<2. Table data>
The hard disk 14 of the host computer 1 mainly stores three table data: a work table T1, a correspondence table T2, and a history table T3. Each will be described below.

  First, the work table T1 will be described. The work table T1 mainly indicates sorting information indicating how many products should be sorted in each merchandise shelf 5, and sorting work is performed based on the registered contents of the work table T1. The work table T1 is created based on orders received from each store before sorting work.

  FIG. 9 is a diagram illustrating an example of the work table T1. As shown in the figure, the work table T1 is data in a table format composed of a plurality of records R1. One record R1 corresponds to one store and indicates the number of products ordered from the store. That is, one record R1 indicates a necessary work amount (the number of products to be input) with respect to one product shelf 5.

  Each record R1 is composed of shelf data Da relating to the product shelf 5 itself and product data Db regarding the product to be put into the product shelf 5. The shelf data Da includes “product shelf code”, “store name”, and “store code”. “Store name” is the name of the store that is the delivery destination, and “Store code” is an identification code for identifying the store.

  In the product data Db, information related to one type of product is registered as one sub-record R2. Each of the sub-records R2 includes “product code”, “product name”, “sort quantity”, and “container number”. The “product code” is an identification code for identifying the product, the “product name” is the name of the product, and the “sort quantity” is the number to which the product is to be input. The “container number” is information indicating in what order the product is placed in the container 6 placed in the sorting operation. This “container number” is blank before the sorting operation, and the contents are sequentially registered during the sorting operation.

  Next, the correspondence table T2 will be described. The correspondence table T2 is correspondence information for associating the product shelf 5 and the electronic tag 3 that physically correspond to each other in data. More specifically, the correspondence table T2 associates the product shelf 5 with the electronic tag 3 attached to the container 6 disposed on the product shelf 5 in terms of data.

  FIG. 10 is a diagram illustrating an example of the correspondence table T2. As shown in the figure, the correspondence table T2 is data in a table format composed of a plurality of records Re. In each record Re, “product shelf code” and “device code” are registered in association with each other. Thereby, the product shelf 5 and the electronic tag 3 are associated in terms of data.

  As described above, in the sorting operation, when the container 6 is full, the container 6 placed on the commodity shelf 5 is changed. Therefore, the electronic tag 3 corresponding to one merchandise shelf 5 is also changed with the change of the container. The contents of the correspondence table T2 are updated every time the electronic tag 3 is changed during the sorting operation, and the electronic data related to the container 6 (the container 6 placed last) placed on the commodity shelf 5 at that time. The information of the tag 3 is shown.

  Next, the history table T3 will be described. The history table T3 is history information indicating all histories of the electronic tag 3 that are changed during the sorting operation. FIG. 11 is a diagram illustrating an example of the history table T3. As shown in the figure, the history table T3 is tabular data composed of a plurality of records Re1.

  Each record Re1 corresponds to one product shelf 5, and one “product shelf code” is registered. In each record Re1, “device codes” relating to all the electronic tags 3 associated with the product shelf 5 are registered as sub-records Re2. The sub-record Re2 includes “usage order” and “device code”. The “use order” indicates the order in which the electronic shelf 3 related to the product shelf 5 is used, that is, the order of association. This history table T3 is also updated every time the electronic tag 3 is changed during the sorting operation.

<3. Sorting work>
Next, sorting work using the sorting system 10a will be described. In the following, in order to simplify the description, attention is focused on a certain product shelf 5, and the flow of operations and processes mainly related to the product shelf 5 that has focused on will be described. Hereinafter, the product shelf 5 of interest is referred to as a “product shelf of interest” and is distinguished from other product shelves 5. FIG. 12 is a diagram illustrating a flow of work and processing related to the product shelf of interest. Actually, operations and processes similar to those in FIG. 12 are performed in parallel for all the product shelves 5.

  First, as an initialization process of the host computer 1, the “order variable” that is a variable handled by the CPU 11 is set to “1”. The “order variable” indicates the use order of the order in which the container 6 placed on the product shelf of interest is used at that time. In other words, the “order variable” also indicates the use order of the electronic bills 3 associated with the product shelf of interest. The CPU 11 of the host computer 1 manages the “order variable” for each of the plurality of product shelves 5 (step S1).

  Next, an empty container 6 is placed on the noticeable commodity shelf by the worker P. At this time, an unused electronic tag 3 that is not associated with any product shelf 5 is attached to the container 6 (step S2).

  The electronic tag 3 needs to be associated with the product shelf of interest in terms of data. For this reason, when the container 6 is placed on the noticeable merchandise shelf, next, the associating process for associating the noticeable merchandise shelf with the electronic tag 3 is performed (step S3). For this association process, the handy terminal 4 carried by the worker P is used.

  FIG. 13 is a diagram showing the flow of the association process (step S3). In the figure, the left flow shows the operation of the handy terminal 4, and the right flow shows the operation of the host computer 1.

  First, the barcode of the label 25 affixed to the front of the number indicator 2 arranged on the noticeable product shelf is read by the barcode reader 42 of the handy terminal 4. Thereby, the product shelf code of the product shelf of interest is acquired by the handy terminal 4 and stored in the memory of the control unit 45 (step S21).

  Next, the barcode of the label 35 attached to the front surface of the electronic tag 3 attached to the container 6 placed on the noticeable product shelf is read by the barcode reader 42 of the handy terminal 4. Thereby, the device code of the electronic tag 3 is acquired by the handy terminal 4 and stored in the memory of the control unit 45 (step S22).

  Through these processes, both the product shelf code of the product shelf of interest to be associated and the device code of the electronic tag 3 are acquired by the handy terminal 4. Note that the order of steps S21 and S22 may be switched.

  Next, the acquired merchandise shelf code and the device code are transmitted from the communication unit 44 of the handy terminal 4 to the host computer 1 by unrelated communication using the third communication system 400 (step S23). The transmitted merchandise shelf code and device code are received by the host computer 1 via the wireless communication device 401 (step S31).

  In response to this reception, the CPU 11 of the host computer 1 generates one record Re of the correspondence table T2 so as to associate the received device code with the product code. As a result, the noticeable product shelf and the electronic tag 3 are associated in terms of data (step S32).

  Subsequently, the history table T3 is updated. That is, one sub-record Re2 is newly added for the record Re1 including the received device code in the history table T3. The “order variable” (that is, “1” at first) is registered in the “usage order” of the sub-record Re2, and the received device code is registered in the “device code” (step). S33). Thereby, the association process ends.

  Returning to FIG. 12, when the association process (step S <b> 3) is completed, the work table T <b> 1 is referred to, and “store name” and “store code” associated with the product shelf code of the product shelf of interest are CPU 11. Obtained by Subsequently, the correspondence table T <b> 2 is referred to, and the “device code” corresponding to the product shelf code of the product shelf of interest is acquired by the CPU 11. Then, the acquired “store name”, “store code”, and “order variable” at that time use the second communication system 300 for the electronic tag 3 of the “device code” from the host computer 1. Then sent.

  As a result, as shown in FIG. 14, on the electronic tag 3 of the container 6 placed on the noted product shelf, the “store name” 3a and the “store code” 3b of the store associated with the noted product shelf are displayed. . Furthermore, based on the transmitted “order variable”, the “usage order” 3c is also displayed on the electronic tag 3 (step S4).

  The worker P can confirm that the noticeable product shelf and the electronic tag 3 are associated in terms of data by such display of the electronic tag 3. Further, based on the “store name” and “store code” displayed on the electronic tag 3, it is possible to clearly grasp which store the container 6 corresponds to. Furthermore, the usage order of the containers 6 can be easily grasped from the “use order” displayed on the electronic tag 3.

  When the noticeable product shelf and the electronic tag 3 are associated with each other in terms of data, next, an actual sorting operation is performed. That is, first, the worker P transports one type of product to be sorted by the carriage 7 and causes the barcode reader Br of the operation terminal 201 to read the barcode indicating the product code attached to the product.

  The read product code is transmitted to the host computer 1. In response to this, the CPU 11 of the host computer 1 refers to the record R1 related to the product shelf of interest in the work table T1, and the “sort quantity” of the sub-record R2 corresponding to the product code indicates the number of products on the product shelf of interest. The data is transmitted to the device 2 using the first communication system 200. As a result, the “number of items to be sorted” is displayed on the number display 2 of the noticeable product shelf. At this time, the “order variable” at that time is registered in the “container number” of the sub-record R2 (step S5).

  Actually, the operation in step S5 is performed in parallel for all the product shelves 5 included in one zone Z. In other words, by reading the barcode of one type of product, the number of sorting is displayed on the number display 2 of all the product shelves 5 included in the same zone Z as the product shelf of interest.

  In accordance with the displayed “sorted quantity”, the worker P puts the number of products into the container 6 placed on the noticeable product shelf. When the insertion is completed, the completion button 22 of the number display 2 is pressed. As a result, the host computer 1 accepts that the insertion of the one type of merchandise related to the noticeable merchandise shelf is completed, and the display on the quantity display 2 of the noticeable merchandise shelf is turned off (step S6).

  Thereafter, the worker P repeats the operations in steps S5 and S6 for each type of product to be sorted. By repeating this process, the “order variable” at that time is sequentially registered in the “container number” of each sub-record R2 of the record R1 related to the product shelf of interest in the work table T1.

  Further, when the container 6 becomes full of commodities while repeating such work, the worker P needs to replace the container 6. At this time, the operator P depresses the full button 23 of the number display 2 before exchanging the container 6 (Yes in step S8). As a result, a predetermined signal is transmitted to the host computer 1 and the CPU 11 is notified that the container 6 is to be changed (that is, the electronic tag 3 is to be changed).

  In response to this, first, the CPU 11 refers to the record R1 related to the product shelf of interest in the work table T1, and among the sub-records R2, the “container number” stores the “order variable” at that time. The extracted contents (“product code”, “product name”, “sort quantity”, etc.) are acquired. The content of the acquired sub-record R2 indicates information on all the products that have been put into the container 6 before replacement. The contents of the sub-record R2 are transmitted from the host computer 1 to the electronic tag 3 associated with the noticeable product shelf in the correspondence table T2 at that time.

  As a result, as shown in FIG. 15, the information 3 d of all the products thrown into the container 6 is displayed on the electronic tag 3 associated with the container 6 placed on the product shelf of interest. In the example of the figure, “product name” and “sort quantity” for each product are displayed. The worker P can easily grasp the specific contents of the commodity accommodated in the container 6 by confirming such display of the electronic tag 3 (step S9).

  When the product information 3d is displayed on the electronic tag 3 in this way, the “order variable” is then incremented (+1) by the CPU 11 (step S9). This “order variable” is the use order of the container 6 placed next, and is also the use order of the next electronic tag 3. In this way, by incrementing the “order variable” in response to the change of the electronic tag 3, the use order of each electronic tag 3 associated with the product shelf of interest can be acquired.

  Thereafter, a new container 6 is placed on the noticeable product shelf (step S2). Then, in the same manner as described above, the new electronic tag 3 associated with the container 6 is associated with the noticeable product shelf, and the sub record Re2 related to the new electronic tag 3 is added to the history table T3 (step S3). ). As a result, the “store name”, “store code”, and “usage order” are also displayed on the new electronic tag 3 (step S4). For example, if the container 6 is used second, “2” is displayed as “usage order” on the electronic tag 3 attached to the container 6. Thereafter, in the same manner as described above, merchandise is input to the new container 6.

  Also, when the new container 6 is full of products, the full button 23 is pressed, and the operations of steps S9 and S10 are performed. That is, in the same manner as described above, information on all the products put in the container 6 is acquired, and the information is transmitted to the electronic tag 3 attached to the container 6 and displayed (step S9). As described above, the information on the product put into the container 6 is acquired based on the “order variable” described in the “container number” of the work table T1. The “order variable” is incremented every time it is accepted that the electronic tag 3 is changed (step S10). That is, the information on the product introduced between the two most recent changes of the electronic tag 3 is acquired as the product introduced into the container 6. In other words, based on the change of the electronic tag 3 and the work table T1, information on the product introduced for each container 6 is acquired.

  Such processing (steps S5, S6, S8 to S10) is performed until all types of products to be sorted are put into the product shelf of interest (during No in step S7). When all types of products have been charged, when the operator P presses the completion button 22, there is no sub-record R2 in which “container number” is blank in the record R1 related to the product shelf of interest in the work table T1. It is judged with.

  When the input for all types of products has been completed (Yes in step S7), first, in the same manner as in step S9, all the items that have been input to the container 6 placed on the product shelf of interest at that time are firstly displayed. The product information is acquired, and the information is transmitted to the electronic tag 3 attached to the container 6 and displayed (step S11).

  Next, the CPU 11 acquires the total number of all the electronic bills 3 (hereinafter referred to as “total number of uses”) associated with the product shelf of interest during the sorting operation. The total number of uses can be easily obtained based on the “order variable” at that time. Further, the number of sub-records Re2 included in the record Re1 related to the product shelf of interest in the history table T3 may be acquired as the total number of uses.

  Next, based on each sub-record Re2 of the record Re1 related to the product shelf of interest in the history table T3, “device codes” of all the electronic tags 3 associated with the product shelf of interest during the sorting operation are acquired. Then, the total number of uses is transmitted from the host computer 1 to all these electronic tags 3 using the acquired “device code”. As described above, since the electronic bill 3 can receive an infrared signal as long as it is in the work space, the total number of uses is also received in the electronic bill 3 attached to the container 6 dropped from the commodity shelf 5.

  Thereby, as shown in FIG. 16, the total usage 3e is displayed on all the electronic tags 3 associated with the product shelf of interest. The total number used is equivalent to the total number of containers 6 used for the product shelf of interest. That is, the worker P can easily grasp the total number of containers 6 to be delivered to the same store by confirming such display of the electronic tag 3 (step S12).

  Thus, the work and processing related to the product shelf of interest are completed, and thereafter, the container 6 in which the product is stored is delivered to the store related to the product shelf of interest. Since the electronic tag 3 attached to each container 6 is driven by the battery 34, the display of the electronic tag 3 as shown in FIG. 16 is maintained even during delivery by a truck or the like. For this reason, the worker in charge of delivery and the worker at the delivery destination store also visually recognize the display of the electronic tag 3, so that the store information 3 a and 3 b of the delivery destination of the container 6, It is possible to easily grasp the usage order 3c, the information 3d of the contents of the container 6, and the total number of containers 6 to be delivered to the store.

  As described above, in the sorting system 10a of the present embodiment, a plurality of product shelves 5 that are respectively associated with stores are provided, and containers 6 are placed on these product shelves 5. An electronic tag 3 is attached to each container 6 one by one, and the product shelf 5 and the electronic tag 3 attached to the container 6 arranged on the product shelf 5 are associated in terms of data by the correspondence table T2. Then, based on the correspondence relationship in the correspondence table T2, information on the store related to the product shelf 5 is displayed on the corresponding electronic tag 3. In this way, store information is attached to the container 6 based on accurate information in the correspondence table T2 instead of artificial information such as plates, so that correct information can be attached to the container 6. As a result, a situation where the container 6 is delivered to another store can be effectively prevented.

  Further, by using the handy terminal 4, a label 25 attached to the number display 2 of the product shelf 5 and a label 35 included in the electronic tag 3 of the container 6 actually placed on the product shelf 5, respectively. An identification code is acquired, and a record of the correspondence table T2 is generated based on these two identification codes. For this reason, the record of the correspondence table T2 can be generated accurately and simply.

<4. Second Embodiment>
Next, a second embodiment will be described. In the first embodiment, the handy terminal 4 is used for the association processing. However, in the present embodiment, the number display 2 of each product shelf 5 acquires the device code of the electronic tag 3, The handy terminal 4 is not required for the attaching process. Hereinafter, the difference from the first embodiment will be mainly described.

  FIG. 17 is a block diagram showing the overall configuration of the sorting system 10b of the present embodiment. As can be seen from comparison with FIG. 7, in this embodiment, the handy terminal 4 is not required, so the third communication system 400 is not provided, and only the first and second communication systems 200 and 300 are provided. Yes.

  FIG. 18 is a diagram illustrating a state of one commodity shelf 5 according to the present embodiment. Also in the present embodiment, one electronic tag 3 is attached to one container 6. The electronic tag 3 includes an apparatus having the same configuration as that of the first embodiment, and further includes an IC tag (RFID tag) 36 that is an electromagnetic recording element. The IC tag 36 stores a device code related to the device itself.

  On the other hand, the number display device 2 of the present embodiment further includes a tag reader 26 that reads the contents of an IC tag in an apparatus having the same configuration as that of the first embodiment. Since the tag reader 26 can read information without contact from an IC tag existing in a nearby space, the IC of the electronic tag 3 attached to the container 6 with the container 6 placed on the product shelf 5. Information can be read from the tag 36. The device code of the electronic tag 3 is acquired by the number indicator 2 by the function of the tag reader 26. It should be noted that the labels 25 and 35 on which barcodes as identification codes are recorded need not be attached to the number display 2 and the electronic tag 3 of the present embodiment.

  The flow of work and processing using the sorting system 10b of the present embodiment is almost the same as that shown in FIG. 12, but only the association processing (step S3) is different. FIG. 19 is a diagram showing the flow of the association processing (step S3) of the present embodiment. In this figure, the flow on the left side shows the operation of the number indicator 2, and the flow on the right side shows the operation of the host computer 1. In this description as well, a certain product shelf 5 will be described as an attention product shelf.

  First, the device code is acquired from the IC tag 36 of the electronic tag 3 attached to the container 6 placed on the noticeable commodity shelf by the tag reader 26 of the number display 2 fixed to the noticeable commodity shelf. The acquired device code is stored in the memory of the control unit 24 (step S41).

  As described above, the product shelf code related to the product shelf of interest is stored in advance in the memory of the control unit 24. Therefore, the product shelf code and the device code acquired by the tag reader 26 are transmitted from the control unit 24 to the host computer 1 (step S42).

  The transmitted merchandise shelf code and device code are received by the host computer 1 via the display controller 202 and the operation terminal 201 (step S51). Thereafter, as in the first embodiment, one record Re of the correspondence table T2 is generated (step S52), and the history table T3 is updated (step S53).

  The operation of step S41 in which the tag reader 26 acquires the device code is started when there is a readable IC tag 36 in the vicinity of the tag reader 26. Therefore, when the empty container 6 is placed on the noticeable product shelf by the worker P, the association process shown in FIG. 19 is automatically performed. That is, in the present embodiment, the worker P does not need to perform complicated work regarding the association, and completes the association between the product shelf of interest and the electronic tag 3 without any awareness. Will be able to. In terms of cost, since the functions of the number indicator 2 and the electronic tag 3 can be simplified, the first embodiment is preferable.

<5. Third Embodiment>
Next, a third embodiment will be described. In the above embodiment, the electronic tag 3 is used while attached to the container 6. However, in the present embodiment, the electronic tag 8 can be attached to and detached from the number indicator 2, and as shown in FIG. It is designed to be used by being attached to the number indicator 2. Hereinafter, the difference from the first embodiment will be mainly described.

  FIG. 21 is a diagram showing the configuration of the number indicator 2 and the electronic tag 8 of the present embodiment. The number indicator 2 is the same as that of the first embodiment in that it includes a display 21, a completion button 22, a full button 23, and a control unit 24. A slot 27 for mounting is provided.

  Engaging claws 29 urged toward the internal space of the slot 27 are provided on the left and right end portions inside the slot 27, respectively. A connector 28 that is electrically connected to the control unit 24 is provided on the inner upper portion of the slot 27. The engaging claw 29 is embedded in the housing 20 when the removal button 29a at the lower left portion of the housing 20 is pressed.

  The electronic tag 8 is the same as the first embodiment in that it includes a display 81, a control unit 83, and a battery 84, but the infrared communication unit 32 is not provided. In addition, a connector 88 electrically connected to the control unit 83 is provided on the upper portion of the housing 80 of the electronic tag 8, and an engagement groove 89 that is a recessed groove is provided on the upper left and right of the housing 80. .

  When the electronic tag 8 is attached to the number indicator 2, the electronic tag 8 is pushed in from below until the upper portion of the housing 80 of the electronic tag 8 comes into contact with the inner upper portion of the slot 27. As a result, the electronic bill 8 and the number indicator 2 are physically integrated as shown in FIG. In this state, the left and right engaging claws 29 of the slot 27 enter the engaging groove 89 of the electronic card 8, and the electronic card 8 is held so as not to be detached from the number indicator 2 by the urging force of the engaging claw 29. .

  In this state, the connector 88 of the electronic card 8 and the connector 28 of the number indicator 2 are in physical contact, and the control units 83 and 24 of both devices are electrically connected. As a result, data communication is possible between the electronic bill 8 and the number indicator 2.

  When the electronic tag 8 is removed from the number display 2, the removal button 29a is pressed. As a result, the engaging claw 29 of the slot 27 is disengaged from the engaging groove 89 of the electronic card 8 to release the holding state of the electronic card 8 and the electronic card 8 can be removed from the number indicator 2.

  FIG. 22 is a block diagram showing the overall configuration of the sorting system 10c of the present embodiment. In the present embodiment, as in the first communication system 200 in the first embodiment, only one communication system 800 including the operation terminal 201 and the display controller 202 exists. The communication system 800 is responsible for communication between the host computer 1 and the electronic tag 8 as well as communication between the host computer 1 and the number indicator 2. That is, when the electronic bill 8 is mounted on the number display 2, the number display 2 and the electronic bill 8 can communicate with each other. In this state, the communication system 800 is used to connect the host computer 1 to the electronic bill. Data communication is possible for all of the eight.

  When the host computer 1 transmits data to the electronic bill 8, the data is transmitted to the target electronic bill 8 by transmitting the data to the number indicator 2 that is the mounting destination. Since such a communication method is employed, the correspondence table T2 used in the above embodiment is not necessary in the present embodiment. Therefore, the associating process is unnecessary and the history table T3 is not used.

  Next, a sorting operation using the sorting system 10c of the present embodiment will be described. Also in this description, a certain product shelf 5 will be described as attention product shelf. FIG. 23 is a diagram showing a flow of work and processing related to the product shelf of interest in the present embodiment.

  First, the “order variable” relating to the product shelf of interest is set to “1” (step S61). Next, an empty container 6 is placed on the noticeable product shelf by the worker P (step S62). At this time, the unused electronic tag 8 to be attached to the container 6 is not attached to the container 6, but is attached to the number display 2 of the noticeable product shelf as shown in FIG. As a result, the host computer 1 and the electronic tag 8 can communicate with each other (step S63).

  When the electronic bill 8 is mounted on the product shelf of interest, a message to that effect is input to the host computer 1. In response to this, in the host computer 1, the work table T <b> 1 is referred to, and the “store name” and “store code” associated with the product shelf code of the product shelf of interest are acquired by the CPU 11. Then, the “store name”, the “store code”, and the “order variable” at that time are transmitted from the host computer 1 to the electronic tag 8 attached to the product shelf of interest. As a result, as in FIG. 14, the “store name” and “store code” relating to the store associated with the product shelf of interest in the electronic tag 8 and the “usage order” of the own device are displayed ( Step S4).

  Thereafter, as in the first embodiment, until the input for all types of products to be sorted is completed (No in step S67), the barcode of the product is read for each type of product (No. Step S65), product introduction and depression of the completion button 22 (step S66) are repeated.

  If the container 6 is full and the full button 23 is pressed while repeating such operations (Yes in step S68), a predetermined signal is transmitted to the host computer 1 to change the container 6. (In other words, the CPU 11 acquires that the electronic bill 8 to be mounted is to be changed).

  In response to this, the CPU 11 refers to the record R1 related to the product shelf of interest in the work table T1, and extracts the sub-record R2 in which the “order variable” at that time is stored in the “container number” And its contents are acquired. The content of the acquired sub-record R2 indicates information on all products that have been put into the container 6 while the electronic tag 8 is mounted on the product shelf of interest. The contents of the sub-record R2 are transmitted from the host computer 1 to the electronic tag 8 attached to the product shelf of interest. As a result, as in FIG. 15, information on all commodities put into the container 6 in the electronic tag 8 is displayed (step S <b> 69).

  When the product information is displayed, the electronic tag 8 is removed from the number display unit 2 of the product shelf of interest and attached to the container 6 before replacement. As a result, the electronic tag 8 is attached to the container 6 (step S70). Since the electronic tag 8 is driven by the battery 84, the display of the electronic tag 8 is maintained even after being removed from the number display 2. Therefore, various information such as store information can be attached to the container 6.

  When the electronic tag 8 is removed, the “order variable” is incremented (+1) by the CPU 11 (step S71). This “order variable” is the use order of the containers 6 to be placed next, and is also the use order of the electronic bills 8 to be mounted next on the product shelf of interest. In this way, by incrementing the “order variable” in response to the change of the electronic tag 8, the use order of each electronic tag 8 mounted on the product shelf of interest can be acquired.

  Thereafter, a new container 6 is placed on the noticeable commodity shelf (step S62), and a new electronic tag 8 is mounted on the number display 2 of the noticeable commodity shelf (step S63). Then, “store name”, “store code”, and “use order” are also displayed on the new electronic tag 8 (step S64). Thereafter, in the same manner as described above, merchandise is input to the new container 6.

  Also, when the new container 6 is full of products, the full button 23 is pressed, and the operations of steps S69 to S71 are performed, and the electronic bill 8 is inserted into the container 6 while the electronic bill 8 is mounted on the product shelf of interest. Information on all the products is acquired and displayed on the electronic tag 8. Also in this case, the information on the product introduced between the two most recent changes of the electronic tag 8 is acquired as the product introduced into the container 6.

  When the insertion of all types of products is completed (Yes in step S67), it is inserted into the container 6 while the electronic tag 8 mounted on the product shelf of interest is mounted at the same time as in step S69. Information on all the items for sale is acquired and transmitted to the electronic tag 8 for display (step S72). When the product information is displayed, the electronic tag 8 is removed from the product shelf of interest and attached to the last container 6 (step S73).

  As described above, in the sorting system 10c of the present embodiment, the electronic bills 8 can be attached to the respective product shelves 5, and the communication system to the number indicator 2 with respect to the electronic bills 8 mounted on the product shelf 5. Data is transmitted using. For this reason, an associating process or the like is unnecessary, and accurate store information can be attached to the container 6 with a relatively simple configuration.
