In this case, the touch screen (or touch sensor) itself may be classified as a proximity sensor.

On the other hand, for convenience of explanation, the action of allowing an object to be recognized as being positioned on the touch screen by being approached without contacting an object on the touch screen is called "proximity touch", and the touch The act of actually touching an object on the screen is referred to as "contact touch". A position at which an object is touched in proximity on the touch screen means a position at which the object is vertically corresponding to the touch screen when the object is touched in proximity.

More specifically, the photo sensor scans the contents placed on the photo sensor by mounting a photo diode and a transistor (TR) in a row/column and using an electrical signal that changes according to the amount of light applied to the photo diode. That is, the photosensor calculates the coordinates of the sensing target according to the amount of light change, and through this, the location information of the sensing target may be obtained.

However, when the data reception state of the second SIM 162 corresponds to the AUTO DDS trigger condition [S930], this is a state in which the data reception state through the second SIM 162 is very poor. The second SIM 162 is switched to the first SIM 161 [S950].

Then, after switching to the first SIM 161, the controller 180 drives the second timer T2 operated for a second time longer than the first time [S960]. Preferably, the second timer can be driven for 60 seconds.

Then, after the driving of the second timer is completed, the controller 180 determines again whether the data reception state of the first SIM 161 corresponds to the AUTO DDS trigger condition described above [S970].

When the data reception state of the first SIM 161 does not correspond to the AUTO DDS trigger condition, the controller 180 is in a good state of the data reception through the first SIM 161, so the first SIM 161 Maintain the connection of [S990].

However, when the data reception state of the first SIM 161 corresponds to the AUTO DDS trigger condition [S980], this is a state in which the data reception state through the first SIM 161 is very poor. The first SIM 161 is switched back to the second SIM 162 [S250].
