Description

  The present invention relates to an electronic board unit, and more particularly to an electronic board unit that can prevent an illegal act on an electronic board contained in a board case.

  In a gaming machine such as a pachinko machine, a bulleted game ball is a game area (an area formed on or near the game board surface and an area for realizing a game or an effect by the flow of the game ball). In the process of flowing down, the game ball turns while colliding with a game nail (also referred to as a gauge) or a windmill in the game area, and the flow direction changes. As a result, if a game ball wins at various winning holes arranged on the game area, a predetermined winning ball is paid out. On the other hand, if a game ball flows into the out port without winning any of the winning holes, the winning ball It will not be paid out. The player enjoys the game by demonstrating his / her skill in the ball or using the chance of the game ball flowing down and expecting the game ball to be won and paid out.

  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 played properly or that some illegal players will be given an unfair advantage. . Therefore, it is necessary to devise such an electronic substrate and its surrounding structure that are difficult to access from the outside.

  For example, Patent Document 1 describes a gaming machine in which an electronic substrate is enclosed by a plurality of substrate cases and a seal seal is pasted so as to straddle the boundaries of the plurality of substrate cases. The seams of the plurality of substrate cases are formed in a non-linear shape, and the sealing seal is attached so as to cover the seams of the plurality of substrate cases. Thus, by applying the seal seal over the non-linear seam, it becomes difficult to cut the seal seal without leaving a trace along the seam using a cutter or the like, and the seal seal is cut. It is possible to easily leave a trace when hitting.

JP 2006-87807 A

  However, the gaming machine described in Patent Document 1 may open the board case by cutting the sealing sticker, and it is difficult to reliably prevent unauthorized access to the electronic board.

  The present invention has been made in view of the above circumstances, and provides an electronic substrate unit that can prevent illegal opening of a substrate case that encloses an electronic substrate and can effectively prevent illegal acts on the electronic substrate. This is an exemplary problem.

  In order to solve the above-described problems, an electronic board unit according to an exemplary aspect of the present invention prevents a separation between a plurality of board cases that collectively contain an electronic board and a joint of the plurality of board cases. A sealing member fixed so as to straddle a plurality of substrate cases, and the sealing member includes an information portion having information that can be read by a reader. The substrate case is fixed to the substrate case. An erected portion is provided which is erected along the entire outer periphery of the sealing member.

  In order to access the electronic substrate from the outside, it is necessary to separate a plurality of substrate cases. However, since the sealing member is fixed so as to straddle a plurality of substrate cases at the joint of the substrate case, the sealing member is peeled off from the substrate case or the sealing member is cut to release the sealing by the sealing member Otherwise, the substrate case cannot be separated. Further, a standing portion is provided along the entire outer periphery of the sealing member fixed to the substrate case, and it is difficult to access the sealing member fixed to the substrate case by this standing portion, and illegal acts on the electronic substrate are prevented. Can be prevented.

  For example, in order to open the electronic case illegally, a sharp member such as a cutter may be inserted between the sealing member and the substrate case at an acute angle, and the sealing member may be broken to release the sealing by the sealing member. . However, since the entire outer periphery of the sealing member is covered by the standing portion, it is difficult to insert a sharp member between the sealing member and the substrate case at an acute angle, and the sealing member is peeled off from the substrate case without damaging the sealing member. I can't.

  In order to peel off the sealing member in a state where the sealing member is covered with the standing portion, a sharp member is inserted between the sealing member and the substrate case substantially vertically. Compared with the case where a sharp member is inserted at an acute angle between the sealing member and the substrate case, the possibility of breakage of the sealing member is increased, and a trace of unauthorized access can be left on the sealing member.

  When the sealing member is torn or damaged, the trace can be confirmed visually. Furthermore, reading of information in the information section by the reader becomes virtually impossible, and the trace of unauthorized access remains on the sealing member. Therefore, it is possible to prevent unauthorized access to the electronic board, to leave a trace when unauthorized access is made, and to suppress the spread of damage due to unauthorized activities.

  In addition, the standing part should just be erected with respect to the fixed surface to which the sealing member in a board | substrate case is fixed, may be projected with respect to the surface of a board | substrate case, and may be provided in the surface of a substrate case Alternatively, a recessed portion that is recessed may be provided, and the bottom surface of the recessed portion may be used as a fixed surface, and the wall portion surrounding the recessed portion may be configured as a standing portion.

  The sealing member is typically a so-called sealing seal, but is not limited to a seal. The sealing member only needs to be a member that can prevent separation at the joint of the substrate case. 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.

  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 means not only the state in which the information in the information part is technically unreadable, but also in a normal use state, but a use state different from normal Is a concept including a readable state. The use state different from the normal here is, for example, a state in which reading can be performed only by dramatically improving the sensitivity of the reader, or a case in which the distance between the reader and the information unit is closer than the normal use state. It is readable.

  An electronic board unit according to another exemplary aspect of the present invention includes a plurality of board cases that cooperate to enclose the electronic board and a plurality of boards to prevent separation at the joint of the plurality of board cases. A sealing member fixed so as to straddle the case, and the sealing member includes an information portion having information that can be read by a reader. In the vicinity of the corner portion of the sealing member fixed to the substrate case, A standing part standing from the case is provided.

  For example, in order to open the substrate case illegally, it is conceivable to insert a sharp member between the corner portion of the sealing member and the substrate case, and gradually peel the sealing member from the corner portion from the corner portion. When peeling a sealing member from a corner | angular part, compared with the case where a sealing member is peeled from a side, possibility that a sealing member will be peeled without being torn or damaged becomes high.

  However, by providing a standing portion near the corner of the sealing member, the corner that is easily accessed when the sealing member is illegally peeled is protected, and the sealing member is prevented from being peeled without being damaged. be able to.

  In addition, the standing part should just be comprised so that the access with respect to the corner | angular part of a sealing member may be prevented, may be arrange | positioned so that the side of a corner | angular part may be covered, and two sides adjacent to a corner | angular part You may arrange | position so that the side of a side may be covered.

  Moreover, the standing part of the electronic substrate unit according to the present invention may be configured so as to be disposed in the vicinity of the corner of the sealing member and not disposed in the vicinity of the corner. For example, by providing a standing portion so as to cover the entire outer periphery of the sealing member, unauthorized access to the sealing member can be prevented. However, when the sealing member is fixed to the substrate case, the standing portion becomes an obstacle, and the efficiency of the fixing operation of the sealing member may be reduced, or the accuracy of the fixing position of the sealing member may be reduced.

  On the other hand, by arranging the standing part only in the vicinity of the corner part of the sealing member and not arranging the standing part other than in the vicinity of the corner part, it effectively protects the vicinity of the corner part that is easily accessed illegally. Further, it is possible to facilitate access to portions other than the vicinity of the corner portion of the sealing member (for example, a portion along the side), and to improve operability when the sealing member is fixed.

  As a specific configuration of the standing part, the standing part is arranged in the vicinity of the square of the rectangular sealing member, and the standing part is provided at a part along the side of the sealing member between the corners. A configuration not provided can be exemplified. According to the standing part configured in this way, since the standing part is not provided along the side of the sealing member, the fixing member can be fixed from the side of the fixing surface. The operability can be improved. On the other hand, access to the corners of the sealing member can be prevented while being fixed to the substrate case.

  The electronic board unit according to the present invention may further include a cover part that is connected to the standing part and covers at least a part of the sealing member that is fixed to the board case. By providing the cover portion, it is possible to prevent access to the sealing member from above the sealing member as well as access from the outer peripheral side of the sealing member fixed to the substrate case and the vicinity of the corner portion. Therefore, unauthorized access to the sealing member can be more effectively prevented.

  In addition, since the trace of the unauthorized access with respect to a sealing member remains in the sealing member itself or the substrate case to which a sealing member is fixed, it is desirable for the sealing member to be visible from the outside. Therefore, the cover portion is preferably made of a transparent material that allows the sealing member to be visually recognized. Furthermore, by using a transparent material for the standing portion, it is possible to improve the visibility of the sealing member and the substrate case to which the sealing member is fixed, and contribute to early detection of illegal acts by visual inspection.

  Moreover, the cover member should just be arrange | positioned so that the upper part of at least one part of a sealing member may be covered, may be arrange | positioned so that the whole surface of a sealing member may be covered, and it opposes the surface of a sealing member Thus, they may be arranged close to each other, and various configurations can be employed. In addition, it is possible to enhance the security effect by covering the entire surface of the sealing member with the cover member and fixing the cover member to the substrate case. As a fixing method, it may be fixed by screws or may be fixed by caulking.

  By providing a cover member so as to cover the entire sealing member, not only access to the corners of the sealing member but also access to the entire sealing member can be prevented, and the act of peeling the sealing member with a solvent or the like can be prevented. can do. Furthermore, by fixing the cover member by caulking or the like, it is possible to take time and labor for the operation of releasing the engagement of the substrate case, and it is possible to suppress unauthorized opening of the substrate case.

  An electronic board unit according to another exemplary aspect of the present invention includes a plurality of board cases that cooperate to enclose the electronic board and a plurality of boards to prevent separation at the joint of the plurality of board cases. A sealing member affixed so as to straddle the case, and the sealing member includes an information unit having information readable by a reader, and an adhesive layer for bonding to the substrate case. The fixing surface to which the sealing member is fixed is rough so that the surface roughness does not exceed the thickness of the adhesive layer.

  The sealing member is fixed via a fixing surface fixed to the substrate case and an adhesive layer. The adhesive layer has a certain thickness, and the adhesive strength increases in proportion to the contact area within the thickness range. Since the surface roughness of the fixing surface of the substrate case is rough within the range not exceeding the thickness of the adhesive layer, the contact area between the fixing surface and the adhesive layer is increased, and the fixing surface and the sealing member are bonded. You can increase your power. By increasing the adhesive force of the sealing member, the sealing member is hardly peeled off from the substrate case, and unauthorized opening of the substrate case can be prevented.

  The surface roughness of the fixed surface can be formed, for example, by processing fine protrusions during resin molding in a resin substrate case. Moreover, you may provide the structure which roughens the surface roughness of a fixed surface, and the above-mentioned standing part together. Unauthorized access to the sealing member can be prevented, and even when unauthorized access is made, the sealing member is more difficult to peel off, and unauthorized opening of the substrate case can be effectively prevented. The operation of releasing the engagement of the substrate case can be time-consuming and time-consuming, and unauthorized opening of the substrate case can be suppressed.

  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, by providing a standing portion that makes it difficult to illegally access the sealing member fixed across the substrate cases, the sealing member is hardly peeled off, thereby preventing unauthorized opening of the substrate case. be able to. Further, by making unauthorized access to the sealing member difficult, it is possible to prevent the sealing member from being peeled without being damaged, and to easily leave a trace of unauthorized access.

  Further, by increasing the adhesive force between the sealing member and the fixing surface of the substrate case, it is difficult for the sealing member to be peeled off from the substrate case, and it takes time and effort to remove the sealing member and to release the substrate case. And unauthorized opening of the substrate case can be suppressed. Further, even when the sealing member is forcibly peeled off, the sealing member can be damaged by the adhesive force, and a trace when an illegal act is performed can be left.

  That is, according to the present invention, it is possible to easily check the traces of such fraudulent activities while preventing fraudulent acts on the electronic board effectively, and to prevent and prevent fraudulent acts. Can contribute to discovery.

Hereinafter, a main control board unit (electronic board unit) U1 according to the first embodiment 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 U1, and FIG. 4 is an exploded perspective view of the main control board unit U1. 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. There are two substrate cases, and both of them cooperate to enclose the main control substrate 34 inside. 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 connection connector, and the like is provided on the surface of the main control board 34 (the surface here includes a case where it is the front side and a case where it is the rear side). Has been implemented. Around the main control board 34, a fixing hole 34a as a fixing surface 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 a screw hole (not shown) of the lid case 35b, the main control board 34 is attached to the lid case 35b. It is designed to be fixed inside.

  A hinge portion is provided on the lower side of the main control board case 35. The hinge portion is configured to include a shaft portion (not shown) along the lower side wall surface of the main body case 35a, and an arcuate arc-shaped claw portion 35e locked to the shaft portion. The lid case 35b is formed, and the arc-shaped claw portion 35e is formed in the main body case 35a. 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 disposed in the main body caulking portion 35g in the second state 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 unless the main control board case 35 is visually recognized, and there is a possibility that it cannot be detected early that the main control board case 35 has been illegally opened. As a countermeasure against this, the main control board unit U1 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 includes a lid caulking portion 35k formed in the lid case 35b, a board caulking portion (not shown) that has the same structure as the main body caulking portion and is fixed to the back side of the game board unit 5, Sealing pieces (not shown) accommodated in the respective crimping portions.

The fixed surface 35p is disposed across the front surface, the upper surface, and the rear surface of the main control board case 35, and is a bottom surface of a hollow portion that is recessed with respect to the surface of the main control board case 35. The bottom surface of the recessed portion serves as a sealing seal fixing surface 35p, and the wall surface that separates the recessed portion functions as the standing portion 42. The standing portion 42 covers the entire outer periphery of the seal seal 41 and is erected with respect to the surface of the seal seal 41 in a state where the seal seal 41 is affixed. By providing the standing portion 42, it is possible to prevent the seal seal 41 from being peeled without being damaged.

  Even if it is attempted to insert a sharp blade such as a cutter between the seal seal 41 and the fixed surface 35p at an acute angle in order to remove the seal seal 41 illegally, the entire outer periphery of the seal seal 41 is covered by the standing portion 42. Therefore, the blade cannot be inserted at an acute angle with respect to the seal seal 41, and the blade is inserted substantially perpendicular to the seal seal 41. When the cutter is inserted at an acute angle between the seal seal and the fixed surface, the seal seal may be peeled without being damaged, but when the cutter is inserted substantially perpendicular to the seal seal 41 In this case, there is a high possibility that the seal seal is broken during the peeling process.

  That is, by providing the upright portion 42, it is possible to prevent the sealing seal 41 from being peeled without being damaged by being inserted at a sharp angle between the sealing seal 41 and the fixed surface 35p.
