By mounting a microprocessor, it can be used as a general term for a terminal having a predetermined computing power.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, but the present invention is not limited or limited by the embodiments.

Figure 2 is a front view for explaining a personal portable terminal according to an embodiment of the present invention.

Referring to FIG. 2, the personal portable terminal 100 of the present invention includes a terminal body, a switch cam 125, a rotate wheel 150, a main sensor unit 140, and a sub sensor unit 140.

The terminal body may be provided in various ways according to the appearance or operation method, but in the present embodiment, the terminal body includes a main part 110 and a sliding part 120 that slides on the main part 110. It is provided with a slide-type personal portable terminal 100 to be opened and closed.

The main part 110 is selectively exposed by the movement of the slide part 120, and a keypad 112 for a user to input a number or a letter is formed. The slide part 120 checks the contents input by the user, and is provided with a display 123 for using functions such as multimedia and games provided by the personal mobile terminal 100, and the rotate wheel 150 is moved to the outside. Grooves are formed to partially expose them.

3 is a partial side cross-sectional view for explaining the operation of the rotary button in an embodiment of the present invention.

Referring to FIG. 3, the rotary button may include a switch cam 125 having a plurality of protrusions 126, a rotate wheel 150 rotating on the same axis 127 as the switch cam 125, and a lower portion of the rotate wheel 150. The protrusion 126 of the switch cam 125 is disposed adjacent to the main sensor unit 140 and the switch cam 125 to generate a wheel input signal in response to the vertical movement of the rotate wheel 150. The sub sensor unit 140 generates a cam input signal in response to the passing of the signal. In the present embodiment, six protrusions 126 are provided, but the number is not limited to the number according to the intention of the manufacturer.

The switch cam 125 is mounted inside the slide part 120 and a plurality of protrusions 126 are formed. At this time, the rotate wheel 150 is rotated on the same axis 127 as the switch cam 125.

The main sensor unit 140 is located below the rotate wheel 150, and generates a wheel input signal in response to the vertical movement of the rotate wheel 150. In detail, the main sensor unit 140 may rotate the rotate wheel. And a pressing bottom plate 132 formed below the pressing dome 131, and the pressing dome 131 and the pressing bottom plate 132 of the rotate wheel 150. The electrical signal can be generated by contact with the vertical flow.

Figure 4 is a partial side cross-sectional view for explaining the operation of the rotary button in one embodiment of the present invention.

Referring to FIG. 4, the sub sensor unit 140 is disposed adjacent to the switch cam 125, and generates a cam input signal in response to the passage of the protrusion 126 of the rotating switch cam 125. In detail, the sub sensor unit 140 is provided as a switch that is electrically connected to the passage of the protrusion 126.

Therefore, the personal portable terminal 100 according to the present invention generates the input signal by the main sensor unit 140 and the sub sensor unit 140 by the vertical movement of the rotate wheel 150 and the rotation of the switch cam 125, respectively. It is possible to simply generate an input signal.

In addition, in the conventional mobile phone, even without considering the area of the auxiliary keypad formed on the upper surface of the slide part, the personal portable terminal 100 of the present invention only needs to consider the area of the rotate wheel 150 protruding to the outside. 123 may be provided.

Of course, the auxiliary keypad can be used in the personal portable terminal adjacent to the display buoy as in the conventional mobile phone, and the position of the rotate wheel can be moved from the lower side of the display to the side of the display.

The personal portable terminal of the present invention can generate an input signal simply by generating an input signal by the vertical movement of the rotate wheel and the rotation of the switch cam, respectively.

In addition, without considering the area of the auxiliary keypad formed on the upper surface of the slide part in the conventional mobile phone, the personal handheld terminal of the present invention can provide a wider display because only the area of the rotator wheel protrudes to the outside.

In addition, a rotary button and a personal mobile terminal using the rotary button have an effect of providing various functions while occupying a small area.

As described above, although described with reference to the embodiments of the present invention, those skilled in the art will be able to variously modify and change the present invention without departing from the spirit and scope of the present invention described in the claims below. I can understand that it can.
