Description

この発明は、紫外線照射量を測定する紫外線測定装置、該紫外線測定装置を備えたコンパクトケースおよび電子機器に関するものである。   The present invention relates to an ultraviolet ray measuring device for measuring an ultraviolet ray irradiation amount, a compact case provided with the ultraviolet ray measuring device, and an electronic apparatus.

従来、ＵＶ（紫外線）センサを内蔵した各種の製品が市場に存在する。例えば、屋外に持ち運び単純にＵＶ量を測定するだけ装置や、携帯電話機に内蔵されたもの等が存在する。   Conventionally, various products with a built-in UV (ultraviolet) sensor exist on the market. For example, there are devices that can be carried outdoors and simply measure the amount of UV, and those built into mobile phones.

このような各種製品に内蔵されているＵＶセンサは、紫外線のみに対して十分な感度を有する素子が殆ど無く、一般的にＳｉフォトダイオードやＧａＡｓＰダイオードのように可視光を含む幅広い周波数帯域に対して所定の感度を有する可視光検出素子を用いている。   The UV sensors incorporated in such various products have few elements that have sufficient sensitivity to only ultraviolet rays, and generally have a wide frequency range including visible light, such as Si photodiodes and GaAsP diodes. Thus, a visible light detecting element having a predetermined sensitivity is used.

このため、従来の紫外線測定装置では、特許文献１に示すように、当該可視光検出素子とともに、紫外線通過フィルタ、および、紫外線を可視光に周波数変換する蛍光体を備える。この際、図６に示すように、可視光検出素子１、蛍光体２、紫外線通過フィルタ３が配置される。図６は、従来の紫外線測定装置１００の主要構成を示す断面図である。   For this reason, as shown in Patent Document 1, a conventional ultraviolet ray measuring apparatus includes an ultraviolet light passing filter and a phosphor that converts the frequency of ultraviolet light into visible light together with the visible light detection element. At this time, as shown in FIG. 6, the visible light detecting element 1, the phosphor 2, and the ultraviolet light passing filter 3 are arranged. FIG. 6 is a cross-sectional view showing the main configuration of a conventional ultraviolet ray measuring apparatus 100.

図６に示すように、可視光検出素子１は、携帯電話機等の実装回路基板９００に実装された信号処理回路基板９０上に実装されている。この際、可視光検出素子１は、受波面１１が筐体１１０の開口部１０１により開口される領域内となるように配置されている。   As shown in FIG. 6, the visible light detection element 1 is mounted on a signal processing circuit board 90 mounted on a mounting circuit board 900 such as a mobile phone. At this time, the visible light detection element 1 is arranged so that the wave receiving surface 11 is in a region opened by the opening 101 of the housing 110.

このような構成において、蛍光体２は可視光検出素子１の受波面１１側に設置され、紫外線通過フィルタ３は、当該蛍光体２の可視光検出素子１と反対側に設置される。   In such a configuration, the phosphor 2 is disposed on the wave receiving surface 11 side of the visible light detection element 1, and the ultraviolet light passing filter 3 is disposed on the opposite side of the phosphor 2 from the visible light detection element 1.

さらに、このような構成の紫外線測定装置１００では、可視光検出素子１や信号処理回路基板９０上の各回路素子等を外部からの塵や埃等から保護するために、開口部１０１にカバー部材４が設置されている。
特公平５−３５９７６号公報 Further, in the ultraviolet ray measuring apparatus 100 having such a configuration, in order to protect the visible light detection element 1 and each circuit element on the signal processing circuit board 90 from dust and dirt from the outside, a cover member is provided in the opening 101. 4 is installed.
Japanese Patent Publication No. 5-35976

しかしながら、図６に示したような従来の紫外線測定装置１００では、紫外線の測定機能に直接関係しない保護用のカバー部材４を必要とする。このため、紫外線測定装置１００を構成する構成部品数が多くなってしまう。また、カバー部材４は、筐体１１０内に光を透過させなければならないので、透明な素材や半透明な素材で形成しなければならない。このため、外部から当該開口部１０１を見ると紫外線通過フィルタ３、蛍光体２、可視光検出素子１はもとより、信号処理回路基板９０や実装回路基板９００まで見えてしまい、デザイン性を損なってしまう。   However, the conventional ultraviolet ray measuring apparatus 100 as shown in FIG. 6 requires a protective cover member 4 that is not directly related to the ultraviolet ray measuring function. For this reason, the number of components constituting the ultraviolet ray measuring apparatus 100 increases. Further, since the cover member 4 has to transmit light into the housing 110, the cover member 4 must be formed of a transparent material or a translucent material. For this reason, when the opening 101 is viewed from the outside, not only the ultraviolet light passing filter 3, the phosphor 2, and the visible light detection element 1 but also the signal processing circuit board 90 and the mounting circuit board 900 are visible, and the design is impaired. .

本発明の目的は、デザイン性を損なうことなく且つ紫外線測定性能を不要に低下させることのない簡素な構造の紫外線測定装置を実現することにある。   An object of the present invention is to realize an ultraviolet measuring device having a simple structure without impairing the design and without unnecessarily degrading the ultraviolet measuring performance.

この発明は、紫外線に感応する紫外線感応素子と、紫外線感応素子を覆うカバー部材と、を備えた紫外線測定装置に関するものである。この紫外線測定装置のカバー部材は、透光性を有する保護層と、紫外線を透過するとともに可視光を反射する周波数選択層とを備えている。   The present invention relates to an ultraviolet ray measuring device including an ultraviolet ray sensitive element sensitive to ultraviolet rays and a cover member covering the ultraviolet sensitive element. The cover member of the ultraviolet ray measuring apparatus includes a protective layer having translucency and a frequency selection layer that transmits ultraviolet rays and reflects visible light.

この構成では、カバー部材が、紫外線感応素子（ＵＶセンサ）を外部環境から保護する機能を有するとともに、紫外線感応素子へ紫外線のみを照射させる。すなわち、カバー部材で可視光が反射されるので、当該カバー部材における紫外線感応素子と対向する側からは、紫外線感応素子が見えなくなるが、紫外線は紫外線感応素子で受波される。   In this configuration, the cover member has a function of protecting the ultraviolet sensitive element (UV sensor) from the external environment and irradiates only the ultraviolet sensitive element to the ultraviolet sensitive element. That is, since visible light is reflected by the cover member, the ultraviolet sensitive element becomes invisible from the side of the cover member facing the ultraviolet sensitive element, but the ultraviolet light is received by the ultraviolet sensitive element.

また、この発明の紫外線測定装置では、保護層はガラス基板であり、周波数選択層はガラス基板の少なくとも一面に形成された銀薄膜である。   In the ultraviolet ray measuring apparatus of the present invention, the protective layer is a glass substrate, and the frequency selective layer is a silver thin film formed on at least one surface of the glass substrate.

この構成では、具体的にカバー部材は、ガラス基板と該ガラス基板に蒸着等により形成された銀（Ａｇ）薄膜とからなる。ここで、銀は図７に示す反射特性を有する。図７は銀（Ａｇ）および金（Ａｕ）、銅（Ｃｕ）の反射特性を示す特性図である。この図７に示すように、銀は、紫外線より長波長である可視光等を略全反射し、紫外線を透過する性質を有する。このように、銀が可視光を反射して紫外線を透過するので、当該構成を用いれば、紫外線感応素子を外部から見えなくしながら、紫外線感応素子へ紫外線のみを確実に照射させることができる。   In this configuration, the cover member specifically includes a glass substrate and a silver (Ag) thin film formed on the glass substrate by vapor deposition or the like. Here, silver has the reflection characteristics shown in FIG. FIG. 7 is a characteristic diagram showing the reflection characteristics of silver (Ag), gold (Au), and copper (Cu). As shown in FIG. 7, silver has the property of substantially totally reflecting visible light having a longer wavelength than ultraviolet rays and transmitting ultraviolet rays. Thus, since silver reflects visible light and permeate | transmits an ultraviolet-ray, if the said structure is used, it can irradiate only an ultraviolet-ray to an ultraviolet-sensitive element, making an ultraviolet-sensitive element invisible from the outside.

また、この発明の紫外線測定装置では、周波数選択層である銀は、保護層の紫外線感応素子側にのみ形成されている。   In the ultraviolet ray measuring apparatus of the present invention, the silver as the frequency selective layer is formed only on the ultraviolet sensitive element side of the protective layer.

この構成では、カバー部材は、使用者側から順にガラス基板、銀の順で層状化されることとなり、一般的な銀鏡と同様な構造を用いることができる。これにより、カバー部材を容易に形成することができる。さらに、このカバー部材の部分を、まさに鏡として利用することもできる。   In this configuration, the cover member is layered in the order of the glass substrate and silver in order from the user side, and a structure similar to a general silver mirror can be used. Thereby, a cover member can be formed easily. Further, the cover member portion can be used as a mirror.

また、この発明の紫外線測定装置の紫外線感応素子は、可視光に対しても感応するダイオードまたはフォトダイオードからなる。   Further, the ultraviolet sensitive element of the ultraviolet measuring device of the present invention comprises a diode or a photodiode sensitive to visible light.

この構成では、特殊な受波特性を有する紫外線感応素子を用いることなく、一般的に用いられているダイオードやフォトダイオードを用いても、紫外線感応素子で確実に紫外線のみを受波することができる。   With this configuration, it is possible to reliably receive only ultraviolet rays with a UV sensitive element without using a UV sensitive element with special wave receiving characteristics, even with a commonly used diode or photodiode. it can.

また、この発明の紫外線測定装置は、紫外線感応素子を内装し、該紫外線感応素子に対して外部から光を照射させるための開口部を備えた筐体を備える。そして、カバー部材は、開口部の開口面を完全に覆うように設置されている。   In addition, the ultraviolet ray measuring apparatus of the present invention includes a housing having an ultraviolet sensitive element and an opening for irradiating the ultraviolet sensitive element with light from the outside. And the cover member is installed so that the opening surface of an opening part may be covered completely.

この構成では、カバー部材が紫外線感応素子を内装する筐体の開口部に形成されているので、筐体外部の環境から紫外線感応素子を保護することができるとともに、外部から紫外線感応素子等を見えなくすることができる。この際、紫外線は、確実に紫外線感応素子へ伝搬される。   In this configuration, since the cover member is formed at the opening of the housing that houses the ultraviolet sensitive element, the ultraviolet sensitive element can be protected from the environment outside the housing, and the ultraviolet sensitive element and the like can be seen from the outside. Can be eliminated. At this time, the ultraviolet rays are reliably transmitted to the ultraviolet sensitive element.

また、この発明の紫外線測定装置は、筐体内に、カバー部材を透過した紫外線を紫外線感応素子の受波面に集光する集光部材を備えている。   The ultraviolet ray measuring apparatus according to the present invention further includes a condensing member for condensing the ultraviolet ray transmitted through the cover member on the wave receiving surface of the ultraviolet sensitive element.

この構成では、カバー部材を透過した紫外線が集光部材により紫外線感応素子へ集められるので、高感度な紫外線測定装置を実現することができる。   In this configuration, since the ultraviolet light transmitted through the cover member is collected by the light collecting member to the ultraviolet sensitive element, a highly sensitive ultraviolet measuring device can be realized.

また、この発明のコンパクトケースは、上述の紫外線測定装置を備える。このコンパクトケースは、紫外線感応素子による紫外線の受波量に応じた紫外線検出信号を出力する信号処理回路と、該紫外線検出信号のレベルに応じた通知を外部へ行う通知部と、紫外線感応素子、前記信号処理回路および通知部に対して電力供給を行う電源部とが筐体に設置されている。そして、このコンパクトケースでは、カバー部材が鏡部となる。   Moreover, the compact case of this invention is equipped with the above-mentioned ultraviolet measuring device. The compact case includes a signal processing circuit that outputs an ultraviolet detection signal according to the amount of received ultraviolet light by the ultraviolet sensitive element, a notification unit that performs notification according to the level of the ultraviolet detection signal, an ultraviolet sensitive element, A power supply unit that supplies power to the signal processing circuit and the notification unit is installed in the housing. And in this compact case, a cover member becomes a mirror part.

この構成では、コンパクトケースに元々備えられている鏡を紫外線測定装置のカバー部材に兼用し、コンパクトケース内に紫外線感応素子等を収納することで、外観的な付加やデザイン性を低下させることなく、単なるコンパクトケースとして利用するだけでなく、紫外線測定装置としても利用することができる。この際、測定した紫外線量に応じて通知部から紫外線照射情報を提供できるようにすることで、紫外線量に応じた化粧品（例えば、カバー力強化指数の異なる化粧品等）の選択情報も提供できる。   In this configuration, the mirror originally provided in the compact case is also used as the cover member of the ultraviolet ray measuring device, and the ultraviolet sensitive element and the like are housed in the compact case, so that the appearance and design are not deteriorated. It can be used not only as a simple case but also as an ultraviolet ray measuring device. At this time, by making it possible to provide ultraviolet irradiation information from the notification unit according to the measured amount of ultraviolet rays, it is also possible to provide selection information for cosmetics (for example, cosmetics with different covering power enhancement indexes) according to the amount of ultraviolet rays.

また、この発明の電子機器は、上述の紫外線測定装置を備える。この電子機器は、紫外線感応素子による紫外線の受波量に応じた紫外線検出信号を出力する信号処理回路と、該紫外線検出信号のレベルに応じた通知を行う外部へ行う通知部と、紫外線感応素子、信号処理回路および通知部に対して電力供給を行う電源部とが筐体に設置されている。   Moreover, the electronic device of this invention is equipped with the above-mentioned ultraviolet ray measuring apparatus. The electronic apparatus includes a signal processing circuit that outputs an ultraviolet detection signal corresponding to an amount of received ultraviolet rays by the ultraviolet sensitive element, an external notification unit that performs notification according to the level of the ultraviolet detection signal, and an ultraviolet sensitive element. A signal processing circuit and a power supply unit that supplies power to the notification unit are installed in the housing.

この構成では、例えば携帯電話や携帯端末装置のように屋外へ持ち運ぶことがある電子機器に対して、紫外線測定装置を備えさせることで、上述のコンパクトケースと同様にデザイン性を低下させることなく紫外線測定装置として機能させ、紫外線照射情報を提供することができる。この際、これらの電子機器は、バッテリを通常に備えているので、当該バッテリを紫外線測定装置の電源部として利用することができる。また、画素数の多い表示部を利用できるので、より詳細で豊富な紫外線測定結果に応じた情報を容易に提供することができる。   In this configuration, for example, an electronic device that may be carried outdoors, such as a mobile phone or a mobile terminal device, is equipped with an ultraviolet ray measuring device, so that ultraviolet rays can be produced without degrading design as in the above-described compact case. It can function as a measuring device and provide UV irradiation information. At this time, since these electronic devices are normally provided with a battery, the battery can be used as a power supply unit of the ultraviolet ray measuring apparatus. In addition, since a display unit having a large number of pixels can be used, more detailed and abundant information according to the ultraviolet measurement result can be easily provided.

この発明によれば、確実に紫外線のみの照射量を測定する紫外線測定装置を、簡素な構造で実現することができる。さらに、これに伴い、紫外線測定装置や、当該紫外線測定装置が装着されたコンパクトケースや各種電子機器のデザイン性を低下させることなく、紫外線測定機能を実現することができる。   According to the present invention, an ultraviolet ray measuring device that reliably measures the irradiation amount of only ultraviolet rays can be realized with a simple structure. Further, along with this, the ultraviolet ray measuring function can be realized without deteriorating the design of the ultraviolet ray measuring device, the compact case equipped with the ultraviolet ray measuring device, and various electronic devices.

本発明の第１の実施形態に係る紫外線測定装置について図を参照して説明する。
図１（Ａ）は本実施形態の紫外線測定装置の主要構成を示す斜視図であり、筐体を除いた状態を示し、図１（Ｂ）は筐体を含む紫外線測定装置の断面図であり、図１（Ｃ）は紫外線および可視光の透過、反射の状態を示す。 An ultraviolet ray measuring apparatus according to a first embodiment of the present invention will be described with reference to the drawings.
FIG. 1A is a perspective view showing the main configuration of the ultraviolet ray measuring apparatus of the present embodiment, showing a state in which the casing is removed, and FIG. 1B is a cross-sectional view of the ultraviolet ray measuring apparatus including the casing. FIG. 1C shows the state of transmission and reflection of ultraviolet light and visible light.

紫外線測定装置２００は、開口部２０１が形成された筐体２１０を有する。筐体２１０内には、平板形状の誘電体基板からなる信号処理回路基板９０が設置されている。当該信号処理回路基板９０の開口部２０１側の実装面には、ＵＶセンサ（本発明の「紫外線感応素子」に相当する。）１０が実装されており、当該ＵＶセンサ１０は、受波面１１が開口部２０１側に向くように実装されている。信号処理回路基板９０には、ＵＶセンサ１０とともに、信号処理回路素子９３、電池ホルダ９１等が実装されている。信号処理回路素子９３は、信号処理回路基板９０を介してＵＶセンサ１０に接続する。また、電池ホルダ９１は、信号処理回路基板９０を介して、ＵＶセンサ１０および信号処理回路素子９３に接続する。電池ホルダ９１には電池９２が装着され、当該電池９２からＵＶセンサ１０および信号処理回路素子９３に電力が供給される。このような構成により、ＵＶセンサ１０が紫外線を受波すると、ＵＶセンサ１０から受波レベルに応じた検出信号が信号処理回路素子９３へ出力される。信号処理回路素子９３は、ＵＶセンサ１０からの検出信号に対して増幅処理等の信号処理を行うことで、紫外線測定装置２００として所望とする信号を出力する。この出力信号は、図示しない紫外線測定結果を解析、表示するモジュール等に供給される。例えば、紫外線測定結果を解析、表示するモジュールであれば、当該モジュールは信号処理回路素子９３からの出力信号を用いて照射紫外線量を算出して表示したり、当該照射紫外線量に基づく注意情報等を表示する。   The ultraviolet ray measuring apparatus 200 includes a housing 210 in which an opening 201 is formed. In the casing 210, a signal processing circuit board 90 made of a flat dielectric substrate is installed. A UV sensor (corresponding to the “ultraviolet sensitive element” of the present invention) 10 is mounted on the mounting surface of the signal processing circuit board 90 on the opening 201 side. The UV sensor 10 has a wave receiving surface 11. It is mounted so as to face the opening 201 side. A signal processing circuit element 93, a battery holder 91, and the like are mounted on the signal processing circuit board 90 together with the UV sensor 10. The signal processing circuit element 93 is connected to the UV sensor 10 via the signal processing circuit board 90. Further, the battery holder 91 is connected to the UV sensor 10 and the signal processing circuit element 93 via the signal processing circuit board 90. A battery 92 is mounted on the battery holder 91, and power is supplied from the battery 92 to the UV sensor 10 and the signal processing circuit element 93. With such a configuration, when the UV sensor 10 receives ultraviolet rays, a detection signal corresponding to the received wave level is output from the UV sensor 10 to the signal processing circuit element 93. The signal processing circuit element 93 outputs a signal desired as the ultraviolet ray measuring apparatus 200 by performing signal processing such as amplification processing on the detection signal from the UV sensor 10. This output signal is supplied to a module or the like for analyzing and displaying an ultraviolet measurement result (not shown). For example, in the case of a module that analyzes and displays an ultraviolet measurement result, the module calculates and displays an irradiation ultraviolet ray amount using an output signal from the signal processing circuit element 93, or displays caution information based on the irradiation ultraviolet ray amount. Is displayed.

このような回路構成を有する本実施形態の紫外線測定装置２００は、次に示す構造的特徴を有する。   The ultraviolet ray measuring apparatus 200 of this embodiment having such a circuit configuration has the following structural features.

筐体２１０の開口部２０１は、ＵＶセンサ１０に受波面１１よりも広い開口面積を有する。開口部２０１には、当該開口部２０１の全面を覆う形状からなるカバー部材４０が設置されている。カバー部材４０は、可視光および紫外線に対する透光性を有するガラス基板４１と、銀薄膜４２との二層構造からなる。カバー部材４０は、銀薄膜４２がＵＶセンサ１０側（筐体２００の内部側）となりガラス基板４１が筐体２００の外部側となるように配置されている。このような構造とすることで、カバー部材４０は銀鏡と同じ機能を有するものとなる。この際、銀薄膜４２は、上述の図７に示したように、可視光は反射するものの紫外線は透過するといった周波数選択性をもった層であるので、筐体２００内に設置されたＵＶセンサ１０には紫外線のみが照射される。これにより、カバー部材４０により、ＵＶセンサ１０を含む筐体２００内部の各種電子部品を外部環境から保護しながら、ＵＶセンサ１０で照射させる紫外線を検出し、且つ、ＵＶセンサ１０を含む筐体２００内部の構造を外部から見えなくすることができる。この結果、デザイン性を低下させることなく、正確に紫外線照射量のみを測定できる紫外線測定装置を実現することができる。   The opening 201 of the housing 210 has an opening area larger than that of the wave receiving surface 11 in the UV sensor 10. The opening 201 is provided with a cover member 40 having a shape that covers the entire surface of the opening 201. The cover member 40 has a two-layer structure of a glass substrate 41 having translucency with respect to visible light and ultraviolet light, and a silver thin film 42. The cover member 40 is disposed such that the silver thin film 42 is on the UV sensor 10 side (inside the housing 200) and the glass substrate 41 is on the outside of the housing 200. With this structure, the cover member 40 has the same function as the silver mirror. At this time, the silver thin film 42 is a layer having a frequency selectivity that reflects visible light but transmits ultraviolet light as shown in FIG. 10 is irradiated only with ultraviolet rays. Accordingly, the cover member 40 detects ultraviolet rays irradiated by the UV sensor 10 while protecting various electronic components inside the casing 200 including the UV sensor 10 from the external environment, and the casing 200 including the UV sensor 10. The internal structure can be made invisible from the outside. As a result, it is possible to realize an ultraviolet ray measuring apparatus capable of accurately measuring only the ultraviolet ray irradiation amount without degrading design.

なお、上述の説明では、ＵＶセンサ１０を用いた例を示したが、カバー部材４０により紫外線のみが筐体２００内に照射されるので、紫外線領域のみでなく可視光領域をも含んで照射量を検出できる広帯域のセンサを用いることもできる。このようなセンサを用いる場合、従来例に示したように、紫外線フィルタが必須構成要件になるが、本実施形態の構成を用いることで、外部環境に対する保護機能と紫外線のみを通過させる周波数選択機能とがカバー部材４０のみで実現できるので、紫外線測定装置の構成部品数を少なくできるとともに、小型化（薄型化）することもできる。   In the above description, an example in which the UV sensor 10 is used is shown. However, since only the ultraviolet rays are irradiated into the housing 200 by the cover member 40, the irradiation amount includes not only the ultraviolet region but also the visible light region. It is also possible to use a wideband sensor that can detect. When using such a sensor, as shown in the conventional example, an ultraviolet filter is an essential component, but by using the configuration of this embodiment, a protection function for the external environment and a frequency selection function that allows only ultraviolet light to pass through. Can be realized only by the cover member 40, the number of components of the ultraviolet ray measuring apparatus can be reduced, and the size (thinning) can be reduced.

また、上述の説明では、信号処理回路基板９０のＵＶセンサ１０実装側に信号処理回路素子９３を実装する例を示したが、当該信号処理回路素子９３は、ＵＶセンサ１０実装側に対する反対側の実装面に実装してもよい。すなわち、ＵＶセンサ１０のみは、信号処理回路基板９０の開口部２０１側に実装しなければならないが、他の電子部品や構成要素は実装面を限定する必要はない。   In the above description, the example in which the signal processing circuit element 93 is mounted on the UV sensor 10 mounting side of the signal processing circuit board 90 has been shown. However, the signal processing circuit element 93 is on the opposite side of the UV sensor 10 mounting side. You may mount on a mounting surface. That is, only the UV sensor 10 must be mounted on the opening 201 side of the signal processing circuit board 90, but other electronic components and components do not need to limit the mounting surface.

また、上述の説明では、信号処理回路基板９０を誘電体基板で構成する例を示したが、当該誘電体基板であっても内部に電子回路素子を内装する積層回路基板であってもよく、さらには、ポリミドフィルム等により形成されるフレキシブル基板を用いても良い。また、紫外線測定装置としてカバー部材とＵＶセンサと簡素な外部出力用の回路基板のみからなる構成として、信号処理回路素子等の機能を外部接続する他の装置に搭載するようにしても良い。   In the above description, an example in which the signal processing circuit board 90 is configured by a dielectric substrate has been shown. However, the signal processing circuit board 90 may be a laminated circuit board in which an electronic circuit element is housed, Furthermore, you may use the flexible substrate formed with a polyimide film etc. Further, as the ultraviolet ray measuring apparatus, it is possible to mount it on another apparatus for externally connecting functions such as a signal processing circuit element, etc., as a configuration comprising only a cover member, a UV sensor, and a simple circuit board for external output.

また、上述の説明では、銀薄膜を利用する例を示したが、可視光を反射し、紫外線を透過する素材であれば、他の素材を用いても良い。   Moreover, although the example using a silver thin film was shown in the above-mentioned description, as long as it is a material which reflects visible light and permeate | transmits an ultraviolet-ray, you may use another material.

また、上述の説明では、電池を用いた例を示したが、外部から電力供給を受ける電源ケーブルを備えて、外部供給電力により駆動するようにしても良い。   Moreover, although the example using a battery was shown in the above description, a power cable that receives power supply from the outside may be provided and driven by external supply power.

また、上述の説明では、カバー部材４０にＵＶセンサ１０の受波面１１が当接する例を示したが、カバー部材４０と受波面１１とを離間し、これらの間に紫外線を屈折する屈折層を設けるようにしてもよい。この際、屈折層は、カバー部材４０を透過した紫外線がＵＶセンサ１０の受波面１１に集光されるような構造にすれば良い。   In the above description, the example in which the wave receiving surface 11 of the UV sensor 10 is in contact with the cover member 40 has been described. However, the cover member 40 and the wave receiving surface 11 are separated from each other, and a refractive layer that refracts ultraviolet rays is interposed therebetween. You may make it provide. At this time, the refractive layer may have a structure in which the ultraviolet light transmitted through the cover member 40 is condensed on the wave receiving surface 11 of the UV sensor 10.

次に、第２の実施形態に係る紫外線測定装置について図を参照して説明する。   Next, an ultraviolet ray measuring apparatus according to a second embodiment will be described with reference to the drawings.

FIG. 2B also shows the transmission / reflection state of visible light and ultraviolet light.

図２に示す紫外線測定装置３００は、球体を一平面で切断したような形状からなる半球型筐体３１０Ａと、所定厚みを有する平板型筐体３１０Ｂの二つの筐体が一体化された筐体を有する。当該筐体は中空形状であり、半球型筐体３１０Ａの内部にはＵＶセンサ１０が設置され、平板型筐体３１０Ｂの内部には電池ホルダ９１、電池９２、信号処理回路素子９３が設置されている。また、半球状筐体３１０Ａから平板型筐体３１０Ｂに亘って、回路電極が形成されたフレキシブル基板９０Ｆが設置されている。フレキシブル基板９０Ｆは、半球型筐体３１０Ａ内のＵＶセンサ１０と、平板型筐体３１０Ｂ内の信号処理回路素子９３および電池ホルダ９１とを電気的に接続する。   An ultraviolet ray measuring apparatus 300 shown in FIG. 2 is a case in which two cases of a hemispherical case 310A having a shape obtained by cutting a sphere in one plane and a flat case 310B having a predetermined thickness are integrated. Have The casing is hollow, the UV sensor 10 is installed inside the hemispherical casing 310A, and the battery holder 91, the battery 92, and the signal processing circuit element 93 are installed inside the flat casing 310B. Yes. A flexible substrate 90F on which circuit electrodes are formed is installed from the hemispherical housing 310A to the flat housing 310B. The flexible substrate 90F electrically connects the UV sensor 10 in the hemispherical casing 310A, the signal processing circuit element 93 and the battery holder 91 in the flat casing 310B.

半球型筐体３１０Ａは、前記切断面に対応する平面壁と、球体の曲面に対応する曲面壁とからなり、平面壁は、ほぼ全面が開口されており、当該開口部３０１には、カバー部材４０が全面を覆うように設置されている。カバー部材４０は、第１の実施形態と同様に、透光性を有するガラス基板４１と銀薄膜４２との二層構造からなり、半球型筐体３１０Ａの内部側に銀薄膜４２が配置されるように設置されている。   The hemispherical housing 310A includes a flat wall corresponding to the cut surface and a curved wall corresponding to the curved surface of the sphere, and the entire surface of the flat wall is opened, and the opening 301 includes a cover member. 40 is installed so as to cover the entire surface. Similar to the first embodiment, the cover member 40 has a two-layer structure of a light-transmitting glass substrate 41 and a silver thin film 42, and the silver thin film 42 is disposed on the inner side of the hemispherical casing 310A. It is installed as follows.

銀薄膜４２のガラス基板４１と反対側の面には、接着剤９４を用いてフレキシブル基板９０Ｆが固定設置されている。この際、接着剤９４は、少なくとも紫外線と透過する素材により形成されるとなお良い。   On the surface of the silver thin film 42 opposite to the glass substrate 41, a flexible substrate 90F is fixedly installed using an adhesive 94. At this time, the adhesive 94 is more preferably formed of a material that transmits at least ultraviolet rays.

フレキシブル基板９０Ｆは、上述のように、半球型筐体３１０Ａから平板型筐体３１０Ｂに亘る長尺形状からなる。この際、フレキシブル基板９０Ｆは、ＵＶセンサ１０と信号処理回路素子９３および電池ホルダ９１とを電気的に接続可能な最小限度の形状で形成すると良い。また、このフレキシブル基板９０Ｆも、接着剤９４と同様に、少なくとも紫外線を通過する素材により形成されるとなお良い。   As described above, the flexible substrate 90F has a long shape extending from the hemispherical casing 310A to the flat casing 310B. At this time, the flexible substrate 90F is preferably formed in a minimum shape that allows the UV sensor 10, the signal processing circuit element 93, and the battery holder 91 to be electrically connected. The flexible substrate 90F is also preferably formed of a material that passes at least ultraviolet rays, like the adhesive 94.

フレキシブル基板９０Ｆの銀薄膜４２と反対の面には、ＵＶセンサ１０が実装されている。この際、ＵＶセンサ１０は受波面１１がフレキシブル基板９０Ｆ側と反対側になるように、すなわち半球型筐体３１０Ａの曲面壁側を向くように実装される。また、ＵＶセンサ１０は、半球型筐体３１０Ａを開口部３０１側から見た当該開口部３０１の略中央に配置されるように実装される。   The UV sensor 10 is mounted on the surface of the flexible substrate 90F opposite to the silver thin film 42. At this time, the UV sensor 10 is mounted so that the wave receiving surface 11 is opposite to the flexible substrate 90F, that is, facing the curved wall side of the hemispherical casing 310A. Further, the UV sensor 10 is mounted so as to be arranged at the approximate center of the opening 301 when the hemispherical housing 310A is viewed from the opening 301 side.

半球型筐体３０１Ａを曲面壁の内面には、アルミニウム等の紫外線を反射する材質からなる反射膜５０が形成されている。ここで、曲面壁の内面は、カバー部材４０を介して半球状筐体３０１Ａ内に入射された紫外線が反射膜５０で反射して、ＵＶセンサ１０に集光されるような形状に形成されている。   A reflective film 50 made of a material that reflects ultraviolet rays, such as aluminum, is formed on the inner surface of the curved wall of the hemispherical casing 301A. Here, the inner surface of the curved wall is formed in such a shape that the ultraviolet light incident into the hemispherical housing 301 </ b> A via the cover member 40 is reflected by the reflective film 50 and condensed on the UV sensor 10. Yes.

このような構造とすることで、図２（Ｂ）に示すように、開口部３０１から光が入射すると、可視光以上の波長からなる光はカバー部材４０の銀薄膜４２で反射され、紫外線は銀薄膜４２を透過して反射膜５０で反射されて集中的にＵＶセンサ１０で受波される。これにより、より効率良く紫外線測定を行うことができる。この際、信号処理回路素子９３および電池ホルダ９１等のＵＶセンサ１０以外の素子を、半球状筐体３０１Ａ内に配置しないことで、開口部３０１から入射した紫外線が，前記ＵＶセンサ１０以外の素子により遮光されないので、より効率良く紫外線測定を行うことができる。   With this structure, as shown in FIG. 2B, when light is incident from the opening 301, light having a wavelength longer than visible light is reflected by the silver thin film 42 of the cover member 40, and ultraviolet rays are emitted. The light is transmitted through the silver thin film 42, reflected by the reflective film 50, and intensively received by the UV sensor 10. Thereby, ultraviolet measurement can be performed more efficiently. At this time, elements other than the UV sensor 10 such as the signal processing circuit element 93 and the battery holder 91 are not arranged in the hemispherical housing 301A, so that the ultraviolet rays incident from the opening 301 are elements other than the UV sensor 10. Therefore, ultraviolet rays can be measured more efficiently.

なお、上述の説明では、フレキシブル基板９０Ｆを用いた例を示したが、銀薄膜４２の表面に絶縁層を設けた上で、ＩＴＯ等の透明電極を形成し、当該透明電極上にＵＶセンサ１０を実装するようにしても良い。   In the above description, an example using the flexible substrate 90F has been shown. However, a transparent electrode such as ITO is formed on the surface of the silver thin film 42, and the UV sensor 10 is formed on the transparent electrode. May be implemented.

また、上述の説明では、球体を切断した半球形状の筐体を用いた例を示したが、楕円球体等であっても、ＵＶセンサ１０への集光を行える形状のものであれば、半球形状に限る必要はない。   In the above description, an example using a hemispherical casing obtained by cutting a sphere has been described. However, even an elliptical sphere or the like may be hemisphere as long as it has a shape capable of focusing on the UV sensor 10. The shape need not be limited.

次に、第３の実施形態に係る紫外線測定装置を用いたコンパクトケースについて説明する。   Next, a compact case using the ultraviolet ray measuring apparatus according to the third embodiment will be described.

図３（Ａ）は本実施形態のコンパクトケースの概略の外観斜視図であり、図３（Ｂ）は当該コンパクトケースの主要構成を示す構成図である。   FIG. 3A is a schematic external perspective view of the compact case of the present embodiment, and FIG. 3B is a configuration diagram showing a main configuration of the compact case.

図３に示すように、本実施形態のコンパクトケース４００は、鏡として用いられる第１筐体４１０Ａと、ファンデーション等の化粧品４１１を格納することを主機能とする第２筐体４１０Ｂとが、ヒンジ４１０Ｃにより回動可能に接続されてなる。   As shown in FIG. 3, the compact case 400 of the present embodiment has a first housing 410A used as a mirror and a second housing 410B whose main function is to store cosmetics 411 such as a foundation. It is connected by 410C so that rotation is possible.

第１筐体４１０Ａは略円板形状を成し、第１の実施形態の紫外線測定装置と同様に、内部にＵＶセンサ１０、信号処理回路基板９０、信号処理回路素子９３、および電池９２が装着された電池ホルダ９１を有し、開口部にカバー部材４０を備える。これら構成部材の設置位置関係や接続関係は、第１の実施形態と同じであるか類似する構造であるので、説明は、省略する。   The first housing 410A has a substantially disk shape, and the UV sensor 10, the signal processing circuit board 90, the signal processing circuit element 93, and the battery 92 are mounted therein, as in the ultraviolet ray measuring apparatus of the first embodiment. The battery holder 91 is provided, and the cover member 40 is provided in the opening. Since the installation position relationship and the connection relationship of these components are the same as or similar to those in the first embodiment, description thereof will be omitted.

カバー部材４０は、ガラス基板４１と銀薄膜４２との二層構造からなり、銀鏡として機能する。すなわち、このカバー部材４０が、紫外線を選択して透過させる機能を有するとともに、コンパクトケース４００の鏡として機能する。   The cover member 40 has a two-layer structure of a glass substrate 41 and a silver thin film 42, and functions as a silver mirror. That is, the cover member 40 has a function of selecting and transmitting ultraviolet rays and functions as a mirror of the compact case 400.

このため、本実施形態のコンパクトケース４００のような元々鏡が必須構成である製品であれば、新たな紫外線選択部材を必要とすることなく、紫外線測定装置としての機能を付け加えることができる。この際、紫外線測定に関する機能部としては、外観的になにも変化させる必要がないので、デザイン性を低下させることなく、コンパクトケースに紫外線測定機能を追加することができる。   For this reason, if it is a product from which the mirror is an essential structure like the compact case 400 of this embodiment, the function as an ultraviolet-ray measuring apparatus can be added, without requiring a new ultraviolet-ray selection member. At this time, since it is not necessary to change the appearance of the functional unit related to the ultraviolet measurement, the ultraviolet measurement function can be added to the compact case without deteriorating the design.

なお、本実施形態では図示していないが、第１筐体４１０Ａや第２筐体４１０Ｂに、ＬＥＤ等からなる簡素な構造の表示器を設置することで、ＵＶセンサ１０で受波して得られた紫外線量を信号処理回路素子９３等で解析し、取得した紫外線量に応じた注意表示等を行うことができる。これにより、コンパクトケース４００のような化粧器具であれば、紫外線量に応じた化粧品の情報提供も行うことができる。   Although not shown in the present embodiment, it can be obtained by receiving a wave by the UV sensor 10 by installing a display device having a simple structure such as an LED in the first housing 410A or the second housing 410B. The obtained ultraviolet ray amount is analyzed by the signal processing circuit element 93 or the like, and a caution display or the like corresponding to the obtained ultraviolet ray amount can be performed. Thereby, if it is a cosmetics instrument like the compact case 400, the cosmetics information according to the amount of ultraviolet rays can also be provided.

次に、第４の実施形態に係る紫外線測定機能を備えた電子機器の構成について図を参照して説明する。   Next, the configuration of an electronic apparatus having an ultraviolet measurement function according to the fourth embodiment will be described with reference to the drawings.

図４は紫外線測定機能を備えた電子機器としての携帯電話機を例にした主要構成図であり、図４（Ａ）は携帯電話機５００の表面図、図４（Ｂ）は携帯電話機５００の側面断面図、図４（Ｃ）は携帯電話機５００の裏面図を示す。   4A and 4B are main configuration diagrams exemplifying a mobile phone as an electronic device having an ultraviolet measurement function. FIG. 4A is a front view of the mobile phone 500, and FIG. FIG. 4 and FIG. 4C are rear views of the mobile phone 500.

携帯電話機５００は、平板形状の筐体５１０を有し、表面にＬＣＤ等からなる表示モジュール５１２と、ユーザの操作入力を受け付ける複数の操作子５１４とが配置されている。これらの表示モジュール５１２や各操作子５１４は、メインモジュール基板５１１に実装されたり、タクトスイッチ等を介して接続されている。メインモジュール基板５１１には、図示しない各種の電子回路素子が実装または内装されており、携帯電話機５００としてのアプリケーション実行処理を実現する。   The mobile phone 500 has a flat-plate-shaped casing 510, and a display module 512 made of an LCD or the like on the surface and a plurality of operators 514 that accept user input. The display module 512 and each operation element 514 are mounted on the main module substrate 511 or connected via a tact switch or the like. Various electronic circuit elements (not shown) are mounted or built in the main module substrate 511, and an application execution process as the mobile phone 500 is realized.

筐体５１０の裏面側には携帯電話機５００としての電池部５１３（二次電池パックと電池接続部材）が内装されており、当該電池部５１３からメインモジュール基板５１１等に電力が供給される。   A battery unit 513 (secondary battery pack and battery connecting member) as a mobile phone 500 is provided on the back side of the housing 510, and power is supplied from the battery unit 513 to the main module substrate 511 and the like.

また、筐体５１０の裏面側には、開口部が形成されており、当該開口部にカバー部材４０が設置されている。カバー部材４０は、上述の各実施形態と同じようにガラス基板４１と銀薄膜４２との二層構造からなり、紫外線選択機能を有するとともに銀鏡として機能する。   In addition, an opening is formed on the rear surface side of the housing 510, and the cover member 40 is installed in the opening. The cover member 40 has a two-layer structure of a glass substrate 41 and a silver thin film 42 as in the above-described embodiments, and has an ultraviolet ray selection function and functions as a silver mirror.

さらに、筐体５１０内におけるメインモジュール基板５１１の裏面側で、且つカバー部材４０に覆われる領域内には、ＵＶセンサ１０が設置されている。この際、ＵＶセンサ１０は、受波面１１が銀薄膜４２に当接するように設置されている。一方で、ＵＶセンサ１０は、紫外線観測結果に基づく信号を出力する信号処理回路素子９３等を備える信号処理回路基板９０に実装されており、この信号処理回路基板９０がメインモジュール基板５１１に実装される。このように、メインモジュール基板５１１に電気的に接続することで、信号処理回路基板９０を介して、ＵＶセンサ１０や信号処理回路素子９３は、携帯電話機５００の電池部５１３から電力供給を受けることができる。   Furthermore, the UV sensor 10 is installed in the area covered by the cover member 40 on the back surface side of the main module substrate 511 in the housing 510. At this time, the UV sensor 10 is installed such that the wave receiving surface 11 is in contact with the silver thin film 42. On the other hand, the UV sensor 10 is mounted on a signal processing circuit board 90 including a signal processing circuit element 93 that outputs a signal based on the ultraviolet observation result, and the signal processing circuit board 90 is mounted on the main module board 511. The As described above, by electrically connecting to the main module substrate 511, the UV sensor 10 and the signal processing circuit element 93 are supplied with power from the battery unit 513 of the mobile phone 500 via the signal processing circuit substrate 90. Can do.

このように、本実施形態の構成を用いることで、携帯電話機５００のデザイン性を低下させることなく、紫外線測定装置を携帯電話機５００に組み込むことができる。さらに、携帯電話機５００の電源を利用することで、紫外線測定装置としての電源を省略することができる。また、携帯電話機５００のメインモジュール基板５１１で実行されるアプリケションに紫外線観測機能のアプリケーションを備えさせることで、この観測結果を携帯電話機５００の表示部材５１２上に表示させることができる。これにより、紫外線測定装置として専用の表示部を用いる必要もなく、ユーザに紫外線観測結果を容易に提供することができる。   Thus, by using the configuration of the present embodiment, the ultraviolet ray measuring device can be incorporated into the mobile phone 500 without degrading the design of the mobile phone 500. Furthermore, by using the power source of the mobile phone 500, the power source as the ultraviolet ray measuring device can be omitted. Further, by providing an application executed on the main module substrate 511 of the mobile phone 500 with an application of an ultraviolet ray observation function, the observation result can be displayed on the display member 512 of the mobile phone 500. Thereby, it is not necessary to use a dedicated display unit as the ultraviolet ray measuring apparatus, and the ultraviolet ray observation result can be easily provided to the user.

なお、上述の説明では、携帯電話機を例に示したが、図５に示すようにポータブル型のパーソナルコンピュータに紫外線測定装置としての機能を組み込むようにしても良い。   In the above description, the cellular phone is taken as an example. However, as shown in FIG. 5, a function as an ultraviolet ray measuring apparatus may be incorporated in a portable personal computer.

図５に示すように、モバイルＰＣ６００は、表示側筐体６１０Ａと操作側筐体６１０Ｂとが回動可能に接続されてなる。表示側筐体６１０Ａの表面側には液晶ディスプレイ等の表示モジュール６１１が設置されており、操作側モジュール６１０Ｂの表面側には複数の操作子６１２が設置されている。   As shown in FIG. 5, the mobile PC 600 includes a display-side housing 610A and an operation-side housing 610B that are rotatably connected. A display module 611 such as a liquid crystal display is installed on the surface side of the display-side housing 610A, and a plurality of operating elements 612 are installed on the surface side of the operation-side module 610B.

そして、表示側筐体６１０Ａの裏面側は、所定の枠部の残して大きく開口されており、当該開口部にカバー部材４０が設置されている。カバー部材４０は、上述の各説明に記載のように、ガラス基板と銀薄膜との二層構造からなり、銀薄膜が筐体の内側になるように配置されている。表示側筐体６１０Ａ内のカバー部材４０によって覆われる領域の略中心には、ＵＶセンサ１０が設置されている。ＵＶセンサ１０は、図示しない信号処理回路基板へ実装され、信号処理回路基板はメインモジュール基板へ実装される。このように本発明の紫外線測定装置は、モバイルＰＣにも装備することができる。この際、デザイン性を低下させることなくモバイルＰＣへ紫外線測定機能を追加することができる。また、モバイルＰＣのように画素数の多い表示画面を有し、処理能力の高いＣＰＵを用いた電子機器に装備することで、紫外線観測結果をより高速に出力することができ、且つ当該紫外線観測結果に基づく、より豊富な情報を表示することができる。   And the back side of display side housing | casing 610A is largely opened leaving the predetermined frame part, and the cover member 40 is installed in the said opening part. As described in each of the above descriptions, the cover member 40 has a two-layer structure of a glass substrate and a silver thin film, and is arranged so that the silver thin film is inside the housing. The UV sensor 10 is installed at the approximate center of the area covered by the cover member 40 in the display-side housing 610A. The UV sensor 10 is mounted on a signal processing circuit board (not shown), and the signal processing circuit board is mounted on a main module board. As described above, the ultraviolet ray measuring apparatus of the present invention can also be installed in a mobile PC. At this time, an ultraviolet ray measuring function can be added to the mobile PC without degrading the design. In addition, it is possible to output UV observation results at a higher speed by installing it on an electronic device using a CPU with a high processing capability, such as a mobile PC, which has a display screen with a large number of pixels, and the UV observation. A richer information based on the result can be displayed.

なお、上述の説明では、携帯電話機およびモバイルＰＣを例に説明したが、ＰＤＡや携帯型ミュージックプレイヤ、歩数計等の他の携帯用電子機器にも当該構成を適用することができる。   In the above description, a mobile phone and a mobile PC have been described as examples. However, the configuration can also be applied to other portable electronic devices such as a PDA, a portable music player, and a pedometer.
