Description

【0001】
【発明の属する技術分野】
本発明は、皮膚表面から角質を剥がして採取する角質採取シートと、その角質採取シートで採取された角質を撮像する角質撮像方法に関する。
【0002】
【従来の技術】
皮膚の表面は、基底細胞が老化して形成される角質層で覆われており、この角質層から角質を剥がして観察することにより、皮膚の状態を判断することかできる。
このため、コスメティックサロン(化粧品販売店)などでは、顧客の顔の肌の角質を観察することにより、肌の状態を客観的に判断し、その観察結果に基づいてその顧客に最適な化粧品を推奨することとしている。
【0003】
角質を観察する場合は、粘着部が形成された角質採取シートを皮膚に押し当てて剥がすことにより角質を採取し、これを専用の撮像装置で撮像するのが一般的である(特許第3064234号、特許第3143044号、特開平11−309132号公報参照)。
【0004】
図5に示す従来の角質採取シート50は、基材フィルム51Aとカバーフィルム51Bが粘着層52を挟んで接着されると共に、カバーシート51Bに角質採取用粘着部53となる円形の切欠部が形成され、その粘着部53に同形の剥離片54が貼りつけられている。
また、専用の撮像装置55は、撮像ヘッド56に撮像素子57と照明装置58が内蔵されたカメラ59と、角質採取用粘着部53をカメラ59の撮像ヘッド56に対峙させて角質採取シート50を置くことのできるシートホルダ60が形成されたカメラ台61からなる。
【0005】
このシートホルダ60は、エレクトロルミネッセンスのような面状発光体で形成されており、カメラ台61に配されたスイッチ62により、カメラ59の内蔵照明装置58とシートホルダ60を切り換えて択一的に発光させることができるようになっている。
【0006】
そして、角質を撮像するときは、角質採取シート50の剥離片54を剥がして、角質採取用粘着部53を肌に押し当てて角質を採取する。
次いで、その角質採取シート50をカメラ台61のシートホルダ60に載せて、カメラ59をセットし、その撮像ヘッド56とシートホルダ60の間に角質採取シート50を挟みつけて固定した状態で、カメラ59の内蔵照明装置58とシートホルダ60の照明光を選択することにより、採取シート50で採取された角質を反射光及び透過光を選択して観察できる。
【0007】
【発明が解決しようとする課題】
しかしながら、このように透過光と反射光の双方で観察する場合、角質採取シート50は当然のことながら透明であることが要求されるが、保管中に角質採取用粘着部53の裏面側の基材シート51Aがキズついたり取扱中に汚損し、反射光、透過光のいずれで撮像する場合も、キズや汚れがノイズとなるという問題があった。
また、カメラ59の置き方によっては、その撮像ヘッド56と角質採取シート50との間に隙間ができてしまい、外光が撮像されてノイズになってしまうという問題があった。
【0008】
また、化粧品販売店では、比較的小規模のブースで販売しているところでも、角質観察装置の他に、肌用撮像装置などその他の販促用機器を設置しているところが多く、カメラ59とカメラ台61からなる角質観察専用の撮像装置55を設置しようとすると、スペースを別途確保しなければならず、手狭なカウンターがさらに狭くなるという問題があった。
【0009】
そこで本発明は、保管中に基材シートがキズついたり取扱中に汚損しても観測時にノイズを生ずることなく、また、専用の観察装置を用いなくても通常の店舗に多く設置されている肌用撮像装置を用いるだけで角質を観察できるようにすることを技術的課題としている。
【0010】
【課題を解決するための手段】
この課題を解決するために、請求項1に係る角質採取シートは、粘着部で角質を採取した後、内部照明付肌用撮像装置の撮像ヘッドに形成された観察孔を覆うように前記粘着部を貼り付けて使用される角質採取シートであって、不透明な基材フィルムの少なくとも片面に角質採取用粘着部が形成され、その粘着部が前記撮像ヘッドに形成された観察孔を覆う大きさに選定されたことを特徴としている。
【0011】
角質は肌荒れのバロメータであり、採取された角質が大きいほど又は大小混ざって不均一であるほど荒肌であり、小さくて揃っているほど正常な肌であると評価される。
このような観察を行う場合に、発明者の実験によれば、反射光で観察した方が個々の角質の形状を正確に把握できるので評価し易く、透過光では逆光となるために角質が重なっているような場合に個々の角質の形状を観察し難く、また、肌の状態を評価するその他の有益なデータも得られなかった。
【0012】
そこで請求項1の発明では、角質採取シートとして、不透明な基材フィルムに角質採取用粘着部を形成したものを用いて、反射光でのみ角質を観察するようにした。
これにより、保管中や取扱中に基材フィルムの裏面がキズついたり汚損されることがあっても、そのキズや汚れがノイズとして映し出されることがない。
【0013】
そして、請求項2に係る角質撮像方法のように、角質採取シートを皮膚に押し当てて剥がすことにより角質を採取した後、内部照明付肌用撮像装置の撮像ヘッドに形成された観察孔を覆うように角質採取シートの粘着部を貼り付けて肌用撮像装置をオンすれば、採取された角質が内部照明により照射されて、肌を観察するのと同じ要領で角質を観察できるので、肌用観察装置があれば専用の撮像装置も不要になる。
【0014】
この場合に、内部照明付肌用撮像装置の観察孔を覆うように角質採取シートを隙間なく貼り付けることができるので、ノイズとなる外光が遮断されるだけでなく、肌用撮像装置の内部照明の照明光を照射できるので外部の明るさにかかわらず常に同じ条件で角質が撮像される。
【0015】
【発明の実施の形態】
以下、本発明の実施の形態を図面に基づいて具体的に説明する。
図1は本発明に係る角質採取シートを示す説明図、図2は角質採取シートの保管状態を示す説明図,図3は角質撮像方法を示す説明図、図4は角質採取シートの他の実施形態を示す説明図である。
【0016】
図1に示す角質採取シート1は、不透明な基材フィルム2の少なくとも片面に角質採取用粘着部3が形成されてなり、その粘着部3が、内部照明付肌用撮像装置4の撮像ヘッド5に形成された観察孔6に貼付可能な大きさに形成されている。
【0017】
この角質採取シート1は、基材フィルム2として、例えば黒色に着色された厚さ約50μmの遮光性の円形PETフィルムが用いられ、肌用撮像装置4の撮像ヘッド5に形成された観察孔6の直径が10mmである場合に基材フィルム2の直径が15〜20mm程度に形成され、その片面全面に粘着剤が塗付されて角質採取用粘着部3が形成されている。
【0018】
肌用撮像装置4は、ドーム型の撮像ヘッド5内に、その先端に開口形成された直径10mm程度の観察孔6に向って照明光を照射する照明装置7と、観察孔6を肌に押し当てたときにその肌を拡大撮像するためのレンズ8及びCCDなどの撮像素子9が内蔵されている。
【0019】
なお、角質採取シート1…は例えば約10cm×8cmの長方形の剥離紙10に5×4枚ずつ貼り付けられて20枚一組で供給され、一枚一枚剥がしながら使用できるようになっている。
【0020】
そして、角質を撮像する場合は、まず、剥離紙10から角質採取シート1を1枚だけ剥がして(図3(a))、角質を観察しようとする顧客の顔など肌荒れが気になる部分に貼り付けた後、これを剥がすことにより角質を採取する(図3(b))。
【0021】
次いで、その角質採取シート1の角質採取用粘着部3を撮像素子9に対向させて、肌用撮像装置4の観察孔6を覆うように粘着部3の周縁を撮像ヘッド5に貼り付け(図3(c))、肌用撮像装置4をオンすることにより、照明装置7の照明光で粘着部3が照明されて角質が撮像される。
【0022】
この場合に、角質採取シート1は、不透明の基材フィルム2が用いられているので、保管中や取扱中に角質採取シート1の裏面がキズついたり汚損されることがあってもこれがノイズとして撮像されることがない。
【0023】
また、角質採取シート1が、撮像ヘッド5の観察孔6を覆うように隙間なく貼り付けられられて外光が遮断されるので、その外光がノイズとして撮像されることがなく、さらに、肌用撮像装置4の内部照明7の照明光が照射されるので外部の明るさにかかわらず常に同じ条件で角質を撮像することができる。
【0024】
なお、角質採取シート1は円形に限るものではないが、肌用撮像装置4の観察孔6が一般的に円形であることから円形が使いやすい。
また、図4に示すように、円形の粘着部3を形成した角質採取シート1に、つまみとなる耳部11を形成すれば、剥がしたり貼ったりする際の取扱がより便利になる。
さらに、角質採取用粘着部3は基材フィルム2の片面全面に形成されている必要はなく、観察孔6を覆うように貼り付けられる大きさが確保されていれば、基材フィルム2より小さくても良い。
【0025】
【発明の効果】
以上述べたように、本発明に係る角質採取シートによれば、不透明の基材フィルムが用いられているので、保管中や取扱中にキズついたり汚損されることがあってもこれがノイズとして撮像されることがなく、また、内部照明付肌用撮像装置の観察孔を覆うように隙間なく貼り付けられて外光が遮断されるので、外光がノイズとして撮像されることがなく、さらに、肌用撮像装置の内部照明の照明光が照射されるので外部の明るさにかかわらず常に同じ条件で角質を撮像することができるという大変優れた効果を奏する。

BACKGROUND OF THE INVENTION
The present invention relates to a stratum corneum collection sheet that is collected by peeling off the stratum corneum from the skin surface, and a stratum corneum imaging method that images the stratum corneum collected by the stratum corneum collection sheet.
[0002]
[Prior art]
The surface of the skin is covered with a stratum corneum formed by aging of basal cells, and the state of the skin can be determined by detaching the stratum corneum from the stratum corneum and observing it.
For this reason, cosmetic salons (cosmetics stores) etc., objectively judge the skin condition by observing the skin of the customer's face and recommend the best cosmetics for that customer based on the observation results. To do.
[0003]
When observing the stratum corneum, it is common to collect the stratum corneum by pressing the exfoliating sheet on which the adhesive portion is formed against the skin and peeling it off, and image it with a dedicated imaging device (Japanese Patent No. 3064234). No. 3143044, JP-A-11-309132).
[0004]
The conventional keratin collection sheet 50 shown in FIG. 5 has a base film 51A and a cover film 51B bonded to each other with the adhesive layer 52 sandwiched therebetween, and a circular notch that forms the keratin collection adhesive portion 53 is formed on the cover sheet 51B. Then, the same shaped strip 54 is attached to the adhesive portion 53.
Further, the dedicated imaging device 55 includes a camera 59 in which an imaging element 57 and an illumination device 58 are built in the imaging head 56, and a keratin sampling sheet 50 by causing the keratin sampling adhesive portion 53 to face the imaging head 56 of the camera 59. It consists of a camera base 61 on which a seat holder 60 that can be placed is formed.
[0005]
The sheet holder 60 is formed of a planar light-emitting body such as electroluminescence, and the built-in illumination device 58 of the camera 59 and the sheet holder 60 are switched alternatively by a switch 62 disposed on the camera base 61. It can be made to emit light.
[0006]
When the stratum corneum is imaged, the peel piece 54 of the stratum corneum collection sheet 50 is peeled off, and the stratum corneum collection adhesive portion 53 is pressed against the skin to collect the stratum corneum.
Next, the stratum corneum collection sheet 50 is placed on the sheet holder 60 of the camera base 61, the camera 59 is set, and the stratum corneum collection sheet 50 is sandwiched and fixed between the imaging head 56 and the sheet holder 60. By selecting the illumination light of the 59 built-in illumination devices 58 and the sheet holder 60, the stratum corneum collected by the collection sheet 50 can be observed by selecting reflected light and transmitted light.
[0007]
[Problems to be solved by the invention]
However, when observing with both transmitted light and reflected light in this way, the keratin collection sheet 50 is naturally required to be transparent, but the base on the back side of the keratin collection adhesive portion 53 during storage is required. The material sheet 51A is scratched or fouled during handling, and there is a problem that scratches and dirt become noise even when imaging is performed with either reflected light or transmitted light.
Further, depending on how the camera 59 is placed, there is a problem that a gap is formed between the imaging head 56 and the keratin collection sheet 50, and external light is imaged and becomes noise.
[0008]
In addition, in cosmetic stores, where sales are made at a relatively small booth, in addition to the keratin observation device, there are many places where other sales promotion devices such as an imaging device for skin are installed. When trying to install the imaging device 55 dedicated to horny observation comprising the base 61, a space must be secured separately, and there is a problem that a narrow counter is further narrowed.
[0009]
Therefore, the present invention does not cause noise during observation even if the base sheet is scratched during storage or is soiled during handling, and is often installed in ordinary stores without using a dedicated observation device. It is a technical problem to make it possible to observe keratin only by using a skin imaging device.
[0010]
[Means for Solving the Problems]
In order to solve this problem, the keratin collection sheet according to claim 1 is configured such that the keratin collection sheet covers the observation hole formed in the imaging head of the imaging device for skin with internal illumination after the keratin is collected by the adhesion unit. a pasted horny collection sheet used to, at least one side keratin collecting adhesive portion is formed, the size of the adhesive portion covers the saw Sa'ana formed on the imaging head of an opaque substrate film It is characterized by having been selected.
[0011]
The stratum corneum is a barometer for rough skin, and the larger the collected stratum corneum or the larger and smaller the unevenness is, the rougher the skin is.
When performing such observation, according to the inventor's experiment, it is easier to evaluate because the shape of each keratin can be accurately grasped by observing with reflected light, and the keratin overlaps because the transmitted light is backlit. In such cases, it was difficult to observe the shape of individual keratins, and other useful data for evaluating skin condition were not obtained.
[0012]
Therefore, in the first aspect of the present invention, the stratum corneum is observed only by reflected light using a stratum corneum collecting sheet in which a stratum corneum collecting adhesive portion is formed on an opaque base film.
Thus, even if the back surface of the base film is scratched or soiled during storage or handling, the scratch or dirt is not projected as noise.
[0013]
And, like the keratin imaging method according to claim 2, after collecting the keratin by pressing the keratin collection sheet against the skin and peeling it off, the observation hole formed in the imaging head of the imaging device for skin with internal illumination is covered If the skin imaging device is turned on with the adhesive part of the keratin collection sheet attached, the collected keratin is irradiated by internal illumination, and the keratin can be observed in the same way as observing the skin. If there is an observation device, a dedicated imaging device is also unnecessary.
[0014]
In this case, the keratin sampling sheet can be pasted without any gap so as to cover the observation hole of the skin-lighted imaging device with internal illumination. Since the illumination light can be irradiated, the keratin is always imaged under the same conditions regardless of the external brightness.
[0015]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is an explanatory diagram showing a keratin sampling sheet according to the present invention, FIG. 2 is an explanatory diagram showing a storage state of the keratin sampling sheet, FIG. 3 is an explanatory diagram showing a keratin imaging method, and FIG. It is explanatory drawing which shows a form.
[0016]
A stratum corneum collection sheet 1 shown in FIG. 1 has a stratum corneum collecting adhesive part 3 formed on at least one surface of an opaque base film 2, and the adhesive part 3 is an imaging head 5 of a skin imaging device 4 with internal illumination. It is formed in a size that can be attached to the observation hole 6 formed in the above.
[0017]
In this keratin collection sheet 1, for example, a light-shielding circular PET film having a thickness of about 50 μm colored in black is used as the base film 2, and an observation hole 6 formed in the imaging head 5 of the imaging device 4 for skin. When the diameter of the substrate film is 10 mm, the base film 2 is formed to have a diameter of about 15 to 20 mm, and an adhesive is applied to the entire surface of one side to form the keratin sampling adhesive part 3.
[0018]
The skin imaging device 4 has an illumination device 7 that irradiates illumination light toward an observation hole 6 having a diameter of about 10 mm formed in the tip of the dome-shaped imaging head 5 and pushes the observation hole 6 against the skin. A lens 8 and an image sensor 9 such as a CCD for enlarging an image of the skin when it is applied are built in.
[0019]
The exfoliating sheet 1 is attached to a rectangular release paper 10 having a size of about 10 cm × 8 cm, for example, 5 × 4 sheets, supplied as a set of 20 sheets, and can be used while being peeled one by one. .
[0020]
When imaging the stratum corneum, first, only one stratum corneum collection sheet 1 is peeled off from the release paper 10 (FIG. 3A), and a portion of the skin where the rough skin such as the face of the customer who wants to observe the stratum is concerned is concerned. After pasting, the stratum corneum is collected by peeling it off (FIG. 3 (b)).
[0021]
Next, the keratin sampling adhesive part 3 of the keratin sampling sheet 1 is opposed to the image sensor 9, and the periphery of the adhesive part 3 is attached to the imaging head 5 so as to cover the observation hole 6 of the skin imaging device 4 (see FIG. 3 (c)), when the skin imaging device 4 is turned on, the adhesive portion 3 is illuminated with the illumination light of the illumination device 7, and the keratin is imaged.
[0022]
In this case, since the stratum corneum collection sheet 1 uses the opaque base film 2, even if the back surface of the stratum corneum collection sheet 1 is scratched or fouled during storage or handling, this is regarded as noise. No image is taken.
[0023]
Further, since the keratin sampling sheet 1 is stuck without any gap so as to cover the observation hole 6 of the imaging head 5 and the external light is blocked, the external light is not imaged as noise, and further, the skin Since the illumination light of the internal illumination 7 of the imaging device 4 is irradiated, the keratin can always be imaged under the same conditions regardless of the external brightness.
[0024]
Note that the keratin collection sheet 1 is not limited to a circle, but the observation hole 6 of the skin imaging device 4 is generally circular, so that the circle is easy to use.
Moreover, as shown in FIG. 4, if the ear | edge part 11 used as a knob is formed in the keratin collection sheet | seat 1 in which the circular adhesion part 3 was formed, the handling at the time of peeling and sticking will become more convenient.
Further, the stratum corneum collecting adhesive portion 3 does not need to be formed on the entire surface of one side of the base film 2, and is smaller than the base film 2 as long as the size to be attached so as to cover the observation hole 6 is secured. May be.
[0025]
【The invention's effect】
As described above, according to the exfoliating sheet according to the present invention, since an opaque base film is used, even if it is scratched or soiled during storage or handling, this is imaged as noise. In addition, since the external light is blocked by covering the observation hole of the skin-lighted imaging device with internal illumination without gaps, the external light is not imaged as noise. Since the illumination light of the internal illumination of the skin imaging device is irradiated, there is an excellent effect that the keratin can always be imaged under the same conditions regardless of the external brightness.
