It is an example of the packaged goods storage part in which goods weight was stored.

  The barcode related table of FIG. 5 stores a single item product barcode 300a which is identification information of a single item product 300 and a packaged product barcode 302a which is identification information of a packaged product 302 including the single item product 300 in association with each other. This is an example of the identification information related storage unit.

  Next, the functional configuration of the self-checkout apparatus 10 according to the first embodiment will be described. FIG. 7 is a diagram showing an example of a functional configuration of the self-checkout apparatus 10 according to the first embodiment.

  The CPU 101 of the self-checkout apparatus 10 includes a main control unit 401, an identification information reading unit 402, a commodity weighing unit 403, a packaged commodity judgment unit 404, a single commodity commodity judgment unit 405, a commodity price acquisition unit 406, and a weight. A determination unit 407, a packaged product identification information acquisition unit 408, a packaged product weight acquisition unit 409, a packaged product weight determination unit 410, an automatic cancellation unit 411, and a guide unit 412 are included at least.

  The main control unit 401 controls the entire self-checkout apparatus 10 by the CPU 101 executing the automatic settlement processing program.

  The identification information reading unit 402 controls the barcode scanner 16 to read a barcode of a product. The identification information reading unit 402 stores the read barcode in the product information storage area 510.

  The commodity weighing unit 403 controls the weighing device 20 to weigh the commodity weight of the commodity whose barcode is read by the identification information reading unit 402. The commodity weighing unit 403 stores the weighed commodity weight in the commodity information storage area 510.

  The packaged product determining unit 404 determines whether the barcode read by the identification information reading unit 402 is included in the barcode stored in the packaged product table 502. Specifically, the packaged product determination unit 404 refers to the packaged product table 502 in FIG. 4B, and the barcode read by the identification information reading unit 402 becomes the packaged product barcode of the packaged product table 502. It is determined whether it is included.

  When it is determined that the read barcode is not included in the packaged product barcode stored in the packaged product table 502, the single product commodity determining unit 405 is stored in the single item commodity table 501. It is determined whether the bar code is included. Specifically, the single-item product determination unit 405 refers to the single-item product table 501 in FIG. 4A, and the barcode read by the identification information reading unit 402 corresponds to the single-item product barcode of the single-item product table 501. It is determined whether it is included.

  The commodity amount acquisition unit 406 acquires the commodity amount corresponding to the barcode stored in the single item commodity table 501 based on the barcode read by the identification information reading unit 402. Specifically, the commodity price acquisition unit 406 refers to the single item commodity table 501 of FIG. 4A, and the commodity price corresponding to the same single item commodity barcode as the barcode read by the identification information reading unit 402 get. The commodity price acquisition unit 406 stores the acquired commodity price in the commodity information storage area 510.

  If it is determined by the single item commodity determination unit 405 that the weight determination unit 407 is included in the single item commodity barcode stored in the single item commodity table 501, the commodity weight weighed by the commodity weighing unit 403 is a single item commodity. It is determined whether or not the product weight corresponding to the single-item product barcode stored in the product table 501 matches.

  Specifically, the weight determination unit 407 refers to the single item product table 501 in FIG. 4A, and acquires the product weight corresponding to the single item product barcode that is the same as the barcode read by the identification information reading unit 402. Do. Then, the weight determination unit 407 determines whether the product weight measured by the product measurement unit 403 matches the product weight acquired from the single item product table 501.

  When it is determined by the weight determination unit 407 that the packaged product identification information acquisition unit 408 does not match the product weight corresponding to the single item product barcode stored in the single item product table 501, the identification information reading unit 402 reads it. The packaged product barcode of the packaged product including the acquired barcode is acquired from the barcode related table 503.

  Specifically, the packaged product identification information acquisition unit 408 refers to the barcode related table 503 of FIG. 5 and packages corresponding to the same single item product barcode as the barcode read by the identification information reading unit 402. Get product barcodes.

  For example, when the barcode read by the identification information reading unit 402 is "00001003", referring to the barcode related table 503 in FIG. 5, the single item commodity barcode "00001003" which is the same as this barcode is associated. Packaged product barcodes are of two types "90001002" and "90001004". In this case, the packaged product identification information acquisition unit 408 acquires two packaged product barcodes “90001002” and “9000104”.

  The packaged product weight acquisition unit 409 acquires the product weight corresponding to the packaged product barcode of the packaged product acquired by the packaged product identification information acquisition unit 408 from the packaged product table 502.

  For example, when the packaged product barcode acquired by the packaged product identification information acquisition unit 408 is two types of "90001002" and "90001004", referring to the packaged product table 502 in FIG. The product weights corresponding to the barcodes "90001002" and "90001004" are two types of "1760 g" and "1520 g". In this case, the packaged product weight obtaining unit 409 obtains two product weights “1760 g” and “1520 g”.

  The packaged commodity weight determination unit 410 determines whether the commodity weight acquired by the packaged commodity weight acquisition unit 409 matches the commodity weight measured by the commodity measurement unit 403 or not.

  When the product weight acquired by the packaged product weight acquiring unit 409 includes plural types of product weights, the packaged product weight determining unit 410 acquires the product weight measured by the product measuring unit 403 by the packaged product weight acquiring unit 409. It is determined whether or not any one of a plurality of types of product weights is matched.

  For example, if the product weight acquired by the packaged product weight acquisition unit 409 is two types of “1760 g” and “1520 g”, the packaged product weight determination unit 410 determines that the product weight measured by the product weighing unit 403 is It is determined whether or not any one of the product weights “1760 g” and “1520 g” acquired by the packaged product weight acquisition unit 409 matches.

  The automatic cancellation unit 411 is read by the identification information reading unit 402 when the weight determination unit 407 determines that the weights do not match and when the packaged product weight determination unit 410 determines that the product weights match. The bar code and the commodity price acquired by the commodity price acquisition unit 406 are deleted.

  Specifically, the product weight measured by the product weighing unit 403 and the product weight obtained from the single item product table 501 do not match, and the product weight obtained by the packaged product weight obtaining unit 409, and the product weighing unit If the measured product weight 403 matches the product weight, the automatic cancellation unit 411 deletes the barcode, product weight, product category, and product price stored in the product information storage area 510. As a result, the erroneous scan performed by the customer can be automatically canceled, and even if the identification information corresponding to the single item is read despite the identification information corresponding to the packaged item being present, It becomes possible to continue the settlement processing of goods without intervention of a salesclerk.

Furthermore, when the automatic cancellation unit 411 erases the commodity price or the bar code, the guiding unit 412 performs guidance for prompting the bar code of the product to be read again by the identification information reading unit 402.
Specifically, the guide unit 412 displays on the LCD 13 a warning message indicating that the barcode attached to the exterior of the packaged product is to be read again, or the voice output device 24 displays the barcode attached to the exterior of the packaged product. Control to display a reminder message to read again and As a result, the customer can perform settlement processing of the product without calling a store clerk.

  Next, the flow of the automatic settlement process of the first embodiment will be described. 8A and 8B are flowcharts showing an example of the automatic settlement process of the first embodiment. The automatic settlement process is started when the customer presses a transaction start button and the main control unit 401 receives an instruction to start the settlement process.

  First, the main control unit 401 controls the LCD 13 to display a message prompting the bar code scanner 16 to read the bar code (step S101), and the identification information reading unit 402 makes the setting of the bar code scanner 16 effective. (Step S102).

  The identification information reading unit 402 stands by until the barcode is read, and stores the barcode read by the barcode scanner 16 in the product information storage area 510 when the barcode scanner 16 reads the barcode (step S103). (Step S104). Then, the identification information reading unit 402 invalidates the setting of the barcode scanner 16 in order to prevent double reading of the barcode data (step S105).

  The commodity weighing unit 403 weighs the commodity weight by the weighing device 20 (step S106), and stores the weighed commodity weight in the commodity information storage area 510 (step S107).

  The packaged product determining unit 404 refers to the packaged product table 502 in FIG. 4B and determines whether the barcode stored in the product information storage area 510 is the barcode of the packaged product (step S108). In this process, the packaged product determining unit 404 determines whether the barcode stored in the product information storage area 510 is included in the packaged product barcode stored in the packaged product table 502. That is, it is determined whether the barcode read by the barcode scanner 16 is the packaged commodity barcode attached to the packaged commodity or the other barcode (for example, a single commodity barcode).

  When the read barcode is included in the packaged product barcode stored in the packaged product table 502 (YES in step S109), the product amount acquisition unit 406 performs the packaged product table 502 in FIG. 4B. The commodity weight and the commodity price are acquired from the bar code stored in the commodity information storage area 510 with reference to (step S110). In this process, the commodity amount acquisition unit 406 acquires the commodity weight and the commodity amount corresponding to the same packaged commodity barcode as the barcode stored in the commodity information storage area 510. That is, when it is included in the packaged product barcode stored in the packaged product table 502, the product read by the barcode scanner 16 is determined to be a packaged product, and the product weight and the product amount corresponding to the packaged product. Is acquired.

  The main control unit 401 stores the packaged item as the packaged item in the item category of the item information storage area 510 (step S111). That is, the barcode read by the barcode scanner 16 in step S103 is determined to be the packaged product barcode attached to the packaged product, and the character of the packaged product is stored in the product category as the determination mark. When this process ends, the process proceeds to step S117.

  On the other hand, when the read barcode is not included in the packaged product barcode stored in the packaged product table 502 (NO in step S109), the single-item commodity determination unit 405 performs the process shown in FIG. With reference to the single item product table 501, it is determined whether the barcode stored in the product information storage area 510 is the barcode of the single item product (step S112). In this process, the packaged product determination unit 404 determines whether the barcode stored in the product information storage area 510 is included in the single product barcode stored in the single product table 501.

  When the read barcode is included in the single-item product barcode stored in the single-item product table 501 (YES in step S113), the product amount acquisition unit 406 performs the single-item product table 501 in FIG. The corresponding commodity weight and commodity price are acquired from the bar code stored in the commodity information storage area 510 (step S114). In this process, the commodity amount acquisition unit 406 acquires the commodity weight and the commodity weight corresponding to the single item commodity barcode that is the same as the barcode stored in the commodity information storage area 510. That is, when it is included in the single item commodity barcode stored in the single item commodity table 501, the commodity read by the barcode scanner 16 is determined to be a single item commodity, and the commodity weight and commodity price corresponding to the single commodity item. Is acquired.

  The main control unit 401 stores the item category of the item information storage area 510 as a single item item (step S115). That is, the barcode read by the barcode scanner 16 in step S103 is determined to be a single item commodity barcode attached to a single item commodity, and the character of the single item commodity is stored in the commodity category as the determination mark. When this process ends, the process proceeds to step S117.

  On the other hand, when it is not included in the single item product barcode stored in the single item product table 501 (NO in step S113), the main control unit 401 accepts cancellation processing by the store clerk for erroneous scan (step S116). ). When the clerk cancels the process, the automatic settlement process is resumed.

  In step S117, the main control unit 401 stores the commodity price acquired by the commodity price acquisition unit 406 in step S110 or step S114 in the commodity information storage area 510.

  The weight determination unit 407 determines whether the product weight stored in the product information storage area 510 matches the product weight acquired in step S110 or step S114 (step S118).

  In this process, when going through step S110, it is determined whether the product weight measured by the weighing device 20 matches the product weight determined from the packaged product table 502 that is determined to be a packaged product. It is judged. Further, when going through step S114, it is determined whether the product weight measured by the weighing device 20 and the product weight acquired from the single product table 501 determined to be a single product are identical. Ru.

  If the item weights do not match (NO in step S119), the main control unit 401 determines whether the item category stored in the item information storage area 510 is a single item item (step S120). If the item category stored in the item information storage area 510 is not a single item item (NO in step S120), the process returns to step S116, and the main control unit 401 receives cancellation processing by the store clerk for erroneous scanning.

  On the other hand, if the product category stored in the product information storage area 510 is a single item product (YES in step S120), the packaged product identification information acquiring unit 408 refers to the barcode related table 503 and stores the product information. The packaged product barcode including the barcode stored in the area 510 is acquired (step S121). When there are a plurality of packaged product barcodes including the barcode stored in the product information storage area 510, the packaged product identification information acquiring unit 408 acquires a plurality of packaged product barcodes.

  The packaged product weight acquisition unit 409 refers to the packaged product table 502, and acquires the product weight from the packaged product barcode acquired by the packaged product identification information acquisition unit 408 in step S121 (step S122). When there are a plurality of packaged product barcodes acquired by the packaged product identification information acquisition unit 408, the packaged product weight acquisition unit 409 acquires a plurality of product weights for each of the plurality of packaged product barcodes.

  The packaged product weight determination unit 410 determines whether any one of the product weight stored in the product information storage area 510 in step S107 and the product weight acquired by the packaged product weight acquisition unit 409 in step S122 matches. (Step S123). When there are a plurality of product weights acquired by the packaged product weight acquisition unit 409, the packaged product weight determination unit 410 matches any product weight among the plurality of product weights acquired by the packaged product weight acquisition unit 409. Determine if it is.

  If none of the product weights acquired by the packaged product weight acquisition unit 409 matches (NO in step S124), the process returns to step S116, and the main control unit 401 receives cancellation processing by the store clerk for an erroneous scan. .

  On the other hand, if the package product weight acquisition unit 409 matches any of the product weights acquired (YES in step S124), the automatic cancellation unit 411 stores the barcode stored in the product information storage area 510, The item weight, the item category, and the item amount are deleted (step S125). In this process, the barcode read by the barcode scanner 16, the product weight measured by the weighing device 20, the product category stored by the main control unit 401, and the product price acquired by the product price acquisition unit 406 are automatically canceled. It is erased by the unit 411.

  The identification information reading unit 402 validates the setting of the barcode scanner 16 that has been invalidated in step S105 (step S126).

  The guiding unit 412 executes control to display on the LCD 13 an alert message prompting re-reading of the packaged product barcode (step S127). Furthermore, the guiding unit 412 may execute control to output an audio of an alert message prompting re-reading of the packaged product barcode to the audio output device 24. Specifically, the guide unit 412, for example, "canceled because the barcode read in the previous step is a barcode of a single item product. Return the product to the shopping cart, read the barcode of the packaged product (packed product) A warning message “Please make another request” is displayed on the LCD 13. The guiding unit 412 can also add the commodity name of the commodity for which the bar code is to be read again by returning to the shopping basket and the alert message. In this case, the guiding unit 412 takes out the product name corresponding to the bar code erased by the automatic canceling unit 411 in step S125 from the single item product table 501 of FIG. 4A and adds it to the alert message. Further, the guide unit 412 can also add an image of a product taken by the camera scanner 16a at the time of reading a bar code to a warning message. Further, the guiding unit 412 may output the voice of the same alerting message to the voice output device 24. When this process ends, the process returns to step S103, and the bar code scanner 16 starts to read the bar code again.

  Returning to step S119, if the item weights match (YES in step S119), the main control unit 401 accumulates the item amount stored in the item information storage area 510 in the adjustment amount storage area 511 as a settlement amount. And store (step S128).

  The main control portion 401 determines whether or not the settlement button (not shown) displayed on the LCD 13 is pressed through the touch panel 14 (step S129). If the settlement button (not shown) is not pressed (NO in step S129), the main control unit 401 deletes the barcode, the product weight, the product category, and the product price stored in the product information storage area 510. (Step S130). When this process ends, the process returns to step S101, and the display of a message prompting the reading by the barcode scanner 16 is started again.

  On the other hand, when the settlement button is pressed (YES in step S129), the main control unit 401 performs the settlement process with the settlement amount stored in the settlement amount storage area 511 (step S131). In this process, after the item values of all the items to be purchased by the customer are stored, insertion of cash or a credit card is inserted. Thus, the settlement process is performed, and the change, the used credit card, and the receipt are discharged from the self checkout device 10. When the customer receives these and the transaction is over, the automatic settlement process is over.

  For example, the case where the barcode of the packaged product 302 of "6 bottles of beer" as shown in FIG. 3 is read by the self-checkout apparatus 10 will be described. In this case, the bar code 302a attached to the outer package 301 of the packaged product 302 must be read by the bar code scanner 16, but it is assumed that the customer erroneously reads the bar code 300a of the single item 300.

  In this case, the barcode of the single item commodity read by the identification information reading unit 402 is "00001000", and after reading the barcode, the commodity weight of the packaged commodity weighed by the commodity weighing unit 403 is "1320 g".

  The bar code "00001000" of the single item commodity read by the identification information reading unit 402 and the commodity weight "1320 g" weighed by the commodity weighing unit 403 are stored in the commodity information storage area 510 as shown in FIG. S104 and step S107) are performed.

  The packaged product determination unit 404 refers to the packaged product table 502 in FIG. 4B and determines whether the barcode "00001000" is included in the packaged product barcode (step S108). Since the barcode "00001000" is not included in the packaged product barcode, it is determined that the packaged product barcode is not included (NO in step S109).

  In this case, the single-item product determination unit 405 refers to the single-item product table 501 in FIG. 4A and determines whether the barcode "00001000" is included in the single-item product barcode (step S112). Since the barcode "00001000" is included in the single item commodity barcode, it is determined that the single item commodity barcode is included (YES in step S113).

  Thereafter, the commodity price acquisition unit 406 refers to the single item commodity table 501 of FIG. 4A, and the commodity weight “220 g” and the commodity price “130 yen” corresponding to the barcode “00001000” are acquired (step S114) . Then, “single item commodity” is stored in the commodity category of the commodity information storage area 510, and “130 yen” is stored in the commodity price (steps S115 and S117).

  As a result of determining whether the product weight “1320 g” stored in the product information storage area 510 matches the product weight “220 g” acquired from the single item product table 501 by the weight determination unit 407, the product weight is one. It is determined that it does not do (NO of step S119).

  The packaged product identification information acquisition unit 408 refers to the barcode related table 503 in FIG. 5 and acquires packaged product barcodes “90001000” and “90001004” including the barcode “00001000” stored in the product information storage area 510. (Step S121).

  In addition, the packaged product weight acquisition unit 409 refers to the packaged product table 502 in FIG. 4B and the product weights “1320 g” and “1520 g” corresponding to the acquired packaged product barcodes “90001000” and “90001004” It is acquired (step S122).

  The packaged product weight determination unit 410 determines whether the product weight “1320 g” stored in the product information storage area 510 matches the product weight “1320 g” or “1520 g” acquired by the packaged product weight acquisition unit 409 (see FIG. Step S123).

  It is determined that the product weight “1320 g” stored in the product information storage area 510 matches “1320 g” out of the product weights “1320 g” or “1520 g” acquired by the packaged product weight acquisition unit 409 (step S124 YES) In this case, the automatic cancellation unit 411 erases the bar code, the product weight, the product category, and the product price stored in the product information storage area 510 (step S125).

  As described above, according to the self-checkout apparatus 10 of the first embodiment, the single item product 300 is attached with the barcode 300 a as identification information of the single item product 300 and the exterior 301 of the packaged product 302. In each item, a barcode 302 a is attached as identification information of the packaged product 302 in which a plurality of single item products 300 are collected.

  When the barcode of the packaged product 302 is to be read by the self-checkout apparatus 10, the bar code 302a of the packaged product 302 has to be read by the barcode scanner 16; There is a possibility of reading 300a. In that case, an error occurs because the bar code 300a of the single item 300 read by the scanner does not match the weight of the item 300 corresponding to the single item 300 stored in the item table described later. In that case, it is necessary to call a store clerk in order to cancel a bar code that has been read by mistake. In addition, when the response of the cancellation operation of the store clerk is delayed, such as a busy time zone or nighttime, a queue (waiting time) of the customer is generated. Furthermore, when another customer is waiting for the self-checkout device 10, the waiting time for the other customer is also long. Therefore, in the first embodiment, even if identification information corresponding to a single item is read despite the presence of identification information corresponding to a packaged item, the above-described configuration allows the item to be continuously settled. Processing can continue.

Second Embodiment
In the second embodiment, the appearance configuration, the hardware configuration, the configuration of the product table, the configuration of the bar code related table, and the configuration of the product information storage area are the same as the self checkout device 10 of the first embodiment. Description is omitted because there is.

  FIG. 9 is a diagram showing an example of a functional configuration of the self-checkout apparatus 10 according to the second embodiment.

  The CPU 101 of the self-checkout apparatus 10 of the second embodiment is different in that a packaged merchandise price acquisition unit 601 is provided instead of the guide unit 412. Therefore, the main control unit 401, the identification information reading unit 402, the commodity measuring unit 403, the packaged commodity determination unit 404, the single item commodity determination unit 405, the commodity amount acquisition unit 406, the weight determination unit 407, the packaged commodity identification information acquisition unit 408, the packaging The commodity weight acquisition unit 409, the packaged commodity weight determination unit 410, and the automatic cancellation unit 411 will be omitted because their descriptions are the same as those of the first embodiment.

  The packaged product price acquisition unit 601 refers to the packaged product table 502 in FIG. 4B and acquires the product price from the matched product weight. The automatic settlement process of the second embodiment will be described for the process of acquiring the commodity price by the packaged commodity price acquisition unit 601.

  Next, the flow of the automatic settlement process of the second embodiment will be described. FIGS. 10A and 10B are flowcharts showing an example of the automatic settlement process of the second embodiment.

  The processes of steps S201 to S224 and steps S229 to S232 of the automatic settlement process of the second embodiment are the same as the processes of steps S101 to S124 and steps S128 to S131 of the automatic settlement process of the first embodiment. The description is omitted because it is similar.

  If any of the product weights obtained by the packaged product weight obtaining unit 409 matches (YES in step S224), the automatic cancellation unit 411 deletes the product amount stored in the product information storage area 510 (step S225).

  The packaged product price acquisition unit 601 refers to the packaged product table 502 in FIG. 4B and acquires the product price from the matched product weight. In this process, the packaged product price acquisition unit 601 acquires the product price of the product weight determined in step S224 that the product weights match (step S226).

  The main control unit 401 changes the product category of the product information storage area 510 into a packaged product and stores it (step S227). That is, although the barcode read by the barcode scanner 16 in step S203 is a single-item product barcode attached to a single-item product, it is considered to be that of a packaged product, and the packaged product Characters are stored. The main control unit 401 stores the commodity price acquired by the packaged commodity price acquisition unit 601 in step S226 in the commodity information storage area 510 (step S228). When this process ends, the process proceeds to step S229.

For example, it is determined that the product weight “1320 g” stored in the product information storage area 510 matches “1320 g” out of the product weights “1320 g” or “1520 g” acquired by the packaged product weight acquisition unit 409 (step The case where YES in S224 will be described.
In this case, the automatic cancellation unit 411 deletes the commodity price stored in the commodity information storage area 510 (step S225). Then, the packaged product price acquisition unit 601 refers to the packaged product table 502 and acquires the product price “760 yen” of the same product weight as the matched product weight “1320 g” (step S226).

  As described above, according to the self-checkout apparatus 10 of the second embodiment, when the barcode of the packaged product 302 is read by the self-checkout apparatus 10, the barcode 302a of the packaged product 302 is used as a bar. Although the code scanner 16 has to read it, the customer may mistakenly read the bar code 300 a of the single item 300. In that case, the processing of reading the barcode 300a of the single item by the barcode scanner 16 is regarded as the processing of reading the barcode 302a of the packaged item by the barcode scanner 16 and the settlement processing of the packaged product is continued without the sales clerk. You can continue.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various improvements and modifications can be made without departing from the scope of the present invention.
