Description

  The present invention relates to an electronic board unit and a gaming machine, and more particularly, to an electronic board unit that can contribute to prevention and early detection of fraud against an electronic board contained in a board 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, Patent Document 1 describes a gaming machine that includes a substrate case that includes an electronic substrate in a plurality of substrate cases, and a sticker is pasted so as to straddle the boundaries of the plurality of substrate cases. This seal has an IC chip that stores identification information and an antenna that transmits the identification information to the reader. In this gaming machine, when the seal is peeled off to separate the board case, the antenna is destroyed, and information cannot be read by the reader. Therefore, it is possible to grasp a history when there is an unauthorized access from the outside.

  Further, for example, Patent Document 2 discloses a gaming machine in which a tape-type inlet incorporating an IC chip and an antenna is attached so as to straddle the boundary between two substrate cases, and a seal seal is attached to each end thereof. Are listed. The tape-type inlet and the seal sticker are different in the sticking components, and are configured such that even if the sticking force of the tape-type inlet is invalidated by one chemical, the seal sticker cannot be peeled off. Therefore, as a result, it is possible to obtain an effect that the substrate case cannot be opened without cutting the tape-type inlet. In addition, when the tape-type inlet is cut, the information built in the IC chip cannot be read, and the history of unauthorized access from the outside can be grasped.

JP 2006-305037 A JP 2008-36228 A

  However, in the gaming machine described in Patent Document 1, when the antenna is destroyed due to the seal being peeled off, the information stored in the IC chip cannot be read, but even if the seal is removed, the antenna is destroyed. If not, the information stored in the IC chip can be read, and there is a possibility that the trace when there has been an unauthorized access cannot be surely left. In addition, when the illegally peeled seal is reused, there is a possibility that further damage is expanded.

  In addition, the gaming machine described in Patent Document 2 can read the information on the IC chip when the tape-type inlet antenna is peeled off without being cut by a plurality of chemicals, and when there is an unauthorized access without fail. There was a possibility that the trace could not be left.

  The present invention has been made in view of the above circumstances, and can effectively confirm the traces of such fraudulent acts while effectively preventing fraudulent acts on the electronic board. It is an exemplary problem to provide an electronic board unit and a gaming machine that can contribute to prevention and early detection of fraud.

  In order to solve the above problems, an electronic substrate unit as an exemplary aspect of the present invention includes a plurality of substrate cases that cooperate to enclose an electronic substrate, a coupling member that couples the substrate cases, and a plurality of substrates. A sealing member fixed so as to straddle a plurality of substrate cases in order to prevent the separation at the joint of the case, and the sealing member includes an information unit having information that can be read by a reader. The part is fixed above the coupling member.

  According to the present invention, since the separation of the substrate case is prevented by the coupling member that couples the substrate cases, it is necessary to release the coupling of the coupling member and separate the substrate case in order to access the electronic substrate from the outside. There is. Further, an information portion of the sealing member is disposed above the coupling member. Therefore, in order to access the electronic substrate from the outside, the information section must be destroyed or destroyed to release the coupling member, and the substrate case must be separated. When the information part of the sealing member is destroyed or damaged, the information in the information part cannot be read. 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.

  Moreover, the information part should just have the information which can be read with a reader | leader, for example, can illustrate RF tag (an IC chip is included) used for RFID (Radio Frequency Identification). The information section is a concept that includes not only the tag itself but also an antenna for transmitting information in a tag that transmits information by radio waves. Moreover, the information part should just contain the information which can be read with a reader | leader not only the tag which transmits information by an electromagnetic wave, For example, a barcode is also included.

  The state in which the information in the information part is substantially unreadable is not only in a state in which the information in the information part is technically unreadable, but in a normal use state, but in a use state different from normal Is a concept that includes a readable state. The use state different from the normal here refers to, for example, a state in which reading can be performed only by dramatically improving the sensitivity of the reader, or reading only by making the distance between the reader and the information unit closer to those in the normal use state. It is possible.

  Moreover, the upper direction in this invention does not necessarily mean the upper direction in a perpendicular direction, but means the positional relationship which one covers the other in the mutual relative position. For example, the positional relationship between the information part and the coupling member may be such that the information part is arranged so as to substantially block the direction in which unauthorized access to the coupling member is made. Specifically, in a coupling member (for example, a screw member) configured to be able to release the coupling by applying a detachable tool from the outside, an information section is arranged at an application position of the detachable tool with respect to the coupling member. Just do it.

  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.

  In addition, the electronic board unit includes an RF tag in which information that can be read by a reader is embedded, and an antenna unit of the RF tag, and at least the antenna unit of the RF tag and the antenna unit includes: It is arranged above the coupling member, and is configured such that the information of the RF tag becomes substantially unreadable by releasing the coupling by the coupling member.

  Since the antenna portion of the RF tag is disposed above the coupling member, when the substrate case is separated to access the electronic substrate from the outside, the antenna portion is broken or damaged. The RF tag stores information and has a relatively high strength. On the other hand, the antenna unit only needs to be able to transmit radio waves, and is often more fragile than RF tags. By disposing the antenna unit above the coupling member, when accessed to release the coupling member, the antenna unit can be more reliably destroyed or damaged, leaving a trace of unauthorized access. It becomes possible.

  Further, at least one of the plurality of substrate cases is provided with a positioning portion for determining the position of the sealing member, and the information member is positioned by positioning the sealing member based on the positioning portion. It is comprised so that it may be arrange | positioned above a coupling member. By providing the positioning part of the sealing member, the sealing member can be easily positioned and the information part can be reliably arranged above the coupling member.

  Here, the positioning portion is a portion serving as a reference for determining the position of the sealing member when the sealing member is disposed. Specifically, it is a rib formed protruding from the surface of the substrate case, and a configuration in which the information unit is arranged above the coupling member by arranging the sealing member along the rib can be exemplified. The positioning unit may be a component or the like mounted on the substrate case, or a part (for example, a corner) of the substrate case may function as the positioning unit. Furthermore, the positioning portion only needs to be provided in at least one of the plurality of substrate cases. For example, the positioning portion may be provided only in one of the substrate cases, or may be provided in both of the plurality of substrate cases. Good.

  The sealing member further has identification information visible from the outside, and the identification information is desirably arranged above the vicinity of the joints of the plurality of substrate cases. When the sealing member has the information section and the identification information, it is possible to grasp that the electronic board unit has been illegally replaced by the identification information when the electronic board unit is replaced. Further, since the identification information is arranged above the vicinity of the joint of the substrate case, the identification information portion is easily damaged when the substrate case is separated. The identification information is a portion that is visually recognized by the examiner and is a relatively conspicuous portion. By making this relatively conspicuous identification information easy to break, it becomes easy to detect that it has been opened illegally.

  Furthermore, by making the joint portion between the substrate cases non-linear, it becomes difficult to cut the substrate case in a straight line with a cutter or the like, and the cut surface can be made conspicuous. Further, if the substrate case is forcibly separated in a state where the sealing member is fixed, the sealing member is cut in a state of being fixed to each substrate case, and the sealing member is easily separated. That is, when the substrate case is separated, the sealing member is more easily broken or cut, and it is possible to more reliably leave a trace due to illegal separation.

  The electronic board unit further includes a cover member that covers the sealing member, and the cover member is configured to be detachable from the board case, and is sealed above the coupling member when being removed from the board case. It is desirable to have a contact part that breaks the member and makes the information in the information part by the reader substantially unreadable.

  By providing the cover member, the joint between the substrate cases can be covered with the cover member, and the separation of the substrate cases can be made difficult. Further, the sealing member can be protected by the cover member, and the sealing member can be prevented from being damaged except for unauthorized access. In addition, in the cover member which covers the sealing member which has identification information, it is desirable to provide the window part for visually recognizing identification information in a cover member. By providing the window portion, it is possible to ensure the visibility of the identification information while protecting the identification information by the cover member.

  The cover member is typically a resin member formed of a translucent resin material such as acrylic or polycarbonate. Of course, the cover 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 cover member may be bonded or welded across a plurality of substrate cases, locked in a non-removable manner with locking hooks, or crimped.

  Also, by providing a contact portion that breaks the sealing member when it is removed from the substrate case, when the cover member is removed to separate the substrate case, the contact portion breaks the sealing member, and the information portion by the reader is substantially It becomes impossible to read information. Therefore, even when the cover member is removed, a trace of the unauthorized access remains on the sealing member upon unauthorized access to the electronic board.

  The state in which the sealing member is broken by the contact portion is a state in which the sealing member is broken, torn, or damaged, and does not necessarily mean a divided state. It includes all situations that are impossible.

  As a specific configuration, the coupling member protrudes from the substrate case to the contact portion side, and when the cover member is removed from the substrate case, the contact portion contacts the information portion above the coupling member to break the sealing member. It may be configured. By projecting the coupling member and projecting the information part to the contact part side, the information part can be easily brought into contact with the contact part when the cover member is removed, and the information part can be damaged or destroyed by the contact part. .

  As another specific configuration, a space is formed between the coupling member and the sealing member, and when the cover member is removed from the substrate case by projecting the contact portion toward the sealing member, the contact portion is brought into the space. You may comprise so that it may penetrate | invade and a sealing member may be broken. Also with this configuration, when the cover member is removed, the sealing member is broken by the contact portion, and reading of the information portion can be made substantially impossible.

  Moreover, it is desirable that the electronic substrate unit further includes a residual trace portion that retains the engagement state between the substrate cases and leaves a trace when the engagement is released. If it is going to cancel | release coupling | bonding of a coupling member, the information part of a sealing member will be damaged or destroyed, and an unauthorized access can be detected. However, a part of the sealing member is damaged, and it is necessary to replace it with a new sealing member. In addition, when the information on the sealing member corresponds to each substrate case, it is necessary to replace the electronic substrate unit, and the electronic substrate unit whose sealing member is damaged may be discarded.

  In order to reduce the number of such sealing members and electronic board units to be discarded, it is preferable to provide a trace remaining portion for leaving a trace of disengaged engagement. The trace remaining portion holds the engagement state between the substrate cases, and the release state of the residual trace portion needs to be released to release the engagement state. Accordingly, it is possible to take time and labor for the operation of releasing the engagement of the substrate case, and it is possible to prevent unauthorized opening of the substrate case. Furthermore, the presence of the trace remaining portion makes it possible to recognize that a trace remains even if the person who opens the substrate case illegally releases the engagement. In other words, by providing the remaining trace portion, it is possible to effectively suppress the illegal act of releasing the engaged state, prevent the substrate case from being opened illegally, and reduce the number of control boards to be discarded.

  In addition, a gaming machine as another exemplary aspect of the present invention is a gaming machine including a gaming device body that realizes a game, a gaming machine frame that includes the gaming device body, and the electronic board unit described above. The electronic board unit is detachably attached to the gaming machine body or the gaming machine frame.

  According to this gaming machine, since the electronic board unit is provided, it is possible to effectively prevent an unauthorized person 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.

  Note that the gaming device body is a game for a gaming machine. For example, if it is a pachinko game machine, it is a game board that realizes a game by the flow of game media. The reel which implement | achieves a game can be illustrated. In addition, the electronic board unit may be configured to be mounted on the gaming device body or the gaming machine frame, and may be configured to be directly mounted on the gaming device body or the gaming machine frame. A member may be arrange | positioned between game machine frames, and the structure which can be mounted | worn indirectly with respect to a game device body or a game machine frame may be sufficient.

  The gaming machine frame is a frame member or a group of frame members that encloses the gaming apparatus body and surrounds the side and front of the gaming apparatus body. For example, when the gaming machine is a pachinko gaming machine, a housing frame, a machine frame, a front frame, or a combination of these that includes a gaming board as a gaming device body corresponds to the gaming machine frame, and the gaming machine is a slot. In the case of a machine, a cabinet (casing frame and / or front frame) containing a reel (rotating device) as a gaming apparatus body corresponds to the gaming machine frame. Of course, in a gaming machine other than a pachinko gaming machine or a slot machine, a frame member that includes a gaming device body (for example, a gaming board in a coin gaming machine or a game image display device in an arcade machine) that realizes gaming in those gaming machines. Etc. correspond to this gaming machine frame.

  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, since the information part of the sealing member is destroyed or damaged by attempting to release the coupling of the coupling members that couple the substrate cases together, it is possible to reliably leave a trace of unauthorized access. Therefore, while effectively preventing fraudulent acts on the electronic board, the traces can be easily and reliably confirmed when such fraudulent acts are performed, contributing to prevention and early detection of fraud. be able to.

That is, an image control board unit (electronic board unit) can be configured by including an image control board (electronic board), an image control board case (board case), a sealing seal, and a protective cover. Similarly, a payout control board (electronic board), a payout control board case (board case), a sealing sticker and a protective member are used to form a payout control board unit (electronic board unit), a power supply board (electronic board), A power supply board unit (electronic board unit) can be configured by including a power supply board case (board case), a sealing seal, and a protective member.

  Hereinafter, the structure of the main control board unit (electronic board unit) according to Embodiment 1 of the present invention will be described with reference to FIGS. In the following description, the up / down and front / rear / left / right directions are defined based on the direction of the player when viewing the pachinko machine 2 and are appropriately illustrated in the figure.

  FIG. 3 is a plan view of the main control board unit U, and FIG. 4 is an exploded perspective view of the main control board unit U. The main control board case 35 includes a main body case (board case) 35a that is detachably fixed to the back side of the game board 6, and a lid case (board case) 35b that is detachably fixed to the main body case 35a. Two substrate cases are provided, and both of them cooperate to enclose the main control substrate 34 therein. The main control board 34 is fixed to an opening formed on the inner surface side of the lid case 35b, and the lid case 35b and the main body case 35a are engaged with each other so that the main control board 34 is accommodated in the main control board case 35. It has become. In this accommodated state, the main control board 34 cannot be contacted from the outside.

  An electronic component 34b including an electronic device such as a ROM, a RAM, and a CPU, a connector, and the like is provided on the surface of the main control board 34 (the surface here includes the case where it is the front side and the case where it is the rear side). Has been implemented. Around the main control board 34, a fixing hole 34a as a fixing portion is formed. By inserting a fixing screw into the fixing hole 34a from the rear side of the main control board 34 and screwing the fixing screw and the screw hole of the lid case, the main control board 34 is fixed in the lid case 35b. It has become.

  A hinge portion is provided on the lower side of the main control board case 35. The hinge portion includes a shaft portion (not shown) along the lower side wall surface of the main body case 35a, and an arcuate claw portion 35e on the side of the lid case 35b that is locked to the shaft portion. The shaft portion is formed in the main body case 35a, and the arc-shaped claw portion 35e is formed in the lid case 35b. The lid case 35b is supported so as to be swingable about the shaft portion with respect to the main body case 35a. The lid case 35b rotates relative to the main body case 35a, thereby opening the opening of the main control board case 35. An open state and a closed state are realized.

  A sealing portion as a trace remaining portion is formed on the upper portion of the main control board case 35. The sealing portion is arranged on the upper and lower sides of the main control board case 35 on the left and right sides with an unauthorized opening detection structure to be described later interposed therebetween. The sealing portion includes a main body caulking portion 35g formed to protrude from the upper wall surface of the main body case 35a, a lid caulking portion 35k connected to the lid case 35b via a connecting member 35h, a main body caulking portion 35g, and a lid. And a sealing piece 35m that can be accommodated between the caulking portion 35k.

  The sealing piece 35m is accommodated in each caulking portion in a first state in which the surface on which the characters “LOCK” are printed is positioned forward or in a second state in which the surface is positioned rearward. When the sealing piece 35m is disposed in the main body caulking part 35g in the first state and the substrate case is closed, the sealing piece 35m is fitted with the main body caulking part 35g and the lid caulking part 35k, and the main control board case It becomes the sealing state in which the closed state of 35 is maintained. On the other hand, when the sealing piece 35m is arranged in the second state in the main body caulking portion 35g and the substrate case is closed, the sealing piece 35m does not fit into the main body caulking portion 35g and the lid caulking portion 35k, and the substrate case is closed. State is not preserved.

  Therefore, when the main control board case 35 is sealed in the closed state, one of the sealing pieces 35m is placed in each crimping portion as the first state, and the other sealing piece 35m is placed in the second state as each crimping portion. Place the board case in the closed state. As a result, the main control board case 35 is in a sealed state.

  It is difficult to release the sealed state by sealing the main control board case 35 with such a sealing portion. In order to open the main control board case 35, the sealing piece in the first state is used. It is necessary to cut | disconnect the connection member 35h connected with the lid crimping part 35k which accommodated 35m, and to cut | disconnect this lid crimping part 35k from the lid case 35b. Therefore, after opening the main control board case 35, it is possible to detect that the main control board case 35 has been opened illegally by leaving a trace of cutting the connecting member 35h.

  However, the trace of cutting the connecting member 35h cannot be detected without viewing the main control board case 35, and there is a possibility that it cannot be detected at an early stage that the main control board case 35 has been illegally opened. As a countermeasure against this, the main control board unit U according to the first embodiment includes an unauthorized opening detection structure together with the sealing portion.

  Further, a main body sealing portion as a trace remaining portion is formed on the right side portion of the main control board case 35. The main body sealing portion has a cover caulking portion 35k formed in the lid case 35b and a board caulking portion (not shown) provided on a mounting board on the back side of the game board 6 having the same structure as the main body caulking portion. And a sealing piece 35m accommodated in each caulking portion. The main body sealing board can hold the main control board unit U and the game board 6 in a fixed state, and also leave a trace when the main control board unit U is removed, and the main control board unit U is illegal. Can be detected.

  On the upper side of the main control board case 35, an unauthorized opening detection structure is provided. The unauthorized opening detection structure is intended to prevent unauthorized opening of the main control board case 35 by an unauthorized person and to leave a trace of the unauthorized opening in the event of unauthorized opening. FIG. 5 is an exploded enlarged view showing the unauthorized open detection structure in an enlarged manner. The unauthorized opening detection structure is provided at a portion where the main body case 35a and the lid case 35b are combined, and has a boundary line (joint) 35f between the cases 35a and 35b.
