The X1-X2 direction and the Y1-Y2 direction are perpendicular to each other, and the XY plane including them is perpendicular to the Z1-Z2 direction. Further, a state in which the lower side (Z2 side) is viewed from the upper side (Z1 side) may be referred to as a plan view.

As shown in FIGS. 1 to 4, the image display device 10 according to the present embodiment is equipped with a wearing tool 20 that is worn on the head of a subject and a projection that is held by the wearing tool 20 via an angle adjusting mechanism 30. And a unit 40.
The mounting tool 20 is formed by bending a metal plate material having elasticity. The wearing tool 20 has an elliptical shape in plan view so that the wearing tool 20 can be worn along substantially the entire circumference of the side of the head of the subject, and the elliptical shape can be opened and closed by its elasticity. In the state where it is attached to, the position is held by the elastic force that tries to close the elliptical shape. Since the mounting tool 20 is formed by bending a metal, it is possible to easily select a material and to manufacture the mounting tool 20 at low cost. The metal used for the wearing tool 20 is preferably one having elasticity capable of maintaining a tightening force that does not cause discomfort to the subject while the projection unit 40 is securely held, and examples thereof include titanium.

Output to. As a result, data for generating an image is transmitted from the portable electronic device 104 to the projection unit 40 via the electronic device 102. Here, FIG. 10 is a functional block diagram of the image display device 10.
Further, the power source 102b supplies power to the portable electronic device 104. The image display device 10 is supplied with power from the electronic device 102 through the cord 101, but may be equipped with a power source (not shown) inside. Also, instead of the electronic device 102, an HDMI receiver may be provided in the image display device 10.

As shown in FIGS. 1 to 4, the cord 101 is routed so as to be locked in the holding portion 21 provided by bending in the middle of the wearing tool 20, and is attached to the wearing tool 20 during the routing. It is locked to a plurality of hook portions 22 provided. As a result, the cord 101 is arranged so as to extend along the wearing tool 20, so that the wearing state of the wearing tool 20 is not disturbed, and there is no hindrance to image display or the operation of the subject. Further, the tip of the code 101 is inserted into the introduction hole 43 provided in the main body 41 of the projection unit 40, and is connected to the image generating unit 44 (see FIG. 10) including a plurality of integrated circuits arranged in the main body 41. To be electrically connected.

As shown in FIG. 4, the angle adjusting mechanism 30 includes a support member 31 fixed to the wearing tool 20 and a long plate member 32 supported by the support member 31 via a shaft member 33. The member 33 is swingable up and down (up and down in FIGS. 1 to 4). The support member 31 and the long plate member 32 are formed of a material having hardness such that the position of the projection unit 40 can be maintained, for example, metal or plastic. A coupling hole portion 34 used for coupling with a coupling portion 42 provided in the main body portion 41 of the projection unit 40 penetrates in the left-right direction at the tip end portion of the shaft member 33, that is, the end portion at a position far from the mounting tool 20. It is provided to do. By coupling the long plate member 32 and the projection unit 40 to each other through the coupling hole 34, the angle of the projection unit 40 with respect to the mounting tool 20 can be changed up and down. Therefore, by using the angle adjusting mechanism 30, when the wearing tool 20 is worn on the head, the projection unit 40 is placed at the eye level of the target person, and the projection unit 40 is placed at a position higher than the eyes. The arrangement state can be arbitrarily selected. Here, as the position higher than the eyes, it is possible to select an arbitrary plurality of positions according to the angle of the long plate member 32.

The nose pad 36 is provided at the lower end of the linear support 35 whose upper end is fixed to the wearing tool 20, and has a bifurcated shape on the left and right. The support portion 35 has a curved shape that is directed rearward (toward the target person who wears the wearing device 20) toward the lower end side. The support portion 35 and the nose pad portion 36 are made of a deformable material having elasticity, for example, metal or plastic, and may be integrally formed or separately formed. Due to its elasticity, the support portion 35 brings the nose pad portion 36 into contact with the nose of the target person with an appropriate pressure in the front-rear direction. The elasticity of the nose pad 36 deforms according to the shape of the nose. As a result, the nose pad 36 surely fits the nose with an appropriate pressure, and thus the position of the wearing tool 20 is easily held. As shown in FIG. 2, the support portion 35 and the nose pad portion 36 are sufficient so that the support portion 35 and the nose pad portion 36 do not interfere with the eyeglasses 100 so that the support portion 35 and the nose pad portion 36 can be used even when the eyeglasses 100 are worn.

As shown in FIG. 5 or 6, the projection unit 40 includes a main body 41 having an image generation unit 44 built therein, and a pair of projections 50a and 50b arranged so as to sandwich the main body 41 in the left-right direction. .. The coupling portion 42 is provided on the rear portion of the cover 41a that covers the outer circumference of the main body portion 41. The coupling portion 42 is provided with a through hole 42a penetrating along the left-right direction (X1-X2 direction), and the projection is performed by inserting a pin into the through hole 42a and the coupling hole portion 34 of the angle adjusting mechanism 30. The unit 40 can swing with respect to the angle adjusting mechanism 30 about the pin, and the angle can be changed up and down.

FIG. 6 shows a state in which the cover 41a is removed, and a plurality of integrated circuits forming the image generating unit 44 are arranged on the upper portion and the front portion of the projection unit 40, respectively. As illustrated in FIG. 10, the image generation unit 44 includes an FPGA 44a (Field-Programmable Gate Array), a ROM 44b (Read Only Memory), and a PLL 44c (Phase Locked Loop).

The FPGA 44a generates an image signal based on the signal from the HDMI receiver 102a. This image signal is generated based on information such as a table stored in the ROM 44b in advance. The generated image signal is output to a pair of organic EL elements 51a and 51b via two LVDSs (Low voltage differential signaling), and these organic EL elements 51a and 51b are output from the portable electronic device 104. Images corresponding to the output signals are displayed. The phases of the signals output to the two organic EL elements 51a and 51b are synchronized according to the synchronization signal sent from the PLL 44c to the FPGA 44a.

The pair of organic EL elements 51a and 51b are arranged in the pair of projection units 50a and 50b, respectively. The members of these projection units 50a and 50b and the arrangement order/positions thereof are symmetrical with respect to the main body unit 41. For example, cover members 55a and 55b are arranged on the rear side, and housings 53a and 53b containing prisms are arranged on the front side thereof. Here, only the first projection unit 50a on the right side (X2 side) will be described, but the second projection unit 50b on the left side (X1 side) also has the same symmetrical structure.

7 and 8 are exploded perspective views of the first projection unit 50a, in which the viewing angle is changed. FIG. 9 is a perspective view of the first projection unit 50a.
As shown in FIGS. 7 to 9, the first projection unit 50a includes a housing 53a that encloses the prism 54a. The housing 53a is made of a material that does not transmit light and is waterproof and dustproof, such as plastic, and has openings 56a and 57a on the left side (X1 side) and the rear side (Y2 side), respectively. The fixed frame 52a, the organic EL element 51a, the ring member 70a, and the lid member 64a are arranged in the first opening portion 56a on the left side, and the cover member 55a is arranged in the second opening portion 57a on the rear side. R.

In the first organic EL element 51a, the outer peripheral edge of the display range is fixed to the fixed frame 52a, and the fixed frame 52a is fixed to the first opening 56a of the housing 53a. It is fixed to the housing 53a. Further, a lid member 64a is arranged so as to cover the back surface (left surface) of the first organic EL element 51a. A plate-shaped first adjustment member 65a extends in the left-right direction from the back surface (left surface) of the lid member 64a. As shown in FIG. 9, the ring member 70a is arranged so as to cover the outer peripheral surface of the fixed frame 52a, the first organic EL element 51a, and the lid member 64a from the first opening 56a of the housing 53a. .. Since the ring material 70a is made of a material having elasticity and water impermeability, for example, rubber, it is possible to prevent water, dust, dust, etc. from entering the covering members. From the viewpoint of fixing strength and the like, it is preferable to use an X ring having an X-shaped cross section as the ring material 70a.

Light (image light) corresponding to the image generated by the first organic EL element 51a travels from the first opening 56a into the housing 53a, is refracted by the prism 54a arranged in the housing 53a, The light is emitted from the second opening 57a. If the incident light from the first opening 56a can be emitted from the second opening 57a, an optical element as a reflecting member other than the prism, for example, a reflecting mirror may be used. Further, a collimating lens or other lens, a light diffusing element, or the like may be used in combination depending on the image resolution of the first organic EL element 51a, the specifications of the prism 54a, the specifications of the image projected on the eye of the subject, and the like. .. Further, if the image light can be given to the first opening 56a, an element other than the organic EL element can be used instead of the organic EL element.

A cover member 55a is provided in the second opening 57a so as to cover it. The cover member 55a is made of a material having high light transmittance and waterproof/dustproof property, for example, plastic. By disposing a ring material similar to the ring material 70a so as to cover the outer peripheral surface of the second opening 57a from the cover member 55a, it is possible to enhance waterproofness/dustproofness. Further, the cover member 55a may have a lens function, and for example, the condensing position of the light emitted from the prism 54a can be adjusted.

The first projection unit 50a having the above-described configuration and the second projection unit 50b having a configuration symmetrical to the first projection unit 50a are provided at the left and right ends of the frame unit 45, as shown in FIGS. 6, 12, and 13. Are respectively coupled to. A space adjusting unit 60, which will be described later, is accommodated in the frame unit 45. The space adjusting unit 60 has an upper side and a front side covered with a substrate on which the image generating unit 44 is mounted, and further has an outer side covered with a cover 41a. There is. As a result, the projection unit 40 and the pair of projection parts 50a and 50b on the left and right sides of the projection unit 40 have a sealed structure that prevents water, dust, dust, and the like from entering the inside. Further, since the pair of elastic ring members 70a and 70b are arranged so as to cover the joints between the projection unit 40 and the pair of projection portions 50a and 50b, respectively, the left and right projection portions 50a are arranged. It is possible to prevent water, dust, dust, and the like from entering the inside even when the interval of 50b is changed.

The image generated by the first organic EL element 51a is from the first projection unit 50a, and the image generated by the second organic EL element 51b is from the second projection unit 50b. The subject can observe the images projected by both eyes and displayed by these projections.
Here, since the images projected from the two projection units 50a and 50b have only to reach a predetermined range of the retina of the subject's eye, the projection units 50a and 50b have a size corresponding to this. However, it is not necessary to have a large size that completely covers the visual field of the eye. Since the projection units 50a and 50b are miniaturized in this way, it is possible to visually recognize an external scene from both ends even when the image display device 10 is placed in front of the eyes.

FIG. 11 is an exploded perspective view showing a portion of the space adjusting unit 60 in the projection unit 40. FIG. 12 is an exploded perspective view of the space adjusting unit 60. As shown in FIG. 11 and FIG. 12, the space adjusting unit 60 includes two adjusting members 65a and 65b, an intermediate member 63 arranged between a pair of adjusting members 65a and 65b in the vertical direction, an intermediate member 63, and A pair of guide members 61 and 62 sandwiching the pair of adjusting members 65a and 65b from above and below are provided.

The first adjusting member 65a extends from the lid member 64a provided on the first projection unit 50a on the right side toward the second projection unit 50b on the left side along the left-right direction. The second adjusting member 65b extends substantially symmetrically to the first adjusting member 65a from the lid member 64b provided on the second projection unit 50b along the left-right direction toward the first projection unit 50a side. These adjusting members 65a and 65b are provided with elongated holes 165a and 165b penetrating in the thickness direction (vertical direction) thereof, respectively. These elongated holes 165a and 165b are provided so as to extend in the left-right direction, that is, along the arrangement direction of the pair of projection units 50a and 50b.

The second adjusting member 65b is arranged above the first adjusting member 65a, and the intermediate member 63 is arranged between the pair of adjusting members 65a and 65b in the vertical direction. The lower surface of the intermediate member 63 is provided with a second protruding portion 63a (regulating portion) extending downward. The second protrusion 63a is provided at a position corresponding to the elongated hole 165a of the first adjusting member 65a.

A guide recess 62a having a width corresponding to the width (length in the front-rear direction) of the second adjusting member 65b is provided on the lower surface of the second guide member 62 arranged above the second adjusting member 65b. The concave portion 62a is provided with a first protrusion 62b (regulating portion) extending downward. The first protrusion 62b is provided at a position to be inserted into the elongated hole 165b when the second adjusting member 65b is accommodated in the guide recess 62a.

A guide recess 61a having a width corresponding to the width (length in the front-rear direction) of the first adjusting member 65a is provided on the upper surface of the first guide member 61 arranged below the first adjusting member 65a. .. The second protrusion 63a of the intermediate member 63 is provided at a position to be inserted into the elongated hole 165a of the first guide member 61 when the first adjustment member 65a is accommodated in the guide recess 61a.

The pair of guide members 61, 62 and the intermediate member 63 are fixed to the frame portion 45 with the pair of adjusting members 65a, 65b interposed therebetween. At this time, the second adjusting member 65b is slidably movable in the left and right direction within the guide recess 62a of the second guide member 62, and the first adjusting member 65a is slidably movable in the left and right direction within the guide recess 61a. .. Therefore, the user (target person) of the image display device can independently move the two projection units 50a and 50b along the left-right direction, and the two projection units 50a and 50b can be moved to positions corresponding to the distance between their eyes. Since the projection units 50a and 50b can be arranged respectively, a high quality image can be observed.

13 is a plan view showing a state in which the left and right projection units 50a and 50b are closest to each other, and FIG. 14 is a plan view showing a state in which the left and right projection units 50a and 50b are farthest from each other.
The first protrusion 62b is inserted into the elongated hole 165b of the second adjusting member 65b. Therefore, the lateral displacement of the second adjusting member 65b is restricted to a predetermined range by the first protrusion 62b. Similarly, since the second protrusion 63a is inserted into the elongated hole 165a of the first adjusting member 65a, the lateral displacement of the first adjusting member 65a is restricted to a predetermined range by the second protrusion 63a. .. With these, in a predetermined range between the state where the two projection units 50a and 50b are closest to each other as shown in FIG. 13 and the state where the two projection units 50a and 50b are farthest apart from each other as shown in FIG. The two projection parts 50a and 50b can be displaced. In the state shown in FIG. 13, the first protrusion 62b abuts on the leftmost inner surface of the elongated hole 165b of the second adjusting member 65b, and the second protrusion 63a is the elongated hole of the first adjusting member 65a. It is in contact with the rightmost inner surface of 165a. In the state shown in FIG. 14, the first protrusion 62b abuts on the rightmost inner surface of the elongated hole 165b of the second adjusting member 65b, and the second protrusion 63a is the elongated hole of the first adjusting member 65a. It is in contact with the innermost surface of the leftmost side of 165a.
Note that the two projection units 50a and 50b may be in a displacement state between these two states.

If the pair of adjusting members 65a and 65b can be guided in the left-right direction, a configuration other than the above-described configuration, for example, a configuration in which a guide groove is provided in the intermediate member 63, is also possible. Further, as long as the displacement of the pair of adjusting members 65a and 65b can be regulated, a configuration other than the above-described configuration, for example, a protrusion as a regulating portion may be provided in the guide recess 61a or on the upper surface of the intermediate member 63.

With the above configuration, the following effects are achieved according to the above embodiment.
(1) Since the projection unit 40 is held by the mounting tool 20 via the angle adjusting mechanism 30, the projection unit 40 is swung up and down after the image display device 10 is mounted on the head of the user who is the target. Can be made This makes it possible to arrange the projection unit 40 at a position where the user can easily see it. For example, when only the image of the image display device 10 is desired, it is arranged in front of the eye, and only the image of the image display device 10 is arranged. Alternatively, when it is desired to secure a sufficient peripheral visibility, the projection unit 40 is arranged above the eyes. Further, since the distance from the eye of the user changes depending on the vertical position of the projection unit 40, the projection unit 40 can be moved up and down to a position that matches the visual acuity of the user. Since the projection unit 40 is small in size as a whole, the outside scene can be visually recognized from both end sides even when the projection unit 40 is mounted, and the projection unit 40 visually recognizes the mounted image. You can check.

Since the guide members 61 and 62 for guiding along the displaceable side are arranged, the user can easily displace the pair of projection units 50a and 50b to desired positions.

(4) Since the two protrusions 62b and 63a are provided as the restricting portions that restrict the displacement of the pair of adjusting members 65a and 65b within the predetermined range, the range of displacement of the pair of projection portions 50a and 50b can be limited. As a result, it becomes easy to ensure the waterproof/dustproof property of the connection portion between the projection units 50a and 50b and the main body unit 41, and it is possible to prevent the defect that the projection units 50a and 50b come off from the main unit unit 41.

(5) The image generated by the image generation unit 44 is generated on the pair of organic EL elements 51a and 51b. Since the organic EL element can be formed thin, it contributes to downsizing and weight saving of the projection sections 50a and 50b.

(6) Since the mounting tool 20 is formed by bending a metal, the manufacturing cost can be suppressed.

(7) By providing the nose pad 36 on the wearing device 20, it can be worn with an appropriate pressure regardless of the shape of the nose of the user. The support portion 35 and the nose pad portion 36 are configured to have a sufficient length so that the support portion 35 and the nose pad portion 36 do not interfere with the eyeglasses 100 so that the support portion 35 and the nose pad portion 36 can be used even when the eyeglasses 100 are worn. ..
