Description

The present invention relates to a lighting device such as a flashlight, a penlight, a desk light, etc. for brightening or directing in a dark place, and an image display device such as a display, a gaming machine, etc., and a hologram or a holographic stereogram The present invention relates to a device having a function for effectively observing the image and a hologram medium thereof.

The hologram can reproduce a three-dimensional image (hologram image) when the reproduction light is incident thereon. As this reproduction light, coherent light such as laser light may be required. However, when reproducing a so-called rainbow hologram or Lippmann hologram, for example, an incoherent light such as a halogen lamp or natural light is used. A white light source can be used as reproduction light.

As described above, a hologram that can use a white light source as reproduction light has been widely used for the purpose of preventing counterfeiting in a credit card, for example. For example, various hologram display apparatuses are used as apparatuses for displaying hologram images for the purpose of viewing.

When the reproduction light is incident on the hologram, the wavefront of the object light at the time of recording is reproduced, and this wavefront is observed as a hologram image by the observer.

One type of hologram is a so-called holographic stereogram. A holographic stereogram, for example, uses a large number of images obtained by sequentially imaging a subject from different observation points as an original image, and sequentially exposes them as a strip or dot element hologram on a single hologram recording medium. It is made by recording.

For example, as shown in FIG. 12, a holographic stereogram having parallax information only in the horizontal direction includes a plurality of original images 101a to 101e obtained by sequentially photographing the subject 100 from different observation points in the horizontal direction. In the holographic stereogram manufacturing apparatus having the optical system, the interference fringes generated by the interference between the object light and the reference light that are image-modulated by irradiating the displayed image with laser light are strip-shaped. It is manufactured by sequentially exposing and recording on the hologram recording medium 102 as an element hologram.

The holographic stereogram produced in this way has image information obtained by sequentially capturing images from different observation points in the horizontal direction, and is recorded sequentially in the horizontal direction as strip-shaped element holograms. When a person sees this from one position with one eye, a collection of image information recorded as a part of each element hologram is identified as a two-dimensional image, and another position different from this position When viewed with one eye, the collection of image information recorded as the other part of each element hologram is identified as another two-dimensional image. Therefore, when the observer views the holographic stereogram with both eyes, the exposure recording image is recognized as a three-dimensional image by the parallax between the left and right eyes.

By the way, in order to improve the visibility of a hologram image by properly reproducing a hologram such as the holographic stereogram as described above, the divergence angle of light emitted as reproduction light from a light source is referred to at the time of recording the hologram. It is required to be in a state close to light or parallel light. Therefore, when reproducing a hologram, the visibility and image quality of the observed hologram image change according to the spatial positional relationship between the hologram and the light source or the observer, or the physical shape thereof. .

Therefore, particularly when displaying a hologram for the purpose of viewing, it is required to enable good reproduction of the hologram image by limiting the positional relationship between the hologram, the light source, and the observer.

As such a hologram display device, various devices including a hologram and a light source for irradiating the hologram with reproduction light have been proposed as described in, for example, Patent Document 1 below.

Japanese Patent Laid-Open No. 10-063210 JP 2007-249114 A (Pen type viewer) JP 2008-70478 A (Hologram packaging)

There are various proposals for penlights used in concerts.
JP 2009-176697 A (Multi-color penlight)

There are also various proposals for a flashlight function that can be used in the event of a disaster.

In addition, in POP (POINT OF PURCHASE) devices used in game machines such as pachinko and shops, vending machines such as beverages, stereoscopic images, etc. for the purpose of giving a sense of excitement and eye-catching It is required to produce the effect of. For this purpose, the following devices are disclosed.

Japanese Patent Application Laid-Open No. 07-088247 describes that a transparent glass-like display body including a hologram image is illuminated with light so that an image that was not visible can be seen. However, if the background is bright, the hologram image is difficult to see. When illuminating a hologram image, the display of the background display cannot be darkened, and the background display is also illuminated simultaneously by the hologram illumination, so the contrast of the hologram image cannot be increased. It was. Moreover, since it is illumination light glass, there was no flexibility and it was difficult to move display body itself. Furthermore, when the display body is colored, there is a problem that the visibility of the display image is deteriorated.

In Japanese Patent Laid-Open No. 2001-145728 and Japanese Patent No. 4553427, an image projection film for displaying image information by projection light is arranged in combination with a display, and the image projection film and an image reproduction film such as a hologram are combined. An example of joining sheets is disclosed. However, here too, when reproducing the hologram image, there has been a drawback that it is difficult to see because the processing for increasing the contrast of the hologram image has not been performed. In Document 6, an image projection film is an essential component, but it is difficult to prepare an optical member that holds image information for projection in a limited space.

Japanese Patent Laid-Open No. 10-43382 describes an example in which two display bodies are synthesized using a half mirror or a hologram combiner, and one of them is an example of displaying a stereoscopic image by a lenticular photograph or a hologram. However, an optical system for synthesizing becomes large, and it has been difficult to configure the optical system to fit in a gaming machine within a standard size, for example.

An example in which a hologram reproduction function and an audio reproduction function are simply combined is disclosed below.

Japanese Patent Application Laid-Open No. 2008-70478 discloses an example in which a sound reproducing function is incorporated in a hologram reproducing apparatus having an exterior part and a three-dimensional structure part in a structure in which a thin plate member is folded. However, simply opening the exterior part starts playback of the sound and stops it when it closes. For those who are observing still, the sound and other sounds are synchronized with the playback of the hologram image. There was no effect that the video from the medium was played back, and it was insufficient as a production effect.

Furthermore, the hologram has a problem that it cannot be properly viewed unless it is illuminated in a manner that meets the conditions at the time of recording. Holograms that have been put into practical use, excluding artistic works, are made to be reproduced with more than 99% illumination from obliquely above. The reason is that, regardless of whether it is sunlight or indoor lighting, there are almost no light sources above the position of the eyes for human life, so we tried to observe the hologram under general conditions. In this case, it is natural to illuminate from above. Therefore, when illuminating a conventional general hologram, it is possible to reproduce an image even if it is not optimal if it is irradiated with some light from diagonally above the hologram. However, if a hologram of a type that irradiates the hologram from obliquely below is also distributed, there is a problem that the hologram is mounted in the wrong direction when mounted on the playback device, and there is a problem that it cannot be viewed at all, which causes confusion in the market. Became.

  The holographic stereogram is not only held flat, but also held in a cylindrical shape and floats an image inside the MULTIPLEX HOLOGRAM (Lloyd Cross, 1976), and the ALCOVE HOLOGRAM (Anamorphic) held in a semi-cylindrical shape. Raytracing For Synthetic Alcove Holographic Stereogram, Michael A. Teitel, Massachusetts Institute of Technology Thesis, 1986) were studied by the 1980s, but they are all large-scale devices to hold by hand. There was no combination function. Japanese Patent Laid-Open No. 10-254338 “Image Reproduction Method and Image Reproduction Device” describes an edge-lit and compact cylindrical hologram as one that can be combined with a hand-held light. The function of diffusing light that does not contribute to appreciation for the purpose and using it for lighting and production is not considered, and light that is not diffused reaches the eyes, or conversely, a hologram reproduction image due to extra reflected light can be seen There was a problem of being fooled.

By the way, the conventional hologram display device described in Patent Document 1 illuminates the hologram with reproduction light to improve the visibility of the hologram image by limiting the positional relationship between the hologram, the light source, and the observer. The light source and the optical system to be used have a complicated and large structure, and are a three-dimensional structure having a large volume and weight. Therefore, the conventional hologram display apparatus requires a lot of labor for transportation and transportation.

Although the pen-type viewer described in Patent Document 2 has good portability, it is a device for illuminating a hologram to the last, and has a drawback that it takes time to prepare for observation.

Furthermore, the hologram package described in Patent Document 3 eliminates the risk of damage or damage to the hologram surface during transportation or transportation, while maintaining the relative positional relationship between the hologram and the light source during observation. Although it was intended to maintain an appropriate positional relationship, this is also a device for illuminating the hologram, and for other purposes, it is used as a function to brighten dark places or enhance decoration It was difficult to do. There have been other proposals to illuminate the hologram from a certain angle with improved portability, but in any case, a combination of a light source and a light diffuser gives a decorative effect to the hologram or observes the hologram. There was no such thing as giving a decorative effect when not.

Furthermore, as penlights used in concerts, etc., multi-color penlights as described in Patent Document 4 have been proposed, and flashlights and small penlights for the purpose of searching for keyholes in the event of a disaster or in the dark There are also various proposals, but in order to illuminate a hologram using this, it is necessary to understand the basic knowledge of which direction the light source must be illuminated, and it is used unless enlightened Was difficult.

Therefore, the object of the present invention is good portability, and it is possible to reproduce a holographic image satisfactorily for use as a flashlight, a penlight, or as a decoration light that impresses people. It is to provide a simple hologram observation function.

In addition to the display image, a hologram with a transparent substrate is placed on the viewer side, and when trying to produce a decorative effect, the hologram image contrast degradation, which can occur simply by combining, display It is intended to solve problems such as luminance degradation and resolution degradation.

Further, the present invention is intended to solve the problem that an effective rendering effect cannot be achieved when combined with an audio device or a background video device.

Further, it is an object of the present invention to solve the problem that the hologram medium and the hologram reproducing apparatus are not properly combined, and an image is not reproduced or an original characteristic does not appear even when reproduced, resulting in confusion.

In order to solve the above-described problems, the present invention has a hologram support portion that supports a hologram or a holographic stereogram, a light source, a battery, and a light diffuser, and there is a portion that diffuses the light source. In addition, in the optical path irradiated from the light source to the image area of the hologram or holographic stereogram, and within the direction area of at least 20 degrees up and down and 45 degrees left and right from the center of the area of the hologram The optical diffuser can be fixed in a state where there is no material other than a substantially transparent member, and when the light diffuser is illuminated, the diffused light from the light diffuser adversely affects the reproduction of the hologram or holographic stereogram. The illumination device is characterized in that it does not exist.

As an example of a preferable form, a moving image is provided to a stationary observer by causing the hologram and the light source to move relative to the observer. Further, when combined with an audio reproduction device or a video display device as a background, reproduction and synchronization control of the hologram image is performed.

Further, when a restriction condition occurs such that the observer side illuminates from above or below the hologram, the characteristic is described as a symbol mark on the hologram medium, and the hologram reproducing apparatus has a compatible hologram medium type. Is displayed as a similar symbol mark.

According to the present invention, the relative positional relationship between the hologram and the light source can be obtained while having a function that can be used in a disaster or emergency, such as a flashlight or a penlight, and a function that can be used for decoration or production in a concert or event. It can be easily installed and maintained as an appropriate positional relationship. Therefore, a high-quality hologram can be easily appreciated.

Furthermore, the light diffuser disposed in the illumination device of the present invention can also have a decorative property that cannot be expressed by a single hologram by being illuminated simultaneously or sequentially.

Furthermore, by combining and controlling the reproduction of a hologram image in combination with an audio reproduction device or a video display device as a background, the effect can be enhanced to a level that has not been possible in the past.

Furthermore, by clearly observing the viewing conditions at a glance on the hologram medium and the hologram reproducing apparatus, even if a plurality of different types of holograms are distributed, the hologram medium and the hologram reproducing apparatus can be reproduced without confusion.

Embodiments of the present invention will be described below with reference to the drawings. The present invention is applied when a hologram or a holographic stereogram is attached to a package, an exhibition device, a penlight, a display, a game machine, or the like.

Therefore, in the following, a holographic stereogram will be specifically described as an example of a hologram or a holographic stereogram attached to these devices prior to description of devices to which the present invention is applied.

First, the principle of exposure recording of element holograms on the hologram recording medium will be described.

As shown in FIG. 1, the hologram recording medium 3 is a recording layer made of a photopolymerization type photopolymer on a base film 4 that is a support material made of, for example, polyethylene terephthalate (hereinafter referred to as PET) film. A photopolymer layer 5 is formed, and a cover film 6 made of, for example, a PET film is deposited on the photopolymer layer 5 to form a so-called film coating type recording medium.

In such a hologram recording medium 3, as shown in FIG. 2A, the photopolymerization type photopolymer constituting the photopolymer layer 5 is in a state where the monomers M are uniformly dispersed in the matrix polymer in the initial state. is there. The photopolymerizable photopolymer is irradiated with the laser beam LA having a power of 10 mJ / cm @ 2 to 400 mJ / cm @ 2, and as shown in FIG. Is polymerized into a polymerized state.

As the photopolymerization type photopolymer is polymerized, the monomer M moves from the surroundings to cause non-uniformity in the density of the monomer M, thereby causing a refractive index modulation between the exposed and unexposed areas. Thereafter, as shown in FIG. 2C, the photopolymerization type photopolymer is irradiated with ultraviolet rays or visible light LB having a power of about 1000 mJ / cm 2 to complete the polymerization of the monomer M in the matrix polymer.

In the hologram recording medium 3, as described above, the photopolymerization type photopolymer constituting the photopolymer layer 5 changes its refractive index according to the incident laser beam LA, so that the object beam and the reference beam The interference fringes generated by the interference are recorded by exposure as changes in the refractive index.

Further, since the hologram recording medium 3 is configured as a so-called film coating type recording medium, a step of performing a special development process after exposure recording is not required. Therefore, by recording a hologram image using such a hologram recording medium 3, a structure for performing a development process in the holographic stereogram manufacturing apparatus becomes unnecessary, the apparatus configuration can be simplified, and the holographic structure can be simplified. Stereograms can be made quickly.

Here, a holographic stereogram production apparatus for producing a holographic stereogram using the hologram recording medium 3 described above will be described.

In the following description, it is assumed that a holographic stereogram having parallax information in the horizontal direction is produced by exposing and recording a plurality of strip-shaped element holograms on one hologram recording medium 3. However, it can be said that the holographic stereogram may have parallax information in the horizontal and vertical directions by, for example, exposing and recording a plurality of dot-shaped element holograms on one hologram recording medium. Not too long.

As shown in FIG. 3, the holographic stereogram manufacturing apparatus 10 exposes and records a holographic stereogram image on a hologram recording medium 3 made of a photosensitive film. The holographic stereogram production apparatus 10 includes an image data processing unit 11 that processes image data to be exposed and recorded, a control computer 12 that comprehensively controls the holographic stereogram production apparatus 10, and a holographic stereogram. And a holographic stereogram production unit 13 having an optical system for production.

The image data processing unit 11 includes at least an image processing computer 14 and a storage device 15. For example, captured image data including parallax information supplied from a parallax image sequence imaging device 1 having a multi-lens camera, a mobile camera, or the like. A parallax image data sequence D3 is generated based on image data such as D1 and computer image data D2 including parallax information generated by the image data generation computer 2.

Note that the captured image data D1 is a plurality of image data obtained by, for example, simultaneous shooting with a multi-lens camera or continuous shooting with a mobile camera, and disparity information is included between the image data constituting the captured image data D1. included. The computer image data D2 is a plurality of image data created as, for example, CAD (Computer Aided Design) or CG (Computer Graphics), and parallax information is included between the image data constituting the computer image data D2. .

The image data processing unit 11 performs predetermined image processing for the holographic stereogram by the image processing computer 14 on the parallax image data sequence D3 based on the captured image data D1 and / or the computer image data D2. Hologram image data D4 is generated. The hologram image data D4 is temporarily stored in a storage device 15 such as a memory or a hard disk device. As will be described later, when the image data processing unit 11 exposes and records an element hologram image on the hologram recording medium 3, the image data processing unit 11 performs element hologram images for each image from the hologram image data D4 stored in the storage device 15. Data D5 is sequentially read out, and the element hologram image data D5 is supplied to the control computer 12.

The control computer 12 controls the holographic stereogram producing unit 13 so that the element display image based on the element hologram image data D5 supplied from the image data processing unit 11 is part of the holographic stereogram producing unit 13. The hologram recording medium 3 provided is sequentially exposed and recorded as strip-shaped element holograms. At this time, the control computer 12 controls the operation of each mechanism of the holographic stereogram production unit 13 as described later.

In the holographic stereogram production unit 13, each member constituting the optical system is disposed and supported on a support substrate (optical surface plate) (not shown), and this support substrate is supported on the apparatus housing via a damper (not shown). The structure is made. The holographic stereogram producing unit 13 includes an incident optical system, an object optical system, and a reference optical system as an optical system for producing the holographic stereogram. Since the holographic stereogram manufacturing apparatus 10 uses the hologram recording medium 3 that is a photosensitive material, the apparatus housing has a structure that retains at least the light shielding property of the optical system.

As shown in FIG. 4A, the holographic stereogram preparation unit 13 is arranged as an incident optical system on a laser light source 21 that emits laser light of a predetermined wavelength and on the optical axis of the laser light L1 from the laser light source 21. The shutter mechanism 22 that makes the laser beam L1 incident or blocked at the subsequent stage and the half mirror 23 that divides the laser beam L1 into the object beam L2 and the reference beam L3.

The laser light source 21 is composed of a laser device such as a semiconductor-excited YAG laser device, a water-cooled argon ion laser device, or a water-cooled krypton laser device that emits laser light L1 having a single wavelength and good coherence.

The shutter mechanism 22 is opened / closed by a control signal C1 output from the control computer 12 in response to the output timing of the element hologram image data D5, and causes the laser light L1 to enter a subsequent optical system. Alternatively, the incidence on the subsequent optical system of the laser beam L1 is blocked.

The half mirror 23 divides the incident laser light L1 into transmitted light and reflected light. The laser light L1 uses the transmitted light as the above-described object light L2, while the reflected light is used as the reference light L3. The object light L2 and the reference light L3 are incident on an object optical system or a reference optical system provided in the subsequent stage.

Although not shown, the incident optical system may be provided with a mirror or the like for the purpose of changing the traveling direction of the laser light L1 as appropriate so that the optical path lengths of the object light L2 and the reference light L3 are the same. . Further, the shutter mechanism 22 may be configured, for example, such that a shutter piece is mechanically driven or an electronic shutter using an acousto-optic modulator (AOM). . That is, the shutter mechanism 22 only needs to be openable and closable so as to shield and transmit the laser light L1.

Further, as shown in FIGS. 4A and 4B, the holographic stereogram preparation unit 13 includes a mirror 24, a spatial filter 25, a collimator lens 26, a projection lens 27, a cylindrical lens 28, a mask 29, and the like as an object optical system. Each of these optical components is sequentially arranged from the input side along the optical axis.

The mirror 24 reflects the object light L <b> 2 that has passed through the half mirror 23. The object light L <b> 2 reflected by the mirror 24 is incident on the spatial filter 25.

The spatial filter 25 is configured by combining, for example, a convex lens and a pinhole, and isotropically reflects the object light L2 reflected by the mirror 24 in accordance with the display surface width of a transmissive liquid crystal display 30 described later. Enlarge.

The collimator lens 26 converts the object light L <b> 2 expanded by the spatial filter 25 into parallel light and guides it to the transmissive liquid crystal display 30.

The projection lens 27 slightly diffuses the object light L 2 and projects it onto the cylindrical lens 28. The projection lens 27 contributes to improving the image quality of the produced holographic stereogram by slightly diffusing the object light L2.

The cylindrical lens 28 condenses the collimated object light L2 in the lateral direction.

The mask 29 has a strip-shaped opening, and the object light L 2 collected by the cylindrical lens 28 that has passed through the opening is incident on the hologram recording medium 3.

In the object optical system, a transmissive liquid crystal display 30 is disposed between the collimator lens 26 and the projection lens 27. Element hologram images are sequentially displayed on the transmission type liquid crystal display 30 based on the element hologram image data D5 supplied from the control computer 12. The control computer 12 supplies a drive signal C2 to the recording medium feed mechanism 34 of the hologram recording medium 3 to be described later in response to the output timing of the element hologram image data D5, and controls the operation thereof. The feeding operation of the hologram recording medium 3 is controlled.

In such an object optical system, the object light L2 that is in the form of a thin beam divided and incident from the incident optical system is magnified by the spatial filter 25 and incident on the collimator lens 26 to be converted into parallel light. Is done. Further, in the object optical system, the object light L 2 incident on the transmissive liquid crystal display 30 via the collimator lens 26 is image-modulated according to the element hologram image displayed on the transmissive liquid crystal display 30. At the same time, it enters the cylindrical lens 28 via the projection lens 27. Then, the object optical system causes the image-modulated object light L2 to enter the hologram recording medium 3 through the opening of the mask 29 while the shutter mechanism 22 is opened, and corresponds to the element hologram image. This is recorded by exposure.

Further, the holographic stereogram preparation unit 13 includes a spatial filter 31, a collimator lens 32, and a mirror 33 as a reference optical system, and these optical components are sequentially arranged from the input side along the optical axis. Yes.

Unlike the spatial filter 25 in the object optical system described above, the spatial filter 31 is configured by combining, for example, a cylindrical lens and a slit, and the reference light L3 reflected and divided by the half mirror 23 has a predetermined width, specifically First, it is enlarged in a one-dimensional direction corresponding to the display surface width of the transmissive liquid crystal display 30.

The collimator lens 32 converts the reference light L3 magnified by the spatial filter 31 into parallel light.

The mirror 33 reflects the reference light L3, guides it to the rear of the hologram recording medium 3, and makes it incident.

The holographic stereogram preparation unit 13 including such an optical system includes an object optical system that is an optical system through which the object light L2 divided by the half mirror 23 passes and a reference optical that is an optical system through which the reference light L3 passes. The optical path length with the system is almost the same. Therefore, the holographic stereogram producing unit 13 can produce a holographic stereogram in which the coherence between the object light L2 and the reference light L3 is improved and a clearer reproduced image can be obtained.

Further, the holographic stereogram production apparatus 10 includes a recording medium feeding mechanism 34 that intermittently feeds the hologram recording medium 3 by one element hologram in the direction indicated by the arrow in FIG. 4B.

The recording medium feeding mechanism 34 intermittently drives the hologram recording medium 3 based on the drive signal C <b> 2 supplied from the control computer 12. Further, in the holographic stereogram producing apparatus 10, the above-described shutter mechanism 22 is operated based on the control signal C1 supplied from the control computer 12 in conjunction with the operation of the recording medium feeding mechanism 34, and the laser light L1. Open the light path.

Such a holographic stereogram production apparatus 10 is supplied with a drive signal C2 corresponding to a one-element hologram from the control computer 12 to the recording medium feeding mechanism 34 every time exposure recording for one element image is completed. Then, the hologram recording medium 3 is driven to travel along the travel path by an amount corresponding to the one-element hologram, and the unexposed part is made to correspond to the opening of the mask 29 and stopped. The holographic stereogram manufacturing apparatus 10 is configured such that vibration generated in the hologram recording medium 3 in accordance with the traveling operation of the hologram recording medium 3 is quickly stopped. Here, the hologram recording medium 3 is made of a long photosensitive film and is wound around a supply roll that is rotatably provided inside a film cartridge that is held in a light-shielded state, for example, although not shown. Yes. When the film cartridge is loaded into the holographic stereogram manufacturing apparatus 10, the hologram recording medium 3 is fed into the holographic stereogram manufacturing apparatus 10 and is driven to travel along the traveling path by the recording medium feeding mechanism 34. .

In this state, the holographic stereogram manufacturing apparatus 10 opens the shutter mechanism 22 to provide the hologram recording medium 3 with the object light L2 and the reference light L3 that are image-modulated from the front and back surfaces of the hologram recording medium 3. The interference fringes corresponding to the element hologram image are recorded by exposure. The holographic stereogram production apparatus 10 is supplied with a drive signal C2 from the control computer 12 to the recording medium feeding mechanism 34 when the exposure recording of the one-element image is completed, and travels the hologram recording medium 3 quickly by a predetermined amount. Drive and stop.

Further, the holographic stereogram manufacturing apparatus 10 performs a fixing process including an ultraviolet irradiation process on the hologram recording medium 3 and a heating process on the hologram recording medium 3 at a predetermined temperature by a fixing processing unit (not shown). A holographic stereogram image exposed and recorded on the hologram recording medium 3 is fixed. The holographic stereogram production apparatus 10 sequentially cuts out the hologram recording medium 3 on which the fixing process has been performed into a predetermined size for each holographic stereogram image, and discharges it as a single holographic stereogram to the outside.

The holographic stereogram manufacturing apparatus 10 sequentially performs this operation below, thereby sequentially exposing and recording a plurality of holographic stereogram images on the long hologram recording medium 3, thereby producing one holographic stereogram. A holographic stereogram in which a gram image is recorded by exposure is prepared.

Next, a specific example of a lighting device to which the present invention is applied and to which a holographic stereogram created as described above and various holograms are attached will be described. The various holograms are not limited to the Lippmann type (volume type) one-step holographic stereogram with lateral parallax as described above, but a full parallax stereogram with vertical parallax added, a live-action hologram taken by laser irradiation of a model, etc. Also included are holograms replicated using them as masters, so-called embossed holograms of surface relief type, diffraction gratings and the like. Hereinafter, unless otherwise specified, a holographic stereogram is also included in a hologram as a kind of hologram.

As a first embodiment, a penlight 500 as shown in FIG. 5 will be described. The penlight 500 has a light source support 55 containing the light sources 54a, 54b, 54c and the battery 55, a bracket portion 60 fixed to the light source support 50, and a movable thin plate from the bracket portion via a hinge 53. It has a light guide diffuser 51 formed of a resin material or the like.

The light guide diffuser 51 has a portion 52 whose surface roughness is partially increased, and the light incident from the end surface 61 of the light guide diffuser 51 does not emit a portion having a small surface roughness. Only the part with high roughness is diffused in the normal direction of the surface. In this embodiment, the surface roughness is increased by methods such as sandblasting, etching, and laser marking. However, the present invention is not limited to this, and various methods can be used. Further, a partially milky white material may be made of brick. A colored diffusing material, a fluorescent paint, a material that reacts with black light, cellophane, or the like may be formed partially or entirely. It may be a surface relief type or Lippmann type diffraction grating, a hologram, or the like. The shape is not limited to a pattern such as a star, but may be formed of letters, alphanumeric characters, and the like.

In addition, a reflection hologram is sandwiched and fixed by a clip 59 directly or via a hologram frame frame 62 as shown in FIG. The light guide diffuser 51 may be fixed not directly by a clip but directly by an adhesive, an adhesive, or the like.

The entire light guide diffuser 51 is connected to the hinge 53 and is rotatable. In the state of FIG. 5A, light from the light sources 54 a, 54 b, 54 c such as a light emitting diode (LED) disposed inside the light source support 50 is transmitted to the light guide diffuser 51. Easy to enter from the end face 61. In the state of FIG. 5B, no light enters from the end face of the light guide diffuser 51, but the hologram 58 is at a position where it can be irradiated from a predetermined angle. The predetermined angle is adjusted to an appropriate illumination angle determined by the hologram 58. In this example, a line connecting the light source 54b and the center of the hologram 58 and a normal line of the surface of the hologram 58 are used. The angle formed is set to 45 °.

The angle formed between the light guide diffuser 51 and the bracket portion 60 can be rotated between 0 degree and 45 degrees, but the stopper a56 and the stopper b57 do not spread to other angles. Yes. That is, it moves continuously between the first form for illuminating the decoration center and the second form for holographic observation, and does not reach a state beyond that.

Further, a mechanism (not shown) can be fixed in a state of 0 degrees and 45 degrees unless a certain amount of external force is applied. In other words, it has a mechanism that can be fixed at each position of the first form in which illumination is centered on the decoration and the second form in which hologram observation is performed.

As the light source, a red LED 54a, a green LED 54b, and a blue LED 54c are incorporated in a light source support. When in the state of FIG. 5A, the respective LEDs are sequentially lit or blinked, and the decorativeness can be enhanced.

When the red LED 54a, the green LED 54b, and the blue LED 54c are all turned on in the state of FIG. 5B, a full-color hologram can be optimally illuminated. The luminance balance of the red LED 54a, the green LED 54b, and the blue LED 54c can be adjusted according to the characteristics of the hologram.

The light source support 50 has a switch (not shown). When the light source support 50 is in the state shown in FIG. 5A, the lighting of the LED can be started by pressing the switch. The push button switch is turned off automatically after lighting for a certain time. If you forget to turn it off, it is a function to prevent the battery from being consumed even though it is not being used. Alternatively, it may be lit only after the switch is pressed until it is pressed again. Alternatively, it may be lit only while the switch is kept pressed.

The position of the stopper 56b or the light introduction end face 61 includes a micro switch, an optical switch, or the like (not shown), and the light emission control of the light sources 54a to 54c may be changed according to the position of the introduction diffuser 51. When in the state of FIG. 5B, there is a desire to observe the hologram with higher brightness than the penlight mode of FIG. Before reaching the state of FIG. 5 (b), if the LED is illuminated with high brightness, it consumes power wastefully, and light that is dazzling directly to the human eye when used as a penlight. Therefore, it is possible to control so as not to emit light with high brightness except in the state of FIG. Thus, it has a discriminating device capable of discriminating whether it is the first mode for illuminating the decoration center or the second mode for the purpose of holographic observation. Different light source control suitable for the second embodiment can be performed.

Or you may enable it to control how to shine only by moving the position of a light guide diffuser, without using a push switch, a slide switch, etc. For example, when the state shown in FIG. 5A is set, the light diffuser shines by the penlight function, R, G, and B are sequentially switched, blink for 1 minute, turn on, and then turn off. When set to the state of FIG. 5B, R, G, and B are simultaneously illuminated in the high luminance mode, illuminate the hologram, and turn off after 30 seconds. This is an example, and the light emission state and the brightness can be controlled in various ways. That is, the light source for illuminating the hologram support portion may be turned on only for a predetermined time after the state determining device is set to the second mode for illuminating the hologram observation center, and then turned off.

In the first embodiment, since the red LED 54a, the green LED 54b, and the blue LED 54c are built in the light source, the same light source can be used for both the penlight function and the hologram illumination function, which is efficient. In addition to this, a white LED may be provided. In this case, in the state of FIG. 5 (a), red, green, and blue LEDs are individually turned on sequentially and the white LED is left off, and in the state of FIG. 5 (b), only the white LED is left. It is also possible to make a variation such that the white LED shines with high brightness and the red, green, and blue LEDs shine with low brightness in a decorative manner.

The sectional structure of the hologram layer used in the first embodiment will be described with reference to FIG. In the hologram medium 70 with a frame, a hologram recording layer 72 is sandwiched between base layers 72 and 73 such as PET, and is adhered with an adhesive 72 so that the periphery thereof is protected by frames 74 and 75. Since the hologram recording layer 72 is transparent and both the frame A74 and the frame B75 are cut out, the back can be seen as a see-through through the hologram image.

In the hologram, it is important to enter light from the top and bottom, the top and bottom of the image, and light from obliquely above or obliquely from below. In particular, since the Lippmann hologram has interference fringes formed by refractive index modulation inside the recording layer, its orientation is difficult to understand until it is irradiated with illumination light. When the hologram layer is transparent in the structure of FIG. 8, it is easy to make a mistake as to how to set it including the front and back. In FIG. 11, it is assumed that the Lippmann hologram image can be normally viewed by entering light from obliquely above, and the image is hardly visible when rotated about the B axis and reversed 180 degrees. When rotated about the A axis and reversed 180 degrees, the hologram appears to be an inverted image, but it also becomes a so-called pseudoscopic image in which the depth and the front are reversed. That is, it is necessary to observe according to the recommended reproduction conditions set at the time of producing the hologram. Conventional holograms are made to be reproduced by illumination from obliquely above 99% or more. The reason is that, regardless of whether it is sunlight or indoor lighting, there are almost no light sources above the position of the eyes for human life, so we tried to observe the hologram under general conditions. In this case, it is natural to illuminate from above. On the other hand, the inventors have proposed a hologram combined with a light source, and the present invention also shows many examples in which the observer is irradiated with the hologram from obliquely below the hologram. In the world, if a hologram to be illuminated from above and a hologram to be illuminated from below are mixed, the observer will be confused as to which illumination should be performed after recognizing that the medium is a hologram.

Therefore, in the present invention, in order to make it possible to understand the front and back of the hologram, the top and bottom of the image, and the direction of the incident reproduction light without irradiating illumination light, the hologram medium or its frame is shown in FIGS. The mark is printed. First, the observer holds the hologram medium so that the mark in FIG. 12 looks upright. That is, it is confirmed that the arrow points upward and the UP character is not a mirror image. If it is printed on an opaque medium, the surface on which the mark of FIG. 12 can be seen is the front, and it is certain that it is on the viewer side, but if it is printed on a transparent medium, it may be mistaken. For this reason, non-symmetrical characters or symbol marks such as UP are printed. In addition, if there is a mark in FIG. 13, if there is a mark in FIG. 13A, the image is reproduced by irradiating the light source from above the observer side. If there is an arrow mark in FIG. 13B, the image is reproduced by irradiating the light source from below the observer.

FIG. 14 shows variations of marks representing the optimal illumination incident light. Strictly speaking, the incident direction of the optimum illumination light is determined including the angle. In (a), assuming that the observer observes from the normal direction of the hologram, the direction obliquely upward 45 ° with respect to the normal direction of the hologram It means that the light source is incident from. Similarly, (b) means that the light source is incident obliquely below the normal line of the hologram from a direction of 60 °. Further, in (c) and (d), in addition to the angle, R (an acronym for Reflection) indicating a reflection type in which light enters from the observer side of the hologram surface, or a transmission type in which light enters from the opposite side of the observer T (Transmission acronym) indicating was also added. In addition, an edge-lit type E that enters from the end face of the medium may be added between the reflective type and the transmissive type. In addition, the type of recommended light source, wavelength, parallelism, and the like may be described. In addition, when such a mark cannot be printed on the observation surface side of the hologram, it may mean that it is written on the back surface by indicating an arrow with a dotted line as shown in (e).

The mark in FIG. 12 is not necessarily required if characters or the like are printed on the hologram surface or the medium surface on which the hologram is attached or incorporated. This is because when the characters are printed, the top and bottom and the front and back can be easily determined. In addition, it is easy to understand if the recommended illumination light mark as shown in FIGS. 13 and 14 is formed.

In the present embodiment, the frame frame 62 is shaped so that it can be attached to the lighting device without making a mistake even if there is no recommended illumination light mark. As shown in FIG. 9, the frame frame 62 of the hologram is formed from a cross-sectional view, a frame A 74, an adhesive 76, and a frame B 75 in FIG. 8, but provided with a hole 64 that penetrates all these materials.

On the other hand, the illuminating device of this embodiment is formed with a cylindrical convex portion 63, and the diameter of the cylindrical convex portion is smaller than the through hole 64 provided in the frame of the hologram medium. When mounting the hologram medium 70, first, the through hole 64 is inserted into the columnar convex portion of the apparatus and then fixed by the clip 59. If an attempt is made to attach the top, bottom, left, right, front, or back in the wrong direction, the through hole 64 of the hologram medium and the columnar convex portion 63 of the illumination device do not fit and do not fit, thus preventing erroneous insertion. The convex portion may be a hemispherical round protruding convex portion instead of a cylindrical shape, or a cylindrical portion having a large chamfer. By doing so, the through hole 64 and the convex portion 63 are fitted and positioned by simply sliding along the guide and being pushed in. At the same time, it also serves as a stopper that is not naturally discharged unless a force is applied to remove it. be able to.

The example in which the direction of the medium can be defined by the columnar convex portion and the through hole has been described, but the present invention is not limited to this as long as the top, bottom, left, right, and back are determined uniquely. For example, even if only one of the corners of the four corners has a different shape from the other, the overall structure of the frame is asymmetric, and processing that matches that shape is applied to the lighting device side. good.

In the above example, the hologram substrate is made transparent so that the background can be seen through, but the black or dark substrate or adhesive on the opposite side of the hologram recording layer 72 to the observer. The background may be difficult to see. In that case, there is an advantage that the contrast of the hologram image is increased to make it easy to see, and the front and back are not mistaken. That is, on the side of the frame B75, the hologram portion is not a through hole, but may be an unprocessed base material to provide light shielding properties.

Various materials such as paper, plastic, metal, and wood can be selected as materials for the frame A74 and the frame B75 constituting the frame frame 62. The frame A74 and the frame B75 are connected to each other in advance so that a crease is formed. After positioning the hologram, the frame A74 and the frame B75 are displaced when the hologram is positioned and folded so that it cannot be removed again with an adhesive. It is possible to stick together.

The adhesive may be re-peelable. Moreover, it is also possible to fix by fitting or bending in the shape processed into the frame A74 and the frame B75 without using an adhesive.

The frame frame 62 is formed with a through hole or a recess at a position 65 so that a strap, a key, an LED light source, or the like can be connected by itself. If a key chain type LED light source is used in combination, simple observation is possible. Further, if the holes 65 of the frame frames of a plurality of holograms are connected by a chain, string, rubber or the like, they are not easily lost. If it is connected to the illumination device according to the present invention, it is possible to exchange different holograms at the intention of the observer and attach them to the illumination device for observation. In order to achieve such an object, the lighting device of the present invention has been designed in such a way that, when mounted, the parts combined in the position of the hole 65 in FIG. 9 do not hit the lighting device. Yes.

In the first embodiment, when placed on the surface of a desk or the like as shown in FIG. 6 in the state of FIG. 5B, the bracket portion 60 and the stopper a56 are grounded so that the hologram can be held without being held by hand. You can appreciate it.

Assuming an appreciation form as shown in FIG. 6, the orientation of the hologram is as shown in FIG. Most of the popular holograms are produced in the orientation shown in FIG. 9 so that the viewer can easily observe with illumination from above such as ceiling lighting and sunlight. For this reason, even if the hologram medium of FIG. 10-a is observed separately from the illuminating device, it is only necessary to irradiate light from obliquely above 45 ° as in the case of a general hologram. is there.

When the embodiment shown in FIGS. 5 (a) and 5 (b) is held on the assumption that it is used as a penlight, the light guide diffuser from the light source support 50 as shown in FIG. 5 (a). With 51 facing up, the image is placed upside down, but in the illumination position relationship as a penlight, the hologram image is hardly reproduced even with external light above, so the unnecessary image is not reproduced, rather, It is convenient to reproduce an impact image only during viewing.

Although it has been described that the symbol mark as shown in FIGS. 12 to 15 is described on the hologram medium side, it is preferable that the same symbol mark is also provided on the hologram reproducing apparatus side. As described so far, it is useful that the hologram medium can be mounted only in a normal orientation, but further, the hologram reproducing apparatus side has a characteristic of the reproducing apparatus side, that is, an oblique direction. If you can visually determine whether it is a device for irradiating from below, a device for irradiating from obliquely above, or what the illumination angle is, select an appropriate playback device. It is also convenient to do. In the present invention, since it is described with a symbol mark, it can be expressed in a small area, and anyone who speaks any language can understand intuitively in common.

When the reproducing apparatus has a mechanism for adjusting the irradiation angle to the hologram, as shown in FIG. 45, the irradiation angle range is, for example, 38 ° to 62 ° from the top with respect to the normal of the hologram, or The angle range may be displayed from 40 ° to 60 ° from the bottom.

As a second embodiment, a case where a hologram medium formed as shown in FIG. 10B is mounted in FIG. 5A will be described. If it is held in the hand as shown in FIG. 7A in the state of FIG. 5A, it can be used as a penlight. When this is brought into a state as shown in FIG. 5B and tilted as shown in FIG. Further, FIG. 15 shows an example in which the same state as FIG. 7B is inserted and fixed to the cradle 81 holding the light source support so that it can be reproduced without holding it.

In the case of this second embodiment, since the hologram can be observed only by changing the angle with the light source support, the operation can be simplified. In the case of the first embodiment, if the light source support part is too large compared to the light guide diffuser, the stability will deteriorate when placed as shown in FIG. 6, or the light source support part will be obstructive during observation. However, in the second embodiment, the stability can be improved and the configuration can be made so as not to hinder the observation, so that the degree of freedom of design is improved.

In the case of the second embodiment, the hologram medium to be used needs to irradiate the observer with illumination light obliquely from below, and is different from holograms that are generally distributed. If you don't do this, the problem may be that the observation method is difficult to understand. On the other hand, in the present invention, as described above, marks such as those shown in FIGS. 12, 13, and 14 are displayed on the hologram medium, so that the observer can understand the optimum illumination conditions without being confused. become.

In the second embodiment, when the cradle 81 is mounted as shown in FIG. 15, a power transformer and a contact are provided on the cradle side, and the power source is externally supplied to the light source support. May be made. In this case, the light source can be illuminated without depleting the battery built in the light source support. In addition, a storage battery that can be repeatedly charged may be built in the light source support so as to have a function of being mounted and charged. In the example of FIG. 15, it is assumed that the handle portion is a substantially cylindrical shape, and the recessed portion of the pedestal 81 is formed so that the central axis of the cylinder can be fixed in the range of 0 to 45 degrees with respect to the horizontal. This is because the hologram is easy to see when placed at an angle that looks down from above, and the surface on which the hologram is attached to the handle is approximately 45 degrees.

A third embodiment will be described with reference to FIG. As in the first embodiment, a hologram is mounted on a part of the light guide diffuser. The light source guided by the light guide diffuser is integrated with the light guide diffuser. It has a structure. In addition, a light source for illuminating the hologram is held by another hologram illumination light source support 151, and is connected to the light guide diffusion plate via a movable portion.

When not observing the hologram, as shown in FIG. 16 (a), the hologram illumination light source support 151 is housed in a handle that also serves as a battery housing together with the light source. Power is not supplied.

During hologram observation, as shown in FIG. 16B, when the hologram illumination light source support 151 is moved to a predetermined position, power is supplied to the hologram illumination light source.

A fourth embodiment will be described with reference to FIG. Although the structure is the same as that of the second embodiment, the light source support 950 is integrated with a battery housing portion that also serves as a hand portion, and the light source support includes L1, L2, L3, L4, L5, A total of seven white LEDs L6 and L7 are housed in a direction to irradiate the hologram portion with a substantially constant distance from each other. In a situation where the relationship between the position of the observer's eyes and the position of the hologram is fixed, when the illumination light moves, the hologram image changes accordingly. For this reason, as shown in FIGS. 18A to 18C, by sequentially illuminating the light sources L1 to L7, a visual effect is obtained that the stereoscopic image moves without the observer moving. As shown in FIG. 18B, when the luminance of the light source is gradation controlled, a smoother motion is reproduced than in the case of controlling as shown in FIG. Since the brightness of an image reproduced from adjacent LEDs changes smoothly, the decoration effect is also great. When the luminance of the light source is controlled as shown in FIG. 18C, it is also possible to continuously reproduce the three-dimensional image or moving image forward and backward in a loop.

L1 to L7 have been described as white LEDs, but each is composed of a plurality of light emitting elements such as red, green, and blue, and each may be controlled to emit light individually. Alternatively, the LEDs themselves may be white, and there may be individual color filters at the positions where the respective LEDs of the light guide diffuser 951 are incident. By doing so, it is possible to realize white reproduction suitable for hologram observation and multicolor development suitable for penlight decoration. Further, the number of light sources is not limited to seven.

As shown in FIGS. 17A and 17B, when a plurality of illuminations are performed as in L1 to L7, the effect can be expected as described above at the time of hologram illumination. It is possible to add a decoration effect or a message effect, such as highlighting the characters “LIVE!” One character at a time. In the mode of effectively viewing the hologram, it is important that only one light source or adjacent neighboring light sources emit light on the hologram surface. This is because multiple images can be seen when simultaneously irradiated from a plurality of light sources from different positions and angles. You can intentionally illuminate multiple light sources from different directions to create a mode that allows you to observe multiple images, but you can also enhance the decoration effect. Can be selected.

In the fourth embodiment, the bracket portion 960 can be rotated together by a hinge portion, and it is easy to observe when placed on a desk or the like after being shaped as shown in FIG. 17C. It can be fixed at an angle. A convex part and a concave part (not shown) are formed in the movable part, and can be fixed in the form as shown in FIG. 17B or FIG. 17C unless an external force is applied.

A fifth embodiment will be described with reference to FIG. Although the structure is the same as that of the fourth embodiment, only one LED in the L4 portion is disposed on the slide unit 982 on the slide rail 981, from the position of L1 to the position of L7. It has a structure that moves continuously while facing the hologram irradiation part direction. In the slide structure, the friction is extremely low, and the unit provided with the LED part also has a weight (not shown). Therefore, when the entire penlight 980 is tilted, the LED moves to the lowest position, The angle at which the hologram is irradiated changes. It is assumed that the penlight is shaken at a concert venue, etc., but it is often used while tilting to the left and right by hand, and accordingly, a decoration effect that different parts are irradiated when using the penlight, and a different hologram when observing the hologram You can expect image effects that allow you to see images.

As a modification, it may be driven by an elastic force such as a spring force or an actuator such as a motor without depending on gravity.

A sixth embodiment will be described with reference to FIG. In the penlight 600, a transparent hollow body 610 made of a transparent plastic member having a thickness of about 1 mm is fixed to an upper portion of a handle portion 619 for storing a battery 655, a switch 665, an electric circuit (not shown), and the like. A surface of the transparent hollow body 610 far from the observer has an opening 615, and a hologram holding part 614 is formed outside the opening 615. The hologram holding unit 610 includes a hologram guide 617 for supporting the hologram from the left and right and from the bottom to determine the position, and a light shielding body 616. The hologram holding section 610 slides the hologram into a space surrounded by the hollow body 610. Can be done. A convex part is formed on either or both of the hollow body side and the light shielding body side, and a hole is formed in a corresponding part on the hologram side. When the hologram is mounted, the convex portion on the apparatus side and the concave portion on the hologram side are combined to prevent the hologram from coming off naturally unless a force is applied. In addition, since the convex portion and the hole are formed at the left / right / up / down non-target positions, there is also an advantage that the front / back / up / down can be mounted without mistake. By doing so, it is possible to use a medium having the configuration as shown in FIG. 1 without using a frame as in the first embodiment.

Inside the transparent hollow body 610, a plurality of LEDs are arranged like L1, L2 to L7. Among these, immediately after the emission of the LEDs L2, L4, and L6, a mirror 813 is arranged and fixed by the mirror so as to face the central portion of the hologram. By using a mirror, it can be compactly arranged in the hollow body.

Immediately after the emission of L1, L3, L5, and L7, there is no mirror, and the hollow body is irradiated from the inside, but light is incident obliquely in a saw-like shape on the inside near the portion irradiated with the LED of the hollow body. An easy prism shape is formed, and the light is guided into the plastic member forming the hollow body at an angle nearly parallel to the component surface. Since the angle exceeds the critical angle, if the transparent hollow body is an ideal mirror flat plate, it will propagate through the plastic material as if guided from the end face, and light will exit from the surface. Not come. The decoration diffusing portion 611 has a minute unevenness on the surface of the hollow body, and only that portion appears to shine.

Since the hologram, light source, and each member are accommodated in the transparent hollow body 610, dust and dust are difficult to enter and the robustness is improved. However, since the observer sees the hologram through the hollow body 611, the minute unevenness It is not preferable that the processing hinders the observation of the hologram. Therefore, no member that diffuses light is present in the direction area at least 20 degrees up and down and 45 degrees left and right with respect to the observer's normal from the center of the hologram area. The observable area of the hologram depends on the specification of the hologram, but this is an area for viewing because the viewing hologram having a viewing angle in the left-right direction is generally formed at 20 degrees up and down and 45 degrees or more on the left and right. The gate for plastic molding was also arranged to avoid this position. The material of the transparent hollow body 810 is made of a material having a total light transmittance of 80% or more and a haze value of 10% or less so as not to deteriorate the brightness and image quality of the hologram, and a part of the member has a diffusibility. In order to prevent a significant adverse effect on the observation of the hologram even if there is, the diffusion part and the light-shielding part should not exceed 10% in area ratio.

The haze value indicates turbidity (cloudiness) and is determined from the ratio of diffusely transmitted light to total light transmitted. Specified in JIS-K-7105 and JIS-K-7136.
Haze (%) = Td / Tt x 100 (Td: diffuse transmittance Tt: total light transmittance)

Furthermore, if there is unnecessary reflection on the material surface of the hollow body 810, the amount of light contributing to the reproduction of the hologram is reduced and the image becomes dark, the unnecessary hologram image is reproduced by unnecessary light, or unnecessary reflected light is directly reflected. It may reach the observer's eyes and interfere with it. In order to avoid this, in this embodiment, the surface of the hollow body 810 is subjected to antireflection coating, moth-eye processing, and the like.

When L1, L3, L5, and L7 are blinked simultaneously or sequentially, a decoration effect as a penlight can be obtained, and if only one L4 is lit, a hologram can be observed. If L2, L4, and L6 are sequentially turned on, it is possible to appreciate the movement of the hologram image without moving the illumination device or the observer.

As a modification, immediately after the emission from the LEDs L1 to L7, all the half mirrors are arranged at the position 613, a part of the light of each LED is used for hologram illumination, and the rest is a hollow body It may be guided to the light diffuser. The ratio of the transmitted light and reflected light of the half mirror may be different for each LED.

The back side of the hologram, ie the opposite side of the viewer, is important. If a black light shielding member is placed at the position 616 in FIG. 20, it is possible to observe a hologram image with high contrast, but the see-through effect as described above cannot be produced. On the other hand, when light that does not diffuse from the bottom obliquely hits with a penlight on hand, if the penlight is turned on in front of many people, or if a person other than the observer is facing the person when observing the hologram, it will be too dazzling It can be a nuisance and, in the worst case, it can also damage your eyes. Therefore, in the present invention, an example using an anisotropic light-shielding body or an anisotropic diffuser is shown.

When the louver film, which has been commercialized for the purpose of preventing peeping on mobile phones and monitors, is placed on the shading body at the position 616 in FIG. 20, while creating a situation where the back can be seen through from the front, and from diagonally below The illumination light of the LED can be blocked so that it does not pass through the back. As an example, a PF series manufactured by 3M can be used.

Next, a case where an anisotropic diffuser is arranged at a position 616 in FIG. 20 will be described. If you use a specklegram that records speckles, or a resin film in which parts with different refractive indexes are distributed in an irregular shape, it will appear cloudy in a certain direction and transparent when viewed from other angle ranges. Looks like a film. “Lumisty (registered trademark of Sumitomo Chemical Co., Ltd.)” can be given as one having such a function.

Lumisty is formed from at least two types of resin compositions containing at least one of a photopolymerizable monomer and oligomer.

Examples of the photopolymerizable monomer or oligomer include 2,4,6-tribromophenyl acrylate, tribromophenoxyethyl acrylate, 2-hydroxy-3-phenoxypropyl acrylate, tetrahydrofurfuryl acrylate, ethyl carbitol acrylate, and pentenyl. Examples thereof include oxyethyl acrylate, phenyl carbitol acrylate, polyol polyacrylate, isocyanuric acid skeleton polyacrylate, melamine acrylate, hydantoin skeleton polyacrylate, and urethane acrylate.

As each resin composition constituting Lumisty, resin compositions having different refractive indexes are used. As a combination of each resin composition, for example, two types selected from monomers, one type of monomers and one type of oligomers or two types selected from oligomers, or one or more types of monomers or oligomers were added to these combinations. Things. From the viewpoint of securing the diffusion angle in the diffused light, the refractive index difference between at least two of the resin compositions in these combinations is preferably 0.01 or more.

As a composition constituting Lumisty, a photopolymerization initiator, a plasticizer, a stabilizer, a filler having an average particle size of 0.05 to 20 μm, an ultraviolet absorber, a compound having no photopolymerizability, and the like are further contained. Also good.

When such an optically anisotropic diffuser is arranged on the back side of the hologram, the back of the hologram image becomes transparent and has a see-through effect. On the other hand, when viewed from the traveling direction of the LED light, it becomes diffuse light. Therefore, it is possible to enjoy an effective decoration effect as a penlight without feeling dazzling.

In the sixth embodiment, the anisotropic light shielding body and the anisotropic diffusing body are disposed on the illumination device side, but may be disposed on each hologram. That is, as shown in FIG. 27, a transparent base material 72, a hologram medium 71, a transparent base material 73, a louver film 77, and a transparent base material 78 are arranged in this order from the observer side.
When the louver film 77 is made of silicon rubber, it is easy to adhere to the base material 73 without air. When a louver film that transmits light from the front and shields light from an oblique angle is used, the background is seen through, but the illumination light from 45 ° is shielded and the medium is loaded In addition, it is possible to prevent a person other than the observer of the hologram from being dazzled when viewed from behind. The specifications such as the angle of the louver are not limited to this, and for example, a light that blocks light from the front and transmits light from an oblique direction may be arranged. In that case, the contrast at the time of observing the hologram can be improved, and the LED light can be transmitted as it is, so that it can be used like a flashlight. If these anisotropic light shields and diffusers are arranged not on the lighting device side but on the medium to be exchanged, it is possible to enjoy different effects for each medium.

As described so far, as an example of disposing an anisotropic light-shielding body, anisotropic diffuser, or functional body such as a simple light-shielding body or diffuser on the side opposite to the observer, a functional body May be arranged on the illumination device side or on the hologram medium side. Furthermore, the hologram medium, the functional body, and the illumination device are separated from each other, and the hologram medium and the functional body may be inserted into the illumination device in an overlapping manner.

Next, a seventh embodiment will be described using the penlight 700 of FIG. Unlike the sixth embodiment, an opening 720 is provided in the range in which the hologram pasted on the hologram pasting portion 714 is observed. By doing so, the image quality of the hologram does not deteriorate even if the hollow body casing 710 has poor surface roughness. Rather, the entire housing 710 may be a light diffuser. In addition, a sponge-like light diffuser 721 is disposed at the top of the housing, and LEDs, LX1, and LX2 that illuminate the light diffuser 721 are disposed separately from the light sources L1 to L7 that illuminate the hologram. The lower portion of the handle portion 719 is thick and can be viewed on a table or the like.

Next, an eighth embodiment will be described using the penlight 800 of FIG. A transparent hollow sphere A809 smaller than the hollow hollow sphere B809 is rotatably held via a hinge 807, and a liquid 808 is filled therebetween. In this liquid, decorative diffuser pieces 811 made of a material having a specific gravity slightly smaller than that of the liquid are dispersed, and if left in a stationary state, they gather at the top in the figure. The LED 813 is irradiated toward the inside of the transparent hollow sphere A809 and the hologram 815 attached to the hologram support portion 814 to reproduce the hologram image. When the penlight 800 is shaken as a whole, the decoration diffuser 811 is dispersed in the liquid, and the illumination light from the LED 813 is diffused, thereby improving the decoration effect. The weight 812 is fixed at an eccentric position inside the transparent hollow sphere, and is held at an angle as shown in FIG. 23. Further, when the handle portion 819 is moved so as to rotate about the axis, it is shown in the top view of FIG. Move in the direction of the arrow. There are a battery and an electromagnet (not shown) inside the handle part, and if the weight 812 is made of a permanent magnet, it attracts or repels between the electromagnet and the weight. By reciprocatingly rotating with respect to B, the effect of moving the hologram image can be obtained.

Next, as a ninth embodiment, a hologram 820 with a liquid hourglass will be described with reference to FIG. The handle portion of the eighth embodiment is replaced with a table 821, and a flange 822 is attached to the outside of the transparent hollow sphere B810 so as to be fitted with a guide 824 provided on the table. A transparent hollow sphere B810, a liquid 808, and a transparent hollow sphere A809 are transmitted in order from the LED fixed inside the pedestal 821, and the hologram 815 is irradiated at an angle of 45 degrees downward to reproduce the hologram image. A decoration diffuser piece 811 having a specific gravity slightly lower than that of the liquid is dispersed in the liquid 809. When the portion inside the transparent hollow sphere B is rotated 180 degrees with the flange fitted to the guide until the top and bottom are turned upside down, the decoration diffuser piece 811 at the bottom gradually rises upward. In the process, the light applied to the hologram from the LED is blocked or diffused, but as time passes, the decorative diffuser piece 811 gathers in the upper part and can be observed.

The flange portion has a notch as shown at 823 and a similar notch on the opposite side of 180 ° to the flange portion, so that the hologram is fixed at a position facing the hologram by a positioning member (not shown).

Silicon oil was used as the liquid to be sealed. By using highly viscous oil, the moving speed of the decorative diffuser can be reduced. The gap between the transparent hollow sphere B180 and the transparent hollow sphere A809 is substantially uniform in FIG. 24, but a slit may be provided so as to restrict the flow path. The decoration diffuser piece 811 is not limited to a solid such as a fine particle, a colored particle, a phosphorescent material, and a phosphor, but may be a liquid that does not mix with the liquid, or a gas. The decoration diffuser piece 811 has a specific gravity smaller than that of the liquid, so that the decoration diffuser pieces gather at the upper part in a stationary state, but conversely, the one with a larger specific gravity is chosen and gathered at the lower part. Also good. Furthermore, it is possible to select the one having substantially the same specific gravity at normal temperature and normal pressure, and the decorative diffuser changing whether it goes up or down due to environmental changes such as atmospheric pressure and temperature.

If the hologram is a multiplex recorded Lippmann hologram that has been subjected to multiple exposure at different reference beam angles or two holograms with different reference beam angles superimposed, it will be different when reversed 180 degrees It is also possible to reproduce a hologram image.

A tenth embodiment will be described using the columnar illumination device 850 of FIG. A hologram 852, a light diffuser 853, a hologram illumination LED 854, a light diffuser illumination LED 855, a battery 856, a switch (not shown), an electric circuit, and the like are housed in a transparent cylindrical casing 851. In the decoration mode, after the LED 855 sequentially illuminates the light diffuser 853, in the hologram illumination mode, the hologram is illuminated from the LED 854, and the two modes can be switched and viewed. The mode can be switched by an observer, and can be switched automatically and automatically, for example, after 10 cycles, the light is automatically turned off to prevent battery consumption. good.

The eleventh embodiment will be described with reference to the penlight 750 shown in FIG. The light source uses an LED 774 having a divergence such that the half-valued directivity angle is 70 degrees or more as the directivity, and illuminates around the hologram, but is also applied to the light diffuser 770 disposed in the periphery, and the decorative effect It is rising. The light diffuser 770 has a rough surface with a large surface roughness, and part of the light diffuser 770 is formed with a character 771 in a portion with a small surface roughness. The light diffuser 770 has a thickness of 3 mm, for example, and the hollowed inner wall is mirror-finished, so that the light incident from the inner wall has an internal reflection component and is easy to shine as a whole. The light from the light source 774 is irradiated from the surface of the light diffuser, and there is also light incident on the inside from the inner wall 772, from which the diffusion effect from the light diffuser can be observed simultaneously with the reproduction of the hologram. . Since only one light source illuminates, the amount of light distribution is often used for hologram illumination, and the hologram reproduction image is used at a position that does not interfere with the observation of the hologram reproduction image by using other light effectively. Produces the effect of decorating.

The housing front surface 773 is formed of a curved surface having a curvature. In this case, if there is a difference in curvature between the outside, that is, the observer, the inside, and the hologram side, the image is enlarged or reduced or the image is distorted like a lens effect. When known distortion occurs, it is possible to perform image processing on the recording image data in advance so as to compensate for the distortion before recording the holographic stereogram.

A twelfth embodiment will be described using the hologram illumination device 300 shown in FIGS. The hologram illumination device 300 includes a pen light unit 350 and a mounting unit 310, and is removable.

First, the penlight unit 350 will be described with reference to FIG. The handle portion 360 is formed in a cylindrical shape, and includes a battery 355, a switch 365, an LED lighting circuit (not shown), and a light source LED 374 and the like in the vicinity of the central axis of the cylinder so as to emit along the central axis. The light emitted in the axial direction from the light source LED 374 is converted into parallel light by the lens 377 or light whose parallel degree is adjusted so that it can be efficiently illuminated in a predetermined area at a position separated by a predetermined distance. , And enters the prism sheet 375. The prism sheet is, for example, a transparent optical plastic formed in a saw blade shape with an interval of about 0.01 mm to 1 mm, preferably about 0.1 mm, and can be bent in a predetermined direction depending on the slope angle. In the example of FIG. 29, the light is once bent toward the viewer by the prism sheet, and then bent in the direction away from the viewer by the reflecting mirror 376 to reach the hologram 314. Since the irradiation angle to the hologram is an optimum angle for observing the hologram, a bright image can be observed from near the front of the hologram.

The lens 377, the prism sheet 375, the reflecting mirror 376, and the hologram support portion are attached to a flat spherical housing 360, and the housing 360 and the handle portion are attached by a screw portion (not shown). In the case 360, only the portion 373 for observing the hologram is made transparent, but a portion that is not used for irradiating the hologram because a member that diffuses light inside is applied or disposed adjacent to the portion other than that portion. Or a different light source (not shown) can be applied to produce a decorative effect.

If the light from the light source LED 374 passes through a transmissive member such as the lens 377 and the prism sheet 375 and goes out of the optical opening 373 of the housing as it is, it is too dazzling or the decorativeness deteriorates. 378 is arranged so that even if it is intended to look into the light source section, bright light that is dazzling directly is not visible.

The shielding plate 378 may be decorated with characters and the like. The shielding plate 378 may be made of a diffuser or may partially have an optical aperture, even if it does not completely shield light.

In the present invention, the reason for temporarily deflecting the light source emitted in the cylindrical axis direction of the handle part is that most conventional flashlights, penlights, etc. emit light in the cylindrical axis direction of the handle part. is there. That is, the housing 360 in FIG. 29 can be used as a flashlight if it is removed from a screw portion (not shown), or can be used as a conventional penlight if it is replaced with another cylindrical diffuser as shown in FIG. I can do it. In FIG. 30, the cylindrical diffuser is such that a diffusion sheet 381 is arranged in a cylindrical shape inside a transparent cylindrical plastic 380.

In other words, if the case 360 of the present invention and the necessary optical components, light diffuser, and hologram built therein are arranged in a conventional flashlight or penlight, a hologram observation apparatus can be easily configured. It becomes possible.

When a high-intensity power LED of 1 W or more is used as the light source LED 374, it may be dazzling when entering the human eye without being diffused or shielded. If the replacement as described above is left to the user, the bright light may be seen unexpectedly during the replacement and the eyes may be damaged, so the case 360 in FIG. 29 and the cylindrical plastic 380 in FIG. A switch is attached to the mounting portion so that the interlock mechanism works so as not to emit light when not mounted.

In this example, a prism sheet was used to bend the light emitted in the cylindrical axis direction, and a reflecting mirror was used to bend it again in the hologram direction. A hologram element, an electro-optic modulation element, an acousto-optic modulation element, or the like may be used.

In the penlight 350 alone, the relative relationship between the position and angle of the hologram and the light source is fixed. However, if the entire penlight 350 is placed on the dedicated table or swinging device 310, it can be seen from a stationary observer. You can observe the movement. An example of the pedestal and the swing device will be described with reference to FIG. The pedestal is configured with pivot portions 390 and 391 so that the penlight 350 can rotate with little friction about the central axis of the handle portion or the vicinity of the central axis including the hologram surface. The pivot parts 390 and 391 are connected to the observer of the penlight 350 by a support part 392 on the rear side, and the penlight 350 part can be attached and detached by the elastic force of the support part 392. A portion in contact with the pivot on the penlight 350 side is formed with a small concave portion, the position is fixed, and the contact area is reduced to reduce friction during swinging rotation. The grounding portion 397 is made relatively heavy in the entire lighting device, can be stably held with a low center of gravity, and can be adjusted so that the hologram can be observed from about 5 to 45 degrees above the grounding portion. Weights 393 and 394 are disposed inside the penlight 350 and swing as a rigid pendulum about the rotation axis. Furthermore, the weights 393 and 394 are made of a magnetic material, and electromagnets 395 and 396 including coils are arranged on the supporting part 392 side of the opposing table, and the natural vibration in which the penlight 350 swings as a rigid pendulum. By controlling the current of the electromagnet including the direction at a frequency close to the number, it can be continuously swung. That is, the time period during which current is passed through the electromagnet so that the electromagnet 395 opposing the weight 393 repels, the electromagnet 396 opposing the weight 394 is engaged, or both, and vice versa. When the opposing electromagnet 395 is attracted, the electromagnet 396 opposing the weight 394 is repelled, or when both are repeatedly controlled so that the time period in which the current flows through the electromagnet is alternately generated, Such continuous swinging can be realized.

As a movement using an electromagnet, as a platform application to show the figure by rotating, a mechanism that rotates at a constant speed in one direction by solar cells or dry batteries, or AC drive, and rotates at a constant speed in the opposite direction when pressed by hand There is. Examples of products include “Battery Type Turntable” sold by Platz and MM Koubou. An example of this mechanism will be described with reference to FIG. (A) is a figure when the rotary table 1301 and the electromagnetic movement mechanism main body 1302 are separated from each other. When combined, the arrangement is as shown in (b). Normally, once it starts to rotate, it continues to rotate in the same direction. When force is applied from the outside, it will rotate in the opposite direction. In the present invention, in order to convert this mechanism into a swing mechanism within a certain range, a stopper is provided in the range of the viewing angle of the hologram. That is, as shown in FIG. 53 (a), a plurality of positioning holes are formed in the 1303 stopper support, and the stoppers a1305 and b1306 are fitted into arbitrary two of them. The rotary shaft 1308 is fitted to the electromagnetic movement mechanism so that the protrusion on the back side of the rotary table 1301 is between the two stoppers. By doing so, the constant speed rotation mechanism could be changed to a swing mechanism without any change to the electric circuit. In addition, since the stopper can be selected from a plurality of positions, the swing range can be adjusted to the best angle according to the position of the observer. Both the stopper and / or the protrusion may be formed of a rigid body, but an elastic body such as rubber or sponge is used. By doing so, there is an advantage that the force that gives the initial speed for reversing is not generated and stopped, and the impact sound hitting the stopper can be reduced, which is very effective. Although the example in which the user selects two of the plurality of holes of the stopper support 1303 has been described, the stopper position may be automatically controlled by electric control, air control, or the like. Further, the stopper movable position may be moved at the time of swinging so that the swing movable range changes every time.

A configuration example using this movement will be described with reference to FIG. In the display 1310, the hologram mount 1312 with the hologram 1311 attached is placed on a swinging rotary table 1301. The hologram 1311 on the rotary table 1301 is illuminated from the LED 1313 attached to the tip of the LED support 1314 supported by a stationary member, whether or not adjacent to the movement mechanism main body 1302. The stationary light source and the oscillating hologram make it possible to observe a moving image even from a stationary observer.

As another example, the display 1320 will be described with reference to FIG. An LED support 1314 is fixed to the turntable 1301, and the LED 1313 attached to the tip is oriented obliquely upward. A hologram support 1315 fixed to a part of the movement mechanism main body 1302 holds the hologram 1311 and the hologram mount 1312. By moving the light source and fixing the hologram, a moving image can be reproduced from a stationary observer.

As a modification of the display 1320, a display 1330 will be described with reference to FIG. The glass 1312 to which the hologram 1312 is attached is held facing upward slightly assuming that it is placed on a table. A movement mechanism having a rotation axis that is a straight line passing through the approximate center of the hologram is arranged on the opposite side of the hologram observer. An LED support is used as a rocking member instead of the rotary table, and the LED is irradiated from the front side and the lower side of the hologram toward the hologram. In order to balance the swinging portion, a balancer 1324 is disposed on the side opposite to the LED. The balancer may also serve as a functional component such as a battery or a circuit.

As described so far, the display 1310 is a type in which the light source is fixed and the hologram swings, and the displays 1320 and 1330 are types in which the hologram is fixed and the light source swings. Both the hologram and the light source may be mounted on the swing mechanism. Thus, various variations are possible in order to make a moving image visible even when the observer is stationary.

  Although the swing mechanism has been described as using an electromagnet, a mechanism for transmitting the motor by a gear or a belt may be created to reverse the motor forward and backward. Further, by transmitting from the motor via an eccentric cam or a link mechanism, the motor can be repeatedly swung even if it rotates in one direction at a constant speed. Various driving methods for the motor and electromagnet can be selected such as supply from a household AC outlet power supply, supply from a battery, supply from a solar battery, and the like.

It is also possible to use a spring or spring having the elastic force as a drive source without using electric drive. Further, it is possible to use only gravity and swing it like a mess. The thirteenth example will be described with reference to FIG. The hologram illumination device 200 includes a penlight unit 210 including a hologram 214 and a penlight holding unit 220 having a swinging mechanism for placing the penlight unit 210. The penlight holding unit 220 is connected to the support unit 225 via bearings 223 and 224 and can rotate, and weights 221 and 222 are arranged so that the center of gravity is slightly below the center of gravity of the rotation axis. Yes. By this mechanism, when the penlight is housed in the holding portion, it reciprocates at a slow speed.

As described above, in the example of the structure in which the penlight unit and the pedestal can be separated, at the stage where the penlight unit is set on the pedestal, the switch is turned on and the lamp is turned on for a predetermined time or shaken for a predetermined time. You may make it do. Further, in the swinging device by gravity, the swinging may be started by applying an initial motion with a human hand, and the light is turned on until it stops, and when the swinging stops, it may be turned off naturally. This control is performed by installing a photoelectric detector and checking whether the photoelectric detector is cut off by a swinging operation. Moreover, the rechargeable battery may be built in the penlight unit, and the rechargeable battery may be charged when it is set on the table.

A fourteenth embodiment will be described using the hologram illumination device 250 of FIG. The hologram 251 is attached to the surface of a glass plate 252 having a thickness of about 10 mm to 100 mm. The glass plate 252 is attached to the casing 262 so that when the casing is placed on a desk or the like, the hologram is directed upward from 0 to 45 degrees so that the hologram can be easily seen from the front. This angle is preferably adjustable. The hologram is irradiated from various angles from the LED 255 built in the same casing. In addition to irradiation from a plurality of LEDs, one LED may be swung using electromagnetic force, gravity, elastic force, or the like.

On the other hand, light from the red, green, and blue LEDs 256, 257, and 258 enters the glass from the end of the glass plate 252. If the glass plate is cut and polished at various angles called diamond cuts, or has a 3D laser engraved inside, the decorative effect of the LEDs 256, 257, and 258 increases.

The hologram may be affixed to the observer side of the glass plate, may be affixed to the opposite side of the observer, or may be arranged so as to be sandwiched between a plurality of glass plates. As described above, a plurality of holograms may be arranged at a plurality of positions. Different light sources are arranged at different positions, they are turned on sequentially, and when illuminating the first hologram, the background light diffuser illuminates in blue, and when illuminating the second hologram The background light diffuser illuminates in red, and can give different decorations and effects in time series.

When the hologram is pasted on the side opposite to the viewer of the glass plate, a ground glass-like acrylic material 254 is further arranged in the back. The surface of this acrylic material is decorated by laser processing, and when irradiated with light, the processed portion is emphasized and shines. The acrylic material 254 is irradiated by red, green, and blue LEDs 259, 260, and 261 built in the casing 262. In this way, it is possible to improve the decorativeness of the hologram by irradiating light from the inside or the outside of the substrate on which the hologram is attached.

A clock 253 is embedded in a part of the glass plate 252. Not only the analog timepiece as shown in the figure, but also a digital display timepiece, thermometer, hygrometer, calendar, photo display, liquid crystal display, etc., some of them may be arranged.

The glass plate 252 may not be glass but may be a resin material such as acrylic, polycarbonate, polystyrene, or the above-described material containing a fluorescent material.

As described in all the first to fourteenth embodiments, the light source incident on the light diffuser and the light source for hologram illumination may be the same or different. . Even in another case, in order to reduce the power consumption after sharing the power supply portion such as a battery, the balance of the amount of power supplied to the light source is changed between hologram illumination and non-illumination.

If the light that illuminates the light diffuser is too strong, the hologram image does not stand out. Therefore, the light that illuminates the light diffuser is weakened only when observing the hologram. That is, when the switch is turned on, first, the light diffuser shines brightly at different timings in order for each of the red, green, and blue LEDs to illuminate with various colors and brightness, and then illuminate the hologram One white LED is turned on first, then a plurality of LEDs that illuminate the hologram are sequentially turned on, and then the LED of the holographic illumination slowly darkens, and some red, green, and blue LEDs that illuminate the light diffuser Lighting effects that change with time may be applied, such as brightening and turning off all LEDs.

In the above-described embodiment, the case where the predetermined angle of the apparatus according to the optimum illumination angle of the hologram is 45 ° is given as an example. That is, in the state of illuminating the hologram support, the angle formed by the line connecting the light source and the center of the hologram or holographic stereogram and the normal of the surface of the hologram or holographic stereogram is the observer. However, the present invention is not limited to this. Preferably, the above-mentioned angle is supported so as to maintain a specific angle between 40 degrees and 70 degrees above or between 40 degrees and 70 degrees below. If the angle is less than 40 degrees, the light source tends to enter the eyes during observation, which is not preferable. This is because when the angle is greater than 70 degrees, a compact illumination device is obtained, while surface reflection on the hologram surface increases, making it difficult to view the hologram image brightly.

In the above embodiment, the light from the light source is dazzled when it reaches the viewer's eyes without being blocked, absorbed or diffused, and obstructs the observation. A diffuser or a combination of them is arranged.

The fifteenth embodiment will be described with reference to FIG. The penlight 400 includes a hand-held portion 410 and a transparent cylinder 420 that is screwed and fixed to the hand-held portion. The handheld unit 410 includes a battery (not shown), a light source such as an LED arranged so as to emit light in the direction of the cylindrical axis, a light emission control circuit, and a switch. A female screw similar to the cap part of a plastic bottle beverage is formed in the portion fitted with the cylinder 420, and it is removed by rotating and inserting the cylinder 420 with a male screw having a pitch corresponding thereto. It is possible and can be fixed firmly.

A light diffusion sheet 430 and the like are inserted into the inside of the cylinder 420 and close to the hand-held part, and a cap 440 that can be inserted and fixed from the front-end part is disposed at the tip part far from the hand-held part. As shown in FIG. 36, the cap 440 includes 440-a and 440-b, and slots 450 and 460 are provided between these two parts. A circular mirror 455 is inserted into the slot 450, and a hologram 465 is inserted into the slot 460, and they are fixed by combining 440-a and 440-b. The hologram 465 has a rectangular shape. Of the four corners, three are R1 mm and only one is C2 mm, and the slot 460 is formed in a corresponding shape. Attempting to insert into the lens does not allow the R1 mm hologram medium to fit in the corner of the cap side C2 mm.

The light diffusing sheet 430 may be inserted after being individually printed in the final process of assembly using a milky white translucent material having an ink receiving layer or a thermosensitive coloring layer on one side. . By doing so, the hologram 465 can be customized with the light diffusion sheet even if it is the same mass-produced famous characters and company logos, so the value as a souvenir increases. Landmarks and theme park characters are holograms, and it is possible to combine a photograph taken on a spot of a tourist attraction or an event with an ink jet printer or the like on a diffusion sheet. Moreover, it is possible to put a corporate advertisement etc. in this light diffusion sheet. In the milky white material of the light diffusion sheet, the image receiving layer may be formed on the front side or the back side. In particular, in the case of the back surface printing type, the smoothness of the surface of the base material is too good, and it may stick to the inner surface of the cylinder, resulting in poor handling. Therefore, if the surface of the base material is slightly roughened to make the matte surface, the surface roughness of the cylindrical inner surface is reduced, or fine particles are interposed between the surfaces, the surfaces will stick together and the position will be corrected. Avoid situations where you can't. As the layer structure of the light diffusion sheet, an ink receiving layer containing a polymer resin such as urethane, acrylic, polyester or polyurethane is formed on the base material with a thickness of 1 μm or more, and has a quick drying property. Therefore, high-speed processing is possible even when on-demand inkjet printing is performed.

If the penlight hand-held part 410 has a battery part, a switch, a decorative logo printed part, etc., the hologram observation window is behind the battery cover, the decorative logo-printed part or switch is in the rotation direction of the hand-held part 410. It is important to fix it so that it is on the side of a certain part. For this reason, the character, the photograph, etc. recorded on the observation window or the light diffusion sheet are shaped so as to be positioned so as to be aligned with the front surface of the hand-held portion in the rotation direction when completed. That is, the screwed portion of the hand-held portion has a protrusion, and the transparent cylindrical portion has a concave portion, and has a structure that stops when screwed. In addition, the light diffusion sheet 430 is arranged in the circumferential direction inside the transparent cylinder. Are marked with a positioning shape and target so that the position is determined.

In addition, since there is a possibility that the hologram medium is observed alone, the recommended observation conditions as shown in FIG. 14 are printed as symbol marks. The symbol mark makes it easy for people who speak different languages from around the world to understand intuitively regardless of gender.

With the mirror 455 and the hologram 465 attached, and the caps 440-a and 440-b combined, as shown in FIG. 37, the hole 421 is inserted into the cylinder 420 and processed into the cylinder 420. If the screw hole pilot holes 441 processed in the cap 440 are combined and fixed with screws, each part will not come off even if the entire penlight is swung. The fixing method of the cylinder 420 and the cap 440 can be fixed by fitting screws formed on the entire circumference of the joint between the cylinder 420 and the cap 440 without fixing with screws, A structure that is locked by turning in the direction may be formed and fixed.

The cap 440 is formed so that an opening is formed when the cap 440-a and 440-b are combined. The light reflected at a predetermined angle by the reflecting mirror 455 is illuminated on the hologram 465 so that the hologram 465 can be observed through the cylinder 420.

The cylinder 420 may be provided with an opening for holographic observation. In that case, image distortion due to the cylinder does not occur, but there is a disadvantage that foreign matter enters inside through the opening, so that light passes through acrylic, polyethylene. By increasing the flatness with a colorless and transparent material such as terephthalate, polycarbonate, and glass, an image is reproduced with little image distortion.

Since the inner and outer surfaces of the cylinder 420 have curvature, a lens effect is produced. However, if these curvatures are known and the position where the hologram is fixed is also known, an image recorded as a hologram is previously processed by image processing or the like. It is also possible to compensate.

A hard coat can be applied to the opening so as not to be scratched.

As shown in FIG. 38, the portion of the cap 440 to which the hologram is fixed can also be open on the side opposite the observer. In that case, if the base material of the hologram is transparent, when the light source is not turned on, the other side of the cylinder can be seen through, and when the light source is turned on, it is possible to produce an effect that the image emerges from the transparent portion. .

When the light source incorporated in the hologram handheld unit 410 is a high-luminance type such as a 3W-LED, the user feels dazzling when a large amount of light hits human eyes without being diffused or absorbed. Therefore, a diffusing member and an absorbing member are arranged so that the light from the light source does not leak outside from the penlight part without being diffused in an area of 5 mm square or more, for example. For example, as described in the sixth embodiment, an anisotropic absorber such as a louver film and an anisotropic diffuser such as Lumisty are observed not only on the opposite side to the observer of the hologram, but also It was also arranged on the optical opening on the user side. Since the optical opening on the viewer side also serves as a window for observing the hologram, the image quality of the hologram should not be deteriorated in the observation region. For this reason, in the observation angle area | region, it comprised with the material used as the total light transmittance of 60% or more and haze value 20 or less, desirably the total light transmittance of 80% or more and haze value 10 or less.

38 and 39 show examples in which these optical openings are kept as simple transparent resin or glass material and non-diffuse light is prevented from being emitted from the openings by a shield or a diffuser. That is, in the penlight 401, a shielding member 469 is provided on the light source side of the cap portion 440 to provide an aperture function, and the opening is limited to the size necessary for hologram irradiation and shielded. Geometrically determined by ray tracing connecting the size of the light source 471, the directivity control lens 472, and the irradiation area of the hologram 465. This also has the effect of preventing scattered light from irradiating the light diffuser or light diffusion sheet near the hand-held part of the cylinder without contributing to the illumination of the hologram to reach the hologram, thereby reproducing a good hologram image with high contrast. Can be made.

Up to this point, an example has been described in which the hologram is held in a flat shape, but if the hologram is held in a cylindrical shape and image processing is performed accordingly, the subject appears to be floating in the cylinder. Will also be possible.

As an example, an example of a penlight 406 called an ALCOVE type in which a hologram material is arranged along a part of the inner periphery of a cylinder will be described with reference to FIG. That is, the basic structure is the same as that described with reference to FIG. 35, but the hologram is not set as a flat surface but is bent and set along the inside of the cylindrical member cap 440 to be formed. Since the total thickness including the base material of the hologram material is designed to be about 100 to 400 μm, it can be held and fixed only by the stiffness of the film between the claw structures 467 arranged inside the cap 440. In the example shown in the figure, the hologram material is arranged over approximately 180 degrees, that is, a half circumference. However, if the viewing angle can be secured, this angle is not necessary. Light from the light source is reflected by a reflecting mirror formed by a part of a conical shape provided inside the cap, and irradiates the hologram at a predetermined angle. Since there is an opening 492 provided in the shielding member 469, only light that contributes to illuminating the hologram passes through the opening, is reflected by the conical mirror, and reaches the hologram. Therefore, it does not come out of the optical opening that is the window. In addition, since the light reflected and scattered by the diffusion sheet 430 does not reach the hologram, the reproduced image is not deteriorated and can be observed well.

As another example, 407 applied to an edge-lit transmission multiplex hologram will be described with reference to FIG. The hologram is index-matched and bonded together so that air does not enter the outer periphery of the acrylic cylinder. The illumination light passes through the inside of the acrylic cylinder through the opening, is reflected by the conical mirror 456 disposed on the opposite side, and reaches the hologram. Since this illumination light angle is not less than a so-called critical angle, it does not come out from the surface in the observation direction, and the user does not feel dazzling. In addition, since the opening 492 is provided in the shielding member 469, light that contributes to the hologram can be separated from light that does not contribute, so that a hologram image with high sharpness and high contrast can be reproduced.

In both the penlight 406 example and the 407 example, since the hologram material has a curvature, it is possible to display the image with a natural stereoscopic effect by correcting the image distortion by performing image processing in advance on the assumption of the known curvature. It becomes.

Note that a diaphragm or a collimation lens may be provided in the immediate vicinity of the LED 471 or the adjacent lens 472. By doing this, it is possible to reproduce a hologram image with high sharpness by increasing parallel light, or to reproduce a bright hologram image by increasing the amount of light that passes through the opening 492.

In addition, when the reflected illumination light from the reflecting mirror 455 leaks out from the opening on the back, it is light that returns in the direction of the hand-held part, so in general it is often blocked by the observer. A shielding member 470 is also provided outside the cylinder. The shielding member does not necessarily need to be opaque, and may be a member having a total light transmittance of about 50% or a diffusive member. Another example in which a light shielding member is provided outside the cylinder will be described with reference to FIG. By increasing the outer diameter of the decorative collars 432 and 433, it is impossible to physically look into the light source inside the handheld portion from the opening. That is, even if the light emitted from the light source goes out of the opening as direct light or reflected light, these colors 432 and 433 serve as light shielding plates and do not reach the human eyes unintentionally. . The collars 432 and 433 and the shielding member 470 provided outside the cylinder are not only for the purpose of shielding, but also serve as a hinge member for a stand or a strap attachment member for allowing a penlight to be viewed on a desk or the like. good.

In order to prevent light from leaking outside, an example 403 using a polarizing plate will be described with reference to FIG. Light emitted from a light source 471 such as an LED passes through the directivity angle control lens 472, and then passes through the first polarizing plate 480, so that light having a uniform polarization component is irradiated to the hologram and contributes to observation. Thereafter, if the hologram substrate is transparent, the light is emitted from the opening on the rear side with respect to the observer. If a second polarizing plate 481 is arranged in front of the hologram substrate, the arrangement angle is appropriately considered. By doing so, the outgoing light to the outside can be suppressed. In the case where a light source having a uniform polarization plane such as a laser is used instead of an LED, the first polarizing plate can be dispensed with.

A through hole that attaches a strap or is hooked to a hook may be provided at the tip of the cap portion 440. By doing so, there is an advantage that it is easy to display products without reversing the top and bottom with simple packaging.

The penlight may be configured to accommodate a plurality of holograms and a plurality of cap portions. An observer can view a plurality of hologram images by replacing them.

The penlight may have a single hand-held portion or a plurality of cylindrical portions at the tip. FIG. 42 shows an example 404 of a penlight having three cylindrical portions, each having a hologram and its illumination light source. The opening faces outward so that it is not obstructed by other cylinders. In the example in which two cylindrical portions are arranged, they may face in the same direction so that two holograms can be viewed simultaneously. Each is provided with a light source and may be turned on or off sequentially or simultaneously by the same control circuit. Further, only one light source may be provided, and the light source may be held after being rotated by the viewer's intention.

In the embodiment described in the penlights 401 to 404, for the observer, the light source is observed below the hologram, but when viewed as a single hologram, the light reflected from the mirror is irradiated obliquely from above. When the recommended reference light angle of the hologram itself is 57 °, a symbol mark as shown in FIG. 46A is printed, and the penlights 401 to 404 are also arranged on the back of the handle part or a part of the cap part. A small and similar symbol mark of FIG. 46 (a) is formed. Therefore, when the hologram and its reproduction penlight main body exist in a separated state and the hologram is replaced, for example, there is a hologram printed with a symbol mark as shown in FIG. Thus, the user can know in advance that viewing is not possible even if worn. In such a situation where there is no symbol mark, it would be a situation that would not be understood unless it was put on, and this was a source of confusion.

Up to this point, we have focused on an example in which light from a light source is reflected by a reflector placed at the tip of a penlight cylinder, and a hologram having a surface arranged so as to be substantially parallel to the cylinder axis is irradiated. However, the hologram surface and the cylindrical axis are not necessarily parallel to each other, and may be arranged so as to be seen from slightly below or above. An example of the penlight 405 that is viewed from the handheld portion side without the mirror at the tip of the cylinder will be described with reference to FIGS. 43A and 43B. 43A, the cap 442 inserted at the tip of the transparent cylinder 420 is formed with a surface obtained by obliquely cutting a cylinder with the cylindrical axis as the center as shown in FIG. A hologram is affixed or closely fixed to the surface. When the cylindrical axis and the hologram surface are fixed at an angle of A °, a hologram made on the assumption that it is illuminated downward (90-A °) from the observer is reproduced under the best conditions. It is possible. For example, if A = 32, the image is reproduced at the center of the normal direction of the hologram when illuminated from an angle with an opening of 58 degrees with respect to the normal of the hologram surface. Inside the cylinder, a diffusion sheet is arranged so as to diffuse light that does not contribute to hologram reproduction over almost the entire circumference, but it penetrates into a circular shape as much as the viewing zone where the hologram can be observed, and the optical opening 431 is formed. Formed.

The penlight 405 is formed with a symbol mark as shown in FIG. This is because the hologram reproduction-only device is such that when viewed as a single hologram, it appears correctly when irradiated from a lower oblique angle of 58 °. At first glance, both penlights 403 and 405 are devices that irradiate the light source from below the observer, but the conditions required for the hologram to be mounted are completely different. It is very useful to describe in both the medium and the playback device. In particular, in the case of a hologram whose base material is transparent, the original irradiation direction will shine even if the medium is placed upside down, but the reproduced image will be the reverse of the depth and the front, It is much more confusing than regular prints. By describing the symbol mark common to the hologram medium and the reproducing apparatus, confusion can be eliminated.

When the hologram is arranged at an angle like the penlight 405, a diffraction image is formed and observed in the direction of 490 in the figure, but at the same time, the light reaching the hologram without diffusing from the light source is reflected in the regular reflection direction 491 on the hologram medium surface. Causes surface reflection. If this surface reflection goes out of the opening, it may be too dazzling, so an antireflection film may be formed on the hologram medium surface or a moth-eye structure may be used. Further, by providing an optically anisotropic absorber or optically anisotropic diffuser in the opening, it is possible to increase the transmittance in the observation direction 490 and to shield or diffuse in the 491 direction of regular reflection. . As the optical anisotropic absorber, for example, a louver film whose opening angle is offset may be used.

As for the penlights exemplified in the penlights 400 to 405, a commercially available penlight, a flashlight, or the like can be used as it is only for a hand-held portion. That is, an opening for irradiating illumination light, an optical opening for observing a hologram, and a hologram of a hand-held portion having a battery including a rechargeable battery, a light source such as an LED, a switch, and an electric control circuit. If a hologram medium is provided that has a diffusing member that transmits and diffuses a portion of light that does not contribute to illumination, in addition to the functions of penlights and flashlights up to that point, it is possible to add a function that allows easy observation of holograms. it can.

When a reflecting mirror is further added to the hologram medium described above, the degree of freedom in product design as an illuminating device can be applied to illumination light with a low degree of freedom, as commercially available penlights can only emit in the direction of the cylindrical axis of the handheld part. Can be greatly improved. This is because the hologram has an illumination angle predetermined at the time of manufacture and cannot be observed unless it is irradiated from that direction. As a hologram medium, the illumination light incident part, the observation opening part, the reflecting mirror, etc. are integrated, so that even a person who does not have basic knowledge of holograms can definitely observe in a good state.

As an example of the sixteenth embodiment, an example in which an audio reproduction mechanism is incorporated will be described using the box-type hologram reproduction apparatus 1000 shown in FIG. When the lid portion 1001 is opened, the LED built in the main body 1003 is irradiated obliquely downward from a predetermined angle when the lid portion 1001 is opened. The main body incorporates an audio data storage device, an audio data amplification circuit, a speaker 1004, a battery 1006, an LED, an electronic circuit board 1007, and the like. A micro switch 1005 is arranged at a position where the main body is not conspicuous. When the lid is closed, the switch is pressed, and so-called power is turned off. When the lid is opened, the power is turned on by moving the switch to the open position. The lid 1001 is fixed at a predetermined angle, for example, 115 ° by a stopper (not shown). A plurality of, for example, seven, LEDs are arranged in advance at different positions. By sequentially lighting the LEDs, it is possible to make it appear as if the hologram image is moving to a stationary observer. The positional relationship between the LED and the hologram is such that a central LED, L4 is arranged in an angle α, for example, 58 ° with respect to the normal from the center of the hologram, and a line connecting the center of the hologram and the central LED, L4. L1 to L3 and L5 to L7 are arranged so as to look at the center of the hologram at a different angle in the vicinity on the surface including.

Since the lid 1001 includes a symbol mark 1008 indicating a reproduction condition of a suitable hologram, even when the hologram 1002 is replaced with another image and attached or pasted, the hologram cannot be observed without being adapted. Such a thing cannot happen.

The control after the power is turned on can have various variations. For example, after all the LEDs are turned off, the holograms are turned on in turn by L1, L2, L3, L4, L5, L6, and L7. On the other hand, the frame of the hologram image of the recorded image is reproduced in the order of L1 to L7 in FIG. As the image source of the holographic stereogram, as used parallax image sequence taken with relative movement of the object in one video camera, a few seconds at the time of shooting, for example, a person waving issues a message "Hello" Suppose that it is a parallax image sequence in which a scene is recorded. When a holographic stereogram created from this series of parallax images is illuminated with a fixed light source, the observer moves left and right to play an image of waving his hand by moving his mouth, but the playback speed is observed. It is difficult to synchronize because it depends on how the person moves. In the present invention, when light sources such as a plurality of LEDs are sequentially turned on, or when one light source moves smoothly relative to the hologram, the lighting control speed is set to the sound reproduction speed at the time of shooting. By synchronizing, it is possible to reproduce a moving image in accordance with the sound as if a person is making a sound.

Although an example in which continuous images are synchronized has been described, a more effective display can be configured when discrete images are input. Examples thereof will be described with reference to FIGS. Under the premise that the holographic stereogram is observed from the normal direction of the center, only when illuminated from L1, an image including a character representation of a word synchronized with a certain lyrics is reproduced as a hologram. When the light source is turned on, a continuous stereoscopic image is reproduced. When music is played from the sound playback device built in the lighting device, L2 to L7 are sequentially turned on and off, and when the rust of the song is reached, if only L1 is lit, an effective presentation effect can be obtained. .

As another example, a holographic metronome can be constructed. That is, if the parallax image with the conductor's movement is made into a holographic stereogram and the LED lights are turned on sequentially in synchronization with the click sound, the click sound of the beat with the movement and timing of the conductor can be heard. It will be. For the sake of simplicity, suppose that there is a four-time metronome produced by a holographic stereogram of the motion of a conductor of 16 parallax images. Sixteen LEDs are arranged on the left and right sides, which are L1 to L16, respectively. When L1 to L16 are sequentially turned on at equal time intervals, control is performed so that a click sound is generated at the timing when L1, 5, 9, and 13 shine.

The same effect can be obtained if light emission is controlled in synchronism with the movement even when one LED is moved relative to the hologram instead of arranging a large number of LEDs. Rather, when 100 or more parallax images are included, the motion of the image is smoother and the visual effect is improved.

In the case of synchronously controlling the light emission of the light source and the timing of the sound, it is necessary to strictly adjust if the observer's viewpoint changes. For example, if the timing of the sound is controlled assuming that it is observed from the normal direction of the hologram, and the observer has shifted to the left or right, a sound will sound earlier than the image, The opposite is true. In order to make this adjustment, the position information of the observer's eyes is detected by a position detection device, and the sound reproduction timing is advanced or delayed. Detection of the position information of the observer's eyes is performed by image processing based on the captured image with an imaging device mounted on the device side, but can be applied if other methods can be detected. Further, an input device such as a volume (not shown) is mounted on the reproduction apparatus main body, and the observer himself may adjust it.

As a seventeenth embodiment, an example of a crystal glass figurine will be described using a desktop lighting device 1100 shown in FIGS. The glass 1101 with the hologram 1102 attached to the surface has a structure that can be placed on a table or the like by a glass support 1108. Below the observer side of the hologram, fifteen LEDs 1104 for illuminating the hologram in a predetermined manner are held in a circular arc in two rows so that each of the LEDs 1104 faces almost the center of the hologram. This is because the hologram is fixed to the flexible substrate 1109 by soldering, and the flexible substrate is fitted into the slits formed in the two LED substrate holders, so that it can be fixed with high accuracy and easily. Yes. The reason why the LEDs are arranged in two rows is to increase the reproduction luminance of the hologram. Normally, when a hologram is illuminated simultaneously with multiple light sources, the reconstructed images overlap each other and blur in a multiple image, but for holographic stereogram illumination with parallax in the horizontal direction, it is necessary to arrange it in a direction orthogonal to the parallax. It will not be a multiple image. Since it can contribute to increasing the luminance without degrading the image quality, it is effective to simultaneously illuminate in two or more rows as in this example. On the side opposite to the viewer of the glass, a translucent acrylic plate is arranged as a back decorative plate, and the decoration effect illumination is performed by the back decorative plate illumination 1106 arranged inside the glass support 1108. The

As an eighteenth embodiment, a pachinko gaming machine 1200 as shown in FIG. 52 will be described. The pachinko gaming machine 1200 includes a game board 1101 in which a number of nails (not shown) are implanted, and the opening on the front surface is covered with a glass plate 1203. In the center of the game board 1201, there is provided a display device 1204 using liquid crystal or the like for displaying variable image information such as numbers and marks related to the game of the pachinko machine. A transparent substrate hologram is arranged in front of the liquid crystal display device 1204, that is, on the player side, and is a light-emitting diode installed at a predetermined position, for example, when the game is in a “hit” state. When the (LED) 1205 irradiates the hologram, a three-dimensional image emerges from the recorded hologram. The predetermined position may be obliquely above, but there are many amusement hall lighting etc. above, and in order to avoid unintentional hologram images being reproduced by the illumination light from here, in this case from the observer's line of sight Has a hologram to be irradiated from below. Preferably, a specific angle between 40 degrees and 80 degrees below the observer is maintained.

If the substrate is transparent, the stereoscopic effect will appear as if there was nothing, so the production effect will increase. Although the game board 1201 does not irradiate the hologram but has an LED 1206 for illuminating the diffuser in order to produce a staging effect, it only illuminates the diffuser and does not illuminate the hologram. Therefore, only an image having an intensity of 1/10 or less is reproduced compared to the diffracted light intensity of the hologram when the hologram is illuminated and reproduced.

The hologram image is reproduced by illumination. However, when the substrate is transparent or the background is bright, the contrast of the hologram is remarkably deteriorated. This is because even if the hologram image is black, if the white liquid crystal display shines white, the hologram image is buried. Therefore, the hologram image is not actively reproduced, and the first state in which only the liquid crystal display device 1204 is viewed is switched to the second state in which the hologram image is actively reproduced. The image displayed on the liquid crystal display device 1204 is changed between the state and the second state. In the second state in which the hologram image is reproduced with good contrast, the display content of the liquid crystal display device serving as the background is darkened or a complementary color is displayed. Desirably, when displaying a hologram image, it is assumed that there is an observer's eyes in the normal direction of the game board from approximately the center of the game board, and the liquid crystal which is behind the region connecting the position of the eyes and the hologram surface The display portion was suppressed to a luminance of 1/3 or less of the maximum luminance. The liquid crystal display device displays cyan on the background of the portion where the hologram image is displaying red, magenta on the background of the portion displaying green, and yellow on the background of the portion displaying blue. Since the hologram image looked clear, there is an effect of displaying the complementary color on the background.

Even if the base material of the hologram medium is transparent, if the sensitizer dye of the hologram recording material remains, some coloring may remain. In the case of a Lippmann-type hologram, the hologram image is not diffracted unless illuminated from a predetermined angle. However, since interference fringes are formed, some non-uniformity and turbidity of the material may be seen. The concern of degrading the display image quality of the liquid crystal display device in the state cannot be wiped out. Therefore, in the first state, the hologram medium itself is moved to a portion other than the front surface of the liquid crystal display device 1204. In the example of the pachinko gaming machine 1200, the hologram medium is supported on a colorless and transparent long film, held in a state of being stretched between rollers 1209 spaced apart with the liquid crystal display device 1204 interposed therebetween, and the first In the display state, the hologram medium is moved to a position away from the front surface of the liquid crystal display device, and the hologram medium is moved to the front surface of the liquid crystal display device only in the second hologram reproduction state.

In addition, as a means for moving the hologram to a visible position in the game table in the second state after concealing the hologram in an invisible position in the first state, it is a winding mechanism between the rollers as described above. For example, the hologram is formed in a plate shape of about 1 mm to 5 mm, and only in the first state, the plate itself is stored in an inconspicuous position such as the back of the game board by an actuator. May be.

If the hologram and the light source move relatively, the observer will see the hologram image move, but if there is an actuator that moves the plate-shaped hologram as described above, the effect can be achieved by moving the hologram while illuminating the hologram. Can be increased.

Further, since it can be assumed that a pachinko player observes from a substantially fixed position, it is easy to synchronize with reproduction of audio information or to synchronize video displayed on a liquid crystal display device.

Observation from the front of the liquid crystal display device 1204 is not hindered, and a louver is applied so that the light beam connecting the hologram and its illumination light source 1205 does not reach the surface of the liquid crystal display device 1204 in the second state in which the hologram 1202 is irradiated. An optical component having a structure is disposed between the hologram and the liquid crystal display device. As a result, the liquid crystal display device does not become difficult to shine due to the illumination for the hologram.
