Description

[Technical field]

[0001] The present invention relates to a photo frame that includes a plate defining a plane for receiving a photograph, and a holder that is attached to the plate and conforms to the plane to hold the photograph. [Background technology]

[0002] For example, Patent Documents 1 and 2 disclose structures that associate a scent with a photograph displayed in a photo frame. In Patent Document 1, a fragrance is stored in a container. The container is attached to a window hole drilled in the back panel of the frame. The fragrance components of the fragrance dissipate from small holes in the container. In Patent Document 2, a thin sheet of fragrance body is inserted into the frame. The fragrance body has a thin sheet of fragrance absorbent sandwiched between cardboard. The surface of the cardboard is covered with a PVC film barrier. To replenish the fragrance, the fragrance body is removed from the frame. The fragrance body is immersed in a solution of the fragrance components. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 3-114413 [Patent Document 2] JP 2001-54452 A [Patent Document 3] Registered Utility Model No. 3161407 Summary of the Invention [Problem to be solved by the invention]

[0004] If different scents could be selected depending on one's mood at any given time, photographs would provide even more enjoyment to the viewer. In Patent Document 1, to change the air freshener, the frame is opened on a hinge. After opening, the container is removed from the back panel. The air freshener can be changed by opening and closing the container. This requires a lot of work for such a small pleasure as changing scents. In Patent Document 2, the entire scent body (= absorbent material + cardboard + PVC film) is replaced to change scents. The new scent body is immersed in a solution of a different fragrance component. This requires a lot of work for such a small pleasure as changing scents.

[0005] An object of the present invention is to provide a photo frame that diffuses fragrances and allows the fragrance to be easily switched. [Means for solving the problem]

[0006] According to one form of the present invention, a photo frame is provided comprising: a long piece of paper containing an aromatic component; a plate defining a first plane on the front or back for receiving a photograph and a second plane on the back for receiving the piece of paper; a first holder attached to the plate and holding the photograph in line with the first plane; and a second holder attached freely detachably to the plate and holding the piece of paper in line with the second plane.

[0007] When the second holder is removed from the plate, the piece of paper can be separated from the plate by itself. Since the piece of paper is itself an absorbent for the fragrance, the fragrance only needs to soak into the piece of paper. For example, the fragrance can be sprayed onto the piece of paper, like perfume. The fragrance can be replenished in a short time without any hassle. The fragrance can be easily switched to another fragrance by replacing the piece of paper by itself. A different fragrance, like perfume, can be sprayed onto a new piece of paper. Moreover, since the photograph and the piece of paper are held separately on the first plane and the second plane, the piece of paper is positioned away from the photograph. Contact between the photograph and the piece of paper can be effectively avoided. The fragrance can be prevented from soaking into the photograph from the piece of paper.

[0008] The plate may be a resin plate that defines the first plane and the second plane on the back surface and has a transparent area that covers at least the photographic image. An observer can observe the photographic image through the transparent area. The plate can protect the photographic image while ensuring the visibility of the image. Here, the first holder can be maintained on the plate when the second holder is removed. The photograph can continue to be held on the plate when the piece of paper is replaced. Misalignment of the photograph can be avoided when the piece of paper is replaced.

[0009] The second holder may be a slider that is guided by a pair of rails that extend linearly parallel to both sides of the second plane and displaces between a first position where the second holder holds the piece of paper in accordance with the second plane and a second position where the second holder is released from the second plane. Since the rails are disposed on the rear surface of the plate, the surface of the plate can be maintained as a smooth surface. The visibility of the image can be maintained well. The piece of paper can be removed from the plate in response to the displacement of the second holder. Here, the second holder can be formed with an outward surface that is flush with the rails. In this way, the shape of the rear surface of the plate can be adjusted.

[0010] The plate may be made of a transparent material, and an opaque film may be formed on the surface of the plate to cover at least the edge of the photograph. The plate may be molded from a single transparent material. The plate may be molded in a simple process. Inexpensive molding may be achieved. Meanwhile, since the edge of the photograph is hidden by the opaque film, the image may be well highlighted.

[0011] The first holder may be a slider that is guided by a pair of rails extending parallel to both sides of the first plane and displaces between a first position where the photograph is held along the first plane and a second position where the photograph is removed from the first plane. Since the rails are disposed on the back surface of the plate, the surface of the plate can be maintained as a smooth surface. The visibility of the image can be maintained well. The photograph can be removed from the plate in response to the displacement of the first holder. Here, the first holder can be formed with an outward surface that is flush with the rails. In this way, the shape of the back surface of the plate can be adjusted.

[0012] The plate may define the first plane on the front surface and the second plane on the rear surface, the first holder may be placed on the front surface of the plate to sandwich and hold the photograph between the plate and the first holder, and the second holder may be placed on the rear surface of the plate to sandwich and hold the piece of paper between the plate and the first holder. The photograph and the piece of paper are physically separated by the plate. Contact between the photograph and the piece of paper can be effectively avoided. Permeation of the aroma components from the piece of paper into the photograph can be prevented. Moreover, the photograph can be kept away from the path of the vaporized aroma components. Transfer of the aroma components from the piece of paper to the photograph can also be effectively prevented.

[0013] The piece of paper may be disposed inside the outline of the photograph projected onto the rear surface in a direction perpendicular to the front surface of the plate. Since the piece of paper is disposed behind the photograph, the piece of paper can be hidden by the photograph from the front side even if the first holder and the plate are both formed from a single transparent material. The image of the photograph can be well highlighted.

[0014] The plate may be formed into a rectangular shape. The plate may be sandwiched between walls extending parallel to each other. The photo frame can be combined with other members to function as a photo stand, and can also be attached to other types of items to add the enjoyment of viewing photos to the items. Effect of the Invention

[0015] As described above, according to the present invention, a photo frame that diffuses fragrances and allows the fragrance to be easily switched can be provided. [Brief description of the drawings]

[0017] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

[0018] FIG. 1 shows a schematic diagram of a photo stand according to a first embodiment of the present invention. The photo stand 101 includes a photo frame 103 that displays an image of a photo PC through a transparent plate 102 while diffusing a fragrance, and an auxiliary member 104 that holds the photo frame 103 in an upright position on a horizontal surface PL. For the photo PC, photo prints printed on paper, instant films with white margins around the image, and other materials can be used. Here, the auxiliary member 104 includes a flat plate 105 that receives the photo frame 103, and a leg plate 106 that is connected to the lower edge of the flat plate 105 and overlaps the horizontal surface PL. The flat plate 105 and the leg plate 106 can be formed by bending, for example, a single metal plate (for example, a stainless steel plate). Thus, the leg plate 106 is continuous with the lower end of the flat plate 105 at the front end. The flat plate 105 only needs to be made of at least a magnetic material. The front end of the leg plate 106 is located forward of the center of gravity of the flat plate 105 and the photo frame 103, and the rear end of the leg plate 106 is located rearward of the center of gravity of the flat plate 105 and the photo frame 103, so that the leg plate 106 can support the flat plate 105 in an upright position on the horizontal plane PL. Here, the flat plate 105 tilts backward at a specific angle around its lower end.

[0019] As shown in FIG. 2, the photo frame 103 has a plate 111 on the back side that defines a first plane 107 for receiving a photo PC and a second plane 109 for receiving a piece of paper 108. The second plane 109 is arranged without overlapping the first plane 107. The second plane 109 is separated from the first plane 107. The plate 111 can be made of a transparent body as a whole, for example. The transparent body can be molded from a hard acrylic resin, for example. The plate 111 is formed from a material that blocks ventilation (non-breathable material). Here, an opaque film 112 that covers at least the edge of the photo PC is formed on the surface of the plate 111. The opaque film 112 extends to the outer edge of the plate 111 all around, surrounding a window 113 that shows an image of the photo PC, for example. Therefore, the plate 111 forms a transparent area (transparent plate 102) that covers at least the image of the photo PC in correspondence with the window 113. The viewer can view the image of the photo PC through the transparent area. The opaque film 112 can be made of, for example, a colored painted film.

[0020] Photo frame 103 includes first holder 114 attached to plate material 111 and holding photo PC along first plane 107. First holder 114 is a slider that is guided by a pair of first rails 116 extending parallel to both sides of first plane 107 and displaces between a first position where it holds photo PC along first plane 107 and a second position where it is removed from first plane 107. Therefore, first holder 114 is attached to plate material 111 in a detachable manner.

[0021] The first rail 116 extends linearly horizontally. A first smooth surface 117 is defined between the first rails 116 on the back surface of the plate material 111. The first rail 116 defines a guideway in contact with the first smooth surface 117. When defining the guideway, the first rail 116 forms a restricting edge 116a for receiving the first holder 114 between the first rail 116 and the first smooth surface 117. The restricting edge 116a allows the first holder 114 to move horizontally along the guideway while restricting the first holder 114 from being separated from the first plane 107 by a movement other than the horizontal movement. Here, the first plane 107 is defined by the inner surface of a recess 118 drilled in the first smooth surface 117. The recess 118 is closed by the first holder 114 overlapping the first smooth surface 117 at the first position, and defines a photo room for accommodating a photo PC between the first holder 114 and the first plane 107. The contour of the recess 118 may be matched to the contour of the photograph PC.

[0022] The first holder (slider) 114 is formed as a flat plate that blocks the entire guideway at the first position. The upper edge of the flat plate engages with the restricting edge 116a of the upper first rail 116. The lower edge of the flat plate engages with the restricting edge 116a of the lower first rail 116. The first holder (slider) 114 may be molded from, for example, a hard acrylic resin. The first holder 114 is formed from a material that blocks air (non-breathable material).

[0023] Photo frame 103 is equipped with second holder 115 which is attached to plate material 111 and holds piece of paper 108 following second plane 109. Second holder 115 is a slider which is guided by a pair of second rails 121 extending parallel to both sides of second plane 109 and displaces between a first position where it holds piece of paper 108 following second plane 109, and a second position where it is removed from second plane 109. Therefore, second holder 115 is attached to plate material 111 in a detachable manner.

[0024] The second rail 121 extends linearly horizontally. A second smooth surface 122 is defined between the second rails 121 on the back surface of the plate material 111. The second rail 121 defines a guideway in contact with the second smooth surface 122. When defining the guideway, the second rail 121 forms a restricting edge 121a between the second smooth surface 122 and the second rail 121 to receive the second holder 115. The restricting edge 121a allows the second holder 115 to move horizontally along the guideway while restricting the second holder 115 from leaving the second plane 109 in any manner other than horizontal movement. Here, the second plane 109 is defined by the inner surface of a recess 123 drilled in the second smooth surface 122. The recess 123 is closed by the second holder 115 that overlaps the second smooth surface 122 at the first position, and defines a paper piece chamber for storing the paper piece 108 between the second holder 115 and the second plane 109.

[0025] The second holder (slider) 115 is formed as a flat plate that blocks the entire guideway in the first position. The upper edge of the flat plate engages with the restricting edge 121a of the upper second rail 121. The lower edge of the flat plate engages with the restricting edge 121a of the lower second rail 121. The second holder (slider) 115 may be molded from, for example, a hard acrylic resin. The second holder 115 is formed from a material that blocks air (non-breathable material).

[0026] The piece of paper 108 contains an aroma component. The piece of paper 108 is formed long in the horizontal direction. The contour of the depression 123 may be set to match the contour of the piece of paper 108. The piece of paper 108 has an absorbency for retaining a solvent for the aroma component. The piece of paper 108 can be soaked in perfume, for example. The piece of paper 108 may be made of a paper material that changes color in response to the absorption of the aroma component. For example, litmus paper can change color in response to the pH, which changes in response to the absorption of the aroma component.

[0027] As shown in Fig. 3, a magnet 124 is fixed to the back surface of the plate material 111 at a position offset from the guide path defined by the first rail 116 and the second rail 121. When the photo frame 103 is received on the flat plate 105 of the auxiliary member 104, the magnet 124 comes into surface contact with the surface of the flat plate 105. The photo frame 103 is held on the flat plate 105 by the action of magnetic force. The magnet 124 protrudes at a determined height from a plane including the back surface of the plate material 111. The magnet 124 forms a gap Hs between the second holder 115 and the flat plate 105 of the auxiliary member 104. The gap Hs is open to the atmosphere at the outer periphery of the plate material 111.

[0028] As shown in Fig. 4, the second holder 115 has a through hole 125 that connects the paper piece chamber to the outside space. The aromatic components of the paper piece 108 can be diffused into the outside space through the through hole 125. The distance Hs between the second holder 115 and the flat plate 105 connects the through hole 125 to the atmosphere. Alternatively, the through hole may be drilled in the plate material 111 to connect the paper piece chamber to the outside space.

[0029] Alternatively, as shown in FIG. 5, the first plane 107 and the second plane 109 may be formed flush with the rear surface of the plate material 111. Here, the first plane 107 is included in the first smooth surface 117. A recess 118 is formed in the first holder 114 at a position overlapping the first plane 107. The first smooth surface 117 (first plane 107) closes the recess 118 at the first position of the first holder 114. In this way, a photo room for accommodating a photo PC is defined between the first holder 114 and the first plane 107. Similarly, the second plane 109 is included in the second smooth surface 122. A recess 123 is formed in the second holder 115 at a position overlapping the second plane 109. The second smooth surface 122 (second plane 109) closes the recess 123 at the first position of the second holder 115. In this way, a paper chamber for storing the paper piece 108 is defined between the second holder 115 and the second flat surface 109. Similarly, the second holder 115 has a through hole 125 that connects the paper chamber to the outside space. The aromatic components of the paper piece 108 can be diffused into the outside space from the through hole 125. The distance Hs between the second holder 115 and the flat plate 105 connects the through hole 125 to the atmosphere.

[0030] As shown in FIG. 6, the auxiliary member 104 may further include a positioning piece 126 disposed between the flat plate 105 and the leg plate 106 to receive the lower edge of the photo frame 103. When the lower edge of the photo frame 103 is placed against the positioning piece 126, the lower edge of the photo frame 103 can be horizontally positioned. The position of the photo frame 103 can be set prior to the fixation based on magnetic force. The positioning piece 126 may protrude forward from the surface of the flat plate 105. When the flat plate 105 and the leg plate 106 are formed from a single metal plate, the positioning piece 126 can be established between the flat plate 105 and the leg plate 106 by bending. The front end of the leg plate 106 is located forward of the center of gravity of the flat plate 105 and the photo frame 103, and the rear end of the leg plate 106 is located rearward of the center of gravity of the flat plate 105 and the photo frame 103, so that the leg plate 106 can support the flat plate 105 in an upright position on the horizontal plane PL.

[0031] Next, the operation of the photo stand 101 according to the first embodiment will be described. The photo stand 101 is placed on a horizontal surface PL of a desk, shelf, or other piece of furniture. The legs 106 of the auxiliary member 104 are placed on the horizontal surface PL. The flat plate 105 is placed in an upright position on the horizontal surface PL. The photo frame 103 is fixed to the flat plate 105. The magnets 124 connect the photo frame 103 to the flat plate 105. The image on the photo PC is displayed forward through the transparent plate 102. The viewer can enjoy viewing the image. Since the photo frame 103 is connected to the auxiliary member 104 by magnetic force, the photo frame 103 can be easily removed from the auxiliary member 104.

[0032] The aroma components dissipate from the piece of paper 108. The aroma components flow out of the through-hole 125 into the external space of the paper chamber. The aroma components pass through the gap Hs between the second holder 115 and the flat plate 105 and diffuse into the atmosphere from the periphery of the photo frame 103. In this way, the observer can enjoy the aroma while viewing the image. Visual sensitivity can be enhanced by olfactory sensitivity. When past visual information is linked to the aroma in the observer's memory, the observer can be immersed in a revived sense of presence.

[0033] When replacing the photo PC, the photo frame 103 is removed from the auxiliary member 104. In the photo frame 103, the first holder 114 is removed from the plate material 111. The first holder 114 is driven along the guide path from the first position to the second position. The photo chamber is opened. The photo PC is removed from the recess 118. In this way, the photo PC can be separated from the plate material 111 as a single unit.

[0034] A new photo PC is set in the recess 118. The photo PC is superimposed on the first plane 107. The image on the photo PC is aligned with the transparent plate 102. A first holder 114 is attached to the plate material 111. The first holder 114 is driven along the guideway from the second position to the first position. The first holder 114 closes the photo chamber. The photo PC can now be replaced.

[0035] A user of the photo stand 101 can replenish the piece of paper 108 with fragrance. To replenish the fragrance, the photo frame 103 is removed from the auxiliary member 104. In the photo frame 103, the second holder 115 is removed from the plate material 111. The second holder 115 is driven along the guide path from the first position to the second position. The paper chamber is opened. The piece of paper 108 is removed from the recess 123. In this way, the piece of paper 108 can be pulled away from the plate material 111 as a single piece. To replenish the fragrance, the user may immerse the piece of paper 108 in a liquid containing the fragrance, or may spray the liquid containing the fragrance (e.g., perfume) onto the piece of paper 108.

[0036] The piece of paper 108 is set in the recess 123. The piece of paper 108 is placed on the second plane 109. A second holder 115 is attached to the plate material 111. The second holder 115 is driven along a guide path from the second position to the first position. The second holder 115 closes the paper chamber. In this way, the fragrance component can be replenished to the piece of paper 108. Even if the fragrance disappears once, the user can enjoy the fragrance again by refilling. Even if the fragrance weakens, it can be strengthened by refilling.

[0037] When the second holder 115 is removed from the plate material 111, the piece of paper 108 can be pulled off from the plate material 111 as a single piece. Since the piece of paper 108 is itself an absorbent for the fragrance components, the fragrance components only need to soak into the piece of paper 108. For example, the fragrance components can be sprayed onto the piece of paper, like perfume. The fragrance components can be replenished in a short time and without hassle. Furthermore, the scent can be easily switched to another scent by replacing the piece of paper 108 alone. A different fragrance component, like perfume, can be sprayed onto a new piece of paper 108.

[0038] Moreover, since the photo PC and the piece of paper 108 are individually held on the first plane 107 and the second plane 109, the piece of paper 108 is positioned away from the photo PC. Contact between the photo PC and the piece of paper 108 can be effectively avoided. Permeation of aroma components from the piece of paper 108 into the photo PC can be prevented.

[0039] The plate material 111 of this embodiment is a resin plate that defines a first plane 107 and a second plane 109 on the back surface and has a transparent area that covers the image of the photo PC. An observer can view the image of the photo PC through the transparent area. The plate material 111 can protect the image of the photo PC while ensuring the visibility of the image. Here, the first holder 114 can be maintained on the plate material 111 when the second holder 115 is removed. When the piece of paper 108 is replaced, the photo PC can continue to be held as it is on the plate material 111. Misalignment of the photo PC can be avoided when the piece of paper 108 is replaced.

[0040] In this embodiment, the second holder 115 is a slider that is guided by a pair of second rails 121 that extend linearly parallel to both sides of the second plane 109, and displaces between a first position where the second holder 115 holds the piece of paper 108 along the second plane 109, and a second position where the second holder 115 is released from the second plane 109. Since the second rails 121 are disposed on the back surface of the plate material 111, the surface of the plate material 111 can be maintained as a smooth surface. The visibility of the image can be maintained well. The piece of paper 108 can be removed from the plate material 111 according to the displacement of the second holder 115. Here, the second holder 115 can be formed with an outward surface that is flush with the second rails 121. In this way, the shape of the back surface of the plate material 111 can be adjusted.

[0041] As described above, the plate material 111 is made of a transparent body. An opaque film 112 that covers and hides the edges of the photograph PC is formed on the surface of the plate material 111. The plate material 111 can be molded from a single transparent material. The plate material 111 can be molded in a simple process. Low-cost molding can be achieved. Meanwhile, since the edges of the photograph PC are hidden by the opaque film 112, the image can be well highlighted.

[0042] The first holder 114 is a slider that is guided by a pair of first rails 116 extending parallel to both sides of the first plane 107, and displaces between a first position where the first holder 114 holds the photo PC following the first plane 107, and a second position where the first holder 114 is removed from the first plane 107. Since the first rails 116 are disposed on the back surface of the plate material 111, the surface of the plate material 111 can be maintained as a smooth surface. The visibility of the image can be maintained well. The photo PC can be removed from the plate material 111 according to the displacement of the first holder 114. Here, the first holder 114 can be formed with an outward surface that is flush with the first rails 116. In this way, the shape of the back surface of the plate material 111 can be adjusted.

[0043] As shown in Fig. 7, instead of the above-mentioned auxiliary member 104, the auxiliary member 131 may be a shaft body 132 attached to the plate material 111 and extending rearward from the back surface of the plate material 111. The shaft body 132 has, for example, a screw shaft 133 having an axis perpendicular to the back surface of the plate material 111. The shaft body 132 may be formed, for example, as a cylindrical body coaxial with the screw shaft 133. The screw shaft 133 is screwed into the back surface of the plate material 111. In this way, the shaft body 132 can be detachably fixed to the plate material 111 by engaging the screw. The shaft body 132 can be formed from a metal material such as aluminum.

[0044] According to the shaft body 132, the photo frame 103 is supported on the horizontal plane PL at the rear lower end of the plate material 111, and the rear end of the shaft body 132 is supported on the horizontal plane PL. The rear lower end of the plate material 111 is located forward of the center of gravity of the photo frame 103, and the rear end of the shaft body 132 is located rearward of the center of gravity of the photo frame 103, so that the shaft body 132 can support the photo frame 103 in an upright position on the horizontal plane PL. Here, the photo frame 103 tilts backward at a specific angle around the rear lower end.

[0045] As shown in FIG. 8, instead of the above-mentioned auxiliary members 104 and 131, the auxiliary member 134 may be a weight 135 placed on a horizontal plane PL. The weight 135 may be, for example, a block of stainless steel or other metal with a specific gravity of 7 or more, molded into a rectangular parallelepiped. A linear groove 136 extending horizontally is formed on the upper surface of the weight 135. For example, the lower end of the photo frame 103 can be inserted into the groove 136 from above. At this time, the centers of gravity of the weight 135 and the photo frame 103 are located within the contact area between the weight 135 and the horizontal plane PL. As a result, the weight 135 can hold the photo frame 103 in an upright position on the horizontal plane PL.

[0046] FIG. 9 shows a schematic diagram of a photo stand according to the second embodiment. The photo stand 141 includes a photo frame 143 that diffuses a scent while presenting an image of a 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. For the photo PC, a photo print printed on paper, an instant film including a white margin around the image, or the like can be used. The transparent plate 142 can be made of, for example, a glass plate. The photo PC is superimposed on the back surface of the transparent plate 142. A frame body 146 that defines a window 145 through which the image of the photo PC is displayed is superimposed on the front surface of the transparent plate 142. The frame body 146 can be molded from an opaque hard resin material or wood. The frame body 146 covers the edge of the transparent plate 142 over the entire periphery of the transparent plate 142. An observer can observe the image of the photo PC through the transparent plate 142.

[0047] As shown in FIG. 10, the photo frame 143 includes a plate member 153 that defines a first plane 151 on the front side for receiving a photo PC and defines a second plane 152 on the back side for receiving a long piece of paper 108 containing an aromatic component. The second plane 152 is separated from the first plane 151. The plate member 153 can be made of an opaque body as a whole. The plate member 153 can be molded from an opaque hard resin material or wood, for example. The plate member 153 is made of a material that blocks air (non-breathable material). When the plate member 153 is fitted into the frame body 146 from the back, the first plane 151 presses the photo PC against the back side of the transparent plate 142. In this way, the photo PC is held following the first plane 151. The frame body 146 and the transparent plate 142 cooperate to form a first holder according to the present invention.

[0048] Fasteners 154 are attached to frame 146 to hold plate 153 fitted into frame 146. Fasteners 154 are displaceable between a first position where they engage with the rear surface of fitted plate 153 from behind, and a second position where they rotate from the first position about rotation axis 155 and are disengaged from plate 153. When all fasteners 154 are disengaged from plate 153 at the second position, plate 153 can be removed from frame 146. The photo PC can be replaced upon removal of plate 153.

[0049] The photo frame 143 further includes a second holder 156 that is detachably attached to the plate 153 and holds the piece of paper 108 following the second plane 152. The second holder 156 is a slider that is guided by a pair of slide rails 157 that extend parallel to both sides of the second plane 152 and displaces between a first position where the second holder 156 holds the piece of paper 108 following the second plane 152 and a second position where the second holder 156 is removed from the second plane 152. The slide rails 157 extend horizontally and linearly. A smooth surface 158 is defined on the back surface of the plate 153 between the slide rails 157. The slide rails 157 define a guideway that is in contact with the smooth surface 158. When defining the guideway, the slide rails 157 form a regulating edge 157a that receives the second holder 156 between the smooth surfaces 158. The restricting edge 157a allows the second holding body 156 to move horizontally along the guide path, while restricting the second holding body 156 from leaving the second plane 152 in any manner other than the horizontal movement. At this time, a guide path 159 that is continuous with the guide path and opens at the periphery of the frame body 146 is defined in the frame body 146. The second holding body 156 passes through the guide path 159 when displacing in the horizontal direction.

[0050] Here, the second plane 152 is defined by the inner surface of a recess 161 drilled in the smooth surface 158. The recess 161 is blocked by a second holder 156 that overlaps the smooth surface 158 in the first position, and defines a paper piece chamber for accommodating the paper piece 108 between the second holder 156 and the second plane 152. The second holder (slider) 156 is formed as a flat plate that blocks the entire guide path in the first position. The upper edge of the flat plate engages with a regulating edge 157a of the upper slide rail 157. The lower edge of the flat plate engages with a regulating edge 157a of the lower slide rail 157.

[0051] The second holder (slider) 156 can be molded from, for example, a hard acrylic resin. The second holder 156 is formed from a material that blocks air (non-breathable material). The second holder 156 has a through hole 162 that connects the paper piece chamber to the outside space. The aroma components of the paper piece 108 can be diffused from the through hole 162 to the outside space.

[0052] The auxiliary member 144 is attached to the plate material 153 and includes a support leg 164 that is displaceable between a first position where the support leg 164 overlaps the plate material 153 and a second position where the support leg 164 rotates from the first position about the rotation axis 163 and is separated from the plate material 153 at a determined angle about the rotation axis 163. The support leg 164 may be formed, for example, of a polygonal flat plate that overlaps the plate material 153. The support leg 164 defines a first edge 164a that extends linearly parallel to the lower end of the frame body 146 at a position away from the rotation axis 163, and a second edge 164b that extends linearly parallel to the side end of the frame body 146 at a position away from the rotation axis 163.

[0053] As with a general photo stand, when the lower end of the frame body 146 is supported on the horizontal plane PL and the supporting leg 164 at the second position is supported on the horizontal plane PL by the first edge 164a, the supporting leg 164 can hold the photo frame 143 in a vertically upright position on the horizontal plane PL. At this time, the frame body 146 tilts backward at a specific angle around the lower end. The lower end of the frame body 146 is located forward of the center of gravity of the photo frame 143, and the first edge 164a of the supporting leg 164 is located rearward of the center of gravity of the photo frame 143. When the side end of the frame body 146 is supported on the horizontal plane PL and the supporting leg 164 at the second position is supported on the horizontal plane PL by the second edge 164b, the supporting leg 164 can hold the photo frame 143 in a horizontally upright position on the horizontal plane PL. At this time, the frame body 146 tilts backward at a specific angle around the side end. The side end of the frame 146 is located forward of the center of gravity of the photo frame 143, and the second edge 164b of the supporting leg 164 is located rearward of the center of gravity of the photo frame 143.

[0054] Like a general photo stand, the photo frame 143 may include a first keyhole member 166 and a second keyhole member 167 for wall hanging. The first keyhole member 166 and the second keyhole member 167 are attached to the frame body 146. Alternatively, the first keyhole member 166 and the second keyhole member 167 may be attached to the back surface of the plate material 153. The first keyhole member 166 has an elongated hole 166a extending in a vertical direction relative to the vertically oriented frame body 146, and an enlarged diameter entrance hole 166b continuing to the lower end of the elongated hole 166a in the direction of gravity. Similarly, the second keyhole member 167 has an elongated hole 167a extending in a vertical direction relative to the horizontally oriented frame body 146, and an enlarged diameter entrance hole 167b continuing to the lower end of the elongated hole 167a in the direction of gravity. The wall fitting (not shown) may include a shaft extending horizontally perpendicular to the wall and guided along the long holes 166a, 167a, and an enlarged head connected to the tip of the shaft to allow it to move in and out of the entry holes 166b, 167b while preventing it from slipping out of the long holes 166a, 167a.

[0055] Next, the operation of the photo stand 141 according to the second embodiment will be described. The photo stand 141 is installed on a horizontal plane PL of a desk, a shelf, or other furniture. For example, in the case of a portrait photo PC, the lower end of the frame body 146 and the first edge 164a of the support leg 164 are supported on the horizontal plane PL. When installed in this manner, the support leg 164 is restricted to a second position around the rotation axis 163. The frame body 146 is placed in an upright position on the horizontal plane PL. An image of the photo PC is displayed forward through the transparent plate 142. The observer can enjoy viewing the image. In the case of a landscape photo PC, the side end of the frame body 146 and the second edge 164b of the support leg 164 are supported on the horizontal plane PL.

[0056] The aroma components dissipate from the paper piece 108. The aroma components flow out of the through-hole 162 into the space outside the paper piece chamber. The aroma components diffuse into the atmosphere. In this way, the viewer can enjoy the aroma while viewing the image. Visual sensitivity can be enhanced by olfactory sensitivity. When past visual information is linked to the aroma in the viewer's memory, the viewer can be immersed in a revived sense of presence.

[0057] When replacing the photograph PC, the plate material 153 is removed from the frame 146. When removing, the fastener 154 is driven from a first position to a second position about a rotation axis 155. In response to the removal, the plate material 153 is pulled away from the photograph PC. The second holder 156 is maintained on the plate material 153. The photograph PC is peeled off from the back surface of the transparent plate 142. The transparent plate 142 can remain on the frame 146.

[0058] A new photo PC is set in the frame 146 from the rear. The photo PC is superimposed on the transparent plate 142. The image on the photo PC is aligned with the window 145 in the frame 146. A plate material 153 is attached to the frame 146. During attachment, the fasteners 154 are driven from the second position to the first position around the rotation axis 155. In this way, the photo PC can be replaced.

[0059] A user of the photo stand 141 can replenish the piece of paper 108 with fragrance. When replenishing the fragrance, the connection between the plate 153 and the frame 146 can be maintained. The second holder 156 is removed from the plate 153. The second holder 156 is driven along a guide path from a first position to a second position. The paper chamber is opened. The piece of paper 108 is removed from the recess 161. In this way, the piece of paper 108 can be pulled away from the plate 153 as a single piece. When replenishing the fragrance, the user may immerse the piece of paper 108 in a liquid containing the fragrance, or may spray the liquid containing the fragrance (e.g., perfume) onto the piece of paper 108.

[0060] The piece of paper 108 is set in the recess 161. The piece of paper 108 is placed on the second plane 152. A second holder 156 is attached to the plate material 153. The second holder 156 is driven along a guide path from the second position to the first position. The second holder 156 closes the paper chamber. In this way, the fragrance component can be replenished to the piece of paper 108. Even if the fragrance disappears once, the user can enjoy the fragrance again by refilling. Even if the fragrance weakens, it can be strengthened by refilling.

[0061] When the second holder 156 is removed from the plate 153, the piece of paper 108 can be pulled off from the plate 153 as a single piece. Since the piece of paper 108 is itself an absorbent for the fragrance components, the fragrance components only need to soak into the piece of paper 108. For example, the fragrance components can be sprayed onto the piece of paper, like perfume. The fragrance components can be replenished in a short time and without hassle. Furthermore, the fragrance can be easily switched to another fragrance by simply replacing the piece of paper 108 as a single piece. A different fragrance component, like perfume, can be sprayed onto a new piece of paper 108.

[0062] The plate material 153 of this embodiment defines a first plane 151 on the front surface and a second plane 152 on the rear surface. The transparent plate 142 of the first holder is placed on the front surface of the plate material 153 to sandwich and hold the photograph PC between the plate material 153. The second holder 156 is placed on the rear surface of the plate material 153 to sandwich and hold the piece of paper 108 between the plate material 153. The photograph PC and the piece of paper 108 are physically separated by the plate material 153. Contact between the photograph PC and the piece of paper 108 can be effectively avoided. The permeation of the aroma components from the piece of paper 108 into the photograph PC can be prevented. Moreover, the photograph PC can be kept away from the path of the vaporized aroma components. The transfer of the aroma components from the piece of paper 108 to the photograph PC can also be effectively prevented.

[0063] The support legs 164 and the keyhole members 166 and 167 may be attached to a magnetic flat plate. For example, the photo frame 103 can be fixed to the flat plate in response to the magnetic force of the magnet 124. For example, in a portrait photo PC, the lower end of the flat plate and the first edge 164a of the support legs 164 may be supported on the horizontal plane PL. When installed in this manner, the support legs 164 are restricted to a second position around the rotation axis 163. The frame body 146 is placed in an upright position on the horizontal plane PL. The image of the photo PC is displayed forward through the transparent plate 102. The viewer can enjoy viewing the image. In the case of a landscape photo PC, the side end of the flat plate and the second edge 164b of the support legs 164 may be supported on the horizontal plane PL.

[0064] FIG. 11 shows a schematic diagram of a photo frame used in a photo stand according to the third embodiment. The photo frame 173 of this embodiment can be combined with the above-mentioned auxiliary member 104 to form the photo stand 101. The photo frame 173 includes a plate member 176 that defines a first plane 174 for receiving a photo PC on the front side and a second plane 175 for receiving a piece of paper 108 on the back side. The second plane 175 is separated from the first plane 174. The plate member 176 can be made of a transparent body as a whole, for example. The transparent body can be molded from a hard acrylic resin, for example. Alternatively, the plate member 176 can be made of an opaque material. The plate member 176 is made of a material that blocks ventilation (non-breathable material).

[0065] The photo frame 173 further includes a first holder 177 that is detachably attached to the plate 176 and holds the photo PC following the first plane 174, and a second holder 178 that is detachably attached to the plate 176 and holds the piece of paper 108 following the second plane 175. The first holder 177 is placed on the surface of the plate 176 to sandwich and hold the photo PC between the plate 176. The first holder 177 can be made of a transparent body as a whole, for example. The transparent body can be molded from a hard acrylic resin, for example. The viewer can view the image of the photo PC through the first holder 177. Here, the outline of the first holder 177 is placed on the outline of the plate 176. Therefore, the first holder 177 and the plate 176 can be recognized as one rectangular parallelepiped.

[0066] When attaching the first holding body 177, the first magnetic body 181 is fixed to the surface of the plate material 176 at a position offset from the first plane 174 (photo PC). The first magnets 182 that exert a magnetic force acting on the first magnetic body 181 are fixed to the back surface of the first holding body 177. The first magnets 182 are embedded in the back surface of the first holding body 177. When the first holding body 177 is received on the surface of the plate material 176, the first magnetic body 181 comes into surface contact with the first magnet 182. The first magnetic body 181 may have an outline that overlaps with the first magnet 182 when the first holding body 177 is overlapped on the plate material 176. The first holding body 177 is fixed to the plate material 176 by the action of the magnetic force. The photo PC is sandwiched between the overlapping plate material 176 and the first holding body 177. The first magnetic body 181 and the first magnet 182 may be formed of a transparent material. The first magnetic body 181 may be embedded in the surface of the plate material 176 .

[0067] The second holder 178 is placed on the back surface of the plate 176 and holds the piece of paper 108 between the plate 176 and the second holder 178. The piece of paper 108 is placed inside the outline of the photo PC projected on the back surface of the plate 176 in a direction perpendicular to the front surface of the plate 176. The second holder 178 can be made of a transparent body as a whole, for example. The transparent body can be molded from a hard acrylic resin, for example. The second holder 178 is formed from a material that blocks ventilation (non-breathable material). Here, the outline of the second holder 178 is placed on the outline of the first holder 177 and the plate 176. Therefore, the first holder 177, the plate 176, and the second holder 178 can be recognized as a single rectangular parallelepiped. Alternatively, the second holder 178 may be formed from an opaque material.

[0068] When the second holder 178 is attached, a second magnet 183 is fixed to the back surface of the plate material 176. The second magnet 183 is disposed inside the outline of the first magnetic body 181 projected in a direction perpendicular to the front surface of the plate material 176. A second magnetic body 184 is fixed to the front surface of the second holder 178, and is coupled to the corresponding second magnet 183 based on the magnetic force acting from the second magnet 183. The second magnet 183 is embedded in the back surface of the plate material 176. When the second holder 178 is received on the back surface of the plate material 176, the second magnetic body 184 comes into surface contact with the second magnet 183. The second magnetic body 184 may have an outline that overlaps with the second magnet 183 when the second holder 178 is placed on the plate material 176. The second holder 178 is fixed to the plate material 176 by the action of the magnetic force. The piece of paper 108 is sandwiched between the overlapping plate material 176 and second holding body 178. The second magnetic body 184 and the second magnet 183 may be made of a transparent material. A gap is formed between the rear surface of the plate material 176 and the front surface of the second holding body 178 based on the thickness of the piece of paper 108 and the thickness of the second magnetic body 184. As long as the gap is secured, the second magnetic body 184 may be embedded in the front surface of the second holding body 178.

[0069] A third magnet 185 is fixed to the back surface of the second holder 178. The third magnet 185 is disposed inside the outline of the second magnetic body 184 projected in a direction perpendicular to the front surface of the second holder 178. The third magnet 185 is embedded in the back surface of the second holder 178. When the photo frame 173 is received on the flat plate 105 of the auxiliary member 104, the third magnet 185 comes into surface contact with the front surface of the flat plate 105. The photo frame 173 is held on the flat plate 105 by the action of magnetic force. Here, the second holder 178 can be configured in the same way as the plate material 176. If the plate material 176 and the second holder 178 are made common, the manufacturing cost can be reduced.

[0070] Next, the operation of the photo frame 173 according to the third embodiment will be described. The photo frame 173 can be connected to the auxiliary member 104 of the photo stand 101 instead of the above-mentioned photo frame 103. The photo stand 101 is installed on a horizontal surface PL of a desk, a shelf, or other furniture. The leg plate 106 of the auxiliary member 104 is placed on the horizontal surface PL. The flat plate 105 is placed in an upright position on the horizontal surface PL. The photo frame 173 is fixed to the flat plate 105. The magnet 185 connects the photo frame 173 to the flat plate 105. The image of the photo PC is displayed forward through the first holder 177. The viewer can enjoy viewing the image. Since the photo frame 173 is connected to the auxiliary member 104 by magnetic force, the photo frame 173 can be easily removed from the auxiliary member 104.

[0071] The aroma components dissipate from the piece of paper 108. The aroma components pass through the gap between the plate material 176 and the second holder 178 and diffuse into the atmosphere from the periphery of the photo frame 173. The observer can enjoy the aroma while viewing the image. Visual sensitivity can be enhanced by olfactory sensitivity. When past visual information is linked to the aroma in the observer's memory, the observer can be immersed in a revived sense of presence.

[0072] When replacing the photo PC, the photo frame 173 is removed from the auxiliary member 104. In the photo frame 173, the first holder 177 is removed from the plate material 176. Since the first holder 177 is coupled to the plate material 176 by the magnetic force of the first magnet 182, the first holder 177 can be easily removed from the plate material 176. The photo PC is removed from the first flat surface 174. The photo PC can be pulled away from the plate material 176 as a single unit.

[0073] A new photograph PC is placed on the first flat surface 174 of the plate material 176. The image on the photograph PC is aligned. A first holder 177 is attached to the plate material 176. The first holder 177 is placed on the surface of the plate material 176. The first holder 177 covers the photograph PC. The first holder 177 is fixed to the plate material 176 in response to the magnetic force of the first magnet 182. In this way, the photograph PC can be replaced.

[0074] A user of the photo stand 101 can replenish the piece of paper 108 with the fragrance component. To replenish the fragrance component, the photo frame 173 is removed from the auxiliary member 104. In the photo frame 173, the second holder 178 is removed from the plate material 176. Since the second holder 178 is connected to the plate material 176 by the magnetic force of the second magnet 183, the second holder 178 can be easily removed from the plate material 176. The piece of paper 108 is removed from the second plane 175. The piece of paper 108 can be pulled away from the plate material 176 by itself. To replenish the fragrance component, the user may soak the piece of paper 108 in a liquid containing the fragrance component, or may spray the liquid containing the fragrance component (e.g., perfume) onto the piece of paper 108.

[0075] The piece of paper 108 is placed on the second flat surface 175 of the plate 176. The piece of paper 108 is aligned. The second holder 178 is attached to the plate 176. The second holder 178 is placed on the back surface of the plate 176. The second holder 178 covers the piece of paper 108. The second holder 178 is fixed to the plate 176 in response to the magnetic force of the second magnet 183. In this way, the fragrance component can be replenished to the piece of paper 108. Even if the fragrance disappears once, the user can enjoy the fragrance again by refilling. Even if the fragrance weakens, it can be strengthened by refilling.

[0076] When the second holder 178 is removed from the plate 176, the piece of paper 108 can be pulled off from the plate 176 alone. Since the piece of paper 108 is itself an absorbent for the fragrance, the fragrance only needs to soak into the piece of paper 108. For example, the fragrance can be sprayed onto the piece of paper, like perfume. The fragrance can be replenished in a short time and without hassle. Furthermore, the fragrance can be easily switched to another fragrance by replacing the piece of paper 108 alone. A different fragrance, like perfume, can be sprayed onto a new piece of paper 108.

[0077] The plate material 176 of this embodiment defines a first plane 174 on the front surface and a second plane 175 on the rear surface. The first holder 177 is placed on the front surface of the plate material 176 and holds the photograph PC between the plate material 176. The second holder 178 is placed on the rear surface of the plate material 176 and holds the piece of paper 108 between the plate material 176. The photograph PC and the piece of paper 108 are physically separated by the plate material 176. Contact between the photograph PC and the piece of paper 108 can be effectively avoided. The permeation of the aroma components from the piece of paper 108 into the photograph PC can be prevented. Moreover, the photograph PC can be kept away from the path of the vaporized aroma components. The transfer of the aroma components from the piece of paper 108 to the photograph PC can also be effectively prevented.

[0078] In this embodiment, the piece of paper 108 is disposed inside the outline of the photo PC projected onto the rear surface of the plate material 176 in a direction perpendicular to the front surface of the plate material 176. Since the piece of paper 108 is disposed behind the photo PC, the piece of paper 108 can be hidden by the photo PC from the front side even if the first holder 177 and the plate material 176 are both formed from a single transparent material. The image of the photo PC can be well highlighted.

[0079] FIG. 12 is a schematic diagram of a product packaging unit according to an embodiment of the present invention. The product packaging unit 191 includes an outer box 192. The outer box 192 is formed of a lower outer box 193 and an upper outer box 194 that covers the lower outer box 193 from above. As shown in FIG. 13, the lower outer box 193 is composed of a bottom plate 193a having a rectangular outline and four side plates 193b that rise vertically from the four sides of the bottom plate 193a. A rectangular storage space is defined inside the lower outer box 193. The inner box (product packaging box) 11 is stored in the storage space. The bottom plate 193a and the side plates 193b are individually formed of flat paper boards. The bottom plate 193a and the side plates 193b, as well as the side plates 193b, are connected to each other by ridges. The lower outer box 193 has a seamless, continuous appearance by the ridges.

[0080] The upper outer box 194 is composed of a top plate 194a having a rectangular outline and four side plates 194b that descend vertically from the four sides of the top plate 194a. The top plate 194a is supported by the upper end of the side plate 193b of the lower outer box 193 and closes the opening 195 of the lower outer box 193 that is surrounded by the side plate 193b. The side plate 194b of the upper outer box 194 surrounds the side plate 193b of the lower outer box 193. The top plate 194a and the side plate 194b are individually formed of flat paper board. The top plate 194a and the side plate 194b, as well as the side plates 194b themselves, are connected to each other by ridges. For example, a logo of the distributor or manufacturer can be printed on the top surface of the upper outer box 194. The upper outer box 194 has a seamless, continuous appearance at the ridges. The upper outer box 194 is entirely opaque. Alternatively, the top plate 194a may be made of a transparent resin material.

[0081] As shown in Fig. 14, the inner box 11 includes a lower box body 12 and an upper box body 13 that overlaps the lower box body 12 to form a rectangular parallelepiped together with the lower box body 12. The lower box body 12 includes a hard resin molded body having a bottom plate 14a with a rectangular outline and four side walls 14b that rise vertically from the four sides of the bottom plate 14a, and a sticker 15 that is attached to the outer surface of the resin molded body to decorate the resin molded body. The upper box body 13 includes a hard resin molded body having a top plate 16a that receives a photo frame 103 in a recess 61 with a rectangular outline, and side walls 16b that descend from the four sides of the top plate 16a and join at their lower ends to 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 attached to the outer surface of the resin molded body to decorate the resin molded body. The stickers 15 and 17 may be made of, for example, a suede-like or cloth-patterned resin sheet. Sticker 17 covers the inner surface of recess 61. The inner surface of recess 61 is neatly arranged with sticker 17. Upper box body 13 is formed of a material that blocks ventilation (non-breathable material) at least in the range that separates recess 61.

[0082] The photo frame 103 is fixed in the recess 61 by being fitted to the contour of the recess 61. The plate material 111 is fitted into the recess 61. When fitting, the plate material 111 comes into contact with the inner wall surface of the recess 61, for example, at the upper and lower edges in a plan view. The upper and lower edges (or either one) in a plan view position the plate material 111 in the up-down direction in a plan view. The surface of the plate material 111 defines a flat surface 63. The space above the flat surface 63 is surrounded by an enclosure 64. The enclosure 64 has a wall surface 64a that rises from a horizontal plane including the flat surface 63 in accordance with the contour of the recess 61. The wall surface 64a is continuous with the inner wall surface of the recess 61 within one vertical plane for each side of the contour. The wall surface 64a can guide the descent of the plate material 111 in the vertical direction. In this way, the plate material 111 and the enclosure 64 cooperate to form a tray on the upper surface of the upper box body 13. Plate material 111 constitutes the entire bottom plate of the tray. Here, recess 61 defines space 65 that is adjacent to the outer periphery of plate material 111 and opens in a horizontal plane including flat surface 63. Space 65 is located outside the left and right edges in a plan view. Space 65 may be located on either the left or right edge. Space 65 opens with a dimension that prevents small items from falling when used as a tray.

[0083] As shown in Fig. 15, cushioning material 18 is fitted into a rectangular parallelepiped space surrounded by side wall 14b of lower box body 12. Cushioning material 18 is formed, for example, from sponge and cloth material 18a that encases the sponge. Cushioning material 18 has a slit 19 formed therein. For example, a ring (jewelry) 21 is inserted into slit 19. Ring 21 is held in slit 19 by the elastic force of cushioning material 18.

[0084] The ring 21 includes a platinum ring member 22 having a diameter corresponding to the thickness of the finger, and a diamond grain 23 fixed to the base of the ring member 22. The diamond grain 23 may be one or more. The diamond grain 23 has strong or higher blue fluorescence (strong blue or very strong blue). The diamond grain 23 shines transparently under visible light (e.g., natural light or electric light), while shining blue under ultraviolet light. The diamond grain 23 is supported by the lower box body 12 in this manner. When multiple diamond grains 23 are arranged, it is preferable that the blue fluorescence of all the diamond grains 23 (or each group that is cohesive in design) is unified to strong blue or very strong blue.

[0085] A lining material 24 is fitted into the rectangular parallelepiped space surrounded by the side walls 16b of the upper box body 13. The lining material 24 comprises a decorative top plate 24a with a rectangular outline that forms the ceiling surface of the inner box 11, and four lining plates 24b that are continuous with each of the four sides of the decorative top plate 24a and are layered from the inside on the four side walls 16b. Here, the four lining plates 24b are not bonded to the inner surfaces of the side walls 16b, and the lining material 24 is housed in the upper box body 13 in a detachable manner.

[0086] As shown in Fig. 16, the upper box body 13 is connected to the lower box body 12 by a hinge 26 so as to be freely opened and closed. The hinge 26 includes a first blade 27 having a plurality of tubes 27a, which is stacked and fixed to one side wall 16b of the upper box body 13 from the inside, a second blade 28 having a plurality of tubes 28a arranged alternately in series on the tube 27a of the first blade 27, and one hinge pin 29 commonly inserted into the tube 27a of the first blade 27 and the tube 28a of the second blade 28. The first blade 27 and the second blade 28 rotate relatively around the hinge pin 29. The central axis of the hinge pin 29 corresponds to the rotation axis of the upper box body 13 when opening and closing.

[0087] A leaf spring 31 is connected to the hinge 26. As shown in FIG. 17, the leaf spring 31 is formed as a curved body that maintains a generatrix parallel to the axis of the hinge pin 29. Both ends of the leaf spring 31 are respectively connected to the first and second wings 27 and 28 at positions away from the hinge pin 29. In the closed position where the lower end of the upper box body 13 is aligned with the upper end of the lower box body 12, the first and second wings 27 and 28 are arranged side by side along one plane, and the middle region of the leaf spring 31 is furthest inward from the hinge pin 29. As the upper box body 13 is displaced around the hinge pin 29 from the closed position to the open position, the outer angle between the first and second wings 27 and 28 narrows, and the middle region of the leaf spring 31 approaches the hinge pin 29. 18, when the intermediate region of the leaf spring 31 contacts the hinge pin 29, the displacement of the upper box body 13 around the hinge pin 29 relative to the lower box body 12 is restricted, and the open position of the upper box body 13 is determined. When the opening angle around the hinge pin 29 is smaller than a specified intermediate opening angle, the leaf spring 31 applies a driving force to the upper box body 13 toward the closed position. When the opening angle is larger than the specified intermediate opening angle, the leaf spring 31 applies a driving force to the upper box body 13 toward the open position. The hinge 26 and the leaf spring 31 are covered with a hinge cover 32. The hinge cover 32 is formed, for example, from a material similar to the fabric material 18a of the cushioning material 18.

[0088] An LED lamp (light source) 33 that emits ultraviolet light in accordance with a predetermined directivity Dv is embedded in the decorative top plate 24a of the upper box body 13. The LED lamp 33 emits light rays, for example, long wavelength UV-A (optimally wavelength 395 nm to 405 nm). Desirably, the LED lamp 33 emits only light rays other than visible light. Desirably, the LED lamp 33 has a narrow directivity Dv. The LED lamp 33 has a directivity Dv that is blocked by the lower box body 12 over the entire irradiation area.

[0089] A battery 35 is connected to the LED lamp 33. The battery 35 is housed in a battery chamber 34 defined between the resin-molded top plate 16a and the decorative top plate 24a. The battery 35 may be, for example, a thin button battery. Here, for example, a plurality of button batteries are connected in series. A current is supplied to the LED lamp 33 from the battery 35.

[0090] A switch 36 that controls the supply and cut-off of current to the LED lamp 33 is incorporated in the hinge 26 and the leaf spring 31. A first contact 37 is fixed to the middle region of the leaf spring 31 while being electrically insulated from the leaf spring 31. The hinge 26 functions as a second contact that cooperates with the first contact 37 to configure the switch 36. Therefore, the hinge 26 is made of a conductive material. The first contact 37 is made of a conductive material such as copper. For example, an insulator is sandwiched between the first contact 37 and the leaf spring 31. The first contact 37 is disposed on a surface of the leaf spring 31 that faces the hinge pin 29. The first contact 37 comes into contact with the hinge 26 when the upper box body 13 is in the open position, and is separated from the hinge 26 when the upper box body 13 is in a position other than the open position.

[0091] A magnetic body 66 can be incorporated into the upper box body 13 to fix the photo frame 103. The magnetic body 66 is formed, for example, of a thin plate that forms the bottom surface of the recess 61. The thin plate may be, for example, a stainless steel plate. The magnet 124 of the photo frame 103 is in surface contact with the surface of the magnetic body 66. The magnetic force of the magnet 124 bonds the photo frame 103 to the magnetic body 66. The magnet 124 acts to fix the photo frame 103 in the recess 61. The photo frame 103 can be held well within the recess 61 regardless of whether the upper box body 13 is open or closed.

[0092] As shown in FIG. 19, a light irradiation circuit 38 according to a first specific example including an LED lamp 33, a battery 35, and a switch 36 is constructed in the inner box 11. In the light irradiation circuit 38, the LED element of the LED lamp 33 is connected in series to the battery 35. A timer-limited normally open contact (hereinafter, "timer contact") 39 is connected in series to the LED lamp 33. A switch 36 and a timer 41 are connected in parallel to the LED lamp 33 and the timer contact 39. When the switch 36 is conductive, the timer 41 operates, and the timer contact 39 closes after a predetermined time (hereinafter, "first time") has elapsed. As a result, the LED lamp 33 is energized. When the switch 36 is opened, the timer 41 is restored and the timer contact 39 is opened. As a result, the LED lamp 33 is turned off.

[0093] As shown in Fig. 20, an audio playback unit 45 that plays back recorded audio is built into the inner box 11. The audio playback unit 45 includes an audio circuit 48 that receives an audio signal from a microphone 46 and supplies the audio signal to a speaker 47. The audio circuit 48 is connected to a battery 35. The audio circuit 48 operates by receiving the voltage from the battery 35.

[0094] The microphone 46 detects vibrations in the air based on sound and converts them into an audio signal (electrical signal). The generated audio signal is recorded, for example, in a memory 49. For example, an EEPROM can be used for the memory 49. The memory 49 is preferably a memory that allows an audio signal to be written only once. The microphone 46 is supported by the upper box 13 or the lower box 12. Here, for example, the microphone 46 is housed in a space partitioned between the top plate 16a and the decorative top plate 24a. The top plate 16a or the decorative top plate 24a may have a through hole formed therein, which is disposed in correspondence with the position of the microphone 46 and connects outside air to the microphone 46.

[0095] The speaker 47 generates vibrations in the air based on an audio signal and reproduces the corresponding sound. The reproduced sound stimulates the observer's hearing. In this way, the observer can hear the sound. The speaker 47 is supported by the upper box body 13 or the lower box body 12. Here, the speaker 47 is housed in a space partitioned between the tabletop 16a and the decorative tabletop 24a, for example. The tabletop 16a or the decorative tabletop 24a may have a through hole disposed in correspondence with the position of the speaker 47 and connecting the outside air to the speaker 47.

[0096] A hold circuit 51 is connected to the audio playback unit 45, which holds audio playback until a predetermined time (hereinafter referred to as the "second time") has elapsed since the start of ultraviolet irradiation. The hold circuit 51 connects the switch 36 to the audio circuit 48. The battery 35 and switch 36 are common to the audio circuit 48 and the light irradiation circuit 38. The hold circuit 51 measures (first time + second time) from the time the switch 36 becomes conductive. Here, when the predetermined second time has elapsed since the start of ultraviolet irradiation, the audio circuit 48 retrieves an audio signal from the memory 49 and supplies it to the speaker 47.

[0097] A recording switch 52 is connected to the audio circuit 48. When the recording switch 52 is conductive, the audio circuit 48 acquires an audio signal from the microphone 46 and stores the audio signal in the memory 49. As shown in FIG. 21, the button of the recording switch 52 can be installed on the inner wall surface of the upper box 13. Here, the recording switch 52 is conductive as long as the button is kept pressed. When the button is released from the pressing operation, the recording switch 52 is disconnected. By arranging the button inside the upper box 13, the recording switch 52 can be protected from erroneous operation simply by the upper box 13 being in the closed position. The upper box 13 functions as a protective body that protects the recording switch 52 from objects other than the components of the inner box 11. In this way, unintentional recording of audio (deletion of audio based on overwriting) can be prevented. In addition, the recording switch 52 may be linked to the conduction of the switch 36. As a result, when the recording switch 52 is operated with the upper box 13 reaching the open position, audio can be recorded in the memory 49.

[0098] The LED lamp 33, timer contact 39, timer 41, audio circuit 48, memory 49 and hold circuit 51 may be mounted on a common printed circuit board, for example. The first contact 37 of switch 36, the first blade 27 or second blade 28 of hinge 26, battery 35, microphone 46, speaker 47, etc. may be electrically connected to a wiring pattern on the printed circuit board by electric wires such as vinyl-coated wires. The printed circuit board may be housed in the battery chamber 34, for example.

[0099] Next, the function of the inner box 11 will be described. As shown in Fig. 14, when the upper box body 13 is located in the closed position, the lower edge of the upper box body 13 is aligned with the upper edge of the lower box body 12. The upper box body 13 covers the ring 21 and hides the diamond grains 23. An observer of the inner box 11 visually recognizes the outer appearance of the closed inner box 11. The diamond grains 23 are out of the view of the observer.

[0100] At this time, as shown in Fig. 17, the intermediate region of the leaf spring 31 is farthest from the hinge pin 29. Therefore, the first contact 37 of the switch 36 is separated from the hinge 26, i.e., the second contact. The switch 36 is disconnected. The LED lamp 33 is maintained in an off state. The operation of the audio circuit 48 is maintained in a stopped state.

[0101] When an observer moves the upper box body 13 around the hinge pin 29 toward the open position against the elastic force of the leaf spring 31, the lower end of the upper box body 13 moves away from the upper end of the lower box body 12. Visible light penetrates through the gap between the upper box body 13 and the lower box body 12 toward the diamond grains 23. The diamond grains 23 are gradually exposed. The diamond grains 23 are exposed to irradiation with visible light. Therefore, the diamond grains 23 emit a transparent shine.

[0102] When the opening angle of the upper box body 13 increases beyond the specified intermediate opening angle, the leaf spring 31 drives the upper box body 13 toward the open position. As a result, the upper box body 13 reaches the maximum opening position. The upper box body 13 is held in the maximum opening position according to the elastic force of the leaf spring 31. The flat surface 63 of the upper box body 13 is positioned higher as it moves away from the axis of rotation. As shown in FIG. 15, the observer can see the diamond grains 23 without being obstructed by the upper box body 13. The diamond grains 23 emit a transparent glow under visible light (natural light or electric light).

[0103] When the upper box body 13 reaches the open position, as shown in Fig. 18, the elastic force of the leaf spring 31 presses the middle region of the leaf spring 31 against the hinge pin 29. Thus, the first contact 37 comes into contact with the hinge 26, i.e., the second contact. The switch 36 becomes conductive. When the first time has elapsed since the switch 36 became conductive (ON operation), the LED lamp 33 turns on. The LED lamp 33 starts irradiating the diamond grains 23 with ultraviolet light. The diamond grains 23 glow blue.

[0104] After the diamond grains 23 are observed shining transparently for a while after the upper box body 13 is opened, the diamond grains 23 change color from transparent to blue. In this way, a light dramatic effect is created in response to the opening action of the upper box body 13. Since the leaf spring 31 exerts a driving force to position the upper box body 13 at the open position, the diamond grains 23 are prevented from starting to change color at a position intermediate between the closed position and the open position, and the observer can reliably witness the change in color of the diamond grains 23.

[0105] When the second time has elapsed since the start of the ultraviolet irradiation, the audio circuit 48 reproduces the recorded audio. For example, if it is a present, the giver's voice (for example, "Marry me" or "Let's be together from now on") can be delivered to the observer. Since the reproduction of the audio is delayed from the visual effect of the diamond grains 23, the visual effect of the diamond grains 23 and the audio production effect act on the observer in sequence. The observer can become aware of the auditory effect of the audio (including language processing) after becoming aware of the visual effect of the diamond grains 23. The audio production effect is added to the visual effect. According to the inventor's realization, since humans cannot be aware of multiple senses at the same time, the synergistic effect of the visual and audio can be strengthened by delaying the reproduction of the audio from the visual effect, compared to when the audio production effect progresses simultaneously with the visual effect. With this production effect, the observer of the inner box 11 can experience an emotion that cannot be experienced anywhere else.

[0106] When the switch 36 is disconnected, the LED lamp 33 goes out. The audio circuit 48 stops supplying the audio signal. The audio playback ends.

[0107] Prior to giving the gift, the giver's voice is recorded in the inner box 11. To record, the upper box body 13 is positioned in the open position. The giver presses the recording switch 52 and speaks into the microphone 46 (for example, "Will you marry me?" or "Let's be together from now on"). The audio circuit 48 operates in response to the conduction of the recording switch 52. The voice is converted into an audio signal by the microphone 46. The audio signal is stored in the memory 49. When the finger is released from the button of the recording switch 52, the voice recording ends.

[0108] Here, it is preferable that the fabric material 18a of the cushioning material 18 is colored in a color such as black or dark blue. With such coloring, even if the light from the LED lamp 33 slightly contains visible light adjacent to the ultraviolet range, the visible light shining on the fabric material 18a is not noticeable. The light from the LED lamp 33 can be excluded from the viewer's vision.

[0109] For example, consider a scene in which a man and a woman visit a jewelry shop to purchase jewelry. The interior of the jewelry shop is filled with a scent specific to the jewelry shop and the brand. Here, the piece of paper 108 of the photo frame 103 can contain an aromatic component that gives the impression of the scent of the store. In this way, the scent of the interior of the jewelry shop is associated with the inner box 11. When the ring 21 is purchased at the jewelry shop, the purchase scene can be linked to the scent. The scent is strongly remembered by the man and the woman.

[0110] When the inner box 11 is taken out of the outer box 192, the scent of the jewelry shop wafts around the inner box 11. As shown in FIG. 22, the fragrant components of the piece of paper 108 leak out from the through-hole 125 into the space 65. The leaked fragrant components are dispersed from the space 65 toward the upper part of the upper box body 13. The woman can enjoy the scent every time she takes out the inner box 11. If the woman received the ring 21 as a gift, she will remember the joy she felt when receiving the gift every time she approaches the inner box 11 at home. The inner box 11 can create an opportunity to remember the joy she felt when receiving the gift. The man's impression can be strongly planted on the woman.

[0111] The inner box 11 can be displayed in the room as a source of fragrance emission. The woman can see the inner box 11 frequently in the room. In this way, the woman can frequently remember the joy of receiving the present. The impression of the man can be strongly imprinted on the woman.

[0112] The enclosure 64 functions to form a tray on the top surface of the upper box 13. Small items such as the ring 21 and key holders can be placed on the plate material 111. The enclosure 64 functions to hold the small items on the plate material 111. Since such a tray is used daily, the woman can see the inner box 11 frequently. The emotions felt when receiving the gift can be strongly imprinted in the woman's memory. The impression of the ring 21, the brand, and the jewelry store at the time of purchase can be strongly imprinted on the observer of the inner box 11.

[0113] The plate 111 is fixed to the magnetic body 66 by the magnetic force of the magnet 124. Access to the outer periphery of the plate 111 can be permitted from the space 65. The plate 111 can be easily pulled up from the recess 61 by applying an external force to the outer periphery of the plate 111. The photo frame 103 can be easily removed from the upper box 13. As described above, the piece of paper 108 can be taken out of the photo frame 103, so that the piece of paper 108 can be replenished with the fragrant components. Alternatively, the piece of paper 108 may be replaced with one that contains a sufficient amount of fragrant components. In this way, the woman can enjoy the fragrance from the inner box 11 forever. The space 65 can be formed to be thin and extend along the left and right edges of the plate 111, and to be large enough to receive, for example, the insertion of a ring 21. In this case, a hard tool can be inserted into the space 65 to remove the photo frame 103.

[0114] For example, at a jewelry shop, the scene of the purchase can be captured by an instant camera. The scene of the purchase can be developed on the spot onto an instant film (photo PC). The plate 111 serves to hold the instant film within the recess 61. In this way, the photo PC can be easily attached to the inner box 11. The viewer can enjoy the image on the instant film by looking through the transparent plate 102. The image can further enhance the emotion of receiving the gift.

[0115] The inner box 11 according to this embodiment causes the diamond grains 23 to change color from transparent to fluorescent blue. The owner of the ring 21 uses the inner box 11 to enjoy the color change of the diamond grains 23. In this way, the inner box 11 continues to be owned together with the ring 21. The opportunities for the inner box 11 to be taken out increase. The opportunities for seeing images on the instant film increase. With general products, the packaging box is often thrown away once the product begins to be used.

[0116] Similarly, the inner box 11 according to this embodiment plays back recorded sound. Since the sound production effect is realized in this way, the owner of the ring 21 keeps the inner box 11 instead of throwing it away, and enjoys the sound production effect. In this way, the inner box 11 continues to be owned together with the ring 21. The opportunities for the inner box 11 to be taken out further increase. The opportunities for viewing images on the instant film further increase.

[0117] In this embodiment, the plate material 111 of the photo frame 103 is formed into a rectangular outline. The plate material 111 can be held by being sandwiched between wall surfaces that face each other and extend in parallel within the recess 61. The photo frame 103 can not only function as a photo stand 101 when combined with the auxiliary member 104, but can also be attached to the inner box 11 of the product packaging unit 191 to add the enjoyment of viewing photos PCs in the product packaging unit 191. A photo frame 173 can be used in the inner box 11 of the product packaging unit 191 instead of the photo frame 103.

[0118] As shown in FIG. 23, when assembling the photo frame 103, the plate material 111 may be formed with a through hole 137 that extends from the paper piece chamber and opens to the surface of the plate material 111. The lower end of the through hole 137 overlaps the piece of paper 108 inside the outline of the piece of paper 108. The fragrant components of the piece of paper 108 can be diffused from the through hole 137 toward the top of the plate material 111. The scent wafts around the inner box 11. Here, the magnet 124 can be embedded in the back surface of the plate material 111. The back surface of the plate material 111 can be trimmed to be flush.

[0119] FIG. 24 shows a schematic configuration of a light irradiation circuit according to a second specific example. The light irradiation circuit 43 includes an NPN transistor TR1 connected to a battery 35. The LED element of the 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 irradiation circuit 43, when the switch 36 is turned on, the voltage applied to the base B of the NPN transistor TR1 gradually rises due to the action of the time constant circuits R1 and C1. When the voltage at the base B of the NPN transistor TR1 reaches a specified value during the voltage rise, a current flows into the collector C. After that, when a specified time has elapsed, the voltage applied to the base B of the NPN transistor TR1 is maintained constant. When the switch 36 is turned off, the charge in the capacitor C1 is discharged through the second resistor R2.

[0120] The hold circuit 51 of the sound reproduction unit 45 holds the sound reproduction until a predetermined time (hereinafter referred to as "third time") has elapsed after the ultraviolet light reaches the maximum light intensity. The battery 35 and the switch 36 are shared between the sound circuit 48 and the light irradiation circuit 43. The hold circuit 51 measures the time from when the switch 36 is turned on until the ultraviolet light reaches the maximum light intensity (hereinafter referred to as "gradual increase time"), and the third time. The gradual increase time can be specified by the voltage characteristics of the light irradiation circuit 43. The gradual increase time corresponds to the time from when the switch 36 is turned on until the voltage applied to the base B of the NPN transistor TR1 starts to be maintained at the maximum value. Here, when the predetermined third time has elapsed from the time when the ultraviolet light reaches the maximum light intensity, the sound circuit 48 retrieves the sound signal from the memory 49 and supplies it to the speaker 47.

[0121] The LED lamp 33, the NPN transistor TR1, the capacitor C1, the first and second resistors R1, R2, the audio circuit 48, the memory 49, and the hold circuit 51 may be mounted on a common printed circuit board, for example. The first contact 37 of the switch 36, the first blade 27 or the second blade 28 of the hinge 26, the battery 35, the microphone 46, the speaker 47, etc. may be electrically connected to a wiring pattern on the printed circuit board by electric wires such as vinyl-coated wires. The printed circuit board may be housed in the battery chamber 34, for example.

[0122] In the light irradiation circuit 43 according to the second specific example, after the upper box body 13 reaches the open position and the switch 36 is turned on, a specified voltage is applied from the battery 35 to the base B of the NPN transistor TR1 after a first time has elapsed since the switch 36 was turned on (ON operation). Current flows into the collector C of the NPN transistor TR1, and the LED lamp 33 starts to light up. Therefore, an observer of the inner box 11 can observe the diamond grains 23 that shine transparently for a while after the upper box body 13 is opened.

[0123] The voltage applied to the base B of the NPN transistor TR1 gradually rises due to the action of the time constant circuits R1 and C1. The amount of current flowing through the LED lamp 33 gradually increases. The amount of ultraviolet light irradiated from the LED lamp 33 to the diamond grains 23 increases. The diamond grains 23 gradually change color from transparent to blue. In this way, a light dramatic effect is created in response to the opening operation of the upper box body 13. The leaf spring 31 exerts a driving force to position the upper box body 13 in the open position, preventing the diamond grains 23 from starting to change color at a position intermediate between the closed position and the open position, and the observer can reliably witness the color change of the diamond grains 23.

[0124] When the second time has elapsed since the start of the irradiation of ultraviolet light, that is, when the third time has elapsed since the diamond grains 23 began to shine blue to the maximum, the audio circuit 48 plays back the recorded audio. For example, if it is a present, the giver's voice (for example, "Marry me" or "Let's be together from now on") can be delivered to the observer. Since the playback of the audio is delayed from the visual effect of the diamond grains 23, the visual effect of the diamond grains 23 and the audio production effect act on the observer in sequence. The observer can become aware of the auditory effect of the audio (including language processing) after becoming aware of the visual effect of the diamond grains 23. The audio production effect is added to the visual effect. According to the inventor's realization, since humans cannot be aware of multiple senses at the same time, the synergistic effect of the visual and audio can be strengthened by delaying the playback of the audio from the visual effect, compared to when the audio production effect progresses simultaneously with the visual effect. With this production effect, the observer of the inner box 11 can experience an emotion that cannot be experienced anywhere else.

[0125] When the switch 36 is disconnected, the LED lamp 33 goes out. The audio circuit 48 stops supplying the audio signal. The audio playback ends. The charge on the capacitor C1 is discharged through the second resistor R2.

[0126] The LED lamp 33 may be supported by the lower box 12 instead of the upper box 13. Alternatively, the diamond grains 23 may be mounted on a plurality of pedestals forming a necklace chain. The pedestals are formed from a metal material such as platinum or gold. One diamond grain 23 or a plurality of diamond grains 23 may be fixed to each pedestal. Alternatively, the diamond grains 23 may be arranged on a pendant, bracelet, earrings, ring, or anklet. The diamond grains may be of uniform size or may be mixed in size.

[0127] In the inner box 11 described above, the switch 36 may be a tactile switch having a plunger that is pushed down by the upper box body 13 when the upper box body 13 reaches the open position. The light irradiation circuit 38 according to the first specific example and the light irradiation circuit 43 according to the second specific example may be replaced with electronic circuits of other configurations as long as they realize the same functions as those described above. Furthermore, the operation of the switch 36 may not only be linked to the upper box body 13 being in the open position as described above, but may also be linked to the upper box body 13 being in the closed position. In addition, the functions of the light irradiation circuits 38 and 43, the sound circuit 48, and the hold circuit 51 may be realized by software executed by a microprocessor (MPU).
