Description

  The present invention relates to a board case unit that houses a control board used for controlling a gaming machine.

  A gaming machine such as a pachinko gaming machine is provided with a control board that controls the operation of an electronic component mounted on the gaming machine. For example, a control board called a main control board or a main control board is equipped with a ROM in which game machine control software is written, and has a role as a central control device for overall control of the game machine operation. doing. For this reason, the control board of the gaming machine is likely to be a target of action such as replacement with a counterfeit ROM or addition of an illegal circuit. In order to prevent such dishonest act and provide a fair game, the control board is a board case comprising a case body formed of a transparent resin material and a case lid that can be opened and closed in front of the case body. When the case lid is attached to the case body in a closed state, the engagement portion formed on the case body side and the engagement portion formed on the case lid side are engaged and connected to each other. A caulking structure is provided that locks the case in a closed state and prevents the substrate case from being opened unless the connecting part that connects the case lid (or the case body) and its engaging part is separated using a tool such as a nipper. (For example, refer to Patent Document 1).

  Also, stick a seal sticker with a wirelessly readable IC tag that stores the game machine's unique information, control board identification information, etc. across the boundary between the case body and the case lid. It is also known that the substrate case is sealed with a seal cover member (see, for example, Patent Document 2). If the seal seal is used in this way, the control board is not only housed in the board case and held closed by the caulking structure, but when the seal seal is peeled off to open the board case, the seal seal is broken and visually As a result, it is possible to confirm the broken portion and to read the stored information of the IC tag by a reader or the like, so that a trace when there is an unauthorized access to the substrate case can be left more clearly.

  Thus, the seal seal can contribute to measures against unauthorized opening of the substrate case together with the caulking structure, but it is illegally peeled off by a sophisticated technique (for example, peeled off using a release agent) and reused. This makes it difficult to detect illegal acts such as replacing the substrate case itself. Therefore, the seal cover member that surrounds the seal seal from the outside is provided with a breaking projection for breaking the seal seal so that the seal seal cannot be recovered when the seal cover member is removed when the substrate case is opened. A structure to be destroyed has been proposed (see, for example, Patent Document 3).

JP 2004-65280 A JP 2009-261640 A JP 2010-178903 A

  However, when the substrate case is opened improperly, even if the case member remains in a state where the case member cannot be reused due to remaining traces on at least one of the case body and the case cover, If the seal cover member for breaking the cover can be reused in an intact state, even if the seal seal is replaced with a counterfeit product that looks exactly like the genuine product, Combining intact case members taken out from the substrate case, a new substrate case is created. By reusing the so-called Nikoichi (two 1), the appearance is the same as before opening. It will be restored. As a result, even if the control board is illegally modified, the substrate case itself is not damaged unless the information reading inspection by a reader or the like is performed on the forged seal sticker. There was a problem that the detection of fraud was delayed.

  The present invention has been made in view of such problems, and an object of the present invention is to provide a substrate case unit having a configuration that enables prevention and early detection of fraudulent acts on a control substrate.

In order to achieve such an object, a substrate case unit according to the present invention includes a first case member (for example, the case main body 120 in the embodiment) and a second case member attached to the first case member so as to be openable and closable. (For example, the case lid 130 in the embodiment), and the second case member is moved relative to the first case member in the closing direction in the opening / closing movement direction and held in the closed state, and the case is formed in the closed state. A board case unit (for example, main control board case unit 100 in the embodiment) that houses a control board therein, and includes a sealing sticker that is attached to a first case member and disposed inside the case, and a sealing sticker The first case member is attached to a predetermined position of the first case member in a detachable manner so that the second case member can be opened and closed with respect to the first case member. The seal destruction member that breaks the seal seal in cooperation with the second case member and is separated from the first case member when it is relatively moved in the opening direction in the direction (for example, the seal seal cutter 160 in the embodiment). The first case member has a first coupling portion (for example, the main body side coupling portion 124 in the embodiment), and the second case member is attached to the first case member by closing the second case member. Sometimes when a second coupling part (for example, the lid-side coupling part 134 in the embodiment) that faces and closes to the first coupling part is provided, and the seal breaking member is attached to the first case member with the second case member closed. A third coupling portion (for example, the cutter side coupling portion 166 in the embodiment) that is interposed between the first coupling portion and the second coupling portion and is fixed to the first coupling portion and the second coupling portion. And the first bond It is configured to have a breakdown portion capable of separating the anchor site of the first casing member and the third coupling portion in being breakable formed externally the first coupling portion. The “adhesion” defined here is a concept including welding, adhesion and the like.

  According to the present invention, it is possible to contribute to prevention and early detection of fraud by preventing reuse of the substrate case unit.

The caulking member 140 is held in a locked position in which the backward movement (removal direction) is restricted by the engagement between the lock pin 143 and the main body side lock hole 122a.

  When the shaft portion 141 of the caulking member 140 is thus inserted into the main body side lock hole 122a and the lid side lock hole 132a and held in the locked position, the case lid 130 cannot slide to the left and right with respect to the case main body 120, and the case The case lid 130 is connected to the main body 120 in a closed state so that it cannot be removed (cannot be opened). In order to open the substrate case 110 from this state, the connecting portion 132b connecting the lid-side base portion 131 and the lid-side crimping portion 132 of the case lid 130 is cut and engaged with the main body-side crimping portion 122. What is necessary is just to cut | disconnect the lid side crimping part 132 of a state from the lid side base part 131. FIG.

  However, in recent years, fraudulent acts on the substrate case 110 tend to become more sophisticated (for example, reuse of the substrate case 110 called Nikoichi). Therefore, in order to more strictly prevent unauthorized opening of the substrate case 110, the substrate case 110 is provided with a sealing structure together with a caulking structure, and the sealing structure of this embodiment will be described below.

  The sealing structure covers the main body side sealing portion 123 formed integrally with the main body side base portion 121 of the case main body 120, the sealing seal 150 attached to the main body side sealing portion 123, and the sealing seal 150. A seal seal cutter 160 that is detachably attached to the main body side seal portion 123 and a lid side seal portion 133 that is integrally connected to the lid side base portion 131 of the case lid 130 are mainly configured. The main body-side sealing portion 123 and the lid-side sealing portion 133 are arranged to face each other in the front-rear direction in a state where the case lid 130 is closed to the case main body 120. In this opposing state, the main-body-side sealing portion 122 and the lid-side sealing portion 133 A seal seal 150 and a seal seal cutter 160 are accommodated between the seal portion 132.

  The main body side sealing portion 123 includes a pedestal portion 123a to which the sealing seal 150 is attached, and a pair of engagement wall portions 123b formed above and below the pedestal portion 123a. The outer surface (left and right side surfaces and rear surface) bent in a U-shape in the pedestal portion 123a forms a seal attaching surface 123c for attaching the seal seal 150, and the seal attaching surface 123c is divided vertically. Three slits 123d extend in the left and right directions and are recessed. The slit 123d opens to the left and right sides and the rear, and serves as a passage for allowing movement of the seal seal cutter 160 (destructive protrusion 162 described later). Further, a main body side coupling portion 124 to be welded to the sealing seal cutter 160 is provided at the left end of the main body side sealing portion 123.

  The main body side coupling portion 124 is integrally connected to the left end of the pedestal portion 123a and is formed in a rectangular flat plate shape. In the main body side coupling portion 124, a breaking portion 124a in which a plurality of slits 124b are intermittently arranged in a perforation is formed by punching or the like, and a sealing seal is located inside the breaking portion 124a. A main body side welded portion 124c welded to the cutter 160 is partitioned. The breaking portion 124a is formed so as to surround the body-side welded portion 124c located substantially at the center of the body-side coupling portion in a U-shape, and the body-side welded portion 124c is separated from other portions of the case body 120. doing. The main body side coupling portion 124 is configured such that the main body side welded portion 124c can be separated from the case main body 120 by breaking the breaking portion 124a along the slit 124b.

  As shown in FIG. 6, the seal seal 150 is configured such that an IC tag 152 and an antenna wire 153 connected thereto are attached to a rectangular sheet member 151 while being covered with a transparent resin film 154. A serial number (not shown) as identification information is printed on the surface of the paper sheet member 151. The IC tag 152 is disposed substantially at the center of the surface of the sheet member 151, and the antenna line 153 is disposed along one diagonal line of the sheet member 151. The IC tag 152 is a very small electronic element that stores various information such as information related to the pachinko gaming machine PM, identification information of the main control board 41, and the board via an antenna line 153 arranged in connection therewith. The stored information can be read by the reader even from outside the case 110.

  A jagged cut 151a is regularly formed on the outer edge of the sheet member 151. When the sheet member 151 is peeled off, stress concentration is generated in the valley portion of the cut 151a so that the cut is easily broken. On the other hand, linear cuts 154a are regularly formed on the outer periphery of the resin film 154, and when the seal seal 150 is peeled off, the antenna wire 153 is easily broken along with the resin film 154 along the cuts 154a. As a result, information transmission is disabled.

  The seal seal cutter 160 is formed by a molding means such as injection molding using a colored transparent synthetic resin material (for example, thermoplastic resin), and covers and protects the seal seal 150 in the closed state of the substrate case 110 ( On the other hand, when the substrate case 110 is opened, the seal seal 150 is broken to the extent that it cannot be regenerated. As shown in FIG. 7, the seal seal cutter 160 includes a protective cover 161 that covers the seal seal 150 that is composed of a rear wall 161 a and a left wall 161 b that are orthogonal to each other and that is attached to the pedestal 123 a at the rear and left sides, and a protective cover. Three breaking protrusions 162 formed on the inner surface side of the rear wall 161a of the cover portion 161, a pair of locking protrusions 163 protruding and formed on the outer surface side of the rear wall 161a, and an engagement wall of the main body side sealing portion 123 It has a pair of engagement claws 164 that can be engaged with the portion 123b, and a pair of engagement claws 165 that can be engaged with an engagement arm of a lid-side sealing portion 133 described later.

  The seal seal cutter 160 is configured to be detachable in the front-rear direction and the left-right direction with respect to the body-side seal part 123 of the case body 120. Here, when the seal seal cutter 160 is moved in the front-rear direction and attached to and detached from the main body-side seal portion 123, the fracture protrusion 162 and the seal seal 150 are displaced in the left-right direction and do not contact each other (see FIG. 11). The sealing seal 150 is not broken by the breaking protrusion 162. That is, the seal seal cutter 160 can be attached to and detached from the main body side seal portion 120 without destroying the seal seal 150 at all. On the other hand, when the sealing seal cutter 160 is moved in the left-right direction and attached to and detached from the main body-side sealing portion 123, the fracture protrusion 162 and the sealing seal 150 are overlapped when viewed from the left-right direction (see FIG. 13). The breaking protrusion 162 comes into contact with the seal seal 150 and breaks it. That is, as will be described in detail later, when the sealing seal cutter 160 is slid in the left-right direction (opening direction and closing direction) with the case lid 130 when the substrate case 110 is opened and closed, the sealing seal cutter The seal seal 150 is broken by 160.

  At the left end of the protective cover portion 161, a cutter side coupling portion 166 that is welded to the main body side sealing portion 123 and the lid side sealing portion 133 is provided. The cutter side coupling part 166 is formed integrally with the left wall 161b of the protective cover part 161. The cutter side coupling portion 166 is formed in a rectangular flat plate shape whose width (long side) in the vertical direction is slightly smaller than that of the main body side coupling portion 124. The cutter side coupling portion 166 overlaps with the main body side coupling portion 124 in the front-rear direction when the seal seal cutter 160 is engaged with the main body side sealing portion 123 of the case main body 120.

  As shown in FIG. 5, the lid-side sealing portion 133 includes a housing portion 133 a formed in a substantially rectangular box shape that is continuous with the lid-side base portion 131 and opened forward, and a pair of recesses provided on the inner surface side of the housing portion 133 a. And a pair of engaging arms 133c formed to project from the inner surface side of the accommodating portion 133a. The locking groove 133 b can be engaged with the locking projection 163 of the seal seal cutter 160, and the engagement arm 133 c can be engaged with the engagement claw 165 of the seal seal cutter 160. Therefore, when the case lid 130 is closed to the case main body 120 and the lid side sealing portion 133 is overlapped back and forth with respect to the main body side sealing portion 123 and the sealing seal cutter 160, the locking protrusion 163 of the sealing seal cutter 160 and Since the engaging claw 165 engages with the locking groove 133b and the engaging arm 133c of the lid-side sealing portion 133, the case lid 130 is moved to the left of the case main body 120 (hereinafter referred to as “open”). The seal seal cutter 160 that is engaged (temporarily fixed) with the main body side sealing portion 123 is separated from the main body side sealing portion 123 and is engaged with each other. It is configured to move together with the lid-side sealing portion 133 (case lid 130).

  At the left end of the lid-side sealing portion 133, a lid-side coupling portion 134 that is welded to the sealing seal cutter 160 is provided. The lid side coupling part 134 is formed integrally connected to the left end of the accommodating part 133a. The lid-side coupling portion 134 has a rectangular box shape having an opening on the front side facing the main-body-side coupling portion 124 and the cutter-side coupling portion 166, and the main-body-side coupling portion 124 and the cutter-side are disposed inside the lid-side coupling portion 134. An accommodation space 134a having a size that can accommodate the coupling portion 166 is formed. On the inner surface of the lid-side coupling portion 134, a lid-side welding portion 134c that is welded to the sealing seal cutter 160 is defined. The case lid 130 is closed to the case main body 120, and the main body side coupling portion 124 in the state where the main body side coupling portion 124, the cutter side coupling portion 166, and the lid side coupling portion 134 are overlapped in the front and back in order from the front. The welded portion 124c and the front surface of the cutter-side coupling portion 166 are flush with each other, and the rear surface of the cutter-side coupling portion 166 and the lid-side welded portion 134c of the lid-side coupling portion 134 are flush with each other. , 166, and 134 are integrally welded and fixed by welding means described in detail later.

[Operation of main control board case unit]
Next, an operation when the substrate case 110 is closed in the sealing structure configured as described above will be described. 8 is a perspective view showing a state before the seal seal 150 is attached to the case body 120, FIG. 9 is a perspective view showing a state before the seal seal cutter 160 is attached to the case body 120, and FIG. 11 is a perspective view showing a state before the case lid 130 is attached to the case body 120, FIG. 11A is a perspective view of the sealing structure in which the case lid 130 is superimposed on the case body 120, and FIG. FIG. 12A is a perspective view of the main control board case unit 100 in a state in which the case lid 130 is closed and attached to the case main body 120 from the rear side. FIG. 12B is a perspective view of the main control board case unit 100 in a state where the case lid 130 is attached to the case main body 120 as viewed from the front, and FIG. FIG. 13B is a cross-sectional view of the sealing structure with the case main body 120 closed and attached with the case lid 130, and FIG. 14. These are the schematic diagrams for demonstrating an ultrasonic welding process. 8 to 14, the main control board 41 and the caulking member 140 are not shown.

  First, when attaching the case lid 130 to the case main body 120, as shown in FIG. 8, the seal seal 150 is attached to the seal attaching surface 123c of the case main body 120 in a U-shape in advance. The sticking surface 123c of the pedestal portion 123a that is bent in a U-shape is formed in a size that matches the sealing sticker 150, and by sticking the sealing sticker 150 according to the sticking sticking surface 123c, The seal seal 150 covers the entire opening of the three slits 123d, and the antenna line 153 of the seal seal 150 is disposed so as to cross the three slits 123d.

  As shown in FIG. 9, the seal seal cutter 160 is positioned in front of the main body side seal portion 123 to which the seal seal 150 is attached, and the seal seal cutter 160 is moved forward while maintaining this posture. It is assembled to the main body side sealing portion 123 of the case main body 120. At this time, the engagement claw 164 of the seal seal cutter 160 and the engagement wall portion 123b of the main body side seal portion 123 are engaged, whereby the seal seal cutter 160 is temporarily fixed to the case main body 120. When the seal seal cutter 160 is assembled to the case main body 120 in this way, the cutter side coupling portion 166 of the seal seal cutter 160 and the main body side coupling portion 124 of the case main body 120 overlap in the front-rear direction. When the seal seal cutter 160 is assembled to the case main body 120 as described above, the destructive protrusion 162 of the seal seal cutter 160 and the seal seal 150 attached to the case main body 120 are displaced in the left-right direction. 162 does not contact the seal seal 150.

  Subsequently, the case lid 130 is attached to the case main body 120 by overlapping the case lid 130 at a position slightly shifted to the left with respect to the case main body 120 as shown in FIGS. This is performed by sliding the lid 130 in the right direction (closing direction).

  12, when the case lid 130 is closed and attached to the case main body 120, the main body side crimping portion 122 (main body side locking hole 122a) and the lid side crimping portion 132 (lid side locking hole 132a) In this state, the caulking member 140 is inserted so as to straddle the lid side lock hole 132a and the main body side lock hole 122a, so that the main body side caulking part 122 and the lid side caulking part are interposed via the lock member 140. 132 and the case lid 130 is attached to the case main body 120 so as not to be opened (unless the connecting portion 132b is cut off). At this time, in the sealing structure, the locking protrusion 163 of the sealing seal cutter 160 engages with the locking groove 133b of the lid side sealing portion 133, and the engaging claw 165 of the sealing seal cutter 160 is the locking side of the lid side sealing portion 133. Engaging with the engaging arm 133c, the seal seal cutter 160 and the case lid 130 are connected.

  At this time, as shown in FIG. 13, the main body side coupling portion 124 and the cutter side coupling portion 166 are integrally received in the receiving space 134 a of the lid side coupling portion 134, and the main body side coupling portion 124, the cutter side coupling portion 166 and the lid side coupling part 134 overlap in the front-rear direction. In this superposed state, the three coupling parts of the main body side coupling part 124, the cutter side coupling part 166, and the lid side coupling part 134 are ultrasonically welded. In the ultrasonic welding, as shown in FIG. 14, by applying pressure simultaneously to the three coupling portions 124, 134, and 166 in the front and rear directions simultaneously with ultrasonic vibration, the coupling portions 124, 134, and 166 are melted. Join. In addition, in FIG. 14, although the case where three coupling | bond parts are welded simultaneously is illustrated, it is not limited to this, The group of the main body side coupling | bond part 124 and the cutter side coupling | bond part 166, and the lid | cover side coupling | bond part 134 And the set of cutter side coupling portions 166 may be welded separately.

  Thus, when the substrate case 110 is held in the closed state, it is difficult to access the main control substrate 41 accommodated in the substrate case 110 from the outside. Here, as described above, the seal seal 150 is mounted with the IC tag 152 and the antenna line 153, and is in a state of being held inside the substrate case 110, and various information stored in the IC tag 152 ( For example, information regarding pachinko gaming machines PM, identification information of the main control board 41, and the like) can be read from the outside by a reader without opening the board case 110.

  Further, when the substrate case 110 is held in a closed state and the main body side coupling portion 124, the cutter side coupling portion 166, and the lid side coupling portion 134 are welded and coupled, the thin plate-shaped main body side coupling portion 124 and the cutter side coupling portion are used. Since 166 is received and covered by the container-like lid-side coupling part 134, it is difficult to insert a tool such as a screwdriver between the coupling parts and peel off the welding between the coupling parts.

  Next, the operation when the substrate case 110 is opened in the sealing structure according to the present embodiment will be described. Here, FIG. 15A is a perspective view of the main control board case unit 100 as viewed from the back side, and FIG. 15B is a view when the fracture portion 124a of the case main body 120 is broken and the main body side weld portion 124c is separated. FIG. 16 is a perspective view showing a state in which the case lid 130 is slid in the opening direction with respect to the case body 120, and FIG. 17A shows the case lid 130 opened with respect to the case body 120. FIG. 17B is a cross-sectional view of the sealing structure in a state in which the case lid 130 is slid in the opening direction with respect to the case main body 120, and FIG. 18 is the case main body. FIG. 6 is a perspective view showing a state in which a case lid 130 is opened with respect to 120. 15 to 18, the main control board 41 and the caulking member 140 are not shown.

  First, in order to open the substrate case 110, the connecting portion 132 b that connects the lid-side caulking portion 132 and the lid-side base portion 131 in the caulking structure is cut using a tool such as a nipper, and the main body is interposed via the caulking member 140. The lid side crimping part 132 in a state of being engaged and connected to the side crimping part 122 is separated from the case lid 130. Further, as shown in FIG. 15, the breaking portion 124 a that partitions and forms the main body side welding portion 124 c in the sealing structure is broken along the slit 124 b by using a tool such as a nipper, and the cutter side coupling portion 166 and the lid side coupling portion. The main body side coupling portion 124c welded to the 134c is separated from the case main body 120. As a result, the connection between the case main body 120 and the case lid 130 is cut off, and the substrate case 110 can be opened.

  In a state before the case lid 130 is opened with respect to the case main body 120, as shown in FIG. 13 and the like, the fracture protrusion 162 of the seal seal cutter 160 is not in contact with the seal seal 150 and is in close proximity with a predetermined distance. doing. As described above, since the case lid 130 and the seal seal cutter 160 are integrally coupled (engaged and welded), when the case lid 130 is slid in the left direction (opening direction) from this state, The seal seal cutter 160 moves together with the lid 130 in the opening direction. Further, as described above, since the fracture portion 124a of the main body side coupling portion 124 is broken and the main body side welding portion 124c is separated from the case main body 120, the main body side welding portion 124c of the main body side coupling portion 124 is the case. It separates from the main body 120 and moves together with the case lid 130 and the seal seal cutter 160. On the other hand, an outer portion 124d (see FIG. 18) of the main body side coupling portion 124 from the destruction portion 124a remains in the case main body 120 as a trace of the main body side coupling portion 124 being broken.

  Here, the slit 123d formed in the main body side sealing portion 123 of the case main body 120 is recessed corresponding to the movement trajectory of the breaking projection 162 of the sealing seal cutter 160, and is sealed so as to cross the slit 123d. Since 150 is provided on the sticking surface 123c, when the seal seal cutter 160 is slid together with the case lid 130, the destruction protrusion 162 contacts the seal seal 150 and breaks the seal seal 150 along the slide direction. However, it passes through the slit 123d. If the seal seal 150 is torn in this way, the antenna wire 153 can be destroyed even if the IC tag 152 itself cannot be destroyed, and various information stored in the IC tag 152 becomes substantially unreadable. As a result, traces of unauthorized access can be left, and the seal seal 150 can be destroyed (cannot be reused) to the extent that it cannot be regenerated.

  If the seal seal cutter 160 is slid in the opening direction together with the case lid 130, the breaking projection 162 completely breaks the seal seal 150 and escapes from the open end of the slit 123d, and the case body 120 slides on the body side. When the engaging portion 121c reaches a predetermined position where it is removed from the lid-side groove 131b of the case lid 130, the case lid 130 is removed from the case main body 120 by moving the case lid 130 rearward.

  The sealed case cutter 130 is welded and integrally joined to the case lid 130 thus removed, and it is difficult to separate the joined case lid 130 and the sealed seal cutter 160 from each other without damaging them. Therefore, the case lid 130 and the seal seal cutter 160 can be made unusable in an intact state.

  As described above, in the main control board case unit 100 according to the present embodiment, when the board case 110 is opened, the case main body 120 is left with a trace due to the fracture portion 124a of the main body side coupling portion 124 being broken and sealed. The seal 150 remains in a state of being cut by the seal seal cutter 160, and the case lid 130 and the seal seal cutter 160 are in a state where they cannot be separated from each other by welding (the weld marks remain even if they are forcibly separated). Any of the case main body 120, the case lid 130, the seal seal cutter 160, and the seal seal 150, which are components of the main control board case unit 100, is difficult to reuse without leaving any traces. It is possible to surely prevent an illegal assembly action called “Nikoichi” (two 1). Therefore, according to this embodiment, there is an effect that it is possible to contribute to prevention and early detection of fraud.

  Further, in the main control board case unit 100 according to the present embodiment, when the sealing seal cutter 130 is slid in the left-right direction (the closing direction and the opening direction) to be attached to and detached from the main body side sealing portion 123, the main body side sealing portion The seal seal 150 attached to 123 is broken. Therefore, when reusing the substrate case 110 once opened as described above, a counterfeit product in which the seal seal 150 is copied is used, and the case lid 130 and the seal seal cutter 160 are not separated from each other, and the case is in a combined state (welded state). When trying to reassemble the main body 120, when the case lid 130 and the sealing seal cutter 160 are slid in the closing direction with respect to the case main body 120, the sealing seal cutter 160 destroys the counterfeit product. Since the traces remain, the case lid 130 and the seal seal cutter 160 cannot be assembled together without being separated from each other, and an unauthorized assembling operation called Nikoichi (two 1) is more reliably performed. It is possible to prevent.

  In the main control board case unit 100 according to the present embodiment, the main body side coupling portion 124 and the cutter side coupling portion 166 are each formed in a rectangular thin plate shape, and the lid side coupling portion 134 is on the main body side in the closed state of the substrate case 110. It is formed in a rectangular box shape that opens to the side opposite to the coupling portion 124 and the cutter side coupling portion 166 and can receive these coupling portions, so that the gap between the lid side coupling portion 134 and the cutter coupling portion 166 (or The case body 120, the case lid 130, and the sealing seal can be easily separated by inserting a tool such as a screwdriver (between the main body side coupling portion 124 and the cutter side coupling portion 166). It becomes possible to more strictly prevent unauthorized reuse of the cutter 160.

  In addition, this invention is not limited to the said embodiment, If it is a range which does not deviate from the summary of this invention, it can improve suitably.

  Further, in the above-described embodiment, the main body side coupling portion 124, the lid side coupling portion 134, and the cutter side coupling portion 166 are welded and joined after the substrate case 110 is in a closed state, but the present invention is not limited thereto. First, after attaching the seal seal cutter 160 to the case main body 120, the main body side coupling portion 124 and the cutter side coupling portion 166 are welded and bonded, and then the case lid 130 is closed to the case main body 120. After the attachment, the lid side coupling portion 134 and the cutter side coupling portion 166 may be welded and joined, and the order in which the three coupling portions 124, 134, and 166 are joined can be appropriately changed.
