PROBLEM TO BE SOLVED: To embody an imaging device capable of positioning with ease in a non-contact manner and without the use of image processing.SOLUTION: An imaging device comprises an imaging part (2) for imaging a hand (1), a first group of visible light sources (6) for emitting two rays of visible light, and a specular surface (4) for reflecting the hand (1). The distance between the hand (1) and the imaging part (2) is the appropriate distance for the imaging part (2) to image the hand (1) when intersection points where each of the two rays of visible light intersects the hand (1) overlap each other.SELECTED DRAWING: Figure 5COPYRIGHT: (C)2018,JPO&INPIT【課題】非接触かつ画像処理不要に、位置合わせが容易に可能な撮像装置を実現する。【解決手段】手(1)を撮像する撮像部(2)と、2本の可視光線を出射する可視光源第1群(6)と、手(1)を映す鏡面部(4)と、を備える。手(1)と撮像部(2)との間の距離は、2本の可視光線の各々が手(1)と交わる交点が、互いに重なり合うとき、撮像部(2)が手(1)を撮像するのに適した距離である。【選択図】図5
