The side key module 300, the side button 310 is provided on one side of the main body 100; A pressure sensing sensor member 320 provided on one side (that is, an inner side surface) of the side button 310 and transmitting a signal signal to the printed circuit board 200 when the side button is operated; A dome member 330 provided between the pressure sensing sensor member 320 and the side button 310 to give a click feeling when the side button is operated; And a connector 340 provided at one side of the printed circuit board 200 to be connected to the pressure sensing sensor member 320 so that the signal signal of the pressure sensing sensor member 320 is transmitted to the printed circuit board 200. Include.

Here, the receiving unit 110 is formed on one side of the main body so that the pressure sensor member 320 and the side button 310 is provided.

The side button 310 is a member directly acting to the user to scroll and click the content embedded in the main body 100 or to adjust the volume, and at the same time serves to deliver the pressure (force) to the pressure sensor member 320. Do it.

In addition, the pressure sensing sensor member 320 is a sensor having a pattern (pattern) through which electricity can flow therein, which detects a position by changing a resistance value according to the degree of external pressure. Here, the minimum operating force of the pressure sensor member 320 is approximately 20gf, the thickness is preferably about 0.3 ~ 0.5mm.

In addition, the dome member 330 is an elastic member which causes ON / OFF operation by an appropriate force (about 150 to 200 gf). In this embodiment, the dome member 330 is used to give a click feeling without direct switching. Use only as a means.

Hereinafter, the configuration and operation of each component described above will be described in more detail.

3 and 4, the front surface of the side button 310, the scroll unit 311 is formed in a flat form on one side to scroll the content embedded in the main body 100; And at least one click part 312 formed on the other side to protrude from the scroll part 311 to be clickable on the content.

The rear surface of the side button 310, a plurality of scroll actuators 313 formed on one side in order to transfer the operation of the scroll unit 311 to the pressure sensor member 320; A click actuator 314 formed at the other side to transfer the operation of the click part 312 to the pressure sensing sensor member 320; And a support rib 315 formed between the scroll actuator 313 and the click actuator 314 such that the scroll actuator 313 and the click actuator 314 are not operated simultaneously.

The pressure sensor member 320, the scroll sensing unit 321 is formed on one side to sense the operation of the scroll unit 311 through the scroll actuator (313); A dome receiving portion 322 formed on the other side to accommodate the dome member 330; A click sensing unit 323 formed between the scroll sensing unit 321 and the dome receiving unit 322 to sense the operation of the click unit 312 through the click actuator 314; And a connector connection part 324 formed at one end thereof to be connected to the connector 340 provided on the printed circuit board 200.

3 to 7, in the front of the side button 310, the scroll portion 311 which is the center portion of the side button 310 is easy to scroll the content embedded in the main body 100 One or more clicks 312 positioned on any one of the left and right sides or both the left and right sides of the scroll unit 311 may be positioned more easily than the scroll unit 311 so that the position can be easily and easily recognized at the time of clicking. It is preferably formed in a protruding shape.

In addition, when the user touches the scroll unit 311 as if the user rubs the button using a hand on the back of the side button 310, the scroll actuator 313 scrolls the pressure sensor member 320. The pressure is sequentially applied to the sensing unit 321 to transfer the pressure to the printed circuit board. In this case, when the scroll unit 311 is operated, it is preferable to form a support rib 315 between the scroll sensing unit 321 and the click sensing unit 323 so as not to click.

In addition, when the click unit 312 is pressed to select contents embedded in the main body 100, the dome member 330 is pressed to generate a click feeling, and the click actuator 314 of the pressure detecting sensor member 320 is selected. The click sensing unit 323 is transferred. In this case, an interval between the click actuator 314 and the click sensing unit 323 may be larger than an interval between the scroll actuator 313 and the scroll sensing unit 321 so that the dome member 330 is pressed and sensed. . In addition, as described above, the support rib 315 is supported so as not to be scrolled when the click unit 312 is operated.

As such, in order to prevent the support rib 315 from being simultaneously scrolled and clicked, it is preferable that a sensing area is not provided at the pressure sensing sensor member 320 to which the support rib 315 contacts.

Here, when the connector connecting portion 324 formed on one side of the pressure sensor member 320 is connected to the connector 340 of the printed circuit board 200 to operate (scroll or click) the side button 310 The signal signal is transmitted to the printed circuit board 200.

In addition, as shown in Figure 7, the interval between the scroll actuator 313 and the scroll sensing unit 321 is 0.1mm, the back of the side button 310 where the dome member 330 is located and the pressure sensing sensor member ( The spacing between 320 is 0.3 mm, and the spacing between the click actuator 314 and the click sensing unit 323 is preferably 0.15 mm.

The operation of a portable device having a side key module having a scroll and click function of the present invention configured as described above will be further described with reference to the accompanying drawings.

As shown in FIGS. 1 to 7, when a user uses a portable device (eg, a mobile communication terminal), the scroll unit 311 of the side button is used to scroll or adjust the volume of the contents embedded in the main body 100. When the user touches the button up and down using his or her hand, the scroll actuator 313 provided in the side button 310 is pressed and the scroll function is sequentially applied to the scroll sensing unit 321 of the pressure sensor member. It works. At this time, the connector connecting portion 324 of the pressure sensor member is connected to the connector 340 of the printed circuit board, the signal signal of the scroll operation is transmitted to the printed circuit board 200.

Similarly to the above-described operation, when the user clicks (presses) the click portion of the side button when the user selects the content embedded in the main body 100, the dome member 330 is first pressed to generate a click feeling, and then the side button. The click actuator 314 provided in the 310 is pressed and sensed by the click sensing unit 321 of the pressure sensing sensor member, and the signal signal of the click operation is transmitted to the printed circuit board 200.

At this time, the support rib 315 is configured between the scroll actuator 313 and the click actuator 314 so that the scroll and click operations are not performed simultaneously.

Although the mobile communication terminal has been described as an example in the present embodiment, the present invention is not limited thereto and may be applied to all digital multimedia portable devices.

The present invention described above is not limited to the above-described embodiment and the accompanying drawings, and various substitutions, modifications, and changes are possible within the scope without departing from the technical spirit of the present invention. It will be apparent to those who have knowledge.

As described above, the present invention has an effect that the scroll (search) and selection (click) functions can be simultaneously performed as one member by using the pressure sensor member.

In addition, since the present invention can apply a search and selection function, there is an effect that various contents and software can be embedded in the device body.

In addition, since the present invention solves scrolling and clicking at the same time by using the pressure sensor member, there is no need for components such as a conventional flexible printed circuit board (fpcb) or tact switch (tact s / w), there is also an effect of cost reduction .
