Description

  The present invention relates to an electronic board unit and a gaming machine, and more particularly to a board case 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. Thus, 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-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 enclose an electronic board and a plurality of board cases together. Preferably, the electronic board unit includes a sealing member fixed so as to straddle the plurality of board cases, and a cover member covering the sealing member, and the sealing member includes an information unit having information readable by a reader. The cover member is configured to be detachable from the substrate case, and when the cover member is removed from the substrate case, the contact member substantially breaks the seal member so that the information in the information unit cannot be read by the reader. Have

  In order to access the electronic substrate from the outside, it is necessary to separate the substrate case. At the joint of the substrate cases, a sealing member is fixed so as to straddle the plurality of substrate cases, and the sealing member is covered with a cover member. The cover member is provided with a contact portion that breaks the sealing member when removed from the substrate case. Therefore, if the cover member is removed in order to separate the substrate case, the contact part breaks the sealing member, and the information in the information part cannot be read by the reader substantially. 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 besides the tag which transmits information by an electromagnetic wave, for example, contains a barcode.

  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.

  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.

  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.

  The information unit includes an RF tag in which information that can be read by the reader is embedded, and an antenna unit that transmits the information of the RF tag by radio waves. The contact unit is used when removing the cover member from the substrate case. By breaking the sealing member, the antenna portion is broken or broken, and the information of the RF tag is made substantially unreadable.

  When removing the cover member from the substrate case, the contact portion is configured to break the sealing member and damage or destroy the antenna portion. Therefore, when the substrate case is separated to access the electronic substrate from the outside, the RF tag This information becomes substantially unreadable. Usually, 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 configuring the antenna portion to be damaged or destroyed by the contact portion, the antenna portion can be more reliably destroyed or damaged when the cover member is removed from the board case and accessed, and traces of unauthorized access can be obtained. It becomes possible to leave.

  Further, the information part is arranged so as to protrude toward the contact part side of the cover member, and the contact part comes into contact with the information part arranged so as to protrude when the cover member is removed from the substrate case so as to break the sealing member. It may be configured. By disposing the information part included in the sealing member so as to protrude toward the contact part side of the cover member, the information part included in the sealing member and the contact part can be easily contacted when the cover member is removed, and the information part is provided by the contact part. Can be damaged or destroyed. Therefore, when the cover member is removed, it is possible to make it impossible to read the information section.

  The configuration in which the information unit is protruded to the contact side is a configuration in which a floating structure is provided on the substrate case to which the sealing member is fixed, or a sealing member is formed so as to project the information unit by forming a space below the information unit. The structure to fix can be illustrated. Furthermore, as a specific configuration having a floating structure, a configuration in which a protruding portion is formed on the surface facing the contact portion in the substrate case to which the sealing member is fixed, and an information portion is disposed on the protruding portion, or a sealing member The structure which joins components to the surface facing the contact part in the board | substrate case to which this is fixed, forms a protrusion part, and arrange | positions an information part on this protrusion part can be illustrated.

  It further includes a coupling member for coupling the substrate cases to each other, and the coupling member is disposed so as to protrude from the surface of the substrate case facing the cover member to the contact portion side, and the information portion of the sealing member is fixed above the coupling member. It may be configured as described. By arranging the coupling member so as to protrude toward the contact portion and fixing the information portion of the sealing member above the coupling member, the information portion included in the sealing member and the contact portion are easily brought into contact when the cover member is removed. In addition, the information part can be damaged or destroyed by the contact part. Therefore, when the cover member is removed, it is possible to make it impossible to read the information section.

  Further, 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. Further, an information portion of the sealing member is disposed above the coupling member. 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. Accordingly, even when the coupling by the coupling member is released, the information portion of the sealing member is destroyed or damaged, so that it is possible to leave a trace of unauthorized opening more reliably.

  The substrate case to which the sealing member is fixed is formed with a recess, the information portion is disposed above the recess, and the contact portion is disposed so as to protrude toward the sealing member. When removing a member, it may be comprised so that it may penetrate | invade in a hollow part and torn a sealing member. By forming a recess in the substrate case to which the sealing member is fixed and placing the information section on the recess, a space can be formed below the information section. The contact portion is configured to break the sealing member by entering a hollow portion that becomes a space below the information portion when the cover member is removed from the substrate case. In this way, a hollow portion serving as a space is provided below the information portion, and the sealing member is reliably broken by allowing the contact portion to enter the hollow portion, and the reading of the information portion is substantially performed when the cover member is removed. It can be impossible.

  Here, the recessed portion is formed so as to be recessed from the surface of the substrate case to which the sealing member is fixed, and to be formed so that a space is provided below the fixed information portion. Specifically, it may be a recessed portion whose planar position is lower than the surface of the substrate case, or may be a hole formed through the surface of the substrate case.

  Further, the cover member is configured to be elastically deformed in a direction in which the contact portion is separated from the information unit when being attached to the substrate case, and is configured to be released from the elastic deformation when being removed from the substrate case. It may be. When the cover member is mounted on the board case, the contact portion is elastically deformed so as to be separated from the information portion, so that the buffer between the contact portion and the information portion is prevented and the information portion is not damaged or destroyed by the contact portion. can do. On the other hand, when removing the cover member from the board case, the elastic deformation that separates the contact portion from the information portion is released, so that the contact portion and the information portion interfere with each other, and the information portion is damaged or destroyed by the contact portion. be able to.

  The elastic deformation of the cover member such that the contact portion is separated from the information portion may be a deformation caused by an external force applied by an operator who wears the cover member, or a cover when the cover member is mounted on the substrate case. The movement trajectory of the member is different from the movement trajectory of the cover member when the cover member is removed from the substrate case, and a projection that elastically deforms the cover member is provided on the movement trajectory of attaching the cover member to the substrate case. You may comprise so that it may elastically deform. Furthermore, the elastic deformation may be configured such that the entire cover portion is elastically deformed, or only a part of the cover member (for example, the contact portion) may be elastically deformed.

  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 the cover member is removed from the substrate case, the information part of the sealing member is damaged or destroyed, and 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 stored in the information part of the sealing member is in the form of individual substrate cases, it is necessary to replace the electronic substrate unit, and the electronic substrate unit whose sealing member is damaged may be discarded. is there.

  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 part holds the engagement state between the first housing member and the second storage member, and the release state of the residual trace part 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 game device body is a game machine that realizes a game in a game machine, for example, a pachinko machine, a game board that realizes a game by the flow of game media, and a slot machine, by a combination of pictures. The reel which implement | achieves a game can be illustrated. The control board case 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.

  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 removing the cover member that covers the sealing member that is fixed across the substrate cases, the information portion of the sealing member is destroyed or damaged, so that a trace of unauthorized access can be reliably left. 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.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a front view of a pachinko machine 2 as a gaming machine according to Embodiment 1 of the present invention. FIG. 2 is a rear view of the pachinko machine 2 shown in FIG.

The frame body 3 is configured by including a decorative frame 12 that is supported by the hinge portion 22 so as to be able to be opened and closed forward and holds the front glass 10 and a decorative member 32 that decorates the front glass 10. The front glass 10 is a transparent member for allowing the player to visually recognize the game board 6 held inside the frame 3 from the front.

  The storage tray 14 is a tray member disposed on the front surface of the pachinko machine 2 to store the player's ball, and has an upper tray 14a and a lower tray 14b in the present embodiment. The upper plate 14a has a ball discharge button 14c and is disposed below the game board 6, that is, a lower portion of the decorative frame 12, and the lower plate 14b is disposed further below the upper plate 14a.

  The game board unit has a game board 6 in which a center accessory 7 is arranged at substantially the center on the game board surface (front surface) 6a side, and a large number of game nails are also arranged on the game board surface 6a. A symbol display device 7a is disposed at the center of the center accessory 7, and an opening 7d for exposing a display screen (video display surface) 7b of the symbol display device 7a is formed.

  The symbol display device 7a is composed of, for example, a liquid crystal display device, an organic EL display, an LED, etc., and is arranged so that the player can see from the game board surface 6a side, and displays a video on the display screen 7b. It is. On the display screen 7b, for example, a display symbol 7c composed of three-digit numbers or characters is displayed as an image so as to rotate or stop. In addition, for example, an effect image as a story tailoring image by a character or the like is also displayed on the display screen 7b.

  The game board 6 is a game apparatus body for configuring the game area 16 for realizing the game by the flow of the ball 23 on the game board surface 6a side so that the player can visually recognize the game board surface 6a from the front. Is held by the frame 3 (in the present embodiment, the machine casing 9 as a part of the frame 3). A rail ornament is attached to the game board surface 6a so as to surround the periphery in a substantially circular shape, and the inner peripheral surface of the rail ornament is disposed so as to stand up with respect to the game board surface 6a. A substantially circular region defined by the inner peripheral surface and facing the inner peripheral surface is a game region 16.

  The game nails collide with the sphere 23 flowing down the game area 16 and change the flow direction thereof, and many of them are arranged in the game area. Further, the game area 16 is provided with a normal winning port 28, a central starting port 29, a central large winning port 31, and the like, and a ball 23 flowing down flows into each inflow port or collides with a game nail. By doing so, it is possible to enjoy the downstream game by the ball 23.

  When the ball 23 is launched by a ball launching device (not shown), the ball 23 travels along the inner peripheral surface of the rail decoration and reaches the upper part in the game area 16. Thereafter, the ball 23 moves along a plurality of passing trajectories and flows down the game area 16 while colliding with the game nail. Some will flow into the regular winning opening 28 and trigger a certain number of prize ball payouts, some will pass through the pass gate 33, and some will not flow into any winning opening at the bottom of the game area. It flows into the out port 30 located and is discharged to the outside of the pachinko machine 2 as an out ball.

  When the ball 23 passes through the passage gate 33, lottery is performed by a state change lottery means (not shown) due to the passage of the passage gate 33. When the lottery result is a win, the opening / closing blades of the central starting port 29 Is opened, and a state where the ball is easy to enter is realized. When it flows into the central starting port 29, the display symbol 7c of the symbol display device 7a starts to rotate due to the inflow, and the display symbol 7c is a predetermined symbol (for example, “7, 7, 7”). If the stop display is made, a big hit in the symbol variation game occurs. The central grand prize opening 31 is opened to accept a large amount of winning balls, and a large amount of prize balls are paid out to the storage tray 14.

  A main control board unit U having a main control board (electronic board) 34 for controlling the entire pachinko machine 2 is arranged on the back side of the game board 6. The main control board unit U has a main control board 34, a main control board case (board case) 35 containing the main control board 34, a sealing seal (sealing member) 41 described later, and a protective cover (cover member) 42.

A game is realized by each control board accommodated in each control board case. Furthermore, an external output terminal plate 39 for outputting game information such as the gaming state of the pachinko machine 2 to the outside is provided on the back side of the game board 6.

  In the first embodiment, the main control board 34 is described as an example, but the same structure can be adopted for other control boards. 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 dispensing control board unit (electronic board unit) having a dispensing control board (electronic board), a dispensing control board case (board case), a sealing seal and a protective cover, a power supply board (electronic board), A power supply board unit (electronic board unit) can be configured by having a power supply board case (board case), a sealing sticker, and a protective cover.

  Hereinafter, the main control board unit (electronic board unit) U 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 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 wall surface of the main body case 35a, and an arcuate arc-shaped 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.

If an attempt is made to remove the protective cover 42 for unauthorized access to the main control board 34, the antenna portion 41c of the seal seal 41 is damaged or destroyed, and the information on the IC chip 41b cannot be read. Therefore, if the main body case 35a and the lid case 35b are separated, the antenna portion 41c of the seal seal 41 is damaged or destroyed, and the traces always remain. Furthermore, since it is possible to detect unauthorized opening by reading the information of the IC chip 41b using a reader, it is possible to easily detect that any number of persons has been opened illegally compared to detection only by visual observation. .

  Further, since the main body case 35a and the lid case 35b are coupled by the first screw portion 35p, the two cases are prevented from being separated, and access to the main control board 34 from the outside is prevented. The seal seal 41 is pasted so as to cover the first screw portion 35p, and if the first screw portion 35p is to be uncoupled in order to separate the main body case 35a and the lid case 35b, the seal seal 41 The antenna portion 41c is cut, and the information on the IC chip 41b cannot be read. Therefore, when the main body case 35a and the lid case 35b are separated, the antenna portion 41c of the seal seal 41 is damaged or destroyed, and an improper access trace always remains. That is, the main control board case unit U according to the first embodiment removes the protective cover 42 from both the cases 35a and 35b, and tries to release the coupling by the first screw portion 35p. Since the part 41c is damaged or destroyed, it is possible to reliably leave a trace of unauthorized opening.
