  The POS control unit 57 realizes functions to be described later when the CPU operates according to a computer program stored in a hard disk drive (HDD) 62.

  Next, various processes executed by the shopping system will be described together with various setting procedures.

  First, the parent-child setting process of the shopping basket 11 executed by the basket control unit 16 of the shopping basket 11 according to the computer program will be described along with the setting procedure based on the flowchart shown in FIG.

  First, the customer first selects one shopping basket 11 and operates the relative declaration button 24a displayed on the initial screen G1 of the display 14 in order to set the shopping basket 11 as a parent. As shown in FIG. 6, when it is determined that the relative declaration button 24a has been operated and the relative 11a declaration has been made (Y in step S1), the saddle control unit 16 adds the corresponding parent / child type area 23a of the setting table T1. The shopping basket 11 stores the fact that it is a parent, and sets the shopping basket 11 as a relative 11a (step S2). Here, the function of the parent setting means is executed in steps S1 and S2.

  Next, the customer secondly selects a shopping basket 11 other than the relatives 11a, and brings the selected shopping basket 11 and relatives 11a close to a distance that enables information communication using infrared rays between them. The child selection button 24b on the initial screen G1 of the shopping basket 11 selected second is operated. Then, if the basket control unit 16 of the shopping basket 11 determines that the child declaration button 24b is operated and the child declaration is made (Y in Step S3), the shopping basket 11 is stored in the parent-child type area 23a of the setting table T1. Is stored as a child and the shopping basket 11 is set as the child basket 11b (step S4). Here, the function of the child setting means is executed in steps S3 and S4.

  Then, after setting itself as the relative 11a or the child 11b, the parent-child relationship setting process (parent version or child version) is executed (steps S5a, S5b, association means). This process starts earlier for the child lion 11b than for the relative 11a. Specifically, when the child rabbit 11b is set, after executing steps S3 and S4, the infrared communication apparatus 20 continuously transmits the baby rabbit 11b's basket number to the relative 11a. As described above, these relatives 11a and child 11b are close to the range where infrared communication is possible, so mutual information communication using infrared rays is performed. On the other hand, the process in the case of being set in the relative 11a receives the serial number transmitted from the secondary serial 11b, stores the received serial number in the related personal area 23b of the setting table T1, and the child of the serial number It is set that the bag 11b is a child of the relative 11a. Thereafter, the relative 11a transmits the serial number of the relative 11a to the child 11b. Then, in the child 11b that has received the relative number of the relative 11a, the received relative number of the relative 11a is stored in the related relative area 23b of the setting table T1, and the relative 11a is associated with the child relative 11b. Set as parent. Thereby, the relatives 11a and the child 11b are associated with each other. Note that the number of child limbs 11b associated with one relative 11a may be single or plural.

  Next, in the puppet 11b set as a child, the screen display of the display 14 is switched to the puppet screen G2 shown in FIG. 7 (step S6). The puppet screen G2 is a screen on which only the budget amount area 24g, the pod total amount area 24j, the pod product information area 24k, and the total amount area 24l are displayed on the initial screen G1. Note that the initial screen G1 is continuously displayed on the display 14 of the relative 11a.

  Next, a budget amount setting process for setting a budget amount for shopping will be described together with a setting procedure based on the flowchart shown in FIG. This budget amount setting process is a process executed only in the shopping basket 11 set as the relative 11a. Moreover, it is not ask | required whether the child 11b is set with respect to the relative 11a at this time. The customer first operates the budget amount setting button 24f displayed on the initial screen G1 of the relative 11a. If the bag control unit 16 of the relative 11a determines that the budget amount setting button 24f is set (Y in step S11), the shopping basket 11 is the relative 11a (Y in step S12). A budget amount setting screen G3 as shown in FIG. 9 is displayed on the display unit 14 (step S13). On the budget amount setting screen G3, a budget amount area 71a, numeric keys 71b of “0” to “9”, a confirmation button 71c, a clear button 71d, and the like are displayed. The customer inputs the budget amount using the numeric keys 71b. As a result, the budget amount is displayed in the budget amount area 71a. Then, the customer operates the confirmation button 71c. Thereby, the budget amount is input to the bag control unit 16. The clear button 71d is a button for clearing the budget amount displayed in the budget amount area 71a.

  When it is determined that the budget amount has been input (Y in step S14), the control unit 16 sets the budget amount by storing the input budget amount in the budget amount area 23c of the setting table T1 (step S14). S15). Here, the function of the budget setting means is executed in steps S11 to S15.

  Next, the shopping support process will be described based on the flowchart shown in FIG. In the shopping support process, generally, the total amount of the products stored in the related relatives 11a and 11b is totaled every fixed time before the settlement, and the total amount is set. When the budget amount is exceeded, this is a process for notifying that effect.

  Specifically, first, in the child candy 11b, the wireless tag reader / writer 19 receives the product codes of all the products stored in the child candy 11b, stores them in the product file F2 in the candy and obtains them (step S21). . Then, the product master file F1 is searched based on the acquired product code, product information (product name, unit price, etc.) is acquired, the total price of those products is calculated (step S22), the total price, product information, Are displayed in the total amount area 24j and the child merchandise information area 24k (step S23). Then, the acquired product code is transmitted to the relative 11a associated with the setting table T1 in association with the serial number of the child 11b using the wireless communication device 21 (step S24). Thus, in the present embodiment, the product code is stored in the relative 11a as information necessary for calculating the total amount of the prices of all the products stored in the associated relative 11a and the child 11b. Collected. This process is repeated at regular intervals until the settlement process is declared (Y in step S25). Thereby, the information regarding the child lion 11b is updated at any time. The settlement process declaration will be described later in the settlement process.

  Next, also in the relative 11a, first, similarly to the child ridge 11b, the wireless tag reader / writer 19 receives the product codes of all the products stored in the relative 11a, stores them in the in-cassette product file F2, and acquires them. (Step S31). Then, the product master file F1 is searched based on the acquired product code, product information (product name, unit price, etc.) is acquired, the total price of those products is calculated (step S32), the total price, product information, Are displayed in the relative total amount area 24h and the relative merchandise information area 24i (step S33). Then, the commodity code of the commodity stored in the small child 11b transmitted from the small child 11b associated with the relative 11a is received and stored in the commodity file F2 in the basket for each small child 11b (step). S34). Then, the product master file F1 is searched based on the product code of the product in the acquired child lion 11b, product information (product name, unit price, etc.) is acquired, and the total price of those products is calculated (step S35), The total price and product information are displayed in the total price area 24j and the secondary merchandise information area 24k (step S36). At this time, when there are a plurality of associated child pods 11b, the information of the child lion 11b having the smallest pod number is displayed in the pod total amount area 24j and the pod commodity information area 24k. Then, the total amount of all the products stored in the related relatives 11a and 11b is added to the total amount of the relatives 11a and the total amount of the relatives 11b associated with the relatives 11a. Is calculated (step S37), stored in the product file F2 in the bag, and displayed in the total amount area 24l of the initial screen G1 (step S38). Here, the function of the total amount calculating means is executed by steps S21 to S25 and steps S31 to S37. Further, the function of the amount notifying means is executed in step S38. Furthermore, the function of the storage means is executed by steps S21 to S24 and steps S31 to S34.

  Next, it is determined whether or not the calculated total amount exceeds the budget amount set in the setting table T1 (step S39, determination means). If the total amount of the product does not exceed the budget amount (N in step S39), the process proceeds to step S40. On the other hand, if it is determined that the total price of the product has exceeded the budget price (Y in step S39), the buzzer 18 is sounded to notify the customer that the total price of the product has exceeded the budget price (step S41). , Budget overage reporting means). Thereafter, the process proceeds to step S40. This process is repeated at regular intervals until the settlement process is declared (Y in step S40). As a result, various information (such as the total amount) in the relative 11a is updated as needed.

  Next, the settlement process will be described based on the flowchart shown in FIG. In addition, the flowchart of FIG. 10 is also referred to as needed. At the time of payment, the cashier performs a reading input operation by the barcode scanner 56 on the barcode number assigned to the basket body 12 of the relative 11a. When the POS control unit 57 of the POS terminal 51 determines that the bar code number assigned to the main body 12 of the relative 11a is read and input by the bar code scanner 56 (step S51), the settlement starts. Is declared (step S52). Specifically, a settlement start declaration is transmitted using the POS wireless communication device 60 to the relative 11a of the input serial number.

  On the other hand, if the saddle control unit 16 of the relative 11a receives the settlement start declaration by the wireless communication device 21 and determines that the settlement start declaration has been made (Y in step S40, see FIG. 10), the associated child The settlement start declaration is transferred to the wireless communication apparatus 21 with respect to 11b (step S61). The kite control unit 16 of the child kit 11b that has received the settlement start declaration by the wireless communication device 21 acquires the product code of the product currently stored in the kite 11b by the radio tag reader / writer 19, and the above-described child kit 11b information. And the acquired product code is transmitted to the related relative 11a (step S71). Then, the relative 11a acquires the product code transmitted from the child 11b, updates the information related to the child 11b in the same or the same manner as described above, and the product currently stored in the relative 11a. Is acquired by the wireless tag reader / writer 19 to update the information related to the relative 11a, and the product code of the product stored in the current relative 11a and child 11b is transmitted to the POS terminal 51 by the wireless communication device 21. (Step S62).

  In addition, in order to prevent the replacement of the product for the shopping basket 11 after the settlement declaration is made, when the settlement start declaration is made, the product information of the relative 11a and the child 11b stored in the in-casket product file F2 is fixed. The product code of the product in the shopping basket 11 is acquired and stored temporarily in the RAM at regular intervals even after the settlement start declaration, and the product code and the product file stored in the RAM are stored in the RAM. Compare with the product code fixedly stored in F2, and if they are different, it is determined that the product has been replaced for the shopping basket 11 after the settlement start declaration, and the buzzer 18 is sounded to warn Good.

  The POS terminal 51 that has received the product codes of all the products stored in the relative 11a and the relative 11b from the relative 11a executes a sales process (step S53). Specifically, the product master file F3 is searched based on the received product code, the product name, unit price, etc. corresponding to the corresponding product code are read out, the total amount is calculated, displayed on the display 55, or by the printer 61. A receipt is issued and sales data is accumulated in the sales file F4.

  The cashier operates the reset button 24c displayed on the initial screen G1 of the relative 11a when finishing the settlement. The relative 11a for whom the reset button 24c has been operated (Y in step S63) transmits a message to that effect to the associated child 11b (step S64). Then, in the relatives 11a and the small child 11b, the information stored in the in-cassette product file F2 and the information stored in the setting table T1 is cleared (step S65 and step S72). As a result, the parent-child relationship is canceled and the product information is deleted. Here, the function of the release means is executed in steps S63 to S65 and step S72.

  As described above, in the present embodiment, the relative 11a and the child 11b are associated with each other, information communication is performed between the associated relative 11a and the child 11b, and the relative 11a. The total amount of the price of all the products stored in the child 11b is calculated based on the product code which is the price information acquired by the wireless tag reader / writer, and the total amount is displayed on the display 14 to the customer. Therefore, even when the customer uses a plurality of shopping baskets 11 for shopping, the customer can easily grasp the total amount of products to be purchased.

  Further, in the present embodiment, a parent setting means for setting a certain shopping basket among a plurality of shopping carts 11 as a parent and a shopping basket among the plurality of shopping baskets 11 are set as children. By providing the child setting means, any shopping basket 11 can be set as a parent or a child.

  Further, in the present embodiment, a budget setting means for setting a shopping budget amount, a determination means for determining whether or not the calculated total amount exceeds the set budget amount, and a calculated total amount When the total amount exceeds the set budget amount, the customer can easily perform planned product purchase by providing budget excess notification means for notifying the fact.

  In the present embodiment, the price information includes product specifying information for specifying the product, and is associated with the nonvolatile memory 22 that is a storage unit provided in the relative 11a that is the parent carrier. The product codes, which are the product identification information of all products stored in the relatives 11a and the secondary carriers 11b, are collected in the relatives 11a by using the wireless communication device 21 as wireless communication means and stored in the nonvolatile memory 22. By storing the storage means to be stored and the POS terminal 51 which is a payment processing means for executing the product payment processing based on the product code stored in the non-volatile memory 22, Since the POS terminal 51 performs checkout processing using the product codes of all products held in the non-volatile memory 22 of the relative 11a, the cashier must perform a scanning operation for each product. Since it is not, it is easy to settlement work.

  Moreover, in this Embodiment, it is the merchandise specific information memorize | stored in the non-volatile memory 22 which is a memory | storage part, canceling | releasing association with the relatives 11a which is a parent carrier, and the child cage 11b which is a child carrier. By providing the release means for clearing the product code, it is possible to repeatedly use the relative and the child in association with each other.

  Moreover, in this Embodiment, a alerting | reporting part can be easily implement | achieved by the alerting | reporting part being the indicator 14 which displays information.

  In the present embodiment, the shopping basket 11 is described as an example of the transport body, but the transport body is not limited to this and may be a shopping cart.

  Further, although the POS terminal 51 has been described as an example of the settlement processing unit, the settlement processing unit is not limited to this, and may be, for example, an ECR (Electronic Cash Register).

  Further, the product code is described as an example of the price information for specifying the price of the product, but the price information is not limited to this, and may be the price of the product itself, for example.

  Further, in the shopping support process, as information necessary for calculating the total amount of the prices of all the products stored in the related relatives 11a and the child's 11b, the product code is taken as an example, and this product code is used as the information. Although it collected in relative 11a, it is not restricted to this. For example, the price of the product is acquired based on the product code in the child ridge 11b, and the price of the acquired product is used as information necessary for calculating the total amount, which is transmitted to the relative 11a to the relative 11a. May be collected.

  Moreover, although the example which sets the shopping basket 11 arbitrarily selected from the some shopping basket 11 as the relative 11a and the child 11b was demonstrated as the setting method of the relative 11a and the child 11b, it does not restrict to this Absent. For example, a shopping basket 11 set in advance as a relative 11a and a shopping basket 11 set in advance as a child 11b may be prepared. In this case, the customer only has to select the relatives 11a and the child 12b and then associate them.

  Further, the method for associating the relative 11a with the child 11b is not limited to the method described in steps S5a and S5b of the parent / child setting process. For example, when the relative declaration button 24a is operated on the initial screen G1 of the relative 11a, the display 14 displays a child setting screen (not shown). A keyboard is displayed on the child-career setting screen, and it is possible to input the basket number of the shopping basket 11 set in the child-care product 11b. Then, if the number of the shopping basket 11 to be set to the child basket 11b is input on this child basket setting screen, information indicating that the parent-child relationship is set from the relative 11a is transmitted to the shopping basket 11 of that basket number. To do. This transmission is performed by the wireless communication device 21, for example. Then, the parent-child relationship setting process is executed in both the relative 11a and the child 11b.
