In addition, in one embodiment of the present invention will be described by taking two stimulus detection means as an example.

Advantages of the wireless communication terminal may be various, but above all, it is said that the greatest advantage is in the mobility provided to the user who is calling. Due to this mobility, the number of wireless communication subscribers has increased exponentially, and in recent years, wireless communication terminals are widely used by the general public.

However, as time goes by, the merits of mobility have gradually disappeared to users of wireless communication terminals, and a multifunctional wireless communication terminal capable of providing more various additional services is required.

Accordingly, most recently released wireless communication terminals have various functions such as camera function, radio broadcast reception function, music (for example, MP3: MPEG layer 3) playback function, acupressure function, blood glucose detection function, ultrasonic imaging function, etc. It has a function.

In addition, various types of wireless communication terminals such as a foldable subfolder with a folding subbody, a swivel type that can rotate 180 degrees in a predetermined direction while the folder is opened, and a slide type with a sliding subbody are released. There has also been a variety of ways to detect the opening and closing of wireless communication terminals.

Here, a wireless communication terminal having an opening and closing detection function using a conventional single magnetic sensor will be described with reference to FIG. 1.

As shown in FIG. 1, a wireless communication terminal having an opening / closing detection function using a conventional single magnetic sensor includes a magnetic generating means 14 for generating magnetism and a magnet generated by the magnetic generating means 14. The magnetic sensing sensor 15 for sensing and the magnetic sensing sensor 15 receive the undetected signal to transmit power to the display unit 11, and the magnetic sensing sensor 15 receives power. The control unit 16 for controlling the switch 16 to cut off the power transmitted to the display unit 11 by receiving the detection signal according to the detection of the magnetism, and the display unit 11 under the control of the control unit 17. It includes a switch 16 for transmitting or cutting power to the power supply, and the display unit 11 for being activated by receiving power through the switch 16, or deactivated by not receiving power.

Here, the magnetic detection sensor 15 outputs a detection signal (on signal) when detecting the magnetism, and outputs an undetected signal (off signal) when the magnetism is not detected.

Meanwhile, an operation of the controller 17 will be described in more detail with reference to FIG. 2.

As shown in FIG. 2, the magnetic generating means 14 for generating magnetism is located on one side of the subbody 12, and the magnetic sensing sensor 15 is one side of the main body 13, that is, the subbody 12. ) Is located at a part capable of detecting the magnetism from the magnetic generating means 14 when it is closed.

Therefore, when the subbody 12 is closed, the magnetic sensor 15 detects the magnet generated from the magnetic generating means 14 and transmits the detection signal to the controller 17. Then, the controller 17 determines that the subbody 12 is closed and turns off the switch 16 to deactivate the display 11.

In addition, when the subbody 12 is open, since the magnetic generating means 14 is spaced apart from the magnetic sensing sensor 15 by a predetermined distance, the magnetic sensing sensor 15 is generated from the magnetic generating means 14. Since it does not detect magnetism, it transmits an undetected signal to the controller 17.

On the other hand, if the magnetic sensing sensor 15 does not detect the magnetism while the subbody 12 is open, the switch 16 is turned on to activate the display unit 11.

Such a wireless communication terminal having an opening / closing detection function using the conventional single magnetic sensor 15 detects whether the display unit 11 is activated by detecting the opening / closing of the subbody 12 through the single magnetic detecting sensor 15. In order to determine whether the magnetic sensor 15 is incorrectly detecting the opening and closing of the subbody 12 due to the magnetism from the magnetic generating means (for example, a magnet) built in the cradle of the vehicle wireless communication terminal, the display unit ( 11) there was a problem of malfunctioning.

That is, when the subbody 12 is mounted in the holder in the open state, the magnetic sensor 15 detects the magnetism generated from the magnet built in the holder, the controller 17 is the current subbody ( Although 12) is open, it is determined that the subbody 12 is closed, thereby deactivating the display unit 11.

After the elapse of time, the second magnetic pole sensor 43 detects the magnetic pole (S pole) generated from the second magnetic pole generating means 41 and transmits a detection signal to the controller 44, respectively. At this time, the first stimulus detection sensor 42 transmits the detection signal to the controller 44 before the second stimulus detection sensor 43.

Then, the controller 44 detects the closing of the sub-body 47 in response to receiving the detection signal from the first stimulus detection sensor 42 and receiving the detection signal from the second stimulus detection sensor 43 after a predetermined time elapses. The switch 45 is turned off to deactivate the display unit 46.

)경과 후에 제 1 자극감지센서(42)는 제 1 자극발생수단(40)으로부터 발생된 자극(N극)을 감지하지 못하게 되므로, 각각 미감지신호를 제어부(44)로 전달한다. 이 때, 제 2 자극감지센서(43)가 제 1 자극감지센서(42)보다 먼저 미감지신호를 제어부(44)로 전달한다.In addition, when the sub-body 47 is opened in the closed state, the second magnetic pole sensor 43 does not detect the magnetic pole (S pole) generated from the second magnetic pole generating means 41, and the predetermined time (

After the elapse of time, since the first magnetic pole sensor 42 does not detect the magnetic pole (N pole) generated from the first magnetic pole generating means 40, the first magnetic pole detection sensor 42 transmits an undetected signal to the controller 44. At this time, the second magnetic pole sensor 43 transmits the undetected signal to the controller 44 before the first magnetic pole sensor 42.

Then, the controller 44 receives the undetected signal from the second stimulus detection sensor 43 and receives the undetected signal from the first stimulus detection sensor 42 after a predetermined time elapses, thereby opening the subbody 47. In response to the detection, the switch 45 is turned on to activate the display unit 46.
