About the system.

  Conventionally, merchandise sales data processing devices such as POS terminals have been used for accounting operations at stores that sell merchandise or provide services. In the accounting process, a general merchandise sales data processing apparatus accepts input of a PLU (Price Look Up) code of a purchased merchandise by scanning a bar code attached to the merchandise, and stores merchandise information for the inputted PLU code as PLU. It is identified from the file, registered in the memory, sales information is created based on the product information registered during one transaction, and is transmitted to a host device such as a store server. In the host device, the sales data received from the merchandise sales data processing device is made into a database and used for inventory management and sales management.

  Some products do not have a PLU code assigned, and some do not have a barcode attached. In order to smoothly input product information of such products, there is also a product sales data processing apparatus that accepts input of product information using a so-called preset menu.

(Operation)
Next, operations of the store server 1 and the POS terminal 2 in the product sales system having the above-described configuration will be described.

[Preset menu change processing]
First, preset menu change processing for changing the display mode of the preset menu displayed on the display 47 of each POS terminal 2 will be described with reference to the flowchart shown in FIG. This process is realized by the CPU 10 of the store server 1 executing the operation program stored in the ROM 11 and the CPU 30 of each POS terminal 2 executing the operation program stored in the ROM 31.

  While the merchandise sales system is operating, the CPU 10 of the store server 1 waits for the delivery timing of the weighting table 23 to arrive (step S101). Whether or not the delivery timing has arrived is determined by, for example, measuring the elapsed time from when the previous weighting table 23 was delivered to each POS terminal 2 by the clock circuit 13, and the elapsed time stored in the ROM 11 or the HDD 17. Judgment based on whether or not. Alternatively, the determination may be made based on whether or not the time counted by the clock circuit 13 has reached a predetermined time. However, in order to distribute the latest weighting table 23 as much as possible to each POS terminal 2, it is desirable to set a short distribution timing within a range that does not hinder system operation.

  If it is determined that the distribution timing has arrived (step S102), the CPU 10 of the store server 1 stores the product information in each operation key in the preset table 22 based on the product information in the sales information registered in the sales database 21. The number of sales of products to which is assigned is tabulated (step S102). At this time, all the sales information registered in the sales database 21 may be the target of aggregation. For example, the sales information for a specific period from the time when the previous weighting table 23 was distributed to each POS terminal 2 to the present is the target of aggregation. It is good.

  After totaling the number of sales of all products for which product information is assigned to the operation keys in this way, the CPU 10 of the store server 1 updates the weighting values in the weighting table 23 stored in the HDD 17 using the totalization results. (Step S103). Specifically, a weighting value corresponding to the number of sales as a result of aggregation is selected for the products associated with the type of each operation key in the preset table 22, and the type of the operation key in the weighting table 23 stored in the HDD 17. Update the weight value associated with. At that time, for example, a sales number category may be provided for each weighting value, and a weighting value may be selected according to a category to which the sales number as a result of aggregation belongs. A rate may be calculated, and a weighting value may be selected according to the category to which the occupation rate belongs.

  After updating the weighting table 23 in this way, the CPU 10 of the store server 1 distributes the weighting table 23 stored in the HDD 17 to each POS terminal 2 via the communication I / F 14 and the LAN 3 (step S104). ).

  The CPU 30 of each POS terminal 2 waits for reception of the weighting table 23 distributed from the store server 1 in parallel with other processing such as accounting processing (step S105). If the weighting table 23 distributed as described above is received via the LAN 3 and the communication I / F 34 (Yes in step S105), the CPU 30 stores the weighting table stored in the HDD 35 in the received weighting table 23. 23 is updated (step S106).

  Thereafter, the CPU 30 of the POS terminal 2 creates preset menu display data to be displayed on the display 47 in the working storage area of the RAM 32 (step S107). Specifically, the product information assigned to the type of each operation key is specified with reference to the preset table 22 stored in the HDD 35 and added to each key pattern in the display data. Furthermore, the weighting value registered in the weighting table 23 stored in the HDD 35 in association with the type of each operation key is specified, and the coloring, size, and key pattern of the key pattern registered in the key pattern table 24 in association with the specified weighting value. The display mode of each operation key in the display data is changed based on one of the patterns or a combination thereof.

  When the display data of the preset menu has been created, the CPU 30 of the POS terminal 2 outputs the display data to the display controller 39 and displays it on the LCD panel 48 (step S108). Thus, the preset menu displayed on the display 47 of each POS terminal 2 is updated to reflect the contents of the latest preset table 23 distributed from the store server 1.

  The preset table 22 and the key pattern table 24 are distributed from the store server 1 to each POS terminal 2 with a period longer than the timing at which the weighting table 23 is distributed, such as at the start or end of a day's work. The

An example of the preset menu displayed on the display 47 through the processing of steps S101 to S108 is shown in FIGS. Each figure shows that the operation keys K1, K3, K4, and K11 are obtained as a result of the weighting value for each key type being selected from W1 (low), W2 (normal), and W3 (good) in the process of step S103. W1 is selected as the weighting value to be assigned to the operation key W2, W2 is selected as the weighting value to be assigned to the operation keys K2, K5, K7, K10, and K12, and W3 is selected as the weighting value to be assigned to the operation keys K6, K8, and K9. This is an example. Colors, sizes, and patterns for the weight values W1 to W3 are those registered in the key pattern table 24 shown in FIG.
FIG. 9 is an example in which the display mode of each operation key in the preset menu is changed by using the information regarding the color registered in the key pattern table 24. The coloring of operation keys K1, K3, K4, and K11 is changed to color 1 (default) assigned to weighting value W1, and the coloring of operation keys K2, K5, K7, K10, and K12 is assigned to weighting value W2. The color of the operation keys K6, K8, and K9 is changed to the color 3 assigned to the weighting value W3. Note that color 2 is a color emphasized so as to be more visually appealing than color 1, and color 3 is a color emphasized so that it is easier to appeal visually than color 2. Therefore, the operation keys K6, K8, and K9, which are operation keys related to products that are selling well, are easy to see at a glance, and then the operation keys K2, K5, K7, K10, which are operation keys related to products that are sold well. K12 is easily noticeable.

  FIG. 10 shows an example in which the display mode of each operation key in the preset menu is changed using the information regarding the size registered in the key pattern table 24. The size of the operation keys K1, K3, K4, and K11 is changed to the small size assigned to the weighting value W1, and the size of the operation keys K2, K5, K7, K10, and K12 is the medium size assigned to the weighting value W2. (Default), and the size of the operation keys K6, K8, and K9 is changed to the large size assigned to the weighting value W3. As a result, the operation keys K6, K8, and K9, which are operation keys related to products that are selling well, are easy to see at a glance, and then the operation keys K2, K5, K7, and K10 are operation keys related to products that are sold well. , K12 is easily noticeable.

  FIG. 11 shows an example in which the display mode of each operation key in the preset menu is changed using information on the pattern registered in the key pattern table 24. The patterns of the operation keys K1, K3, K4, and K11 are changed to the pattern 2 assigned to the weight value W1, and the patterns of the operation keys K2, K5, K7, K10, and K12 are the pattern 1 assigned to the weight value W2. Since no pattern is registered in the weighting value W3, the operation keys K6, K8, and K9 are not provided with a pattern. The pattern 1 is an image obtained by slightly degrading the key pattern, and the pattern 2 is an image obtained by further degrading the key pattern as compared with the pattern 1. Therefore, the operation keys K 1, K 3, K 4, and K 11 related to products with these patterns, particularly those related to products with low sales, give an impression that they cannot be selected at first glance, and the operation keys related to products with good sales. K6, K8, and K9 are easily noticeable.

[Sales information registration process]
Next, sales information registration processing for registering sales information related to products sold at each POS terminal 2 in the sales database 21 stored in the HDD 17 of the store server 1 will be described with reference to the flowchart of FIG. This process is realized by the CPU 10 of the store server 1 executing the operation program stored in the ROM 11 and the CPU 30 of each POS terminal 2 executing the operation program stored in the ROM 31.

  The CPU 30 of each POS terminal 2 shifts to a state of accepting registration of product information in response to the depression of the PLU key provided on the keyboard 44 (steps S201 and S202). At this time, the product information of the purchased product can be input by reading the barcode attached to the product or its packaging by the vertical scanner 51, or by touching the preset menu displayed on the display 47. . When the vertical scanner 51 reads the barcode, the PLU code of the product is input, and the store server 1 is inquired about the product information for the input PLU code. At this time, the store server 1 searches the PLU file stored in the HDD 17 for product information for the PLU code, and returns the found product information to the POS terminal 2 that is the inquiry source. On the other hand, when the preset menu screen is touched, the product information registered in the preset table 22 of the HDD 35 in association with the type of the operation key arranged at the touch operation position of the touch panel 49 is input. The input product information is registered in the work storage area for product information registration generated in the RAM 32.

  When the input of product information for all the purchased products is completed, the cashier depresses a subtotal key provided on the keyboard 44. When detecting that the subtotal key is pressed, the CPU 30 of the POS terminal 2 determines that the input of the merchandise information is completed (Yes in step S202), calculates the total amount of the transaction, and displays the display 47 and the customer side. The state is displayed on the display 50 and shifts to a state of accepting payment (steps S203 and S204). At this time, the CPU 30 processes the payment of the price by a known procedure using cash, credit card, electronic money or the like. When the price is thus paid, the CPU 30 drives the receipt printer 46 via the printer controller 38 to issue a receipt on which the detailed information of the transaction is printed (step S205). Further, the CPU 30 transmits the sales information including the product information registered in the work storage area for product information registration in the RAM 32 to the store server 1 via the communication I / F 34 and the LAN 3 (step S206), The accounting process is terminated.

On the other hand, the CPU 10 of the store server 1 waits for reception of sales information transmitted from each POS terminal 2 while the system is operating (step S207). If the sales information transmitted from one of the POS terminals 2 in the process of step S206 is received via the LAN 3 and the communication I / F 14 (Yes in step S207), the CPU 10 receives the received sales information. Is registered in the sales database 21 stored in the HDD 17 (step S208), and a series of processing ends.
Thus, the sales information registered in the sales database 21 is used when selecting a weight value to be assigned to each operation key in the next preset menu update process.

  As described above, the POS terminal 2 used in the product sales system in the present embodiment receives the weight value assigned to each operation key constituting the preset menu from the store server 1 according to the sales of the product, The display mode of the operation key displayed on the display 47 is changed based on the received weight value. In this way, the display mode of the preset menu can be changed to accurately reflect the sales of products that change according to the day of the week and the time of day, so that even beginners can easily find operation keys that are frequently used. it can. In other words, it is possible to greatly improve the operability of the preset menu and facilitate the accounting process in consideration of the special business content of the accounting process.

  Further, when product information is input via a preset menu and a customer's purchased product is sold, sales information including the product information is transmitted from the POS terminal 2 to the store server 1. By using the sales information transmitted from the POS terminal 2 in this way, the store server 1 can select a weighting value that accurately reflects changes in sales of products. In particular, in a merchandise sales system having a plurality of POS terminals 2 as in the present embodiment, weight values reflecting the sales as a whole store can be selected instead of each POS terminal 2 alone, so that a remarkable effect can be obtained. Play.

  In addition, the display mode of each operation key is changed by changing at least one of the color, size, and pattern of the operation keys constituting the preset menu according to the weight value. Even when any of these colors, sizes, and patterns is changed, it is possible to make an operation key highly likely to be selected according to the sales of the product indicated by the product information assigned to the operation key.

  Note that the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage.

  For example, in the above-described embodiment, the example in which the present invention is applied to the POS terminal 2 including the main body 5 and the product information input unit 6 has been described. However, the present invention may be applied to a merchandise sales data processing apparatus in which the merchandise information input unit 6 is not provided and the main body 5 itself has a function of inputting merchandise information. In this case, the preset menu is displayed on a display with a touch panel provided in the main body of the merchandise sales data processing device, and the display mode of the operation keys constituting the preset menu is changed as disclosed in the above embodiment. You can do it.

  In the embodiment, the example in which the store server 1 is used as a host device connected to each POS terminal 2 has been described. However, a server device that comprehensively manages sales information of a plurality of stores may be employed as the host device. In this case, the weighting value can be selected by extending the sample matrix to sales information of a plurality of stores, which is efficient.

  In the embodiment, the case has been described in which the color, size, and pattern of the operation keys constituting the preset menu are changed. However, the display mode may be changed using other methods such as changing the transparency of the operation keys. Furthermore, the coloring, size, and pattern may be changed in multiple stages as disclosed in the embodiment, or may be changed in only two stages.
