Description

  The present invention relates to an eyeglass display.

There is a see-through type eyeglass display as a display capable of displaying an image of a computer or the like superimposed on an image of the outside world, and is described in, for example, Japanese Patent Application Laid-Open No. 2004-12768 (Patent Document 1). In such a display, the light beam corresponding to the image formed by the image forming and projecting apparatus is propagated through the spectacle lens, and the image is reflected in the direction of the eye by a reflecting member such as a half mirror or HOE near the center of the spectacle lens. To display.
Japanese Patent Laid-Open No. 2004-12768

  In the case of normal glasses, it can be easily carried by folding the temples of the glasses, but in the case of such an eyeglass display, an image forming projection device is attached to the temple part, so even if you try to fold the temple inward The eyeglass lens and the image forming / projecting apparatus cannot be folded due to mechanical interference, which is inconvenient to carry.

  The present invention has been made in view of such circumstances, and an object thereof is to provide an eyeglass display that can be easily folded when not in use and is convenient to carry.

  A first means for solving the above problem is an eyeglass-type eyeglass display, in which an eyeglass lens is held by a support including a temple, and an image forming projection device is held by one temple. The light beam emitted from the image forming and projecting device is incident on one of the spectacle lenses (image projection lens) and reflected by the first reflector, and the second reflector passes through the spectacle lens. In this case, the temple or the image forming / projecting device is capable of rotating in the horizontal direction when the eyeglass display is attached to the image projection lens via the first rotation shaft. In the state where the eyeglass display can be used, it is connected so as to be rotatable through a second rotation shaft facing the length direction of the temple. The image forming / projecting device and the image projecting lens interfere with each other so that the first rotation shaft cannot be rotated, and the second rotation shaft is rotated so that the image forming / projecting device and the image are rotated. When the projection lens is positioned so as not to interfere, the first rotation shaft is configured to be rotatable in a direction in which the image forming projection device and the image projection lens are brought close to each other. It is an eyeglass display.

  The second means for solving the problem is the first means, and when the image forming / projecting apparatus and the image projecting lens are in a position where they do not interfere with each other, the light beam emission of the image forming / projecting apparatus An eyeglass display comprising a protective member for protecting the surface.

  According to the present invention, an eyeglass display that can be easily folded when not in use and is convenient to carry can be provided.

  Hereinafter, an example of an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing an outline of an eyeglass display as an example of an embodiment of the present invention. In FIG. 1 (a), the eyeglass display 1 has two spectacle lenses 2 and 3, which are fitted in a frame 4. In one of the eyeglass lenses 3, a mirror 5 and a half mirror 6 are provided to form a video projection lens. An image forming and projecting device 7 is attached to the frame 4 on the image projecting lens 3 side via a connecting portion 8. In the image forming and projecting device 7, an image forming device 7a such as an LCD and a projection lens 7b are provided. A temple 9 is attached to the image forming projection device 7. A temple 10 is attached to the frame 4 on the spectacle lens 2 side.

  FIG. 1B shows an enlarged view of the A portion with the connecting portion 8 as the center. The frame 4 is provided with a rotating shaft 11 (first rotating shaft), and the connecting member 12 is rotatable about the rotating shaft in an in-plane direction of the drawing. However, in the state shown in FIG. 1B, the image projection lens 3 and the image forming / projecting device 7 mechanically interfere with each other, so that they cannot rotate counterclockwise. In addition, a stop mechanism (not shown) prevents rotation clockwise from the state shown in FIG.

  The connecting member 12 has a cylindrical shape, and is fitted into a columnar hole of the image forming projection device 7 so as to be rotatable. This portion is the second rotation axis.

  In the use state shown in FIG. 1, the image formed by the video forming device 7a is projected by the projection lens 7b and enters the video projection lens 3, and is reflected by the mirror 5 as the first reflector to project the video. The light passes through the lens 3, is reflected again by the half mirror 6 that is the second reflector, and is projected onto the eye E.

  When the eyeglass display 1 is folded in a non-use state, the following operation is performed. First, the image forming / projecting device 7 is rotated by 180 ° relative to the connecting member 12 around the second rotation axis to be a position indicated by 7 '. At this time, the temple 9 comes to a position indicated by 9 '.

  From this state, the connecting member 12 is rotated counterclockwise in FIG. 1 with the rotation shaft 11 as the rotation center so that the image forming projection device 7 is positioned at 7 ″ and the temple 9 is positioned at 9 ″. At this time, since the image forming / projecting device 7 is at the position 7 ′ by the rotation about the second rotation axis, the image forming / projecting device 7 and the image projecting lens 3 interfere mechanically. The image forming projection device 7 and the temple 9 can be folded without any problem. Therefore, it becomes convenient to carry.

  In use, the light beam exit surface of the image forming and projecting device 7 is in contact with the image projecting lens 3, so there is no problem that dust or the like sticks to this portion or the surface is scratched. When the projection device 7 is at the position 7 ″, the light beam exit surface of the image forming projection device 7 is exposed, and thus the above-mentioned problem may occur. Therefore, in such a case, the image forming projection device. It is preferable to provide a shutter that covers the light emission surface 7.

  A schematic diagram of this example is shown in FIG. 2, the same components as those shown in FIG. 1 are denoted by the same reference numerals, and the description thereof is omitted. FIG. 2A is a diagram showing a state when the image forming / projecting device 7 is at a position 7 '. The image forming / projecting device 7 is provided with a hinge-type shutter 13, and the shutter plate 13 a covers the light beam exit surface of the image forming / projecting device 7. From this state, if the image forming / projecting device 7 and the temple 9 are rotated in the direction indicated by the arrow, the image forming / projecting device 7 and the temple 9 can be folded while the light emission surface is covered with the shutter plate 13a.

  When the shutter plate 13a is rotated from the state shown in FIG. 2A to the state shown in FIG. 2C through the state shown in FIG. 2B, the light emission surface is covered with the shutter plate 13a. No state. From this state, the image forming and projecting device 7 can be rotated around the second rotation axis in FIG.

It is a figure which shows the outline | summary of the eyeglass display which is an example of embodiment of this invention. It is a figure which shows the example of the shutter which covers a light beam emission surface.
