By 0, the operation mode of the receiving circuit 12 and the transmitting circuit 17, the channel used, and the like are set. Further, when data such as a message transmitted from the partner machine is output from the receiving circuit 12, this is taken in by the microcomputer 20. Further, when data such as a message is output from the microcomputer 20, the data is supplied to the transmission circuit 17 and transmitted to the partner device.

The ROM 21 is provided with a message editing routine 100 shown in FIG. 3, for example, as a part of the program written in the ROM 21. Further, the memory 24 is a ROM capable of electrically writing data, or, although not shown, a RAM backed up by a battery, that is, the memory 2
4 is non-volatile so that written data can be held even when the power is turned off.

A message to be sent to the other device is prepared in this memory 24. Therefore, for example, a message table DNGN as shown in FIG. 2 is prepared. That is,
In this example, the table DNGN has 10 areas A0.
Each area Ai (i = 0 to 9) has
Each has a capacity of 7 characters (7 bytes), and a message is written in, for example, a JIS code.

Characters that can be used for messages are katakana, alphabet, which can be expressed by a 1-byte character code.
Numbers, some symbols. Further, the message has a fixed length of 7 characters (7 bytes), and when it is 6 characters or less, a blank symbol is supplemented to unnecessary portions.

Further, a message number pointer MSGP is prepared for the table DNGN. This pointer MSGP is edited (and transmitted) from the areas A0 to A9 of the table DNGN.
The message or the area AMSGP that is the subject of the instruction. For example, as shown in FIG. 2, if MSGP = 1, this indicates area A1, and the message "Tokyo" in this area A1 is the object of editing.

The message number pointer MSGP is held at a predetermined address in the memory 24, and the message used for the previous editing (or transmission) becomes the first candidate for the next editing (or transmission). It is something that is done.

Further, the display controller 26
When the character data to be displayed is supplied, the character data is converted into a display signal and output to the LCD 30. The LCD 30 supplies the character data supplied to the display controller 26. The character corresponding to is displayed.

FIG. 4A shows an example of a display mode when a message is displayed on the LCD 30, and this figure shows the case where MSGP = 1. That is, the LCD 30 has a display area for eight digits, and the value "1" of the message number pointer MSGP is displayed as the message number 31 in the display area of the first digit (left end) of the second digit to the eighth digit. The pointer MSGP is displayed in the digit display area.
The data "Tokyo (the blank symbol after the sixth character)" in the area A1 designated by is displayed as the message 32.
Reference numeral 33 is an underlined cursor.

Further, in FIG. 1, 41 to 4N are various operation keys, all of which are non-lock type push switches. Then, as keys related to the message, the feed key 41, the + key 42, and the-key 4
3. There are cursor keys 44. However, these key 4
1 to 44 may be used for other purposes depending on the operation mode.

In such a configuration, rewriting of the message prepared in the memory 24 is performed as follows by the CPU 21 executing the routine 100.

That is, when the feed key 41 is pressed while the transceiver is in the standby state, this is notified to the CPU 21, and the processing of the CPU 21 is executed in step 1 of the routine 100.
Starting from 01, then in step 102, the message number pointer MSGP is restored from the memory 24, and subsequently in step 103, the cursor pointer XPOS is initialized to "0". This pointer XPOS is LCD3
When the cursor 33 is displayed at 0, it specifies the display digit position, and the cursor 3 is displayed at the digit position of the value (XPOS + 1).
3 is displayed. Therefore, 0 ≦ XPOS ≦ 7, and in the case of FIG. 4A, XPOS = 0.

Next, in step 104, the table DN
Of the GN, the message data is read from the area AMSGP designated by the message number pointer MSGP, and the read message data is transferred to the display controller 26. The pointers MSGP and XPOS are also supplied to the display controller 26.

Therefore, if the pointer MSGP returned in step 102 is MSGP = 1, the LCD 30 displays the message number 31 of "1" according to the value of the pointer MSGP in the first digit, as shown in FIG. 4A. Is displayed and the table DNGN
Since the data of the message "Tokyo" of the area A1 is supplied to the display controller 26, the message 32 of "Tokyo" is displayed after the second digit. Also XP
Since OS = 0, the cursor 33 is displayed in the first digit, that is, below the message number 31.

Subsequently, the process proceeds to step 105, and in this step 105, the key input of the keys 41 to 44 is waited. Therefore, (1) when selecting the message to be edited ・ ・ ・ key 42, 43 (2) when changing the digit position of the character to be edited ・ ・ ・ key 44 (3) when selecting the character to be the edited result・ ・ ・ Keys 42, 43 (4) To end editing ・ ・ ・ Select the keys 41 to 44 according to the purpose, like the key 41. For the above items (1) and (3), press key 4
Although 2 and 43 are used in common, the desired result can be obtained as described below.

If any of the keys 41 to 44 is pressed while waiting for key input in step 105,
The process proceeds to step 106, and in this step 106, the key pressed in step 105 is the keys 41 to 4
It is discriminated which of the four is 4 and the processing of the above items (1) to (4) is executed as follows according to the discrimination result. The following items (1) to (4) correspond to the above items (1) to (4).

(1) When the + key 42 or-key 43 is pressed (part 1) When the + key 42 or-key 43 is pressed while waiting for the key input in step 105, the process proceeds to step 1
From 06, the process proceeds to step 111. Then, in this step 111, whether or not XPOS = 0, that is,
When the key 42 or 43 is pressed, it is checked whether the display digit position of the cursor 33 is the display digit position of the message number 31.

As a result of this check, XPOS = 0
If the display digit position of the cursor 33 is the display digit position of the message number 31, the process proceeds from step 111 to step 1
12. In step 112, the pointer MS
The value of GP is incremented or decremented by "1".

That is, in this case, since the + key 42 or the-key 43 is pressed in step 105 and the process proceeds to step 112, if the + key 42 is pressed in step 105, the pointer MS
The value of GP is incremented by "1" and step 10
If the-key 43 is pressed in 5, the value of the pointer MSGP is decremented by "1".

Next, the process proceeds to step 113, where
At 13, the result of step 112 is checked,
When MSGP <0, MSGP> 9 so that MSGP = 0
In case of, the value of the pointer MSGP is corrected so that MSGP = 9. When 0 ≦ MSGP ≦ 9, nothing is done.

The process then returns to step 104 following step 113. Therefore, in the table DNGN, the message of the area AMSGP according to the result of the increase / decrease of the pointer MSGP in step 112 (or the correction result of the pointer MSGP in step 113) is the LCD 30.
Is displayed in.

Therefore, for example, as shown in FIG.
When the cursor 33 is displayed at the digit position of the message number 31 and waiting for key input (step 105), each time the + key 42 is pressed, as shown in FIG. 4B or 4C. Then, the messages prepared in the table DNGN are displayed in the normal order on the LCD 30 together with the message numbers. When the-key 43 is pressed, each time the key 43 is pressed, as shown in FIG. 4C → FIG. 4B → FIG.
The message prepared in DNGN, along with the message number,
They are displayed in reverse order on the LCD 30.

In this way, it is possible to select and display an arbitrary message from the messages prepared in the table DNGN in the forward or reverse order. In addition, this displayed message is
As will be described later, it is a target of editing.

(2) When the cursor key 44 is pressed When the cursor key 44 is pressed while waiting for the key input in step 105, the process proceeds from step 106 to step 121. Then, in step 121, the value of the pointer XPOS is incremented by "1", and then in step 122, whether XPOS = 8, that is, the key 44 is pressed, the cursor 3
It is checked whether the display digit position of 3 is outside the display area, and when it is within the display area (XPOS = 0 to 7),
The process returns to step 104.

Therefore, for example, the state (XPOS =
If you press the cursor key 44 from 0), XPOS = 1
Therefore, as shown in FIG. 4D, the cursor 33 moves to the first digit position of the message 32 (the second digit of the display area of the LCD 30). Then, when the cursor key 44 is pressed again from the state of FIG. 4D, XPOS = 2, so that the cursor 33 moves to the message 3 as shown in FIG. 4E.
It moves to the second digit position of the second digit (third digit of the display area of the LCD 30).

Thus, each time the cursor key 44 is pressed, the displayed digit position of the cursor 33 moves right by one digit each time the cursor key 44 is pressed.

When the cursor 33 is displayed at the seventh digit (the last digit of the LCD 30) of the message 32,
Although XPOS = 7, when the cursor key 44 is pressed in this state, XPOS = 8, so the process returns from step 122 to step 103, and XPOS = 0. Therefore, the cursor 33 has the same message number 31 as in FIGS.
It will return to the display digit position of (XPOS = 0).

In this way, each time the cursor key 44 is pressed, the displayed digit position of the cursor 33 moves right by one digit each time the cursor key 44 is pressed, and when the cursor 33 moves to the last digit, the next digit returns to the first digit. Move right digit by digit. Therefore, by pressing the cursor key 44, the cursor 33
Can be moved to any display digit position.

When the cursor 33 is displayed for the message 32 (when XPOS = 1 to 7), the next
As described in section (3), the character at the digit position where the cursor 33 is displayed is the object of editing. That is, message 32
If there is a character to be edited, the cursor key 44 is pressed several times to move the cursor 33 to the digit position of the character to be edited.

(3) When the + key 42 or the-key 43 is pressed (No. 2) When the + key 42 or the-key 43 is pressed while waiting for the key input in step 105, it is described in the item (1). As described above, the process proceeds from step 106 to step 111, and whether or not XPOS = 0, that is, whether the display digit position of the cursor 33 is the display digit position of the message number 31 when the key 42 or 43 is pressed. Is checked.

In this case, by executing the item (2), the cursor 33 moves the digit position of the message 32 (XPOS = 1 to 1).
7). For example, as shown in FIG.
It is assumed to be at the digit position of the second digit (third digit of the display area of the LCD 30) of.

Then, the process proceeds from step 111 to step 131, and in step 131, the message number pointer MSGP in the areas A0 to A9 of the table DNGN.
Is set in the area AMSGP designated by, and the address A (MSGP, XPOS) of the digit position (the digit position in the message 32) indicated by the cursor pointer XPOS in the area AMSGP is set.

For example, as shown in FIG. 4E, the LCD 30
Is displayed as the message 32, and the second digit of the message 32 (the third area in the LCD 30 display area) is displayed.
When the cursor 33 is displayed at the digit position of (digit), MSGP = 3 and XPOS = 2, so the second character “Aomori” of the message “Aomori” in the fourth area A3 of the table DNGN is displayed. The address A (3,2) in which the character code C (3,2) of "e" is written is set.

Then, the process proceeds to step 132, where the value of the character code C (MSGP, XPOS) of the address A (MSGP, XPOS) set in step 131 is incremented or decremented. .

That is, in this case, since the + key 42 or the-key 43 is pressed in step 105 and the process proceeds to step 132, if the + key 42 is pressed in step 105, step 1
The value of the character code C (MSGP, XPOS) of the address A (MSGP, XPOS) set at 31 is set as the character code of the next character. If the-key 43 has been pressed in step 105, the value of the character code C (MSGP, XPOS) of the address A (MSGP, XPOS) is set as the character code of the previous character.

For example, the value of the character code C (MSGP, XPOS) of the address A (MSGP, XPOS) specified in step 131 is
In the case of the character code of "o", if the + key 42 is pressed, the character next to "o" is "ka", so the value of the character code of "ka" is set, and the-key 43 is pressed. If it has been pressed, the character before "o" is "e", so the character code value of this "e" is used.

Then, the process returns to step 104.

Therefore, in the state of FIG. 4E, the + key 42
When is pressed, since the cursor 33 is located at the digit position of the character “o” in the message 32, the character “o” is changed to the next character “ka” as shown in FIG. 4F. When the + key 42 is pressed again in this state, the character "ka" at the cursor position is changed to the next character "ki" as shown in FIG. 4G. Thus, when the + key 42 is pressed, the character at the digit position where the cursor 33 is displayed is changed in the normal order.

Further, for example, in the state of FIG. 4G, the-key 4
If you press 3, move the cursor to the digit position of the character "ki".
4F, the character "ki" is changed to the previous character "ka" as shown in FIG. 4F, and in this state, the-key 4 is pressed again.
When 3 is pressed, the character "K" at the cursor position is changed to the previous character "O" as shown in FIG. 4E. Thus, when the-key 43 is pressed, the character at the digit position where the cursor 33 is displayed is changed in reverse order.

In this case, the type and order of characters (in normal order) are katakana (aiueo order) → "".
→ "゜" → "(blank)" → various symbols → numbers → alphabet → katakana →….

Therefore, when the cursor 33 is displayed at the digit position of the message 32, if the + key 42 or the-key 43 is pressed, the character at the digit position where the cursor 33 is displayed is freely changed. be able to. Also,
The message data resulting from the change is held in the area AMSGP under the table DNGN.

(4) When the feed key 41 is pressed When the feed key 41 is pressed, the process proceeds to step 106.
To step 141, the message number pointer MSGP is saved in the memory 24 in step 141, and then the routine 100 is ended in step 142. The message number pointer MSGP saved in step 142 is restored from the memory 24 in step 102 when the message of the table DNGN is selected by editing or transmitting the message next time, for example, when the routine 100 is executed next time. To be done.

The above is the processing contents and the processing result of the routine 100 for the operation of the keys 41 to 44.

Therefore, when editing the message of the table DNGN, as shown in item (A) (1), the + key 42 and the-key 43 are used.
To select a message to be edited (FIGS. 4A to 4C). (B) As shown in item (2), the digit position of the character to be edited is selected by the cursor key 44. (C) As shown in item (3), + key 42 and-key 43
To select the required character. (D) Repeat the operations of (B) and (C) to obtain the desired message (Fig. 4D-K). (E) As shown in item (4), the editing is completed by the feed key 41. And it is sufficient.

When transmitting a message prepared in the table DNGN in this way, the following may be done. That is, (a) put the transceiver in transmit mode. (B) Press the feed key 41. → A message is displayed on the LCD 30. (C) Use + key 42 and-key 43 to select the message to be transmitted. (D) Press the send key among the keys 41 to 4N. → The selected message is sent. (E) Put the transceiver in standby mode. And it is sufficient.

As described above, the message of the table DNGN can be edited to any content. In this case, the message 32
Since the message number 31 is associated with, when the cursor 33 is displayed at the digit position of the message number 31 as shown in FIGS. 4A to 4C, it is prepared in the table DNGN by the + key 42 and the-key 43. You can select a message. Then, as shown in FIGS. 4E to 4G, when the cursor 33 is displayed at the digit position of the message 32, the character at that digit position can be changed. Further, the digit position of the cursor 33 can be freely changed by the cursor key 44.

Therefore, since the operation system for selecting the message and editing the character in the message is unified,
Easy key operation and easy to use.

Moreover, the keys 41 to 43 are keys that are also used when transmitting a message as described above, and the only key newly required for editing a message is the cursor key 44. The cursor key 44 is also a key for rightwardly moving the cursor 33, and is also a key for confirming the character at the cursor position up to that point. Therefore, also from these points, the number of keys is small, which is advantageous.

In the above description, when the characters of the message 32 are edited, if the key 42 or the key 43 is operated, it is changed to the character next to or before the character up to that point. When changing in the order of
It is also possible to change the order from "A" to the normal order or from "Z" to the reverse order.

Further, in place of the + key 42, the-key 43 and the cursor key 44, a rotary encoder and a switch which is turned on / off when the knob of this rotary encoder is pressed are provided, and the knob is turned clockwise or counterclockwise. It is also possible to carry out the processing when the key 42 or 43 is pressed, and to carry out the processing when the knob is pressed or the key 44 is pressed, every time when it is turned clockwise by a predetermined angle.

Furthermore, the cursor 33 is also displayed by reverse display or blinking display of the characters of the message number 31 and message 32.
It can also be realized. Also, message number 31 and message 3
It is also possible to display 2 and 2 in two lines.

Further, in the above description, the present invention is applied to a message editing device for transmitting in a specific low power transceiver, but it is displayed on them in an electronic notebook, an electronic telephone directory, an MD recorder, a CD player and the like. The present invention can also be applied to an editing device for inputting or editing a character string to be edited.
