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: 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: 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: An optical scanning device includes a light source, a deflector, and a first lens and a second lens. A light beam from the light source strikes a deflection surface on the deflector obliquely in the sub-scanning direction. For the first and second lenses, the shapes of their entrance and exit surfaces with respect to the light beam are defined by a main scanning direction shape formula and a sub-scanning direction shape formula that include different coefficients for one and the other sides with respect to the middle in the main scanning direction. The sub-scanning direction shape formula includes, as a variable, a sub-scanning direction curvature radius defined by a sub-scanning direction curvature radius definition formula. The sub-scanning direction curvature radius definition formula is given by a polynomial with a coordinate in the main scanning direction as a variable, and includes a first order term of the variable.

Abstract: The optical scanning device includes a light source unit. The light source unit has a plurality of light-emitting modules for each emitting a laser beam. The light-emitting modules are placed in array in an up/down direction between neighboring ones of protruding portions. An outermost diameter of a bracket in a region interposed between the protruding portions of the light-emitting modules placed on an upper side is larger than an outermost diameter of the bracket in a region interposed between the protruding portions of the light-emitting modules placed on a lower side. A width between the protruding portions in a region where the light-emitting modules placed on the upper side are interposed therebetween is larger than a width between the protruding portions in a region where the light-emitting modules placed on the lower side are interposed therebetween.
