Abstract

PROBLEM TO BE SOLVED: To prevent displayed characters from being erroneously deleted and to improve convenience by preventing a deletion processing from being directly executed, even if the operation of the deletion of the displayed character is executed, once confirming the operation of deletion and executing the processing of deletion when there is the input of the confirmation key of the deletion operation. SOLUTION: When the operation of deletion is executed, 'can this be deleted? Yes:1 No:2' is displayed as the confirmation message, for example. Then, data is displayed on a display part 2, an operation part 1 is monitored, and it is judged whether either key '1' or '2' has been depressed. When '1' has been depressed as the key showing 'Yes', for example, the processing of deletion for deleting the inputted characters displayed on the display part is executed, and the display of the display part 2 is deleted. Thus, data is deleted after the confirmation of deletion, even if the operation of the deletion of the characters which are erroneously displayed has been executed. Thus, display is prevented from being erroneously deleted, and convenience is enhanced.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable telephone including a PHS, a car telephone and the like, and more particularly to a portable telephone which can prevent adverse effects caused by an incorrect operation and has high convenience.

[0002]

2. Description of the Related Art FIGS. 3 and 4 show a conventional portable telephone.
This will be described with reference to FIG. FIG. 3 is an explanatory diagram showing an outline of the appearance of a conventional mobile phone, and FIG. 4 is an explanatory diagram showing display contents on a display unit 2 of the conventional mobile phone. As shown in FIG. 3, a conventional mobile phone mainly includes an operation unit 1,
And a display unit 2.

Here, when the user operates the operation unit 1 and inputs a telephone number “123-4567”, the display unit 2 displays the number as shown in FIG. become. Then, when the user operates the operation unit 1 and goes off-hook, the telephone number is called.

[0004] Further, the user enters the telephone number "123-45".
If "67" is erroneously input, for example, by operating a clear key or an on-hook key of the operation unit 1 or performing an erasing operation, erasing is performed from the last input number. 4A, if the clear key is pressed once, as shown in FIG.
456 ", and the display changes.

Further, it has been considered that input numbers are collectively erased in response to operation of a clear key or an on-hook key.

[0006]

However, in the above-mentioned conventional portable telephone, when an erasing operation is performed by mistake on displayed characters or the like, the erasing process is immediately performed, and the erasing process is performed. There was a problem that convenience was low because it could not be canceled.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a portable telephone capable of confirming an erasing operation to thereby prevent adverse effects caused by an erroneous erasing operation.

[0008]

According to a first aspect of the present invention, there is provided a portable telephone, comprising: a display unit for deleting a displayed character, numeral, symbol, or the like; A message for confirming the operation is displayed, and it is determined whether or not a key for confirming the erasing operation has been input. When the key for confirming the erasing operation is entered, the erasing process is performed. Therefore, it is possible to prevent the displayed characters and the like from being erased by mistake, and to enhance the convenience.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A portable telephone according to an embodiment of the present invention will be described with reference to the drawings. In the mobile phone (this device) according to the embodiment of the present invention, when there is an erasing operation, the mobile phone (the present device) performs a check once before actually performing the erasing process, and can prevent the adverse effects caused by an erroneous erasing operation. , Convenience can be improved.

The present apparatus is the same in appearance as a conventional portable telephone, but the operation when an erasing operation is performed is slightly different.

That is, the present apparatus performs the processing as shown in FIG. FIG. 1 is a flowchart showing the processing operation of the present apparatus. As shown in FIG. 2A, the numbers input through the operation unit 1 are displayed on the display unit 2 as in the conventional case.
Will be displayed. FIG. 2 is an explanatory diagram showing display contents of the apparatus.

Here, when the erasing operation is performed, the processing shown in FIG. 1 is started, and, for example, "Erase or not: High: 1 No: 2" is displayed on the display unit 2 as a confirmation message (S1). . Then, a display as shown in FIG. 2B is made on the display unit 2. Then, the apparatus monitors the operation unit 1 and determines which key of “1” or “2” has been pressed (S2).

Here, for example, if "1" is pressed as a key indicating "high" (if it is "1"), input characters and the like displayed on the display unit 2 are deleted.
An erasing process is performed (S3), and the display on the display unit 2 is the
Erase is performed as shown in FIG.

In step S2, if "2" is pressed as a key indicating "no"("2"), the initial display contents are displayed (S4). And
The display content of the display unit 2 remains unchanged as shown in FIG.

In addition, in the environment where the user does not look, the processing S
In 2, if neither key is pressed for a certain period of time,
It is also conceivable to end the processing.

According to the present invention, even if an erroneously displayed character or the like is erased, the erasure is performed by confirming the erasure, so that the erroneous display is prevented. This has the effect of preventing and improving convenience.

[0017]

According to the first aspect of the present invention, even if an operation of erasing a displayed character or the like is performed, the erasing operation is not performed immediately, the erasing operation is confirmed once, and the confirmation key of the erasing operation is pressed. Since it is a mobile phone that performs erasure processing when there is an input, it prevents the displayed characters etc. from being accidentally erased,
There is an effect that convenience can be improved.
