Abstract:
A light guide includes a first exit portion emitting first exiting light, a second exit portion emitting second exiting light in a different direction than the first exiting light, and a reflecting portion reflecting light entering the light guide to each of the first and second exit portions. The first and second exit portions respectively have first and second curved surfaces each having a convex cross section perpendicular to the long axis direction. The second exit portion is connected to the first exit portion in the direction perpendicular to the long axis direction. The reflecting portion is provided, in a plane facing the first exit portion and the second exit portion, at a position shifted in the direction perpendicular to the long axis direction from a position where a normal to the plane passes through a connection portion between the first and second exit portions.

Claim (Index 10):
An image reading device comprising two light guide assemblies, a first unit and a second unit, each including (i) a light guide extending in a long axis direction and having an end in the long axis direction from which light enters the light guide and (ii) a housing retaining the light guide, the first unit and the second unit being on opposing sides of an object to be irradiated with the light from the light guide,\n wherein the light guide comprises:\n a first exit portion having a first curved surface having a convex cross section perpendicular to the long axis direction, and emitting first exiting light; \n a second exit portion having a second curved surface having a convex cross section perpendicular to the long axis direction, being connected to the first exit portion in a direction perpendicular to the long axis direction, and emitting second exiting light in a direction different from a direction of the first exiting light; \n a first reflecting portion disposed in a plane portion facing the first exit portion; and \n a second reflecting portion disposed in a plane portion facing the second exit portion, \n the second exiting light irradiates an area different from an area of the object to be irradiated with the first exiting light, the housing retains imaging optical system to focus scattered light, the scattered light being the second exiting light, from the light guide, that is reflected on the object to be irradiated, and the first exiting light emitted from the first unit enters the imaging optical system of the second unit, and the first exiting light emitted from the second unit enters the imaging optical system of the first unit.
