Description

  The present invention relates to a POS system for registering purchased products.

  In retail stores such as supermarkets, devices (so-called cash registers) such as POS (Point of Sales) registers are used for registration and settlement of products purchased by customers. The following method is known as a method for capturing an image of registration operation in the POS register and confirming the image.

First, an image obtained by imaging the vicinity of the POS register is recorded, and the recorded image data and the receipt number when the product is registered are stored in association with each other. Thereafter, the receipt number input is received, and the image data associated with the receipt number is displayed (for example, see Patent Document 1).
JP 2006-48466 A

  In the technique disclosed in Patent Document 1, by specifying a receipt number, it is possible to confirm image data obtained by imaging the product registration operation. However, when it is desired to confirm image data obtained by imaging an operation with a high probability of fraud among image data obtained by imaging a registration operation, all recorded image data must be confirmed. Therefore, there has been a problem that image data obtained by imaging an operation with a high probability of fraud cannot be efficiently confirmed.

  The present invention has been made in view of the above points, and an object thereof is to provide a POS system capable of efficiently confirming image data obtained by imaging an operation with a high probability of fraud.

  The present invention provides a POS system including a product registration device for registering a purchased product, an identification information reading unit that reads the identification information of the purchased product, a reading operation of the purchased product, or a purchased product that has been read. A detection unit that detects an operation in which a purchased product before being placed or read at a predetermined location is taken out from the predetermined location, and an imaging unit that captures the registration processing operation of the purchased product in the vicinity of the product registration device And at least when the product detected by the detection unit is not read, a storage unit that stores the image data captured by the imaging unit at that time so as to be extractable, and the storage unit stored in the storage unit A POS system comprising: a reading unit that reads image data; and a display unit that displays the image data read by the reading unit. That.

  Thereby, it is detected that the reading operation has been performed, but it is possible to efficiently confirm an image obtained by capturing an operation in which the product identification information is not read. For example, the identification information attached to the product is intentionally hidden so that the identification information is not read, or the reading operation is performed by buying the direction of the product so that the identification information does not face the reading unit. By storing image data that captures an operation with a high probability of fraud such as by performing extraction, it is possible to efficiently confirm an image that captures an operation with a high probability of fraud.

  In the POS system of the present invention, the identification information reading unit is a bar code reader, the detecting unit detects a reading operation of the purchased product, and the detecting unit is provided in the vicinity of the bar code reader. It is characterized by.

  As a result, since there is a detection unit in the vicinity of the barcode reader, if an operation for registering purchased products using the barcode reader is performed, the detection unit will always detect it. Even in such a case, the operation can be reliably detected.

  In addition, the present invention includes a latching portion that spreads and latches a shopping bag into which the merchandise registered for the merchandise is input, and the detection unit detects an operation of placing the purchased merchandise in a predetermined place. In the POS system, the detection unit is provided in the hooking portion, and performs the detection when the product is located in an opening of a shopping bag hung on the hooking portion.

  Thereby, it can be detected that the product is located in the opening of the shopping bag into which the registered product is always put. Therefore, since it becomes possible to reliably detect that a product has entered the shopping bag, it is possible to reliably obtain detection information relating to the product to be registered.

  In the POS system of the present invention, the detection unit detects an operation of placing or taking out the purchased product at a predetermined location, and is a weighing unit disposed at a position where the product before the product registration is placed. The detection is performed based on a change in the weight value output from the weighing unit or the weight value output from the weighing means disposed at the position where the product after the product registration is placed.

  As a result, it is possible to detect an operation for taking out a product for product registration from a place where the product before product registration is placed, or an operation for placing the product after product registration in a predetermined location. It is possible to reliably obtain detection information relating to a product that should be registered.

  The present invention further includes a purchase information storage unit that identifies and stores registration information of purchased products for each transaction, and the reading unit captures the image data when the display unit displays the image data. In the POS system, the registration information in the transaction is read from the purchase information storage unit, and the display unit displays the image data and the registration data read by the reading unit.

  Thereby, since registration information can be displayed with the image which imaged operation with high probability of fraud, it can be checked more certainly whether purchase goods were registered correctly.

  According to the present invention, it is possible to efficiently perform an operation with a high probability of fraud by storing in an extractable manner image data obtained by imaging an operation that has been detected by the detection unit but has not been read product identification information. The captured image data can be confirmed.

(First embodiment)
Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing a configuration of a POS system according to the first embodiment of the present invention. FIG. 2 is a diagram showing the appearance of the self-register device 1 and the camera 2 in the first embodiment of the present invention. FIG. 3 is a diagram showing an electrical block diagram of the self-register device 1 in the present embodiment.

  As shown in FIG. 1, the POS system includes a self-register device 1, a camera 2 (imaging unit), and a management device 3. The self-register device 1, the camera 2, and the management device 3 are connected by a LAN (Local Area Network) or the like and can communicate with each other.

  The self-register device 1 is a device in which a customer registers a purchased product, and includes a CPU (Central Processing Unit) 10 (determination unit, extraction unit, reading unit) and a hard disk unit 11 (storage unit, image). Storage unit), RAM (Random Access Memory) 12, display unit 13, speaker unit 15, receipt printing unit 16, barcode scanner 17, electronic money reader / writer 18, and communication unit 19 A camera connection unit 20, a detection sensor 21, and a clock unit 22. The display unit 13, the speaker unit 15, the receipt printing unit 16, the barcode scanner 17 (identification information reading unit, barcode reader), the electronic money reader / writer 18, and the detection sensor 21 (detection unit) This appears on the exterior of the self-register device 1.

  The camera 2 images a product registration operation including a product scanning operation performed by the customer with the barcode scanner 17. Further, in the case of operation in which a product is taken out from a shopping basket containing products before product registration and scanned, and the product after product registration is placed in a predetermined place, the series of operations are imaged. The management device 3 has a hardware configuration equivalent to that of a normal PC (Personal Computer, personal computer), and includes a CPU, a storage unit, and a display unit that is a touch panel. The storage unit of the management device 3 stores image data picked up by the camera 2, image files, result files transmitted from the self-register device 1, product files, and the like. As for the product file, when there is a change in the price of the product every day, the changed data in the product file is transmitted from the management device 3 to the self-register device 1.

  Next, with reference to FIG. 3, each part with which the self-register apparatus 1 is provided is demonstrated. The CPU 10 executes various calculations and controls each part of the self-register device 1 based on the calculation results. The hard disk unit 11 is a readable / writable large-capacity storage device. The hard disk unit 11 stores a program for realizing each function of the self-register device 1, a product file transmitted from the management device 3, a purchase record file, and the like.

  The RAM 12 is a readable / writable storage device. The RAM 12 stores various data used when the CPU 10 performs processing, such as data read by the CPU 10 from the hard disk unit 11, data during product registration, and the like.

  The display unit 13 is configured by using an image display device such as a liquid crystal display, and is provided at a position facing a customer who is an operator of the self-register device 1 in the present embodiment. A touch panel is stacked on the surface of the display unit 13. When the barcode is normally read by the scanner unit 17, the speaker unit 15 emits a sound effect to notify that effect.

  The receipt printing unit 16 has a printing function for printing details after shopping. The receipt printing unit 16 prints the details of the purchased product on a predetermined receipt sheet in accordance with an instruction from the CPU 10. The receipt printing unit 16 may perform printing by using ink, or may perform printing by a method that does not use ink, such as thermal paper.

  The barcode scanner 17 reads a barcode attached to a product. When the barcode scanner 17 reads the barcode, it decodes the read data and transmits it to the CPU 10.

  The electronic money reader / writer 18 reads the balance amount from the electronic money recording medium located at a short distance (communication possible distance). The electronic money reader / writer 18 writes the balance amount newly calculated by the CPU 10 to the electronic money recording medium. The electronic money recording medium is an IC card or a mobile phone terminal having an IC chip for storing balance amount data as electronic money. The communication unit 19 communicates with the management device 3. The camera connection unit 20 communicates with the camera 2.

  The detection sensor 21 is, for example, a photoelectric sensor. Specifically, the detection sensor 21 includes a light projecting unit and a light receiving unit, emits light such as visible light or infrared light as signal light from the light projecting unit to the light receiving unit, and changes in the amount of light blocked by the object. Is detected by the light receiving unit, and it is detected whether or not the object has passed through the detection range. The detection sensor 21 may be a reflective photoelectric sensor that detects light reflected by an object and detects whether the object has passed through a detection range.

  In the present embodiment, the barcode scanner 17 is fixed to a counter table on which the self-register device 1 is placed. A detection sensor 21 is installed in the vicinity of the barcode scanner 17. Specifically, when the purchased product is moved to a range where the barcode scanner 17 can read the barcode, the detection sensor 21 is installed at a position where the purchased product can be detected. Thereby, the detection sensor 21 can detect an operation in which the product approaches the barcode scanner 17, that is, an operation of registering the purchased product. In FIG. 2, a set of detection sensors 21 is arranged next to the barcode scanner 17. However, a plurality of sets of detection sensors 21 may be arranged next to the barcode scanner 17. The detection sensor 21 may be arranged so as to surround the code scanner 17.

  For example, when the purchased product is brought close to the barcode scanner 17 but the surface of the barcode attached to the purchased product is not intentionally directed to the scanner light, or when the barcode is hidden with a finger or the like, the barcode is read. An operation that is not performed but seems to be a reading operation can be determined by the operation of the detection sensor 21 and the barcode scanner 17. Specifically, the detection sensor 21 detects the purchased product itself or the hand of the operator, but when the barcode scanner 17 does not read the barcode, the barcode is not actually read, but it is separated. It is possible to discriminate an operation that seems to be a reading operation from a store clerk or the like at a certain position.

  Next, the product file stored in the hard disk unit 11 in the present embodiment will be described with reference to FIG. The product file is data in which a product name and a price are associated with each product code. The product file may store information other than the product name and price.

  FIG. 4 is a schematic diagram showing the data structure of the product file in this embodiment. This product file has attributes of a product code, a product name, and a price. The product code is a number that uniquely determines the product. The product name is the name of the product. The price is the price of the product. In the illustrated example, the product name of the product with the product code “111111” is “AAA” and the price is “100” (line 301). The product name of the product with the product code “111112” is “BBB”, and the price is “200” (line 302). Other product codes are as illustrated.

  Next, registration data for storing registered data in one transaction stored in the RAM 12 in the present embodiment will be described with reference to FIG. The registration data is data registered during one transaction as described above. When a “shopping start” key displayed on the display unit 13 described later is pressed, “1” is added to the previous transaction No. A new transaction number is generated, and thereafter, a product code of a product registered during the transaction, date / time data read from the clock unit 22, detection data, data associated with the number, etc. are sequentially stored. Go.

  As the product code, the product code read by the barcode scanner 17 is stored, and when the product code is read by the barcode scanner 17, 1 is automatically stored. Further, when the number is input with a numeric key (not shown), the input number is stored. The date and time data stores the date and time read from the clock unit 22 when “1” is set in the detection data. Normally, when a barcode attached to a product is held over at the time of product registration, the detection sensor 21 detects the barcode almost at the same time, so that the date and time data can be regarded as the date and time when the barcode is read.

  The detection data is data indicating whether or not the detection sensor 21 has detected an operation for registering a purchased product. When the act of registering the purchased product is detected, “1” is set in the detection data.

  In the illustrated example, the transaction number is associated with “0001”, and product codes “111111” to “111115” are registered. For the product code “111111”, the detection data is “1”. , Information indicating that the number is “1” and the date and time data is “200807011111” (meaning that the detection sensor 21 detected at 12:11 on July 1, 2008) is stored (line 401). For the product code “111112”, information that the detection data is “1”, the number is “1”, and the date / time data is “200807011211” is stored (line 402). Lines 403 to 405 are as illustrated. Note that the row 406 stores only detection data and date / time data. This indicates that although the detection sensor 21 has detected a product, the barcode scanner 17 has not read the barcode.

  When a transaction closing operation is instructed, such as when an accounting key described later is pressed, the total amount is calculated based on the registered data stored in the RAM 12, and the change amount is calculated from the deposit amount. Check out. When the change amount is calculated, the registration data stored in the RAM 12 is transferred to a purchase record file stored in the hard disk unit 11 described later, and the registration data is stored in the hard disk unit 11 and then stored in the RAM 12. Information other than the transaction No. is cleared from the registered data. When the next “shopping” key is pressed, “1” is added to the transaction number.

  Next, a purchase record file stored in the hard disk unit 11 in the present embodiment will be described with reference to FIG. The purchase record file is a file that permanently stores the information registered in the purchase product registration process. For each transaction No, the product code, the date / time data when the detection data is set, the detection data, the number, Remember. Further, the total transaction amount, the deposit amount, and the change amount may be stored together.

  In the illustrated example, information of transaction numbers “0001” to “0003” is stored. For example, for the transaction No. “0001”, the information shown in the rows 501 to 506 is stored. Other transaction numbers are as illustrated.

  For example, in the purchased product registration process specified by transaction No. “0001”, product codes “111111” to “111115” are registered, and the date and time data is “111111”. “20080701211”, information that the detection data is “1” and the number is “1” is stored (row 501). For the product code “111112”, the date / time data “200807011111”, the detection data “1”, and the number “1” are stored (line 502). The other rows are as illustrated. The row 506 stores only detection data and date / time data. This indicates that although the detection sensor 21 has detected a product, the barcode scanner 17 has not read the barcode.

  Next, an image file stored in the storage unit of the management apparatus 3 in this embodiment will be described with reference to FIG. This image file has attributes of image data, start date and time, and end date and time for each transaction No. The image data is image data obtained by capturing an operation of the purchased product registration process. The start date and time indicates the date and time when image capturing is started. The end date and time indicates the date and time when the image capturing is ended. Note that the timing at which the camera 2 starts and ends the imaging will be described later.

  In the example shown in the figure, the image data obtained by capturing the operation of the purchase merchandise registration process specified by the transaction No. “0001” is “XXXXXX.mpg”, and the start date and time is “2008.07.01.12:10. The end date and time is “2008.07.01.12:14” (line 601). The image data obtained by capturing the operation of the purchase merchandise registration process specified by the other transaction No, the start date and time, and the end date and time are as illustrated.

  Next, the procedure of the purchased product registration process in the first embodiment will be described with reference to FIG. FIG. 8 is a flowchart showing the procedure of the purchased product registration process in the first embodiment.

(Step S101) When starting the purchase merchandise registration process, the customer places electronic money on the electronic money reader / writer 18 and presses the “shopping start” key 80 shown in FIG. The CPU 10 determines whether or not the “shopping start” key 80 displayed on the display unit 13 is pressed. If it is determined that the “shopping start” key 80 has been pressed (in the case of YES), the process proceeds to step S102; otherwise (in the case of NO), the process of step S101 is performed again.
FIG. 9 is a diagram showing a screen displayed on the display unit 13 in step S101. In the illustrated example, a “shopping start” key 80 is displayed in the center of the screen.

  (Step S <b> 102) The CPU 10 transmits an imaging start signal to the camera 2 via the camera connection unit 20. Then, the camera 2 starts imaging in a range where the reading operation by the barcode scanner 17 can be understood, and transmits the captured image data to the storage unit of the management apparatus 3 via the network. The management device 3 stores (records) the transmitted image data in the storage unit. During recording by the camera 2, the image data may be stored in the storage unit of the camera 2, and the image data may be transmitted to the storage unit of the management device 3 when the imaging is finished. Thereafter, the process proceeds to step S103.

  (Step S103) The CPU 10 increments the transaction number of the registered data stored in the RAM 12 that stores the data registered during one transaction by one. Further, the CPU 10 reads the balance of the electronic money placed on the electronic money reader / writer 18 in step S101 and causes the display unit 13 to display the balance. Thereafter, the process proceeds to step S104.

  (Step S104) The customer performs an operation for causing the barcode scanner 17 to read the barcode attached to the purchased product, whereby the detection sensor 21 detects the part of the product and performs the reading operation. Is detected, and detection data “1” is output. The CPU 10 stores “1” in the detection data column of the first line of the registration data. Thereafter, the process proceeds to step S105.

  FIG. 10 is a diagram showing a screen displayed on the display unit 13 in step S104. In the example shown in the drawing, a character “Please bring the barcode closer” 90 is displayed to instruct the customer to bring the barcode closer to the barcode reader 17.

  (Step S105) The CPU 10 determines whether or not the barcode scanner 17 has read the barcode in step S104. If it is determined that the barcode scanner 17 has read the barcode (in the case of YES), the process proceeds to step S106. Otherwise (in the case of NO), the process proceeds to step S107.

  (Step S106) The barcode scanner 17 decodes the barcode data read in step S104 into a product code. Then, the CPU 10 stores the product code decoded by the barcode scanner 17 in the product code column of the same row as the row in which the detection data is stored in step S104.

  And CPU10 acquires the price of the goods linked | related with the goods code memorize | stored in registration data at step S106 from the goods file memorize | stored in the hard disk part 11, accumulates and adds to the transaction total amount of registration data, and a display part 13 displays the total transaction amount. Thereafter, the process proceeds to step S107.

  FIG. 11 is a diagram showing a screen displayed on the display unit 13. In the example shown in the figure, the product name and price corresponding to the product code stored in the registration data are displayed on the left side of the screen (reference numeral 1001). In addition, the total number of registration data stored is displayed in the upper right corner of the screen as a purchase point (reference numeral 1002). In addition, the total price of the products corresponding to the product code stored in the registration data is displayed as a subtotal and total on the right side of the screen (reference numeral 1003). Also, the balance of electronic money is displayed at the lower right of the screen (reference numeral 1004). An “account” key 1005 is displayed at the lower left of the screen.

  (Step S107) The CPU 10 determines whether a reading operation has been detected. That is, it is determined whether or not a registration operation for the next product has been performed. If it is determined that the registration operation for the next product has been performed (in the case of YES), the process returns to step S105, and otherwise (in the case of NO), the process proceeds to step S108. When the next reading operation is detected, “1” is stored in the detection data in the next row of the registration data stored in the RAM 12, and if the barcode is read in step S105, that row is handled. The read product code is stored in the product code column.

  (Step S108) When the customer ends the purchased product registration process, the customer presses the “account” key displayed on the display unit 13. The CPU 10 determines whether or not the “account” key displayed on the display unit 13 has been pressed. If it is determined that the “account” key has been pressed (in the case of YES), the process proceeds to step S109; otherwise (in the case of NO), the process returns to step S107.

  (Step S109) The CPU 10 subtracts the transaction total amount stored in the registration data from the balance of electronic money read in step S103, and calculates the balance of electronic money after the settlement process. Further, the CPU 10 writes the calculated balance of electronic money to the electronic money placed in step S101 via the electronic money reader / writer 18 and ends the settlement. Then, it progresses to step S110.

  FIG. 12 is a diagram showing a screen displayed on the display unit 13 in step S109. In the example shown in the drawing, the total number of registration data stored is displayed as the number of purchases in the upper left of the screen (reference numeral 1101), and the total price of the product corresponding to the product code stored in the registration data is displayed as a subtotal and total as (Reference numeral 1102). The balance of electronic money before the settlement process is displayed on the upper left of the screen (reference numeral 1103), and the total price of the commodity corresponding to the commodity code stored in the registration data is displayed on the right of the screen as the transaction amount (reference numeral 1104). Furthermore, the balance of the electronic money after the settlement process is displayed at the lower left of the screen (reference numeral 1105).

  (Step S110) The CPU 10 shifts the registration data stored in the RAM 12 to a purchase record file stored in the hard disk unit 11. Subsequently, the CPU 10 erases data other than the transaction number in the registration data stored in the RAM 12. Then, it progresses to step S111.

  (Step S <b> 111) The CPU 10 transmits an imaging stop signal to the camera 2 via the camera connection unit 20, whereby the camera 2 stops imaging, and image recording (recording) in the management device 3 is stopped. At this time, the transaction No. stored in the registration data is transmitted to the management device 3, and the date / time data transmitted in Step S102 and the date / time data transmitted in Step S111 are stored in association with each other. The command is transmitted to the management device 3. Thereafter, the process ends.

  In addition, by performing a predetermined operation at the end of the business day, the purchase result file stored in the hard disk unit 11 of the self-register device 1 is transmitted to the management device 3.

  Next, a processing procedure for extracting image data obtained by capturing an operation with a high probability of fraud with the management apparatus 3 will be described with reference to FIG. FIG. 13 is a flowchart showing a procedure of extraction processing of image data obtained by imaging an operation with a high probability of fraud in this embodiment.

  (Step S201) When starting extraction of imaging data including an operation with a high probability of fraud, the operation mode of the management device 3 is changed to the extraction mode. The extraction work may be performed after the end of the business day. Thereafter, the process proceeds to step S202. As a method for changing to the extraction mode, for example, an “extraction mode” key displayed on the display unit of the management apparatus 3 is pressed.

  (Step S202) The CPU of the management device 3 searches for a purchase record file stored in the storage unit of the management device 3, and there is a transaction in which there is a row in which the detection data is stored but the product code is not stored. Determine whether or not. If it is determined that there is a row in which the detection data is stored and the product code is not stored, the process proceeds to step S203, and otherwise the process ends.

  (Step S203) The CPU of the management device 3 acquires the transaction No. associated with the line in which the detection data is stored in Step S202 and it is determined that the product code is not stored from the purchase record file. Thereafter, the process proceeds to step S204.

  (Step S204) The CPU of the management device 3 stores the product code, the detection data, the number, the total transaction amount, the deposit amount, and the product code stored in association with the transaction No acquired in Step S203 from the purchase record file. Get the change amount. Thereafter, the process proceeds to step S205.

  (Step S205) The CPU of the management device 3 obtains the image data, the start date and time, and the end date and time stored in association with the transaction number acquired in step S203 from the image file stored in the storage unit of the management device 3. get. Thereafter, the process proceeds to step S206.

  (Step S206) The CPU of the management device 3 stores the transaction No. acquired in Step S202, the item name in the item file corresponding to the item code acquired in Step S204, the detection data, the number, the total transaction amount, and the custody. The amount, change amount, start date / time, and end date / time are displayed on the right side of the display unit of the management apparatus 3, and the image data acquired in step S205 is displayed on the left side of the display unit of the management apparatus 3. Note that a reproduction key may be provided on the display unit, and the image data may be reproduced by pressing this key.

  FIG. 14 is a diagram showing a screen displayed on the display unit 13 in step S206. In the illustrated example, the start date and time and the end date and time are displayed at the top of the screen (reference numeral 1301). Moreover, transaction No. is displayed on the upper right of the screen (reference numeral 1302). An image based on the image data is displayed on the left side of the screen (reference numeral 1303). In addition, the product name associated with the product code is displayed in the center of the screen (reference numeral 1304). Further, a status based on the detected data is displayed on the right side of the product name (reference numeral 1305). In the example shown in the figure, the status “OK” is displayed for the detection data in the row in which the product code and the detection data are stored. Further, the status “NG” is displayed for the detection data in the row in which the product code is not stored and the detection data is stored. That is, in this transaction, since there is a suspicion of fraud in the registration operation after the product “EEE”, it is possible to confirm whether or not there is fraud by gazing at the image of that part.

  In addition, the number of products registered is displayed on the right side of the status (reference numeral 1306), the deposit amount (reference numeral 1307), the total transaction amount (reference numeral 1308), and the change amount (reference numeral 1309) are displayed. You can also check the settlement amount for the transaction.

  As described above, according to the present embodiment, an operation that seems to be a barcode reading operation is detected by the processing in steps S101 to S111, and the barcode is actually read by the operation. In addition, barcode information can be stored together. Further, image data obtained by imaging operations from the start to the end of the purchased product process can be stored in association with a transaction number for identifying the purchased product process.

  Further, by the processing in steps S201 to S206, image data obtained by capturing an operation in which the barcode is not actually read although the operation that seems to be performed is performed. Can be displayed on the display unit 13. Thereby, it is possible to efficiently confirm image data obtained by imaging an operation with a high probability of fraud.

(Second Embodiment)
Next, a second embodiment of the present invention will be described with reference to the drawings. FIG. 15 is a diagram showing the appearance of the self-register device in the present embodiment. FIG. 16 is a diagram showing an electrical block diagram of the self-register device 6 in the present embodiment.

  The scale unit 651 includes a weight sensor, and detects that a product or the like has been put in a shopping bag hung on a shopping bag hook 654 installed on the top of the scale unit 651. Thereby, the scale part 151 can detect operation which moves goods to the place where the registered goods are located.

  The difference between the second embodiment and the first embodiment is that, in the first embodiment, the bar code scanner 17 is a detection sensor 21 that performs detection at the same time as a bar code scanner operation as a detection unit. However, in the second embodiment, it is provided under the shopping bag hook 654 on the downstream side of the barcode scanner 67 that performs the reading operation, on which the shopping bag into which the product is inserted after the product registration is hung. The scale part 651 was used as a detection sensor.

  That is, when the weight value output from the scale unit 651 increases, the registered product is put into the shopping bag if the registration operation is normal, so that the product reading is performed as in the first embodiment. It can be presumed that the operation is also performed, and the product code read by the barcode scanner 67 and the detection data in this product have a paired relationship, which is the same as in the first embodiment.

  That is, in the first embodiment, when “1” is set in the detection data column of the predetermined line in the registration data in the RAM 12 of the self-register device 1, it is read in the product code column of this line. Although the product code is stored almost simultaneously, in the second embodiment, the product barcode is first read by the vertical barcode scanner 67 shown in FIG. When the product code is stored in the product code field of the product, and then the product is placed in a shopping bag into which the product is inserted after product registration, detection data is output, and “1” is displayed in the detection data column of the corresponding row. Remembered. That is, only the timing at which the detection data is stored is different, and the product code read by the barcode scanner 67 and the detection data in this product have a paired relationship as in the first embodiment. is there.

  In addition, there is an increase in the weight value in the scale unit 651 corresponding to the product code in the registration data stored in the RAM 62, and when it is detected, the detection data is set to “1”. The point of shifting to a purchase record file later is the same as in the first embodiment. And when extracting in extraction mode, it is the same as 1st Embodiment also about the point which extracts operation | movement with operation which the detection data is "1" but the corresponding product code is not memorize | stored. is there.

  Further, when the product code of the next product is read after the increase in the weight value is detected by the scale unit 651, it is determined that another product has been registered, and the registration data in the RAM 62 reads out to the next line. The product code for the sold product is stored.

  The timing for transmitting the imaging start signal and the imaging stop signal to the camera 2 is also determined by pressing the “registration start” key (“shopping start” key in the first embodiment) displayed on the first liquid crystal touch panel 652. It is the same as in the first embodiment in that the imaging end signal is transmitted by transmitting the imaging start signal and pressing the “registration end” key (the “accounting key” in the first embodiment).

  The image data captured by the camera 2 is also stored (recorded) in the storage unit of the management device 3 in the same manner as in the first embodiment.

  In addition, in 2nd Embodiment, although operation which registers purchase goods was detected using the scale part 151 provided with the weight sensor, you may detect operation which registers purchase goods using a photoelectric sensor. A specific example will be described with reference to FIG. FIG. 17 is a view showing a shopping bag hook 154 provided with a photoelectric sensor.

  In the example shown in the drawing, photoelectric sensors 1901 to 1903 are arranged so as to detect products placed in the shopping bag at the upper part of the shopping bag hook 654. The photoelectric sensors 1901 to 1903 are the same photoelectric sensors as the detection sensor 21 of the first embodiment. The photoelectric sensors 1901 to 1903 detect that a product or the like is put in the shopping bag 1904 hung on the shopping bag hook 654. Thereby, the photoelectric sensors 1901 to 1903 can detect the operation of moving the product.

  In the second embodiment, the scale unit 651 is disposed downstream of the barcode scanner 67 (on the left side of the barcode scanner 67 in FIG. 15), but the scale unit 651 is disposed upstream of the barcode scanner 67 (FIG. 15). Then, it may be arranged on the right side of the barcode scanner 67. In this arrangement, the scale unit 651 detects that the product has been put out from the shopping basket placed before the purchase product is registered. Thereby, the scale part 651 can detect the operation of moving the product for product registration, that is, the operation of registering the purchased product.

  As described above, the embodiments of the present invention have been described in detail with reference to the drawings. However, the specific configuration is not limited to the above, and various design changes and the like can be made without departing from the scope of the present invention. Is possible.

  For example, in the first embodiment and the second embodiment, when moving the registration data stored in the RAMs 12 and 62 to the purchase record file stored in the hard disk of the management device 3, the CPUs 10 and 60 If it is determined that there is a row in which the detection data is stored and the product code is not stored, a lamp indicating an abnormality may be lit to notify the terminal held by the store clerk that there is an abnormality.

  Further, although the image data and the registration data are displayed on the display unit of the management device 3, only the image data of the extracted transaction No. may be displayed. In addition, the extracted image data and registration data are displayed on the display unit 13 of the self-register device 1 (in the second embodiment, the first liquid crystal touch panel 652 or the second liquid crystal touch panel 658 of the self-register device 6). Alternatively, only the image data may be displayed.

  In the above-described embodiment, the detection information and the product code of the read product are stored in pairs. However, the product code is read correctly, not the product code itself. Information and detection information may be stored in pairs.

  In both cases of the first embodiment and the second embodiment, the product registration is performed when the product detected by the detection unit is read or when the product is not read. Image data of processing operation is stored, and image data when the product is not read is extracted from the stored image data, but the product detected by the detection unit is not read Even if only the image of the case or only the image data including before and after is stored in the storage unit, it is included in the present invention as being extracted in advance.

  In other words, the image data to be stored may be stored only when the product is not read, or when the product is read, in addition to the case where the product is not read. You may make it do.

  And when storing the image data detected only by the detection unit but not reading the product, for example, the image of one transaction registration processing operation is continuously temporarily stored in the temporary storage area of the camera, At the end of one transaction, for example, if it is determined that the product code is not associated with the detection information, the time when the product is registered is read, and only the image data stored in the temporary storage area of the camera at that time Alternatively, image data including a time before and after a predetermined time may be stored in the storage unit of the management device. The image data temporarily stored in the camera may be cleared or overwritten when the next registration is started.

As described above, by storing image data that has been detected by at least the detection unit but is not read, the image having an illegal probability can be efficiently extracted.
The storage of the image data is not limited to every transaction, and may be every predetermined time such as every minute.
In the present embodiment, the POS system in which the customer himself / herself registers the product has been described as an example. However, a POS system in which the store clerk registers the product may be used.
