 According to the first aspect of the present invention, when weight data is not set at the time of product registration, the weighing data calculated from the scale unit is set in relation to the product as the weight data of the product. Since the clerk does not need to set weight data in advance, the operability is improved and an excessive work load is not imposed on the store side.

 According to the invention of claim 2, it is possible to correctly account only the results purchased by the customer by preventing the purchase results registered by the store clerk from being added to the results data registered by the customer's operation. By using this function, the store clerk can set the weight data related to the product simply by registering the product, so it is much more effective than setting the weight data manually. Workability is improved.

 According to the invention of claim 3, even if the weight data is set for the product specified at the time of registering the product, it is possible to register the product based on the correct weight data even if the weight data is not set. Even if data is not set, an error is generated and the registration operation is not interrupted, so that smooth product registration is possible.

 According to the invention of claim 4, when the weight data is not set for the specified product, the calculated measurement data is set, so that the clerk does not need to set the weight data, so that the operability is improved. In addition, a self-scanning system by the customer can be realized without imposing an excessive work burden on the store side. In that case, if the changes in the weight data before and after the product registration match, it can be regarded as correct product registration, so that even if weight data is not set, it is possible to register the product accurately.

 According to the inventions of claims 5 to 7, even when the weight of the normal product is set in relation to the product, for example, when the product is discounted only for a certain period, or the content is increased as a sale product For example, during the sale period, it is possible to determine whether or not the product registration is appropriate by invalidating the set weight data and matching the weight changes before and after product registration. Even when the content is increased, product registration can be performed without changing the set weight data. In addition, since the set weight data is valid during the sale period, whether or not the registration is appropriate is determined based on the set weight data and the weighing data from the scale unit.

 According to the eighth aspect of the present invention, there is an individual difference in the weight of one product, such as cabbage or fruit, which is not attached with a barcode and is specified by key input on the display unit or the operation unit. Product registration can be performed accurately by seeing the coincidence of weight changes before and after registration.

 According to the invention of claim 9, since the same product is weighed a plurality of times and is set in relation to the product weight data based on the plurality of weight provisional data, the weight data with no more weighing error is specified. It can be set to the product.

 According to the invention of claim 10, since it can be understood that the weight data set in relation to the product is data set and calculated from the scale unit attached to the POS register, for example, whether the weight data is correct or not is determined later. Even if there is an error in the weight, it is possible to easily determine that the scale portion has failed by knowing the origin of the weight data.

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is an overview configuration diagram showing an overview configuration of the self-scanning system according to the present embodiment. The self-scanning system according to this embodiment includes a product registration unit 1 and a product checkout unit 2.

 The product registration unit 1 includes a first liquid crystal touch panel 101, a key operation unit 102 such as a numeric key, a product number key, a discount key, a return key, and a confirmation key, and a scanner unit 103 that reads a barcode attached to the product. The first scale unit 104, the second scale unit 105, the product registration unit first display unit 106, the product registration unit second display unit 107, and the shopping bag for storing the products registered by the scanner unit 103 And a shopping bag hook 108 for hooking. The shopping bag hook 108 is detachably installed on the upper portion of the second scale portion 105.

 The product registration unit first scale unit 104 and the product registration unit second scale unit 105 are provided on the left and right sides of the first liquid crystal touch panel 101 and the scanner unit 103. The right side of FIG. 1 is a product registration unit first scale unit 104, and the left side of FIG. 1 is a product registration unit second scale unit 105. In the “clerk mode” in which the clerk registers and clears the merchandise, the merchandise registration unit first display unit 106 displays the merchandise name, the price, and the like on the clerk side. The product registration unit second display unit 107 displays the product name, the price, etc. on the customer side only during normal use when the customer brings the product purchased by the customer to the cash register and the store clerk registers the product.

 The product settlement unit 2 includes a cash register main body 20, a drawer 21, an automatic change machine 22, a sensor 23, and a call lamp 24. The cash register main body 20 includes a second liquid crystal touch panel 201, a key operation unit 202 such as a numeric key, a product number key, a discount key, and a return key, a receipt printer 203 that prints a receipt, and a product checkout unit first display unit 204. And a product settlement section second display section 205.

 The drawer 21 is a safe for storing spare banknotes, coins and other gift certificates and sales slips. Only in the clerk mode, when a specific key is pressed by the key operation of the cash register body 20, the solenoid is turned on and opened. The automatic change machine 22 has a coin slot 221, a coin outlet 222, a banknote slot 223, and a banknote outlet 224.

 The first liquid crystal touch panel 101 and the second liquid crystal touch panel 201 are display input devices capable of setting each mode and the like by touching while viewing the display. In addition, when the customer is in the “self mode” in which merchandise registration and settlement is performed by himself / herself, the key operation units 102 and 202 are covered with a cover so as not to be used by the customer. This is because when the key operation is performed by the customer, the customer searches for which key to press from a large number of keys, and the operation is not smooth.

 In addition, there is a possibility that the processing is confused by an incorrect key operation of the customer, or the customer makes an illegal input by pressing a discount key, for example. The customer performs all operations using only the first liquid crystal touch panel 101 and the second liquid crystal touch panel 201. In this embodiment, the product registration unit 1 and the product settlement unit 2 are installed in one place, but they are installed in different locations, and the product registration unit 1 only performs product registration. A receipt number for identifying one transaction may be printed and issued, and the customer may take the receipt and move to the place where the product settlement unit 2 is installed, and the store clerk may perform settlement.

 FIG. 2 is a block diagram showing an internal configuration of the self-scanning system shown in FIG. The CPU 300 is shared by both the product registration unit 1 and the product settlement unit 2, and controls each internal block of the product registration unit 1 and the product settlement unit 2 via the system bus 301. The ROM 302 stores an operation program for the CPU 300, and the RAM 303 temporarily stores files, setting data, and the like necessary for the CPU 300 to operate. The ROM 302 and the RAM 303 are also shared by both the product registration unit 1 and the product checkout unit 2.

 In addition, the internal components of the self-scanning system shown in FIG. 2 include a communication unit 304 for connecting to another register, first and second load cells 305 and 306, and first and second load cell controls. Sections 307 and 308, a merchandise registration section control section 309, a merchandise settlement section control section 310, and a serial communication section 311.

 Among these, the first and second load cells 305 and 306 are provided in the first and second weighing units 104 and 105, respectively, and measure the respective weights. The first and second load cells 305 and 306 are connected to the system bus 301 via the first and second load cell control units 307 and 308.

 The product registration unit control unit 309 controls the first liquid crystal touch panel 101 and the key operation unit 102. The product settlement unit control unit 310 controls the second liquid crystal touch panel 201 and the key operation unit 202. The product registration unit control unit 309 and the product settlement unit control unit 310 are each connected to the system bus 301. The automatic change machine 22 is connected to the system bus 301 via the serial communication unit 311.

 FIG. 3 is a RAM map showing the arrangement of data in the RAM 303 of the self-scanning system of this embodiment. The RAM map in FIG. 3 includes a work area A1, a product file A2, a first weight value A3, a second weight value A4, a weight change A5 of the first balance, and a weight of the second balance. The area includes a change amount A6, a first-time product data storage unit A7, and a second-time product data storage unit A8.

 The work area A1 is an area such as a register, and the first weight value A3 and the second weight value A4 are areas for storing the weight value for each balance and measuring the weight value variation. is there. The product file A2 is an area for storing product data such as product barcodes, product names, and prices. The data stored in the weight value A3 for the first scale and the weight value A4 for the second scale are stored when the weight value of each scale is stabilized when the product is weighed. The weight change amount A5 of the first balance and the weight change amount A6 of the second balance are the placement of the products used for comparison from the weight data stored in the weight value A3 for the first balance and the weight value A4 for the second balance, respectively. This is an area for storing the amount of change in weight at the time of taking out or taking out. When determining the coincidence of the weights at the time of the weight comparison, an allowable range of a certain weight error is provided.

 The first time product data storage unit A7 scans the product barcode for the first time when registering the product, reads product data based on the product code, and temporarily stores the product name, price, and weight data of the read product. Area. The second product data storage unit A8 is an area for storing the product data of the product scanned for the second time at the time of product registration. When there are three or more products to be registered, an area of the product data storage unit is added and stored sequentially, such as a third product data storage unit and a fourth product data storage unit.

 FIG. 4 is a diagram showing an example of the product file A2 stored on the RAM 303. As shown in FIG. The product file A2 shown in FIG. 4 stores the product number, product code, product name, price data, weight data, weight input flag, weight invalid flag, period data, and weight provisional data for each product. Has been. The weight input flag stores “1” when the set weight data is the weight data calculated based on the first scale unit or the second scale unit, and the numeric key of the key operation unit 102 and the confirmation key Or “0” is stored when the weight data is set and numerically input by displaying and confirming with the numeric key and the first liquid crystal touch panel 101. The weight invalidation flag is a flag for invalidating the set weight data for a set period, for a product whose gross weight increases due to a certain period, such as a special sale period, or a product whose internal capacity increases. Even if the weight data is set, if “1” is stored, the set weight data is invalidated. When “0” is stored, the set weight data is validated.

 The period data sets a period during which the weight invalid flag functions, that is, a period in which whether or not the product registration is appropriate is determined based on the weight data even if the weight data is set. The weight invalid flag will work until January 1 of the year. The CPU 300 switches between enabling / disabling the weight invalid flag by comparing the data from the clock function in the self-scanning system with the period data in the product file A2.

 The provisional weight data sets the weight as the weight of the product when the same product is weighed three times, for example, when the measurement result is within the error range three times. When setting the weight, the number of measurements may be set once. In addition, when setting weight data, you may make it set also about the date data of measurement.

 Next, the operation content of this embodiment will be described. FIG. 5 is a flowchart showing the processing operation of the self-scanning system according to the first example of the present embodiment. In step S101, when a customer places a product basket on the first weighing unit 104 and the registration start key is pressed by the key operation unit 102, the output is output from the first weighing unit and the second weighing unit at the start. The weight data is stored in the first and second weight values A3 and A4 for the RAM 303. In step S102, the product is taken out from the basket placed on the first balance unit 104, and the weight value of the first balance and the weight change amount of the first balance caused by the removal are the weight value A3 for the first balance in the RAM 303. And stored in the weight change amount A5 of the first balance.

 In step S103, the barcode attached to the product is scanned by the scanner unit 103. In step S104, the corresponding product data is read from the product file A2 from the data scanned in step S103 and stored in the first product data storage unit A7. In step S105, it is determined whether or not weight data is set in the product data read in step S104. If yes, the process proceeds to step S106. If not, the process proceeds to step S110.

 In step S106, it is determined whether or not the weight change amount A5 of the first balance stored in the RAM 303 matches the weight data in the product data stored in the first product data storage unit A7 in step S104. If they match, the process proceeds to step S107. If not, the process proceeds to step S113. In step S107, the product is registered. In step S108, it is determined whether there is a product to be registered next. If there is, the process proceeds to step S102. If not, the process proceeds to step S109.

 In step S109, the completion key is pressed in the key operation unit 102, and the process is terminated. In step S110, the weight data of the weight change amount A5 of the first balance is set in the weight data of the product file. In step S111, it is determined whether or not the processing for setting the weight data in the product file in step S110 is completed. If completed, the process proceeds to step S107, and if not completed, the process proceeds to step S112. In step S112, the first liquid crystal touch panel 101 displays that weight data has not been set and product registration is prohibited, and the process proceeds to step S111. In step S113, an error display indicating that the weight data does not match is displayed, and the product is returned to the first scale unit and prompted to take out the product again.

 In this way, even if you forget to set the weight data in the product file, the weight data calculated from the scale is set in the product file, so that the product registration is not interrupted by an error as in the past. In addition, since the weight of the actual product measured by the scale unit is set in the product file, whether or not the product registration is appropriate is determined based on the correct weight data in the next product registration. Even if the setting is forgotten, it is not necessary for the store clerk to set it, so the operability is improved. In addition, while the weight data is set in the product file, a message indicating that the product cannot be registered is displayed, so that the customer can be prevented from registering the next product by mistake.

 The weight to be compared with the weight read from the product file may be the increased weight after registration, that is, the weight change amount (increased) of the second scale unit. The data when setting the weight data in the product file may also be the amount of change in the weight of the second scale unit. When comparing the weight change amount (reduced amount) of the first balance unit with the read weight data, only the first scale unit may be used, or the weight change amount (increased amount) of the second scale unit. And the read weight data, only the second scale unit may be used. Further, when the weight data is set in the product file in step S110, “1” is set in the weight input flag of the product file in order to identify the weight measured by the first scale unit or the second scale unit. May be set. Thereby, the origin of the set weight data can be known.

 FIG. 6 is a flowchart showing another example of the processing operation when setting the weight data according to the first example of the present embodiment. When setting the weight data of the weight change amount A5 of the first balance in the weight data of the product file in step S110 of FIG. 5, the weight data is not set by one measurement but the result of multiple measurements is weighted. The contents are stored in the provisional data and stored as the weight data of the product file when, for example, all of the provisionally stored weight data is within the error range based on the provisional weight data. The processing operation of FIG. 6 shows an operation when, for example, three pieces of weight data to be compared are set as the provisional weight data. The count data that is counted up each time the provisional weight data is set may be stored for each product in the product file, or may be stored in the RAM 303 separately from the product file.

In step S120, it is determined whether weight data is set in the read product data. This corresponds to the processing operation of step S105 in FIG. If yes, the process proceeds to step S126. If not, the process proceeds to step S121.
In step S126, the weight data is already set in the product data of the read product, and this corresponds to the processing operations in steps S106 and S113 in FIG.
In step S121, the count data of the provisional weight data of the read product data is referred to.
In step S122, it is determined whether the count is 2 or other.
In other words, when comparing the three weight data as the provisional weight data, if the count data is 2, the two weight data are already stored as the provisional weight data. Three weight provisional data are obtained. If the count data is 0 or 1, provisional data is not stored or only one provisional data is stored. Since the number does not reach 3, the next measurement data can be stored as provisional data. If the count is 0 or 1 other than 2, the process proceeds to step S123, and if the count is 2, the process proceeds to step S124.

In step S123, the weighing data is stored in the product file as provisional weight data. In step S124, the current weighing data is stored as the provisional weight data, and the three data of the two weight data stored as the provisional weight data and the weighing data stored this time are all within the error range. Determine whether or not.
If it is within the error range, the process proceeds to step S128, and if any one of the three data is not within the error range, the process proceeds to step S125.
In step S125, all the stored three temporary weight data are cleared, and the process proceeds to step S127.

In step S128, for example, an average value of the three weight data stored as the provisional weight data is set as weight data in the weight column of the product file.
Then, after setting in the product file as the weight data of the product, the three provisional data stored as the provisional weight data are cleared.
In addition to setting an average value, the value set as the weight data may be set, for example, as the weight data measured for the third time, or the temporary data stored for the first time as the weight data. You may make it memorize | store.
In step S127, the product is registered. This corresponds to the processing operation of step S107 in FIG.

 FIG. 7 is a flowchart showing the processing operation of the self-scanning system according to the second example of the present embodiment. In the second example, when the product data at the time of product registration described in the first embodiment is read and weight data is not set, the first scale unit or the second scale unit is used. Using the function of setting the weight data based on the weighing data output from the department as the weight data of the product, when a new product is received and the weight of the product must be set, or at a new store This is an example in which a store clerk registers a product when it is necessary to input weight data of all products. That is, in this case, since the purpose is to set the weight data for the read product to the last, control is performed so as not to add to the actual data generated by the registration by the normal customer.

 In step S <b> 201, the clerk mode is selected by the key operation unit 102. When the clerk mode is selected, even if the product is registered, it is not added to the normal purchase record file. In other words, when the product is registered by the customer, the number of scans of the result file consisting of the product code of the product and the number of scans thereof is counted up one by one, but after the store clerk mode is selected The registration is prohibited from counting up. In step S202, when a product basket is placed on the first weighing unit 104 by the customer and the registration start key is pressed by the key operation unit 102, the first weighing unit and the second weighing unit at the start are output. The weight data is stored in the first and second weight values A3 and A4 for the RAM 303.

 In step S203, the product is taken out from the basket placed on the first balance unit 104, and the weight value of the first balance and the weight change amount of the first balance generated by the removal are the weight value A3 for the first balance in the RAM 303. And stored in the weight change amount A5 of the first balance. In step S204, the barcode attached to the product is scanned by the scanner unit 103. In step S205, the corresponding product data is read from the product file A2 from the data scanned in step S203 and stored in the first product data storage unit A7.

 In step S206, it is determined whether or not the product data read in step S205 has a weight data setting. If there is, the process proceeds to step S207, and if not, the process proceeds to step S210. In step S207, it is determined whether or not the weight change amount A5 of the first balance weighed in step S203 matches the weight data of the product data stored in the first product data storage unit A7 in step S205. If they match, the process proceeds to step S208. If they do not match, the process proceeds to step S211.

 In step S208, it is determined whether there is a product to be registered next. Next, if there is a product to be registered, the process proceeds to S203, and if not, the process proceeds to S209. In step S209, the completion key of the key operation unit 102 is pressed to complete the process. In step S210, the weight data of the weight change A5 of the first balance is set in the weight data of the product file A2, and the process proceeds to step S208. In step S211, an error message indicating that the weight data does not match is displayed, the product is returned to the first scale unit, and the product is prompted to be taken out again.

 Thus, when the store clerk sets the weight data of each product in the product file, the weight data is set in the product file simply by taking out and specifying the product placed on the scale unit. It is possible to set weight data without carrying out complicated operations such as weighing one and manually inputting into a product file. In addition, it is possible to record only the purchase record by the customer by preventing the product registration by the store clerk from being added to the purchase record.

 In the above-described embodiment, the clerk mode is selected from the key operation unit 102. However, the present invention is not limited to this, and for example, reading means for reading information in which the clerk number for identifying the clerk is barcoded before starting the product registration. If the registration start key is pressed after the information has been read, it may not be counted up in the result file as in the clerk mode. Even when the clerk mode or the information in which the clerk number is barcoded is read, the result file is counted, and when the completion key in step S108 is pressed, the clerk mode in the result file is selected. Or the record data registered after the information in which the store clerk number is converted into a bar code is read.

 Also, a store clerk result file different from the normal track record file is provided, and the results of the scanned products after the store clerk mode is selected are stored in the store clerk track record file so that they are not registered in the normal track record file. good. As a result, it is possible to easily confirm the contents related to the work of setting the weight data (which product has been weighed). Further, the weight data to be compared with the weight data read from the product file may be data for the weight change increased by the second scale unit 105.

 FIG. 8 is a flowchart showing the processing operation of the self-scanning system according to the third example of the present embodiment. At the end of the process of FIG. 8, the registration completion key of the key operation unit 102 is pressed to end the process. In step S301, in step S202, when a product basket is placed on the first scale unit 104 by the customer and the registration start key is pressed by the key operation unit 102, the first scale unit at the start, The weight data output from the scale unit is stored in the first and second weight values A3 and A4 for the RAM 303.

 In the first and third embodiments, after the product registration is completed by the customer in the product registration unit 1, the product registration unit 1 presses the call key displayed on the second liquid crystal touch panel of the product settlement unit 2. The registered data and the total purchase amount are displayed, and the customer can complete the settlement by inserting the amount into the accompanying automatic change machine 22. In addition, a receipt issuing unit is provided in the product registration unit 1, and after the product registration is completed, a receipt in which information for reading registration data is converted into a barcode is issued from the receipt issuing unit, and the receipt is read at another place. In the same manner as the merchandise settlement section, the settlement may be performed. Further, for example, a store clerk may only perform payment at another place.

 In this way, if weight data is not set for the specified product, the calculated weight data is set in the product file. In this case, if the changes in the weight data before and after product registration match. Since it can be regarded as correct merchandise registration, it is possible to register merchandise accurately even when weight data is not set. In addition, for example, when a product is discounted only for a certain period of time, or when it is sold with increased content as a special sale product, the weight data is temporarily invalidated and the weight change before and after product registration matches to register the product By determining whether or not the product is appropriate, it is possible to register the product without changing the weight data even when the content is increased for a certain period such as during a special sale period.

 Although the weight data is set and stored in the product file, the present invention is not limited to this. For example, the weight data may be stored in a dedicated file in which only the weight data is stored. In this case, what weight data is which product code, and the product and weight data may have a one-to-one relationship.

 In the above embodiment, two examples of registration, i.e., product registration by the customer and product registration performed by the store clerk for weight setting, are shown. In the busy hours of the day, the store clerk registers the product like a normal cash register instead of the customer, that is, when one device can be switched between the customer and the store clerk. The key etc. which distinguishes the salesclerk mode which does not add the performance data shown in the embodiment to the performance file and the salesclerk mode where the salesclerk registers instead of the customer and adds the performance data like the operation at the normal cash register You may make it provide.
