Abstract: To provide a rod-like light guide and a line lighting device including the rod-like light guide, both of which are easy to include in an image reading device, a contact-type image sensor and an image reading device. For instance, a protruding portion having a flat or curved surface is formed by grinding an end face of a rod-like light guide in a longitudinal direction while leaving at least 80% of the surface area of the end face, and a reflective surface is formed by bonding a heat transfer film to the protruding portion. Thus, even if a portion of the protrusion portion melts when performing thermal processing on the heat transfer film, the portion will not jut out beyond a cross-sectional area of the rod-like light guide, and the rod-like light guide can be easily contained in a case.

Abstract: The present invention provides a light guide, a line-illuminating device, and an image-scanning device that provide excellent uniformity in the amount of light produced. A light-reflecting portion comprised of spherical concave surfaces becomes a reflecting surface having spherical convex surfaces when it is seen from the inside of the light guide. Even when the incident angle of light from the light source unit is slightly offset, the reflection angle in spherical convex surfaces significantly changes, and light is reflected uniformly toward the upper surface serving as a light-emitting surface. In particular, when the fine spherical concave portions of the light-reflecting portion have a small depth, the incident light from the end surface is reflected toward the upper surface, serving as a light-emitting surface, and both side surfaces without reflecting back to the light-emitting unit side, so that uniform reflection can be achieved.

Abstract: A light guide, a line-illuminating device, and an image-scanning device are provided which are excellent in uniformity of the light amount. A light-reflecting portion comprised of tubular concave surfaces becomes a reflecting surface having tubular convex surfaces when seen from the inside of the light guide. With such structure, even when the incident angle of light from a light source unit slightly displaces, the reflection angle in the tubular convex surfaces significantly changes. In an irregular surface having a triangular shape, as in a conventional example, the incident angle becomes almost uniform in the area far from the light source unit, and thereby the reflection angle also becomes uniform. Consequently, it is difficult to achieve uniform reflection in the main-scanning direction. However, with the tubular concave surfaces, light is reflected uniformly toward the upper surface as a light-emitting surface.

Abstract: A rod-shaped light guide which does not cause unevenness in color at the portion near an incident face is produced by injection-molding transparent resin such as acryl and its surfaces include a light-emitting surface, a bottom face, left and right sides and end faces. One end face opposes a light emitting unit, and light scattering patterns for scattering light incident from the end face are formed on the bottom face. The light scattering patterns are different in shape between a portion near the end face as the incident face and a portion away from the end face. The light scattering patterns formed at the portion near the incident face are composed of a large number of fine hemispherical concaves, whereas the light scattering patterns at the portion away from the incident face are composed of triangular grooves or half cylindrical grooves, and the axial direction of these triangular grooves or half cylindrical grooves coincides with the width direction (sub-scanning direction) of the bottom face on which the patterns are formed.

Abstract: A structure of a line lighting device permits a rod-like light guide to be attached to a case without rubbing against the case. An end portion of the rod-like light guide provided with a pin is inserted into an opening in a case main body and pushed down, thus making the pin engage with a recess in the case main body. At this time, a distal end of the rod-like light guide is inserted, to some extent, into an opening in a light emitting unit fixing portion. Subsequently, the rod-like light guide is pushed down and pivoted around the pin so as to be completely contained within the case main body. In this state, the distal end of the rod-like light guide is fitted into the opening and the end face of the rod-like light guide is flush with the outer side face of the light emitting unit fixing portion.

Abstract: A line-illuminating device which is resistant to shrinkage problems caused by repetition of heating and cooling includes a white casing made of polycarbonate or the like, a light guide made of an acrylic resin or the like and accommodated in the casing such that the light-emitting surface thereof is exposed, and light-emitting elements (for example, light-emitting diodes) as a light source provided on both ends of the casing so as to abut against the end surfaces of the light guide without a gap. The casing is divided into two portions in the longitudinal direction, and a gap is formed between the two divided portions. With this gap, even if the light guide shrinks due to repetition of heating and cooling, the divided portions can effectively shrink together with the light guide via the gap, and the abutting state between the end surface of the light guide and the light-emitting element can be maintained.
