    摘要： An improved illumination device shortens a redundant area of insufficient light intensity close to a longitudinal end thereof. The device includes a casing, a bar-shaped light guide housed in the casing to cause a light-emitting surface thereof to be exposed, a light-emitting unit secured to an end section of the casing, wherein light from the light-emitting unit is introduced into the bar-shaped light guide through the end face thereof and is totally reflected within the bar-shaped light guide to be emitted through the light-emitting surface, and a shielding section provided to cover an end section of the bar-shaped light guide including the redundant area at the end section of the casing close to the light-emitting unit. A notch is formed at the end section of the bar-shaped light guide on the light-emitting surface side close to the light-emitting unit, and light from the light-emitting unit is reflected on a rear surface of the shielding section through a gap between this notch and the light-emitting unit to be introduced into the bar-shaped light guide.

    摘要： 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 is equal to coincides with the width direction (sub-scanning direction) of the bottom face on which the patterns are formed.

    摘要： 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.

    摘要： A rod- or plate-shaped light guide includes a first end that receives illuminating light incident thereon, a bottom surface having a reflecting portion thereon for reflecting the light, an emitting face which emits the reflected light, and a protruding portion protruding longitudinally and continuously from the light guide at a second end thereof. The protruding portion has a reduced peripheral dimension compared to a peripheral dimension of an adjacent portion of the light guide, and a reflective body is provided on the protruding portion and covers a longitudinal end face of the protruding portion extending perpendicular to the emitting face. When viewed along an axial direction of the light guide, the reflective body does not jut out from an end face of the light guide even when the body wraps on to a side surface of the protruding portion or expansion occurs.

    摘要： 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.
