In order to couple the first magnet 1020 and the second magnet 220 to each other, the polarity of the second magnet 220 may be different from the polarity of the first magnet 1020 As shown in FIG.

Hereinafter, the arrangement structure of the first magnet 1020 and the second magnet 220 will be described.

FIG. 11 is a conceptual view showing a magnet arrangement structure according to an embodiment of the present invention, and FIG. 12 is a view for explaining a magnet arrangement structure according to an embodiment of the present invention.

11 and 12, a plurality of the first magnets 1020 are arranged symmetrically with respect to a reference line L with respect to a polarity. Also, the plurality of second magnets 220 are arranged so that the polarities of the second magnets 220 are symmetrical with respect to the reference line L.

The reference line L includes a plurality of first magnets 1020 and a plurality of second magnets 1020 which are disposed along the coupling region of the terminal body 100a and the outer cover 200, It is understood as a line. That is, the plurality of first magnets 1020 are divided into the same number of left and right by the reference line L, or the area where the plurality of first magnets 1020 are provided is bisected. The second magnet 220 is also the same.

As shown in FIG. 12, the reference line L divides the plurality of first magnets 1020 so as to have the same number of left and right sides. The mutually symmetrical magnets are formed so that the distances A, B, and C from the reference line L are the same.

In other words, the reference line L can be understood as a line that bisects the coupling region of the first coupling portion 1010 and the coupling region of the second coupling portion 210.

Symmetry of the polarity means that the polarity of one of the plurality of first magnets 1020 is different from that of the other magnet 1022 that is symmetrical with respect to the one magnet 1021 and the reference line L. [ Which are symmetrical with each other. The second magnet 220 is also the same.

According to the above-described magnet arrangement structure, the outer cover 200 can be coupled with the terminal main body 100a in any direction. For example, when the outer surface of the body 210 is referred to as one surface and two surfaces, respectively, the outer cover 200 may be formed such that the one surface is exposed to the outside and the two surfaces are brought into contact with the display portion 151 And may be coupled to the terminal main body 100a. The outer cover 200 may be exposed so that the two surfaces are exposed to the outside, and the one surface may be coupled to the display unit 151. That is, since the number of magnets and the polarity of the first magnet 1020 and the second magnet 220 are symmetrical with respect to the reference line L, And may be coupled to the terminal body 100a.

FIG. 13 is a view for explaining a combination of an outer cover and a terminal body according to a second embodiment of the present invention, and FIG. 14 is a view showing the outer cover of FIG. 13 turned upside down.

13 and 14, the terminal main body 300 according to the present embodiment includes a plurality of first magnets 320 symmetrical to the left and right with respect to a reference line L in the first coupling portion 310, And a plurality of sensing sensors 330 that are symmetrical in the left and right direction with respect to the reference line L at the outside of the first magnet 320.

The detection sensor 330 is disposed on the outer side of the first magnet 320 among a plurality of coupling regions of the first coupling unit 310. The sensing sensor 330 senses the position of the sensing element 424 provided on the outer cover 400 to recognize the inversion of the outer cover 400.

The sensing element 424 is provided on the outer side of the second magnet 420 of the coupling region of the second coupling portion 310. The sensing member 424 is disposed at a position facing the sensing sensor 330 of the plurality of sensing sensors 330 when the second coupling unit 310 and the first coupling unit 310 are coupled to each other . The sensing element 424 is sensed by the sensing sensor 330 and unlike the sensing sensor 330, the sensing element 424 is provided in a region outside the plurality of second magnets 420.

The sensing member 424 may be formed of a magnet having a magnetic force, but may be formed of a variety of metals, plastics, etc., sensed by the sensing sensor 330.

Hereinafter, a process of detecting the inversion of the outer cover 400 will be described. For convenience of explanation, the outer cover in Fig. 13 is defined as a first position, and the outer cover in Fig. 14 is defined as a second position. It is understood that the outer surface of the outer cover 400 is exposed to the outside or the surface of the outer cover 400 that is in contact with the display portion is opposite to the first position and the second position.

When the outer cover 400 is disposed at the first position, the sensing member 424 is sensed on the sensing sensor 332 on the right side of FIG. 13 of the plurality of sensing sensors 330. Therefore, the control unit of the terminal main body 300 can recognize that the outer cover 400 is located at the first position based on the content detected by the right sensing sensor 332.

Next, when the outer cover 400 is turned upside down at the first position, that is, when the outer cover 400 is positioned at the second position, the sensing sensor 331 on the left side of FIG. 14 detects the sensing body 424 . When the outer cover 400 at the first position is turned upside down, the sensing body 424 is moved to the left, so that the sensing sensor 331 recognizes the sensing body 424. Therefore, the control unit can recognize that the outer cover 400 is located at the second position based on the content detected by the left-side sensing sensor 331.

The outer cover 400 can be coupled to the terminal body 300 in any direction by the symmetry of the first magnet 320 and the second magnet 420. In the first embodiment, I look at it.
