Description

  The present invention relates to a merchandise management system that manages the expiration of sales of products that require a freshness management, such as bento, rice balls, bread, milk, etc., and that require a freshness management, that is, a so-called freshness management target product.

  In general, at stores that sell products subject to freshness management such as bento boxes, store staff regularly check the display location of this type of product to check if there is a product that has approached the expiration date, and Product management is performed so that products that have expired are not sold to customers by collecting and discarding them.

  As a system for simplifying this kind of product management, a wireless tag that is attached to a product and stores information related to the product, and information stored in the wireless tag is wirelessly read, and information related to the product is obtained. There has been known a merchandise management system comprising a management device to obtain. In this conventional system, product value information such as the price of the product and date / time information such as a expiration date are stored in advance in a wireless tag attached to each product arranged in the store. Then, the management device wirelessly reads the stored information from the wireless tag attached to each product, and determines and notifies whether there is a product to be discarded based on the current date and time information such as the expiration date It is. (For example, refer to Patent Document 1).

  In addition, the wireless tag attached to each product stores the identification information of the product, and a wireless tag reader is connected to a product registration terminal that processes sales data of the product purchased by the customer. Then, wireless tag information attached to each product put in the shopping basket by the wireless tag reader is read in a non-contact manner, and the product registration terminal acquires identification information of each product from the wireless tag storage information. A product registration processing system that processes sales data of each product based on the product identification information is also known (see, for example, Patent Document 2).

Therefore, by combining the product management system described above with this product sales registration processing system, the product registration terminal obtains the date and time information together with the product identification code of each product from the wireless tag storage information of each product. It was possible to notify the user when there is a product to be discarded based on the date and time, so as not to mistakenly sell the product whose expiration date has been consumed.
JP 2002-83369 A JP 10-49756 A

  By the way, regarding the product collected from the store as the product to be discarded, it is necessary to discard and register the data in the product registration terminal. If this disposal registration is neglected, the sum of the number of products sold and the number of disposals does not coincide with the number of purchases, and it becomes impossible to manage whether the product has been collected due to the expiring expiration date or lost due to shoplifting. So, when a store clerk at this type of store collects a product that is about to expire, it switches the business mode of the product registration terminal from the normal sales registration mode to the discard registration mode in anticipation of the absence of customers. After that, the collected product data is registered one by one in the product registration terminal, and the disposal data is registered in the POS (Point Of Sales) system.

  However, in the past, products registered in the disposal registration mode, so-called disposal registered products, were unconditionally processed as waste products, so the store clerk collected products that were not intended to be discarded by mistake or on purpose. Even if the product was discarded, the product was processed as a discarded product.

  The present invention has been made based on such circumstances, and the purpose of the present invention is that only products that should be discarded can be registered for disposal due to expiration of the sales period, and products that are not subject to disposal are erroneously collected and registered for disposal. It is an object of the present invention to provide a merchandise management system that can prevent a store clerk from unjustly collecting merchandise that is not subject to disposal, registering it for disposal, and dressing the merchandise.

  In order to solve the above problems, the product management system of the present invention attaches a wireless tag to each product, and stores at least the product identification information corresponding to the wireless tag. In addition, a display unit tag recognizing unit that wirelessly reads stored information from a wireless tag attached to each product displayed in the display unit is provided in the product display unit in which each product is displayed. Then, from the RFID tag storage information read by the display unit tag recognition means, information on the sales deadline of each product displayed in the product display unit is acquired, and a list of products whose sales deadline has passed is created. Output a list of products whose sales have expired. In addition, an input means for inputting product identification information is provided. Then, a search is made as to whether or not the product identified by the identification information input by the input means exists in the sales expired product list, and if present, the product is processed as a discarded product. It is.

  According to the present invention having such a configuration, since only the products listed in the sales expired product list can be processed as data for disposal, products that are not subject to disposal may be accidentally collected and registered for disposal, or intentionally disposed of. It is possible to provide a merchandise management system that can prevent a store clerk from collecting fraudulent merchandise, registering it for disposal, and dressing it.

The best mode for carrying out the present invention will be described below with reference to the drawings.
In this embodiment, as shown in FIG. 1, a wireless tag 2 is attached to every product including a freshness management target product 1 such as lunch box, rice ball, bread, milk, etc. This is a case where the product management system of the present invention is applied to a product registration processing system in which sales data of each product is processed based on the product identification information stored in the tag 2. Incidentally, in FIG. 1, the code | symbol 3 has shown the value label. The priced label 3 is usually printed with the date of processing, the expiration date, etc. in addition to the price.

  The wireless tag 2 is also referred to as an RFID tag, a wireless ID tag, or the like. As shown in FIG. 2, a coiled loop antenna 21 formed along the outer periphery of the belt-shaped substrate and an LSI chip formed on the substrate. 22. The LSI chip 22 rectifies and stabilizes the modulated radio wave received by the loop antenna 21 to demodulate the modulated radio wave and send it to the control unit 26. Modulation unit 25 that modulates data sent from demodulation unit 24 and control unit 26 and sends the data to loop antenna 21, writes data demodulated by demodulation unit 24 to memory 27, and reads transmission data from memory 27 A control unit 26 for sending to the modulation unit 25 and a non-volatile memory 27 are included.

  In the memory 27, a wireless ID area 27a that stores a unique wireless ID (RFID) assigned and set by the manufacturer at the manufacturing stage of the wireless tag 2, and a user area 27b in which a user can write arbitrary data. Is formed. In the user area 27b of the wireless tag 2 attached to each product, a product code unique to the product, which is one piece of product identification information, is stored in advance. In addition to the product code, sales date information is stored in the user area 27b for the freshness management target product 1 for which the expiration date is set. The sales deadline information is information on the date or time that must be discarded because the corresponding product is about to expire, and in the case of the freshness management target product 1 for which the expiration date is set in units of time, for example, consumption A time 3 hours before the deadline time is preset as sales deadline information. In addition, in the case of the freshness management target product 1 for which the expiration date is set on a date basis, for example, the date on the same day as the expiration date is preset as the sales expiration date information.

  FIG. 3 is a schematic diagram showing a system configuration of the present embodiment. In the present embodiment, one or more POS terminals 5 functioning as product registration terminals and a store server 6 operating as a host machine of the POS terminals 5 are connected to a LAN (Local Area Network) 4 laid in the store.

And a function for creating a list of products whose sales deadline has passed and a function for transmitting the created list of products with expired sales to the POS terminal 5 via the LAN 4 which is a communication means.

  In order to realize each of the above functions, the store server 6 stores a product information file 12 that stores information on each product sold in the store, an attribute information file 13 that stores information on attributes that classify each product, and each product display. Is provided with a recognition device information file 14 for storing information on display shelf tag recognition devices 11A, 11B,... Provided on the shelves 10A, 10B,. As shown in FIG. 4A, the merchandise information file 12 includes a merchandise information record including at least data items such as a merchandise code, an attribute code, a merchandise name, a unit price, a sales score, a sales price, a discard score, and a discard price. Accumulated. As shown in FIG. 5B, the attribute information file 13 stores attribute information records including at least attribute code, attribute name, discard management flag, sales score, sales amount, discard point, and discard amount data items. Has been. The recognition device information file 14 stores a recognition device information record including a recognition device ID and an installation location name, as shown in FIG.

In the attribute information record, the discard management flag is a flag that is set when the product with the attribute classified by the corresponding attribute code is the freshness management target product 1.
In the recognition device information record, the recognition device ID is an identification code assigned and set differently for each display shelf tag recognition device 11A, 11B,. The installation location name is an identification name of a merchandise display shelf (for example, lunch box corner, pan corner, fresh food) from which information of the wireless tag 2 can be read by the display shelf tag recognition devices 11A, 11B,. Corner).

  As shown in FIG. 5, the display shelf tag recognition devices 11A, 11B,... Have an interface unit 111 with a store server 6 that is a host device, a nonvolatile memory unit 112, a control unit 113, and a control unit 113. A modulation unit 114 that modulates the data given from the signal into a modulation signal suitable for wireless communication, a transmission amplifier 115 that amplifies the modulation signal and emits it as an inquiry radio wave from the antenna 116, and reception that amplifies the radio signal received by the antenna The amplifier 117 and a demodulator 118 that demodulates data from the amplified radio wave signal and supplies the demodulated data to the controller 113.

When the control unit 113 receives a command from the store server 6 via the interface unit 111, the control unit 113 periodically sends predetermined data to the modulation unit 114, and takes in the data demodulated by the demodulation unit 118. It has a function of sending the data to the store server 6 via the interface unit 111 as a tag recognition response together with the recognition device ID.

  Incidentally, the accounting tag recognition device 7 is also configured in the same manner as the display shelf tag recognition devices 11A, 11B,. However, the POS terminal 5 is connected to the interface unit as a host device. The antenna is provided so that the upper part of the checkout counter 8 has a sensitivity range.

  FIG. 6 is a block diagram showing a main configuration of the store server 6. The store server 6 includes a CPU (Central Processing Unit) 61 that constitutes a control unit body, a ROM (Read Only Memory) 62 in which a program for controlling the CPU 61 and the like are stored in advance, and various types of data that are freely read by the CPU 61. A RAM (Random Access Memory) 63 in which a data area is formed, a clock unit 64 as time measuring means for measuring the current date and time, a LAN controller 65 for controlling data communication performed via the LAN 4, and the product information file 12 , An attribute information file 13, a recognition device information file 14 and the like, an HDD (Hard Disk Drive) device 66, and an interface 67 for controlling data communication with the display shelf tag recognition devices 11A, 11B,. .

  In the store server 6 having such a configuration, as shown in FIG. 7, the memory information (RFID, product code, sales deadline information) of the wireless tag 2 attached to the freshness management target product 1 and the display location of the product 1 A sales expiration list memory 631 is stored in the RAM 63 so as to store the information indicating the corresponding information.

  Therefore, the store server 6 is programmed so that the CPU 61 repeatedly executes the timer interrupt process shown in the flowchart of FIG. 8 in response to the input of a timer interrupt signal generated at intervals of 1 minute, for example.

  That is, when the timer interrupt process is started, the CPU 61 first obtains the current date and time (year / month / day / hour) counted by the clock unit 64 as ST (step) 1. Then, as ST2, it is determined whether or not the current time coincides with a preset expiration monitoring time. Here, the expiration monitoring time is the time when about several minutes have elapsed from the time of the sales expiration date / time set for each freshness management target product 1, for example, the time of the sales expiration date / time is 0:00, 3:00, 6:00,. When the time is set in units of 3 hours, the time every 3 hours is set in advance in the ROM 62 or RAM 63, such as 0:01, 3:01, 6:01.

  In ST2, if the current time does not coincide with the expiration monitoring time, the CPU 61 ends this timer interrupt process. On the other hand, when the current time matches the expiration monitoring time, the CPU 61 clears the sales expiration list memory 631 as ST3. Thereafter, the CPU 61 outputs an activation command to each display shelf tag recognition device 11A, 11B,... As ST4. In ST5, a tag recognition response from each of the display shelf tag recognition devices 11A and 11B is waited.

  Here, each time the CPU 61 receives a tag recognition response from any of the display shelf tag recognition devices 11X (X indicates any one of A, B...), The CPU 61 concretely shows in FIG. The sale expiration product search process shown is executed. First, in ST11, the recognition device ID included in the tag recognition response, that is, the recognition device ID set in the display shelf tag recognition device 11X of the response transmission source is detected. Then, the recognition device information file 14 is searched as ST12, and the installation location name information stored corresponding to the recognition device ID is acquired.

  Next, in step ST13, the CPU 61 detects the first recognition tag information from the tag recognition response (RFID, product code, and sales deadline information in the case of the freshness management target product 1, and RFID and product code in the other cases). . In step ST14, the product code is acquired from the recognition tag information.

  Next, the CPU 61 searches the product information file 12 using the product code acquired in ST14 as ST15, and acquires the attribute code from the product information record in which the product code is set. In ST16, the attribute information file 13 is searched with this attribute code, and the discard management flag of the attribute information record in which the attribute code is set is checked. Here, if the discard management flag is not set, the product with the attribute classified by the corresponding attribute code is not the freshness management target product 1, and thus the CPU 61 proceeds to the process of ST20.

  On the other hand, when the discard management flag is set, the product with the attribute classified by the corresponding attribute code is the freshness management target product 1, so the CPU 61 recognizes the recognition tag detected in ST13 as ST17. Get sales deadline information from information. Then, in ST18, it is determined whether or not the sales deadline date set by this sales deadline information has already passed. If the current date / time has not passed the sales deadline date / time, the process proceeds to ST20.

  On the other hand, when the current date / time has passed the sales deadline date / time, the CPU 61 obtains the RFID of the identification tag information, the product code and the sales date / time information detected in ST13 as ST19, and the processing in ST12. The installation location name information is sequentially stored in the sales expiration list memory 631. Thereafter, the process proceeds to ST20.

  In ST20, the CPU 61 determines whether or not there is next recognition tag information in the tag recognition response. If there is next recognition tag information, the process returns to ST13, the next tag recognition information is detected, and the processes of ST14 to ST20 are repeatedly executed. In this way, all the recognition tag information included in the tag recognition response is sequentially detected, and each process of ST14 to ST20 is executed. If it is determined in ST20 that there is no next recognition tag information, the CPU 61 The expired product search process is terminated.

  Here, the store server 6 sells each freshness management target product 1 displayed on the product display shelves 10A, 10B... From the storage information of the wireless tag 2 read by the display shelf tag recognition devices 11A, 11B,. Expired product list creation means is provided for acquiring information on the due date and creating a list of freshness management target products 1 whose sales due date has passed on the sales expired list memory 631.

Returning to FIG.
When the sales expired product search process for any of the display shelf tag recognition devices 11X that have received the tag recognition response is terminated, the CPU 61 determines whether the tag recognition process is terminated or not in ST7. Here, when a tag recognition response is received from all the display shelf tag recognition devices 11A, 11B,... To which the start command has been given, or when a predetermined time has elapsed after the start command is output, the CPU 61 determines that the tag recognition process has ended. to decide. If it is determined that the tag recognition process has ended, the CPU 61 determines whether there is a product whose sales have expired in ST8. Here, if at least one piece of data of RFID, product code, sales time limit information, and display place name information is stored in the sales time limit list memory 631, it is determined that there is a sales time-limited product. If there is an expired sale item, the CPU 61 reads the sale expiration list data stored in the sale expiration list memory 631 as ST9, and transmits it to the POS terminal 5 via the LAN 4, and this timer interruption process Exit. If there is no product whose sales have expired, the CPU 61 ends the current timer interrupt process without performing the process of ST9.

  Here, the store server 6 includes a list transmission unit that transmits the sales expired product list created by the expired product list creation unit via the LAN 4 as a communication unit.

  FIG. 10 is a block diagram showing a main part configuration of the POS terminal 5. The POS terminal 5 includes a CPU 57, a ROM 52, a RAM 53, a clock unit 54, a LAN controller 55, and an interface 56 that controls data communication with the accounting tag recognition device 7, a keyboard 57, an operator display 58, a customer display 59, The printer includes a printer 510 for receipt / journal printing, a drawer 511, and the like.

  The keyboard 57 is particularly provided with a tag key K1 and a fastening key K2. The tag key K1 is a key for instructing activation of the accounting tag recognition device 7. The closing key K2 is a key for declaring the closing of the sales registration process and the disposal registration process.

  The operator display 58 displays various data for an operator who operates the POS terminal 5, and in this embodiment, a display with a touch panel is used.

  In the POS terminal 5 having such a configuration, as shown in FIG. 11, a recognition tag information memory 531 capable of storing each data of RFID, product code and sales deadline information, and each data of product code and sales deadline information can be stored. Disposal error memory 532, expired product memory 533 that can store RFID, product code, sales deadline information, display location name information, discarded flag, and product registration flag data, product code, unit price, points, amount A transaction memory 534 capable of storing each data, a flag memory 535 for storing various flag data of a discard registration flag, an icon display flag, a list display flag, a discard registration flag, a discard error flag, and a product registration flag are stored in the RAM 53. Is formed.

  When the POS terminal 5 is instructed to execute a registration job from among various job menus by a key operation on the keyboard 57 or a touch operation on a menu screen displayed on the operator display 58, the flowchart shown in FIG. Programmed to perform processing.

  That is, when the registration work process is started, the CPU 51 first performs an initialization process of the RAM 53 and resets various flag data stored in the flag memory 525 to “0” (ST21). Next, until the icon display flag is set (ST24), the CPU 51 performs key operation of the keyboard 57 (ST22), or the sales expiration list transmitted from the store server 6 via the LAN 4 Waiting to receive data (ST23).

  Here, when the sales expiration list data is received (YES in ST23), the CPU 51 executes the expiration list reception process specifically shown in the flowchart of FIG. That is, the received sales expiration list data is stored in the expiration product memory 533. At this time, all the discarded flags corresponding to each data in the expired product memory 533 are reset to “0”. In addition, as shown in FIG. 18, an expiration icon A1 is displayed on the product registration screen G1 displayed on the operator display 58 to notify the operator that there is a sales expiration product. Then, the icon display flag in the flag memory 535 is set to “1”.

  When the POS terminal 5 receives the sales expiration list data from the store server 6 via the LAN 4, the POS terminal 5 includes notification means for informing the operator of the POS terminal 5 that there is an expired sale item by displaying the expiration icon A <b> 1. Yes.

  Thus, when the icon display flag is set, the CPU 51 receives the next sales expiration list data until the key display on the keyboard 57 is performed (ST22) until the list display flag is set (ST27). (ST23), it waits until the expiration icon A1 on the product registration screen G1 is touched (ST25).

  If it is detected that the expiration icon A1 has been touched (YES in ST25), the CPU 51 determines whether or not a product registration flag is set (ST26). If it is set (YES in ST26), the touch operation of the expiration icon A1 is invalidated.

  On the other hand, when the merchandise registration flag is reset to “0” (NO in ST26), the CPU 51 executes an expiration icon input process specifically shown in the flowchart of FIG. That is, the expired product list screen G2 is created based on the data stored in the expired product memory 533, and the expired product list screen G2 is displayed on the operator display 58 as shown in FIG. Also, the discard registration flag in the flag memory 535 and the list display are set to “1”, respectively.

  Incidentally, the expired product list screen G2 displays a product name, a sales expiration date and time, a display location name, a disposal status information list L1 indicating whether the product has been discarded, and a close icon A2. Here, the product name in the list L1 is a product name set in the product information file 12 of the store server 6 corresponding to the product code stored in the expired product memory 533. The discard status information is displayed as “discarded” when the corresponding discard flag is set to “1”.

  Here, the POS terminal 5 is provided with list output means for causing the operator display 58 to display the sales expired product list L1. Then, the list output unit is configured to notify the user of the notification operation by the notification unit, that is, the display of the expiration icon A1, that is, the operator performed a confirmation operation, that is, the touch operation of the expiration icon A1. Is output.

  When the list display flag is set in this manner, the CPU 51 determines whether the key operation of the keyboard 57 is performed (ST22), the next sales expiration list data is received (ST23), or the close icon of the expiration product list screen G2 It waits for A2 to be touched (ST28).

  If it is detected that the close icon A2 is touched (YES in ST28), the CPU 51 executes a close icon input process specifically shown in the flowchart of FIG. That is, the expired product list screen G2 is deleted, and the screen of the operator display 58 is returned to the product registration screen G1. Further, the discard registration flag in the flag memory 535 and the list display are reset to “0”, respectively.

  Next, the CPU 51 searches the expired product memory 533 to determine whether there is data for which the discarded flag is not set to “1”. When there is no data for which the discarded flag is not set to “1”, the CPU 51 clears the expired product memory 533. Further, the expired icon A1 displayed on the product registration screen G1 is deleted. Furthermore, the icon display flag in the flag memory 535 is reset. On the other hand, if there is even one data for which the discarded flag is not set to “1”, the CPU 51 does not execute the above process. Therefore, the expiration icon A1 remains displayed on the product registration screen G1.

  Here, the POS terminal 5 includes list output switching means for switching whether or not to display the sales expired product list L1 on the operator display 58.

  When a key operation on the keyboard 57 is performed (YES in ST22), the CPU 51 executes a key input process corresponding to the operation key.

  FIG. 16 is a flowchart showing the main part of the tag key input process executed in response to the operation of the tag key K1. That is, when detecting that the tag key K1 is operated, the CPU 51 first clears the transaction memory 534, the recognition tag information memory 531 and the discard error memory 532 as ST31. Next, the CPU 51 outputs a start command to the accounting tag recognition device 7 as ST32. In ST33, a tag recognition response from the accounting tag recognition device 7 is awaited.

  Here, when receiving the tag recognition response from the accounting tag recognition device 7 within a predetermined time, the CPU 51 determines all the recognition tag information included in the tag recognition response as ST34 (RFID in the case of the freshness management target product 1). The product code and the sales deadline information (RFID and product code in other cases) are detected and stored in the recognition tag information memory 531 in order.

  Here, the POS terminal 5 includes an accounting tag recognizing device 7 as an input means for a product code which is product identification information.

  Next, the CPU 51 determines whether or not a discard registration flag is set in ST35. Here, if the discard registration flag is not set, it is a normal sales registration business, and therefore the CPU 51 sets the product registration flag to “1” and then stores each product code stored in the recognition tag information memory 531. Based on the above, the batch sales registration processing of the sales product is executed. For example, the unit price set corresponding to each product code is read from the product information file 12, and sales transaction data of the product code, unit price, points (= 1), and amount (unit price × points) are sequentially stored in the transaction memory 534. Processing to store is performed.

  On the other hand, if the discard registration flag is set, it is a discard registration operation, and therefore the CPU 51 once resets a predetermined read counter n to “0” as ST36 and then sets the read counter n as “1” as ST37. "Only count up. And from the recognition tag information memory 531, No. The recognition tag information stored in the area of n (n is the value of the read counter) is acquired.

  Here, as ST39, No. 1 is recognized from the recognition tag information memory 531. If the recognition tag information of n can be acquired, the CPU 51 determines whether or not the data matching the recognition tag information and the RFID, the product code, and the expiration date is stored in the expired product memory 533 in ST40. If the product is stored, the product to which the wireless tag 2 of the recognition tag information is attached is an expired sale expired product, and therefore the CPU 51 sets data matching the recognition tag information in the expired product memory 533 as ST41. Is set to “1”. Further, as ST42, the unit price set corresponding to the product code of the recognition tag information is read from the product information file 12, and the discard transaction data of the product code, the unit price, the score (= 1), and the amount (unit price × point) are stored. Store in the transaction memory 534. Furthermore, “discarded” is displayed in the discard status area of the data related to the product in the sales expired product list L1 displayed on the operator display 58 as ST43.

  Here, the POS terminal 5 searches whether or not the product identified by the product code input via the accounting tag recognition device 7 exists in the sales expired product list L1. Disposal processing means for processing the product as a discarded product is provided. The discard processing means is valid when the discard registration flag is set, that is, during the period when the sales expired product list L1 is displayed on the operator display 58. In addition, a product that has been data-processed as a discarded product by the disposal processing means is clearly indicated as “discarded” on the sales expired product list L1.

  Thereafter, the CPU 51 determines whether or not the discard registering flag in the flag memory 535 is set in ST44. If the discard registration flag is reset to “0”, the discard registration flag is set to “1” in ST45. If the discard registration flag is already set to “1”, the process of ST45 is not executed.

  Thereafter, the CPU 51 returns to the process of ST37, and if the read counter N is further incremented by “1”, the process after ST38 is executed again. That is, from the recognition tag information memory 531, no. If the recognition tag information stored in the area n is acquired, it is determined whether data matching the recognition tag information is stored in the expired product memory 533, and it is confirmed that it is stored Each process of setting and discarding corresponding discard flag and discard transaction data, and displaying “discarded” is executed.

  The No. of the recognition tag information memory 531 When it is confirmed that the matching tag information acquired from the area of n and the data that coincides with the RFID, the product code, and the expiration date are not stored in the expired product memory 533, the wireless tag 2 of the recognition tag information is attached. Since the merchandise is a merchandise that is not to be discarded, the CPU 51 stores the merchandise code of the recognition tag information and the sales deadline information in the discard error memory 532 as ST46. Then, in ST47, it is determined whether or not the discard error flag of the flag memory 535 is set. If it has been reset, the discard error flag is set to “1” in ST48. Thereafter, the CPU 51 returns to the process of ST37, further increments the read counter N by “1”, and executes the processes after ST38 again.

  In this way, the discard registration process of ST41, 42, 43 or the discard error process of ST46 is executed for all the recognition tag information stored in the recognition tag information memory 531. If it is confirmed that there is no N recognition tag information, the CPU 51 displays a message such as “completed discard registration” on the operator display 58 as ST49, and ends the tag key input process.

  FIG. 17 is a flowchart showing the main part of the closing key input process executed by operating the closing key K2. That is, when detecting that the closing key K2 has been operated, the CPU 51 first determines whether or not the discard registration flag is set in ST51. Here, when the discard registration flag is not set, it is a normal sales registration work, and therefore the CPU 51 executes a sales registration closing process. For example, sales transaction data stored in the transaction memory 534 is transmitted to the store server 6 via the LAN 4. The printer 510 is driven to print and issue a sales receipt based on the contents of the sales transaction data. Further, the drawer 511 is opened. Thereafter, the CPU 51 resets the product registration in-progress flag to “0”, and ends the closing key input process at the time of sales registration work.

  On the other hand, if the discard registration flag is set, it is a discard registration operation, and therefore the CPU 51 determines whether or not the discard registration flag is set in ST52. If set, since the data subjected to the discard registration process is stored in the transaction memory 534, the CPU 51 drives the printer 510 as ST53 and stores the discard transaction data stored in the transaction memory 534. Print the contents on receipt paper. In ST54, the receipt sheet is cut and issued as a waste registration receipt. In ST55, the discard transaction data is transmitted to the store server 6 via the LAN 4. Thereafter, the discard registration flag is reset as ST56. If the discard registration flag is not set in ST52, the processes of ST53 to ST56 are not executed.

Next, the CPU 51 determines whether or not a discard error flag is set in ST57. If set, since the data subjected to the discard error processing is stored in the discard error memory 532, the CPU 51 drives the printer 510 as ST58 and stores the product code stored in the discard error memory 532. The product name and sales deadline information corresponding to are printed on the receipt paper. In ST59, the receipt sheet is cut and issued as a discard error receipt. Thereafter, the discard error flag is reset as ST60. If the discard error flag is not set in ST57, the processes of ST58 to ST60 are not executed.
Thereafter, the CPU 51 deletes the discard registration completion message displayed on the operator display 58 as ST61, and ends the closing key input process.

  Incidentally, in the store server 6 that has received the sales transaction data transmitted from the POS terminal 5 via the LAN 4, the sales score and sales amount data of the product information file 12 corresponding to the product code existing in the sales transaction data. Is added to the sales transaction data score and amount. Similarly, in the store server 6 that has received the discard transaction data, the discard transaction data score and amount are added to the discard score and discard amount data of the product information file 12 corresponding to the product code existing in the discard transaction data. It is to be added.

  Thus, in the present embodiment, the wireless tag 2 is attached to each product, and the RFID 27 and the product code are stored in the memory 27 of the wireless tag 2 as identification information of each product. Further, in the memory 27 of the wireless tag 2 attached to the freshness management target product 1 such as a lunch box, the sales deadline information is stored together with the product code.

  Further, display shelf tag recognition devices 11A, 11B,... Are provided on the product display shelves 10A, 10B,. Each of the display shelf tag recognition devices 11A, 11B,... Operates periodically under the control of the store server 6 and is attached to each product displayed on the product display shelves 10A, 10B,. The memory information of the wireless tag 2 is read and transmitted to the store server 6.

  The store server 6 obtains the sales deadline information of the freshness management target product 1 from the memory information of each wireless tag 2 recognized by each display shelf tag recognition device 11A, 11B,... Check for expired products. If there are products whose sales have expired, a list is created. Then, the list data of the products whose sales have expired is transmitted to the POS terminal 5 via the LAN 4.

  On the other hand, when the list data of expired products is sent from the store server 6 via the LAN 4 to the POS terminal 5 in which the normal sales registration work is executed, the expired icon A1 is displayed on the operator display 58. Is done. Thereby, the operator of the POS terminal 5 can easily recognize that there is an expired product.

  Then, the operator who recognizes that there is a product whose sales have expired touches the expiration icon A1 in anticipation of when the customer performing the transaction is interrupted. Then, the expired product list screen G2 is displayed on the operator display 58.

  For example, assume that the expired product list screen G2 in the screen example shown in FIG. 19 is displayed. It should be noted that the discarding state is not discarded (blank). From the sales expired product list L1 on this screen G2, the operator can know that there are 4 items of “A rice ball”, “B lunch”, “C bread”, and “D milk” as sales expired products. Therefore, the operator goes to the corresponding display place and collects products whose sales have expired. At this time, for example, when a plurality of “A rice balls” are displayed in the lunch box corner, “A rice balls” whose expiry date and time printed on the priced label 3 are within 3 hours from the current date and time are collected.

  The operator who has collected the products whose sales have expired places the collected products on the checkout counter 8 and operates the tag key K1 of the POS terminal 5. The collected products may or may not be put in the shopping basket 9. When the tag key K1 is operated, the transaction tag recognizing device 7 is operated, and the memory information of the wireless tag 2 attached to each product placed on the checkout counter 8 is collectively read. Then, it is checked whether or not the memory information exists in the list data of the products whose sales have expired.

  Here, when the memory information is present in the list data of the expired product, the discard transaction data is generated based on the product code of the memory information and stored in the transaction memory 534. In addition, “Discarded” is displayed in the discard status area of the product name corresponding to the product code in the list L1 displayed on the expired product list screen G2. On the other hand, if the memory information does not exist in the list data of the expired product, the product code and the sales date information of the memory information are stored in the discard error memory 532.

  Thus, when the check is completed for the memory information of all the wireless tags 2 recognized by the accounting tag recognition device 7, a discard registration completion message is displayed on the operator display 58. Therefore, the operator operates the closing key K2. Then, when the discard transaction data is stored in the transaction memory 534, the discard transaction data is transmitted to the store server 6, and the discard data of the corresponding product is cumulatively processed. In addition, a disposal registration receipt is printed and issued. When data is stored in the discard error memory 532, a discard error receipt is printed and issued based on this data. Then, the discard registration completion message is deleted.

  Therefore, the operator discards the collected products for which data is printed on the disposal registration receipt because they are products whose sales have expired. On the other hand, products whose data are printed on the disposal error receipt are returned to the product display shelf because they are not expired products.

  For example, it is assumed that an operator who has viewed the sales expired product list L1 shown in FIG. 19 erroneously collects “A Onigiri” whose sales date / time has not yet passed even though “A Onigiri” has the same product code. In this case, the recognition tag information of “A rice ball” recognized by the accounting tag recognition device 7 and the recognition tag information of “A rice ball” included in the list data of products whose sales have expired coincide with those of the product codes that coincide with each other. And the sales deadline information do not match, so the data is printed on the disposal error receipt. Therefore, it is possible to prevent a mistake that a product that is not a sales expiration product is erroneously collected and discarded.

  When the discard registration completion message is deleted, the operator touches the close icon A2 on the expired product list screen G2. Then, the expired product list screen G2 is deleted, and the product registration screen G1 is restored. At this time, when all the discarded flags of the data stored in the expired product memory 533 are set to “1”, that is, when all the sales expired products are collected, the expired icon A1 is deleted. However, if at least one of the data stored in the expired product memory 533 includes data for which the discarded flag is not set to “1”, the expired icon A1 is continuously displayed. Thereby, the operator can recognize that the collection of the expired product has not been completed.

  As described above, according to the present embodiment, only the products listed in the sales expiration product list L1 created in the store server 6, that is, the products to be discarded due to the sales expiration, can be discarded and registered. Therefore, it is possible to prevent fraud by store employees who mistakenly collect and register a product that is not subject to disposal, or intentionally collect a product that is not subject to disposal and register it for disposal. Can do.

  In addition, simply placing the product collected as an expired product on the checkout counter 8 and operating the tag key K1 and the closing key K2 allows the collected product to be registered for disposal. It is possible to simplify the time and labor required for the waste registration work as compared with the conventional method in which one product input operation is performed and the waste registration is performed.

  In addition, when the expiration date icon A1 is touched to display the sales expiration product list L1 while the normal sales registration operation is being executed, the operation is switched to the disposal registration operation. Further, when the close icon A2 on the expired product list screen G2 is touched and the sales expired product list L1 is deleted, the sales registration service is restored. Therefore, since a complicated mode switching operation from the sales registration work to the disposal registration work is not required, the operability can be improved also in this respect.

  In the embodiment described above, the sales deadline information of the product is stored in the wireless tag 2 attached to each freshness management target product 1, but for example, each freshness management target product 1 is attached. By creating a database that stores and stores the product code and sales deadline information of the product corresponding to the RFID of the wireless tag 2, the product code and sales deadline information can be omitted from the wireless tag 2.

  Further, in the above-described embodiment, a disposal state area is provided in the sales expired product list L1, and “discarded” is displayed for the product for which the discarded flag is set in ST43 of the tag key input process, and data processing is performed as a discarded product. However, the data of the product for which the discarded flag is set may be deleted from the sales expired product list L1. In this case, the discard state area can be omitted from the sales expired product list L1.
