lower edge of the glass frame is engaged, the It is preferable to have .
[0014]
According to this , even if an unauthorized operation member such as a piano wire or a thin plastic plate enters the pachinko machine from the gap between the upper edge of the integrated dish and the lower edge of the glass frame, the unauthorized operation member is It will only be inserted into the bag. Therefore, the unauthorized operation member is reliably prevented from entering the pachinko machine.

The space continuous upward from the gap U with the integrated dish 30 is configured to be a non-linear space (so as to have a maze structure). Therefore, even if the piano wire P or the like is entered from the gap U between the glass frame 20 and the integrated dish 30, the piano wire P or the like is merely inserted into the bag portion 74A formed by the engaging portion 74, and more. Is prevented from entering. That is, since the engaging portion 74 is formed in a stepped shape toward the upper front, it is impossible for the piano wire P or the like to pass through the space formed in the stepped shape. Definitely blocked.
[0033]
The operation of the pachinko machine 10 configured as described above will be further described. First, as shown in FIG. 2, the pachinko machine 10 starts from a gap W between the glass frame 20 and the inner frame 14 generated on the hinge portion side. Even if the piano wire P is caused to enter the inside, the piano wire P comes into contact with the leaf spring 60 and further entry is prevented. In addition, even if the piano wire P passes through between the inner surface of the inner frame 14 and the tip of the leaf spring 60 and further enters the interior, the projection 62 is projected at that position, so the piano wire P Abuts against the convex portion 62, and further entry is prevented. Therefore, fraud is reliably prevented.
[0034]
Further, as shown in FIG. 4, even if an attempt is made to enter the piano wire P into the pachinko machine 10 through the gap S between the outer frame 12 and the inner frame 14 generated on the locking device 16 side, the piano wire P is not connected to the inner frame 14. Since it abuts against the rising wall portion 70A of the plate 70 of the locking device 16 disposed on the back surface, further entry is impossible and entry into the interior is reliably prevented. Therefore, fraud can be prevented.
[0035]
Furthermore, as shown in FIG. 5, even if an attempt is made to enter the piano wire P into the pachinko machine 10 through the gap U between the glass frame 20 on the front side and the integrated dish 30, a rib is formed on the inner side of the upper edge of the integrated dish 30. 72 is extended, and further, a staircase-like engaging portion 74 is continuously connected from the rear end portion toward the upper front, and the side surface 32B of the glass frame 20 is engaged with the stepped portion 74B. The space that becomes the entry path to the inside of the piano wire P has a maze structure that bends in a staircase shape, and it is impossible to enter the piano wire P while bending it. It is only inserted into 74A, and entry into the interior is reliably prevented. Therefore, fraud can be prevented.
[0036]
