    摘要: A light exit surface of an illuminating lens has a first light exit surface and a second light exit surface. The first light exit surface is recessed toward a point on the optical axis, and the second light exit surface extends outwardly from the periphery of the first light exit surface. The first light exit surface has a transmissive region and a total reflection region. When the position of a light source on the optical axis is defined as a starting point, the transmissive region transmits light that has been emitted from the starting point at a relatively small angle with respect to the optical axis, and the total reflection region totally reflects light that has been emitted from the starting point at a relatively large angle with respect to the optical axis. A reflective layer is formed on a bottom surface that surrounds a light entrance surface and faces oppositely to the light exit surface. The reflective layer reflects light that has been emitted from the light source, totally reflected repeatedly at the light exit surface, and then reached the bottom surface.

    摘要: An image reading device comprising a rotary polygon mirror (6) for scanning a light flux from a light source (1), an imaging optical system (4) for forming on a reflection plane of the mirror (6) a linear image larger than the width in a main scanning direction of the one reflection plane, and a curved-face mirror (7), wherein the light source (1), the imaging optical system (4), the rotary polygon mirror (6) and the curved-face mirror (7) are disposed in different positions in a sub-scanning direction, a light flux from the imaging optical system (4) shines obliquely onto the polygon mirror (6), and a light flux reflected off the mirror (6) beams obliquely onto the curved-face mirror (7). Since one curved-face mirror can beam a light flux reflected from the rotary polygon mirror onto a surface to be scanned and the rotary polygon mirror having a small inscribed radius and many reflection planes can be used, satisfactory optical performance and high-speed feature can be realized.

    摘要: The present invention relates to a surface light source, including a light source section made up of plural light emitting diodes and lenses that expand light from these light emitting diodes. The lens in the light source section has a light incident surface on which light from the light emitting diode is incident with an optical axis at a center, and a light exit surface that expands and emits the incident light. The light incident surface has a continued depressed surface, while the light exit surface has a continued projected surface. The lens performs such that “sag Y” decreases from a maximum value “sag Y0” with an increment of “θi”, where θi is an angle included between a straight line, connecting an arbitrary point on the light exit surface and a base point on the optical axis which corresponds to a position of the light emitting diode, and the optical axis; sag Y is a distance measured in a light axis direction from the base point on the optical axis to the arbitrary point on the light exit surface; and “sag Y0” is a value of sag Y when angle θi is 0 (zero) degree, and wherein the light exit surface except a vicinity of the optical axis takes a shape satisfying a relation of 10 degrees

    摘要: An illuminating lens has a light entrance surface and a light exit surface. The light exit surface has a first light exit surface recessed toward a point on an optical axis A and a second light exit surface extending outwardly from the periphery of the first light exit surface. The first light exit surface includes a transmissive region located in the center of the first light exit surface and a total reflection region located around the transmissive region. The transmissive region transmits light that has been emitted from a starting point Q, which is the position of a light source on the optical axis A, at a relatively small angle with respect to the optical axis A. The total reflection region totally reflects light that has been emitted from the starting point Q at a relatively large angle with respect to the optical axis A.
