Abstract
(EN)

PROBLEM TO BE SOLVED: To provide an impersonation detection device that enables visual observation of a scanning position of a document or immediately before (immediately after) the same by receiving light with an optical path inclined to a direction perpendicular to the document.

SOLUTION: In drawing image input means that performs main scanning by receiving reflected scattered light from a document 2 through a lens system to a one-dimensional image sensor, and performs sub-scanning by manually moving a housing 1 that covers the document 2, there are provided the one-dimensional image sensor that is mounted on an upper part of the housing 1 and set such that a light receiving surface thereof is parallel to the drawing, and a lens system that constitutes an optical path surface that is perpendicular to the document 2 and is inclined to a plane including a sensor array direction axis and is orthogonal to the sensor array direction axis are provided. The main scanning is performed at a covered end of the housing 1.

(JA) 【課題】書面に垂直方向に対して傾斜した光路で受光することで、書面の走査位置またはその直前(直後)を常に目視可能とする。
【解決手段】レンズ系を介して書面2からの反射散乱光を1次元イメージセンサに受光することで主走査を行い、書面2を被覆したハウジング1を手送り移動することで副走査を行う図面イメージの入力手段において、該ハウジング1内の上部に装着され、その受光面が図面と平行になるように設定された1次元イメージセンサと、書面2に垂直でセンサ列方向軸を含む平面に対して傾斜し、かつ該センサ列方向軸と直交した光路面を構成するレンズ系とを備え、該ハウジング1の被覆側端部で主走査する。
