SKIN INSPECTION DEVICE

To provide a skin inspection device capable of imaging a wide imaging region on a subject's skin surface using a large image circle and accurately performing imaging from a surface to a deep part of the skin over the whole of the wide imaging region, especially, adapting a depth of field without any focus adjustment to accurately inspect a state of the subject's skin.SOLUTION: A skin inspection device comprises: skin abutting means 1 composed of a cylindrical body for making a tip 11 abut on a subject 100's skin; optical means 2 that is housed in the cylindrical body of the skin abutting means 1, shifts a position of an object side focus 21a to the inside of the tip 11 of the cylindrical body, and is formed using an optical system 21 having a depth of field including the tip 11; and an imaging means 3 that is formed using an imaging element 31 for converting light emitted from the optical means 2 to an electric signal, the imaging element 31 being disposed at an image side focus 21b of the optical system 21.SELECTED DRAWING: Figure 1 【課題】 本発明は、被験者の皮膚表面における広い撮像領域を大きなイメージサークルで撮像し、この広い撮像領域の全体に亘り皮膚の表面から深部までを高精度に撮像でき、特に焦点調節を一切行うことなく被写界深度を適合させることとなり、被験者の皮膚の状態を高精度に検査する皮膚検査装置を提供することを目的とする。【解決手段】 被験者１００の皮膚に先端部１１を当接させる円筒状からなる皮膚当接手段１と、この皮膚当接手段１の円筒状体に収納され、この円筒状体の先端部１１より内側に物体側焦点２１ａの位置を偏移させ、この先端部１１を被写界深度に含む光学系２１で形成される光学手段２と、こお光学手段２から射出される光を電気信号に変換する撮像素子３１で形成され、この撮像素子３１を光学系２１の像側焦点２１ｂに配設してなる撮像手段３とを備える構成である【選択図】 図１
