Abstract This illumination device and this image reading device are each characterized by being provided with: a rod-like light guide body (2) that extends in the longitudinal direction, that guides light having entered from the outside, and that emits the light as linear light from the lateral surface (2b); a light guide body holder (3) that has holes (4a) through each of which an end surface (2a) of the light guide body (2) is inserted; a support (6) that supports the light guide body holder (3) so as to be slidable along the longitudinal direction; and a casing (7) which supports or stores the light guide body (2), a light guide body holder (4), and the support (6), and to which at least the support (6) is fixed, wherein the sliding direction of the light guide body holder (3) is restricted to the longitudinal direction by a support-side recess/projection part (8) that is one of a support side groove (8a) and a support side projection (8b) at least one of which is formed in the support (6) along the longitudinal direction. L'invention concerne un dispositif d'éclairage et un dispositif de lecture d'image qui sont chacun caractérisés en ce qu'ils comprennent : un corps de guidage de lumière (2) en forme de tige qui s'étend dans la direction longitudinale, qui guide la lumière ayant pénétré depuis l'extérieur, et qui émet la lumière sous la forme de lumière linéaire à partir de la surface latérale (2b) ; un porte-corps de guidage de lumière (3) qui comporte des trous (4a) à travers lesquels est insérée une surface d'extrémité (2a) du corps de guidage de lumière (2) ; un support (6) qui supporte le porte-corps de guide de lumière (3) de façon à pouvoir coulisser le long de la direction longitudinale ; et un boîtier (7) qui supporte ou stocke le corps de guidage de lumière (2), un porte-corps de guidage de lumière (4) et le support (6), et auquel est fixé au moins le support (6). La direction de coulissement du porte-corps de guidage de lumière (3) est limitée à la direction longitudinale par une partie en retrait/saillie côté support (8), laquelle est soit une rainure latérale de support (8a), soit une saillie latérale de support (8b), au moins une étant formée dans le support (6) le long de la direction longitudinale. 照明装置及び画像読取装置は、長手方向に延在し、外部から入射した光を導光して側面(2b)から線状の光として出射する棒状の導光体(2)と、導光体(2)の端面(2a)が挿入された孔部(4a)を有する導光体ホルダ部(3)と、導光体ホルダ部(3)を長手方向に沿って摺動可能に支持する支持部(6)と、導光体(2)、導光体ホルダ部(4)及び支持部(6)を支持又は収納し、少なくとも支持部(6)が固定された筐体(7)とを備え、導光体ホルダ部(3)は、長手方向に沿って少なくとも一方が支持部(6)に形成された支持部側溝部(8a)又は支持部側突起部(8b)である支持部側凹凸部(8)によって、摺動する方向が長手方向に規制されることを特徴とする。
