Description

[Detailed Description of the Invention] This invention is an electronic cash register (hereinafter referred to as ECR).
In particular, the present invention relates to an ECR in which, for example, when a clear key is operated to correct an erroneously manually entered single item price, the most recently registered single item price can be called up and displayed.

Recently, two major ECRs have been put into practical use at supermarkets and the like to speed up the registration process when the store becomes crowded.

These two major EC'Rs are operators (hereinafter referred to as checkers) who manually collect the individual product registration information of the products purchased by customers.
BCR (hereinafter referred to as checker side E) as a registration unit operated by
CR) and the ECR (hereinafter referred to as the cashier-side ECR), which is a clearing unit operated by an operator (hereinafter referred to as the cashier) who receives and settles the money paid by the customer.

In such two major ECRs, the checker is the key when manually inputting the registration information for a single item.
Sometimes, when the cashier talks to you, you manually key in the wrong item registration information.

In such a case, the checker operates the clear key to correct the single item registration information that was entered incorrectly, but when the clear key is operated, only 0 is displayed on the display, so the checker operates the clear key to correct the single item registration information that was registered immediately before the clear key was operated. I don't know what the registration information was.

Therefore, conventionally, the total price of all the single item registration information registered so far was displayed on the display by operating the subtotal key, the total unit price of the products registered so far was calculated by mental calculation, and the display I compared the displayed total amount with the total amount calculated by mental calculation to find out which products I had registered so far.

Therefore, when the checker makes an operation error, it takes time to check which products have been registered, which is a heavy burden.

Therefore, the main object of the present invention is to provide an ECR that can display the single item registration information of a product with a simple operation in order to confirm the single item registration information of the product that has just been registered.

To summarize, the present invention is such that, in response to the operation of the call key manual means, the single item registration information stored in the storage means and registered immediately before is called up and displayed on the display means.

The present invention will be described in more detail below along with embodiments shown in the drawings.

Furthermore, a storage area 22c as an address register for specifying the address of the data buffers 221 to 22n each time the single item registration information of each product is entered manually;
A storage area 22d is provided as a display register for temporarily storing single item registration information to be displayed on the display 24.

FIG. 5 is an implementation diagram for explaining the procedure of key operation according to an embodiment of the present invention, and FIG. 6 is a flow diagram for explaining the operation of an embodiment of the present invention.

Next, the specific operation of one embodiment of the present invention will be explained with reference to FIGS. 1 to 6.

First, the mode setting switch 201 is set to mode R (registered operation mode).

In the initial state, the address register 22C specifies the address of the first item area 221.

First, as an example, it is assumed that the individual item registration information of a product purchased by a customer is manually entered using the procedure shown in FIG.

That is, the checker selects "100" using the numeric keypad 103.
After inputting the single item price information of ``Yen'' manually, enter the department key 10.
6. Operate the key for department code "05" included in section 6.

In response, the CPU 21 determines whether or not there is any key input from the checker side keyboard 10.

If there is no key power, the system waits, and when it is determined that there is key power, it is determined whether the key is the last call key 102 or not.

If it is not the last call key 102, it is determined whether the display on the display 11 is blank (no information is displayed).

If it is the last call key 102, it is determined whether it is a registration related key.

That is, it is determined whether the numeric keypad 103 and the department key 106 have been operated and the single item registration information has been entered manually.

If it is not a registration-related key, it is determined whether it is the clear key 105, but if it is determined that it is a registration-related key, registration processing is performed.

That is, the single item amount information "100 yen" input from the numeric keypad 103 and the department code "05" manually input from the department key 106 are stored in the display register 22d.

As a result, the department code "05" is added as the single item registration information.
and single item price information "100 yen" are displayed on the display 11 of the checker side ECR 1.

Further, the single item registration information, "o5" department and "100 yen" stored in the display register 22d are transferred to the first item storage area 221 and stored therein.

Next, the CPU 21 determines whether single item registration information is stored in the area 221.

If it is not stored, the process returns to the initial standby state, and if it is determined that it has been registered, the address register 22c is incremented to specify the address of the area 222.

Similarly to the above explanation, the single item registration information of the second product, that is, the single item price information 1200 yen'' and the department code ``16''.
'' using the numeric keypad 103 and department key 106 and stores it in the display register 22d.

Further, CP[J21 transfers the single item registration information in the display register 22d to the area 222 and stores it therein.

Next, the checker manually enters the single item registration information for the third product, but at this time, it appears that the single item price information "310 yen" was inputted using the numeric keypad 103, but the single item price information "3o" was entered by mistake. Suppose.

The checker immediately knows that the input single item price information is incorrect and operates the clear key 105.

In response, the CPU 21 determines that it is the checker side key, determines that it is not the last call key 102, determines that it is not a registration related key, and determines whether it is the clear key 105 or the tongue.

If it is not the clear key 105, other processing is performed, but if it is determined that it is the clear key 105, the display register 22
d stores the information of all F (1111).

As a result, the display on the display 11 becomes blank.

Further, the checker operates the last call key 102 to find out the single item registration information 6 (what was entered just before operating the clear key 105).

In response, the CPU 21 determines that the last call key 102 has been operated, and determines whether the display 11 is blank.

That is, it is determined whether or not all F information has been stored in the display register 22d.

If the display 11 is displaying "side", it returns to the initial standby state, and if the display 11 is blank, the content of the address register 22c is subtracted by "-1" and the clear key 105 is pressed. The address of the area 222 storing the single item registration information registered immediately before the operation is made to be specified.

Further, the CP[J21 transfers the single item price information "200 yen" and the department code "16" stored in the area 222 to the display register 22d.

As a result, the display unit 11 displays the single item amount information "20
0 yen" and the department code "16" are displayed.

Therefore, the checker looks at the second single item registration information displayed on the display 11 and easily and easily confirms that the registration of the single item registration information for the second item inputted immediately before operating the clear key 105 has been completed. It has the advantage of being able to know

When the checker learns that the single item registration information for the second item has been entered, it presses the numeric keypad 103 and department key 10 again.
6 and enter the correct single item price information for the third item "3.
10 yen" and the department code "15".

The checker operates the subtotal key 107 after inputting the single item registration information of all the products.

Accordingly, the CPU 21 stores data buffers 221 and 22.
The single item registration information stored in n is calculated and stored in the various total storage areas 22b, and the various number of times storage areas 22a are updated.

On the other hand, when the registration on the checker side is completed, the cashier operates the subtotal key 207.

In response, the CPU 21 causes the address register 22C to sequentially specify the respective addresses of the data buffers 221 to 22n, reads out the single item registration information of the first item to the nth item, causes the printer 25 to print and record the information on the receipt, and further The total amount of 22b is displayed on the display 24 and printed and recorded by the printer 25.

In the above embodiment, when the last call key 102 is operated after the clear key 105 is operated, the single item registration information manually entered immediately before the clear key 105 is operated is called up and displayed. When only the last call key 102 is operated without operating the last minute call key 105, the immediately previous single item registration information may be called.

This has the advantage that the effort of operating the clear key 105 can be saved.

Further, in the above-described embodiment, the present invention is applied to the 2-largely divided ECR, but the present invention is not limited to the 2-largely divided ECH, and may be applied to the ECR for each person.

In this case, the input single item registration information is stored in the display register, and when the department code is input, the individually provided last call register is transferred, and when the last call key is operated, the last minute call register information stored in the last call register is transferred. The single item registration information registered in is transferred to the display register and displayed on the display.

As described above, according to the present invention, the previously registered single item registration information can be easily and easily called up and displayed on the display by operating the call key manual means. This has the effect of improving the efficiency of checking work, since it is possible to immediately check whether the corrective action has been made, and to smoothly move on to the registration operation after the correction operation.
