Description

The present invention relates to a product sales data processing system and a product sales data processing device .

Technology has been proposed for registering products placed in a showcase (see, for example, Patent Document 1). One technology for registering products sold by weight is to register products using a detection device that can detect human contact such as touching. With this technology, a detection device is provided for each product, and the product is weighed and registered as the product that corresponds to the detection device that was touched.

JP 2004-206197 A

The above detection devices are relatively expensive, so there is a problem in that the introduction of the above technology is costly. In particular, because a detection device is provided for each product, the cost increases in proportion to the number of products, so if there are a large number of products, enormous costs are required.

The present invention was made in light of these circumstances, and its purpose is to provide a technology that enables the registration of bulk products at low cost.

In order to solve the above-mentioned problems, a product sales data processing system according to one aspect of the present invention is a product sales data processing system comprising a mobile terminal capable of acquiring product identification information and a product sales data processing device capable of weighing a product, the mobile terminal comprising a clerk identification acquisition unit that acquires clerk identification information that identifies the clerk carrying the mobile terminal, a product identification acquisition unit that acquires the product identification information, and a transmission unit that transmits the product identification information acquired by the product identification acquisition unit and the clerk identification information acquired by the clerk identification acquisition unit to the product sales data processing device, the product sales data processing device comprising a registration unit that registers a product identified by the product identification information transmitted by the transmission unit, and a processing unit that performs a predetermined process determined for each clerk identified by the clerk identification information transmitted by the transmission unit.

Figure 1 (A) shows an overview of a store to which the product sales data processing system of this embodiment is applied. The store described in this embodiment is, as an example, a store that sells variable weight products and fixed weight products. Various foods are displayed as products in the display case shown in the figure. A product sales data processing device 1 is installed on top of the display case. Also, although not shown, the store clerk holds a mobile terminal, which will be described later, on his or her finger.

Fig. 1 (B) is a diagram showing an example of the configuration of a product sales data processing system 500 according to this embodiment. The product sales data processing system 500 is composed of a product sales data processing device 1 and a mobile terminal 200. The product sales data processing device 1 and the mobile terminal 200 perform wireless communication. Examples of wireless communication include Bluetooth (registered trademark), infrared communication, and short-range wireless communication (e.g., NFC (Near Field Communication)).

1B shows one product sales data processing device 1 and two mobile terminals 200, but is not limited to this. There may be a plurality of product sales data processing devices 1 and one or three or more mobile terminals 200, but a mobile terminal 200 will not communicate with two or more product sales data processing devices 1 at the same time.

Figure 2 (A) is a view of the display case from the store clerk's side. As shown in Figure 2 (A), price tags 51 are provided for the store clerk in a one-to-one correspondence with each product or type of product. Figure 2 (B) is a view of an example of a price tag 51. The price tag 51 has a display section 514 and a barcode 515. The display section 514 shows the product name and unit price. In the case of Figure 2 (B), the product name is cheese, and the price is shown as $0.77 per kilogram. The example of Figure 2 (B) shows an example of a variable weight product, but for fixed weight products, the price per unit is displayed. The barcode 515 is product identification information for identifying the product. Product identification information is uniquely determined for each product or type of product.

Figure 3 is an overall perspective view of the product sales data processing device 1. In this embodiment, the product sales data processing device 1 has a weighing device 3 (weighing unit) with a weighing function and a label printing device 2. The weighing device 3 and the label printing device 2 are connected via a connection unit 4.

In addition, in the label printing device 2 of this embodiment, the weighing device 3 is located on the front side of the label printing device 2, but the connection direction of the label printing device 2 with the connecting part 4 can be changed so that the weighing device 3 is located on the left or right side or on the back side of the label printing device 2.

The weighing device 3 has a placement section 3a, and when an object such as a product to be weighed is placed on the placement section 3a, the weight (mass) of the object (product) is measured, for example, using a load cell. The connecting section 4 houses wiring and the like inside its hollow interior. The measurement data measured on the placement section 3a is transmitted to the label printing device 2 via wiring, wireless communication, etc.

The product sales data processing device 1, which is composed of the label printing device 2 and the scale 3, is integrated via the connecting part 4, but the label printing device 2 and the scale 3 may be separate entities without the connecting part 4. The measurement data from the scale 3 is displayed on the touch-operable store clerk display operation unit 6 of the label printing device 2, along with the weight, price, etc. In FIG. 3, the side of the label printing device 2 having the store clerk display operation unit 6 is the front side, and the opposite side is the rear side, with the front side of FIG. 3 being the right side and the back side of FIG. 3 being the left side.

The label printer 2 also has an operation unit 8, which is a mechanical key, below the clerk display operation unit 6. The operation unit 8 functions as, for example, a numeric keypad or a completion key (label issuing key) required for weighing. The clerk display operation unit 6 can be reconfigured into a 15-inch display unit, and the clerk display operation unit 6, the label printer 2, and the scale 3 can be installed facing the customer, and the device can be used as a self-weighing device in which the customer operates the device and registers at least the product themselves. In this case, the customer display unit 7 of the product sales data processing device 1 can be a separate small display unit and used as the clerk display operation unit, or the clerk display operation unit 6 can be used only for customers and the customer display unit 7 can be removed.

Figure 4 is a diagram showing an example of the customer display unit 7 side of the product sales data processing device 1 according to one embodiment of the present invention. As shown in Figure 3, the display screen of the customer display unit 7 is formed on the side opposite to the display surface of the clerk display operation unit 6 of the label printing device 2 of the product sales data processing device 1.

In other words, when the clerk operating the product sales data processing device 1 and the customer are weighing the product while facing each other using the product sales data processing device 1, the customer display unit 7 faces the display screen on the side opposite the display surface of the clerk display operation unit 6 so that the customer purchasing the product can check the transaction details. The customer display unit 7 displays at least the transaction information currently being traded on the product sales data processing device 1, but may also display the transaction history so that the customer can check the details of the entire transaction.

Figure 5 is a diagram showing an example of the electrical functional blocks of the product sales data processing device 1. The product sales data processing device 1 has a control unit 111 (CPU), a memory unit 112, a scale 3 (weighing unit), a display unit (store clerk display and operation unit 6), a customer display unit 7, an operation unit 8, a printing unit 9, a sensor 10 (detection unit), a communication unit 116, etc. Each component of the product sales data processing device 1 is electrically connected by a communication line such as a bus.

The control unit 111 (CPU) comprehensively controls each component of the product sales data processing device 1, for example, by executing a control program stored in the memory unit 112. The control unit 111 also controls the store clerk display operation unit 6.

The memory unit 112 is composed of storage devices such as RAM and ROM, and stores control programs, product information related to products (e.g., product name, unit price, etc.), printing information related to printing, print format information, various setting information (data), etc. The memory unit 112 also stores store clerk identification information that uniquely identifies a store clerk and store clerk information (such as the name of the store clerk) in association with each other. The programs and information (data) stored in the memory unit 112 may be obtained from an external computer that is communicatively connected via a communication path.

The weighing unit (weighing device 3) has, for example, a load cell, measures the mass (weight) of an object (object to be weighed) such as a commodity loaded on the loading unit 3a, and outputs the weighing data to the control unit 111.

The display unit (clerk display operation unit 6) has a touch panel, a display device, etc. This clerk display operation unit 6 is configured to perform various displays under the control of the control unit 111. In addition, the clerk display operation unit 6 outputs a signal to the control unit 111 in response to operations by the operator.

The customer display unit 7 is provided with its display screen facing the opposite side to the display surface of the store clerk display operation unit 6, and under the control of the control unit 111, displays a specified message so that the customer purchasing the product can confirm the transaction details.

The operation unit 8 is a mechanical key or the like provided below the store clerk display operation unit 6, and outputs a signal according to the operation by the operator to the control unit 111.

The printing unit 9 has a print head, a cutter (not shown), etc., and under the control of the control unit 111, the print head prints product information, measurement data, etc. on continuous paper (printing medium) stored in the housing, the cutting unit (cutter) cuts the continuous paper, and issues a label from the label issuing port. In this embodiment, the continuous paper is thermal paper that can be printed with the heat of a thermal head serving as a print head, but it may be, for example, a linerless type (backing paperless type) that does not have a release paper (backing paper), or a liner type that has a release paper. The continuous paper may also be receipt paper. The communication unit 116 communicates with the mobile terminal 200 under the control of the control unit 111.

Fig. 6 (A) is a diagram showing an example of a mobile terminal 200. The mobile terminal 200 includes a reader 211 for reading a barcode on a price tag 51, and a switch 209. The mobile terminal 200 is set on the finger of a store clerk. The mobile terminal 200 is also called a ring scanner. Fig. 6 (B) is a diagram showing the state of the mobile terminal 200 set on the finger of a store clerk. The store clerk sets the mobile terminal 200 on his finger as shown in Fig. 6 (B) and has it read the barcode on the price tag in the display case. When the switch 209 is pressed and held in the off state, it turns to the on state, and when the switch 209 is pressed and held in the on state, it turns to the off state. A mobile terminal 200 in the off state cannot read barcodes.

In this embodiment, the mobile terminal 200 will be described using the ring scanner described above as an example, but the mobile terminal 200 may also be a wearable terminal (wristband type, watch type, clip type, glasses type, etc.). However, in consideration of operability, a terminal that can be worn on the hand or arm is preferable. Also, for example, it is difficult to wear a smartphone on a person by itself, but it is possible to wear it on the arm, for example, by using a smartphone holder. The mobile terminal may be one that can be worn by such other equipment.

Figure 6 (C) is a diagram showing an example of the electrical functional blocks of the mobile terminal 200. The mobile terminal 200 has a switch 209, a control unit 210, a reading unit 211, a memory unit 212, and a communication unit 213. Each component of the mobile terminal 200 is electrically connected by a communication line such as a bus. The control unit 210 comprehensively controls each component of the mobile terminal 200, for example, by executing a control program stored in the memory unit 212. As described above, the reading unit 211 reads the barcode on the price tag. The control unit 210 obtains product identification information from the read barcode. In addition to the above control program, the memory unit 212 stores the identification information of the store clerk who holds the mobile terminal 200 on his finger. The communication unit 213 communicates with the product sales data processing device 1 under the control of the control unit 210.

With this configuration, the control unit 210 transmits the product identification information obtained from the read barcode and the store clerk identification information obtained from the memory unit 212 to the product sales data processing device 1. This allows the product sales data processing device 1 to not only identify the product to be registered, but also the store clerk who is registering it. Note that the store clerk identification information stored in the mobile terminal 200 can be rewritten.

Next, we will explain the screens displayed on the store clerk display operation unit 6 of the product sales data processing device 1. Figure 7 is a diagram for explaining the screens displayed on the store clerk display operation unit 6 of the product sales data processing device 1.

The store clerk display operation unit 6 is a touch panel with a touch-operable display device for operation by an operator such as a store clerk who operates the product sales data processing device 1. As shown in FIG. 7, the store clerk display operation unit 6 has multiple display areas.

In more detail, the multiple display areas of the clerk display operation unit 6 include a first display area 11 that displays the transaction details, a second display area 21 that displays a list of registered products, a third display area 31 that displays only the selectable operation buttons required to operate the product sales data processing device 1, and a fourth display area 41 that displays the clerk information of the clerk detected by the product sales data processing device 1.

Although not shown, when preset buttons (product selection buttons 28) are displayed in the second display area 21, the third display area 31 may be used as a soft key display area and kana input keys to display each hiragana character of "aa-n" selectably, and when "a" is selected, products with names starting with "a" may be displayed on the display as selectable preset buttons.

Also, the letters A through Z may be displayed as selectable alphabet input keys. The third display area 31 is used as a soft key display area only when preset buttons (product selection buttons 28) are displayed in the second display area 21. When detailed information on the product purchased by the customer is displayed in the third display area 31, a payment button for making a payment is displayed in the third display area 31.

The first display area 11 has a container weight display section 12 that displays the weight of the container, a weight display section 13 that displays the total weight of the item being weighed, a unit price display section 14 that displays the price per unit, and an amount display section 15 that displays the amount of the weighed item. In other words, the first display area 11 is an area that displays information about the item currently being traded in the product sales data processing device 1.

The transactions carried out by the product sales data processing device 1 include transactions for variable weight products and transactions for fixed weight products. The first display area 11 is controlled to switch between displays so that when the product is a variable weight product, information such as the weighed mass and price per gram is displayed, and when the product is a fixed weight product, information such as the number of items and price per unit is displayed.

The first display area 11 also has a fifth display area 16 that displays the identification information of the store clerk operating the product sales data processing device 1 when the store clerk display operation unit 6 transitions to the registration screen. The first display area 11 shown in FIG. 7 has sales by weight display units 181, 182 that show an illustration of a weighing device and an S (scale) display, menu icons for menu selection, a time display unit, and a date display unit.

As shown in FIG. 7, the second display area 21 also has a history display area 22 that shows a list of products registered during one transaction, and a product selection button display area 23 that displays a product selection button 28 (product preset button) for the product corresponding to the received product identification information.

The history display area 22 of the second display area 21 has a weight and quantity display section 24 that displays the mass (weight) and quantity of the product, a product display section 25 that displays the name of the product, and a price display section 26 that displays the price of the product. In addition, a total price display section 27 is provided below the price display section 26 of the second display area 21.

The sales clerk who operates the product sales data processing device 1 can easily check the list of products registered in one transaction. In addition, the product list is updated (registered products are added) every time the sales clerk registers a product, so the operator can also check that a product has been registered, which has the effect of improving operability, reliability, etc.

If an abnormality occurs in the product sales data processing device 1, the error content, error number or symbol, and how to resolve the error may be displayed in priority over the product list display. Operation guidance, etc. may also be displayed in response to an operation by the operator. If no product is placed on the placement section and the weighing data from the weighing device 3 indicates less than 0, this is an abnormality that results in a negative weight output, so the control unit may display weight underflow (UF) or the like in the second display area 21. Conversely, if the weight value exceeds the scale capacity, weight overflow (OF) or the like may be displayed in the second display area 21.

The product selection button display area 23 displays a product selection button 28 for the product corresponding to the product identification information transmitted from the mobile terminal 200. The store clerk operating the product sales data processing device 1 operates the product selection button 28 in the product selection button display area 23 to identify the product to be weighed by the product sales data processing device 1 and weigh the product. Note that if the store clerk has multiple price tags read, thereby receiving multiple product identification information from the mobile terminal 200, multiple products are displayed as product selection buttons 28 in the product selection button display area 23.

When a store clerk operates the product selection button 28 and places a product on the placement section 3a, the product sales data processing device 1 weighs and registers the placed product as the product corresponding to the product selection button 28.

The third display area 31 displays only the selectable operation buttons necessary for operating the product sales data processing device 1 in the current state of the product sales data processing device 1. In other words, the third display area 31 does not display (hides) buttons that are not necessary for the current operation of the product sales data processing device 1. This allows the operator operating the product sales data processing device 1 to intuitively operate the product sales data processing device 1.

The third display area 31 shown in FIG. 7 displays a prepack button 320a as an operation button, but when the mode is different, the number and functions of the selectable operation buttons required for payment operations are changed according to the type of payment and the number of them. The prepack button 320a is a button for transitioning the screen to a prepack screen (not shown) for creating prepacked products.

In addition, in the third display area 31, while weighing an item or inputting a quantity, buttons for discounting or discounting the item are displayed, and on the sub-plan screen, buttons for payment selection, sub-total discount, and sub-total discount are displayed. Unnecessary buttons are not displayed on the operation screen, preventing operational errors and eliminating the operator's confusion about which button to select.

The fourth display area 41 displays clerk information corresponding to the clerk identification information received from the mobile terminal 200 as a clerk button (see FIG. 8 described below). If multiple clerk identification information is received, multiple clerk buttons are displayed in the fourth display area 41. When one of the multiple clerks operates the product sales data processing device 1, that clerk can operate the product sales data processing device 1 after selecting the clerk button that represents that clerk.

The sales clerk button also has the function of completing product registration. For example, the product purchased by the customer is registered in the product sales data processing device 1, and each time the sales clerk button is operated, the product is registered in association with the sales clerk button.

As a result, even if the sales clerk operating the product sales data processing device 1 is replaced by another sales clerk, products purchased by different customers can be registered alternately by switching the sales clerk who can currently operate the device using the sales clerk button. This makes it possible to efficiently, smoothly, and easily handle multiple customers even with a single product sales data processing device 1, which is both economical and effective.

In addition, if multiple product sales data processing devices 1 are connected (chained) and each data can be shared, it will be possible to link sales staff with customers even in a large sales area, allowing the sales staff to move around with customers and sell a variety of products.

The size of each of the multiple display areas of the clerk display operation unit 6, the first display area 11, the second display area 21, the third display area 31, and the fourth display area 41, may be changed depending on the display content and number of items in each area. For example, when one item is weighed in one transaction, the display area of the history display area 22 and the item selection button display area 23, which are the second display area 21, may be reduced or erased to change the proportion of the clerk display operation unit 6 that they occupy. Also, multiple areas may be combined into one area as necessary, or the area may be controlled by enlarging or reducing it.

In addition, if there are many product selection buttons to be displayed in the product selection button display area 23, the number of display lines in the weight/quantity display section 24, product display section 25, and price display section 26 in the history display area 22 of the second display area 21 may be reduced to reduce the history display area 22, and the product selection button display area 23 may be enlarged to increase the number of product selection buttons 28 displayed. In addition, the product display section 25 may be divided into multiple pages, and page navigation buttons may be displayed or flicked to navigate the product display section 25.

In this way, when the store clerk display operation unit 6 of the product sales data processing device 1 does not display operation buttons unnecessary for the current operation of the product sales data processing device 1 and increases the display of operation buttons necessary for payment according to the payment type and its number, the area of the third display area 31 is enlarged to display the necessary operation buttons according to the display content and number of items in the display area. Meanwhile, the other display areas, the first display area 11, the second display area 21, and the fourth display area 41, are reduced in area. Alternatively, the area unnecessary for the currently selected operation (area not to be operated) may be displayed in hidden form, and the area necessary for the currently selected operation (area to be operated) may be enlarged using the hidden area. This improves the operability of the operator and allows smooth operation.

In other words, the store clerk can intuitively operate the product sales data processing device 1 and can quickly perform weighing operations. In addition, the store clerk display operation unit 6 of the product sales data processing device 1 is controlled to display only the buttons currently being used to operate the product sales data processing device 1. In addition, a method may be used in which buttons not currently being used to operate the product sales data processing device 1 are not displayed (unnecessary buttons are not displayed). As a result, the store clerk can intuitively operate the product sales data processing device 1, thereby shortening the learning period required to become proficient in operating the product sales data processing device 1.

To improve convenience and operability, when no product identification information has been received, one or more product selection buttons corresponding to relatively common products may be displayed in the product selection button display area 23. Examples of operations when a product selection button is selected in this state include simply using the scale to weigh the product and printing product information and weighing data, or linking the product corresponding to the product selection button selected later by a store clerk.

When the store clerk operating the product sales data processing device 1 sets the product weight and quantity, he or she operates the clerk button, which also serves as a confirmation button, to confirm the product weight and quantity. For example, when registering cheese, the clerk has the mobile terminal 200 read the barcode on the price tag corresponding to the cheese. This causes the product selection button 28 corresponding to the cheese to be displayed. The clerk operates the product selection button 28 corresponding to the cheese and places the cheese on the placement section 3a. This causes the cheese to be weighed. The clerk then operates the clerk button to register the weighed amount of cheese.

Figure 8 shows a registration screen in which cheese is registered and then two tomatoes are weighed. In the registration screen of Figure 8, two tomatoes have been weighed and are displayed in the history display area 22 of the second display area 21. The weight quantity display section 24 of the history display area 22 displays the quantity of the selected tomatoes, two. The product display section 25 displays the name of the registered product, tomatoes. The price display section 26 displays the total price for the two selected tomatoes. The total price display section 27 calculates and displays the total price of the cheese selected before the tomato transaction and the price of the two tomatoes.

In the fourth display area 41, a clerk button 42 is displayed. The clerk button 42 displays the clerk information corresponding to the button (in the case of FIG. 8, the name of the clerk, "Clerk A"). In this way, the product sales data processing device 1 displays the clerk information stored in the memory unit 112 in association with the clerk identification information received from the mobile terminal 200.

The operator of the product sales data processing device 1 can cancel a product displayed in the history display area 22 of the second display area 21 of the registration screen in Figure 8 by clicking or double-clicking the product's weight/quantity display section 24, product display section 25, or price display section 26.

For example, an example of canceling tomatoes shown on the registration screen of FIG. 8 will be described with reference to FIG. 9. In order to cancel tomatoes, the operator of the product sales data processing device 1 touches, clicks, double-clicks, double-tap, or the like on the product's weight/quantity display section 24, product display section 25, or price display section 26, and a strikethrough 30 is displayed on the tomatoes, as in the registration screen shown in FIG. 9, allowing the product to be canceled.

In addition, the cancellation can be cancelled by touching, clicking, double-clicking, double-tapping or the like on the weight/quantity display section 24, product display section 25 or price display section 26 of the product that displays the strikethrough 30. Note that the cancellation display described above is not limited to the strikethrough 30, but may be inverted, greyed out or diagonally lined, etc.

When cancelling a fixed weight item, it is possible to cancel by changing the quantity. On the other hand, when cancelling a variable weight item, it is not possible to cancel by changing the weight. If you want to change the weight of a variable weight item, you will need to measure it again on the registration screen.

Figure 10 is a diagram showing an example of the accounting screen. The third display area 31 on the accounting screen in Figure 10 displays operation buttons 32a to 32f, which are the operation buttons 32 required for payment operations on the product sales data processing device 1.

Operation button 32a is a cash payment button for making payment for the products to be weighed with cash. Operation button 32b is a credit card payment button for making payment for the products to be weighed with a credit card. Operation button 32c is a subtotal discount button for the transaction. Operation button 32d is a subtotal price reduction button for the transaction. Operation button 32e is a cancel button for canceling the accounting screen (subtotal mode). Operation button 32f is a cancel button for canceling the subtotal discount and price reduction.

The payment types displayed in the third display area of the checkout screen are not limited to cash or credit card, but may also be electronic money or gift certificates. When canceling an item from the history display area 22 shown in the second display area 21, the store clerk touches, clicks, double-clicks, or otherwise operates the weight/quantity display area 24, product display area 25, or amount display area 26. This operation causes a strikethrough 30 or the like to be displayed on the line for an item such as tomatoes in the product registration list screen, allowing the item to be canceled. If the store clerk again touches, clicks, double-clicks, or otherwise operates the weight/quantity display area 24, product display area 25, or amount display area 26, the strikethrough 30 will disappear and the cancellation can be canceled.

If the customer's desired payment method is cash, the store clerk operates operation button 32a. If the customer's desired payment method is credit card, the store clerk operates operation button 32b. In this way, the transaction is completed by completing the payment using the customer's desired payment method.

As described above, according to this embodiment, the price tag only needs to have a barcode that can be read by the mobile terminal 200 that the store clerk holds on his finger, and a detection device that can detect contact is not required, making it possible to register products sold by weight at low cost. For example, the cost of a detection device increases in proportion to the number of products, but in this embodiment, the cost only involves the cost of the mobile terminal 200, and does not increase in proportion to the number of products.

Because the clerk identification information is stored in the mobile terminal 200 and the clerk identification information and product identification information are sent as a set to the product sales data processing device 1, the product sales data processing device 1 can link and manage the clerk identification information and product identification information. This means that even if multiple clerks read the barcodes on the price tags at the same time, the product sales data processing device 1 can manage the products for each clerk. This allows multiple clerks to work together, improving the productivity of the product sales data processing system.

In this embodiment, as described above, the product identification information and the store clerk identification information are transmitted from the mobile terminal 200, and the product sales data processing device 1 can receive them. An embodiment of the product sales data processing device 1 that uses this product identification information and store clerk identification information will be described.

First, an embodiment will be described in which the display mode of the product name, etc. is changed depending on the source of the product identification information. The product sales data processing device 1 can not only receive the product identification information acquired by the mobile terminal 200, but also acquire the product identification information using preset keys provided in the product sales data processing device 1. Furthermore, by providing the product sales data processing device 1 itself with a scanner that reads barcodes, the product identification information can also be acquired using the scanner. Note that the preset keys are different from the preset buttons that are displayed when product identification information is received from the mobile terminal 200.

In this way, when multiple sources of product identification information are assumed, the display mode of the product name, etc. displayed in the history display area 22 is changed depending on the source of the product identification information. FIG. 11 (A) is a diagram showing an example of the display color when changing the font color of the product name, as an example of changing the display mode. If the product identification information is obtained from the mobile terminal 200, the font color of the product name is set to blue. If the product identification information is obtained from a scanner, the font color of the product name is set to red. If the product identification information is obtained from a preset key, the font color of the product name is set to black.

By changing the display mode, the store clerk can recognize at a glance the source of the product identification information. In the example of FIG. 11(A), the font color of the product name is changed, but for example, the background color of the history display area 22 in which one product is displayed may be changed, the frame color may be changed, or the font may be changed.

In the example of FIG. 11(A), the display mode differs depending on the source of acquisition, but the display mode may also differ depending on the store clerk identification information.

Next, an embodiment in which a product identified by product identification information and related products are displayed will be described. Specifically, an embodiment in which a promotion is carried out to encourage related purchases according to product identification information will be described. FIG. 11(B) is a diagram showing related purchase data. The related purchase data is data stored in the product sales data processing device 1, but it may also be stored in another device such as a store controller and made available for acquisition by the product sales data processing device 1 as needed.

The related purchasing data is data that links the product indicated by the product identification information with related products. The related purchasing data consists of product name, category, recommended display 1, recommended display 2, price tag number, and price tag battery level. When the product sales data processing device 1 acquires product identification information, if the product name corresponding to the product identification information exists in the product names of the related purchasing data, it displays the product shown in recommended display 1 and 2. The reason that multiple recommended displays are provided, such as recommended display 1 and 2, is to accommodate cases where there is sufficient display area and cases where there is not. Recommended display 1 is displayed preferentially, and if there is sufficient area, recommended display 2 is displayed.

For example, if the product corresponding to the product identification information is chicken breast, fried chicken ingredients are displayed first, and if there is space, Bang Bang Chicken ingredients are also displayed. The display area may be, for example, the customer display unit 7 or the third display area 31 in the store clerk display and operation unit 6. When displayed on the customer display unit 7, a photo of the product may be displayed in addition to the product name. When displayed in the third display area 31, the store clerk will recommend the product to the customer.

In this way, related purchases can be encouraged, which can improve store sales. If the product name corresponding to the product identification information exists in the product name of the related purchase data, the scanning sound may be different, or a lamp or the like may be turned on to indicate that a recommendation is displayed.

The shelf tag number in the related purchase data is information for identifying the price tag 51 shown in FIG. 2 (B). In addition, the price tag battery remaining indicates the remaining battery charge of the price tag 51. In this way, by displaying the price tag number and the price tag battery remaining charge, the condition of the price tag, etc. can be confirmed, so the product sales data processing device 1 can not only increase sales through related purchases, but also support the smooth operation of the store.

Next, an embodiment will be described in which a predetermined process is performed for each store clerk indicated by the store clerk identification information. In the following, as the predetermined process, a process for changing the display mode of the store clerk display operation unit 6 for each store clerk will be described.

Figure 11 (C) is a diagram showing display mode data. The display mode data is data stored in the product sales data processing device 1, but it may also be stored in another device such as a store controller and made available for the product sales data processing device 1 to acquire as needed.

The display mode data is composed of store clerk identification information, scanner sound, button size, preset list, and linkable mobile terminal number. Scanner sound refers to the type of sound generated when a barcode is scanned. In this embodiment, four types of scan sounds are provided: A, B, C, and D. Button size refers to the size of buttons displayed on the store clerk display operation unit 6, such as preset buttons. In this embodiment, four types of button sizes are provided: extra large, large, medium, and small. The preset list indicates a list of functions assigned to preset keys. In this embodiment, four types of preset lists are provided: List 1, 2, 3, and 4.

The linkable mobile terminal number indicates the number of a mobile terminal that can be linked to the store clerk identification information. In the case of FIG. 11(C), for example, it is shown that a store clerk with store clerk identification information 1 can be linked to mobile terminals with mobile terminal numbers 01 and 04.

When the product sales data processing device 1 acquires the store clerk identification information, if the store clerk identification information exists in the display mode data, it acquires the scanner sound, button size, and preset list, and changes the display mode of the store clerk display operation unit 6 accordingly. For example, if the store clerk identification information is "1", the product sales data processing device 1 sets the type of scanner sound to A, sets the button size to small, and displays the preset keys to which the functions shown in list 1 are assigned.

By doing this, the display mode of the clerk display operation unit 6 can be changed depending on the clerk, so the display mode can be flexibly changed depending on the size of the clerk's fingers and their level of proficiency. This improves usability for the clerk, thereby improving the productivity of the product sales data processing device 1 and reducing operational errors.

Figure 11 (D) is a diagram showing terminal status data. The terminal status data is composed of linkable store clerk identification information, currently linked store clerk identification information, status, and remaining battery level for each mobile terminal number. The terminal status data is data stored in the product sales data processing device 1, but it may also be stored in another device such as a store controller and made available for the product sales data processing device 1 to acquire as needed.

The linkable clerk identification information indicates the clerk identification information of a clerk who can be linked with the mobile terminal corresponding to the mobile terminal number. The currently linked clerk identification information indicates the clerk identification information of the clerk who is currently linked with the mobile terminal corresponding to the mobile terminal number. The state indicates the state of the mobile terminal (on, off, charging). The remaining battery level indicates the remaining battery level of the mobile terminal. For example, in the case of Figure 11 (D), it is shown that the mobile terminal with mobile terminal number 01 can be linked with any of the clerks with clerk identification information 1, 2, or 3, is currently linked with the clerk with clerk identification information 1, the mobile terminal is powered on, and the remaining battery level is 80%.

The product sales data processing device 1 can display the display mode data described in FIG. 11(C) and the data contents of the terminal status data described in FIG. 11(D) on the store clerk display operation unit 6. Furthermore, the store clerk can add, delete, and update data in the display mode data and terminal status data in the product sales data processing device 1.

In the product sales data processing device 1, the store clerk can, for example, update the scanner sound, button size, preset list, and linkable mobile terminal number in the display mode data, delete data with clerk identification information of 1, and add data with clerk identification information of 6. Similarly, in the product sales data processing device 1, the store clerk can, for example, update the linkable clerk identification information and currently linked clerk identification information in the terminal status data, delete data with a mobile terminal number of 01, and add data with a mobile terminal number of 05.

By displaying the contents of the terminal status data by the product sales data processing device 1, the store clerk can check not only the status of the mobile terminal but also the attendance status of the linked store clerk through the status of the mobile terminal, etc., thereby allowing the store clerk to carry out work efficiently.

The process according to the embodiment described above will be described using a flowchart. FIG. 12 (A) is a flowchart showing the process of the mobile terminal 200. The control unit 210 of the mobile terminal 200 judges whether the reading unit 211 has read a barcode (step S101). If the reading unit 211 has read a barcode (step S101: YES), the control unit 210 transmits the store clerk identification information stored in the storage unit 212 and the product identification information acquired from the barcode to the product sales data processing device 1 via the communication unit 213 (step S102). The control unit 210 judges whether the switch 209 has been operated and turned off (step S103). If it has been turned off (step S103: YES), the control unit 210 ends the process. If it has not been turned off (step S103: NO), the control unit 210 returns to step S101.

Figure 12 (B) is a flowchart showing the process when the product sales data processing device 1 acquires the store clerk identification information. The control unit 111 of the product sales data processing device 1 acquires the store clerk identification information (step S201). The control unit 111 determines whether the acquired store clerk identification information exists in the display mode data (step S202). If the acquired store clerk identification information does not exist in the display mode data (step S202: NO), the control unit 111 ends the process. If the acquired store clerk identification information exists in the display mode data (step S202: YES), the control unit 111 acquires the scanner sound, button size, and preset list (step S203). The control unit 111 changes the acquired scanner sound, button size, and preset list, respectively (step S204), and ends the process.

Figure 12 (C) is a flowchart showing the processing when the product sales data processing device 1 acquires product identification information. The control unit 111 of the product sales data processing device 1 acquires product identification information (step S301). The control unit 111 determines whether or not a product name corresponding to the acquired store clerk identification information exists in the related purchasing data (step S302). If the product name does not exist in the related purchasing data (step S302: NO), the control unit 111 ends the processing. If the product name exists in the related purchasing data (step S302: YES), the control unit 111 acquires recommended products (step S303). The control unit 111 displays the acquired recommended products (step S304) and ends the processing.

In the embodiment described above, the mobile terminal 200 reads the barcode and communicates with the product sales data processing device 1, but this is not limited to the above. The device that reads the barcode and the device that communicates with the product sales data processing device 1 may be separate devices. In this case, for example, the device that communicates with the product sales data processing device 1 may be a wristband or glove-type device, and the device that reads the barcode communicates with the above device. Store clerk identification information in the device, and when the device receives product identification information from the device that reads the barcode, it transmits the received product identification information and the store clerk identification information stored in the device to the product sales data processing device 1.

When a conventional contact detection device is used together with the price tag described in the above embodiment, the detection device generally also has a barcode, so this embodiment can be applied as is by reading the barcode with the mobile terminal 200.

(Variation 1)
In the above-described embodiment, each time the mobile terminal 200 reads a barcode, the product identification information, etc. is transmitted to the product sales data processing device 1. In contrast, in the first modification, when the mobile terminal 200 reads a barcode, the product identification information, etc. is not transmitted to the product sales data processing device 1, but is temporarily stored in the storage unit 212 of the mobile terminal 200. Also, in the first modification, the product sales data processing device 1 refers to the terminal status data, and displays in the fourth display area 41 a clerk button 42 indicating a clerk associated with the mobile terminal 200 whose status is on.

The clerk reads the barcodes of all the products desired by the customer. The clerk then selects the clerk button representing the clerk himself/herself, which is displayed in the fourth display area 41 of the product sales data processing device 1. This establishes communication between the mobile terminal 200 and the product sales data processing device 1. The mobile terminal 200 transmits the product identification information temporarily stored in the memory unit 212 to the product sales data processing device 1. The product sales data processing device 1 displays the product selection button 28 corresponding to the received product identification information. The clerk then performs weighing, registration, settlement, etc., in the same manner as in the above-mentioned embodiment.

(Variation 2)
In the first modified example, the product sales data processing device 1 displays the clerk button 42, but instead of the clerk button 42, a code (barcode, two-dimensional code, etc.) that can be read by the mobile terminal 200 and that is used to establish communication between the mobile terminal 200 and the product sales data processing device 1 may be displayed. The clerk has the mobile terminal 200 read this code, and the mobile terminal 200 establishes communication with the product sales data processing device 1. After communication is established, the mobile terminal 200 transmits the product identification information temporarily stored in the storage unit 212 to the product sales data processing device 1, as in the first modified example. The product sales data processing device 1 displays the product selection button 28 corresponding to the received product identification information. After that, the clerk performs weighing, registration, settlement, etc., as in the above-mentioned embodiment.

The product sales data processing device 1 may be adapted to change the operation of the embodiment, including the above-mentioned variants 1 and 2, to suit the operating style of the store, etc.
