  Incidentally, some IC tags are configured so that information stored in a storage unit can be rewritten in accordance with a signal (data) from a reader / writer device (hereinafter referred to as a rewritten IC tag).

  Consider using the rewritten IC tag in the management system described above (hereinafter referred to as an assumed management system). In this assumption management system, generally, when information input via a reader / writer device matches a pre-registered password, a person who has the authority to rewrite information stored in the storage unit of the IC tag (hereinafter referred to as a “person”). , To be an administrator). In the IC tag, information about the management target stored in the storage unit is rewritten or added according to information input by the administrator.

  However, in such an assumed management system, as long as the passwords match, even a person other than the administrator can rewrite or add information about the management target. That is, there is a possibility that information about the management target may be illegally rewritten or added by a person other than the administrator.

  If the information about the management target is illegally rewritten or added, not only the management target can be managed accurately, but also inconvenience occurs for the user of the management system (for example, a false expiration date for the product purchaser). Is informed).

  In addition, in the IC tag, information stored in the storage unit can be rewritten only once (a so-called OneWay type IC tag), or information stored in the storage unit can only be read. A read-only one (so-called ROM type IC tag) is known. If these IC tags are used in the management system described above, it is possible to reduce the information about the management target from being illegally rewritten or added.

However, these OneWay type IC tags and ROM type IC tags have a problem that information stored in the storage unit cannot be rewritten, which is inconvenient for the user.
In other words, the conventional IC tag has a problem that high security cannot be obtained while maintaining user convenience.

  Accordingly, an object of the present invention is to provide an IC tag unit that can obtain high security while maintaining convenience, and a management system using the IC tag unit.

  In order to achieve the above object, the present invention provides a storage means for storing data, a write execution means for executing control of writing data to the storage means, and a memory when a predetermined signal is received from the outside. The present invention relates to an IC tag unit including transmission / reception means for transmitting data stored in the means.

  In the IC tag unit of the present invention, when the state detection unit accepts a specific operation (for example, as described in an embodiment described later, a specific member is peeled or pulled out), the first state is When the state of the state change mechanism that changes to the second state, which is an irreversible state, is detected, and the state change mechanism switches from the first state to the second state as a result of the detection, the write control means The execution of write control by the write execution means is prohibited. However, the 1st state said here is the state of the state change mechanism before accepting specific operation.

Such a state change mechanism provided in the IC tag unit of the present invention does not return to the first state once it receives a specific operation and is changed to the second state.
Therefore, according to the IC tag unit of the present invention, when the state change mechanism is switched from the first state to the second state, the prohibition of execution of the write control is not released thereafter. Therefore, according to the IC tag unit of the present invention, after changing to the second state, it is possible to prevent the information stored in the storage unit from being rewritten and to obtain high security. Moreover, in the IC tag unit of the present invention, if the state change mechanism is in the first state before changing to the second state, information can be freely written in the storage unit, which is convenient for the user. It will be good.

That is, according to the IC tag unit of the present invention, high security can be obtained while maintaining convenience.
Furthermore, in the present invention, the write control means is configured to permit execution of the write control by the write execution means when the state change mechanism is in the first state, as described in claim 2. It is desirable that

  With the IC tag unit of the present invention configured as described above, data can be written to the storage means before a specific operation is accepted. For this reason, if the IC tag unit of the present invention is used so that the state change mechanism is changed to the second state after the necessary data is written in the storage means, the necessary data is reliably held in the storage means. Can do.

  By the way, when the state change mechanism in the present invention is composed of wiring that can be energized in the first state, as described in claim 3, in the second state, the state in which the wiring is cut or the resistance value of the wiring is It is desirable to be configured to change from one state.

  That is, even if the state change mechanism in the present invention is configured to create a state irreversible from the first state (that is, the second state) by cutting the wiring or changing the resistance value of the wiring. good.

  The state change mechanism according to the present invention may be configured to switch to the second state after a predetermined length of time has elapsed after receiving a specific operation, as described in claim 4. good.

  According to the IC tag unit configured as described above, there is a time lag from when a specific operation is received until data writing is prohibited (that is, impossible). For this reason, data can be written in the storage means of the IC tag unit until a specified time length elapses after a specific operation is applied.

  In addition, in order to configure so as to switch to the second state after a lapse of time, moisture absorption has a conductivity as a material for forming the wiring, and the resistance changes when exposed to moisture in the atmosphere. It is conceivable to use a resistance change material, an oxidation resistance change material that changes its resistance when exposed to oxygen in the atmosphere, or an evaporated conductive material that evaporates when exposed to the air.

In particular, the state change mechanism according to the present invention may be configured to include a state notification mechanism for notifying that the state has been switched from the first state to the second state.
According to the IC tag unit configured as described above, whether or not the state change mechanism has changed from the first state to the second state, that is, whether or not data can be written to the storage unit. It is possible to make the user recognize whether the state is impossible.

Note that, as described in claim 6, the state notification mechanism may be configured to notify the switch to the second state by a change in display color.
In other words, the state notification mechanism configured in this way visually notifies that the state change mechanism has been switched from the first state to the second state. As a result, the user can easily recognize that the user has switched to the second state.

In particular, if the state notification mechanism is configured using a paint that changes color when exposed to the atmosphere, the above effect can be obtained with a simple configuration.
By the way, the present invention may be implemented as a management system that manages the state of an article to which an IC tag unit is attached.

  However, in the management system of the present invention, as described in claim 7, the state management unit manages the state of the article based on the acquired data which is data transmitted from the transmission / reception unit, and the management result is The notification means needs to be configured to notify.

  Depending on the article to be managed (hereinafter referred to as “managed article”) and the item to be managed (hereinafter referred to as “managed item”), the article to which the IC tag unit is attached and the data stored in the storage means of the IC tag unit are Be changed.

  For example, the management item is whether or not a partial product of an industrial product is a managed article and the partial product is a genuine product. In this case, the state management means in the management system of the present invention, as described in claim 8, determines whether the partial product is authentic as the state of the product based on whether or not the identification data is included in the acquired data. It is desirable to be configured to manage whether or not it is a product. However, the identification data referred to here is one of data stored in the storage means of the IC tag unit, and is data preset for each partial product in order to identify the partial product.

According to the management system configured as described above, it is possible to manage whether or not a partial product is a genuine product. As a result, it is possible to reduce the use of a product other than a genuine product as a partial product.
Further, for example, a partial product of an industrial product is used as a management article, and a period during which the quality of the partial product can be guaranteed is set as a management item. In this case, the state management means in the management system of the present invention is a period in which the quality of the partial product is guaranteed as the state of the article based on the quality assurance data included in the acquired data, It is desirable to be configured to manage whether or not it is within. However, the quality assurance data mentioned here is one of data stored in the storage means, and is at least one of the date of manufacture of the partial product and the date of start of use of the partial product.

  According to the management system of the present invention configured as described above, it is possible to manage whether or not the quality of the partial product is within a period that can be guaranteed, and within the time period during which the quality of the partial product should be guaranteed. Can be recognized by the user.

  In addition, management of whether or not the quality of the partial product is within the guaranteed period may be performed by managing the manufacturing date and the time elapsed from the start date of use, and the quality is guaranteed. You may implement by managing whether the time limit (for example, date) passed has passed.

  Examples of the industrial product parts here include, for example, parts that make up automobiles (the automobiles here include plastic electric cars, etc.) and cartridges that are mounted on laser printers (or copiers). (Developing cartridge or drum cartridge), a photosensitive drum, an ink tank mounted on an ink jet printer, and the like are conceivable.

  Further, for example, a food item is a management item, and a period during which the quality of the food item can be guaranteed is a management item. In this case, the state management means in the management system of the present invention is a period in which the quality of the food product is guaranteed as the state of the article based on the quality management data included in the acquired data, as described in claim 10. It is desirable to be configured to manage whether or not it is within. However, the quality control data mentioned here is one of data stored in the storage means, and includes at least one of the date of manufacture, the expiration date, and the expiration date of the food product.

  According to the management system of this invention comprised in this way, it can be managed whether it is within the period which can guarantee the quality of foodstuffs. As a result, the user (consumer) can recognize that the quality of the food is within a guaranteed period.

  The management of whether or not the quality of the food product is within the guaranteed period may be implemented by managing whether or not the elapsed time from the date of manufacture is within the specified range, You may implement by managing whether the present date has passed the expiration date or the expiration date.

Moreover, the foodstuff said here is what a person eats, For example, in addition to a fresh foodstuff and a processed food, a pharmaceutical and a quasi-drug are included.
By the way, the IC tag unit of the present invention is attached to a physical distribution object to be distributed as described in claim 11, and the data stored in the storage means is the cargo origin of the physical distribution object, Even if it is configured to include at least one of the receiving date / time, the receiving location, the carrier, the distribution route, the distribution time, the delivery date / time, the shipping location, the vehicle, the aircraft, the railway, and the ship used for the transportation. Good.

  In the case of the IC tag unit configured as described above, the delivery record information can be acquired by reading the data in the storage means. Further, by switching the state change mechanism to the second state, it is possible to improve the reliability of the information stored in the storage means at that time.

  Further, the IC tag unit of the present invention is attached to an article as described in claim 12, and the data stored in the storage means includes information indicating a predetermined position with respect to the article. It may be configured.

In the case of the IC tag unit configured as described above, the position determined on the article can be confirmed by reading the data in the storage means.
By the way, in the IC tag unit of the present invention, if the state change mechanism is in the first state, the write control means prohibits execution of the write control by the write execution means and changes the state. When the mechanism is switched from the first state to the second state, it may be configured to permit execution of write control by the write execution means.

  In the IC tag unit configured as described above, execution of data writing control on the storage unit is prevented while the state change mechanism is in the first state, that is, until a specific operation is received.

And since the 2nd state is an irreversible state with respect to the 1st state, once the state change mechanism receives a specific operation and is changed to the 2nd state, it will not return to the 1st state. .
Therefore, according to the IC tag unit configured as described above, when the state change mechanism is switched from the first state to the second state, that is, until the timing at which data can be written is stored in the storage unit. On the other hand, it can be assured that no data is written. In other words, according to the IC tag unit of the present invention, it can be guaranteed that the IC tag unit is not used until a specific operation is accepted.

[First Embodiment]
First, FIG. 1 is a block diagram showing a schematic configuration of an information processing system 1 configured around an IC tag unit 10 to which the present invention is applied.

<Information processing system>
The information processing system 1 according to the present embodiment includes an IC tag unit 10 attached to an article, and a reader / writer device 31 that transmits and receives data to and from the IC tag unit 10. Hereinafter, an article to which the IC tag unit 10 is attached is referred to as a target article.

  Among these, the IC tag unit 10 stores data on the target article (hereinafter referred to as article information, which will be described in detail later), and transmits the stored article information in accordance with an operation command from the reader / writer device 31. The IC tag 20 is mainly configured.

The reader / writer device 31 transmits at least an operation command to the IC tag 20 and receives article information from the IC tag unit 10 by wireless communication. <About reader / writer device>
Next, the reader / writer device will be described.

  The reader / writer device 31 includes an input receiving unit 31A that receives input of information from a user, and a control unit 31B that executes processing according to the information received by the input receiving unit 31A.

  The control unit 31B is configured around a microcomputer including a CPU, a ROM, a RAM, and the like. Then, the control unit 31B sends an operation command indicating the operation content to be executed by the IC tag unit 10 to and from the IC tag unit 10 existing within a predetermined communication distance (within a communicable range) from the antenna 31C. A wireless communication process for transmitting a signal including at least is performed.

  In order to acquire the article information stored in the IC tag 20 and the write command for writing the article information to the IC tag 20 in the IC tag unit 10, the write process for transmitting the article information, and the wireless communication process. And at least one of read processes for transmitting the read command.

Here, FIG. 2 is a flowchart showing a processing procedure of a write process executed by the reader / writer device 31.
When this write process is started, as shown in FIG. 2, in S310, it is determined whether or not the article information to be stored in the IC tag 20 has been input via the input receiving unit 31A. If article information is input as a result of the determination, the process proceeds to S320.

In S320, the article information input through the input receiving unit 31A in S310 and the writing command are output through the antenna 31C.
In subsequent S330, it is determined whether or not an end command for ending the write process is input via the input receiving unit 31A. As a result of the determination, if the end command is not input, the process returns to S310, and if the end command is input, the write process is ended.

Next, the read process will be described with reference to FIG. FIG. 3 is a flowchart showing a processing procedure of read processing executed by the reader / writer device 31.
When this read process is started, a read command is transmitted via the antenna 31C in S410 as shown in FIG.

  Subsequently, it is determined whether or not the article information returned from the IC tag 20 has been acquired via the antenna 31C (S420). If the article information is not acquired as a result of the judgment, it is judged that the IC tag 20 does not exist within the communication range of the reader / writer device 31 or the article information is not returned even if it exists. , The process returns to S410, and the read command is transmitted again.

  On the other hand, if the article information has been acquired, that is, if the IC tag 20 exists within the communication range of the reader / writer device 31, the process proceeds to S430. In S430, article information processing using article information returned from the IC tag unit 10 is executed.

  Specifically, in the article information processing in the present embodiment, article information acquired from the IC tag 20 is output to an external device (not shown). However, the article information processing is not limited to this. For example, the article information may be obtained by notifying the user of the reader / writer device 31 that the article information has been obtained. The user of the reader / writer device 31 may be notified.

  In S440, it is determined whether or not an end command for ending this read process has been input. If the end command is not input as a result of the determination, the process returns to S410 and the read command is output again. On the other hand, if an end command has been input, the read process ends.

Note that the reader / writer device 31 of the present embodiment has a function (anti-collision function) capable of communicating with each communication target even when a plurality of communication targets (specifically, the IC tag unit 10) exist within the communicable range. have.
<About IC tag unit 10>
Next, the IC tag unit 10 will be described.

Here, FIG. 4 is a configuration diagram of the IC tag unit 10 attached to the target article 8.
The IC tag unit 10 includes a main body 19 that houses the IC tag 20 and an operation receiving unit 11 that receives a specific operation (hereinafter referred to as a specific operation) defined in advance from a user.

  Among these, the operation reception unit 11 is specific to the operation unit 14 for the user to perform a specific operation, the state detection sensor 12 for detecting that a specific operation has been applied to the operation unit 14, and the operation unit 14. And a notification mechanism 13 for notifying the user that an operation has been made.

The operation unit 14 includes a peeling portion 16 attached to the main body portion 19 and a pin 17 fixed to the peeling portion 16.
And the peeling part 16 consists of a thin film formed with the material which does not permeate | transmit air (especially oxygen). As shown in FIG. 5, the peeling portion 16 is formed into a long pentagon as a whole, and has a window portion 18 that is a rectangular portion formed in a colorless and transparent manner.

  The peeling portion 16 is affixed to the main body portion 19 with an adhesive having an adhesive strength that can be peeled by a human hand. However, the adhesive is not attached to one end portion (hereinafter referred to as a gripping end) 16A in the longitudinal direction of the peeling portion 16 so that the peeling portion 16 can be easily peeled from the main body portion 19. And

  The pin 17 is a member formed in a columnar shape so as to be fitted into a hole (hereinafter referred to as a fitting hole) 19 </ b> A drilled in the main body 19, and the peeling portion is interlocked with the peeling portion 16. 16 is fixed.

  That is, the operation unit 14 is configured to accept that the peeling unit 16 is peeled from the main body 19 as a specific operation. When a specific operation is received, the pin 17 fixed to the peeling portion 16 is extracted from the insertion hole 19 </ b> A when being peeled from the main body portion 19.

  Further, the notification mechanism 13 is provided on the surface 19 </ b> B of the main body 19 so as to be covered with the window 18 formed in the peeling 16 when the peeling 16 is attached to the main body 19. The notification mechanism 13, as shown in FIG. 6 (A), indicates that the background portion 13 </ b> B is coated with a paint of a prescribed color KC that is prescribed in advance, and “writable” indicates that it is in a state before receiving a specific operation. ”Display (hereinafter referred to as state information) 13 </ b> C includes a state information display portion 13 </ b> A described on the background portion 13 </ b> B.

  The paint for describing the state information 13C on the state information display unit 13A is not described in detail, but it is a color different from the specified color KC when it is not in contact with the atmosphere (especially oxygen). It is a known color that changes to the specified color KC when touched. Hereinafter, a state before receiving a specific operation is referred to as a pre-operation state, and a state after receiving a specific operation is referred to as a post-operation state.

  That is, since the notification mechanism 13 is covered with the peeling portion 16 (more precisely, the window portion 18) as shown in FIG. 6A in the pre-operation state, the state information of the state information display portion 13A is displayed. The display colors of 13C and background portion 13B are different. And when the peeling part 16 peels from the main-body part 19, the background part 13B touches air | atmosphere (oxygen), and as shown in FIG. 6 (B), the display color of the state information display part 13A and the background part 13B changes. It becomes the same specified color KC.

  In other words, the notification mechanism 13 determines whether or not the user has performed a specific operation on the operation unit 14 depending on whether the display colors of the state information display unit 13A and the background unit 13B are the same color or different. It is configured to allow the user to identify (view).

<Status detection sensor>
Here, the state detection sensor 12 will be described.
7A is a top view of the state detection sensor 12 formed around the insertion hole 19A of the main body 19 as viewed from above the insertion hole 19A, and FIG. 7B shows the state detection sensor 12 inserted. It is the side view seen from the side of hole 19A.

  As shown in FIG. 7, the state detection sensor 12 includes two terminals 12A and B protruding from the main body 19 into the insertion hole 19A, and a connection line 12C for connecting the two terminals 12A and B. I have.

  The connecting wire 12C is made of a linear member having conductivity, and is formed so as to protrude from the tip of the terminal 12A into the fitting hole 19A. The connection line 12C is bent with the tip of the terminal 12A as a base point by the pin 17 being inserted into the insertion hole 19A, and contacts the terminal 12B. However, the connection line 12C is formed so that the connection strength with the terminal 12A is such that the connection line 12C drops from the terminal 12A when the pin 17 is pulled out from the insertion hole 19A.

That is, the state detection sensor 12 is in a low impedance state in which the terminals 12A and 12B and the connection line 12C are connected in the pre-operation state (that is, the first state of the present invention, hereinafter referred to as an energized state). . In the post-operation state, the connection line 12C is disconnected from the terminals 12A and 12B (ie, the second state of the present invention, hereinafter referred to as a disconnected state). Moreover, the state in which the connection line 12C is disconnected from the terminals 12A and 12B (that is, the disconnected state) is an irreversible state from the state in which the connection line 12C is connected between the terminals 12A and 12B (that is, the energized state).
<About IC tag>
Next, the IC tag will be described.

Here, FIG. 8 is a block diagram showing a schematic configuration of the IC tag.
As shown in FIG. 8, the IC tag 20 includes a transmission / reception unit 22 that transmits / receives a signal (electromagnetic wave) to / from the reader / writer device 31 via the transmission / reception antenna 21, and an electromotive force according to the signal received by the transmission / reception unit 22. And a power supply unit 23 for supplying power to each unit constituting the IC tag 20. Furthermore, the IC tag 20 includes a storage unit 24 that stores article information, and a processing unit 25 that controls the units 22, 23, and 24 constituting the IC tag 20 in accordance with an operation command from the reader / writer device 31. .

Among these, the memory | storage part 24 consists of non-volatile memories (for example, EEPROM etc.) which can preserve | save the memory content even if power supply is interrupted | blocked and can rewrite the memory content.
Further, the processing unit 25 is configured mainly with a microcomputer having at least a CPU. Further, the state detection sensor 12 is connected to the processing unit 25.
<Operation of the processing unit>
Next, the operation of the processing unit 25 will be described.

Here, FIG. 9 is a flowchart showing an operation procedure of the processing unit 25.
The processing unit 25 is activated when the transmission / reception unit 22 receives a signal (more precisely, an operation command) from the reader / writer device 31 and power supply from the power supply unit 23 is started. Hereinafter, the operation command that has triggered the processing unit 25 is referred to as the current operation command.

In the operation of the processing unit 25, as shown in FIG. 9, it is first determined whether or not the write prohibition flag has been set (S110).
This write prohibition flag indicates that data writing to the storage unit 24 is prohibited if set, and if cleared, data writing to the storage unit 24 is permitted. It represents that.

  If the write prohibition flag has not been set as a result of the determination in S110, the process proceeds to S120, and in accordance with the detection signal from the state detection sensor 12, it is determined whether or not the peeling part 16 has been peeled from the main body part 19. to decide.

  Specifically, if the detection signal from the state detection sensor 12 is in a state where the terminals 12A and 12B are conductive (that is, low impedance), it is determined that the peeling portion 16 is not peeled off from the main body portion 19. . On the other hand, if the detection signal is a state in which the terminals 12A and 12B are not conductive (that is, high impedance), it is determined that the peeling portion 16 has been peeled from the main body portion 19.

As a result of the determination in S120, if the peeling part 16 is peeled from the main body part 19, a write prohibition flag is set (S130), and then the process proceeds to S140.
That is, the write prohibition flag is set when the operation command from the reader / writer device 31 is first received after the peeling unit 16 is peeled from the main body 19.

  If the write prohibition flag is already set as a result of the determination in S110, it is assumed that the operation command from the reader / writer device 31 has been received a plurality of times after the peeling unit 16 has been peeled off from the main body unit 19. Determination is made, and the process proceeds to S140 while the write prohibition flag is set. If the result of determination in S120 is that the peeling part 16 has not been peeled off, the process proceeds to S140 while keeping the write prohibition flag unset.

  In subsequent S140, it is determined whether or not the current operation command is a write command. As a result of the determination, if the current operation command is a write command, it is determined in S150 whether or not a write prohibition flag has been set.

  If the write prohibition flag is cleared as a result of the determination in S150, the article information transmitted from the reader / writer device 31 is written in the storage unit 24, and then the operation of the processing unit 25 is terminated. That is, if the peeling unit 16 is not peeled from the main body unit 19, the processing unit 25 updates the article information stored in the storage unit 24 to the latest article information, or updates the storage unit 24 with the latest article information. Or add.

After that, it waits until the next operation command is input.
On the other hand, if the write prohibition flag is set as a result of the determination in S150, the article information transmitted from the reader / writer device 31 is discarded and the operation of the processing unit 25 is terminated. That is, if the peeling unit 16 has been peeled off, writing control to the storage unit 24 is prohibited.

After that, it waits until the next operation command is input.
By the way, as a result of the determination in S140, if the current operation command is not a write command, the process proceeds to S170.

  In S170, it is determined whether or not the current operation command is a read command. If the result of this determination is that the current operation command is a read command, the article information stored in the storage unit 24 is read in S180. Then, the article information read from the storage unit 24 is output to the transmission / reception unit 22. Then, the transmission / reception unit 22 transmits the article information read from the storage unit 24 to the reader / writer device 31.

Thereafter, the operation of the processing unit 25 is terminated, and the process waits until the next operation command is input.
On the other hand, if it is determined in S170 that the current operation command is an operation command other than the read command, that is, the current operation command is other than the write command or the read command (for example, the operation of the IC tag 20 is tested. If it is a check command, etc.), the process proceeds to S190. In S190, control according to the current operation command (for example, if it is a check command, a check operation for checking whether the IC tag 20 operates normally) is executed. Thereafter, the operation of the processing unit 25 is terminated, and the process waits until the next operation command is input.

  In other words, when the IC tag 20 receives an operation command from the reader / writer device 31, the processing unit 25 is activated and executes control of contents according to the received operation command. Then, the processing unit 25 normally transmits the article information stored in the storage unit 24 to the reader / writer device 31 if the operation command is a read command.

  On the other hand, if the operation command is a write command, the article information transmitted from the reader / writer device 31 is stored in the storage unit 24. However, even if the operation command is a write command, if the write prohibition flag is set, the operation of the processing unit 25 is terminated without storing the article information transmitted from the reader / writer device 31.

[Effect of the first embodiment]
As described above, in the IC tag 20 of the present embodiment, the operation unit 14 receives a specific operation from the user (individually, the peeling unit 16 is peeled from the main body unit 19), and the state detection sensor 12 is high. When the impedance is reached, writing of the article information received from the reader / writer device 31 into the storage unit 24 is prohibited. The IC tag 20 may be configured not to receive the article information from the reader / writer device 31 instead of the process of writing the article information to the storage unit 24 when the state detection sensor 12 becomes high impedance. good.

  The high impedance is such that once the peeling portion 16 is peeled off, the connection line 12C is dropped from the terminals 12A and 12B, or the connection line 12C is disconnected, and the energization is impossible. It is an irreversible state with the energized state before peeling from the part 19.

  Therefore, according to the IC tag 20 of the present embodiment, when the peeling part 16 is peeled from the main body part 19, the prohibition of execution of the writing control is not released thereafter. Therefore, according to the IC tag unit 10 of the present embodiment, it is possible to prevent the writing to the storage unit 24 from being executed after receiving the peeling unit 16 from the main body unit 19 as a specific operation.

As a result, it is possible to provide the IC tag unit 10 capable of obtaining high security while improving convenience.
Moreover, in the IC tag unit 10 of this embodiment, when the peeling part 16 is peeled from the main body part 19, the state information display part 13A changes to the same color as the background color.

  For this reason, according to the IC tag unit 10 of this embodiment, it is meaningful to the user's vision whether the IC tag unit 10 is in a state where writing control can be executed or is impossible. It is praised by the information I have. As a result, the user can easily recognize that switching to a state in which writing to the storage unit 24 is impossible without learning how to use the IC tag unit 10 by using character information. Although it is impossible, it is possible to reduce erroneous operations such as erroneous execution.

[Modification of First Embodiment]
Although the first embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and can be implemented in various modes without departing from the gist of the present invention. .

  For example, in the IC tag unit 10 of the above-described embodiment, the state detection sensor 12 and the connection line 12C are composed of a wire material that drops from the terminal 12A when the connection line 12C is pulled out of the insertion hole 19A. However, the configuration of the state detection sensor 12 and the connection line 12C is not limited to this.

  As shown in FIG. 10, the state detection sensor 112 has terminals 112A and 112B protruding into a recess 119A formed in the main body 19, and is attached to the back surface of the peeling portion 116 and is a conductive thin film. 112D may be configured to function as the connection line 12C.

In this case, the thin film 112D needs to be fixed at a position where the thin film 112D contacts the terminals 112A and 112B protruding into the recess 119A while the peeling portion 16 is stuck to the main body portion 19.
Further, in the IC tag unit 10 in the above embodiment, whether or not data writing to the storage unit 24 is prohibited is expressed using the write prohibition flag, but data writing to the storage unit 24 is not performed. The method of indicating whether or not prohibited is not limited to this. For example, the processing unit 25 may be provided with a latch circuit that maintains a signal indicating that (for example, low level) when the peeling unit 16 is peeled off. The writing to the storage unit 24 may be prohibited while the signal is maintained.

  Further, for example, when the IC tag 20 includes a data bus between the processing unit 25 and the storage unit 24 for writing and reading, the peeling unit 16 is separated from the main body unit 19. When peeled off, the data bus for writing may be cut off. That is, the IC tag 20 may be configured to physically disable data writing when a specific operation is accepted.

  Further, in the IC tag unit 10 in the above embodiment, as a power supply method of the IC tag 20, when a signal from the reader / writer device 31 is received, an electromotive force generated by the received signal is transmitted to each part constituting the IC tag 20. Although the passive method of supplying is used, the power supply method may be an active method of supplying each part from a power source (battery) mounted on the IC tag 20.

[Second Embodiment]
Next, as a second embodiment of the present invention, a target article management system configured using the information processing system 1 in the first embodiment will be described.

Here, FIG. 11 is a block diagram showing a schematic configuration of the target article management system of the present embodiment.
<About the target article management system>
The target article management system 70 manages the state of products purchased by consumers at the retail store, the number of products sold (hereinafter referred to as product status, etc.) and settles all products purchased by consumers. belongs to.

  Therefore, the target article management system 70 acquires the IC tag unit 110 attached to each product, the light device 71 for writing article information to the IC tag unit 110, and the article information written in the IC tag unit 110. In addition, a plurality of cash registers 30 for settlement of purchased merchandise and a server 72 for storing article information necessary for settlement are provided.

  Among these, since the IC tag unit 110 is the same as that described in the first embodiment, each part constituting the IC tag unit 110 is the same as each part constituting the IC tag unit 10 in the first embodiment. The description here is omitted.

  The write device 71 is the reader / writer device 31 configured to be able to execute only the write process described in the first embodiment. For this reason, about each part which comprises the light apparatus 71, the code | symbol same as each part which comprises the reader / writer apparatus 31 in 1st Embodiment is attached | subjected, and description here is abbreviate | omitted.

  The article information written in the storage unit 24 of the IC tag 20 by the light device 71 includes at least identification information for identifying a product (hereinafter referred to as product identification information).

  In particular, when the product is a food product, in addition to the product identification information, the date of manufacture of the food product, the name of the manufacturer of the food product, the expiration date or the expiration date of the food product are included as product information. Yes. In addition, the foodstuff in this embodiment includes a pharmaceutical, a quasi-drug, and a specific health food in addition to so-called fresh food and processed food.

  In the present embodiment, the IC tag unit 110 is used by being attached to a product or a container for packaging the product (hereinafter referred to as a product). As a form of attaching the IC tag unit 110 to a product or the like, the IC tag unit 110 may be formed in a sheet shape and attached to the product or the like, or the IC tag unit 110 may be formed in a chip shape and the product or the like. You may embed in.

  When the IC tag unit 110 is attached, the store clerk of the retail store identifies the product via the input receiving unit 31A of the light device 71 if the target article is a product other than food (for example, clothing or household goods). Only information is input as article information. On the other hand, if the target article is a food product, product identification information, production date / time, manufacturer name, and expiration date (or expiry date) are input as article information via the input receiving unit 31A of the light device 71.

  Then, the light device 71 is caused to execute a write process, and the article information is stored in the storage unit 24 of the IC tag 20. Then, the store clerk of the retail store peels the peeling portion 16 of the IC tag unit 110 from the main body portion 19 and attaches the IC tag unit 110 from which the peeling portion 16 has been peeled off to a product or the like.

  In other words, the IC tag unit 110 attached to a product or the like has the peeling portion 16 peeled off from the main body portion 19, and article information is stored in the storage portion 24 of the IC tag 20.

In addition, the server 72 is a well-known computer mainly composed of a well-known microcomputer having at least a ROM, a RAM, and a CPU, and a storage device.
The storage device of the server 72 stores, for each product, product identification information and the type of product (hereinafter referred to as the product) corresponding to the product identification information (for example, whether the product is a food product). And the sales price of the product are stored in association with each other.

Hereinafter, information in which product identification information is associated with a sales price is referred to as sales information. This sales information is changed as needed by a store clerk at a retail store or the like.
<About cash register>
Next, a cash register machine will be described.

  Each of the cash registers 30 outputs a read command for the IC tag 20 by wireless communication, acquires the article information from the IC tag unit 110, and the article information acquired by the lead apparatus 33. And an information processing device 35 that manages the state of the product and the like and settles the total amount of the product purchased by the consumer.

Among these, the read device 33 is the reader / writer device 31 configured to be able to execute only the read process described in the first embodiment.
That is, in the present embodiment, the information processing system 1 described in the first embodiment is configured by the IC tag unit 110 attached to a product or the like and the lead device 33.

  On the other hand, the information processing device 35 is configured around a known microcomputer 35A having at least a ROM, a RAM, and a CPU, and includes an operation unit 35B and a notification unit 35C.

  Among these, the operation part 35B receives the input of information according to the operation from the outside. The notification unit 35C includes a display unit that displays an image in accordance with a signal from the microcomputer 35A, and an audio output unit that outputs audio in accordance with a signal from the microcomputer 35A.

  That is, the information processing device 35 is configured such that the microcomputer 35A executes processing according to the processing program. And the microcomputer 35A which comprises the information processing apparatus 35 performs the adjustment process for adjusting those goods sales while managing goods state etc. FIG.

Here, FIG. 12 is a flowchart showing the procedure of the settlement process.
This settlement process is executed by the microcomputer 35A of the information processing device 35 when the information processing device 35 is activated.

  Then, as shown in FIG. 12, when the checkout process is activated, it is determined whether or not article information is input from the lead device 33 in S720. If the article information is not input as a result of the determination, the process waits until it is input. On the other hand, when the article information is input, the process proceeds to S730.

  That is, when the IC tag 20 attached to a product or the like passes through the communication range of the lead device 33, the article information acquired by the lead device 33 from the IC tag 20 is input to the information processing device 35.

  In S730, it is determined whether or not the product identification information included in the product information (hereinafter referred to as product information) input in S720 indicates that the product is food, that is, the product is food. It is judged whether it is a product. If it is determined that the product is a food product, the process proceeds to S740.

  In S740, it is determined whether or not the current date has passed the expiration date currently included in the article information. If it is determined that the current date / time has not passed the expiration date, the process advances to step S750.

  Furthermore, in S750, it is determined whether or not the time length from the current date and time to the best before date (hereinafter referred to as a guarantee period) is less than a predetermined time length. As a result of the determination, if the guaranteeable period is less than the specified time length, it is determined whether or not the product is a discount target, and the process proceeds to S760.

In S760, a discount rate for the product is determined based on the guarantee period, and the process proceeds to S770.
In the present embodiment, in accordance with a discount rate map in which the length of the guaranteeable period and the discount rate are associated with each other so that the discount rate for the product increases stepwise as the guaranteeable period is shorter. decide. For example, in the discount rate map, the guarantee period is 20% to 29 days, the discount rate is 10%, and the guarantee period is 10 days to 19 days, the discount rate is 20%. A discount period of 30% is set for the period from the 0th to the 9th possible period.

  By the way, as a result of the determination in S730, if the product is not food (for example, if the product is clothing or household goods), the process proceeds from S740 to S770 without executing S760. Also, as a result of the determination in S750, when the guaranteeable period is equal to or longer than the specified time length, the process proceeds to S770. In other words, if it is not necessary to discount the selling price of the product from the selling price, the process proceeds to S770 without executing S760.

In S770, the sales amount (so-called selling price) of the product is calculated.
In this embodiment, a price obtained by multiplying the sales price of the product stored in the server 72 by the discount rate determined in S760 (more precisely, 1-discount rate / 100) is calculated as the sales amount. . However, if a negative determination is made in S730 or S750 (ie, without going through S760) and the process proceeds to S770, the selling price itself for the product stored in the server 72 is calculated as the selling price (ie, , The discount rate is 0).

  Subsequently, the sales amount calculated in S770 of the current cycle is added to the integrated value of the sales amount calculated up to the previous cycle (S780), and the process proceeds to S800. That is, in S780, the sales amount is totaled for all the products that the consumer plans to purchase.

By the way, as a result of the determination in S740, if the current date has passed the expiration date, the process proceeds to S790.
In S790, the notification section 35C is notified that the expiration date of the product has expired and the product is inappropriate as a sales target. That is, in S790, the audio output unit outputs that the expiration date of the product has passed, and displays an image indicating that fact on the display unit. Then, the process proceeds to S800.

  Further, in S800, it is determined whether or not a payment command for determining the number of items sold and the sales amount has been input via the operation unit 35B. If the settlement instruction is not input as a result of the determination, the process returns to S720. If the settlement instruction is input, the process proceeds to S810.

  In S810, the sales number and sales price of the product determined in S790 are stored in the server 72, and the sales number and sales price are printed on the receipt. That is, it settles about the goods which consumers purchased.

Thereafter, the process returns to S720 and waits until new article information is acquired.
In other words, in the checkout process, the product information acquired from the IC tag 20 is checked against the information in the server 72 to determine whether the product is food and the expiration date has expired. Furthermore, if the expiration date has not expired for the product, it is determined whether or not it is a discount target. If the product is a discount target, the sales amount is automatically discounted.
[Effects of Second Embodiment]
As described above, in the target article management system 70 of the present embodiment, the article information written on the IC tag 20 is not illegally rewritten when products or the like are arranged at the storefront. Therefore, the consumer can purchase the product etc. with peace of mind according to the information that can be acquired from the IC tag unit 110 attached to the product etc.

In particular, according to the settlement process in the present embodiment, a product whose expiration date has expired is notified at the time of settlement, so that it is possible to prevent a product whose expiration date has expired from being sold by mistake.
In addition, according to the checkout process in the present embodiment, since the food product whose expiration date is approaching is automatically discounted, it is not necessary to operate the discount button once at a time as in the past. For this reason, it is possible to prevent the store clerk at the retail store from forgetting the discount on the product.
[Modification of Second Embodiment]
As mentioned above, although 2nd Embodiment of this invention was described, this invention is not limited to the said embodiment, In the range which does not deviate from the summary of this invention, it is possible to implement in various aspects. .

  For example, in the above embodiment, attaching the IC tag unit 110 to a product or the like is performed at a retail store or the like. However, attaching the IC tag unit 110 to a product or the like is performed by a manufacturer that manufactures the product or the like. You may carry out when shipping etc.

  In the checkout process in the above embodiment, if the product is a food item in S740, it is determined whether the expiration date of the food item has expired. In S740, whether the expiration date has expired. It may be determined whether or not.

  In the above embodiment, the lead device 33 and the information processing device 35 are connected by a dedicated connection line. However, the lead device 33 may be connected to the information processing device 35 by a general-purpose connection line. It may be good or connected by radio.

  The target article management system 70 may be used for inventory management of merchandise. That is, if the IC tag unit 110 is attached to a target article that does not need to be rewritten or added, and the information is acquired from the IC tag unit 110, the application location is any. It may be something like this.

[Third Embodiment]
Next, a third embodiment of the present invention will be described.
The information processing system in the third embodiment is different from the information processing system 1 in the first embodiment only in the configuration of the state detection sensor of the IC tag unit.

For this reason, the same reference numerals are given to the same components as those in the first embodiment, and the description thereof will be omitted. The configuration of the state detection sensor different from that in the first embodiment will be mainly described.
<About the operation reception unit>
Here, FIG. 13 is an explanatory diagram showing a configuration of the operation receiving unit 11 centering on the state detection sensor in the present embodiment.

  The state detection sensor 212 of the present embodiment includes terminals 212A and 212B protruding into a recess 219A formed in the main body 19, and a state change substance 212E disposed in the recess 219A so as to contact both terminals 212A and 212B. It consists of.

  Although the detailed description is omitted, the state change material 212E is made of an electrically conductive conductive material that evaporates when exposed to the atmosphere, and is configured to function as the connection line 12C.

[Effect of the third embodiment]
If such a state change material 212E (that is, an evaporated conductive material) is used as the connection line 12C, the time during which the terminals 212A and 212B can be energized can be increased by increasing the amount of the evaporated conductive material disposed in the recess 219A. Can be lengthened. That is, in the IC tag unit including the state detection sensor 212 configured as described above, after a specific operation (here, the peeling part 16 is peeled off from the main body part 19) is applied, the terminals 212A and 212B are connected to each other. It takes time before it becomes impossible to energize. In other words, according to such an IC tag unit, a time lag can be provided from when a specific operation is performed until data cannot be written to the storage unit 24.

[Modification of Third Embodiment]
The third embodiment of the present invention has been described above, but the present invention is not limited to the above embodiment, and can be implemented in various modes without departing from the gist of the present invention. .

  For example, the connection line 12C in the above embodiment is configured such that when the peeling portion 16 is peeled off, the terminals 12A and B (or 212A and B) are not energized. It may be configured such that the resistance changes when 16 is peeled off. That is, in the state detection sensor 12 (212), when the resistance value of the connection line 12C is changed from a predetermined resistance value by a predetermined limit or more, the separation unit 16 is separated from the main body unit 19 and the processing unit 25 is It may be configured to determine.

  In this case, the state change substance 212E arranged in the recess 219A formed in the main body 19 needs to be used as the connection line 12C. Moreover, as the state-changing substance 212E, it has conductivity, and when it touches moisture in the atmosphere, it changes its resistance when it touches moisture in the atmosphere (potassium chloride or magnesium chloride) or oxygen in the atmosphere. It is necessary to use one of the oxidation resistance changing substances whose resistance changes.

[Fourth Embodiment]
Next, as a fourth embodiment of the present invention, a target article management system configured using the information processing system 1 in the third embodiment will be described.

Here, FIG. 14 is a block diagram showing a schematic configuration of the target article management system of the present embodiment.
<About the target article management system>
The target article management system 80 determines the replacement timing of consumable parts used in an image forming apparatus that forms an image on a recording medium (for example, a document) based on print data input from the outside. It is for management.

  For this reason, the target article management system 80 writes the article information to the IC tag unit 210 attached to each of the specific components constituting the image forming apparatus, and the article information to the IC tag unit 210. A reader / writer device 83 and an information processing device 82 for managing the replacement time based on information acquired by the reader / writer device 83 are provided.

  Among them, the IC tag unit 210 and the reader / writer device 83 are the same as those described in the third embodiment, and therefore, each part constituting the IC tag unit 210 and the reader / writer device 83 has a third embodiment. The same reference numerals are assigned to the components constituting the IC tag unit and the reader / writer device in the embodiment, and the description thereof is omitted here.

In the present embodiment, the reader / writer device 83 and the information processing device 82 constituting the target article management system 70 are incorporated in the image forming apparatus.
An image forming apparatus in which the reader / writer device 83 and the information processing device 82 are incorporated includes a scanner unit that forms an electrostatic latent image on a photosensitive drum, a process cartridge for executing an image forming process, and an image on a recording medium. It is configured as a well-known laser printer including a fixing unit for fixing the toner.

  Among these, the process cartridge is a cartridge having a structure for performing charging, development, transfer, and cleaning (cleaning of the photoconductor) as an image forming process, and is detachably attached to the main body of the image forming apparatus. . The process cartridge includes a drum cartridge and a developing cartridge that is a developing device that is detachably attached to the drum cartridge.

That is, the drum cartridge contains a photosensitive drum, a charger, a transfer roller, and the like, and the developing cartridge contains toner that is a nonmagnetic developer. As is well known, the quality of these drum cartridges and developing cartridges deteriorates depending on the number of times images are formed on the recording medium and the passage of time. That is, these cartridges are consumable parts that are required to be replaced at an appropriate timing.
<Information processing device>
Next, the information processing apparatus 82 will be described.

  The information processing device 82 is configured around a known microcomputer 82A having at least a ROM, a RAM, and a CPU, and includes an auxiliary storage device (for example, HDD), an operation unit 82B, and a notification unit 82C.

  Among these, the operation part 82B receives the input of information according to the operation from the outside. The notification unit 82C includes a display unit that displays an image according to a signal from the microcomputer 82A, and an audio output unit that outputs sound according to a signal from the microcomputer 82A.

  In this embodiment, the microcomputer 82A constituting the information processing apparatus 82 manages whether or not the target article is a genuine product and whether or not the target product is within the quality assurance period. Execute.

  In this embodiment, the drum cartridge and the developing cartridge are shipped with the IC tag unit 210 attached. That is, the IC tag unit 210 is used by being attached to a drum cartridge or a developing cartridge as a target article. Hereinafter, the cartridge to which the IC tag unit 210 is attached is referred to as the cartridge.

  Then, the user of the image forming apparatus peels the peeling portion 16 of the IC tag unit 210 from the main body portion 19 and attaches the cartridge to which the IC tag unit 210 from which the peeling portion 16 has been peeled is attached to the image forming apparatus. .

At this time, the reader / writer device 83 is caused to execute a write process, and the article information is stored in the storage unit 24 of the IC tag 20.
In the present embodiment, the article information stored in the storage unit 24 of the IC tag 20 includes an identification code for identifying the image forming apparatus to which the cartridge is attached and the cartridge attached to the image forming apparatus. It includes at least mounting date and time that is date and time (here, date). The identification code consists of a character string (numerical string) within a range defined in advance for each image forming apparatus, and is stored in the storage device of the information processing apparatus 35.

Here, FIG. 15 is a flowchart showing a processing procedure of the partial product management processing.
This partial product management process is executed by the microcomputer 82A of the information processing apparatus 35 when the information processing apparatus 35 is activated (in this embodiment, when the image forming apparatus is activated).

  Then, when the partial product management process is started, first, in S905, it is determined whether or not article information is input from the reader / writer device 83. If the article information is not input as a result of the determination, the process proceeds to S910.

  In S910, an elapsed time (hereinafter referred to as a first elapsed time) since article information was previously input or since the partial product management process was activated is a predetermined time (that is, a length of time) defined in advance. It is determined whether this is the case. As a result of the determination, if the first elapsed time is less than the predetermined time, the process returns to S905. On the other hand, as a result of the determination in S910, if the first elapsed time is equal to or longer than the predetermined time, it is determined that the IC tag unit 210 is not attached to the drum cartridge or the developing cartridge, that is, the cartridge is an unauthorized product. Then, the process proceeds to S915.

  In S915, a signal for informing that the use of the unauthorized product is stopped is output to the notification unit 82C. Then, the voice output unit outputs a voice message that prompts the user to stop using the illegal product, and the display unit displays an image that prompts the user to stop using the illegal product. Then, the process returns to S905.

By the way, when article information is input in S905, that is, when article information is acquired from each of the cartridges, the process proceeds to S920.
In subsequent S920, an identification code (hereinafter referred to as an acquisition code) in the article information input from the reader / writer device 83 in S905 is checked against the registered code. However, the registered code referred to here is an identification code stored in the image forming apparatus in advance.

  In S930, it is determined whether or not the acquired code matches the registered code as a result of checking in S920. As a result of the determination, if the currently acquired code matches the registered code, the process proceeds to S950.

  In S950, it is determined whether or not an elapsed time (hereinafter referred to as a second elapsed time) after the cartridge is mounted on the image forming apparatus is within a predefined use limit period. Here, the use limit time limit is the length of time during which the quality of the cartridge can be guaranteed after the cartridge is mounted on the image forming apparatus.

  Further, as a specific method for determining whether or not the second elapsed time is within the use limit time limit, a time length obtained by subtracting the mounting date and time included in the article information from the current date and time (that is, If the difference) is smaller than the use limit time limit, it is considered that the second elapsed time is within the use limit time limit.

  As a result of the determination in S950, if the second elapsed time is within the use limit time limit, the process returns to S905. And it waits until new article information is input. This is because the cartridge is a genuine product, and at the present time, the quality of the cartridge can be guaranteed, and there is no inconvenience in continuing the use of the cartridge.

  On the other hand, as a result of the determination in S950, if the second elapsed time exceeds the use limit time limit, the process proceeds to S960. In such a case, the cartridge is a genuine product, but the quality of the cartridge cannot be guaranteed, or the developed cartridge is a remanufactured product in which only the developer (toner) is repacked once again. This is because it can be judged.

  As a result of the determination in S930, if the acquired code does not match the registered code, that is, it is determined that the currently used cartridge is an illegal product, and the process proceeds to S960. The fraudulent product here refers to a cartridge or a remanufactured product to which an IC tag different from the IC tag unit 210 (for example, an IC tag whose identification code is not stored in the storage unit 24) is attached.

  In S960, a signal for informing that the cartridge is to be replaced with a genuine product with a guaranteed quality (hereinafter referred to as a new cartridge) is output to the notification unit 82C. Then, the audio output unit outputs by voice that the cartridge should be replaced with a new cartridge, and the display unit displays an image indicating that the cartridge should be replaced with a new cartridge. Then, the process returns to S905 and waits until new article information is input.

That is, in the partial product management process of this embodiment, whether or not the cartridge is a genuine product based on whether or not the product information can be acquired or whether or not the product information includes identification data. To manage. At the same time, in the partial product management process of the present embodiment, whether or not the quality of the partial product can be guaranteed is managed based on the mounting date and time included in the article information.
[Effect of Fourth Embodiment]
As described above, in the target article management system 80 according to the present embodiment, the article information written in the IC tag 20 when the cartridge is mounted on the image forming apparatus can be illegally rewritten when the image forming apparatus is used. Can be prevented.

  In particular, according to the partial product management process in the present embodiment, when an unauthorized product is used in the cartridge, the unauthorized product continues to be used in the cartridge in order to notify the user that the unauthorized product should be stopped. Can be reduced.

  Furthermore, according to the partial product management process in the present embodiment, it is possible to determine whether or not a time limit for guaranteeing the quality of the cartridge has passed since the cartridge was mounted on the image forming apparatus. Then, according to the partial product management process of the present embodiment, if the time limit for guaranteeing the quality of the cartridge has passed, the cartridge quality can be guaranteed to prompt the user to replace the cartridge with a new one. It becomes possible to keep it.

As a result, the quality of image formation by the image forming apparatus can be guaranteed.
Furthermore, in the present embodiment, the target article management system using the IC tag unit 210 having a time lag from when the specific operation is received until the writing to the storage unit 24 is prohibited (that is, in the third embodiment). 80, the article information can be written in the storage unit 24 after the cartridge is mounted on the image forming apparatus.
[Modification of Fourth Embodiment]
Although the fourth embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and can be implemented in various modes without departing from the gist of the present invention. .

  For example, in the partial product management process in the above embodiment, if the cartridge is an unauthorized product, in S915, the use of the unauthorized product is urged to be stopped, and in S960, the cartridge is to be replaced with a new cartridge. Although the notification is made, if the cartridge is an improper product, in S915 or S960, a process for stopping the use of the image forming apparatus may be executed.

  Further, in the partial product management process in the above embodiment, when the cartridge is a recycled product, a notification that prompts the user to perform component replacement is executed after a predetermined time has elapsed since the cartridge is mounted on the image forming apparatus. Also good.

  In the above embodiment, the target article management system 80 is constructed using the cartridge of the image forming apparatus as the target article. However, the industrial product to which the target article management system 80 is applied is not limited to the image forming apparatus. For example, a battery unit (for example, a laptop computer, a digital camera, a digital video camera, a power-assisted bicycle, an electric vehicle, or the like) may be used as the target article.

  Furthermore, the industrial product that is the target article by the target article management system 80 may be an automobile configured by combining a plurality of partial products. When the target article management system 80 is applied to an automobile, many parts (for example, tires, seats, navigation devices, bumpers, spoilers, etc.) constituting the automobile or mounted on the automobile will be described below. Each may be a target article. That is, when the target article management system 80 is applied to an automobile, the IC tag unit 210 is attached to each automobile component.

  An automobile to which the target article management system 80 is applied may be an automobile equipped with an internal combustion engine (gasoline engine or diesel engine) as a power generation source, or a fuel cell (so-called fuel cell car) and a motor (so-called electricity). A vehicle equipped with an automobile) or a vehicle equipped with both an internal combustion engine and a motor (a so-called hybrid vehicle) may be used.

When the target article management system 80 is applied to an automobile, the reader / writer device 83 and the information processing device 82 need to be incorporated in the automobile.
In such a case, the microcomputer constituting the information processing apparatus 82 needs to execute a partial product management process for managing whether or not the target article is a genuine product (so-called genuine product). Furthermore, in order to execute the partial product management process, the identification information defined in advance for each vehicle for identifying the vehicle and the use of the vehicle component are used as the article information stored in the storage unit 24 of the IC tag 20 It is necessary to include at least the start date and time.

  Note that the partial product management process when the target article management system 80 is applied to an automobile has been described in the fourth embodiment except that S950 is omitted from the partial product management process described in the fourth embodiment. It may be the same as the partial product management process.

  As described above, when the target article management system 80 is applied to a car, it is possible to notify the user whether or not the car component is a genuine product (for example, a misuse or stolen product is an IC). Since the tag unit 210 is not attached or the identification code is different from the identification code of the own vehicle, it is notified as an unauthorized product). For this reason, according to the partial product management process of this embodiment, it is possible to reduce the use of unauthorized parts.

  Further, when the target article management system 80 is applied to a vehicle in this way, in the partial product management process, the user is notified of the replacement time of the vehicle component parts. Parts can be replaced and the car can be maintained in an appropriate state. In particular, if the IC tag unit 210 is attached to a timing belt or a storage container that stores engine oil, and those automobile components (that is, the timing belt and engine oil) are targeted, the replacement time of the consumable parts is It can be recognized by automobile users.

  In addition, if the target article management system 80 is configured using the IC tag unit 210 having a time lag from when the specific operation is accepted until writing to the storage unit 24 is prohibited (that is, in the third embodiment), When the automobile is shipped from the factory, the peeling part 16 is peeled off from the main body part 19, and the article information can be stored in the storage part 24 when the automobile is delivered from the dealer to the user.

Hereinafter, modifications to the first to fourth embodiments will be described.
In the IC tag 20 (more precisely, the processing unit 25) of the above embodiment, when the peeling unit 16 is peeled from the main body unit 19 (that is, a specific operation is accepted), data writing to the storage unit 24 is prohibited. However, the processing unit 25 may be configured such that data writing to the storage unit 24 is permitted when a specific operation is accepted.

  That is, when it is detected from the output of the state detection sensor 12 that the peeling unit 16 has been peeled off from the main body unit 19, the processing unit 25 sets a flag that permits writing of data to the storage unit 24. Before the flag is set, writing of data to the storage unit 24 may be prohibited. That is, if the state detection sensor 12 is in the energized state, the IC tag 20 is prohibited from writing data to the storage unit 24 and triggers that the state detection sensor 12 is switched to the non-connection state. As an alternative, data writing to the storage unit 24 may be permitted.

According to the IC tag unit 10 configured in this way, when the peeling part 16 is peeled from the main body part 19, no data is stored in the storage part 24, that is, the IC tag unit 10 is unused. Can be guaranteed.
[Correspondence between Embodiment and Claims]
Finally, the relationship between the descriptions of Embodiments 1 to 4 and the claims will be described.

  The storage unit of the IC tag 20 in the above embodiment corresponds to the storage unit of the present invention, the transmission / reception unit of the IC tag 20 corresponds to the transmission / reception unit of the present invention, and the state detection sensor 12 of the IC tag unit 10 corresponds to the present invention.

[Fifth Embodiment]
Next, a fifth embodiment of the present invention will be described.
<Configuration of delivery record management system>
FIG. 16 shows a schematic configuration diagram of the delivery record management system 301 of the present embodiment. The delivery record management system 301 is a system used by a delivery company or the like to record a distribution route relating to a physical distribution object 302 such as mail, parcel, cargo, registered mail or the like.

  This delivery record management system 301 is used in an IC tag unit 310 attached to a physical distribution object 302, a light device 320 disposed in various places in the distribution process of the physical distribution object 302, an office of a delivery company, and the like. The reader device 330 is disposed, and a server 340 that can communicate with the reader device 330 is provided.

  As shown in FIG. 17, the IC tag unit 310 of the present embodiment has a sheet shape having a description column 315 in which information such as an address is described as a delivery slip, and includes a pasting part 311 and a peeling part 312. 313 is connected. The cut line 313 is for easily separating the sticking portion 311 and the peeling portion 312 and is formed by, for example, a perforation.

  The back surface 311A (the back surface of the surface provided with the description column 315 shown in FIG. 17) of the pasting part 311 is pasted to the physical distribution object 302 with an adhesive or the like. On the other hand, the back surface 312A of the peeling portion 312 is such that only a part of the corner (corner portion 314) of the IC tag unit 310 is bonded to the physical distribution object 302 and can be easily peeled off from the physical distribution object 302.

Further, the IC tag 20 </ b> A is disposed on the back surface 312 </ b> A of the peeling portion 312 (or inside the peeling portion 312).
As shown in FIG. 18, the IC tag 20A includes a transmission / reception unit 22A for transmitting / receiving a signal (electromagnetic wave) between the light device 320 and the reader device 330 via the transmission / reception antenna 21A, and a signal received by the transmission / reception unit 22A. And a power supply unit 23A that generates an electromotive force and supplies power to each unit constituting the IC tag 20A. Further, the IC tag 20 </ b> A is in accordance with the storage unit 24 </ b> A for storing article information (information relating to delivery of the physical distribution object 302, details will be described later), and operation commands from the light device 320 and the reader device 330. And a processing unit 25A for controlling the units 22A, 23A, and 24A constituting 20A.

Among these, the storage unit 24A includes a non-volatile memory (for example, an EEPROM or the like) that retains the stored contents even when the power supply is cut off and that can rewrite the stored contents.
Further, the processing unit 25A is configured mainly with a microcomputer having at least a CPU.

  Further, the processing unit 25A is connected to both ends of the state detection wiring 26 (foil wiring). The state detection wiring 26 constitutes a part of the circuit of the processing unit 25A. In a state where the state detection wiring 26 can be energized, article information can be written to the storage unit 24A in response to a write command from the light device 320, but processing is performed when the state detection wiring 26 is disconnected. Part of the part 25A is destroyed and article information cannot be written to the storage part 24A.

As shown in FIG. 17, the state detection wiring 26 is arranged so as to straddle the cut line 313 on the back surface of the pasting part 311 and the peeling part 312.
Here, when the peeling part 312 is connected to the sticking part 311, the state detection wiring 26 can be energized, so that article information can be written to the IC tag 20 </ b> A. On the other hand, in the state where the peeling part 312 is separated from the sticking part 311, the state detection wiring 26 is disconnected, so that the article information cannot be written to the IC tag 20 </ b> A.

16 transmits at least an operation command to the IC tag 20A by wireless communication.
The light device 320 has the same configuration as the reader / writer device 31 shown in FIG. 1, and processes according to the information received by the input receiving unit 320A and the input receiving unit 320A that receives input of information from the user. The control part 320B which performs is provided. The article information to be stored in the IC tag 20A is received by the input receiving unit 320A.

  The control unit 320B is configured around a microcomputer including a CPU, a ROM, a RAM, and the like. Then, the control unit 320B performs a later-described write process of transmitting a write command for writing article information to the IC tag 20A existing within a predetermined communication distance (within a communicable range) from the transmission / reception antenna 320C.

  Also, the reader device 330 shown in FIG. 16 transmits at least an operation command for the IC tag 20A and receives article information from the IC tag 20A by wireless communication.

  The reader device 330 has basically the same configuration as the light device 320, and includes an input receiving unit 330A, a control unit 330B, and a transmission / reception antenna 330C. The control unit 330B performs a read process, which will be described later, to acquire article information stored in the IC tag 20A existing within a predetermined communication distance (within a communicable range) from the transmission / reception antenna 330C. The article information acquired by the read process is transmitted to the server 340.

The server 340 is a well-known server mainly composed of a well-known microcomputer 340A having at least a ROM, a RAM, and a CPU, and a storage device 340B.
The storage device 340B of the server 340 has a management database. In this management database, article information about each physical distribution object 302 is stored.

Note that the light device 320 and the reader device 330 according to the present embodiment have a function (anti-antimeter) capable of communicating with each communication target even when a plurality of communication targets (specifically, the IC tag unit 310) exist within the communicable range. Collision function).
<Operation of delivery record management system>
The operation of the delivery record management system 301 will be described based on the flowchart of FIG. The delivery record management system 301 of the present embodiment writes article information to the IC tag 20A at the time of receiving, delivery process, and delivery (writing by write processing using the write device 320).

  First, as step 1 (hereinafter, step is described as S), article information is written into the IC tag 20A when a predetermined recording timing is reached. In subsequent S2, it is determined whether or not the writing in S1 is the final writing. If it is not the final writing, the process returns to S1. On the other hand, if it is final writing, the process proceeds to S3.

  Specific examples of S1 and S2 are given. First, as S1, when the delivery company receives the physical distribution object 302 (first recording timing), the light device 320 is used to indicate each of the goods source, the receiving date and time, the receiving place, and the physical distribution object type as the article information. Information is written to the IC tag 20A. Since the writing here is not the final writing, S2 is NO, and S1 is executed again at the next recording timing.

  Next, as the second S1, in the delivery process (next recording timing) of the accumulation center or the like that accumulates the physical distribution objects 302, the light device 320 is used as the article information and the vehicle (or aircraft, ship) used for transportation. , Railway), carrier, current location (distribution route), and current date and time (distribution time) are written in the IC tag 20A. Since the writing here is not the final writing, S2 is NO.

  Next, as S3 for the third time, before delivery (the last recording timing), the write device 320 is used, and as the article information, the delivery date / time, delivery location, and delivery person information are stored in the IC tag 20A. Write.

  Since the writing is the final writing, the process proceeds to the state change operation in S3. In this embodiment, an operation for peeling the peeling portion 312 is performed. As a result, the state detection wiring 26 is disconnected, and thereafter writing to the IC tag 20A becomes impossible. After this work, the physical distribution object 302 is delivered to the destination.

Next, in S4, the IC tag 20A that has completed the state change work is managed. In this embodiment, the information of the IC tag 20A brought back to the delivery company's office or the like is read by the reader device 330 (reading by the read process) and stored in the management database of the server 340.
<Processing by light device>
The processing procedure of the write process executed by the write device 320 will be described based on the flowchart shown in FIG.

  In this write process, first, in S510, it is determined whether or not the article information to be stored in the IC tag 20A is input via the input receiving unit 320A. If the article information is input to the light device 320 as a result of the determination, the process proceeds to S520.

In S520, the article information input through the input receiving unit 320A in S510 and the writing command are output to the IC tag 20A through the transmission / reception antenna 320C.
In subsequent S530, it is determined whether or not an end command for ending the write process is input via the input receiving unit 320A. As a result of the determination, if the end command is not input, the process returns to S510, and if the end command is input, the write process is ended.
<Processing by reader device>
The processing procedure of the read process executed by the reader device 330 will be described based on the flowchart shown in FIG.

When this read process is started, as shown in FIG. 21, a read command is transmitted to IC tag 20A via transmission / reception antenna 330C in S540.
In subsequent S550, it is determined whether or not the article information returned from IC tag 20A has been acquired via transmission / reception antenna 330C. If the article information is not acquired as a result of the judgment, it is judged that the IC tag 20A does not exist within the communication range of the reader device 330, or the article information is not returned even if it exists. Returning to S540, the read command is transmitted again.

On the other hand, if the article information is acquired, that is, if the IC tag 20A exists within the communication range of the reader device 330 and the IC tag 20A returns the article information, the process proceeds to S560. In S560, the article information transmitted from the IC tag 20A is output to the server 340. Thereafter, the read process is terminated.
<Processing by IC tag>
The processing procedure of the IC tag control process executed by the processing unit 25A of the IC tag 20A will be described based on the flowchart shown in FIG.

  The processing unit 25A is activated when power supply from the power supply unit 23A is started when the transmission / reception unit 22A receives a signal (more precisely, an operation command) from the light device 320 or the reader device 330. .

In the operation of the processing unit 25A, as shown in FIG. 22, it is first determined whether or not the write prohibition flag has been set (S610).
As a result of the determination in S610, if the write prohibition flag has not been set, the process proceeds to S620, and it is determined whether or not the state change work has been completed. The state change work in the present embodiment is a work for separating the peeling portion 312 from the sticking portion 311. As described above, when the peeling unit 312 is separated from the pasting unit 311, a part of the circuit of the processing unit 25 </ b> A is disconnected, so that the article information cannot be written due to the hardware configuration of the IC tag 20 </ b> A.

  In S620, if the state detection wiring 26 can be energized, it is determined that the above operation is not performed, and if the state detection wiring 26 is not energizable, it is determined that the above operation has already been performed.

If the result of determination in S620 is that state change work has been completed, a write prohibition flag is set (S630), and then processing proceeds to S640.
That is, the write prohibition flag is set when an operation command is first received from the write device 320 or the reader device 330 after the state detection wiring 26 is disconnected.

  If the write prohibition flag is set, it indicates that the state detection wiring 26 is disconnected and writing of data (article information, etc.) to the storage unit 24A is impossible due to hardware configuration. If not, it indicates that data can be written to the storage unit 24A in terms of hardware configuration.

Further, in the state where the write prohibition flag is set, not only writing of article information but also writing of control software and application software is prohibited.
As a result of the determination in S610, if the write prohibition flag has been set, the process proceeds to S640. If the result of determination in S620 is that state change work has not yet been performed, the process proceeds to S640 while the write prohibition flag is not set.

  In subsequent S640, it is determined whether or not the received operation command is a write command from write device 320. If the operation command is a write command as a result of the determination, it is determined in S650 whether or not the write prohibition flag has been set.

  As a result of the determination in S650, if the write prohibition flag has not been set, the article information transmitted from the writing device 320 is written in the storage unit 24A (S660), and the process is terminated. Then, it waits until the next operation command is input.

  On the other hand, as a result of the determination in S650, if the write prohibition flag has already been set, the article information transmitted from the light device 320 is discarded and the process is terminated. After that, it waits until the next operation command is input.

By the way, as a result of the determination in S640, if the received operation command is not a write command, the process proceeds to S670.
In S670, it is determined whether the operation command is a read command from reader device 330 or not. If the result of this determination is that the operation command is a read command, the article information stored in the storage unit 24A is read in S680. Then, the article information read from the storage unit 24A is output to the transmission / reception unit 22A. Then, the transmission / reception unit 22A transmits the article information read from the storage unit 24A to the reader device 330. Thereafter, this process is terminated, and the process waits until the next operation command is input.

  On the other hand, if the result of determination in S670 is that the operation command is something other than a write command or a read command (for example, a check command for testing the operation of the IC tag 20A), the process proceeds to S690. In S690, control according to the operation command (for example, if it is a check command, a check operation for checking whether the IC tag 20A operates normally) is executed. Thereafter, this process is terminated, and the process waits until the next operation command is input.

  That is, in the IC tag 20A, when an operation command is received from the light device 320 or the reader device 330, the processing unit 25A is activated and executes control of contents according to the received operation command. Then, the processing unit 25A usually transmits the article information stored in the storage unit 24A to the reader device 330 if the operation command is a read command.

On the other hand, if the operation command is a write command, the article information transmitted from the light device 320 is stored in the storage unit 24A. However, even if the operation command is a write command, if the write prohibition flag is set, the operation of the processing unit 25A is terminated without storing the article information transmitted from the light device 320.
[Effect of Fifth Embodiment]
As described above, in the delivery record management system 301 of the present embodiment, after the physical distribution object 302 is delivered to the destination, that is, the state where the peeling part 312 is separated from the sticking part 311 and the state detection wiring 26 is disconnected. In the hardware configuration, the article information cannot be written. Therefore, even if a means for ignoring write prohibition on the control software is used, writing cannot be executed, so that it is possible to suppress unauthorized rewriting of article information written on the IC tag 20A. Can improve the reliability.

Further, since the article information is stored in the IC tag 20A, only the device for inputting information (the light device 320) needs to be present at the recording timing. In the conventional system, the physical distribution object 302 cannot hold the article information, or even if the article information can be held, the contents may be altered. It is necessary to read information (or simply identification information) and collate and register it in the online database, and it is necessary to place a system connected to the online database at each recording timing location. Since the system is not necessary, convenience is improved.
[Modification of Fifth Embodiment]
Although the fifth embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and can be implemented in various modes without departing from the gist of the present invention. .

For example, in the above-described embodiment, the configuration in which the recording timing is three points at the time of receiving, at the time of delivery, and at the time of delivery is exemplified, but it may be performed at timings other than these.
Moreover, in the said embodiment, although the structure which adhere | attaches the IC tag unit 310 to the physical distribution target object 302 with the adhesive agent was illustrated, it is not limited to the structure.

  For example, when commodities such as vegetables and livestock are assumed as the physical distribution object 302, an IC tag unit 350 shown in FIG. The IC tag unit 350 includes an IC tag 20B having a configuration similar to that of the IC tag 20A, and is configured to be attached to the physical distribution object 302 with a binding band 351.

  The IC tag unit 350 is divided into a main part 352 including a binding band 351 and a separation part 353. By bending the separation part 353 and performing separation (performing a state change operation), the state detection wiring 26B is disconnected, and the IC tag 20B. Writing to is disabled. In addition, a display unit 354 is provided which indicates that writing cannot be performed by bending.

In the IC tag unit 350, since the IC tag 20B is arranged on the main part 352 side, the IC tag 20B can be left in the product.
When this IC tag unit 350 is used, the article information is only written to the IC tag 20B in the transportation / distribution stage, and the IC tag 20B is written by separating the separation unit 353 at the stage where the physical distribution object 302 is passed to the final consumer. Disallowed and handed to the consumer along with the physical distribution object 302.

  As a result, since the IC tag 20B is delivered to the consumer, the consumer can see the information on the IC tag 20B and know the product producer information, shipping information, and distribution information. Improve satisfaction and increase product value. Further, since the consumer cannot modify the stored content, the reliability of the information of the IC tag 20B is increased and unnecessary trouble can be avoided.

It should be noted that confirmation of information on the IC tag 20B by the consumer may be executed by a mobile phone or the like having a tag reader / writer function.
Note that after the separation unit 353 is separated, writing may be performed until a predetermined time elapses. It is conceivable to use an air battery for setting the predetermined time. For example, when the separation part 353 is cut off, the sealing of the air battery is peeled off, and while the air battery power generation continues, a predetermined electric circuit is maintained with the power generated by the power generation, and while the electric circuit is maintained It may be configured to enable writing to the IC tag 20B.

  In addition to the above, it is conceivable to configure the IC tag unit as shown in FIG. The IC tag unit 360 includes a main part 361 including an IC tag 20C having the same configuration as the IC tag 20A, and a seal-like separating part 362 that can be peeled off from the main part 361.

  In this IC tag unit 360, the back surface 361A of the main portion 361 (the back surface of the surface 361B displayed in FIG. 23B) is an adhesive surface and can be attached to the physical distribution object 302. When the separation part 362 is peeled off from the main part 361 (the state change operation is performed), the state detection wiring 26C is disconnected and writing to the IC tag 20C becomes impossible. Although not shown, it is shown that writing is impossible on the surface after the separation part 362 is peeled off.

In the delivery record management system using the IC tag unit 360 configured as described above, the same effects as those of the IC tag unit 350 shown in FIG. 23A can be obtained.
In addition to the above, a configuration as shown in FIG. This IC tag unit 370 has a double-layered seal, and includes a base seal 371 attached to the physical distribution object 302 and a surface seal 372 attached to the upper surface of the base seal 371. .

  The adhesive of the base seal 371 is strong, and is configured such that the base seal 371 is torn when the attached one is peeled off. The adhesive material of the surface seal 372 is configured to be relatively weak.

  An IC tag 20D having the same configuration as the IC tag 20A is disposed on the lower surface 371A of the base seal 371. Further, when the surface seal 372 is peeled off, the state detection wiring 26D is disconnected, and writing to the IC tag 20D becomes impossible.

  In the delivery record management system using the IC tag unit 370 configured as described above, not only when the surface seal 372 is peeled off but also when the base seal 371 is peeled off, the base seal 371 is broken and the state detection wiring 26D. Is disconnected, and writing to the IC tag 20D becomes impossible. Therefore, the fact that the IC tag unit 370 that has been pasted is pasted because the base seal 371 is damaged or the IC tag 20D cannot be written can be easily identified. It is possible to prevent disguise by pasting it.

  By the way, in the said embodiment and modification, when a state change operation | work is performed, an IC tag unit will isolate | separate, the piece which has an IC tag, and the piece which does not have an IC tag (a piece which has only a part of disconnected state detection wiring) However, it may be configured such that a part of the constituent elements other than the state detection wiring is separated from the main part of the IC tag by the state change operation. For example, a chip used only for writing article information may be separated from the main part of the IC tag.

  Moreover, in the said embodiment and modification, after performing the state change operation | work which isolate | separates an IC tag unit in order to prevent writing to an IC tag, an IC tag is arrange | positioned only to either one isolate | separated However, the IC tag may be arranged on both.

  For example, it may be configured as an IC tag unit 380 shown in FIG. The IC tag unit 380 assumes a product such as a brand product as the physical distribution object 302.

  The IC tag unit 380 includes a consumer tag 381 and a store tag 382, and includes IC tags 20E and 20F, respectively. The IC tags 20 are connected to each other by a state detection wiring 26E. When the consumer tag 381 and the store tag 382 are peeled off, the state detection wiring 26E is disconnected and writing to the IC tags 20E and 20F becomes impossible. It is configured as follows. In addition, it is shown on the mating surface between the consumer tag 381 and the store tag 382 that writing is impossible when this surface is seen.

  The IC tag unit 380 stores information such as a manufacturing location and a serial number in a manufacturing factory, stores information indicating a transportation route in a distribution process, and stores information such as a sales date, a store name, and a purchaser name. Remember. The same information may be stored in the consumer tag 381 and the store tag 382, or different information may be stored in part or all.

  Then, at the time of sale, the consumer tag 381 and the store tag 382 are peeled off, the consumer tag 381 is delivered to the purchaser together with the product, and the store tag 382 is managed (registered in the database) at the store.

  In the delivery record management system using the IC tag unit 380 configured as described above, the purchaser obtains a consumer tag 381 that stores information on distribution channels. Since this consumer tag 381 is in a state in which writing to the IC tag 20E is not possible, the quality assurance function can be enhanced by increasing the credibility of the information.

In addition, since the IC tag in which the distribution channel and the like are recorded passes to both the purchaser and the store, it can be used for later verification, which is convenient.
In addition, although the configuration in which the state detection wiring 26E is wired so as to connect the IC tag 20E of the consumer tag 381 and the IC tag 20F of the store tag 382 is illustrated, different state detection wirings are provided for each IC tag. It may be configured so that when the consumer tag 381 and the store tag 382 are peeled off, any state detection wiring is disconnected and writing to any IC tag is disabled.
[Sixth Embodiment]
Next, a sixth embodiment of the present invention will be described.
<Configuration of the book management system>
FIG. 25 shows a schematic configuration diagram of the book management system 401 of the present embodiment.

  The book management system 401 is used when books are managed in a library or the like, and can communicate with the IC tag unit 410, the reader / writer device 420, and the reader / writer device 420 that are attached to the book 402 and used. A server 430 and a reader device 440 are provided.

  Since the IC tag unit 410 of this embodiment has the same configuration as the IC tag unit 360 shown in FIG. 23B, description will be made using the reference numerals shown in FIG. The IC tag unit 410 has an IC tag 20C, and is configured such that book information (classification number, serial number, etc.) can be written on the front surface 361B of the main part 361. The IC tag 20C executes an IC tag control process described later. As shown in FIG. 18, the IC tag 20C includes a transmission / reception antenna 21C, a transmission / reception unit 22C, a power supply unit 23C, a storage unit 24C, a processing unit 25C, and a state detection wiring 26C similar to the IC tag 20A.

  A reader / writer device 420 shown in FIG. 25 is a device that transmits and receives data to and from the IC tag unit 410 by wireless communication, and includes an input receiving unit 420A that receives input of information from a user, and an input receiving unit. And a control unit 420B that executes processing according to the information received at 420A.

  The control unit 420B is mainly configured of a microcomputer including a CPU, a ROM, a RAM, and the like. Then, the control unit 420B performs an operation command indicating the operation content to be executed by the IC tag unit 410 with the IC tag unit 410 existing within a predetermined communication distance (within a communicable range) from the transmission / reception antenna 420C. Wireless communication processing for transmitting a signal including at least.

As the wireless communication process, the reader / writer device 420 executes, for example, a write process shown in FIG. 20, a read process shown in FIG. 21, and an inventory process shown in FIG.
A reader device 440 shown in FIG. 25 is a device that transmits and receives data to and from the IC tag unit 410 by wireless communication. The reader / writer device 420 has an input reception unit 420A, a control unit 420B, and a transmission / reception antenna 420C. The input receiving unit 440A, the control unit 440B, and the transmission / reception antenna 440C having the same functions as the above. Furthermore, it has the display screen 441 which displays information based on the instruction | command from the control part 440B. For example, the reader device 440 executes a search process shown in FIG.

The server 430 is a well-known server mainly composed of a well-known microcomputer 430A having at least a ROM, a RAM, and a CPU, and a storage device 430B.
The storage device 430B of the server 430 has a book management database. In the book management database, article information about the book 402 is stored. The article information in this embodiment is identification information for identifying an individual book 402, classification information, a book name, an author name, and an outline. In addition, the book management database stores a book shelf and identification information of the book 402 arranged on the book shelf in association with each other.

Note that the reader / writer device 420 and the reader device 440 of this embodiment can communicate with each communication target even when a plurality of communication targets (specifically, the IC tag unit 410) exist within the communicable range ( Anti-collision function).
<Operation of the book management system>
(1) Attachment of IC tag unit to book The flow of attachment of the IC tag unit 410 to the book 402 will be described based on the flowchart of FIG.

  First, as S1, when the predetermined recording timing is reached, article information is written into the IC tag 20C of the IC tag unit 410 (write processing by the reader / writer device 420). In subsequent S2, it is determined whether or not the writing in S1 is the final writing. If not the final writing, the process returns to S1. On the other hand, if it is final writing, the process proceeds to S3.

  The predetermined recording timing in this embodiment includes timing for recording the formal classification (identification information, classification information, book title, author name) of the book 402, timing for recording specialized information (summary), and the like.

  For example, as S1, the librarian writes information indicating the formal classification of the book 402 to the IC tag 20C. Since the writing here is not the final writing, S2 is NO, and S1 is executed again at the next recording timing.

  Next, as S1 for the second time, the specialist librarian writes the outline information of the book to the IC tag 20C. Since the writing is the final writing, the process proceeds to the state change operation in S3. In this embodiment, an operation of separating the separation part 362 shown in FIG. 23B from the main part 361 is performed. As a result, the state detection wiring 26C is disconnected, and thereafter, writing to the IC tag 20C becomes impossible.

  Next, in S4, the IC tag 20C that has completed the state change work is managed. In this embodiment, the information of the IC tag 20 </ b> C is read by the reader / writer device 420 (read processing by the reader / writer device 420) and stored in the book management database of the server 430.

Thereafter, the book 402 is placed on a predetermined bookshelf. Note that the IC tag unit 410 may be attached to the book 402 at any timing.
(2) Operation at the time of library inventory Explaining the operation at the time of library inventory inspection (when checking whether a library exists correctly).

  Using the reader / writer device 420, article information is acquired from all IC tag units 410 attached to a book 402 existing in a predetermined range (for example, one book shelf). A specific process of the reader / writer device 420 here will be described in an inventory process described later.

Next, the acquired article information is compared with the information in the book management database stored in the server 430 to check whether the books 402 arranged on the bookshelf match or not.
After that, the books 402 to be stored in other bookshelves are moved, and the missing books 402 are determined as investigation targets. The article information referred to here includes the identification information of the book 402, and the book shelf (position) where the book 402 should be placed can be found by collating with the book management database. That is, the identification information is also information indicating a position.
(3) Operation when using the library Explain the operation of users who use the library.

  Search information such as classification information and keywords is input to the reader device 440. Next, using the reader device 440, article information is acquired from all or a part of the IC tag units 410 attached to the book 402 existing in a predetermined range (for example, one book shelf).

  The reader device 440 extracts the book 402 that matches the classification information and the book 402 including the book name, the author name, and the keyword input in the summary, and outputs the book 402 to the display screen 441 of the reader device 440. Specific processing of the reader device 440 here will be described in search processing described later.

Further, when information is read from the IC tag unit 410 for one book 402, information that is permitted to be browsed among the information stored in the IC tag 20C is output to the display screen 441.
<Processing by reader / writer device>
A processing procedure of write processing executed by the reader / writer device 420 will be described based on a flowchart shown in FIG.

  In this write process, first, in S510, it is determined whether or not the article information to be stored in the IC tag 20C has been input via the input receiving unit 420A. If the article information is input to the reader / writer device 420 as a result of the determination, the process proceeds to S520.

In S520, the article information input via the input receiving unit 420A in S510 and the writing command are output to the IC tag 20C via the transmission / reception antenna 420C.
In the subsequent S530, it is determined whether or not an end command for ending the write process is input via the input receiving unit 420A. As a result of the determination, if the end command is not input, the process returns to S510, and if the end command is input, the write process is ended.

Next, the processing procedure of the read processing executed by the reader / writer device 420 will be described based on the flowchart shown in FIG.
When this read process is started, as shown in FIG. 21, in S540, a read command is transmitted to the IC tag 20C via the transmission / reception antenna 420C.

  In subsequent S550, it is determined whether or not the article information returned from IC tag 20C has been acquired via transmission / reception antenna 420C. If the article information is not acquired as a result of the judgment, it is judged that the IC tag 20C does not exist within the communication range of the reader / writer device 420, or the article information is not returned even if it exists. , The process returns to S540, and the read command is transmitted again.

  On the other hand, if the article information is acquired, that is, if the IC tag 20C exists within the communication range of the reader / writer device 420 and the IC tag 20C returns the article information, the process proceeds to S560. In S560, the article information transmitted from the IC tag 20C is output to the server 430. Thereafter, the read process is terminated.

Next, the processing procedure of the inventory process executed by the reader / writer device 420 will be described based on the flowchart shown in FIG.
This inventory process is started when an input for performing inventory is made to the input receiving unit 420A of the reader / writer device 420. In this process, first, information is received in S565. Specifically, it receives the identification number of the bookshelf to be invented, which is input by the input receiving unit 420A.

  The subsequent processes of S570 and S575 are the same as the processes of S540 and S550 described in FIG. If the article information is acquired in S575, that is, if the IC tag 20C exists in the communication range of the reader device 440 and the IC tag 20C returns the article information, the process proceeds to S580. .

  In subsequent S580, it is determined whether or not an operation for finishing reading has been input to input receiving unit 420A. If the above operation has not been input, the process returns to S570. On the other hand, if the above operation has been input, the process proceeds to S585.

In subsequent S585, article information is output. Specifically, the article information acquired until the operation to finish reading is input is output to the server 430. Thereafter, this process is terminated. After that, the server 430 refers to the book management database and collates with the article information of the book 402 arranged on the bookshelf that has been inventoried. Information is output to a display or the like.
<Processing by reader device>
A processing procedure of search processing executed by the reader device 440 will be described based on a flowchart shown in FIG.

  This search process starts when an input for performing a search is made to the input receiving unit 440A. In this process, first, information is received in S565. Specifically, the search information input by the input receiving unit 440A is received.

  The subsequent processes of S570 and S575 are the same as the processes of S540 and S550 described in FIG. If the article information is acquired in S575, that is, if the IC tag 20C exists in the communication range of the reader device 440 and the IC tag 20C returns the article information, the process proceeds to S580. .

  In subsequent S580, it is determined whether or not a read end operation is input to input receiving unit 440A. If the above operation has not been input, the process returns to S570. On the other hand, if the above operation has been input, the process proceeds to S585.

In subsequent S585, article information is output. Specifically, based on the acquired article information, the title of the book 402 having article information that matches the search information is output to the display screen 441. Thereafter, this process is terminated.
<Processing by IC tag>
The processing procedure of the IC tag control processing executed by the IC tag 20C will be described based on the flowchart shown in FIG. The processing unit 25C included in the IC tag 20C is supplied with power from the power supply unit 23C when the transmission / reception unit 22C receives a signal (more precisely, an operation command) from the reader / writer device 420 or the reader device 440. It will be activated.

As shown in FIG. 22, the processing unit of the IC tag 20C first determines whether or not the write prohibition flag has been set (S610).
As a result of the determination in S610, if the write prohibition flag has not been set, the process proceeds to S620, and it is determined whether or not the state change work has been completed. The state change work in the present embodiment is a work of separating the separation part 362 from the main part 361 in the IC tag 20C. As described above, when the separation part 362 is disconnected from the main part 361, the state detection wiring 26C is disconnected, that is, a part of the circuit of the processing part is disconnected. Therefore, the article information is written on the hardware configuration of the IC tag 20C. It becomes impossible.

  In S620, if the state detection wiring 26C can be energized, it is determined that the above operation is not performed, and if the state detection wiring 26C is not energizable, it is determined that the above operation has already been performed.

If the result of determination in S620 is that state change work has been completed, a write prohibition flag is set (S630), and then processing proceeds to S640.
That is, when the operation command from the reader / writer device 420 or the reader device 440 is first received after the state detection wiring 26C is disconnected, the write prohibition flag is set.

  If this write prohibition flag is set, it indicates that the state detection wiring 26C is disconnected, and writing of data (article information, etc.) to the storage unit 24C is impossible due to hardware configuration. If not, it indicates that data can be written to the storage unit 24C in terms of hardware configuration.

Further, in the state where the write prohibition flag is set, not only writing of article information but also writing of control software and application software is prohibited.
As a result of the determination in S610, if the write prohibition flag has been set, the process proceeds to S640. If the result of determination in S620 is that state change work has not yet been performed, the process proceeds to S640 while the write prohibition flag is not set.

  In subsequent S640, it is determined whether or not the received operation command is a write command from the reader / writer device 420. If the operation command is a write command as a result of the determination, it is determined in S650 whether or not the write prohibition flag has been set.

  As a result of the determination in S650, if the write prohibition flag has not been set, the article information transmitted from the reader / writer device 420 is written in the storage unit 24C (S660), and the process is terminated. Then, it waits until the next operation command is input.

  On the other hand, as a result of the determination in S650, if the write prohibition flag has been set, the article information transmitted from the reader / writer device 420 is discarded, and the present process is terminated. After that, it waits until the next operation command is input.

By the way, as a result of the determination in S640, if the received operation command is not a write command, the process proceeds to S670.
In S670, it is determined whether or not the read command is from reader / writer device 420 or reader device 440. If the result of this determination is that the operation command is a read command, the article information stored in the storage unit 24C is read in S680. Then, the article information read from the storage unit 24C is output to the transmission / reception unit 22C. Then, the transmitting / receiving unit 22C transmits the article information read from the storage unit 24C to the reader / writer device 420 or the reader device 440 that is the source of the read command. Thereafter, this process is terminated, and the process waits until the next operation command is input.

On the other hand, if the result of determination in S670 is that the operation command is something other than a write command or a read command (for example, a check command for testing the operation of the IC tag 20C), the process proceeds to S690. In S690, control according to the operation command (for example, if it is a check command, a check operation for checking whether the IC tag 20C operates normally) is executed. Thereafter, this process is terminated, and the process waits until the next operation command is input.
[Effects of Sixth Embodiment]
As described above, in the book management system 401 according to the present embodiment, the article information written in the IC tag 20C of the IC tag unit 410 attached to the book 402 can be prevented from being illegally rewritten. Can improve the reliability.

In addition, since information can be collected and searched from a plurality of books 402 at a time, books can be easily searched and inventoryed.
Further, detailed information such as an outline of the book 402 can be read by the reader device 440 and referred to.
[Modification of Sixth Embodiment]
The sixth embodiment of the present invention has been described above, but the present invention is not limited to the above embodiment, and can be implemented in various modes without departing from the gist of the present invention. .

For example, in the above-described embodiment, a system for managing books has been exemplified. However, the present invention can also be used for inventory, etc. in the scene of managing rental items and equipment.
[Seventh Embodiment]
Next, a seventh embodiment of the present invention will be described.
<Admission system configuration>
FIG. 27 shows a schematic configuration diagram of the entrance system 501 of the present embodiment. The entrance system 501 is a system used in a facility that uses a ticket to enter.

  The admission system 501 includes an IC tag unit 510 used as a ticket, an admission machine 520 installed at an entrance of a facility, and a server 530 that can communicate with the admission machine 520.

  As shown in FIG. 28A, the IC tag unit 510 is formed in a sheet shape, and a first piece 511 and a second piece 512 are connected via a cut line 513. The cut line 513 is for easily separating the first piece 511 and the second piece 512, and is formed by perforations, for example. An IC tag 20G is arranged inside the first piece 511.

  As with the IC tag 20A shown in FIG. 18, the IC tag 20G includes a state detection wiring 26G, a transmission / reception antenna, a transmission / reception unit, a power supply unit, a storage unit, a processing unit, and the like (not shown). In accordance with an operation command from a reader / writer device 521 described later, article information is written to and read from the storage unit. Note that the article information in the present embodiment corresponds to identification information of the IC tag unit 510 stored in advance, admission date information input by the admission machine 520 at the time of admission, and admission machine information.

  The state detection wiring 26G constitutes a part of the circuit of the processing unit. In a state where the state detection wiring 26G can be energized, article information can be written to the storage unit in response to a write command from the reader / writer device 521, but processing is performed when the state detection wiring 26G is disconnected. Part of the part is destroyed, and article information cannot be written to the storage part.

As shown in FIG. 28A, the state detection wiring 26G is disposed so as to straddle the cut line 513 inside the first piece 511 and the second piece 512.
Here, when the first piece 511 and the second piece 512 are connected, since the state detection wiring 26G can be energized, the article information can be written to the IC tag 20G. On the other hand, in a state where the first piece 511 and the second piece 512 are separated, the state detection wiring 26G is disconnected, and thus writing of article information to the IC tag 20G becomes impossible.

In addition, as shown in FIG. 27, the entrance machine 520 includes a reader / writer device 521, an entrance ticket processing device 522, and a control device 523.
The reader / writer device 521 includes a transmission / reception antenna 521A, a control unit 521B, and the like, and can acquire an operation command (write command, read command) for the IC tag 20G and article information returned in response to the read command. It is configured.

  As shown in FIG. 28 (B), the admission ticket processing device 522 is a device that conveys the IC tag unit 510 inserted into the ticket entrance 524 of the entrance machine 520 to the ticket exit 525, and the process of the conveyance Then, the second piece 512 is cut out and stored, and each process by the reader / writer device 521 is performed.

  Returning to FIG. The control device 523 controls the reader / writer device 521 and the admission ticket processing device 522, and is a known microcomputer mainly composed of a memory and a known microcomputer having at least a ROM, a RAM, and a CPU. It is.

In addition, the server 530 is a well-known computer mainly composed of a well-known microcomputer having at least a ROM, a RAM, and a CPU, and a storage device.
The storage device of the server 530 has an entrance management database. The admission management database stores article information read from the IC tag 20G by the reader / writer device 521.
<Processing by entrance machine>
The procedure of the entrance process by the control device 523 of the entrance machine 520 will be described based on the flowchart shown in FIG. This process starts when the IC tag unit 510 is inserted into the ticket slot 524.

First, in S1010, the reader / writer device 521 performs a read process, which will be described later, and reads the article information of the IC tag unit 510 stored in the IC tag 20G.
Subsequently, in S1012, it is determined whether information other than identification information is written in the IC tag 20G. Specifically, when the article information read in S1010 includes entrance date information and entrance machine information written in S1020, which will be described later, information is written, that is, an IC tag that has already undergone entrance processing. It is determined that it is a unit 510, and it is determined whether or not re-entry is possible in S1014.

  In S1014, it is checked whether it is a period during which re-entry is possible or whether information that can be re-entry is input. Specifically, the server 530 uses the identification number acquired in S1010 as the identification number permitted to enter, whether it is within a re-entryable period, whether the previous entry was made through a regular entrance machine, or not. It is checked whether it is stored in If re-entry is possible, the IC tag unit is transported to the ticket outlet at S1016, and this process is terminated. On the other hand, if re-entry is not possible, the process proceeds to S1080.

  If information other than the identification information is not written in S1012, as S1020, the reader / writer device 521 is sent a write command, and the IC tag 20G identifies the entry date / time information as the article information and the entry machine. Write admission information.

  Subsequently, in S1030, it is determined whether or not the writing in S1020 is completed. If writing is not possible, the process proceeds to S1080, assuming that there is a possibility that the stub has been cut in advance or that it is an illegal admission ticket.

  On the other hand, if the writing has been completed, the stub (second piece 512) is cut off by the admission ticket processing device 522 in S1040. As a result, the state detection wiring 26G is disconnected, and writing of data (article information or the like) to the storage unit becomes impossible due to the hardware configuration.

  Thereafter, in S1050, it is determined whether or not writing is impossible. Specifically, the reader / writer device 521 is inquired as to whether or not a write prohibition flag is set in the IC tag 20G, and if the flag is set, it is determined that writing is impossible.

  If the write prohibition flag is set, it indicates that the state detection wiring 26G is disconnected and writing of data (article information, etc.) to the storage unit is impossible due to hardware configuration. If not, it indicates that data can be written to the storage unit in terms of hardware configuration. Further, in the state where the write prohibition flag is set, not only writing of article information but also writing of control software and application software is prohibited.

If writing is not possible in S1050, the process proceeds to S1080, assuming that there is a possibility that an error has occurred when the stub is cut out or that the ticket is illegal.
If writing is impossible, the first piece 511 of the IC tag unit 510 is sent to the ticket opening 525 as S1060, and then the identification information, admission date / time information, and admission machine information acquired at S1010 are sent to the server 530 as S1070. Send to. The server 530 stores such information in the admission management database. Thereafter, this process is terminated.

If re-entry is not possible in S1014, if writing cannot be completed in S1030, and if writing is not impossible in S1050, the IC tag unit 510 is returned to the ticket entrance in S1080, and then S1090. As a result, an abnormal admission ticket is output to an external device (such as an administrator call speaker), and the process is terminated.
<Processing by IC tag>
The processing procedure of the IC tag control process executed by the IC tag 20G will be described with reference to FIG.

The processing unit of the IC tag 20G first determines whether or not the write prohibition flag has been set (S610).
As a result of the determination in S610, if the write prohibition flag has not been set, the process proceeds to S620, and it is determined whether or not the state change work has been completed. The state change work in the present embodiment is a work for cutting out the stub (second piece 512) by the admission ticket processing device 522.

  In S620, if the state detection wiring 26G can be energized, it is determined that the above operation is not performed, and if the state detection wiring 26G is not energizable, it is determined that the above operation has already been performed.

If the result of determination in S620 is that state change work has been completed, a write prohibition flag is set (S630), and then processing proceeds to S640.
That is, when the operation command from the reader / writer device 521 is first received after the state detection wiring 26G is disconnected, the write prohibition flag is set.

  As a result of the determination in S610, if the write prohibition flag has been set, the process proceeds to S640. If the result of determination in S620 is that state change work has not yet been performed, the process proceeds to S640 while the write prohibition flag is not set.

  In subsequent S640, it is determined whether or not the received operation command is a write command from the reader / writer device 521. If the operation command is a write command as a result of the determination, it is determined in S650 whether or not the write prohibition flag has been set.

  If it is determined in S650 that the write prohibition flag has not been set, the article information transmitted from the reader / writer device 521 is written in the storage unit (S660), and the process is terminated. Then, it waits until the next operation command is input.

  On the other hand, as a result of the determination in S650, if the write prohibition flag has been set, the article information transmitted from the reader / writer device 521 is discarded, and this process is terminated. After that, it waits until the next operation command is input.

By the way, as a result of the determination in S640, if the received operation command is not a write command, the process proceeds to S670.
In S670, it is determined whether or not the read command is from the reader / writer device 521. If the result of this determination is that the operation command is a read command, the article information stored in the storage unit is read in S680. Then, the article information read from the storage unit is output to the transmission / reception unit. Then, the transmission / reception unit transmits the article information read from the storage unit to the reader / writer device 521. Thereafter, this process is terminated, and the process waits until the next operation command is input.

On the other hand, if the result of determination in S670 is that the operation command is something other than a write command or a read command (for example, a check command for testing the operation of the IC tag 20G), the process proceeds to S690. In S690, control according to the operation command (for example, if it is a check command, a check operation for checking whether the IC tag 20G operates normally) is executed. Thereafter, this process is terminated, and the process waits until the next operation command is input.
<Processing by reader / writer device>
The processing procedure of the read processing executed by the reader / writer device 521 will be described based on the flowchart shown in FIG.

When this read process is started, as shown in FIG. 21, a read command is transmitted to the IC tag 20G via the transmission / reception antenna 521A in S540.
In subsequent S550, it is determined whether or not the article information returned from IC tag 20G has been acquired via transmission / reception antenna 521A. If the article information is not acquired as a result of the judgment, it is judged that the IC tag 20G does not exist within the communication range of the reader / writer device 521, or the article information is not returned even if it exists. , The process returns to S540, and the read command is transmitted again.

On the other hand, if the article information is acquired, that is, if the IC tag 20G exists within the communication range of the reader / writer device 521 and the IC tag 20G returns the article information, the process proceeds to S560. In S560, the article information transmitted from the IC tag 20G is output to the control device 523. Thereafter, the read process is terminated.
[Effect of the seventh embodiment]
As described above, in the admission system 501 of the present embodiment, the IC tag 20G of the IC tag unit 510 is writable at the time of admission, or data that can be re-entered is stored, or the admission date / time data is stored. Admission is not allowed unless it matches. Further, only the stub (first piece 511) returns to the entrant at the time of entrance, and the IC tag 20G of the stub is in a state where writing is impossible. Therefore, it is very difficult to reproduce or make the IC tag unit 510 usable based on the first piece 511, so that it is possible to suppress the creation of a counterfeit admission ticket. .

  Further, since the IC tag 20G remains on the first piece 511, the IC tag 20G can be used for reception of an event or reservation in the facility. Further, by comparing the article information read from the IC tag 20G at the time of the reception or reservation with the article information stored in the server 530, for example, to prevent unauthorized use of a stub that has already expired. Can do.

Furthermore, when it is desired to enter without using the entrance machine 520, for example, when the number of visitors to the facility is large and the entrance is congested or when the entrance machine 520 breaks down, the IC tag unit 510 of this embodiment is used. Then, it is possible to prevent writing to the IC tag 20G only by manually cutting off the second piece 512. As a result, the congestion of the entrance can be eliminated, and it is possible to make it difficult to use the IC tag 20G for forgery of the entrance ticket, or to make the re-entry impossible because it has been used.
[Modification of the seventh embodiment]
The seventh embodiment of the present invention has been described above, but the present invention is not limited to the above embodiment, and can be implemented in various modes without departing from the gist of the present invention. .

  For example, in the above-described embodiment, the system for managing entrance is illustrated, but a boarding ticket or a ticket that can be used for a predetermined period can be used.
