Here, it is assumed that the mode switching key 23 of the key operator section 2 is set to telephone mode. Note that when switched to telephone mode using the mode switching key 23,
The prompt "NAME?" is displayed as shown in FIG. 6(1).

In step n1, the pressed key is read in the key manual unit 2, and in step n2,
The pressed key is one of the ra number keys rP21.
1 loss is the key, but judge whether I? ! If it is a number key, proceed to step n3, otherwise proceed to step n
Proceed to step 14.

In step n3, the numeric key group 21 is set to
7 It is determined whether the bet mode (hereinafter abbreviated as A mode) is set. If it is A mode, the process proceeds to step n4; otherwise, that is, numerical input mode (hereinafter abbreviated as N mode). If it is set, the process advances to step n12.

In addition, if any key in the numeric key group 21 is pressed in A mode, f547 lag 13 (I is set to logic "1", for example, in the flag area 13), and if a key is pressed in N mode, Pt547 lag 13d is set to logic "0", for example (hereinafter, this state will be abbreviated as reset). Note that the fi47 lug 13d will be hereinafter referred to as the roll key 7 lug 13d.

In step n4, it is determined whether the roll key 7 lug 13d is set to logic "1", and if it is set, the process proceeds to step n5; otherwise, the process proceeds to step nlo, when the roll key 7 lug 13d is set. The state in which the key is pressed this time indicates that the key pressed immediately before the key pressed this time is one of the numeric keys of the numeric key group 21 in A mode, and the roll key 7 lug 13d is in the reset state. If so, it is determined that the mode was N mode immediately before the current numeric key was pressed.

Here, it is assumed that, for example, the numeric key 21h of the numeric key group is pressed and the roll key 7 lug 13d is in the reset state immediately before this pressing. In this case, proceed to step nlo.

In step nlo, the alphabet number written above the number "1" of the number key 21b that was pressed this time is

'' is displayed on the display unit 4 as shown in FIG. 6(2).

In step n8, the roll key 7 lug 13d is set because the number key 21b is pressed in the A mode.

Next, if the numeric key 21c of the numeric key group 21 is pressed in this state, from step n1 to step n2. n3
Proceeds to step 7 step n4, and in step n4, the previous A
Since the number key 21b is pressed in mode and the roll key 7 lug 13d is set, the process advances to step n5.

In step n5, it is determined whether the number key pressed last time and the r11 number key pressed this time are the same, and if they are the same, proceed to step n6, otherwise proceed to step n9. , in this case, proceed to step n9.

In step n9, the cursor moves to the right side in FIG. 3 by one digit, and in step nlo, the first alphabet ""
Input the code corresponding to "G" into the display buffer 711,
This is displayed on the display section 4 in step nil (Pt
In step n8, the same operation as the previous one is performed and the process returns to step n1.

If you press the number key 21c again at Uni,
From step n1, the process proceeds to step n5 via steps 12 to n4. In this case, since it is determined that the keys are the same, the process proceeds to step n6.

In step n6, regarding the three alphabets assigned to the pressed numeric key, following the previously input full 7 abets (the code corresponding to the alphabet is displayed in the previous step nlo of the display buffer 11, the code corresponding to "G" is The code to be input is written to the input address.The input alphabet changes by suppressing the same key is performed sequentially and cyclically in the alphabet as described above.Therefore,
In this case, i? Input the second 777 bet 'H' of the losing key 21c into the display m buffer 11, and step n
7 and display on display n4 (see figure (4) ff1)
.

Next, in this state, press the alphabet mode key 25.
If you press , it switches from A mode to N mode, and the display section 4 shows the full 77 mode as shown in tjSG diagram (5).
Extinguish the bet mode display 40a and move the cursor to 1 at the same time.
Advance one step.

Here, suppose, for example, that the number key 21a is pressed. Then, the process proceeds from step n1 to step n3, and in step n3, it is determined that the mode is N, so the process proceeds to step n12.

In step n12, the pressed number key 2
Input the code corresponding to the number "7" in 1a into the display buffer 7, display "7" at the cursor position on the display section 4, and in step n13, after displaying the number, move the cursor one more digit. move it.

In addition, as shown in FIG. 7(1), immediately after displaying "R" in the fourth digit of trS in the dot display header 41, for example, "P" is displayed.
If you want to display `` in the fifth digit, since ``R'' and ``P'' are assigned to the same number key 21e, press the cursor right movement key 27 to move the cursor forward by one. There must be. Therefore, Carmol right movement key 27
The processing when is pressed will be explained with reference to the Pt5S diagram and the 70-chart in FIG.

After reading the pressed key in step n1 shown in FIG. .

In step n14, it is determined whether the pressed key is the carmol right movement key 27. If the pressed key is the carmol right movement key 27, the process proceeds to step n1G shown in FIG. 8, and if not, the process proceeds to step n15. move on.

In step n16, roll key 7 lug 13
d is reset, and the cursor is advanced by one in step n17 (see FIG. 7(2)).

Next, press the r11 number key 21e. In this case, the process proceeds from step n1 to step n3 via step n2. In step n3, since "R" was input two times before, it is determined that the A mode is continuing, and the process advances to step n4.

In step n4, since the roll key 7 lug 13d was reset in step n16, it is determined that the reset has been performed, and the process proceeds to step n10, where the hood corresponding to the first alphabet "P" of the numeric key 21e is displayed on the display buffer 11. and display this in step nil. In this way, as shown in Figure 7 (3) “
5HARP” is displayed.

Next, the process when the period key 35 is pressed will be explained with reference to the chart 70 in FIGS. 5 and 9. For example, assume that the number key 21f is pressed immediately after "A" is displayed on the third surgical opening as shown in FIG. 11(1).

After reading the pressed key in step n1, the process proceeds to step n15 via steps n2-3 and n14.

In step n15, the pressed keys are the space key 33, the hyphen key 36, and the period key 3.
5, and if it is either, the process proceeds to step n18 in FIG. 9; if not, the process returns to step n1.

In step n18, roll key 7 lug 13
It is determined whether or not d is set. If it is set, the process proceeds to step n19; otherwise, the process proceeds to step n20. In this case, period key 35
Since "A" is displayed just before pressing, it is determined that the roll key 7 lug 13d is set, and step n19
Proceed to.

In step n19, the cursor is advanced one step, and in step n20, the code corresponding to the characters ", ' assigned to the pressed period key 35 is input into the display buffer 11, and in step n21 it is displayed.

In step n22, the cursor is advanced one step further (see FIG. 11 (2)), and the subsequent processing returns to step n1.

Note that the operation of advancing the cursor to the next digit will now be explained with reference to figure f510.

In step I11, the roll key 7 lag 1 corresponding to the 1tWL key pressed in A mode this time is
It is determined whether or not 3d is set, and if it is set, the process proceeds to step m2, and if it is reset, the process proceeds to step 3. In step 112, the cursor is not advanced, and in step 113, the cursor is advanced by one.

That is, if the same number key pressed last time in the A mode is pressed this time, the cursor does not move; otherwise, the cursor is advanced by one.

f:tS12 is a flowchart showing the process of mode switching by pressing the alphabet mode key 25. Below, with reference to the same figure, alphabet mode 2
The processing by the suppression operation No. 5 will be explained.

In step No. 1, it is determined whether the cursor position is in the dot display area 41 or in the first and second date character display areas 44, 43, and if the position of the cursor is in the dot display area 44, 41, step J! Proceed to 2, 11 up, 2nd
If it is in the Japanese character display area 44.43, step! Proceed to step 8.

Step! 2, alphabet mode key 25
It is determined whether or not the mode was A mode immediately before the button was pressed, and if it is the A mode, the process proceeds to step 13 and the mode is switched to the N mode. On the other hand, if it is in N mode, proceed to Step Noah and move to A.
mode can be switched.

In step 14, it is determined whether or not the roll key 7 lug 13d is set. If it is set, the process proceeds to step no. 5, where the roll key 7 lug 13 (I is reset, and the cursor is In this way, the cursor is also advanced by one when switching from A mode to N mode.

In step n8, since the date character display is placed, the N mode is set.

As described above, in the input method according to this embodiment, when inputting a desired alphabet character, the numeric key group 21
The desired alphabet can be selected and displayed within three presses of a predetermined number key, and
In A mode, if you press the rL numeric key that is different from the previous one, the cursor will automatically move to the right of the digit that was entered last time and is displayed, and the rL number key that was pressed this time will be placed in that digit. The character pressed by 1 on the IWL key is input and displayed. Furthermore, even when the mode is switched from A mode to N mode, the cursor advances automatically. Since the operation of advancing the cursor is executed automatically in this way, the number of operations required when inputting characters is reduced.

Effects According to the present invention as described above, in a state where a specific character can be input, after pressing any numeric key and inputting the specific character assigned to it,
If you want to input and display a numerical value, all you have to do is press the switch key to switch to a state in which numerical input is possible, and then press any new digit -. That is, in such a case, the suppression operation of advancing the four display areas to be newly displayed one character to the right is omitted, and the operability in the pressing operation is improved.
