In such a case, there is an advantage that the configuration (s) disposed in the first rear case 225 in the closed state is protected by the second body 205. Even if the camera 121 of the second body 205 is not separately provided, the camera 121 of the first body 200 is rotatably formed so that the photographing direction of the camera 121 of the second body 205 As shown in FIG.

The terminal 100 shown in Figs. 1 to 3 is operable in a communication system capable of transmitting data through a frame or a packet, including a wired / wireless communication system and a satellite-based communication system .

Hereinafter, a wireless communication system in which a terminal according to an embodiment of the present invention can operate will be described with reference to FIG.

The communication system may use different air interfaces and / or physical layers. For example, wireless interfaces that can be used by communication systems include, but are not limited to, Frequency Division Multiple Access ('FDMA'), Time Division Multiple Access ('TDMA'), Code Division Multiple Access (CDMA), Universal Mobile Telecommunications Systems (UMTS), in particular Long Term Evolution (LTE), Global System for Mobile Communications (GSM) However, the present invention is applicable to all communication systems including a CDMA wireless communication system.

The intersection of sector and frequency assignment may be referred to as a CDMA channel. The BS 270 may be referred to as a Base Station Transceiver Subsystem (BTSs). In this case, the word "base station" may be referred to as a combination of one BSC 275 and at least one BS 270. [ The base station may also indicate a "cell site ". Alternatively, each of the plurality of sectors for a particular BS 270 may be referred to as a plurality of cell sites.

Hereinafter, the channel display method of the terminal according to the present invention will be described with reference to FIG. 5 is a flowchart of a channel display method of a terminal according to an embodiment of the present invention.

As shown in FIG. 5, the terminal 100 receives channel search information through the user input unit 130 (S510).

Here, the channel search information may mean condition information for searching a specific channel among a plurality of channels. For example, the channel search information may include at least one number constituting a channel number, at least one character constituting a channel name, or a number representing a broadcast signal strength. Of course, the channel search information may include all the information that can be a condition for channel search including the above-described ones.

Upon inputting the channel search information, the terminal 100 may be in a state of outputting a broadcast signal provided from a specific channel, or may be in a state of not outputting.

Also, in the input step S510, the terminal 100 may receive a signal (hereinafter referred to as 'command signal') for commanding at least one of input and type of channel search information. For example, the user input unit 130 may include a specific key for receiving a command signal among key pads formed of a plurality of keys. Here, the key may include a button key or a touch key provided on the touch screen.

For example, when an input command signal is input before or after the input of a number or character, the terminal 100 can recognize that the input or input number or character is an input as channel search information.

In addition, when a type command signal is input before and after the input of the channel search information, the terminal 100 can determine the channel search type using the input channel search information.

Here, the input command signal and the type command signal may be generated using the same specific key or may be generated using different specific keys. For example, when the same specific key is used, when there is a specific key input before or after the input of a number or a character, the terminal 100 recognizes that the inputted number or character is an input as channel search information, The channel search type corresponding to the key data can be determined. Alternatively, when different specific keys are used, the terminal 100 recognizes the input number or character as an input as channel search information when a specific key for generating an input command signal is inputted before or after inputting a number or character, If a specific key for generating the type command signal is input, the type of channel search corresponding to the key data can be determined.

As described above, the terminal 100 can receive channel search information, an input command signal, or a type command signal using a key provided on the keypad. Meanwhile, when the terminal 100 is provided with a touch screen, the user can directly write numbers, characters, or symbols corresponding to the channel search information, the input command signal, or the type command signal on the touch screen. Accordingly, the terminal 100 may receive channel search information, an input command signal, or a type command signal through a touch screen.

The input step S510 will be described in detail with reference to Figs. 6A and 6B. 6A and 6B are block diagrams illustrating a process of receiving channel search information in a terminal according to an embodiment of the present invention.

For convenience of explanation, it is assumed in FIGS. 6A to 12 that an input command signal and a type command signal are generated using the same specific key. It is also assumed that the "*" key and the "#" key are used as specific keys. It is also assumed that the terminal 100 receives channel search information during broadcast output.

6A, when a "1" key and a "*" key are input by the user, the terminal 100 transmits the channel search information 151-1 to the numbers "1" and "*" The corresponding type command signal can be input.

6B, when "1 *" is written on the touch screen by the user, the terminal 100 selects the type corresponding to the numbers "1" Command signals can be input.
