Abstract

PURPOSE:To input a character through only the depression of a key twice so as to reduce number of times of key depression considerably by depressing a function key so as to display while a numeral and a character or the like are arranged and entering a character or the like through the depression of a numeric key corresponding to the object character or the like. CONSTITUTION:A numeral is arranged and displayed on a display section 2 provided in a device main body 1 and a character or the like corresponding to the numeral is arranged and displayed and the character or the like is displayed accordingly by depressing a numeric key 3 displayed in this way. Thus, the numeral and the character or the like are displayed in the arranged state by depressing function keys A, A', C once and the entry of the character or the like is attained by depressing a numeral key 3 corresponding to the object character or the like and a desired character is entered with a few key depression.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a car telephone terminal device, and more particularly to a terminal device that allows input of characters and the like.

[Prior Art] Recent car telephone terminal devices have various service functions in addition to telephone calls. Some of these service functions require the input of alphabetic characters and symbols (hereinafter referred to as characters, etc.).

Generally, car phone terminal devices have numeric keys for inputting phone numbers etc. and function keys for executing various functions, but do not have keys for inputting characters etc. It's normal. For this reason, conventionally, terminal devices have been proposed in which characters and the like are input using numerical keys and function keys.

FIG. 4 is a front view of a conventional car phone terminal of this type, and FIG. 5 is a flowchart of a character input method in this terminal.

As shown in FIG. 4, this car phone terminal device is equipped with a display section 2 using a liquid crystal on the front of the device main body 1, numeric keys 3 from O to 1, and function keys A, B, and C. There is. Note that 4 is a speaker and 5 is a microphone.

A method for inputting characters and the like using this terminal device will be explained using the flowchart shown in FIG.

(1) First, by pressing the function key C for the character/number switching function, the character manual code is entered.

Then, the character that can be input is displayed on the display unit 2.

(2) If the displayed character is to be input, the character is input by pressing function key B.

(3) To input characters different from the displayed characters, press function key A. This will display the following characters: Thereafter, this operation is repeated until the target character is displayed, and when the target character is displayed, the operation (2) is performed to input the character.

(4) When inputting a predetermined character is completed or when exiting the character input mode, pressing function key C returns display unit 2 to its original state.

[Problem to be solved by the invention]

In the conventional terminal device described above, even if the only characters that can be input are A to Z, alpha to 7}, in the worst case,
For example, when inputting Z, function key A must be pressed 25 times before Z can be entered manually. In this case, add a function key A' and press this function key A, Z, Y.
Even if the display changes in the reverse order, it is necessary to press function key A or A' 14 times at maximum. Therefore, when inputting a plurality of characters, the number of key presses becomes extremely large, making the operation cumbersome.

SUMMARY OF THE INVENTION An object of the present invention is to provide a car telephone terminal device that allows desired characters to be input with a small number of key operations.

[Means for Solving the Problems] The mobile phone terminal device of the present invention is capable of displaying numbers in an array on a display section provided in the device body, and also allows displaying characters, etc. corresponding to these numbers in an array. , and by pressing the numeric key corresponding to the displayed number, the corresponding displayed character etc. can be input manually.

In this case, the display unit can be configured to display numbers 0 to 9 and characters corresponding to these numbers in two rows.

Further, it may be configured such that characters or the like corresponding to numbers are changed by pressing a function key.

[Function] According to the present invention, by pressing the function key once, numbers and letters, etc. are displayed in an array, and by pressing the numeric key of the number corresponding to the desired character, etc., the character, etc. is displayed. Enable input.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a front view of a car telephone terminal device of the present invention,
A display section 2 is provided on the front of the terminal device main body 1, and 0 to 9 are displayed here.
Numeric keys 3 and various function keys A, A', and C are provided. 4 is a speaker, and 5 is a microphone. Here, the function key C is configured as a function key for switching between a character input mode and a number input mode.

FIG. 2 is a flowchart showing a character input method in the terminal device of FIG. 1, and FIG. 3 is a display example of character input at that time. Here, the characters to be input in the character input mode are the alphabets from A to Z, a period ".", and a slash "/".

A character input method will be explained using FIGS. 2 and 3.

(1) First, press function key C to enter character mode. Then, as shown in FIG. 3(a), on the display section 2, the numbers 0 to 9 and the corresponding letters A to J are displayed in two rows in a state that they correspond to each other.

(2) If the character to be input exists in A-J, press the number key corresponding to the character. This causes the character to be input. For example, in this state, pressing "0" will input "A", and pressing "8" will input "■".

(3) If the desired character is not found among the displayed characters, press function key A. Then, the characters corresponding to the numbers 0 to 9 are changed to K-T as shown in FIG. 3(b). If the desired character exists among these characters, the user inputs the character by performing the same operation as in (2) above. For example, if you press "0" in this state, "K" will be input, and "8" will be input.
When you press , "S" is input.

If the desired character does not exist, press function key A again.
Press.

(4) When function key A is pressed again, the characters corresponding to the numbers 0 to 9 are changed as shown in FIG. 3(C).

Then, by pressing the number key corresponding to the desired character, the character can be input.

Note that if you do not want to input characters or want to return to the original mode from the character mode, you can press the function key C.Also, by pressing the function key A', the display on the display section 2 can be changed to From state a) to Figure 3(C) and Figure 3(b)
It is possible to change the display in the opposite direction to the display of , and it is possible to reduce the number of times the function keys A and A' are pressed to display the desired character.

Therefore, with this terminal device, by simply selecting and pressing the function key A or A' once, the desired character is displayed.
In addition, the input can be made by pressing the corresponding numeric key once. Furthermore, even if only the function key A or A' is pressed, the desired character can be displayed with a maximum of two operations.

This makes it possible to reduce the number of key operations when inputting characters, and to significantly improve the operability of the terminal device.

〔Effect of the invention〕

As explained above, in the present invention, by pressing a function key,
By displaying numbers and letters in an array, and pressing the numeric key that corresponds to the desired letter, you can enter the desired letter, etc., by simply pressing the key twice. This has the effect of greatly reducing the number of key operations.
