Embodiments of the present invention will be described below based on the drawings.

In the figure, 1 is the main body of the case, which has a rectangular shape, and has an opening 2 on the front side for storing a booklet A such as a reduced size sectional map, and the upper surface has an opening 2 that can be inserted into the storage section 3 through the opening.

Reference numeral 6 denotes a rectangular magnifying lens having a shape corresponding to the viewing window 4, and utilizes a Fresnel lens.

The magnifying lens 6 is constructed by providing a transparent plastic mounting frame 8 around the lower four circumferences of a Fresnel lens 7, and pasting a transparent plastic thin plate 9 for lens protection on the lower surface.

A notch step 10 is formed on the left and right side walls of the case main body 1, and one end 11 of a bending fitting 11 connected thereto in a dogleg shape.
a is pivoted.

The other end 11b of the refractive fitting 11 is pivotally attached to the side surface of the magnifying lens 6, and the magnifying lens 6 is disposed above the transparent window 4.

The magnifying lens 6 can adjust its focal length with respect to the paper surface a of the booklet A stored in the storage section 3 by means of refractive fittings 11.11, and can also maintain its position.

When not in use, the magnifying lens 6 can be pushed down to overlap the case body 1.

Reference numeral 12 denotes a notch provided at the front and rear ends of the case body 1, so that it is easy to hold the finger when pulling up the magnifying lens 6.

By making the bottom plate 1a of the case body 1 also transparent plastic, the whole can be placed on a newspaper, map, etc. without storing the booklet A, and can be used as a normal magnifying lens.

When the booklet A is not in use, it can be stored with the covers 1 and 2 closed, and when viewing under magnification, it is folded back with the designated pages facing up as shown in Figure 5 and stored in the storage section 3 in this state. .

According to the booklet storage case of the present invention, the paper surface of the stored booklet can be enlarged and viewed with a magnifying lens, making it ideal as a storage case for reduced-sized classification maps, etc.
Further, even booklets printed with normal size type can be read without the need for reading glasses.

Furthermore, even if the miniature classification map mentioned above is frequently used, it is always stored in the case, so it will not get dirty or tear.
It has the advantage of being able to withstand long-term use, having a simple configuration, and being able to be provided at low cost.
