BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko machine, which is effective in preventing fraudulent activity performed by a player inserting a wire or the like through a gap between mating surfaces of an outer frame and a front frame.

[0002]

2. Description of the Related Art In a pachinko machine equipped with a front frame to which main components such as a game board are attached and an outer frame to which the front frame is openably and closably mounted, a front frame is closed. If there is a gap in the mating surface between the lower end of the front frame and the curtain plate mounted on the lower front surface of the outer frame, there is a risk that the player will insert wire or the like through the gap and perform an illegal act. Therefore, various proposals have heretofore been made in order to prevent the above-mentioned fraudulent acts.
No. 1-232009 can be mentioned. In the above publication, a splint member made of square timber is attached to the upper part of the back surface of the curtain plate to prevent fraud. The splint member protrudes above the upper surface of the curtain plate, and substantially closes the gap between the mating surfaces of the front frame and the curtain plate from the back surface side when the front frame is closed. Thus, when the wire or the like is inserted through the gap, the wire or the like is prevented from being inserted by the splint member.

[0003]

However, in the pachinko machine described in the above publication, as a fraud prevention means,
Since the splint member made of square timber is provided, there is a problem in that a considerable space is occupied by the splint member.

The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to provide a fraud prevention means in an outer frame of a pachinko machine without impairing the fraud prevention function. It is to provide an effective technique for reducing the occupied space.

[0005]

In order to achieve the above object, an outer frame of a pachinko machine according to the present invention is configured as described in claims 1 to 3. The invention according to each of these claims comprises an outer frame body and a curtain plate fixed to the lower front surface of the outer frame body, and the front frame can be opened and closed at a position above the curtain plate on the front surface of the outer frame body. This is a technology that can reduce the occupied space of the fraud prevention means without impairing the fraud prevention function in the outer frame of the attached pachinko machine.

In the outer frame of the pachinko machine according to the first aspect, a flat plate-shaped top cover is mounted on the top surface of the curtain plate, and the top cover is provided with a vertical wall standing upright on the back side of the closed front frame. It is characterized by that. Therefore, even if the player tries to commit an illegal act by inserting a wire or the like through the gap between the mating surfaces of the front frame and the top cover of the curtain plate with the front frame closed, the vertical length set on the top cover is set. The wall can prevent the insertion of wire or the like and prevent fraud. And
In the invention according to claim 1, as a player's cheating prevention means, since a flat vertical wall is provided on a flat top cover covering the top of the curtain, a splint member made of conventional lumber is used as the curtain. The occupying space can be significantly reduced as compared with the structure in which the nail is firmly fixed. Thereby, the lower rear space of the outer frame can be effectively utilized. In addition,
The top cover is formed of, for example, a metal plate such as an iron plate or a stainless plate or a hard resin plate, and protects the curtain plate by avoiding direct contact of the front frame with the upper surface of the curtain plate when the front frame is opened and closed. In this case, as described in claim 2, it is preferable that the vertical wall is integrally formed with the upper surface cover. With such a configuration, the number of parts can be reduced and the manufacturability can be improved.

In the outer frame of the pachinko machine according to claim 3,
The curtain plate is composed of a curtain plate body fixed to the outer frame body and a removable decorative plate that covers the front surface of the curtain plate body, and the top cover is configured to be removable from the curtain plate. In addition, it is characterized in that it is integrally provided with a decorative plate pressing portion for pressing the upper end of the front surface of the decorative plate from the front side. With the above configuration, the decorative plate can be attached and detached with the top cover removed from the curtain plate. Therefore, for example, in a pachinko hall, when replacing the pachinko machine body (usually consisting of the front frame and the game board and various equipment attached to it) to replace the new stand, the pachinko machine body design The decorative plate can be replaced together. Then, in the mounted state of the decorative plate, the upper end front surface portion can be held in a stable state by being pressed from the front surface side by the decorative plate pressing portion of the top cover.

In the pachinko machine constructed as described above, when the front frame 30 is closed, it is fixed to the lower surface of the front frame 30 and the upper surface of the curtain plate 20, that is, the upper surface of the curtain plate body 21 in this embodiment. There is a possibility that a gap will be created in the mating surface with the upper surface cover 23 that has been created, and the player may engage in fraudulent activity by inserting a wire or the like through the gap. Therefore, in the present embodiment, as a means for preventing the above-mentioned misconduct, a vertical wall 23b which is made of a flat plate for preventing insertion of wires or the like and stands up at a predetermined height is formed on the upper surface cover 23.
In the present embodiment, the vertical wall 23b is integrally formed by bending the rear end portion of the top cover 23 upward by approximately 90 degrees. That is, the vertical wall 23b serves as the upper surface cover 2
It is formed in a flat plate shape extending over substantially the entire length in the left-right direction (longitudinal direction) of 3 and is arranged so as to face the back surface of the closed front frame 30 at a slight interval. The plate thickness of the top cover 23 is uniform throughout, and therefore the plate thickness of the vertical wall 23b is also the same as that of the top cover 23. The vertical height of the vertical wall 23b is equal to that of the front frame 30.
In the closed state, it suffices to have a height that exceeds at least the gap generated in the mating surface between the front frame 30 and the top cover 23.

In the present embodiment, as described above, when the front frame 30 is closed, the gap between the mating surface between the lower end of the front frame 30 and the upper surface of the curtain plate 20 is set to the front frame 30.
Since it is configured to be closed by the vertical wall 23b on the back surface side of the player, even if the player attempts to conduct an illegal act by inserting the wire or the like through the gap between the front frame 30 and the curtain plate 20, the insertion of the wire or the like is not performed. By 23b, it is possible to prevent and prevent fraudulent acts. In this case, in the present embodiment, the vertical wall 2
By bending 3b at the rear end portion of the upper surface cover 23, a plate shape having the same plate thickness as the upper surface cover 23 is formed.
The space occupied by the vertical wall 23b is extremely small. That is, according to the present embodiment, it is possible to reduce the occupied space by the fraud prevention means as compared with the conventional case in which the splint member made of square timber is provided as the fraud prevention means. This makes it possible to effectively utilize the lower rear space of the outer frame 10. Also,
Since the vertical wall 23b is provided integrally with the upper surface cover 23, the number of parts can be reduced, and the vertical wall 23b can be easily manufactured by press molding, thus improving productivity.

Then, by installing a new decorative plate, the decorative plate 22 can be replaced with a design that matches the design of the pachinko machine body of the new stand.

In the above description, the upper cover 23 and the side cover 25 are detached from the curtain plate main body 21, and the decorative plate 22 is attached to and detached from the attachment groove 15b. Is. For example, since the decorative plate 22 is formed of a thin plate, by removing the top cover 23, the decorative plate 22 can be slid upward even if the left and right side covers 25 are still attached to the curtain plate body 21. 6 from the mounting groove 15b
As shown by the chain double-dashed line, bend it forward (bend it)
The side cover 25 can also be removed by removing the left and right ends from the flange portion 25a of the side cover 25. As a matter of course, the mounting can be performed by reversing the above procedure. Further, in the present embodiment, the attaching / detaching direction of the decorative plate 22 to / from the mounting groove 15b is the vertical direction. However, for example, when one of the left and right side covers 25 is removed, one end of the decorative plate 22 is attached to the mounting groove 15b. After being fitted from the lateral direction, the decorative plate 22 is installed along the mounting groove 15b.
It is also possible to slide it on and off. When the slide plate is configured to be slidably attached and detached in the lateral direction as described above, the decoration plate 22 has a size capable of completely covering the front surface of the curtain plate body 21 in the mounted state, that is, the mounting groove is larger than that of the curtain plate body 21. 15
It is preferable to form it in a dimension widened by an amount corresponding to the depth of b.

In this case, in this embodiment, the mounting groove 15 is formed in the lower horizontal frame plate 15 which is a constituent member of the outer frame body 11.
b is formed, and the lower end of the decorative plate 22 is fitted into the mounting groove 15b to be mounted. Therefore, the protruding portion 15 of the lower horizontal frame plate 15 that is the lower frame portion of the outer frame body 11
It is only necessary to perform groove processing on the upper surface of a, and there is no need to perform any special processing on the decorative plate 22 and the curtain plate body 21,
This simplifies the mounting structure and is effective in improving productivity.

Further, in the present embodiment, the opening / closing operation of the front frame 30 is facilitated, and the upper end front face of the decorative plate 22 is forwarded to the upper face cover 23 set to protect the upper face of the curtain plate 20. The flange portion 23a for pressing down from is integrally provided. That is, in addition to the original function of the top cover 23, the function of pressing the decorative plate 22 is added, so that the number of parts can be reduced.

It should be noted that the present invention is not limited to the above-described embodiments, but can be modified as appropriate without departing from the scope of the invention. For example, although the outer frame main body 11 and the curtain plate main body 21 are each made of wood in the above-described embodiments, other metals such as aluminum alloy can be used, or a hard resin having high strength can be used. In that case, the hard resin can be used. Further, although the top cover 23 is made of metal in the present embodiment, it may be made of hard synthetic resin. Further, although the vertical wall 23b is formed integrally with the top cover 23, it may be formed separately and then fixed to the top cover 23 to be integrated.
