Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stick-type sensor to be attached and used, and is particularly suitable as a sealing seal.

[0002]

2. Description of the Related Art Inconveniences arise when opening after having been closed once, a sealing seal is attached (closed) to the opening / closing portion of a symmetrical object so that the opening can be easily recognized. For example, recent pachinko machines are configured to play a game under the control of a microcomputer (control device) including a ROM, a RAM, a CPU, and the like. The device is sealed by applying a sealing seal. More specifically, a ROM storing a legitimate game program is mounted on a board of the control device, and the board is housed in a transparent case.
Then, if this ROM is replaced with a fraudulent ROM storing a fraudulent game program, the game becomes unhealthy. For this reason, in order to prevent the case from being opened and remodeled, the control device seals the case by attaching a sealing seal to the open / close portion of the case.

[0003] As a conventional sealing seal used for such a sealing, two sealing materials are laminated by an adhesive layer formed therebetween, and a strong adhesive layer is formed on the lower surface of the lower sealing material. There is one configured so that it can be strongly adhered to an open / close portion of an adherend by the adhesive force of an adhesive layer. Then, if the sealing seal is illegally peeled off, only the upper sealing material is peeled off, and the lower sealing material remains on the surface of the adherend due to the adhesive force of the strong adhesive layer. Characters such as “opened” are printed on the surface (upper surface) of the lower sealing material so that the trace that has been peeled off can be clearly identified.

[0004] A security system in which a switch such as a micro switch or a magnet switch is provided on an opening / closing portion of a door or the like and which issues an alarm based on a signal from the switch when the switch is opened has been conventionally used.

[0005]

However, it is not possible to reliably prevent unauthorized opening only by pasting a conventional sealing seal. For example, if a fake seal is pasted on the original position after the proper seal is peeled off and illegally opened, the trace of the proper seal is obscure and difficult to determine.

Further, in a security system in which a magnet switch or the like is provided on the opening / closing portion, if a short circuit or a work using a strong magnet is performed, the sensor function of the switch is lost, and the security function is lost. And it was difficult for the conventional switch to effectively prevent tampering by a fraudulent person.

Accordingly, the present invention provides a seal-type sensor which can effectively prevent improper tampering and can be used as a seal seal, and a seal monitoring method using the seal-type sensor. The purpose is to provide.

[0022]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a plan view of the seal-type sensor 1, and FIG. 2 is an enlarged sectional view of the seal-type sensor 1 shown in FIG.

As shown in FIG. 2, the seal type sensor 1 comprises a conductive first seal member 2 and a conductive second seal member 3 formed between the two seal members 2 and 3. The sensing unit 12 is formed by laminating by the adhesive force of the adhesive layer 4 and integrated in a conductive state, and the adhesive layer 5 is formed on the surface (the lower surface of the first sealing material 2 in the figure) in the integrated state. The strong adhesive force of the adhesive layer 5 allows the adhesive layer 5 to adhere to the surface of the adherend 6.

The first sealing material 2 and the second sealing material 3 may be conductive materials such as aluminum foil. Then, as shown in FIG. 4, the first sealing material 2 is printed on the front surface (the surface on the side of the second sealing material 3) with the word "open" as a trace of peeling, and the back surface (the surface on the side of the adherend 6). ) Is provided at one end (the left side in the figure) and the adhesive layer 5 is formed, and the lead wire 8 is connected to the first conductive part 7. The first energizing unit 7 is a security device (not shown)
This is a portion for connecting a lead wire 8 for electrically connecting between the components, and is made of, for example, a conductive adhesive or the like.
You may comprise a connection pin, a connector, etc. Further, the adhesive layer 5 to be attached to the adherend 6 has a stronger adhesive force than the adhesive force of the conductive adhesive layer 4 for laminating and attaching the first and second seal materials 2 and 3.

On the other hand, as shown in FIG. 1, on the surface of the second seal material 3 (the surface opposite to the first seal material 2), the characters "inspection seal" indicating that it is a seal are printed. At the same time, a second power supply unit 9 is provided at the end. In the embodiment shown in the drawings, an electric resistance 10 is interposed between the second energizing section 9 and the second sealing material 3. This electric resistance 10
May be connected to a resistor or a resistor chip, or may be provided by printing a resistance layer on the surface of the second sealing material 3. The second energizing section 9 is a section to which the lead wire 11 is connected, similarly to the first energizing section 7 of the first sealing material 2.

On the back surface of the second seal material 3 (the surface on which the first seal material 2 is to be polymerized), a conductive adhesion layer 4 made by kneading fine powder such as carbon or copper to have conductivity. To form The conductive adhesive layer 4 is set to have a weaker adhesive force than the adhesive layer 5 formed on the lower surface of the first sealing material 2. In order to obtain the adhesive force of the conductive adhesive layer 4, an adhesive layer may be used, but a pressure-bonded layer may be used. In short, any layer having a predetermined adhesive force and being removable can be used.

When the sensing portion 12 is formed by laminating and integrating the first sealing material 2 and the second sealing material 3 by the adhesive force of the conductive adhesion layer 4, the conductivity of the conductive adhesion layer 4 The first conducting section 7 and the second conducting section 9 conduct. That is, the second power supply unit 9 is electrically connected to the first power supply unit 7 via the sensing unit 12. When the first sealing member 2 and the second sealing member 3 are bonded together, the first energizing portion 7 is connected to one end (the left side in the drawing), and the second energizing portion 9 is connected to the other end (the right side in the drawing). It is desirable to arrange them.

Next, an example of use of the above-mentioned seal type sensor 1 will be described. The use example shown in FIG. 5 is an example in which the control device 15 of the pachinko machine is sealed. This control device 15
By attaching a transparent box-shaped case 18 to a substrate 17 provided with a connector 16 at the end,
It is configured to cover electronic components such as U19. Then, in order to prevent the internal electronic parts from being replaced or remodeled by opening the case 18, the opening / closing portion of the case 18 (a portion that separates when the case 18 is opened, (Part straddling between the substrate 17)
Then, the seal type sensor 1 is attached to the opposing portion, and each lead wire of both the seal type sensors 1 and 1 is electrically connected to the sensor input side of the security device. That is, one end of the seal type sensor 1 is attached to the case 18 and the other end thereof is attached to the substrate 17, and the seal type sensor 1 is attached while being bridged over the open / close portion to seal the open / close portion.

In this embodiment, the adhesive layer 5 is formed on the entire lower surface of the seal type sensor 1 and the entire lower surface is attached to the surface of the opening / closing portion. For example, an adhesive may be applied to, for example, four corners of the seal-type sensor 1, and the seal-type sensor 1 may be fixed to the open / close portion of the case 18 by the adhesive force of the adhesive. In short, one of the open / close parts (for example, case 18)
It is sufficient that one end of the seal type sensor 1 is fixed to the other end of the seal type sensor 1 and the other end of the open / close portion (for example, the substrate 17) is fixed to the other end. It is desirable that the adhesive has solvent resistance such as a so-called instant adhesive.

Further, the security device detects the occurrence of an abnormality by monitoring a signal from a sensor such as the seal sensor 1, that is, an electrical change between both energized parts of the sensor, and stores the occurrence of the abnormality, It is a device that can notify. For example, it may be configured to be built in a calling lamp provided for each pachinko machine, and to blink the lamp or display it on an LED display when an abnormality is detected. In addition, a security device function is provided in addition to the management device for managing the pachinko machines in the store, and the seal type sensor 1 of each pachinko machine is electrically connected to the management device, and the management device detects and displays an abnormality. Or you may.

In a normal state of the seal type sensor 1, that is, a state where the seal type sensor 1 is not peeled or cut, the first
Since the conducting section 7 and the second conducting section 9 are conducting, this conducting state (ON state) is detected by the security device, and
Judge as normal.

On the other hand, if the wrongdoer tries to peel off the seal type sensor 1 to open the case 18, the adhesion of the conductive adhesion layer 4 between the first and second seal materials 2 and 3 is weak. As shown in FIG. 3, the second sealing material 3 is peeled off from this portion, and the first sealing material 2 is controlled by the strong adhesive force of the pressure-sensitive adhesive layer 5 or the adhesive force of the adhesive to the control device 15 (the adherend 6). Remains. Since the letters "open" are printed on the surface of the first sealing material 2 remaining on the controller 15 side, it is easy to see that it is peeled off just by looking from the outside, similarly to the conventional sealing seal. It can be visually recognized (FIG. 4).

Further, when the seal type sensor 1 according to the present invention is used, it is possible for the store clerk to find out the fact of electrical separation without having to visually check the control device 15 each time. That is, when the second seal material 3 is peeled off and separated from the first seal material 2, the conduction between the first energizing unit 7 and the second energizing unit 9 is cut off. ) Can be detected. In the security device, from the conduction state to the disconnection state (from the ON state to the OF state)
F state) can be sensed,
In other words, since an abnormal signal is sent from the seal-type sensor 1, it is possible to detect the abnormal state, and based on the detected abnormal state, it is possible to store the abnormal state, display an alarm, and generate an alarm sound.

When the case 18 is opened by cutting with the cutter 20 or the like without peeling off the seal sensor 1, as shown in FIG. 2, the seal sensor 1 is cut in the thickness direction by the cutter 20 or the like. Therefore, the conduction is cut off at the cut portion, and accordingly, the conduction between the first conducting section 7 and the second conducting section 9 disappears. Therefore, as in the case where the second seal material 3 is peeled off, an abnormal signal is sent from the seal sensor 1 to the security device,
As a result, an abnormality can be detected, and based on the detected abnormality, storage of the occurrence of an abnormality, alarm display, generation of an alarm sound, and the like can be performed. When the case 18 is forcibly opened, the seal-type sensor 1 is cut in the middle in the longitudinal direction, so that the conduction is cut off as described above and the sensor is turned off, so that an abnormality can be detected.

Further, it is conceivable that a skillful cheating person may short-circuit the two lead wires 8 and 11 of the seal-type sensor 1 while trying to peel them off while maintaining the state of conduction between the two lead wires 8 and 11. Can be However, since the seal type sensor 1 in the present embodiment has the electric resistance 10, when the both the lead wires 8 and 11 are short-circuited, the electric current provided between the second energizing portion 9 and the second seal material 3 is provided. Resistance 10
Since the conduction is made without passing through, the occurrence of an abnormality can be detected by detecting this with the security device.

That is, as shown in FIGS. 6A and 6B,
The electric resistance 10 provided on the seal type sensor 1 is a first resistance. One lead 8 is connected to a power supply via a second resistance 22 on the security device side, and the other lead 11 is connected to a power supply via a third resistance 23. FIG. 6 shows that when a connection is made and a monitoring circuit monitors a change in voltage (voltage ratio) between a contact voltage V1 between the first resistor 10 and the third resistor 23 and a contact voltage V2 between the first resistor 10 and the second resistor 22. As shown in (2), when the current-carrying portions 7 and 9 are short-circuited by the cord 25, the electric resistance of the first resistor 10 is lost, so that the voltage ratio changes and this change can be sensed as abnormal. . Therefore, an abnormality can be detected even if the lead wires 8 and 11 are short-circuited. Also, if one of the lead wires 8 and 11 is cut, the second seal material 3 is peeled off, resulting in the same state (equivalent) as the state where conduction is cut off. Can be detected.

It is almost impossible to peel off the entire seal-type sensor 1 with the cutter 20 or a razor blade, because the adhesive force of the adhesive layer 5 is strong. First energizing section 7 disposed on the lower surface of sealing material 2
Or the lead wire 8 may be damaged or cut, so that the voltage ratio changes and abnormality is detected in the same manner as described above.

As described above, in the present embodiment, the adherend 6
One end of the seal type sensor 1 is fixed to the case 18 which is one of the open / close portions of the (control device 15), and the other end of the seal type sensor 1 is fixed to the substrate 17 which is the other end of the open / close portion. Then, due to an external action such as a tension for peeling the seal-type sensor 1 from the opening / closing portion, a cut of the seal-type sensor 1 by the cutter 20 or the like, or a short circuit between the two lead wires 8 and 11, The first seal material and the second seal material 3 (that is, the sensing unit 12) change their electrical state by cutting off conduction or changing the resistance value. This change in the electrical state is detected by the security device energizing the first energizing unit and the second energizing unit. Therefore, by monitoring the change in the electrical state of the first sealing material and the second sealing material 3 in the integrated state, it is possible to monitor the sealing and unsealing of the open / close portion of the adherend 6.

Although the above-mentioned seal type sensor 1 is constructed by laminating two seal members 2 and 3 having the same size and shape, the first seal member 2 and the second seal member 3 are integrated in a conductive state. When the seal material is to be peeled off from the surface of the adherend 6, one seal material is separated from the other and peels off, but the other seal material may be any seal that remains as it is adhered to the surface of the adherend 6.

For this reason, the lower first sealing material 2 to be adhered to the surface of the adherend 6 is cut into an elongated cross shape, and the second sealing material 3 having a size capable of covering the cross shape is electrically conductive. The layers may be laminated via the adhesion layer 4. The first energizing section 7 is provided on the first sealing member 2 and the second energizing section 9 is provided on the second sealing member 3 in the same manner as in the above embodiment. In the same manner as in the above embodiment, when the wrongdoer tries to peel off the seal-type sensor 1 having such a configuration, the rectangular second seal member 3 separates from the cruciform first seal member 2 and both energizing portions are separated. Since the conduction between 7, 9 is cut off, an abnormality can be detected.

The means for laminating the first sealing material 2 and the second sealing material 3 to conduct electricity is not limited to the conductive adhesion layer 4 made of a conductive adhesive layer. For example, the sealing materials 2 and 3 may be electrically connected to each other by spot pressure bonding after excluding a part of the adhesive layer after the adhesive layer is laminated by an adhesive layer having no conductivity.

Further, the first sealing material 2 having conductivity and the second sealing material 3 having conductivity are integrated in a conductive state,
An adhesive layer 5 is formed on the surface in this integrated state, and is adhered to the surface of the adherend 6 by the adhesive force of the adhesive layer 5, and is cut by receiving the tension when trying to peel off from the adherend surface. A cut portion to be formed is formed in the middle of conduction between the first seal material 2 and the second seal material 3, and the cut portion cuts the first energizing portion 7 and the second seal material 3 provided on the first seal material 2. You may comprise so that the conduction with the provided 2nd electric conduction part 9 may be interrupted.

For example, as shown in FIG. 7, the ends of the elongated portions of the substantially cross-shaped conductive base seal material 30 are used as the first seal material 2 and the second seal material 3, and the first seal material 2 is formed. The first energizing part 7 is provided on the second sealing material 3, and the second energizing part 9 is provided on the second sealing material 3. The part 31 is formed. Then, a rectangular covering sealing material 32 is laminated on the upper surface of the cruciform conductive base sealing material 30 with an adhesive layer,
A strong adhesive layer adheres more strongly between the covering sealing material 32 and the cut portion 31 than other portions. In addition, the lower surface portion of the cut portion 31 (the hatched portion in FIG. 7) does not form an adhesive layer or weakens the adhesive force. In short, the cut portion 31 is covered with the sealing material 32 more than the adherend.
Set strong adhesion to the side.

The seal type sensor 1 having the above configuration
Is adhered to the control device 15 (the adhered object 6) and sealed, and if the wrongdoer tries to peel off the seal, for example, from the right side in FIG.
When the right side of 2 starts to peel off from the base seal material 30 and the peeled portion reaches the cut portion 31, the adhesive force of the cut portion 31 to the covering seal material 32 is stronger than the other portions, while the adhesive force to the control device 15 is higher. Is weak, so this cutting portion 31
Tends to rise while adhering to the covering sealing material 32.
For this reason, the pulling force at the time of peeling this portion acts on the weak portion 26 of the cutting portion 31, and the weak portion 26 is cut by the above pulling force. Thus, the base sealing material 3
When the zero cutting portion 31 is cut, the cut-off interrupts the conduction between the first conducting portion 7 and the second conducting portion 9. Therefore, according to the present embodiment, if the cutting unit 31 is cut even during the separation, the security device can detect the fraud. The same is true if you start peeling from the opposite side, and no matter where you peel from,
When the cutting section 31 in the middle is cut, the first energizing section 7 and the second
The conduction with the energizing section 9 is cut off, and an unauthorized peeling action can be detected.

Further, one conductive seal is divided into a first seal material 2 and a second seal material 3, and when the conductive seal is to be peeled off, it is cut from a fragile portion formed at the boundary of this section, and both seal materials 2 and 3 are separated. 3 may be detached.

For example, the seal type sensor 1 shown in FIG.
Is formed by forming the fragile portion 26 in one conductive seal (for example, an aluminum sheet material) into a substantially blade shape, and by removing the blade-shaped first seal material 2 whose width is different from the middle, and removing the blade-shaped portion. The first sealing member 2 is provided with a first energizing section 7 and a lead wire 8 is connected thereto. The second sealing member 3 is provided with a second energizing section 9 and a lead is provided. The adhesive layer 5 may be formed on the entire lower surface of the seal by connecting the wires 11.

The fragile portion 26 may be formed, for example, by forming an extremely thin groove by half blanking or the like, or by forming a fine slit by a laser beam intermittently to form a perforated shape, and leaving the groove intermittently. The part becomes a conduction part. Since the fragile portions 26 have electrical conductivity, the first seal member 2 and the second seal member 3 are electrically connected. Further, in the present embodiment, since the fragile portion 26 is formed by the minute intermittent slit, the slit is formed so as to enter obliquely inward from the first energizing portion 8 side in the narrow width portion of the first sealant 2. In addition, a V-shaped slit is formed at a position where the slits from both sides intersect to form a cut portion, and the slit is formed so as to extend obliquely outward from the second conducting portion 9 side in a portion having a large width. To form a cut portion.

The seal type sensor 1 having such a configuration
When the fraudulent person attempts to forcibly peel off the sealing seal, the outer second sealing material 3 starts to peel off, and the peeled portion reaches the fragile portion 26. Then, since the first sealing material 2 is strongly adhered to the surface of the adherend 6 by the adhesive force of the adhesive layer 5, a tensile force acts on the fragile portion 26, and the fragile portion 26 is acted on by the action of the tensile force. Begins to cut. Then, when the second seal material 3 is peeled off, the conduction of the two seal materials 2 and 3 is cut off, so that an abnormality can be detected as in the above embodiment.

In the case of peeling from the left side in FIG. 8 during the peeling, for example, the peeling starts from the left end portion of the second sealing material 3, and the peeled portion faces a diagonally inside of the fragile portion 26 (cut portion). , The break line proceeds inward along the oblique slit, and when further separated, the break line reaches the V-shaped slit, and the portion provided with the first conducting portion 7 is separated from the other portion. . Therefore, the first energizing unit 7 and the second
The conduction with the conducting part 9 is cut off at the cutting part, so that the security device can detect unauthorized peeling. On the other hand, when peeling from the right side in FIG. 8, the peeling starts from the right end portion of the second sealing material 3, and when the peeled portion reaches a portion (cut portion) facing diagonally outward of the fragile portion 26, the break line is inclined. The second seal 3 is cut off in the longitudinal direction when further peeled off. Therefore, the conduction between the second energizing section 9 and the first energizing section 7 is interrupted by the cutting section, so that the security device can detect unauthorized peeling.

As described above, in the embodiment shown in FIG. 8, even if it is constituted by one conductive seal, since the conduction is interrupted during the peeling, the first seal material 2 and the second seal material 3 are completely separated. Unauthorized peeling can be detected even when the film is peeled to a state where it is separated, or even before completely peeled.

Further, the seal in the present invention is not limited to a seal made entirely of a conductive material as in the above-described embodiment, but may be formed by providing a conductive portion on an insulating seal base material. It may have conductivity. Further, the first sealing material 2 and the second sealing material 3
The sealing material is not limited to a physically partitioned one, and may be any sealing material that can change its electrical state due to, for example, a loss of conductivity due to an external action such as peeling or breaking.

For example, a conductor pattern is formed as a sensing portion on the surface of a relatively fragile and insulating sealing base material such as paper or synthetic resin film, and a first current-carrying portion is provided at one end of the conductor pattern and at the other end. The second conductive portion may be electrically connected, or a protective sheet may be coated on the surface of the seal base on which the conductive pattern is formed to integrate at least the conductive pattern of the protective sheet and the seal. Then, a part of the conductive seal may adhere to the protective sheet and be peeled off, or the conductive pattern may be broken when the seal base material is to be broken.

More specifically, the seal type sensor 1
In FIG. 9A, a protective sheet 41 (for example, a film made of synthetic resin) shown in FIG. 9B is superimposed on an upper surface of a seal base material (for example, a paper material) made of an insulating sheet material shown in FIG. Then, as shown in FIG. 10, the sheet is laminated and integrated by the adhesive force of the adhesive layer provided on the lower surface of the protective sheet 41, as shown in FIG.

On the upper surface of the seal base material 40, a thin strip-shaped conductor pattern 42 is formed by printing a conductive material (for example, conductive ink or silver paste) made of a good conductor. The conductive pattern 42 imparts conductivity to the seal base material 40 to form a conductive seal. The conductor pattern 42 functions as a sensing unit in the present embodiment. In addition, the lower surface of this seal base material 40
The background of the seal base material 40 is exposed as it is, and no adhesive layer is provided.

One end of the conductor pattern 42 formed on the upper surface is connected to the first energizing section 7 disposed at one end of the seal base 40.
The other ends of the conductor patterns 42 are respectively connected to the second conducting portions 9. In the middle of the conductor pattern 42, a main resistance 43 as an electric resistance of the seal type sensor is provided by printing a resistance layer or the like. For example, the resistive layer is formed by using a conductive ink containing carbon and having a resistance value. Further, a plurality of adjusting resistors 44 for adjusting the resistance value of the seal type sensor to a predetermined value are connected in parallel to the main resistor 43 provided in the middle of the conductor pattern 42. The adjusting resistor 44 is also provided by printing a resistance layer or the like. The main resistor 43 and the adjusting resistor 44 may be provided by soldering a resistor or a resistor chip.

The first energizing section 7 and the second energizing section 9 are arranged as shown in FIG.
10 (a) and the connector connecting portion 45 provided at the right end in FIG.
Are electrically connected to the outside via a connector 46 provided with a. Further, between the first energizing section 7 and the second energizing section 9, a dummy energizing section 4 which is not electrically connected is provided.
7 (three in the figure) are provided.

At the side edge of the seal base material 40, cut portions 48 extending from the outer peripheral edge to a position just before the conductor pattern 42 are formed at a plurality of places, and the break from the cut portion 48
It crosses over to 2. In addition, the cutout portion 48 in the present embodiment is a substantially T-shaped slit formed with its head facing the conductor pattern 42 side. The conductor pattern 42 is bent in a U-shape, for example, and is arranged close to the cut portion 48 so that the break from the slit immediately crosses the conductor pattern 42.

The above-mentioned protective sheet 41 is made of, for example, an insulating film colored in a dark color such as black, and has a size larger than that of the seal base material 40. For example, a synthetic resin or the like is used for this film, and an adhesive layer 51 (see FIG. 11) is formed on the lower surface thereof. Then, the lower surface of the protective sheet 41 is laminated on the upper surface of the seal substrate 40, and the protective sheet 41 and the seal substrate 40 are integrated by the adhesive force of the adhesive layer 51. In this integrated state, the conductor pattern 42, the main resistor 43, and the like provided on the seal base material 40 are covered by the protective sheet 41 and are difficult to see. Therefore, from the wrongdoer, the conductive pattern 42 is attached to the seal-type sensor 1 (sealing seal).
It is difficult to understand that electric circuits such as the resistors 43 and 44 are formed.

The adhesive strength of the adhesive layer 51 of the protective sheet 41 is set to be weaker than the adhesive strength of the adhesive layer 52 (see FIG. 11, described later) between the seal type sensor 1 and the adherend. In addition, the strength sufficient to break the protection sheet 41 itself in the middle, or the conductor pattern 42 and the main resistance 4
The strength is set to 3 or a strength sufficient to separate the adjusting resistor 44 from the seal base material 40. In short, the adhesive layer 51
Of the sensing portion (the conductor pattern 42) without peeling the seal-type sensor 1 from the adherend.
Etc.) are set to be strong enough to change the electrical state.

Next, an example of use of the seal type sensor 1 having such a configuration will be described. An example of use shown in FIG. 11 is an adherend 6 having a right-angled opening / closing portion such as a case of a pachinko machine control device (see FIG. 5) and a lid opening / closing portion.
Is sealed by a seal type sensor 1. FIG.
In 1, the adhesive layer 52 provided between the seal-type sensor 1 and the adherend 6 is an adhesive applied and bonded to at least four corners on the lower surface of the seal-type sensor 1. And
One end of the seal-type sensor 1 is one of the open / close parts (lid 6a)
The other end of the seal-type sensor 1 is fixed to the other of the open / close portions (the case 6b).

The adhesive layer 52 in this embodiment is formed by applying a solvent-resistant adhesive in a cured state. This is to prevent a wrongdoer from peeling off the seal-type sensor 1 by lowering the adhesive strength of the adhesive layer 52 with a solvent (solvent) such as alcohol. Examples of such an adhesive include an epoxy-based adhesive and an instant adhesive containing a desiccant. In addition,
When the open / close portion of the adherend 6 is sealed by the seal sensor 1, an adhesive is applied to the open / close portion of the adherend 6 to form an adhesive layer 52, and the seal sensor is attached to the applied portion. 1 (sealing base material 40) may be pressed to adhere the seal sensor 1 and the adherend 6 to each other, or an adhesive may be applied to the lower surface of the seal sensor 1 and then pasted. Good. Then, the seal-type sensor 1 stuck in this manner is covered and protected by the above-mentioned protection sheet 41.

When the wrongdoer tries to peel off the protective sheet 41 in an attempt to make an illegal work, for example, if he applies a pulling force to peel off the protective sheet 41 from the lower end side in FIG. Since the adhesive force of the adhesive layer 52 provided between the sensor 1 and the object 6 is very strong, the sealing base material 40 tends to remain on the object 6 (control device),
Stress concentrates on the right end of the T-shaped head of the cut portion 48, and finally, the seal base material 40 breaks from the right end of the T-shaped head.
This broken portion (for example, a portion indicated by reference numeral A in FIG. 9) extends toward the conductor pattern 42 and cuts the conductor pattern 42. When the conductor pattern 42 is cut,
Since the conduction between the second power supply units 7 and 9 is cut off, an abnormality can be detected in the same manner as in the above embodiment.

Even if the conduction of the conductor pattern 42 is not cut off, when the protection sheet 41 is peeled off, a part of the conductor pattern 42 and the main resistor 43 or the adjustment resistor 44 partially adhere to the protection sheet 41. As a result, the resistance value of the seal-type sensor 1 changes from a predetermined value. An abnormality can be detected by detecting a change in the resistance value. Even if only the protection sheet 41 is peeled off, since the conductor pattern 42 is printed with the conductive ink, the printed portion is almost always the seal base material 40.
Of the conductive pattern 42, and the conductive pattern 42 is cut off by being adhered to the protective sheet 41 and removed.

Similarly, even if the wrongdoer tries to forcibly peel off the seal-type sensor 1 together with the seal base material 40, the stress concentrates on the right end of the T-shaped head of the cut portion 48 due to the pulling force. Then, the seal base material 40 breaks from the right end of the T-shaped head and cuts the conductor pattern 42. Thereby, the conduction of the conductor pattern 42 is cut off, so that an abnormality can be detected.

As described above, according to this embodiment, the conductor pattern 42 provided on the seal base material 40 is formed in accordance with the act of peeling off only the protective sheet 41 or the seal base material 40.
Is interrupted or a part of the conductor pattern 42 is peeled off, and the electrical state of the sensing unit changes, so that an unjust act of breaking the seal can be reliably detected.

Also, in this embodiment, if the seal type sensor 1 is cut after the conductor pattern 42 (ie, the first energizing section 7 and the second energizing section 9) is short-circuited,
Since the resistance value of the seal-type sensor 1 is different between before and after the short circuit, as in the above-described embodiment, an abnormality can be detected based on the change in the resistance value. Further, the connector connecting portion 45 of the seal base 40 is provided with a total of five current-carrying portions, and three of the current-carrying portions are provided as dummy current-carrying portions 47. It is difficult to know which one of the current-carrying parts should be selected when short-circuiting the 9. Therefore, the fraudulent act of short-circuiting the conducting parts 7 and 9 can be prevented more reliably.

Incidentally, the protective sheet 41 described above is configured to be covered at the time of the sealing operation by using a synthetic resin film larger than the seal base material 40. However, the seal base material on which the conductor pattern 42 is formed is formed. 40 may be formed by laminating the surface in advance. In this case, a laminate film is formed by laminating (covering) the laminate film on the upper surface of the seal base material 40 and then thermocompression bonding. Note that, when a laminate layer is formed as the protective sheet 41, the protective function is the same as described above, but when the cut portion 48 is formed, the laminate layer is also cut at the same time. Occur more easily. Further, the protection sheet 41 larger than the seal can be effectively used in each of the above-described embodiments. In particular, in the case of the above-described embodiment in which the seal type sensor 1 is adhered with the adhesive layer 5, covering the large protective sheet 41 can prevent the adhesive layer 5 from being dissolved by the solvent. If the type of the solvent of the adhesive layer 51 of the protective sheet 41 and the type of the solvent of the adhesive layer 5 of the seal sensor 1 are made different, in other words, if the adhesive layer is formed by using an adhesive of a different solvent, a wrongdoer Makes it difficult to select a solvent, whereby the dissolution by the solvent can be more reliably prevented.

In the present invention, a temperature-sensitive element that changes the resistance or the thermoelectromotive force according to the temperature is connected to the main resistor 43 in series or in parallel, or used alone as a part of the sensing unit. It may be provided. In this case, when the temperature of the seal-type sensor 1 changes due to an external action (second external action) such as heating or cooling of the seal-type sensor 1, the resistance value or the thermoelectromotive force of the temperature-sensitive element changes. Then, the electrical state of the sensing unit is changed. Accordingly, the adhesive force of the adhesive layer 52 (or the adhesive layer 5) formed between the seal-type sensor 1 and the adherend 6 is reduced by heating or cooling the seal-type sensor 1, and the like. 1 can be effectively prevented.

The seal type sensor 1 according to the present invention
Is not limited to the sealing seal of the control device 15 such as a pachinko machine, a pachislot machine, a slot game machine, etc. Can also be used for things. For example, it can be used as a sensor for detecting the opening of a door or a sensor for detecting a disconnected connector.
