The stopper 135 is formed at the upper end of the sliding part 130 and is inclined downward so that the sliding part 130 is fastened to the body part 104 so that the stopper 135 can be easily assembled When the sliding portion 130 is pulled out, the stopper 135 is caught by the stopper rib 145d so as not to be easily detached.

11, ribs 145a, 145b, and 145c protruding toward the inside of the groove 1452a are formed in the rail 1452 such that the sliding portion 130 is held by the body portion 104 when fastened to the body portion 104, ribs are formed. The ribs 145a and 145b are structures for narrowing the passage of the wing 131a. The stopper rib 145d is formed in the vicinity of the stopper rib 145d to prevent upward and downward movement of the sliding part 130 between the sliding part 130 and the guide rail 145, which may occur when the sliding part 130 is drawn out.

The upper end of the rail 1452 may be formed so that the width of the groove gradually decreases toward the end thereof in order to restrict excessive movement of the wing 131a of the sliding portion 130. [ That is, when an inclined portion 145c gradually protruding inward from the groove 1452a of the rail 1452 is formed and the sliding portion 130 is slid to the upper end of the rail 1452, The excessive movement is limited by the frictional force between the inclined portion 145c of the rail 1452 and the wing 131a of the sliding portion 130. [ In addition, the inclined portion 145c also functions to hold the sliding portion 130 so that the sliding portion 130 is slowly drawn out when the sliding portion 130 is drawn out.

The identification module 186 may be connected to the terminal 100 through an input / output port 119 described later.

The input / output port 119 is a path through which power from the cradle is supplied to the mobile terminal 100 when the mobile terminal 100 is connected to an external cradle, A command signal may be transmitted to the mobile terminal 100. The various command signals or the power source input from the cradle may be operated as a signal for recognizing that the mobile terminal 100 is correctly mounted on the cradle.

The present invention described above can be embodied as computer-readable codes on a medium on which a program is recorded. The computer readable medium includes all kinds of recording devices in which data that can be read by a computer system is stored. Examples of the computer readable medium include a hard disk drive (HDD), a solid state disk (SSD), a silicon disk drive (SDD), a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, , And may also be implemented in the form of a carrier wave (e.g., transmission over the Internet). Also, the computer may include a control unit 180 of the terminal. Accordingly, the above description should not be construed in a limiting sense in all respects and should be considered illustrative. The scope of the present invention should be determined by rational interpretation of the appended claims, and all changes within the scope of equivalents of the present invention are included in the scope of the present invention.
