The audio converter 130 converts the voice data received from the wireless circuit unit 120 into an audible sound through the speaker SPK and modulates the voice signal received from the microphone MIC under the control of the controller 100. It converts the voice data and transmits it to the controller 100.

The key input unit 140 includes a plurality of dial keys and function keys, and generates a corresponding key signal when the user presses a predetermined key and outputs the corresponding key signal to the controller 100.

The display unit 150 may be formed of a display device such as a liquid crystal display (LCD), an organic light emitting diode (OLED), or the like, and is selected by a user of the mobile communication terminal under the control of the controller 100. The menu screen, the execution screen, and the result screen are displayed. In particular, the present invention shades a plurality of files selected by the file selection key. A screen example showing this is shown in FIG. 3. This will be described later.

When the function key set as the combination selection key is input in a menu window providing a list of files stored in the mobile communication terminal, the key combination module unit 160 stores the combination selection voltage and inputs the next key while the combination selection voltage is stored. When the analog-to-digital converter (ADC) recognizes the potential, it sets the next key to the file selection key.

2 is a front view of a mobile communication terminal capable of selecting a plurality of files according to an embodiment of the present invention.

As shown in FIG. 2, a display unit 150 is provided in an upper folder of a foldable mobile communication terminal, and a key input unit 140 for generating a key signal is provided in a lower folder. The key input unit 140 includes a combination selection key 142 for outputting a combination selection key signal according to a user input from a list in which a plurality of files are stored, and a file selection for selecting a plurality of files while a combination selection signal is input and stored. Keys 144 and 144 'are provided. Here, the file selection keys 144 and 144 'may include a direction key 144 for collectively selecting a plurality of files, and a file for selectively selecting the files in the order in which the plurality of files are displayed on the display unit 150. Consisting of a dial key 144 '. In this way, the plurality of selected files are simultaneously performed by the corresponding key 146 signal input next.

3 is a diagram schematically illustrating a key combination circuit of a mobile communication terminal capable of selecting a plurality of files according to an embodiment of the present invention, wherein a plurality of files are selected according to the combination of the combination selection key signal and the file selection key signal described above. The process will be described with reference to FIG. 3 as follows.

When the combination selection key is selected from a list in which a plurality of files are stored and a combination selection signal is input to the analog / digital converter (ADC) 162, the key combination module 160 included in the mobile communication terminal selects the storage capacitor Cp. Stores the input combination selection voltage. Thereafter, in the state where the combination selection voltage is stored in the storage capacitor, a key input to the GPIO (General Purpose Input / Output Pin) 161 is set as a file selection key before the voltage is discharged, and the file is simultaneously selected by the input signal.

A key input method of the mobile communication terminal having such a configuration will be described with reference to FIG. 4 as follows.

As shown in FIG. 4, in the key input method of the present invention, a key signal is input from a list in which a file is stored. Determining whether the input key signal is a combination selection key signal; and if the input key signal is a combination selection key, the analog / digital converter (ADC) recognizes the potential of the combination selection key and selects the next input key. And setting a plurality of files simultaneously in accordance with a key signal input by the file selection key.

Referring to the operation of the present invention configured in this way in more detail as follows.

In the key input method according to the present invention, when a key signal is input in a menu window S100 providing a list of files stored in the mobile communication terminal (S110), the control unit 100 recognizes the input key signal (S120). Check whether the combination selection key signal (S130). Thereafter, when the input key signal coincides with the key data set as the combination selection key, the key combination module 160 recognizes the analog / digital converter (ADC) potential and sets the next input key as the file selection key (S140).

On the other hand, if the key signal input from the file list menu window is not the key signal set as the combination selection key, the corresponding function of the input key is performed (S160).

Here, the combination selection key may be any one of a plurality of function keys, and the file selection key may collectively select a plurality of files and a dial key for individually selecting files listed in order in the file list window. It is preferable that the direction key being present.

Thereafter, the plurality of files are simultaneously selected according to the key signal input by the file selection key (S150), and the selected plurality of files are deleted or transmitted at once.

A screen example showing a plurality of files selected by the key combination and performing the same function on the selected files is shown in FIG. 3.

Referring to step (a) of FIG. 3, a function key set as a combination selection key is input in a menu window providing a list of picture files stored in a mobile communication terminal. At this time, when the combination selection key 142 is pressed and the combination selection voltage is input, the key combination module 160 stores the combination selection voltage in the capacitor Cp. One side of the capacitor Cp is connected to the combination selection key 142 and the analog / digital converter ADC 162, and the other side of the capacitor Cp is grounded to store the combination selection voltage input through the resistor R. Subsequently, referring to step (b), a file is stored in the GPIO (General Purpose Input / Output Pin) 161 before the stored voltage is discharged while the combination selection key 142 signal is stored in the capacitor Cp. When a selection key signal is input, two or more files are simultaneously selected by the input signal. Thereafter, the delete menu key is input to the selected plurality of files as in step (c). Then, as in step (d), a plurality of files are deleted at once.

Therefore, it is efficient to reduce the hassle of selecting a file and performing a corresponding function by pressing a key button.
