  Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a configuration diagram of a cart according to the present embodiment. A mechanical structure such as a frame of the cart 1 is generally used in a store such as a supermarket. The cart 1 allows a user to place a plurality of shopping carts for putting a favorite product and carrying it in the store temporarily.

  The cart 1 has a plurality of wheels 3 below the frame 2 and is movable. The frame 2 has a support base 4 that extends in the horizontal direction and supports a scale described later. A handle 5 for pushing the cart 1 is connected to the frame 2. A scanner 7 and a display 8 are disposed on the side of the frame 2 facing the handle. The scanner 7 incorporates an optical sensor that reads a barcode attached to a product, and can digitize the read barcode data and transmit it to the outside. The display 8 is capable of displaying data received from the outside, and a liquid crystal display type display is employed in this embodiment. This display 8 has a transparent touch panel 9 on its surface. The touch panel 9 can detect that the operator has pressed the position of a button displayed on the screen of the display 8 with a finger, and transmits the detection result to the outside.

  Although the scanner 7 and the display 8 are disposed on the upper part on the side facing the handle 5 for ease of use by the operator, the present invention is not limited to this. You may provide in the vicinity of the handle | steering-wheel 5 from an operator's usability.

  A scale 6 is disposed on the upper part of the support 4. An open space is provided between the side of the frame 2 where the scanner 7 and the display 8 are disposed and the handle 5 side. The shopping cart 11 can be detachably placed in this space. In the present embodiment, an example in which one shopping cart 11 is placed has been shown, but two or more may be placed. The cart 1 is configured such that the bottom of the shopping cart 11 always comes into contact with the balance 6. The scale 6 can measure the weight of the shopping basket 11 including the products put inside, and can output the weight to the outside as electronic data.

  A control BOX 10 is disposed near the lower portion of the cart 1. The control BOX 10 is electrically connected to the scale 6, the scanner 7, the display 8, and the touch panel 9, and has a cart control unit for controlling them. Details of the cart control unit will be described later. Although only one scale 6 is connected to the cart control unit in the present embodiment, for example, it may be further provided in a vacant space next to the control BOX 10 at the bottom of the cart 1 in FIG.

  Since there are a plurality of carts 1 in the store as described above, each cart has an identification number. This identification number is held by the control BOX 10 and is displayed on the display 8, for example, so that it can be visually recognized. Of course, it may be physically marked on the frame of the cart without being displayed on the display 8.

  FIG. 2 is an overview of the POS register 20 of the present embodiment. The POS register 20 includes a keyboard 21, a handy scanner 22, a display 23, and a receipt printer 24. The control unit 26 is built in the housing of the POS register 20 and controls the units such as the keyboard 21. An independent drawer 25 is disposed at the bottom of the casing of the POS register 20.

  The keyboard 21 receives input from an operator and has a plurality of keys. Each of the plurality of keys is assigned a different usage. Examples of this use include the numbers 0 and 1 to 9, and “subtotal” and “current / saving” which will be described later.

  The handy scanner 22 optically reads a barcode attached to a product. As an example, the handy scanner 22 scans an infrared laser in one direction and reads reflected light from the barcode with a CCD sensor. The handy scanner 22 is not limited to the structure as described above. For example, a two-dimensional CCD used in a digital camera or the like is used to obtain the barcode vicinity of the product as image data, and the barcode is obtained by image processing analysis. Applicable to identification / reading. The barcode may be a two-dimensional system as well as a one-dimensional system.

  The display 23 displays various information. For example, from the product code corresponding to the barcode read by the handy scanner 22, individual information such as the name, price, and quantity of the corresponding product, the total product price for each transaction, and the like are displayed. A transparent touch panel is arranged on the surface of the display 23 and can accept input from the operator.

  The receipt printer 24 prints the contents of the transaction when the transaction is established and outputs a receipt. As the output method, a heat-sensitive type in which the receipt paper is colored by heat is used. However, the output method is not limited to this, and a known method such as an ink jet recording method can be applied.

  The drawer 25 stores banknotes and coins used for sales and fishing. These POS registers 20 are arranged on a cash register 27. Next to the cash register 27, a soccer stand 28 is arranged. The soccer stand 28 is for placing products brought in by the customer when performing transaction work.

  FIG. 3 is a block diagram showing the system of this embodiment. In this system, a cart control unit in the control BOX 10 of the cart 1, a control unit 26 in the POS register 20, and a server 40 that manages the store are connected to each other by a wireless or wired network.

  The cart control unit in the control box 10 of the cart 1 has a cart CPU 30 on the board, and controls the entire control unit. Connected to the control bus connected to the cart CPU 30 are a ROM 31 for storing programs, a RAM 32 for temporarily storing data, a display controller 33 for connecting and controlling the display 8, a touch panel controller 34 for connecting and controlling the touch panel 9, and a scanner 7. A scanner controller 35 for controlling, a scale controller 36 for connecting / controlling the scale 6, and a wireless LAN controller 37 for communicating with the outside are connected to exchange data with the cart CPU 30. An antenna 38 is connected to the wireless LAN controller 37, and known wireless communication (for example, IEEE 802.11 or other short-range wireless communication) is possible.

  The ROM 31 holds programs for controlling various controllers on the board, and also holds the identification number of the cart 1. This identification number is transmitted via the wireless LAN controller 37 in response to an external request or the like.

  The RAM 32 has a registered product table as a data table. The contents of this registered product table will be described later. Further, the system configuration may be configured to store a PLU (Price Look Up) table, which will be described later.

  The server 40 is controlled by the main CPU 41. A control bus connected to the main CPU 41 includes a ROM 42 for storing programs, a RAM 43 for temporarily storing data, an HDD 44 having a larger capacity than the RAM 43, a wireless LAN controller 45 for wireless communication with the control unit of the cart 1, and wired. A LAN controller 46 for connecting to a network is connected. These devices can exchange data with the main CPU 41. An antenna 47 is connected to the wireless LAN controller 45. In addition to these, an uninterruptible power supply device having a backup function in the event of a power failure may be connected as necessary.

  The RAM 43 or HDD 44 of the server 40 stores a PLU table, which will be described later, and the main CPU 41 searches and extracts the corresponding data in the PLU table in response to each inquiry from the control unit of the cart 1 and the POS register 20. The corresponding data is transmitted to the request source via the wireless LAN controller or the LAN controller 46.

  The control unit 26 of the POS register 20 is controlled by the POS CPU 50. A control bus connected to the POS CPU 50 includes a ROM 51 for storing a program, a RAM 52 for temporarily storing data, a scanner controller 22 for connecting and controlling the handy scanner 22, and an input device for connecting and controlling a touch panel on the keyboard 21 and the display 23. A controller 54, a display controller 55 for connecting / controlling the display 23, a LAN controller 56 for transmitting / receiving data to / from the server 40 via the network, and a printer controller 58 for connecting / controlling the printer 24 are connected. These devices can exchange data with the POSCPU 50. The LAN controllers 46 and 56 are connected by a known network 57.

  FIG. 4 is a configuration diagram of the PLU table and the registered product table of the present embodiment. FIG. 4A shows an example of the configuration of the PLU table. The PLU table has a plurality of product records each including product name, unit price, weight, and weight threshold data corresponding to the product code. The merchandise code coincides with a bar code attached to the merchandise optically read by the scanner 7 or the handy scanner 22 and digitized. The cart CPU 30 and the POS CPU 50 transmit the read product code to the server 40 via the network. The main CPU 41 searches for and extracts a product record that matches the received product code from the PLU table stored in the HDD 44, and returns the data in the product record to the request source.

  Each record of the PLU table stores weight and weight threshold data separately. The weight indicates an average value of the weight of the corresponding product. The weight threshold indicates an allowable range of deviation from the weight average value of the corresponding product. The allowable range of this deviation is set in consideration of the reading error of the scale 6 of the cart 1 and the product-specific error. The allowable weight range of the product is determined by combining the weight and weight threshold data.

  For example, in the case of “vegetable A” with the product code “1000001”, the weight is “200 g” and the weight threshold is “± 30 g”, so the allowable weight is 170 g to 230 g. In this embodiment, the allowable weight range is determined based on the weight and weight threshold data. However, the upper limit value and the lower limit value may be provided, and the allowable weight range may be provided as data. That is, taking the case of “vegetable A” as an example, the upper limit value is 230 g and the lower limit value is 170 g. Hereinafter, data that combines the weight and the weight threshold is referred to as allowable weight.

  FIG. 4B is an example of a registered product table held in the RAM 32 of the control unit of the cart 1 and the RAM 52 of the POS register 20. The registered product table includes a No indicating the reading order, a product code, a product name received from the server 40, a unit price, actual product weight data received from the scale 6, actual product weight data received from the scale 6, and a server. 40 has registered product information (hereinafter referred to as a registration record) including an error flag indicating a check result obtained by comparing the allowable weight received from 40. The error flag stores “0” when the actual weight data is within the allowable weight range, and “1” when the actual weight data is out of the range.

  FIG. 5 is an overall flowchart of the cart control unit of the present embodiment. This flowchart is executed by the cart CPU 30 and shows the processing from the start of use of the cart 1 to before the customer makes a transaction. Control is started from a state in which the cart control unit is turned on, and a start processing routine (ST1) is executed. When the start processing routine ends, the customer is permitted to start shopping. Each time a barcode is read by the scanner 7, a scan processing routine (ST2) and then a cancellation processing routine (ST3) are executed, and ST2 and ST3 are executed in sequence while the customer is shopping. When the customer declares the end of shopping (ST4), the pre-accounting processing routine (ST5) is executed and the processing ends.

  Next, the start processing routine will be described with reference to FIG. 6 and FIG. FIG. 6 is a flowchart of the start processing routine, and FIG. 10A is a display example of the display 8 of the cart 1. When the start processing routine starts, the cart CPU 30 instructs the display controller 33 to display the image shown in FIG. 10A on the display 8 (ST10). This initial screen has a cart number which is an identification number of the cart and guidance information for the customer, and has a button 60 for declaring the start of shopping.

  As guidance information, for example, information prompting to place the shopping cart 11 on the cart 1 is displayed. This is for checking the initial weight output from the scale 6 at the start of shopping. When the touch panel 9 detects that the button 60 has been pressed, the cart CPU 30 recognizes that the customer has pressed the button 60 via the touch panel controller 34. The cart CPU 30 requests the balance controller 36 to transmit weight data, and the initial weight is transmitted from the balance 6 to the cart CPU 30 via the balance controller 36. The cart CPU 30 stores the received initial weight data in the RAM 32 (ST12). Based on the initial weight, the cart CPU 30 performs a weight check described later, and registers the result in the registered product table.

  When the start process routine (ST1) ends, the scan process routine (ST2) starts. The scan processing routine will be described with reference to the flowchart of FIG. The cart CPU 30 requests the current weight data from the scale controller 36 (ST20). When the cart CPU 30 has just shifted from the start processing routine, the cart CPU 30 compares the initial weight data stored in the RAM 32 with the weight data received from the balance controller 36 at this time, and checks whether there is any fraud. If the scanner 7 has already read the product, it is compared with the latest total weight data received from the scale controller 36. The latest total weight is also stored in the RAM 32. Hereinafter, unless otherwise specified, the most recent total weight including the initial weight is indicated.

  Upon receiving notification from the scanner controller 35 that the scanner 7 has read the barcode, the cart CPU 30 adds a registration record in the registered product table and registers the product code (ST21). At this time, “No” is automatically given in the order of registration. When the registration is completed, various information for the corresponding product code is acquired from the server 40 (ST22). Specifically, the product code is transmitted to the server 40 via the wireless LAN controller 38 together with the data request signal. The main CPU 41 of the server 40 searches the PLU table in the HDD 44 for a product record that matches the product code of the data request target via the wireless LAN controller 45. If there is a match, the corresponding product record data is transmitted to the control unit of the cart 1 via the wireless LAN controller 45. The cart CPU 30 writes the data of the received record at a predetermined address corresponding to the “product name” and “unit price” fields of the corresponding registered record in the registered product table (ST23).

  Next, the cart CPU 30 requests weight data from the scale controller 36 and calculates the difference between the latest total weight and the weight data from the scale controller 36. This difference data is written as a real weight at a predetermined address of the corresponding registration record. At this time, the weight data received from the balance controller 36 is stored in the RAM 32 as the latest total weight (ST24). It should be noted that there is a time lag between the reading by the scanner 7 and the actual product being put into the shopping basket 11, and the weight controller 36 continues to request weight data for a predetermined time, and the subsequent weight check The cart CPU 30 controls so as not to carry out.

  The allowable weight received from the server 40 is compared with the actual weight (ST25), and if the actual weight is within the allowable range, “0” is written in the address corresponding to the “error flag” field (ST26). If it is determined that the value is outside the allowable range, “1” is written to the corresponding address in the “error flag” field (ST27), and a message notifying that a weight error has occurred is displayed on the display 8.

  FIG. 10B shows a message display example when there is a weight error. In this display example, the image data of the read product, the unit price of the registration record, the number of purchases, and the subtotal amount information are displayed, and the announcement information “Is the product wrong?” Is displayed. This saves, for example, an unexpected heavy product as an exception. If the correct product is read, the customer presses the button 61 for “continue”. When this button 61 is pressed, the “error flag” field of the registered product table holds a state of “1”, and is distinguished as a product to be checked by a person in charge (cashier) at the stage of accounting processing described later. This is to make it possible. When an incorrect product is read by the scanner 7 due to a customer's operation mistake, the subsequent cancel routine is started by pressing the button 62 as a correction intention display.

  Next, the cancellation processing routine will be described with reference to FIGS. FIG. 8 is a flowchart of the cancellation processing routine, and FIG. 11 shows a display example on the display 8. As shown in FIG. 11A, the cart CPU 30 displays the product name, unit price, points, and subtotal of the product read by the scanner 7 on the display 8 in a single line and displays a plurality of lines within a range in which the read product can be displayed. An image is configured so that display is instructed to the display controller 33. In addition, the sum total of the subtotals is given to the image.

  Each line displaying the product information is provided with a column for adding a mark for distinguishing the selection result to be canceled. This column can also be marked with the user's intention. Specifically, when the user presses the corresponding column with a finger, the touch panel controller 34 specifies the pressed position and notifies the cart CPU 30, The cart CPU 30 generates data with a mark in the corresponding column and instructs the display controller 33 to display the data. This mark is automatically given when the button 62 is pressed in ST28 of the scan processing routine. This mark distinguishes the products to be canceled.

  The display 8 displays a button 63 for determining the end and a button 64 for determining the deletion of the marked product at the bottom thereof. When the cart CPU 30 determines that the button 63 has been pressed, the process proceeds to a pre-accounting processing routine described later. When the cart CPU 30 determines that the button 64 has been pressed (ST30), the display 8 displays a guidance image as shown in FIG. 11B (ST31), assuming that the item with the mark is deleted. When product data is newly input from the scanner 7, the cart CPU 30 ends the cancel routine and starts the scan processing routine.

  FIG. 11B is a display example of cancellation guidance. The display 8 displays confirmation of whether or not to cancel the product with the mark (in this case, vegetable B), and guidance prompting the scanner 7 to read the product to be canceled again. A button 65 for canceling the cancellation is displayed. After this guidance is displayed, when the customer brings the corresponding product closer to the scanner 7 and the scanner 7 reads the barcode of the product (ST32), the cart CPU 30 is included in the registration record of “vegetable B” in the registered product table. Erase all data that is stored. Whether or not the “error flag” field of the “vegetable B” registration record is “1” is not considered.

  When a plurality of marks are given, the same guidance is displayed again, and a message prompting the scanner 7 to read the barcode is displayed. When the reading and deleting of all the mark target products is completed, the cart CPU 30 requests weight data from the scale controller 36 and stores the received weight data in the RAM 32 as the latest total weight (ST34).

  Next, the accounting pre-processing routine will be described with reference to FIG. When the cart CPU 30 recognizes that the customer has pressed the button 63 shown in FIG. 11A, the transaction pre-processing routine is started. The cart CPU 30 calculates the total actual weight of the products registered in the registered product table (ST40). Weight data is requested from the scale controller 36, and the latest total weight is stored in the RAM 32 (ST41). The latest total weight is compared with the calculated actual weight total (ST42), and if it is determined that there is no difference, the total error flag is set to “0” (ST43). If there is a difference, the total error flag is set to “1” (ST44). The total error flag is for comparing the total value of the actual weight data in the registration record from the start processing routine to the pre-accounting processing routine with the latest total weight. This is for inspecting whether or not there is a product put in the shopping cart without being registered by the scanner 7.

  Next, the identification number of the cart 1, the total error flag, and the registered product table data are collected. This summarization processing indicates, for example, data concatenation processing, compression processing, encryption processing, and the like. The cart CPU 30 transmits the data for which the summarizing process is completed to the server 40 via the wireless LAN controller 37 (ST45). The server 40 stores the received data in the RAM 43 and / or the HDD 44. If it is determined that the data transmission is completed, the cart CPU 30 clears the registered product table and the total error flag stored in the RAM 32, and returns to the initial state (ST46).

  Next, the accounting process will be described with reference to FIGS. FIG. 12 is a flowchart of the accounting process, which is performed by the control unit 26 in the POS register 20. When the cart identification number is input from, for example, the keyboard 21 (ST50), the POS CPU 50 requests data including a registered product data table corresponding to the identification number to the server 40 via the LAN controller 56. The server 40 retrieves and extracts data corresponding to the received identification number from the HDD 44 and transmits it to the POS register 20 via the LAN controller 46. The POS CPU 50 checks whether or not the identification number attached to the received data matches the requested identification number, and if it is the same, stores it in the RAM 52 (ST51).

  The POS CPU 50 checks whether there is “1” in the total error flag of the data stored in the RAM 52 and the error flag of each registration record in the registered product table. When all of the total error flag and the error flag are “0”, an image as shown in FIG. 14 is displayed on the display 23. If either or both of the total error flag and the error flag are “1” (ST52), the confirmation image shown in FIG. 13 is displayed on the display 23 to prompt correction (ST53).

  As shown in FIG. 13, the contents displayed on the display 23 are those in which the error flag is “1” among the registration records of the registered product table, and are displayed in the error product area 80 in a list format. The error product area 80 is displayed separately from other products so that the cashier on the store side can easily see the product with the error flag. This list includes No, product code, product name, and unit price among the contents of the registered product table. Although not shown, the number of points (the number of registrations) may be displayed. In the error product area 80, a button 66 for inputting “confirmation” when there is no problem when the cashier checks the product with the error flag in the shopping cart 11 and there is no problem, and “correction” when correction is necessary. A button 67 for inputting is arranged. If there are a plurality of products on the list, these buttons 66 and 67 are arranged for each product.

  When it is confirmed that the button 66 has been pressed, the POS CPU 50 rewrites the error flag of the target record from “1” to “0”. If it is confirmed that the button 67 has been pressed, the target record is deleted from the registered product table, and a message prompting the cashier to register the correct product is displayed.

  In the lower part of the error product area 80, an OK product area 81 for extracting those with an error flag of “0” and displaying them in a list format is arranged. On the list, No, product code, product name, unit price, number of points, and subtotal are displayed. The subtotal is an amount obtained by multiplying the unit price of the product by the score (number). When the cashier presses the button 66 or corrects the correct product by pressing the button 67 for the product whose error flag is “1”, the target product is deleted from the error product area 80 and the OK product area 81 is displayed. To display.

  A total area 82 is arranged below the OK product area 81. In the total area, the number of products displayed in the error product area 80 and the number of products displayed in the OK product area 81 are displayed. When the total error flag is “1”, “Weight error” is displayed. When this display is present, the cashier performs matching of all the products with each list on the assumption that there is a possibility that a product not included in each list in the error product area 80 and the OK product area 81 is included in the shopping cart 11. When a product not found in each list is found, the barcode is read by the handy scanner 22 and a registration record is added to the registered product table. When confirmation is obtained, the button 68 is pressed. Upon confirming that the button 68 has been pressed, the POSCPU 50 rewrites the total error flag from “1” to “0”.

  When at least one of the total error flag and the error flag is rewritten from “1” to “0”, the POS CPU 50 searches again for the total error flag and the error flag in the data. Update the confirmation screen. If there is no “1” (ST54), the image of FIG.

  FIG. 14 shows a display example of the accounting process. In the center of the display area of the display 23, a registered product area 83 for displaying a list of products for which the data of the registered product table and the actual product are matched by the cashier is arranged. In this list, No, product code, product name, unit price, points, and subtotal are displayed. In the lower part of the registered product area 83, the total number of products in the list and the sum of all subtotals are displayed. In consideration of the possibility of additional purchase of another product, reading of a barcode by the scanner 22 is permitted. When the barcode is read, the POS CPU 50 reads the product code from the barcode and requests the server 40 for the corresponding product record. The server 40 searches and extracts the corresponding product record and returns it to the POS register 20.

  The POSCPU 50 adds the product record to the registered product table. When, for example, an amount discount (for example, a 50 yen discount or a 20% discount) is accepted by inputting a cashier button, the discount amount is recorded in a discount price column (not shown) of the target registration record.

  When all product registrations are completed, the cashier presses the subtotal button 69. When the POS CPU 50 confirms that the subtotal button 69 has been pressed (ST55), the POS CPU 50 provisionally confirms the data of the registered product table. When the cashier deposits cash from the customer, inputs the deposit amount with the keyboard 22, and presses the current / deposit button 70, the POSCPU 50 confirms this (ST56) and confirms the data of the registered merchandise table. If the current / save button 70 is pressed without pressing the subtotal button 69, an error is displayed. The current / save button 70 may not be activated until the subtotal button 69 is pressed.

  If there is a difference between the entered deposit amount and the total amount, the change amount is displayed and the drawer 25 is opened. Further, the POS CPU 50 instructs the printer controller 58 to print out the data of the registered product table, the deposit amount, and the change amount on the receipt. The printer controller 58 prints a receipt by superimposing the received data on predetermined format data.

  In the present embodiment, the cart 1, the POS register 20, and the server 40 each have a CPU. For example, only the server 40 has a CPU, and the cart 1 and the POS register 20 have only an input function and a display function. You may comprise so that it may have. In this case, the CPU of the server 40 manages all data and executes the processing flow.

  In this embodiment, the PLU table is stored in the server 40 and the cart 1 and the POS register 20 make an inquiry. However, the cart 1 and the POS register 20 may each have a PLU table. In addition, various modifications can be made without departing from the spirit of the present embodiment.

  As described above, according to the embodiment of the present invention, it is possible to easily confirm a mistake that occurs when the customer himself / herself reads a barcode with a scanner.
