  One embodiment will be described with reference to FIG. For convenience of explanation, this embodiment is referred to as a first embodiment.

  FIG. 1 is a schematic view of the magic mirror unit 101 as viewed in cross section. The magic mirror unit 101 has a plate-like part 201 and an illumination part 301.

  The plate-like portion 201 has a plate-like base material 202 having translucency. Although not shown, the base material 202 is formed in a rectangular shape when viewed from the right or left side of FIG. For the base material 202, a glass material such as soda glass, an acrylic resin, polycarbonate, polyvinyl chloride, or the like can be used. The substrate 202 may be colorless and transparent or colored and transparent. A metal thin film layer 203 is laminated on one surface (first surface 202 a) of the base material 202. The metal thin film layer 203 is a thin film layer provided so as to have a predetermined light transmittance (light reflectance) with a metal having high light reflectance such as aluminum or silver. The metal thin film layer 203 is formed on the first surface 202a of the substrate 202 by vapor deposition or coating.

  The base material 202 and the metal thin film layer 203 constitute a so-called magic mirror M. When the magic mirror M is arranged at a location that partitions the bright space and the dark space, a person who sees the magic mirror M from the bright space can see the image of the person reflected on the magic mirror M. A person who looks at the magic mirror M from a bright space can see a bright space through the magic mirror M.

  The illumination unit 301 is disposed on the upper part of the plate-like unit 201. The illumination unit 301 includes an illumination body 302, a housing 303, and a control circuit (not shown). As the illumination body 302, LED illumination (light emitting diode), more preferably, straight tube fluorescent lamp type LED illumination is used. Various light sources other than LED lighting can be used as the light source used for the illumination body 302. Further, the control circuit supplies power supplied from an external power source to the illuminating body 302 to turn on the illuminating body 302, or cuts off this power to turn off the illuminating body 302.

  The housing 303 has a mounting portion 304 and a protruding portion 305. The attachment part 304 is attached to the upper part of the plate-like part 201. The protruding portion 305 protrudes from the attachment portion 304 to the side of the base material 202 opposite to the metal thin film layer 203 (second surface 204). The illuminating body 302 is accommodated in the urging portion 305. The illuminator 302 illuminates the second surface 204 of the substrate 202.

  The magic mirror unit 101 is provided at a location that partitions the indoor space V1 and the outdoor space V2. At this time, the illuminating body 302 is disposed in the outdoor space V2.

  As a first case, consider a case where the indoor space V1 is darker than the outdoor space V2 (for example, during the daytime). In this case, a person in the indoor space V1 can visually recognize the outdoor space V2 through the plate-like portion 201 of the magic mirror unit 101. On the other hand, a person in the outdoor space V2 cannot visually recognize the indoor space V1 through the plate-like portion 201 of the magic mirror unit 101. That is, in the first case, securing the view scenery from the indoor space V1 and preventing peeping from the outdoor space V2 are realized without turning on the lighting body 302.

  As a second case, consider a case where the indoor space V1 is brighter than the outdoor space V2 (for example, at night). In this case, the illumination body 302 is turned on to brighten the second surface 204, so that the inside of the outdoor space V2 can be viewed from the indoor space V1 side, and the inside of the indoor space V1 cannot be viewed from the outdoor space V2 side. . That is, in the second case, by ensuring that the lighting body 302 is turned on, it is possible to secure a view landscape from the indoor space V1 and prevent peeping from the outdoor space V2.

  As described above, in the magic mirror unit 101 of the present embodiment, the illumination body 302 is turned on to brighten the second surface 204, and the plate-like portion 201 functions as the magic mirror M even at night.

  Furthermore, according to the magic mirror unit 101 of the present embodiment, the illumination unit 301 does not block the field of view when viewing the outdoor space V2 from the indoor space V1.

  Furthermore, LED illumination is employed in the magic mirror unit 101 of the present embodiment. For this reason, there is little power consumption and an electricity bill becomes very cheap. In addition, it has good durability and the maintenance labor is greatly reduced.

  Another embodiment will be described with reference to FIG. For convenience of explanation, this embodiment is referred to as a second embodiment. Here, the same reference numerals are given to the same parts as those of the first embodiment described above, and the description thereof is omitted. This embodiment is an application example in which the magic mirror unit of the first embodiment is used for a window structure.

  FIG. 2 is a schematic view of the window structure 401 as viewed from the outdoor space V2 side. The window structure 401 includes a wall portion 402 and a magic mirror unit 101 (see the first embodiment). The wall portion 402 is provided at a location partitioned into the indoor space V1 side (the back side in FIG. 2) and the outdoor space V2 side (the front side in FIG. 2). The wall 402 is provided with a rectangular hole H that communicates the indoor space V1 side and the outdoor space V2 side. A window frame portion 403 is provided on the wall portion 402 along the edge of the hole portion H. The magic mirror unit 101 is fitted into the window frame portion 403. At this time, the illumination unit 301 is disposed along the upper edge of the window frame unit 403. Further, the metal thin film layer 203 is directed to the indoor space V1 side. Accordingly, the protruding portion 305 of the housing 303 protrudes from the wall portion 402 toward the outdoor space V2 side.

  Thus, in the window structure 401 of the present embodiment, the illuminating body 302 is turned on to brighten the outdoor space V2 side (second surface 204), and the magic mirror M is placed on the plate-like portion 201 even at night. Function can be demonstrated. Accordingly, it is possible to secure a view scenery from the indoor space V1 and prevent peeping from the outdoor space V2 during both daytime and nighttime.

  Another embodiment will be described with reference to FIG. For convenience of explanation, this embodiment will be referred to as a third embodiment. Here, the same reference numerals are given to the same parts as those of the embodiments described so far, and the description thereof is omitted. The present embodiment is an application example in which the magic mirror unit of the first embodiment is used for a handrail (veranda handrail).

  FIG. 3 is a schematic view of the handrail 501 viewed from the outdoor space V2 side. The handrail 501 constitutes a veranda (not shown) protruding from a building such as a detached house or an apartment. The veranda has a floor portion 502 and a handrail 501 standing from the floor portion 502. Residents exiting the building entrance can stay on the floor 502. The handrail 501 prevents a resident staying on the floor 502 from falling from the veranda.

  The handrail 501 includes a wall portion 503 and a plurality of magic mirror units 101 (see the first embodiment). The wall portion 503 corresponds to the wall portion 402 in the second embodiment. The floor portion 502 extends horizontally from the wall portion 503 toward the indoor space V1 side (the back side of the paper surface in FIG. 3).

  The wall portion 503 is provided with a plurality of rectangular holes H that communicate the indoor space V1 side and the outdoor space V2 side in a horizontal direction. The magic mirror unit 101 is fitted into each hole H. At this time, similarly to the window structure 401 in the second embodiment, the illumination unit 301 is located above the plate-shaped unit 201 and is directed toward the metal thin film layer 203 indoor space V1 side. Protrudes from the wall 402 toward the outdoor space V2 side. Here, a window frame portion (see the first embodiment) may be provided between the wall portion 503 and the magic mirror unit 101.

  Thus, in the handrail 501 of the present embodiment, the illumination body 302 is turned on to brighten the outdoor space V2 side (second surface 204), and the magic mirror M is formed on the plate-like portion 201 even at night. The effect of can be demonstrated. Accordingly, it is possible to secure a view scenery from the indoor space V1 and prevent peeping from the outdoor space V2 during both daytime and nighttime.

  Another embodiment will be described with reference to FIG. For convenience of explanation, this embodiment will be referred to as a fourth embodiment. The present embodiment relates to a magic mirror unit. The same parts as those in the first embodiment described above are denoted by the same reference numerals, and description thereof is omitted.

  FIG. 4 is a schematic view of the magic mirror unit 101A as viewed in cross section. The magic mirror unit 101A of the present embodiment includes a plate-like portion 201 and an illumination portion 301A.

  The illumination unit 301A includes a light emitting unit 301Aa, a diffusion unit 301Ab, and a reflection unit 301Ac. The light emitting unit 301 </ b> Aa is disposed on the upper part of the plate-like unit 201. The diffusion unit 301Ab is disposed along the second surface 204. The reflective portion 301Ac is disposed below the plate-like portion 201.

  The light emitting unit 301Aa includes a lighting body 302, a housing 303A, and a control circuit (not shown). The housing 303 </ b> A is attached to the upper end surface of the plate-like portion 201 and houses the illumination body 302. The illuminating body 302 is disposed to face the upper end surface of the plate-like portion 201.

  The diffusing portion 301 </ b> Ab is a light-transmitting sheet and is attached to the second surface 204. In the diffusing portion 301Ab, the reflective particles 306 are included in a dispersed state. For example, silver particles are employed as the reflective particles 306. The light L that has passed through the substrate 202 through the upper end surface of the plate-like portion 201 from the illuminating body 302 and entered the 301 Ab is diffused by the reflective particles 306.

  The reflective portion 301Ac is attached to the lower end surface of the plate-like portion 201. For example, a plane mirror or a convex mirror is employed as the reflecting portion 301Ac. The reflective portion 301Ac deflects light L from the illuminating body 302 that has entered from the upper end surface of the plate-like portion 201 and passed through the base material 202 and reached the lower end surface of the base material 202 upward. The reflection portion 301Ac is directed in a direction that allows the incident light L to reach the diffusion portion 301Ab.

  When the magic mirror unit 101A of the present embodiment is used, the illuminator 302 is turned on when the indoor space V1 is brighter than the outdoor space V2 (for example, at night). The light L emitted from the illuminating body 302 is diffused and irradiated downward, and part of the light L directly enters the diffusion portion 301Ab and is diffused by the reflective particles 306. A part of the light is reflected by the magic mirror surface of the metal thin film layer 203 and enters the diffusion portion 301Ab to be diffused. Further, a part of the light is directly reflected by the reflecting portion 301Ac, enters the diffusing portion 301Ab, and is diffused.

  Thereby, the 2nd surface 204 becomes bright, and even at night, the plate-shaped part 201 can exhibit the function as the magic mirror M, and the indoor space V1 side cannot be visually recognized from the outdoor space V2 side. .

  In this embodiment, the diffusing portion 301Ab is a light-transmitting sheet, but the reflective particles 306 for diffusing light are dispersed on the second surface 204 side of the substrate 202. It may be one that has been fixed in place, or may be one in which a large number of fine protrusions are formed. The protrusions may be formed by surface treatment, vapor deposition, printing, or the like of the base material 202.

  Further, it may be a spot printed with a color that easily reflects light, such as a transparent color, white color, or silver color, by silk printing.

  In the silk printing, when a large number of spots are formed, the size of the spots in the portion far from the light source is preferably larger than that in the near portion, or the interval between the spots is narrowed. Furthermore, in order to enhance the diffusion effect, the shape of the spots to be printed may be an irregular shape such as a polygonal shape or a star shape in addition to a circular shape. Furthermore, in the ink to be used, an ink in which reflective particles are mixed in a transparent color may be used.

  In this embodiment, the metal thin film layer 203 is formed on the first surface 202a side of the base material 202 to form the magic mirror M. However, the film having the magic mirror function on the first surface 202a side of the base material 202 is used. Affixed with may also be used.

  As described above, according to the magic mirror unit 101A of the present embodiment, it is possible to secure the view scenery from the indoor space V1 and prevent the peep from the outdoor space V2 during both daytime and nighttime.

  Furthermore, according to the magic mirror unit 101A of the present embodiment, the housing 303A does not have the protruding portion 305 (see FIG. 1), and the field of view seen from the indoor space V1 through the plate-like portion 201 is further expanded. Further, there is no urging portion 305, and no dirt accumulates between the urging portion 305 and the plate-like portion 201. Furthermore, the situation where the ejection part 305 is damaged cannot occur.

  Furthermore, the magic mirror unit 101A of the present embodiment has a reflecting portion 301Ac. For this reason, the light L from the illuminating body 302 is guided to the diffusing portion 301Ab without waste, the second surface 204 side becomes brighter, and the peeping prevention from the outdoor space V2 is further ensured.

  Another embodiment will be described with reference to FIG. For convenience of explanation, this embodiment will be referred to as a fifth embodiment. The present embodiment relates to a magic mirror unit and is similar to the fourth embodiment. The same parts as those in the first embodiment or the fourth embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  FIG. 5 is a schematic view of the magic mirror unit 101B as viewed in cross section. In the magic mirror unit 101B of the present embodiment, a phosphorescent portion 301Bb is arranged along the second surface 204 instead of the diffusion portion 301Ab (see the fourth embodiment).

  The phosphorescent portion 301 </ b> Bb is a sheet-like member having translucency and is attached to the second surface 204. In the phosphorescent part 301Bb, particulate luminous material 307 is contained in a dispersed state. A commercially available phosphorescent pigment can be used for the phosphorescent material 307, and for example, a high-intensity long persistence phosphorescent pigment N Luminova (registered trademark) manufactured by Nemoto Special Chemical Co., Ltd. is preferable. Light L from the illuminating body 302 that has passed through the upper end surface of the plate-like portion 201 and passed through the base material 202 is incident on the phosphorescent material 307. Light L from the illuminating body 302 deflected by the reflecting surface 301Ac on the reflecting surface of the metal thin film layer 203 or the lower surface of the base material 202 is also incident on the phosphorescent material 307. Furthermore, not only the light L from the illumination body 302 but also light (for example, sunlight) from the indoor space V1 and the outdoor space V2 is incident on the phosphorescent material 307.

  When using the magic mirror unit 101B of the present embodiment, the illuminator 302 is turned on, and the light L from the illuminator 302 is directly or via the reflective surface 202a of the metal thin film layer 203 or the reflective portion 301Ac. The light is incident on the light storage unit 301Bb. And even if the indoor space V1 becomes brighter than the outdoor space V2, the 2nd surface 204 becomes bright by the light-accumulation part 301Bb which light-emitted. As a result, the second surface 204 becomes brighter, and even at night, the plate-like portion 201 functions as the magic mirror M so that the outdoor space V2 side can be visually recognized from the indoor space V1 side. Thus, the inside of the indoor space V1 can be made invisible from the outdoor space V2 side. Note that the illumination body 302 may be turned off or turned on at night.

  As described above, according to the magic mirror unit 101B of the present embodiment, it is possible to secure the view scenery from the indoor space V1 and prevent the peep from the outdoor space V2 during both daytime and nighttime.

  When light is sufficiently incident on the phosphorescent unit 301Bb due to receiving sunlight in the daytime, the magic mirror unit 101B does not have to be provided with the illumination unit 301A. In this case, a power source for lighting the illumination body 302 of the illumination unit 301A is not necessary.

  Further, the reflective particles 306 (see the fourth embodiment) may be mixed together with the phosphorescent material 307 in the sheet-like phosphorescent portion 301B, or the phosphorescent material 307 (this embodiment) is incorporated in the base material 202. (See the fifth embodiment) and the reflective particles 306 (see the fourth embodiment) may be mixed. In this case, at night, the phosphorescent material 307 emits light and the indoor space V1 cannot be seen from the outdoor space V2. Even when the phosphorescent material 307 cannot store enough light due to irregular weather during the daytime, the illuminating body 302 can be turned on so that the indoor space V1 cannot be seen from the outdoor space V2.

  Another embodiment will be described with reference to FIG. For convenience of explanation, this embodiment will be referred to as a sixth embodiment. This embodiment relates to a magic mirror unit and basically conforms to the first embodiment. The same parts as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

  FIG. 6 is a schematic view of the magic mirror unit 101C as viewed in cross section. The magic mirror unit 101C of the present embodiment includes a plate-like portion 201 and an illumination portion 301C.

  The illumination unit 301C includes an organic EL illumination plate 308 and a control circuit 309. The organic EL lighting plate 308 is attached to the second surface 204. The control circuit 309 controls the voltage applied to the organic EL lighting plate 308. The organic EL lighting plate 308 is allowed to transmit light when no voltage is applied, and the entire plate shines evenly when a voltage is applied.

  When the magic mirror unit 101C of the present embodiment is used, a voltage is applied to the organic EL lighting plate 308 using the control circuit 309 when the indoor space V1 is brighter than the outdoor space V2 (for example, at night). As a result, the entire organic EL lighting plate 308 shines, the second surface 204 becomes bright, and even at night, the plate-like portion 201 functions as the magic mirror M, so that the indoor space can be seen from the outdoor space V2 side. The V1 side can be made invisible.

  One embodiment will be described with reference to FIG. For convenience of explanation, this embodiment is referred to as a first embodiment.

  FIG. 1 is a schematic view of the magic mirror unit 101 as viewed in cross section. The magic mirror unit 101 has a plate-like part 201 and an illumination part 301.

  The plate-like portion 201 has a plate-like base material 202 having translucency. Although not shown, the base material 202 is formed in a rectangular shape when viewed from the right or left side of FIG. For the base material 202, a glass material such as soda glass, an acrylic resin, polycarbonate, polyvinyl chloride, or the like can be used. The substrate 202 may be colorless and transparent or colored and transparent. A metal thin film layer 203 is laminated on one surface (first surface 202 a) of the base material 202. The metal thin film layer 203 is a thin film layer provided so as to have a predetermined light transmittance (light reflectance) with a metal having high light reflectance such as aluminum or silver. The metal thin film layer 203 is formed on the first surface 202a of the substrate 202 by vapor deposition or coating.

  The base material 202 and the metal thin film layer 203 constitute a so-called magic mirror M. When the magic mirror M is arranged at a location that partitions the bright space and the dark space, a person who sees the magic mirror M from the bright space can see the image of the person reflected on the magic mirror M. A person who looks at the magic mirror M from a bright space can see a bright space through the magic mirror M.

  The illumination unit 301 is disposed on the upper part of the plate-like unit 201. The illumination unit 301 includes an illumination body 302, a housing 303, and a control circuit (not shown). As the illumination body 302, LED illumination (light emitting diode), more preferably, straight tube fluorescent lamp type LED illumination is used. Various light sources other than LED lighting can be used as the light source used for the illumination body 302. Further, the control circuit supplies power supplied from an external power source to the illuminating body 302 to turn on the illuminating body 302, or cuts off this power to turn off the illuminating body 302.

  The housing 303 has a mounting portion 304 and a protruding portion 305. The attachment part 304 is attached to the upper part of the plate-like part 201. The protruding portion 305 protrudes from the attachment portion 304 to the side of the base material 202 opposite to the metal thin film layer 203 (second surface 204). The illuminating body 302 is accommodated in the urging portion 305. The illuminator 302 illuminates the second surface 204 of the substrate 202.

  The magic mirror unit 101 is provided at a location that partitions the indoor space V1 and the outdoor space V2. At this time, the illuminating body 302 is disposed in the outdoor space V2.

  As a first case, consider a case where the indoor space V1 is darker than the outdoor space V2 (for example, during the daytime). In this case, a person in the indoor space V1 can visually recognize the outdoor space V2 through the plate-like portion 201 of the magic mirror unit 101. On the other hand, a person in the outdoor space V2 cannot visually recognize the indoor space V1 through the plate-like portion 201 of the magic mirror unit 101. That is, in the first case, securing the view scenery from the indoor space V1 and preventing peeping from the outdoor space V2 are realized without turning on the lighting body 302.

  As a second case, consider a case where the indoor space V1 is brighter than the outdoor space V2 (for example, at night). In this case, the illumination body 302 is turned on to brighten the second surface 204, so that the inside of the outdoor space V2 can be viewed from the indoor space V1 side, and the inside of the indoor space V1 cannot be viewed from the outdoor space V2 side. . That is, in the second case, by ensuring that the lighting body 302 is turned on, it is possible to secure a view landscape from the indoor space V1 and prevent peeping from the outdoor space V2.

  As described above, in the magic mirror unit 101 of the present embodiment, the illumination body 302 is turned on to brighten the second surface 204, and the plate-like portion 201 functions as the magic mirror M even at night. Can be made. Accordingly, it is possible to secure a view scenery from the indoor space V1 and prevent peeping from the outdoor space V2 during both daytime and nighttime.

  Furthermore, according to the magic mirror unit 101 of the present embodiment, the illumination unit 301 does not block the field of view when viewing the outdoor space V2 from the indoor space V1.

  Furthermore, LED illumination is employed in the magic mirror unit 101 of the present embodiment. For this reason, there is little power consumption and an electricity bill becomes very cheap. In addition, it has good durability and the maintenance labor is greatly reduced.

  Another embodiment will be described with reference to FIG. For convenience of explanation, this embodiment is referred to as a second embodiment. Here, the same reference numerals are given to the same parts as those of the first embodiment described above, and the description thereof is omitted. This embodiment is an application example in which the magic mirror unit of the first embodiment is used for a window structure.

  FIG. 2 is a schematic view of the window structure 401 as viewed from the outdoor space V2 side. The window structure 401 includes a wall portion 402 and a magic mirror unit 101 (see the first embodiment). The wall portion 402 is provided at a location partitioned into the indoor space V1 side (the back side in FIG. 2) and the outdoor space V2 side (the front side in FIG. 2). The wall 402 is provided with a rectangular hole H that communicates the indoor space V1 side and the outdoor space V2 side. A window frame portion 403 is provided on the wall portion 402 along the edge of the hole portion H. The magic mirror unit 101 is fitted into the window frame portion 403. At this time, the illumination unit 301 is disposed along the upper edge of the window frame unit 403. Further, the metal thin film layer 203 is directed to the indoor space V1 side. Accordingly, the protruding portion 305 of the housing 303 protrudes from the wall portion 402 toward the outdoor space V2 side.

  Thus, in the window structure 401 of the present embodiment, the illuminating body 302 is turned on to brighten the outdoor space V2 side (second surface 204), and the magic mirror M is placed on the plate-like portion 201 even at night. Function can be demonstrated. Accordingly, it is possible to secure a view scenery from the indoor space V1 and prevent peeping from the outdoor space V2 during both daytime and nighttime.

  Another embodiment will be described with reference to FIG. For convenience of explanation, this embodiment will be referred to as a third embodiment. Here, the same reference numerals are given to the same parts as those of the embodiments described so far, and the description thereof is omitted. The present embodiment is an application example in which the magic mirror unit of the first embodiment is used for a handrail (veranda handrail).

  FIG. 3 is a schematic view of the handrail 501 viewed from the outdoor space V2 side. The handrail 501 constitutes a veranda (not shown) protruding from a building such as a detached house or an apartment. The veranda has a floor portion 502 and a handrail 501 standing from the floor portion 502. Residents exiting the building entrance can stay on the floor 502. The handrail 501 prevents a resident staying on the floor 502 from falling from the veranda.

  The handrail 501 includes a wall portion 503 and a plurality of magic mirror units 101 (see the first embodiment). The wall portion 503 corresponds to the wall portion 402 in the second embodiment. The floor portion 502 extends horizontally from the wall portion 503 toward the indoor space V1 side (the back side of the paper surface in FIG. 3).

  The wall portion 503 is provided with a plurality of rectangular holes H that communicate the indoor space V1 side and the outdoor space V2 side in a horizontal direction. The magic mirror unit 101 is fitted into each hole H. At this time, similarly to the window structure 401 in the second embodiment, the illumination unit 301 is located above the plate-shaped unit 201 and is directed toward the metal thin film layer 203 indoor space V1 side. Protrudes from the wall 402 toward the outdoor space V2 side. Here, a window frame portion (see the first embodiment) may be provided between the wall portion 503 and the magic mirror unit 101.

  Thus, in the handrail 501 of the present embodiment, the illumination body 302 is turned on to brighten the outdoor space V2 side (second surface 204), and the magic mirror M is formed on the plate-like portion 201 even at night. The effect of can be demonstrated. Accordingly, it is possible to secure a view scenery from the indoor space V1 and prevent peeping from the outdoor space V2 during both daytime and nighttime.

  Another embodiment will be described with reference to FIG. For convenience of explanation, this embodiment will be referred to as a fourth embodiment. The present embodiment relates to a magic mirror unit. The same parts as those in the first embodiment described above are denoted by the same reference numerals, and description thereof is omitted.

  FIG. 4 is a schematic view of the magic mirror unit 101A as viewed in cross section. The magic mirror unit 101A of the present embodiment includes a plate-like portion 201 and an illumination portion 301A.

  The illumination unit 301A includes a light emitting unit 301Aa, a diffusion unit 301Ab, and a reflection unit 301Ac. The light emitting unit 301 </ b> Aa is disposed on the upper part of the plate-like unit 201. The diffusion unit 301Ab is disposed along the second surface 204. The reflective portion 301Ac is disposed below the plate-like portion 201.

  The light emitting unit 301Aa includes a lighting body 302, a housing 303A, and a control circuit (not shown). The housing 303 </ b> A is attached to the upper end surface of the plate-like portion 201 and houses the illumination body 302. The illuminating body 302 is disposed to face the upper end surface of the plate-like portion 201.

  The diffusing portion 301 </ b> Ab is a light-transmitting sheet and is attached to the second surface 204. In the diffusing portion 301Ab, the reflective particles 306 are included in a dispersed state. For example, silver particles are employed as the reflective particles 306. The light L that has passed through the substrate 202 through the upper end surface of the plate-like portion 201 from the illuminating body 302 and entered the 301 Ab is diffused by the reflective particles 306.

  The reflective portion 301Ac is attached to the lower end surface of the plate-like portion 201. For example, a plane mirror or a convex mirror is employed as the reflecting portion 301Ac. The reflective portion 301Ac deflects light L from the illuminating body 302 that has entered from the upper end surface of the plate-like portion 201 and passed through the base material 202 and reached the lower end surface of the base material 202 upward. The reflection portion 301Ac is directed in a direction that allows the incident light L to reach the diffusion portion 301Ab.

  When the magic mirror unit 101A of the present embodiment is used, the illuminator 302 is turned on when the indoor space V1 is brighter than the outdoor space V2 (for example, at night). The light L emitted from the illuminating body 302 is diffused and irradiated downward, and part of the light L directly enters the diffusion portion 301Ab and is diffused by the reflective particles 306. A part of the light is reflected by the magic mirror surface of the metal thin film layer 203 and enters the diffusion portion 301Ab to be diffused. Further, a part of the light is directly reflected by the reflecting portion 301Ac, enters the diffusing portion 301Ab, and is diffused.

  Thereby, the 2nd surface 204 becomes bright, and even at night, the plate-shaped part 201 can exhibit the function as the magic mirror M, and the indoor space V1 side cannot be visually recognized from the outdoor space V2 side. .

  In this embodiment, the diffusing portion 301Ab is a light-transmitting sheet, but the reflective particles 306 for diffusing light are dispersed on the second surface 204 side of the substrate 202. It may be one that has been fixed in place, or may be one in which a large number of fine protrusions are formed. The protrusions may be formed by surface treatment, vapor deposition, printing, or the like of the base material 202.

  Further, it may be a spot printed with a color that easily reflects light, such as a transparent color, white color, or silver color, by silk printing.

  In the silk printing, when a large number of spots are formed, the size of the spots in the portion far from the light source is preferably larger than that in the near portion, or the interval between the spots is narrowed. Furthermore, in order to enhance the diffusion effect, the shape of the spots to be printed may be an irregular shape such as a polygonal shape or a star shape in addition to a circular shape. Furthermore, in the ink to be used, an ink in which reflective particles are mixed in a transparent color may be used.

  In this embodiment, the metal thin film layer 203 is formed on the first surface 202a side of the base material 202 to form the magic mirror M. However, the film having the magic mirror function on the first surface 202a side of the base material 202 is used. Affixed with may also be used.

  As described above, according to the magic mirror unit 101A of the present embodiment, it is possible to secure the view scenery from the indoor space V1 and prevent the peep from the outdoor space V2 during both daytime and nighttime.

  Furthermore, according to the magic mirror unit 101A of the present embodiment, the housing 303A does not have the protruding portion 305 (see FIG. 1), and the field of view seen from the indoor space V1 through the plate-like portion 201 is further expanded. Further, there is no urging portion 305, and no dirt accumulates between the urging portion 305 and the plate-like portion 201. Furthermore, the situation where the ejection part 305 is damaged cannot occur.

  Furthermore, the magic mirror unit 101A of the present embodiment has a reflecting portion 301Ac. For this reason, the light L from the illuminating body 302 is guided to the diffusing portion 301Ab without waste, the second surface 204 side becomes brighter, and the peeping prevention from the outdoor space V2 is further ensured.

  Another embodiment will be described with reference to FIG. For convenience of explanation, this embodiment will be referred to as a fifth embodiment. The present embodiment relates to a magic mirror unit and is similar to the fourth embodiment. The same parts as those in the first embodiment or the fourth embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  FIG. 5 is a schematic view of the magic mirror unit 101B as viewed in cross section. In the magic mirror unit 101B of the present embodiment, a phosphorescent portion 301Bb is arranged along the second surface 204 instead of the diffusion portion 301Ab (see the fourth embodiment).

The phosphorescent portion 301 </ b> Bb is a sheet-like member having translucency and is attached to the second surface 204. In the phosphorescent part 301Bb, particulate luminous material 307 is contained in a dispersed state. A commercially available phosphorescent pigment can be used for the phosphorescent material 307, and for example, a high-intensity long persistence phosphorescent pigment N Luminova (registered trademark) manufactured by Nemoto Special Chemical Co., Ltd. is preferable. Light L from the illuminating body 302 that has passed through the upper end surface of the plate-like portion 201 and passed through the base material 202 is incident on the phosphorescent material 307. Light L from the illuminating body 302 deflected by the reflecting surface 301Ac on the reflecting surface of the metal thin film layer 203 or the lower surface of the base material 202 is also incident on the phosphorescent material 307. Furthermore, not only the light L from the illumination body 302 but also light (for example, sunlight) from the indoor space V1 and the outdoor space V2 is incident on the phosphorescent material 307.

  When using the magic mirror unit 101B of the present embodiment, the illuminator 302 is turned on, and the light L from the illuminator 302 is directly or via the reflective surface 202a of the metal thin film layer 203 or the reflective portion 301Ac. The light is incident on the light storage unit 301Bb. And even if the indoor space V1 becomes brighter than the outdoor space V2, the 2nd surface 204 becomes bright by the light-accumulation part 301Bb which light-emitted. As a result, the second surface 204 becomes brighter, and even at night, the plate-like portion 201 functions as the magic mirror M so that the outdoor space V2 side can be visually recognized from the indoor space V1 side. Thus, the inside of the indoor space V1 can be made invisible from the outdoor space V2 side. Note that the illumination body 302 may be turned off or turned on at night.

  As described above, according to the magic mirror unit 101B of the present embodiment, it is possible to secure the view scenery from the indoor space V1 and prevent the peep from the outdoor space V2 during both daytime and nighttime.

  When light is sufficiently incident on the phosphorescent unit 301Bb due to receiving sunlight in the daytime, the magic mirror unit 101B does not have to be provided with the illumination unit 301A. In this case, a power source for lighting the illumination body 302 of the illumination unit 301A is not necessary.

  Further, the reflective particles 306 (see the fourth embodiment) may be mixed together with the phosphorescent material 307 in the sheet-like phosphorescent portion 301B, or the phosphorescent material 307 (this embodiment) is incorporated in the base material 202. (See the fifth embodiment) and the reflective particles 306 (see the fourth embodiment) may be mixed. In this case, at night, the phosphorescent material 307 emits light and the indoor space V1 cannot be seen from the outdoor space V2. Even when the phosphorescent material 307 cannot store enough light due to irregular weather during the daytime, the illuminating body 302 can be turned on so that the indoor space V1 cannot be seen from the outdoor space V2.

  Another embodiment will be described with reference to FIG. For convenience of explanation, this embodiment will be referred to as a sixth embodiment. This embodiment relates to a magic mirror unit and basically conforms to the first embodiment. The same parts as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

  FIG. 6 is a schematic view of the magic mirror unit 101C as viewed in cross section. The magic mirror unit 101C of the present embodiment includes a plate-like portion 201 and an illumination portion 301C.

  The illumination unit 301C includes an organic EL illumination plate 308 and a control circuit 309. The organic EL lighting plate 308 is attached to the second surface 204. The control circuit 309 controls the voltage applied to the organic EL lighting plate 308. The organic EL lighting plate 308 is allowed to transmit light when no voltage is applied, and the entire plate shines evenly when a voltage is applied.

  When the magic mirror unit 101C of the present embodiment is used, a voltage is applied to the organic EL lighting plate 308 using the control circuit 309 when the indoor space V1 is brighter than the outdoor space V2 (for example, at night). As a result, the entire organic EL lighting plate 308 shines, the second surface 204 becomes bright, and even at night, the plate-like portion 201 functions as the magic mirror M, so that the indoor space can be seen from the outdoor space V2 side. The V1 side can be made invisible.

  FIG. 7 is a schematic view of the magic mirror unit 101D as viewed in cross section. The magic mirror unit 101D of the present embodiment includes a glass plate part 600 and an illumination part 301A.

  The illumination unit 301A includes a light emitting unit 301Aa, a diffusing unit 601, and a reflecting unit 301Ac. The light emitting unit 301 </ b> Aa is disposed on the upper part of the plate-like unit 201. The diffusion unit 601 is disposed on the surface of the second surface 204. The reflective portion 301Ac is disposed below the glass plate portion 600.

  The light emitting unit 301Aa includes an LED light emitter 302A, a housing 303A, and a control circuit (not shown). The housing 303A is attached to the upper end surface of the plate-like portion 201 and houses the LED light emitter 302A. The LED light emitter 302A is disposed to face the upper end surface of the glass plate portion 600.

  The diffusion part 601 is obtained by dispersing and fixing light diffusion particles on the second surface 204 in the form of spots. The light diffusing particles may be any as long as they diffuse light with respect to LED light. For example, paint, ink, glass particles, resinous particles, alumina particles, aluminum metal particles, silver particles, etc. are used. it can.

  The diffusing unit 601 of the present embodiment has spots formed by white ink on the surface of the second surface 204 of the glass plate unit 600, and circular spots having a diameter of 1 mm to 2 mm are spaced at intervals of 0.5 mm to 2 mm. Dispersed throughout and formed by silk printing.

  FIG. 8 shows an arrangement state of the spots 602 by the light diffusing particles in the diffusing unit 601. (The spots are white but are shown in black in the drawing.) The diameter of the spots 602 is about 1 mm at the uppermost part, and becomes larger as it goes to the lower part, and is about 2 mm at the lowermost part. As for the interval between the spots 602, the interval is wide (about 2 mm) in the upper part, and the interval is narrower (about 0.5 mm) toward the lower part.

  The light emitted from the LED light emitter 302A enters the inside through the upper end surface of the glass plate portion 400, and as indicated by the arrow L1, the diffusion portion 601 directly formed on the surface of the second surface 204. It diffuses and emits light toward the outdoor space V2 due to the spots 602 caused by the light diffusion particles.

  Further, a part of the light emitted from the LED light emitter 302A is reflected by the magic mirror surface of the metal thin film layer 203 as shown by the arrow L2, and is irradiated as reflected light on the second surface 204 side. And it diffuses by the spot 602 by the light-diffusion particle | grains of the spreading | diffusion part 601, and the outdoor space V2 side light-emits.

  Furthermore, a part of the light emitted from the LED light emitter 302A is reflected directly to the second surface 204 side by the reflecting portion 301Ac arranged at the bottom of the glass plate portion 600 as indicated by an arrow L3. In addition, a part of the light is reflected by the magic mirror surface of the metal thin film layer 203 and diffused by the speckles 602 due to the light diffusion particles of the diffusion portion 601, and the outdoor space V 2 side emits light.

  For example, a plane mirror or a convex mirror is employed as the reflecting portion 301Ac. The reflecting portion 301Ac is directed in such a direction that the light from the LED light emitter 302A is deflected upward and the incident light reaches the diffusing portion 601.

  When the magic mirror unit 101D of the present embodiment is used, the LED light emitter 302A is turned on when the indoor space V1 is brighter than the outdoor space V2 (for example, at night).

  The light L emitted from the LED light emitter 302A is diffused and irradiated downward, and directly or indirectly enters the diffusing unit 601, diffuses and emits light.

  Thereby, the 2nd surface 204 becomes bright, and even at night, the plate-shaped part 201 can exhibit the function as the magic mirror M, and the indoor space V1 side cannot be visually recognized from the outdoor space V2 side. .

  As shown in FIG. 3, the magic mirror unit 101D of the present embodiment is used to measure the illuminance of the inner surface of the metal thin film surface 402 and the outer surface of the second surface 204 in the veranda handrail of an apartment used as a handrail (veranda handrail).
