Description

  The present invention relates to a gaming machine, and more particularly to an electrostatic noise prevention structure for an image display panel of a gaming machine.

  In recent years, gaming machines that display a lottery pattern or the like on a liquid crystal screen to a player have become common. In this type of gaming machine, a liquid crystal panel is arranged near the front center of the game area as viewed from the player, and a lottery pattern such as animation is displayed on the liquid crystal screen.

  A commercially available general-purpose product is often used for the liquid crystal panel. As a general configuration, a conductive shield member such as a metal plate is provided on the back surface of the panel body. The driver board for controlling the liquid crystal incorporated in the panel body is protected from external electromagnetic waves by this shield member.

A liquid crystal control board box is attached to the back of the liquid crystal panel. The liquid crystal control board box is formed by housing a liquid crystal control board for controlling liquid crystal display in a box body made of synthetic resin. Usually, the box body and the liquid crystal control board are integrally fixed to the back surface of the liquid crystal panel.
The liquid crystal control board is provided with a ground part, and the liquid crystal control board is prevented from malfunctioning by discharging static electricity to the ground of the gaming machine through the ground part (see Patent Document 1).

JP 2003-126492 A

By the way, recently, with the improvement of gaming machines, the size of the liquid crystal panel tends to increase vertically or horizontally from the vicinity of the center of the gaming area. When the liquid crystal panel is enlarged in this way, the driver board of the liquid crystal panel, which has been difficult to be affected by the conventional technique, may approach the other components of the gaming machine and receive electrostatic noise. For example, when a liquid crystal panel approaches a path of a game ball (ball guide rod) that is likely to generate static electricity, problems such as color unevenness of the liquid crystal display and missing dots occur due to the influence of static electricity.
Similarly, when the position of the liquid crystal panel is moved up and down or left and right in accordance with the change of effects such as an accessory, the above-described problems of liquid crystal display can occur.

On the other hand, the structure which avoids the electrostatic noise to a liquid crystal panel using the ground part of the liquid crystal control board mentioned above can be considered. That is, the ground portion of the liquid crystal control board and the shield member of the liquid crystal panel are electrically connected, and static electricity generated in the shield member is released to the ground of the gaming machine through the ground portion.
According to such a configuration, even if the shield member is charged, the charges are quickly removed through the ground portion of the liquid crystal control board, so that the above-described problems of the liquid crystal display can be avoided.

However, as described above, since the liquid crystal control board is housed in the box body, securing the wiring between the liquid crystal control board (ground portion) and the shield member becomes a problem. For example, in a configuration in which the lead wire is taken out from the inside of the box body and the liquid crystal control board (ground part) is connected to the shield member, the lead wire becomes an obstacle when the liquid crystal control board box is attached to or detached from the liquid crystal panel. The work may be hindered.
In addition, a configuration in which a connector connecting port is provided in the box body and the liquid crystal control board (ground portion) and the shield member are directly connected by a dedicated connector is also conceivable, but in such a configuration, the liquid crystal panel and the liquid crystal control board box are Since the relative positional relationship is determined by the position of the connector, it becomes difficult to cope with a change in the mounting position of the liquid crystal control board box accompanying a change in the model of the gaming machine or the like. In particular, the vicinity of the upper end of the liquid crystal panel is a part that easily interferes with the ball guide rod, etc., so the mounting position of the liquid crystal control board box can be adjusted as necessary so that sufficient space is provided on the back of the liquid crystal panel. It is desirable to adopt a structure that can be changed.

  The present invention has been made in view of such a situation, and causes static electricity generated in a shield member of an image display panel such as a liquid crystal panel to escape to a ground portion provided on an image display control board such as a liquid crystal control board. In addition, it is possible to provide a gaming machine in which an image display control board box such as a liquid crystal control board box can be easily attached to and detached from the image display panel and can easily cope with a change in the mounting position of the liquid crystal control board box. It is aimed.

In order to solve the above problems, the gaming machine of the present invention is:
In a gaming machine comprising an image display panel and an image display control board box for controlling the image display of the image display panel,
The image display panel has a conductive shield member on the back of the panel body,
The image display control board box has a box body attached to the back side of the shield member, and an image display control board housed in the box body,
One end of the image display control board box is electrically connected to the ground portion of the image display control board, and the other end is taken out from a small hole of the box body and contacts the back surface of the shield member of the image display panel. There is a conductive member,
When the other end of the conducting member is fixed together with the image display control board box on the back of the image display panel, the conducting member is in contact with the shield member to conduct electricity ,
Before Symbol Dentsu member,
A flat plate portion detachably attached to the image display control board and electrically connected to the ground portion;
An arcuate part that penetrates the wall surface of the substrate box from the flat plate part into an arcuate shape and contacts the shield member;
It is an electrically conductive spring plate material which is formed at the tip of the arcuate portion and which includes a return portion slidably contacting the outer wall surface of the substrate box.

According to such a configuration, static electricity of the shield member of the image display panel is released to the ground portion of the image display control board via the conductive member. Thereby, even if the image display panel is installed in a place where static electricity is likely to be generated in the gaming machine, problems such as color unevenness of the liquid crystal display and missing dots can be avoided.
In addition, since the conductive member is in contact with the shield member on the outside of the box body to form a static elimination passage, the mounting position and orientation of the image display control board box to the image display panel can be achieved simply by shifting the contact position. Can be freely changed. As a result, it is possible to immediately cope with a change in the mounting position of the image display control board box on the image display panel.
Further, the ground lead wire is not taken out from the box body, and the image display control board box can be easily attached to and detached from the image display panel.

In Patent Document 1, a shield member is attached to the board box of the main control board, and the shield member and the ground portion of the main control board are connected to a conductive member (attachment members 202 and 204 of Patent Document 1, FIGS. 5 and 5). 7) is disclosed. In such a configuration, it is necessary to attach a dedicated shield member to the substrate box in advance.
On the other hand, in the configuration of the present invention, the shield member of the image display panel is also used as it is as the shield member of the image display control board. For this reason, a separate dedicated shield is provided for the image display control board of the image display control board box. There is no need to attach a member, and there is an advantage that the manufacturing cost can be reduced by reducing the number of parts.

  The image display panel only needs to have a shield member, and a thin panel such as a plasma panel or a surface electric field panel can be adopted in addition to a liquid crystal panel.

According to such a configuration, the flat plate portion of the conductive spring plate material is electrically connected to the ground portion of the image display control board, and the arcuate portion (bow-shaped convex surface) is electrically connected to the shield member. It escapes to the ground portion of the image display control board via the plate material.
In addition, since the return part can be slid to the outer wall surface of the image display control board box while pressing the arcuate part (arched convex surface) of the conductive spring plate against the shield member, the arcuate part can be easily elastically deformed. The contact state between the conductive spring plate material and the shield member can be kept extremely good. In addition, the attachment and removal of the conductive spring plate material is easy, and the recycling of the conductive spring plate material and the substrate box is facilitated.

This onset Ming can be applied to various gaming machines having an image display panel. For example, a pachinko machine, arrange ball machine, Suzumedama gaming machine, is effectively applied to a game machine such as a slot Tomah thin.
This onset Ming may be applied alone if necessary, may be combined with other inventions described herein.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the present embodiment, the present invention is applied to a pachinko gaming machine.

[Configuration of LCD panel]
6 and 7 are exploded perspective views of the liquid crystal panel 20 and the liquid crystal control board box 30 assembled.
As for the liquid crystal panel 20, the shield board 52 is attached to the back surface of the panel main body 51 (refer FIG. 6). The shield plate 52 is made of a conductive metal such as iron and has a function of shielding and protecting the liquid crystal display unit from external electromagnetic waves.

The driver substrate 53 is covered with a strip-shaped shield film 54 and is shielded from external electromagnetic waves in the same manner as the liquid crystal display unit, thereby preventing malfunction.
The shield film 54 is made of a conductive material such as aluminum foil, and is in contact with the upper end portion of the shield plate 52 to maintain an electrically conductive state. That is, the shield plate 52 and the shield film 54 are in contact with each other, thereby protecting the panel body 51 as a shield member from external electromagnetic waves.

The liquid crystal display unit of the panel body 51 has a conventionally known structure including a liquid crystal layer, a polarizing plate, a backlight, and the like, and displays a lottery symbol to a player by color display with a predetermined resolution.
As the liquid crystal panel 20, a general-purpose product used for a personal computer monitor or the like can be used. For example, a liquid crystal panel of a ready-made size such as 12 inches or 15 inches can be used.

[Configuration of LCD control board box]
In the liquid crystal control board box 30, the liquid crystal control board 62 is housed in a transparent resin box body (see FIGS. 8 to 10). The box body is divided into a case 30A and a case cover 30B, and a mounting portion for the liquid crystal control board 62 is formed inside the case 30A. The liquid crystal control board 62 is fixed to the mounting portion, and the case 30A is covered with the case cover 30B and locked. By doing so, the liquid crystal control board 62 is accommodated in the liquid crystal control board box 30.

  Boss portions 63 are provided at the four corners of the liquid crystal control board box 30 (see FIG. 7). These boss portions 63 are formed at positions corresponding to the screw holes at the four corners of the liquid crystal panel 20, and the boss portions 63 are fixed to these screw holes with screws.

  Electronic components (not shown) such as a CPU, VDP, ROM, and RAM are attached to the liquid crystal control board 62. A circuit pattern having a multilayer structure is formed inside the liquid crystal control board 62, and these electronic components are connected to a predetermined pattern. The surface of the liquid crystal control substrate 62 is covered with an insulating film for preventing exposure of the circuit pattern.

A part of the pattern layer of the liquid crystal control substrate 62 is used as a ground pattern (ground portion). The ground pattern (ground portion) is a reference potential for electronic components and the like on the board, is connected to the ground of the gaming machine 10 via a power source, and is usually a potential of 0 volts.
The ground pattern (ground portion) is also provided on control boards such as the main control board 41a, the sub-control board 42a, the payout control board 34a, the launch control board 37a, and the ground pattern of these boards and the liquid crystal control board. 62 ground patterns are connected by earth wiring. That is, the electric charge of the ground pattern (ground part) of the liquid crystal control board 62 is released to the ground of the gaming machine 10 via the ground pattern (ground part) of another control board.

  As shown in FIG. 10, near the center of the liquid crystal control substrate 62, two through holes H1 and H1 are provided, and a terminal of a ground pattern (ground part) is provided at the edge of these through holes H1 and H1. Ground terminals G, G) are provided. These ground terminals G and G are formed of solder paste or the like, are in contact with the ground pattern (ground portion) at the inner wall portions of the through holes H1 and H1, and are exposed on the substrate surface along the wall surfaces. . The conductive spring plate material 65 described later comes into contact with the exposed portions of the ground terminals G and G on the substrate.

A plurality of pores K are provided on the wall surface of the liquid crystal control board box 30 (see FIGS. 6 to 9). These pores K serve to increase the air permeability in the liquid crystal control board box 30.
A blower fan 66 (see FIG. 6) is attached near the center of the case cover 30B of the liquid crystal control board box 30. The blower fan 66 sends air through the pores K of the liquid crystal control board box 30, and the liquid crystal control board. 62 electronic components and the like are cooled.

[Configuration of Dentsu spring plate material]
Next, the configuration of the conductive spring plate material 65 will be described.
Two conductive spring plate members 65 are attached near the center of the liquid crystal control board box 30 (see FIGS. 7 and 10). The conductive spring plate 65 is made of a conductive metal plate such as copper or iron. One end of the conductive spring plate 65 contacts the ground terminal G of the liquid crystal control board 62 in the liquid crystal control board box 30 and the other end of the liquid crystal control board box. It is taken out of 30 and is in contact with the shield plate 52 of the liquid crystal panel 20 (see FIG. 11).

As shown in FIGS. 12 and 13, the conductive spring plate member 65 is formed by bending a rectangular strip into an arcuate shape. The flat plate portion 65a continues to the arcuate portion 65b, and the return portion 65c continues to the tip. By bending the arcuate convex surface M of the arcuate portion 65b, the electrically conductive spring plate material 65 expands and contracts in the length direction.
A circular through hole H2 is provided in the center of the flat plate portion 65a. The through hole H2 has a hole diameter that can be fitted to a locking pin 71a provided on a base 71 of the liquid crystal control board box 30 described later.

[Connection between Dentsu spring plate and ground]
As shown in FIG. 11, a columnar pedestal 71 extending vertically from the bottom wall is integrally formed in the case 30 </ b> A of the liquid crystal control board box 30. A locking pin 71 a extends at the tip of the pedestal 71. One end (flat plate portion 65 a) of the conductive spring plate material 65 is supported by the base 71 of the liquid crystal control board box 30.
When connecting the ground portion of the liquid crystal control board 62 to the conductive spring plate 65, the flat plate portion 65a of the conductive spring plate 65 is placed on the pedestal 71, and at the same time, the through hole H2 of the flat plate portion 65a is passed through the locking pin 71a. (See FIG. 14). Then, the liquid crystal control board 62 is set on the pedestal 71 and screwed into the through hole H1 through the locking pin 71a. By doing so, one end (flat plate portion 65 a) of the conductive spring plate 65 is sandwiched and fixed between the liquid crystal control board 62 and the base 71, and the ground terminal G at the peripheral edge of the through hole H 1 is attached to the conductive spring plate 65. Contact. That is, one end (the flat plate portion 65 a) of the conductive spring plate material 65 is electrically connected to the ground portion via the ground terminal G.

Here, as shown in FIG. 15, the ground terminal G has radial ridges 73 that are continuous in the outer diameter direction with a uniform length around the through-hole H <b> 1. When the flat plate portion 65a of the conductive spring plate 65 is sandwiched between the liquid crystal control board 62 and the base 71, the plate surface of the flat plate portion 65a is pressed against these radial protrusions 73 by line contact. The surface becomes difficult to shift, and the reliability of electrical connection between the ground terminal G and the conductive spring plate member 65 can be improved.
Moreover, since the radial ridge 73 is pressed against the conductive spring plate 65 by the radial contact surface, the conductive spring plate 65 is less likely to be displaced in the front-rear, left-right, and diagonal directions. As a result, it is possible to prevent the conductive spring plate member 65 from being attached to the back and the backlash, and to stabilize the attached state.

[Connection between Dentsu spring plate and shield member]
The arcuate portion 65b of the conductive spring plate member 65 extends to the outside of the liquid crystal control board box 30 through the slit S of the case 30A (see FIG. 11). The return portion 65 c of the conductive spring plate material 65 is an open end and is in contact with the outer wall surface of the liquid crystal control board box 30.
As shown in FIG. 16A, before the liquid crystal control board box 30 is attached to the liquid crystal panel 20, since the load is not applied to the conductive spring plate material 65, the arcuate convex surface of the arcuate portion 65b remains as it is when it is molded. Swells downward greatly.
From such a state, when the liquid crystal control board box 30 is overlaid on the liquid crystal panel 20 and the boss portion of the liquid crystal control board box 30 is fixed to the screw hole of the liquid crystal panel 20, as shown in FIG. The arcuate portion 65 b of the plate member 65 is pressed and elastically deformed by the shield plate 52 of the liquid crystal panel 20, and at the same time, the return portion 65 c is displaced outward while being in sliding contact with the outer wall surface of the liquid crystal control board box 30. In this way, the conductive spring plate member 65 is brought into surface contact with the shield plate 52 while being elastically deformed, whereby the conductive spring plate member 65 and the shield plate 52 are electrically connected.

FIG. 17 shows an enlarged cross-sectional view of the slit S. Guide slopes 30 h and 30 h are formed at the opening edge of the slit S in accordance with the insertion angle of the arcuate portion 65 b of the conductive spring plate 65. These guide slopes 30 h and 30 h have an inclination of about 45 ° with respect to the wall surface of the liquid crystal control board box 30.
When the conductive spring plate material 65 is pressed against the shield plate 52, the plate surface of the arched portion 65b is brought into sliding contact with either or both of the upper and lower guide inclined surfaces 30h, 30h according to the bending of the arched portion 65b.

  The broken line in FIG. 11 depicts the outline of the conductive spring plate member 65 when the guide slopes 30h, 30h do not exist as a comparative example. In this case, since the slit S opens almost perpendicularly to the wall surface of the liquid crystal control board box 30, the arcuate portion 65 b of the conductive spring plate 65 extends almost directly below the opening of the slit S and hits the shield plate 52. Bend along the plate surface. For this reason, an excessive load is applied to the arcuate portion 65b of the conductive spring plate member 65, and this portion may be crushed and cannot be restored (plastic deformation).

  On the other hand, in this embodiment, guide slopes 30h and 30h are provided at the opening edge of the slit S, and the conductive spring plate 65 is passed through the slit S in an inclined state. Thus, when the conductive spring plate material 65 is pressed against the shield plate 52, the elastic deformation thereof becomes smooth, and an excessive load is hardly applied to the arcuate portion 65b. As a result, the arcuate convex surface of the arcuate portion 65b is prevented from being crushed and deformed.

[Attachment of Dentsu spring plate]
When the conductive spring plate 65 is attached to the liquid crystal control board box 30, the flat plate portion 65a of the conductive spring plate 65 is passed through the slit S from the lower side in FIG. Then, the through hole H2 is hooked on the locking pin 71a. Then, the arcuate portion 65b of the conductive spring plate 65 is pressed against and supported by the guide slope 30h of the slit S.
As described above, in the configuration of the present embodiment, the conductive spring plate member 65 is supported from the case 30A by supporting the flat plate portion 65a and the arcuate portion 65b of the conductive spring plate member 65 at the two locations of the locking pin 71a and the guide slope 30h, respectively. Will not fall. That is, the conductive spring plate material 65 can be easily temporarily attached to the case 30A without using screws or the like.
As a result, the assembly work at the time of manufacturing the liquid crystal control board box 30 becomes extremely easy, which helps to reduce the manufacturing cost. Further, the separation work between the case 30A and the conductive spring plate member 65 is simplified, which is convenient for recycling at the time of disposal.

[Charging action of liquid crystal panel]
In the present embodiment, since the liquid crystal panel 20 having a relatively large size is disposed near the center of the game board 15, the upper end of the liquid crystal panel 20 is positioned close to the tank rail 32 (see FIGS. 2 and 3). The area around the tank rail 32 is a place where game balls collide with each other during the game and are easily charged, and the upper part of the liquid crystal panel 20 is in an environment susceptible to such electrostatic noise.

However, in the gaming machine 10 of the present embodiment, even if static electricity is generated near the upper end of the liquid crystal panel 20, it is immediately released from the shield plate 52 to the ground portion of the liquid crystal control board 62 via the conductive spring plate material 65. As a result, the driver substrate 53 of the liquid crystal panel 20 and the like are not affected by static electricity, so that the malfunction is prevented and the liquid crystal screen does not suffer from problems such as color unevenness and missing dots.
Not only the tank rail 32 but also other peripheral components such as the dispensing device 33 generate static electricity from the shield plate 52 via the conductive spring plate material 65 to the ground portion of the liquid crystal control board 62 in the same manner. Static electricity noise of the liquid crystal panel 20 can be prevented.

[Mounting range of LCD control board box on LCD panel]
As described above, in the gaming machine 10 of the present embodiment, the conductive spring plate material 65 is brought into contact with the shield plate 52 of the liquid crystal panel 20 to form a static elimination passage. Therefore, the liquid crystal control board box 30 can be attached to a relatively wide range on the back surface of the liquid crystal panel 20 within the contact range between the shield plate 52 and the conductive spring plate material 65. That is, in this embodiment, it is not necessary to fix the contact point between the conductive spring plate member 65 and the shield plate 52 in one place, and the mounting position of the liquid crystal control board box 30 can be set as necessary as long as both are in contact with each other. It is possible to slip.

As shown in FIG. 18, the positional relationship between the liquid crystal panel 20 and the liquid crystal control board box 30 in the present embodiment is close to the position immediately below the upper end of the back surface of the liquid crystal panel 20, and the liquid crystal control board box 30 is attached. . In such a positional relationship, while using the same liquid crystal panel 20 and the liquid crystal control board box 30 in the design of different models, the liquid crystal panel is moved upwards of the game area P due to the design of the entire board and the space for arranging other accessories. When it is necessary to move the mounting position of the game machine 20, the liquid crystal control board box 30 may hit the tank rail 32 on the back surface of the gaming machine 10 and be in the way.
In such a case, as shown in FIG. 19, the liquid crystal control board box 30 is displaced downward by a distance L1 and attached to the liquid crystal panel 20, thereby avoiding the liquid crystal control board box 30 from hitting the tank rail 32. The liquid crystal panel 20 can be moved above the game area P.
When the size of the liquid crystal panel 20 is increased, the tank rail 32 can also be used by changing the mounting position of the liquid crystal control board box 30 of the liquid crystal panel 20 when the tank rail 32 interferes with the liquid crystal control board box 30.
At this time, since the conductive spring plate 65 is in contact with the shield plate 52 while being bent slightly from the position shown in FIG. 18, the static elimination passage is not cut off.

  As described above, in this embodiment, the mounting position of the liquid crystal control board box 30 can be freely selected within a range in which the conductive spring plate material 65 contacts the shield plate 52 of the liquid crystal panel 20, thereby easily supporting model changes and design changes. can do.

[Configuration example of liquid crystal control board box moving means]
As described above, the gaming machine 10 of the present embodiment can attach the liquid crystal control board box 30 to a relatively wide range on the back surface of the liquid crystal panel 20.
In order to make effective use of such structural merit, liquid crystal control board box moving means for switching the mounting position of the liquid crystal control board box 30 with a simple operation without complicated work may be employed.

As an example of the configuration of the liquid crystal control board box moving means, a configuration in which a dedicated screw hole for switching the mounting position of the liquid crystal control board box 30 from the state of FIG.
For example, in the state of FIG. 18, the liquid crystal panel 20 is provided with screw holes at the positions of the screws a <b> 1 to a <b> 4 of the liquid crystal control board box 30. In addition to these screw holes, if the screw holes are provided in the positions of screws b1 to b4 of the liquid crystal control board box 30 shown in FIG. 19, the liquid crystal control board box 30 is shifted downward from the upper end of the liquid crystal panel 20 by L1. Can be installed.

Moreover, as shown in FIG. 20, you may provide a screw hole in the screw | threads c1-c4 position of a liquid crystal panel. In this case, the liquid crystal control board box 30 can be mounted upside down on the liquid crystal panel 20, and the liquid crystal control board box 30 can be shifted downward by L2 from the state of FIG.
In addition, it goes without saying that a dedicated screw hole may be provided in the liquid crystal panel 20 so that the states of FIGS.
