Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an information processing device in which the positions of any two keys among various keys arranged on a keyboard can be exchanged.

Generally, in supermarkets, shops, etc., electronic cash registers (hereinafter referred to as ECRs) are widely used to process price information of sold products.

This ECR has keys for instructing various functional processes such as numeric keys, other department keys, and total keys on the keyboard, and the function codes of the keys corresponding to the addresses of the key code memory corresponding to the various keys. When a key on the keyboard is pressed, the function code is read from the key code memory address corresponding to the pressed key,
It executes information processing according to the function code. By the way, the keys on the keyboard are placed in the most easily operable position on the keyboard depending on the frequency of use, but because the sales situation of products changes greatly depending on the season, for example, the placement position may be changed. You may want to change it.

In such cases, conventional ECRs have a structure that once clears the contents of other memories in addition to the key code memory, and then presets all data anew.In other words, new data is preset for keys other than the key you want to change. Because of this, there was a problem that changing the key position took time and incorrect data could be preset. SUMMARY OF THE INVENTION An object of the present invention has been made to solve the above-mentioned problems, and by making it possible to exchange function codes stored at respective addresses of a key code memory corresponding to two keys. The purpose is to be able to process array changes quickly and accurately.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the present invention is applied to an ECR will be described below with reference to the drawings.

In FIG. 1, 1 is a keyboard, on the top of which there are number keys 2, department keys 3, multiplication keys 4, subtotal keys 5, total keys 6, exchange declaration keys 7 and control switches 8.
, and other necessary keys (not shown) are arranged.

Control switch 8 is set to ``Power (0FF)'' and ``Registration (
REC),” “Inspection (X),” “Payment (Z),” “Settings (SE
This is a mode changeover switch for selecting each task such as "T)". Reference numeral 9 denotes a keyboard circuit constituted by a key matrix circuit, which generates a key signal corresponding to the key position when various keys or control switches 8 on the keyboard 1 are operated, and sends a key signal to the central processing unit (CPU) 10.

Further, 11 is a display device, which is connected to the CPUIO via a display circuit 12. The CPUIO includes read-on memory (ROM) 13, random access memory (RAM
) 1 printer 16 via printer controller 15
are connected to each other.

The ROM13 stores various operations of this ECR, such as the above-mentioned "
Processing programs for various tasks set by the control switch 8, such as registration, inspection, payment, and setting, are stored. In addition, the RAM 14 includes a key code memory 21, a number register 22, a departmental memory 23, a sales amount memory 24 for one customer, X, Y, Z registers 25, 26,
27, exchange key flag memory 22, etc. are provided with respective addresses defined. Key code memo 1
As shown in FIG. 2, J21 is designed to store function code data for each key on the keyboard 1 at addresses corresponding to the keys. next,
Explain the action.

First, when setting the functions of various keys on the keyboard 1, operate the keys that you want to use as the numeric key 2 in order while the RAM 14 is all cleared.

Then, the CPUIO determines that it is a numeric key from "0" to "9" and stores the preset function code for the numeric key in the key code memory 2 corresponding to the operated key position.
Write to address 1 in order. In this way, number key 2 is first set. Next, after switching the control switch 8 to "setting", the function code of the key you want to set using the numeric key 2, for example, the function code of the total key 6 is 665σ.
If it is 1, set it as "5" or "0". Then, the CPU
In FIG. 3, the control switch 8 is in the "setting" state and the exchange declaration flag memory 28 is in the reset state. temporarily memorize it. After that, when the key at the position desired as the total key 6 is pressed, the key code memory 21 corresponding to the pressed key position
The function code data temporarily stored in the number register 22 is written to the address. Therefore, the currently pressed key is set as the total key 6. By repeating such operations, functions for other department keys 3, j multiplication keys 4, subtotal keys 5, etc. are set. When the functions of the various keys have been set through the above operations, if you wish to register the sold product, switch the control switch 8 to "Register". After that, the amount of the product is entered using the number keys 2, and then one of the department keys 3 is pressed depending on the department of the product.

Then, the CPU 10 reads the function code data stored in the address of the key code memory 21 corresponding to the pressed key, and processes the information according to the program based on the function code data. In the case of , the entered numeric data is displayed on the display 11 and is temporarily stored in the numeric register 22. In addition, in the case of the department key 3, the digit data temporarily stored in the numeric register 22 is displayed. The number data is added to the total amount data in the department memory 23 designated by the department and the data in the sales total memory 24, and then printed on the printer 16 and then cleared.By repeating this operation, all the sales After registering the product, press the total key 6 as the final closing key.Then, the function code data that supports total processing is read from the address of the key code memory 21 corresponding to the total key 6, and the program is executed based on the function code data. In other words, the cumulative data in the sales total memory 24 is displayed on the display 11 and printed on the printer 16, and then cleared.In this way, normal registration work is performed.Now, the data arranged on the keyboard 1 is cleared. To exchange the positions of any two of the various keys, switch the control switch 8 to "setting" and then press the exchange declaration key 7.

Then, the CPUIO sets the exchange declaration flag memory 28. Next, when the positions of two keys to be exchanged, for example, the subtotal key 5 and the total key 6, are to be exchanged, the subtotal key 5 and the total key 6 are pressed in sequence. Then, CPUlO
In Fig. 3, the control switch 8 is set to "Setting".
Since the exchange declaration flag memory 28 has been set, the function code data stored in the address of the key code memory 21 corresponding to the first pressed subtotal key 5 is read out and stored in the X register 25. Key code memory 21 corresponding to the total key 6 subsequently pressed
Read the function code data stored at address Y
The time is stored in the register 26. And X register 2
5 is written to the address of the key code memory 21 corresponding to the total key 6, and the function code data of the Y register 26 is written to the address of the key code memory 21 corresponding to the subtotal key 5. Therefore, the function code for the total key is stored in the address corresponding to the subtotal key 5, and the function code for the subtotal key is exchanged and stored in the address corresponding to the total key 6. The middle/subtotal key 5 in FIG. 1 functions as a total key, and the total key 6 functions as a subtotal key. In this way, the positions of the keys are exchanged with each other. Note that if you operate multiple keys (2r1) that you want to exchange in succession, the first and second keys, the third and fourth keys, the fifth and sixth keys, etc. ...
exchanged in order.

Furthermore, although the above embodiment has described the ECR, it is possible to use a keyboard as an input means, store function codes at addresses corresponding to various keys on the keyboard, and process information according to the function codes. The invention can be applied. According to the present invention, when at least two keys are operated while the exchange declaration key is operated, function code data is read from each address of the key code memory corresponding to the two keys, and the read function Since the code data is written to different addresses that are read from each other, when you want to exchange the positions of any two keys among the various keys arranged on the keyboard, press the exchange declaration key and then at least When two keys are pressed, the function codes stored in the respective addresses of the key code memory corresponding to the two keys are exchanged with each other. Since the functions of the keys are simply exchanged with each other,
In other words, unlike the conventional method in which the stored contents are once cleared and then updated with new code data, there is no problem of incorrect function codes being set, and therefore the key arrangement can be changed accurately.
