  FIG. 30 is an explanatory diagram showing an outline of a conventional first control board case. FIG. 31 is an explanatory diagram showing an outline of a conventional second control board case.

As shown in FIG. 30, a conventional first control board case is provided with a board housing case C for housing a control board B for controlling a game, and a case body CB and a case of the board housing case C. The IC chip sealing seal S is bonded to the boundary of the lid CC across the case main body CB and the case lid CC, and the data of the IC chip sealing seal S is read by the IC reading checker R.
Furthermore, in order to tamper with the control board B accommodated in the substrate accommodation case C by sneaking into a pachinko parlor at midnight or the like, the case cover CC of the substrate accommodation case C is forcibly opened, or the IC chip sealing seal S is removed. When an unreasonable force is applied to the IC chip sealing seal S so as to be peeled off, the built-in IC chip is broken.

  In the conventional first control board case having the above-described configuration, the IC chip is damaged when an unauthorized person attempts to tamper with the control board and improperly crafts the board housing case. Reading was impossible, and this checked the presence or absence of falsification of the control board.

  In the conventional second control board case, as shown in FIG. 31, the main board B is accommodated in a board box composed of a box base BB and a box cover BC, and the box base BB and the box cover BC are respectively The pasting portions SB1 and SB2 were formed, and the seal seal S was pasted so as to straddle both pasting portions SB1 and SB2. Furthermore, the sealing seal S is formed with a large number of antenna cuts arranged at equal intervals along the longitudinal direction of the antenna portion.

  In the conventional second control board case having the above-described configuration, the stress associated with the force for peeling off the sealing seal S is concentrated on the end of the antenna notch located around the antenna part, so that the antenna notch passes through the antenna notch. Since the antenna part is destroyed and the antenna part is divided accordingly, the fraudster accesses the board storage case and the sealing sticker in an attempt to tamper with the control board as in the case of the first conventional control board case. At that time, the seal seal is broken and cannot be read by the scanner, so that the presence or absence of falsification of the control board is checked.

  However, as described above, the second engagement recesses 322a and 322b are formed by the slide grooves extending in the vertical direction with the end portions opened upward in FIG. Since the lower surface in FIG. 12 is an open surface, the protective case 4 is removed upward along the slide grooves of the second engaging recesses 322a and 322b as shown by arrows in FIG. Is possible.

  The IC tag seal cutting means 7 formed on the inner surface 400c of the front end surface 40c of the protective case 4 when moving from the first engagement recesses 321a and 321b to the second engagement recesses 322a and 322b. The blade part 70 to be configured cuts the IC chip 63 of the IC tag seal 6. At this time, since the IC tag seal sticking portion 302 is formed with the cutting means recess 304, the cutting portion 70 that cuts and penetrates the IC tag seal 6 moves along with the pressing operation of the protective case 4. 304 is invaded. Then, when the protective case 4 is removed upward along the slide grooves of the second engaging recesses 322a and 322b, the blade portion 70 is stuck on the side surface 302f of the IC tag seal sticking portion 302. The other part of the IC tag seal 6 is cut so as to be peeled off.

  The control board case of the first embodiment having the above-described operation is the main control board case 3 in which the main control board 5 is housed, and IC tag seal attaching portions 302 and 312 are formed in the respective cases and can be separated from each other. An IC tag seal 6 including an IC chip 63 and an antenna portion 62, and an IC tag seal attaching portion 302, 312 and a front case 30, a rear case 31, and the IC tag seal attaching portions 302, 312. Protective case for protecting the IC tag seal 6 by engaging the engaging claw portions 422a and 422b to the first engaging recesses 321a and 321b formed at the locking position and surrounding the IC tag seal attaching portions 302 and 312. 4 and an IC which is disposed in a part of the protective case 4 and cuts the IC tag seal 6 when the protective case 4 is removed. The IC tag seal cutting means 7 when the protective case 4 is pushed into the locking position of the IC tag seal sticking portions 302 and 312 in order to remove the protective case 4. The protection that is configured to cut at least a part of the IC tag seal 6 and is engaged with the first engaging recesses 321a and 321b formed at the locking positions of the IC tag seal attaching portions 302 and 312. The engagement claw portions 422a and 422b of the case 4 are configured to move to the second engagement recesses 322a and 322b as removal positions where the protection case 4 can be removed when pushed in from the locking position. Therefore, the IC tag seal 6 is appropriately protected by a protective case 4 from an external impact or the like in a normal configuration with a simple configuration. Both when the IC tag seal 6 wherein the protective case is pushed is disconnected, an effect that can be accurately grasped that there is a possibility that fraud has been performed.

In addition, for example, when the antenna part of the IC tag seal is cut only at one place and then the cut surface is returned to its original position, the cut part of the antenna part may come into contact with the communication function between the IC chip and the antenna part. In some cases, the control board case of the first embodiment includes a memory in which the blade portion 70 of the IC tag seal cutting means 7 stores identification information of the IC tag seal 6 and the like. Since the IC chip 63 is reliably cut and destroyed, and the other part (including the antenna part) of the IC tag seal 6 is also peeled off in accordance with the extraction operation of the protective case 4, the communication function of the IC tag seal 6 is improved. It has the effect of being surely erased and making it impossible to return the cut surface cleanly.

  Further, in the control board case of the first embodiment, since the main control board case 3 is composed of a front case 30 and a rear case 31 that are separable from each other, the main control board case 3 is opened. In order to access the main control board 5 to be tampered with, it is necessary to remove the IC tag seal 6 attached so as to straddle the front case 30 and the rear case 31. In order to access the IC tag seal 6 In this case, removal by pushing in the protective case 4 that protects the IC tag seal 6 is indispensable, and when an unauthorized person is pushed to remove the protective case 4, the IC tag seal cutting means 7 is surely Since the IC tag seal 6 is cut and destroyed, there is an effect that a trace of fraud can be reliably left.

  In the control board case of the first embodiment, the IC tag seal 6 is cut by forming a cutting means recess 304 at a position corresponding to the blade portion 70 of the IC tag seal cutting means 7 of the IC tag seal attaching portions 302 and 312. Since the clearance space for the subsequent blade portion 70 is secured, the IC tag seal cutting means 7 can cut the IC tag seal 6 more reliably.

  Further, in the control board case of the first embodiment, since the members constituting the protective case 4 are made of a translucent material, the inside of the protective case 4 (for example, the IC tag seal 6 or the IC tag seal cutting means 7) It is possible to grasp the existence) from the outside, and to give the terrorist the fear of leaving the trace of the wrongdoing, which is used as a deterrent to prevent the wrongdoing.

  Further, the control board case of the first embodiment realizes the detection of fraud with a small number of parts because there are no additional parts by devising the shapes of the protective case 4 and the IC tag seal attaching portions 302, 312. As a result, space saving and low cost are realized.

As shown in FIGS. 13 to 20, the control board case of the second embodiment has a point that the protective case 4 is composed of a PUSH part 41 that is a movable part and a base member 42 that is a fixed part, an IC tag seal cutting means 7. The main difference from the first embodiment described above is that the two blade portions are disposed, and further, that the IC tag seal attaching portions 302 and 312 are provided with two cutting means recesses. Hereinafter, the difference will be mainly described.

  As shown in FIGS. 13 to 20, the control board case of the second embodiment is a PUSH portion as a movable portion in which the protective case 4 is movably supported and pushed into a base member 42 as a fixed portion. 41, and the push portion 41 is pushed in, and the engagement claw portions 422a and 422b of the protective case 4 and the engagement recesses 320a and 320b of the IC tag seal sticking portions 302 and 312 are released. A release mechanism, and the IC tag seal cutting means 7 is disposed on the inner surface of the PUSH portion 41 so as to face the tip portions of the IC tag seal attaching portions 302 and 312.

FIG. 13 is a perspective view illustrating the IC tag seal sticking portions 302 and 312 in detail.
The IC tag sticker pasting portion 302 protrudes from a part of the front case side surface 303, which is the left side surface of the front case 30, and includes a front end surface 302a, an inclined surface 302b, a vertical surface 302c, and a side surface 302d. The distal end surface 302a is formed with a cutting means recess 304 having an elongated rectangular shape that allows the blade portion 70a of the IC tag seal cutting means 7 described later to enter.

  Similarly, the IC tag seal sticking portion 312 protrudes from a part of the rear case side surface 313 that is the left side surface of the rear case 31, and includes a front end surface 312a, an inclined surface 312b, a vertical surface 312c, and a side surface 312d. The distal end surface 312a is formed with a cutting means recess 314 having a long rectangular shape that allows another blade portion 70b of the IC tag seal cutting means 7 described later to enter.

  As shown in FIG. 14, the IC tag seal 6 is pasted so as to straddle the IC tag seal pasting portion 302 of the front case 30 and the IC tag seal pasting portion 312 of the rear case 31. That is, the IC tag seal 6 is pasted on the IC tag seal pasting portions 302 and 312 so that the cross section of the short side of the IC tag seal 6 is substantially U-shaped. Further, the cutting means recesses 304 and 314 provided in the front end surfaces 302 a and 312 a of the IC tag seal attaching portions 302 and 312 are entirely hidden by the attached IC tag seal 6.

  Next, a specific configuration of the protective case 4 of the second embodiment will be described with reference to FIGS.

  15 is a perspective view showing a state in which the protective case 4 is attached to the IC tag seal attaching portions 302 and 312. FIG. 16 is an exploded perspective view for explaining a specific configuration of the protective case 4. FIG. It is sectional drawing which shows the cross section along the AA line in 15. FIG.

  As shown in FIG. 15, the protective case 4 attached to the IC tag seal attaching portions 302 and 312 is roughly divided into a push portion 41 that is a movable portion configured to be able to be pushed into other portions, and the push portion. It is comprised from the base member 42 which is a fixing | fixed part which supports 41 freely. Moreover, both of these PUSH part 41 and the base member 42 are comprised with the translucent material.

  As shown in FIG. 16, the PUSH portion 41 is marked with “PUSH” on the outer surface, and protrudes in the vertical direction from the center of the plate 410 to be pushed when it is pushed and the longitudinal ends of the plate 410. The two blade portions 70a, 70b of the IC tag seal cutting means 7 extend in parallel along the longitudinal direction of the inner surface of the plate 410 (inside the protective case). Exists.

  On the other hand, the base member 42 can be expanded by notching the surrounding member 420 surrounding the IC tag seal sticking portions 302 and 312 so as to surround the four sides, and the left side surface 420a and the right side surface 420b of the surrounding member. The expanded pieces 421a, 421b and springs 43a, 43b, 43c, 43d whose one ends are locked to the four corners of the inner wall of the surrounding member 420 and whose other ends are locked to the four corners of the PUSH portion 41. It is comprised from the spring support parts 424a, 424b, 424c, 424d elastically supported.

  The spread pieces 421a and 421b are formed by notching so as to leave a part from the lower end to the upper end of the left side surface 420a and the right side surface 420b of the surrounding member 420, and constant when a predetermined force is applied. It can be expanded in the range of.

Further, as shown in FIG. 17, the expansion pieces 421a and 421b are engaged with engagement recesses 320a and 320b formed in the IC tag seal sticking portions 302 and 312 on the inner surfaces (inside the protective case). Joint claw portions 422a and 422b, and engagement release portions 423a and 423b that protrude from the engagement claw portions 422a and 422b at a predetermined interval are disposed.

  The engaging claw portions 422a and 422b have tapers 4220a and 4220b, while the disengaging portions 423a and 423b are formed by inclined surfaces opposite to the tapered portions 4220a and 4220b of the engaging claw portions. Disengagement tapers 4230a and 4230b.

  The plate 410 elastically supported by the springs 43a, 43b, 43c, and 43d has a spring length adjusted to be positioned at the same height as the top surface of the surrounding member 420 in a free state. It is inserted into the surrounding member 420 so as to be able to be pushed inward from the free state against the biasing force of the spring.

  The operation and effect of the control board case of the second embodiment having the above-described configuration will be described below.

In the control board case of the second embodiment configured as described above, when the protective case 4 is pushed in to be attached to the IC tag seal attaching portions 302 and 312, as shown in FIGS. 18 (A) to (C). , the engaging claw portion 422a of the protective case 4, 422b of the tapered 4220A, the inclined surface 302 b of the and 4220B IC tag seal pasting unit 302, 312, in contact with 312b, the expansion tabs 421a, 421b are outwardly Expand. As a result, the protective case 4 can be further pushed into the IC tag seal sticking portions 302 and 312, and the engaging claws 422 a and 422 b of the spread pieces 421 a and 421 b are spread to the IC tag seal sticking portion. The protective case 4 is pushed in until the engagement recesses 320a and 320b of the 302 and 312 are reached. When the engagement claw portions 422a and 422b reach the engagement recesses 320a and 322b, the expansion claws 421a and 421b return from the expanded state to the natural state and enter the engaged state. Installation of the protective case 4 is completed.

Next, the operation when the protective case 4 is removed will be described with reference to FIG.
From the mounted state of the protective case 4 shown in FIG. 19A, when the plate 410 of the PUSH part 41 marked “PUSH” is pushed on the outer surface of the protective case 4 as shown in FIG. 19B, The plate 410 is pushed into the surrounding member 420 against the urging force of the springs 43a, 43b, 43c, and 43d that elastically support the four corners of the plate 410. Since the engagement release bars 411a and 411b project from the inner surface of the plate 410, the engagement release bars 411a and 411b are both pushed into the interior as the plate 410 moves. Then, the tip end portions of the disengagement bars 411a and 411b come into contact with the disengagement tapers 4230a and 4230b of the expanding pieces 421a and 421b, and when further pushed, the disengagement bars 411a and 411b are disengaged from the disengagement taper. In order to push the inclined surfaces of 4230a and 4230b, the expanding pieces 421a and 421b are expanded outward.

  Accordingly, as shown in FIGS. 19B and 19C, the engaging claws 422a and 422b of the expanded pieces 421a and 421b are detached from the engaging recesses 320a and 320b of the IC tag seal attaching portions 302 and 312. Then, the engaged state is released, and the protective case 4 can be removed. Therefore, the protective case 4 is extracted while maintaining the state where the plate 410 is pushed into the surrounding member 420 until the protective case 4 is completely extracted.

  19B and 20, when the plate 410 is pushed in, the two blade portions 70a and 70b of the IC tag seal cutting means 7 disposed on the inner surface of the plate 410 are The IC tag seal 6 is cut and penetrated, and enters the cutting means recesses 304 and 314 of the IC tag seal attaching portions 302 and 312. At this time, the two blade portions 70a and 70b surely cut the two cutting portions 62a and 62b that face diagonally across the IC chip 63 of the antenna portion 62 of the IC tag seal sticking portion 302.

  The control board case of the second embodiment having the above-described action is interlocked with a pusher 41 that is a movable part that is movably supported and pushed against the surrounding member 420 that is a fixed part by an unauthorized person. Then, the unlocking mechanism releases the locked state between the expanding pieces 421a and 421b of the protective case 4 and the engaging recesses 320a and 320b of the IC tag seal attaching portions 302 and 312. Since the blade portions 70a and 70b of the IC tag seal cutting means 7 disposed on the inner surface of the portion 41 so as to oppose the tip portions of the IC tag seal sticking portions 302 and 312 cut the IC tag seal 6, control such as ROM exchange For the purpose of cheating on the board, there is an effect of reliably detecting the act of removing the protective case to open the control board case.

In addition, as described above, when the IC tag seal is cut only at one location and the cut surface is returned to its original position, the communication function by the IC chip and the antenna portion is accompanied by the remaining effective range of the antenna portion. However, in the pachinko gaming machine 1 according to the second embodiment, the IC tag seal cutting means 7 includes two blade portions 70a and 70b, and 2 of the antenna portion 62 of the IC tag seal 6 is used. The above-mentioned problem is solved by cutting the portion to cut the effective range of the antenna portion 62 of the IC tag seal 6 to the range where the communication function with the reader / writer does not work, and the IC chip 63 and the antenna portion The communication function with 62 can be surely erased, and the presence or absence of IC tag seal cutting facts can be detected at the time of inspection, and unauthorized actions such as tampering with the control board can be accurately grasped. There is an effect that.

  Further, in the control board case of the second embodiment, since the main control board case 3 is constituted by a front case 30 and a rear case 31 that are separable from each other, the main control board 5 to be tampered with is accessed. In order to do this, it is essential to remove the protective case 4 attached so as to straddle the front case 30 and the rear case 31. However, an unauthorized person tries to remove the protective case 4 and pushes the PUSH as a movable part. When the portion 41 is pushed in, the IC tag seal cutting means 7 always cuts the IC tag seal 6, so that it is possible to reliably leave a trace of fraud.

  Further, the control board case of the second embodiment forms cutting means recesses 304 and 314 at positions corresponding to the two blade portions 70a and 70b of the IC tag seal cutting means 7 of the IC tag seal sticking portions 302 and 312. Since the clearance space for the blade portions 70a and 70b after the IC tag seal 6 is cut is secured, the IC tag seal 6 can be cut more reliably by the IC tag seal cutting means 7.

  Further, in the control board case of the second embodiment, since the PUSH part 41 and the base member 42 constituting the protective case 4 are made of a translucent material, the inside of the protective case 4 (for example, the IC tag seal 6) And the presence of the IC tag seal cutting means 7, as well as the engagement state and the disengagement mechanism) can be grasped from the outside, giving an anxiety that the trace of fraudulent acts remains for the fraudster. This acts as a deterrent and has the effect of preventing fraud.

In the control board case of the second embodiment, the disengagement bars 411a and 411b of the PUSH part 41 are integrally interlocked with the IC tag seal cutting means 7 and the plate 410. Since the release bars 411a and 411b and the expanded pieces 421a and 421b of the surrounding member 420 are constituted by independent members, only the expanded pieces 421a and 421b move freely when the protective case 4 is attached. In this case, the IC tag seal 6 is not cut, but when the protective case 4 is to be removed, the IC tag seal 6 is surely cut in conjunction with the removal operation and the protective case 4 is to be removed. Since the IC tag seal 6 is cut only when a fraud occurs, if there is no fraud, or if the fraudulent acts In the case where a serious fraud (opening of the main control board case 3, tampering of the main control board 5, etc.) has not been performed, such as when giving up before removing the protective case 4 while confirming, It is possible to accurately detect only the occurrence of a serious fraud in which the protective case 4 is removed.

  As shown in FIGS. 21 to 24, the control board case of the third embodiment is provided with an external cover portion so that the spread pieces 421a and 421b cannot be directly accessed, and the spread operations of the spread pieces 421a and 421b. In order to smoothen the above, the expansion pieces 421a and 421b are disposed on the surrounding member 420 via a spring material, and further, the constituent member of the protective case 4 is formed of a non-translucent material. This is the main difference from the second embodiment, and the difference will be mainly described below.

  As shown in FIGS. 21 and 22, the control board case of the third embodiment is similar to the pachinko gaming machine of the second embodiment to surround the spread pieces 421a and 421b. The shield covers 45a and 45b are integrally formed by injection molding an opaque non-translucent material.

  Specifically, the expanding pieces 421a and 421b are respectively disposed in the gap portions of the left side surface 420a and the right side surface 420b having a substantially U-shaped shape of the surrounding member 420, and are arranged at the expansion support ends. It is fixed to the left side surface 420a and the right side surface 420b by connecting deformation springs 44a and 44b that allow the expansion pieces 421a and 421b to expand, and the outward expansion of the protective case is restricted. . The connecting deformation springs 44a and 44b are constituted by leaf springs, and substantially function as hinge portions between the expanding pieces 421a and 421b and the left side surfaces 420a and 420b by elastic deformation. .

  In addition, the control board case of the third embodiment includes shielding covers 45a and 45b that shield the structure of the expanding pieces 421a and 421b from the outside so as to be invisible from the outside, and is connected to both ends of the surrounding member 420, respectively. The

  Further, in the control board case of the third embodiment, not only the shielding covers 45a and 45b but also the members constituting the protective case such as the surrounding member 420 and the plate 410 are made of a non-translucent material. is there.

  The operation and effect of the control board case of the third embodiment having the above-described configuration will be described below.

  In the control board case of the third embodiment configured as described above, if the protective case 4 is to be attached to the IC tag seal attaching portions 302 and 312, as shown in FIGS. As in the embodiment, the tapered portions 4220a and 4220b of the engaging claws 422a and 422b of the protective case 4 are in contact with the inclined surfaces 302a and 312b of the IC tag seal attaching portions 302 and 312 so that the spread pieces 421a and 421b are It is expanded outward against the regulating force of the connecting deformation springs 44a and 44b. As a result, the protective case 4 can be further pushed into the IC tag seal sticking portions 302 and 312 and further pushed in with the expanded pieces 421a and 421b maintained in an expanded state. The engaging claws 422a and 422b of the spread pieces 421a and 421b reach the engaging recesses 320a and 320b of the IC tag seal sticking portions 302 and 312 and the engagement force is controlled by the restriction force of the connecting deformation springs 44a and 44b. Engagement with the joint recesses 320a and 320b completes the mounting of the protective case 4.

  The distance d between the spreading pieces 421a and 421b and the inner walls of the shielding covers 45a and 45b is set to an appropriate distance so as not to obstruct the spreading operation of the spreading pieces 421a and 421b.

  As shown in FIG. 24, the operation when the protective case 4 is removed is basically the same as that of the second embodiment. When the plate 410 is pushed in, the engaging claws 422a and 422b are engaged. Is released, and the IC tag seal 6 is cut by the IC tag seal cutting means 7.

  In the control board case of the third embodiment, the members constituting the protective case 4 including the shielding covers 45a and 45b are integrally formed of a non-translucent material as described above. When removing the protective case 4, it is impossible to grasp from the outside what kind of structure the protective case 4 has.

  Since the control board case of the third embodiment having the above-described operation has the same basic configuration as that of the second embodiment, the IC tag seal 6 is appropriately protected from the direct contact with the outside by the protective case 4 in normal times. At the same time, when the protective case is pushed in to perform a fraud, it is possible to avoid accessing the spread pieces 421a and 421b directly from the outside and to carry out a fraud such as falsification of the main control board 5. There is an effect that it is possible to accurately grasp that there is.

Further, the control board case of the third embodiment is configured so that the peripheral mechanism of the spread pieces 421a and 421b is covered with the cover covers 45a and 45b so that it cannot be seen from the outside and cannot be directly accessed. Therefore, it is possible to cope with an action that destroys the fraud detection function by directly opening the spread pieces 421a and 421b from the outside.

  Further, in the control board case of the third embodiment, the members constituting the protective case 4 including the shielding covers 45a and 45b are made of a non-translucent material. Since it is not possible to grasp and, therefore, a fraudulent person who has accidentally removed the protective case 4 inadvertently recognizes that the trace of the fraud has remained due to the cutting of the IC tag seal. There is an effect of suppressing (opening of the control board case, tampering of the control board, etc.).

  As shown in FIGS. 25 to 28, the control board case of the fourth embodiment is mainly different from the above-described embodiment in that the engaging portion of the protective case 4 is configured by a reversing mechanism. Hereinafter, the difference will be mainly described.

As shown in FIGS. 25 and 26 , in the control board case of the fourth embodiment, the protective case 4 is formed by projecting the reversing members 46a and 46b provided with the engaging claws 422a and 422b of the protective case 4. In the state, the IC tag seal sticking portions 302 and 312 are locked in the engaging recesses 320a and 320b. On the other hand, when the protective case 4 is pushed from the locking position, the reversing members 46a and 46b are reversed and become concave. The IC tag seal cutting means 7 is provided on the inner surface of the protective case 4 so as to face the tip portions of the IC tag seal sticking portions 302 and 312. .

  As shown in FIG. 25, the protective case 4 is composed of a left side surface 40a, a right side surface 40b, a front end surface 40c, a front hand surface 40d and a back surface 40e which are largely made of a non-translucent material. , 312 is attached so as to cover it. Further, return members 47a and 47b for returning reverse members 46a and 46b, which will be described later, are inserted through substantially the center portions of the left side surface 40a and the right side surface 40b.

  Further, as shown in FIG. 26, on the inner surfaces of the left side surface 40a and the right side surface 40b of the protective case 4, there are recessed reverse member recesses 48a, 48b for inserting the reverse members 46a, 46b, The reversing members 46a and 46b are gripped by the reversing member support portions 49a and 49b disposed at the ends of the reversing member recesses 48a and 48b.

  Each of the reversing members 46a and 46b is constituted by a leaf spring made of a spring material formed by bending a thin plate such as stainless steel, and has a substantially V-shape projecting inward of the protective case 4 at a substantially central portion in the longitudinal direction. Engaging claw portions 422a and 422b are provided. The engaging claw portions 422a and 422b are formed with tapers 4220a and 4220b constituted by a vertical surface and an inclined surface parallel to the engaging concave portions 320a and 320b.

Further, the reversing members 46a and 46b are reversed when the engaging claw portions 422a and 422b are displaced by a force exceeding a certain amount in the left-right direction in FIG. The state can be switched. For example, when the engaging claw portions 422a and 422b are reversed from a convex state engaged with engaging concave portions 320a and 320b of IC tag seal sticking portions 302 and 312 described later and switched to a concave state, the protective case 4 By pushing the return members 47a and 47b inserted through the left side surface 40a and the right side surface 40b of the outer surface toward the inside of the protective case 4, it can be reversed and returned to the convex state again. In addition, unless the external force is applied in this way, the reversing members 46a and 46b are configured to maintain a convex state or a concave state which is their current shape.

  Further, an IC tag seal cutting means 7 having two blade portions 70a and 70b is formed on the inner surface of the front end surface 40c of the protective case 4 so as to extend as in the second and third embodiments. Yes.

  On the other hand, the left side surface 324a and the right side surface 324b of the IC tag seal pasting portions 302 and 312 are engaged with the first vertical surfaces 324a1 and 324b1 and the engaging recesses 320a and 422b of the protective case 4, respectively. 320b, inclined surfaces 324a2 and 324b2, and second vertical surfaces 324a3 and 324b3.

  Further, like the second embodiment and the third embodiment, cutting means recesses 304 and 314 are formed on the front end surfaces 324c of the IC tag seal attaching portions 302 and 312 at positions corresponding to the two blade portions 70a and 70b.
