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.
Claims9
A reading module comprising:
- a light source arranged to illuminate a document;
- an optical system arranged to image reflected light of light emitted from the light source to the document, as image light;
- and
- a sensor including a plurality of imaging areas for converting the image light imaged by the optical system into an electric signal, wherein
- the optical system includes a mirror array including plurality of reflection mirrors connected in a main scanning direction in an array, each of the reflection mirrors having an aspheric concave reflecting surface, and a plurality of aperture stops each disposed between each reflection mirror and each imaging area of the sensor so as to adjust light intensity of the image light reflected by each reflection mirror,
- the reflection mirrors are arranged so that neighboring reflection mirrors reflect light at different angles viewed from the main scanning direction, and
- the imaging areas are arranged so that neighboring imaging areas do not overlap each other in a perpendicular direction that is perpendicular to the main scanning direction.
