FIG. 2 is a view for explaining a use process of the terminal case of FIG. 1. FIG.
3 is a use state view of the terminal case of Fig.
Figure 4 is a side view of Figure 3;

Hereinafter, the features and advantages of the present invention will be described in detail with reference to the accompanying drawings. The terminal according to the present invention is an image display device having a convenient and easy to use, for example, a so-called cell phone, a PDA, a tablet PC, and the like.

Referring to FIG. 1, a mobile phone case according to the present invention is indicated by reference numeral 10. The case 10 includes a main body 11 for accommodating the cellular phone P, a lens 12 formed on the main body 11, and a holder 13.

The main body 11 is formed with a receiving space corresponding to the standard of the cellular phone P (reference symbol 'S' in FIG. 3) so that the rear surface R of the display screen D of the cellular phone P And is configured to be detachably seated in the accommodation space (S). In the present embodiment, the main body 11 integrally includes a 'C' type fastening part 14 protruding along the edge and holding a corner part of the mobile phone P seated thereon, do.

The configuration of the accommodation space S and the fastening part 14 is not different from that of a conventional cellular phone case, and the fastening part 14 may be realized in different forms as needed. However, when the case 11 is used as a means for viewing an image of the cellular phone P, the coupling unit 14 may be used as a cover-board for shielding the light around the user's eyes, (14) has a meaning.

The lens 12 is a lens installed on the bottom surface of the main body 11, and two lenses 12 are arranged with a predetermined interval, as in glasses. The lens 12 may be applied to any type of stereoscopic image such as 3D or VR, or a lens for viewing a picture, without limitation to any lens capable of viewing a stereoscopic image, a fisheye lens type, a polarized spectacle type, and other stereoscopic images. In this embodiment, the lens 12 is separately provided and attached to the main body 11. However, the main body 11 and the lens 12 may be integrally injected by inserting the main body 11 or by designing the lens structure in the injection itself.

The cradles 13 are provided as a pair and are rotatably coupled to the main body 11 by a hinge 15 so that the main body 11 is separated from the main body 11 when the main body 11 and the mobile phone P are separated, The holder 12 can be mounted on the edge of the cellular phone P or the ear of the body and in the case of the former illustrated in the present embodiment the holder 13 serves as a spacer, So that the display screen D is opposed at regular intervals. For example, in the latter case, it may be necessary to design the length of the holder 13 effectively.

The body 11 has a hinge boss 15a protruding from the main body 11 in correspondence with the cradle 13. [

Preferably, the cradle 13 is configured by cutting off one surface on the bottom side of the main body 11 that provides the accommodation space S. For example, when the holder 13 is separately formed and fastened to the main body 11, the manufacturing cost is increased and the manufacturing process becomes complicated. Therefore, the main body 11 becomes thick and the holder 13 may be damaged. On the other hand, in the present embodiment, the cradle 13 is constructed by cutting the main body 11 on the same plane so that the opposite advantage can be obtained.

Specifically, the cradle (13) has a clip structure which is resiliently fitted in the corner of the cellular phone (P). To this end, the cradle 13 includes a base 14a connected to the hinge 15 in the form of a letter 'A', a substantially 'C' type fitting groove 16 ', extending from the base 13a, And an elastic piece 13b which forms the elastic piece 13b.

Meanwhile, in the present invention, it is difficult to use a planar lens technically as a lens to be used for viewing a stereoscopic image. Therefore, a special convex lens is used. In this case, when the convex lens is convex toward the cell phone P, the case 10 becomes inconvenient to accommodate the cell phone P. It is preferable that the lens 12 is convex in the direction opposite to the cellular phone P in a state where the main body 11 accommodates the cellular phone P. [

In this case, however, the lens 12 may come into contact with an arbitrary bottom surface, which may cause scratches or other surface damage. In order to prevent the surface of the case 10 from being damaged by the contact of the exposed lens 12 with the corresponding surface of the body 11, that is, an arbitrary bottom surface, the case 10 is provided with a lens And further includes a protective projection 17. That is, the protrusion 17 can protect the lens 12 from contact with the bottom surface of the case 10 by allowing the case 10 to maintain a predetermined height level from any bottom surface.

Such a method of protecting the lens 12 can be effectively achieved by arranging the hinge boss 15a and the projection 17 at appropriate positions.

2, when the case 10 is coupled to the cellular phone P, the main body 11 and the cellular phone P are separated from each other if the edge coupling part 14 of the main body 11 is opened. The fitting grooves 16 formed at the ends and the ends of the cradle 13 are fixed to the main body 11 or the lens 11 by rotating the pair of cradles 13 opposed to each other by 90 degrees (12).

In this state, when the edge of the mobile phone P is inserted into the fitting groove 16, the case 10 is mounted on the mobile phone P.

3 and 4, the lens 12 and the display screen D of the cellular phone P are opposed to each other while the case 10 is mounted on the cellular phone P, Serves as a spacer to maintain a constant gap between the lens 12 and the display screen D of the mobile phone P. [ In this state, the user can view the stereoscopic image provided by the cellular phone P through the lens 12. At this time, as described above, the fastening part 14 is not complete but blocks the light around the user's eyes It can be used as a cover-board.

In the above description, the case 10 of the present invention is mounted on the corner of the cellular phone P. However, as the length and shape of the cradle 13 using the main body 11, the direction of the lens 12, and the like are effectively designed, the case 10 may be mounted on the ear of the body to be used as the glasses type . In this case, the case 10 can be used more conveniently without being limited by the position of the cellular phone P, the direction or the like.
