[0029] Among them, the paper core layer 4 is yellow, which is more eye-friendly when writing;

[0030] The outer cover includes a spine 1 and a front cover 2 and a back cover 3 fixed to its top and bottom ends respectively. The structure of the spine 1 and the front cover 2 and back cover 3 fixed to its top and bottom ends respectively is equivalent to the first cover paperboard, the splice board and the second cover paperboard in the background art "CN201822174158.7".

[0031] A page-turning opening is formed between the spine 1, front cover 2, and back cover 3, connecting the paper core layer 4 to the outside; such as Figure 2 As shown, the page-turning opening is located at the top and bottom ends of the outer cover and its connected right end;

[0032] There is a gap between the edge of the paper core layer 4 and the edge of the cover 2, and there is a gap between the edge of the paper core layer 4 and the edge of the back cover 3; the left end of the paper core layer 4 is fixed, and the upper and lower ends of the paper core layer 4 and its connected right end are evenly spaced relative to the outer periphery of the outer cover layer, that is, the paper core layer 4 is inside the outer cover layer and there is a distance between it and the outer side of the outer cover layer.

[0033] It also includes a protective component 5 that is fixed to the outer cover layer and adhered to cover the page opening, thereby covering the exposed paper core layer 4 to improve the overall protection.

[0034] The specific structure of the protective component 5 is shown below:

[0035] The cover assembly 5 includes a cover plate 51 that fits against the right end of the cover 2 and the back cover 3, two sets of side plates 52 that are symmetrically fixed to the front and rear sides of the left end of the cover plate 51, side slots 53 respectively located at the bottom end of the cover 2 and the top end of the back cover 3, two sets of abutment plates 54 that are symmetrically fixed to the front and rear sides of the right end of the spine 1, and a front slot 55 located at the right end of the abutment plate 54; the cover 2 and the back cover 3 have a certain thickness to allow for the formation of the side slots 53.

[0036] The side slot 53 and the abutment plate 54 are at the distance mentioned above. The top and bottom ends of the side plate 52 are movable in the side slot 53, and the left end of the side plate 52 extends into the main slot 55 and is movable.

[0037] Pre-made as Figure 4The structure shown can be partially modified by using a fixed abutment 54 at the right end of the spine 1 as a component to support the left side of the outer cover and to cover the area.
