Abstract

PROBLEM TO BE SOLVED: To easily recognize the disability of new character input for a user by changing the shape of a cursor when the number of characters inputted by the user reaches the maximum acceptable number of characters. SOLUTION: At the time of an input mode for accepting an input such as a character input from the user at a portable telephone set, a control circuit judges whether or not the number of characters inputted by the user reaches the maximum acceptable number of characters allocated to each item of an input buffer memory. While the buffer memory has an allowance in the number of characters to be inputted, a cursor K1 in the shape of a frame only is displayed on the screen of an LCD device but when the number of inputted characters reaches the maximum inputtable number of characters, a cursor K2 in the shape painted out for one picture element is displayed on the LCD device. Thus, the user can easily recognize that no more input is accepted only by watching the shape of the cursor and since the cursor is displayed at all times, even when work is temporarily stopped, input disability is comprehended so that the unwanted input operation can be prevented.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication terminal device and can be applied to, for example, a mobile phone.

[0003]

2. Description of the Related Art Today, many mobile phones have a function of storing a telephone number and various management information. By the way, the number of input characters that a mobile phone can accept is usually limited when these various functions operate, and the number of characters is determined for each item. For example, the password is 8 characters, the telephone number is 64 characters, and the name registered in the telephone book is 16 characters.

[0004]

In the case of the conventional mobile phone, when the user's input fills the input buffer memory and further user's input is made, a warning sound is emitted or an LCD or the like is blinked. Therefore, it is general to notify the user that no further input will be accepted.

However, in these methods, the system does not notify the user that the input buffer memory is full unless the maximum number of characters that can be input is input. I didn't know if more input would be accepted. Further, since the warning sound and the blinking of the LCD are usually instantaneous operations, it may not be possible to know whether or not the input can still be made if the input work is interrupted.

The present invention has been made in consideration of the above points, and is intended to propose a communication terminal device that allows a user to easily recognize whether or not an input to an input buffer memory is possible. is there.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail with reference to the drawings.

FIG. 1 shows a mobile phone 1 as an example of a communication terminal device according to the present invention. The mobile phone 1 is mainly composed of a control circuit 2. The control circuit 2 has a microprocessor configuration and controls internal circuits such as the modulation / demodulation circuit 3 and the voice coding / decoding circuit 4.

At the time of reception, the modulation / demodulation circuit 3 inputs the signal of the radio frequency band received by the antenna through the switch SW, and the demodulated signal is the voice encoding / decoding circuit 4.
Works to output to. At this time, the audio encoding / decoding circuit 4 decodes the demodulated signal into an audio signal and outputs it to the speaker 6 via the amplifier 5.

At the time of transmission, the voice encoding / decoding circuit 4 operates so as to encode the voice signal input via the microphone 7 and the amplifier 8 and output it to the modulation / demodulation circuit 3. At this time, the modulation / demodulation circuit 3 modulates the input voice signal into a signal in the radio frequency band and transmits the signal via the switch SW and the antenna.

The mobile phone 1 is capable of preliminarily registering the other party's telephone number and name as well as various functions. At this time, the input means 9 and the memory 10 which are numeric keys and the like are used. The control circuit 2 is the memory 10
A call is made based on the data registered in, and the content is displayed on the display screen of the LCD device 11. The LCD device 11 is driven by the LCD drive circuit 12.

Further, in the user input mode in which the control circuit 2 shown in this embodiment receives an input such as a character input from the user, whether or not the number of characters input by the user has reached the maximum allowable number of characters assigned to each item. The shape of the displayed cursor is changed when the maximum number of characters is reached.

2 and 3 show examples of cursor display in the password input mode. However, in the case of this embodiment, the maximum number of characters that can be accepted in the password input mode is 8 characters. Here, FIG. 2 is an example when the number of input characters has not reached the maximum number of characters that can be input, and FIG. 3 is an example when the number of input characters has reached the maximum number of characters that can be input.

That is, the portable telephone 1 displays the cursor K1 in the shape of a frame only on the screen of the LCD device 11 while the number of characters that can be input is large as in the case of FIG. As described above, when the number of characters already input reaches the maximum number of characters that can be input, the cursor K2 shaped to fill one pixel is displayed on the LCD device 11.

Next, FIG. 4 shows a determination procedure used by the control circuit 2 to realize this function. First, when the user input mode is designated, the control circuit 2 starts the processing from step SP1 and determines whether or not the user has input a character at step SP2. When a negative result is obtained in step SP2, the control circuit 2 moves to step SP3 to determine whether or not an input confirmation is instructed, and returns to step SP2 until a positive result is obtained and prepares for input from the user.

Incidentally, when a positive result is obtained in step SP3, the control circuit 2 determines the characters input so far, and then moves to step SP4 to end the user input mode. If a positive result is obtained in step SP2, the control circuit 2 proceeds to step S
The process proceeds to P5, and it is determined whether confirmation of the input character is instructed. If a positive result is obtained in step SP5 and it is found that the confirmation instruction has been input, the control circuit 2 proceeds to step SP4 and terminates the user input mode, as in the determination result in step SP3.

On the other hand, when a negative result is obtained in step SP5, the control circuit 2 moves to step SP5 and determines whether or not the input buffer is full by the current input. If a negative result is obtained in step SP6, that is, if the input buffer has a margin, the control circuit 2 moves to step SP7 to instruct to input the character input by the user into the input buffer memory. On the other hand, if a positive result is obtained in step SP6, the input buffer is already full at this input, so the control circuit 2 moves to step SP8 and it is determined that the input buffer is full. It is determined whether is the first time.

If a positive result is obtained at step SP8, the control circuit 2 proceeds to step SP9 to fetch the current input into the input buffer memory and gives an instruction to change the shape of the cursor. That is, the cursor displayed on the screen is changed from the cursor K1 to the cursor K2.
Instruct to switch to. On the other hand, if a negative result is obtained in step SP8, step SP
Move to 10 and reject the input.

When the processing of any one of these steps SP7, SP9 or SP10 is completed, the control circuit 2 shifts to the processing of step SP11 and displays the information according to each processing result on the screen. For example, when moving from step SP7 to step SP11,
The control circuit 2 issues an instruction to cause the LCD device 11 to display a cursor K1 indicating a ready-to-input state together with the series of input characters.

Also, from step SP9 to step SP11
Control circuit 2 issues an instruction to display a cursor K2 indicating that the input buffer memory is already full and no further characters can be input together with the input series of characters. Further, when the process moves from step SP10 to step SP11, the control circuit 2 rejects the input of the character, and the cursor K2 indicating that the input buffer memory is full and the character cannot be input any more together with the already input character. Instruct to display. After the processing of step SP11 is completed, the control circuit 2 returns to step SP2 and repeats the above-mentioned processing.

An example of the operation of the mobile phone 1 in the password input mode having the above configuration will be described. For example, when the number of characters input by the user is up to 7, the control circuit 2 controls the steps SP2 to SP5 to SP6.
-Step SP7-Step SP11-Step SP2
The processing routine is repeated to display the input character and the cursor K1. If the user gives an instruction to confirm the input characters, step SP2 or step SP5
To step SP4, the process is exited.

When the number of input characters reaches eight, the control circuit 2 passes through the processing route from the above-mentioned processing routine through step SP2-step SP5-step SP6-step SP8-step SP9-step SP11.
Accepts the input of the 8th character, displays it on the screen, and changes the cursor to the previous cursor K1 and changes the cursor to K2.
Change to

The display of the cursor K2 shows that the user cannot accept any more input. Moreover, since the cursor is always displayed, it is possible to understand at any time that the input cannot be made even if the work is suspended after the input is not accepted. If a character is erroneously input in this state, the control circuit 2 causes the steps SP2 to SP5 to SP6.
-Step SP8-Step SP10-Step SP1
As a result, the process route 1 is entered, and input of new characters is rejected.

According to the above configuration, the shape of the cursor displayed on the display screen is changed based on whether or not the number of input characters has reached the maximum number of characters that can be received. By simply looking at the shape, it is possible to confirm whether or not a new character input instruction can be given by key operation and accepted, and unnecessary operation is avoided.
Also, since the cursor is always displayed, it is possible to confirm whether or not the input of characters can be accepted at any time, not only at the moment when the number of input characters reaches the maximum number of characters.

In the above embodiment, the case of inputting a password has been described, but the present invention is not limited to this, and may be applied to the case of inputting a telephone number or registering a name in a telephone directory. . Incidentally, the maximum number of characters that can be input in each of these input modes can be set to an arbitrary value.

Further, in the above embodiment, the cursor K displayed when the number of input characters does not reach the maximum number of characters
Regarding the case where the shape of 1 is a frame shape as shown in FIG. 2 and the shape of the cursor K2 displayed when the number of input characters reaches the maximum number of characters is one pixel filled as shown in FIG. Although described, the present invention is not limited to this, and the shape of the cursor can be applied to other cases.

Further, in the above-mentioned embodiment, the case has been described in which whether or not the number of input characters has reached the maximum number of characters is indicated only by changing the display of the cursor, but the present invention is not limited to this, and the display of the cursor is switched. At the same time, a warning sound may be generated or the display of the LCD device 11 may be blinked while the cursor display is switched to notify the state of the input buffer memory.

Further, in the above-mentioned embodiment, the portable telephone has been described as an example of the communication terminal device, but the present invention is not limited to this, and other wireless communication terminal devices also include wired communication terminal devices. It can also be applied in some cases. Incidentally, as a wireless communication terminal device, there is a portable information terminal or the like which mainly sends and receives text data. Further, as a wired communication terminal device, there is a wired telephone or the like.

Furthermore, in the above-mentioned embodiments, the LCD device is described as the display means, but the present invention is not limited to this, and other display means may be used.

[0031]

As described above, according to the present invention, when the number of characters input by the user reaches the maximum number of characters that can be accepted, the shape of the cursor is changed from the first shape to the second shape. As a result, the user can obtain the communication terminal device that can confirm whether or not a character can be newly input only by confirming the shape of the cursor displayed on the display means.
