Abstract

PURPOSE:To improve the utility and to save the memory capacity by replacing a received message into a required sufficient message, storing the message again into a storage means and saving an excess part. CONSTITUTION:A selective call signal and a message received by an antenna 101 are fed to a control section 106 and the message is stored in a memory 105. Then the message stored in the memory 105 is displayed on a display section 108 by depressing a display switch 114. When part of the message is changed, a message change switch 116 is depressed to allow the control section 106 to send a change start signal and a bead character of the message on the screen is surrounded by a cursor. In the case of changing the character, the character in the cursor is changed till the character in the cursor is a desired character through the depression of the switch 116. Then a new character is stored in the memory 105. When the character is eliminated, the cursor is matched and a character decision switch 119 is depressed.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a wireless selective calling receiver with a display, and in particular, to a wireless selective calling receiver with a display so that a received message stored in the memory of the receiver can be edited after receiving it. This invention relates to a radio selective calling receiver with display.

[Prior Art] In recent years, the functionality of wireless selective calling receivers with display has increased, and the content of messages that can be received has expanded from simple information such as telephone numbers to a mixture of ``Kanji'', ``Kana'', and ``Numbers''. There is a tendency to diversify into complex text information.

In this type of conventional radio selective calling receiver with display, the received message is stored in a part of the memory of the radio selective calling receiver with display, and the carrier can operate the switch as necessary. Read the received message again on the LCD (Li
I was checking the received message by displaying it on the QUID Cr1stal Display.

Additionally, it was designed to have a function that allows you to delete messages that are no longer needed.

[Problems to be Solved by the Invention] The above-described conventional radio selective calling receiver with display stores the received message as it is in a part of the memory, and when checking the received message, reads out the message and displays it on the display section. Since the content of the received message is insufficient, or there are unnecessary parts, there is a problem in that it is not possible to add or delete messages. .

[Means for Solving the Problems] The present invention has been made in view of the above-mentioned problems, and it replaces a received message with a necessary and sufficient message so that it can be stored again in a storage means, and also replaces a received message with a necessary and sufficient message. The purpose is to save the memory capacity of the storage means by erasing unnecessary parts for messages that require many parts.To achieve this purpose, a selective calling signal and a message are received and stored in the memory. A storage means for storing, a display means for sequentially reading out a plurality of stored messages and displaying them on a display, a changing means for reading out the messages stored in the storage means and changing the contents, and a message changed by the changing means. and re-storage means for replacing the message with the message before the change and re-storing it in the storage means.

[Example] Embodiments of the present invention will be described below based on the drawings.

FIG. 1 is a block diagram showing an embodiment of a wireless selective calling receiver with display according to the present invention.

In FIG. 1, selective calling signals and messages are received by antenna 101. In FIG. The selective calling signal and message received by the antenna 101 are transmitted to the radio section 1.
02, where it is amplified and demodulated. The demodulated signal is waveform-shaped by the waveform shaping circuit 103 so that it can be read by a decoder in the control section 106, and then supplied to the control section 106. The control unit LO6 controls verification of the selective call signal, output of a light emission drive signal, speaker drive signal, and display drive signal based on the input state of the switch, and data exchange with the memory 105.

The display drive signal output by the control unit 106 is transmitted to the display drive unit 10.
7, and the display drive section 107 drives the display section 108 based on the display drive signal. Further, the light emission drive signal output by the control unit 106 is supplied to the light emission drive unit 109, and the light emission drive unit 109 turns on, turns off, and blinks the light emission unit 110. Furthermore, the speaker drive signal output by the control unit 106 is supplied to the speaker drive unit 111, and the speaker drive unit 111 operates the speaker unit 11 based on the speaker drive signal.
Drive 2.

The selective call signal verification performed by the control unit 106 is performed between the received selective call signal and the selective call signal stored in advance in the ROM 113. For that purpose, ROMI 13
is an ID-ROM in which a selective call signal is stored in advance.

The control unit 106 includes a display switch 114 to a character determination switch 11 so that the user can select the control operation.
9 switches are connected.

The switches from display switch 114 to character determination switch 119 each have the following functions.

The display switch 114 is a switch for selecting whether or not to display on the display unit 108. Message switch 115
is a switch that sequentially displays messages stored in the memory 105.

The message change switch 116 is a switch for sending the start and end of message editing to the control unit 106 as a control signal. Cursor movement switch 11
7 is a switch for moving a cursor surrounding the characters desired to be changed during message modification work. The character change switch 118 is a switch that sequentially displays one character from among the characters currently displayed in the area where the cursor is located in order to change one character surrounded by the cursor and select an input character. It is. The character determination switch 119 is a switch for determining to replace the newly displayed character by the character change switch 118 with the old character and storing the replaced character in the memory 105 again.

Next, the operation of the embodiment of the wireless selective calling receiver with display according to the present invention will be explained with reference to FIGS. 2(a) and 2(b). FIGS. 2(a) and 2(b) are flowcharts illustrating the operation of an embodiment of the wireless selective calling receiver with display according to the present invention.

In FIG. 2(a), it is assumed that when the program starts, time has elapsed since the calling signal and message were received, and the message has already been stored in the memory 105.

After the start (step 201), if you want to check the display, press the display switch 114 (step 202), and one of the messages stored in the memory 105 will be displayed on the display section 108 (step 202). 205).

If the displayed message is different from the message to be searched, by pressing the message scroll switch (step 207), the messages stored in the memory 105 are repeatedly read out in sequence until the message to be searched is displayed. (Steps 205 to 207).

When the message to be searched is displayed, if a part of the message is to be changed (step 208), the message change switch 116 is pressed (step 210) and a change start signal is sent to the control unit 106. At the same time, the first character of the message on the screen is surrounded by a cursor to notify the user that the message has started to be changed (step 211).

Note that if the message is not to be changed, the display of the message is turned off (step 209) and the process returns to the start.

When the message change switch 116 is pressed (step 210), editing operations such as changing, deleting, and adding can be performed for each character constituting the message, and when the cursor is at the first character of the message (step 21
1) If the cursor is not at the character to be changed, such as when changing the third character from the beginning, the cursor is moved when the cursor movement switch 117 is pressed (step 213) (step 214). Repeat until you reach the desired character.

After moving the cursor to the character to be changed, different operations are performed depending on the processing (steps 215, 219, and 223).

First, in the case of character change to insert a new character in place of an old character (step 223), by pressing the message change switch 116, the characters in the cursor are changed until the character in the cursor becomes the desired character. Changes are made (steps 224 and 225). When the desired character is displayed within the cursor, the character determination switch 119 is pressed (step 226). When the message change switch 116 is pressed, the control unit 106 sends the message to the memory 105.
A data signal is sent to the memory 105, and new characters are stored in memory 105 in place of the old characters. At the same time, the cursor moves to the next character (steps 227 to 228).
.

Second, when entering (inserting) a character between a specific character in a message and the character immediately following it (step 215), do as follows.

When the cursor is aligned with the next character of the part to be inserted, the character change switch 118 changes the display within the cursor to a predetermined special character having the meaning of "inserting one character" (step 216). When this display appears and the character selection switch 119 is pressed (step 217), a space is inserted between the character initially displayed in the cursor and the next character in the message.

As a result, it becomes possible to input characters into the newly created space.

Third, if you want to delete a specific character in a message and continue the message after the character after that character to the character immediately before the character to be deleted (step 219), do the following: .

Align the cursor with the character you want to delete, and use the character change switch 118 to change the display within the cursor to a predetermined special character that has the meaning of "delete one character" (
Step 22o). When the character determination switch 119 is pressed when the display appears (step 221), the character at the cursor is deleted.

When the message change is completed by repeating the above operations (step 229), the message change switch 116 is pressed again (step 230), and the control unit 1
At 06, a change completion signal is sent, the cursor on the screen disappears, and the message editing operation is completed.

In this way, by replacing the received message with a necessary and sufficient message and storing it again in the memory 105, convenience is ensured.

Furthermore, since a message with many unnecessary parts can be stored in the memory 105 by erasing the unnecessary parts, it is possible to save the memory capacity of the memory 105.

[Effects of the Invention] As explained above, the present invention provides a storage means for receiving a selective call signal and a message and storing the received message in a memory;
a display means for sequentially reading out a plurality of stored messages and displaying them on a display; a changing means for reading out the messages stored in the storage means and changing the contents; and converting the message changed by the changing means into the message before the change. Since the structure is provided with a restorage means for replacing the message and restoring it in the storage means, the person carrying the radio selective call receiver with display can replace the received message with a necessary and sufficient message and restorage it in the storage means. Therefore, it is very convenient, and it is possible to save the memory capacity of the storage means by erasing the unnecessary parts of a message that has many unnecessary parts.
