Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial application field) The present invention relates to a pachinko machine equipped with a light-shielding panel that makes the surface of a game board invisible when hitting or when an illegal act using a magnet or the like is performed. It is about the machine. And
In particular, the present invention relates to a structure in which the light shielding panel is inserted between two glass plates in a glass door frame.

(Prior art) Conventionally, when a hit table has been generated, a tag of "scheduled end" has been attached by an employee of the game arcade, but it is necessary to stick the work every time the hit table is generated. Management is cumbersome. In addition, since the pachinko machine is left as it is after being hit, the situation of the nail of the hitting table is studied by the player.

One of the solutions to this problem is disclosed in Japanese Patent Application Laid-Open No. 1-3313076. In this machine, the front of the pachinko machine is composed of instantaneous dimming glass including a liquid crystal sheet instead of a normal glass plate, and at the time of stopping, the instantaneous dimming glass is made opaque to make the game board invisible and partially It is possible to display that it is a stop table.

(Problems to be Solved by the Invention) However, since this is to use a light control glass instead of a normal glass plate, that is, to use the light control glass in a state of being exposed to the outside, When a player hits or hits a launched pachinko ball,
There is a problem that the risk of breaking is extremely high. In addition, the size of the glass door frame varies depending on the type of pachinko machine, but since the light control glass is used as a substitute for the glass plate, the light control glass is manufactured by changing the size according to the type of pachinko machine Must. For this reason, the light control glass becomes a dedicated component for each pachinko machine, and lacks versatility.

Therefore, an object of the present invention is to provide a pachinko machine incorporating a light-shielding panel which is highly versatile and protected from damage.

(Means for Solving the Problems) In order to achieve the above object, the configuration of the invention according to claim 1 is characterized in that a glass door frame is usually provided between two glass plates arranged at a predetermined gap in front and back. Sometimes a game board can be seen through, and a light-shielding panel that can be changed to an opaque state that cannot see through the game board by an electric signal at the time of hitting etc. is interposed, and the thickness of the light-shielding panel is the gap between the two glass plates The light shielding panel is set to be smaller than the interval, and is incorporated in the glass door frame so as to be freely inserted and removed.

According to a second aspect of the present invention, in the first aspect, a cover plate for opening and closing a gap between the two glass plates is provided above the glass door frame, and the light shielding panel is formed by the cover plate. It is characterized by being held down and held.

In a third aspect of the present invention, in the first or second aspect, a message display area is set in an area of the light-shielding panel corresponding to an area irrelevant to a winning area in the game board. It is characterized by the following.

(Operation) The light-shielding panel is inserted into a pachinko machine by being inserted between two glass plates of a glass door frame. Since the light-shielding panel is in a transparent state during a normal game, the player can see through the board of the game board. However, at the time of hitting or the like, the light-shielding panel becomes opaque and cannot be seen through the game board.

(Example) Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

FIGS. 1 to 3 show a first embodiment of the tree invention. First, a pachinko machine to which the first embodiment is applied will be described mainly with reference to FIG.

A metal frame 3 is attached to the opening of the front frame 2 of the pachinko machine 1. The metal frame 3 has a glass door frame 5 (see FIG. 1) having two glass plates 4 a and 4 b and a front plate 6. Is provided so as to be openable and closable. The glass door frame 5 will be described later in detail. An upper plate 7 for storing the paid-out prize balls and supplying a hitting ball to a firing position is attached to the front plate 6, and a hitting ball is provided on the front surface of the front frame 2 below the upper plate 7. An operation handle 8 for adjusting the force and a lower plate 9 for storing prize balls that could not be stored in the upper plate 7 are attached.

Further, a game board 10 is detachably attached to the back of the front frame 2. On the game board 10, a guide rail 11 for guiding a hit ball and forming a game area is planted. A variable display device 12 is provided substantially at the center of the game area, and the variable display device 12 is provided with a hitting prize hole 13a to 13c arranged on the game board 10 so that a hit ball wins, for example, 3
The digit number starts variable display, and the variable state is stopped after a certain period of time or when the player presses a stop switch (not shown). When the display mode at the time of stoppage is a specific combination (for example, all “7” are displayed), the variable prize winning device 14 is set to the big hit state for a fixed time (for example, 30 seconds) or a predetermined number (for example, 10). The open state is continued until the winning prize ball wins. When the winning prize ball winning the variable winning device 14 wins the V winning opening 15 formed therein, the variable winning device 14 is opened again under the above-described conditions, and such an open state is set to the V winning opening. It is set to last up to 10 times as long as the winning ball wins.

Further, a plurality of winning openings 16a to 16c and a jackpot lamp (no symbol) are provided in the game area, and an out opening 17 for hitting a ball which has not won any winning opening is formed at the bottom.

By the way, as shown in FIG.
Glass storage grooves 18a, 1 for storing one glass plate 4a, 4b
8b is provided. Both glass storage grooves 18a, 18b have a predetermined space 20 between the two grooves by a partition piece 19 bent so as to bulge inward. Thereby, the distance between the glass plate 4a on the front side of the pachinko machine surface and the game board 10 is secured, and the illegal act of guiding a ball on the game board by a magnet or the like from the surface of the glass plate 4a is avoided. . In addition,
The glass storage grooves 18a, 18b and the partition piece 19 are formed on both sides and the lower part except for the upper part, so that the glass plates 4a, 4b can be inserted from above.

On the other hand, the lower end of the upper horizontal frame piece 5a of the glass door frame 5 is folded back to form a retaining piece 21, and a retaining groove 22 is provided between the upper horizontal frame piece 5a and the retaining piece 21. I have. The glass door frame 5 is provided with a cover plate 23 for opening and closing the upper openings of the glass storage grooves 18a and 18b. The cover plate 23 is connected to a support rod 25 fixed to the upper part of the outer surface of the glass storage grooves 18a and 18b, and can open and close around the support rod 25. Connecting piece 26 engaging with 22
Are bent.

Next, the main part of the first embodiment will be described.
A light-shielding panel 27 composed of a liquid crystal element is interposed in 20, and is mounted and supported on the lower partition piece 19.
As described above, the size of the glass door frame 5 is slightly different depending on the model, but if the light shielding panel 27 is manufactured according to the minimum size model, the size of the glass door frame 5 for each model can be reduced. Light fluctuation panel
27, even if it is built into the largest model,
The front surface of the game board 10 can be effectively covered.

Describing the structure of the light-shielding panel 27, the light-shielding panel 27 is composed of a liquid crystal element which is normally used, that is, a liquid crystal cell 28c and two polarizing plates 28a and 28b sandwiching the liquid crystal cell 28c are used. . In the liquid crystal cell 28c, a liquid crystal material is sandwiched between two substrates (glass plate or transparent plastic plate). Although not shown in detail, a transparent electrode (conductive film) is attached to almost all regions on the inner surfaces of both substrates. However, in this embodiment, the character "stopper" is cut out in the center of the electrode, and the character M of "stopper" is displayed in a punched shape. Then, the wiring 29 connected to both electrodes is drawn out from a through hole 30 opened in a part of the partition piece 19, and then connected to a management device (control device or the like) of a game arcade via an appropriate drive circuit. The light-shield panel 27 is energized based on an electric signal such as a stop command.

Next, the operation and effect of the first embodiment will be described. Light shielding panel
In the normal state (at the time of a game), no voltage is applied, so that the state 27 is in a transparent state in which the rear game board 10 can be seen through, and does not cause any trouble in the game. However, when a predetermined number of prize balls are paid out, a stop command is issued from the management device. Based on this, since a voltage is applied to the liquid crystal cell 28c, the display area of the light-shielding panel 27 is completely dark except for a part (the character portion M of the "stopper") (see FIG. 3). . For this reason, since almost the entire surface of the game board 10 cannot be seen, it is possible to prevent the situation of the nail of the driving stand from being studied. In this way, the light-shielding panel 27 is darkened, while only the character of “stopper” is raised at the center to indicate that it is a stopper. Therefore, even if the employee does not put the end-of-schedule tag, the stop display is automatically performed based on the instruction from the management device, so that the management becomes easier than before. Further, in this embodiment, since the drive control of the light shielding panel 27 requires only simple ON / OFF, there is an advantage that the control method is extremely simple.

Furthermore, since the light-shielding panel 27 is housed in a state sandwiched by the glass plates 4a and 4b and does not receive a direct impact, even when a player hits or hits a fired pachinko ball, Protected from damage such as cracking.
In addition, if the light shielding panel 27 is lifted to open the space 20 by lifting the cover plate 23, the light shielding panel 27 can be easily inserted from above and can be easily taken out and collected. Both operations of collection become easy. In addition, since the light-shielding panel is installed at a location common to various pachinko machines and can be incorporated into any of the models, it is versatile and can be reused. Furthermore, since it is installed using the existing space between the two glass plates 4a and 4b, there is no need to set up a dedicated space for the light-shielding panel 27, and there is no need to squeeze other spaces in the pachinko machine. Can be applied to existing pachinko machines.

In this example, the light-shielding panel 27 is made opaque by energization.However, if the polarization direction of the polarizing plate is changed, it is possible to make it transparent when energized and opaque when not energized, contrary to this example. It is. Alternatively, a magnetic sensor may be set at an appropriate position on the game board, and when the sensor detects a magnetic force, the light shielding panel 27 may be darkened. By doing so, the winning opening cannot be seen at all, so that fraudulent acts using magnets can be reliably eliminated. In this case, if a separate electrode is provided for the character portion M so that the character portion M can be made completely dark, it can be distinguished from the striking table.

FIG. 4 shows a second embodiment of the present invention.
In the embodiment, the height range from the out opening 17 to the lower part of the variable winning device 14, that is, the minimum necessary area not related to the winning of the hit ball, is set as the message display area in the light shielding panel 27. In this case, electrodes are arranged in a matrix in a message display area of the light shielding panel 27, and various messages are printed in a dot matrix system based on a command from a control device (not shown) provided in each pachinko machine. It can be displayed. The displayed message may be a big hit display such as "big hit" as shown in FIG. 4 if the game is being played, or information about the game (for example, the number of times the big hit is continued) may be displayed together or alone. And the message is not only at the time of the jackpot,
Some kind of message (for example, store promotion / advertisement, etc.) may be always displayed during a normal game. Also,
In the case where the stop is made, a setting is made in this message display area to display the stop (displaying the character of "stop table"), and to make all the areas above it dark.

Note that color display may be performed using a color liquid crystal in a message display area of the light shielding panel 27,
In addition to the dot matrix display, a segment display may be used. Furthermore, the message display area of the light shielding panel 27 may be set on the upper part of the glass door frame 5, or may be set on both sides.

The other configuration is the same as that of the first embodiment, and the operation and effect of making it impossible to see through at the time of hitting are the same as those of the first embodiment.

(Effects of the Invention) The effects of the present invention are as follows.

The light-shielding panel is interposed between the two glass plates of the glass door frame and is stored in a state where the front and rear surfaces are protected by the two glass plates, so that the light-shielding panel is effectively protected from damage. Further, since the light-shielding panel is not assembled as a substitute for a glass plate, but is incorporated between the two glass plates between them, versatility applicable to pachinko machines of different manufacturers is secured, and reuse is possible.
