A magnet, for example, is mounted as the first element 1334 in the moving part 1331. A Hall IC, for example, is mounted as the second element 221 in the second circuit board 220 in correspondence with the first element 1334. When the second element 221 is composed of a pair of Hall ICs, the first or second signal is generated in accordance with the rotating direction of the moving part 1331. The stopper 1333 protruding from a part of the moving part 1331 moves in the guide slot 1335 of the fixing part 1332. [ At this time, the moving part 1331 and the fixing part 1332 may be connected by an elastic body so that the moving part 1331 is returned to the original position after rotating in one direction. If the moving part 1331 does not return to the home position, a larger number of the second elements 221 may be arranged.

The signal generated by the rotation of the moving unit 1331 may be set as a command for scrolling the menus displayed on the display unit 151 or enlarging / reducing the screen. Alternatively, the above signal may be set as a command for controlling a function related to the camera 121 ', for example, a zoom function, an illuminance adjusting function, a photographing mode adjusting function, and the like.

FIG. 8A is a conceptual view showing the first terminal 211 of FIG. 5, and FIG. 8B is a conceptual view showing a modified example of FIG. 8A.

Referring to FIG. 8A, the first terminal 211 is connected to the first circuit board 210 in the form of a leaf spring or the like. The other end not connected to the first circuit board 210 remains as a free end. The portion adjacent to the free end is bent and becomes stronger against the force applied thereto.

Referring to FIG. 8B, the first terminal 212 may be a coil spring. The coil spring has one end coupled to the first circuit board 210 and the other end remaining as a free end. The coil spring is also robust against the force applied in the direction of compressing it.

According to this configuration, when the first case 101 and the second case 102 are to be coupled, the first circuit board 210 to which the first terminal 211 is coupled is coupled to the first case 101 . And the third operating unit 133 is attached to the supporting portion 1021 in the second case 102. [ The third circuit board 230 extending from the second circuit board 220 of the third operation unit 133 allows the support portion 1021 to pass through the opening portion O. [ The portion of the third circuit board 230 on which the second terminal 231 is formed is attached to the inner surface of the second case 102.

When the second case 102 is coupled to the first case 101, the first terminal 211 and the second terminal 231 disposed at positions corresponding to each other come into contact with each other. As the first terminals 211 are elastically deformed, the contact between them is stably maintained.

The above-described portable terminal is not limited to the configuration and method of the above-described embodiments, but the embodiments may be configured such that all or some of the embodiments are selectively combined so that various modifications can be made. It is possible.
