The second image input unit 141 may have a photographing direction substantially opposite to that of the first image input unit 115 (see FIG. 1), and may be a camera having different pixels from the first image input unit 115.

For example, the first image input unit 115 has low pixels so that it is easy to capture a face of a user in the case of a video call or the like and transmit the face to a counterpart, and the second image input unit 141 photographs a general object It is preferable to have a high pixel because it is often not transmitted.

A flash 142 and a mirror 143 are additionally disposed adjacent to the second image input unit 141. The flash 142 illuminates the subject when the subject is photographed by the second image input unit 143.

Referring to this figure, a recessed receiving portion 121 is formed in the rear case 112. [ A seating part 121a on which the battery 122 is seated is formed at the center of the receiving part 121. [ The seat portion 121a is configured to have a size corresponding to the appearance of the battery 122 so that the battery 122 can be seated. The battery 122 supplies electricity to at least one component of the portable terminal 100. The mounting portion 121a may be provided with a connection terminal 124 connected to the battery 122.

The conductor 123 is formed to extend along the edge of the accommodating portion 121. The body 123a of the conductor 123 may be formed in the form of a long metal foil in one direction. A connection terminal 123b, which is electrically connected to the control unit 160, protrudes from one end of the body 123a. The connection terminal 123b may be formed such that one end of the body 123a is bent.

The receiving end 121b is formed in a region adjacent to the edge of the receiving portion 121 so as to form an end with the receiving portion 121a. As shown, the receiving end 121b may be formed long in one direction along the edge of the seating part 121a. The receiving end portion 121b may increase the structural strength of the rear case 112 surrounding the battery 122 and protect the battery 122 from external impacts.

A conductor 123 is mounted on the receiving end 121b. Such mounting can be implemented in a variety of ways. For example, there is a method in which the conductor 123 is disposed at the receiving end 121b and the body 123a is fused to the receiving end 121b by the heat applied to the body 123a. Mounting of the conductor 123 can be realized by a double injection method in which the conductor 123 is inserted into the injection mold and the rear case 112 in which the receiving end 121b is formed is injected.

An insulating material 125 may be disposed on one surface of the conductor 123 so as to cover the conductor 123. This has the advantage of allowing the user to be charged from the conductor 123. The insulating material 125 may be, for example, an insulating tape or the like.

In general, one end 123c of the conductor 123 constituting the antenna unit must be spaced apart from other surrounding conductive material by a predetermined distance so as not to be electrically grounded. Since the conductor 123 is connected to the circuit board 118 through the through hole 121c, the rear case 112 is disposed between the conductor 123 and the electronic components such as the circuit board 118. [ One end 123c of the conductor 123 is formed to be spaced apart from the electronic components of the portable terminal 100, for example, the circuit board 118 and the like. The antenna portion of the structure that is slimmed by the conductor 123 and the receiving end 121b of this type can be formed.

Referring to Fig. 5, the battery 122 includes a battery cell 122a and a cover 122b. In the battery cell 122a, electricity is charged to be the power source of the portable terminal. In general, the battery cell 122a may include metal water and may be surrounded by metal water. The outer appearance of the battery 122 is formed by a cover 122b surrounding the battery cell 122a. The cover 122b is formed of a non-conductive material such as synthetic resin. Therefore, one end 123c of the conductor 123 mounted on the receiving end 121b is at least spaced apart from the metal by the thickness of the cover 122b.

The built-in conductor 231 may be connected to the circuit board 218 to transmit and receive wireless electromagnetic waves of the first frequency band. For example, the filter portion of the circuit board 218 connected to the embedded conductor 231 filters frequencies of 900 to 1800 Mhz and the embedded conductor 231 is in a form suitable for transmitting and receiving frequencies of 900 to 1800 Mhz . The shape of the built-in conductor 231 can be selected experimentally or simulated.

The conductor 223 may be connected to the circuit board 218 to transmit and receive wireless electromagnetic waves of a second frequency band different from the first frequency band. The first frequency band may be a frequency band other than the frequency band related to Bluetooth or GPS, for example, a frequency band for a call of the mobile terminal or the like. The second frequency band may be a frequency band related to bluetooth or global positioning system (GPS).

Since the built-in conductor 231 and the conductor 223 are formed to be suitable for transmitting and receiving the first and second frequency bands, an antenna unit suitable for transmitting and receiving multiple frequency bands can be formed.

Also, the RF switch 241 may be formed such that a frequency band is selected by a signal input to the portable terminal.

Generally, frequency bands for calling and the like of mobile terminals are different in each country. By providing the switching unit 240, it is possible to form an antenna unit capable of coping with different frequency bands used in different countries. For example, the built-in conductor 231 is formed to be suitable for transmitting and receiving a frequency band used in one country, and the conductor 223 is formed to be suitable for transmitting and receiving a frequency band used in another station.

The RF switch 241 may be connected to a diplexer 242 capable of branching the transmission signal and the reception signal. However, the configuration of the switching unit 240 is not limited to this, and may be implemented in the form of a front end module (FEM) in which an RF switch 241 and a diplexer 242 are formed together.
