樹脂硬化装置Resin curing device
　本発明は、被照射対象物に光を照射する樹脂硬化装置に関する。 The present invention relates to a resin curing device that irradiates light on an object to be irradiated.
　従来から、手や足の指先の爪を装飾するために、ネイルチップやスカルプチュアなどの付け爪を自爪に貼り付けることが一般的に行われている。付け爪には、ウレタンアクリル樹脂などを主成分とするジェルを利用して人工爪を形成するジェルネイルがある。ジェルは、光硬化樹脂の一種であり、紫外線領域の特定波長の光が照射されることで硬化して人工爪となる。そこで、ジェルネイルにおけるジェルを硬化させるために、樹脂硬化装置として、ジェルネイル硬化装置が提案されている（例えば、特許文献１参照）。 Conventionally, in order to decorate nails at the fingertips of hands and toes, it has been common practice to apply nail tips such as nail tips and sculptures to the nails. The artificial nail includes a gel nail that forms an artificial nail using a gel mainly composed of urethane acrylic resin. Gel is a kind of photo-curing resin, which is cured by being irradiated with light of a specific wavelength in the ultraviolet region to form an artificial nail. Then, in order to harden the gel in a gel nail, the gel nail hardening apparatus is proposed as a resin hardening apparatus (for example, refer patent document 1).
　特許文献１に開示されているジェルネイル硬化装置は、配置室形成部材と、発光部などから構成される。配置室形成部材は、手や足（以下、単に「手」と称する）を挿入する挿入口および挿入口から挿入された手を配置する配置室を備える。さらに、配置室形成部材は、配置室を画定する内面上に手を載置する載置台を備える。発光部は、配置室形成部材の配置室に向けてパルス光を発光する。 The gel nail curing device disclosed in Patent Document 1 includes an arrangement chamber forming member, a light emitting unit, and the like. The placement chamber forming member includes an insertion port for inserting a hand or a foot (hereinafter simply referred to as “hand”) and a placement chamber for placing the hand inserted from the insertion port. Further, the arrangement chamber forming member includes a mounting table for placing a hand on an inner surface that defines the arrangement chamber. The light emitting unit emits pulsed light toward the arrangement chamber of the arrangement chamber forming member.
　また、配置室形成部材の配置室は、挿入口を介して外部に開放されている。そのため、配置室の載置台に手を配置した後、発光部からパルス光を配置室内に向けて発光すると、手などが載置されていない載置面で反射する。具体的には、載置台の載置面の色が、例えば白色の場合、パルス光が載置面で反射して、挿入口から外部に漏れることがある。このとき、漏れたパルス光が使用者の視界に入ると、使用者は眩しさを感じる。 Also, the arrangement chamber of the arrangement chamber forming member is opened to the outside through the insertion port. Therefore, after placing a hand on the placement table in the placement chamber and emitting pulsed light from the light emitting unit toward the placement chamber, the hand is reflected on the placement surface on which the hand is not placed. Specifically, when the color of the mounting surface of the mounting table is white, for example, pulsed light may be reflected from the mounting surface and leak outside from the insertion port. At this time, when the leaked pulsed light enters the user's field of view, the user feels dazzling.
　また、発光部のパルス光の発光に伴って、載置面が高温となる。このとき、載置面の周りの空気の温度が、パルス光の周期に従って、周期的に上昇および下降する。これにより、いわゆる光音響効果による騒音が発生する場合がある。その結果、樹脂硬化装置の使用中における静粛性が低下する。 Also, the mounting surface becomes hot as the pulsed light is emitted from the light emitting unit. At this time, the temperature of the air around the mounting surface periodically rises and falls according to the cycle of the pulsed light. Thereby, noise due to a so-called photoacoustic effect may occur. As a result, quietness during use of the resin curing device decreases.
　つまり、従来の樹脂硬化装置においては、上記眩しさや騒音により、使用者に不快感を与えるという課題があった。 In other words, the conventional resin curing device has a problem that the user feels uncomfortable due to the glare and noise.
特開２０１３－２１２３２６号公報JP 2013-212326 A
　本発明は、使用者に不快感を与えにくい樹脂硬化装置を提供する。 The present invention provides a resin curing device that does not cause discomfort to the user.
　つまり、本発明の樹脂硬化装置は、被照射対象物を挿入する挿入口および挿入口から挿入された被照射対象物を配置する配置室を形成した配置室形成部材と、配置室にパルス光を発する発光部と、を備える。配置室形成部材は、被照射対象物を載置する載置台を有する。そして、載置台は、光沢と、黒色系の色彩を有する載置面を備える。 That is, the resin curing device of the present invention includes an insertion port for inserting an object to be irradiated, an arrangement chamber forming member that forms an arrangement chamber for arranging the object to be irradiated inserted from the insertion port, and pulse light to the arrangement chamber. A light emitting unit that emits light. The arrangement chamber forming member has a mounting table on which an object to be irradiated is mounted. The mounting table includes a mounting surface having gloss and black color.
　この構成によれば、発光部は、配置室内にパルス光などの光を発する。このとき、載置面に照射されたパルス光は、黒色系の色彩を有する載置面により、吸収される。これにより、載置面で反射して挿入口から漏れるパルス光の明度が低下する。その結果、使用者に与える眩しさを低減できる。 According to this configuration, the light emitting unit emits light such as pulsed light in the arrangement chamber. At this time, the pulsed light irradiated on the placement surface is absorbed by the placement surface having a black color. As a result, the brightness of the pulsed light that is reflected by the mounting surface and leaks from the insertion port is reduced. As a result, the glare given to the user can be reduced.
　さらに、パルス光などの光が当たる載置面は、光沢を有している。つまり、光沢を有する載置面の表面は、平滑面で形成される。そのため、載置面の表面積は、無光沢である場合（例えば、凹凸を有する粗面）と比べて、光沢を有する載置面の方が小さい。これにより、平滑面で形成される載置面は、吸収する光量を低減する。そのため、吸収される光量による載置面の温度の上昇が抑制される。その結果、載置面に面した空気の温度の上昇による空気の膨張が抑制されると考えられる。 Furthermore, the mounting surface that is exposed to light such as pulsed light is glossy. That is, the surface of the mounting surface having gloss is a smooth surface. Therefore, the surface area of the mounting surface is smaller on the mounting surface having gloss compared to the case where the surface is matte (for example, a rough surface having irregularities). Thereby, the mounting surface formed of a smooth surface reduces the amount of light absorbed. Therefore, an increase in the temperature of the placement surface due to the amount of absorbed light is suppressed. As a result, it is considered that the expansion of the air due to the increase in the temperature of the air facing the mounting surface is suppressed.
　また、載置面上の各点における空気は、パルス光の周期に従って膨張と収縮を繰り返す。そのため、各点において膨張と収縮する空気の領域が、それぞれ重なり合って干渉する。このとき、載置面が粗面で、表面に凹凸がある場合、表面上の各点において、各空気の領域がパルス光から受ける影響にばらつきが生じる。具体的には、各点における空気の領域の膨張と収縮の状態が変化し、空気の領域の互いの重なり具合のばらつきが大きくなる。一方、載置面が平滑面の場合、表面が平坦であるため、各点における空気の領域は、載置面上に一様に存在する。そのため、載置面が粗面の場合に比べて、膨張および収縮する空気の領域の重なり具合のばらつきが生じにくい。つまり、載置面が平滑面の場合、各点における空気の領域の膨張と収縮の調和が保たれる。これにより、パルス光により繰り返される載置面近傍の空気の膨張と収縮の差が小さくなる。そのため、光音響効果による可聴域の空気の振動の発生が低減される。その結果、使用者に対する不快な騒音を抑制される。 Also, the air at each point on the mounting surface repeats expansion and contraction according to the period of the pulsed light. Therefore, the air regions that expand and contract at each point overlap and interfere with each other. At this time, when the mounting surface is rough and the surface is uneven, the influence of each air region on the surface from the pulsed light varies at each point on the surface. Specifically, the state of expansion and contraction of the air region at each point changes, and the variation in the degree of overlap of the air regions increases. On the other hand, when the placement surface is a smooth surface, since the surface is flat, the air region at each point exists uniformly on the placement surface. Therefore, compared with the case where the mounting surface is a rough surface, the variation in the overlapping state of the air regions that expand and contract is less likely to occur. In other words, when the placement surface is a smooth surface, the balance between expansion and contraction of the air region at each point is maintained. Thereby, the difference between the expansion and contraction of the air in the vicinity of the placement surface that is repeated by the pulsed light is reduced. Therefore, the generation of audible air vibration due to the photoacoustic effect is reduced. As a result, unpleasant noise for the user is suppressed.
　つまり、上記構成により、眩しさや騒音の発生を未然に防止して、使用者に不快感を与え難い樹脂硬化装置を実現できる。 That is, with the above-described configuration, it is possible to realize a resin curing device that prevents glare and noise from occurring and hardly discomforts the user.

　図１から図３に示すように、本実施の形態の樹脂硬化装置１は、少なくとも配置室形成部材４と、発光部５と、制御部６と、操作部７などを備える。配置室形成部材４は、被照射対象物を挿入する挿入口２および挿入口２から挿入された被照射対象物を配置する配置室３を有する。発光部５は、配置室３内に向けてパルス光などの光を発する。 As shown in FIGS. 1 to 3, the resin curing device 1 of the present embodiment includes at least a placement chamber forming member 4, a light emitting unit 5, a control unit 6, an operation unit 7, and the like. The arrangement chamber forming member 4 has an insertion port 2 for inserting the irradiation target object and a setting chamber 3 for setting the irradiation target object inserted from the insertion port 2. The light emitting unit 5 emits light such as pulsed light toward the arrangement chamber 3.
　なお、本実施の形態の被照射対象物は、少なくとも光硬化樹脂が塗布された領域を含む部位である。具体的に、被照射対象物は、手や足などの指先である（以下、単に「指先」とも称する）。 In addition, the irradiation target object of this Embodiment is a site | part containing the area | region where the photocuring resin was apply | coated at least. Specifically, the irradiated object is a fingertip such as a hand or a foot (hereinafter also simply referred to as “fingertip”).
　また、以下では、図１に示す挿入口２が形成される配置室形成部材４の壁面（カバー１０）を正面とし、壁面の横方向を幅方向（または並び方向）、壁面の上下方向を高さ方向、装置１の奥行き方向を前後方向として、説明する。 In the following, the wall surface (cover 10) of the arrangement chamber forming member 4 in which the insertion port 2 shown in FIG. 1 is formed is the front surface, the lateral direction of the wall surface is the width direction (or the arrangement direction), and the vertical direction of the wall surface is high. A description will be given assuming that the depth direction of the apparatus 1 is the front-rear direction.
　詳細には、本実施の形態の配置室形成部材４は、略矩形（矩形を含む）の外観を有し、少なくとも挿入口２と、配置室３と、発光部５および制御部６が設けられる光生成室８などから形成される。 Specifically, the arrangement chamber forming member 4 of the present embodiment has a substantially rectangular appearance (including a rectangle), and is provided with at least the insertion port 2, the arrangement chamber 3, the light emitting unit 5, and the control unit 6. It is formed from the light generation chamber 8 or the like.
　さらに、配置室形成部材４は、指先を載置する載置台９と、載置台９に載置された指先を覆うカバー１０とを備える。 Furthermore, the arrangement chamber forming member 4 includes a mounting table 9 on which the fingertip is mounted and a cover 10 that covers the fingertip mounted on the mounting table 9.
　載置台９は、板状の基部１１と、基部１１に立設される一対の壁１２とを備える。基部１１は、平面視において、幅および前後方向に広がる、例えば略矩形（矩形を含む）の板状で構成される。そして、基部１１は、カバー１０とともに配置室３を画定する表面上（内面上）に、発光部５に対向して配置され、指先（被照射対象物）を載置する載置面１３を備えている。 The mounting table 9 includes a plate-like base portion 11 and a pair of walls 12 erected on the base portion 11. The base 11 is configured in a plate shape of, for example, a substantially rectangular shape (including a rectangle) that extends in the width and the front-rear direction in plan view. And the base 11 is provided on the surface (on the inner surface) demarcating the arrangement chamber 3 together with the cover 10 so as to be opposed to the light emitting unit 5 and includes a placement surface 13 on which a fingertip (object to be irradiated) is placed. ing.
　載置面１３は、光沢を有するとともに、黒色系の色彩を有するように構成されている。つまり、載置面１３は、以下で詳細に説明する、波長３１５ｎｍ以上７１５ｎｍ以下のパルス光などの光に対して、鏡面光沢度が８０％以上の面を有している。 The mounting surface 13 is configured to have gloss and black color. That is, the mounting surface 13 has a surface with a specular glossiness of 80% or more with respect to light such as pulsed light having a wavelength of 315 nm or more and 715 nm or less, which will be described in detail below.
　具体的には、載置台９は、例えば黒色のＡＢＳ樹脂の成形で形成され、載置面１３に黒色系の素材を加工した部材を有している。このとき、載置面１３の表面は、例えばバフ研磨などにより鏡面加工されている。これ以外に、載置台９は、例えばポリカーボネート樹脂で形成され、載置面１３に黒色系の塗料を塗装した面で構成してもよい。このとき、黒色系の塗料としては、塗装後に鏡面仕上げとなる塗料を用いる。 Specifically, the mounting table 9 is formed by molding a black ABS resin, for example, and has a member obtained by processing a black material on the mounting surface 13. At this time, the surface of the mounting surface 13 is mirror-finished by, for example, buffing. In addition to this, the mounting table 9 may be formed of, for example, a polycarbonate resin and may be configured by a surface obtained by painting the mounting surface 13 with a black paint. At this time, as the black paint, a paint that has a mirror finish after painting is used.
　基部１１に設けられる一対の壁１２の表面は、照射された光を指先に向けて反射する反射部材を設けて、反射面が形成されている。 The surface of the pair of walls 12 provided in the base 11 is provided with a reflecting member that reflects the irradiated light toward the fingertip, thereby forming a reflecting surface.
　また、載置台９は、カバー１０の挿入口２から取り出し可能に、配置室形成部材４に取り付けられる。これにより、本実施の形態の装置１は、載置台９の着脱によって、手や足を配置する配置スペース（配置領域）の大きさを変更できる。具体的には、載置台９を取り外すことにより、配置スペースを大きくして、例えば足などを配置する。一方、載置台９を取り付けることにより、配置スペースを小さくして、例えば手などを配置する構成とすることができる。 Further, the mounting table 9 is attached to the arrangement chamber forming member 4 so as to be removable from the insertion port 2 of the cover 10. Thereby, the apparatus 1 of this Embodiment can change the magnitude | size of the arrangement | positioning space (arrangement area | region) which arrange | positions a hand and a leg by attachment or detachment of the mounting base 9. FIG. Specifically, by removing the mounting table 9, the arrangement space is increased, for example, a foot or the like is arranged. On the other hand, by mounting the mounting table 9, the arrangement space can be reduced, and for example, a hand can be arranged.
　また、カバー１０は、外部に面する外壁１４と、外壁１４とともに光生成室８を画定する隔壁１５とを備える。これにより、カバー１０は、載置台９とともに配置室３を画定する。そして、カバー１０の外壁１４には、上述したように、正面側の壁面に挿入口２が形成されている。 Further, the cover 10 includes an outer wall 14 that faces the outside, and a partition wall 15 that defines the light generation chamber 8 together with the outer wall 14. Thereby, the cover 10 defines the arrangement chamber 3 together with the mounting table 9. As described above, the insertion wall 2 is formed in the outer wall 14 of the cover 10 on the front wall surface.
　カバー１０の隔壁１５は、一対の側壁１６と、上方壁１７と、後方壁１８とを備える。一対の側壁１６は、図２に示すように、幅方向に間隔を空けて対向して設けられている。上方壁１７は、一対の側壁１６の上端同士を接続するように設けられている。後方壁１８は、一対の側壁１６および上方壁１７の後方側の端部同士を接続するように設けられている。このとき、少なくとも一対の側壁１６の表面は、照射された光を指先に向けて反射する反射部材を設けて、反射面が形成されている。 The partition wall 15 of the cover 10 includes a pair of side walls 16, an upper wall 17, and a rear wall 18. As shown in FIG. 2, the pair of side walls 16 are provided to face each other with an interval in the width direction. The upper wall 17 is provided so as to connect the upper ends of the pair of side walls 16. The rear wall 18 is provided so as to connect the end portions on the rear side of the pair of side walls 16 and the upper wall 17. At this time, at least the surface of the pair of side walls 16 is provided with a reflecting member that reflects the irradiated light toward the fingertip, thereby forming a reflecting surface.
　さらに、隔壁１５の上方壁１７には、発光部５が発するパルス光などの光を通過させる開口を形成している。 Furthermore, an opening through which light such as pulsed light emitted from the light emitting unit 5 passes is formed in the upper wall 17 of the partition wall 15.
　上記構成により、配置室３が、カバー１０の外壁１４の正面側の壁面と、隔壁１５と、載置台９とにより画定される。そして、上述したように、カバー１０の外壁１４の正面側の壁面には、指先の挿入や、載置台９の出し入れが可能な挿入口２が設けられている。このとき、挿入口２は、載置される手よりも大きい載置台９を通過させることができる大きさで形成されている。そして、挿入口２を画定するカバー１０の内周面１０ａと、挿入される手などとの間に、隙間が形成される。 With the above configuration, the arrangement chamber 3 is defined by the wall surface on the front side of the outer wall 14 of the cover 10, the partition wall 15, and the mounting table 9. As described above, the insertion port 2 into which the fingertip can be inserted and the mounting table 9 can be taken in and out is provided on the front wall surface of the outer wall 14 of the cover 10. At this time, the insertion slot 2 is formed in a size that allows the mounting table 9 larger than the mounting hand to pass therethrough. A gap is formed between the inner peripheral surface 10a of the cover 10 that defines the insertion slot 2 and the inserted hand.
　また、光生成室８は、図３に示すように、配置室形成部材４内における配置室３の上方および後方に設けられる。光生成室８には、発光部５と、制御部６が配置される。発光部５は、光生成室８内における配置室３の上方壁１７に面する空間（配置室３の上方の空間）に配置される。そして、発光部５は、配置室３の上方の上方壁１７の開口から配置室３内にパルス光などの光を照射する。制御部６は、光生成室８内における配置室３の後方壁１８に面する空間（配置室３の後方の空間）に配置される。 Further, the light generation chamber 8 is provided above and behind the arrangement chamber 3 in the arrangement chamber forming member 4 as shown in FIG. In the light generation chamber 8, a light emitting unit 5 and a control unit 6 are arranged. The light emitting unit 5 is arranged in a space facing the upper wall 17 of the arrangement chamber 3 in the light generation chamber 8 (space above the arrangement chamber 3). The light emitting unit 5 irradiates the placement chamber 3 with light such as pulsed light from the opening of the upper wall 17 above the placement chamber 3. The control unit 6 is disposed in a space facing the rear wall 18 of the arrangement chamber 3 in the light generation chamber 8 (a space behind the arrangement chamber 3).
　また、発光部５は、フラッシュランプ１９と、反射傘２０と、波長制限フィルタ２１と、保護ガラス２２などを備える。 In addition, the light emitting unit 5 includes a flash lamp 19, a reflector 20, a wavelength limiting filter 21, a protective glass 22, and the like.
　発光部５のフラッシュランプ１９は、紫外線領域から赤外線領域までの広い波長域の光を発光する。これにより、複数種の光硬化樹脂（例えば、ＵＶランプ用の光硬化樹脂、ＵＶＬＥＤ用の光硬化樹脂など）を硬化する。具体的には、フラッシュランプ１９が発する光の波長域には、各光硬化樹脂を硬化する各波長が含まれている。さらに、フラッシュランプ１９は、一方向に延びる、例えば線状光源で構成される。そして、フラッシュランプ１９の長尺方向が、装置１の前後方向と一致するように光生成室８内に、例えば一対配置されている。なお、本実施の形態では、フラッシュランプ１９として、例えばキセノン放電管（閃光放電管）を用いる。これにより、フラッシュランプ１９は、紫外線領域の光としては、ＵＶ―ＡおよびＵＶ－Ｂ領域の光を発光する。ここで、ＵＶ－Ａは波長域が３２０ｎｍ（または３１５ｎｍ）～４００ｎｍの紫外線で、ＵＶ－Ｂは波長域が２８０ｎｍ～３２０ｎｍ（または３１５ｎｍ）の紫外線である。 The flash lamp 19 of the light emitting unit 5 emits light in a wide wavelength range from the ultraviolet region to the infrared region. As a result, a plurality of types of photo-curing resins (for example, a photo-curing resin for UV lamps, a photo-curing resin for UV LEDs, etc.) are cured. Specifically, the wavelength range of the light emitted from the flash lamp 19 includes each wavelength for curing each photocurable resin. Further, the flash lamp 19 is constituted by, for example, a linear light source extending in one direction. For example, a pair of the flash lamps 19 is arranged in the light generation chamber 8 so that the longitudinal direction of the flash lamp 19 coincides with the front-rear direction of the apparatus 1. In the present embodiment, for example, a xenon discharge tube (flash discharge tube) is used as the flash lamp 19. Thus, the flash lamp 19 emits light in the UV-A and UV-B regions as light in the ultraviolet region. Here, UV-A is an ultraviolet ray having a wavelength range of 320 nm (or 315 nm) to 400 nm, and UV-B is an ultraviolet ray having a wavelength range of 280 nm to 320 nm (or 315 nm).
　発光部５の反射傘２０は、フラッシュランプ１９が発した光を配置室３内の指先に向けて反射する。具体的に、反射傘２０は、フラッシュランプ１９の管軸の長尺方向（前後方向）に沿って設けられる。このとき、反射傘２０は、フラッシュランプ１９の長尺方向と直交する断面形状が、光軸を中心線とする放物線状となる形状を有する。 The reflector 20 of the light emitting unit 5 reflects the light emitted from the flash lamp 19 toward the fingertip in the arrangement chamber 3. Specifically, the reflector 20 is provided along the longitudinal direction (front-rear direction) of the tube axis of the flash lamp 19. At this time, the reflector 20 has a shape in which a cross-sectional shape orthogonal to the longitudinal direction of the flash lamp 19 is a parabola with the optical axis as the center line.
　発光部５の波長制限フィルタ２１は、放物線状の反射傘２０の両端で形成される開口部を塞ぐように配置される。波長制限フィルタ２１は、フラッシュランプ１９が発した光を濾波し、ＵＶ－Ａおよび可視光領域の光を選択的に透過させる。つまり、波長制限フィルタ２１は、フラッシュランプ１９が発する光のうち、光硬化樹脂の硬化に寄与しない赤外線領域の光および人体に対する影響の大きいＵＶ－Ｂを遮断する。そして、波長制限フィルタ２１は、光硬化樹脂の硬化に寄与するＵＶ－Ａおよび人体に対する影響の小さい可視光領域の光を透過させる。 The wavelength limiting filter 21 of the light emitting unit 5 is disposed so as to close the opening formed at both ends of the parabolic reflector 20. The wavelength limiting filter 21 filters light emitted from the flash lamp 19 and selectively transmits light in the UV-A and visible light regions. That is, the wavelength limiting filter 21 blocks light in the infrared region that does not contribute to the curing of the photocurable resin and UV-B that has a great influence on the human body, from the light emitted from the flash lamp 19. The wavelength limiting filter 21 transmits UV-A that contributes to the curing of the photocurable resin and light in the visible light region that has a small influence on the human body.
　発光部５の保護ガラス２２は、フラッシュランプ１９が発する光、または波長制限フィルタ２１を透過した光を透過させる。同時に、保護ガラス２２は、配置室３内に挿入された被照射対象物や、配置室３内のゴミや埃などが発光部５の内部に進入するのを防ぐように機能する。 The protective glass 22 of the light emitting unit 5 transmits the light emitted from the flash lamp 19 or the light transmitted through the wavelength limiting filter 21. At the same time, the protective glass 22 functions to prevent an object to be irradiated inserted into the arrangement chamber 3 or dust or dust in the arrangement chamber 3 from entering the light emitting unit 5.
　また、制御部６は、操作部７からの入力に基づいて、発光部５による光の照射を制御する。具体的には、制御部６は、例えば発光部５からの光における波長域の光の総照射エネルギ、１秒当たりの発光回数、発光１回当たりの波長域の光の照射エネルギ、および照射時間などを制御する。 Further, the control unit 6 controls light irradiation by the light emitting unit 5 based on an input from the operation unit 7. Specifically, the control unit 6, for example, the total irradiation energy of light in the wavelength region in the light from the light emitting unit 5, the number of times of light emission per second, the irradiation energy of light in the wavelength region per light emission, and the irradiation time Control etc.
　また、操作部７は、配置室形成部材４の上面に設けられ、各種のスイッチや、表示ランプなどを備える。そして、操作部７は、制御部６への入力、および入力情報などの表示を行う。 The operation unit 7 is provided on the upper surface of the arrangement chamber forming member 4 and includes various switches, a display lamp, and the like. Then, the operation unit 7 displays the input to the control unit 6 and the input information.
　以上のように、本実施の形態の樹脂硬化装置１が構成される。 As described above, the resin curing device 1 of the present embodiment is configured.
　以下に、本実施の形態の樹脂硬化装置１の動作および作用について、説明する。 Hereinafter, the operation and action of the resin curing device 1 of the present embodiment will be described.
　まず、配置室形成部材４の挿入口２から、各爪にジェルネイルなどの光硬化樹脂を塗布した状態の手などの指先を挿入する。このとき、手の爪に塗布された光硬化樹脂を硬化させる場合、載置台９を配置室形成部材４に取り付ける。載置台９を配置した状態で、手の指先を配置室３の挿入口２から配置室３内に挿入する。そして、載置台９の載置面１３上に、手の指先を載置する。 First, a fingertip such as a hand in a state where a photo-curing resin such as gel nail is applied to each nail is inserted from the insertion port 2 of the arrangement chamber forming member 4. At this time, when the photo-curing resin applied to the nail of the hand is cured, the mounting table 9 is attached to the arrangement chamber forming member 4. With the mounting table 9 arranged, the fingertip of the hand is inserted into the arrangement chamber 3 from the insertion port 2 of the arrangement chamber 3. Then, the fingertip of the hand is placed on the placement surface 13 of the placement table 9.
　つぎに、使用者は、操作部７のスイッチなどを操作し、制御部６を介して発光部５を制御し発光させる。具体的には、発光部５のフラッシュランプ１９により、パルス光を発光する。発光されたパルス光は、発光部５の反射傘２０により、配置室３に配置された指先の爪に向かって照射される。このとき、パルス光は、波長制限フィルタ２１を透過した光である。そのため、パルス光は、赤外線領域の光およびＵＶ－Ｂを含まず、光硬化樹脂の硬化に寄与するＵＶ－Ａおよび人体に対する影響の小さい可視光領域の光が、爪に照射される。 Next, the user operates the switch of the operation unit 7 to control the light emitting unit 5 through the control unit 6 to emit light. Specifically, the flash lamp 19 of the light emitting unit 5 emits pulsed light. The emitted pulsed light is irradiated toward the nail of the fingertip arranged in the arrangement chamber 3 by the reflector 20 of the light emitting unit 5. At this time, the pulsed light is light that has passed through the wavelength limiting filter 21. Therefore, the pulsed light does not contain light in the infrared region and UV-B, and the nail is irradiated with UV-A that contributes to the curing of the photocurable resin and light in the visible light region that has little influence on the human body.
　以上の動作により、各爪に塗布されたジェルネイルなどの光硬化樹脂が硬化する。 By the above operation, the photo-curing resin such as gel nail applied to each nail is cured.
　以下に、本実施の形態のポイントである載置面を構成する、具体的な試料に基づいて、光沢度、反射率および騒音について、図４を参照しながら説明する。 Hereinafter, glossiness, reflectance, and noise will be described with reference to FIG. 4 based on specific samples constituting the mounting surface, which is the point of the present embodiment.
　まず、載置面を構成する試料の光沢度について、以下の７つの異なる条件で作製した試料に基づいて、検討評価した。 First, the glossiness of the sample constituting the mounting surface was evaluated based on samples prepared under the following seven different conditions.
　異なる条件で作製した７つの試料は、以下の通りである。 Seven samples prepared under different conditions are as follows.
　第１試料は、ポリカーボネート樹脂（ＰＣ板）を黒色に塗装し、光沢を有さない試料である。第２試料は、第１試料を塗装する前のポリカーボネート樹脂（ＰＣ板）で、白色の試料である。第３試料は、反射シート用材料（メタルミー（登録商標）７５ＴＳ）で形成し、高い光沢を有する試料である。第４試料は、黒色のポリカーボネート樹脂（ＰＣ）で、光沢仕上げされ、光沢を有する試料である。第５試料は、アルミテープで形成し、光沢を有する試料である。第６試料は、黒色のＡＢＳ樹脂（厚さ３ｍｍ）の成形で形成し、成形時に鏡面仕上げされ、光沢を有する試料である。第７試料は、黒色に塗装したＡＢＳ樹脂（厚さ３ｍｍ）で成形して形成し、光沢を有さない試料である。 The first sample is a sample in which polycarbonate resin (PC board) is painted black and does not have gloss. The second sample is a polycarbonate resin (PC plate) before coating the first sample, and is a white sample. The third sample is a sample formed of a reflective sheet material (Metal Me (registered trademark) 75TS) and having high gloss. The fourth sample is a glossy finished sample made of black polycarbonate resin (PC). The fifth sample is a sample formed with aluminum tape and having gloss. The sixth sample is a sample that is formed by molding a black ABS resin (thickness 3 mm), is mirror-finished at the time of molding, and has a gloss. The seventh sample is a sample which is formed by molding with black painted ABS resin (thickness 3 mm) and has no gloss.
　上記の条件で作製した各試料の鏡面光沢度を、光沢計（堀場製作所製のグロスチェッカーＩＧ－３３１）を用い、ＪＩＳ　Ｚ８７４１：１９９７（ＩＳＯ　２８１３：１９９４に相当）「鏡面光沢度‐測定方法」に基づいて測定した。このとき、入射角は、一般測定用の６０°で測定した。 Using a gloss meter (Gloss Checker IG-331 manufactured by HORIBA, Ltd.), JIS Z8741: 1997 (equivalent to ISO 2813: 1994) “Specular Gloss—Measurement Method” Measured based on At this time, the incident angle was measured at 60 ° for general measurement.
　なお、上記ＪＩＳ規格に従うと、鏡面光沢度は、可視波長範囲の全域にわたって屈折率ｎ＝１．５６７であるガラス表面の光の入射角６０度における鏡面反射率を１００％の基準として、同条件における試料面の鏡面反射率との比率で表したものと定義される。 According to the above JIS standard, the specular glossiness is the same as that with the specular reflectance at a light incident angle of 60 degrees on the glass surface having a refractive index n = 1.567 over the entire visible wavelength range as a reference of 100%. Is defined as a ratio to the specular reflectance of the sample surface.
　以下に、各試料の鏡面光沢度の測定結果を、（表１）に示す。 The measurement results of the specular gloss of each sample are shown below (Table 1).
Figure JPOXMLDOC01-appb-T000001
Figure JPOXMLDOC01-appb-T000001
　（表１）に示すように、第２試料から第６試料の鏡面光沢度は、８０％以上であった。一方、第１試料および第７試料の鏡面光沢度は、８０％以下であった。 As shown in (Table 1), the specular gloss of the second sample to the sixth sample was 80% or more. On the other hand, the specular glossiness of the first sample and the seventh sample was 80% or less.
　なお、鏡面光沢度の測定結果が１００より高い第３試料、第５試料については、入射角を高光沢用の２０°でも計測した。しかし、鏡面光沢度の測定結果は、入射角６０°と同様に、ＯＶＥＲで示すように１００を超えた。 In addition, about the 3rd sample and the 5th sample whose measurement result of mirror surface glossiness is higher than 100, the incident angle was also measured at 20 ° for high gloss. However, the measurement result of the specular glossiness exceeded 100 as shown by OVER, similarly to the incident angle of 60 °.
　つぎに、上記の条件で作製した各試料の全光線反射率を、分光光度計（日立ハイテクノロジーズ製のＵ－４０００）を用いて測定した。 Next, the total light reflectance of each sample prepared under the above conditions was measured using a spectrophotometer (U-4000 manufactured by Hitachi High-Technologies).
　以下に、各試料の全光線反射率の測定結果を、図４および（表２）に示す。なお、図４においては、各試料の反射率を、第１試料から順に、符号ａ（第１試料）、ｂ（第２試料）、ｃ（第３試料）、ｄ（第４試料）、ｅ（第５試料）、ｆ（第６試料）、ｇ（第７試料）で示している。また、（表２）は、波長３１５ｎｍ以上７５０ｎｍ以下における各試料の全光線反射率を示している。 The measurement results of the total light reflectance of each sample are shown in FIG. 4 and (Table 2) below. In FIG. 4, the reflectance of each sample is shown in order from the first sample: a (first sample), b (second sample), c (third sample), d (fourth sample), e (Fifth sample), f (sixth sample), and g (seventh sample). Moreover, (Table 2) has shown the total light reflectivity of each sample in wavelength 315nm or more and 750nm or less.
Figure JPOXMLDOC01-appb-T000002
Figure JPOXMLDOC01-appb-T000002
　（表２）に示すように、第１試料、第４試料、第６試料、第７試料は、反射率が１０％以下と、低い結果が得られた。一方、第２試料、第３試料、および第５試料は、反射率が１０％以上であった。そのため、第２試料、第３試料、および第５試料を載置面に形成した場合、使用者が眩しさを感じる程度の光が、挿入口２から漏れるおそれが高いと考えられる。 As shown in Table 2, the first sample, the fourth sample, the sixth sample, and the seventh sample had a low reflectance of 10% or less. On the other hand, the reflectivity of the second sample, the third sample, and the fifth sample was 10% or more. Therefore, when the 2nd sample, the 3rd sample, and the 5th sample are formed in a mounting surface, it is thought that there is a high possibility that light of the extent which a user will feel dazzle may leak from insertion slot 2.
　つぎに、上記の条件で作製した各試料の騒音を、騒音測定器（ＲＩＯＮ製のＳＡ－２９）を用いて、以下の測定条件で測定した。 Next, the noise of each sample produced under the above conditions was measured under the following measurement conditions using a noise measuring instrument (SA-29 manufactured by RION).
　まず、騒音測定に用いた樹脂硬化装置は、反射傘内に１つのキセノン放電管を配置した発光部５と、透過光を３１５ｎｍ～７５０ｎｍ程度の波長に濾波する波長制限フィルタ２１とを備えている。発光部５は、各試料の真上からパルス光を照射する。このとき、各試料に照射した光、つまり波長制限フィルタ２１である色ガラスと保護ガラス２２を透過した光の分光エネルギの分布を、大塚電子製のＭＣＰＤ３０００で測定し、図４に符号ｈで示している。 First, the resin curing device used for noise measurement includes a light emitting unit 5 in which one xenon discharge tube is arranged in a reflector and a wavelength limiting filter 21 that filters transmitted light to a wavelength of about 315 nm to 750 nm. . The light emitting unit 5 emits pulsed light from directly above each sample. At this time, the spectral energy distribution of the light irradiated to each sample, that is, the light transmitted through the color glass and the protective glass 22 serving as the wavelength limiting filter 21, was measured with an MCPD 3000 manufactured by Otsuka Electronics, and indicated by symbol h in FIG. ing.
　発光部５の発光条件として、発光周波数を５０Ｈｚ、閃光時間を１１０μｓに設定した。また、発光部５は、各試料に、５秒間照射後、２秒間休止（冷却）のサイクル条件で、８サイクル（総計５６秒）行った。 As the light emission conditions of the light emitting unit 5, the light emission frequency was set to 50 Hz and the flash time was set to 110 μs. In addition, the light emitting unit 5 was subjected to 8 cycles (total 56 seconds) under the cycle condition of irradiation (cooling) for 2 seconds after irradiating each sample for 5 seconds.
　そして、各試料の騒音を、パルス光の照射時間内において、照射開始１５秒後から２５秒後までの間の１０秒間で測定し、その最大値を記録した。このとき、外部からの雑音の影響を受けないように、遮音された暗箱内に樹脂硬化装置を設置して、測定した。 Then, the noise of each sample was measured within 10 seconds from the start of irradiation to 15 seconds after irradiation within the pulsed light irradiation time, and the maximum value was recorded. At this time, measurement was performed by installing a resin curing device in a sound-insulated dark box so as not to be affected by external noise.
　以下に、各試料の騒音の測定結果を、（表３）に示す。 The measurement results of noise of each sample are shown in (Table 3) below.
Figure JPOXMLDOC01-appb-T000003
Figure JPOXMLDOC01-appb-T000003
　（表３）に示すように、同じ材質および形状で、反射率が同程度の試料でも、鏡面光沢度が高い試料は、鏡面光沢度が低い試料よりも騒音値が下がる傾向があることが判った。 As shown in (Table 3), even with samples of the same material and shape and the same reflectivity, samples with high specular gloss tend to have lower noise values than samples with low specular gloss. It was.
　例えば、同じポリカーボネート樹脂製で黒色に塗装している第１試料と第２試料とを比べると、（表２）および（表３）の結果より、鏡面光沢度の低い第１試料の騒音値が７８．３ｄＢに対し、鏡面光沢度の高い第２試料の騒音値は７１．４ｄＢであった。つまり、第２試料の騒音値は、第１試料の騒音値よりも、６．９ｄＢ低かった。そして、第２試料から発生する音（騒音）は、第１試料から発生する音（騒音）よりも低く、人間の官能的に判断しても静かであった。 For example, when comparing the first sample made of the same polycarbonate resin and painted in black, the noise value of the first sample having a low specular gloss is found from the results of (Table 2) and (Table 3). In contrast to 78.3 dB, the noise value of the second sample having a high specular gloss was 71.4 dB. That is, the noise value of the second sample was 6.9 dB lower than the noise value of the first sample. The sound (noise) generated from the second sample was lower than the sound (noise) generated from the first sample, and was quiet even when judged by human sensuality.
　また、同じ黒色のＡＢＳ樹脂の第６試料と第７試料とを比べると、（表２）と（表３）の結果より、鏡面光沢度の低い第７試料の騒音値が８１．３ｄＢに対し、鏡面光沢度の高い第６試料の騒音値は７５．１ｄＢであった。つまり、第６試料の騒音値は、第７試料の騒音値よりも６．２ｄＢ低かった。そして、第６試料から発生する音（騒音）は、第７試料から発生する音（騒音）よりも低く、第１試料の騒音値は、静かであった。 Further, when comparing the sixth sample and the seventh sample of the same black ABS resin, the noise value of the seventh sample having a low specular gloss is 81.3 dB from the results of (Table 2) and (Table 3). The noise value of the sixth sample having a high specular gloss was 75.1 dB. That is, the noise value of the sixth sample was 6.2 dB lower than the noise value of the seventh sample. The sound (noise) generated from the sixth sample was lower than the sound (noise) generated from the seventh sample, and the noise value of the first sample was quiet.
　上記の各試料による検討結果によれば、載置台９の載置面１３を黒色系の色彩で構成すると、発光部５が発光したパルス光は黒色系の載置面１３で吸収される。これにより、載置面１３から反射して、挿入口２から漏れるパルス光の明度が低下する。その結果、使用者に与える眩しさを低減することができる。 According to the examination results of each sample described above, when the mounting surface 13 of the mounting table 9 is configured with a black color, the pulsed light emitted from the light emitting unit 5 is absorbed by the black mounting surface 13. Thereby, the brightness of the pulsed light reflected from the placement surface 13 and leaking from the insertion port 2 is lowered. As a result, the glare given to the user can be reduced.
　しかし、上述したように、パルス光が、黒色系の色彩で、かつ粗面の載置面１３に照射された場合、各空気の領域の膨張や収縮のばらつきにより、騒音が発生する。 However, as described above, when the pulsed light is irradiated on the mounting surface 13 having a black color and a rough surface, noise is generated due to variations in expansion and contraction of each air region.
　つまり、発光部５が発光するパルス光が、黒色系の色彩を有する載置面１３に断続的に当たると、多くのパルス光が載置面１３で吸収される。その結果、載置面１３の温度が上昇する。そして、載置面１３に面した空気の温度が上昇し、空気が膨張する。 That is, when the pulsed light emitted from the light emitting unit 5 intermittently hits the mounting surface 13 having a black color, a lot of pulsed light is absorbed by the mounting surface 13. As a result, the temperature of the mounting surface 13 increases. And the temperature of the air which faced the mounting surface 13 rises, and air expand | swells.
　一方、パルス光が載置面１３に当たっていない場合、温度の上昇した載置面１３の温度が低下する。そして、載置面１３に面した空気が冷めて、空気の温度が低下し、空気が収縮する。 On the other hand, when the pulsed light is not hitting the mounting surface 13, the temperature of the mounting surface 13 whose temperature has increased decreases. And the air which faced the mounting surface 13 cools, the temperature of air falls, and air contracts.
　これにより、パルス光の発光周期で、空気の膨張と収縮が繰り返される。その結果、空気に振動が生じ、光音響効果による音響波が発生する。このとき、音響波による空気の振動が人間の可聴域に達すると、騒音として感知されると、本願の発明者は考えた。 This causes the air to repeat the expansion and contraction in the pulse light emission cycle. As a result, vibration is generated in the air, and an acoustic wave is generated by the photoacoustic effect. At this time, the inventors of the present application considered that when the vibration of the air due to the acoustic wave reaches the human audible range, it is detected as noise.
　そこで、本願の発明者は、黒色系の色彩を有する載置面１３において、載置面１３の表面を高い光沢を有する鏡面とすることにより、この騒音が低減すると考えて、上記のような試料で検討した。その結果、（表３）の結果に示したように、騒音が低減することを確認した。 In view of this, the inventor of the present application considers that the noise is reduced by setting the surface of the mounting surface 13 to be a mirror surface having high glossiness in the mounting surface 13 having a black color, and thus the sample as described above. I examined it. As a result, as shown in the results of (Table 3), it was confirmed that noise was reduced.
　そして、本願の発明者は、騒音が低減するメカニズムについて、さらに検討した。 And the inventor of the present application further examined the mechanism for reducing noise.
　まず、パルス光が載置面１３に照射されているとき、本実施の形態の載置面１３は、載置面１３の表面の（微視的な）形状は、凹凸の少ない平滑面で、かつ高い光沢を備えている。そのため、載置面１３の表面積は、無光沢である場合（載置面１３の表面に凹凸を有する粗面）と比べて、小さい。そして、表面積が小さく、平滑面を有する載置面１３は、吸収される光量が低減される。これにより、載置面１３の温度が上昇しにくくなる。その結果、載置面１３に面した空気の温度の上昇が抑制され、空気が膨張しにくくなる。 First, when the mounting surface 13 is irradiated with pulsed light, the mounting surface 13 of the present embodiment has a (microscopic) shape of the surface of the mounting surface 13 that is a smooth surface with less unevenness. And it has a high gloss. For this reason, the surface area of the mounting surface 13 is smaller than when it is matte (a rough surface having irregularities on the surface of the mounting surface 13). Further, the amount of light absorbed by the mounting surface 13 having a small surface area and a smooth surface is reduced. Thereby, the temperature of the mounting surface 13 becomes difficult to rise. As a result, an increase in the temperature of the air facing the placement surface 13 is suppressed and the air is less likely to expand.
　また、載置面１３上の各点における空気は、膨張と収縮を繰り返しており、各点における空気の領域のそれぞれが互いに重なり合って干渉している。このとき、載置面１３が粗面であれば、表面の凹凸により、各点における各空気の領域のパルス光から受ける影響がばらつく。そのため、各点の空気の領域における、空気の膨張と収縮の具合（状態）が変化する。これにより、膨張・収縮する各空気の領域の互いの重なり具合のばらつきが大きくなる。その結果、騒音が発生しやすい。 Further, the air at each point on the placement surface 13 repeats expansion and contraction, and the air regions at each point overlap each other and interfere with each other. At this time, if the mounting surface 13 is a rough surface, the influence received from the pulsed light in each air region at each point varies due to the unevenness of the surface. Therefore, the degree (state) of air expansion and contraction in the air region at each point changes. Thereby, the dispersion | variation in the mutual overlap condition of the area | region of each air which expand | swells and shrink | contracts becomes large. As a result, noise is likely to occur.
　一方、本実施の形態の載置面１３は、表面が平坦な平滑面で形成する。そのため、膨張・収縮する各点の空気の領域は、載置面１３上に一様に形成される。これにより、膨張・収縮する各空気の領域の重なり具合におけるばらつきが生じにくい。つまり、各点における空気の領域における膨張と収縮に調和が保たれる。これにより、パルス光により繰り返される載置面１３近傍の空気の膨張と収縮の差が小さくなる。その結果、空気の振動が低減されて、人間の可聴域に達する騒音の発生が抑制される。 On the other hand, the mounting surface 13 of the present embodiment is formed of a smooth surface having a flat surface. Therefore, the air region at each point that expands and contracts is uniformly formed on the mounting surface 13. As a result, it is difficult for variations in the overlapping state of the air regions to expand and contract. That is, harmony is maintained with expansion and contraction in the air region at each point. Thereby, the difference between the expansion and contraction of the air in the vicinity of the mounting surface 13 that is repeated by the pulsed light is reduced. As a result, the vibration of air is reduced and the generation of noise reaching the human audible range is suppressed.
　上記のように、載置面１３を黒色系の色彩で、かつ高い光沢を有する載置面とすることにより、眩しさや騒音の発生を抑制して、使用者の不快感を低減することができる。 As described above, by setting the placement surface 13 to a placement surface having a black color and high gloss, it is possible to suppress the occurrence of glare and noise and reduce the user's discomfort. .
　以上で説明したように、本発明の樹脂硬化装置は、被照射対象物を挿入する挿入口および挿入口から挿入された被照射対象物を配置する配置室を形成した配置室形成部材と、配置室にパルス光を発する発光部と、を備える。配置室形成部材は、被照射対象物を載置する載置台を有する。そして、載置台は、光沢と、黒色系の色彩を有する載置面を備える。 As described above, the resin curing device of the present invention includes an arrangement chamber forming member that forms an insertion port for inserting an object to be irradiated and an arrangement chamber for arranging the object to be irradiated inserted from the insertion port. A light emitting unit that emits pulsed light to the chamber. The arrangement chamber forming member has a mounting table on which an object to be irradiated is mounted. The mounting table includes a mounting surface having gloss and black color.
　また、本発明の樹脂硬化装置は、載置面が、波長３１５ｎｍ以上７１５ｎｍ以下のパルス光に対して全光線反射率が１０％以下で、鏡面光沢度が８０％以上であればよい。 Further, in the resin curing device of the present invention, the mounting surface only needs to have a total light reflectance of 10% or less and a specular gloss of 80% or more with respect to pulsed light having a wavelength of 315 nm to 715 nm.
　また、本発明の樹脂硬化装置は、載置面を、黒色の塗料を塗装したポリカーボネート樹脂または黒色のＡＢＳ樹脂で形成してもよい。 Further, in the resin curing device of the present invention, the mounting surface may be formed of a polycarbonate resin coated with a black paint or a black ABS resin.
　これらの構成によれば、載置面１３は、黒色系の色彩を有する塗料で塗装したポリカーボネート樹脂または黒色のＡＢＳ樹脂で形成される。さらに、載置面１３は、波長３１５ｎｍ以上７１５ｎｍ以下のパルス光に対して全光線反射率が１０％以下で、かつ鏡面光沢度が８０％以上の面で構成される。これにより、載置面１３が、微視的に平滑面となる。そのため、載置面１３が、パルス光を吸収しやすい黒色系の色彩を有する面でも、膨張収縮する空気の領域のアンバランスを防止する。これにより、パルス光が当たった載置面１３近傍の空気が振動しにくくなる。つまり、騒音の発生が効果的に抑制される。その結果、眩しさや騒音の発生を抑制して、使用者の不快感を低減する、使い勝手に優れた樹脂硬化装置を実現できる。 According to these configurations, the mounting surface 13 is formed of a polycarbonate resin or a black ABS resin painted with a paint having a black color. Further, the mounting surface 13 is configured by a surface having a total light reflectance of 10% or less and a specular gloss of 80% or more with respect to pulsed light having a wavelength of 315 nm or more and 715 nm or less. Thereby, the mounting surface 13 becomes a microscopically smooth surface. Therefore, even when the mounting surface 13 has a black color that easily absorbs pulsed light, unbalance of the air region that expands and contracts is prevented. Thereby, the air in the vicinity of the mounting surface 13 struck by the pulsed light is less likely to vibrate. That is, the generation of noise is effectively suppressed. As a result, it is possible to realize an easy-to-use resin curing device that suppresses glare and noise and reduces user discomfort.
　なお、本実施の形態の樹脂硬化装置は、上記実施の形態に限定されるものではなく、本発明の要旨を逸脱しない範囲内において種々変更を加えることができることはいうまでもない。 It should be noted that the resin curing device of the present embodiment is not limited to the above-described embodiment, and it goes without saying that various changes can be made without departing from the gist of the present invention.
　具体的には、上記実施の形態では、配置室３に被照射対象物として人間の手の指先を挿入してパルス光を照射する構成を例に説明したが、これに限られない。例えば、配置室に人間の足の指先を挿入して、パルス光を照射する構成としてもよい。さらに、配置室に人間以外の動物の手や足の指先を挿入して、パルス光を照射する構成としてもよい。つまり、被照射対象物としては、人間や動物でもよく、さらに光硬化樹脂を塗布し、パルス光で硬化できるものであれば任意でよい。 Specifically, in the above-described embodiment, the configuration in which the fingertip of a human hand is inserted into the placement chamber 3 as an irradiation target and irradiated with pulsed light has been described as an example, but the present invention is not limited thereto. For example, a configuration may be adopted in which a fingertip of a human foot is inserted into the placement chamber and pulsed light is irradiated. Furthermore, it is good also as a structure which inserts the hand of a non-human animal and the fingertip of a non-human animal, and irradiates pulsed light. That is, the object to be irradiated may be a human being or an animal, and may be arbitrary as long as it can be further coated with a photocurable resin and cured with pulsed light.
　また、上記実施の形態では、発光部５の光源として、一対のフラッシュランプ１９で構成した例で説明したが、これに限られない。例えば、一つ以上のフラッシュランプ１９を備える構成であれば、具体的な数は限定されない。 In the above embodiment, the light source of the light emitting unit 5 is described as an example of a pair of flash lamps 19, but is not limited thereto. For example, the specific number is not limited as long as it includes one or more flash lamps 19.
　また、上記実施の形態では、載置面１３を有する載置台９が、配置室形成部材４のカバー１０から着脱自在な構成を例に説明したが、これに限られない。例えば、載置台をカバー１０に固定して底部としてもよい。つまり、配置室形成部材を筐体で構成してもよい。 In the above embodiment, the mounting table 9 having the mounting surface 13 is described as being detachable from the cover 10 of the arrangement chamber forming member 4 as an example. However, the present invention is not limited to this. For example, the mounting table may be fixed to the cover 10 as the bottom. That is, the arrangement chamber forming member may be constituted by a housing.
　また、上記実施の形態では、載置台９の基部１１の載置面１３のみが黒色系の色彩を有するとともに、光沢を有する構成を例に説明したが、これに限られない。例えば、載置台９の壁１２や、隔壁１５の側壁１６、上方壁１７または後方壁１８などに黒色系の色彩を施すとともに、光沢を有する構成としてもよい。これにより、実施の形態と同様の効果を、より高めることができる。 In the above embodiment, only the mounting surface 13 of the base 11 of the mounting table 9 has the black color and the glossy structure as an example. However, the present invention is not limited to this. For example, the wall 12 of the mounting table 9, the side wall 16, the upper wall 17, or the rear wall 18 of the partition wall 15 may be given a black color and may have a glossy structure. Thereby, the effect similar to embodiment can be heightened more.
　本発明は、使用中において、使用者に不快な眩しさや騒音の低減が要望される被照射対象物に光を照射する樹脂硬化装置などの用途に適用できる。 The present invention can be applied to applications such as a resin curing device that irradiates light on an object to be irradiated, which is required to reduce unpleasant glare and noise during use.
