Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electronic cash register (hereinafter referred to as ECR), and particularly to an ECR that performs registration processing using an IC card.

[Prior Art] Some conventional ECHs store a PLU file in a card in advance and perform registration processing using the card. Here, the PLU file includes the product identification code,
This is a file that stores unit price information of the product corresponding to the code. Furthermore, the function of reading out and registering the unit price of a product stored in a PLU file by simply inputting the code when selling a product is called the PLU function.

[Problems to be solved by the invention] By the way, some products have selling prices that change depending on the time of day or date. However, with conventional ECR, only a single unit price information is stored for each product.
For products whose prices are to be changed, price data must be entered from the keyboard, which is a problem.

Therefore, this invention was made to solve the above-mentioned problems, and it provides an ECR that allows registration processing using a card and simply by inputting a code for products with different prices depending on the time of day or date. The purpose is to provide.

[Means for solving the problems] This invention is an ECR that performs registration processing using an IC card.
The IC card includes at least a file in which data regarding the time zone or date of the product is stored in advance for each product, and a clock means for timing the current time or date, and further includes input of product identification data. a registration means for registering data regarding the product; and a registration means for reading data regarding the product at the current time or date measured by the clocking means from the file each time product identification data is input from the input means. and a control means for controlling the registration process according to the following.

[Operation] In this invention, each time a product identification code is input, the data regarding the product at the current time or date is read from the file and registered, so the operator does not need to input amount data.

[Embodiment] FIG. 2 is a diagram showing a schematic configuration of an ECR according to an embodiment of the present invention. In FIG. 2, an ECR main body 1 is provided with at least a card reader/writer 2, a keyboard 3, and a display 4. An IC card 5 is inserted into the card reader/writer 2 when performing registration processing. This IC card 5 contains a PLU file and a timer which will be explained later in FIG. The PLU file stores sales price data on the time zone or date side for each product. The keyboard 3 is used to input product identification data, such as a PLU code. The display 4 displays product name data, sales price data, etc. read from the IC card 5.

FIG. 1 is a schematic block diagram showing the electrical configuration of an ECR according to an embodiment of the present invention. In FIG. 1, an ECR main body 1 is provided with a CPU 6. As shown in FIG. The CPU 6 includes the above-mentioned card reader/writer 2. In addition to the keyboard 3 and display 4, there is also a printer 7, a cash drawer 8. ROM9 and R

The printer 7 prints transaction details on receipt paper. The cash drawer 8 is for storing cash. The ROM 9 stores an operating program for the CPU 6 based on a flowchart as shown in FIG. 4, which will be explained later. The RAM 10 stores data input from the keyboard 3, data read by the card reader/writer 2, and the like.

The IC card 5 is provided with a CPUI 1.

CPUI 1 has an input/output port 12, a timer 13, and an R
OM14 and RAM15 are connected. When the IC card 5 is inserted into the card reader/writer 2, the card reader/writer 2 and the human output port 12 are electrically connected, and power and data are transmitted via the input/output port 12.
It is supplied to the C card 5. The timer 13 measures the current date and time. The ROM 14 stores an operating program for the CPU 1 as shown in FIG. 5, which will be explained later. The RAM 15 stores a PLU file as shown in FIG. 3, which will be explained later, and when power is not universally supplied through the input/output port 12, power is supplied from the bank-up power supply 16.
Retains memory contents.

FIG. 3 is an illustrative diagram showing the storage area of the RAM 15 of the IC card 5 shown in FIG. In Figure 3, RAM
15 is composed of a card number storage area 18, a password code storage area 19, and a PLU file 20.

Card number data of the IC card 5 is stored in the card number storage area 18. PIN code storage area 1
9 stores the password code of the customer who owns the IC card 5. The PLU file 20 consists of areas 21a, 21b, 21c, etc. for each product. Each of the areas 21a to 21c for each product is the PLU code sanbetsu area 2.
2, a PLU code storage area 23, a product name data storage area 24, a sales price data storage area 25, a sales quantity data storage area 26, and a time or date data storage area 27.

The PLU code identification area 22 contains a code for identifying whether the price of the product is fixed, changes depending on the time of day, or changes depending on the date. Identification data is stored. Here, if this identification data is, for example, O, it indicates that the price is fixed, if it is, for example, 1, it indicates that the price changes depending on the time of day, and if, for example, 3, it indicates that the price changes depending on the date. The PLU code storage area 23 stores a PLU code as product identification data. The product name data storage area 24 stores product name data of the product.

The sales price data storage area 25 stores the sales price data of the product. The sales quantity data storage area 26 stores the sales quantity data of the product. The time or date data storage area 27 stores data indicating the time or date at which the price is changed. In this example, as shown in Figure 3, for example, the selling price of plum kombucha is fixed at 380 yen, but the selling price of white bread is 800 yen.
before that time, it is 200 yen, and from 8:00 to 17:00 it is 260 yen.
The price will change to 150 yen after 5pm.

In addition, the selling price of toothpaste is 300 yen until July 27th, 200 yen from July 21st to August 29th, and 800 yen from July 21st to August 29th.
After the 29th of the month, the price will be changed to 300 yen.

FIG. 4 is a flow diagram for explaining the operation of the ECR main body 1 shown in FIG. Next, the operation of the ECR main body will be explained with reference to FIGS. 1 to 4.

The CPU 6 of the ECR body 1 waits until the staff key is operated, and when the staff sets the IC card 5 in the card reader/writer 2 and operates the staff key, the CPU 6 of the ECR main body 1 waits until the next time the key is powered. .

If the staff member does not operate the PLU key,
The process corresponding to each key is performed, but if the staff enters the PLU code and then operates the PLU key, the IC
The PLU code and number data are sent to the card 5.

The IC card 5 operates based on an operation program based on the flowchart shown in FIG. However, if there is no corresponding PLU code, a message indicating that there is no PLU code is sent. Accordingly, CPU6
If there is no U code, display the message "No applicable PLU code" on the display 4, and then wait until the key is pressed, or if there is an applicable PLU code, insert the IC card. The product name data and unit price data are read from the printer 5, and the product name data and unit price data are printed by the printer 7, and these data are displayed on the display 4. The above operations are performed for all products purchased by the customer.

FIG. 5 is a flow diagram for explaining the operation of the IC card shown in FIG. 1. Next, the operation of the IC card will be explained with reference to FIGS. 1 to 5. The CPU II of the IC card waits until the PLU code is received via the input/output port 12, and when the PLU code is received, it searches the PLU file 20 stored in the RAM 15. If there is no corresponding PLU code in the PLU file 20, the EC indicates that there is no corresponding PLU code.
Reply to R body 1 and if there is a corresponding PLU code,
Based on the identification data in the PLU code identification area 22 of the product, it is determined whether the price is fixed or not. Here, if the product is, for example, plum kombucha, the price is fixed, so next, the sales quantity data storage area 26a is updated by the number of units sold, and the product name data, for example, plum kombucha, and the price data, for example, 380, are stored in the ECR. Send to main unit 1.

On the other hand, if the price is not a fixed price, it is determined whether the price is a time-of-day variable price that changes depending on the time of day. Here, when the price changes depending on the time of day, as in the case of white bread shown in FIG. 3, the current time data is read from the timer 13,
Request sales price data. Further, when the price changes depending on the date, as in the case of toothpaste shown in FIG. 3, the current date data provided by the timer 13 is read to obtain the sales price data of the product. Subsequently, the sales quantity data of the product is updated by the number of sales, and the product name data and sales price data of the product are sent to the ECR main body 1. If the number of items sold is two or more, sales amount data obtained by multiplying the unit price of the item by the number of items may be sent to the ECR main body 1. The above operation is performed every time a PLU code is given from the ECR main body 1.

[Effects of the Invention] As described above, according to the present invention, each time a product identification code is input, data related to the product at the current time or date of the product is read from a file and registration processing is performed. Since the operator does not have to input amount data, the registration process can be performed efficiently.
