  As shown in FIGS. 3 and 4, the first three-dimensional image display unit 10 includes three light sources 12A, 12B, and 12C, and a light guide plate 15.

  The light sources 12A, 12B, and 12C are, for example, light emitting diode (LED) light sources. The light sources 12A, 12B, and 12C are arranged side by side in the Z-axis direction.

  The light guide plate 15 is a member for guiding the light (incident light) incident from the light sources 12A, 12B and 12C. The light guide plate 15 is formed of a transparent resin material having a relatively high refractive index. As a material for forming the light guide plate 15, for example, polycarbonate resin, polymethyl methacrylate resin or the like can be used.

As shown in FIG. 4, the light guide plate 15 includes an emission surface 15 a (light emission surface), a back surface 15 b, and an incident surface 15 c.

  The emission surface 15 a is a surface which is guided in the light guide plate 15 and emits the light whose optical path has been changed by the optical path changing unit 16 described later. The exit surface 15 a constitutes the front surface of the light guide plate 15. The back surface 15b is a surface parallel to the emission surface 15a, and is a surface on which an optical path changing unit 16 described later is disposed. The incident surface 15c is a surface on which the light emitted from the light sources 12A, 12B, and 12C enters the inside of the light guide plate 15. The light emitted from the light sources 12A, 12B and 12C and incident on the light guide plate 15 from the incident surface 15c is totally reflected by the output surface 15a or the back surface 15b and guided in the light guide plate 15.

  As shown in FIG. 4, the optical path changing unit 16 is formed on the back surface 15 b inside the light guide plate 15 and is for changing the optical path of the light guided in the light guide plate 15 and emitting the light from the emission surface 15 a. It is a member. A plurality of optical path changing units 16 are provided on the back surface 15 b of the light guide plate 15.

  The optical path changing unit 16 is provided along a direction parallel to the incident surface 15c, as shown in FIG. As shown in FIG. 6, the optical path changing unit 16 has a triangular pyramid shape, and includes a reflecting surface 16 a that reflects (totally reflects) incident light. The optical path changing unit 16 may be, for example, a recess formed on the back surface 15 b of the light guide plate 15. The optical path changing unit 16 is not limited to the triangular pyramid shape. On the back surface 15b of the light guide plate 15, as shown in FIG. 5, a plurality of optical path changing portion groups 17a, 17b, 17c... Consisting of a plurality of optical path changing portions 16 are formed.

As shown in FIG. 7, in each of the optical path changing portion groups 17a, 17b, 17c, ..., the reflecting surfaces 16a of the plurality of optical path changing portions 16 are disposed on the back surface 15b of the light guide plate 15 so that the angles with respect to the incident direction It is done. As a result, each of the optical path changing portion groups 17a, 17b, 17c,...

  Next, a method of forming a stereoscopic image by the first stereoscopic image display unit 10 will be described with reference to FIG. Here, the case where a three-dimensional image as a plane image is formed by the light whose optical path has been changed by the light path changing unit 16 on the three-dimensional image forming plane P which is a plane perpendicular to the exit surface 15a of the light guide plate 15 will be described. In addition, here, a case where a stereoscopic image is formed by the light emitted from the light source 12A among the light sources 12A, 12B, and 12C will be described.

  FIG. 8 is a perspective view showing a method of forming a stereoscopic image I by the first stereoscopic image display unit 10. Here, the formation of an oblique line ring mark as a stereoscopic image I on the stereoscopic image imaging plane P will be described.

  In the first three-dimensional image display unit 10, as shown in FIG. 8, for example, the light whose optical path is changed by each optical path changing unit 16 of the optical path changing unit group 17a is a line La1 and a line La2 on the three-dimensional image forming plane P. Cross. Thereby, the line image LI which is a part of the stereoscopic image I is formed on the stereoscopic image imaging plane P. The line image LI is a line image parallel to the YZ plane. As described above, the line images LI of the line La1 and the line La2 are formed by the light from the large number of optical path changing units 16 belonging to the optical path changing unit group 17a. The light for forming the images of the line La1 and the line La2 may be provided by at least two light path changing units 16 in the light path changing unit group 17a.

  Similarly, the light whose optical path is changed by each optical path changing unit 16 of the optical path changing unit group 17b intersects the stereoscopic image imaging plane P at a line Lb1, a line Lb2, and a line Lb3. Thereby, the line image LI which is a part of the stereoscopic image I is formed on the stereoscopic image imaging plane P.

  Further, the light whose optical path is changed by each optical path changing unit 16 of the optical path changing unit group 17c intersects the stereoscopic image imaging plane P at a line Lc1 and a line Lc2. Thereby, the line image LI which is a part of the stereoscopic image I is formed on the stereoscopic image imaging plane P.

  The positions in the X-axis direction of line images LI formed by the respective optical path changing portion groups 17a, 17b, 17c... Are different from each other. In the first three-dimensional image display unit 10, the X-axis of the line image LI formed by each of the optical path changing unit groups 17a, 17b, 17c, ... by reducing the distance between the optical path changing unit groups 17a, 17b, 17c. The distance of the direction can be reduced. As a result, in the first three-dimensional image display unit 10, a plurality of line images LI formed by the light path changed by the light path change units 16 of the light path change unit groups 17a, 17b, 17c. A stereoscopic image I, which is a planar image, is substantially formed on the stereoscopic image imaging plane P.

  The three-dimensional image imaging surface P may be a plane perpendicular to the X axis, a plane perpendicular to the Y axis, or a plane perpendicular to the Z axis. Further, the stereoscopic image imaging plane P may be a plane not perpendicular to the X axis, the Y axis, or the Z axis. Furthermore, the stereoscopic image imaging surface P may be a curved surface instead of a flat surface. That is, the first three-dimensional image display unit 10 can cause the light path changing unit 16 to form a three-dimensional image I on an arbitrary surface (plane and curved surface) in space. Further, by combining a plurality of plane images, a three-dimensional image can be formed.

  Further, although the imaging of the ring mark with oblique lines as the stereoscopic image I has been described here, the arrangement of the optical path changing portion 16 in the optical path changing portion groups 17a, 17b, 17c. A stereoscopic image can be displayed.

  The first three-dimensional image display unit 10 is installed on the front of the housing 2. The light guide plate 15 of the first three-dimensional image display unit 10 is installed such that the back surface 15b is in contact with the front surface of the housing 2 and the emission surface 15a is the front surface.

  The second stereoscopic image display unit 20 is installed on the top surface of the housing 2. The configuration of the second three-dimensional image display unit 20 is the same as the configuration of the first three-dimensional image display unit 10, and therefore the description thereof is omitted. However, in the light guide plate 15 of the second three-dimensional image display unit 20, the surface facing the incident surface 15c contacts the upper surface of the housing 2 and the forward direction (+ X) as the output surface 15a goes upward (+ Y direction) Direction) is installed. The light guide plate 15 of the second three-dimensional image display unit 20 is disposed such that the incident surface 15c is parallel to the XZ plane. Thus, the light sources 12A, 12B, and 12C of the second three-dimensional image display unit 20 are arranged in the Z-axis direction. As described above, by installing the light guide plate 15 of the second three-dimensional image display unit 20, the air blown out from the blowout port 2a can be directed forward.

3 3 Operation Example Next, an operation example (the following operation example 1 and operation example 2) of the air cleaner 1 will be described.

<Operation example 1>
In the air purifier 1, when the gas sensor 3 is in operation, the control unit 30 causes the first stereoscopic image display unit 10 to display the stereoscopic image I1. FIG. 10 is a diagram showing a state in which the stereoscopic image I1 is displayed by the first stereoscopic image display unit 10. As shown in FIG. In the first three-dimensional image display unit 10 of the present embodiment, as shown in FIG. 10, the optical path changing group 17a, 17b, and 17b are formed so that a triangle is formed as the three-dimensional image I1 on the back surface 15b of the light guide plate 15. Each optical path changing part 16 of 17c ... is formed.

  The control unit 30 sequentially turns on the light sources 12A, 12B, and 12C of the first three-dimensional image display unit 10 when the gas sensor 3 is operating. As described above, the light sources 12A, 12B, and 12C are disposed at different positions in the Z-axis direction. Therefore, in the stereoscopic images I1A, I1B, I1C as the stereoscopic image I1 formed by the light emitted from the light sources 12A, 12B, 12C, the positions where the images are formed are different in the Z-axis direction. Specifically, as shown in FIG. 10, for example, when the light source 12A is on, the stereoscopic image I1A is formed as the stereoscopic image I1. In FIG. 10, for convenience of explanation, all of the stereoscopic images I1A, I1B, and I1C are illustrated, but in actuality, only one stereoscopic image of the stereoscopic images I1A, I1B, and I1C is formed. Similarly, when the light sources 12B and 12C are on, stereoscopic images I1B and I1C are formed respectively. In the first three-dimensional image display unit 10, the three-dimensional image I1 (that is, the three-dimensional images I1A, I1B, I1C) is configured to form an image in a sensing target space where the gas sensor 3 detects the state of the surrounding air. .

  According to the above configuration, in the air cleaner 1, the light source 12A, 12B, 12C of the first three-dimensional image display unit 10 is turned on in order to display the triangle as moving (that is, display an animation) be able to. As a result, it is possible to display the state in which the gas sensor 3 is sensing as a stereoscopic image. As a result, the air purifier 1 can intuitively recognize that the gas sensor 3 is sensing.

<Operation example 2>
In the air cleaner 1, when the ion generator 5 is operated to blow out the air, the control unit 30 causes the second stereoscopic image display unit 20 to display the stereoscopic image I2. As shown in FIG. 1, in the second stereoscopic image display unit 20 of the present embodiment, a stereoscopic image I2 having a plurality of circular stereoscopic images as a stereoscopic image I2 is formed on the back surface 15b of the light guide plate 15. Each optical path changing portion 16 of the optical path changing portion groups 17a, 17b, 17c,... Is formed. In the second three-dimensional image display unit 20, the three-dimensional image I2 is configured to form an image in a blowout space from which the air is blown out from the blowout port 2a.

  The control unit 30 sequentially turns on the light sources 12A, 12B, and 12C of the second three-dimensional image display unit 20 when operating the ion generator 5 to blow out the air. As described above, the light sources 12A, 12B, and 12C are disposed at different positions in the Z-axis direction. Therefore, similar to the stereoscopic image I1 in the operation 1, the plurality of circular stereoscopic images can be displayed (that is, displayed in animation) as if they are moving. As a result, it is possible to display the state in which the ions are blown out from the air cleaner 1 as a stereoscopic image. Thereby, the air cleaner 1 can intuitively recognize to the user that the ions are blown out of the air cleaner 1.

  As described above, in the air cleaner 1, the user can intuitively recognize that the gas sensor 3 is sensing by the three-dimensional image I1 formed by the first three-dimensional image display unit 10. Further, in the air cleaner 1 of the present embodiment, the user intuitively recognizes that the air is blown out from the blowout port 2a by the stereoscopic image I2 formed by the second stereoscopic image display unit 20. Can. That is, the air purifier 1 can make the user intuitively recognize the operation state of the air purifier 1 by a stereoscopic image.

  Further, since the light guide plate 15 of the first three-dimensional image display unit 10 and the second three-dimensional image display unit 20 is made of a transparent member, the first three-dimensional image display unit 10 and the second three-dimensional image display unit 20 can be The stereoscopic image display unit 10 and the second stereoscopic image display unit 20 can be installed in the housing 2.

  In the present embodiment, the air cleaner 1 is configured to include both the first stereoscopic image display unit 10 and the second stereoscopic image display unit 20, but the air cleaner according to the present disclosure is not limited to this. . The air purifier according to one aspect of the present disclosure may include at least one of the first stereoscopic image display unit 10 and the second stereoscopic image display unit 20.

  In addition, the air cleaner according to one aspect of the present disclosure may be configured to include other sensors (for example, a dust collection sensor, a human sensor, and the like) other than the gas sensor 3. Then, the first stereoscopic image display unit 10 may display a stereoscopic image indicating that the other sensor is sensing in the sensing target space where the other sensor senses the surrounding state. Moreover, in the air cleaner of one aspect of the present disclosure, a three-dimensional image display unit other than the first three-dimensional image display unit and the second three-dimensional image display unit is provided, and a three-dimensional image indicating that the other sensor is sensing The image may be formed by the third stereoscopic image display unit.

  Further, in the air purifier according to one aspect of the present disclosure, when displaying the stereoscopic image I1 by the first stereoscopic image display unit 10, the control unit 30 lights up one light source (for example, the light source 12B). At the same time, the light source lighted immediately before (for example, the light source 12A) may be lighted at a smaller luminance than the light source 12B. As a result, the stereoscopic image I1B imaged by the light source 12B is imaged at high luminance, and the imaging is performed by the light source 12A and the stereoscopic image I1A is imaged at low luminance. By repeating such an operation and turning on the light sources 12A, 12B, and 12C in order, an afterimage can be given to the stereoscopic image I1. As a result, the user can intuitively recognize that the gas sensor 3 is sensing.

  In the present embodiment, the second stereoscopic image display unit 20 is configured to form the stereoscopic image I2 having a plurality of circular stereoscopic images, but the air cleaner of the present disclosure is not limited to this. . In the air cleaner according to one aspect of the present disclosure, the second stereoscopic image display unit 20 may form an image of a logo (mark) that is associated with the ion generator 5. For example, in the case where the ion generator 5 is generally widely known and the logo indicating the ion generator 5 is generally widely known, imaging the above logo as a stereoscopic image I2 Thus, the user can be made aware that the ions are being blown out.

  FIG. 9 is a view showing the upper portion of the air cleaner 1 of the air cleaner 1 according to an aspect of the present disclosure. As shown in FIG. 9, in the air cleaner 1 of the present embodiment, a stereoscopic image display unit 40 different from the second stereoscopic image display unit 20 is used to display the logo 41 separately from the plurality of circular stereoscopic images I2. Is provided on the top surface of the housing 2. The three-dimensional image display unit 40 is provided so as to overlap the housing 2 such that the emission surface 15 a of the light guide plate 15 is an upper surface. The stereoscopic image display unit 40 may display the logo 41 so that the color of the logo 41 changes by making the wavelengths of the light emitted from the light sources 12A, 12B, and 12C different from each other. In addition, the stereoscopic image display unit 40 may display the logo 41 so as to shake.

  In addition, the device in the present disclosure does not necessarily have to display a stereoscopic image in animation. For example, the first stereoscopic image display unit 10 may be configured to include only the light source 12A as a light source. Then, when the gas sensor 3 is in operation, the control unit 30 is configured to turn on the light sources 12A, 12B, and 12C to display only the stereoscopic image I1A (that is, display a still image as the stereoscopic image I1). It is also good.

  In addition, the air cleaner 1 of the present embodiment includes the ion generator 5 and connects the stereoscopic image I2 having a plurality of circular stereoscopic images representing the ions generated by the second stereoscopic image display unit 20 by the ion generator 5. Although the configuration is an image, the device of the present disclosure is not limited to this. The device according to the present disclosure does not need to include the ion generator 5 and may be a device having a blowout part from which a gas is blown out and blowing out any gas from the blowout part. Then, the second stereoscopic image display unit 20 may be configured to display a stereoscopic image indicating that the gas is blown out from the blowout portion into the blowout space from which the gas is blown out from the blowout portion.

  Moreover, although the air cleaner 1 as an apparatus of this indication was demonstrated in this embodiment, the apparatus of this indication is not restricted to this.

  Further, the device according to one aspect of the present invention displays the stereoscopic image I as a fusion image by using the light emitted from the transparent light guide plate as the first stereoscopic image display unit 10 and the second stereoscopic image display unit 20 A stereoscopic image display unit can also be used.

4 4 Modifications Although the embodiments of the present invention have been described in detail, the above description is merely illustrative of the present invention in all respects. It goes without saying that various improvements and modifications can be made without departing from the scope of the present invention. For example, the following changes are possible. In the following, the same reference numerals are used for the same constituent elements as the above embodiment, and the description of the same parts as the above embodiment is appropriately omitted. The following modifications may be combined as appropriate.

<4.1>
The configurations of the first stereoscopic image display unit 10 and the second stereoscopic image display unit 20 in the device of the present disclosure are not limited to those described in the first embodiment. In this modification, a stereoscopic image display unit 50 as a modification of the first stereoscopic image display unit 10 and the second stereoscopic image display unit 20 in the first embodiment will be described.

  FIG. 11 is a perspective view of the stereoscopic image display unit 50. FIG. In FIG. 11, the stereoscopic image display unit 50 displays the stereoscopic image I, more specifically, a button shape (shape projecting in the + X axis direction) in which the character “ON” is displayed. Showing how As shown in FIG. 11, the stereoscopic image display unit 50 includes a light guide plate 51 and a light source 52.

  The light guide plate 51 has a rectangular parallelepiped shape, and is formed of a resin material having transparency and a relatively high refractive index. The material forming the light guide plate 51 may be, for example, polycarbonate resin, polymethyl methacrylate resin, glass or the like. The light guide plate 51 includes an emission surface 51a for emitting light, a back surface 51b opposite to the emission surface 51a, and an end surface 51c, an end surface 51d, an end surface 51e and an end surface 51f which are four end surfaces. The end surface 51 c is an incident surface on which the light projected from the light source 52 is incident on the light guide plate 51. The end face 51d is a face on the opposite side to the end face 51c. The end face 51e is a face opposite to the end face 51f. The light guide plate 51 spreads and guides the light from the light source 52 on the surface in a plane parallel to the emission surface 51a. The light source 52 is, for example, a light emitting diode (LED) light source.

  On the back surface 51b of the light guide plate 51, a plurality of optical path changing units 53 including an optical path changing unit 53a, an optical path changing unit 53b, and an optical path changing unit 53c are formed. The optical path changing portion 53 is formed substantially continuously in the Z-axis direction. In other words, the plurality of optical path changing units 53 are formed along predetermined lines in a plane parallel to the emission surface 51a. Specifically, as shown in FIG. 11, the optical path changing unit 53a, the optical path changing unit 53b, and the optical path changing unit 53c are formed along the line La, the line Lb, and the line Lc. Here, the line La, the line Lb and the line Lc are straight lines substantially parallel to the Z-axis direction. The optional optical path changing portion 53 is formed substantially continuously along a straight line parallel to the Z-axis direction.

  The light projected from the light source 52 and guided by the light guide plate 51 is incident on each position in the Z-axis direction of the optical path changing unit 53. The optical path changing unit 53 substantially converges the light incident on each position of the optical path changing unit 53 to a fixed point corresponding to each optical path changing unit 53. In FIG. 11, the optical path changing portion 53a, the optical path changing portion 53b, and the optical path changing portion 53c are particularly shown as a part of the optical path changing portion 53, and the optical path changing portion 53a, the optical path changing portion 53b, and the optical path changing portion 53c. In each of them, a state is shown in which a plurality of lights emitted from each of the optical path changing unit 53a, the optical path changing unit 53b, and the optical path changing unit 53c converge.

  Specifically, the optical path changing unit 53a corresponds to the fixed point PA of the stereoscopic image I. The light from each position of the optical path changing unit 53a converges to the fixed point PA. Therefore, the wave front of the light from the optical path changing unit 53a becomes the wave front of the light emitted from the fixed point PA. The optical path changing unit 53 b corresponds to the fixed point PB on the stereoscopic image I. The light from each position of the optical path changing unit 53b converges to the fixed point PB. As described above, the light from each position of an arbitrary light path changing unit 53 substantially converges to a fixed point corresponding to each light path changing unit 53. Thereby, an arbitrary light path changing unit 53 can provide a wavefront of light from which light is emitted from the corresponding fixed point. The fixed points corresponding to the respective optical path changing units 53 are different from each other, and the collection of a plurality of fixed points respectively corresponding to the optical path changing units 53 makes the user in space (more specifically, on the space from the light guide plate 51 to the emission surface 51a side) A stereoscopic image I recognized by the image is formed.

  The device according to one aspect of the present disclosure may be configured to include the stereoscopic image display unit 50 described in the present variation instead of the first stereoscopic image display unit 10 and the second stereoscopic image display unit 20 in the first embodiment. Good.

<4.2>
In this modification, a stereoscopic image display unit 80 as a further modification of the first stereoscopic image display unit 10 and the second stereoscopic image display unit 20 in the first embodiment will be described.

  FIG. 12 is a perspective view of the stereoscopic image display unit 80. As shown in FIG. FIG. 13 is a cross-sectional view showing the configuration of the stereoscopic image display unit 80. As shown in FIG.

  As shown in FIGS. 12 and 13, the stereoscopic image display unit 80 includes an image display device 81, an imaging lens 82, a collimator lens 83, a light guide plate 84, and a mask 85. The image display device 81, the imaging lens 82, the collimator lens 83, and the light guide plate 84 are disposed in order along the Y-axis direction. Further, the light guide plate 84 and the mask 85 are arranged in this order along the X-axis direction.

  The image display device 81 displays a two-dimensional image projected on the air by the stereoscopic image display unit 80 in the display area according to the video signal received from the control device (not shown). The image display device 81 is, for example, a general liquid crystal display that can output image light by displaying an image in a display area. In the illustrated example, the display area of the image display device 81 and the incident surface 84 a of the light guide plate 84 facing the display area are both arranged parallel to the YZ plane. In addition, a back surface 84b of the light guide plate 84 on which a prism 141 described later is disposed, and an exit surface 84c (light exit surface) that emits light to the mask 85 facing the back surface 84b are both XY planes. It is arranged to be parallel. Furthermore, the surface of the mask 85 on which the slits 151 described later are provided is also arranged in parallel to the XY plane. Note that the display area of the image display device 81 and the incident surface 84a of the light guide plate 84 may be disposed to face each other, or even if the display region of the image display device 81 is inclined to the incident surface 84a. Good.

  The imaging lens 82 is disposed between the image display device 81 and the incident surface 84 a. The imaging lens 82 converges the image light output from the display area of the image display device 81 in the XY plane parallel to the longitudinal direction of the incident surface 84 a and then emits the light to the collimating lens 83. The imaging lens 82 may be anything as long as it can converge image light. For example, the imaging lens 82 may be a bulk lens, a Fresnel lens, or a diffractive lens. Further, the imaging lens 82 may be a combination of a plurality of lenses disposed along the Z-axis direction.

  The collimator lens 83 is disposed between the image display device 81 and the incident surface 84 a. The collimator lens 83 collimates the image light converged by the imaging lens 82 in the XY plane orthogonal to the longitudinal direction of the incident surface 84a. The collimating lens 83 emits collimated image light to the incident surface 84 a of the light guide plate 84. The collimating lens 83 may be a bulk lens and a Fresnel lens, as with the imaging lens 82. The arrangement order of the imaging lens 82 and the collimator lens 83 may be reversed. Further, the functions of the imaging lens 82 and the collimator lens 83 may be realized by one lens, or may be realized by a combination of a large number of lenses. That is, if the image light output from the display area by the image display device 81 can be converted into convergent light in the XY plane and collimated in the YZ plane, the combination of the imaging lens 82 and the collimator lens 83 is It may be anything.

  The light guide plate 84 is made of a transparent member, receives the image light collimated by the collimator lens 83 at the incident surface 84a, and emits the light from the output surface 84c. In the illustrated example, the light guide plate 84 has a flat rectangular outer shape, and a plane parallel to the XZ plane, which faces the collimator lens 83, is used as the incident surface 84a. A surface parallel to the YZ plane and present on the negative direction side of the X axis is a back surface 84b, and a surface parallel to the YZ plane and facing the back surface 84b is a light exit surface 84c. The light guide plate 84 includes a plurality of prisms (optical path changing units) 141.

  The plurality of prisms 141 reflect the image light incident from the incident surface 84 a of the light guide plate 84. The prism 141 is provided on the back surface 84 b of the light guide plate 84 so as to protrude from the back surface 84 b toward the emission surface 84 c. For example, when the propagation direction of the image light is the Y-axis direction, the plurality of prisms 141 are disposed at a predetermined interval (for example, 1 mm) in the Y-axis direction, and have a predetermined width (for example, Grooves of approximately 10 μm). The prism 141 includes a reflection surface 141 a which is a surface closer to the light incident surface 84 a with respect to the light guide direction (+ Y axis direction) of the image light among the optical surfaces of the prism 141. In the illustrated example, the plurality of prisms 141 are provided on the back surface 84 b in parallel with the Z axis. Thus, the image light incident from the incident surface 84a propagating in the Y-axis direction is reflected by the reflecting surfaces 141a of the plurality of prisms 141 provided in parallel with the Z-axis orthogonal to the Y-axis. Each of the plurality of prisms 141 directs image light emitted from mutually different positions in the Z-axis direction orthogonal to the longitudinal direction of the incident surface 84 a in the display area of the image display device 81 to the predetermined viewpoint 100 in the light guide plate 84. The light is emitted from the emission surface 84c which is one surface. Details of the reflective surface 141a will be described later.

  The mask 85 is made of a material opaque to visible light, and includes a plurality of slits 151. The mask 85 can transmit only light traveling toward the imaging point 101 on the plane 102 among the light emitted from the emission surface 84 c of the light guide plate 84 using the plurality of slits 151.

  Among the light emitted from the exit surface 84 c of the light guide plate 84, the plurality of slits 151 transmit only the light directed to the imaging point 101 on the plane 102. In the illustrated example, the plurality of slits 151 are provided in parallel with the Z axis. Each slit 151 corresponds to any one of the plurality of prisms 141.

  With the above configuration, the stereoscopic image display unit 80 forms an image displayed on the image display device 81 on a virtual plane 102 outside the stereoscopic image display unit 80 and projects the image. Specifically, first, the image light emitted from the display region of the image display device 81 passes through the imaging lens 82 and the collimator lens 83, and then enters the incident surface 84a, which is the end surface of the light guide plate 84. Next, the image light incident on the light guide plate 84 propagates inside the light guide plate 84 and reaches the prism 141 provided on the back surface 84 b of the light guide plate 84. The image light having reached the prism 141 is reflected by the reflection surface 141a of the prism 141 in the positive direction of the X axis, and is emitted from the emission surface 84c of the light guide plate 84 disposed parallel to the YZ plane. . Then, among the image light emitted from the emission surface 84 c, the image light having passed through the slit 151 of the mask 85 forms an image at the imaging point 101 on the plane 102. That is, image light emitted from individual points in the display area of the image display device 81 is converged on the YZ plane, collimated on the XY plane, and then projected onto the imaging point 101 on the plane 102. Can. By performing the above-described process on all the points in the display area, the stereoscopic image display unit 80 can project the image output to the display area of the image display device 81 onto the plane 102. Thereby, the user can visually recognize the image projected in the air when viewing the virtual plane 102 from the viewpoint 100. Although the plane 102 is a virtual plane on which the projected image is formed, a screen or the like may be arranged to improve the visibility.

  In the stereoscopic image display unit 80 according to the present embodiment, the image light is formed by the image light transmitted through the slit 151 of the mask 85 among the image light emitted from the output surface 84c. However, as long as the image light can be imaged at the imaging point 101 on the virtual plane 102, the configuration may be such that the mask 85 and the slit 151 are not provided.

  For example, image light is formed at the imaging point 101 on the virtual plane 102 by setting the angle between the reflection surface of each prism 141 and the back surface 84b to increase as the distance from the incident surface 84a increases. be able to. The above-mentioned angle is preferably set to be an angle which can totally reflect the light from the image display device 81 even with the prism 141 farthest from the incident surface 84a.

  When the angle is set as described above, the light traveling from the point where the position in the X-axis direction on the display area of the image display device 81 is closer to the back surface 84b (−X-axis direction side) toward the predetermined viewpoint The light is reflected by the prism 141 far from the incident surface 84a. However, the present invention is not limited to this, as long as the position in the X-axis direction on the display area of the image display device 81 corresponds to the prism 141 one to one. Further, the light reflected by the prism 141 farther from the incident surface 84a is directed to the incident surface 84a side, while the light reflected by the prism 141 closer to the incident surface 84a is directed farther from the incident surface 84a. Therefore, even if the mask 85 is omitted, the light from the image display device 81 can be emitted toward a specific viewpoint. Further, the light emitted from the light guide plate 84 forms an image on the plane on which the image is projected in the Z-axis direction, and diffuses as it goes away from the plane. Therefore, since a parallax can be given in the Z-axis direction, the observer can stereoscopically observe the projected image by arranging the both eyes along the Z-axis direction.

  Further, according to the above configuration, since the light reflected by each prism 141 and not directed to the viewpoint is not blocked, even if the observer moves the viewpoint along the Y-axis direction, the image display apparatus The image displayed at 81 and projected in the air can be observed. However, since the angle formed by the light ray going from each prism 141 to the viewpoint and the reflection surface of each prism 141 changes along the position of the viewpoint in the Y-axis direction, the image display device 81 corresponding to that light ray accordingly. The position of the upper point also changes. Further, in this example, light from each point on the image display device 81 is imaged to some extent also in the Y-axis direction by each prism 141. Therefore, the observer can observe a three-dimensional image even if the eyes are aligned along the Y-axis direction.

  Furthermore, according to the above configuration, since the mask 85 is not used, the amount of light to be lost is reduced, so the stereoscopic image display unit can project a brighter image into the air. In addition, since a mask is not used, the stereoscopic image display unit can allow the observer to visually recognize both an object (not shown) behind the light guide plate 84 and the projected image.

In the air cleaner 1 according to the first embodiment, the first three-dimensional image display unit 10 is configured such that the incident surface 15c of the light guide plate 15 of the first three-dimensional image display unit 10 is in the horizontal direction (that is, the direction parallel to the XZ plane). Was installed. As a result, since the light sources 12A, 12B, 12C are arranged side by side in the Z-axis direction, the stereoscopic images I1A, I1B, I1C imaged by the light emitted from the light sources 12A, 12B, 12C are in the Z-axis direction. Images are formed at different positions. Therefore, when the three-dimensional images I1A, I1B, and I1C are displayed by animation, the display moves only in the horizontal direction.

  FIG. 14 is a diagram showing a first three-dimensional image display unit 10 in the present modification. As shown in FIG. 14, the first stereoscopic image display unit 10 in the present modification is installed by rotating the first stereoscopic image display unit 10 in the first embodiment with the X axis as a rotation axis. Thus, the incident surface 15c of the light guide plate 15 is oblique to the horizontal direction. As a result, the light sources 12A, 12B and 12C are arranged in a direction oblique to the horizontal direction. Thereby, the stereoscopic images I1A, I1B, I1C formed by the light emitted from the light sources 12A, 12B, 12C are different not only in the horizontal direction (Z-axis direction) but also in the vertical direction (Y-axis direction) It is imaged at the position. As a result, when an animation is displayed by the stereoscopic images I1A, I1B, and I1C, it is possible to display moving in the horizontal direction and the vertical direction.

  The second three-dimensional image display unit 60 includes a light source 12D and a light source 12E in addition to the configuration of the second three-dimensional image display unit 20 in the first embodiment, as shown in (a) of FIG. In the second stereoscopic image display unit 60, an optical path changing unit is formed such that circular stereoscopic images I2A to I2E are formed as the stereoscopic image I2 when any of the light sources 12A to 12E is turned on.

  Further, in the second stereoscopic image display unit 60, as shown in (b) of FIG. 15, the stereoscopic images I2A, I2B and I2D are imaged as a real image in the space on the exit surface 15a side of the light guide plate 15, and the stereoscopic image I2C. The stereoscopic image I2E is formed as a virtual image in a space on the back surface 15b side of the light guide plate 15.

  When the second stereoscopic image display unit 60 has the above configuration, when the light source 12A → the light source 12B → the light source 12C → the light source 12D → the light source 12E is turned on, the stereoscopic images I2A, I2B and I2D are in the -Z direction. The stereoscopic images I2C and I2E are displayed to move in the + Z direction, while the stereoscopic images I2C and I2E are displayed to move to. In other words, the direction in which the three-dimensional image formed in the space on the light exit surface 15a side of the light guide plate 15 moves and the direction in which the three-dimensional image formed in the space on the back surface 15b side of the light guide plate 15 moves Displayed differently. Thus, the second stereoscopic image display unit 60 can perform display closer to the actual flow of air.
