Description

  The present invention relates to an intrusion prevention member and a gaming machine, and in particular, is applied to a so-called seven machine, a ball game machine such as a right object.

  The ball game machine is usually equipped with (1) an outer frame fixed to the installation site of the pachinko hall island facility, and (2) an openable opening on the one side along the left-right direction of the outer frame. An inner frame in which a portion is formed; (3) a game board that is detachably attached to an opening of the middle frame; and (4) a glass door frame (front frame) including a glass plate that covers a front part of the game board. (5) A tray that is attached to a portion of the front portion of the middle frame that is lower than the mounting position of the game board so as to be openable and closable and that has an upper plate portion for storing game balls discharged from the gaming machine And a door member.

  On the front part of the game board, a “rail member comprising an outer rail and an inner rail” is arranged so as to protrude forward, and this rail member is used to form a substantially circular outer edge (outer peripheral wall) of the game area is doing. That is, on the front surface of the game board, (A) an outer rail configured by arranging a band-shaped metal plate with a substantially arc shape (C-shape) with the opening facing downward, and (B) On the inner side of the location where the outer rail is disposed, an inner rail configured by arranging a belt-like metal plate in a substantially arc shape (C-shape) with the opening facing upward is disposed.

  In the front part of the game board, the game ball launched from the lower right side of the game board and raised along the left-up inclined firing rail is located between the outer rail and the inner rail on the left end side of the game board. It is led to the upper left part of the game board through the guide passage. The game ball is surrounded by the entire inner rail and the upper portion of the outer rail through an inlet formed between the upper left end of the inner rail and the upper left end of the outer rail. Released into the gaming area. And in this game area, an out mouth is provided in the lowest part, and various winning devices are arranged in a position above this lowest part.

  When this ball game machine is, for example, a seven machine, a start winning device (start opening) and a big winning device are arranged in the game area. In addition, the ball game machine may determine whether or not to change the gaming state of the gaming machine from the normal gaming state to the big hit gaming state (that is, the special gaming state) (hereinafter referred to as “winning determination”). ) And a symbol display means (for example, constituted by a liquid crystal display device) for performing a fixed display of a determination result symbol indicating the result of the determination.

  This big winning device is usually a portion of a winning opening (which constitutes a specific example of a winning opening and serves as an entrance for a game ball to the big winning device, and is generally called a big winning port. And an opening / closing member for opening and closing the winning opening, and a winning ball detecting means (winning ball detecting switch) for detecting a game ball won through the winning opening. Among these, the opening / closing member is generally configured in a substantially door shape, and is attached to an attachment portion provided on the front portion of the game board. The opening / closing member is tiltable back and forth (rotatable) while providing a tilting fulcrum on the lower end side. This opening / closing member can be appropriately changed in posture between “standing position for closing the winning opening” and “forward tilting posture for opening the winning opening”. The position of the opening / closing member is set to a standing posture when the winning opening condition for winning a prize is not established, and is set to a forward leaning position when the opening condition for winning a prize opening is established.

  Here, the “normal game state” refers to a “game state in which the winning opening allowance condition is continuously not satisfied and the winning opening is kept closed”. In addition, the “big hit game state” refers to a “game state in which the winning opening release condition is intermittently established for a predetermined number of times and the winning opening opening state is realized intermittently”. In the following description, the operation of changing the posture of the opening / closing member from the standing posture to the forward leaning posture and returning it to the standing posture again, that is, the operation of opening / closing the winning opening may be referred to as “unit operation”. .

  In this seven machine, the execution condition of the aforementioned “determination” (that is, the determination execution condition) is determined on the assumption that a “game ball winning in the start winning device (hereinafter referred to as“ start winning prize ”)” is detected. To establish. Further, when the display execution condition of the “symbol indicating the determination result (determination result symbol)” is satisfied, first, the effect display is executed in the symbol display means. This effect display is normally a display (that is, a variable display) whose contents are cyclic display of “a plurality of identification symbols (that is, special symbols)” sequentially. Then, after the effect display is performed for a predetermined fluctuation time, the determination result symbol is fixedly displayed (stopped display) in the symbol display means.

  When this judgment result symbol is a big hit symbol (a symbol indicating that the judgment result is a big hit) (for example, “7,7” or “7,7,7”, etc.), the configuration symbol is displayed in a doublet state In such a case, the gaming state of the gaming machine shifts from the “normal gaming state” to the “hit gaming state (special gaming state)”. Then, when the gaming state of the gaming machine shifts to the “big hit gaming state (special gaming state)”, the opening / closing member is moved a predetermined number of times (so-called “round number”, for example, 14 to 16 times). “Unit operation” is performed.

  That is, when the gaming state of the gaming machine shifts to the “hit gaming state (special gaming state)”, the opening / closing member is opened to change the closed prize-winning device to the opened state. Thereby, it is possible to win a game ball in the winning opening. Thereafter, when a predetermined number of game balls are won in the winning opening or a predetermined time elapses, the opening / closing member is temporarily closed (the opening / closing member is returned to the standing position), and the large winning device is The closed state is established, and “one unit operation” applied to the opening / closing member is completed. That is, the unit operation of changing the posture of the opening / closing member from the closed posture to the open posture and returning to the closed posture is completed. When the “unit operation of the opening / closing member” is repeated a predetermined number of times (so-called “round number”), the gaming state of the gaming machine is returned from the “big hit gaming state” to the “normal gaming state”.

  However, in a gaming machine equipped with an “open / close-type winning device (hereinafter referred to as“ variable winning device ”) such as this big winning device, it may be a target of fraud. That is, a member (hereinafter referred to as “illegal member”) such as a piano wire or a wire from the lower side of the glass door frame in a space portion formed between the game board and the glass door frame arranged in front thereof. ), And the illegal member forcibly opens the variable winning device and illegally causes the variable winning device to win a game ball illegally.

  For example, in the “big prize device”, the tip of an unauthorized member is locked to an opening / closing member (attacker), and the unauthorized member forcibly changes the posture of the opening / closing member (attacker) to a forward tilted posture. Action may be performed. In other words, even though the gaming state of the gaming machine is actually a normal gaming state (even though the allowance condition for opening is not satisfied), the posture of the opening / closing member is forcibly changed to the forward leaning posture. In some cases, an illegal act of illegally trying to obtain a prize ball by illegally entering a game ball (winning) at a prize opening may be performed.

For this reason, various intrusion prevention members have been proposed with the intention of achieving such “prevention of fraud”. For example, (1) a “substantially square” plate-like portion that is in contact with the inner surface of the lower portion of the glass plate facing the game board while being inserted into the glass storage groove of the glass door frame, and the back side of the plate-like portion An intrusion prevention member has been proposed that is formed by a protective wall that is formed in a circular arc shape along the outer peripheral portion of the inner rail and that protrudes from the inner rail (see Patent Document 1). Further, (2) an intrusion prevention member (gap sealing member) that presses against the outer peripheral portion of the game board and the glass door frame and seals a space (gap) formed between the game board and the glass door frame. It has been proposed (see Patent Document 2).
Japanese Patent No. 2530241 JP 2003-205151 A

  However, even if these conventional intrusion prevention members are arranged for the gaming machine, if the skill of the cheating person is high, the cheating action may be executed in a relatively short time. For example, the intrusion prevention member of the conventional example functions effectively against an unauthorized member attempting to enter from below, but cannot function effectively against an unauthorized member attempting to enter from an obliquely lower side. Therefore, by changing the intrusion direction to a direction other than the vertical direction, there is a possibility that the unauthorized member may break through the intrusion prevention member and reach the game area in a relatively short time. .

  Therefore, this type of intrusion prevention member has a structure that makes it more difficult to break through by an unauthorized member, and more reliably prevents the unauthorized act or appropriately prevents the execution of the unauthorized act. It is important to.

A protective wall surface portion is formed using an extended wall body that extends downward, upward, or vertically from a predetermined portion of the main wall body portion and faces the lateral outside of the gaming machine. The sub-wall part,
It is characterized by providing.

  The intrusion prevention member according to claim 1 includes a sub-wall body portion in addition to the main wall body portion, and the sub-wall body portion faces the side outside (right side outside or left side outside) of the gaming machine. It has a protective wall surface (protective wall surface). Therefore, according to claim 1, an intrusion path that extends upward from directly below the intrusion prevention member (in this specification, an intrusion path refers to a "route for an unauthorized member to enter the game area"). It is blocked by the main wall. At the same time, there is a protective wall surface in the middle of the path of a specific intrusion route (that is, an intrusion route where the protective wall surface exists on the path) obliquely below or from the side of the intrusion prevention member. Prevent entry of members.

  In other words, according to the first aspect, the intrusion prevention member is provided with the sub-wall body portion in addition to the main wall body portion, so that not only the intrusion path from directly below the intrusion prevention member but also the intrusion prevention member. An intrusion path (but limited to a specific intrusion path having a protective wall surface on the path) from an obliquely lower side of the intrusion prevention member to the upper side of the intrusion prevention member is also blocked. Therefore, according to the intrusion prevention member of claim 1, it is possible to prevent the intrusion of the unauthorized member from “more directions” than the conventional intrusion prevention member. Therefore, according to the invention of claim 1, it is possible to obtain an intrusion prevention member that can more reliably prevent fraud and can accurately deter execution of fraud.

  Here, as the “rail member” of the invention of each claim, one provided with an outer rail and an inner rail can be exemplified. Among these, the “outer rail” is usually arranged in a substantially arc shape (C shape) with the opening facing downward (in a state of drawing a substantially arc-shaped route on the front surface portion of the game board). And a belt-shaped metal plate). In addition, the “inner rail” is arranged in a substantially arc shape (C shape) with the opening portion facing upward at a portion inside the outer rail in the front portion of the game board. It is configured using a “band-shaped metal plate” arranged in a state of drawing a path of (1). At the front part of the game board, the game ball that is launched from the lower right side of the game board and rises along the left upward inclined launch rail is located between the outer rail and the inner rail on the left end side of the game board. It is led to the upper left part of the game board through the guide passage. The substantially entire inner rail and the upper portion of the outer rail constitute a “region rail portion” having a substantially circular shape (drawing a substantially circular path).

  Of the front portion of the game board, a portion surrounded by the region rail portion is a game region. In this game area, an out port is provided at the lowermost part, and various winning devices are arranged at positions above the lowermost part. In the gaming machine, a launching device is disposed obliquely below and to the right of the game board, and the game ball is launched by the launching device and draws a path that rises from the oblique right side to the left side of the game board below the game board. Ascend along the firing rail. Furthermore, the game ball that has risen along the launch rail is guided to the upper left portion of the game board through a guide path between the outer rail and the inner rail on the left end side of the game board. The game ball is discharged into the game area through an inlet portion (an inlet portion of the game area) formed between the upper left end portion of the inner rail and the upper left end portion of the outer rail.

  The “countermeasures for fraud” of the invention of each claim can be appropriately selected from the “lower half side portion of the region rail portion”, but is configured as “an arc-shaped portion including the lowermost portion of the region rail portion” It is desirable to do. For example, in a Seven machine, among the winning devices arranged in the game area, “a large winning device that can expect a large number of prize balls” is most likely to be a target of fraud. And, this “large winning device” is often arranged above the “lowermost part of the area rail part” (above the out mouth) in the game area. For this reason, it is desirable to select the “counter measure against fraud” in a state including the “part located in the area rail portion immediately below the big winning device (the lowermost part of the area rail part)”.

  The size (path length) of the “counterfeit countermeasure part” is preferably selected in consideration of the width along the left-right direction of the “big prize device”. For example, among the region rail portions, the lowermost portion is arranged in the center, and is an arc-shaped portion (portion that draws an arc-shaped route) that rises on both the left and right sides, and has a central angle of 20 degrees to 180 degrees (particularly , 35 degrees to 180 degrees), it is desirable to configure the “countermeasures for fraud” using a portion having any angle of 35 degrees to 180 degrees.

In Reference Invention 1 and Reference Invention 7 , the arrangement location of the sub-wall body portion (the portion where the extending wall body constituting the sub-wall body portion is extended) can be variously selected, but the left end of the “counter measure against fraud” The part immediately below the right part of the "countermeasure part", the part right below the left part of the "countermeasure part", the part immediately below the right part of the "countermeasure part" Further, the right side portion and the lower surface portion of the main wall body portion (in the case where the main wall body portion has a protrusion on the lower surface portion, it may be the lower end portion of this protrusion). At least one selected location can be the extended location of the sub-wall body. However, in Reference Invention 1 and Reference Invention 7 , an auxiliary extension part is provided in the main wall part (extension part other than the sub wall part), and the auxiliary wall part is extended from this auxiliary extension part. You may let them.

In each reference invention , the specific structure of the main wall portion is not particularly limited. For example, the main wall portion may be constituted by a plate-like wall body whose upper and lower surfaces are directed in the vertical direction, or a wall body having predetermined irregularities. May be. In addition, the “main wall part” of each reference invention has a left-right width (the length when the anti-countermeasure part is projected downward) equal to the left-right direction width of the “anti-countermeasure part” below the “anti-countermeasure part”. A protective wall having a directional width may be disposed, or a protective wall having a lateral width larger than the lateral width of the “tamper countermeasure portion” may be disposed. Furthermore, the width (depth) along the front-rear direction of the “main wall portion” of each reference invention can be selected variously. For example, the distance between the glass door frame and the game board (arrangement site of the main wall portion) For example, a mode in which the front end portion of the main wall body portion is brought into contact with the glass door frame and the rear end portion of the main wall body portion is brought into contact with the game glass door frame.

The intrusion prevention member of the second reference invention disclosed in the present specification for reference (hereinafter referred to as “reference invention 2”) is the intrusion prevention member of reference invention 1 ,
The sub-wall body portion is selected from at least one portion selected from a left end portion of the main wall body portion, a right end portion of the main wall body portion, and a lower end portion of the main wall body portion. It is characterized by drooping.

Reference invention 2 shows a specific example of the intrusion prevention member of reference invention 1 . That is, according to the reference invention 2 , it is possible to more reliably block the intrusion path directed upward from the intrusion prevention member from obliquely below or from the side of the intrusion prevention member, while simplifying the structure of the sub-wall body.

The intrusion prevention member according to claim 2 is the intrusion prevention member according to claim 1 ,
The second subwall body portion as the subwall body portion,
In the gaming machine, a saucer door member having an upper saucer portion for storing game balls is mounted at a position below the glass door frame, and in the gaming machine, a lower dish is located at a position below the saucer door member. The part is provided in a protruding shape,
In the saucer door member, a game ball passage for guiding game balls discharged from the gaming machine into the upper saucer portion passes through the front and rear of the saucer door member, and an outlet portion is located on the left end side in the upper saucer portion. It is provided in a state where it is opened at
The second sub-wall body portion is arranged on a path connecting the lowermost portion of the region rail portion and the entrance portion of the game ball passage in a diagonally up and down direction.

The invention of claim 2 has been made in view of the following viewpoints. That is, in the saucer part (upper part part), since the “game ball passage” opens the exit part toward the front (the direction of the player or the cheating agent), the cheating person There is a possibility that an unauthorized member is inserted behind (behind) the saucer door member through the “game ball passage”. On the other hand, in the invention of claim 2 , when the unauthorized member is inserted behind (behind) the tray door member through the “game ball passage”, the sub-wall body portion is on the intrusion path through which the unauthorized member passes. To place. For this reason, according to the invention of claim 2 , it is possible to prevent illegal acts even more reliably or to more accurately suppress the execution of illegal acts. In addition, as the “route connecting the lowermost portion of the region rail portion and the entrance portion of the game ball passage in an obliquely vertical direction” according to the invention of claim 2 , a “linear route” can be exemplified.

The intrusion prevention member according to claim 4 is the intrusion prevention member according to any one of claims 1 to 3,
In the main wall portion, a transparency lowering process is performed on at least a portion visible from the front of the glass door frame.

  According to the invention of claim 4, fraud can be prevented more reliably, and execution of fraud can be more accurately suppressed. In other words, many of the fraudsters peek into the inside of the gaming machine from the front of the glass door frame when shifting the unauthorized member inserted in the lower position of the gaming board in the gaming machine to the front of the gaming board, Check the position of the unauthorized member (particularly, the position of the tip of the unauthorized member). On the other hand, according to the invention of claim 4, it is difficult to confirm the position of the unauthorized member (particularly, the position of the distal end of the unauthorized member) by performing a process of reducing the transparency of the main wall body portion. Since it is impossible, it is impossible or difficult to execute fraud. Therefore, according to the invention of claim 4, it is possible to obtain an intrusion prevention member that can more reliably prevent fraud and can more accurately suppress the execution of fraud.

  In the invention of claim 4, if the sub-wall body portion is arranged below the portion of the main wall body portion subjected to the transparency reduction process, the fraudulent person can confirm the position of the sub-wall body portion. Difficult or impossible. For this reason, it is even more difficult for a fraudster to perform a fraudulent act.

Here, the “transparency reduction process” of the invention of claim 4 and reference invention 8 described later is a process for reducing the transparency of the main wall body part, that is, the main wall body part can be seen through vertically. This is a process of reducing the degree. Specifically, (1) a process for applying color to the main wall body part, (2) a process for applying a pattern to the main wall body part, (3) a process for applying a figure or other diagram to the main wall body part, 4) A process of providing irregular reflection generating means (scratches, slits, irregularities, etc.) on the main wall (particularly the upper surface), or a combination of two or more of the processes (1) to (4) The process etc. can be illustrated. In the case where the main wall portion is made of an integrally molded product of resin, the color treatment of the main wall portion in (1) may be performed at the time of molding of the integrally molded product (for example, a pigment in the material). Or may be carried out by post-coloring after molding of the integrally molded product. Furthermore, the “perspective reduction process” can be performed by applying the same color, pattern, diagram, etc. to the “cell image” disposed in the game area on the upper surface of the main wall body.

In the invention of claim 4 and related invention 1, as “the part that can be visually recognized from the front of the glass door frame”, “front wall part” of reference invention 3 to reference invention 5 described later, “left side of reference invention 5 ” Examples of the extending portion and the right extending portion ”, a part of these, and the like can be given.

The intrusion prevention member of the third reference invention disclosed in the present specification for reference (hereinafter referred to as “reference invention 3”) is the intrusion prevention member according to any of the inventions of Reference Invention 1 or Reference Invention 2 .
The fraud countermeasure part is arranged in an arc shape that is arranged at the middle of the lowermost part of the area rail part, and becomes higher on the left and right sides,
The main wall portion includes an arc-shaped contact surface portion along the outer peripheral portion of the anti-fraud portion and a rear wall body portion disposed in a state where the corresponding contact surface portion is in contact with the outer peripheral portion;
In a state in which a long plate-like body is used, the longitudinal direction is set to the left and right direction, the rear end portion is integrated with the rear wall body portion, and the front end portion reaches the glass door frame. A front wall body portion to be disposed;
It is characterized by providing.

Reference invention 3 shows a specific mode of the main wall portion. And according to the reference invention 3 , positioning of a fraud countermeasure site | part can be performed smoothly by making the contact surface part of the back wall body part of a main wall body part contact | abut to the outer peripheral part of a fraud countermeasure site | part.

Further, in Reference Invention 3 , the rear wall body part is brought into contact with the outer periphery of the fraud countermeasure part, and the front end part of the front wall body part is made to reach the glass door frame. Increases the degree of contact with the frame. In other words, in order to eliminate or reduce the gap around the intrusion prevention member, it is made more difficult to perform “fraud that causes the unauthorized member to invade from below the intrusion prevention member”.

In Reference Invention 3 , when the rear end portion of the rear wall portion reaches the front surface portion of the game board, “intrusion of unauthorized members” occurs between the rear end portion of the rear wall body portion and the front surface portion of the game board. This is desirable because it is possible to prevent the occurrence of “route” or to narrow the “range in which the intrusion route of illegal members occurs”. In this case, it is particularly desirable that the entire area of the rear end portion of the rear wall body portion reaches the front surface portion of the game board (hereinafter referred to as “the former aspect”), but the rear end portion of the rear wall body portion. Only a part of may reach the front part of the game board (hereinafter referred to as “the latter aspect”).

  Here, the “form of the former” will be specifically described. For example, “the portion excluding the portion located immediately below the out-out portion of the rear end portion of the rear wall portion” is brought into contact with the front portion of the game board. "The portion of the rear end of the rear wall portion located below the lowermost portion of the region rail portion (hereinafter referred to as the" lowermost lower portion ") is referred to as" the position directly below the out port ", or , “A position on the far side of the gaming machine from directly below the out mouth” can be exemplified. Further, in the “latter aspect”, at least the “lowermost lower part” should reach “a position directly below the out mouth” or “a position on the deeper side of the gaming machine than directly below the out mouth”. Is desirable. In this way, it is desirable to make the “lowermost lower part” reach “the position immediately below the out mouth” or “the position on the deeper side of the gaming machine than directly below the out mouth” for the following reason. by.

  That is, the “lowermost part of the area rail part” constitutes a guide part for guiding the game ball (out ball) to the out port provided on the game board surface, but the lowermost part (guide part) of this area rail part The rear end is usually a notch. Moreover, in a game board (game area), a prize winning device is generally arranged at a position directly above the notch, so that the fraudulent person is There is a high possibility of selecting the “route leading to the winning device through the notch” as the “intrusion route of the unauthorized member”. For this reason, it is possible to block this route by causing the “lowermost lower part” to reach “a position immediately below the out mouth” or “a position on the deeper side of the gaming machine than directly below the out mouth”. This is desirable.

  “To make the front end portion of the front wall portion reach the glass door frame” means that the front end portion of the front wall portion is the back surface portion (rear surface portion of the glass door frame, facing the game board). ), The front end of the front wall body part is made to reach the front of the gaming machine rather than the back part of the glass door frame (for example, a recess opening rearward to the back part of the glass door frame) And the front end portion of the front wall portion is made to enter the concave portion. In addition, “to make the front end portion of the front wall portion reach the glass door frame” allows the entire area of the front end portion of the front wall portion (range of the full width along the left-right direction) to reach the glass door frame. In addition to this, part of the front end portion of the front wall portion (part of the range along the left-right direction) reaches the glass door frame. However, in the aspect in which the latter “part of the front end portion of the front wall body portion” reaches the glass door frame, at least “the portion of the front wall body portion located in front of the fraud countermeasure portion” is made of glass. It is desirable to reach the door frame.

Usually, the glass door frame includes a glass plate and a door frame main body that holds the glass plate. However, in Reference Invention 3 , even if the front end of the front wall body portion reaches the door frame main body. It may reach the glass plate, or may reach both the door frame main body and the glass plate. In the invention of each claim, the holding means for holding the glass plate on the door frame main body is fixedly attached to the door frame main body (even if it is attached in a state where it cannot be opened and closed). It may be mounted in an openable / closable state.

In Reference Invention 3 , the entire area of the rear end portion of the front wall portion (the range of the entire width along the left-right direction) may be integrated with the rear wall portion, or the rear end portion of the front wall portion.

In particular, the present embodiment is significant in that the intrusion path using the game ball passage 5B can be blocked by the second sub-wall body portion 530. In addition, since the intrusion prevention member 500 includes the long plate-like body 20L, it is possible to appropriately deal with an illegal act on the variable winning devices (the left winning port 19 and the right winning port 20) other than the big winning device 31.

(3) Effects of the embodiment

  The intrusion prevention member 500 according to the present embodiment includes sub-wall bodies 520 and 530 in addition to the main wall body 510, and the sub-wall bodies 520 and 530 are protected against the lateral outside of the gaming machine 1. Wall surface parts 521, 522, 531a, 531b are provided. Therefore, according to the present embodiment, the main wall body portion 510 blocks the intrusion path that extends from directly below the intrusion prevention member 500. At the same time, a protective wall surface portion exists in the middle of a specific intrusion path obliquely downward or laterally upward of the intrusion prevention member 500, and prevents the intrusion of unauthorized members.

  In other words, according to the present embodiment, the intrusion prevention member 500 includes the sub wall body portions 520 and 530 in addition to the main wall body portion 510, so that only the intrusion path directed from directly below the intrusion prevention member 500 to the upper side. In addition, the intrusion path from the obliquely lower side of the intrusion prevention member to the upper side of the intrusion prevention member 500 is also blocked. Therefore, according to the intrusion prevention member 500 of the present embodiment, it is possible to prevent intrusion of unauthorized members from “more directions” than the conventional intrusion prevention member. Therefore, according to the present embodiment, it is possible to obtain an intrusion prevention member 500 that can more reliably prevent fraud and can accurately prevent execution of fraud.

  Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and is not limited to the wording of each claim without departing from the scope described in each claim. Can be easily replaced by these, and improvements based on knowledge that a person skilled in the art normally has can be added as appropriate. That is, the modification which has the characteristics of several Example can also be illustrated.

  For example, it is also effective to apply a plurality of intrusion prevention members 500 having different extension positions and sizes of the sub-wall bodies 520 and 530 to a plurality of gaming machines arranged in a pachinko hall or island facility. In other words, it is also effective for persons involved in the pachinko hall to wear the intrusion prevention members 500 having different extension positions and sizes of the sub-wall parts 520 and 530 in the adjacent gaming machines. In this case, since any of the intrusion prevention members 500 is subjected to the “permeability reduction processing (coloring)” on the wall body 510, the cheating person can place the second in any part of the main wall body 510. It cannot be determined whether or not the sub-wall body portion 530 is extended. For this reason, the gaming machine to which the individual intrusion prevention member 500 is attached is “a risk that a fraudulent person suffers from executing a fraud (risk of failing fraud, risk of finding a fraud etc.)” It becomes a high game machine. Therefore, these intrusion prevention members 500 can accurately suppress fraud.

  Further, in the intrusion prevention member 500 of the present embodiment, the sub-wall body portions 520 and 530 are integrally and fixedly provided with respect to the main wall body portion 510, but the sub-wall body portions 520 and 530 are provided as the main walls. The wall body 510 may be detachable. In this case, according to the situation of the gaming machine 1, the number and size of the sub-wall body parts 520 and 530 to be used are selected, or the mounting locations of the sub-wall body parts 520 and 530 ( For example, by selecting a portion where the body parts 520 and 530 are to be attached, it is possible to prevent fraud even more accurately. For example, depending on the size of the upper plate 52, the position of the game ball passage 5B (particularly, the position of the entrance of the game ball passage 5B), etc., the number of sub-wall bodies 520 and 530 used and the sub-wall bodies used. This is because fraud can be prevented even more accurately by selecting the size of 520, 530, the mounting location of the sub-wall parts 520, 530, and the like.

  Furthermore, even if all the sub-wall bodies 520 and 530 or a part of the sub-wall bodies 520 (530) constituting the intrusion prevention member 500 are slidably mounted on the main wall body 510. Good. For example, the predetermined sub-wall body portion is slidably engaged with a slide engagement portion (slide rail or slide groove) of the main wall body portion 510 or the like. Then, the “predetermined subwall body portion” is slid with respect to the slide engaging portion, and the extension position of the subwall body portion 520 (530) (in the main wall body portion 510, the subwall body portions 520 and 530 are provided). It is also possible to change the location where the is extended. In this case as well, fraudulent acts can be prevented more accurately by changing the extension position of the “predetermined sub-wall part” according to the situation of the gaming machine.
