The end portion of the second region 320 in the direction away from the central region 330 may be formed to be connected to or contact with one surface 101 of the first cover 100. The portable terminal 10 provided in the first cover 100 can be set at a predetermined angle with respect to the paper surface by the operation of the support stand 300. [ Here, the predetermined angle is an angle formed by one surface 101 of the first cover 100 and the second cover 200. The predetermined angle may be 120 to 150 degrees. The limitation of this angle is determined by repeated experiments in which the user works in front of the portable terminal 10 while maintaining the state in which the portable terminal 10 does not fall back, ) Can be applied irrespective of the type. More specifically, when the predetermined angle is 120 degrees or less, the central region 330 of the support 300 is not in contact with the guide portion 120 of the first cover 100 when the central region 330 is bent, If the central region 330 of the support base 300 is bent, even if the first cover 100 and the portable terminal 300 contact the guide portion 120 of the first cover 100, The first cover 100 can not be fully supported by the load of the second cover 10.

The magnetic body 121 provided inside the guide part 120 may have a width in the vertical direction with respect to the length direction of the magnetic body 311, 312 in the vertical direction with respect to the longitudinal direction. Accordingly, when the support 300 is bent, the magnetic bodies 311 and 312 provided at the end of the first region 310 or the end of the second region 320 and the magnetic bodies 311 and 312 provided inside the guide portion 120, (121).

Alternatively, the magnetic body 121 provided in the guide part 120 is positioned in the central area 330 and the end face in the direction perpendicular to the longitudinal direction of the magnetic body 121 is perpendicular to the longitudinal direction, And is arranged horizontally with one side surface of the base 103. That is, the magnetic body 121 provided in the guide part 120 is formed to have a length corresponding to only the first area 310 and a part of the second area 320 adjacent to the first area 310 do. Thus, the influence of the magnetic material 121 provided in the guide part 120 on the electrical connection between the battery part 104 accommodated in the receiving groove 103 and the PCB substrate 105 can be minimized.

The first region 310 and the second region 320 may be formed by injection molding using a natural resin or a synthetic resin or may be formed of a light metal such as aluminum. And the second region 320 are not limited. In this case, when the first region 310 and the second region 320 are formed of a metal such as aluminum, a plating layer for preventing corrosion is formed on the outer surfaces of the first region 310 and the second region 320 Not shown) may be formed.

A receiving groove 103 for receiving the battery unit 104 and the PCB substrate 105 and a hook 103a for opening and closing the upper portion of the receiving groove 103 are formed in a lower area of the first surface 101 of the first cover 100, The auxiliary cover portion 400 may be formed of a metal plate. A coupling part (not shown) is formed in a part of the rim of the receiving groove 103 to be coupled with the hook 103a provided in the auxiliary cover part 400. The battery unit 104 and the PCB substrate 105 are electrically connected to each other in the receiving groove 103 and the PCB substrate 105 is connected to the FPCB 25 provided on the keyboard 20 105a.

The battery unit 104 may be a secondary battery, such as a lithium polymer battery, which can be used for several hours to several tens of hours.

The PCB substrate 105 is provided with a communication module (not shown) for Bluetooth communication with the FPCB 25 and a plurality of keys, a touch wheel (Not shown) that can control the operation of the display unit 26b.

The receiving groove 103 may protrude in the direction of the other surface 102 of the first cover 100 and protrude in the left and right directions with respect to the second region 320. The first receiving groove (not shown) and the second receiving groove (not shown) are formed on one surface 101 of the first cover 100 so that the receiving groove 103 corresponds to the second region 320 So that the battery unit 104 and the PCB substrate 105 can be accommodated in each of them.

The auxiliary cover part 400 includes a hook 103a on a region corresponding to the fastening part of the receiving groove 103 so that the upper part of the receiving groove 103 can be opened and closed. Therefore, replacement or repair of the battery unit 104 or the PCB substrate 105 accommodated in the receiving groove 103 can be facilitated.
