[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a selective call receiver, and more particularly to a selective call receiver for assisting transmission by a telephone to the selective call receiver.

[0002]

2. Description of the Related Art The selective call receiver currently in use is
It has become possible to send a large amount of data to the recipient by mixing the alphanumeric and kana symbols, and its utility value is increasing. When sending a message to the selective call receiver, the numeric keys of the telephone are used, and a predetermined message is transmitted to the selective call receiver by the combination of the numeric keys.

For example, when a user wants to send a numeral, a numeral message can be sent by selecting the numeral to be sent from the numeral keys of the telephone and pressing the key. Also,
If you want to send a symbol, katakana, or alphabet as a message, two digits are assigned to each character, so you can enter the combination of these two digits using the Can send messages. Currently, above 2
About 100 kinds of symbols, alphanumeric characters, and kana characters can be transmitted by combining digit numbers.

[0004]

As described above, when transmitting a message text composed of alphanumeric and kana symbols, it is necessary to select a combination of numbers corresponding to the message text. For this purpose, you can find the number corresponding to each character that makes up the message from the correspondence table,
For example, a predetermined fixed message text is sequentially called on the LCD screen and the numbers displayed simultaneously are input by the number keys of the telephone.

Therefore, the above-mentioned conventional method is inconvenient because, when transmitting a message to the selective call receiver, it is necessary to select a combination of numbers corresponding to respective characters of the message by a very complicated procedure. There was a problem. Further, in the method of calling a predetermined message text on the LCD screen, it is possible to easily know the combination of numbers, but there is a problem in that the number of message texts is limited and it is not possible to handle arbitrary messages.

The present invention has been made in view of the above-mentioned conventional problems, and an object thereof is to input a numeric value for an arbitrary message when inputting a message to be sent to a selective call receiver using a numeric key of a telephone. Another object of the present invention is to provide a selective call receiver that can display the combination on the display unit and facilitate the transmission operation.

[0007]

In order to achieve the above object, the present invention comprises a receiving unit for receiving a calling signal and a display unit for displaying a message corresponding to the received calling signal. A selective call receiver, comprising: a character input unit for inputting characters displayed on the display unit; and a telephone for transmitting the characters input from the character input unit to the selective call receiver by the telephone. And a conversion unit for converting into numbers to be input by a key, and the characters and the converted numbers are displayed on the display unit.

[0008]

According to the above construction, when a message to be transmitted is inputted from the character input section, the converting section converts it into a numeral to be inputted by the key of the telephone and the numeral is displayed together with the message on the display section. Can be done easily.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of a selective call receiver according to the present invention. In FIG. 1, the receiving unit 1
When the call signal is received by 0, a message is displayed on the LCD 12 as a display unit in response to the call signal. These messages have been sent by the sender by entering a predetermined number from the number keys on the telephone.

Further, from the character input section 14, it is possible to input symbols, alphabets, numbers and kana characters,
These characters are displayed on the LCD 12 via the conversion unit 16. In the conversion unit 16, conversion into numbers corresponding to these characters is also performed at the same time, and the characters are displayed together with the LCD.
12 is displayed. These numbers are numbers to be input from the number keys of the telephone when transmitting each character input from the character input unit 14 as a message to another selective call receiver.

The combination of these message texts and the numbers converted by the conversion unit 16 is stored in the memory 18, and the stored contents can be displayed again on the LCD 12.

Next, the operation of the selective call receiver shown in FIG. 1 will be described.

When a person who possesses the selective call receiver transmits a message to another selective call receiver, he or she inputs a combination of numbers corresponding to the message from the numeric keys of the telephone as in the conventional case. There is a need. At this time, when a desired message is input character by character from the character input unit 14, each time one character is input, the conversion unit 16 converts it into a combination of numbers to be input from the number keys of the telephone.
Then, the characters input from the character input unit 14 and the conversion unit 1
Both of the numbers converted by 6 are displayed on the LCD 12.

Therefore, when inputting a message from the numeric keys of the telephone, the complicated work of reading the combination of the numbers corresponding to the characters of the message from the correspondence table becomes unnecessary. Further, since the conversion from letters to numbers is performed character by character, it is not necessary for the contents of the message to be a fixed sentence, and it is possible to carry out the conversion of the message having arbitrary contents.

As described above, the combination of the input message text and the converted numeral is the memory 18
This is very convenient when you send the same message next time.

FIG. 2 shows a flowchart for converting and displaying message texts into numbers by the selective call receiver shown in FIG.

Normally, the clock mode is set and the LCD
The time is displayed at (S1). When inputting a message, the mode input key is used to switch to the message input mode (S2).

In the message input mode, message characters are input character by character from the character input unit 14 (S
3).

The characters input from the character input unit 14 are converted into numbers by the conversion unit 16 (S4).

The input characters and the converted numbers are LC
It is displayed on D12 (S5).

The input characters and the converted numbers are recorded in the memory 18 (S6).

Next, it is judged whether or not the mode shift key is pressed, and if not pressed, the state of waiting for the input of the message character is entered (S7).

When the mode shift key is pressed, the mode shifts to another mode, for example, the clock mode (S8).

In the message input mode of S2, when the mode shift key is pressed, it is possible to shift to the clock mode again (S9).

FIG. 3 shows a flowchart of changes in the screen display of the LCD when the mode input key is pressed to switch to the message input mode.

Normally, the watch mode is set (S1).
0).

When the mode shift key is pressed to shift to the message input mode, the previously input message stored in the memory 18 is displayed on the LCD 12 together with the converted numbers. In this embodiment, katakana characters are displayed (S11).

When the content of the previous message is unnecessary, the previous message can be cleared by the clear button. You can also modify the previous message if necessary. The state in which the contents of the previous message are cleared will be described below (S12).

For example, when the "A" key of the input keys of the character input section 14 is pressed, the character "A" is displayed on the LCD 12 (S13).

Subsequently, the conversion unit 16 converts the number into a number corresponding to the alphabet A, and this number is displayed on the LCD.
12 is displayed (S14).

When the characters are subsequently input, the characters are converted into numbers, and the characters and the converted numbers are displayed on the LCD 12. In this embodiment, an example in which letters A to I are input is shown (S
15).

The last alphabet I mentioned above can be changed to Z, and the conversion number is also changed from 29 corresponding to I to 66 corresponding to Z. This is performed by moving the cursor to the position of the alphabet I and performing an input operation of the alphabet Z. Note that insertion or deletion can be performed in addition to overwriting. By this operation, it is possible to change part of the contents of the previous message recorded in the memory without erasing the entire contents (S16).

FIG. 4 to FIG. 8 show the flow of hardware operation when a character is input in the message input mode.

FIG. 4 shows a state in which the alphabet A is input by the input keys of the character input unit 14.

As shown in FIG. 5, the input character A is stored in the memory 1 by the CPU constituting the conversion unit 16 and the like.
8 is recorded.

Next, the CPU displays the character A on the LCD 12 as shown in FIG.

Further, the CPU, as shown in FIG.
The input letter A is converted into 16 which is the corresponding number.

The converted numeral 16 is displayed on the LCD 12 by the CPU as shown in FIG. As a result, the input character A and the converted number 16 are displayed on the LCD. Also, this number is recorded in the memory 18.
