Hereinafter, embodiments of the present invention will be described with reference to the drawings.
(Embodiment 1)
FIG. 1 is a schematic perspective view of the portable terminal device according to the present embodiment.

  Hereinafter, the first embodiment will be described on the assumption that a stereo viewer is mounted on a portable terminal device. However, the same applies to a case where the stereo viewer is mounted on a thin electronic device having a display element such as a portable car navigation system or a television. It is.

  In addition, although the description will be made assuming that the display screen is divided into two and the left and right images are displayed on the respective screens and the stereoscopic image is displayed through the binocular lens, the same image may be displayed instead of the left and right images. At this time, the screen of the display element can be enlarged and viewed by passing through a binocular lens.

  FIG. 1 is a schematic structural diagram of the stereo viewer according to the first embodiment.

  FIG. 1 (1) shows a form of a stereo viewer when mounted on a portable terminal.

  FIG. 1B shows a form of the stereo viewer in a state where it is detached from the portable terminal and folded.

  FIG. 1 (3) shows a configuration diagram when a stereo viewer is attached to the portable terminal.

  The stereo viewer includes an arm 1, a binocular lens 2, a partition plate 3, and support means 4.

  The arm 1 and the binocular lens 2 are coupled by a first hinge having a first rotation shaft 5, and the first angle formed by the arm 1 and the binocular lens 2 can be changed from at least 0 degrees to 90 degrees.

  The partition plate 3 and the arm 1 are connected by a second hinge having a second rotation shaft 5. The second angle formed by the arm 1 and the partition plate 3 can be changed at least from 0 degree to 90 degrees.

  As shown in FIG. 1 (1), the second rotation axis passes through the center of the first hinge, that is, the center line between the two lenses of the binocular lens, and is substantially perpendicular to the first rotation axis. The binocular lens 2 and the arm 1 can be supported so as to be vertical when the partition plate stands upright with respect to the arm surface.

  The supporting means 4 is coupled by a third hinge having a third rotating shaft 7, and the third angle formed by the arm 1 and the supporting means 4 can be changed to 0 ° or more, and the first rotating shaft 5 and the third rotating shaft The axis 7 is substantially parallel.

  As shown in FIG. 1 (3), the stereo viewer is fixed to the casing of the portable terminal with the display element sandwiched between the support means 4 and the partition plate 3.

  In the first embodiment, it is assumed that the arm 1 and the support means 4 have a plate shape, but may have a rod shape, for example. A plate-like shape is desirable for thinning when folded.

  FIG. 2 shows a cross-sectional structure diagram for explaining details of the method for attaching and detaching the stereo viewer.

  3 (1) and (2) are perspective structural views of the stereo viewer. FIG. 3 (3) is a plan view of the stereo viewer.

  FIG. 2 (2) shows a state where the support means 4, the partition plate 3, and the binocular lens 2 are set up vertically with respect to the arm 1 from the folded state of FIG. 2 (1).

  The partition plate 3 has a second side 13 on the side surface close to the binocular lens 2, has a first side 12 on the side surface close to the support means 4, and both the first side and the second side have the second rotation shaft 6. And vertical.

  When the binocular lens 2 is in contact with the second side, the binocular lens 2 can be held perpendicular to the arm.

  Here, in order to make the angle between the binocular lens 2 and the arm 1 vertical, the structure is supported by a partition plate, but other means for setting the angle on the first hinge without using the partition plate may also be used. I do not care.

  As shown in FIG. 2 (3), the portable terminal housing 8 is sandwiched between gaps 14 formed between the first side of the partition plate 3 and the support means 4.

  As shown in FIG. 2 (4), when the second side of the partition plate 3 and the display element surface are in contact with each other, the arm 1 and the display element 11 surface are held vertically, and the binocular lens 2 and the display element 11 are separated by a specific distance. Can only be placed apart and in parallel.

  As shown in FIG. 2 (5), for example, a spring 15 is incorporated in the third hinge 7 of the support means 4, and a force is applied in a direction in which the third angle formed by the support means 4 and the arm is directed to 0 degrees. It has become. Therefore, a part of the support means 4 has a function of contacting the back surface of the housing 8 and fixing the housing.

  Here, the case where the first side and the second side are perpendicular to the second rotation axis 6 has been described. However, if the first side and the second side are parallel, the first side and the second side are the second time. The moving axis need not be completely perpendicular. However, if it deviates greatly from the vertical, the arm surface of the stereo viewer is inclined from the horizontal, and it becomes difficult to stably attach the mobile phone to the portable terminal, so the first side and the second side are perpendicular to the second rotation shaft 6. It is desirable.

  As described above, “vertical” in the present embodiment means that the angle between certain parts is 90 degrees, but there may be a deviation of several degrees.

  The distance between the binocular lens 2 and the display element 11 is determined by the length of the partition plate 3 in the second rotation axis direction. By setting the value slightly smaller than the focal length of the two convex lenses of the binocular lens, the user can enlarge and display the display screen through the lens.

  Further, when a function of changing the length of the arm 1 or the partition plate 3 in the second rotation axis direction is added, the user can freely adjust the distance between the binocular lens 2 and the display element 11 according to the user's visual acuity. However, in this embodiment, a description of a specific structure example is omitted.

  As shown in FIG. 3 (3), the first rotation shaft 5 that couples the arm 1 and the binocular lens 2 and the second rotation shaft 6 that couples the arm 1 and the partition plate 3 are vertical, and the partition plate 3 is When folded, the second side 13 overlaps the first rotation shaft 5. Thereby, the binocular lens 2 and the arm 1 can be made vertical when the partition plate is erected vertically with respect to the arm surface.

  The first side 12 of the partition plate is perpendicular to the second rotation shaft 6. When the partition plate is folded, the first side 12 is parallel to the third rotation shaft 7, and a gap 4 exists between the first side 12 and the third rotation shaft 7.

  In order to prevent the binocular lens from protruding from the arm when the binocular lens 2 is folded, the length A2 of the arm 1 in the first rotation axis direction is smaller than the binocular lens length A3.

  Since the partition plate 3 is arranged at the boundary between the left and right screens of the display element in a state where it is attached to the mobile terminal, the partition plate 3 does not hinder stereoscopic display. Rather, the presence of the partition plate makes it possible to separate the left and right screens, and has the advantage of facilitating stereoscopic viewing.

  Therefore, it is desirable that the length A1 of the first side of the partition plate 3 is equal to the boundary line of the left and right screens of the display element. However, if A1 exceeds A2 / 2, the partition plate protrudes from the arm width A2 when folded, and therefore, the length A1 of the first side 12 of the partition plate 3 is preferably smaller than half of the arm width A2. .

  With this structure, if the thickness of the portable terminal casing is smaller than the gap 4, the stereo viewer can be easily attached.

  FIG. 3 (4) shows a structural example in which the fourth rotation shaft 16 is further provided and the stereo viewer of FIG. 3 (1) is further folded once. Since this reduces the size, for example, as shown in FIG. 3 (5), the stereo viewer can be easily carried by fixing it to the back surface of the portable terminal housing. For example, a magnet is used for fixing, but other methods may be used.

  FIG. 4 shows a configuration diagram when a Fresnel lens is used as a binocular lens. By using a Fresnel lens, for example, the lens thickness can be reduced to about 1 mm or less, and the stereo viewer can be reduced in thickness.

  As shown in FIG. 4 (2), it has a Fresnel lens surface 17 on which a Fresnel lens is formed and a flat surface 18, and the Fresnel lens surface 17 desirably faces the partition plate 3 side.

  This is because the dotted optical path crosses the flat surface 18 almost perpendicularly as shown in FIG. 4B, so that the image viewed through the lens is hardly distorted.

  If the Fresnel lens surface 17 is arranged on the side opposite to the partition plate 3, the angle between the optical path and the flat surface 18 is not vertical as shown in FIG.

  Since the Fresnel lens processed surface 17 is easily damaged, the transparent plate 19 can be prevented from being damaged by overlapping the Fresnel lens surface 17 as shown in FIG.

  It is desirable that both surfaces of the transparent plate 19 have antireflection films. An air layer is required between the transparent plate and the Fresnel lens processed surface 17, and it is desirable to fix the periphery with an adhesive 20 or the like as shown in FIG.

  Further, in order not to damage the Fresnel lens 2 and the display element surface, an elastic material 21 such as rubber is applied to the first side 12 and the second side 13 of the partition plate 3 as shown in FIG. Provide. Thereby, the partition plate 3 can prevent the lens and the display element surface from being scratched. Further, it is possible to prevent the partition plate 3 from slipping with respect to the lens surface and the display element surface, and to prevent the stereo viewer from being displaced.

With the above configuration, a stereo viewer that is foldable, thin, and easy to carry can be realized.
(Embodiment 2)
FIG. 5 is a perspective structural view of the stereo viewer according to the second embodiment. The basic structure and the like are the same as those in the first embodiment, and a description thereof will be omitted.

  A difference from the first embodiment is a fixing method using a supporting means.

  As shown in FIG. 5 (1), two or more screw holes 23 are formed in the support means, and the two screw holes are located on the opposite side across the partition plate 3. It is possible to fix the rear surface of the housing with the screw 22 fixed to the screw hole 23.

  A stopper 24 is provided so that the third angle between the support means and the arm does not exceed 90 degrees. The spring 15 required in the first embodiment is not necessary.

  A spring may be used instead of the screw.

Other fixing means for fixing the support means and the rear surface of the housing are also conceivable. For example, the position regulation and fixing may be performed by using magnets or providing concave and convex portions on the partitioning plate side surface of the support means and the rear surface of the housing, and fitting the concave and convex portions.
(Embodiment 3)
Next, the stereo viewer according to the third embodiment that can be made thinner than the first embodiment will be described.

  In Embodiment 1, when it folds like FIG. 3 (1), it will become thick by the thickness of a partition plate. Furthermore, as shown in FIG. 3 (4), when it is further folded, there is a problem that the thickness of the partition plate is increased by two, and the mechanism for folding the partition plate itself is complicated. It was.

  FIG. 6 shows the stereo viewer structure of the third embodiment. The arm 1, the binocular lens 2, the partition plate 3, and the support means 4 are plate parts.

  FIG. 6A is a perspective view when the angle formed by the binocular lens 2 and the arm 1, the angle formed by the partition plate 3 and the arm 1, and the angle formed by the support means 4 and the arm 1 are all 180 degrees.

  The arm 1 has a width that is half the length of the long side of the binocular lens, and the arm 1 and the binocular lens 2 are coupled by a first hinge 5. The partition plate 3 has substantially the same width as the arm, and the arm 1 and the partition plate 3 are connected by a second hinge 6.

  A significant difference from the first embodiment is that the arm 1 and the partition plate 3 do not overlap each other by making the width of the arm 1 about half the long side of the binocular lens. Thereby, thickness reduction is attained.

  Further, the binocular lens 2 has a recess 25 in the central portion. A projection 26 is provided at one corner of the partition plate 3 near the binocular lens 2.

  6 (3) and 6 (4), the binocular lens 2 and the partition plate 3 are rotated 90 degrees with respect to the arm 1 about the first hinge 5 and the second hinge 6, and then the depression 25 and the protrusion The binocular lens 2 and the partition plate 3 can be fixed perpendicularly to the arm.

  A complicated fixing function is not required for the first hinge 5 and the second hinge 6.

  FIG. 7 shows a structural diagram when this stereo viewer is fixed to the portable terminal device 8.

  In FIG. 8, the detailed structure of the 1st hinge 5, the 2nd hinge 6, and the 3rd hinge 7 is shown.

  FIG. 8 (2) is an exploded view of the component parts.

  The binocular lens 2 has a first side 26 in the longitudinal direction and a second side 27 parallel to and opposite to the first side 26, and the arm 1 is approximately half the length of the first side 26 of the binocular lens 2. The third side 28 and the fourth side 29 perpendicular to the third side 28 and the fifth side 30 parallel to the third side 28 and perpendicular to the fourth side 29. A sixth side 31 that is approximately half the length of the first side 26, a seventh side 32 that is perpendicular to the sixth side 31, and an eighth side 33 that is parallel to the sixth side 31 and perpendicular to the seventh side 32. Have.

  One half of the third side 28 and the first side 26 is coupled by a first hinge having the first rotation shaft 5, and the fourth side 29 and the seventh side 32 are the second having the second rotation shaft 6. It is connected with a hinge. The support means 4 and the fifth side 30 are connected by a third hinge having a third rotation shaft 7.

  If, for example, a hinge-shaped part is employed as each hinge, the hinge portion becomes thick, and thus it is not suitable for thinning. Therefore, the fixing method shown in FIGS. 8 (3), (4), and (5) is used.

  Any two of the binocular lens 2, the arm 1, the partition plate 3, and the support means 4 are referred to as a first plate-like component 35 and a second plate-like component 36. After arranging the first plate-like component and the second plate-like component so that the respective edges coincide as shown in FIG. 8 (3), the flexible fixing tape component 37 is fixed from the bottom to obtain the plate-like component. The rotation function can be easily realized using the end side of the lower surface of the lens as a rotation axis.

  Thinning is possible because no hinge is required.

  In FIG. 8A, it is assumed that all the tape parts are arranged on the back surface, and the first rotation shaft 5, the second rotation shaft 6, and the third rotation shaft 7 are on the back side. Thereby, bending as shown in FIG. 6 (3) becomes possible.

  FIG. 9 shows a structure in which a fourth rotation shaft 42 is provided in order to fold the stereo viewer into a smaller size.

As shown in FIG. 9 (1), the arm 1 is separated into the first arm 38 and the second arm 39 with the fourth rotation shaft 42 as a boundary, and then coupled with the fourth rotation shaft 42.
The partition plate 3 is separated into the first partition plate 40 and the second partition plate 41 with the fourth rotation shaft 42 as a boundary, and is then coupled by the fourth rotation shaft 42.

  The fourth rotation shaft 42 is on the surface side. As a result, as shown in FIG. 9 (2), it can be folded smaller than that of FIG. 6 (2) by rotating 180 degrees around the fourth rotation shaft 42.

  FIG. 10 shows an example of a method for fixing to the mobile terminal device 8.

  A fixing component 43 shown in the figure is fixed to the back surface (the side opposite to the display element) of the portable terminal housing.

  As shown in FIG. 10, the stereo viewer can be easily fixed by sandwiching the plate of the supporting means 4 in the gap between the fixing parts 43.

  The fixing component 43 protrudes from the mobile terminal housing, but may have a structure in which a supporting structure 4 is fixed by forming a hollow structure.

  Moreover, you may fix the support means 4 using a magnet, a spring, a screw | thread, etc.

  The present invention is useful, for example, as a stereo viewer for a mobile terminal device, and can be used for various electronic devices such as a television, a mobile phone, a mobile terminal, and a car navigation system.
