LIGHT GUIDE, ILLUMINATING DEVICE AND IMAGE READING APPARATUS |
摘要 |
A light guide having: a splitting section configured to split light emitted from a light source into at least two; and at least two light guiding sections arranged side by side in a predetermined width direction and configured to cause the light entering from the splitting section to propagate in a predetermined length direction. Each of the light guiding sections includes: a reflective section provided along the length direction and configured to reflect light incident thereon; an emission surface arranged opposite the reflective section and configured to emit the light reflected by the reflective section as a linear light beam having predetermined light distribution in the length direction; and at least a part of the emission surface is located farther in a direction opposite to the length direction than a forward end of the splitting section in the length direction. |

1. A light guide comprising:
a splitting section configured to split light emitted by a light source into at least two; and at least two light guiding sections arranged side by side in a predetermined width direction and configured to cause the light entering from the splitting section to propagate in a predetermined length direction, wherein: each of the light guiding sections includes: a reflective section provided along the length direction and configured to reflect light incident thereon; and an emission surface arranged opposite the reflective section and configured to emit the light reflected by the reflective section as a linear light beam having predetermined light distribution in the length direction; and at least a part of the emission surface is located farther in a direction opposite to the length direction than a forward end of the splitting section in the length direction. |
