It is provided with a groove-shaped seating portion 15, the center of the seating portion 15 is provided with a first coupling portion 16 for coupling a portion of the rotary hinge module 30 to be described later.

Although the seating part 15 shows a state in which the front and both sides of the first body 10 are opened, the present invention is not limited thereto, and only the front of the first body is opened or the front of the first body is not limited thereto. Of course, only the upper surface can be opened.

The second body 20 is coupled to the seating portion 15 formed on the front surface of the first body 10 in a rotatable structure, and the display device (liquid crystal screen, touch screen) for displaying a variety of image information on the front ( 21 and the second coupling portion 22 having the same central axis as the first coupling portion 16 at a position corresponding to the first coupling portion 16 of the first body 10.

The rotary hinge module 30 is provided to enable the rotation even in a state where the second body 20 cannot be rotated as a part of the feature of the present invention. That is, the second body 20 has a difference in length and length of the horizontal and vertical, and the seating portion 15 of the first body 10 also has the same shape as that of the second body 20. Since the second body 20 is formed to have a structure that can not rotate in the state seated on the seating portion 15 of the first body 10, in the present invention, the first body 10 and the second body ( The rotary hinge module 30 is installed on the contact surface of the 20 to enable the rotation of the second body 20.
