DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to an input display method in, for example, an electronic cash register or a computer.

BACKGROUND ART In conventional electronic cash registers, after registering money, a correction key or a repeat key is operated to perform so-called functions corresponding to those keys. The range of motion performed by the button is predetermined. Therefore, in order to correct a range other than the predetermined range or to repeatedly input data, a new key input operation is required.
Therefore, key input operations are time-consuming.

Purpose It is an object of the present invention to provide an input display method that allows key operations to be performed easily and without error.

Structure and Effects of the Invention The present invention provides (a) data input means having a cursor movement key and other keys; and (b) data input means that receives an output from the data input means and performs sequential key input operations. (c) a memory for storing the calculation results of the processing means; and (d) means for displaying the calculation results of the processing means. The processing means has a guide display area for displaying the procedure, and a cursor that can move in the guide display area, and the processing means displays the key input operation procedure in the guide display area, and moves the cursor by operating the cursor movement key. This is an input display method characterized by moving the cursor and performing arithmetic processing on subsequent key inputs instead of arithmetic processing after the cursor's stop position.

According to the present invention, the display means has an area for displaying the key input operation procedure, and after moving the cursor in this guide display area and visually confirming the stopping position of the cursor, the display means performs the subsequent key input operation. Since the process can be performed continuously, key operations can be performed easily, and the operation can be confirmed on the display means, so that key input operations can be performed without errors.

Embodiment FIG. 1 is a front view of a keyboard 1 provided in an electronic cash register according to an embodiment of the present invention.

% discount. At this time, the display is as shown in FIG. 31. The cursor is at the position indicated by reference numeral 24.

To make a correction, operate the cursor movement key 14 to move the cursor to the left in FIG. As shown in FIG. 3, when the cursor is stopped at the position indicated by reference numeral 25 and the correction key 11 is operated there, the entered value 10 and the operation of the discount key 13 are corrected. Furthermore, when the correction key 11 is operated with the cursor located at the position indicated by the reference mark 26, the department key 8 and the numeric keypad 7 are pressed.
and the operation of the discount key 13 are all subject to correction processing.

4 and 5 are diagrams showing the storage state of the buffer 20 prepared in the random access memory 4, the display state by the display means 5, etc. This buffer 20 is equipped with two counters PTC and TC. The counter PTC stores the current cursor position and
The TC stores the counter position that is the motorization condition. Note that the cursor position in the guide display area 22 of the display means 5 and the values of the counters DTC and TC in the buffer 20 do not necessarily match;
The content of is corrected and the position of the cursor is displayed by the display means 5 based on the result of this correction calculation. By operating the first department key 8 as shown in FIG. 4, the code A1 corresponding to the first department key 8 is stored in position 1 of the buffer 20. Therefore, as shown in FIG. 4, line 10 is entered by operating the numeric keypad 7 for a 10% discount. Thereafter, the discount key 13 is operated. As a result, the code A2 corresponding to the discount key 13 is stored in position 5.

To make the correction, move the cursor movement key 14 to the left from the position of reference numeral 27, as shown in FIG. By operating cursor movement key 14 twice, the cursor reaches the position indicated by reference numeral 28. When the correction key 11 is then operated, the code A3 is stored in position 6, and the value 10 and the operation of the discount key 13 are corrected. The value of the counter TC is moved to position 2 by operating the cursor movement key 14, and the value 2 is stored.

Also, as shown in Figure 5 1, to register money for 987 items at a unit price of 1234 yen, use the numeric keypad 7.
Enter 987 by operating , then operate the unit price key 31, and then input the amount of 1234 yen by pressing the numeric keypad 7.
Enter by. This places the cursor at the position indicated by reference numeral 29. In the prior art,
If the correction key 11 is operated here, the value 987, unit price key 31 and value 1234 will be corrected.
According to the invention, for example, only the value 1234 can be cleared.

If the cursor is located at the position indicated by the reference mark 29 as shown in FIG.
If 1 is operated further, it is determined that a key input error has been made, and the cursor is automatically moved to the position indicated by reference mark 30. At this time, the store contents in positions 5 to 7 where the value 1234 was input are automatically cleared, and the value 987 and the code E of the unit price key 31 are cleared automatically.
1 is stored. In this way, the cursor automatically returns to the position where a valid key operation was performed.

As shown in FIG.
Alternatively, when the cursor movement key 14 is operated, the cursor moves to the position indicated by the reference mark 31, and the code E1 of the unit price key 31 stored at position 4 is cleared accordingly.

Referring to FIG. 6, the process moves from step n1 to step n2, and when it is determined that there is a key input, the process moves to step n3, where the logic becomes "1" when an error occurs. Flub FERR is logic “1”
If not, step n
4, it is determined whether the cursor movement key 14 has been operated. When the cursor movement key has been operated, the process moves to step n5, where the content of the counter TC is changed by the number of times the cursor movement key 14 has been operated to correct the display position of the cursor on the display means 5, and based on this correction result, the process proceeds to step n5. At n6, a cursor is displayed.

When the cursor movement key 14 is not operated, the process moves from step n4 to step n7, and it is checked whether the key input operation is performed according to a predetermined procedure and the condition is satisfied. If the key sequence is correct, move on to step n8 and buffer 2
Enter the key code in the store location 0. At this time, the cursor is moved and the counter is moved accordingly.
The contents of PTC and TC are changed. This counter
The contents of PTC and TC are corrected, and a cursor is displayed by the display means 5 in step n9.
In step n10, it is determined whether a motorized key, that is, a key for causing some action, has been operated, and if so, steps n11 and n1 are performed.
2,..., n13 etc., PLU key 12 or
It is determined whether it is the department key 8 or the correction key 11. The operations corresponding to the keys 12, 8, and 11 are performed in step n21, and the display means 5 displays the information, and the printer 6 performs printing.

If the key sequence is incorrect, the process moves from step n7 to step n15, and the flag FERR is
is set to logic "1". At step n16, the cursor is moved to a valid store position in the buffer 20, and the contents of the counter TC are changed. The contents of this counter TC are corrected and step n
At 17, the display means 5 displays a cursor.

If an error has occurred, the process moves from step n3 to step n18 and waits for the clear key to be operated. When the clear key 10 is operated, the process moves to step n19 and the flag FERR is set to logic "0". In step n20, the store position of the buffer 20 is cleared according to the number of operations of the clear key 10, and the cursor is moved to the counter TC.
The contents of will be changed. At step n21, the error display is canceled and the cursor moves to the counter.
It is displayed correctly in a corrected position based on the TC value.
