摘要： An image reading device includes original illuminating means for applying illuminating light to a surface of an original which contains image information at an illuminating angle .alpha. with respect to a line normal to the surface of the original, and image reading means for reading light containing the image information and reflected by the surface of the original in response to application of the illuminating light thereto, at a reading angle .beta. with respect to said line normal to the surface of the original. The illuminating angle .alpha. and the reading angle .beta. are selected to meet the following relationship:-.alpha.-.phi..gtoreq..beta.>-90.degree.or-.alpha.+.phi..ltoreq..beta. 0) is an angle from the regular reflection of said illuminating light in order to remove the surface reflections from the surface of the original. Moreover, the illuminating angle .alpha. and the reading angle .beta. are selected to meet the following relationship:.vertline..beta..vertline.>.vertline..alpha..vertline. and .alpha..beta.>0.

摘要： An illumination device includes a light guide member having a bar-like shape and a light source disposed so as to face an end surface of the light guide member. The illumination device guides light from the light source in the light guide member and emits the light from a light emission surface of the light guide member formed in a longitudinal direction of the light guide member. The light emission surface includes a first light diffusing portion that is formed in a first portion near the light source and that has a protruding/recessed shape, and a second light diffusing portion that is formed in a second portion adjacent to an end of the first light diffusing portion, the end being away from the light source. The second light diffusing portion has a protruding/recessed shape and has lower light diffusivity than the first light diffusing portion.

摘要： A light guide includes an incident surface provided at least at an end portion of the light guide in a longitudinal direction, and receiving light from a light source, an output surface constituting a part of an outer peripheral surface, and outputting the light introduced through the incident surface, a reflecting surface extending along the optical axis so as to oppose the output surface, and including a plurality of reflection patterns that reflect the introduced light toward the output surface, and a reflecting plate opposed to a region in the outer peripheral surface other than the incident surface, the output surface, and the reflecting surface, and reflecting the light from the light source. The outer peripheral surface includes a sloped portion formed so as to come closer to the reflecting plate in a direction away from the incident surface in the longitudinal direction.
