By carrying out like this, the portable electronic terminal 10 can fully be hold | maintained and the possibility that the portable electronic terminal 10 will remove | deviate and fall or break can be reduced beforehand.

  As shown in FIG. 2, the stereoscopic display tool 30 mainly includes a left-eye lens 32 a and a right-eye lens 32 b that stereoscopically display a stereoscopic image displayed on a display screen (not shown) of the portable electronic terminal 10, A connecting portion 34 that connects the ophthalmic lens 32a and the right eye lens 32b, a left side wall 36a that one end side is foldably connected to the left eye lens 32a, and the other end side is foldably connected to the left bent portion 38a. The right side wall 36b, one end side of which is foldably connected to the right eye lens 32b and the other end side of the right side bent portion 38b, is provided on the upper side of the left eye lens 32a and the right eye lens 32b. The left eyelid part 40a and the right eyelid part 40b, and the shielding part 42 in contact with the connecting part 34, and the portions excluding the left eye lens 32a and the right eye lens 32b are made of paper. As shown in FIG. 3A, the stereoscopic display tool 30 is used by inserting a left bent portion 38a and a right bent portion 38b on the back side of the portable electronic terminal 10 held by the holding portion 24. By doing so, the stereoscopic image displayed on the portable electronic terminal 10 can be stereoscopically viewed.

  The left-eye lens 32a and the right-eye lens 32b (hereinafter also referred to as “lens 32”) are well-known for assisting stereoscopic viewing of a planar image using parallax between the left eye and the right eye. It is a stereoscopic lens and is formed in a substantially square shape. Note that the stereoscopic viewing method may be a vectorogram method, a tranagram method, or another principle.

  The connecting portion 34 is a member that connects the left-eye lens 32a and the right-eye lens 32b. The connecting portion 34 has elasticity capable of positioning the lens 32 when the lens 32 is connected, and bends in the main surface direction of the lens 32. Made of possible members. Examples of such a member include cardboard, a resin plate, a resin film, and the like. By using such a member, the angle formed between the main surface of the left-eye lens 32a and the main surface of the right-eye lens 32b can be changed. By doing so, the lens 32 can be arranged so that the angle of the lens 32 is the optimum angle for each displayed stereoscopic image, so that stereoscopic viewing can be facilitated.

  One end side of the left side wall 36a and the right side wall 36b (hereinafter, also referred to as “side wall 36”) is connected to the left eye lens 32a or the right eye lens 32b so as to be able to bend, and the other end side is connected to the left side. Each of the bent portion 38a and the right bent portion 38b (hereinafter also referred to as “bent portion 38”) is a flat plate-like member connected so as to be bent. When the side wall 36 is used, the distance between the lens 32 and the portable electronic terminal 10 positioned at the bent portion 38 is kept at a predetermined distance, and when stored, the side wall 36 can be folded in the direction of the lens 32 and stored in a space-saving manner. It is an important member.

  The left side collar part 40a and the right side collar part 40b (hereinafter, also referred to as "the collar part 40") are flat members that are connected to the upper part of the lens part 31 so as to be foldable and the end parts are folded. Sometimes, it can be bent substantially at right angles to the lens 32 and can serve as a support member for standing the lens 32 together with the side wall 36. Specifically, even when the foldable collar 40 is inserted into the holding pocket 22 from one end side, the collar 40 and the lens 32 can be folded. The lens 32 can be erected vertically. On the other hand, at the time of storage, the member is folded in the direction of the lens 32 and can be stored in a space-saving manner.

  As shown in FIG. 3C, the shielding part 42 is a member in which the main body part 42a, the connection part 42b, and the fixing part 42c are connected in a foldable manner. The shielding part 42 is connected to the lower side of the lens part 31 by connecting the connecting part 42b to the lower side of the left-eye lens 32a so as to be foldable. In use, after being bent at a substantially right angle between the lens for left eye 32a and the connecting portion 42b, the connecting portion 34 is bent at a substantially right angle between the main body portion 42a and the connecting portion 42b. It abuts and is positioned between the left-eye lens 32a and the right-eye lens 32b. By doing so, the left-eye stereoscopic image can be visually recognized by the right eye via the left-eye lens 32a, or the right-eye stereoscopic image can be visually recognized by the left eye via the right-eye lens 32b. To reduce stereoscopicity and facilitate stereoscopic viewing. At this time, the length of the side of the main body portion 42a on the right eye lens 32b side is formed to be substantially the same as the length of the right eye lens 32b, and the right eye lens 32b is formed in a substantially square shape. Therefore, when the main body 42a and the shield 42 are brought into contact with each other during use, the fixing portion 42c is positioned above the right-eye lens 32b. It can be made to contact | abut to the upper surface side of the left side collar part 40a or the right side collar part 40b by passing between the part 40a and the right side collar part 40b, and bending. By doing so, it is possible to reduce the possibility that the bending of the connection part 42b and the left-eye lens 32a is restored and the position of the shielding part 42 moves. If it adds, since the shielding part 42 can be fixed easily, it can be easily stereoscopically viewed.

  Then, the folding method of the three-dimensional display tool 30 is demonstrated using FIG.3 and FIG.4. Here, FIG. 3 and FIG. 4 are explanatory diagrams for explaining a method of folding the stereoscopic display device 30, and each drawing is an explanatory diagram showing respective processes when the stereoscopic display device 30 is folded. .

  When the stereoscopic display 30 is folded, first, the left side wall 36a is turned to the left side, and the right side wall 36b is turned to the right side, and the bent portion 38 inserted on the back side of the portable electronic terminal 10 is detached (see FIG. 3 (a)). The left side wall 36a and the right side wall 36b are rotated as they are, and the side wall 36 is rotated until the bent portion 38, the side wall 36, and the lens portion 31 are positioned on a substantially straight line. At the same time, the shielding part 42 is rotated to the right to a position on the same plane as the lens part 31, and the fixing part 42c is detached from the upper surface side of the collar part 40 (see FIG. 3B). Subsequently, the main body portion 42a is rotated to the right to the position on the same plane as the lens 32, and the fixing portion 42c is rotated to the right to the position on the same plane as the lens portion 31 (see FIG. 3C). By doing so, the lens part 31, the side wall 36, and the collar part 40 are located on the same plane.

  Subsequently, the portable electronic terminal 10 is rotated together with the other surface side of the cover unit 20 to make the cover unit 20 planar, and the lens unit 31 is rotated in the direction of the cover unit 20, so that the lens unit 31 and the collar unit are rotated. 40 is brought into contact. In this state, the lens unit 31 and the shielding unit 42 can be folded in a compact manner by rotating the shielding unit 42 until it contacts the lens unit 31 (see FIG. 4A). Subsequently, the left side wall 36a and the right side wall 36b are rotated in the direction of the lens 32, respectively, and the side wall 36 and the flange 40 are brought into contact with each other. At this time, by inserting a part of the right side bent portion 38b provided in the right side wall 36b into the fixing hole 37 provided in the left side wall 36a, the side wall 36 and the flange portion 40 can be kept in contact with each other. it can. Thus, by maintaining the state where the side wall 36 and the collar part 40 are in contact with each other, the state where the collar part 40 is in contact with the lens part 31 can also be maintained at the same time (see FIG. 4B).

  Finally, the portable electronic terminal 10 and the three-dimensional display 30 are attached to the cover 20 by folding in half so that the surface of the portable electronic terminal 10 and one surface of the side wall 36 abut at the center of the cover 20. It is housed inside and can be compact and highly portable (see FIG. 4C).

  On the other hand, when the stereoscopic display tool 30 is used, the above-described folding method may be reversed. Specifically, one of the cover parts 20 folded in half at the center is rotated by approximately 90 ° to bring the cover part 20 into a flat state (see FIG. 4B). Subsequently, the right bent portion 38b is detached from the fixing hole 37, the right side wall 36b is rotated to the right side, and the left side wall 36a is rotated to the left side, so that the lens portion 31 and the side wall 36 are positioned on substantially the same plane. (See FIG. 4A).

  Next, while rotating between the collar part 40 and the lens part 31 by about 90 degrees, the shielding part 42 is rotated in the direction away from the lens part 31, and the lens 32, the collar part 40, and the shielding part 42 are substantially the same. It is assumed that it is located on a plane. Subsequently, the portable electronic terminal 10 is rotated by approximately 90 ° (see FIG. 3C). By doing so, the portable electronic terminal 10 and the lens 32 are arranged at positions substantially parallel to each other.

  Next, the main body part 42a is rotated by approximately 90 ° in a direction approaching the connection part 42b and the portable electronic terminal 10 about the connection between the connection part 42b and the main body part 42a (see FIG. 3B). Subsequently, the collar portion 40 is rotated by approximately 90 ° in the direction of the lens 32. Specifically, the collar portion 40 is rotated by approximately 90 ° about the axis between the left-eye lens 32a and the connection portion 42b. Thus, the shielding part 42 is positioned between the left-eye lens 32a and the right-eye lens 32b. At this time, the fixing part 42c can be brought into contact with the upper surface side of the left hook part 40a or the right hook part 40b by passing between the left hook part 40a and the right hook part 40b and bending it. By doing so, it is possible to reduce the possibility that the bending of the connection part 42b and the left-eye lens 32a is restored and the position of the shielding part 42 moves.

  Next, the left side wall 36a is rotated in the right direction and the right side wall 36b is rotated in the left direction, and the folded bent portion 38 is bent (see FIG. 3A), so that the cover portion 20 and the portable electronic terminal 10 are folded. Insert between. By doing so, the distance between the lens 32 and the portable electronic terminal 10 is positioned by the side wall 36 at a predetermined distance (distance corresponding to the length of the sidewall 36), and the display is performed on the portable electronic terminal 10. The stereoscopic image thus obtained is positioned at an appropriate distance for stereoscopic viewing. In addition, by inserting the bent portion 38 between the cover portion 20 and the portable electronic terminal 10, the possibility that the side wall 36 opens in the outward direction can be reduced. In other words, it is possible to position the lens 32 at an optimal position for stereoscopic viewing and reduce the possibility that the position moves.

  At this time, when the length in the left-right direction of the lens unit 31 is longer than the length in the left-right direction of the portable electronic terminal 10 held by the holding unit 24, the portable electronic terminal 10 and the side wall 36 are in contact with each other. When the bent portion 38 is inserted to the contact position, the connecting portion 34 is bent, and the left-eye lens 32a and the right-eye lens 32b are bent at a predetermined angle. By doing so, the stereoscopic image displayed on the portable electronic terminal 10 can be stereoscopically viewed more clearly. In addition, since the width in the left-right direction of the collar portion 40 is formed so as to become shorter from the side connected to the lens 32, the left-eye lens 32a and the right-eye lens 32b have a predetermined angle. Even in this case, the possibility that the left bent portion 38a and the right bent portion 38b collide with each other can be reduced. In addition, when the length of the left-right direction of the lens part 31 is shorter than the length of the left-right direction of the portable electronic terminal 10, the connection part 34 will curve in the opposite direction to this case. Even so, stereoscopic viewing is possible.

  The stereoscopic display device 30 according to the present embodiment described in detail above is provided with the side wall 36 and the bent portion 38 so that the side wall 36 and the bent portion 38 can be folded. The lens 31, the side wall 36, and the bent portion 38 can be folded so as to overlap each other when not in use, so that a stereoscopic image displayed on the portable electronic terminal 10 can be easily stereoscopically displayed. After use, the side wall 36 and the bent portion 38 can be folded, so that they can be stored compactly and easily carried.

  Moreover, since the collar part 40 is also foldable, in use, the lens part 32 and the portable electronic terminal 10 can be folded by inserting the collar part 40 between the portable electronic terminal 10 and the cover part 20. The stereoscopic image displayed on the portable electronic terminal 10 can be easily stereoscopically viewed and can be folded compactly and easily carried after use.

  Furthermore, when the side wall 36 is folded in the direction of the lens 32, the lens 32 and the collar 40 are folded in a direction approaching each other, so that the side wall 36 can be folded compactly and easily carried. At this time, since the direction in which the side wall 36 is folded and the direction in which the collar portion 40 is folded are different from each other, the possibility that the folding is unintentionally released can be reduced. In particular, in the present embodiment, this effect is high because the direction in which the side wall 36 is folded and the direction in which the flange 40 is folded are orthogonal to each other.

  Furthermore, the left-eye lens 32a and the right-eye lens 32b are connected by the connecting portion 34 so that the angle between the lenses can be changed, so that the left-eye lens 32a and the right-eye lens 32b are connected. The angle can be adjusted to an angle that allows easy stereoscopic viewing. In other words, the stereoscopic display 30 is easily used for stereoscopic viewing.

  In addition, this invention is not limited to embodiment mentioned above at all, and as long as it belongs to the technical scope of this invention, it cannot be overemphasized that it can implement with a various aspect.

  For example, in the above-described embodiment, the lens 32 is used. However, the lens 32 is not limited to a material using glass, organic glass, resin, or the like, and assists stereoscopic vision by refracting light. For example, a resin film, a polarizing film, or the like may be used. In any case, the same effect as the above-described embodiment can be obtained.

  In the above-described embodiment, the stereoscopic display tool 30 is mainly made of paper as a whole, but may be made of synthetic resin or the like. Also in this case, the same effect as the above-described embodiment can be obtained.

  In the embodiment described above, the cover portion 20 is a cover member that can be folded in half at the center portion. However, as such a material, for example, paper or a synthetic resin sheet may be used. Alternatively, a film or the like may be used. In any case, the same effect as the above-described embodiment can be obtained.

  As shown in the above-described embodiments, the present invention can be used as a video field, particularly as stereoscopic glasses.
