Abstract: A light guide member includes a main body part, and an entrance surface, a strip-shaped exit surface and a strip-shaped reflecting surface that are formed on the main body part. The illumination light is output from the exit surface. The reflecting surface extends in the first direction on a face placed opposite to the exit surface of the main body part and reflects the illumination light. The reflecting surface includes, on a flat face, a reflection pattern surface provided with a plurality of minute reflective concave parts having a function of reflecting the illumination light toward the exit surface. The reflective concave parts each include a deflection surface which deflects the illumination light in a direction in which a reflection angle widens in a cross sectional view in a second direction that is orthogonal to the first direction in a horizontal direction, and then reflects the illumination light.

Abstract: A reading module of the present disclosure is provided with a light source, an optical system, and a sensor. The optical system images, as reading light, reflected light of light radiated from the light source to an illumination object. The sensor converts the reading light imaged by the optical system into an electric signal. The optical system is provided with a mirror array in which a plurality of reflection mirrors are disposed in an array in a prescribed direction and a plurality of aperture stop portions that adjust an amount of the reading light. Each of the reflection mirrors is disposed at a prescribed distance from an adjacent one of the reflection mirrors in a prescribed direction.

Abstract: Provided is a reading module including a light source, an optical system, and a sensor. The optical system images reflected light of light emitted from the light source to the document, as image light. The sensor converts the imaged image light into an electric signal. The optical system includes a mirror array in which a plurality of reflection mirrors are connected, and a plurality of aperture stops. Neighboring reflection mirrors reflect light at different angles viewed from the main scanning direction.

Abstract: A reading module has a light source, an optical system imaging, as image light, reflected light of light radiated from the light source to a document, a sensor where a plurality of imaging regions for converting the image light imaged by the optical system into an electrical signal are arranged next to each other in the main scanning direction, and a housing the light source, the optical system, and the sensor. The optical system has a mirror array where a plurality of reflection mirrors whose reflection surfaces are aspherical concave surfaces are coupled together in an array in the main scanning direction, and an aperture stop portion adjusting the amount of the image light reflected from the reflection mirror. The amount of the image light striking the reflection mirror is increasingly small from opposite end parts of the reflection mirror toward its central part in the main scanning direction.

Abstract: An image reading apparatus includes a light irradiator, an optical system and a photoelectric converter. The optical system includes a reflection mirror unit and an aperture unit. The reflection mirror unit includes first and second reflection areas successively provided in a main scanning direction. The aperture unit includes a light shielding portion and first and second light passing holes for allowing the passage of the light reflected by each of the first and second reflection areas. The photoelectric converter includes a light receiving surface having first and second light receiving areas configured to receive the light passed through each of the first and second light passing holes and successively arranged in the main scanning direction. A length of the light receiving surface along the main scanning direction is set to be equal to or longer than that of the image reading area along the main scanning direction.
