Detailed Description

Each of the embodiments below relates generally to a mirror and a mirror system, and more particularly to a mirror and a mirror system including a glass substrate, a reflective film, and a protective film.

(embodiment mode 1)

Fig. 1A, 1B, and 2 show the structure of the mirror 1 of embodiment 1, wherein the front side is an side where light is reflected by the mirror 1 and a virtual image is visible, and the back side is a side where the virtual image is not visible, and in the following description, unless otherwise specified, each direction of the left and right, and the up and down is defined in fig. 1A.

The mirror 1 includes a glass substrate 2, a reflective film 3, and a protective film 4 as a main structure.

The glass substrate 2 is a glass plate having a predetermined thickness and transmitting light. The shape and the width of the glass substrate 2 at the time of the main view determine the shape and the width of the mirror 1 at the time of the main view. The front surface 21 and the back surface 22 of the glass substrate 2 are flat.

The thickness of the glass substrate 2 is not particularly limited, and the thickness of the glass substrate 2 is preferably , but the thickness of the glass substrate 2 may not be , and the flatness of the front surface 21 and the back surface 22 of the glass substrate 2 is preferably as high as possible, but the flatness is not limited to a specific value or range, and a portion having a lower flatness than the other portion may be present in the portion in the main view of the front surface 21 or the back surface 22 of the glass substrate 2, and the composition of the glass substrate 2 is not particularly limited, and the front surface 21 or the back surface 22 of the glass substrate 2 may be a curved surface.

The reflective film 3 is provided on the back surface 22 of the glass substrate 2, and the front surface 31 of the reflective film 3 is in contact with the back surface 22 of the glass substrate 2. as the reflective film 3, it is preferable to use a film composed of a silver film provided directly on the back surface 22 of the glass substrate 2 and a copper film provided on the back surface of the silver film. the reflective film 3 is preferably provided over the entire back surface 22 of the glass substrate 2, but it is not limited to .

The protective film 4 is provided on the back surface 32 of the reflective film 3, and the front surface 41 of the protective film 4 is in contact with the back surface 32 of the reflective film 3. as the protective film 4, a film made of a resin is preferably used, and the protective film 4 is preferably provided over the entire back surface 32 of the reflective film 3, but the protective film 4 may be provided over the entire back surface without being limited, and the material of the protective film 4 is not limited to a resin, and a known material of the protective film may be suitably used.

As described above, the mirror 1 is formed by laminating the glass substrate 2, the reflective film 3, and the protective film 4 in the thickness direction.

In fig. 1A, the mirror 1 has a rectangular shape in front view, and a translucent portion 5 is provided at the lower left corner in front view. The light transmitting portion 5 includes a plurality of (many) fine light transmitting through holes 51 formed in the reflective film 3 and the protective film 4. The light-transmitting through-hole 51 is formed by a so-called silver-removed portion from which the reflective film 3 and the protective film 4 are removed. The silver-removed portion is a hollow space where the reflective film 3 and the protective film 4 are not present, and is formed along the thickness direction of the reflective film 3 and the protective film 4. Hereinafter, the through hole for light transmission is simply referred to as a through hole.

The through hole 51 of the present embodiment is formed in a cylindrical shape with the thickness direction of the mirror 1 being the axial direction, and a circular 1 st opening 511 is formed in the front surface 31 of the reflective film 3, and a circular 2 nd opening 512 is formed in the rear surface 42 of the protective film 4. That is, the through-hole 51 includes circular 1 st and 2 nd openings 511 and 512 at both ends in the thickness direction of the mirror 1, respectively, the 1 st opening 511 being closed by the back surface 22 of the glass substrate 2, and the 2 nd opening 512 being open on the back surface side of the mirror 1.

The through hole 51 is cylindrical, the diameter of the 1 st opening 511 is equal to the diameter of the through hole 51, the diameter of the 1 st opening 511 is equal to the width L1 of the 1 st opening 511, the width L1 is along the direction of the surface 31 of the reflective film 3 (here, the direction of the diameter of the 1 st opening 511), and in the present embodiment, the width L1 is set in the range of 0.01[ mm ] to 1[ mm ].

Such through-hole 51 forms a path (optical path) through which light passes between the front surface 31 side of the reflective film 3 and the back surface 42 side of the protective film 4. The glass substrate 2 has optical transparency, and light incident on the light-transmitting portion 5 from the front surface side of the mirror 1 is emitted to the back surface side of the mirror 1 through the glass substrate 2 and the through hole 51. Light entering the light-transmitting portion 5 from the rear surface side of the mirror 1 is emitted to the front surface side of the mirror 1 through the through hole 51 and the glass substrate 2.

In the present embodiment, the light transmitting portion 6 is disposed on the rear surface side of the light transmitting portion 5 (see fig. 1B). The lighting unit 6 includes a light Emitting element such as an led (light Emitting diode), and can be switched between lighting and turning off. When the lighting portion 6 is turned on, the visible light passing through the light transmitting portion 5 is visible from the front surface side of the mirror 1, and can be recognized by the user as illumination or some kind of display. For example, when an illumination device that irradiates visible light to the front surface side of the mirror 1 with light emitted from an LED is used as the lighting portion 6, the light-transmitting portion 5 functions as a light-emitting surface. In addition, when a display device that displays a message, the current time, and the like by the light emission of the segment LEDs is used as the lighting portion 6, the light-transmitting portion 5 functions as a display surface on which the message, the current time, and the like are displayed.

In fig. 1A, the plurality of through holes 51 are arranged in a rectangular shape, and the light transmitting portion 5 is formed in a rectangular shape, and fig. 3A is a front view showing a portion of the reflection film 3 including the light transmitting portion 5, and fig. 3B is a front view showing a portion region 50 (see fig. 3A) of the light transmitting portion 5, in fig. 3A and 3B, the plurality of through holes 51 are regularly arranged in a lattice shape, and a predetermined number of through holes 51 arranged in rows in the left-right direction constitute 1 row, and the plurality of rows are arranged in the up-down direction.

That is, the 1 st opening 511 (the 1 st openings 511) of the through holes 51 is arranged in a rectangular shape on the surface 31 of the reflective film 3. The diameter of the 1 st opening 511 (the width dimension L1 of the 1 st opening 511) is set to be in the range of 0.01[ mm ] or more and 1[ mm ] or less.

Furthermore, each of the 1 st openings 511 is disposed on the surface 31 of the reflective film 3 so that the distance W from the adjacent 1 st opening 511 is 0.01[ mm ] to 2[ mm ]. That is, the distance W of the adjacent 21 st openings 511 among the plurality of 1 st openings 511 is included in a range of 0.01[ mm ] or more and 2[ mm ] or less, and the density of the 1 st openings 511 in the surface 31 is determined by the distance W.

When the lighting unit 6 is turned on, light emitted from the lighting unit 6 and incident on the 2 nd opening 512 of the through hole 51 passes through the inside of the through hole 51, is emitted from the 1 st opening 511 to the outside of the through hole 51, and is emitted from the front surface side of the mirror 1 through the glass substrate 2. In this case, the amount of light emitted from the 1 st opening 511 is relatively small. However, the light transmission section 5 includes a large number of 1 st openings 511, and the distance W between adjacent 21 st openings 511 is included in a range of 0.01[ mm ] to 2[ mm ]. That is, the density of the 1 st openings 511 on the surface 31 of the reflective film 3 is set so that the light passing through the light transmitting portion 5 (the plurality of 1 st openings 511) has a sufficient amount of light and brightness to be recognized by the user. Therefore, when the lighting portion 6 is turned on, the light emitted from the light transmitting portion 5 on the surface 31 of the reflective film 3 becomes a sufficient amount of light and brightness to be recognized by a user on the surface side of the mirror 1.

When the lighting portion 6 is turned off, the light of the lighting portion 6 is not emitted from the 1 st opening 511. The diameter (width L1) of the 1 st opening 511 of the through-hole 51 is set to a value at which the 1 st opening 511 is less likely to be noticeable when viewed from the user. Specifically, the diameter of the 1 st opening 511 is set to be in the range of 0.01[ mm ] to 1[ mm ]. Therefore, the 1 st opening 511 which does not emit light becomes a minute spot on the surface 31 of the reflective film 3 to such an extent that it is difficult for a user present on the surface side of the mirror 1 to recognize it. As a result, when the lighting portion 6 is turned off, the light transmitting portion 5 (the plurality of 1 st openings 511) does not stand out on the surface 31 of the reflective film 3, and the function as a mirror surface of the light transmitting portion 5 becomes substantially equal to that of the surface 31 of the reflective film 3 on which the light transmitting portion 5 is not formed.

As described above, the mirror 1 is provided with the light transmitting portion 5 at the portion in the main view, and the light transmitting portion 5 is provided with the plurality of through holes 51 (the plurality of silver removing portions) for removing the reflective film 3 and the protective film 4 in the main view, and the plurality of through holes 51 are arranged discretely, and as a result, the light transmitting portion 5 functions as a pseudo half mirror, and is less noticeable when the lighting portion 6 is extinguished, and has high recessed and shielding properties, that is, the mirror 1 is less noticeable at the light transmitting portion 5 having light transmitting properties, and can secure the function of the light transmitting portion 5 as a mirror surface.

Specifically, since the reflection film 3 remains in the region other than the through hole 51 in the front view of the mirror 1, the transparent portion 5 functions as a half mirror that can realize a simulation of a natural mirror surface with less sense of torsion than the surrounding region, and therefore, the mirror 1 can improve design properties as compared with the conventional technique in which a transparent portion is formed by 1 through hole (1 silver removed portion) having a relatively large size and the conventional technique in which a transparent portion is formed by a half mirror film that reflects part of light and transmits the remaining light.

In addition, since the transparent portion 5 functions as a natural mirror surface in the mirror 1 of the present embodiment, it is possible to suppress a decrease in the main quality (color tone, brightness, shape, and the like of a virtual image) of the mirror while providing the transparent portion 5, in particular, the transparent portion 5 having the plurality of through holes 51 has a better color tone of a virtual image than in the conventional technique in which the transparent portion is formed of a half mirror film, and further, in the mirror 1, the transparent portion 5 is formed only in the portion in the main view, so that a portion other than the transparent portion 5 can be used in makeup.

Further, in the case where the transparent portion 5 is formed by the plurality of through holes 51, the transparent portion 5 can be formed relatively easily, and the transparent portion 5 can be formed at an arbitrary position at low cost, and in the other , if the portion in the main view is formed as the half mirror film, the manufacturing process becomes very complicated, and the cost increases.

Further, since the transparent portion 5 functioning as a pseudo half mirror having an arbitrary shape is formed only by performing the removal process of the reflective film 3 and the protective film 4 on the known mirror including the glass substrate 2, the reflective film 3, and the protective film 4, the cost reduction and the general use of the mirror 1 can be realized. The transmittance (average transmittance) of the translucent portion 5 as a pseudo half mirror is determined by the ratio of the total area of the 1 st opening 511 to the area other than the 1 st opening 511 in the translucent portion 5 of the surface 31.

Further, since the distance W between the adjacent 21 st openings 511 is included in the range of 0.01[ mm ] to 2[ mm ], it is possible to sufficiently secure the total amount of light passing through the light-transmitting portion 5 while securing the recessiveness of the light-transmitting portion 5.

The total light amount of the light passing through the light transmission section 5 is defined by a combination of the width L1 of the 1 st opening 511 and the distance W. Generally, as the width dimension L1 and the separation distance W are close to the wavelength of visible light, the geometrical-optical (ray) property becomes weaker and the scattering (Mie scattering) property becomes stronger. Therefore, if the width L1 and the separation distance W are too small, the light-transmitting portion 5 is likely to be whitened like a scattering surface.

Therefore, in the present embodiment, the lower limit of the width L1 is set to 0.01[ mm ] so as to be less susceptible to scattering. Specifically, since the upper limit of the wavelength of visible light is about 1[ μm ], 0.01[ mm ], which is 10 times as large as 1[ μm ], is set as the lower limit of the width L1.

The values of the width L1 and the distance W (the combination of the width L1 and the distance W) are preferably set such that the light transmittance of the light-transmitting portion 5 is 5 to 50 [% ] (the reflectance of the light-transmitting portion 5 is 50 to 95 [% ]).

Further, instead of the lighting unit 6, a sensor for detecting a predetermined object or a receiving device for receiving a light signal may be disposed on the back surface side of the light transmission unit 5. The sensor is a motion sensor or a human body sensor, etc. The motion sensor irradiates light (infrared light, visible light, or the like) to the front surface side of the mirror 1, receives the reflected light, and detects the motion of the user existing on the front surface side of the mirror 1. The human body sensor receives infrared rays and detects a user present on the front surface side of the mirror 1. The lighting and extinguishing of the lighting unit 6 may be switched according to the detection result of the sensor. Further, the receiving device receives an optical signal (infrared ray, visible light, or the like) for controlling the target apparatus from a remote controller or the like.

In this case, the light passing through the light transmitting portion 5 is a sufficient amount of light to allow the motion sensor, the human body sensor, and the receiving device to function. Further, since the light transmitting portion 5 is not conspicuous on the surface 31 of the reflective film 3 as in the above, the function of the light transmitting portion 5 as a mirror surface portion is substantially equivalent to the surface 31 of the reflective film 3 on which the light transmitting portion 5 is not formed. That is, the mirror 1 can ensure the light transmittance of the light transmitting portion 5, and can ensure the function as a mirror surface of the light transmitting portion 5 by making the light transmitting portion 5 less noticeable.

Next, fig. 4A and 4B show a 1 st modification example relating to the arrangement of the 1 st openings 511 (through holes 51) in the light transmitting portion 5, respectively, in fig. 4A, a predetermined number of the 1 st openings 511 (through holes 51) arranged in the lateral direction as rows constitute 1 row, and a plurality of rows are arranged in the vertical direction, and in pairs of rows adjacent in the vertical direction, the 1 st openings 511 (through holes 51) are regularly arranged in a staggered shape, and in fig. 4B, the plurality of the 1 st openings 511 (through holes 51) are irregularly arranged.

Further, as in the 2 nd modification shown in fig. 5, the plural 1 st openings 511 may be arranged in the surface 31 of the reflection film 3 so as to have a predetermined shape such as a character, a symbol, or a figure, the character is, for example, a roman alphabet, a hiragana, a katakana, a kanji, a numeral, or the like, the symbol is various icons, indexes, symbols, a histogram, or the like, and the figure is a circle, a triangle, a quadrangle, or the like, as a result, when the lighting part 6 is lit, of the character, the symbol, and the figure are displayed on the surface of the mirror 1 by lighting the lighting part 6 alone even if the mirror 1 does not have a light-shielding sign, and messages such as a notification, an instruction, and a report can be transmitted to the user, and further, since the area of the light-transmitting part 5 can be made smaller, the light-transmitting part 5 becomes less conspicuous, and the concealing property of the light-transmitting part 5 is improved.

As a modification 3, the plurality of 1 st openings 511 provided in the light transmission section 5 may be arranged along the outline (outline) of a predetermined shape.

For example, as shown in fig. 6A, the plurality of 1 st openings 511 provided in the light transmission section 5 include 2 or more outer openings 511a and 2 or more inner openings 511 b. The outer openings 511a are arranged along the outline (outline) of a predetermined shape such as a character, a symbol, or a figure. The inner opening 511b is disposed inside the outline formed by the outer opening 511 a.

Further, it is preferable that each of the outer openings 511a is disposed on the surface 31 of the reflective film 3 so that the distance W from the adjacent 1 st opening 511a is in the range of 0.01[ mm ] to 5[ mm ]. That is, the distance W between the adjacent 21 st openings 511a is set to 0.01[ mm ] to 5[ mm ]. In this case, the outer opening 511a is disposed along the outline of the predetermined shape, and the outline of the predetermined shape becomes clear, thereby improving the design of the light-transmitting portion 5 for emitting light. Further, since the outer opening 511a is arranged along the outline, even if the distance W is 5[ mm ], a person can easily imagine a predetermined shape.

Further, each of the inner openings 511b is preferably disposed on the surface 31 of the reflective film 3 so that the distance W from the adjacent 1 st opening 511b is in the range of 0.01[ mm ] to 2[ mm ]. That is, the distance W between the adjacent 2 inner openings 511b is set to 0.01[ mm ] to 2[ mm ].

As shown in fig. 6B, the plurality of 1 st openings 511 provided in the light transmission section 5 may be arranged only along the outline (outline) of a predetermined shape to be displayed. In this case, the 1 st openings 511 are preferably arranged so that the distance W from the adjacent 1 st opening 511 on the surface 31 of the reflective film 3 is in the range of 0.01[ mm ] to 5[ mm ]. Further, all the 1 st openings 511 provided in the light transmission portion 5 are arranged along the outline of the predetermined shape, so that the outline of the predetermined shape becomes clear, the design of the light transmission portion 5 that emits light is improved, the light transmission portion 5 becomes less conspicuous, and the recessed property of the light transmission portion 5 is improved.

Fig. 7A and 7B show a 4 th modification example relating to the shape of a light-transmitting through hole (1 st opening) provided in the light-transmitting portion 5.

The light transmission portion 5 of fig. 7A includes a plurality of through holes 52 for light transmission. The through hole 52 is formed in an elliptical columnar shape with the thickness direction of the mirror 1 being the axial direction, and an elliptical 1 st opening 521 is formed in the front surface 31 of the reflective film 3, and an elliptical 2 nd opening is also formed in the rear surface 42 of the protective film 4. The through hole 52 is in an elliptical cylinder shape, and the short diameter of the 1 st opening 521 is equal to the short diameter of the through hole 52. The minor axis of the 1 st opening 521 is set in the range of 0.01[ mm ] to 1[ mm ] corresponding to the width L1 of the 1 st opening 521. Further, the distance W between the adjacent 21 st openings 521 is in the range of 0.01[ mm ] to 2[ mm ].

In fig. 7A, the through holes 52 are regularly arranged in a lattice shape. However, the arrangement of the plurality of through holes 52 is not limited to a specific arrangement, and may be staggered or irregularly arranged as long as the above-described distance W is included in a range of 0.01[ mm ] to 2[ mm ].

The light transmitting portion 5 in fig. 7B includes a plurality of straight light transmitting through holes 53. The through hole 53 has a rectangular shape, and a rectangular 1 st opening 531 is formed in the front surface 31 of the reflective film 3, and a rectangular 2 nd opening is also formed in the rear surface 42 of the protective film 4. The through hole 53 has a rectangular shape, and the dimension of the 1 st opening 531 in the shorter direction is equal to the dimension of the through hole 53 in the shorter direction. The dimension of the 1 st opening 531 in the shorter direction is set in the range of 0.01[ mm ] to 1[ mm ] corresponding to the width dimension L1 of the 1 st opening 531. Further, the distance W between the adjacent 21 st openings 531 is in the range of 0.01[ mm ] to 2[ mm ].

In fig. 7B, the through holes 53 are regularly arranged at equal intervals in the left-right direction. However, the arrangement of the plurality of through holes 53 may be irregular as long as the above-mentioned distance W is included in a range of 0.01[ mm ] to 2[ mm ], and is not limited to a specific arrangement.

The shape of the 1 st opening may be other than circular, elliptical, or rectangular. That is, the 1 st opening is not limited to a specific shape as long as the width L1 is set within a range of 0.01[ mm ] to 1[ mm ].

As a modification 5, the light-transmitting portion 5 may have a plurality of 1 st openings having different shapes, for example, as shown in fig. 6C, the light-transmitting portion 5 may have a circular 1 st opening 511 formed inside a predetermined shape to be displayed and a linear (linear or curved) 1 st opening 541 formed along the outline (outline) of the predetermined shape, in which case the outline of the predetermined shape becomes clearer and the design of the light-emitting light-transmitting portion 5 is further improved by .

Next, fig. 8 shows a 6 th modification of the structure of the light transmitting portion 5.

In the above-described embodiment, the inside of the light-transmitting through hole 51 is hollow, and the end surface (edge) of the reflective film 3 is exposed on the side surface of the through hole 51, so that there is a possibility that rust or the like may be generated on the end surface of the reflective film 3 to cause corrosion. Therefore, as shown in fig. 8, it is preferable to form a transparent or translucent protective film 9 having light transmittance on the rear surface 42 side of the protective film 4, and form the protective film 9 inside the through hole 51. In this case, the through hole 51 is filled with the light-transmitting protective film 9, and the cavity inside the through hole 51 can be eliminated to discharge air. Therefore, the end face of the reflective film 3 is covered with the protective film 9, and therefore, the occurrence of corrosion can be suppressed. The light-transmitting protective film 9 can be applied to other modifications.

In the 7 th modification shown in fig. 9, the mirror 1 includes a plurality of light transmitting portions 5. The light transmittance of each of the plurality of light transmitting portions 5 can be individually set in accordance with the shape of the 1 st opening (the shape of the light transmitting through hole), the width L1, the distance W, and the like. That is, the light transmittance of each of the plurality of light transmitting portions 5 is individually set according to the purpose of each of the plurality of light transmitting portions 5.

For example, the light-transmitting portion 5 as a light-emitting surface or a display surface that emits visible light to the front surface side of the mirror 1, the light-transmitting portion 5 as a transmitting surface or a receiving surface through which light transmitted or received by a sensor passes, the light-transmitting portion 5 as a light-receiving surface on which an optical signal such as infrared light is incident from a remote controller, and the like, transmittance suitable for each application of the light-transmitting portion 5 may be set for each light-transmitting portion 5.

Further, the light distribution characteristics of each of the plurality of light transmission portions 5 may be individually set according to the purpose of each of the plurality of light transmission portions 5.

As a method of forming the light-transmitting through holes such as the through holes 51, 52, and 53 in the mirror 1, a method may be employed in which the reflective film 3 and the protective film 4 are not formed in the portions to be the through holes 51, 52, and 53 in the manufacturing process of forming the reflective film 3 and the protective film 4 on the glass substrate 2. As such a method, for example, a masking method may be employed in which, when the reflective film 3 and the protective film 4 are formed on the glass substrate 2, portions to be the through holes 51, 52, and 53 are masked so that the reflective film 3 and the protective film 4 are not formed. When the masking method is used, the back surface 22 of the glass substrate 2 facing the through holes 51, 52, and 53 is easily made flat without roughness. In the case of adopting the method in which the reflective film 3 and the protective film 4 are not formed at the portions to be the through holes 51, 52, and 53 in this way, the step of forming the mirror 1 includes the step of forming the through holes 51, 52, and 53.

The mirror 1A includes a glass substrate 2, a reflective film 3, and a protective film 4 as a main structure.

The glass substrate 2 is a glass plate having a predetermined thickness and transmitting light. The shape and the width of the glass substrate 2 at the time of main view determine the shape and the width of the mirror 1A at the time of main view. The front surface 21 and the back surface 22 of the glass substrate 2 are flat.

The thickness of the glass substrate 2 is not particularly limited, and the thickness of the glass substrate 2 is preferably , but the thickness of the glass substrate 2 may not be but , and the flatness of the front surface 21 and the back surface 22 of the glass substrate 2 is preferably as high as possible, but the flatness is not limited to a specific value or range, and a portion with a lower flatness may be present in the portion of the front surface 21 or the back surface 22 of the glass substrate 2 in a main view than the other portion, the composition of the glass substrate 2 is not particularly limited, and the front surface 21 or the back surface 22 of the glass substrate 2 may be a curved surface.

The reflective film 3 is provided on the back surface 22 of the glass substrate 2, and the front surface 31 of the reflective film 3 is in contact with the back surface 22 of the glass substrate 2. As the reflective film 3, a film composed of a silver film provided directly on the back surface 22 of the glass substrate 2 and a copper film provided on the back surface of the silver film is suitably used, and the reflective film 3 is preferably provided over the entire back surface 22 of the glass substrate 2, but may be provided over the entire back surface without being limited thereto, and furthermore, the reflective film 3 is not limited to silver or copper, and a known reflective film material typified by other metals may be suitably used, and the film thickness of the reflective film 3 in the present embodiment is about 10[ μm ], but specific values are not particularly limited.

The protective film 4 is provided on the back surface 32 of the reflective film 3, and the front surface 41 of the protective film 4 is in contact with the back surface 32 of the reflective film 3. as the protective film 4, a film made of a resin is suitably used, and the protective film 4 is preferably provided over the entire back surface 32 of the reflective film 3, but may not be provided over .

As described above, the mirror 1A is formed by laminating the glass substrate 2, the reflective film 3, and the protective film 4 in the thickness direction.

In fig. 10A, the mirror 1A has a rectangular shape in front view, and a translucent portion 5 is provided at the lower left corner in front view. As shown in fig. 11A, the light transmitting portion 5 includes 1 light transmitting through hole 51A formed in the reflective film 3 and the protective film 4. The light-transmitting through-hole 51A is formed by a so-called silver-removed portion where the reflective film 3 and the protective film 4 are removed. The silver-removed portion is a hollow space where the reflective film 3 and the protective film 4 are not present, and is formed along the thickness direction of the reflective film 3 and the protective film 4. Hereinafter, the through hole for light transmission is simply referred to as a through hole.

Such through-hole 51A forms a path (optical path) through which light passes between the front surface 31 side of the reflective film 3 and the back surface 42 side of the protective film 4. The glass substrate 2 has optical transparency, and light entering the light-transmitting portion 5 from the front surface side of the mirror 1A is emitted to the back surface side of the mirror 1A through the glass substrate 2 and the through hole 51A. Light entering the light-transmitting portion 5 from the rear surface side of the mirror 1A is emitted to the front surface side of the mirror 1A through the through hole 51A and the glass substrate 2.

In the through hole 51A of the present embodiment, a circular 1 st opening 511 is formed in the front surface 31 of the reflective film 3, and a circular 2 nd opening 512 is formed in the rear surface 42 of the protective film 4. That is, the through-hole 51A includes a circular 1 st opening 511 and a circular 2 nd opening 512 at both ends in the thickness direction of the mirror 1A, the 1 st opening 511 is closed by the back surface 22 of the glass substrate 2, and the 2 nd opening 512 is open on the back surface side of the mirror 1A.

The 1 st opening 511 and the 2 nd opening 512 are formed in a coaxial circular shape so that an imaginary axis extending in the thickness direction of the mirror 1A passes through the center. The diameter of the 2 nd opening 512 is larger than that of the 1 st opening 511. That is, in the front view, the 1 st opening 511 and the 2 nd opening 512 are formed concentrically so that the peripheral edge of the 2 nd opening 512 surrounds the outer side of the peripheral edge of the 1 st opening 511, and the area of the 2 nd opening 512 is larger than the area of the 1 st opening 511.

Specifically, the through-hole 51A includes a 1 st space 61 formed in the reflective film 3 and a 2 nd space 62 formed in the protective film 4, the 1 st space 61 is a cylindrical shape passing through between the front surface 31 and the back surface 32 of the reflective film 3, an end of the 1 st space 61 is a 1 st opening 511, the 2 nd space 62 is a cylindrical shape passing through between the front surface 41 and the back surface 42 of the protective film 4, and a end of the 2 nd space 62 is a 2 nd opening 512, and the 2 nd space 62 has a larger diameter than the 1 st space 61, a step 513 is formed at a boundary between the reflective film 3 and the protective film 4, and a diameter of the through-hole 51A changes stepwise at the boundary between the reflective film 3 and the protective film 4, in other words, if the through-hole 51A is close to the 2 nd opening 512 from the 1 st opening 511, a cross-sectional area (a cross-sectional area in a plane direction of the mirror 1A) orthogonal to a thickness direction becomes large stepwise at the step 513, and in this case, the step 513 is located at a boundary between the reflective film 3 and the protective film 4, and therefore, the.

In the present embodiment, the light receiving section 7 is disposed on the rear surface side of the light transmitting section 5. In this case, the mirror system 10 includes the mirror 1A and the light receiving unit 7.

The light receiving unit 7 is provided in a human detection sensor, a receiving device, or the like, and receives infrared light as light emitted from the front side of the mirror 1A (the surface side of the mirror 1A). For example, in a pyroelectric type human body sensor, the light receiving unit 7 includes a pyroelectric element, and the light receiving unit 7 receives infrared light emitted from a user present in front of the mirror 1A (on the front surface side of the mirror 1A). The pyroelectric type human body sensor detects the presence or movement of the user based on the infrared light received by the light receiving unit 7. In the receiving device, the light receiving unit 7 receives infrared light transmitted from a remote controller (transmitting device) located in front of the mirror 1A (on the front surface side of the mirror 1A). The receiving device demodulates the transmission signal from the remote controller based on the infrared light received by the light receiving unit 7. That is, the light receiving unit 7 receives the infrared light that has passed through the light transmitting unit 5 from the front surface side of the mirror 1A. The light receiving unit 7 may be provided in a device other than the human detection sensor and the receiving device, and the received light may be light other than infrared light.

Here, if the travel angle, which is the angle of the travel direction of the light with respect to the normal line of the surface 31 of the reflective film 3, is θ (see fig. 11A), the detection angle of the light receiving unit 7 is determined by the range of the travel angle θ of the light that can pass through the light transmitting portion 5 (through hole 51A). Therefore, in order to widen the detection angle of the light receiving unit 7, it is effective to widen the range of the travel angle θ of the light that can pass through the light transmitting unit 5 (the through hole 51A). The travel angle theta is in the range of 0 DEG to 90 DEG inclusive. The detection angle of the light receiving unit 7 corresponds to the detection angle of a human detection sensor, a receiving device, or the like provided with the light receiving unit 7.

Therefore, in the through-hole 51A of the present embodiment, if the 1 st opening 511 is close to the 2 nd opening 512, the sectional area of the through-hole 51A becomes large in stages. As a result, the range of the travel angle θ of the light that can pass through the through-hole 51A can be widened.

The operational effects of the through-hole 51A will be described in detail below.

First, fig. 12 shows portions of a mirror 100 according to a comparative example of the present embodiment, in which the mirror 100 includes a through hole 200, the through hole 200 is formed in a cylindrical shape with the thickness direction of the mirror 100 being the axial direction, a circular 1 st opening 201 is formed in the front surface 31 of the reflective film 3, and a circular 2 nd opening 202 is formed in the rear surface 42 of the protective film 4, that is, the through hole 200 includes circular 1 st and 2 nd openings 201 and 202 at both ends in the thickness direction of the mirror 100, respectively, the 1 st opening 201 is closed by the rear surface 22 of the glass substrate 2, and the 2 nd opening 202 is open on the rear surface side of the mirror 100, and the diameter of the 1 st opening 201 is equal to the diameter of the 2 nd opening 202, and a space having a cylindrical shape is formed between the 1 st opening 201 and the 2 nd opening.

Further, a light receiving unit 7 is disposed on the rear surface side of the mirror 100 so as to face the 2 nd opening 202.

When the travel angle θ of light is larger than 0[ ° ], if the 1 st opening 201 is viewed from the front surface side of the mirror 1A in the direction of the travel angle θ, at least parts of the path from the 1 st opening 201 to the back surface side of the mirror 1A may be blocked by the protective film 4 (end surface of the protective film 4) on the side surface of the through-hole 200, that is, when the travel angle θ of light is larger than 0[ ° ], at least parts of light incident into the through-hole 200 from the 1 st opening 201 may strike the protective film 4 on the side surface of the through-hole 200 and be blocked by light.

Here, let Db be the diameter of the 1 st opening 201 (the diameter of the through hole 200), Hb. be the sum of the film thickness of the reflective film 3 and the film thickness of the protective film 4 (film thickness dimension), and when the 1 st opening 201 is viewed from the front surface side of the mirror 1A in the direction of the travel angle θ 1, if the -half region of the 1 st opening 201 is blocked by the protective film 4, Db is 2Hb × tan (θ 1) holds, and when the diameter Db of the 1 st opening 201 is small and Db is equal to or less than 5.5 × Hb, the maximum travel angle θ m2 is 70[ ° ] or less, and the detection angle of the light receiving unit 7 becomes relatively narrow, that is, when the film thickness dimension Hb is , the diameter Db of the 1 st opening 201 becomes smaller, and the detection angle of the light receiving unit 7 becomes narrower.

On the other hand, in , as shown in fig. 11A, if the through-hole 51A of the present embodiment is closer to the 2 nd opening 512 from the 1 st opening 511, the sectional area becomes larger in steps 513, that is, the end surface of the protective film 4 is located more outside than the end surface of the reflective film 3 in the through-hole 51A, and the end surface of the protective film 4 is less visible from the 1 st opening 511, therefore, in the through-hole 51A, even if the traveling angle θ of the light incident into the through-hole 51A is large, the light is not easily blocked by the protective film 4, and the maximum traveling angle θ m1, which is the maximum value of the traveling angle θ of the light that can pass through the through-hole 51A, becomes larger than the maximum traveling angle θ m2 of the through-hole 200, and as a result, the range of the traveling angle θ of the light that can pass through the through-hole 51A becomes wider than the range of the traveling angle θ of the light that.

If the diameter of the 1 st opening 511 is Da and the sum of the film thickness of the reflective film 3 and the film pressure of the protective film 4 (film thickness dimension) is Ha, the above-described structure of the through-hole 51A is particularly effective when the diameter Da of the 1 st opening 511 is small and Da is not more than 5.5 × Ha.

The maximum travel angle θ m1 is preferably set to about 60[ ° ]. Specifically, if the difference Ra between the radius of the 1 st opening 511 and the radius of the 2 nd opening 512 is 1.7 × Ha or more, the maximum travel angle θ m1 can be set to about 60[ ° ].

As shown in fig. 13, light emitting section 8 may be disposed on the back surface side of light transmitting section 5. In this case, the mirror system 10 includes the mirror 1A and the light emitting unit 8.

The light Emitting section 8 includes a light Emitting element such as an led (light Emitting diode), and can switch between a lighting state in which the light Emitting element emits visible light and a lighting-off state in which the light Emitting element is turned off. When the light emitting portion 8 is turned on, the visible light passing through the light transmitting portion 5 (through hole 51A) can be seen from the front surface side of the mirror 1A, and the user can recognize a certain display or illumination. For example, when a display device that displays a message, the current time, and the like by the light emission of the segment LEDs is used as the light emitting unit 8, the light transmitting unit 5 functions as a display surface on which the message, the current time, and the like are displayed. When an illumination device that irradiates visible light to the front surface side of the mirror 1A by light emission of an LED is used as the light emitting section 8, the light transmitting section 5 functions as a light emitting surface. The light emitting unit 8 may be a device other than a display device or an illumination device.

In this case, the viewing angle of the light emitting unit 8 is determined by the range of the travel angle θ of the light that can pass through the light transmitting portion 5 (through hole 51A). Therefore, in order to widen the viewing angle of the light emitting section 8, it is effective to widen the range of the traveling angle of the light that can pass through the light transmitting section 5 (the through hole 51A).

Therefore, in the through-hole 51A of the present embodiment, if the cross-sectional area of the through-hole 51A is increased in stages from the 1 st opening 511 to the 2 nd opening 512. Therefore, as in the case of the light receiving unit 7 described above, the range of the travel angle θ of the light that can pass through the through hole 51A is wider than the range of the travel angle θ of the light that can pass through the through hole 200, and the viewing angle of the light emitting unit 8 is also widened.

As described above, in the mirror 1A of the present embodiment, the range of the travel angle θ of light that can pass through the through-hole 51A formed in the thickness direction in the reflective film 3 and the protective film 4 can be made wider than in the comparative example. As a result, in the mirror system 10, the detection angle of the light receiving unit 7 and the viewing angle of the light emitting unit 8 are widened.

In the mirror system 10, a reflective human detection sensor including both the light receiving unit 7 and the light emitting unit 8 may be disposed on the rear surface side of the light transmitting unit 5. In this case, the infrared light emitted from the light emitting section 8 is irradiated to the front of the mirror 1A through the opening 1, and the infrared light reflected by the user existing in front of the mirror 1A passes through the opening 1 511 and is received by the light receiving section 7. The reflective human detection sensor detects the presence of a user based on infrared light received by the light receiving unit 7. In this configuration, the same effects as described above can be obtained.

The number of the through holes 51A provided in the light transmitting portion 5 is not limited to 1, and the light transmitting portion 5 may include 2 or more through holes 51A for transmitting light.

Next, fig. 11B shows an 8 th modification of the through hole 51A of the light transmitting portion 5.

The through hole 51A of fig. 11B includes a 1 st space 61A and a 2 nd space 62A, the 1 st space 61A is formed in a cylindrical shape extending from the front surface 31 of the reflective film 3 to the inside of the protective film 4, an end of the 1 st space 61A is a 1 st opening 511, another end of the 1 st space 61A enters the protective film 4 and is located closer to the rear surface 42 than the front surface 41 of the protective film 4, the 2 nd space 62A is formed in a cylindrical shape extending between another end of the 1 st space 61A entering the protective film 4 and the rear surface 42 of the protective film 4, an end of the 2 nd space 62A is a 2 nd opening 512, and another end of the 2 nd space 62A is connected to another end of the 1 st space 61A.

The step 513 as the boundary between the 1 st space 61A and the 2 nd space 62A is located closer to the front surface 41 than the back surface 42 of the protective film 4, and the protective film 4 constituting the bottom surface of the 2 nd space 62A is formed to have a film thickness enough to protect the back surface 32 of the reflective film 3. That is, in the 8 th modification example, the protective film 4 is provided on the bottom surface of the 2 nd space 62A, and the rear surface 32 of the reflective film 3 is not exposed in the through hole 51A, so that the reflective film 3 can be protected.

In the through-hole 51A of the 8 th modification example, if the through-hole is close to the 2 nd opening 512 from the 1 st opening 511, the cross-sectional area of the through-hole 51A becomes large in stages at the stepped portion 513, and the range of the traveling angle θ of the light that can pass through the through-hole 51A can be made wider than that of the comparative example. As a result, in the mirror system 10, the detection angle of the light receiving unit 7 and the viewing angle of the light emitting unit 8 become wider.

Next, fig. 14A shows a 9 th modification of the through hole 51A of the light transmitting portion 5.

The through hole 51A of fig. 14A includes a 1 st space 61B and a 2 nd space 62B, the 1 st space 61B is formed in a cylindrical shape penetrating between the front surface 31 and the back surface 32 of the reflective film 3, an end of the 1 st space 61B is a 1 st opening 511, the 2 nd space 62B is formed in a truncated conical shape penetrating between the front surface 41 and the back surface 42 of the protective film 4, a end of the 2 nd space 62B is a 2 nd opening 512, a diameter (area) of the 2 nd opening 512 is larger than a diameter (area) of the 1 st opening 511, a tapered surface 514 is formed in the protective film 4, and a diameter of the through hole 51A continuously changes in the protective film 4.

That is, in the 9 th modification example, the 2 nd space 62B is formed in a truncated cone shape, and the rear surface 32 of the reflective film 3 is not exposed in the through hole 51A, so that the reflective film 3 can be protected.

In the through-hole 51A of the 9 th modification example, if the through-hole 51A is close to the 2 nd opening 512 from the 1 st opening 511, the cross-sectional area of the through-hole 51A is continuously increased in the protective film 4, and the range of the traveling angle θ of the light that can pass through the through-hole 51A can be made wider than that of the comparative example. As a result, in the mirror system 10, the detection angle of the light receiving unit 7 and the viewing angle of the light emitting unit 8 become wider.

Next, fig. 14B shows a 10 th modification of the through hole 51A of the light transmitting portion 5.

The through hole 51A in fig. 14B includes a 1 st space 61C and a 2 nd space 62C, the 1 st space 61C is formed in a cylindrical shape extending from the front surface 31 of the reflective film 3 to the inside of the protective film 4, an end of the 1 st space 61C is a 1 st opening 511, another end of the 1 st space 61C enters the protective film 4 and is located closer to the back surface 42 than the front surface 41 of the protective film 4, the 2 nd space 62C is formed in a truncated cone shape passing through between another end of the 1 st space 61C entering the protective film 4 and the back surface 42 of the protective film 4, an end of the 2 nd space 62C is a 2 nd opening 512, and another end of the 2 nd space 62C is connected to another end of the 1 st space 61C.

The boundary between the 1 st space 61C and the 2 nd space 62C is located closer to the front surface 41 than the rear surface 42 of the protective film 4, and the rear surface 32 of the reflective film 3 is protected by the protective film 4 having a sufficient thickness.

In the through-hole 51A of the 10 th modification example, if the through-hole 51A is close to the 2 nd opening 512 from the 1 st opening 511, the cross-sectional area of the through-hole 51A is continuously increased in the protective film 4, and the range of the traveling angle θ of the light that can pass through the through-hole 51A can be made wider than that of the comparative example. As a result, in the mirror system 10, the detection angle of the light receiving unit 7 and the viewing angle of the light emitting unit 8 become wider.

In the above-described embodiment and modifications, the cross-sectional shape of the through-hole 51A is not limited to a circular shape, and may be other shapes such as a regular polygon shape, an elliptical shape, and a rectangular shape. That is, the 1 st spaces 61, 61A, 61B, 61C and the 2 nd spaces 62, 62A, 62B, 62C may have a regular polygonal column shape, a regular polygonal frustum shape, an elliptical column shape, an elliptical truncated cone shape, a rectangular frustum shape, or the like. Further, the cross-sectional shape of the 1 st space and the cross-sectional shape of the 2 nd space constituting the through-hole 51A may be different from each other.

For example, in the case where the cross-sectional shape of the through-hole 51A is a rectangular shape, the shorter dimension of the rectangular 2 nd opening is longer than the shorter dimension of the rectangular 1 st opening, whereby the range of the travel angle θ of the light that can pass through the through-hole 51A in the shorter direction can be made wider than that of the comparative example.

In addition, when the protective film 4 is left on the rear surface 32 so that the rear surface 32 of the reflective film 3 is not exposed in the through hole 51A, the embodiment other than the above-described 8 th to 10 th modified examples may be adopted. That is, the portion of the protective film 4 inside the through hole 51A having the same thickness as the portion of the protective film 4 outside the through hole 51A may be located outside the peripheral edge of the 1 st opening 511 in the front view.

Next, fig. 15A and 15B show an 11 th modification of the light transmitting portion 5, in fig. 15A, a plurality of fine through holes 51A are arranged in a rectangular shape, and the light transmitting portion 5 is formed in a rectangular shape, in addition, fig. 15A is a front view showing a portion of the reflection film 3 including the light transmitting portion 5, and fig. 15B is a front view showing a portion area 50 (see fig. 15A) of the light transmitting portion 5, in fig. 15A and 15B, the plurality of through holes 51A are regularly arranged in a lattice shape, and a predetermined number of through holes 51A arranged in rows in the left-right direction constitute 1 row, and the plurality of rows are arranged in the up-down direction.

In the light transmitting portion 5 of the 11 th modification, a plurality of fine through holes 51A are discretely arranged. In this case, the width L1 of the 1 st opening 511 of the through hole 51A is set to be in the range of 0.01[ mm ] to 1[ mm ]. In fig. 15A and 15B, the cross-sectional shape of the through hole 51A is circular, and the diameter of the circular 1 st opening 511 corresponds to the width L1. Therefore, the diameter of the 1 st opening 511 is set in the range of 0.01[ mm ] to 1[ mm ]. The diameter of the circular 2 nd opening 512 is set to be larger than the diameter of the 1 st opening 511.

When the cross-sectional shape of the through-hole 51A is an ellipse, the minor diameter of the elliptical 1 st opening 511 corresponds to the width L1. The minor axis of the elliptical 2 nd aperture 512 is set to be larger than the minor axis of the 1 st aperture 511.

When the cross-sectional shape of the through-hole 51A is rectangular, the dimension of the 1 st rectangular opening 511 in the shorter direction corresponds to the width dimension L1. The dimension of the rectangular 2 nd opening 512 in the shorter direction is set to a value larger than the dimension of the 1 st opening 511 in the shorter direction.

When the cross-sectional shape of the through-hole 51A is a regular polygon, the diameter of a circle (circumscribed circle) circumscribing the 1 st opening 511 of the regular polygon corresponds to the width dimension L1. The diameter of the circumscribed circle of the 2 nd opening 512 of the regular polygon is set to a value larger than the diameter of the circumscribed circle of the 1 st opening 511.

Furthermore, each of the 1 st openings 511 is disposed on the surface 31 of the reflective film 3 so that the distance W from the adjacent 1 st opening 511 is 0.01[ mm ] to 2[ mm ]. That is, the distance W of the adjacent 21 st openings 511 among the plurality of 1 st openings 511 is included in the range of 0.01[ mm ] or more and 2[ mm ] or less, and the density of the 1 st openings 511 on the surface 31 is determined by the distance W.

Since the through-holes 51A of the 11 th modification are fine, the amount of light passing through 1 through-hole 51A is relatively small. However, the light transmitting portion 5 includes a large number of through holes 51A. That is, the density of the 1 st openings 511 on the front surface 31 of the reflective film 3 and the density of the 2 nd openings 512 on the back surface 42 of the protective film 4 are set so that a sufficient amount of light reaches the light receiving section 7 and light emitted from the light emitting section 8 is irradiated in front of the mirror 1A with a sufficient amount of light.

When the light emitting section 8 is turned off, the light of the light emitting section 8 is not emitted from the 1 st opening 511. The width L1 of the 1 st opening 511 is set to a value at which the 1 st opening 511 is less likely to be noticeable when viewed from the user. Therefore, the 1 st opening 511 which does not emit light has a minute size in the surface 31 of the reflective film 3 to such an extent that it is difficult to recognize by a user present on the surface side of the mirror 1A. As a result, the light transmitting portion 5 (the plurality of 1 st openings 511) becomes inconspicuous in the surface 31 of the reflective film 3, and the function as a mirror surface of the light transmitting portion 5 becomes substantially equivalent to the surface 31 of the reflective film 3 where the light transmitting portion 5 is not formed.

As described above, the light transmitting portion 5 of the 11 th modification includes the plurality of through holes 51A (the plurality of silver removing portions) for removing the reflective film 3 and the protective film 4 in the front view, and the plurality of through holes 51A are arranged discretely. As a result, the light transmitting portion 5 functions as a pseudo half mirror, is less conspicuous, and has high hiding performance and high design performance. That is, the mirror 1A according to the 11 th modification can make the light transmitting portion 5 having light transmittance less conspicuous and ensure the function of the light transmitting portion 5 as a mirror surface.

Further, since the mirror 1A of modification 11 functions as a natural mirror surface, the light transmitting portion 5 can be provided, and the mirror can be used for makeup and the like while suppressing a decrease in the main quality (color tone, brightness, shape, and the like of a virtual image) of the mirror.

In the mirror 1A according to the 11 th modification described above, in order to ensure recessive shielding of the light transmission portion 5, the size of the 1 st opening 511 (for example, the width L1 or the like) needs to be reduced. Further, the smaller the size of the 1 st opening 511 is, the more the recessing property of the light transmitting portion 5 is improved. However, since the film thickness dimension Ha with respect to the dimension of the 1 st opening 511 is relatively larger as the dimension of the 1 st opening 511 is smaller, there is a trade-off between narrowing the detection angle of the light receiving unit 7 and the viewing angle of the light emitting unit 8 by the protective film 4.

Therefore, as in any of embodiment 2 and 8 th to 10 th modifications described above, by removing the protective film 4 from each of the plurality of 1 st openings 511 so that the area of the 2 nd opening 512 is larger than the area of the 1 st opening 511, it is possible to secure a wide detection angle and a wide viewing angle while securing the recessed property of the light transmitting portion 5.

The plurality of through holes 51A in the translucent portion 5 may be irregularly arranged.

Further, if the area of the 2 nd opening 512 is increased, the 2 nd openings 512 adjacent to each other are joined to each other on the back surface 42 of the protective film 4, and as a result, 1 opening may be formed by the plurality of 2 nd openings 512. In this case, since the 1 opening formed in the back surface 42 of the protective film 4 provides the same operation and effect as the plurality of 2 nd openings 512, the same effect as described above can be obtained.

Further, it is also preferable to apply any of embodiment 2 and 8 th to 10 th modifications to embodiment 1 and 1 st to 7 th modifications described above. In this case, the protective film 4 is removed from each of the plurality of 1 st openings 511, 521, 531, 541, and the area of the 2 nd opening 512 is larger than the area of each of the 1 st openings 511, 521, 531, 541. As a result, the recessed property of the light transmitting portion 5 can be ensured, and a wide detection angle and a wide viewing angle can be ensured.

Next, fig. 16 shows a 12 th modification of the structure of the through hole 51A.

In the above-described embodiment, the light-transmitting through-hole 51A is hollow inside, and the end surface (edge) of the reflective film 3 is exposed on the side surface of the through-hole 51A, so that there is a possibility that rust or the like may occur on the end surface of the reflective film 3 to cause corrosion. Therefore, as shown in fig. 16, it is preferable to form a light-transmitting protective film 9 on the rear surface 42 side of the protective film 4 and fill the light-transmitting protective film 9 in the through hole 51A. In this case, the through hole 51A is filled with the light-transmitting protective film 9, and the cavity inside the through hole 51A can be eliminated to discharge air. Therefore, the end face of the reflective film 3 is covered with the protective film 9, and therefore, the occurrence of corrosion of the reflective film 3 can be suppressed. The light-transmitting protective film 9 can be applied to embodiments 1 and 2 and 1 st to 11 th modifications, respectively.

As a method of forming the through hole 51A for light transmission in the mirror 1A, a method of forming the reflection film 3 and the protection film 4 in a portion to be the through hole 51A in a manufacturing process of forming the reflection film 3 and the protection film 4 on the glass substrate 2 may be employed. As such a method, for example, a masking method may be employed in which a portion to be the through hole 51A is masked so that the reflective film 3 and the protective film 4 are not formed when the reflective film 3 and the protective film 4 are formed on the glass substrate 2. For example, when the reflective film 3 is formed on the glass substrate 2, the portions to be the 1 st spaces 61, 61A, 61B, and 61C are masked so that the reflective film 3 is not formed. When the protective film 4 is formed on the reflective film 3, the portions to be the 2 nd spaces 62, 62A, 62B, and 62C are masked so that the protective film 4 is not formed.

When the masking method is used, the back surface 22 of the glass substrate 2 facing the through-hole 51A is easily made flat without roughness. In the case of adopting the method in which the reflective film 3 and the protective film 4 are not formed at the portion to be the through hole 51A as described above, the step of forming the mirror 1A includes a step of forming the through hole 51A.

After the reflective film 3 and the protective film 4 are formed on the glass substrate 2, the through-hole 51A may be formed by laser processing, jet processing, etching processing, machining (processing by a cutting edge, a grinding edge, or the like), or the like. In this case, the 1 st spaces 61, 61A, 61B, 61C and the 2 nd spaces 62, 62A, 62B, 62C are formed by laser processing, spray processing, etching processing, machining processing, or the like. In this method, since the through-hole 51A can be formed by applying laser processing, spray processing, etching processing, machining processing, or the like to a commercially available mirror, the manufacturing cost of the mirror 1A can be suppressed.

For example, in the case of laser processing, laser light is irradiated from the front surface 21 side of the glass substrate 2. The laser light passes through the glass substrate 2 to heat the reflective film 3 and the protective film 4, and the heated reflective film 3 and protective film 4 are evaporated. In addition, when the etching process is performed, the back surface 42 of the protective film 4 is subjected to a masking treatment.

In addition, since the step 513 or the tapered surface 514 may be formed only on the protective film 4 on the side surface of the through hole 51A when forming the through hole 51A, the through hole 51A can be formed more easily than when processing both the reflective film 3 and the protective film 4.

As described above, the mirror 1A according to embodiment 10 has the 1 st opening 511 formed as the opening of the through hole 51A on the front surface 31 of the reflective film 3, and the 2 nd opening 512 of the through hole 51A is formed on the rear surface 42 of the protective film 4, with respect to 1 of the 1 st to 9 th aspects, and the area of the 2 nd opening 512 is larger than the area of the 1 st opening 511.

The mirror 1A described above can widen the range of the travel angle θ of light that can pass through the through-hole 51A formed in the thickness direction in the reflective film 3 and the protective film 4, compared to the comparative example. As a result, in the mirror system 10, the detection angle of the light receiving unit 7 and the viewing angle of the light emitting unit 8 become wider.

In the mirror 1A according to embodiment 11, in embodiment 10, it is preferable that the through hole 51A has a sectional area orthogonal to the thickness direction that increases stepwise or continuously in the protective film 4 as it approaches the 2 nd opening 512.

Since the above-described mirror 1A only needs to form the step 513 or the tapered surface 514 in the protective film 4, the through hole 51A can be formed more easily than the case where both the reflective film 3 and the protective film 4 are processed.

In the mirror 1A according to embodiment 12, in embodiment 11, the through hole 51A preferably includes a columnar 1 st space 61 formed in the reflective film 3 and a columnar 2 nd space 62 formed in the protective film 4, and the cross-sectional area of the 2 nd space 62 is larger than the cross-sectional area of the 1 st space 61.

The mirror 1A described above can widen the range of the traveling angle θ of the light that can pass through the through hole 51A as much as possible.

In the mirror 1A according to embodiment 13, in embodiment 11, the through hole 51A preferably includes a 1 st cylindrical space 61A extending from the front surface 31 of the reflective film 3 to the inside of the protective film 4 and a 2 nd cylindrical space 62A extending from the inside of the protective film 4 to the back surface 42 of the protective film 4. The cross-sectional area of the 2 nd space 62A is larger than the cross-sectional area of the 1 st space 61A.

Since the protective film 4 is provided on the bottom surface of the 2 nd space 62A of the mirror 1A and the rear surface 32 of the reflective film 3 is not exposed in the through hole 51A, the reflective film 3 can be protected.

In the mirror 1A according to embodiment 14, in embodiment 11, the through hole 51A preferably includes a columnar 1 st space 61B formed in the reflective film 3 and a truncated 2 nd space 62B formed in the protective film 4. The sectional area of the 2 nd space 62B is continuously increased as it approaches the 2 nd opening 512, and the sectional area of the 2 nd space 62B is equal to or larger than the sectional area of the 1 st space 61B.

Since the 2 nd space 62B of the mirror 1A is formed in a truncated cone shape and the rear surface 32 of the reflective film 3 is not exposed in the through hole 51A, the reflective film 3 can be protected.

In the mirror 1A according to embodiment 15, in embodiment 11, the through hole 51A preferably includes a 1 st cylindrical space 61C extending from the front surface 31 of the reflective film 3 to the inside of the protective film 4 and a 2 nd truncated conical space 62C extending from the inside of the protective film 4 to the back surface 42 of the protective film 4. The sectional area of the 2 nd space 62C is continuously increased as it approaches the 2 nd opening 512, and the sectional area of the 2 nd space 62C is equal to or larger than the sectional area of the 1 st space 61C.

The mirror 1A can protect the rear surface 32 of the reflective film 3 with the protective film 4 having a sufficient thickness.

In the mirror 1A according to embodiment 16, it is preferable that any of the 10 th to 15 th aspects further include a light-transmissive protective film 9 filled in the through hole 51A.

Since the end face of the reflective film 3 of the mirror 1A is covered with the protective film 9, the occurrence of corrosion of the reflective film 3 can be suppressed.

In the mirror 1A according to the 17 th aspect of the embodiment, in any of the 10 th to 16 th aspects, it is preferable that the 1 or more through holes 51A be a plurality of through holes 51A, that the 1 st opening 511 of each of the plurality of through holes 51A be formed in the surface 31 of the reflective film 3, and that the width dimension L1 of the plurality of 1 st openings 511 in the direction along the surface 31 of the reflective film 3 be set to be in a range of 0.01[ mm ] or more and 1[ mm ] or less, respectively.

In the mirror 1A, the plurality of through holes 51A (1 st opening 511) are discretely arranged. As a result, the plurality of through holes 51A function as an analog half mirror, are less noticeable, and have high recessive properties. That is, the mirror 1A can ensure light transmittance of the plurality of through holes 51A, and can ensure a function as a mirror surface by making the plurality of through holes 51A less noticeable.

In addition, in the mirror 1A according to the 18 th aspect of the embodiment, in the 17 th aspect, it is preferable that the separation distance W of the adjacent 21 st openings 511 among the plurality of 1 st openings 511 is set to be in the range of 0.01[ mm ] or more and 2[ mm ] or less.

In the above-described mirror 1A, the total light amount of light passing through the plurality of through holes 51A can be sufficiently ensured while securing the recessive ability of the plurality of through holes 51A.

In the mirror 1A according to the 19 th aspect of the present embodiment, in the 17 th or 18 th aspect, it is preferable that the 2 nd openings 512 of the through holes 51A are connected to each other to form 1 opening.

Since the mirror 1A includes 1 opening formed by connecting the plurality of 2 nd openings 512 on the back surface, the detection angle of the light receiving unit 7 and the viewing angle of the light emitting unit 8 can be further increased by .

The mirror system 10 according to embodiment 20 includes any mirrors 1A of the above-described 10 th to 19 th aspects, and the light receiving unit 7 provided on the rear surface 42 side of the protective film 4 so as to face the 2 nd opening 512, and the light receiving unit 7 receives light incident into the 1 st opening 511 and emitted from the 2 nd opening 512.

In the mirror system 10 described above, the detection angle of the light receiving section 7 becomes wider.

The mirror system 10 according to embodiment 21 includes any mirrors 1A of the above-described 10 th to 19 th aspects, and a light emitting unit 8 that is provided on the rear surface 42 side of the protective film 4 so as to face the 2 nd opening 512 and emits light, and light emitted by the light emitting unit 8 enters the 2 nd opening 512 and exits from the 1 st opening 511.

In the mirror system 10 described above, the viewing angle of the light emitting unit 8 becomes wider.

The above-described embodiments and modifications are of the present invention, and therefore the present invention is not limited to the above-described embodiments and modifications, and various modifications can be made without departing from the scope of the technical idea of the present invention in addition to the embodiments and modifications, as long as the modifications do not depart from the scope of the technical idea of the present invention.
