For example, the composite key module 130g may adjust the volume of audio data output from the sound output module 153 when the slide is performed.

When the composite key module 130g is pushed, different key input data may be generated according to the slide position. The controller 180 may recognize different key input data by combining the electrical signal generated by the proximity sensor 141 and the electrical signal generated when the compound key module 130g is pushed in the slide position. That is, according to the position where the compound key module 130g is slid, the user may push the compound key module 130g to input different commands or information. For example, if the composite key module 130g is pushed when the composite key module 130g is in the A position, the mobile terminal 100 may be turned on / off, and the composite key module 130g is in the A 'position. When this is pushed, the lighting of the display unit 151 may be turned on / off.

It may be configured.

On the other hand, the present invention can be implemented as a processor-readable code in a processor-readable recording medium provided in the mobile terminal, such as MSM (Mobile Station Modem). The processor-readable recording medium includes all kinds of recording devices that store data that can be read by the processor. Examples of the processor-readable recording medium include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage device, and the like, and also include a carrier wave such as transmission through the Internet. The processor-readable recording medium can also be distributed over network coupled computer systems so that the processor-readable code is stored and executed in a distributed fashion.

In addition, while the above has been shown and described with respect to preferred embodiments of the present invention, the present invention is not limited to the specific embodiments described above, the technology to which the invention belongs without departing from the spirit of the invention claimed in the claims Various modifications can be made by those skilled in the art, and these modifications should not be individually understood from the technical spirit or the prospect of the present invention.
