Description

Technical Field

[0001] The present invention relates to a photo frame having a plate and a holder, the plate defining a plane for receiving a photograph, and the holder being mounted on the plate to hold the photograph in accordance with the plane. Background Technology

[0002] For example, as disclosed in Patent Documents 1 and 2, a structure is proposed that associates fragrance with a photograph decorated in a frame. In Patent Document 1, the fragrance is contained in a container. The container is assembled in a window in a back panel that passes through the frame. The aroma components of the fragrance diffuse from the small hole in the container. In Patent Document 2, a thin sheet of fragrance is inserted into the frame. The fragrance has a thin sheet of absorbent material containing the fragrance components sandwiched in thick paper. The surface of the thick paper is covered with a barrier film of vinyl chloride film. When replenishing the fragrance components, the fragrance is removed from the frame. The fragrance is immersed in a solution of the fragrance components.

[0008] The problem that the invention aims to solve

[0009] At this point, if the viewer could choose different scents based on their current mood, the photograph would further enhance the viewing experience. In Patent Document 1, the frame opens around a hinge when changing the fragrance. The container is then removed from the back panel. The fragrance can be changed based on the opening and closing of the container. This requires more complex work to achieve such a subtle pleasure as changing the scent. In Patent Document 2, the entire fragrance body (=absorbent material + thick paper + vinyl chloride film) is replaced when changing the scent. The new fragrance body is immersed in a solution of different fragrance components. This also requires more complex work to achieve such a subtle pleasure as changing the scent.

[0010] The purpose of this invention is to provide a fragrance-diffusing photo frame that can easily switch fragrances.

[0011] Methods for solving problems

[0012] According to one aspect of the present invention, a photo frame is provided, comprising: a strip of paper containing a fragrance component; a board having a first plane for receiving a photograph on one or both sides, and a second plane for receiving the paper on the back side; a first retainer mounted on the board for holding the photograph in accordance with the first plane; and a second retainer mounted on the board in a detachable manner for holding the paper in accordance with the second plane.

[0013] When the second holder is removed from the board, the paper can be separated from the board as individual units. The paper itself is the absorber of the fragrance components, so the fragrance components only need to permeate into the paper. For example, the fragrance components can be blown onto the paper, similar to how perfume is applied. The fragrance components can be replenished effortlessly in a short time. Furthermore, the scent can be easily switched to other scents by replacing the individual paper units. Different fragrance components can be blown onto new paper units, similar to how perfume is applied. Moreover, since the photograph and the paper are held on the first and second planes respectively, the paper is configured to be separate from the photograph. Contact between the photograph and the paper is effectively prevented. Fragrance components are prevented from seeping from the paper into the photograph.

[0014] The board material can be any resin board with a first plane and a second plane defined on the back side and having a transparent area that at least covers the image of the photograph. An observer can view the image of the photograph through the transparent area. The board material protects the image of the photograph while ensuring visual confirmability. Here, when the second holder is removed, the first holder can remain on the board. When the paper is replaced, the photograph can continue to be held directly on the board. Positional shift of the photograph can be avoided when replacing the paper.

[0015] The second holder is simply a slider guided by a pair of guide rails extending linearly parallel to both sides of the second plane, and displaced between a first position holding the paper in accordance with the second plane and a second position detached from the second plane. The guide rails are disposed on the back of the board, thus maintaining a smooth surface. This ensures good visual clarity of the image. The paper can be removed from the board based on the displacement of the second holder. Here, the second holder can be formed facing outwards, on the same side as the guide rails. This allows adjustment of the shape of the back side within the board.

[0016] The sheet material can be made of any transparent material, as long as an opaque film is formed on the surface of the sheet material to at least cover the edges of the photograph. The sheet material can be molded from a single transparent material. The sheet material can be molded through a simple process. Inexpensive molding is possible. On the other hand, since the edges of the photograph are covered by the opaque film, the image can be well emphasized.

[0017] The first retainer can be a slider guided by a pair of guide rails extending parallel to both sides of the first plane, and displaced between a first position holding the photograph in accordance with the first plane and a second position detached from the first plane. The guide rails are disposed on the back side of the plate, thus maintaining the surface of the plate as a smooth surface. This ensures good visual clarity of the image. The photograph can be removed from the plate according to the displacement of the first retainer. Here, the first retainer can be formed facing outwards, on the same side as the guide rails. This allows adjustment of the shape of the back side within the plate.

[0018] The board material may also have a first plane defined on its surface and a second plane defined on its back surface. The first retainer may overlap with the surface of the board material to clamp and hold the photograph between the first retainer and the board material. The second retainer may overlap with the back surface of the board material to clamp and hold the paper between the second retainer and the board material. The photograph and the paper are physically separated by the board material. Contact between the photograph and the paper is effectively prevented. Aroma components are prevented from seeping from the paper into the photograph. Furthermore, the photograph is kept away from the channels of vaporized aroma components. Aroma components are also effectively prevented from transferring from the paper to the photograph.

[0019] The paper piece can also be positioned inside the outline of the photograph projected onto the back side in a direction perpendicular to the surface of the substrate. Because the paper piece is positioned behind the photograph, it can be obscured from the surface by the photograph even if both the first holder and the substrate are made of a single transparent material. This allows the image of the photograph to stand out well.

[0020] The sheet material can also be formed into a quadrilateral shape. The sheet material can be held in place by mutually opposing and parallel extending wall surfaces. The picture frame not only functions as a photo holder when combined with other components, but can also be assembled with other objects to enhance the enjoyment of photographs on those objects.

[0021] Invention Effects

[0022] As described above, according to the present invention, a photo frame that diffuses fragrance can be provided, and the fragrance can be easily switched. Attached Figure Description

[0047] Hereinafter, one embodiment of the present invention will be described with reference to the accompanying drawings.

[0048] Figure 1 A photo holder according to a first embodiment of the present invention is shown schematically. The photo holder 101 includes: a photo frame 103 that displays an image of a photo PC through a transparent plate 102 while emitting a fragrance; and an auxiliary member 104 that holds the photo frame 103 in an upright position on a horizontal plane PL. The photo PC can be a photo print on paper, instant film with white space around the image, etc. Here, the auxiliary member 104 has a flat plate 105 that supports the photo frame 103 and a foot plate 106 that is connected to the lower edge of the flat plate 105 and overlaps with the horizontal plane PL. The flat plate 105 and the foot plate 106 can be formed by bending a single sheet of metal (e.g., stainless steel). Therefore, the foot plate 106 is continuous from the lower end of the flat plate 105 at its front end. The flat plate 105 need only be at least magnetic. The front end of the footplate 106 is located forward of the center of gravity of the flat plate 105 and the picture frame 103, and the rear end of the footplate 106 is located backward of the center of gravity of the flat plate 105 and the picture frame 103. Therefore, the footplate 106 can support the flat plate 105 in an upright position on the horizontal plane PL. Here, the flat plate 105 is tilted backward at a specific angle around its lower end.

[0049] like Figure 2 As shown, the picture frame 103 has a plate 111 on its back side, which defines a first plane 107 for receiving the photograph PC and a second plane 109 for receiving the paper 108. The second plane 109 is configured not to overlap with the first plane 107. The second plane 109 is separate from the first plane 107. The plate 111 can be made entirely of a transparent body, for example. The transparent body can be molded from a rigid acrylic resin, for example. The plate 111 is formed of a material that blocks airflow (a non-breathable material). Here, an opaque film 112 is formed on the surface of the plate 111, at least covering the edge of the photograph PC. The opaque film 112, for example, surrounds the window 113 displaying the image of the photograph PC and extends circumferentially to the outer edge of the plate 111. Therefore, the plate 111 and the window 113 correspondingly form a transparent area (transparent plate 102) that at least covers the image of the photograph PC. The observer can view the image of the photograph PC through the transparent area. The opaque film 112 can be made of a colored coating film, for example.

[0050] The photo frame 103 has a first retainer 114 mounted on the plate 111 and holding the photograph PC in accordance with the first plane 107. The first retainer 114 is a slider guided by a pair of first guide rails 116 extending parallel to both sides of the first plane 107 and displaced between a first position holding the photograph PC in accordance with the first plane 107 and a second position disengaged from the first plane 107. Therefore, the first retainer 114 is mounted on the plate 111 in a detachable manner.

[0051] The first guide rails 116 extend horizontally and linearly. Between the first guide rails 116, a first smooth surface 117 is defined on the back side of the plate 111. The first guide rails 116 divide a guide path that engages with the first smooth surface 117. When dividing the guide path, the first guide rails 116 form a limiting edge 116a between themselves and the first smooth surface 117 to receive the first retainer 114. The limiting edge 116a allows the first retainer 114 to move horizontally along the guide path and restricts the first retainer 114 from disengaging from the first plane 107 beyond horizontal movement. Here, the first plane 107 is defined as passing through the inner surface of a recess 118 in the first smooth surface 117. The recess 118 is closed by the first retainer 114, which overlaps with the first smooth surface 117 at a first position, dividing a photo chamber for storing the photo PC between the first retainer 114 and the first plane 107. The outline of the recess 118 only needs to conform to the outline of the photo PC.

[0052] The first retainer (slider) 114 is formed as a flat plate that completely closes the guide path at a first position. The upper edge of the flat plate engages with the limiting edge 116a of the upper first guide rail 116. The lower edge of the flat plate engages with the limiting edge 116a of the lower first guide rail 116. The first retainer (slider) 114 can be molded, for example, from rigid acrylic resin. The first retainer 114 is formed from a material that blocks airflow (a non-ventilated material).

[0053] The picture frame 103 has a second retainer 115 mounted on the plate 111 and holding the paper 108 in accordance with the second plane 109. The second retainer 115 is a slider guided by a pair of second guide rails 121 extending parallel to both sides of the second plane 109 and displaced between a first position holding the paper 108 in accordance with the second plane 109 and a second position disengaged from the second plane 109. Therefore, the second retainer 115 is mounted on the plate 111 in a detachable manner.

[0054] The second guide rail 121 extends horizontally and linearly. A second smooth surface 122 is defined on the back side of the sheet 111 between the second guide rails 121. The second guide rails 121 divide a guide path that engages with the second smooth surface 122. When dividing the guide path, the second guide rail 121 forms a limiting edge 121a between itself and the second smooth surface 122 to receive the second retainer 115. The limiting edge 121a allows the second retainer 115 to move horizontally along the guide path and restricts the second retainer 115 from disengaging from the second plane 109 beyond horizontal movement. Here, the second plane 109 is defined as passing through the inner surface of a recess 123 in the second smooth surface 122. The recess 123 is closed by the second retainer 115, which overlaps with the second smooth surface 122 at a first position, dividing a paper chamber for receiving the paper sheet 108 between the second retainer 115 and the second plane 109.

[0055] The second retainer (slider) 115 is formed as a flat plate that completely closes the guide path at the first position. The upper edge of the flat plate engages with the limiting edge 121a of the upper second guide rail 121. The lower edge of the flat plate engages with the limiting edge 121a of the lower second guide rail 121. The second retainer (slider) 115 can be molded, for example, from rigid acrylic resin. The second retainer 115 is formed from a material that blocks airflow (a non-ventilated material).

[0056] Paper sheet 108 contains aromatic components. Paper sheet 108 is formed as a strip in the horizontal direction. The outline of the recess 123 can be set according to the outline of paper sheet 108. Paper sheet 108 has the ability to absorb solvents that retain aromatic components. For example, perfume can penetrate paper sheet 108. Paper sheet 108 can also be made of paper material that changes color according to the absorption of aromatic components. For example, litmus paper can change color according to the pH that changes accordingly with the absorption of aromatic components.

[0057] like Figure 3 As shown, a magnet 124 is fixed on the back side of the plate 111 at a position deviating from the guide path defined by the first guide rail 116 and the second guide rail 121. When the picture frame 103 is supported by the plate 105 of the auxiliary component 104, the magnet 124 contacts the surface of the plate 105. The picture frame 103 is held on the plate 105 by magnetic force. The magnet 124 protrudes from a plane containing the back side of the plate 111 at a defined height. The magnet 124 forms a gap Hs between the second holder 115 and the plate 105 of the auxiliary component 104. The gap Hs is open to the atmosphere at the outer periphery of the plate 111.

[0058] like Figure 4 As shown, the second retainer 115 has a through-hole 125 connecting the paper chamber to the external space. The aroma components of the paper 108 can diffuse into the external space through the through-hole 125. The gap Hs between the second retainer 115 and the plate 105 connects the through-hole 125 to the atmosphere. Alternatively, the through-hole can also connect the paper chamber to the external space through the plate 111.

[0059] In addition, such as Figure 5 As shown, the first plane 107 and the second plane 109 can also be formed as the same surface as the back of the board 111. Here, the first plane 107 is contained within the first smooth surface 117. At the position where it overlaps with the first plane 107, a recess 118 is provided on the first holder 114. At a first position of the first holder 114, the first smooth surface 117 (first plane 107) closes the recess 118. In this way, a photo chamber for storing the photo PC is defined between the first holder 114 and the first plane 107. Similarly, the second plane 109 is contained within the second smooth surface 122. At the position where it overlaps with the second plane 109, a recess 123 is provided on the second holder 115. At a first position of the second holder 115, the second smooth surface 122 (second plane 109) closes the recess 123. In this way, a paper chamber for storing the paper 108 is defined between the second holder 115 and the second plane 109. Similarly, the second retainer 115 has a through-hole 125 connecting the paper chamber to the outside space. The aroma components of the paper 108 can diffuse into the outside space through the through-hole 125. The spacing Hs between the second retainer 115 and the plate 105 connects the through-hole 125 to the atmosphere.

[0060] like Figure 6As shown, the auxiliary component 104 may also have a positioning piece 126 disposed between the flat plate 105 and the foot plate 106, supporting the lower edge of the frame 103. When the lower edge of the frame 103 abuts against the positioning piece 126, the lower edge of the frame 103 can be positioned horizontally. The position of the frame 103 can be set before magnetic fixing. The positioning piece 126 only needs to protrude forward from the surface of the flat plate 105. When the flat plate 105 and the foot plate 106 are formed from a single sheet of metal, the positioning piece 126 can be established between the flat plate 105 and the foot plate 106 by bending. The front end of the foot plate 106 is located forward of the center of gravity of the flat plate 105 and the frame 103, and the rear end of the foot plate 106 is located rearward of the center of gravity of the flat plate 105 and the frame 103, so the foot plate 106 can support the flat plate 105 in an upright position on the horizontal plane PL.

[0061] Next, the function of the photo holder 101 in the first embodiment will be explained. The photo holder 101 is disposed on the horizontal surface PL of furniture such as a table or shelf. The foot plate 106 of the auxiliary member 104 overlaps with the horizontal surface PL. The flat plate 105 is disposed on the horizontal surface PL in an upright position. A photo frame 103 is fixed to the flat plate 105. A magnet 124 binds the photo frame 103 to the flat plate 105. The image of the photo PC is displayed forward through the transparent plate 102. The observer can enjoy the image. The photo frame 103 is magnetically attached to the auxiliary member 104, so the photo frame 103 can be easily removed from the auxiliary member 104.

[0062] The aroma diffuses from the paper 108. The aroma flows out of the paper chamber through the through-hole 125. The aroma diffuses from the outer periphery of the frame 103 into the atmosphere via the gap Hs between the second holder 115 and the plate 105. In this way, the observer can enjoy the fragrance while viewing the image. Visual sensitivity can be enhanced by olfactory sensitivity. When past visual information is associated with the fragrance in the observer's memory, the observer can immerse themselves in a revived sense of presence.

[0063] When replacing the photo chamber, the photo frame 103 is removed from the auxiliary component 104. Within the photo frame 103, the first retainer 114 is removed from the plate 111. The first retainer 114 is driven along a guide path from a first position to a second position. The photo chamber is open. The photo chamber is removed from the recess 118. Thus, the photo chamber can be separated from the plate 111 as a single unit.

[0064] A new photographic plate (PC) is positioned in the recess 118. The PC overlaps with the first plane 107. The image on the PC is aligned with the transparent plate 102. A first retainer 114 is mounted on the plate 111. The first retainer 114 is driven from the second position to the first position along a guide path. The first retainer 114 closes the photographic chamber. This allows the PC to be replaced.

[0065] The user of the photo holder 101 can replenish the fragrance component to the paper 108. When replenishing the fragrance component, the photo frame 103 is removed from the auxiliary component 104. Within the photo frame 103, the second retainer 115 is removed from the substrate 111. The second retainer 115 is driven along a guide path from a first position to a second position. The paper chamber is open. The paper 108 is removed from the recess 123. Thus, the paper 108 can be separated from the substrate 111 individually. When replenishing the fragrance component, the user can immerse the paper 108 in a liquid containing the fragrance component, or blow a liquid containing the fragrance component (e.g., perfume) onto the paper 108.

[0066] Paper sheet 108 is disposed in recess 123. Paper sheet 108 overlaps with second plane 109. Second retainer 115 is mounted on board 111. Second retainer 115 is driven from second position to first position along guide path. Second retainer 115 closes paper sheet chamber. In this way, aroma components can be replenished to paper sheet 108. Even if the fragrance disappears, the user can enjoy the fragrance again with replenishment. Even if the fragrance weakens, the fragrance can be enhanced with replenishment.

[0067] When the second retainer 115 is removed from the board 111, the paper 108 can be separated from the board 111 as a single unit. The paper 108 is itself an absorber of the fragrance components, so the fragrance components only need to permeate into the paper 108. For example, the fragrance components can be blown onto the paper as in perfume. The fragrance components can be replenished effortlessly in a short time. Furthermore, the fragrance can be easily switched to other scents by replacing the individual paper 108 units. Different fragrance components can be blown onto new paper 108, just like in perfume.

[0068] Furthermore, since the photograph PC and the paper 108 are held on the first plane 107 and the second plane 109 respectively, the paper 108 is disposed separately from the photograph PC. This effectively prevents contact between the photograph PC and the paper 108. It also prevents fragrance components from seeping from the paper 108 into the photograph PC.

[0069] The plate 111 of this embodiment is a resin plate with a first plane 107 and a second plane 109 defined on its back side, and has a transparent area covering the image of the photographic PC. An observer can view the image of the photographic PC through the transparent area. The plate 111 protects the image of the photographic PC while ensuring visual verifiability. Here, when the second holder 115 is removed, the first holder 114 can remain on the plate 111. When the paper 108 is replaced, the photographic PC can continue to be held on the plate 111 as is. Positional displacement of the photographic PC can be avoided when the paper 108 is replaced.

[0070] In this embodiment, the second retainer 115 is a slider guided by a pair of second guide rails 121 extending linearly parallel to both sides of the second plane 109, and displaced between a first position holding the paper 108 in accordance with the second plane 109 and a second position disengaged from the second plane 109. The second guide rails 121 are disposed on the back side of the plate 111, so the surface of the plate 111 can be maintained as a smooth surface. This ensures good visual clarity of the image. The paper 108 can be removed from the plate 111 according to the displacement of the second retainer 115. Here, the second retainer 115 can be formed with an outward facing surface that is the same as the second guide rails 121. This allows for adjustment of the shape of the back side within the plate 111.

[0071] As described above, the substrate 111 is made of a transparent material. An opaque film 112 is formed on the surface of the substrate 111 to cover the edges of the photographic PC. The substrate 111 can be molded from a single transparent material. The substrate 111 can be molded through a simple process. Inexpensive molding is possible. On the other hand, since the edges of the photographic PC are covered by the opaque film 112, the image can be well emphasized.

[0072] The first retainer 114 is a slider guided by a pair of first guide rails 116 extending parallel to both sides of the first plane 107, and displaced between a first position holding the photograph PC in imitation of the first plane 107 and a second position disengaged from the first plane 107. The first guide rails 116 are disposed on the back side of the plate 111, so the surface of the plate 111 can be maintained as a smooth surface. This ensures good visual clarity of the image. The photograph PC can be removed from the plate 111 according to the displacement of the first retainer 114. Here, the first retainer 114 can be formed with an outward facing surface that is the same as the first guide rails 116. This allows for adjustment of the shape of the back side within the plate 111.

[0073] like Figure 7 As shown, instead of the aforementioned auxiliary component 104, the auxiliary component 131 can also be a shaft 132 mounted on the plate 111 and extending rearward from the back of the plate 111. The shaft 132 may have, for example, a lead screw 133 having an axis perpendicular to the back of the plate 111. The shaft 132 can be formed, for example, as a cylinder coaxial with the lead screw 133. The lead screw 133 is screwed into the back of the plate 111. Thus, the shaft 132 can be easily fixed to the plate 111 by means of screws. The shaft 132 may be formed from, for example, a metal material such as aluminum.

[0074] According to the shaft 132, the frame 103 is supported by the horizontal plane PL at the lower rear end of the plate 111, and the shaft 132 is also supported by the horizontal plane PL at its rear end. The lower rear end of the plate 111 is located forward of the center of gravity of the frame 103, and the rear end of the shaft 132 is located backward of the center of gravity of the frame 103. Therefore, the shaft 132 can support the frame 103 in an upright position on the horizontal plane PL. Here, the frame 103 is tilted backward at a specific angle around its lower rear end.

[0075] like Figure 8 As shown, instead of the aforementioned auxiliary components 104 and 131, auxiliary component 134 can also be a weight 135 disposed on the horizontal plane PL. The weight 135 can be, for example, formed into a cuboid from a block of metal with a specific gravity of 7 or higher, such as stainless steel. A horizontally extending linear groove 136 is formed on the upper surface of the weight 135. For example, the lower end of the picture frame 103 can be inserted into the groove 136 from above. In this case, the center of gravity of the weight 135 and the picture frame 103 is positioned within the contact area between the weight 135 and the horizontal plane PL. As a result, the weight 135 can hold the picture frame 103 in an upright position on the horizontal plane PL.

[0076] Figure 9 The second embodiment of the photo holder is shown schematically. The photo holder 141 includes: a photo frame 143 that diffuses fragrance while displaying an image of the photo PC through a transparent plate 142; and an auxiliary member 144 that holds the photo frame 143 in an upright position on a horizontal plane PL. The photo PC can be a printed photo on paper, instant film with white space around the image, etc. The transparent plate 142 can be made of glass, for example. The photo PC is superimposed on the back of the transparent plate 142. A frame 146 is superimposed on the surface of the transparent plate 142, defining a window 145 for displaying the image of the photo PC. The frame 146 can be made of an opaque hard resin material or wood. The frame 146 covers the edge of the transparent plate 142 all around its perimeter. An observer can view the image of the photo PC through the transparent plate 142.

[0077] like Figure 10As shown, the frame 143 has a plate 153, which has a first plane 151 on its surface for receiving the photograph PC and a second plane 152 on its back surface for receiving a strip of paper 108 containing fragrance components. The second plane 152 is separate from the first plane 151. The plate 153 can be made entirely of an opaque material, for example. The plate 153 can be made of an opaque hard resin material or molded from wood, for example. The plate 153 is formed of a non-breathable material that blocks airflow. When the plate 153 is inserted into the frame 146 from the back, the first plane 151 presses the photograph PC against the back of the transparent plate 142. In this way, the photograph PC is held in accordance with the first plane 151. The frame 146 and the transparent plate 142 cooperate to form the first retainer of the present invention.

[0078] Fasteners 154 are mounted on the frame 146 to hold the plate 153 embedded therein. The fasteners 154 are displaced between a first position where they engage with the back of the embedded plate 153 from the rear and a second position where they rotate about a rotation axis 155 and disengage from the plate 153. When all the fasteners 154 are disengaged from the plate 153 in the second position, the plate 153 can be removed from the frame 146. The photo PC can be replaced after the plate 153 is removed.

[0079] The picture frame 143 also has a second retainer 156, which is detachably mounted on the board 153 to hold the paper 108 in accordance with the second plane 152. The second retainer 156 is a slider guided by a pair of slide rails 157 extending parallel to both sides of the second plane 152 and displaced between a first position holding the paper 108 in accordance with the second plane 152 and a second position disengaged from the second plane 152. The slide rails 157 extend horizontally and linearly. A smooth surface 158 is defined on the back of the board 153 between the slide rails 157 and each other. The slide rails 157 divide a guide path that engages with the smooth surface 158. When the guide path is divided, the slide rails 157 form a limiting edge 157a between themselves and the smooth surface 158 to receive the second retainer 156. The limiting edge 157a allows the second retainer 156 to move horizontally along the guide path and restricts the second retainer 156 from disengaging from the second plane 152 beyond horizontal movement. At this time, guide paths 159 are defined on the frame 146, which are continuous from the guide paths and open at the periphery of the frame 146. The second retainer 156 passes through the guide paths 159 when it is displaced in the horizontal direction.

[0080] Here, the second plane 152 is defined as passing through the inner surface of the recess 161 of the smooth surface 158. The recess 161 is closed by a second retainer 156 that overlaps with the smooth surface 158 at the first position, dividing a paper chamber for receiving the paper sheet 108 between the second retainer 156 and the second plane 152. The second retainer (slider) 156 is formed as a flat plate that closes the entire guide path at the first position. The upper edge of the flat plate engages with the limiting edge 157a of the upper slide rail 157. The lower edge of the flat plate engages with the limiting edge 157a of the lower slide rail 157.

[0081] The second retainer (slider) 156 can be molded from, for example, rigid acrylic resin. The second retainer 156 is formed of a non-breathable material that blocks airflow. The second retainer 156 has a through hole 162 connecting the paper chamber to the external space. The aroma components of the paper 108 can diffuse into the external space through the through hole 162.

[0082] The auxiliary component 144 has a support leg 164 mounted on the plate 153, displaced between a first position overlapping the plate 153 and a second position rotating about the axis of rotation 163 away from the plate 153 by a defined angle. The support leg 164 can be formed, for example, from a polygonal plate overlapping the plate 153. The support leg 164 defines a first edge 164a extending linearly parallel to the lower end of the frame 146 at a position away from the axis of rotation 163, and a second edge 164b extending linearly parallel to the side ends of the frame 146 at a position away from the axis of rotation 163.

[0083] Similar to a typical photo holder, when the lower end of the frame 146 is supported by the horizontal plane PL and the second-position support leg 164 is supported by the horizontal plane PL at its first edge 164a, the support leg 164 can hold the photo frame 143 in a vertical, upright position on the horizontal plane PL. At this time, the frame 146 tilts backward at a specific angle around its lower end. The lower end of the frame 146 is located forward of the center of gravity of the photo frame 143, and the first edge 164a of the support leg 164 is located backward of the center of gravity of the photo frame 143. When the side end of the frame 146 is supported by the horizontal plane PL and the second-position support leg 164 is supported by the horizontal plane PL at its second edge 164b, the support leg 164 can hold the photo frame 143 in a horizontal, upright position on the horizontal plane PL. At this time, the frame 146 tilts backward at a specific angle around its side end. The side end of the frame 146 is located in front of the center of gravity of the frame 143, and the second edge 164b of the support leg 164 is located behind the center of gravity of the frame 143.

[0084] Similar to a typical photo holder, the photo frame 143 may also have a first keyhole component 166 and a second keyhole component 167 for wall mounting. The first keyhole component 166 and the second keyhole component 167 are mounted on the frame 146. Alternatively, the first keyhole component 166 and the second keyhole component 167 may also be mounted on the back of the plate 153. The first keyhole component 166 has an elongated hole 166a extending in a direction perpendicular to the longitudinal direction of the frame 146 and an enlarging entry hole 166b that continues in the direction of gravity from the lower end of the elongated hole 166a. Similarly, the second keyhole component 167 has an elongated hole 167a extending in a direction perpendicular to the transverse direction of the frame 146 and an enlarging entry hole 167b that continues in the direction of gravity from the lower end of the elongated hole 167a. The wall fittings (not shown) may have the following components: a shaft that extends vertically from the wall in a horizontal direction and is guided along the elongated holes 166a and 167a; and an enlarged head that engages with the front end of the shaft to allow entry and exit relative to the inlet holes 166b and 167b and to prevent it from falling out of the elongated holes 166a and 167a.

[0085] Next, the function of the photo holder 141 in the second embodiment will be explained. The photo holder 141 is provided on the horizontal plane PL of furniture such as a table or shelf. For example, in a vertical photo PC, the lower end of the frame 146 and the first edge 164a of the support leg 164 are supported by the horizontal plane PL. In this arrangement, the support leg 164 is restricted to a second position about the rotation axis 163. The frame 146 is arranged in an upright position on the horizontal plane PL. The image of the photo PC is displayed forward through the transparent plate 142. The observer can enjoy appreciating the image. In the case of a horizontal photo PC, the side end of the frame 146 and the second edge 164b of the support leg 164 are supported by the horizontal plane PL.

[0086] The aroma diffuses from the paper piece 108. The aroma flows out of the paper chamber through the through-hole 162 into the outer space. The aroma diffuses into the atmosphere. In this way, the observer can enjoy the aroma while appreciating the image. Visual sensitivity can be enhanced through olfactory sensitivity. When past visual information in the observer's memory is associated with the aroma, the observer can immerse themselves in a revived sense of presence.

[0087] When replacing the photo PC, the plate 153 is removed from the frame 146. During removal, the fastener 154 is driven from a first position to a second position about the rotation axis 155. Upon removal, the plate 153 separates from the photo PC. The second retainer 156 remains on the plate 153. The photo PC is peeled off from the back of the transparent plate 142. The transparent plate 142 can remain on the frame 146.

[0088] A new photo PC is mounted on the frame 146 from the rear. The photo PC overlaps the transparent plate 142. The image on the photo PC is aligned with the window 145 of the frame 146. The plate 153 is mounted on the frame 146. During installation, the fastener 154 is driven from a second position to a first position about the rotation axis 155. This allows the photo PC to be replaced.

[0089] The user of the photo holder 141 can replenish the fragrance component to the paper 108. While replenishing the fragrance component, the connection between the board 153 and the frame 146 is maintained. The second retainer 156 is removed from the board 153. The second retainer 156 is driven along a guide path from a first position to a second position. The paper chamber is open. The paper 108 is removed from the recess 161. In this way, the paper 108 can be separated from the board 153 individually. When replenishing the fragrance component, the user can immerse the paper 108 in a liquid containing the fragrance component, or blow a liquid containing the fragrance component (such as perfume) onto the paper 108.

[0090] Paper sheet 108 is disposed in recess 161. Paper sheet 108 overlaps second plane 152. Second retainer 156 is mounted on plate 153. Second retainer 156 is driven from second position to first position along guide path. Second retainer 156 closes paper sheet chamber. In this way, aroma components can be replenished to paper sheet 108. Even if the fragrance disappears, the user can enjoy the fragrance again with replenishment. Even if the fragrance weakens, the fragrance can be enhanced with replenishment.

[0091] When the second retainer 156 is removed from the board 153, the paper 108 can be separated from the board 153 as a single unit. The paper 108 is itself an absorber of the fragrance components, so the fragrance components only need to permeate into the paper 108. For example, the fragrance components can be blown onto the paper as in perfume. The fragrance components can be replenished effortlessly in a short time. Furthermore, the fragrance can be easily switched to other scents by replacing the individual paper 108 units. Different fragrance components can be blown onto new paper 108, just like in perfume.

[0092] In this embodiment, the plate 153 has a first plane 151 on its surface and a second plane 152 on its back surface. A transparent plate 142 of the first holder overlaps the surface of the plate 153, clamping and holding the photograph PC between the transparent plate 142 and the plate 153. A second holder 156 overlaps the back surface of the plate 153, clamping and holding the paper 108 between the second holder 156 and the plate 153. The photograph PC and the paper 108 are physically separated by the plate 153. Contact between the photograph PC and the paper 108 is effectively prevented. Fragrance components are prevented from seeping from the paper 108 into the photograph PC. Furthermore, the photograph PC is kept away from the channels of vaporized fragrance components. Fragrance components are also effectively prevented from transferring from the paper 108 to the photograph PC.

[0093] Alternatively, the support leg 164 and keyhole components 166, 167 can also be mounted on a magnetic plate. For example, the frame 103 can be fixed to the plate by the magnetic force of the magnet 124. For example, in a vertical photo PC, the lower end of the plate and the first edge 164a of the support leg 164 only need to be supported by the horizontal plane PL. In this arrangement, the support leg 164 is restricted to a second position about the rotation axis 163. The frame 146 is positioned upright on the horizontal plane PL. The image of the photo PC is displayed forward through the transparent plate 102. The observer can enjoy the image. In the case of a horizontal photo PC, the side end of the plate and the second edge 164b of the support leg 164 only need to be supported by the horizontal plane PL.

[0094] Figure 11 A photo frame used in the photo holder of the third embodiment is shown schematically. The photo frame 173 of this embodiment can be combined with the aforementioned auxiliary component 104 to form a photo holder 101. The photo frame 173 has a plate 176, which has a first plane 174 on its surface for receiving a photograph PC and a second plane 175 on its back surface for receiving a piece of paper 108. The second plane 175 is separate from the first plane 174. The plate 176 can, for example, be made entirely of a transparent material. The transparent material can, for example, be molded from rigid acrylic resin. Alternatively, the plate 176 can also be formed of an opaque material. The plate 176 is formed of a material that blocks ventilation (a non-ventilated material).

[0095] The frame 173 also includes: a first retainer 177, which is detachably mounted on the plate 176 to hold the photograph PC in accordance with a first plane 174; and a second retainer 178, which is detachably mounted on the plate 176 to hold the paper 108 in accordance with a second plane 175. The first retainer 177 overlaps the surface of the plate 176, clamping and holding the photograph PC between the first retainer 177 and the plate 176. The first retainer 177 can, for example, be made entirely of a transparent body. The transparent body can, for example, be molded from rigid acrylic resin. An observer can view the image of the photograph PC through the first retainer 177. Here, the outline of the first retainer 177 overlaps with the outline of the plate 176. Therefore, the first retainer 177 and the plate 176 can be identified as a cuboid.

[0096] When installing the first retainer 177, a first magnetic body 181 is fixed to the surface of the plate 176 at a position offset from the first plane 174 (photograph PC). A first magnet 182, which exerts a magnetic force on the first magnetic body 181, is fixed to the back of the first retainer 177. The first magnet 182 is embedded in the back of the first retainer 177. When the first retainer 177 is supported by the surface of the plate 176, the first magnetic body 181 and the first magnet 182 are in surface contact. The first magnetic body 181 only needs to have a contour that overlaps with the first magnet 182 when the first retainer 177 overlaps with the plate 176. The first retainer 177 is fixed to the plate 176 by magnetic force. The photograph PC is sandwiched between the overlapping plate 176 and the first retainer 177. The first magnetic body 181 and the first magnet 182 can be formed of a transparent material. The first magnetic body 181 can also be embedded in the surface of the plate 176.

[0097] The second retainer 178 overlaps the back side of the substrate 176, clamping and holding the paper piece 108 between the second retainer 178 and the substrate 176. The paper piece 108 is positioned inside the outline of a photographic PC projected onto the back side of the substrate 176 in a direction perpendicular to the surface of the substrate 176. The second retainer 178 can be made entirely of a transparent material, for example, molded from a rigid acrylic resin. The second retainer 178 is formed of a non-breathable material that blocks airflow. Here, the outline of the second retainer 178 overlaps with the outlines of the first retainer 177 and the substrate 176. Therefore, the first retainer 177, the substrate 176, and the second retainer 178 can be identified as a cuboid. Alternatively, the second retainer 178 can also be formed of an opaque material.

[0098] When installing the second retainer 178, a second magnet 183 is fixed to the back of the plate 176. The second magnet 183 is positioned inside the outline of the first magnetic body 181 projected in a direction perpendicular to the surface of the plate 176. A second magnetic body 184 is fixed to the surface of the second retainer 178, which is coupled to the corresponding second magnet 183 by the magnetic force exerted by the second magnet 183. The second magnet 183 is embedded in the back of the plate 176. When the second retainer 178 is supported by the back of the plate 176, the second magnetic body 184 is in surface contact with the second magnet 183. The second magnetic body 184 only needs to have an outline that overlaps with the second magnet 183 when the second retainer 178 overlaps with the plate 176. The second retainer 178 is fixed to the plate 176 by magnetic force. A piece of paper 108 is sandwiched between the overlapping plate 176 and the second retainer 178. The second magnetic body 184 and the second magnet 183 can be formed of a transparent material. Depending on the thickness of the paper sheet 108 and the thickness of the second magnet 184, a gap is formed between the back surface of the plate 176 and the surface of the second retainer 178. As long as the gap is ensured, the second magnet 184 can also be embedded in the surface of the second retainer 178.

[0099] A third magnet 185 is fixed to the back of the second retainer 178. The third magnet 185 is positioned inside the outline of the second magnetic body 184 projected in a direction perpendicular to the surface of the second retainer 178. The third magnet 185 is embedded in the back of the second retainer 178. When the picture frame 173 is supported by the plate 105 of the auxiliary component 104, the third magnet 185 comes into surface contact with the surface of the plate 105. The picture frame 173 is held on the plate 105 by magnetic force. Here, the second retainer 178 can be constructed in the same way as the plate 176. If the plate 176 and the second retainer 178 are shared, manufacturing costs can be reduced.

[0100] Next, the function of the photo frame 173 in the third embodiment will be explained. The photo frame 173 can replace the aforementioned photo frame 103 and be connected to the auxiliary component 104 of the photo holder 101. The photo holder 101 is provided on the horizontal surface PL of furniture such as a table or shelf. The foot plate 106 of the auxiliary component 104 overlaps with the horizontal surface PL. The flat plate 105 is arranged in an upright position on the horizontal surface PL. The photo frame 173 is fixed on the flat plate 105. The magnet 185 binds the photo frame 173 to the flat plate 105. The image of the photo PC is displayed forward through the first holder 177. The observer can enjoy the image. The photo frame 173 is bound to the auxiliary component 104 by magnetic force, so the photo frame 173 can be easily removed from the auxiliary component 104.

[0101] The aroma diffuses from the paper 108. It also diffuses into the atmosphere from the outer periphery of the frame 173 via the space between the board 176 and the second holder 178. The observer can enjoy the aroma while viewing the image. Visual sensitivity can be enhanced by olfactory sensitivity. When past visual information is associated with the aroma in the observer's memory, the observer can immerse themselves in a revived sense of presence.

[0102] When replacing the photo PC, the photo frame 173 is removed from the auxiliary component 104. Within the photo frame 173, the first retainer 177 is removed from the plate 176. The first retainer 177 is held to the plate 176 by the magnetic force of the first magnet 182, thus allowing for easy removal from the plate 176. The photo PC is then removed from the first plane 174. The photo PC can be detached from the plate 176 as a single unit.

[0103] The new photo PC overlaps with the first plane 174 of the plate 176. The image of the photo PC is aligned. A first retainer 177 is mounted on the plate 176. The first retainer 177 overlaps the surface of the plate 176. The first retainer 177 covers the photo PC. The first retainer 177 is fixed to the plate 176 by the magnetic force of the first magnet 182. In this way, the photo PC can be replaced.

[0104] The user of the photo holder 101 can replenish the fragrance component to the paper 108. When replenishing the fragrance component, the photo frame 173 is removed from the auxiliary component 104. Within the photo frame 173, the second holder 178 is removed from the substrate 176. The second holder 178 is attached to the substrate 176 by the magnetic force of the second magnet 183, thus allowing for easy removal from the substrate 176. The paper 108 is then removed from the second plane 175. The paper 108 can be separated from the substrate 176 individually. When replenishing the fragrance component, the user can immerse the paper 108 in a liquid containing the fragrance component, or blow a liquid containing the fragrance component (such as perfume) onto the paper 108.

[0105] Paper piece 108 overlaps with the second plane 175 of board 176. Paper piece 108 is aligned. Second retainer 178 is mounted on board 176. Second retainer 178 overlaps with the back of board 176. Second retainer 178 covers paper piece 108. Second retainer 178 is fixed to board 176 by the magnetic force of second magnet 183. In this way, fragrance components can be replenished to paper piece 108. Even if the fragrance disappears, the user can enjoy the fragrance again by replenishing it. Even if the fragrance weakens, the fragrance can be enhanced by replenishing it.

[0106] When the second retainer 178 is removed from the board 176, the paper 108 can be separated from the board 176 as a single unit. The paper 108 is itself an absorber of the fragrance components, so the fragrance components only need to permeate into the paper 108. For example, the fragrance components can be blown onto the paper as in perfume. The fragrance components can be replenished effortlessly in a short time. Furthermore, the fragrance can be easily switched to other scents by replacing the individual paper 108 units. Different fragrance components can be blown onto new paper 108, just like in perfume.

[0107] In this embodiment, the substrate 176 has a first plane 174 defined on its surface and a second plane 175 defined on its back surface. A first retainer 177 overlaps the surface of the substrate 176, clamping and holding the photograph PC between the first retainer 177 and the substrate 176. A second retainer 178 overlaps the back surface of the substrate 176, clamping and holding the paper 108 between the second retainer 178 and the substrate 176. The photograph PC and the paper 108 are physically separated by the substrate 176. Contact between the photograph PC and the paper 108 can be effectively avoided. It can prevent aroma components from seeping from the paper 108 into the photograph PC. Furthermore, the photograph PC can be kept away from the channels of vaporized aroma components. It can also effectively prevent aroma components from transferring from the paper 108 to the photograph PC.

[0108] In this embodiment, the paper sheet 108 is disposed inside the outline of the photographic PC projected onto the back side of the plate 176 in a direction perpendicular to the surface of the plate 176. Because the paper sheet 108 is disposed behind the photographic PC, even though both the first holder 177 and the plate 176 are formed from a single transparent material, the paper sheet 108 can be obscured from the surface by the photographic PC. The image on the photographic PC can then be well highlighted.

[0109] Figure 12 A product packaging unit according to one embodiment of the present invention is shown schematically. The product packaging unit 191 has an outer box 192. The outer box 192 is formed by a lower outer box 193 and an upper outer box 194 that covers the lower outer box 193 from above. Figure 13 As shown, the lower outer box 193 consists of a quadrilateral base plate 193a and four side plates 193b that stand vertically from the four sides of the base plate 193a. A cuboid storage space is divided inside the lower outer box 193. An inner box (product packaging box) 11 is stored in this storage space. The base plate 193a and side plates 193b are each formed from flat cardboard. The base plate 193a and side plates 193b are joined together by edges. The lower outer box 193 has a seamless, continuous appearance through the edges.

[0110] The upper outer box 194 consists of a quadrilateral top plate 194a and four side plates 194b descending vertically from the four sides of the top plate 194a. The top plate 194a supports the upper end of the side plates 193b of the lower outer box 193, closing the opening 195 of the lower outer box 193 surrounded by the side plates 193b. The side plates 194b of the upper outer box 194 surround the side plates 193b of the lower outer box 193. The top plate 194a and the side plates 194b are each formed of flat cardboard. The top plate 194a and the side plates 194b are joined together by ridges. For example, the logo of the seller or manufacturer can be printed on the upper surface of the upper outer box 194. The upper outer box 194 has a seamless, continuous appearance through the ridges. The upper outer box 194 is generally opaque. Alternatively, the top plate 194a can also be made of a transparent resin material.

[0111] like Figure 14 As shown, the inner box 11 has a lower box body 12 and an upper box body 13 that overlaps with and forms a cuboid together with the lower box body 12. The lower box body 12 has: a rigid resin molded body having a base plate 14a with a quadrilateral outline and four side walls 14b that rise vertically from the four sides of the base plate 14a; and a sticker 15 that is pasted on the outer surface of the resin molded body to decorate it. The upper box body 13 has: a rigid resin molded body having a top plate 16a and side walls 16b, the top plate 16a supporting the picture frame 103 by means of a quadrilateral recess 61, the side walls 16b descending from the four sides of the top plate 16a and mating at their lower ends with the upper ends of the side walls 14b of the lower box body 12 to form the side walls of the inner box 11; and a sticker 17 that is pasted on the outer surface of the resin molded body to decorate it. Stickers 15 and 17 can be made of resin sheets with a suede or fabric pattern, for example. Sticker 17 covers the inner surface of the recess 61. The inner surface of the recess 61 is neatly arranged by sticker 17. The upper box 13 is formed of a non-breathable material, at least within the area separating the recess 61.

[0112] The picture frame 103 is fixed within the recess 61, conforming to its outline. A sheet 111 is embedded in the recess 61. During embedding, the sheet 111 contacts the inner wall surface of the recess 61, for example, at its upper and lower edges when viewed from above. The upper and lower edges (or either one) position the sheet 111 vertically when viewed from above. A flat surface 63 is defined on the surface of the sheet 111. The space on the flat surface 63 is surrounded by an enclosure 64. The enclosure 64 has a wall surface 64a that rises from the horizontal plane containing the flat surface 63, conforming to the outline of the recess 61. The wall surface 64a is continuous from the inner wall surface of the recess 61 in a vertical plane along each edge of the outline. The wall surface 64a guides the descent of the sheet 111 in the vertical direction. Thus, the sheet 111 and the enclosure 64 cooperate on the upper surface of the upper housing 13 to form a tray. The sheet 111 constitutes the entire bottom plate of the tray. Here, the recess 61 defines a space 65 adjacent to the outer periphery of the plate 111 and opening on a horizontal plane including the flat surface 63. The space 65 is located on the outer side of the left and right edges when viewed from above. The space 65 may also be located on either the left or right edge. The space 65 is sized to prevent small items from falling when used as a tray.

[0113] like Figure 15 As shown, a cushioning material 18 is embedded in the cuboid space of the lower housing 12, which is surrounded by side walls 14b. The cushioning material 18 is formed, for example, of a sponge and a fabric 18a covering the sponge. A slit 19 is formed in the cushioning material 18. A ring (jewelry) 21 is inserted, for example, into the slit 19. Under the elastic force of the cushioning material 18, the ring 21 is held within the slit 19.

[0114] The ring 21, for example, includes: a platinum ring component 22 having a diameter corresponding to the thickness of a finger; and a diamond bead 23 fixed to a pedestal of the ring component 22. There may be one or more diamond beads 23. The diamond beads 23 possess strong or higher blue fluorescence (strong blue or very strong blue). The diamond beads 23 emit a transparent glow under visible light (e.g., natural light or electric light), and on the other hand, emit a blue glow under ultraviolet light. The diamond beads 23 are thus supported by the lower housing 12. When multiple diamond beads 23 are configured, the blue fluorescence of all (or each group uniformly designed) diamond beads 23 should be uniformly strong blue or very strong blue.

[0115] An inner lining material 24 is embedded within the cuboid space of the upper housing 13, which is surrounded by side walls 16b. The inner lining material 24 has a decorative top plate 24a forming a quadrilateral outline of the top surface of the inner housing 11, and four inner lining panels 24b that are continuous from the four sides of the decorative top plate 24a and overlap the four side walls 16b from the inside. Here, the four inner lining panels 24b are not adhered to the inner surface of the side walls 16b, and the inner lining material 24 is stored in the upper housing 13 in a removable manner.

[0116] like Figure 16 As shown, the upper housing 13 is connected to the lower housing 12 in a freely opening and closing manner via a hinge 26. The hinge 26 has: a first blade 27, which is fixed from the inside by overlapping a side wall 16b of the upper housing 13, the first blade 27 having multiple tubes 27a; a second blade 28, which is fixed from the inside by overlapping a side wall 14b of the lower housing 12, the second blade 28 having multiple tubes 28a arranged in series with the tubes 27a of the first blade 27; and a hinge pin 29, which is inserted into both the tubes 27a of the first blade 27 and the tubes 28a of the second blade 28. The first blade 27 and the second blade 28 rotate relative to each other about the hinge pin 29. The central axis of the hinge pin 29 corresponds to the axis of rotation of the upper housing 13 during opening and closing.

[0117] A leaf spring 31 is connected to hinge 26. For example... Figure 17 As shown, the leaf spring 31 is formed as a curved body that maintains the generatrix parallel to the axis of the hinge pin 29. The two ends of the leaf spring 31 are engaged with the first leaf 27 and the second leaf 28, respectively, at positions away from the hinge pin 29. In the closed position, with the lower end of the upper housing 13 aligned with the upper end of the lower housing 12, the first leaf 27 and the second leaf 28 are arranged along one surface, with the middle region of the leaf spring 31 furthest inward from the hinge pin 29. As the upper housing 13 moves from the closed position to the open position around the hinge pin 29, the angle between the first leaf 27 and the second leaf 28 narrows, and the middle region of the leaf spring 31 approaches the hinge pin 29. Figure 18 As shown, when the middle region of the leaf spring 31 contacts the hinge pin 29, the displacement of the upper housing 13 relative to the lower housing 12 about the hinge pin 29 is restricted, defining the open position of the upper housing 13. When the opening about the hinge pin 29 is less than the defined middle opening, the leaf spring 31 exerts a driving force on the upper housing 13 toward the closed position. When the opening is greater than the defined middle opening, the leaf spring 31 exerts a driving force on the upper housing 13 toward the open position. The hinge 26 and the leaf spring 31 are covered by a hinge cover 32. The hinge cover 32 is formed, for example, from the same raw material as the fabric 18a of the cushioning material 18.

[0118] An LED lamp (light source) 33 emitting ultraviolet light with a predetermined directionality Dv is embedded in the decorative top plate 24a of the upper housing 13. The LED lamp 33 emits, for example, long-wavelength UV-A light (preferably wavelengths of 395nm to 405nm). Preferably, the LED lamp 33 emits only light other than visible light. Preferably, the LED lamp 33 has a narrow directionality Dv. The LED lamp 33 has a directionality Dv that is blocked by the lower housing 12 throughout the illumination area.

[0119] A battery 35 is connected to the LED light 33. The battery 35 is housed in a battery compartment 34 divided between the top plate 16a and the decorative top plate 24a of the resin molded body. The battery 35 can be, for example, a thin button cell battery. Here, for example, multiple button cells are connected in series. Current is supplied from the battery 35 to the LED light 33.

[0120] A switch 36 for controlling the supply and cut-off of current to the LED lamp 33 is assembled on the hinge 26 and the leaf spring 31. A first contact 37, electrically insulated from the leaf spring 31, is fixed in the middle region of the leaf spring 31. The hinge 26 functions as a second contact of the switch 36 in cooperation with the first contact 37. Therefore, the hinge 26 is formed of a conductive material. The first contact 37 is formed of a conductive material, for example, copper. An insulator is sandwiched between the first contact 37 and the leaf spring 31, for example. The first contact 37 is disposed on the leaf spring 31 on the surface opposite to the hinge pin 29. The first contact 37 contacts the hinge 26 in the open position of the upper housing 13 and separates from the hinge 26 outside the open position.

[0121] When fixing the picture frame 103, a magnetic body 66 can be assembled on the upper housing 13. The magnetic body 66 is, for example, made of a thin plate forming the bottom surface of the recess 61. The thin plate can be, for example, a stainless steel plate. The magnet 124 of the picture frame 103 is in contact with the surface of the magnetic body 66. The magnetic force of the magnet 124 binds the picture frame 103 to the magnetic body 66. By the action of the magnet 124, the picture frame 103 is fixed to the recess 61. The picture frame 103 can be well held in the recess 61 regardless of the opening and closing of the upper housing 13.

[0122] like Figure 19 As shown, a light illumination circuit 38, comprising an LED lamp 33, a battery 35, and a switch 36, is constructed within the inner casing 11. In the light illumination circuit 38, the LED element of the LED lamp 33 is connected in series with the battery 35. A timer-limited normally open contact (hereinafter referred to as the "timer contact") 39 is connected in series with the LED lamp 33. The switch 36 and the timer 41 are connected in parallel with the LED lamp 33 and the timer contact 39. When the switch 36 is turned on, the timer 41 operates, and after a predetermined time (hereinafter referred to as the "first time"), the timer contact 39 turns off. As a result, the LED lamp 33 is powered on. When the switch 36 is turned on, the timer 41 is reset, and the timer contact 39 is turned on. As a result, the LED lamp 33 disappears.

[0123] like Figure 20 As shown, a sound reproduction unit 45 for reproducing recorded sound is assembled in the inner casing 11. The sound reproduction unit 45 has a sound circuit 48 that receives sound signals from a microphone 46 and provides sound signals to a speaker 47. A battery 35 is connected to the sound circuit 48. The sound circuit 48 operates by receiving voltage from the battery 35.

[0124] Microphone 46 detects sound-based air vibrations and converts them into sound signals (electrical signals). The generated sound signals are recorded, for example, in memory 49. Memory 49 can be, for example, an EEPROM. Memory 49 can be a memory that allows only one write of the sound signal. Microphone 46 is supported on the upper housing 13 or the lower housing 12. Here, for example, the microphone 46 is housed in a space defined between the top plate 16a and the decorative top plate 24a. Alternatively, through-holes can be formed in the top plate 16a and the decorative top plate 24a, corresponding to the position of the microphone 46 and connecting external gas to the microphone 46.

[0125] The loudspeaker 47 generates air vibrations based on a sound signal and reproduces the corresponding sound. The reproduced sound stimulates the observer's hearing, thus enabling the observer to hear the sound. The loudspeaker 47 is supported by the upper enclosure 13 or the lower enclosure 12. Here, for example, the loudspeaker 47 is housed in the space defined between the top plate 16a and the decorative top plate 24a. Alternatively, the top plate 16a and the decorative top plate 24a may have through holes that correspond to the position of the loudspeaker 47 and connect external air to the loudspeaker 47.

[0126] A retention circuit 51 is connected to the sound reproduction unit 45. This retention circuit 51 retains the sound reproduction from the start of ultraviolet irradiation until a predetermined time (hereinafter referred to as "second time") has elapsed. The retention circuit 51 connects the switch 36 to the sound circuit 48. The battery 35 and the switch 36 are shared in the sound circuit 48 and the light irradiation circuit 38. The retention circuit 51 times (first time + second time) from the moment the switch 36 is turned on. Here, when the predetermined second time has elapsed from the start of ultraviolet irradiation, the sound circuit 48 retrieves the sound signal from the memory 49 and provides it to the speaker 47.

[0127] A recording switch 52 is connected to the sound circuit 48. When the recording switch 52 is turned on, the sound circuit 48 acquires a sound signal from the microphone 46 and stores the sound signal in the memory 49. Figure 21As shown, the button for the recording switch 52 can be located on the inner wall of the upper housing 13. Here, the recording switch 52 is turned on by continuously pressing the button. When the button is released from the pressing operation, the recording switch 52 is turned off. By positioning the button inside the upper housing 13, the recording switch 52 can be protected from accidental operation simply by placing the upper housing 13 in the closed position. The upper housing 13 functions as a protective enclosure against objects outside the structure of the inner housing 11. This prevents unintentional recording of sound (based on overwriting sound erasure). Furthermore, the recording switch 52 can also be linked to the activation of the switch 36. As a result, when the recording switch 52 is operated with the upper housing 13 in the open position, sound can be recorded into the memory 49.

[0128] LED 33, timer contact 39, timer 41, sound circuit 48, memory 49, and retention circuit 51 can also be mounted on a common printed circuit board, for example. The first contact 37 of switch 36, the first leaf 27 or second leaf 28 of hinge 26, battery 35, microphone 46, speaker 47, etc., can simply be electrically connected to the wiring pattern on the printed circuit board via wires such as vinyl-coated wires. The printed circuit board can simply be housed in the battery compartment 34, for example.

[0129] Next, the function of the inner box 11 will be explained. For example... Figure 14 As shown, when the upper housing 13 is in the closed position, the lower edge of the upper housing 13 is aligned with the upper edge of the lower housing 12. The upper housing 13 covers the ring 21 and conceals the diamond bead 23. An observer of the inner housing 11 visually confirms the appearance of the closed inner housing 11. The diamond bead 23 is offset from the observer's field of vision.

[0130] At this time, as Figure 17 As shown, the middle region of the leaf spring 31 is furthest from the hinge pin 29. Therefore, the first contact 37 of the switch 36 separates from the hinge 26, i.e., the second contact. The switch 36 is turned off. The LED light 33 remains off. The operation of the sound circuit 48 remains stopped.

[0131] When an observer moves the upper housing 13 toward the open position against the elastic force of the leaf spring 31 around the hinge pin 29, the lower end of the upper housing 13 exits from the upper end of the lower housing 12. Visible light enters the diamond particle 23 through the gap between the upper housing 13 and the lower housing 12. The diamond particle 23 gradually becomes exposed. The diamond particle 23 is exposed to visible light. Therefore, the diamond particle 23 emits a transparent glow.

[0132] When the opening degree of the upper housing 13 increases beyond the predetermined intermediate opening degree, the leaf spring 31 drives the upper housing 13 toward the open position. As a result, the upper housing 13 reaches the maximum opening position. Based on the elastic force of the leaf spring 31, the upper housing 13 is held in the maximum opening position. The flat surface 63 of the upper housing 13 is located at a position that increases as it moves further away from the axis of rotation. Figure 15 As shown, the observer can visually confirm the diamond grain 23 without being obstructed by the upper housing 13. The diamond grain 23 emits a transparent luster under visible light (natural light or electric light).

[0133] When the upper housing 13 reaches the open position, as Figure 18 As shown, the middle area of ​​the leaf spring 31 is pressed against the hinge pin 29 by the elastic force of the leaf spring 31. Thus, the first contact 37 contacts the hinge 26, i.e., the second contact. The switch 36 is turned on. When a first time has elapsed since the switch 36 was turned on (activated), the LED 33 illuminates. The LED 33 begins to irradiate ultraviolet light onto the diamond particle 23. The diamond particle 23 glows blue.

[0134] After the upper housing 13 is opened, the diamond granules 23, which appear transparent and shiny, are observed to change color from transparent to blue. This creates a light effect based on the opening action of the upper housing 13. The leaf spring 31 provides the driving force to keep the upper housing 13 in the open position, thus preventing the diamond granules 23 from changing color in the middle position between the closed and open positions, allowing the observer to reliably witness the color change of the diamond granules 23.

[0135] When a second time has elapsed since the start of ultraviolet irradiation, the sound circuit 48 reproduces the recorded sound. For example, in the case of a gift, the giver's voice (e.g., "Please get married" or "Let's go together soon") can be transmitted to the observer. The sound reproduction is delayed from the visual effect of the diamond grain 23, so the visual effect of the diamond grain 23 and the sound performance effect act on the observer sequentially. The observer can become aware of the auditory effect of the sound (including speech processing) after becoming aware of the visual effect of the diamond grain 23. The sound performance effect is superimposed on the visual effect. According to the inventor's observation, since multiple senses cannot be perceived simultaneously, the sound reproduction deviates from the visual effect compared to the case where the sound performance effect and visual effect occur simultaneously, thereby enhancing the synergistic effect of vision and sound. Through this performance effect, the observer in the inner box 11 can experience a feeling that cannot be felt under other circumstances.

[0136] When switch 36 is turned off, LED 33 goes out. Sound circuit 48 stops supplying sound signals. Sound reproduction ends.

[0137] The giver's voice is pre-recorded in the inner box 11 before the gift is given. During recording, the upper box 13 is in the open position. The giver presses the recording switch 52 while speaking into the microphone 46 (e.g., "Please get married" or "Let's go together soon"). The sound circuit 48 operates according to the activation of the recording switch 52. The sound is converted into an audio signal by the microphone 46. The audio signal is stored in the memory 49. Recording ends when the finger is removed from the recording switch 52.

[0138] Here, the fabric 18a of the cushioning material 18 can be colored black or dark blue. Due to this coloring, even if visible light adjacent to the ultraviolet region is subtly mixed into the light from the LED light 33, the visible light illuminating the fabric 18a will not be noticeable. The light from the LED light 33 can be excluded from the observer's vision.

[0139] For example, imagine a scene where a man and a woman visit a jewelry store to buy jewelry. The store is filled with the store's or brand's signature scent. Here, the paper 108 in the picture frame 103 could contain aromatic components that help one perceive the store's fragrance. In this way, the store's scent is associated with the inner box 11. When purchasing a ring 21 at the jewelry store, the purchase experience can be linked to the scent. The scent lingers strongly in the memories of both the man and the woman.

[0140] When the inner box 11 was removed from the outer box 192, the scent of a jewelry store wafted around the inner box 11. Figure 22 As shown, the aroma components of the paper 108 leak out from the through-hole 125 into the space 65. The leaked aroma components diffuse upwards from the space 65 toward the upper box 13. The woman can enjoy the fragrance each time she takes out the inner box 11. If the woman accepts the ring 21 as a gift, she will recall the joy of receiving the gift whenever she approaches the inner box 11 in her home. The inner box 11 can create an opportunity to recall the joy of receiving a gift. The male impression can be strongly implanted in the woman.

[0141] The inner box 11 can be used as a source of fragrance in the room. Women can frequently see the inner box 11 in the room. In this way, women can frequently recall the joy of receiving gifts. The male impression can be strongly imprinted on women.

[0142] The surrounding part 64 allows a tray to be formed on the upper surface of the upper box 13. Small items such as rings 21 and keychains can be placed on the plate 111. The surrounding part 64 helps to hold these small items on the plate 111. This tray is used daily, so women can frequently see the inner box 11. The emotions felt when receiving a gift can be strongly imprinted in a woman's memory. It can strongly plant the impression of rings 21, the brand, and the jewelry store where they were purchased in the mind of anyone observing the inner box 11.

[0143] The plate 111 is fixed to the magnetic body 66 using the magnetic force of the magnet 124. Access to the outer periphery of the plate 111 is permitted from the space 65. By applying external force to the outer periphery of the plate 111, it can be easily lifted from the recess 61. The picture frame 103 can be easily removed from the upper box 13. As described above, since the paper 108 can be removed from the picture frame 103, fragrance components can be added to the paper 108. Alternatively, the paper 108 can be replaced with paper fully containing fragrance components. In this way, women can enjoy the fragrance from the inner box 11 at any time. The space 65 can be formed to a size suitable for, for example, accepting the insertion of a ring 21, by extending thinly along the left and right edges of the plate 111. In this case, when removing the picture frame 103, a tool with a rigid body can be inserted into the space 65.

[0144] For example, in a jewelry store, the purchase scene can be captured by an instant camera. The purchase scene can be developed on the spot using instant photoprint (PC). The plate 111 serves to hold the PC within the recess 61. In this way, the PC can be easily installed in the inner case 11. The observer can view the image of the PC through the transparent plate 102. The image can further enhance the emotional experience of receiving a gift.

[0145] In this embodiment, the inner case 11 displays the color change of the diamond grain 23 from transparent to blue fluorescent. The owner of the ring 21 uses the inner case 11 to enjoy the color change of the diamond grain 23. In this way, the inner case 11 is continuously possessed along with the ring 21. The opportunity to remove the inner case 11 is increased. The opportunity to see the image of the instant film is increased. In ordinary products, once the product is used, the packaging box is often discarded.

[0146] Similarly, the inner case 11 of this embodiment reproduces the recorded sound. This achieves a sound performance effect, allowing the owner of the ring 21 to retain the inner case 11 without discarding it and enjoy the sound performance. Thus, the inner case 11 is continuously owned along with the ring 21. The opportunity to remove the inner case 11 is further increased. The opportunity to see the image on the instant film is further increased.

[0147] In this embodiment, the plate 111 of the photo frame 103 is formed into a quadrilateral outline. The plate 111 can be held and held by the wall surfaces that extend parallel to each other within the recess 61. The photo frame 103 not only functions as a photo holder 101 when combined with the auxiliary component 104, but can also be assembled into the inner box 11 of the product packaging unit 191 to add the enjoyment of viewing photos on the product packaging unit 191. The inner box 11 of the product packaging unit 191 can be replaced by a photo frame 173 instead of the photo frame 103.

[0148] like Figure 23As shown, when assembling the picture frame 103, a through-hole 137 extending from the paper compartment and opening on the surface of the plate 111 can also be formed. The lower end of the through-hole 137 overlaps with the paper 108 at a position inside the outline of the paper 108. The aroma components of the paper 108 can diffuse from the through-hole 137 toward the top of the plate 111. The fragrance diffuses around the inner box 11. Here, the magnet 124 can be embedded in the back of the plate 111. The back of the plate 111 can be adjusted to be a single surface.

[0149] Figure 24 The structure of the light illumination circuit of the second specific example is shown in schematic. The light illumination circuit 43 has an NPN transistor TR1 connected to a battery 35. An LED element of an LED lamp 33 is connected between the positive terminal of the battery 35 and the collector C of the NPN transistor TR1. A switch 36 and a first resistor R1 are connected in series between the positive terminal of the battery 35 and the base B of the NPN transistor TR1. A capacitor C1 is connected between the base B of the NPN transistor TR1 and the negative terminal of the battery 35. A second resistor R2 is connected in parallel with the first resistor R1 and the capacitor C1. The emitter E of the NPN transistor TR1 is connected to the negative terminal of the battery 35. In this light illumination circuit 43, when the switch 36 is turned on, the voltage applied to the base B of the NPN transistor TR1 gradually increases through the action of the time constant circuits R1 and C1. During the voltage rise, when the voltage at the base B of the NPN transistor TR1 reaches a predetermined value, current flows into the collector C. Then, after a predetermined time has elapsed, the voltage applied to the base B of the NPN transistor TR1 remains constant. When switch 36 is turned off, the charge in capacitor C1 is discharged through the second resistor R2.

[0150] The retention circuit 51 of the sound reproduction unit 45 retains the sound reproduction until a predetermined time (hereinafter referred to as the "third time") has elapsed after the ultraviolet light reaches its maximum intensity. The battery 35 and switch 36 are shared in the sound circuit 48 and the light irradiation circuit 43. The retention circuit 51 times the time from the turn-on of switch 36 to the time when the ultraviolet light reaches its maximum intensity (hereinafter referred to as the "increment time") and the third time. The increment time can be determined by the voltage characteristics of the light irradiation circuit 43. The increment time corresponds to the time during which the voltage applied to the base B of the NPN transistor TR1 begins to remain at its maximum value after the turn-on of switch 36. Here, when the predetermined third time has elapsed since the moment when the ultraviolet light reaches its maximum intensity, the sound circuit 48 retrieves the sound signal from the memory 49 and provides it to the speaker 47.

[0151] LED 33, NPN transistor TR1, capacitor C1, first and second resistors R1 and R2, sound circuit 48, memory 49, and retention circuit 51 can also be mounted on a common printed circuit board, for example. The first contact 37 of switch 36, the first leaf 27 or second leaf 28 of hinge 26, battery 35, microphone 46, speaker 47, etc., can simply be electrically connected to the wiring pattern on the printed circuit board via wires such as vinyl-coated wires. The printed circuit board can simply be housed in the battery compartment 34, for example.

[0152] In the second specific example of the light illumination circuit 43, after the upper housing 13 reaches the open position and the switch 36 is turned on, after a first period of time has elapsed following the switch 36 being turned on (connection action), a predetermined voltage is applied from the battery 35 to the base B of the NPN transistor TR1. Current flows into the collector C of the NPN transistor TR1, and the LED 33 begins to light up. Therefore, an observer in the inner housing 11 can observe the transparently luminous diamond particle 23 shortly after the upper housing 13 is opened.

[0153] The voltage applied to the base B of the NPN transistor TR1 gradually increases due to the operation of the time constant circuits R1 and C1. The current flowing through the LED 33 gradually increases. The amount of ultraviolet light irradiating the diamond particle 23 from the LED 33 increases. The diamond particle 23 gradually changes color from transparent to blue. Thus, a light display effect is produced according to the opening action of the upper housing 13. The leaf spring 31 provides the driving force to keep the upper housing 13 in the open position, thereby preventing the diamond particle 23 from changing color in the intermediate position between the closed and open positions, allowing the observer to reliably witness the color change of the diamond particle 23.

[0154] When a second time has elapsed since the start of ultraviolet irradiation, that is, when a third time has elapsed since the diamond grain 23 began to glow blue to its maximum, the sound circuit 48 reproduces the recorded sound. For example, if it is a gift, the giver's voice (e.g., "Please get married" or "Let's go together soon") can be delivered to the observer. The reproduction of the sound is delayed from the visual effect of the diamond grain 23, so the visual effect of the diamond grain 23 and the performance effect of the sound act on the observer in sequence. The observer can perceive the auditory effect of the sound (including speech processing) after perceiving the visual effect of the diamond grain 23. The performance effect of the sound is superimposed on the visual effect. According to the inventor's observation, since multiple senses cannot be perceived simultaneously, the reproduction of the sound deviates from the visual effect compared to the case where the performance effect of the sound and the visual effect occur simultaneously, thereby enhancing the synergistic effect of vision and sound. Through this performance effect, the observer in the inner box 11 can experience a feeling that cannot be felt under other circumstances.

[0155] When switch 36 is turned off, LED 33 goes out. Sound circuit 48 stops supplying sound signals. Sound reproduction ends. The charge in capacitor C1 is discharged through the second resistor R2.

[0156] Alternatively, the LED light 33 can replace the upper housing 13 and be supported on the lower housing 12. Furthermore, the diamond beads 23 can be mounted on multiple pedestals forming the chain of a necklace. These pedestals are made of metals such as platinum or gold. One or more diamond beads 23 can be fixed to each pedestal. Additionally, the diamond beads 23 can be used as decoration on pendants, bracelets, earrings, hoops, and anklets. The diamond beads can be of uniform size or a mixture of sizes.

[0157] In the aforementioned inner casing 11, switch 36 can also be a tactile switch having a plunger pressed down by the upper casing 13 when it reaches the open position. The light illumination circuit 38 in the first embodiment and the light illumination circuit 43 in the second embodiment can be replaced with other electronic circuit structures as long as they achieve the same function as described above. Furthermore, the operation of switch 36 can be linked not only to the upper casing 13 in the open position as described above, but also to the upper casing 13 in the closed position. In addition, the functions of the light illumination circuits 38 and 43, the sound circuit 48, and the hold circuit 51 can also be implemented by software executed by a microprocessor (MPU).
