Abstract

PURPOSE:To provide an electronic telephone directory where the key operation for a retrieval is easy and the telephone number of the retrieval result is easy to be seen. CONSTITUTION:When characters to be basic are arrayed in a matrix shape, the characters corresponding to the one line of a matrix are displayed on a display area 83. When cursor keys 6L and 6R are operated, a cursor is moved one character by one character in a line direction in a display area 83. When cursor keys 6U and 6D are operated, the display of the character in the display area 83 is made to scroll in the column direction at least for a column where the cursor is displayed. When a definite key 6K is operated, the character at the location where the cursor is displayed is fetched in the display area 83. By defining this fetched character as a keyword, the character string of a memory is retrieved. By continuously using the display area 83 and a display area 84 in the up and down directions, the telephone number of the retrieval result is magnified and displayed.

And the second line has the lowercase letters "nz" in the alphabet.

Further, the table NUMT is a data table for inputting numbers, and has numbers and symbols which are considered to be necessary for inputting telephone numbers in a matrix. That is, the number table NUMT has a size of 4 rows × 13 columns, and the first row thereof has the numbers “0 to 9” and the symbol “−”.
() ”, And each of the second to fourth lines has various symbols and characters of 13 characters per line. In addition, this second line
The symbols and characters in the fourth line are mainly used when the electronic telephone directory is used as a memo pad or a calculator.

In the following description, kana characters,
For English letters and numbers, KANAT Kana table and ALP alphabet table
The symbols of HT and the numerical table NUMT are also included. In addition, when simply described as “letter”, it represents a kana character, an alphabetic character, a number, and their respective symbols.

FIG. 3 shows a concrete example of the operation keys 6 and an arrangement example thereof. That is, FIG. 3 is a front view of an electronic telephone directory having the above-described circuit. 6L and 6R are horizontal cursor keys, 6U and 6D are vertical cursor keys, and 6K is an enter key for confirming characters that have been input. Is. Also, 6M
Is a mode key for switching the operation mode between the search mode and the input mode. 6C is a kana character, alphabetic character,
A character type key 6H for switching between numbers is a direct search key for directly inputting and searching the name of the other party. Further, 6S is a correction key for correcting or correcting an input character, 6N is a deletion key for deleting the input character, 6I is an insertion key for inserting a character, and 6I.
T is a registration key for registering the input data.

Each of the keys 6 is composed of a non-lock type push switch. Although not shown, the keys 6M to 6T arranged below the chain line in FIG. 3 are provided in a pocket and are normally covered with a cover and are pressed by mistake, and the keys 6L to 6K are frequently used. It is designed so as not to interfere with pressing.

Further, FIG. 4 shows an example of the display section of the LCD 8 (this figure shows a state in which all the display sections are lit). In this example, the LCD 8 has display areas 81 to 85. Have. That is, the display area 81 is
Of the cursor keys 6L to 6D, the cursor keys that can be used at that time are displayed. For example, if the display element Δ or ▽ in the display area 81 is lit, the up and down cursor keys 6U or 6D
Indicates that it can be used.

Further, the display area 82 is for displaying the operation mode of the electronic telephone directory, and has three display portions showing an input mode, a search mode, a correction mode and the like.

Further, the display areas 83 and 84 are for displaying the name and telephone number of the other party. Therefore, the display area 83 has display portions 83A to 83M for 13 characters arranged in the left-right direction, and these display portions 83A to 83M are formed by display dots of 7 dots (vertical) × 5 dots (horizontal). The characters are displayed by the combination of the lighting of the dots.

The display area 84 is also constructed in the same manner as the display area 83, and is arranged in the left-right direction.
The display units 84A to 84M for three characters are provided, and these display units 84A to 84M are composed of display dots of 8 dots (vertical) × 5 dots (horizontal), and the characters are displayed by a combination of lighting of the dots. It is a thing.

In this case, the display unit 83 and the display unit 8
4 is the display dot in the bottom row of the display unit 83 and the display unit 8
The display dots in the uppermost row of 4 are arranged so as to be close to each other. Therefore, the display areas 83 and 84 as a whole have 13 display sections arranged in the left-right direction, and each of the display sections has 15 dots (vertical) ×
It is also composed of display dots of 5 dots (horizontal).

However, when characters are displayed on the display unit 84, in principle, the uppermost line of the display unit 84 is not used for display. Therefore, when a character is displayed on each of the display units 83 and 84, a one-dot blank is displayed between the character displayed on the display unit 83 and the character displayed on the display unit 84. .

<Outline of Operation> FIG. 5 shows a general operation of the electronic telephone directory. That is, when the power switch is turned on, the process of the CPU 1 starts from step 21, then in step 22, the search mode is set, and in step 23, the key input is waited.
That is, when the power is turned on, first, the search mode is entered.

When a key is input, this is checked in step 24, and the telephone number is input (registered).
When the key input is for the key input, the process goes to the input mode of the name and telephone number of the other party in step 25, and the telephone number is registered. When the registration is finished, the process returns to the search mode in step 22.

If the key input is a key input relating to the retrieval of the telephone number in step 24, the telephone number of the other party is retrieved in step 26, and the retrieval mode is continued in step 22 after the retrieval. Next, the details of the process and operation of the input mode and the search mode will be described.

<< Input of Name and Telephone Number (Registration) >> When the power is turned on, the processing of the CPU 1 starts from step 101 of the routine 100, then the initial setting of each part is executed by step 102, and then step 103
At, the search routine 400 is executed.

The details of this routine 400 will be described later, but in this routine 400, the mode key 6
When M is pressed, the search mode ends, and the process proceeds from step 103 to step 111. This step 111
After that, input mode of name and telephone number (registration mode)
The processing contents and operation are as follows.

That is, in step 111, the flag CMF is set to CMF = 0. This flag CMF is
Whether the characters to be entered are kana characters, alphabetic characters, or numbers, or when entering characters, the character table
It indicates which table of KANAT, ALPHT or NUMT is used. For example, CMF = 0 ・ ・ ・ Kana characters (use Kana table KANAT) CMF = 1 ・ ・ ・ English characters (use alphabet table ALPHT) CMF = 2 ... Numerical value (using numerical table NUMT).

Then, in step 112, the display area 83 of the LCD 8 is displayed as shown in FIG. 12A, for example.
In the display portions 83A to 83M, the characters "A-A" in the column of the kana table KANAT are displayed one by one, and the characters "Name?" Are displayed in the display area 84. Then, in step 113, The input processing routine 200 is executed.

Although details of this routine 200 will be described later, in this routine 200, input of a name or a telephone number is requested, and when the input is normally completed, the registration key 6T is pressed to input. To cancel, the mode key 6M is pressed. In addition, a registration flag REGF is prepared in the routine 200,
When the registration key 6T is pressed (normal end), REGF =
When the mode key 6M is pressed (when stopped), REGF = 0 is set, and the routine 200 is ended.

When the routine 200 is executed in step 113, CMF = 0, so the name is input. When the registration key 6T is pressed after the input of the name is normally completed, the process proceeds from step 113 to step 114, and in this step 114, the registration flag REGF is checked.

Then, in the present case, the processing is normally terminated and REGF = 1.
Therefore, the process proceeds from step 114 to step 115. In this step 115, CMF = 2 is set, and then in step 116, as shown in FIG. 18A, for example, as shown in FIG.
In 83M, the characters "0-" in the first line of the numerical table NUMT are displayed one by one, and the character "bang?" Is displayed in the display area 84.
At 7, the input processing routine 200 is executed.

In this step 117, routine 2
When 00 is executed, the telephone number is input because CMF = 2. Then, when the registration key 6T is pressed after the input of the telephone number is normally completed, the process proceeds from step 117 to step 118, and in this step 118, the registration flag REGF is checked. Then, in this case, since the processing is normally completed and REGF = 1, the process proceeds from step 118 to step 119, and in this step 119, the name and telephone number input in steps 113 and 117 are R.
Registered in AM4. At the time of this registration, sorting is performed, and the names and telephone numbers are registered in the order of names, for example, Iwayo.

Then, the process returns from step 119 to step 103 to enter the search mode again and waits for the next key input in step 104.

When the mode key 6M is pressed in the middle of inputting the name in step 113 to stop the input of the name, REGF = 0 is set and step 113 is ended, and this REGF = 0 is detected in step 114. Then, the process returns from step 114 to step 103.

Similarly, in step 117, when the mode key 6M is pressed during the input of the telephone number to stop the input of the telephone number, REGF = 0 is set and step 11
7 is ended, and this REGF = 0 is step 118.
, And the process returns from step 118 to step 103. Therefore, when the name or telephone number is input, the registration can be canceled by pressing the mode key 6M.

<< Processing Content of Input Processing Routine 200 >> The processing content when the routine 200 is executed in steps 113 and 117 is as follows.

That is, the processing of the CPU 1 is the routine 2
00, step 201, then step 2
02, the flag CMF is checked, and when CMF = 0 (for example, the routine 20 in step 113).
(When 0 is executed), the process proceeds from step 202 to step 203. Then, in this step 203, as shown in FIG. 12A, for example, the kana table KA is displayed on the display portions 83A to 83M of the display area 83 of the LCD 8.
The characters "A-A" in the NAT column are displayed one by one, and the cursor CSR is displayed on the display portion 83A of "A" at the beginning. Then, in this state, the process proceeds to step 206 and waits for key input.

Although the cursor CSR is indicated by □ in the figure, the cursor CSR is actually represented by reversely displaying the character at the cursor position.

Therefore, when CMF = 0, the kana input mode is set. Also, from this, step 113
When the routine 200 is executed in FIG.
As shown in FIG. 2A, a request for inputting a name is displayed, and key input is awaited in the kana input mode.

In step 202, CMF = 1
If so, the process proceeds from step 202 to step 204.
Proceed to. Then, in this step 204, for example, as shown in FIG. 16A, the characters “A to M” on the first line of the first group ALPH1 of the alphabet table ALPHT are displayed on the display portions 83A to 83M of the display area 83 of the LCD 8 as one character. Are displayed one by one, and the display section 83A of "A" at the beginning is displayed.
The cursor CSR is displayed at. Then, in this state, the process proceeds to step 206 and waits for key input. Therefore, when CMF = 1, it becomes the alphabet input mode.

Further, in step 202, CMF =
2 (for example, when the routine 200 is executed in step 117), the process proceeds to step 20.
From 2 to step 205. And this step 2
05, the LCD 8 as shown in FIG. 18A, for example.
In the display areas 83A to 83M of the display area 83, the numbers "0" in the first line of the number table NUMT are displayed one by one, and the display section 83A of "0" at the beginning thereof is displayed.
The cursor CSR is displayed at. Then, in this state, the process proceeds to step 206 and waits for key input.

Therefore, when CMF = 2, the numeral input mode is set. Also, from this, step 117
When the routine 200 is executed in FIG.
As shown in FIG. 8A, a request for inputting a number is displayed, and the key input waiting mode is entered.

Switching of Character Type to be Input To switch the type of character to be input among kana characters, alphabetic characters and numbers, the character type key 6C is pressed while waiting for key input in step 206.

Then, the process proceeds from step 206 to step 207. In this step 207, it is determined that the key input in step 206 is the character type key 6C, and the process proceeds from step 207 to step 211.
Proceed to. Then, in step 211, the flag
The CMF is incremented by "1" and then the process returns to step 202. In step 211, when CMF = 3 as a result of the flag CMF being incremented, CMF = 0 is changed.

Therefore, each time the character type key 6C is pressed, the flag CMF is repeatedly changed in the order of 0 → 1 → 2 → 0 → ... and the character table corresponding to the value of the flag CMF is displayed in the display area 83. Is displayed and the key input is awaited. That is, each time the character type key 6C is pressed,
The input mode repeatedly changes in the kana input mode → alphabet input mode → numeric input mode → kana input mode → ....

-1 When Inputting Characters in Kana Table KANAT Here, an example is given in which the name "Ooki" is input in step 113. Then, the name "Ooki" is all kana characters and Step 1
When the execution of the routine 200 is started in step 13, the kana characters of the kana table KANAT are displayed in the display area 83 by steps 111, 202 and 203.
It is in Kana input mode.

Since the first letter "O" of this name "Ooki" is in the A line, the up and down cursor keys 6
Press U or 6D. Then, the process is step 206.
From step 207 to step 207, the key input in step 206 is discriminated in this step 207, and in this case, the up / down cursor key 6U or 6D is pressed, so the process proceeds from step 207 to step 221.

Then, in this step 221, the flag CMF is checked, and in this case, CMF = 0, so the processing advances from step 221 to step 222, and in this step 222, the cursor CSR is displayed in the display area 83. Only the specified line is scrolled vertically by one character (in the line direction by one column).

In this case, if the downward cursor key 6D is pressed, as shown in FIG.
If the character displayed in A is changed from "A" to "I" and the up cursor key 6U is pressed,
As shown in FIG. 12E, the character displayed on the display unit 83A is changed from "A" to "O". Further, the character currently displayed at the position of the cursor CSR is blinked and displayed on the first character display portion 84A of the display area 84. It should be noted that the display of the letter "Ka" in the column displayed on the display units 83B to 83M is not changed. Then, the process returns from step 222 to step 206.

Therefore, when the downward cursor key 6D is pressed, as shown in FIGS.
The character displayed at the cursor position (the character displayed on the display unit 83A) is "A" → "B" → "C" →
It repeatedly changes in a positive order, such as "E" → "O" → "A" → .... If you press the up cursor key 6U, the character displayed at the cursor position
"A" → "O" → "E" → "U" → "A" → "A" → ...
It repeatedly changes in the reverse order. Furthermore, the display of the display unit 84A also changes in response to this change in display, and the same character as the character displayed at the cursor position blinks on the display unit 84A.

By pressing the key 6U or 6D in this way, as shown in FIG. 12E, when the cursor position and the display section 84A indicate "O" which is the target in the present case, the key is pressed in step 206. Press the Confirm key 6K while waiting for input.

Then, in step 207, it is determined in step 206 that the confirm key 6K has been pressed, and the process proceeds from step 207 to step 241. In step 241, the character "o" displayed on the display section 84A is displayed. Is changed from a blinking display to a continuous lighting display, and then, in step 242, the character code of the character “o” currently displayed at the cursor position and the display portion 84A is written in the buffer area of the RAM 3, and then,
The process returns to step 206 and waits for key input. Therefore, the first character "O" of the name "Ooki" can be input.

Next, regarding the input of the second character "O", the display of the display area 83 is not changed at the time when the enter key 6K is pressed with respect to the first character "O". That is, as shown in FIG. 13, "o" is displayed on the display unit 83A, and the cursor CSR is still displayed on this "o".
Press the OK key 6K.

Then, the processing proceeds from step 206 to step 241 through step 241 and, as described above (FIG. 13), "O" displayed on the display portion 83A is the second character display portion 84B of the display area 84. Is continuously lit and displayed, then in step 242, the character code of the character “o” currently displayed on the cursor position and the display portion 84B is written in the buffer area of the RAM 3, and then the process returns to step 206. , Wait for key input. Therefore, as shown in FIG. 13, the name "Ooki"
This means that the second character "o" can be entered.

Further, regarding the input of the third character "Ki", since this "Ki" is in the K line of the kana table KANAT, the left and right cursor keys 6L or 6R are pressed.
Then, the process proceeds from step 206 to step 207. In this step 207, the key input in step 206 is discriminated, and in this case, the left and right cursor keys 6L or 6R are pressed, so the process proceeds to step 207. To step 231.

Then, in this step 231, the flag CMF is checked, and in this case, CMF = 0, so the processing advances from step 231 to step 232, and in step 232, as shown in FIG. Kana table KANA on the display sections 83A to 83M of
The character in the column of T is displayed, and then in step 233, the cursor CSR moves in the display area 84 by one character in the left-right direction (for one line in the step direction).

In this case, if the cursor key 6R to the right is pressed, the display section 83 is displayed as shown in FIG. 14A.
If the cursor CSR displayed on A is moved from “A” on the display unit 83A to “F” on the display unit 83B and the leftward cursor key 6L is pressed, as shown in FIG. The cursor CSR displayed on the portion 83A moves from "a" on the display portion 83A to "a" on the display portion 83M. Further, the character displayed at the current position of the cursor CSR is the third character display portion 84C of the display area 84.
Flashes on the display. Then, the process is step 2
The process returns from 33 to step 206.

Therefore, each time the right cursor key 6R is pressed, each time the cursor key 6R is pressed, as shown in FIGS.
The cursor CSR repeatedly moves the display area 83 from line A to line 13. Also, the left cursor key 6L
When is pressed, the cursor CSR repeatedly moves the display area 83 from the 13th line to the A line each time the button is pressed. Further, the display of the third character display portion 84C also changes in response to the change in the cursor position, and the right cursor key 6R
Each time you press, each time you press it, the letters "a" in column A are repeatedly displayed in a normal order, and each time you press the left cursor key 6L, The characters "a-a" in the row A are repeatedly displayed in reverse order.

By pressing the key 6L or 6R in this way, as shown in FIG. 15A, the cursor CSR is moved to the "K" of the line to which the "K" belongs, and "K" is displayed on the display section 84C. Is displayed.

When such a display state is reached,
Then, press the up / down cursor key 6U or 6D.
Then, like when selecting the first character "O" of the name "Ooki", step 222 is executed each time the key 6U or 6D is pressed, and when the downward cursor key 6D is pressed, each time the key is pressed As shown in FIGS.
The characters displayed on the display unit 83A are "ka" → "ki".
→ “K” → “K” → “K” → “K” →… It repeatedly changes in the normal order. When the up cursor key 6U is pressed, each time the character is displayed, the character displayed on the display unit 83A is "K" → "K" → "K" → "K" → "K" →
It repeatedly changes in the reverse order, such as "F" → .... further,
The display of the display unit 84C also changes in response to this change in display, and the same character as the character displayed at the cursor position blinks on the display unit 84C.

In this way, by pressing the key 6U or 6D, when the desired "ki" is displayed on the cursor position and the display portion 84C, the next step 2
When the key input is awaited at 06, the enter key 6K is pressed.

Then, in step 207, it is detected that the enter key 6K is pressed in step 206, and the process proceeds from step 207 to step 241. In step 241, the character "key" displayed on the display section 84C is displayed. Is changed from a blinking display to a continuous lighting display, and then in step 242, the character code of the character “ki” currently displayed on the display unit 84C is written in the buffer area of the RAM 3, and then the processing is performed in step. 20
Return to 6 and wait for key input. Therefore, the third character "ki" of the name "Oki" can be input.

Then, since the input of the name is completed, when the registration key 6T is pressed, this is judged at step 207, and the processing from step 207 to step 251.
Then, in step 251, the registration flag REGF is entered.
Is set to REGF = 1, and then, in step 252, this routine 200 ends.

When the mode key 6M is pressed during the input of the name, this is judged in step 207 and the process proceeds from step 207 to step 261. In this step 261, REGF = 0 is set, and then step At 252, the routine 200 ends.

Therefore, when the routine 200 is executed in step 113, when the routine 200 is terminated and the process proceeds to the next step 114, the process branches according to the registration flag and the name input is normally terminated. If (REGF = 1), step 115 and subsequent steps are continued, and if input of the name is stopped (REGF = 0), step 10
I will return to 3. Also, input the name normally,
When the step 115 and the subsequent steps are continued, the data of the input name is stored in the buffer area of the RAM 3 in the step 24.
2 is written.

As described above, the kana table KA is used as the name.
You will be able to enter characters that are in NAT. Further, since the kana table KANAT also has characters and symbols other than the Japanese syllabary, these characters can also be used for the name, and a name such as "Tokkyofu" can be input.

-2 When entering characters in the alphabet table ALPHT The key operation is basically the same as when entering characters in the kana table KANAT.
A group and a column of the alphabet table ALPHT are selected by L and 6R, and a row is selected by the up and down cursor keys 6U and 6D to specify a desired alphabet.

Here, in step 113, "O
An example is given in which the name "hki" is entered. Then, the name "Ohki" is all alphabetic characters, and when the execution of the routine 200 is started in step 113, the kana characters of the kana table KANAT are displayed in the display area 83 by the steps 111, 202 and 203. , Kana input mode.

Then, first, as described above, the character type key 6C is pressed to enter the alphabet input mode (CMF = 1). Then, as shown in FIG. 16A, in the display area 83, the character "A" in the first line of the first group ALPH1 of the alphabet table ALPHT is displayed.
~ M "is displayed.

Since the first character "O" of the name "Ohki" is in the first row of the second group ALPH2 of the alphabet table ALPHT, the left and right cursor keys 6L or 6R are pressed. Then, the process proceeds from step 206 to step 231 to step 231.

Then, in this step 231, the flag CMF is checked, and in this case, CMF = 1, so the processing advances from step 231 to step 234, and in step 234, the display in the display area 83 is changed to the cursor key 6L or 6L. Changed to correspond to 6R.

That is, when the right cursor key 6R is pressed, the cursor CSR displayed on the display section 83A changes from "A" on the display section 83A to "B" on the display section 83B as shown in FIG. 16B. Moving. Further, the character “B” displayed at the current position of the cursor CSR is blinked and displayed on the first character display portion 84A of the display area 84. Then, the process returns from step 234 to step 206. Therefore, the right cursor key 6
Whenever R is pressed, as shown in FIGS. 16A to 16C, the cursor CSR moves the display portions 83A to 83M by one character at a time, and the alphabet at the cursor position blinks on the display portion 84A. Is displayed.

However, as shown in FIG. 16D, the cursor
When the cursor key 6R is pressed when the CSR has moved to the rightmost display portion 83M, as shown in FIG. 16E, in the display area 83, the letters "N to Z" of the second group ALPH2 of the alphabet table ALPHT are displayed. Displayed and cursor CSR
Is located on the display unit 83A displaying the "N". Further, the character "N" at the cursor position is displayed on the display unit 8
Flashes on 4A.

After that, the right cursor key 6R
Each time is pressed, the cursor CSR moves in the display area 83 in the direction from “N” to “Z” by one character at a time, and the letter at the cursor position is displayed blinking on the display portion 84A.

Then, as shown in FIG. 16F, the cursor
When the right side cursor key 6R is pressed when the CSR is moved to the display portion 83M displaying “Z”, FIG. 16A is displayed.
As shown in, the display area 83 has an alphabetic table ALPH.
The letters "A to M" of the first group ALPH1 of T are displayed, and the cursor CSR is located on the display portion 83A displaying that "A". Further, the character "A" at the cursor position is displayed blinking on the display portion 84A.

Therefore, when the right cursor key 6R is pressed, the cursor CSR can be moved in the normal order with respect to the letters "AZ".

When the leftward cursor key 6L is pressed from the display state of FIG. 16A, similarly, the display state of FIG. 16A → the display state of FIG. 16F → ... → The display state of FIG. 16E → the display state of FIG. 16D. → ... → Display state of FIG. 16C → Display state of FIG. 16B → Display state of FIG. 16A → Display state of FIG. 16F → ... The display state and the cursor position change.

Therefore, when the leftward cursor key 6L is pressed, the cursor CSR can be moved in the reverse order with respect to the letters "AZ".

In this way, the cursor CSR is moved to the desired "O", and when "O" is displayed on the display section 84A, the enter key 6K is pressed. Then, in the same manner as in the kana input mode, in steps 241, 242, the "O" of the display section 84A is continuously turned on, and the character code of this "O" is written in the buffer area of the RAM3, and thereafter. The step 206 waits for key input. Therefore, the first of the name "Ohki"
This means that the character "O" can be entered.

Next, regarding the input of the second character "h", this is in the second line of the first group ALPH1 of the alphabet table ALPHT, and in this case, by inputting "O",
The second group ALPH2 of the alphabet table ALPHT is displayed on the display section 83.
The first line of is displayed.

Then, by pressing the left or right cursor key 6L or 6R, as shown in FIG. 17A, "AM" is displayed in the display area 83, and the cursor is moved to the display portion 83H where "H" is displayed. Move the CSR.
At this time, the character "H" at the cursor position is blinkingly displayed on the second character display portion 84B of the display area 84.

Then, the up / down cursor key 6U or 6D is pressed. Then, the processing proceeds from step 206 to step 221 through step 221. In this step 221, the flag CMF is checked. In this case, CMF = 1, so the processing proceeds from step 221 to step 223. Then, in this step 223, all the letters displayed in the display area 83 are moved up and down by one character in the letter table ALPHT (1
It is scrolled by the number of rows).

In this case, if the downward cursor key 6D is pressed, the characters displayed in the display area 83 are displayed as "A ~" in the first line of the alphabet table ALPHT as shown in FIG. 17B. Changed from "M" to "am" in the second line,
If the upward cursor key 6U is pressed,
As shown in FIG. 7C, the characters displayed in the display area 83 are changed from “A to M” on the first line of the alphabet table ALPHT to “(blank symbol) to &” on the third line. Further, the character currently displayed at the position of the cursor CSR is blinked and displayed on the second character display portion 84B of the display area 84.

Then, the process returns from step 223 to step 206.

Therefore, when the downward cursor key 6D is pressed, each time the cursor key 6D is pressed, as shown in FIGS.
The characters displayed in the display area 83 are "AM" →
It repeatedly changes in the normal order such as “a to m” → “(blank symbol) to &” → “A to M”. When the up cursor key 6U is pressed, the display area 83 is pressed each time the cursor key 6U is pressed.
The characters displayed at are repeatedly changed in the reverse order such as "AM" → "(blank symbol) ~ &" → "am" → "AM" → .... Furthermore, the display of the display section 84B also changes in response to this change in display, and the same character as the character displayed at the cursor position blinks on the display section 84B.

Then, in this case, the cursor CSR in the display area 83 is moved to the display portion 83H in which "H" is displayed, and then "am" is displayed in the display area 83. . Then, when the “a to m” is displayed, the cursor CSR is located on the display portion 83H of the “h”.

Therefore, if the enter key 6K is pressed while waiting for key input in step 206, "h" on the display section 84B is continuously lit by steps 241 and 242 in the same manner as in the kana input mode. At the same time, the character code of "h" is written in the buffer area of the RAM 3, and then in step 206, the key input is waited. Therefore, the second with the name "Ohki"
This means that the character "h" can be entered.

Then, thereafter, similarly, the cursor key 6L
By selecting an alphabetic character with ~ 6D, and then pressing the confirm key 6K, the third character "k" of the name "Ohki"
And the fourth letter "i" can be entered.

When all the characters of the name have been input, the registration key 6T is pressed and the process proceeds to step 20.
From 6 to step 207, the process proceeds to step 251, REGF = 1 is set, and in step 252,
This routine 200 ends.

As described above, the alphabet table AL is used as the name.
You will be able to enter the letters in PHT. Further, since the alphabet table ALPHT also includes characters other than alphabetic characters, these characters can be used for the name, and "R &D" or the like can be input as the name.

Alternatively, when the second character "h" of the name "Ohki" is input, it can be input as follows. That is, the left and right cursor keys 6L, 6
Between R and the up and down cursor keys 6U and 6D,
Since there is no priority relationship, after inputting the first character "O", press the up / down cursor key 6U or 6D and display in the display area 83 in the second row ALPH2 of the alphabet table ALPHT. Is displayed. Then, by pressing the left or right cursor key 6L or 6R, the display area 83 is displayed with "a ~" in the second row of the first group ALPH2 of the alphabet table ALPHT.
"m" is displayed, the cursor CSR is moved to the displayed "h", and then the enter key 6K is pressed.

Even in this case, the second "h" of the name "Ohki" can be input, or the left and right cursor keys can be used for not only the second alphabetic character but also the character at all positions. 6L and 6R and the up and down cursor keys 6U and 6D can be input without specifying the operation order.

-3 When entering characters in the numeric table NUMT The key operation is basically the same as when entering characters in the kana table KANAT.
A column of the number table NUMT is selected with L and 6R, and a row is selected with the up and down cursor keys 6U and 6D to specify a target number.

That is, the input of the telephone number is step 11
7 is performed, but when the execution of the routine 200 is started in step 117, step 1
15, 202, and 203, as shown in FIG. 18A,
The numbers in the number table NUMT are displayed in the display area 83, and the number input mode is set.

Then, the left / right cursor key 6L or 6R is pressed. Then, the process proceeds from step 206 to step 231 to step 231.

Then, in this step 231, the flag CMF is checked, and in this case, CMF = 2, so the processing advances from step 231 to step 235, and in this step 235, the cursor CSR is displayed in the display area 83.
Moves left and right by one character (row by one character).

In this case, if the right cursor key 6R is pressed, the display section 83 is displayed as shown in FIG. 18B.
If the cursor CSR displayed on A is moved from “0” on the display section 83A to “1” on the display section 83B and the left cursor key 6L is pressed, as shown in FIG. 18C, The cursor CSR displayed on the portion 83A moves from "0" on the display portion 83A to ")" on the display portion 83M. In addition, the character displayed at the current position of the cursor CSR is the first character display portion 84A of the display area 84.
Flashes on the display. Then, the process is step 2
The procedure returns from step 35 to step 206.

Therefore, when the right direction cursor key 6R is pressed, the cursor CSR is displayed in the display area 8 every time the key is pressed.
3 is repeatedly moved from “0” to “)”. When the left cursor key 6L is pressed, the cursor CSR changes from ")" to "0" in the display area 83 with each press.
Move repeatedly in the direction of. Further, the display of the first character display portion 84A also changes in response to the change in the cursor position, and the number at the cursor position is displayed blinking.

In this way, by pressing the key 6L or 6R, the cursor CSR is moved to the target number (one digit of the telephone number) and the target number is displayed on the display section 84A.

Then, when the cursor CSR moves to the desired number and the desired number is displayed on the display section 84A, the enter key 6K is pressed. Then, in the same way as in the kana input mode, in steps 241, 242, the number displayed on the display section 84A is continuously turned on, and the character code of the number is written in the buffer area of the RAM3, and thereafter. The step 206 waits for key input. Therefore, thereafter, by repeating the above key operation, it is possible to sequentially input each digit of the target telephone number.

When all the digits have been entered and the registration key 6T is pressed, the process proceeds from step 206 to step 207 to step 251 where REGF = 1 is set, and in step 252, this routine 20 is executed.
0 ends.

If the up / down cursor key 6U or 6D is pressed while waiting for key input in step 206, the process proceeds from step 206 to step 221 through step 221. In step 221, the flag CMF is checked. In this case, since CMF = 2, the process proceeds from step 221 to step 223. Then, in this step 223, all the numbers displayed in the display area 83 are displayed in the number table NU.
Scrolls one character of MT up and down (1 row in column direction).

In this case, if the downward cursor key 6D is pressed, the character displayed in the display area 83 is the first character of the numeric table NUMT, as shown in FIG. 18D.
If the line “0-)” is changed to the line “#-×” and the upward cursor key 6U is pressed, FIG.
As shown in F, the characters displayed in the display area 83 are changed from "0" in the first line of the number table NUMT to "_" in the fourth line. Also, the current cursor CSR
The character displayed at the position is blinked in the display area 84.

Then, the process returns from step 223 to step 206.

Therefore, when the down cursor key 6D is pressed, each time the cursor key 6D is pressed, as shown in FIGS.
The characters displayed in the display area 83 are "0)" →
"# ~ X" → "+ ~}" → "_ ~ day" → "0)" → ...
It changes repeatedly in a normal order like. When the cursor up key 6U is pressed, the display area 8
The characters displayed in 3 are "0-)" → "_-day" →
It repeatedly changes in the reverse order such as "+ ~}" → "# ~ x" → "0)" → ....

Then, when the number in any column of the number table NUMT is displayed in the display area 83, the cursor CSR is moved to the number in the displayed column by the left and right cursor keys 6L or 6R, and the confirmation is made. When the key 6K is pressed, similarly, the character code of the numeral at the cursor position is written in the buffer area of the RAM3.

As described above, it is possible to input the numbers in the number table NUMT as the telephone numbers.
In addition, since characters other than numbers are also prepared in the number table NUMT, these characters can also be used for the telephone number, and the telephone number can be input as "03-9301-2963". it can.

-4 Extended Input of Name or Telephone Number In step 113 or step 117, the operation of the character type key 6C is effective even while the name or telephone number is being input. The input mode is kana mode, alphabetic mode, or numeric mode according to the designation of the character type key 6C.

Therefore, kana characters, alphabets and numbers can be mixed in the name and telephone number.
For example, a registration such as "PTC / DI3 SECURE" can be performed. Similarly, phone numbers can be
"F03-9301-2963", "H03-3448
It is also possible to display that these numbers are fax numbers or home telephone numbers by the leading letters "F" and "H" as "-3311".

<< Correcting Characters During Input >> Deleting Characters Input Just Before (Backspace) This is a function of deleting a character when the character is mistakenly confirmed while inputting a name or a telephone number.

That is, if the delete key 6N is pressed during input of a character, the process proceeds from step 206 to step 271 to step 271. In this step 271, the character entered immediately before is deleted, and then the process proceeds to step 206. Return to. Therefore, the correct name or telephone number can be input after that by inputting the correct character.

Modifying Characters This modification includes overwriting, inserting, deleting, etc. That is, if the correction key 6S is pressed during input of a character, the input correction mode is entered, and the process proceeds from step 206 to step 207 to step 281 where the input correction routine 300 is executed.

Since this routine 300 is not directly related to the present invention, its explanation is omitted, but this routine 30
With 0, corrections such as overwriting, insertion, and deletion are performed. Then, when this routine 300 ends, the process returns from step 281 of routine 200 to step 206,
Wait for key input for the next character.

<< Processing Content of Search Routine 400 >> In step 103, the processing content when the search routine 400 is executed is as follows. When you enter the name and phone number of the other party, you can use any kana characters, letters, numbers, or a mixture of them as the name. When you search for the telephone number, enter the other party's name as a keyword. At that time, it is necessary that any of kana characters, alphabetic characters, and numbers can be used as the keyword. Then, such a point is also taken into consideration in the routine 400.

That is, the processing of the CPU 1 is the routine 4
Start from step 401 of 00, then step 4
In 02, the flag CMF is set to CMF = 0, and then the processing proceeds to step 403, and this step 403
In, the flag CMF is checked, and when CMF = 0 (in this case, this is the case), the process proceeds from step 43 to step 404.

Then, in this step 404, as shown in FIG. 19A, for example, the display area 83 of the LCD 8 is displayed.
In the display portions 83A to 83M of the Kana table KANAT corresponding to CMF = 0, the characters "A-A" in the column of KANAT are displayed one by one, and the display portion 83A of the leading "A" is displayed.
The cursor CSR is displayed at.

Further, since the character at the display position of the cursor CSR is "A", the first name starting with "A" among the names and telephone numbers registered in the RAM 4, "Aoki Keisuke" in FIG. 19A. , Are displayed in the display area 84. When the name starting with the character at the cursor position, in this case, the name starting with "A" is not registered, nothing is displayed in the display area 84.

Then, the processing advances to step 407, and in this step 407, the key input is awaited. Therefore, when the power is turned on, the key input is awaited in the kana input mode in the display state of FIG. 19A.

In step 403, CMF = 1
If so, the process proceeds from step 403 to step 405.
Proceed to. Then, in this step 405, for example, as shown in FIG. 22A, the characters “A to M” in the first line of the first group ALPH1 of the alphabet table ALPHT are displayed on the display portions 83A to 83M of the display area 83 of the LCD 8 as one character. Are displayed one by one, and the display section 83A of "A" at the beginning is displayed.
The cursor CSR is displayed at. Also, the character at the display position of the cursor CSR is "A", so if there is a name or telephone number registered in RAM4 that starts with "A",
The first name among them is displayed in the display area 84.

Then, in this state, the processing is step 407.
Proceed to and wait for key input. Therefore, when CMF = 1, it becomes the alphabet input mode.

Further, in step 403, CMF =
If the value is 2, the process proceeds from step 403 to step 40.
Go to 6. Then, in this step 406, as shown in FIG. 23A, for example, the numbers "0" in the first line of the number table NUMT are displayed character by character on the display portions 83A to 83M of the display area 83 of the LCD 8 while being displayed character by character. The cursor CSR is displayed on the display portion 83A of "0" at the head of the cursor. Further, since the character at the display position of the cursor CSR is "0", if the name and telephone number registered in the RAM 4 have names starting with "0", the first name of them is displayed in the display area 84. .

Then, in this state, the processing is step 407.
Proceed to and wait for key input. Therefore, when CMF = 2, the numeral input mode is set.

Switching Character Type of Keyword During Search To switch the type of character that serves as a keyword during search between kana characters, alphabetic characters, and numbers, when waiting for key input in step 404, the character type key 6C is selected. push.

Then, the process proceeds from step 407 to step 408. In this step 408, it is determined that the key input in step 407 is the character type key 6C, and the process proceeds from step 408 to step 411.
Proceed to. Then, in this step 411, the flag
The CMF is incremented by "1", and then the process returns to step 403. In step 411, when CMF = 3 as a result of the flag CMF being incremented, CMF = 0 is changed.

Therefore, when the character type key 6C is pressed, the flag CMF is repeatedly changed as 0 → 1 → 2 → 0 → ... with each press, and the character table corresponding to the value of the flag CMF is displayed in the display area 83. Is displayed and the key input is awaited. That is, each time the character type key 6C is pressed,
The input mode repeatedly changes in the kana input mode → alphabet input mode → numeric input mode → kana input mode → ....

At this time, according to the character type of the input mode, the name starting with the character at the cursor is RAM4.
If registered in, the name is displayed in the display area 84.

Search for Telephone Number In this example, the telephone number search method is as follows: −1 initial search A prefix search (first letter) of the other party's name is used as a keyword to perform a forward match search to find the telephone number. -2. Method of extracting -2 Direct search Two methods are available: a method of extracting the telephone number by performing prefix search using the first two or more characters (character string) of the other party's name as a keyword. In each case, the keyword may be any of kana characters, alphabetic characters, and numbers.

-1-1 Initial Search Using Characters in Kana Table KANAT Here, the name of the intended partner is "Kikuchi Michiko".
Suppose Then, the routine 400 executes step 40.
When starting from 1 and waiting for key input in step 407, CMF = 0, and in the display area 83, for example, as shown in FIG.
KANAT is displayed and it is in Kana input mode.

Since the first character "ki" of the name "Kikuchi Michiko" is in the K row of the Kana table KANAT,
Press the left / right cursor key 6L or 6R. Then, the process proceeds from step 407 to step 408,
In this step 408, the key entered in step 407 is determined, and in this case, the cursor key 6L or 6R in the left-right direction has been pressed, so the process proceeds to step 4
From 08 to step 431.

Then, in this step 431, the flag CMF is checked, and in this case, CMF = 0, so the processing advances from step 431 to step 432, and in this step 432, as shown in FIG. Kana table KANA on the display sections 83A to 83M of
The character in the column of T is displayed, and then, in step 433, the cursor CSR moves in the display area 84 by one character in the left-right direction (in the row direction by one line).

In this case, if the cursor key 6R to the right is pressed, the display section 83 is displayed as shown in FIG. 19B.
If the cursor CSR displayed on A is moved from “A” on the display section 83A to “F” on the display section 83B and the left cursor key 6L is pressed, as shown in FIG. The cursor CSR displayed on the portion 83A moves from "A" on the display portion 83A to "WA" on the display portion 83J. Further, if the name and telephone number registered in the RAM 4 have names that start with the character at the display position of the cursor CSR, the first name of them is displayed in the display area 84. Then, the process returns from step 433 to step 407.

Therefore, when the right cursor key 6R is pressed, each time the cursor key 6R is pressed, as shown in FIGS.
The cursor CSR repeatedly moves the display area 83 from the A line to the W line. When the left cursor key 6L is pressed, the cursor CSR is displayed in the display area 8 with each press.
Repeat 3 to move from row w to row a. further,
The name displayed in the display area 84 also changes in response to this change in the cursor position, and if the name and telephone number registered in the RAM 4 start with the character at the cursor position, the first of them will be the first name. It is displayed in the display area 84.

By pressing the key 6L or 6R in this way, as shown in FIG. 20A, the cursor CSR is moved to the "K" of the target row of the "K".

When such a display state is reached,
Then, press the up / down cursor key 6U or 6D.
Then, the process proceeds from step 407 to step 408. In this step 408, the key input in step 407 is discriminated, and in this case, the up and down cursor keys 6U or 6D are pressed, so the process proceeds to step 408. To step 421.

Then, in this step 421, the flag CMF is checked, and in this case, CMF = 0, so the processing advances from step 421 to step 422. In this step 422, the cursor CSR is displayed in the display area 83. Only the displayed line is scrolled vertically by one character (in the line direction by one column).

In this case, if the downward cursor key 6D is pressed, the display section 83 is displayed as shown in FIG. 20B.
If the character displayed in B is changed from "K" to "K" and the up cursor key 6U is pressed,
As shown in FIG. 20E, the character displayed on the display unit 83A is changed from "ka" to "ko".

The name displayed in the display area 84 also changes in response to the change in the character at the cursor position.
If the name and telephone number registered in M4 have names starting with the character at the cursor position, the first name of them is displayed in the display area 84. The display unit 83A,
The letters "A, Sa ~" displayed in columns 83C to 83M
The display of "a" does not change. Then, the process returns from step 422 to step 407.

Therefore, when the downward cursor key 6D is pressed, each time the cursor key 6D is pressed, as shown in FIGS.
The character displayed at the cursor position (the character displayed on the display unit 83B) is "K" → "Ki" → "K" →
It repeatedly changes in a positive order, such as “ke” → “ko” → “ka” → ... If you press the up cursor key 6U, the character displayed at the cursor position
"Ka" → "Ko" → "ke" → "ku" → "ki" → "ka" → ...
It repeatedly changes in the reverse order. Further, the name displayed in the display area 84 also changes in response to this change in the display, and if the name and telephone number registered in the RAM 4 start with the character at the cursor position, the first name of them Is displayed in the display area 84.

In this way, by pressing the key 6U or 6D, when the target "ki" in the present case is displayed at the cursor position (state of FIG. 20B), next in step 407, the key input is awaited. Enter key 6 when
Press K.

Then, in step 408, it is detected that the confirm key 6K has been pressed in step 407, and the process proceeds from step 408 to step 441. In step 441, as shown in FIG. The name displayed in the display area 84 when the button is pressed (FIG. 20B), that is, the first name starting with “ki” among the names and telephone numbers registered in the RAM 4 is displayed in the display area 83. At the same time, the telephone number corresponding to this name is displayed in the display area 84.

Thereafter, in step 442, it is checked whether or not there is a key input, and if there is no key input, the process proceeds from step 442 to step 443. In this step 443, step 442 is executed following step 441. For example, it is checked whether 1 second has passed, and if not, the process returns from step 443 to step 442.
Therefore, the process proceeds from step 441 to step 442.
21. Steps 442 and 443 are repeated, key input waiting is performed for 1 second, and the display state of FIG. 21A continues for 1 second.

In this case (FIG. 21A), the name of the intended other party is not displayed, so step 44
During the repeated key input waiting period of 2,443, the up / down cursor key 6U or 6D is pressed.

Then, the process proceeds from step 442 to step 446. In this step 446, the key input in step 442 is discriminated, and in this case, the up / down cursor key 6U or 6D is pressed.
The process proceeds from step 446 to step 447.

Then, in step 447, when the downward cursor key 6D is pressed in step 442, the next set of names and telephone numbers among the names and telephone numbers registered in the RAM 4 is retrieved, When the downward cursor key 6D is pressed in step 442, the name and telephone number of the immediately preceding group among the names and telephone numbers registered in the RAM 4 are retrieved, and then the process returns to step 441. .

Therefore, when the down cursor key 6D is pressed, each time the cursor key 6D is pressed, the name and the telephone number registered in the RAM 4 start with the first name and telephone number starting with "ki", and then continue. The registered names and telephone numbers are sequentially displayed in the display areas 83 and 84 one by one. When the up cursor key 6U is pressed, each time the key is pressed, the name and the telephone number registered in the RAM 4 start from the first name and the telephone number starting with "ki" and the previous name. , And telephone numbers are displayed one by one in the display areas 83 and 84 in order.

Then, generally, from the first character and telephone number of the target name, in the present case, the first name and telephone number starting with "ki" of "Kikuchi Michiko", Since the display has started, if you press the cursor key 6D in the down direction, when you press it several times,
As shown in 1B, the name and telephone number of the intended other party are displayed.

Therefore, this means that the telephone number of the other party can be searched using the initials of the name of the kana character as a keyword.

Immediately after this search, steps 442 and 443 are repeated and waiting for key input, but since the name and telephone number of the intended other party have been searched, nothing is done. If you do not enter the key, 1
When the second has elapsed, the process proceeds from step 443 to step 444.

Then, in this step 444,
The telephone number displayed in step 441 (FIG. 21B) is
As shown in FIG. 21C, the display areas 83 and 84 are used to magnify and display in a double vertical size. That is, for example, the display portion 83A and the display portion 84A are continuous in the vertical direction, and when these are combined, there is a display dot of 15 dots (vertical) × 5 dots (horizontal). The first digit of the phone number is displayed, and the second digit and beyond
The display portions 83B, 84B to 83M, 84M are similarly displayed.

In this way, when the name and telephone number of the intended other party are retrieved and no key is input, when one second elapses, the telephone number of the other party is displayed, as shown in FIG. 21C. The display areas 83 and 84 are enlarged and displayed in double vertical size.

Further, when in this display state, the process proceeds to step 445, and in this step 445, the key input is awaited. Therefore, it is possible to make a call to the other party by looking at the enlarged telephone number. If the up / down cursor keys 6U and 6D are pressed while waiting for the key input in step 445, the processing is performed. Since the process proceeds from step 445 to step 446, it is possible to see the name and telephone number before and after the target name and telephone number.

If the enter key 6K is pressed again while waiting for a key input in step 445, the process proceeds from step 445 to step 446 to step 40.
Returning to step 2, the search mode is again in the initial state.

-1-2 Initial Search Using Characters in Alphabet Table ALPHT The key operation is basically the same as the initial search using characters in the Kana table KANAT, and the left and right cursor keys 6L, English table ALPHT by 6R
To select the name of the other party with the up and down cursor keys 6U and 6D to obtain the telephone number.

That is, the routine 400 executes step 40.
When starting from 1 and waiting for key input in step 407, CMF = 0, and in the display area 83, for example, as shown in FIG.
KANAT is displayed and it is in Kana input mode.

Therefore, first, as described above, the character type key 6C is pressed to enter the alphabet input mode (CMF = 1) as shown in FIG. 22A. Then, in the display area 83, the characters "A to M" in the first line of the first group ALPH1 of the alphabet table ALPHT are displayed, and the cursor CSR is displayed in the display portion 83A of "A" at the beginning thereof. To be done.
Also, since the character at the display position of the cursor CSR is "A",
"A" is added to the name and telephone number registered in RAM4.
If there is a name starting with, the first name of them is displayed in the display area 84.

In this state, if the left or right cursor key 6L or 6R is pressed, the process proceeds to step 4
From 07 to step 408, the process proceeds to step 431.

Then, in this step 431, the flag CMF is checked, and in this case, CMF = 1, so the processing advances from step 431 to step 434, and in step 434, the display of the display area 83 is changed to the cursor key 6L or Changed to correspond to 6R.

That is, when the right cursor key 6R is pressed, the cursor CSR displayed on the display section 83A changes from "A" on the display section 83A to "B" on the display section 83B as shown in FIG. 22B. Moving. Further, if the names and telephone numbers registered in the RAM 4 have names that start with the character at the cursor position, the first name among them is displayed in the display area 84. Then, the process returns from step 434 to step 407.

Therefore, each time the right cursor key 6R is pressed, each time the cursor key 6R is pressed, as shown in FIGS.
The cursor CSR moves the display portions 83A to 83M by one character at a time, and if the name and telephone number registered in the RAM 4 have a name starting with the character at the cursor position, the first name is displayed. It is displayed in the area 84.

However, as shown in FIG. 22C, the cursor
When CSR is moved to "M" on the display section 83M at the right end, pressing the cursor key 6R causes the display area 83 to display the alphabet "N" of the second group ALPH2 of the alphabet table ALPHT as shown in FIG. 22D. ~ Z ”is displayed,
The cursor CSR is displayed on the display unit 83 displaying “N”.
Located in A. Further, if the names and telephone numbers registered in the RAM 4 have names that start with the character at the cursor position, the first name among them is displayed in the display area 84.

After that, the right cursor key 6R
Each time is pressed, the cursor CSR moves the display area 83 in the direction from “N” to “Z” by one character, and at the same time, the name and telephone number registered in the RAM 4 are indicated by the character at the cursor position. If there are names that start, the first name of them is displayed in the display area 84.

Then, as shown in FIG. 22E, the cursor
When the right side cursor key 6R is pressed when the CSR is moved to the display portion 83M displaying “Z”, the screen shown in FIG. 22A is displayed.
As shown in, the display area 83 has an alphabetic table ALPH.
The letters "A to M" of the first group ALPH1 of T are displayed, and the cursor CSR is located on the display portion 83A displaying that "A". Further, if the names and telephone numbers registered in the RAM 4 have names that start with the character at the cursor position, the first name among them is displayed in the display area 84.

Therefore, when the right cursor key 6R is pressed, the cursor CSR can be moved in the normal order with respect to the letters "AZ".

When the leftward cursor key 6L is pressed from the display state of FIG. 22A, the display state of FIG. 22A → the display state of FIG. 22E → ... → the display state of FIG. 22D → the display state of FIG. 22C. → ... → Display state of FIG. 22B → Display state of FIG. 22A → Display state of FIG. 22E → ...
The display status changes.

Therefore, by pressing the cursor key 6L to the left, the cursor CSR can be moved in the reverse order with respect to the letters "AZ".

On the other hand, when the up or down cursor key 6U or 6D is pressed while waiting for the key input in step 407, the process proceeds from step 407 to step 408 to step 421, in which the flag CMF is checked. In this case, since CMF = 1, the process proceeds from step 421 to step 423. Then, in this step 423, all the letters displayed in the display area 83 are changed to the letter table AL.
Up and down one character of PHT (one line and column)
Will be scrolled.

For example, if the downward cursor key 6D is pressed in the display state of FIG.
As shown in, the characters displayed in the display area 83 are displayed in the second to the second row from "AM" in the first line of the alphabet table ALPHT.
Change to "a to m" on the line and move the cursor key 6U upward
If is pressed, the characters displayed in the display area 83 are changed from "A to M" on the first line of the alphabet table ALPHT to "(blank symbol) to &" on the third line. Further, if the names and telephone numbers registered in the RAM 4 have names that start with the character at the cursor position, the first name among them is displayed in the display area 84.

Then, the process returns from step 423 to step 407.

Therefore, each time the cursor key 6D in the downward direction is pressed, the character displayed in the display area 83 is changed from "AM" to "am" to "(blank symbol) to & ] → “A to M” ... When the cursor key 6U in the up direction is pressed, the character displayed in the display area 83 is
"AM" → "(blank symbol) ~ &" → "am" →
It repeatedly changes in the reverse order such as "AM" ... Further, in response to the change in the display, if the name and telephone number registered in the RAM 4 have names starting with the character at the cursor position, the first of them is the display area 84.
Is displayed in.

In this way, when the cursor CSR is moved to the desired alphabetic character, the enter key 6K is pressed. Then, the process proceeds from step 407 to step 408 to step 4
Proceed to step 41, and thereafter, as with the case of kana characters, enter key 6

In the display area 83, the numbers of the number table NUMT are displayed, and at the beginning of the display portion 83A of "0",
The cursor CSR is displayed. Further, since the character at the display position of the cursor CSR is "0", if the name and telephone number registered in the RAM 4 have names starting with "0", the first name of them is displayed in the display area 84. .

In this state, if the left or right cursor key 6L or 6R is pressed, the process proceeds to step 4
From 07 to step 408, the process proceeds to step 431.

Then, in this step 431, the flag CMF is checked, and in this case, CMF = 2, so the processing proceeds from step 431 to step 435. In step 435, the display in the display area 83 is changed to the cursor key 6L or Changed to correspond to 6R.

That is, when the right cursor key 6R is pressed, the cursor displayed on the display portion 83A
CSR is “0” on display 83A to “1” on display 83B
If the left cursor key 6L is pressed, the cursor CSR displayed on the display unit 83A moves from “0” on the display unit 83A to “)” on the display unit 83M. Further, if the names and telephone numbers registered in the RAM 4 have names that start with the character at the cursor position, the first name among them is displayed in the display area 84. Then, after that, the process proceeds from step 435 to step 407.
Return to.

Therefore, when the right direction cursor key 6R is pressed, the cursor CSR is displayed in the display area 8 every time the key is pressed.
3 is repeatedly moved in the direction from “0” to “)”, and if the name and telephone number registered in the RAM 4 have names starting with the character at the cursor position, the first name of them is displayed in the display area 84. Is displayed.

When the leftward cursor key 6L is pressed, the cursor CSR repeatedly moves in the display area 83 from ")" to "0" each time the cursor key 6L is pressed. further,
Corresponding to this change in the cursor position, if the name and telephone number registered in the RAM 4 have names starting with the character at the cursor position, the first name of them is displayed in the display area 84.

On the other hand, when the up / down cursor key 6U or 6D is pressed while waiting for the key input in step 407, the process proceeds from step 407 to step 421 to step 421, in which the flag CMF is checked. In this case, since CMF = 2, the process proceeds from step 421 to step 423. Then, in this step 423, all the numbers displayed in the display area 83 are displayed in the number table NU.
Scrolls one character of MT up and down (1 row in column direction).

In this case, if the down cursor key 6D is pressed, the character displayed in the display area 83 is the first character of the numeric table NUMT, as shown in FIG. 23B.
If the line “0-)” is changed to the second line “#-×” and the upward cursor key 6U is pressed, FIG.
As shown in D, the characters displayed in the display area 83 are changed from "0" in the first line of the number table NUMT to "_" in the fourth line. If the names and telephone numbers registered in the RAM 4 have names that start with the character at the cursor position, the first name among them is the display area 8
4 is displayed.

Then, the process returns from step 423 to step 407.

Therefore, when the downward cursor key 6D is pressed, each time the cursor key 6D is pressed, as shown in FIGS.
The characters displayed in the display area 83 are "0)" →
"# ~ X" → "+ ~}" → "_ ~ day" → "0)" → ...
It changes repeatedly in a normal order like. When the cursor up key 6U is pressed, the display area 8
The characters displayed in 3 are "0-)" → "_-day" →
It repeatedly changes in the reverse order such as "+ ~}" → "# ~ x" → "0)" → .... Further, in any case, if the names and telephone numbers registered in the RAM 4 have names that start with the character at the cursor position, the first name among them is displayed in the display area 84.

In this way, when the cursor CSR is moved to the desired character, the enter key 6K is pressed. Then, the process proceeds from step 407 to step 408 to step 4
Proceed to step 41, and thereafter, as with the case of kana characters, enter key 6
The name displayed in the display area 84 when K is pressed, that is, the first name starting with an alphabetic character at the cursor position among the names and telephone numbers registered in the RAM 4 is displayed in the display area 83. At the same time, the telephone number corresponding to this name is displayed in the display area 84. Then, thereafter, step 442 and the subsequent steps are executed as described above.

Therefore, the telephone number of the other party can be searched by using the characters of the numerical table NUMT as a keyword, and
The telephone number of the search result is enlarged and displayed on the display units 83 and 84 in a double-height portrait.

-2 Direct search In step 407, when the user waits for key input, if the direct search key 6H is pressed, the process proceeds from step 407 to step 451 to step 451. Become.

When the cursor keys 6L to 6D or the character type key 6C are pressed, the process proceeds from step 451 to step 452. In this step 452, the key input in step 451 is the cursor keys 6L to 6D.
Is determined to be the character type key 6C, the process proceeds from step 452 to step 453, and then returns to step 451.

In this case, the processing contents of step 453 are as follows.
This is the same as steps 202 to 235 of the routine 200. Therefore, when the character type key 6C is pressed, the character table displayed in the display area 83 is changed in order, and when the cursor keys 6L to 6D are pressed, the pressed cursor is changed. The character at the cursor position is changed according to the key.

In this way, a name in which arbitrary characters are used by using the character type key 6M and the cursor keys 6L to 6D or mixed is input as a keyword. The name being input is displayed in the display area 84.

When the direct search key 6H is pressed again when the input of the name is completed, the process proceeds to step 451.
From step 452 to step 454, in this step 454, the name entered in step 453 or the like is used as a keyword to search the name registered in the RAM 4 for a prefix match, and the target name and telephone number. Is taken out. Then, the process proceeds to step 441.

Therefore, thereafter, as described above, the telephone number of the other party can be searched by prefix matching of the name, and the telephone number of the search result is displayed in double-width vertically.

Correction of input name or telephone number This is a case where the name or telephone number already registered in the RAM 4 is corrected or changed.

In this case, by the search method described above,
Display area 83 for the name and telephone number to be corrected,
84 is displayed. Then, in step 407, when the key input is awaited, the correction key 6S is pressed.

Then, the processing proceeds from step 407 to step 408 to step 461, in which the display of the name or telephone number is corrected in the same manner as the correction of the name or telephone number at the time of inputting, and thereafter, The correction result is registered in the RAM 4. At the time of this registration, the contents of RAM 4 are sorted. Then, when the correction in step 461 is completed, the process returns to step 407.

Transition to Name and Telephone Number Input Mode This is a case of transition from the search mode to the name and telephone number input mode described above. In this case, a key input wait is made in step 407. Then, the mode key 6M is pressed as described above. Then, the process proceeds from step 407 to step 408. Then, in this step 408, it is judged that the key input in step 407 is the mode key 6M, and the processing advances from step 408 to step 471, and in this step 4
At 71, the routine 400 ends. Therefore, the process proceeds from step 103 of routine 100 to step 111, which is in the name and telephone number input mode as described above.

<Other Example> In the above description, the telephone number is enlarged and displayed one second after the name and telephone number of the other party is displayed without performing any special key operation. The enlarged display may be performed only when the enlarged display is designated in advance, or when a predetermined key operation is performed after the name and telephone number of the other party are displayed. For that purpose, whether or not the enlarged display is designated is checked, and only when the designation is made, step 444 may be executed.

Further, in the above description, in the case of direct search, when the input keyword prefix-matches the target name, the name and telephone number are displayed. Alternatively, the name and the telephone number can be displayed when there is an exact match. Furthermore, when the search keyword or the registered name includes alphabetic characters, the search can be performed without distinguishing between uppercase and lowercase letters.

Also, when registering names and telephone numbers in the RAM 4, do not sort them in an ioweo order. At the time of retrieval, all the corresponding names and telephone numbers are taken out as retrieval results, and these are operated by the cursors 6U and 6D. Accordingly, it is possible to display the sets one by one in order.

[0202]

According to the present invention, it is easy to understand the desired character selection. Moreover, this character can be selected only by the four cursor keys 6L to 6D. Also,
It is not necessary to repeat the operation of searching for the corresponding key, determining the character to be input with the key, and confirming the character on the display unit as in the conventional case, and the operability is also good from this point.

Further, the size and arrangement of the key 6 can be made ergonomic without being restricted by the size and arrangement of the key 6. Therefore, the characters can be smoothly input and can be input with one hand. Alternatively, it can be input without being influenced by the arm.
