Description

  The present invention provides a circuit board protective case that can reliably detect and effectively prevent illegal acts when ROMs mounted in various gaming machines such as pachinko gaming machines and slot machines are illegally replaced, and It relates to gaming machines.

By illegally replacing the ROM mounted on various gaming machines such as pachinko machines and slot machines, a so-called Goto teacher conducts a fraudulent act to conveniently advance the game contents to the player and acquire a ball. The method has become more sophisticated.
There is a high possibility that the illegal replacement of the ROM is performed before or after the game machine shipped from the factory is installed in the game hall.
As a countermeasure against such an illegal act, Patent Document 1 discloses a trace of the case where the coupling means is destroyed by coupling the case body surrounding the ROM on the control board and the cover body by a non-separable coupling means. There are proposals for technologies that ensure that these remain.
However, as the tricks of fraudsters become more sophisticated, there is a possibility that new coupling means may be assembled so that no evidence remains after the coupling means is destroyed and the ROM is replaced.
Patent Document 2 discloses an apparatus configuration for preventing fraud, but has the same drawbacks as in Patent Document 1.

In order to deal with such problems, the board protective case is sealed with a seal sticker, but after cutting the seal sticker with a cutter, the board protective case is opened and the ROM is replaced. When the cut surface of the seal seal is repaired after the substrate protection case is closed, there are many cases in which the presence or absence of the cut portion cannot be visually determined. In order to cope with such a problem, a seal seal incorporating an RFID has been used.
That is, Patent Document 3 discloses a substrate protective case by bonding a seal seal incorporating an RFID (non-contact type storage medium) storing identification information across a case main body and a case lid constituting the substrate protective case. A technique is disclosed in which when RFID is illegally opened, RFID is broken or disconnected, making it impossible to read identification information. According to this, when the identification information stored in the RFID cannot be read using the reading device, it is possible to know that the substrate protection case has been illegally opened.
Patent Documents 4 and 5 also disclose similar fraud detection techniques using IC tags and tape-type inlets.

13 and 14 are a perspective view and an exploded perspective view showing a configuration of a conventional substrate protection case. A substrate protective case 100 that accommodates a control substrate 120 therein has a configuration in which a case main body 101 and a case lid 102 are joined. A sealing seal 110 is bonded to the butted portion 103 between the case main body and the case lid located at one end of the substrate protection case 100 across the both.
The seal seal 110 includes an adhesive sheet 111 made of a material that can be easily broken, such as paper having an adhesive layer on one surface, and an RFID (for example, an IC tag) 112 fixed to the adhesive sheet. The RFID 112 includes a chip 113 including a power generation circuit, a modulation / demodulation circuit, a storage circuit, and a control circuit, two conductor patterns 114 extending in the opposite direction from the chip, and an antenna unit 115 connected to the tip of each conductor pattern 114, have. When a reading electromagnetic wave is irradiated from a reading device (not shown) toward the RFID 112, a power generation circuit in the chip generates an electromotive force by an electromagnetic induction action, and is stored in the storage circuit by a control circuit that operates by the electromotive force. The identification information can be read by reading the identification information and transmitting it from the antenna to the reading device.
The conductor pattern 114 constituting the RFID extends in the diagonal direction of the adhesive sheet 111, and the substrate protective case is illegally opened by adhering a seal seal so that the conductor pattern 114 intersects the abutting portion 103. In some cases, part of the conductor pattern may be disconnected, making it impossible to read stored information.

However, according to an experiment by the present applicant, even when the sealing pattern 110 is broken when the substrate protection case is opened and the conductor pattern constituting the RFID 112 is broken only at one place, when the substrate protection case is reclosed, It was possible to restore the continuity between the broken parts by repairing the state of the seal.
In particular, when the conductor pattern is cut at one place in the process of cutting the sealing seal 110 with a cutter along the linearly extending abutting portion 103, it is relatively easy to re-conduct the conductor pattern by a subsequent repair operation. Become.

It has an adhesive sheet that seals the butting part, and the shape and size of the butting part are configured to break the sealing seal by sliding each case, The serial tapered surface, wherein the broken edge of the adhesive sheet is adhered folded back.
One edge (movable side) of each case piece constituting the circuit board protective case is retracted in a taper shape to the inside of the front end surface of each case piece, so that the edge of the seal seal that breaks when the case piece is opened The taper surface can be bonded. For this reason, when the substrate protective case which is sealed by a sealing mark seal is broken is sealed seal by which is illegally opened, it can also be difficult as trying to repair the seal seal.
In addition, since the shape of the abutting portion between the edges of each case piece constituting the substrate protection case is configured so that the seal seal is broken at a plurality of positions when each case piece is opened, the substrate protection case sealed by the seal seal If the seal seal is broken or disconnected due to the illegal opening of the seal seal, it can be difficult to repair the seal seal. In particular, one of the edges of the case piece (movable side) is retracted in a taper shape to the inside of the tip surface of each case piece, so the edge of the seal seal that breaks when the case piece is opened is adhered to this tapered surface. It becomes possible to make it.

The butt portion extends in a direction intersecting with the extending direction of the conductor pattern.
According to a fourth aspect of the present invention , the seal seal includes the adhesive sheet, an IC chip fixed to the adhesive sheet surface, and an RFID including a conductor pattern extending from the IC chip. The IC chip and the conductor pattern are configured such that the IC chip and the conductor pattern that form the sealing seal intersect at a plurality of locations, and the IC chip and the conductor pattern are opened to the intersection when the cases are opened. The butt portion extends in the same direction as the extending direction of the conductor pattern.
In the invention of claim 5 , a concave notch is provided at an edge of one case piece forming the abutting portion, and a convex piece fitted into the concave notch is provided at an edge of the other case piece. The sealing seal adhered to the convex piece is broken when each case piece is opened.

According to a sixth aspect of the present invention , the abutting portion includes an elastic protruding piece in which a part of an edge of one case piece is elastically protruded outward from an edge of the other case piece, The protruding piece is configured to be retractable to a non-projecting position.

Is folded and adhered to the tapered edge (tapered surface) of the case piece, so that it is included in the sealing seal when the substrate protective case sealed by the sealing seal incorporating RFID is illegally opened. When the RFID to be broken is broken or disconnected, it is possible to make it difficult to restore the sealing function by restoring the sealing seal.

Hereinafter, the present invention will be described in detail with reference to embodiments shown in the drawings.
FIG. 1 is a perspective view showing an external configuration of a substrate protection case according to the present invention, FIG. 2 is an exploded perspective view thereof, and FIG. 3 is a main part configuration diagram for explaining an assembly procedure of both case pieces. 4 is a view showing a procedure for sliding the upper case from the lower case, and FIG. 5 is an explanatory view showing a state before the sealing seal is adhered to the sealing end, and FIGS. 6 (a) and 6 (b). ) Is an explanatory view of a procedure for breaking the bonded seal seal, and a diagram showing the broken seal seal.
The board protection case 1 is assembled on the back side of a gaming machine such as a pachinko gaming machine with a control board (printed board) B on which electronic components such as a ROM are mounted therein.
The substrate protective case 1 is composed of two transparent resin case pieces (a lower case piece 2 and an upper case piece 10) that are housed inside with a control board (printed board) 120 having a ROM mounted therebetween. Has been. The two case pieces 2 and 10 are assembled so as to face both surfaces of the control board, and are configured to open and close by sliding in a direction parallel to the control board surface indicated by arrows.

Reference numeral 2a denotes a long hole-like slide locking portion provided on the lower case piece 2 side, and an engagement protrusion provided on the upper case piece 10 inside the long hole via a notch provided in the slide locking portion. By engaging 10a, the upper case piece 10 is slidable in the longitudinal direction with respect to the lower case piece 2, and can be attached / detached (opened / closed) by sliding.
Reference numeral 70 denotes a connecting member for attaching the board protection case 1 to a gaming machine side holding portion provided on the back side of the gaming machine, and the hook portion 71 provided on the connecting member 70 is connected to the gaming machine side holding portion. The substrate protection case 1 can be pivotally supported so as to be rotatable in the vertical direction around the shaft portion 75. Since the lower case piece 2 of the board protection case 1 is held by the connecting member 70, the board protection case 1 can be rotated in the vertical direction around the shaft portion 75 on the gaming machine side.

The board protective case 1 containing the control board B is assembled with the lower case piece 2 attached to the back side of a game board such as a pachinko game machine via the connecting member 70, so that the upper case from the back side of the game board. The electronic component mounted on the internal control board surface can be visually recognized through the piece 10. Further, the inside of the substrate protection case can be confirmed from the bottom surface of the transparent lower case piece 2 by rotating the substrate protection case 1 upward about the shaft provided on the upper part of the connecting member.
In this example, the sliding engagement member 10 is provided with an engaging protrusion 10 a provided on the upper case piece 10 in a state where the control board B is disposed in an internal recess of the lower case piece 2 fixed to the connecting member 70. The upper case piece 10 is put on the lower case piece 2 by fitting it to the stop portion 2a (FIG. 3), and then the upper case piece 10 is slid in the closing direction indicated by the arrow in FIG. They can be combined in the closed state (state shown in FIG. 1). On the contrary, when the substrate protection case 1 in the closed state in FIG. 1 is shifted to the open state, a slide in which the engagement protrusion 10a provided on the upper case piece 10 is provided on the lower case piece 2 as shown in FIG. What is necessary is just to make an engagement protrusion remove | separate from a notch after making it slide to the open direction shown by the arrow along the latching | locking part 2a.

Sealing pieces 3 and 11 project from one end portions of the lower case piece 2 and the upper case piece 10, and a sealing end portion 20 is formed by abutting both the sealing pieces 3 and 11. Also, a butt portion 21 is formed at the interface where the end edges 3a and 11a of both seal pieces are butt.
When the substrate protective case 1 is in the closed state as shown in FIG. 1, the sealing portion 30 cannot be opened without damaging the sealing seal 30 by adhering the sealing seal 30 so as to straddle both the sealing pieces 3 and 11. It is configured as follows.
The sealing seal 30 includes an adhesive sheet 31 made of a material that is easily broken, such as paper having an adhesive layer on one surface, and an RFID (for example, an identification means using a non-contact type radio wave such as an IC tag) fixed to one surface of the adhesive sheet 31 35). The RFID 35 includes a chip 36 including a power generation circuit, a modulation / demodulation circuit, a storage circuit, and a control circuit, two conductor patterns 37 extending in the opposite direction from the chip 36, and an antenna unit 38 connected to the tip of each conductor pattern 37. And have. In the sealing seal 30 of this example, a chip 36 is disposed at a substantially central portion of a rectangular adhesive sheet 31 and each conductor pattern 37 is drawn from the chip 36 in a substantially diagonal direction.
When a reading electromagnetic wave is irradiated toward the RFID 35 from a reading device (not shown), the antenna unit 38 receives the electromagnetic wave and supplies the electromagnetic wave to the chip 36 via the conductor pattern 37. With this electromagnetic wave, the power generation circuit in the chip 36 generates an electromotive force due to the electromagnetic induction effect, and the identification information stored in the storage circuit is read by the control circuit operated by this electromotive force and transmitted from the antenna unit to the reading device. Thus, the identification information is read.

The linear conductor pattern 37 constituting the RFID extends in a substantially diagonal direction of the adhesive sheet 31, and a sealing seal 30 is adhered so that the conductor pattern 37 intersects the abutting portion 21, whereby the substrate protective case is When the circuit is opened improperly, a part of the conductor pattern may be disconnected, making it impossible to read stored information.
That is, when the upper case piece 10 is slid in the opening direction indicated by the arrow in FIG. 4 with respect to the lower case piece 2 in order to open the substrate protective case 1, the butting portion 21 is opened (positioned in the sliding direction). By shifting, part of the RFID 35 (chip part 36 and conductor pattern 37) together with the adhesive sheet 31 is broken (disconnected), and the communication function of the RFID is lost. If the RFID communication function is lost, even if electromagnetic waves are supplied from the reader, the RFID will not operate, and the stored identification information cannot be read, so that the circuit board protective case has been opened illegally. be able to.
However, in actuality, when only one of the two conductor patterns 37 is disconnected when the substrate protective case 1 is opened, the case pieces 2 and 10 are returned to the closed state and fractured. It has been found that by repairing the seal seal 30, the disconnected portion can be restored by reconnection to restore conduction (communication with the reading device).

Therefore, in the present invention, the shape of the abutting portion 21 is configured so that when the case pieces 2 and 10 are opened, the RFID is surely broken at a plurality of locations, for example, at least one location of the two conductor patterns 37.
That is, the abutting portion 21 provided in the substrate protection case 1 according to the present embodiment includes the first convex portion 3A and the first concave portion 3B formed on the edge 3a of the one case piece 2, and the first concave portion 3B. It includes a second concave portion 11A and a second convex portion 11B formed on the edge 11a of the other case piece 10 so as to be fitted to the convex portion 3A and the first concave portion 3B, respectively. The outer peripheral edge of each convex part 3A, 11B and the inner peripheral edge of each concave part 3B, 11A are set in shape and size so as to intersect the chip 36 and the conductor pattern 37 constituting the RFID.
While the outer surface of each convex part 3A, 11B and the outer surface of each concave part 3B, 11A are bonded to the adhesive sheet 31 with sufficient adhesive force, the butt part (convex part and concave part) 21 is Since the RFID case 35 intersects with the RFID 35 at least at two locations, the RFID 35 is broken along with the adhesive sheet 31 at a plurality of locations when the movable case 10 is slid relative to the stationary case 2 (see FIG. 6 (b)).
In addition, by setting the adhesive force between the adhesive sheet 31 and the outer side surfaces (tip surfaces) of the sealing pieces 3 and 11 to be sufficiently strong, the adhesive sheet 31 extends along the periphery of the convex portion and the concave portion. When the conductor pattern is cut, the conductor pattern at the cutting position is also easily cut with good responsiveness.
Furthermore, in the substrate protection case of the present invention, as shown in FIG. 7 (AA cross-sectional view in FIG. 5), the tip edge 10A of the upper case piece 10 (sealing piece 11) constituting the butting portion 21 is the tip. By making the tapered surface retracted inward from the surface 10B, the edge 30a of the broken seal seal 30 is folded and bonded to the tapered surface 10A. By forming the tip edge 10A of the upper case piece 10 (sealing piece 11) as a tapered surface that is retracted inward from the tip face 10B, a recess (sealing sheet non-adhesive portion) is formed in at least a part of the abutting portion 21. The

FIG. 7A is a cross-sectional view showing a state in which a sealing seal is bonded to the front end surfaces of both sealing pieces 3 and 11 in a closed state, and when the upper case piece 10 is slid in the opening direction from this state, As shown in (b), the seal seal portion 30A adhered to the upper case piece 10 side is broken and separated from the seal seal portion 30B adhered to the lower case 2 side, and the edge 30a of the seal seal portion 30A is separated. The adhesive surface is folded back at the corner between the taper surface 10A and the tip surface 10B and bonded to the taper surface 10A.
Thus, even when both case pieces are closed again as shown in FIG. 7C, the edge 30a of the seal seal is adhered to the tapered surface 10A. It becomes difficult. In particular, since the end edge of the seal seal cut by the abutting portion composed of the convex portion and the concave portion is in a state of being bonded to the tapered surface 10A over the entire length, the edge 30a of the seal seal portion 30A bonded to the tapered surface is provided. It is extremely difficult to peel off and reconnect with the edge of the other seal seal portion 30B. For this reason, it becomes extremely difficult to re-connect between the cut ends of the conductor pattern 37 located at the respective edges of the both sealed seal portions 30A and 30B. In particular, fraudulent acts such as ROM replacement performed by opening the board protection case placed on the back side of gaming machines installed in amusement halls are often carried out during amusement park operations. There is only a short time available. For this reason, in a short time, after breaking the seal and opening the substrate protective case and replacing the ROM, the substrate protective case is closed again, and the edge of the seal seal bonded to the tapered surface 10A is peeled off to remove the RFID. It is almost impossible to repair.
In addition, the angle of the corner | angular part between 10 A of taper surfaces and the front end surface 10B should just be an obtuse angle. Further, the tapered surface 10A does not have to be a strictly flat surface, and may be a curved surface.
In addition, the structure which makes the front-end edge of an upper case piece a taper surface is applicable also to the board | substrate protective case of the type in which abutting part extends linearly as shown in FIG.13 and FIG.14.
That is, FIG. 8 is a cross-sectional view showing the configuration of the main part in the case where the tip edge of the upper case 10 of the substrate protection case having a linear butting portion is a tapered surface 10A.

FIG. 8A is a cross-sectional view showing a state in which a sealing seal is adhered to the front end surfaces of both sealing pieces 3 and 11 in a closed state, and when the upper case piece 10 is slid in the opening direction from this state, As shown in (b), the seal seal portion 30A adhered to the upper case piece 10 side is broken and separated from the seal seal portion 30B adhered to the lower case 2 side, and the edge 30a of the seal seal portion 30A is separated. Is folded at the corner between the taper surface 10A and the tip surface 10B and adhered to the taper surface 10A.
For this reason, it becomes difficult to reconnect between the cut conductor patterns as in the case of FIG.
In addition, although the front shape of the butt | matching part 21 illustrated in FIG. 1 thru | or FIG. 6 has each convex part 3A, 11B and recessed part 3B, 11A in a triangle shape, a butt | matching part is a conductor of RFID on an adhesive sheet As long as it is configured in a non-linear shape so as to intersect the pattern 37 at two or more places, as shown in FIGS. 9A and 9B, a rectangular shape (including a trapezoidal shape), a substantially arc shape (sine curve) Any shape can be selected.

Further, the convex portions 3A and 11B and the concave portions 3B and 11A do not need to be formed over the entire length of the abutting portion 21, and need only be provided corresponding to the portion where the conductor pattern 37 to be broken exists.
In addition, since the seal seal is usually bonded manually, there is a possibility that the bonding position and bonding direction may not be constant. However, in such a case, each conductor pattern is more than one place (two places in total) Above) Select the vertical width, horizontal width, and number of protrusions and recesses so that they can be cut. In addition, the outer periphery of the convex portion and the concave portion when the two case pieces 2 and 10 are slid by keeping the gap between the peripheral portions of the convex portion and the concave portion, which are fitted to each other, without causing a close contact therebetween. It becomes easy to cut the seal seal along the contour.
Note that if the RFID 35 can be disconnected at two or more sites, it will be more difficult to restore continuity by repair work by an unauthorized person.

Moreover, in the said embodiment, although convex part 3A, 11B and recessed part 3B, 11A are located only in the front end surface of each sealing piece 3, 11, respectively, the other orthogonal to the front end surface of each sealing piece 3, 11 You may comprise so that a recessed part and a convex part may be extended to the surface (surface parallel to a sliding direction) 3b, 11b. In this case, it is possible to cut the conductor pattern adhered on the other surfaces 3b and 11b when the substrate protection case is illegally opened, and the communication function of the RFID can be more reliably lost.
Further, the shape of the abutting portion 21 according to the above embodiment extends in a direction (surface direction of the substrate protection case) intersecting with a diagonal direction in which the conductor pattern 37 constituting the RFID 35 extends. The configuration of the butting portion 21 may extend in the same direction as the extending direction of the conductor pattern (including the chip 36) as in the configuration example shown in FIG. Thus, by making the extending direction of the conductor pattern coincide with the extending direction of the abutting portion, the convex portions 3A and 11B and the concave portions 3B and 11A constituting the abutting portion are more reliably connected to each conductor pattern 37 and one or more places. It can be crossed at (total or more), and reliable cutting is possible when the case piece slides.
Also in the embodiment of FIGS. 9 and 10, it is preferable that the tip edge of the upper case 10 constituting the butting portion 21 of the substrate protection case is a tapered surface 10 </ b> A.

Next, FIGS. 11A, 11 </ b> B, and 11 </ b> C are explanatory views showing the main configuration of a substrate protection case according to another embodiment of the present invention.
A characteristic configuration of this embodiment is that one case piece forming the abutting portion 21, in this example, a concave notch 40 is provided at the edge of the sealing piece 11 of the upper case piece 10, and the other case piece 2 A convex piece 41 is provided on the edge of the sealing piece 3 to be fitted in the concave notch 40, and the local part of the RFID 35 on the sealing seal 30 adhered to the outer surface of the convex piece 41 when the case pieces 2 and 10 are opened. Is configured to be destroyed.
In this example, a concave notch 40 is provided in the center of the edge of the upper case piece 10, and a convex piece 41 that fits in the concave notch 40 is provided in the center of the edge of the lower case piece 2. The chip 36 on the seal seal adhered to the outer surface of the convex piece 41 is forcibly separated from the two conductor patterns 37 when the case piece is opened. For this reason, it is almost impossible to restore the conduction between the chip 36 and the conductor pattern 37 even if the case piece that has been opened improperly is closed again to restore the sealing seal. Furthermore, the communication function of RFID can be more reliably lost by using the cutting of the conductor pattern by the convex part and the concave part in the above embodiment together.
In addition, the shape of the notch 40 and the convex piece 41 may be an arc shape as illustrated, or may be a triangle, a rectangle, or other shapes.

Thus, by providing the concave / convex fitting portion including the notch 40 and the convex piece 41 in one place, it becomes possible to concentrate the cutting force applied to the sealing seal 30 when the case piece is opened in one place. In addition, stable cutting can be realized.
Further, as shown in FIGS. 11B and 11C, the tip edge of the upper case 10 of the substrate protection case is formed into a tapered surface 10A, so that the RFID is broken in a non-reproducible state as in the embodiment of FIG. Effect can be obtained.
That is, FIGS. 11B and 11C are cross-sectional views taken along the lines CC and DD in FIG. 11A, respectively, and the tip end edge of the movable case piece, that is, the upper case piece 10 is formed as a tapered surface 10A. When the upper case 10 is slid in the opening direction, the broken edge of the seal seal 30 can be adhered to the tapered surface. For this reason, it becomes extremely difficult to reproduce the cut RFID.

Next, FIGS. 12A to 12D are explanatory views showing the main configuration (cross-section of the sealing end) of a substrate protection case according to another embodiment of the present invention.
The sealing end portion 20 according to this embodiment is such that the abutting portion 21 has a part of the edge of the sealing piece 11 on the upper case piece side outside the edge of the sealing piece 3 on the lower case side (the upper case piece at the time of opening). The elastic protruding piece 55 is elastically protruded in the direction of movement of the elastic protruding piece 55, and the elastic protruding piece 55 is configured to be retractable to the non-projecting position shown in FIG.
In a state before the sealing seal 30 is bonded to the sealing end portion 20, as shown in FIG. 12 (a), the elastic protruding piece 55 protrudes outward (moving direction of the upper case). It is possible to bond the seal seal 30 to the seal end portion after the inner surface is elastically deformed to flatten the front surface of the seal end portion ((b)).
In the state where the elastic protruding piece 55 is pressed by the seal seal 30 as shown in FIG. 12B, the seal seal will not break, but in the direction of the arrow to open the upper case piece 10 with respect to the lower case piece 2. When the upper case piece 10 is slid, the original restoring force of the elastic protruding piece 55 is applied, so that the local portion of the seal seal 30 can be more reliably cut.

Also in the present embodiment, as in the case of the embodiment of FIG. 7, the tip edge of the upper case 10 of the substrate protection case is formed as the tapered surface 10 </ b> A, so that the effect of breaking the RFID in an unreproducible state can be obtained. .
The tip end edge of the movable case piece, that is, the upper case piece 10 (the tip end edge of the elastic protruding piece 55) is a tapered surface 10A, so that the end of the seal seal 30 that is broken when the upper case 10 is slid in the opening direction. The edge 30a can be adhered to the tapered surface 10A. For this reason, even if an unauthorized person tries to repair the sealing seal 30 after reclosing both the case pieces 2 and 10, it becomes extremely difficult to regenerate the cut RFID.
In each of the above embodiments, the case where the sealing seal 30 is bonded across the sealing pieces 3 and 11 protruding from the case pieces 2 and 10 has been described. However, the configuration of the butting portion according to the present invention is a protruding sealing end portion. The present invention is not limited to 20, and can be applied to the entire butt portion formed by the edges of the case pieces 2 and 10.

As described above, according to the present invention, the shape 21 of the abutting portions of the edge portions of the case pieces 2 and 10 constituting the substrate protection case 1 is configured such that the RFID 35 is broken at a plurality of locations when the case pieces are opened. Therefore, when the RFID contained in the seal seal is broken or disconnected due to the unauthorized opening of the substrate protective case sealed by the seal seal 30 incorporating the RFID, the RFID can be restored no matter how the seal is repaired. Recovery of the communication function can be made difficult.
That is, when the abutting portion is only a straight line as in the prior art, the RFID could only be cut at about one place. However, since the abutting portion 21 is configured so as to intersect with the RFID at a plurality of places, It becomes possible to cut.
Furthermore, in the present invention, the shape of the abutting portion between the end edges of each case piece constituting the substrate protection case is such that when the seal seal is broken by opening each case piece, the broken edge 30a of the seal seal is folded back. In this case, it is configured to adhere to the tapered edge (tapered surface) 10A of the case piece, so that the RFID included in the seal seal is opened by unauthorized opening of the substrate protection case sealed by the seal seal incorporating the RFID. When the cable breaks or breaks, it is possible to make it difficult to restore the sealing function by restoring the sealed seal.
