The present invention relates to a method for checking information on a function key in an electronic cash register, and more particularly, to a method for checking a program state or a sales status of a function key in a registration mode.

Generally, the cash register used for the merchandise sales management, as shown in FIG. 1, has a central processing unit (hereinafter referred to as a CPU) 10 for controlling the operation of each part of the system, various commands and A keyboard 20 for inputting data, a memory 30 for storing various control programs and data, a printer 40 for printing receipts for large customers and an audit paper for store storage, data processing and various system states, etc. It is composed of a display unit 50 for displaying and the keyboard 20 is a mode switch (SW), a numeric key and a function key to switch the system state to the registration, report, program mode as shown in FIG. It consists of a confirmation key (K), a subtotal key and a cash / deposit key. However, the conventional cash register was to perform each function according to the mode according to the state of the mode selection switch (SW), so that the programmed for various functions such as items or price look up (hereinafter referred to as PLU). To check the contents, we had to check in the program mode, and to see the sales details, we had to check in the report mode.

So, for example, if you forget the program contents of an item or PLU during the program and want to find out what is programmed, you have to go to the program mode and check, but if you are registering at this point, you cannot switch to another mode. After completing the exchange registration, it was inconvenient to use because it had to switch to the program mode and check.

In addition, in order to view the sales activity history of an item or PLU, the system status should be checked by switching the system status to the report mode for issuing a report, but the use of a key for issuing a report is permitted only to a salesperson who is at least in charge. In general, a general salesman who handles registration tasks does not have a key to switch to report mode. Therefore, there is no way to check the desired function when the key does not have.

It is therefore an object of the present invention to provide a method for verifying information on an arbitrary function key in a registration mode or during a registration operation.

Hereinafter, the present invention will be described with reference to the accompanying drawings.

1 is a system block diagram of a cash register to which the present invention is applied, the configuration of which is as described above.

2 is a diagram illustrating the configuration of a keyboard in FIG. 1, and specific key configurations are the same as described above.

3 is a diagram illustrating a memory map according to the present invention. FIG. 3a is a program area for storing programmed contents for each function key, FIG. 3b is a report area for storing sales activity details, and FIG. 3c is a check of each state. As flags for F1, F1 is a flag indicating whether or not it is ready for confirmation, F2 is a flag indicating whether or not it is in the registration operation, F3 is a flag indicating whether or not the registration is completed, F4 is a confirmation Flag indicating whether or not the report content is included.

4 is a flowchart of the present invention.

FIG. 5 shows the key assignment state according to the confirmation number, FIG. 6 shows the display state (FIG. 6A) and printing state (FIG. 6B) when checking program heat resistance, and FIG. 7 shows the report sales history. The display state (Fig. 7a) and the printing state (Fig. 7b) of the city are shown.

The present invention will be described in detail based on the above configuration. For example, in order to check the programmed details for the item 1 key, the user first enters a key to select the program details check, enters a confirmation key, then enters the confirmation number corresponding to item 1, and then confirms the key again. Enter.

That is, when using the numeric key as a key for selecting which details to check, assuming that the program history confirmation key is the numeric key ＂1＂, the confirmation number corresponding to item 1 is set to 1 as shown in FIG. Therefore, in order to confirm the program details for the item 1 key, the key input operation is executed in the order of 1 (program details confirmation key) → confirm key → 1 (confirmation number key for item 1)-confirm key ＂.

Referring to the operation processing according to the key processing, in step (1) of FIG. 4, the CPU 10 checks whether a confirmation key is input and performs a general registration operation when the confirmation key is not input. On the other hand, when the confirmation key is input, the process proceeds to step (2) to check whether the first flag F1 is set.

Here, the first flag F1 indicates whether or not the preparation for checking the details is completed. Therefore, when it is found that the first flag F1 is not set, the process goes to step (3) to check whether the input number is larger than two.

In the step (3), if the input number turns out to be more than that, the error is processed.

If it is determined in step (3) that the input number is not greater than 2, the process proceeds to step (4) and checks whether the input number is 1. In this case, if the input number is found to be 1, in step (5), the fourth flag (F4) indicating whether or not to check the program details is set. If not, it means that the input number is 2. 5 flags F5 are set.

After completing step (5) or step (6), the process proceeds to step (7) to check whether the current state of the cash register is in the process of registering.

If the check result is found to be registered, the process proceeds to step (9) to set the second flag (F2) to prepare the program content or report content through the display device. On the other hand, when the registration operation is not completed, the registration operation is completed, and in step (8), the third flag F3 is set to prepare to print the program contents or the report contents.

After the completion of the steps (8) and (9), the process proceeds to the step (10), where the first flag F1 is set to indicate that the preparation of the confirmation of the details is completed and returned.

On the other hand, when it is found in step (2) that the first flag F1 is set, the process proceeds to step (11) to check whether the input number is valid as the confirmation number. If the result of the check is not valid as the confirmation number, error processing is allowed.

On the other hand, when the input number is valid as the confirmation number, the process proceeds to step 12 to check whether the fourth flag F4 is set, and recognizes that the program content is checked when the set state is set. The corresponding program contents are patched into the program area as shown in the memory map of FIG. 3 (FIG. 3A).

However, if it is determined in step (12) that the fourth flag F4 is not set, the process proceeds to step (17) to check whether the fifth flag F5 is in the set state.

If the fifth flag F5 is not in the set state as a result of the inspection, error processing is performed, and at the time of the set state, it is recognized that the contents of the report are confirmed. In step 18, the contents are stored in the memory map of FIG. Patch from the report area as shown.

After the completion of step (13) or step (18), in step (14), it is checked whether the second flag F2 is in the set state, and the set state is shown in FIGS. 6a and 7a. Display as shown.

If it is determined in step (14) that the second flag F2 is not set, the process proceeds to step (19) to check whether the third flag F3 is set. At this time, if the third flag F3 is not set, error processing is performed. When the set is made, the patch is printed on the resin as shown in FIG. 6B or 7B in step (20). After performing step (15) or step (20), the process proceeds to step (16) to initialize and return the first to fifth flags F1 to F5.

As described above, the program details or sales status of each function key can be checked with the display device during registration, and upon completion of registration, the printing can be checked on the receipt and the sales can be checked at any time. There is also an advantage to the accuracy of the registration operation.
