As shown in the drawings, an eye protective cover capable of supporting multi-purpose contents according to the first embodiment of the present invention includes front and back covers 20 and 30 which are foldably coupled to each other by a main coupling part 10. Front and back collapsing covers 25 and 35 are coupled, respectively, to the upper surfaces of the front and back covers 20 and 30 by corresponding separation lines 25a and 35a, in such a way as to overlap the front and back covers 20 and 30. Angle holding units 40 are provided between the front cover 20 and the front collapsing cover 25 and between the back cover 30 and the back collapsing cover 35 to hold an angle between the front cover 20 and the front collapsing cover 25 and an angle between the back cover 30 and the back collapsing cover 35.

As shown in FIG. 3, a detachable support unit 60 is provided on any one of the main coupling part 10 and the front and back covers 20 and 30, and functions to detachably support a page unit (not shown) on which various pieces of information may be printed or on which a memo may be taken.

As shown in the drawings, the separation line 25a which couples the front collapsing cover 25 to the front cover 20 is formed on the upper portion of the front cover 20, and the separation line 35a which couples the back collapsing cover 35 to the back cover 30 is formed on the upper portion of the back cover 30. Of course, the separation lines 25a and 35a may be formed, respectively, on the uppermost end of the front cover 20 and the uppermost end of the back cover 30.

The main coupling part 10 is connected at opposite side edges thereof to the front cover 20 and the back cover 30 via separation lines 10a.

The front cover 20 has a stepped surface 20a which is thinner than the front cover, and the back cover 30 has a stepped surface 30a which is thinner than the back cover.

The front collapsing cover 25 fits inside the stepped surface 20a, and is connected to the front cover 20 via the separation line 25a. Here, the thickness of the front collapsing cover 25 is determined such that the total thickness of the overlapping stepped surface 20a and front collapsing cover 25, when the front collapsing cover fits inside the stepped surface 20a, is the same as the thickness of the front cover 20.

The back collapsing cover 35 fits inside the stepped surface 30a, and is connected to the back cover 30 via the separation line 35a. Here, the thickness of the back collapsing cover 35 is determined such that the total thickness of the overlapping stepped surface 30a and back collapsing cover 35, when the back collapsing cover fits inside the stepped surface 30a, is the same as the thickness of the back cover 30.

Here, the front collapsing cover 25 and the back collapsing cover 35 are coupled to a subsidiary coupling part 15 via separation lines 25b and 35b.

Detachable attaching parts 26a and 26b are provided on the corners of the front cover 20 and the front collapsing cover 25 to maintain the overlapping state of the front collapsing cover 25 with the front cover 20. Further, detachable attaching parts 36a and 36b are provided on the corners of the back cover 30 and the back collapsing cover 35 to maintain the overlapping state of the back collapsing cover 35 with the back cover 30.
