The position display unit can be implemented in a form that the user can recognize through a tactile sense or a visual sense.
For example, as shown in Fig. 4, the position display portion may be embodied as at least two grooves 132g-1 and 132g-2 formed on the outer peripheral surface of the cover 131g.
As another example, although not shown in the drawings, the position indicator may be implemented with at least two protrusions formed on the outer circumferential surface of the cover 131g.

There is a problem that all the functions desired by the user can not be activated merely by generating the key input data by touching the display unit 151 while the use form of the mobile terminal is diversified. For example, when playing a game through a mobile terminal, the game is played in full screen. The game screen is activated while the game is being played so that a function (e.g., status bar, memo, translation, capture, etc.) that can be activated by touching the display unit 151 can not be used.
By using the user input section 135g using the touch sensor modules 133g and 137g on the side of the case, key input data inputted from the case side can be variously generated. In addition, when playing a game or the like using the mobile terminal, the game screen is activated, and a function (e.g., status bar, memo, translation, capture, etc.) that can not be activated by touching the display unit 151 .
By using the user input section 135g using the touch sensor modules 133g and 137g on the side of the case, key input data inputted from the case side can be variously generated.
For example, when the user touches an area near the first groove 132g-1, the touch sensor 133g receives the signal and outputs a first signal to the control unit 180, The touch sensor 133g receives the signal and outputs a second signal to the control unit 180 so that the second key input data 132g- The touch sensor 133g receives the signal and outputs a third signal to the controller 180. The touch sensor 133g outputs a third signal to the touch sensor 133g, The touch sensor 133g receives the signal and outputs the key input data to the control unit 180. When the user touches the area near the first groove 132g-1 and the second groove 132g-2 simultaneously, To generate a fourth key input data, and the user touches an area near the first groove 132g-1 and, within a predetermined time, When the touch area of the near (132g-2), a touch sensor (133g) is capable of outputting a fifth signal to the controller 180 receives the signal, generating a fifth keystroke data. However, the present invention is not limited to this, and various key input data can be generated.
Further, the area where the user can generate the key input data can be easily recognized by the position display unit formed on the outer peripheral surface of the cover 131g.
In addition, since the outer circumferential surface of the cover 131g is formed integrally with the outer circumferential surface of the case, the assembly line of the mobile terminal disappears, thereby improving the aesthetics.
FIG. 5 is a rear view illustrating a rear surface of a mobile terminal according to an embodiment of the present invention, and FIG. 6 is a rear view illustrating a rear surface of the mobile terminal according to another embodiment of the present invention .
The controller 180 of the mobile terminal, the board 137g, and the main board 20 may be connected by various methods.
5, the user input unit 135g is connected to the control unit 180 through the board 137g, the control unit 180 is disposed on the board 137g, and the main board 20 May be connected to the control unit 180 by a connector 21. [
6, the control unit 180 is disposed on the main board 20, and the board 137g of the user input unit 135g may be connected by the control unit 180 and the connector 139g .
7 and 8 are views for explaining the operation of the mobile terminal according to an embodiment of the present invention.
The mobile terminal of the embodiment may further include a control unit 180 for activating a preset function based on the key input data generated by the user input unit 135g.
The predetermined function activated by the control unit 180 may include any one of volume control, vibration / sound mode conversion, memo, capture and translation functions. However, the present invention is not limited thereto, and various functions may be activated.
In particular, the control unit 180 may activate the memo function when the drag input signal is input to the user input unit 135g. Here, the drag touch input means a case where the user touches the area near the first groove 132g-1 and touches the area near the second groove 132g-2 within a predetermined time or vice versa something to do.
Hereinafter, various operations using the embodiment will be described with reference to the drawings.
7A, when the user touches the area near the first groove 132g-1 for a predetermined time or less, the touch sensor 133g receives the signal and outputs the first signal to the controller 180 And generates the first key input data. The controller 180 receiving the first key input data outputs a control signal for increasing the volume.
When the user touches the area near the second groove 132g-2 for a predetermined time or less, the touch sensor 133g receives the signal and outputs a second signal to the controller 180, . The controller 180 receiving the second key input data outputs a control signal for reducing the volume.
7B, when the user touches the area near the first groove 132g-1 or the second groove 132g-2 for more than a predetermined time, the touch sensor 133g receives the signal, And outputs a third signal to the second key input unit 180 to generate third key input data. The controller 180 receiving the third key input data outputs a control signal for switching to the vibration / sound mode.
7C, when the user touches the area near the first groove 132g-1 and the second groove 132g-2 at the same time, the touch sensor 133g receives the signal and sends the signal to the controller 180 And outputs a fourth signal to generate fourth key input data. Upon receiving the fourth key input data, the controller 180 outputs a control signal for switching to the power saving / normal mode.
8A, when a user drags (slides) from the first groove 132g-1 to the second groove 132g-2 (within a predetermined time after the first groove 132g-1 is touched, the second groove 132g- 2), the touch sensor 133g receives the signal and outputs a fifth signal to the controller 180 to generate the fifth key input data. The controller 180 receiving the fifth key input data outputs a control signal for activating the memo function. Here, the memo function may include a function of simultaneously memorizing the screen while capturing the screen.
Referring to FIG. 8B, when the user drags (slides) from the second groove 132g-2 to the first groove 132g-1 (within a predetermined time after touching the second groove 132g-2) 1), the touch sensor 133g receives the signal and outputs a sixth signal to the controller 180 to generate the sixth key input data. The controller 180 receiving the sixth key input data outputs a control signal for activating the quick voice function. Here, the Quick Voice function records and saves the voice.
8C, when the user drags (slides) from the first groove 132g-1 to the second groove 132g-2 and moves from the second groove 132g-2 to the first groove 132g-1 In the case of a drag (sliding) touch, the touch sensor 133g receives the signal and outputs a seventh signal to the control unit 180 to generate the seventh key input data. The control unit 180 receiving the seventh key input data outputs a control signal for activating the translation function.
As described above, the mobile terminal using the user input unit 135g of the embodiment can generate a hot key that performs various functions with a simple structure.
While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, It should be understood that various modifications may be made by those skilled in the art without departing from the spirit and scope of the present invention.
