Description

  The present invention relates to an antitheft device mounted on an electronic circuit of an object from an IC card to a vehicle.

Conventional antitheft devices are keys, locks, alarm devices, monitoring devices, and the like, and use means for making an environment in which an object is difficult to steal against the behavior of the thief. Therefore, when these means are avoided, broken, or removed, there is a drawback that the effect as a theft countermeasure device is lost and the object is used by the thief.

Thus, in the past, once an object has reached the thief's hand, the object is left to the thief's intention, and the stolen owner has no choice but to catch the thief. In other words, the value of the object's use was passed directly to the thief.

There was no electronic circuit that had the function of moving the object that was in the thief's hand as if it had been broken, and there was a device that would eliminate the use value of the object in the thief's hand. Never before.

Until now, there has been no electronic circuit that has the function of an anti-theft device that can use an object freely and prevent the thief from using the object when it is stolen, and that is not intruded by the thief.

It is an electronic circuit that normally does not move normally, and only the administrator can make it move normally, it automatically returns to a state that does not move normally, and it is not invaded by thieves, Until now, there has been no electronic circuit that can be used for a moving body such as a vehicle.

  There has never been an antitheft device mounted on an IC card.

Electronic antitheft devices are for vehicles, but there are no other electronic antitheft devices that are widely used for objects.

Conventionally, as an example of an advanced antitheft device, there is an antitheft device called an immobilizer developed as an antitheft device for passenger cars. This is a method in which the vehicle computer identifies and recognizes the owner by inserting a key with an IC chip, and the engine will not start unless the correct identification signal is recognized by a transmitter incorporated in the key or the like. It is a mechanism. It is effective for vehicle theft due to the fact that the key cannot be counterfeited and the engine does not start without the key.

However, an advanced antitheft device such as an immobilizer is effective for a vehicle but is not suitable for an object other than the vehicle.

Even with a vehicle equipped with an immobilizer, today there are even tricks to steal a vehicle while driving and steal it with a key. In this way, there is a major drawback that even an advanced device such as an immobilizer is not useful for the technique of stealing the management right of the transmitter of the identification function together. In addition, expensive vehicle thieves have a trick that disables even immobilizers.

The anti-theft device may be invaded by the mechanism and invalidated. The higher the value of an object, the more likely advanced intrusion techniques are used. Anti-theft devices are against the technology to steal, so even if the anti-theft devices are rigorously enhanced to protect, the thief will continue to devise a way to break the defense as long as it is worth it for the thief The weeping phenomenon that happened, and the thief with a high level of intrusion technology had a fateful drawback that it was eventually stolen. There is no anti-theft device equipped with intrusion prevention means that can withstand such intrusion.

Also, there was no anti-theft device that functioned efficiently in the distribution channel from the manufacture of the object to the sale.

Shoplifting in stores has become a major social problem especially during the distribution stage. Although the actual damage caused by shoplifting is large, there is a problem that there is a large amount of expenses for shoplifting countermeasures such as devices for surveillance cameras and anti-theft devices for shoplifting and troublesome operation. There was no anti-theft device that the anti-theft device mounted on the object would prevent shoplifting without attaching the anti-shoplifting device.

Conventionally, as a means of defense against theft that cannot be prevented as described above, it has been generally performed with theft insurance by paying a high insurance premium.

Conventionally, there has been no antitheft device that can effectively reduce these antitheft costs and theft insurance premiums.

There was no anti-theft device that was excellent in use, had a structure that did not require a locking action, and was unable to leave a gap due to forgetting to lock it.

One of the other problems with anti-theft devices is the poor use. In addition to the engine key, a steering wheel lock, a tire lock, an alarm device for detecting an abnormality of the vehicle such as an electrostatic change of the vehicle, a change in impact or a tilt, and an alarm are mounted. However, the more stringent and double these devices are, the more time is required to release and unlock the devices each time the vehicle is used. Similarly, the act corresponding to locking after use has the great disadvantage that it is difficult to use in daily use of the vehicle. Due to the time and effort, forgetting or neglecting to lock the anti-theft device causes a problem of making the anti-theft device open.

The conventional antitheft device does not have an antitheft device that is effective when the object is stolen at any time and in any state.

Furthermore, there is an example in which usability of an object itself equipped with a theft countermeasure device is deteriorated. In the case of a device that locks the calling function of a mobile phone, it is unlocked using a personal identification number, but the object of use form that the use time is relatively short but the use number is high, The anti-theft device with the concept of a general lock or alarm device that is unlocked every time it is used and then relocked after use is not convenient and practical.

Furthermore, the conventional antitheft device has a problem of cost. Due to the high price of the device, it cannot be attached to relatively inexpensive objects. For example, a 20,000 yen anti-theft device is equivalent to 1.0% for a vehicle with a price of 2 million yen, but it is 10% for an object with a price of 200,000 yen, even tens of thousands of yen for headphones. When it comes to stereos, cell phones, and digital cameras, even if a small anti-theft device is made, it cannot be installed cost-effectively. Theft insurance premiums may be much more economical for cheaper objects. There was no cheap anti-theft device that could be used for both expensive vehicles and inexpensive mobile phones and headphone stereos.

Further, the conventional antitheft device may require an installation cost in addition to the cost of the device, and in some cases, a maintenance cost such as a warning monitoring cost may be required. As described above, the more severe the conventional antitheft device is, the higher the total cost becomes, and there is a serious drawback that the object to which the antitheft device is attached is significantly limited in terms of cost.

Headphone stereos, video cameras, mobile phones and other portable electronic devices have a drawback in that they are burdensome in terms of volume and weight and cannot be attached.

Theft frequently occurs in electronic devices such as mobile phones, video cameras, digital cameras, and portable information terminals. Nevertheless, due to the various problems listed above, there is a problem that conventional antitheft devices are not widely used for objects other than vehicles.

Since an IC card is also an object to be stolen, it similarly has a problem of theft and is in a serious situation. IC cards will become increasingly multifunctional in the future. Therefore, once the device is stolen, there is a possibility that it may cause a great deal of damage. Therefore, there is no anti-theft device effective for an IC card even though an anti-theft device for an IC card is required.

In addition, since the thickness of the IC card main body is only about 0.76 mm, there is no antitheft device that can be mounted therein.

Furthermore, as mobile phones and portable information terminals equipped with IC card functions are rapidly spreading in the future, it is also significant that there is no anti-theft device for IC card functions of objects equipped with these IC card functions. It is a problem.

In addition to theft that IC cards are stolen and used, crimes such as unauthorized reading or writing of information on IC cards by a third party with a portable reading / writing device are expected to appear. However, there is no way to deal with crimes using electromagnetic waves.

Traditionally, once an object has been stolen, there is no way to find it or wait for it to be found and there is no way to punish the thief, making the value of the object in the hands of the thief and gaining the thief There was a serious drawback of being left to the thief.

There has been no anti-theft device and anti-theft method that can give the painful punishment of wasting the act of stealing without giving the thief without making the stolen object usable.

  In order to achieve the above object, the present invention provides an electronic circuit for causing an object such as a vehicle, a mobile phone, and an IC card to function normally, an electronic circuit body of the electronic circuit, and a power switch of the electronic circuit body In addition to the power switch, the electronic circuit main body is provided at the central portion of the electronic circuit main body at a position where the signal passing through the central portion is cut off. A second switch, which is a switch mechanism of an A contact to be in a state, and an input device that inputs a predetermined signal such as a password, a password, a fingerprint image, etc., that controls the second switch; An identification device for identifying a connection, a connection instruction device for connecting the second switch only when the identification device identifies an administrator, and a timed device for maintaining the connection state of the second switch for a predetermined time And an electronic circuit comprising a control means having a main component as a main component, wherein when the second switch is not in operation, the electronic switch is held in a state in which it does not move normally even when the power switch is turned on. ,as well as

A safety stop device when the electronic circuit is mounted on a moving body such as a vehicle, and

An electronic circuit characterized by receiving a predetermined signal from a remote-control type external input device; and

Objects such as vehicles, mobile phones and IC cards equipped with these electronic circuits. as well as

An external input device, and an electronic device equipped with the external input device, such as a mobile phone, an information terminal, and an IC card reading / writing device, and

The fact that the anti-theft device is built-in is announced by a notification means such as a mark, a picture, a character, a sound, a video, or the like, or an object notified by the notification means is configured.

As will be apparent from the following description, the present invention has the following effects.

The present invention relates to an electronic circuit for causing an object such as a vehicle, a cellular phone, and an IC card to function normally. In addition to the electronic circuit body of the electronic circuit, the power switch of the electronic circuit body, and the power switch A switch mechanism of an A contact provided at a position where the signal passing through the central portion is cut off at the central portion of the electronic circuit body, which is in a cut-off state when not operating and is connected only when operating The second switch, the input device for controlling the second switch, the input device for inputting a predetermined signal such as a password, a password, and a fingerprint image, the identification device for identifying the input predetermined signal, and the identification The main components are a connection instructing device that connects the second switch to a connected state only when the device identifies an administrator, and a timing device that maintains the connected state of the second switch for a predetermined time. And means, the second when the switch is not operating, an electronic circuit, characterized in that to hold in the state does not move normally even put the power switch.

Therefore, the electronic circuit of the present invention is in a state of functioning normally only when a predetermined signal is input, and the state of functioning normally lasts for a predetermined time, and after the predetermined time passes, The system automatically returns to a non-functional state.

Therefore, an object equipped with an electronic circuit having the function of the anti-theft device of the present invention can be used for a thief by exerting its effect no matter what and when it is stolen.

The above effect will be described below.

First, the effect of the second switch as an A contact switch mechanism will be described.

An electronic circuit provided with a switch mechanism of an A contact at the central portion that is in a cut-off state when not operating does not function normally when nothing is done.

Therefore, the object on which this electronic circuit is mounted can be put into a state where it does not function normally when it is stolen.

Therefore, even if the thief steals, the object cannot be used.

When the administrator uses it, the second switch can be connected for a predetermined time by inputting a predetermined signal such as a password or a password code.

Therefore, for a predetermined time, the administrator can use the object normally by turning on the power switch of the object.

The predetermined time can be set in advance or arbitrarily.

The second switch is automatically shut off when a predetermined time has elapsed after the timing device has timed.

That is, the function of the automatic locking function can be obtained by the combination of the switch mechanism of the A contact and the timing device.

Therefore, after a predetermined time, the object automatically returns to a state where it does not function normally.

In this way, since the shut-off corresponding to the locking action is automatically performed by the timing device, even if it is stolen during this time, the object will not function properly and will move even if the power switch is turned on I can't do that.

However, only the administrator can always enter a state of functioning normally by inputting a predetermined signal.

Therefore, in addition to the effect that the anti-theft device can be easily handled as an anti-theft device that does not require a locking action, an artificial anti-theft device such as forgetting to lock the device or neglecting to set the anti-theft device as in the past. An extremely great effect can be obtained for the anti-theft device that no gap is generated.

Therefore, there is a theft countermeasure device that functions so as to keep the object from moving no matter what time or when it is stolen. Any time is before, during, or after use, and any state is still stolen if it has been locked, even if it has been locked. Say all the conditions that could not be dealt with.

Moreover, the antitheft device of the present invention can maintain the usage of the mounted object. This will be described below.

A second switch is a feature of the structure of the antitheft device of the present invention. The power switch avoids direct involvement of the anti-theft device in order to use the object normally. Another feature of the anti-theft device of the present invention is that a second switch is provided in the central portion separately from the power switch, and the anti-theft function is configured to control the second switch exclusively.

As a result, if the administrator first maintains the second switch in a connected state with a predetermined signal, the object can be freely used with the power switch as before without any involvement in the second switch, that is, the anti-theft device. I did it.

Mobile phones, digital cameras, video cameras, etc. have the feature of usage that the usage frequency is high in spite of the short usage time.

Therefore, the concept of a conventional antitheft method that requires the operation of releasing and setting the antitheft device every time it is used is not practical. It is bothersome and impractical to perform either release or set operation each time it is used. Therefore, once the antitheft device of the present invention is in a state of normal operation, it can be arbitrarily set such as 3 hours or 8 hours, and the object is normally used for a predetermined time without being involved in the antitheft device. be able to. In addition, after the predetermined time, the original state that does not function normally can be automatically returned.

Therefore, while the antitheft device of the present invention is mounted, the original object can be handled.

Therefore, as a theft countermeasure device suitable for a mobile phone, a digital camera, a video camera, etc., an effect that has not been realized so far can be exhibited.

Therefore, the antitheft device of the present invention has an indispensable element as an antitheft device that matches the usage environment of a mobile phone, a digital camera, a video camera, and the like.

According to the present invention, in the electronic circuit according to claim 1, when a predetermined time has passed, the electronic circuit operates before shutting off the second switch. When it is confirmed that the power switch is turned on, a connection signal is transmitted. The electronic circuit according to claim 1, wherein a safety stop device is provided in the control means, the safety stop device interrupting the second switch after the power switch is turned off.

Therefore, when the antitheft device of the present invention is mounted on a moving body such as a vehicle, it is possible to prevent a sudden stop during traveling at the end of a predetermined time.

Therefore, an electronic circuit having the function of the antitheft device can be incorporated in an electronic circuit of a vehicle or aircraft and used as an electronic circuit of the antitheft device.

According to the present invention, the input device and the identification device in the electronic circuit according to claims 1 and 2 are separated from each other, a communication means is provided in the separated portion, and the separated input device is a remote-control type external input device. The electronic circuit receives a predetermined signal from the external input device via the communication means.

Therefore, by separating the bulky input device, an electronic circuit having the function of the anti-theft device of the present invention can be incorporated into an IC card, or can be built into an object in which the input device is difficult to install. An electronic circuit is made.

Therefore, an anti-theft device that can be incorporated in the current technology even in an IC card that has no anti-theft device despite the high necessity of the anti-theft device can be provided.

In the present invention, the electronic circuit according to any one of claims 1 to 3 is mounted as an electronic circuit for causing an object to function normally, or the electronic circuit is integrated into an IC or hidden in an electronic substrate. It is an object such as a vehicle, a mobile phone, or an IC card that is mounted after the intrusion prevention means is applied.

Therefore, the switch mechanism at the center of the electronic circuit can be provided with intrusion prevention means such as being provided in the IC circuit.

Furthermore, if an electronic circuit such as a control means is made into an IC, it can have a structure that cannot be penetrated.

Thus, the antitheft device of the present invention can have a strict intrusion prevention means. Therefore, a theft countermeasure device that can not be broken even by a thief who aims at an expensive passenger car or an organized crime technique aiming at an IC card of a financial institution can be obtained.

The antitheft device of the present invention can have a strict intrusion prevention means due to the following effects.

The main component of the antitheft device of the present invention is an electronic circuit. Therefore, the main components of the antitheft device can be integrated. Therefore, intrusion can be prevented by protecting the IC with the IC package structure. It is difficult to break an IC package without damaging the IC. Even if the IC main body is penetrated and reached, it is impossible for the general technique to penetrate the circuit by the fine structure of the IC main body. Therefore, it is possible to have a strict and advanced intrusion prevention function that prevents third parties from entering by making the electronic circuit of the antitheft device into an IC. Therefore, it is possible to make a theft countermeasure device in which a thief cannot enter.

Therefore, there is an object that can not be moved by the thief and that only the administrator can move normally.

Therefore, it is possible to make a passenger car with a built-in anti-theft device that does not enter a thief aiming for an expensive passenger car.

Therefore, for the same reason, an IC card equipped with a theft countermeasure device that is not intruded can also be made.

The external component according to claim 3, wherein the present invention mainly includes an input device for inputting a predetermined signal such as a password, a password, a fingerprint image, a power source, and a communication means for transmitting the input predetermined signal. An electronic device such as a mobile phone, an information terminal, and an IC card reading / writing device equipped with the input device and the external input device.

Therefore, by having an external input device, the antitheft device of the present invention can be built in today's technology in an IC card having a thickness of only about 0.76 mm.

Furthermore, the multi-functionalization and spread of IC cards can be promoted by the external input device of the IC card antitheft device.

Furthermore, by mounting the external input device on the mobile phone, it is possible to input a predetermined signal from an anti-theft device such as an IC card equipped with the anti-theft device, a motorcycle or a passenger car.

By incorporating an external input device into the IC card read / write device, the IC card can be made to function properly only at the time of payment, thus improving the safety and convenience against theft of the IC card with the anti-theft device. be able to.

According to the present invention, the object according to claim 5 is self-announced by a notifying means such as a mark, a picture, a character, a sound, a video, etc. It is an object notified by the notification means.

Therefore, a thief who knows the characteristics of the antitheft device of the present invention can know that it is useless to steal, and can prevent the object to be notified from being stolen.

  The thief who does not know the characteristics of the anti-theft device of the present invention can know that the notified object cannot be used even if it is stolen. Therefore, it is possible to prevent the object that has been announced thereafter from being stolen.

Below, the other main effects which the antitheft device of the present invention has are listed.

Anti-theft effect in distribution: The anti-theft device of the present invention is built into a product at the manufacturing stage. Therefore, the antitheft device of the present invention is effective from the time of manufacture. Accordingly, it is possible to obtain anti-theft countermeasure effects at all distribution stages from transportation, inventory, and storefront.

Among them, it is particularly effective for shoplifting at stores. Shoplifting can be suppressed by notifying the object that the anti-theft device is installed and that it cannot be used even if it is stolen, by notifying the main body, in-store notifications or in-store broadcasts. Therefore, it is possible to reduce tremendous costs such as actual cameras that are stolen in shoplifting and devices and operations such as surveillance cameras and anti-theft devices to prevent shoplifting, and theft insurance premiums at the time of distribution can be reduced.

Note that the antitheft device of the present invention can incorporate a main part as an electronic circuit in an electronic circuit of an object. Therefore, the object can be mounted regardless of whether the object is large or small, expensive or inexpensive.

Moreover, an object equipped with an anti-theft device that has a wide versatility and can be used easily and has a definite anti-theft effect can be obtained.

In addition, since the main components of the antitheft device of the present invention can be produced by incorporating them in advance in the electronic circuit of the object, mass production becomes possible and the price of the antitheft device can be reduced. Therefore, since it can be already mounted on the object in the manufacturing stage, there is also an advantage that it does not require time and effort for attaching later. Moreover, there is no need for warning monitoring costs and maintenance costs. Therefore, the total cost related to the antitheft device can be reduced. Therefore, a theft countermeasure device that can be mounted on an inexpensive object can be obtained.

Furthermore, the input object, the timer mechanism, the power source, and the like of the identification mechanism of the antitheft device of the present invention often already have an object to be mounted. Therefore, these component parts can be shared. Accordingly, the cost of the antitheft device can be reduced, and the antitheft device of the present invention can be mounted without greatly changing the appearance, arrangement, or structure of the parts already possessed by the object.

In the antitheft device of the present invention, the main components other than the input means are composed of electronic circuits, so that the volume can be reduced to the size of the electronic circuit. Therefore, this electronic circuit can be incorporated into the electronic circuit of the object. Therefore, the antitheft device of the present invention can be mounted on the object with almost no burden of volume and weight. Therefore, the anti-theft device of the present invention can be mounted on a light and small object.

As described above, the antitheft device of the present invention can be mounted even if the object is small, can be mounted on an inexpensive object, and is easy to operate. Therefore, the objects to be mounted are not only mobile objects such as vehicles, ships, and airplanes, but also headphone stereos, video cameras, digital cameras, information terminals including mobile phones, etc. that have not been equipped with anti-theft devices so far. It can also be installed in portable electronic devices, stationary electronic devices such as televisions, video recording devices, household electrical appliances such as washing machines, computers, and office equipment. Therefore, the definition of an object that can be mounted on the anti-theft device of the present invention is an object that may be stolen because it contains an electronic circuit that is indispensable for the object to function and is movable, If it is a target object, it can have wide versatility that the antitheft device of the present invention can be mounted.

An IC card also requires an electronic circuit to operate and can be stolen because it is movable. Therefore, an IC card also applies to the definition of an object on which the antitheft device of the present invention can be mounted. Therefore, a thin and light IC card is also an object on which the antitheft device of the present invention is mounted.

In the future, when the standard of the IC card having a thickness of about 0.76 mm is relaxed, the antitheft device of the present invention can be integrated with the IC card.

Further, in the future, when the thin mounting technology of the input device advances, all the antitheft devices of the present invention can be mounted on an IC card having a thickness of about 0.76 mm.

Today, theft of IC cards can cause enormous damage. Furthermore, in the case of an IC card with a pre-filled amount of money, there was nothing to do if it was stolen. If the anti-theft device of the present invention is installed, the IC itself does not move and cannot be used even if it is stolen. Furthermore, when the reader tries to use it illegally, the reader can sense it and make a reaction such as taking a picture of the user. Therefore, it is possible to obtain a clue for identifying the thief, and it has the effect of restraining the use. Therefore, it is possible to prevent theft by creating an environment in which the thief thinks that the IC card cannot be used even if it is stolen, and that it may be detected if it is used, and the motivation to steal that it is useless or not stolen. Therefore, if it is stolen with a wallet or the like, there is an increased possibility that the thief will throw it away. Therefore, the effect which raises the possibility of collection | recovery can also be anticipated.

Furthermore, as devices equipped with IC card functions are widely used in mobile phones and portable information terminals, the present invention is applied to both mobile phones and portable information terminals and IC card mechanisms or IC card mechanisms. It is possible to cope with theft by installing the antitheft device.

Furthermore, a new form of theft is expected to occur in the IC card. Even if the card itself is not stolen, there is a risk that the information on the IC card is read and stolen if the thief approaches with a portable card reader / writer. Since the antitheft device of the present invention can prevent the electronic circuit body of the IC card from moving, it can cope with crimes using electromagnetic waves on such an IC card.

Therefore, if the IC card itself does not have an effective anti-theft function, it is possible to promote widespread use by installing the anti-theft device of the present invention.

An anti-theft method capable of giving a painful punishment of not wasting the thief without wasting the thief without wasting the thief by not letting the thief use the stolen object even if it was stolen, and The purpose is to provide anti-theft devices

An object equipped with the antitheft device of the present invention can be equipped with an antitheft device of an existing method or another method. Therefore, by using a plurality of anti-theft devices including the anti-theft device of the present invention in combination, the anti-theft effect of the existing or other anti-theft devices and the non-theft anti-theft effect of the anti-theft device of the present invention. A synergistic effect can be obtained.

As described above, when the electronic circuit with the anti-theft device of the present invention is used as the anti-theft device, it is possible to obtain many effects that cannot be obtained by the conventional anti-theft devices and anti-theft methods.

An object equipped with the antitheft device of the present invention cannot be used even if it is stolen. Therefore, it is useless to steal. Therefore, by letting the thief know the effect of the anti-theft device and the object equipped with the anti-theft device, it acts on the motivation of the thief to steal itself and leads to a stealing action. Has no effect. Therefore, the conventional antitheft device that protects against the theft is partly freed from pretending to have to continue to develop an antitheft device that always exceeds the clever trick of the thief.

Here, the terms used in this specification are defined as follows.

As used herein, an object is defined as an object that requires an electronic circuit to function normally and can be stolen because it is movable, such as a vehicle, a mobile phone, and an IC card. To do. The defined objects are as shown in the list of FIG.

The electronic circuit main body used in this specification refers to an electronic circuit main body that is indispensable for the functioning of an object. If it is a vehicle, it is an engine control circuit, if it is a mobile phone, it is a transmission / reception circuit or a screen display circuit. If it is a digital camera, it is an electronic circuit for imaging or an electronic circuit for driving a monitor. If there is, it is a circuit of the IC itself or a circuit for communication, and includes peripheral electronic circuits indispensable for the electronic circuit to function.

The power switch for an object is a general power switch that a user turns on when using the object. If the object is a vehicle, the engine key is equivalent, and if it is a mobile phone or a digital camera, a power button is an example. However, the IC card which is the object of the present invention does not have a power switch exposed to the outside.

The central portion is a circuit portion through which a signal and electric power for normally moving the electronic circuit main body pass, and when cut off, the electronic circuit main body is in a state where it does not function normally.

The shut-off unit is intended to shut down the signal and power passing through the central part and stabilize the electronic circuit body in a state where it does not function normally, and is a signal or power shut-off means provided in the central part. . Therefore, the interruption used in this specification is not limited to mechanical interruption of a circuit. The blocking includes means for keeping the electronic circuit main body from moving normally by blocking, attenuating, or disturbing signals of electronic components such as semiconductors, resistors, and filters. Since the signal of interest may be light, means for blocking light is also included in the blocking of the present invention. As the structure of the blocking part, a non-contact circuit such as electrically blocking or attenuating a signal is practical. Therefore, in the drawings of the present specification, the blocking portion is expressed in a mechanical notch, but this is an expression for emphasizing and explaining the role of the blocking portion.

For vehicles that are not functioning properly, functions normally, and functions that do not function normally, the vehicle, mobile phone, IC card, etc. It means that it does not make a call, the monitor does not appear, it cannot be settled if it is an IC card, or it is as if it cannot be repaired or used unless it is repaired. A state that does not function properly as a product is defined as a state that does not function properly. A general instruction manual that describes the state of a symptom that requires a failure or repair.

On the other hand, if it does not function because the key is missing, the fuel is dead, or the battery is exhausted, it will function if the key is inserted, the fuel is replenished, or the battery is charged. Those states that do not normally function are not normally functioning states as used herein and are clearly distinguished from states that do not function normally.

  The administrator in this specification refers to the person who purchases and uses the target object, the family of the person who is authorized to use the object, and the person who has management responsibility in the distribution stage retroactively at the time of manufacture before sales. , Say the rightful manager from time to time, such as maintenance and repair technicians.

The predetermined signal 14 referred to in this specification is a signal such as a code such as a code number or code, a signal of an image such as a fingerprint or an iris image, a face shape or a shape of a subcutaneous blood vessel, a voice print or DNA. Say a manager specific signal to identify the manager.

In addition, when the predetermined signal itself is stored in an IC chip or an IC tag and used as a predetermined signal using a device that transmits a personal identification number unique to an administrator, the chip is embedded in the body, or from a body such as a ring. It is a condition that the administrator occupies the predetermined signal to the last, such as taking measures that do not function when the user does not move away from the body.

Therefore, the input device 11 for the predetermined signal 14 is a numeric or character input button if the predetermined signal is a password or a password, a fingerprint sensor if it is a fingerprint, or a blood vessel image of the hand. The blood vessel image sensor is an input device corresponding to a predetermined signal, such as an image sensor in the case of an iris pattern or a face. It also includes an input device for identification means to be developed in the future.

The predetermined time mentioned in the present specification is the length of time for which the object keeps moving normally by the antitheft device of the present invention, and is in units of seconds such as 30 seconds or 60 seconds, 3 minutes, 10 minutes. -A minute unit such as 30 minutes, a time unit such as 3 hours and 12 hours, a daily unit such as 7 days and 30 days, a week unit, a month unit, and a year unit are set in advance. It is. In addition, the definition also includes a case in which a normal date and time is specified, such as a holiday day or an evening every morning. The length and date when using the anti-theft device may be set in advance, selected from several preset values, or may be arbitrarily set by the administrator each time.

Hereinafter, the present invention will be described in detail with reference to the best mode for carrying out the invention shown in the drawings.

1 to 60, the basic part for implementing the antitheft device of the present invention will be described along the claims, and the embodiments of the present invention will be described with reference to FIG. 61 and subsequent figures.

1 to 4 illustrate a basic portion of the antitheft device of the present invention that makes an object not function normally.

FIG. 1 is a schematic diagram of an object such as a vehicle, a mobile phone, and an IC card and an electronic circuit. The object 1 is schematically represented by a dotted frame, the electronic circuit 2 of the object 1 having the power switch 3 is represented by a solid line, and the central part 5 of the electronic circuit body 4 is represented by a single lead wire. The object 1, the electronic circuit 2, the power switch 3, the electronic circuit body 4, and the central part 5 of the object are schematically illustrated. If the power switch 3 is turned on, the object can be moved.

FIG. 2 is an electronic circuit in which a blocking portion 6 for blocking the central portion 5 is provided in the central portion 5 of FIG.

This is because the blocking unit 6 prevents the thief from using the object when the object containing the electronic circuit is stolen.

FIG. 3 shows that when the electronic circuit 2 is in the state of FIG. 2, the electronic circuit body 4 remains in a state in which it does not function normally due to the blocking unit 6, and the object can function even if the power switch 3 is turned on. Indicates that it cannot be done.

The electronic circuit body 4 provided with the blocking part 6 in the central part 5 is an electronic circuit diagram 2 in which the basic state does not function normally, and the thief does not use the object when stolen. It is the electronic circuit explaining the basic means for implementing this antitheft device.

FIG. 4 shows an example in which the blocking unit 6A is provided in a place in series with the power switch 3A. Even in this case, the electrical purpose of interruption can be achieved. However, when the object 1A is a passenger car, a motorcycle, or the like, it cannot be used as the electronic circuit 2A of the anti-theft device because this method easily enters the blocking portion. However, if the electronic circuit body 4A is contained in a housing that is difficult to open, or if measures such as an electronic circuit board structure that is difficult to reach are taken, the degree of difficulty in reaching it will be reduced. Therefore, the anti-theft device is effective.

As can be seen from FIGS. 2 and 4, the blocking portion can be provided in a wide range of the central portion from the portion near the power source and the power switch in the central portion of the electronic circuit body to the inside of the IC. Where it is provided may be determined depending on the object, such as the severity of intrusion prevention and the balance of productivity. Therefore, although the interruption | blocking part demonstrated in the figure of this specification is demonstrated using the example of FIG. 2 in many cases, a figure does not prescribe | regulate the installation place of an interruption | blocking part.

The reason why the blocking part 6 is provided in the central part 5 of the electronic circuit main body 4 is that in addition to making the electronic circuit not function normally, it is possible to take effective intrusion prevention means. The IC chip itself is protected by a robust IC package by providing a central part with a blocking part inside the multilayer substrate of the electronic circuit body or by making the central part with a blocking part an IC. For example, the IC structure itself has an intrusion prevention means that prevents the intrusion, such as the fine structure prevents the intrusion.

FIG. 5 to FIG. 12 explain that a switching mechanism of an A contact is provided in the blocking part.

FIG. 5 is a schematic diagram of the electronic circuit 2 in which the blocking portion is an A-contact switch. The power switch 3 that the electronic circuit body 4 originally has is counted as the first, and the switch of the A contact provided in the shut-off portion is called the second switch 7 and will be described below.

The electronic circuit having the blocking unit described with reference to FIG. 2 keeps the object 1 from moving normally, and can be prevented from being used by a thief even if it is stolen. Therefore, when the administrator uses the object, the blocking unit 6 may be connected. For this purpose, the second switch shown in FIG. 5 is a means for switching the electronic circuit into two states, that is, a state in which the electronic circuit does not move normally and a state in which the electronic circuit moves normally. However, since it is necessary to keep the original unusable state when not in use, the second switch is an A-contact switch mechanism.

This structure in which the second switch is an A-contact switch mechanism is an important basic structure of an electronic circuit having the function of the antitheft device of the present invention.

As can be seen from FIG. 5, the object 1 does not move normally as long as the second switch 7 is cut off. Only when the second switch 7 is in the connected state, the power switch 3 can work effectively to make the object 1 move normally.

FIG. 6 shows an example in which a second switch 7A is provided in a place in series with the power switch 3A. It is the example which made the interruption | blocking part 6A of FIG. 4 the switch of A contact. It expresses that where the position of the second switch 7A in the electronic circuit main body 4A is provided may be determined by the object 1A in consideration of the severity of intrusion prevention and productivity. Therefore, in many cases, the second switch described in the drawings of this specification is described using the example of FIG. 5, but these drawings do not define the installation location of the second switch.

FIG. 7 illustrates that the switch mechanism of the second switch is an A-contact switch, and in addition, expresses that the structure of the second switch 7 of FIGS. 5 and 6 is the structure of an A-contact switch. FIG. However, it is rare to actually take such a mechanical structure, and it often takes the form of a contactless A-contact switch mechanism as described below. The structure of the A-contact switch used in this specification is a state in which the shut-off unit 6 is shut off when the switch is not operating, and the shut-off unit 6 is connected only when the switch is operating. Defined as a switch. Therefore, only when the second switch 7 is operating, the electronic circuit 2 continues to operate normally.

Next, an example of an A contact switch mechanism will be described with reference to FIGS. As described above, the second switch 7 is not limited to a mechanical switch, but takes the form of a non-contact switch that is incorporated in an IC circuit or disposed in an electronic board, and is more often used. That is, the second switch 7 exists in the electronic circuit 2 in various forms as a contactless switching mechanism having a switching function of an A contact.

FIG. 8 shows a first example of the second switch. The second switch 7 is a contactless A-contact switch mechanism 31 including a PNP transistor 33, a gate drive circuit 35, and a gate control circuit 36. It is an example. The antitheft device of the present invention can be integrated with the electronic circuit body 4 of the object 1 by making most of the electronic circuit. If the electronic circuit body 4 is an IC, most of the electronic circuit of the antitheft device of the present invention can be integrated with the electronic circuit body 4 as an IC. The IC can prevent intrusion and can be a cheap anti-theft device due to mass production effect. Therefore, it is desirable that the object is an IC if it is a mass-produced product. In that case, a contactless switch mechanism is required instead of a mechanical switch mechanism. Examples thereof are shown in FIGS.

FIG. 9 shows a second example of the second switch, which is an example of an A-contact switch mechanism 31A using an NPN transistor 33 instead of the PNP transistor 32 of FIG.

FIG. 10 shows a third example of the second switch, which is the second switch 7 composed of the A-contact switch mechanism 31B using the thyristor 34. However, when the thyristor 34 is used, it is necessary to provide another blocking means in addition to issuing a signal for maintaining a normal state. Further, in the case of a thyristor, since the connection state can be maintained by itself, It may give the thief a chance to enter. Therefore, when a strict intrusion prevention mechanism is provided, there is a drawback that the circuit of the switch mechanism becomes complicated, such as the blocking means must be protected by the intrusion prevention mechanism.

In addition, since atomic switches that are expected to be put into practical use in recent years are fine and can shut off circuits, they are advantageous as electronic components used for the A-contact switch mechanism 31 in IC circuits.

Note that the blocking unit includes means for keeping the electronic circuit main body from moving normally by blocking, attenuating, or disturbing signals of electronic components such as semiconductors, resistors, and filters. Therefore, these electronic components are normally in a state of being cut off, attenuated or disturbed, and have a function of an A-contact switch mechanism that is in a normal state only when operating.

In addition, although the place to cut off is the central part through which the main signal of the electronic circuit main body passes, the purpose of the interruption is to stop the main function of the electronic circuit main body. It is more efficient to select the key points. For example, if a DC current such as a power supply or a bias current flows, a cutoff circuit can be created with a transistor adapted to the signal, but in the case of AC, multiple transistors are required, or a high frequency is dedicated There is a disadvantage that the number of problems that need to be solved increases, such as the need for transistors.

In addition, although the figure demonstrates in the location of one interruption | blocking, the case where several places are interrupted | blocked is included. Therefore, it includes a case where a plurality of the second switches are arranged in accordance with the locations to be shut off. An example having a plurality of second switches at a plurality of locations in the central part of the electronic circuit body is shown in FIGS. FIG. 11 shows a case where two switches are provided in a series of A contact point switch mechanisms, and FIG. 12 shows a case where a plurality of switch mechanisms are provided.

The basics of the electronic circuit having the function of the antitheft device of the present invention will be described with reference to FIGS.

FIG. 13 is a schematic diagram of the electronic circuit of claim 1. This is an electronic circuit 2 provided with a control means 10 for controlling connection and disconnection of the second switch 7. The control means 10 is a fundamental part of the antitheft device of the present invention described later. The electronic circuit 2 is characterized in that it is not the power switch 3 but the second switch 7 that the control means 10 controls connection and disconnection.

By controlling not the power switch 3 but the second switch 7 which is a switch mechanism of an A contact, a theft countermeasure device that does not impair the method of using the object is realized.

FIG. 14 is an example in which the installation location of the second switch 7A and the control means 10A in FIG. 13 is provided near the power switch 3A. Where the position of the second switch 7A in the electronic circuit body 4A is provided may be determined depending on the object, such as the severity of intrusion prevention and the balance of productivity. Therefore, the positions of the second switch 7 and the control means 10 described in the drawings in this specification are often described using the example of FIG. 13, but the figure shows the second switch 7 and the control means 10. The position of is not specified.

FIG. 15 is a diagram showing the main components of the control means 10 for controlling the second switch 7, and the components will be described below.

The control means 10 is a device that controls the second switch as described above, and includes the input device 12, the identification device 14, the time limit device 16, and the connection instruction device 17 as main components. As can be seen from the description, each of the components of the control means is not special but is general.

The input device 12 is a device for inputting a predetermined signal 13. If the predetermined signal is a password, it has a numeric button, if it is a password, it has a character button, and if it is a fingerprint image, it has a fingerprint sensor. For example, it takes a form corresponding to a predetermined signal type. Therefore, there are various forms according to the type of the predetermined signal.

Further, there may be an operation button or an operation unit for changing registration of a predetermined signal or changing a predetermined time. In addition, an input device switch 11 for activating the input device 12 or the control means 10 is provided. However, this switch is not required when always waiting for input.

The identification device 14 is a device that collates and identifies the predetermined signal 13 input to the input device 12 with a predetermined signal registered in advance. If the predetermined signal 13 is correct after collation, a Yes signal is generated. In the present specification, a signal emitted from the identification device 14 when Yes is referred to as an identification signal 15 for convenience. The identification device 14 has a predetermined signal and a storage device corresponding to registration and change of the predetermined signal 13.

The connection instructing device 17 that has received the identification signal 15 issues a connection signal 18 that puts the second switch 7 in the connected state, and puts the second switch 7 in the connected state. The connection state of the second switch is maintained when the connection instruction device continues to transmit the connection signal or when the second switch side continues the connection after receiving the connection signal. When the predetermined time has passed, the continuous signal is stopped in the former case, and the second switch is returned to the shut-off state by the stop signal in the latter case.
However, the connection instructing device does not necessarily exist alone and may be associated with the identification device, the timed device, or the second switch, and therefore does not necessarily have to be formed as a single device.

The timing device 16 keeps the second switch in the connected state for a predetermined time, and the important function of the electronic circuit of the present invention for automatically returning the second switch to the shut-off state after the predetermined time elapses. It is an important device that fulfills

The position of the timing device is displayed below the connection instruction device in FIG. 15, but the second switch when a predetermined time elapses, such as a position between the identification device and the connection instruction device, or a position parallel to the connection instruction device. The position is not limited as long as it is a position necessary for automatically returning to the shut-off state. If the object originally has a clock function, the efficiency of the parts can be improved by using the clock signal of the object. However, when the clock signal of the object is used, intrusion from the clock function can be prevented by taking intrusion prevention measures that do not allow the clock signal to enter. In addition, when a predetermined signal is input and identified within a predetermined time, an addition method such as zero addition, which starts a new time measurement, adds to the remaining time, or does nothing, is performed in advance. It is good to decide.

However, in the following description, there is a schematic diagram in which these components are expressed as independent circuits in the present specification, but these expressions are for the purpose of explaining the role of the device, and the position and size. The figure does not prescribe. The identification device, the timed device, and the connection instruction device do not have to be arranged in order in the control means, and any two of the identification device, the timed device, and the connection instruction device are integrated, or the whole In some cases, each of them may be dispersed in an electronic circuit, for example, integrated with a second switch, or integrated with a timepiece device of an object. The same applies to the case where the safety stop device according to claim 2 is added to the components of the control means.

By providing this control means 10, the electronic circuit 2 of claim 1 continues to operate normally for a predetermined time only when a predetermined signal 13 is input, and normally after a predetermined time has passed. It operates to automatically return to a non-moving state. This operation is an important basic operation of the antitheft device of the present invention.

Note that the power for driving the control means 10 is supplied from the power supply device of the object, and is not expressed in each drawing.

Similarly, the timepiece device is not represented each time in the figure as a time signal itself or a clock signal such as a clock signal is supplied from the timepiece device of the object.

However, for an object that does not have a power supply device or a clock device that moves the control means, such as an IC card, the power supply device and the clock device are indispensable and are represented in the figure.

Further, as described in the sixth aspect, in the case of an IC card or the like, the input device or a part of the input device may be separated from the object body. In that case, an electronic circuit provided with a control means for separating the input device or a part of the input device is also included.

FIG. 16 is a flowchart of the basic operation of the control means according to claim 1 of the present invention. A predetermined signal is input to the input device from the start. A predetermined signal is transmitted from the input device to the identification device. A predetermined signal is collated by the identification device. Only in the case of Yes, the connection instruction device issues a connection signal to the second switch for a predetermined time. When the predetermined time is over, the connection instructing device stops transmitting the connection signal. finish. It is.

Therefore, the second switch 7 under the control of the control means operating as shown in the flowchart of FIG. 16 is connected only when a connection signal is issued. Therefore, the electronic circuit 2 continues to operate normally only while the second switch 7 is connected.

Next, the basic operation of the control means will be described with reference to FIGS. The electronic circuit of the present invention can be better understood when read in light of the flowchart of FIG.

FIG. 17 shows the control means 10 including the input device 12, the identification device 14, the time limit device 16, and the connection instruction device 17.

FIG. 18 illustrates the operation of the control means 10. A switch 11 of the input device is turned on to input a predetermined signal to the input device. The switch of the input device is a switch for starting the input device, but this switch is not necessary when the input device is always in input standby. The input predetermined signal 13 is transmitted to the identification device 14 and identified. If the predetermined signal is correct, the identification device 14 issues an identification signal 15 to the connection instruction device 17. The connection instructing device 17 that has received the identification signal 15 issues a connection signal 18 to the second switch 7 to place the second switch 7 in the connected state. In this state, the electronic circuit moves normally. At this time, the timing device 16 starts measuring a predetermined time.

FIG. 19 illustrates the operation of the control means within a predetermined time. The timing device 16 is measuring a predetermined time, and during this time, the connection instruction device 17 continues to issue the connection signal 18 to the second switch 7 to keep the second switch 7 connected. Therefore, the electronic circuit continues to operate normally. The input device 12 and the identification device 14 have stopped their roles.

When the time limiter 16 finishes counting the predetermined time, the connection instruction device 17 stops, so the connection signal also stops. Therefore, the second switch is cut off and the electronic circuit returns to a state where it does not operate normally. That is, it automatically returns to the state of FIG.

  FIG. 20 is a time chart showing the operation of the control means, the second switch, and the object described above. When the predetermined signal is collated, the second switch is connected so that the object moves normally, and the timed device automatically returns to the state where it does not move normally after a predetermined time.

Here, how to output the connection signal 18 will be described. The connection signal 18 is a signal that keeps the second switch 7 connected for a predetermined time. Therefore, the connection signal 18 uses a continuous start signal and a continuous end signal as shown in time chart example 2 of the operation of the antitheft device of the present invention in FIG. There is also.

In this case, the second switch moves to the connection state by the connection start signal, maintains the connection, and returns to the cutoff state when the connection end signal is received. Further, as shown in time chart example 3 of the operation of the antitheft device of the present invention in FIG. 22, the time limit device 16 is provided on the second switch 7 side using only the connection start signal, and the second switch 7 after a predetermined time. There are a variety of ways to shut off the switch on the side.

However, when a signal for blocking is used, if the blocking signal is not transmitted or if the blocking signal receiving device or the receiving device does not function, the second switch 7 is not blocked and remains connected. The possibility increases. Therefore, a supplementary device is necessary. Therefore, the connection signal 18 can be a simpler device if a continuous signal such as a continuous signal or an intermittent signal is used.

Further, referring to FIG. 22, the connection instruction device and the connection signal are unnecessary, and the same effect can be obtained only by the identification device and the identification signal instead. However, it actually plays a role of an instruction and connection signal for the second switch.

Thus, the main components of the control means of claim 1 are the input device, the identification device, the connection instruction device, and the timing device, but the location and order of the electronic circuit are not specified by the figure. The same applies to the control means corresponding to claim 2 described in the next section.

As another method of using a timed device, in the above description, it is described as a device in which a predetermined time elapses regardless of whether the object is used or not. The anti-theft device of the present invention also includes a time limit device that reduces the predetermined time by the amount of time.

Note that the electronic circuit of the antitheft device of the present invention requires a power supply device and a clock device, but both the power supply device and the clock device are shown in the figure as being already possessed by the object on which the antitheft device is mounted. Not. However, in an embodiment for an IC card having the anti-theft device of the present invention, which will be described later, the IC card has neither a power supply device nor a clock device.

Claim 2 will be described with reference to FIGS.

FIG. 23 is a diagram illustrating the control means 10 in which a safety stop device 19 is added to the components of the control means 10 of claim 1. As a result, the main components of the control means 10 are the input device 12, the identification device 14, the time limit device 16, the connection instruction device 17, and the safety stop device 19.

FIG. 24 is a flowchart of the basic operation of the control means with the safety stop device, and is a flowchart of the basic operation of the electronic circuit equipped with the control means according to claim 2 of the present invention. An operation in which a safety stop device is added to the flowchart described in FIG. 16 is performed. A predetermined signal is input to the input device from the start. A predetermined signal is transmitted from the input device to the identification device. A predetermined signal is collated by the identification device. Only in the case of Yes, the connection instruction device issues a connection signal to the second switch for a predetermined time. When the predetermined time is over, the safety stop device confirms that the engine is stopped. In No, it judges that it is driving | running and a connection instruction | indication apparatus continues sending a connection signal. The safety stop device confirms that the engine is stopped by performing a predetermined time interval such as 3 minutes or 10 minutes, monitoring a signal that the engine is running, or waiting for receiving an engine stop signal. There is a way to keep it. Only when the engine stop is Yes, the connection instruction device stops transmitting the connection signal. finish. It is.

Therefore, the second switch under the control of the control means operating as shown in the flowchart of FIG. 24 is connected only when a connection signal is issued. Thus, the electronic circuit remains in a normally functioning state only while the second switch is connected.

FIG. 25 is a schematic diagram of the electronic circuit of claim 2. The relationship of the control means 10A with the safety stop device 19 which controls connection and interruption | blocking of the 2nd switch 7B and the 2nd switch 7B of the electronic circuit main body 4B is represented.

FIG. 25 is a schematic diagram representing the electronic circuit 2B including the control means 10A together with FIG. 13 described in the first aspect. As described in the operation of the control means 10A, the electronic circuit 2B maintains a normal functioning state for a predetermined time when a predetermined signal is input, and does not function normally after a predetermined time. It has the function of automatically returning to Therefore, this electronic circuit 2B has a function as a theft countermeasure device in which only an administrator having a predetermined signal can function normally. Therefore, the electronic circuit 2B provided with the second switch 7B under the control of the control means 10A becomes an electronic circuit 2B with a built-in antitheft device. Therefore, if the electronic circuit 2B is incorporated, the object 1B becomes the object 1B with the antitheft device.

The schematic diagram example 1 of the electronic circuit of claim 4 in FIG. 26 represents the control means 10A with the safety stop device 19 attached thereto.

In the control unit 10 described so far, all parts other than the input unit of the input device are electronic circuits. Moreover, it is often mounted integrally with the main electronic circuit of the object. Therefore, it does not necessarily form a certain shape as an antitheft device on the electronic board. Accordingly, in FIGS. 17 to 19 and FIG. 26 described in the section of claim 3, the input device 12, the identification device 14, the time limit device 16, the connection instructing device 17, and the safety stop device which are main components of the control means 10 are used. 19 is expressed separately so that each has a shape, but it is divided only to explain the functions of the constituent elements, and the figure does not prescribe the actual size or positional relationship of the electronic circuit. . The same applies to the following drawings.

Therefore, in the control means, as shown in the schematic diagram example 2 of the electronic circuit of the control means in FIG. 27, the timing device is close to the second switch, the identification device or the input device side, or FIG. As shown in schematic diagram example 3 of the electronic circuit of the control means, a circuit that connects the second switch when the identification device identifies and shuts off at the end signal of a predetermined time, but in this case, the identification device instructs the connection Has the function of the device. The schematic diagram example 4 of the electronic circuit of the control means in FIG. 29 is integrated with the drive circuit of the second switch and the connection instruction device, or the schematic diagram example 5 of the electronic circuit of the control means in FIG. All the control means other than the input device may be integrated with the second switch, or the circuit of the constituent elements may intermingle with each other, such as being mixed with the clock device or power supply device originally provided with the object, The figure does not prescribe the position, shape, order, or location of the circuit of each component, such as being distributed above or partially or entirely incorporated in an electronic circuit on the object side.

Based on the above assumptions, in the schematic diagrams of the circuits used from this section onward, the control means 10 is represented by a single solid line frame, and when a specific component in the control means is described, Only the components of are expressed.

Next, FIG. 31 to FIG.

The main target object as claimed in claim 3 is an IC card. In addition, large objects such as passenger cars, motorcycles and ships are also targeted.

Since the object such as a vehicle is large, the electronic circuit main body and the input device may be distant from each other and the control means may not be integrated. Regardless of this, there are advantages such as having an input device and eliminating the need to provide an input device near the dashboard or instrument panel.

On the other hand, in the case of a small and thin IC card, since the IC card body is as thin as about 0.76 mm, it is impossible to incorporate an electronic circuit body including all of the input devices with today's built-in technology. However, even if it can be built in, there is a problem that the manufacturing price of the IC card increases.

Therefore, in the case of an IC card, a communication means for disconnecting the input device or at least the input portion of the input device from the control means of the antitheft device of the present invention from the IC card body and receiving a predetermined signal from the outside instead is provided. Then, the anti-theft device of the present invention can be built in an IC card having a thickness of about 0.76 mm with today's built-in technology. Thus, an inexpensive IC card with a built-in antitheft device can be obtained.

In the case of IC cards with restrictions on the place where they can be built, rather than having an input device outside, the installation restrictions of the input device can be reduced and the operation functions can be easily expanded and enhanced. It is possible to promote the multi-functionalization and popularization of IC cards, such as facilitating adaptation.

The separation type of the control means of FIG. 31 explains that the input device is separated from the control means of the main components of the control means of FIG. 15 to form an external input device, and FIG. 32 is a control means with a safety stop device. The separation type of FIG. 23 explains that the input device is separated from the control means of the constituent elements of the control means with the safety stop device shown in FIG. A communication means is provided in the separated part.

The electronic circuit 2C controlled by the control means 10C having the external input device 20 in FIG. 33 is a schematic diagram in which the external input device 20 is separated by using the schematic diagram of the electronic circuit in FIG. Communication means 21 is provided between the separated external input device 20 and the control means 10C on the object 1C side.

The method of sending the predetermined signal 13 from the external input device 20 to the control means 10C on the object 1C side is performed via the communication means 21. The communication means 21 may have a mechanism according to a commonly used remote control device or a bidirectional remote control device. The communication means 21 is a transmission unit 22 on the external input device 20 side, and a reception unit 24 on the object 1C side. Depending on the transmission method of the communication means 21, an antenna is provided for radio waves, a light emitting portion and a light receiving portion are provided for light, a connection terminal is provided for a contact type, and there is a case of wired connection. However, since the communication means 21 has a risk of intrusion that the predetermined signal 13 is eavesdropped, the transmission unit 22 and the reception unit 23 are operated close to each other, communication is performed using weak electromagnetic waves, secret communication, It is advisable to take measures to prevent intrusion, such as using light or connecting them directly with a contact.

FIG. 34 is a diagram in which the predetermined signal 13A is input to the electronic circuit 2C of FIG. 33 to make the electronic circuit 2C move normally. A predetermined signal 13 </ b> A input from the input unit 30 of the external input device 20 is transmitted from the transmission unit 22 by an electromagnetic wave 26. If the identification device 14B identifies and corrects the predetermined signal 13A received by the receiving unit 24, the identification signal 15A is issued, the connection instruction 18A is transmitted to the connection instructing device 17B, and the second switch 7C is brought into the connected state, thereby causing the electronic circuit 2C. To make it move normally.

FIG. 35 illustrates a predetermined time state of the operation of the electronic circuit controlled by the control means having the external input device. This is a time after a predetermined time in the state after FIG. At this time, the time limit device 16B and the connection instruction device 17B are operating in the control means 10C.

The IC card from which the input device is separated will be specifically described in the section of the embodiment.

Claim 4 will be described with reference to FIGS.

A fourth aspect of the present invention is an object on which the electronic circuit of the present invention is mounted as an electronic circuit equipped with an antitheft device. That is, it is an object equipped with a theft countermeasure device.

A feature of the antitheft device of the present invention is that the object of the action corresponding to the unlocking of the antitheft device is not the power switch but the second switch. Therefore, the unlocking action is not the purpose of using the object, but is characterized by the unlocking action for making the object move normally.

The basics of the operation of the antitheft device when incorporated in the electronic circuit object of claims 1 to 3 are the same. Therefore, the description of the operation will be focused on the basic operation of the anti-theft device, and each specific operation will be described in the section of the embodiment.

FIG. 36 is a flowchart showing the basic operation of anti-theft for an object incorporating the anti-theft device of the present invention. start. A predetermined signal is input by an input device. The identification device compares and identifies a predetermined signal. Only when the collation of the predetermined signal is Yes, the object is brought into a state of functioning normally for a predetermined time. The object is maintained in a normally functioning state for a predetermined time. When the predetermined time is over, the object is returned to the original non-functional state. End. It is.

FIG. 37 is a time chart showing the operation of the object incorporating the antitheft device of the present invention. A switch of the input device is turned on to activate the input device, and a predetermined signal is input. The predetermined signal is collated by the identification device. When the predetermined signal is verified, the connection instruction device issues a connection signal. The second switch is connected by the connection signal. At this time, the timing device starts measuring a predetermined time.

As a result of the above, the object that has been unusable until now changes to a usable state. At this time, the object remains in a state where it can be freely used at any time. It can be used by turning on the power switch of the object, and it can be turned off when the use is over. When the predetermined time has passed, the timing device works to shut off the second switch. Therefore, the object automatically returns to a state where it cannot be used.

That is, the anti-theft device of the present invention has a great feature that not only makes the object move normally when used, but also keeps the object in a usable state, that is, a state that moves normally for a predetermined time. .

38 to 39, the operation of the anti-theft of an object incorporating the anti-theft device of the present invention will be described.

FIG. 38 shows the target 1D when the target 1D does not move normally, that is, when the administrator does not use it. Since the switch 11C of the input device is cut off and the entire control means 10D is not operating, the second switch 7D is in the cut-off state. Therefore, the electronic circuit body 4D does not move normally, and the object 1D does not move normally. At this time, even if the power switch 3D is turned on, the object 1D does not move. Therefore, even if it is stolen at this time, the thief cannot use it. The components are indicated by dotted lines in the control means 10D in the following diagram for the purpose of explaining the operation of the components below, and the location and size of each component are specified. It is not a thing.

FIG. 39 corresponds to the case where the administrator makes the object 1D usable. The input device switch 11C is turned on, and a predetermined signal 13B is input to the input device 12B. The input predetermined signal 13B is sent to the identification device 14C. The identification device 14C identifies the predetermined signal 13B, and issues an identification signal 15B to the connection instruction device 17C only when Yes. Upon receiving the identification signal 15B, the connection instructing device 17C issues a connection signal 18B to the second switch 7D, and puts the second switch 7D into a connected state. Since the second switch 7D has started the connection state, the electronic circuit body 4D also starts to move normally. At this time, the time limiter 16C starts measuring a predetermined time.

FIG. 40 shows a state where a usable state is maintained. Only the timing device 16C and the connection instruction device 17C of the control means 10D are in operation and continue to issue the connection signal 18B to the second switch 7. The second switch 7D keeps the connection state and makes the electronic circuit body 4D move normally. This state is when the antitheft device of the present invention is moving the object 1D normally. This state is maintained for a predetermined time that is arbitrarily set in advance or can be set each time.

FIG. 41 shows a state where the power switch 3D is turned on and the object 1D in the state of FIG. 40 is being used. During the predetermined time, if the power switch 3D is turned on, the object 1D can be freely used at any time. When the use is over, it is only necessary to turn off the power switch 3D. This action is the same as a normal action not related to the anti-theft device. As described above, the antitheft device of the present invention can be used as many times as usual within a predetermined time. This feature is effective as an anti-theft device that is easy to use for mobile phones, digital cameras, video cameras, etc., which tend to be used frequently for a short time. A thief can only be used if he / she stole in this state. However, after a predetermined time, it cannot be used automatically.

FIG. 42 shows a state when a predetermined time has passed. The timing device 16C finishes timing and stops the connection signal 18B of the connection instruction device 17C. Accordingly, the second switch 7D returns to the cutoff state. The object 1D also returns to a state where it does not function normally. Therefore, it cannot be used even if the power switch 3E is turned on as shown in the figure, and it cannot be automatically used even if it is used. A major feature of the antitheft device of the present invention is that it automatically and forcibly returns to this state. In the case of continued use, the input device 12C only needs to input a predetermined signal 13B, which is extremely simple and easy for the administrator. In a case where the usable state is continued, a method of inputting the predetermined signal 13B when the usable state is available is simple. In that case, the time limiter 16C may be set to add a predetermined time or start a predetermined time from that point. Even if the thief steals and uses it in the state of FIG. 41, it cannot be used from this point. Thus, the time limit device 16 is an important element and an indispensable element of the antitheft device of the present invention for performing an action corresponding to the locking of the antitheft device.

However, for objects such as vehicles and computers that are dangerous or undesirable to stop suddenly during use, do not shut off the second switch 7 even after a predetermined time during operation. It is necessary to provide a safety stop device 19 that shuts off the second switch 7 after confirming that the object is in a safe state even when the engine is shut off. The safety stop device 19 will be described in detail in the section explaining claim 2 and will be described later in an embodiment of a passenger car.

Next, intrusion prevention means of the antitheft device of the present invention will be described with reference to FIGS.

There is a possibility that a thief who has stolen an object that is equipped with an anti-theft device and cannot be used will enter the anti-theft device in order to be able to use the object. The higher the use value of the object, the higher the possibility of intrusion, and there is a case where the object is invaded by a systematic and advanced technique.

FIG. 43 is a diagram showing a range in which intrusion prevention means is applied to the electronic circuit 2D of the antitheft device of the present invention within a bold dotted frame. The antitheft device of the present invention does not lose its effectiveness unless it enters the range of the thick dotted line.
FIG. 44 shows that the generated identification signal 15B and connection signal 18B are in the intrusion target range 9.

FIG. 45 is an anticipation of intrusion with respect to the antitheft device of the present invention. After the penetration to the central part of the electronic circuit body, the second switch 7D can be mechanically connected or bypassed, and the second switch 7D with a false identification signal or a false connection signal. An electrical intrusion that connects the two is considered first. It is also possible to enter the memory of the identification device. Furthermore, there are a wide variety of intrusion means such as a timepiece mechanism also becoming an intrusion place, such as stealing when in a usable state and intruding into a timing device to extend a predetermined time.

However, there is a high possibility that a thief invading with the above-described advanced intrusion technology is a specialized and organized thief group. The prey targeted by such a thief group tends to be limited to expensive objects such as expensive vehicles and IC cards. The reason is that the thief group does not do the inefficient act of stealing cheap things with advanced technology and effort. Therefore, if it can withstand the intrusion of the thief group as described above, it can withstand all intrusions.

The antitheft device of the present invention is an antitheft device that can be provided with intrusion prevention means that is extremely difficult to break. An intrusion prevention means that provides a sufficient anti-intrusion effect even for the above high intrusion technology will be described below.
The conclusion of intrusion prevention means is IC. The main component of the antitheft device of the present invention is an electronic circuit. Therefore, the main components in the intrusion prevention range 9 within the thick dotted line frame in FIG. 43 can be integrated. Therefore, intrusion can be prevented by protecting the IC with the IC package structure. In general, since an IC package has a robust structure, it is difficult to break the IC package without damaging the IC body. Even if the IC main body is penetrated and reached, it is impossible to enter the fine structure of the IC main body at a general technical level. Therefore, it is possible to have a strict and advanced intrusion prevention function that prevents third parties from entering. Therefore, a theft countermeasure device that cannot be intruded can be made.

The intrusion prevention range 9 shown by the broken lines in FIGS. 43 and 44 is a range in which the basic function itself of the anti-theft device of the present invention may be violated in the event of an intrusion. Strictness depends on the design because there is no need to make public. Therefore, in the case of carrying out with individual objects, the intrusion prevention target range is not defined in the range of the broken line in the figure.

Even if all of the electronic components within the intrusion prevention range shown in FIGS. 43 to 45 cannot be integrated into an IC, there are many means for preventing them from entering the electronic circuit. Even if a high-severity intrusion prevention unit is not provided like an expensive vehicle or an IC card, a thief can be prevented from entering or the intrusion can be given up with a low-severity intrusion prevention unit.

In the case of an inexpensive object, the enclosure of the object cannot be opened with a + or minus driver, or the electronic circuit of the anti-theft device cannot be reached simply by opening the enclosure. The intrusion prevention means by is first effective. Next, intrusion prevention means on the electronic board is effective, such as making it difficult to understand where the electronic circuit of the anti-theft device is located on the electronic board, for example, if the electronic board is multi-layered.

In theft of inexpensive objects, the thief is likely to give up further intrusion at this point, so these means can be called effective intrusion prevention means. The reason is that a thief who steals an inexpensive object does not have the advanced and systematic electrical knowledge, electrical technology and equipment necessary for intrusion, and even if he has it, it takes time and effort to make it cheap. I wo n’t pay as a thief.

As another intrusion prevention means, there is an example in which a plurality of blocking portions 5 of the central portion 4 are provided. In order to keep the electronic circuit from moving normally, it is sufficient to block one central part, but as a means to make invasion prevention more severe, a method of providing a plurality of blocking parts in the central part There is. It is effective as a means to counter thieves with organized invasion techniques that steal expensive vehicles.

Moreover, the effect according to intrusion prevention can be obtained by shortening the setting of the predetermined time.

It is also necessary to consider intrusions from timed devices. There are intrusions such as being stolen when it is usable and changing the setting of the clock, extending the usable time by changing the setting of the predetermined time, and being stolen within the predetermined time It is also conceivable that the predetermined time does not elapse when the time is stopped. This is an intrusion derived from the fact that the antitheft device of the present invention can share the clock mechanism, power supply device, and the like originally possessed by the object.

Intrusion prevention measures Therefore, intrusion such as not entering the clock function unless a predetermined signal is input, shutting off the second switch when the clock function stops, or receiving only the clock signal and timing in the anti-theft device It is necessary to protect with a prevention mechanism. There is also a method in which a dedicated clock function or timer function is built in the connection duration indicating device with a time limit.

Of course, if a given signal itself is deprived, it will naturally be invaded, but the type of a given signal such as a given signal that will not be taken away such as a blood vessel image or iris image of the hand Since there are various management methods, the intrusion is described based on the absolute condition that the predetermined signal is managed by the administrator.

FIG. 46 is a list of objects to be symmetric in claim 4, and the following are the main objects. Of the vehicles referred to in the Road Traffic Law, all vehicles that are driven by electronically controlled driving devices include snowmobiles. An aircraft that operates with electronically controlled drives. Includes a water bike on a ship that is powered by a drive under electronic control. Civil engineering machinery that is driven by electronically controlled drives, including outdoor generators. Portable information terminals such as notebook computers and electronic notebooks. Mobile phone. Portable electronic devices such as headphone stereos, portable game consoles and portable TVs. Home appliances such as TVs, video recording / playback devices, game machines, refrigerators, washing machines, and microwave ovens. Film cameras that operate under the control of digital cameras, video cameras, and electronic circuits. IC card. Composite products with IC cards such as mobile phones, information terminals, portable electronic devices, wallets and pendants. In addition, all objects that require electronic circuits to operate and can be stolen because they are movable are targeted.

Here, the operational aspect of the predetermined time will be described. The predetermined time is a time during which the object incorporating the antitheft device of the present invention is kept in a normally moving state.

Setting a short time such as 30 seconds or 3 minutes is used for IC card settlement. In the case of an IC card, it is sufficient that the card moves normally only when it is settled, and it is illegally used to keep the normally moving state longer than necessary.

Also, setting a short time such as 30 seconds or 3 minutes may be used for starting a vehicle or the like. The normal movement state is set only when the engine is started, and the end of the normal movement state is set by the time when the engine is stopped by the engine key, and is stopped by the safety stop device. An advantage of this is that it can be made not to work properly from the moment the engine is turned off.

Examples such as 3 hours or 8 hours are convenient time settings for many objects. The special feature of the anti-theft device of the present invention is that it can be used normally without worrying about the anti-theft device once it is in a normal operating state, such as a mobile phone, video camera or digital camera. It is a feature to do.

An example of setting for a long time will be described. There is a method of making a long time such as one month, three months, or 180 days by inputting a predetermined signal once. It is troublesome to input a predetermined signal every time it is used or every few days in the case of home appliances or office equipment. The risk of being stolen is extremely small compared to portable items that are taken outdoors. However, it is convenient to set a predetermined time for a target that provides a sense of security when equipped with an anti-theft device. There are cases. For home appliances, office equipment, desktop computers, etc., a long period of time is a countermeasure against theft. There is also an input method in which a predetermined signal input date is determined once a month. In addition, even if it is stolen, the thief does not know when the end of the predetermined time is, so it is anxious about when it can not be used, and it displays a high anti-theft effect by displaying that the anti-theft device is installed be able to.

In addition, as an application of a predetermined time, a method of moving both connection and disconnection for a normal operation state by a reserved time can be adopted. The reservation function works automatically and can be used repeatedly for one hour in the morning reservation and one hour in the night reservation for objects that have been used for commuting vehicles and IC card function commuter pass functions. And so on. As a result, only in the case of regular use, the target time zone can be automatically used without any action.

The input device separated in claim 3 or the object on which the separated input device is mounted will be described below.

The separated input device is a device for inputting a predetermined signal from the outside as an external input device 20 into an IC card incorporating the anti-theft device without the predetermined signal input device of claim 5. Anti-theft devices that do not have an input device are used for objects that are difficult to secure the installation location of the input device, such as IC cards, as well as vehicles and ships that tend to be separated from the electronic circuit of the anti-theft device. The

Since the operation of the circuit of the separated input device 20 is described in the section of claim 3, redundant description is avoided.

47 to 50 are diagrams illustrating the external input device.

FIG. 47 shows an example of an external input device 20A in the form of an input plate 27. The external input device 20A has an input device switch 11D, and a predetermined signal 13C has a predetermined signal input button 41 and an input confirmation display device 40 because it is an example of using a password or a password for the predetermined signal 13C. In the case of a multi-function type IC card, a function selection button 44 and an execution button 42 are provided. In the case of passenger cars, motorcycles, etc., if there is a lock button 43, it is convenient because the remaining predetermined time can be canceled and the second switch can be shut off to immediately make it not function properly. .

The operation of the external input device 20 is activated by a switch 11D of the input device, inputs a predetermined signal 13, and pushes an execution button as it approaches or overlaps a receiving unit of an object such as an IC card or a vehicle. Thus, a predetermined signal is transmitted. In the case of other than the IC card, the basic operation to be transmitted to the receiving unit is the same.

FIG. 48 shows a case where a fingerprint image is used for a predetermined signal. The shape is an example of an external input device 20B in the shape of an input board 27A, which is an example having a fingerprint sensor 117, an input device switch 11E that also functions as a transmission button, and an operation confirmation lamp 118. The operation is started by the switch 11E of the input device, the fingerprint is read by the fingerprint sensor 117, and the switch 11E of the input device is pushed by approaching or overlapping the receiving unit of an object such as an IC card or a vehicle.

FIG. 49 is a schematic diagram of an electronic circuit of the external input device 20. The input unit 30, the transmission unit 22 of the communication means 21, and the power supply device 28 are main components. The communication means 21 is an example using electromagnetic waves and has a transmission antenna 23. The communication means 21 includes a bidirectional case.

The communication means 21 of the external input device 20 has an antenna in the case of radio waves, a light emitting portion and a light receiving portion in the case of light, and a connection terminal in the case of a contact type, depending on the communication method.

FIG. 50 shows a mobile phone 89 equipped with an external input device. The function of the electronic circuit of FIG. 49 is mounted in the cellular phone.

Since the portable telephone is highly portable, it is convenient as an object on which the external input device of the antitheft device of the present invention is mounted. Further, the advantage of mounting the external input device on the mobile phone is that the mobile phone can share most of the external input device other than the transmitting / receiving antenna.

Therefore, when the antitheft device of the present invention becomes widespread in the future, in order to cope with an object for inputting a predetermined signal by the external input device, a mobile phone 89 as shown in FIG. Is required.

A cellular phone device 89 as shown in FIG. 50 is easy to use both as an external input device for motorcycles and vehicles and as an external input device for IC cards. If an external input device is included in the function selection section of the mobile phone for input operation, there is no need to provide a dedicated switch on the mobile phone, but in FIG. 50, the input device switch 11F is added. Thus, a predetermined signal can be directly input.

In the case where the external input device 20 takes the form of an input board as described above, and when the function of the external input device is mounted on a mobile phone or the like, the external input device 20 is mounted on a read / write device for settlement, If a dedicated machine for an external input device installed near the reading / writing device of a financial institution is effective in preventing unauthorized use and measures against theft.

An IC card for inputting a predetermined signal by an external input device will be described in detail in the section of the embodiment.

The anti-theft device of the present invention is a device that prevents a thief from stealing, that is, a device that cannot be stolen by making it appear that it is useless. A method and means for actually preventing theft with the antitheft device of the present invention will be described.

First, referring to FIG. 51, a mechanism for preventing the theft by notifying that an anti-theft device is incorporated in an object incorporating the anti-theft device of the present invention, and a theft different from the conventional method. The countermeasure means will be described.

FIG. 51 is a diagram illustrating the psychology and behavior of the thief, assuming the psychology of the thief, under two conditions when the thief steals an object.

Focusing on the conditions under which an object is stolen, it can be seen that an object steals when it has the following two conditions. The first condition is that the object has the value that you want to get even after it is stolen. The second condition is being in a stealing environment. The environment that can be stolen includes no lock, no anti-theft device, no watch.

The object A in the table indicates that there are two conditions: the value that the first condition is desired to be obtained even after the first condition is stolen, and the environment in which the second condition can be stolen. At this time, the thief steals and steals.

Of the objects B and C that do not have one of the conditions in the table, the object B has the first condition and does not have the second condition. In other words, even if it is stolen, it has the value that you want to get, but it is not in an environment that can be stolen, that is, it is locked or watched. Therefore, the thief wants to steal the object B but cannot steal it.

The antitheft method conventionally used is method B. However, this method has many gaps and may be stolen. In other words, if you want to steal, but you can't steal it, you can interpret it as if you have a feeling of stealing but there is no way of stealing, that is, no technology. Therefore, 1. You can steal if you have a technique to break a key or watch. 2. Can steal when unlocked or when no one is watching, that is, when there is a chance. 3. Robbing. You can steal if you use a trick like this.

Object C is in the second condition but does not have the first condition, that is, it is in a stealing environment, but is not worth it even if it is stolen. If it has no value, it will not be the target of stealing. If you know that it is worthless to steal, you will lose your feelings of stealing. Therefore, the thief does not steal the object C.

Object D that does not have two conditions is never stolen.

Focusing on the anti-theft device and anti-theft method of the present invention, what is implemented is an object under the condition of the object C, and an object having no value is not stolen. This is the basis of the antitheft means of the present invention.

There has never been a way for the owner to remove the value from the object while keeping the value of the object. If you give an approximate method, you can write a large name so that it cannot be erased. The reason why the name is written is difficult to be stolen because it is very difficult for the thief to use, that is, the value of use is impaired. In this way, if the value is greatly impaired or lost, the object will not be stolen.

Use value is lost. In other words, if the stolen object cannot be moved anyway, the use value is lost. If there is no use value, the purpose of stealing will be lost. Theft that prevents the thief from telling the thief in advance that it can not be used by telling the thief in advance that the object is in a state that does not move normally and has lost its value of use Measures can be taken.

As described above, the anti-theft device of the present invention is a device that is not used when it is stolen, but the intended original effect is an effect of scraping the thief's willingness to steal before it is stolen, This prevents theft.

Since this anti-theft method is unfamiliar, it is naturally not recognized by the general public, especially by thieves. There is a drawback that the fact of the effect is difficult to convey unless the thief experiences that it cannot be used even if it is stolen. Therefore, until the recognition, the anti-theft effect of the anti-theft device may be small, and this is unavoidable.

If the anti-theft device of the present invention is installed, the more theft information is recognized by the thieves, the less theft will be. This effect is particularly effective for organized thieves. After the anti-theft method of the present invention has been widely recognized, it is only necessary to announce that the anti-theft device of the present invention is installed, so that the intended effect of the anti-theft device and anti-theft method of the present invention is achieved. I can give you.

Therefore, in order to prevent theft by the antitheft method according to the present invention, it is possible to notify the thief by a notification means such as a mark, a picture, a character, a sound, a video, etc. that the object is equipped with the antitheft device of the present invention. It becomes a necessary condition.

An example of notification will be described with reference to FIGS. In any case, print media, video, audio, and other notification media can be used, such as engraving on the object, printing, sticking with a sticker, projecting on the display screen, marking on the packaging of the object, or marking in a notification advertisement or catalog. Use and announce.

FIG. 52 shows an example of a notification mark that is an image of a lock.

FIG. 53 shows an example of a notification mark that is an image of a key.

FIG. 54 shows an example of a warning seal tone notification mark. It can be displayed on a computer screen with a built-in anti-theft device and used for a warning text with a built-in anti-theft device of the present invention.

FIG. 56 shows an embodiment in which a notice mark reflecting the key of FIG. 45 is attached to an IC card equipped with the antitheft device of the present invention.

FIG. 57 shows an embodiment in which a notice mark reflecting the key of FIG. 45 is attached to a digital camera equipped with the antitheft device of the present invention.

FIG. 58 shows an embodiment in which a notice mark reflecting the image of the lock of FIG. 44 is attached to a product packaging box equipped with the antitheft device of the present invention.

FIG. 59 shows an embodiment in which a warning seal-like notice mark shown in FIG. 46 is attached to a product packaging box equipped with the antitheft device of the present invention.

FIG. 60 is an example described in a notice advertisement, catalog, in-store broadcasting, and the like.

As described above, the antitheft device of the present invention is not intended to counter the thief who is trying to steal with a key or an alarm device, but is a antitheft device that specifically implements the antitheft method that eliminates the thief's willingness to steal. It is. Therefore, the notification means for notifying the thief that the anti-theft device of the present invention is incorporated has an important role.

So far, the function and principle of the electronic circuit of the present invention as a theft countermeasure device have been described. From here, the Example which incorporated the electronic circuit of this invention in the target object as an electronic circuit with an antitheft device is described. In the description of the embodiments for carrying out the present invention, the same components as described in the above principle are denoted by the same reference numerals, and redundant description is omitted.

It is the Example which incorporated the electronic circuit which controls a 2nd switch with a means as an antitheft device of a passenger car.

Of the antitheft device of the present invention, the input device 12C for a predetermined signal is attached to the position of the circle A on the dashboard.

62 is an enlarged view around the dashboard 52 to which the input device 12C of FIG. 61 is attached. The input device 12C is installed near the engine start switch 51 as a place that is easy to see when inputting a predetermined signal and does not interfere with the instrument panel 53 or driving. Near the engine start switch 51, a notification mark lock 65 equipped with an anti-theft device is attached to notify that the anti-theft device is installed.

63 is an enlarged view of the input device 12C of FIG. A predetermined signal 13 consisting of a code number or code is displayed on the display device 40. An example of an input method is to simply press the switch 11G of the input device, input the predetermined signal 13 with the predetermined signal input button 41B, and press the execution button 42. When the input device is always on standby, there are various input devices and input methods, such as that the input device switch 11G is not necessary or the execution button 42 is not pressed, and the figure is not limited.

The function selection button 44A is used for registration / change of a predetermined signal, setting change of a predetermined time, and the like.

Regardless of the rest of the predetermined time, the lock button 43A can immediately turn off the second switch to make the passenger car 50 unusable when pressed. However, it is necessary to provide a safety stop device that does not function during operation or that does not stop until the engine start switch 51 is turned off even if it is pressed.

63, the display device 40 and the execution button 42 that can confirm that the predetermined signal 13 is correctly input are provided, but the display device 40 and the execution button 42 are not necessarily required.

Problems with the placement of the input device occur with large objects such as the passenger car 50. In the case of a large object, there will be a distance between the input device and the electronic circuit body. There is a possibility of eavesdropping on a predetermined signal. Therefore, it is preferable to use an optical fiber during this time, make a secret communication, or use an electromagnetic remote control with a short reach. The input device in this case includes a direct input directly connected to the identification device 14 and a method of making the input device 12 a remote control type.

In addition, when the passenger car 50 is standardly equipped with car audio and car navigation, the input device 12 can also be used as an input device of the antitheft device of the present invention using input means such as those input buttons and remote control. is there.

There is also a method in which the passenger car 50 already has a digital display device such as a speed, a travel distance, and an air temperature, a display switching button, and the like, and an input device of the identification mechanism of the antitheft device of the present invention.

Referring back to FIG. 61, the electronic circuit portion of the antitheft device according to the present invention is mounted on the circle B in the corner of the IC chip 39 in the IC package 38 in the circuit board 37 of the electronic circuit of the engine control device 55. Has been inserted. The figure is an image.

In this case, the structure for preventing intrusion into the IC chip 39 is first protected by the robust IC package 38. The IC package 38 is mounted on an electronic circuit board 37, and the electronic circuit board 37 is a part of the engine control device 55. The engine control device 55 is protected by an engine control device storage box 54 and is provided at a predetermined place of the passenger car 50. It is fixed to.

In the case of a passenger car, such an arrangement itself becomes an intrusion prevention means. If the engine control device storage box 54 is sealed to form a black box, it becomes a more severe intrusion prevention means. Even if an intruder reaches the IC package 38, it is difficult to break the IC package 38 without damaging the main body of the IC chip 39. Even if the intruder reaches the IC chip 38, there is no advanced technology due to the fineness of the IC structure. Cannot enter the circuit. In other words, the antitheft device of the present invention can be made so that no intrusion can be achieved no matter what the thief does.
Intrusion prevention means. The anti-theft device of the present invention is characterized by notifying an intrusion, but giving up intrusion, that is, giving up stealing, by notifying that the intrusion is useless. For this reason, it is important to provide support for intrusion prevention means that cannot enter.

FIG. 64 is a schematic diagram of an electronic circuit in circle B of FIG. 2 is a schematic diagram of an electronic circuit 2 of the antitheft device of the present invention built in an engine control device 55 of a passenger car 50. FIG. Although the highly complicated electronic circuit of the passenger car 50 is expressed in a very simplified manner, the purpose and effect of providing the second switch in the central portion are the same as those described above.

FIG. 64 shows the control device 10E having the input device 12C, the identification device 14D, the time limit device 16D, the connection instruction device 17D, and the safety stop device 19C as main components, and the second switch 7E under the control of the control device. The electronic circuit 2E of the passenger car 50 which consists of the electronic circuit main body 4E is represented.

FIG. 64 shows a state where the object is at rest, that is, a state where the passenger car does not move normally. Unless the predetermined signal 13 is input to the input device 12C, the time-limited connection instruction device 16D does not place the second switch 7E in the connected state, so that the passenger car 50 does not move normally even if the engine start switch 51 is turned on.

Even when mounted on the passenger car 50, the method of using the antitheft device is simple. First, when the input device 12C is activated with the switch 11G of the input device and then a predetermined signal 13 is input, the passenger car is in a state of moving normally. If the input device 12C is always in a standby state, the operation of turning on the switch 11G of the input device is not necessary, and only the predetermined signal 13 is input.

If the predetermined signal 13 is correct, the engine control device 55 of the passenger car 50 immediately enters a normal state, and the normal state continues for a predetermined time. Therefore, if it is within a predetermined time, the passenger car can be used freely by normally starting the engine with the key without being involved in the anti-theft device. A similar method can be used for a keyless system. For example, if a predetermined signal is input in the morning with a predetermined time of 12 hours, anyone in the family can use it normally by the conventional method during the day. If the last user leaves it alone, the car will automatically return to an unusable state after 12 hours. The ability to use in this way is a major feature of the antitheft device of the present invention. Even within a predetermined time, the lock button 18 can immediately disable the operation. In addition, since it is dangerous to stop suddenly after a predetermined time while traveling, in this case, the above-described safety stop device is operated.

When a signal that is not a predetermined signal is input to the input device 12, there is a method of not performing anything, such as rejecting the input for a certain period of time after being input a predetermined number of times or issuing an alarm signal to a separate alarm device Functions can also be attached.

When changing a predetermined signal or setting for a predetermined time, it is common to use a method of calling a setting change function with a predetermined signal.

Measures to be taken when the administrator forgets a predetermined signal or when the maintenance department for regular maintenance inspections operates normally, for example, the seller manages a predetermined signal for the seller. Measures such as sharing a predetermined signal of a passenger are particularly necessary in the case of a passenger car.

As long as the antitheft device of the present invention uses an electronic circuit for engine control, a method according to this embodiment can be used for snowmobiles, water bikes, ships, airplanes, outdoor generators, and the like.

FIG. 65 is a schematic diagram when the input device 12 is an external input device 20. This method, in which FIG. 63 may be used as the input board type external input device 20, has the advantage that the installation location of the input device is not required on the dashboard, but there is a problem that the passenger car will not move if the input device is lost. There is also a method of mounting the external input device 20 on a mobile phone.

66 to 68 show an embodiment in which the antitheft device of the present invention is mounted on a motorcycle 57. FIG. There has been no effective anti-theft device using an electrical method so far, so this is an example that demonstrates high effectiveness as an anti-theft device mounted on a motorcycle. In addition, this Example is applied also to the object which uses the electric motor controlled by an electronic circuit, such as an electric motorcycle, an electric bicycle, and an electric wheelchair, for motive power.
FIG. 66 is a diagram of the windshield 58 and the rearview mirror arm 59 in front of the instrument panel 53 and viewing the instrument panel from the driver's line of sight. The method of mounting the electronic circuit portion of the antitheft device of the present invention in the engine control device is the same as that of the passenger car 60 shown in FIG. FIG. 10 is a view of the input device 12B mounted near the instrument panel 53A of the motorcycle 57.

In the case of a motorcycle that is exposed to the outdoors for a long time, there is a method in which a predetermined signal is input by an external input device. In this case, the external input device 20 has a combination of making the input device 12 a remote control type or a mobile phone equipped with the external input device.

FIG. 67 is an enlarged view of the instrument panel 53A of FIG. The display device 40A of the input device 12B also serves as the display device of the instrument panel 53A.

A notification mark key 66 is inserted near the engine start switch 51A to notify that the antitheft device is installed.

FIG. 68 is an enlarged view of the input device 12 of FIG. In the embodiment, a numeric keypad type is used for the input device 12B. However, since the place is small in the case of a motorcycle, a method of reducing the number of input keys by combining a feed key, a return key, and an execution key may be used.

The normal usage method of the input device 12B is to press the switch 11 of the input device, input a predetermined signal with the predetermined signal input button 41, and press the execute button 42. This operation puts the motorcycle into normal motion.

The lock button 43 can be disabled immediately even within a predetermined time. It should be noted that a safety stop device that does not stop during traveling or when the engine is running is indispensable so that a predetermined time may not pass during traveling. The operation of the safety stop device is the same as that of the passenger car shown in FIG.

The schematic diagram of the electronic circuit of the antitheft device of the present invention on the motorcycle side is basically the same as that of a passenger car.

Note that a safety stop device is indispensable for passenger cars because of the feature of the anti-theft device of the present invention that the object is not moved. In addition to the vehicle, it is better to include a device according to the safety stop device when the anti-theft device of the present invention is incorporated in a computer that causes inconvenience if it stops suddenly.

Here, an example of the operation of the vehicle safety stop device will be described using the flowchart of FIG. 69 and the time charts of FIGS. 70 and 71.

FIG. 69 is a flowchart of the antitheft device with a safety stop device for a vehicle. After a predetermined time has passed, the vehicle that has been in a state of moving normally by checking a predetermined signal will confirm that the safety stop device is not in an operating state such as the engine is stopped or the engine key is turned off. The connection signal is stopped, and sudden stop is prevented when a predetermined time has passed during operation.

FIG. 70 is a time chart of the anti-theft device with a safety stop device. The line A in the figure is the line where the predetermined time has ended. The safety stop device issues an instruction to continue the transmission of the connection signal up to the line C for confirming that the engine is stopped or stopped at B, thereby preventing the stop during operation.

71 is an example in which the engine stop confirmation method of the safety stop device is different from that in FIG. The safety stop device has received engine operation information and is operating in a manner that stops the connection signal only when the engine is not running after the point A when the predetermined time has elapsed or when the engine stops at the point B Preventing the stoppage.

In either case, if the vehicle is not in operation at the time point A, the connection signal is stopped and the vehicle is not moved normally.

The engine stop confirmation method described with reference to FIGS. 69 to 71 is an example. It is a safety stop device that does not stop suddenly during operation, and there are various methods for detecting that it is in operation, such as obtaining from the state of the engine key or from the signal of the engine control device. It is not specified.

72 to 75 show an embodiment in which the antitheft device of the present invention is mounted on a digital camera. The second switch is a control means mainly composed of an input device, an identification device, a connection instruction device, and a time-limit device. It is the Example using the electronic circuit which controls this.

FIG. 72 is an explanatory diagram when the operation buttons and the display device already provided in the digital camera 60A are also used as the input device of the antitheft device of the present invention. The switch 11 of the input device also serves as the power switch 3 of the digital camera. The predetermined signal input button 41 uses an operation button of the digital camera 60A. A monitor screen of a digital camera is used as the display device 40 for confirming the input of a predetermined signal. Electronic devices that already have operation buttons and display devices that can be used in combination as described above can be used for the present invention without adding new parts without impairing the original appearance of the electronic device. An anti-theft device can be installed.

FIG. 73 shows an embodiment in which the antitheft device of the present invention is integrated with the electronic circuit of the digital camera 60A. The electronic circuit of the antitheft device is integrated in a circle C of a corner of the IC chip 39 protected by the IC package 38 of the substrate 37 of the electronic circuit of the digital camera 60A.

FIG. 74 is a schematic diagram of the electronic circuit of circle C in FIG. It is a schematic diagram of the electronic circuit of the antitheft device of the present invention built in the electronic circuit 2 of the digital camera 60A, and represents a state where the electronic circuit is at rest, that is, it does not function normally. Since the second switch 7 is not connected unless a predetermined signal is input to the input device 12, the digital camera does not function normally. Moreover, a mechanism is described in which an electronic circuit is in an IC and cannot be easily penetrated.

In FIG. 74, the power switch 3 for the object and the switch 11 for the input device are combined. This has the advantage that it is not necessary to provide a new input device switch on the object, but it is confusing for the administrator, so it is necessary to automatically switch between the two switch functions.

FIG. 75 is a flowchart showing an example of function switching when the power switch 3 is also used as the switch 11 of the input device. From the start. The power switch was pressed. Check the status of the second switch. Is it connected? . If yes. Functions as a power switch. Turn on the power. It is the end. In the case of No. Functions as an input device switch. The operation button and display device of the object are switched to the function of the input device. Start the input device. It is the end. Therefore, it is preferable to provide such a switching device 47 that functions as a switch of the input device when pressed when not functioning normally and functions as the power switch 4 when functioning normally.

The usage of the anti-theft device for digital cameras is simple. First, the input device switch 11 is turned on. Next, a predetermined signal may be input with the input button 41 of the predetermined signal and the display device 40. The switch 11 of the input device returns to the original function of the power switch of the digital camera when the digital camera is in a normal functioning state.

If the predetermined signal is correct, the digital camera immediately enters a normal functioning state, and the normal functioning state lasts for a predetermined time. Therefore, the digital camera can be freely used within a predetermined time regardless of the antitheft device. For example, if the predetermined time is set to one hour, it can be kept in a state where it can be used normally by the conventional usage method for one hour after the input of the predetermined signal. If you leave it in use, it will automatically return to an unusable state after one hour. There is also a method of providing a lock function for the case where it is desired to keep the movement even within a predetermined time. The lock function is the same as the function described in the vehicle input device.

It should be noted that the electronic circuit of the antitheft device of the digital camera is integrated into an IC in order to reduce the mass production effect and the installation cost in addition to the effect of making the intrusion prevention mechanism strict.

However, in the case of low-priced objects such as digital cameras and headphone stereos, it is unlikely that a thief who has stolen will systematically infiltrate the electronic circuit of the anti-theft device with effort and expense. It is not always necessary to increase the severity of Even if the antitheft device is not hidden in the IC chip, it is hidden in the inner layer of the electronic board, it is difficult to reach the electronic board, or the set screw of the housing cannot be turned with a normal tool. It can be a sufficient intrusion prevention mechanism.

76 and 77 show an embodiment in which the antitheft device of the present invention is mounted on a headphone stereo.

FIG. 76 shows an example of a headphone stereo using a music medium such as a semiconductor memory, a hard disk, an MD, a CD, or a cassette tape. The IC chip 39 in the IC package 38 of the electronic circuit board 37 inside the headphone stereo main body 62 is shown. This is an example in which the electronic circuit of the antitheft device of the present invention is mounted on a single circle D.

For the operation of the anti-theft device, the switch 11 of the input device is turned on, and a predetermined signal is input with a predetermined signal input button also serving as an operation button of the headphone stereo main body. Confirmation of the input status of a predetermined signal is performed by a display device. This operation is basically the same for the above-described vehicle and digital camera.

FIG. 77 is a diagram of the electronic circuit of the antitheft device for the circle D in FIG. 76 and the electronic circuit of the headphone stereo. In the embodiment, the power switch 4 of the headphone stereo and the switch 11 of the input device are provided separately, but a switching device may be provided in one switch as described in the previous digital camera. Note that the input device may be mounted on the remote control side, and there is an object for operating the headphone stereo main body only on the remote control side. In that case, it is preferable to provide an input device for a predetermined signal on the remote control side.

The antitheft device of the present invention

78 and 79 show an embodiment in which the antitheft device of the present invention is mounted on a mobile phone. In the future, mobile phones will be equipped with high-performance camera functions, etc., and will become more and more valuable, so anti-theft devices will be useful.

FIG. 78 illustrates that the operation button and the display device originally possessed by the mobile phone are also used as a predetermined signal input device of the antitheft device. Among the input devices 12, the input device switch 11 is added on the operation surface, but the input button 41 for a predetermined signal and the display device 40 are used by switching what the mobile phone originally has. The switch of the input device can also be used as a power switch of the mobile phone or other operation buttons. As described above, since the mobile phone has a display device and many operation buttons, it is very convenient to use it as an input device for a predetermined signal.

FIG. 79 is a schematic diagram of an electronic circuit when the antitheft device of the present invention is mounted on the electronic circuit of a mobile phone.

FIG. 79 shows a state where the second switch is in a cut-off state and the mobile phone does not function normally. However, in the case of a mobile phone, it is safe to make all the functions not functioning properly, so the parts effective for anti-theft measures, such as the calling function or the display device, are not functioning properly. Therefore, it is necessary to install a second switch at a predetermined location such as a state where the reception function is functioning normally.

FIG. 80 shows that the anti-theft device of the present invention has a particularly high effect on an object in a use form such as a digital camera, a headphone stereo, a mobile phone, etc., that has a short use time and a high use number. Explains that The advantage of using the antitheft device of the present invention is that once a predetermined signal is input, it can be used any number of times for a predetermined time regardless of the antitheft device. In conventional antitheft methods, it is common to unlock before use and lock each time use is finished. An example of a cellular phone has a dial lock function, but the method of releasing the lock every time it is used is troublesome. As shown in the figure, in use 1 to use 3, there is a great problem in practicality because an unlocking action and a locking action are required each time it is used. That is, even if a conventional antitheft device is put into practical use, it becomes an unsuitable device for an object with a short use time and a large number of uses.

In that respect, the present invention can be freely used any number of times regardless of the operation of the anti-theft device after a single act of inputting a predetermined signal at the beginning of use for a predetermined time period. Mobile phones, digital cameras and video cameras can be used without worrying about anti-theft devices.

  Furthermore, it has the feature that even small objects can be mounted, and even inexpensive objects can be mounted.

This feature is also effective for motorcycles and passenger cars. If the predetermined time is set to 12 hours, when driving a day, if a predetermined signal is input at 8:00 am before departure, the engine is started for the day regardless of the anti-theft device. It can be used normally regardless of the anti-theft device, such as turning off the engine and starting it when resting. Even if it is stolen with the key attached at this time, the thief can no longer move after 8 pm.

Next, an IC card incorporating the antitheft device of the present invention will be described with reference to FIGS. The anti-theft device according to the present invention is all built in an IC card having a thickness of about 0.76 mm, which is the embodiment of claim 6.

The antitheft device of the present invention is mostly made of an electronic circuit, but only the input device of the control means is made of a switch, an input button, a sensor, or the like. Therefore, a technique for inexpensively mounting the input device on a thin structure such as an IC card is required.

FIG. 81 shows an IC card when the thin packaging technology has advanced and all the antitheft devices of the present invention can be mounted at a low price, that is, a price suitable for spreading, to a thickness of 0.76 mm. This is an example of the main body 100D. FIG. 5 is an image diagram in which a predetermined signal input device is provided on the surface of a thin card, and an administrator inputs the predetermined signal by hand. By inputting a predetermined signal, the IC card can be made to function normally for a predetermined time such as 3 minutes, 10 minutes, or 12 hours.

82 is an overall view of the IC card of FIG. 81 in which the input device 12 is provided on the IC card surface 101 of the IC card main body 100. FIG. In this example, the photovoltaic device 111 is provided in the power supply device for driving the control means in addition to the switch 11 of the input device, the predetermined signal input button 41, the card function selection button 109, and the display device 40.

83 is a cross-sectional view taken along the line 83-83 in FIG. If it is mounted on the IC card main body 100 having a thickness of about 0.76 mm with the current built-in technology, it becomes an expensive IC card, but in the near future, this embodiment can be realized as an inexpensive IC card.

FIG. 84 is a flowchart showing the basic operation of the IC card of FIG. 81 equipped with the antitheft device of the present invention. start. A predetermined signal is input to the input device. The identification device collates and identifies a predetermined signal. Only when the predetermined signal verification is Yes, the IC card is set in a state of functioning normally for a predetermined time. The IC card is kept in a normally functioning state for a predetermined time. When the predetermined time is over, the IC card is returned to the original non-functional state. End. It is.

FIG. 85 is a schematic diagram of the electronic circuit 2 of the IC card main body 100. The IC card antenna 113 and the IC card electronic circuit 112 are components of the IC card. The electronic circuit of the antitheft device of the present invention is built in as follows. A second switch 7E is provided in the blocking part 6 of the central part 5 of the electronic circuit body 4E in the electronic circuit 112 of the IC card, and the input device 12, the identification mechanism 14 and the time limit for controlling the second switch are provided. A control means 10 having the device 16 and the connection instruction device 17 as main components is provided. Furthermore, a power supply device 28 that the IC card originally does not have is also provided. The time limiter 16 has a clock signal or time signal transmission mechanism because the IC card body originally does not have a clock function. However, the predetermined time in the case of an IC card is not necessarily an accurate clock device because a short time such as 3 minutes or 10 minutes is recommended if it is used for settlement.

The state in FIG. 85 represents a state in which the IC card does not move normally before the start of the flowchart in FIG. In other words, it cannot be used even if it is stolen. Since the second switch is in the cut-off state, the electronic circuit body 3 is in a state where it does not move normally. The IC card does not have a power switch and the IC card antenna is activated by radio waves from the reading / writing device. Therefore, in this state, even if the IC card antenna 113 receives the reader / writer's radio wave, the electronic circuit body of the IC card does not function normally.

FIG. 86 illustrates the operation of the electronic circuit when an operation is performed to bring the IC card in the state shown in FIG. 85 into a normal functioning state. 84 represents the time until the IC card in the flowchart of FIG. 84 is in a normally functioning state. A predetermined signal 13 is input by an input device 12 provided on the IC card surface 101. Upon identification of the predetermined signal 13, the identification device 14 that has received the predetermined signal 13 from the input device 12 issues an identification signal 15 </ b> A toward the connection instruction device 17. Upon receiving the identification signal 15, the connection instructing device 17 issues a connection signal 18 for instructing the second switch 7 to connect to place the second switch 7 in the connected state. After the predetermined signal is identified and until this time, the timing device 16 starts measuring the predetermined time. In this state, the electronic circuit 112 of the IC card is in a state of functioning normally, and the antenna 113 of the IC card emits in response to the radio wave 114 of the IC card and can perform transmission / reception with the reading / writing device.

FIG. 87 illustrates a schematic diagram of an electronic circuit when the IC card continues to function normally. The timing device 16 is measuring a predetermined time. Since the connection instruction device 17 continues to transmit the connection signal 18, the second switch maintains the connection state. The power supply device 28 is operating, and the input device 12 and the timing device 14 are stopped. When the predetermined time has passed, the state automatically returns to the state shown in FIG.

FIG. 88 is a schematic diagram of an example of an electronic circuit of the antitheft device of the present invention corresponding to multi-functionalization. An example in which a second switch 7 is provided in the central part 121 of a dedicated circuit for a function to be designated from among multiple functions, and a function selection device 120 is provided that sends a connection signal only to the second switch of the electronic circuit of the function. It is.

It is preferable to set the predetermined time of the IC card as short as 3 minutes or 10 minutes in order to prevent theft. As a usage method, a method of inputting a predetermined signal immediately before settlement is safe. Therefore, as long as this is the case, the timing mechanism of the identification device may be a timer function capable of timing for about 10 minutes.

In addition, in the case of cash withdrawals and financial institution settlements, a function that prevents unauthorized reading and writing in the predetermined time remaining after settlement is added by adding a function that can not be used for the second time once the settlement act is made. The effect as a theft countermeasure device can be made more severe.

Furthermore, in the case of an IC card having a plurality of functions, for example, a predetermined time is used as a regular ticket for transportation in the morning and evening, but the card function of a financial institution is set to 5 minutes. It may be more convenient to provide a function selection device such as setting. In this case, a timepiece device needs a clock mechanism.
IC card side

Here, the function selection device will be described. The IC card is used as a cash settlement function and a financial institution card as well as a regular ticket for transportation, and there is a case where a single card corresponds to a plurality of financial institutions. In addition, the multi-functionality of IC cards, such as identification cards and key functions, will become increasingly widespread.

In addition to being stolen and used for non-contact type IC cards, information on non-contact type IC cards can be illegally read or written by a third party with a portable reading / writing device. The anti-theft device of the present invention that blocks the electronic circuit itself of the IC card as a means of dealing with such a crime using electromagnetic waves on a non-contact type IC card is Highly effective.

The items described above are not limited to the IC card of FIG. 81, but also apply to an IC card and an electronic device equipped with an IC card function.

FIGS. 89 to 93 show that the thickness of the card is increased from 0.76 mm by installing the anti-theft device according to the present invention assuming that the standard of the card thickness is 0.76 mm. It is an Example of an IC card with an antitheft device.

FIG. 89 shows an IC card on which all of the antitheft devices of the present invention including an input device are mounted. If restrictions on thinning are relaxed, existing thinning technologies such as card-type calculators and remote controls can be used as the technology for mounting anti-theft devices on IC cards. The card surface 101 of the IC card main body 100A has a switch 11 of the input device, a recessed portion 106 for preventing malfunction of the switch 11 of the input device, and a card function selection button 109 corresponding to the case where the multi-functionalization of the IC card function is advanced. A predetermined signal input button 41 and a display device 40 are provided. The switch 11 of the input device is provided with a malfunction prevention device. This is an example in which the top of the switch is provided at a recessed position in the recess to deal with a malfunction that is pushed in the card slot.

90 is a cross-sectional view taken along line 90-90 in FIG. The position of the switch for preventing malfunction is described. In order to prevent the switch from being turned on unintentionally by being pushed in the card case or in the wallet, a recessed portion 106 is provided and the switch is depressed in a position recessed from the position 104 on the IC card surface. An example in which the height is provided is shown. In order to prevent malfunction, it is possible to freely press a plurality of switches at the same time, press a predetermined number of times, or hide them on the side of the card.

FIG. 91 shows an example in which a fingerprint sensor 117 is provided in the input device of the identification mechanism. On the surface of the IC card, a fingerprint sensor 117, a fingerprint sensor activation switch, that is, an input device switch 11, and an operation check lamp 118 are provided. The switch part of the input device has a recess 106 to prevent malfunction.

It is also predicted that the predetermined signal will be a fingerprint, an iris image, or a blood vessel shape. If the sensor is put to practical use and downsized, it will be used in the anti-theft device of the present invention. The predetermined signals and input devices are diversified. The diversification of predetermined signals and input devices can be used not only as an anti-theft device for IC cards but also as an input device for predetermined signals for anti-theft devices for all objects.

When using a fingerprint or iris image for a given signal, it is necessary to register it in the memory of the identification mechanism at the initial setting stage of the administrator. become.

FIG. 92 shows an example in which the switch 11 of the input device is provided in a laterally-pressed manner in the recessed portion 119 on the side surface recessed from the card side surface position 105. Since the IC card is easily pushed in a card compartment or a wallet, the prevention of malfunction as described above is effective.

93 is a cross-sectional view taken along line 93-93 in FIG. The side push type switch portion for preventing malfunction is described.

94 to 97 illustrate an embodiment in which the antitheft device of the present invention is mounted on an IC card of a mobile phone equipped with an IC card function. Mobile phones equipped with IC card functions are expected to become increasingly popular in the future. It is necessary to provide an antitheft device at least in the IC card mechanism.

FIG. 94 is a diagram in which two radio waves, that is, the radio wave 114 of the IC card and the radio wave 96 of the mobile phone, are emitted from the mobile phone 90 with the IC card function. Even for objects with such different functions, the electronic circuit of the mobile phone essential for the normal functioning of the mobile phone and the IC card indispensable for the normal functioning of the IC card Since each of the electronic circuits 112 has an anti-theft device, each of the different functions can be provided. Further, an antitheft device can be provided only on the IC card side or only on the mobile phone side. Note that the electronic circuit 112 of the IC card and the antenna 113 of the IC card shown in FIG. 94 are not actually visible because they are in the case of the mobile phone. Since the anti-theft device for mobile phones has already been described in the embodiment of FIG. 78, this section will focus on the portion in which the anti-theft device of the present invention is built in an IC card mounted on a mobile phone.

FIG. 95 is a diagram in which the mobile phone 90 with an IC card function in FIG. 94 is opened for use. In this way, by mounting an IC card that originally has no power source, input device, and display device in the mobile phone 90, the power source, input device, and display device necessary for the anti-theft device for the IC card can be reduced. Since all things on the mobile phone side can be shared, the advantage of the combination is extremely large. There is also the advantage that the 0.76 millimeter thinness limit is eliminated.

FIG. 96 is an enlarged view of the operation portion of FIG. An input device switch 11 of an IC card antitheft device is added to the original operation portion of the cellular phone. When inputting a predetermined signal of the IC card, if the switch 11 of the input device is first pressed and the operation button of the mobile phone is dedicated to inputting the predetermined signal of the IC card, the input of the predetermined signal is not performed. Simple. Clear use of anti-theft devices for IC cards and mobile phones can be done without error. However, there is a method in which a predetermined signal can be input by selecting a function of the cellular phone without providing the switch 11 of the input device.

In FIG. 96, when the switch 11 of the input device is pressed, the input button of the mobile phone becomes the input button 91 of a predetermined signal of the antitheft device for the IC card. Since the operation buttons and display devices of mobile phones have abundant functions, they can sufficiently cope with the multi-functionality of IC cards. Therefore, it is convenient and efficient to mount the antitheft device of the present invention on a mobile phone having an IC card function.

FIG. 97 is a schematic diagram of an electronic circuit when an antitheft device is mounted on the electronic circuit 112 of the IC card of the mobile phone 90 with the IC card function described with reference to FIGS. 94 to 96. In the figure, an antitheft device is also mounted on the electronic circuit of the mobile phone, but since it has already been described with reference to FIG. Although not shown in the figure, the power source and the clock device are those of a mobile phone.

FIG. 97 shows a state in which the IC card is not functioning normally. The input device for the predetermined signal uses an input device for a cellular phone. When a predetermined signal is input from the input device, the second switch 7 of the electronic circuit 112 of the IC card is kept connected for a predetermined time.

Note that the operation of the antitheft device of the present invention with respect to the IC card is as described in FIG.

FIG. 97 is a schematic diagram of an electronic circuit of a product in which a mobile phone and an IC card are combined. Make sure that the mobile phone can be used 24 hours a day, and that the IC card payment function cannot be used, or if the IC card becomes multifunctional, the transportation ticket function works only in the morning and evening. In this way, it is possible to make a function that is not used normally not operate normally by setting up a multi-functional correspondence such as allowing payment for 5 minutes only for the payment function.

In FIG. 81 of the sixth embodiment, the IC card equipped with a theft countermeasure device having a thickness of 0.76 mm has been described. However, in order to produce an IC card at a popular price, it is necessary to put into practical use a thinning technique for mounting the IC card at a thickness of 0.76 mm at a low price, and it takes time to put it into practical use. Therefore, the anti-theft device of the present invention is a means of incorporating the anti-theft device of the present invention in a thin IC card of 0.76 mm by today's production technology by separating the input unit of the input device from the anti-theft device body. The input device separation type anti-theft device as the external input device 20 is used. By separating the input device 12, the anti-theft measures of the present invention can be applied not only to an IC card but also to a large object such as a passenger car, and to an object such as a motorcycle that is difficult to secure the installation location of the input device 12. It becomes possible to mount the device.

FIGS. 98 to 108 illustrate an embodiment in which the antitheft device of the present invention is mounted on a 0.76 mm thin IC card.

This embodiment is an external input type IC card body 70 in which an antitheft device excluding the input device 12 of the antitheft device of the present invention is mounted on an IC card having a thickness of only about 0.76 mm. By separating the input device 12 into the external input device 20, the function of the antitheft device of the present invention can be mounted while maintaining the original thinness of the IC card.

In order to mount all of the antitheft devices of the present invention on an IC card having a thickness of about 0.76 mm and to manufacture at a popular price, it is necessary to depend on future thinning technology. As already explained, only the input device 12 is bulky with the antitheft device of the present invention, and the electronic circuits after the identification mechanism other than the input device 12 can be integrated into an IC, and can be incorporated into an IC of an IC card. it can. Accordingly, it is possible and easy to mount control means other than the input device 12 on an IC card having a thickness of about 0.76 millimeters even with current production technology. As a result, an IC card having the basic functions of the antitheft device of the present invention can be produced and manufactured at a popular price.

On the other hand, the part of the input device 12 that is separated may constitute the external input device 20 alone as the input board 27 to be used by being overlapped with the IC card, or the function of the external input device 20 is mounted on the mobile phone. In the case of an IC card of a financial institution, if the external input device 20 is provided near the settlement place, that is, the reading / writing device, or if the reading / writing device is equipped with the external input device 20, the In addition, the IC card can be brought into a normal functioning state. In addition, the external input device 20 can cope with the multi-function IC card. This embodiment corresponds to a separate external input device according to claim 7 or an electronic device such as a mobile phone equipped with the external input device, a reading / writing device, and a calculator.

An example of the usage method is to input a predetermined signal of the antitheft device of the present invention to the external input device 20 and via the electromagnetic wave 26 of the communication means 21 between the external input device 20 and the external input IC card 70, The data is transmitted to the external input IC card 70, and the external input IC card 70 is put into a state of functioning normally for a predetermined time. The method of transmitting the predetermined signal 13 to the external input type IC card 70, that is, communication between the input device separated from the IC card is performed by contact using electromagnetic waves such as radio waves, electromagnetic induction or light, or by providing contacts. There are various methods. However, since it is necessary to prevent eavesdropping on transmission signals, when using electromagnetic waves, use weak electromagnetic waves that cannot be communicated without bringing the IC card and input device close to each other, or have a structure that does not leak outside. It is necessary to take measures to prevent leakage such as communication using light, transmission using a contact point, and encryption of a signal.

In addition, the IC card originally does not require its own power supply device and timing device. Therefore, in the case of mounting the antitheft device of the present invention, it is necessary to additionally mount a power supply device and a clock device or a timer device as in FIG. 81 of the sixth embodiment.

98 to 108 show an anti-theft device excluding the input device 12 in the IC card body to form an external input IC card 70, and the external input device 20 is formed in the form of an input board 27. FIG. The entire electronic circuit of the antitheft device of the present invention, excluding the input device 12 portion from the control means 10, is mounted on the IC card, and the input device 12 adheres to the original thinness of about 0.76 mm of the IC card. Is mounted on the input plate 27 which is the external input device 20 having a free thickness. The communication of the predetermined signal 13 is performed by putting the external input IC card 70 and the input plate 27 on top of each other or close to each other.

FIG. 98 shows an external input IC card 70 incorporating an electronic circuit obtained by removing the input device from the antitheft device of the present invention. The normal state is a state in which it does not move normally, so it will not be misused even if it is stolen. When used, a predetermined signal is transmitted by an external input device such as an input board or a mobile phone equipped with the external input device. The means for receiving the predetermined signal 13 from the external input device 20 is an example in the case of performing electromagnetic induction between the induction coil 71 of the external input type IC card provided separately from the IC card antenna and the induction coil of the input plate. .

In the figure, since the induction coil 71 is built-in, it cannot be actually seen, so it is represented by a dotted line indicating the position. If the positions of the mutual induction coils are arranged at the center, the front and back of the card and the direction may be used at the time of input operation. Advantages of using the induction coil are that if it is used closely, there is little leakage and countermeasures against eavesdropping can be taken, and the structure is simple, and power can be easily supplied from the input board to the external input IC card 70 side. On the IC card surface 72, a notification mark key 66 for notifying that the antitheft device is mounted is drawn.

FIG. 99 is a schematic diagram of an electronic circuit of the external input IC card 70 of FIG. This corresponds to an electronic circuit that separates the input device and receives a predetermined signal from the external input device. The antitheft device of the present invention is mounted on an IC card body in the form of an electronic circuit. It comprises a second switch 7 provided in the central part 5C of the electronic circuit body 4C and a control means 10 for controlling the second switch 7. The control means 10 comprises a connection instruction device 17, a time limit device 16, an identification device 14, The receiving unit 24 of the communication means 21 comprises. Furthermore, a power supply device 28 for control means is added. FIG. 99 shows the state of the electronic circuit in a state where the IC card does not function normally.

In the case of an IC card, it is only necessary to be in a state of functioning normally only during settlement or authentication, which is an extremely short time operation. Therefore, it is safer to set the predetermined time to a short time such as 3 minutes or 5 minutes including the time immediately before the settlement. Therefore, the timekeeping function of the timing device 16 does not necessarily require long-term accuracy. Therefore, the time limiter 16 may have a timer function instead of a clock function. However, the advantage of shortening the predetermined time is when the IC card is used for payment, and it is specified when using another function, for example, as a regular means of transportation or as an ID card. Since the time is 12 hours or 8 hours, a clock function is necessary for such applications.

The IC card does not have its own power supply because it receives power from the reading / writing device via the antenna each time. Therefore, a power source for driving the control means of the antitheft device is required. In the embodiment, the power source for driving the control means is an electromagnetic induction coil received from the external input device 20 to charge the secondary battery, or in addition to this, a primary battery with a long battery life such as a photovoltaic secondary battery or a sheet type is used. There are cases where it is used. These methods can be adequately handled by conventional techniques.

FIG. 100 illustrates an operation when the electronic circuit of FIG. 99 receives a predetermined signal from the input board 27 and enters a normal functioning state. An induction coil 71 of the external input IC card 70 receives a predetermined signal of an electromagnetic wave emitted from the induction coil of the input device, which will be described in detail later, and sends it to the identification device 14. When the identification device 14 identifies that the predetermined signal 13 is correct, it issues an identification signal 15 to the connection instruction device 17. Upon receiving the identification signal 15, the connection instruction device 17 issues a connection signal 18 to put the second switch 7 in the connected state. At this time, the timing device 16 starts measuring a predetermined time.

FIG. 101 shows the operation when the connection state after FIG. 100 is maintained. A state in which the connection instructing device 17 issues a connection signal to place the second switch in a connected state and the electronic circuit main body functions normally until the timing device 16 that is measuring the predetermined time ends measuring the predetermined time. To last. At this time, if radio waves come from the reading / writing device, the antenna 113 receives and transmits the radio wave 114 of the IC card and operates normally as an IC card.

FIG. 102 is a schematic diagram of an electronic circuit on the input plate 27 side, and represents main components as the external input device 20. This electronic circuit is paired with the electronic circuit of FIG. Therefore, there is an induction coil 81 of the input plate 27 relative to the induction coil 71 of the external input type IC card 70. The input board 27 is mainly composed of the induction coil 81 of the input board, the transmission section 22 as the communication means 21 on the input board side, the power supply device 28 of the input board, and the input section 30. In particular, the power supply 28 requires a large capacity power supply when using a method of supplying power to the IC card body 70 side.

FIG. 103 illustrates the case where FIG. 102 is performing a predetermined signal transmission operation. The predetermined signal 13 input from the input unit 30 is transmitted from the induction coil 81 of the input plate through the transmission unit 22. At this time, power 29 is also sent from the power supply 28.

FIG. 104 is a diagram of the input plate surface of the input plate 27 that serves as the input device body of the separated input device. An input device switch 11, a predetermined signal input button 41, and a display device 40 are provided on the input plate surface 86 of the input plate 27. In the case of a multi-function IC card, a function selection button 44 is provided. The thin mounting technology of the input plate 27 can be achieved by existing production technologies such as a card-type calculator or a card-type remote control operation unit. The figure does not limit the number or arrangement of operation buttons. If the vertical and horizontal shapes of the input board 27 are the same as those of the external input type IC card 70, it is convenient when the IC card is held on the back side of the input board 27.

105 is a cross-sectional view taken along line 105-105 in FIG. Since the input board 27 is often stacked with an IC card and stored in a wallet or a card compartment, a concave portion 84 of the input board is formed to prevent erroneous operation of the input board switch being pushed by mistake. At a position lower than 88, an activation switch 12D of an identification mechanism that also serves as a switch of the input plate is provided. This is an example of malfunction prevention, and there are other malfunction prevention methods such as attaching a cover or switching on when a plurality of buttons are pressed simultaneously.

FIG. 106 is the back surface of the input board 27 of FIG. The position of the induction coil 81 of the input plate 27 is indicated by a dotted line. If an induction coil is arranged in the center portion, a predetermined signal 13 can be transmitted regardless of the orientation and the front and back of the external input IC card 70 when used in an overlapping manner with the induction coil 71 of the external input IC card 70. Usability is improved. In this case, the electromagnetic wave 26 that transmits the predetermined signal 13 is generated at the center position of the input plate 27. However, the size and shape of the induction coil are not limited by the figure.

107 is a cross-sectional view taken along the line 107-107 in FIG. It shows that the electromagnetic wave 26 from the induction coil is emitted from the center.

FIG. 108 shows a state in which a predetermined signal 13 is transmitted with the external input IC card body 70 superimposed on the input board 27 of FIG. This figure shows a state in actual use, and the usage method is to push the switch 80 on the input board and input the predetermined signal 13 with the predetermined signal input button 41. There are a method of using the IC card main body 70 while being overlapped after the input of the predetermined signal 13 and a method of using the IC card alone by separating from the input plate 27. In either case, the function as an IC card does not change.

In FIG. 108, there is a gap between the input plate 27 and the IC card main body 70 to express the electromagnetic wave 26, but the input plate 27 and the IC card main body 70 may be in close contact with each other in an actual use state. By adhering to each other, a predetermined signal can be transmitted without emitting a strong electromagnetic wave. Moreover, since a strong electromagnetic wave causes information leakage of a predetermined signal, a structure capable of transmitting with a weak electromagnetic wave is used to prevent leakage. The input board and the IC card body can be carried in a card compartment etc. in a stacked state.

The thickness of the input plate 80 is not specified, but is desirably less than about 4 millimeters. Even if it overlaps with the IC card main body 70, it becomes less than 5 millimeters, and the burden when carrying is reduced.

The input plate 27 corresponds to the external input device 20 of claim 5.

FIG. 109 shows an example in which the function of the input plate 27 of the external input device 20 described in FIG. 104 of the eleventh embodiment is mounted on a mobile phone. 11 is a diagram in which a predetermined signal is input to the external input type IC card 70 described in FIG. An example of the method of use is to input a predetermined signal of the antitheft device of the present invention to the side of the mobile phone 89 equipped with the external input device, between the mobile phone 89 equipped with the external input device and the external input type IC card 70. This is transmitted to the external input IC card 70 via the electromagnetic wave 26 of the communication means 21 to make the external input IC card 70 function normally for a predetermined time.

There are various methods for communication between the portable telephone 89 equipped with the external input device and the external input type IC card 70, such as using electromagnetic waves such as radio waves, electromagnetic induction, light, etc. or by providing contact points. However, since it is necessary to prevent the transmission signal from being eavesdropped, when using electromagnetic waves, weak electromagnetic waves that cannot be communicated with each other unless the communication means 21 are brought close to each other, or have a structure that does not leak outside. It is necessary to take measures to prevent leakage such as communication using light, transmission using a contact point, and encryption of a signal.

In FIG. 109, the mobile phone 89 equipped with the external input device is separated from the external input IC card 70, but this is for explaining the electromagnetic wave 26. Prevents leakage of electromagnetic waves.

110 shows that the operation button of the cellular phone 89 is also used as the predetermined signal input button 41. FIG. Although it is an advantage of using a mobile phone that the operation buttons originally possessed by the mobile phone can be used as they are, the figure shows an example in which the switch 11 of the input device is added. If an input button for a predetermined signal is provided in the function selection of the cellular phone 89, it is not necessary to add the switch 11 of the input device. The operation method is the same as that of the input board 27 in FIG.

FIG. 111 is a schematic diagram of an electronic circuit of a mobile phone 89 on which the external input device 20 is mounted, and shows a case where a theft countermeasure device is also incorporated in the mobile phone. Therefore, there is a control means for controlling the second switch and the second switch in the electronic circuit body on the mobile phone side, and an input plate mechanism that uses a predetermined signal from the input device of the control means is mounted. .

On the other hand, FIG. 112 is an example in which an input plate mechanism is mounted on a mobile phone that does not incorporate a theft countermeasure device. Since the input plate mechanism can be used for both a power source and a predetermined signal input button of a cellular phone, the component efficiency is better than that of the input plate alone.

This embodiment is an example of the fact that the input plate does not have to be in the shape of a plate. Since the mobile phone already has a character input device, a power source, etc., it can also be used as an input device and has good mounting efficiency. A good subject.

The method of transmitting a predetermined signal to the IC card is to press the activation button 12F of the identification mechanism to activate the input device, input the predetermined signal with the input button 16E of the predetermined signal, and bring it close to the IC card and use the identification mechanism. Press the start button 12F. Although the activation button 12F of the identification mechanism is provided in the figure, a method of selecting a function at the time of execution with a function of transmitting a predetermined signal to the IC card in the function of the mobile phone may be used.

Further, by unifying the reception standard of the predetermined signal of the anti-theft device on the IC card 70 side, if there is one mobile phone or input board with a predetermined signal input function, a plurality of IC cards It can also be used as an input device for anti-theft devices mounted on motorcycles, passenger cars, etc. by unifying the reception standard of predetermined signals of anti-theft devices.

If an input device with an input board or an input board function is placed in the IC card payment device or close to the IC card payment device, the IC card possessed by the input board there when making payment Since a predetermined signal can be transmitted to an individual, there is no need for an individual to have an input board, which is publicly convenient.

FIG. 113 shows an example in which the function of the external input device is incorporated in the reading / writing device. Before the settlement, the owner of the external input type IC card 70 inputs a predetermined signal to the external input type IC card 70 using the external input device 20 installed in the reading / writing device, and places it in the transmission unit. The external input type IC card 70 is put into a state of functioning normally.

The function selection button of the external input device is effective when the IC card becomes multi-functional. As IC cards become more multi-functional, multi-function IC cards such as commuter pass functions, cash settlement functions, financial institution card functions, various key functions, and certificates will appear with a single card. . In that case, a function for selecting a function to be used at that time may be provided, and a predetermined time may be set for each function. For example, in the case of a regular ticket function, the length of a predetermined time is set to a long time such as 60 minutes or 12 hours, or the function of the regular ticket only for one hour from 8:00 am and one hour from 6:00 pm For example, the cash settlement function and the card function of the financial institution are set for a short period of 3 minutes or 10 minutes so that the function is normally performed. As a result, it is possible to prevent the payment function from being abused even if the user is stolen while being used as a regular ticket. In addition, in the case of the function of a regular ticket, the issuer also has anti-theft means.

The management of the predetermined time according to these functions is performed by the clock function of the input board and the method of mounting the clock function in the IC card main body and by the IC card side, or by the input board side and the IC card. There are ways to do it.

The present invention is defined as all objects that can be stolen because they require electronic circuits to operate and are mobile, ranging from large vehicles and ships, small to mobile phones and IC cards. It can be used as an anti-theft device for an object.
