Title (EN) IMAGE SCANNING UNIT
(FR) APPAREIL NUMÉRISEUR D'IMAGE
(JA) 画像読取ユニット
Abstract:
(EN) Provided is an image scanning unit which makes it possible to improve scanning accuracy while also making the overall body thinner by appropriately positioning a plurality of reflection members within an effective space in a carriage frame without wasting space. An image scanning unit, wherein a frame is divided into at least two spaces facing an irradiation surface, a first accommodation unit for accommodating a light source unit is formed in one of the spaces, a second accommodation unit for accommodating at least one reflection member is formed in the other adjacent space, a first reflection member for initially receiving light reflected from the irradiation surface is positioned at the side opposite the irradiation surface with the first accommodation unit positioned therebetween, and a light-shielding member is provided between the first reflection member and the reflection member positioned in the other space and prevents light that has strayed from a scanning light path from the first reflection member from being incident on the reflection member in the other space.
(FR) L'invention concerne un appareil numériseur d'image offrant une précision d'analyse accrue dans un corps général aminci grâce à un positionnement adéquat d'une pluralité d'éléments réfléchissants dans un espace efficace d'une armature de chariot sans perte de place. L'appareil numériseur d'image comprend une armature divisée en au moins deux espaces en regard d'une surface exposée à un rayonnement. Une première unité d'accueil destinée à accueillir une unité source de lumière est ménagée dans l'un des espaces. Une deuxième unité d'accueil destinée à accueillir au moins un élément réfléchissant est ménagée dans l'autre espace adjacent. Un premier élément réfléchissant destiné à recevoir initialement la lumière réfléchie par la surface exposée à un rayonnement est positionné du côté opposé à celle-ci et séparé de celle-ci par la première unité d'accueil. Un élément bloquant la lumière est placé entre le premier élément réfléchissant et l'élément réfléchissant positionné dans l'autre espace de manière à empêcher la lumière parasite issue d'un trajet de lumière d'analyse provenant du premier élément réfléchissant de venir frapper l'élément réfléchissant dans l'autre espace.
(JA)  複数の反射部材をキャリッジフレームの有効スペース内に無駄なく適正に配置することによって、全体の薄型化を図ると共に、読取精度を向上させることのできる画像読取ユニットを提供する。画像読取ユニットにおいて、フレームは、上記照射面に対向するスペースを少なくとも2つに区画し、一方のスペースに上記光源ユニットを収納する第1の収納部と、隣接する他方のスペースに上記反射部材の少なくとも1つの反射部材を収納する第2の収納部を形成し、前記第1の収納部を挟んで前記照射面と反対側に、この照射面からの反射光を最初に受ける第1の反射部材を配置し、この第1の反射部材を上記他方のスペースに配置された反射部材との間に第1の反射部材からの上記読取光路を外れた光が他方のスペースにある反射部材に入射することを遮る遮光部材を設ける。
