Some conventional portable communication terminals of this type display character information (messages) received from the other party on a display.
[0003]
[Problems to be solved by the invention]
However, as the amount of information increases, the message extends over a plurality of pages, so that an operation for updating the screen is necessary to read all the received character information.
[0004]
Therefore, a main object of the present invention is to provide a portable communication terminal capable of displaying received character information with a small number of pages.
[0005]
[Means for Solving the Problems]
Portable communication terminal according to the present invention, receiving means for receiving the character code, display means for displaying based rather text to the character code received by the receiving means, first receiving means receives the font switching operation, and the display means Is provided with a font switching means for switching only the kana characters of kanji and kana characters forming the sentence displayed between the full-width and half-width in response to the character switching operation, and the full- width kana includes at least hiragana, The character switching operation includes a first kana switching operation and a second kana switching operation, and the font switching means switches full-width kana to half-width kana in response to the first kana switching operation. In response to the second kana switching operation, the half-width kana is switched to the full-width kana .
[0006]
[Action]
The character code is received by the receiving means. The text based on the character code received by the receiving means is displayed by the display means. The font switching operation is received by the first receiving means. The font switching means switches only the kana characters of the kanji and kana characters forming the sentence displayed by the display means between full-width and half-width in response to the font switching operation.
[0007]
Here, a full-width kana includes at least hiragana, and a half-width kana is a half-kana. The font switching operation includes a first kana switching operation and a second kana switching operation. The font switching means switches the full-width kana to half-width kana in response to the first kana switching operation, and switches the half-width kana to full-width kana in response to the second kana switching operation.
[0008]
In one aspect of the present invention, character data representing a plurality of fonts is stored in a memory. Font switching means, to read out the character data corresponding to the character code and express a desired font from the memory.
[0009]
In another aspect of the present invention , when a line interval switching operation is accepted, the line interval switching unit switches the line interval of the text displayed by the display unit .
[0010]
【The invention's effect】
According to the present invention, since the kana character font included in the kana-kana mixed character is switched, the received character information can be displayed on the display with a small number of pages.
[0011]
The above object, other objects, features and advantages of the present invention will become more apparent from the following detailed description of embodiments with reference to the drawings.
[0012]
【Example】
Referring to FIG. 1, a mobile phone 10 of this embodiment includes an antenna 12. The antenna 12 receives the message code of the other party transmitted from the base station. The received message code is given to the CPU 16 via the transmission / reception circuit 14 and written into the RAM 18 by the CPU 16. When the operator performs a predetermined key operation, this message code display process is performed. That is, the ROM 24 stores full-width (12 × 12 dots) Kanji, hiragana, and half-width (12 × 6 dots) half-width character data. The CPU 16 reads out character data corresponding to the message code from the ROM 24 and gives it to the LCD driver 20. The LCD driver 20 drives the LCD 22 according to the input character data, and as a result, a received message corresponding to the message code is displayed on the screen. Note that the screen of the LCD 22 has a size capable of displaying 24 full-width characters of 12 × 12 dots.
[0013]
When the operator inputs a message and the other party's telephone number, the CPU 16 temporarily writes the input message code in the RAM 18 and then transmits the other party via the transmission / reception circuit 14 and the antenna 12. Such message code transmission / reception is based on, for example, the P-mail DX service provided by DDI Pocket Telephone Co., Ltd., and satisfies the so-called P-mail protocol.
[0014]
The processing of the CPU 16 when displaying the message code written in the RAM 18 on the LCD 22 will be described with reference to FIG. The message corresponding to the received message code is as shown in FIG.
[0015]
The CPU 16 first determines whether or not the message display key 22 has been pressed in step S1. If YES is determined here, the CPU 16 proceeds to step S3, and displays the received message on the LCD 22 in the standard mode. That is, full-width kanji, full-width hiragana and full-width kana character data corresponding to the message code held in the RAM 18 is read from the ROM 24 and supplied to the LCD driver 20. As a result, as shown in FIG. 4A, a message for 24 characters from the top is displayed on the LCD 22.
[0016]
Subsequently, the CPU 16 determines whether or not the update key 32 has been pressed in step S5, and determines whether or not the display mode switching key 30 has been pressed in step S7. If “YES” in the step S5, the page displayed on the LCD 22 is updated. For this reason, when the update key 32 is pressed while the message shown in FIG. 4A is displayed, a message for 24 characters following the message is displayed on the LCD 22. On the other hand, if “YES” in the step S7, the current display mode is determined in each of the steps S11, S15, and S19.
[0017]
If the current display mode is the standard mode, the CPU 16 proceeds from step S11 to step S13, and displays a message on the LCD 22 in mode a. Mode a is a mode for displaying a message using full-width kanji and half-width kana. For this reason, in step S13, the same character data is read from the ROM 24 for characters displayed in full-width kanji in the standard mode. On the other hand, for the characters displayed in full-width hiragana and half-kana in the standard mode, character data in half-width half-kana is read out. That is, the message code indicating the full-width hiragana and the half-kana is converted into the message code indicating the half-width kana, and the character data corresponding to the converted message code is read from the ROM 24. As a result, a message is displayed on the LCD 22 in the manner shown in FIG. As a result of replacing full-width hiragana and half-kana with half-width half-kana, more characters can be displayed on the screen than in the standard mode. When the display process is completed, the process returns to step S5.
[0018]
If the current display mode is mode a, the CPU 16 determines YES in step S15, and proceeds to step S17. In this step, a message corresponding to the message code held in the RAM 18 is displayed on the LCD 22 in mode b. Mode b is a mode in which the character spacing in the vertical direction, that is, the line spacing, is set to 2/3 of the standard mode, and a message is displayed using full-width kanji and full-width kana. Therefore, as shown in FIG. 4C, a message for four lines, that is, 32 characters is displayed on the LCD 22. When such display processing is completed, the CPU 16 returns to step S5.
[0019]
If the display mode switching key 30 is pressed when the current display mode is mode b, the CPU 16 proceeds from step S19 to step S21. In step S21, the message is displayed on LCD 22 in mode c. Mode c is a mode in which the character spacing, that is, the line spacing in the vertical direction is set to 2/3 of the standard mode, and a message is displayed using full-width kanji and half-width kana. Therefore, the message is displayed on the LCD 22 in the manner shown in FIG. When the display process is completed, the CPU 16 returns to step S5.
[0020]
If the display mode key 30 is pressed when the current display mode is mode c, the CPU 16 proceeds from step S19 to step S23. Then, the message is displayed on the LCD 22 in the standard mode. That is, character data corresponding to the message code stored in the RAM 18 is read from the ROM 24 and output to the LCD driver 20. For this reason, the display form of the message is changed from FIG. 4D to FIG.
[0021]
According to this embodiment, the font of the message displayed on the LCD is changed in the order of standard mode → mode a → mode b → mode c → standard mode in response to the operation of the display mode switching key. Specifically, the kana character font and / or line spacing is switched. Therefore, the received message can be displayed on the LCD screen with a small number of pages.
[0022]
In this embodiment, the case where the received message is displayed on the LCD has been described. However, the present invention can also be applied to the case where a message (message being created) to be transmitted to the other party is displayed on the LCD.
