Rotating hinge 203 is provided inside the folder 200 so as to be horizontally rotatable from the main body 100, and a third inserting portion 203a is provided at the bottom of the rotating hinge 203 for coupling with the hinge barrel 300 to be described later. )

Since the horizontal rotation process of the rotate hinge 203 is already widely used in the related art, a detailed description of the internal structure and operation thereof will be omitted.

The hinge cylinder 300 has an arcuate surface curved at both ends, and includes a second hinge groove 301 corresponding to the first hinge groove 111 of the main body 100, and the insertion groove of the main body 100 ( The dummy hinge 302 is positioned at the position corresponding to 112. The upper portion of the hinge cylinder 300 is configured to include a third hinge groove 303 corresponding to the third insertion portion 203a of the rotate hinge 203.

The hinge 400 is inserted into the first insertion portion 401 having a shape that can be inserted into the first hinge groove 111 of the main body 100 and the second hinge groove 301 provided in the hinge cylinder 300. It is composed of a second insertion portion 402 made of a possible shape and the first insertion portion 401 and the second insertion portion 402 is formed in a structure capable of rotating each of the same rotation axis.

The hinge 400 may have a predetermined cycle angle, and a click hinge configured to be fixed or a free-stop hinge that may be set at various angles according to a user's selection may be applied.

Since the click hinge configured to be fixed with a fixed period of time and the free stop hinge which can be fixed at various angles is already widely used in the related art, a detailed description thereof will be omitted. .

In addition, the dummy hinge 302 serves as a rotating shaft.

Therefore, the hinge 400 is inserted into the first hinge groove 101 of the main body 100 and the second hinge groove 301 of the hinge cylinder 300, and the insertion groove 112 and the dummy hinge 302 are coupled to each other. The third inserting portion 203a of the rotate hinge 203 inside the folder 100 in the third hinge groove 303 in the upper portion of the hinge cylinder 300 in a state of opening and closing in a 180 degree vertical direction. The folder 200 is configured to be rotatable horizontally with respect to the main body 100.
