Description

  The present invention relates to a sealing protection member, an electronic board unit, a game machine, and a board case, and more particularly to a sealing protection member that can contribute to prevention and early detection of fraud against an electronic board sealed in a case.

  In a gaming machine such as a pachinko machine, a ball that has been bulleted flows down a game area (an area formed on or near the game board surface for realizing a game or an effect by the flow of the ball). In the course of the flow, the ball rolls while colliding with an obstacle nail (also called a gauge) or impeller in the game area, and the flow direction changes. As a result, if a ball wins various winning holes arranged on the game area, a predetermined prize ball is paid out. On the other hand, if a ball flows into the out port without winning any prize hole, no prize ball is paid out. . The player enjoys the game by demonstrating his / her skill in the ball or using the chance of the ball flowing down and expecting to win a prize and give away a prize ball.

  In such pachinko machines, game modes and effects have become more complex and diversified year by year, and the structure and functions of electronic boards for controlling the operation and effects of game machines have also become more complex and diversified. ing. If such an electronic board is illegally destroyed or modified, there is a risk that the game will not be performed properly or that some illegal players will be given an unfair advantage. . Therefore, for the electronic board and its surrounding structure, a device that makes it difficult to access from the outside, a device that makes it easy to grasp the trace and history when there is unauthorized access from the outside, etc. Need to be done.

  For example, in Patent Document 1, a mirror surface member is disposed so as to face the back surface of the electronic substrate, and the back surface image of the electronic substrate reflected by the mirror surface member is visually recognized from the front surface side of the electronic substrate, so The structure which can confirm easily is disclosed. Further, for example, in Patent Document 2, it is difficult to cut the seal seal by applying a seal seal so that the joint of two substrate cases sealing the electronic substrate has a zigzag shape (non-linear shape) and straddles the zigzag shape portion. The structure to perform is disclosed.

JP 2005-261696 A JP 2006-87807 A

  However, in the configuration disclosed in Patent Document 1, it is necessary to pull out the electronic board and the board box that accommodates the electronic board so as to rotate toward the front in order to check for improper traces. By providing a gap between the back surface of the electronic board and the mirror surface member, it is necessary to check the fraudulent trace by using the gap to look into the mirror surface member. I had to take the trouble of peeping.

  In the configuration disclosed in Patent Document 2, if the seal seal is carefully cut along the joint between two zigzag-shaped substrate cases, it will be difficult to confirm the trace. For this reason, it has been difficult for this configuration to exhibit sufficient effects for prevention of illegal acts on electronic substrates and early detection thereof.

  The present invention has been made in view of the above circumstances, and while effectively preventing fraudulent acts on electronic boards, it is simple and reliable without taking any trouble when such fraudulent acts are performed. It is an exemplary problem to provide a sealing protection member, an electronic board unit, a gaming machine, and a board case that can confirm a trace and contribute to prevention and early detection of fraud.

  In order to solve the above-described problems, a sealing protection member as an exemplary aspect of the present invention is provided with a plurality of substrate cases to prevent separation at a joint of a plurality of substrate cases that enclose an electronic substrate in cooperation. It is a sealing protection member for protecting the sealing member fixed so as to straddle, and is formed of a translucent material and disposed so as to cover the sealing member, so that it corresponds to the joint of the sealing member It is characterized by having a protection base part which makes a corresponding part visible from the outside through a seal protection member, and a magnifying lens part which is formed of a translucent material and enlarges and presents an image of the corresponding part.

  According to the present invention, since the sealing member is fixed so as to straddle the joints of the plurality of substrate cases and prevents separation of the substrate case, the sealing member is damaged in order to access the electronic substrate from the outside. Alternatively, it is necessary to separate the substrate case by breaking. Therefore, in the case of unauthorized access to the electronic board, the trace of the unauthorized access remains on the sealing member.

  Here, the sealing member is typically a so-called sealing seal, but is not limited to a seal. Any member that can prevent separation at the joint of the substrate case may be used. For example, a metal member, a resin member, and the like can be conceptualized. Further, the material of the seal seal may be paper or a resin film. Further, the “fixing” of the sealing member is a concept including sticking with an adhesive or an adhesive, irreversible engagement or locking with a caulking, hook or the like, and irreversible screwing with a screw or the like.

  Since the sealing protection member is disposed so as to cover the sealing member, it is possible to prevent the sealing member from being accidentally damaged during normal use. For example, since the sealing member is prevented from being unintentionally damaged at the time of attachment work to other members of the substrate case or maintenance such as cleaning of the substrate case, if the sealing member is damaged, the electronic substrate is immediately It can be understood that there was an illegal access act against.

  Since the sealing protection member is formed of a light-transmitting material, the sealing member can be easily visually recognized from the outside through the sealing protection member. The sealing protection member has a magnifying lens portion, and an enlarged image of a corresponding portion corresponding to the joint of the sealing member, that is, a portion where the sealing member is fixed across a plurality of substrate cases can be presented. It can be done. Therefore, even if a fraudulent act is skillfully performed and the degree of breakage of the sealing member is small, the broken portion is greatly enlarged and presented so that the traces of fraud can be more easily recognized. It has become.

  Prevention of unauthorized access to the electronic board and unauthorized access by a sealing member that prevents separation of a plurality of substrate cases and a sealing protection member that is formed of a light-transmitting material and has a magnifying lens unit The early detection is effectively realized. The seal protection member is typically a resin member formed of a light-transmitting resin material such as acrylic or polycarbonate. Of course, the sealing protection member may be provided with a function of preventing the separation of the plurality of substrate cases in the same manner as the sealing member. Specifically, the sealing protection member may be bonded or welded across a plurality of substrate cases, or may be locked so as not to be removed by a locking hook, or may be crimped.

  For example, the magnifying lens portion may be formed in a normal convex lens shape, but may be formed in a Fresnel lens shape. Thereby, it is possible to exhibit a sufficient enlarged display function while forming the seal protection member thin. Of course, the magnifying lens part and the protective base part may be formed separately, or may be integrally formed by integral molding.

  The seal protection member according to another exemplary aspect of the present invention is fixed so as to straddle the plurality of substrate cases so as to prevent the separation at the joint of the plurality of substrate cases including the electronic substrate in cooperation. A sealing protection member for protecting a sealing member, which is formed of a light-transmitting material and disposed so as to cover the sealing member. And a protective base portion that is visible from the outside, and a deflection presentation portion that is formed of a light-transmitting material and that deflects and presents the image of the corresponding portion by refraction or reflection.

  According to the present invention, since the sealing member is fixed so as to straddle the joints of the plurality of substrate cases and prevents separation of the substrate case, the sealing member is damaged in order to access the electronic substrate from the outside. Alternatively, it is necessary to separate the substrate case by breaking. Therefore, in the case of unauthorized access to the electronic board, the trace of the unauthorized access remains on the sealing member.

  Since the sealing protection member is disposed so as to cover the sealing member, it is possible to prevent the sealing member from being accidentally damaged during normal use. For example, since the sealing member is prevented from being unintentionally damaged at the time of attachment work to other members of the substrate case or maintenance such as cleaning of the substrate case, if the sealing member is damaged, the electronic substrate is immediately It can be understood that there was an illegal access act against.

  Since the sealing protection member is formed of a light-transmitting material, the sealing member can be easily visually recognized from the outside through the sealing protection member. The sealing protection member has a deflection presenting portion, and refracts or reflects an image of a corresponding portion corresponding to the joint of the sealing member, that is, a portion where the sealing member is fixed across a plurality of substrate cases. The deflection can be presented. Therefore, for example, even when the corresponding portion is arranged at a position where it is difficult to visually recognize from the front, the corresponding portion can be easily visually recognized from the deflected direction instead of the front.

  Prevention of unauthorized access to an electronic board and unauthorized access by a sealing member that prevents separation of a plurality of substrate cases and a sealing protection member that is formed of a light-transmitting material and has a deflection presenting portion The early detection is effectively realized.

  The deflection presentation unit may be formed in a prism shape, for example. If the refraction function and the reflection function exhibited by the prism are utilized, the image of the corresponding part can be easily deflected and presented. Of course, the deflection presenting portion and the protective base portion may be formed separately, or may be integrally formed by integral molding.

  According to still another exemplary aspect of the present invention, an electronic board unit includes an electronic board, a plurality of board cases, a sealing member, and the above-described sealing protection member.

  Since the electronic board unit has the sealing member and the sealing protection member, unauthorized access to the electronic board sealed in the board case can be surely prevented. It also has an effect of preventing accidental breakage of the sealing member. Furthermore, since the seal protection member presents the corresponding part in an enlarged manner or presents it in a deflected manner, the visibility of the corresponding part is improved, and it is possible to contribute to early detection in the event of unauthorized access.

  A gaming machine as still another exemplary aspect of the present invention includes a gaming apparatus body that realizes a game using a gaming medium, and a frame body that holds the gaming apparatus body so that the player can visually recognize from the front. The electronic board unit is arranged behind the gaming apparatus body in the frame so that the seam faces either the upper side, the lower side, the right side or the left side.

  Since this gaming machine has the electronic board unit described above, it is possible to effectively prevent unauthorized persons from illegally accessing the electronic board of the gaming machine. Furthermore, even if an unauthorized access is made, the trace is easy to find. Therefore, this gaming machine can contribute to a safe and secure game by a general player by eliminating cheating by a cheating person.

  In gaming machines, an electronic board unit is often arranged behind the game board and in the vicinity of the back mechanism board. Such a trace of fraud against the electronic board unit is confirmed by viewing from the back of the game board. In such a case, if the joint is facing backward (rear side), the viewer can see the joint from the front, but the joint is upward, downward, right side or left side. When facing one of them, the viewer cannot see the joint from the front, making it difficult to find a trace of fraud.

  However, since this gaming machine has the electronic board unit according to the present invention, even if the seam is facing upward, downward, right side or left side, the part is enlarged and presented, By being presented with a deflection, it is easy to find a trace of fraudulent behavior with respect to visual recognition from the back side. Therefore, it contributes to early detection of fraud.

  Note that the gaming machines include all gaming machines having gaming apparatus bodies that implement games using gaming media, but typically include pachinko machines, pachinko slot machine machines, slot machines, arcade game machines, and the like. . The game media includes pachinko balls in pachinko machines, medals in pachislot machines and slot machines. In the arcade machine, various other game media such as balls and coins can be considered.

  The game apparatus body is for realizing a game using a game medium. For example, a pachinko machine or an arcade machine is a game board, and a pachinko slot machine or a slot machine is a spinning device (so-called reel). . Further, the upper, lower, right side, or left side refers to the respective directions when the gaming machine is viewed from the front of the player, and the rear refers to the direction from the player toward the gaming machine.

  According to still another exemplary aspect of the present invention, there is provided a substrate case including an electronic substrate having an electronic component mounted on a surface thereof, wherein at least a corresponding position portion corresponding to the electronic component or a leg portion thereof is translucent. Therefore, the electronic component or its leg can be visually recognized through the board case from the outside, and the corresponding position portion is a magnifying lens that enlarges and presents the image of the electronic component or its leg. It is characterized by.

  According to this board case, the electronic component mounted on the electronic board or the leg part thereof is enlarged and presented by the magnifying lens part. Can be easily seen from the outside. That is, since the viewer can visually recognize the enlarged image of the electronic component or the leg, it is possible to easily find a remodeling trace or the like. Therefore, this board case can contribute to the early detection of fraud against the electronic board contained.

  In the present invention, the substrate case may refer to an entire case including an electronic substrate, or may refer to each of a plurality of case members constituting the entire case. For example, a substrate case in the case of a plurality of substrate cases that cooperate to enclose an electronic substrate refers to a case member that constitutes the substrate case as a whole. A case in which a plurality of case members cooperate to form a whole is sometimes referred to as a substrate case, and the substrate case encloses an electronic substrate.

  Further objects and other features of the present invention will become apparent from the preferred embodiments described below with reference to the accompanying drawings.

  According to the present invention, it is possible to easily and surely confirm the trace of such an illegal act while effectively preventing the illegal act on the electronic board, without taking any trouble. It can contribute to the prevention and early detection of actions. In particular, when the joints of a plurality of substrate cases enclosing an electronic substrate are arranged at positions where frontal view is difficult and it is difficult to see the traces of fraud at the joints, the present invention presents the traces in an enlarged or deflected manner. Making it easier to see, which greatly contributes to the prevention and early detection of fraud.

  When both cases 43a and 43b are closed, the slide piece 43d of the lid case 43b is inserted into the opening of the slide groove 43c of the main body case 43a, and the lid case 43b is slid rightward. Thereby, the slide groove 43c of the main body case 43a and the slide piece 43d of the lid case 43b are fitted, and both the cases 43a and 43b are closed. On the other hand, when changing from the closed state to the open state, the lid case 43b is slid to the left with respect to the main body case 43a to release the fitting between the slide groove 43c and the slide piece 43d.

  In the main control board unit U ', a sealing portion 35c is provided on the right side thereof. In the sealing portion 35c, the main body case 43a and the lid case 43b are joined together by a boundary line (joint) 35f, and the sealing sticker 41 is affixed to the boundary line 35f portion. Therefore, the sticking of the seal seal 41 prevents the main body case 43a and the lid case 43b from sliding, and the main case 43a and the lid case 43b are forcibly slid to move the main control board case. When opened, the seal 41 is broken or cut to leave a trace.

  A protective cover 52 is attached so as to cover the seal seal 41. The protective cover 52 includes a protective base portion 52a and a prism portion (deflection presenting portion) 52b. Since the protective base 52a is the same as that described in the first embodiment, the description thereof is omitted. The prism portion 52b exhibits a function of deflecting and presenting an image of a corresponding portion of the seal seal 41. FIG. 7 is an explanatory diagram for explaining the deflection presenting function of the prism portion 52b.

  The prism portion 52b is a transparent resin material portion having a triangular cross section. Due to the difference in refractive index between the external air and the resin, the prism portion 52 b functions as a prism that refracts and / or reflects light, and deflects and presents the image of the corresponding portion of the seal seal 41 toward the rear of the pachinko machine 2. That is, the image of the corresponding portion of the seal seal 41 facing rightward is reflected by the oblique side portion 52c and presented easily to a viewer viewing from behind.

  Therefore, the protective cover 52 according to the second embodiment of the present invention is a seal that is normally difficult to visually recognize from the back when the main control board unit U ′ is attached to the back side of the game board 6. Since the corresponding portion of the seal 41 is deflected and presented so as to be easily visible rearward, the viewer can easily and quickly find a trace of fraud by confirming from the rear.

  In FIG. 7, the prism portion 52b is configured as a substantially right-angled isosceles triangle (that is, the apex angle is about 45 °), and the reflection direction at the oblique side portion 52c is straight rearward. As shown in FIG. 8 (a), the orientation of the prism portion 52b is changed, or as shown in FIG. Various adjustments are possible. In that case, of course, the image light of the corresponding part is refracted not only in the reflection at the oblique side 52c but also in the incidence to each side of the triangle and the emission from each side. By making the hypotenuse part 52c a curved surface, the function of enlarging or reducing the image of the corresponding part is also exhibited.

FIG. 9 is a longitudinal sectional view of a main control board case (board case) 62 according to Embodiment 3 of the present invention. The main control board case 62 is the same as the first and second embodiments in that the main control board 34 is included in cooperation with the main body case 62a and the lid case 62b. In the third embodiment, a part of the lid case 62b is a magnifying lens portion 62c.

  The magnifying lens portion 62c is configured to have translucency, and is disposed at a position corresponding to the ROM 34b and / or the leg portion 34c as an electronic component mounted on the surface of the main control board 34 included. Has been. For example, the entire lid case 62b may be formed of a transparent resin, or only the magnifying lens portion 62c may be transparent.

  The ROM 34b and / or its leg 34c is arranged to be within the focal length of the magnifying lens 62c. As a result, the ROM 34b and / or its A virtual image (enlarged image) of the leg 34c can be enlarged and presented.

  When the main control board case 62 is attached to the back of the game board 6 of the pachinko machine 2, the lid case 62b is attached so as to face rearward. Therefore, a viewer who visually recognizes the main control board case 62 from the rear can view the magnifying lens portion 62c from the front. Due to the function of the magnifying lens portion 62c, the ROM 34b and / or the leg portion 34c on the main control board 34 to be included is greatly enlarged and presented. Therefore, when the ROM 34b is illegally replaced or the ROM 34b is illegally modified, if an improper trace remains in the soldered portion in the vicinity of the ROM 34b or the leg 34c, the trace is enlarged and easily displayed. And the trace can be found quickly.

  As mentioned above, although preferable embodiment of this invention was described, this invention is not limited to these, A various deformation | transformation and change are possible within the range of the summary. For example, the magnifying lens portion in the present invention may be composed of a Fresnel lens. Thereby, compared with the case where it comprises with a convex lens, a protective cover and a substrate case can be formed thinly. In addition, the deflection presenting unit in the present invention is not limited to the one using a prism, and a light guide member such as an optical fiber bundle can also be used. That is, if one end of the optical fiber is opposed to the corresponding portion of the seal seal and the other end is arranged to face the back of the pachinko machine 2, the image of the corresponding portion can be easily seen from the back of the pachinko machine.
