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: A reading module has a light source, an optical system, and a sensor. The optical system images, as image light, reflected light of light radiated from the light source to a document. In the sensor, the image light imaged by the optical system is converted into an electrical signal. The optical system has a mirror array and an aperture stop portion. In the mirror array, reflection mirrors are coupled together in an array in the main scanning direction. The aperture stop portion has a first aperture adjusting the amount of the image light reflected from a reflection mirror and a second aperture shielding stray light entering the first aperture from an adjacent reflection mirror. Between the first and second apertures, a reflection reduction mechanism is provided that reduces reflection, toward the first aperture, of light other than the image light traveling from the second to first aperture.

Abstract: According to the present disclosure, a reading module includes a light source, an optical system, and a sensor. The optical system images, as image light, reflection light of light with which the light source has irradiated a document. The sensor converts the thus imaged image light into an electric signal. The optical system includes a mirror array in which a plurality of reflection mirrors are connected together, and a plurality of aperture stop portions. The reflection mirrors each reflect light at an angle that is different, as seen in a main scanning direction, from an angle at which an adjacent one of the reflection mirrors reflects light. The plurality of aperture stop portions are disposed on one side of the mirror array with respect to an orthogonal direction which is orthogonal to the main scanning direction.

Abstract: An image reading device has a reading module including a light source, an optical system having a mirror array where reflection mirrors are coupled together in the main scanning direction and an aperture stop portion, a sensor where imaging regions for converting the image light imaged by the optical system into an electrical signal are arranged, and a housing, and has a reference drawing pattern determining connection positions between the imaging regions. The reference drawing pattern is composed of a plurality of pixel cut lines arranged to correspond to boundary lines between the reflection mirrors. The optical system is fixed on the housing at one point in the main scanning direction, and the pixel cut lines are arranged such that their distances from the boundary lines in the main scanning direction increase the farther away from the fixed position of the optical system in the main scanning direction.

Abstract: The optical scanning device includes a light source unit, a polygon mirror, a first scanning lens, a second scanning lens, and a container unit. The light source unit has a plurality of light-emitting modules for each emitting a laser beam. The container unit contains the levitating unit, the polygon mirror, the first scanning lens, and the second scanning lens. Each light-emitting module includes a light-emitting element for emitting a laser beam, a coupling lens, and a bracket. The coupling lens converts the laser beam emitted from the light-emitting element into a direction generally parallel to a main scanning direction, and moreover condenses the laser beam to a sub scanning direction. The light-emitting modules are placed in array in an up/down direction between neighboring ones of the protruding portions, and the bracket is fixed to the protruding portions on both sides via adhesive.
