Description

[Detailed Description of the Invention] (Technical Field) This invention relates to a control method for an electronic cash register,
In particular, it relates to a control method for an electronic cash register with a price lookup function.

(Prior art) The conventional electronic cash register is a terminal controller.
In cluster systems connected to 2, price lookups were performed using files on electronic cash registers or files on terminal controllers. However, when using files on electronic cash registers, multiple electronic cash registers are
Having a large file individually makes it unnecessarily large, and if the file exists in the terminal controller, multiple electronic cash registers share one file, which increases the amount of time spent on price lookups. It had some drawbacks.

OBJECTS OF THE INVENTION It is an object of the present invention to eliminate the drawbacks of conventional electronic cash registers and to allow the terminal controller to contain a file of all the information needed by the system, and to provide an electronic cash register for the terminal controller. It is an object of the present invention to provide a control method for an electronic cage register that can improve cost and processing speed by allowing a portion of a file to exist. Another object of the present invention is to provide a control method for an electronic cash register that makes it possible to prevent file destruction even if the electronic cash register goes down by using non-volatile memory in the storage device of the electronic cash register. It is about providing.

(Structure of the Invention) According to the present invention, in a control method for an electronic carriage breath register that is connected to a terminal controller to perform data communication, the terminal controller has a main price lookup file, and the electronic carriage breath register has a sub-base price lookup file. A control method for an electronic cash register having a price lookup file, having means for accessing the main or sub-price lookup file depending on the frequency of use, and means for generating a sub-price lookup file when the frequency of use is high is provided. can get.

(Example) Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 shows a system configuration in an embodiment of the present invention. In FIG. 1, this embodiment has a system configuration in which one or more terminal controllers (TC) 10 are connected to a plurality of electronic cash registers (POS) 21 to 2n, and the electronic cash register is controlled. Including methods. FIG. 2 shows the electronic cage breath register in this embodiment. In FIG. 2, this electronic cash register (POS) 20 is connected to a central processing unit (CPU) 31.

)13. l Non-volatile memo for use in in-breasted files +714. It is comprised of a price lookup (PLU) control unit 15 that determines the PLU function and frequency of use and generates a sub-price lookup file. In this embodiment, a terminal controller 10 and an electronic cash register 21 which is a terminal device are used.
This is an electronic cash register for a cluster system that connects 2n to 2n to perform program loading and data communication. also has a main lookup file 14 consisting of non-volatile memory,
It is configured to output single item management, sales unit price, and product name to the display and printer based on the product code input from the keyboard 33 of the electronic cash register 2o and each value input device 34, and also performs a price lookup (P

0 to search for a sub-price look-up file, and if there is no sub-price look-up file, it has the function of accessing the main price look-up file of the terminal controller 1o, and automatically generates a sub-price look-up file depending on the frequency of use. It has a function.

4 and 5 show processing flowcharts of the present invention.

In FIG. 4, the electronic cash register of this embodiment performs the process of late setting of the electronic cash register's investment, investment, and input, and then performs business selection and selects each rice business. To explain the registration process as an example, we will receive and receive data from the keyboard or each stock input device, make judgments on the data such as product code, amount, number, subtotal, total, etc., and further based on this data. Processes each load.

Figure 5 is the price lookup (PLU) shown in Figure 4.
70-Chart of the process is shown. In FIG. 5, this embodiment first uses a product code to
Find the information corresponding to the product code from Price Lookup (PLU) 7 isle 38 in POS) 20,
If it is found, wait for the information to be retrieved. Next, terminal control cr -, - (TC) 10 P L U
7. If it is not found here, error processing is performed. If it is found, the usage frequency is checked. If the usage frequency is low, PLU information read processing is performed. If it is used frequently, check whether there is any unused space in the price lookup file of the electronic cash register, and if there is, the terminal controller 10,
The price lookup information corresponding to the product code is sent from PLU7 aisle 14 to the PL of the electronic cash register.
Enter U-File 38.

If there is no unused space, the electronic cash register 20
A product with a low frequency of use is searched out from the PLU file of , and exchanged with price lookup information corresponding to the product code from the terminal control 10 PLU 7 aisle 14. If there is no item that is used less frequently, the price lookup information is loaded.

FIG. 6 shows the structure of a price lookup file as a method for checking the tpae used. In the 6th iM, the price lookup file consists of a key part, a data part, a counter part, and a frequency of use check area.In particular, the check includes a counter part for checking the frequency of use, and a flag used to determine the magnitude of the frequency of use. This is done using the First, when a price lookup file is searched, the counter section is incremented by one, and the flag section is checked to determine the frequency of use.

The flag section checks the contents of the counter section at every interval (set in advance), compares it with any hani (set in advance), determines the frequency of use, and sets the result to the flag section. do.

At that time, the value in the counter section is cleared.

This fixed time and arbitrary cough are set to optimal values in the environment in which the system operates.

Thus, in one embodiment of the present invention, the electronic carrier is transferred from a large main price lookup buffer residing in the terminal controller.

Frequently used data is automatically registered in the sub-price lookup buffer of the register, and a price lookup operation is performed.

(Effects of the Invention) As explained above, the present invention speeds up price lookup processing and reduces costs, and uses non-volatile memory for the price lookup file of an electronic cash register, so that it can be saved even when the system is down. It is also effective as a countermeasure.
