　筐体１１０は、光源１０２などを収容する箱状の部材であり、光源１０２から出射される光を外部に漏出させない遮光性を備えている。また筐体１１０は、室内照明や太陽光など筐体１１０外に光源が存在する光を遮断する遮光性も備えている。筐体１１０の一部には、光源１０２から照射される光を外部に出射させる開口１０１が設けられている。 The housing 110 is a box-shaped member that accommodates the light source 102 and the like, and has a light shielding property that prevents light emitted from the light source 102 from leaking outside. The housing 110 also has a light shielding property that blocks light such as room lighting and sunlight that is present outside the housing 110. A part of the housing 110 is provided with an opening 101 for emitting light emitted from the light source 102 to the outside.
　筐体１１０に貫通状に設けられた孔である開口１０１は、光照射装置１００の筐体１１０の内部から外方に向かって光を出射する部分であり、本実施の形態の場合は、人の皮膚などに押し付けられる部分である。 The opening 101 that is a hole provided in the housing 110 in a penetrating manner is a portion that emits light from the inside of the housing 110 of the light irradiation device 100 to the outside. This is the part that is pressed against the skin.
　光源１０２は、対象物の表面、例えば皮膚や毛根など人体の表面に存在する部分に作用して影響を与えることができる光２００を出射することができる素子である。具体的に例えば、レーザダイオードや、発光ダイオードなどの単一波長の光を出射する素子や、キセノンランプなど比較的広い波長範囲の光を出射する素子、またこれらを複合的に組み合わせた素子群であってもかまわない。本実施の形態の場合、光源１０２として近赤外の光２００を出射するレーザダイオードを例示して説明する。 The light source 102 is an element that can emit light 200 that can act on and influence the surface of an object, for example, the surface of a human body such as skin or hair root. Specifically, for example, an element that emits light of a single wavelength such as a laser diode or a light emitting diode, an element that emits light of a relatively wide wavelength range such as a xenon lamp, or an element group that combines these elements. It does not matter. In the case of this embodiment, a laser diode that emits near-infrared light 200 will be described as an example of the light source 102.
　光学系１０６は、光源１０２から出射される光２００を導光し、人に対する処理に適した光２００にするために光学部材が組み合わされている。例えば光学系１０６を構成する光学部材としては、レンズや、絞り、ミラーなどである。 The optical system 106 is combined with an optical member to guide the light 200 emitted from the light source 102 and make the light 200 suitable for processing humans. For example, the optical member constituting the optical system 106 is a lens, a diaphragm, a mirror, or the like.
　光センサ１０３は、筐体１１０内に配置され、筐体１１０の一部が破損し筐体１１０の外から内方に入射した外光を検出するセンサである。光センサ１０３は光を検知する素子が配置される面である受光面１３１を有する。本実施の形態の場合、受光面１３１は、図１の２点鎖線で示すように、光源１０２が配置されている位置から開口１０１に至る筐体１１０の内面である光源光到達予想領域１３２の少なくとも一部を臨むように配置されている。光源光到達予想領域１３２とは、光照射装置１００が強い衝撃などを受けて光源１０２や光学系１０６がずれたり外れたり破損したりした場合を想定し、光源１０２から照射された光が到達する可能性があると予測した筐体１１０内面の領域である。 The optical sensor 103 is a sensor that is arranged in the housing 110 and detects external light that is incident on the inside from the outside of the housing 110 when a part of the housing 110 is damaged. The optical sensor 103 has a light receiving surface 131 on which an element for detecting light is disposed. In the case of the present embodiment, the light receiving surface 131 is a light source light arrival prediction region 132 that is the inner surface of the housing 110 from the position where the light source 102 is arranged to the opening 101 as shown by a two-dot chain line in FIG. It is arranged to face at least a part. The light source light arrival prediction region 132 assumes a case where the light irradiation device 100 receives a strong impact or the like, and the light source 102 or the optical system 106 is displaced, disconnected, or damaged, and the light irradiated from the light source 102 reaches. This is an area on the inner surface of the housing 110 that is predicted to be possible.
　光センサ１０３は、筐体１１０内方に侵入する外光を検出できるものであれば、特に限定されるものではないが、フォトダイオードを用いたセンサや硫化カドミウム（ＣｄＳ）セルなどのフォトレジスタを用いたセンサなどを挙示できる。 The optical sensor 103 is not particularly limited as long as it can detect external light entering the inside of the housing 110. However, a sensor using a photodiode or a photoresistor such as a cadmium sulfide (CdS) cell is used. The sensors used can be listed.
　光センサ１０３の受光面１３１が臨む面は、光源光到達予想領域１３２の中であって、筐体１１０の脆弱領域を含むことが好ましい。筐体１１０の脆弱領域とは、例えば、リブとリブとの間の中央領域、強い衝撃力を受ける可能性の高い筐体１１０の角部、外方に向かって突出する突起部の周縁などである。 It is preferable that the surface that the light receiving surface 131 of the optical sensor 103 faces is in the light source light arrival prediction region 132 and includes the fragile region of the housing 110. The weak region of the housing 110 is, for example, a central region between ribs, a corner of the housing 110 that is highly likely to receive a strong impact force, a peripheral edge of a protruding portion that protrudes outward, and the like. is there.
　筐体１１０の一部に所定の衝撃力が加わると破損する脆弱領域を積極的に設け、積極的に設けた脆弱領域を含む領域を臨むように光センサ１０３の受光面１３１を配置してもかまわない。脆弱領域を積極的に設けるとは、例えば筐体１１０の肉厚を一部薄くしたり脆くしたりすることである。 Even if a weak region that is damaged when a predetermined impact force is applied to a part of the housing 110 is actively provided, and the light receiving surface 131 of the optical sensor 103 is disposed so as to face the region including the weak region that is actively provided. It doesn't matter. Providing the fragile region positively means, for example, partially reducing the thickness of the housing 110 or making it fragile.
　筐体１１０内に配置する光センサ１０３の数は、特に限定されるものではない。本実施の形態の場合、光センサ１０３は、光学系１０６の光源１０２側の端部に、円周上均等に４箇所設けられている。なお、図１には４個の光センサ１０３のうち径方向に並ぶ２つの光センサ１０３が記載されている。 The number of optical sensors 103 arranged in the housing 110 is not particularly limited. In the case of the present embodiment, the optical sensors 103 are provided at four positions equally on the circumference at the end of the optical system 106 on the light source 102 side. FIG. 1 shows two optical sensors 103 arranged in the radial direction among the four optical sensors 103.
　遮光部材１０５は、筐体１１０に貫通状に設けられる開口１０１を塞ぐことにより、筐体１１０の外部から内部に外光を侵入させないための部材である。また、遮光部材１０５は、光源１０２が出射する光を筐体１１０の外に出射させない機能も備えている。 The light shielding member 105 is a member for preventing outside light from entering the inside of the housing 110 from the outside by closing the opening 101 provided in a penetrating manner in the housing 110. The light shielding member 105 also has a function of preventing the light emitted from the light source 102 from being emitted outside the housing 110.
　遮光部材１０５の形状や開閉構造などは特に限定されるものではなく、周知技術を任意に採用することができる。また、遮光部材１０５の開閉動作は、手動で実行してもよく、また、モータ等の開閉駆動源を備えて自動で実行してもよい。本実施の形態の場合、遮光部材１０５には開閉検知部１５１が接続されており、開閉検知部１５１により遮光部材１０５が開状態か閉状態かを検知してその旨を示す情報を出力する。 The shape and opening / closing structure of the light shielding member 105 are not particularly limited, and any well-known technique can be arbitrarily adopted. Further, the opening / closing operation of the light shielding member 105 may be performed manually, or may be automatically performed by providing an opening / closing drive source such as a motor. In the present embodiment, an opening / closing detection unit 151 is connected to the light shielding member 105, and the opening / closing detection unit 151 detects whether the light shielding member 105 is in an open state or a closed state, and outputs information indicating that.
　図２は、第１の実施の形態に係る制御部の機能部を制御部に接続される機構部等と共に示すブロック図である。 FIG. 2 is a block diagram showing a functional unit of the control unit according to the first embodiment together with a mechanism unit and the like connected to the control unit.
　制御部１０４は、光センサ１０３から取得する情報に基づき、光源１０２に所定光量の光を出射させるか否かを制御する装置である。 The control unit 104 is a device that controls whether the light source 102 emits a predetermined amount of light based on information acquired from the optical sensor 103.
　ここで、所定光量とは人体など対象物に対して所望の処理を行う事ができる程度の光量を意味し、例えば処理の位置を示すためのみに対象物に照射される弱い光を除外する意味で用いている。また、所定光量の光２００を出射させるとは、例えば、光源１０２を消灯状態から点灯させる場合だけではなく、光源１０２からは同じ光量のパルス状の光が周期的に出射しているが、安全上問題のないデューティー比から所望の処理を行う事ができるデューティー比に変更する場合も含まれる。また、光源１０２から所定の光量の光２００が出射しているが、シャッターなどの物理的機構により遮られることにより開口１０１から光２００が出射していない状態からシャッターなどを解放して出射させる場合も所定光量の光２００を出射させることになる。 Here, the predetermined amount of light means the amount of light that can perform a desired process on an object such as a human body, and for example, excludes weak light that is irradiated on the object only to indicate the position of the process. Used in. In addition, for example, the light 200 having a predetermined light amount is emitted not only when the light source 102 is turned on from a light-off state, but also when the light source 102 periodically emits pulsed light with the same light amount. It also includes a case where the duty ratio is changed from a duty ratio that does not cause a problem to a duty ratio at which a desired process can be performed. In addition, when the light source 102 emits a predetermined amount of light 200 but is blocked by a physical mechanism such as a shutter, the shutter 200 is released from the state where the light 200 is not emitted from the opening 101 and emitted. Also, a predetermined amount of light 200 is emitted.
　制御部１０４の具体的な態様は特に限定されるものではない。例えば、入出力素子と演算素子と記憶素子とを組み合わせ、記憶素子に記憶されているプログラムを実行することにより制御を行ういわゆるコンピュータや、電子部品を組み合わせた回路に基づき制御を行うものが制御部１０４に含まれる。また、リンク機構、カム機構、および、歯車機構等の１つまたは複数を組み合わせて光２００の出射を制御するものも制御部１０４に含まれる。 The specific aspect of the control unit 104 is not particularly limited. For example, what is called a computer that performs control by combining an input / output element, an arithmetic element, and a storage element, and executes a program stored in the storage element, or a control unit that performs control based on a circuit that combines electronic components 104. The control unit 104 includes one that controls the emission of the light 200 by combining one or more of a link mechanism, a cam mechanism, and a gear mechanism.
　図３は、光照射装置の動作を制御部の処理の流れと共に説明するフローチャートである。 FIG. 3 is a flowchart for explaining the operation of the light irradiation apparatus together with the processing flow of the control unit.
　光照射装置１００を使用する使用者は、光照射装置１００から光を出射させるために、筐体１１０に設けられたスイッチ１０９を操作し、主電源１０８がＯＮになるように操作する（ステップＳ１０１）。具体的には、制御部１０４の処理判断部１４１が、スイッチ１０９からの信号を受信すると、電源開閉部１４８に電源の受入を指示し、電源開閉部１４８は、主電源１０８からの電源の供給を受け入れるように処理を行う（ステップＳ１０２）。 A user using the light irradiation device 100 operates the switch 109 provided on the housing 110 to emit light from the light irradiation device 100 and operates the main power supply 108 to be turned on (step S101). ). Specifically, when the processing determination unit 141 of the control unit 104 receives a signal from the switch 109, the power supply switching unit 148 instructs the power supply switching unit 148 to accept power, and the power supply switching unit 148 supplies power from the main power supply 108. (Step S102).
　次に、処理判断部１４１は、光源１０２に所定光量の光を照射させる前に、遮光部材１０５が開口１０１を塞いだ状態か否かを開閉検知部１５１に問いあわせる。開閉検知部１５１は、遮光部材１０５の状態を示す情報を処理判断部１４１に出力する。 Next, the process determination unit 141 inquires of the open / close detection unit 151 whether or not the light shielding member 105 is blocking the opening 101 before irradiating the light source 102 with a predetermined amount of light. The open / close detection unit 151 outputs information indicating the state of the light shielding member 105 to the process determination unit 141.
　遮光部材１０５が開状態である場合（ステップＳ１０３：Ｙｅｓ）、遮光部材１０５を閉状態とする旨を示す情報を処理判断部１４１が報知する（ステップＳ１０４）。 When the light shielding member 105 is in the open state (step S103: Yes), the process determination unit 141 notifies information indicating that the light shielding member 105 is in the closed state (step S104).
　遮光部材１０５の開閉が手動で行われる場合、遮光部材１０５を閉状態とする旨を示す情報の報知は、例えば、光照射装置１００に設けられた表示装置（図示せず）にその情報を表示したり、表示用ランプの発光を変化させたり、ブザー音など音の発生させることにより報知する。 When the light shielding member 105 is manually opened and closed, notification of information indicating that the light shielding member 105 is in a closed state is displayed, for example, on a display device (not shown) provided in the light irradiation device 100. Or by changing the light emission of the display lamp or generating a sound such as a buzzer.
　一方、遮光部材１０５の開閉が自動で行われる場合、遮光部材１０５を閉状態とする旨を示す情報を取得した遮光部材開閉部（図示せず）は、遮光部材１０５が閉状態となるように遮光部材１０５を駆動する。 On the other hand, when the light shielding member 105 is automatically opened and closed, the light shielding member opening / closing unit (not shown) that has acquired information indicating that the light shielding member 105 is in the closed state is configured so that the light shielding member 105 is in the closed state. The light shielding member 105 is driven.
　次に、遮光部材１０５が閉状態である場合、または、遮光部材１０５が閉状態になった場合（ステップＳ１０３：Ｎｏ）、処理判断部１４１は、光量判断部１４３に光センサ１０３が検出した外光の光量が所定の第一閾値以上か否かを判断させる（ステップＳ１０５）。 Next, when the light shielding member 105 is in the closed state, or when the light shielding member 105 is in the closed state (step S103: No), the process determining unit 141 causes the light amount determining unit 143 to detect the outside of the light sensor 103. It is determined whether the amount of light is greater than or equal to a predetermined first threshold (step S105).
　複数の光センサ１０３から取得した情報のうち１つでも所定の第一閾値以上の光量を示す情報がある場合（ステップＳ１０５：Ｙｅｓ）、光量判断部１４３は、図４に示すように、筐体１１０の一部に破損部１１１が存在し、破損部１１１から外光３００が筐体１１０内に入射していると判断し、その旨を示す情報を処理判断部１４１に出力する。 When at least one piece of information acquired from the plurality of optical sensors 103 includes information indicating a light amount that is equal to or greater than a predetermined first threshold (step S105: Yes), the light amount determination unit 143 includes a housing as shown in FIG. It is determined that the damaged portion 111 exists in a part of 110, the external light 300 is incident on the housing 110 from the damaged portion 111, and information indicating that is output to the processing determining portion 141.
　外光３００が筐体１１０内に入射している情報を取得した処理判断部１４１は、筐体１１０が破損している旨を示す情報を報知し（ステップＳ１０６）、光源１０２に所定光量の光２００を出射させることなく一連の動作を終了する。 The process determination unit 141 that has acquired the information that the external light 300 is incident on the housing 110 notifies the information indicating that the housing 110 is damaged (step S106), and the light source 102 has a predetermined amount of light. A series of operations are terminated without emitting 200.
　一方、光量判断部１４３が複数の光センサ１０３から取得した情報の全てが所定の第一閾値未満の光量を示す情報である場合（ステップＳ１０５：Ｎｏ）、光量判断部１４３は、筐体１１０に破損部１１１はなく正常である旨を示す情報を処理判断部１４１に出力する。 On the other hand, when all of the information acquired by the light amount determination unit 143 from the plurality of optical sensors 103 is information indicating a light amount that is less than the predetermined first threshold (step S105: No), the light amount determination unit 143 is attached to the housing 110. Information indicating that there is no damaged part 111 and that it is normal is output to the process determining part 141.
　筐体１１０が正常である旨を示す情報を取得した処理判断部１４１は、遮光部材１０５を開状態にする旨を示す情報を報知し（ステップＳ１０７）、光源１０２に所定光量の光２００を出射させるよう光源駆動部１４２を制御する（ステップＳ１０８）。 The process determination unit 141 that has acquired information indicating that the casing 110 is normal notifies the information indicating that the light shielding member 105 is opened (step S107), and emits a predetermined amount of light 200 to the light source 102. The light source driving unit 142 is controlled so as to be performed (step S108).
　以上により、所定光量の光２００を開口１０１から出射する前に、筐体１１０の破損の有無を確認し、筐体１１０に破損が存在している場合は、光源１０２から所定の光量の光２００が出射することはない。従って、不本意に光２００が使用者などの眼に入射することを防止できる。 As described above, before the light 200 having a predetermined light amount is emitted from the opening 101, the presence or absence of damage to the housing 110 is confirmed. When the housing 110 is damaged, the light 200 having a predetermined light amount is emitted from the light source 102. Does not exit. Therefore, it is possible to prevent the light 200 from entering the eyes of the user or the like unintentionally.
　次に、光源１０２から所定光量の光２００を出射中は、光量判断部１４３が複数の光センサ１０３からの情報を所定の間隔で判断し続け、外光３００が筐体１１０内に入射したか否かをチェックし、その結果を処理判断部１４１に出力し続ける。ここで、光量判断部１４３は、第一閾値よりも高い第二閾値を用いて筐体１１０に破損が発生したか否かを判断する。これは、開口している開口１０１から外光が入ってくるため開口１０１が閉じているときよりも筐体１１０内が明るくなっているからである。 Next, while the light 200 having a predetermined light amount is emitted from the light source 102, the light amount determination unit 143 continues to determine information from the plurality of optical sensors 103 at predetermined intervals, and whether the external light 300 has entered the housing 110. It is checked whether or not, and the result is continuously output to the process determination unit 141. Here, the light quantity determination unit 143 determines whether or not the casing 110 is damaged using a second threshold value higher than the first threshold value. This is because the inside of the housing 110 is brighter than when the opening 101 is closed because external light enters from the opening 101 that is open.
　複数の光センサ１０３から取得した情報のうち１つでも所定の第二閾値以上の光量を示す情報がある場合、光量判断部１４３は、筐体１１０の一部に破損部１１１が発生し、例えば図４に示すように破損部１１１から外光３００が筐体１１０内に入射していると判断し、その旨を示す情報を処理判断部１４１に出力する（ステップＳ１０９：Ｙｅｓ）。 When even one piece of information acquired from the plurality of optical sensors 103 has information indicating a light amount that is equal to or greater than a predetermined second threshold, the light amount determination unit 143 causes a damaged portion 111 to be generated in a part of the housing 110. As shown in FIG. 4, it is determined that the external light 300 is incident on the casing 110 from the damaged portion 111, and information indicating that is output to the process determining portion 141 (step S109: Yes).
　外光３００が筐体１１０内に入射している情報を取得した処理判断部１４１は、光源１０２から所定光量の光２００が出射されることを強制的に停止させる（ステップＳ１１０）。具体的に例えば、処理判断部１４１は、電源開閉部１４８を制御して、主電源１０８からの電源の供給を遮断することにより光源１０２の発光を強制停止させる。また、処理判断部１４１は、光源駆動部１４２割り込みをかけて、光源１０２の発光を強制停止させてもよい。以上の処理の後一連の動作を終了する。 The process determination unit 141 that has acquired the information that the external light 300 is incident on the housing 110 forcibly stops the emission of the light 200 having a predetermined light amount from the light source 102 (step S110). Specifically, for example, the process determination unit 141 controls the power supply opening / closing unit 148 to forcibly stop the light emission of the light source 102 by cutting off the supply of power from the main power supply 108. In addition, the process determining unit 141 may interrupt the light source driving unit 142 to forcibly stop the light emission of the light source 102. A series of operation | movement is complete | finished after the above process.
　一方、筐体１１０内への外光３００の入射がなく筐体１１０が破損していない場合（ステップＳ１０９：Ｎｏ）には、時間の経過による終了、使用者のスイッチ１０９操作による処理の終了などを示す情報を処理判断部１４１が取得するまで所定光量の光２００の出射が継続され（ステップＳ１１１:Ｎｏ）、情報を取得した場合（ステップＳ１１１：Ｙｅｓ）、処理判断部１４１は、光源駆動部１４２を制御して、光源１０２による所定光量の光２００の出射を停止させる(ステップＳ１１２）。以上により一連の動作が終了する。 On the other hand, when the external light 300 is not incident on the housing 110 and the housing 110 is not damaged (step S109: No), the processing ends due to the passage of time, the processing is ended by the user operating the switch 109, or the like. The process determining unit 141 continues the emission of the predetermined amount of light 200 until the process determining unit 141 acquires information (step S111: No), and when the information is acquired (step S111: Yes), the process determining unit 141 includes the light source driving unit. 142 is controlled to stop the emission of the predetermined amount of light 200 from the light source 102 (step S112). Thus, a series of operations is completed.
　以上説明した第１の実施の形態に係る光照射装置１００によれば、光源１０２から所定光量の光２００を出射する前に、筐体１１０内への外光３００の入射の有無で筐体１１０の破損をチェックし、破損があれば、所定光量の光２００を出射させない。そのため、光照射装置１００の保管中に筐体１１０が破損している場合などにおいて光源１０２からの光２００が筐体１１０外部に漏れ出すことを有効に防止することができる。 According to the light irradiation apparatus 100 according to the first embodiment described above, the case 110 is determined based on whether or not the external light 300 is incident on the case 110 before the light source 102 emits the light 200 having a predetermined light amount. If there is damage, the light 200 having a predetermined light amount is not emitted. Therefore, it is possible to effectively prevent the light 200 from the light source 102 from leaking outside the housing 110 when the housing 110 is damaged during storage of the light irradiation device 100.
　また、所定光量の光２００の出射中においては、常に筐体１１０の外光３００の入射をチェックしているため、筐体１１０が急に破損した場合でも光源１０２の発光を強制的に停止させることが可能となる。 In addition, since the incident of the external light 300 from the housing 110 is always checked during the emission of the predetermined amount of light 200, the light emission of the light source 102 is forcibly stopped even when the housing 110 is suddenly damaged. It becomes possible.
　従って、光源１０２が出射する光２００が不本意に使用者などの眼に入射することを防止出来る、光照射装置１００の人の眼に対する安全性をより高めることが可能となる。 Therefore, it is possible to further improve the safety of the light irradiation apparatus 100 to the human eye, which can prevent the light 200 emitted from the light source 102 from inadvertently entering the eyes of the user or the like.

　図５は、第２の実施の形態に係る光照射装置の内部構成を模式的に示す図である。 FIG. 5 is a diagram schematically showing the internal configuration of the light irradiation apparatus according to the second embodiment.
　本実施の形態に係る光照射装置１００は、第１の実施の形態で説明した光照射装置１００に加えて、外部光源１２９と、導光部材１１９とをさらに備えている。 The light irradiation device 100 according to the present embodiment further includes an external light source 129 and a light guide member 119 in addition to the light irradiation device 100 described in the first embodiment.
　外部光源１２９は、筐体１１０の外部に配置され、光センサ１０３が検出可能な光を出射する素子である。具体的に例えば、外部光源１２９は、発光ダイオード素子、有機発光ダイオード素子など例示することができる。 The external light source 129 is an element that is arranged outside the housing 110 and emits light that can be detected by the optical sensor 103. Specifically, for example, the external light source 129 can be exemplified by a light emitting diode element, an organic light emitting diode element, and the like.
　導光部材１１９は、筐体１１０の外表面の少なくとも一部を覆い、外部光源１２９が出射した光を筐体１１０の表面およびその近傍に沿って導光する光学部材である。 The light guide member 119 is an optical member that covers at least a part of the outer surface of the housing 110 and guides the light emitted from the external light source 129 along the surface of the housing 110 and the vicinity thereof.
　本実施の形態の場合、導光部材１１９は、光源光到達予想領域１３２を覆うように配置されている。外部光源１２９は、導光部材１１９の端部において筐体１１０の周囲を囲む様に複数個所定の間隔で配置されている。 In the case of the present embodiment, the light guide member 119 is disposed so as to cover the light source light arrival expected region 132. A plurality of external light sources 129 are arranged at predetermined intervals so as to surround the periphery of the housing 110 at the end of the light guide member 119.
　本実施の形態に係る光照射装置１００は、図６に示すように、筐体１１０が破損する場合、筐体１１０に取り付けられている導光部材１１９も同じような箇所が破損する。従って、外部光源１２９から出射する光は、導光部材１１９に導光されるが、破損箇所からは回折や屈折などにより筐体１１０の内部に外光として入射し、光センサ１０３の受光面１３１に到達する。 In the light irradiation apparatus 100 according to the present embodiment, as shown in FIG. 6, when the casing 110 is damaged, the light guide member 119 attached to the casing 110 is also damaged at the same place. Therefore, the light emitted from the external light source 129 is guided to the light guide member 119, but enters the housing 110 as external light from the damaged portion by diffraction, refraction, or the like, and receives the light receiving surface 131 of the optical sensor 103. To reach.
　従って、暗闇や、うす暗い場所で光照射装置１００を使用しても筐体１１０が破損している場合は、光センサ１０３が外光を検出することができ、第１の実施の形態と同様に、光源１０２から所定光量の光２００が出射することを停止、または、出射を不可として、眼に対する安全性を高めることが可能となる。 Therefore, even if the light irradiation device 100 is used in the dark or in a dark place, if the housing 110 is damaged, the optical sensor 103 can detect the external light, which is the same as in the first embodiment. In addition, it is possible to stop the emission of a predetermined amount of light 200 from the light source 102 or to disable the emission, thereby improving the safety for the eyes.
　また、外部光源１２９から出射される光が単色光の場合であって、光センサ１０３が、開口１０１から入射する外光３００と分離して検知することができる場合は以下のように作用する。すなわち、非常に明るい場所で光照射装置１００を使用し、開口１０１から入射する外光３００が光センサ１０３の受光面１３１に到達する場合でも、外部光源１２９に基づく外光を分離して検出することで、高い精度で筐体１１０の破損を検出することが可能となる。 Further, when the light emitted from the external light source 129 is monochromatic light and the optical sensor 103 can detect the light separately from the external light 300 incident from the opening 101, the following effects are obtained. That is, even when the light irradiation device 100 is used in a very bright place and the external light 300 incident from the opening 101 reaches the light receiving surface 131 of the optical sensor 103, the external light based on the external light source 129 is separated and detected. Thus, it is possible to detect the breakage of the housing 110 with high accuracy.
　また、外部光源１２９が所定のパターンで光量などを変化させた場合も、他の外光と分離することができるため上記と同様の効果を得ることができる。 In addition, even when the external light source 129 changes the amount of light in a predetermined pattern, the same effect as described above can be obtained because it can be separated from other external light.
　なお、本発明は、これまで説明した各実施の形態に限定されるものではない。例えば、本明細書において記載した構成要素を任意に組み合わせて、また、構成要素のいくつかを除外して実現される別の実施の形態を本発明の実施の形態としてもよい。また、各実施の形態に対して本発明の主旨、すなわち、請求の範囲に記載される文言が示す意味を逸脱しない範囲で当業者が思いつく各種変形を施して得られる変形例も本発明に含まれる。 The present invention is not limited to the embodiments described so far. For example, another embodiment realized by arbitrarily combining the components described in this specification and excluding some of the components may be used as an embodiment of the present invention. In addition, the present invention includes modifications obtained by making various modifications conceivable by those skilled in the art without departing from the gist of the present invention, that is, the meanings of the words described in the claims. It is.
　例えば、図７に示すように、受光面１３１の角度が異なるように複数の光センサ１０３を仮想的な同心円のそれぞれに配置し、光源光到達予想領域１３２を小さな区画に分割してそれぞれの区画をそれぞれの光センサ１０３に対応させてもよい。この構成により、筐体１１０内部への外光の入射の検知精度を向上させることができ、光照射装置１００の眼に対する安全性を高めることが可能となる。 For example, as shown in FIG. 7, a plurality of optical sensors 103 are arranged in virtual concentric circles so that the angles of the light receiving surface 131 are different, and the light source light arrival prediction area 132 is divided into small sections. May correspond to each optical sensor 103. With this configuration, it is possible to improve the detection accuracy of the incident of external light into the housing 110, and it is possible to improve the safety of the light irradiation device 100 with respect to the eyes.
　また、光センサ１０３は、外光３００を光センサ１０３まで導く受光光学系を備えてもかまわない。受光光学系とは、レンズ、鏡、および、これらの組み合わせなどであり、１つの光センサ１０３でカバーできる範囲よりも広範囲で筐体１１０の破損箇所から侵入する外光３００を光センサ１０３に導くことができる。これにより、筐体１１０の破損箇所を広範囲で検出可能等としつつ、筐体１１０の内方に配置される光センサ１０３の数を抑制することが可能となる。なお、受光光学系を用いた場合、光センサ１０３の受光面１３１とは、受光光学系の受光面となる。 Further, the optical sensor 103 may include a light receiving optical system that guides the external light 300 to the optical sensor 103. The light receiving optical system is a lens, a mirror, a combination thereof, or the like, and guides the external light 300 that enters from a damaged portion of the housing 110 to the optical sensor 103 in a wider range than can be covered by one optical sensor 103. be able to. As a result, it is possible to suppress the number of optical sensors 103 arranged inside the housing 110 while making it possible to detect a damaged portion of the housing 110 in a wide range. When a light receiving optical system is used, the light receiving surface 131 of the optical sensor 103 is a light receiving surface of the light receiving optical system.
　また、第２の実施の形態では、光源光到達予想領域１３２に対応する領域に導光部材１１９を配置したが、導光部材１１９の配置箇所はこれに限定されるものではなく、例えば、開口１０１を除く筐体１１０の外面全体に導光部材１１９を設けてもかまわない。 In the second embodiment, the light guide member 119 is disposed in the region corresponding to the light source light arrival predicted region 132. However, the position where the light guide member 119 is disposed is not limited to this. The light guide member 119 may be provided on the entire outer surface of the housing 110 except for the 101.
　本発明の光照射装置は、脱毛や抑毛のための光や肌質改善のための光などを皮膚に照射する理美容機器や、光を照射して樹脂を硬化させる紫外線照射装置などに利用できる。 The light irradiation device of the present invention is used in hairdressing and beauty equipment that irradiates the skin with light for hair removal and hair suppression, light for skin quality improvement, and ultraviolet irradiation device that cures the resin by irradiating light. it can.
