Description

How to check the changed options of the cash register

The present invention relates to a method of checking a changed option of a cash register. More specifically, when a user wants to see a changed option by storing the changed option in a buffer, the existing option and the changed option are shown together. It is about how to identify changed options of a cash register so that it is easy to see.

In general, a cash register refers to a device used to facilitate information management by processing various data accompanying a product transaction and informing a user of a result. It ranges from point of sales system to comprehensively manage distribution economy such as inventory research. Hereinafter, in the present specification, the term ECR (Electronic Cash Register), which means an electronic cash register controlled by a microprocessor, is used as a broad concept including a low-end cash register to a POS terminal.

1 is a system block diagram of a general cash register. As shown in this figure, a general cash register kisses the key input unit 20 and the key input unit 20 that generate various key codes for mode designation and money registration, and sets the mode of the ECR according to the received key code. The central processing unit 10 for designating and performing various functions in the designated mode, the ROM 30 having a system operation program embedded therein, the RAM 40 storing various data including deposit and withdrawal details, and the central processing unit 10 Display unit 50 for displaying various information related to money transactions, etc. under the control of the control panel, printer 60 for issuing documents for customer receipts and various processing results under the control of the central processing unit 10, and a predetermined key operation. It comprises a drawer drive unit 70 for drawing out the cash storage drawer when and a power supply unit 80 for supplying power to the entire system.

In the above cash registers, when using the cash register, an option for widening the selection is given. For example, an option such as a currency symbol (\, $, ￥…) may be used depending on the situation. There is a case that needs to be changed. In the conventional cash register, after the user set an option, there was a function to show which option was changed and set as a whole, but a list showing how the existing option was changed and set, that is, the existing option and the changed option was displayed. There is no function to show them together. Therefore, it is necessary to go through the user manual to find out which options have changed.

So we need a feature that shows how the existing options have changed.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned necessity, and stores changed options in a buffer so that a user can easily see which options have changed by showing the existing options and the changed options when the user wants to see the changed options. The purpose is to provide a method for identifying changed options of a cash register.

A method of confirming a changed option of a cash register of the present invention for achieving the above object, the method comprising the steps of: identifying the changed option of the cash register having a function of showing the changed option to the user, storing the changed option in a buffer; If the buffer is insufficient at the time of storing the changed option in the buffer, returning to the beginning of the buffer and storing the changed option; And outputting the changed option stored in the buffer and the existing option at the same time when there is a request to output the stored changed option.

23a. Option confirmation key

Hereinafter, with reference to the accompanying drawings will be described in detail a method of confirming the changed option of the cash register according to an embodiment of the present invention.

FIG. 2 is a key diagram illustrating an example of a key input unit in FIG. 1. As shown in this figure, the key configuration of the key input unit 20 of the cash register to which the method of the present invention is applied is a mode switch 21 used to designate an operation mode of the ECR, and a function of selecting various functions of the ECR. A key group 23, an item key group 25 used for specifying an item, and a numeric key group 27 used for specifying a price of a product. The function key group 23 may be provided with an option confirmation key 23a for viewing the changed option and the existing option.

3 is a flowchart illustrating a process of storing the changed option of the method of confirming the changed option of the cash register of the present invention. As shown in this figure, in order to change the option, the operation mode of the ECR should be switched to the program mode. In step S10, it is determined whether the operation mode of the ECR is the program mode. Depending on the model, the program can be changed in system mode. As a result of the determination in step S10, if the operation mode is the program mode, the process proceeds to step S12 to change the option to be changed, and the process proceeds to step S14 to store the changed option (hereinafter, 'output buffer') Is called). In the next step S16, it is determined whether the output buffer opened in step S14 is empty, and if it is empty, the flow proceeds to step S18 to change the changed mode, the type of option, the address, and the set value to the output buffer. Save it. In step S20, the output buffer is closed.

If the output buffer is not empty as a result of the determination in step S16, the counter of the output buffer is increased by one, and the flow proceeds to step S22 to determine whether the output buffer is the last. If the result of the determination in step S22 is the last output buffer, the process proceeds to step S26 to return to the beginning of the output buffer and overwrite the spot with the changed option. If the result of the determination in step S24 is not the last output buffer, the process proceeds to step S16 to determine whether the output buffer is empty, and if it is empty, the changed option is stored in the output buffer.

4 is an exemplary view illustrating an output buffer in which a changed option is stored after the process of storing the changed option of FIG. 3 is operated. As shown in this figure, the output buffer stores the mode in which the changed option is changed, the type of the option, the address, the setting value, and the like.

5 is a flowchart for explaining a method of confirming the changed option of the cash register of the present invention. As shown in this figure, first, in step S30, it is determined whether the operation mode of the current ECR is a program mode. As a result of the determination in step S30, when the operation mode of the ECR is the program mode, the process proceeds to step S32 to determine whether there is an input of the option check key 23a defined as a key for outputting the changed option. As a result of the determination in step S32, if the input key is not the 'check option' key 23a, the process proceeds to step S33 to perform the function of the corresponding key, and the input key is the 'check option' key 23a. In the case of, it proceeds to step S34 to determine whether the output buffer for storing the changed option is empty. If it is determined in step S34 that the output buffer is empty, there is no changed option, and the flow proceeds to step S36 to output a message that there is no changed option. This may be output to a printer, or may be output on the display unit if the display unit can also display characters. If the output buffer is not empty as a result of the determination in step S34, the process proceeds to step S38 to output the existing option and the changed option. Specifies that existing and changed options are linked to each other.

FIG. 6 is an exemplary diagram illustrating a list showing existing options and changed options that are output after the method of confirming the changed options of the cash register of FIG. 5 is operated. As shown in the figure, the mode in which the option is set, the type of the option, the address, and the setting value are printed on the existing option seat, and the mode, the type of the option, the address, and the setting value are printed.

The method of confirming the changed option of the cash register of the present invention is not limited to the above-described embodiments, and may be modified in various ways within the scope of the technical idea of the present invention.

As described above, according to the method of confirming the changed option of the cash register of the present invention, when the user wants to see the changed option by storing the changed option in a buffer, what option is changed by showing both the existing option and the changed option. The effect is easy to recognize.
