Abstract

PURPOSE:To prevent the generation of mistake at the time of issue and the lowering of the working efficiency by providing an electronic tag, which can be issued in any stage of a delivery system. CONSTITUTION:When a punch hole 36 is punched out to cut an operation starting line 34, a transistor Tr of a starting circuit 31g is electrified, and a response circuit 3 starts the operation. At this stage, when the reset signal is input from a reset circuit 31i to a CPU 31d, the CPU 31d carries out the initialization program firstly to clear the whole of a memory 31c and set it at the initial value. Thereafter, the issue processing is performed, but the data of the memory 31c becomes the data corresponding to the information written by the issue processing, and on the other hand, the data of a memory, which is started but not yet issued, is left at the initial value. Consequently, even in the case where the both data exist in a delivery system, a delivery slip, which is already issued, and a delivery slip, which is not yet issued, can be discriminated by judging that the read-out data is a data at the initial value or not.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic tag, for example, it is provided with a response circuit for storing information on delivery and transmitting the stored delivery information in response to an inquiry signal from an interrogator. It is used for electronic tags.

[0002]

2. Description of the Related Art Conventionally, as an electronic tag used in a delivery system such as a courier service, it is provided with a response circuit for storing information regarding delivery and transmitting the stored delivery information in response to an inquiry signal from an interrogator. Things are known. It is necessary to write (issue) an identification code in this electronic tag when it is first activated. Otherwise, different electronic tags will be confused because the packages attached with them will be recognized as the same.

In general, it cannot be visually judged whether the electronic tag has been issued or not, and it cannot be visually judged. Therefore, if both issued and unissued items are mixed, it is not possible to know which ones have been issued or which have not yet been issued and need to be issued. In order not to cause the inconvenience, it is necessary to perform the issuing work only at a certain fixed stage in the delivery system.

For example, in a package delivery system using an electronic tag, if the issuing work is limited to a certain stage as described above, the following two are conceivable.
Is one of the two. (A) Issued just before the electronic tag is attached to the package.

(B) After the electronic tag is attached to the package, it is issued before the automatic sorting.

[0006]

However, if it is limited to the above (a), since the package until the electronic tag is attached cannot be distinguished, another memo containing information such as the addressee is written. It is troublesome to have to put it on. Also, when attaching the electronic tag to the luggage, it is necessary to confirm the correspondence between the issued electronic tag and the luggage to which it is attached, and there is a possibility that the mistake may be inadvertently stuck to the wrong luggage. There is a nature.

On the other hand, if it is limited to (b), after a lot of parcels are collected, a troublesome issuing process must be performed for all parcels, so that work efficiency for other processes is improved. Even if it is done, the efficiency of the entire delivery system is deteriorated due to the delay in the work at the issue processing stage.

Therefore, the present invention has been made in view of the above problems. By providing an electronic tag that can be issued at any stage of the delivery system, mistakes at the time of issuing and a reduction in work efficiency can be achieved. The purpose is to prevent.

[0009]

According to another aspect of the present invention, there is provided an electronic tag having a battery for supplying power, the delivery being stored in advance in a rewritable internal storage means. In an electronic tag having a response circuit for transmitting information in response to an inquiry radio wave from an interrogator, the response circuit includes a switching means for switching a power supply state from the battery to an energized state and a substantially cutoff state. And a reset unit for resetting the data in the internal storage unit to a predetermined initial value when power is supplied from the battery by the operation of the switching unit.

Further, the electronic tag according to the present invention has a battery for supplying power, and transmits the information regarding the delivery stored in advance in the rewritable internal storage means in response to the inquiry radio wave from the interrogator. In an electronic tag having a response circuit having a transmission means, the response circuit has switching means for switching a power supply state from the battery to an energized state and a substantially cutoff state, and the delivery information stored in the internal storage means. Is read out and transmitted to the transmitting means, or the internal storage means is masked to switch whether to transmit a predetermined initial value instead of the delivery information, and an operation of the switching means to supply power from the battery. When receiving the supply,
The information masking means is reset so that the delivery information is masked, and the information masking means is controlled in association with the writing to the internal storage means, and the delivery information stored in the internal storage means is controlled. And an information control means for transmitting the information to the transmitting means.

The response circuit further includes a circuit test terminal, and by supplying power or forcibly operating the switching means through the circuit test terminal, the response circuit is forced to operate even when the switching means is inactive. By operating the circuit test terminal after starting the operation of the response circuit, while making it possible to reset the data in the internal storage means to a predetermined initial value by the reset means, The initialization function of the reset means may be operable again.

Further, the internal storage means may be a write-once type, and in addition, at least storage control means for making it impossible to erase the data written at the time of issuing may be provided.

[0013]

According to the electronic tag according to the first aspect of the present invention, the switching means in the response circuit operates to switch the power supply state from the battery to the energized state to activate the electronic tag. The reset means resets the data in the internal storage means to a predetermined initial value when the power is supplied from the battery by the operation of the switching means.

After that, the data of the internal storage means in the electronic tag after the issuing process becomes according to the information written in the issuing process. On the other hand, the data of the internal storage means in the electronic tag that has been activated but has not been issued retains the initial value. Therefore, even if both are mixed in the delivery system, it is possible to determine whether the electronic tag has been issued or has not been issued by determining whether the data in the internal storage means is the initial value. . Then, for example, the unissued one can be dealt with by issuing at that time based on the data handwritten on the electronic tag.

As described above, even when the issued and unissued electronic tags are mixed in the delivery system, they can be distinguished from each other. Therefore, the electronic tags are issued at any stage of the delivery system. Get better. In addition, claim 2
According to the electronic tag described, when the power is supplied from the battery by the operation of the switching means in the response circuit, the reset means resets the information masking means to mask the delivery information and replaces the delivery information with a predetermined initial value. To convey. On the other hand, the information control means controls the information mask means in conjunction with the writing to the internal storage means so that the delivery information stored in the internal storage means is read and transmitted to the transmission means.

Therefore, as in the case of claim 1, even if the electronic tag that has been issued and the electronic tag that has not been issued are mixed in the delivery system, they can be distinguished, and the electronic tag of claim 2 can be distinguished. According to this, it is not necessary to initialize all the data in the storage means as the processing after reset, and it is possible to save the processing time and power consumption for writing especially when the storage capacity is large. .

[0017]

Embodiments of the present invention will be described below with reference to the drawings. In this embodiment, a case where the present invention is applied to an electronic tag in a delivery system of a courier and its operation system will be described.

In FIG. 1, an information storage medium (electronic tag)
The courier delivery slip 1 is composed of a plurality of various slips, and the conventional delivery slip function and electronic tag function are contained in one slip. This courier slip 1 is mainly composed of a handwritten entry field 2, a response circuit 3, and a code display unit 4. The handwritten entry field 2 is a portion where the customer (client) manually writes information such as the delivery destination and the shipping origin, and the arrival code (sorting code) and charges are handwritten at the courier agency. is there.

The response circuit 3 has, as a basic configuration, an antenna 32 for exchanging data, an IC 31 for controlling the circuit and storing delivery data, and a battery 33 for supplying electric power to the IC 31. The data is input to the IC 31 by a non-contact communication method using radio waves, for example, using an issuing machine described later.

The stored data is composed of fixed data and variable data, and the fixed data includes a slip number (that is, a symbol indicating a package identification code) written on the slip.
However, as the variable data, the sorting code, the telephone number, etc. are input when the package is handled. The code display unit 4 is for optically or magnetically reading the slip number, and is composed of one or a combination of two or three well-known OCR characters 41, MICR characters 42, and bar codes 43. The numbers, codes, etc. corresponding to the slip numbers are pre-filled when the slips are manufactured.

Next, the structure of the response circuit 3 built in the home delivery slip 1 will be described. FIG. 2 is a circuit configuration diagram showing a specific configuration of the response circuit 3. In FIG. 2, a response circuit 3 includes an IC chip 31 that performs internal signal processing, an antenna 32 that receives an inquiry radio wave S1 and transmits a response radio wave S2, a built-in battery 33 that drives the IC chip 31, and a response before starting use. An operation start line 34 for stopping the operation of the circuit 3 and an operation end line 35 for ending the operation of the response circuit 3 when the circuit 3 is used.

A punch hole 36 is formed on the operation starting line 34.
And a cutoff line 37 is provided on the operation end line 35. The substrate material of the response circuit 3 is, for example, a material such as polyester, polyimide, or paper, and the punch holes 36 configured in the response circuit 3 are used in a punching machine configured in an issuing machine described later or a manual punching machine. It is formed so that it can be easily punched.

Further, the IC chip 31 has a detector 3 for extracting the information contained in the interrogation radio wave S1 received by the antenna 32.
1a, a level comparator 31b that determines reception of an inquiry radio wave based on the signal level from the detector 31a and starts signal processing, a memory 31c that stores baggage information and the like, and a level comparator 31b to supply power. Memory 3 when received
A central processing unit (hereinafter referred to as CPU) 31d that performs a transmission operation based on the package information stored in 1c, and a CPU 31
A clock generator 31e for generating a clock signal for operating d, a modulator 31f for modulating the interrogation radio wave S1 based on an output signal from the CPU 31d and transmitting a response radio wave S2 from an antenna 32, and a starter corresponding to a switching means. When the circuit 31g, the discharge circuit 31h, and the operation start line 34 are disconnected and the response circuit 3 starts the operation, the CPU 31
a reset circuit 31i for outputting a reset signal to d
It is composed of a circuit test terminal 31j for confirming the operation of C. Of these, the starting circuit 31g mainly includes a transistor Tr and an inverter INV.

Next, the operation of the home delivery slip 1 constructed as described above will be described with reference to the flowchart of FIG. In FIG. 2, before using the response circuit 3,
That is, since the operation start line 34 is connected when the courier slip is in the storage state, the inverter I
The input to NV becomes low level, and the transistor Tr is in a cutoff state.

When the response circuit 3 is used, first, the punch holes 36 of the response circuit 3 are punched by a punching device or a manual punching device which is configured in the issuing machine described later. Then, the operation start line 34 is disconnected, so that the inverter IN
The input to V becomes high level, the transistor Tr becomes conductive (step 11), and the response circuit 3 starts its operation (step 13). At this time, the reset signal output from the reset circuit 31i is
When input to d (step 15), the CPU 31d first executes the initialization program, clears the entire memory 31c to the initial value 0 (step 17), and waits for signal input (step 19).

Since the current consumption of the response circuit 3 before the punch holes 36 are punched out is about 0.1 μA, even if the courier slip 1 is stored for one year, for example.
It consumes only 0.9 mAh of battery capacity in one year, and has a circuit configuration that minimizes battery consumption during storage.

After the response circuit 3 is operated, when the package information is written in the response circuit 3 by the issuing machine, which will be described later, the question signal S1 from the issuing machine (the writing command and the package information are loaded in the question signal at this time). Is received by the antenna 32, and the level comparator 31b receives the received signal from the level comparator 31b.
Power supply to 1d and the clock generator 31e is started. Then, the CPU 31d determines the writing of the package information by receiving the write command, and if it is a write signal (step 19: YES), the package information is stored in the memory 31c.
Write to (step 21).

The memory 31c is operable immediately before the writing operation and is backed up by the battery to store and hold the baggage information. If the signal received at this time is a read signal (step 23: YES), the memory 31
The content of c (initial value data in this case) is transmitted (step 25), and the process returns to step 19.

When the antenna 32 receives the interrogation radio wave S1 again after the package information is written in the memory 31c, the level comparator 31b causes the CPU 3 to receive the interrogation radio wave S1.
Power supply to 1d and the clock generator 31e is started. Then, the CPU 31d modulates the inquiry radio wave 31 with the package information stored in the memory 31c, and causes the antenna 32 to transmit the response radio wave S2 having the package information. At this time, in order to reduce information transmission errors, the response radio wave S2 should preferably use two stages for 1-bit transmission such as Manchester or F2F code.

When the use of the courier slip 1 is finished, radio wave interference and malfunction (for example, when trying to use the box to which the used courier slip 1 is pasted again,
In addition to the new parcel delivery slip 1 during automatic sorting, response radio waves are also transmitted from the used courier delivery slip 1 and a malfunction occurs during automatic sorting).
7 is cut off and the operation end line 35 of the response circuit 3 is cut off. Then, the discharge circuit 31h is activated to discharge the electric power remaining in the built-in battery 33, and the courier slip 1 becomes unusable.

Further, in the response circuit 3 before the operation start line 34 is disconnected (before the operation is started, that is, when the courier slip 1 is in the storage state), for example, an operation check of the response circuit 3 is performed as an inspection after manufacturing. Circuit test terminal 31j
The initialization program is executed by supplying the driving power of the response circuit 3 from the memory 31c to the initial value 0.
Can be cleared.

As described above, the response circuit 3 is activated at the time of activation using the circuit test terminal 31j in the same manner as when the operation start line 34 is disconnected, and communication is possible. When the operation check is completed, the circuit test terminal 31
Connect j once to ground (set voltage to 0 volts)
Then, the electric charge of the capacitor of the internal reset circuit 31i is discharged and the operation is cleared. Even when the operation start line 34 is cut to actually operate the response circuit 3, the reset circuit 31i operates correctly and C
The memory 31c is surely initialized by the PU 31d.

By utilizing this circuit test terminal 31j, it is possible to rewrite the data of the response circuit 3 (for example, when wrong data is written when the response circuit 3 is issued). That is, if the circuit test terminal 31j is short-circuited to the ground for a short time, the response circuit 3 is activated again, the memory 31c is initialized, and the memory 31c can be operated from the beginning and can be issued again.

Next, the detailed structure of the above-mentioned issuing machine will be described. FIG. 4 is a schematic configuration diagram showing the configuration of the issuing machine of the home delivery slip 1. In FIG. 4, the issuing machine 5 includes a set slit 57 for inserting the courier slip 1, a punching device 51 for punching the punch holes 36 of the response circuit 3 provided in the courier slip 1, and a courier slip 1 on the courier slip 1. A bar code reader 52 for reading a bar code 43 corresponding to a slip number, which has been entered in advance, a keyboard 53 for inputting package information, a writer 54 for writing necessary information in the response circuit 3, and a display for displaying the written information. 55, a computer 56 that controls each part while performing information processing, and a printer 58 that prints necessary information at a predetermined position on the home delivery slip 1.
It is composed of and.

When a series of data input is completed,
The courier slip 1 is attached to the parcel requested by the client, the slip of the slip is given to the client, and the necessary slips are extracted and stored at the courier agency. In this case, the courier service may store the data at the time of issuance in the internal or external memory of the issuing machine 5, instead of storing the slip pieces. Further, by connecting the issuing machine 5 to a computer of a delivery center (H in FIG. 7) online, input data can be immediately transmitted to the delivery center H, and home delivery information can be managed year-round.

Next, the detailed structure of the writer 54 constituting the issuing machine 5 will be described. FIG. 5 is a circuit configuration diagram showing a specific configuration of the writer 54. In FIG. 5, the writer 54 includes a CPU 54a that controls each unit, a carrier oscillation circuit 54c that oscillates a carrier wave, and a modulation circuit 54b that modulates the carrier wave of the carrier oscillation circuit 54c.
An antenna 54e that transmits the inquiry radio wave S1 and receives the response radio wave S2, a circulator 54d that separates the inquiry radio wave S1 and the response radio wave S2, and a demodulation circuit 54f that demodulates the data contained in the received response signal S2. It is composed of and.

The operation of the writer 54 having the above-described configuration will be described. The CPU 54a, which receives the package information output from the computer 56, according to the package information, modulates the carrier wave from the carrier oscillation circuit 54c with the modulation circuit 54b. Modulation by. This modulated signal is transmitted from the antenna 54e as an inquiry radio wave S1 (writing radio wave) to the response circuit 3 of the courier slip 1 via the circulator 54d, and the response circuit 3 receives the inquiry radio wave S1 and receives the package information. Is stored in the memory 31c, and after the storage operation is completed, a confirmation signal for confirming the stored content (response radio wave
2) is transmitted to the writer 54.

The confirmation signal transmitted from the response circuit 3 is demodulated by the demodulator 54f via the antenna 54e and the circulator 54d and output to the CPU 54a. C
The PU 54a detects the demodulated confirmation signal, outputs the detection result to the computer 56, and outputs the response circuit 3
The write operation for is ended.

A system for issuing and operating the home delivery slip 1 configured as described above will be described with reference to FIGS. 6 and 7. In FIG. 6, the situation from the start of the courier slip 1 to the stage of pasting on the parcel will be described, and in FIG. 7, the system for processing the parcel with the parcel slip 1 attached in FIG. 6 at the distribution center will be described.

As shown in FIG. 5, the courier slip 1 cut from the bundle 6 of slips is divided into (a) side or (b) side in FIG. 6 depending on whether the issuing machine 5 is used or not. The example (a) in the upper part is a case where the issuing machine 5 can be used, for example, a situation where a parcel is brought into an agency store. Here, first, the sender fills in the handwritten entry field 2 of the courier slip 1a with the necessary items such as the delivery address of the parcel and the telephone number, and then the issuing machine 5 activates the parcel delivery slip 1a, writes the parcel information, prints, etc. Then, the courier slip 1 is attached to the parcel 14a requested for delivery.
In this case, the courier slip 1a attached to the luggage 14a
Has been issued.

On the other hand, the lower example (b) is a case where the issuing machine 5 can be used, for example, a situation where a truck or the like goes around the sender and collects cargo. Here, as in the case of the example (a) in the upper part, handwriting is performed on the home delivery slip 1b. Then, punch holes 36 with a manual punch.
b is emptied, the courier slip 1b is activated, and the package 14b
Pasted on. In this case, the courier slip 1b attached to the package 14b is in an unissued state although it is activated. In this description, when the courier slip is simply indicated as 1, it is assumed that there is no distinction between issued and unissued.

Next, a system for processing the parcels 14a and 14b passing through the route shown in FIG. 6A or 6B will be described with reference to FIG. The parcels 14a and 14b to which the above-mentioned home delivery slips 1a and 1b are pasted are carried to a delivery center H by a delivery company and processed. That is, in the distribution center H, the package 14 including the packages 14a and 14b is mixed.
(If it is simply indicated as 14, there is no distinction between the two.) Is placed on the belt conveyor 40a, and an interrogator 30a provided near the belt conveyor 40a transmits an interrogation signal so that the parcel delivery service is attached to the parcel 14. The built-in information of slip 1 is returned and the signal is output to the computer 45a.

The computer 45a determines whether the read information is the initial value and determines whether the courier slip 1 has not been issued. If it is determined that the baggage has not been issued, the relevant package is sent to the belt conveyor 40b by the automatic sorter 47a. Then, the worker refers to the data described in the courier slip 1 and refers to the interrogator (writer) 30b and the computer 45b provided near the belt conveyor 40b.
The parcel delivery slip 1b is issued according to the above, and the parcel 14b for which the issuance is completed is merged with the parcel on the belt conveyor 40a and placed on the belt conveyor 40c, and is automatically sorted according to the destination of the parcel.

That is, after that, the baggage 14 is placed on the belt conveyor 40c, and an inquiry signal is transmitted from the interrogator 30c provided in the vicinity of the belt conveyor 40c (the basic configuration is the same as that of the writing device 5 described above). Then, the built-in information of the home delivery slip 1 attached to the package 14 is returned and the signal is output to the computer 45c.

The computer 45c controls the operation of the automatic sorter 47c based on the read package information,
The parcel 14 is distinguished for each destination area. The distinguished packages 14 are sent to the delivery bases of the respective districts, and from there to the destinations. It should be noted that although the necessary slip pieces are cut off during the delivery process of the package 14, the bar code 43 is attached to each slip piece.
Etc., the bar code 43 and the like can be used to perform the voucher processing that is normally performed.
Further, instead of cutting out the slip pieces, it is also possible to read the package information with an interrogator (the same configuration as the interrogator 30) and apply it to slip processing.

As described above, the courier slip 1 in this embodiment has been issued, but the data in the memory 31c corresponds to the information written in the issuance process, while it has been activated. The data in the memory 31c that has not been issued remains at the initial value 0. Therefore, even if they are mixed in the delivery system, the memory 31c
It is possible to determine whether the issued courier slip 1 or the unissued courier slip 1 is determined by determining whether or not the data of 1 is the initial value 0. And for unissued ones,
Based on the data handwritten on the courier slip 1,
It can be dealt with by issuing at that point.

In this way, even if the issued and unissued courier slips 1a and 1b are mixed in the delivery system, it is possible to distinguish between them. It can be performed on the stage, and it is possible to prevent mistakes at the time of issuance and reduction in work efficiency.

Next, another embodiment will be described. In the structure shown in FIG. 8, the operation start line 34 is formed in the connecting portion 62 of the slip bundle 6 of the home delivery slip 1 and is connected to the response circuit 3 across the perforations 61. As a result, the courier slip 1 is automatically activated when the courier slip 1 is cut out from the bundle of documents 6. Therefore, even when the issuing machine 5 as shown in FIG. 6B is not used, it is not necessary to purposely punch the punch hole 36b, and it is possible to prevent the mistake of forgetting to punch the punch hole 36b from occurring.

Further, the one shown in FIG. 9 is configured such that the memory 31c of the response circuit 3 is divided into a plurality of blocks for management. For example, the identification information, the parcel-specific information, and the like are written at the time of issuance, and the free space thereafter is managed as an additional recording area. Then, when data is newly written to the response circuit 3, it is processed by writing in the additional recording area, and the already written information at the time of issuing cannot be rewritten.

By doing so, the memory 31 for identifying information and the like is provided.
It is possible to almost eliminate the risk that the heavy information in c is inadvertently rewritten. Also, the CPU 3 of the response circuit 3
If the additional write data cannot be erased as the control of 1d, when the response circuit 3 is used for a purpose such as a coupon ticket,
Writing the usage history as additional recording data makes it impossible to erase the usage history. Therefore, since the usage history can be confirmed, it can be expected to be very effective in terms of fraud prevention.

In order to manage the use status of such an additional write area, generally, an area for storing management information is provided as shown in FIG. 9A, and the management information should be checked and written when rewriting the additional write data. It is necessary to calculate the write-once area, write it in that area, and update the stored management information. However, as described above, if all the contents of the memory 31c are set to the initial values when the response circuit 3 is activated, the unused additional write area always becomes the initial value.
By sequentially accessing the additional write area, the area to be written can be determined, and no special management information area is required as shown in FIG. 9B. Therefore, there is a secondary effect that the memory usage efficiency is good and the control of the internal processing circuit is simple.

As yet another embodiment, an example regarding reset will be described with reference to FIG. 10 showing an operation flow of the response circuit 3. When the punched holes 36 are punched out, the power is turned on (step 101) and the response circuit 3 starts its operation (step 103). At this time, when the reset signal output from the reset circuit 31i is input to the CPU 31d (step 105), the CPU 31d first turns on the mask flag to execute the initialization program (step 107) and waits for the input of the signal ( Step 10
9).

When a signal is thus input, it is decoded (step 111). If there is an error, the process returns to signal waiting, and if it is a write signal, the process proceeds to step 113, and if it is a read signal, the process proceeds to step 122. When the input signal is the write signal, the package information which is the data in the write signal is written in the memory 31c (step 113). Then, in conjunction with the write signal, the mask flag is turned off (step 115).

On the other hand, when the input signal is the read signal, the mask flag is checked (step 121), and when it is on, the initial value data is transmitted to the transmitting means to transmit the initial value data (step 123). When the mask flag is off, the memory data is read and transmitted to the transmitting means to transmit the memory data (step 125).

In this way, it is not necessary to set all the data in the memory 31c to the initial values as the processing after the reset, and especially when the memory capacity is large, the processing time and power consumption for the memory writing are saved. It is also possible to do so. In the above-described embodiment, the information mask means of the internal storage means of the present invention and the information control means for controlling the information mask means are both realized by the software of the CPU 31d.

Next, the circuit test terminal 31j shown in FIG.
11 shows another example of the configuration. The circuit test terminal 31j 'in FIG. 11 operates to control the starting circuit 31g. Also in this case, regardless of the state of the operation start line 34,
It can be used to forcefully drive the circuit or as a reset after startup.

That is, when confirming the operation of the response circuit 3 before the operation start line 34 is cut, for example as a post-manufacturing inspection, the circuit test terminal 31j 'is set to the high level state. The starting circuit 31g operates,
The circuit driving power is supplied from the built-in battery 33, and the CPU 31
d executes the initialization program. In this way, the response circuit 3 starts the operation at the time of starting using the circuit test terminal 31j ', and becomes capable of communication just as when the operation start line 34 is disconnected.

Further, it can be used when the response circuit 3 wants to rewrite data after the operation is started. That is, if the circuit test terminal 31j ′ is short-circuited to the ground, the response circuit 3 is stored again, and then the circuit test terminal 31j ′ is
If j'is released, the system is activated again and can be operated from the beginning. Therefore, according to this example, when the operation of the response circuit 3 is checked, the built-in battery 33 can also be checked.

As described above, according to the electronic tag of the present invention, it is possible to distinguish between issued and unissued electronic tag in the delivery system. Issuing may be performed at the stage, and there is an excellent effect that it is possible to prevent mistakes at the time of issuance and reduction in work efficiency.
