The third operation unit 123c is operated to receive a command for controlling the operation of the mobile terminal 10, and the input content may be variously set. For example, commands such as power on / off, start, end, scroll, etc., control of the volume of sound output from the first and second

sound output units

152a and 152b, and the touch recognition mode of the display unit 151. Commands such as switching, obtaining fingerprint information, and the like.

The third operation unit 123c may be referred to as a 'back input unit'. The rear input unit 123c may be implemented in a form capable of input by a touch input, a push input, or a combination thereof.

The rear input unit 123c may be disposed to overlap the front display unit 151 in the thickness direction of the mobile terminal 10. For example, the rear input unit 123c may be disposed at the upper rear portion of the mobile terminal 10 so that the user can easily manipulate the index using the index finger when the user holds the mobile terminal 10 with one hand. However, the present invention is not necessarily limited thereto, and the position of the rear input unit 123c may be changed.

As such, when the rear input unit 123c is provided at the rear of the mobile terminal 10, a new type of user interface using the same may be implemented. In addition, the touch screen or the rear input unit 123c described above replaces at least some functions of the first operation unit 123a provided in the front of the mobile terminal 10, and thus the first operation unit 123a in the front of the terminal body. If not disposed, the display unit 151 may secure a wider screen.

Meanwhile, the mobile terminal 10 may be provided with a fingerprint recognition sensor 145 (see FIG. 1) for recognizing a user's fingerprint, and the controller 180 may have a fingerprint detected through the fingerprint recognition sensor 145 (see FIG. 1).

When an impact is applied to the mobile terminal 10 from the outside, the shock wave may travel through the first region 151aRG1 and the coupling member FM of the glass 151a. The shock wave propagating through the coupling member FM into the medium may increase in height of the coupling member FM at the position of the bonding groove 148 and thus become weak at the position of the bonding groove 148.
