摘要： A lens unit includes a tube lens; a single lens arranged at a downstream side with respect to the tube lens in an optical incidence direction; and a supporting member that supports the tube lens and the single lens. Reflection light from a document is condensed on an image sensor by the tube lens and the single lens to form an image. An end surface part, not facing the tube lens, of the single lens is in direct contact with the supporting member.

摘要： An image reading apparatus includes a light source to emit at least light in a first wavelength range and light in a second wavelength range, a background member having different light reflectances in the first and second wavelength ranges, an imaging device, and circuitry. The imaging device receives reflected light from the background member irradiated with the light in the first wavelength range, and generates first read information. The imaging device further receives reflected light from the background member irradiated with the light in the second wavelength range, and generates second read information. The circuitry detects presence or absence of a first foreign substance based on a difference in reading level of the first read information generated by the imaging device; and detect presence or absence of a second foreign substance based on a difference in reading level of the second read information generated by the imaging device.

摘要： An image reading device includes a frame, an image reading unit, a guide, a biasing member, and an adjuster. The image reading unit reads, while moving in a predetermined direction, image information of a document placed on an exposure glass. The guide extends in the predetermined direction and is supported by the frame, to engage and guide the image reading unit to move the image reading unit in the predetermined direction. The biasing member biases the guide in a direction against a direction in which the guide bends due to weight of the guide and weight of the image reading unit. The adjuster adjusts a biasing force of the biasing member against the guide.

摘要： A lens unit includes a barrel lens; a single lens disposed downstream in a light incidence direction relative to the barrel lens, having a concave lens surface opposite the barrel lens, being an anisotropic lens in a main and sub-scanning directions, having a gradually increasing thickness from a center to lateral ends, and including fixed faces disposed on a side of the concave lens surface at both lateral ends in the longitudinal direction of a non-optical surface thereof; a single lens holder formed of lens holding parts to support the barrel lens, disposed between the barrel lens and the single lens, and including lens holding faces to be fixed to the fixed faces of the single lens; and an image sensor. The lens unit is configured such that reflected light from a document is focused on the image sensor via the barrel lens and the single lens.

摘要： A lighting device includes a light source, a board, and a light guide. The light source emits light. The board mounts the light source on a mount surface perpendicular to a light emission surface of the light source. The light guide has an incident surface which the light emitted from the light source enters. The incident surface is opposed to the light emission surface. The light guide extends from the incident surface in a direction of the emitted light and is bent toward an irradiated surface of an irradiation target on a way of the light guide. The board is disposed such that an opposite surface of the board opposite the mount surface is opposed to the irradiated surface of the irradiation target.

摘要： An image capturing device includes a frame; a light source provided in the frame to irradiate a target with light; an image sensor that receives light reflected by the target to capture an image of the target; an imaging lens unit formed of a plurality of lenses configured to focus the light reflected by the target on the image sensor; and reflecting mirrors to direct the light reflected by the target to the imaging lens unit. In the image capturing device, an image capturing position is corrected by changing a posture of the reflecting mirror relative to the frame of the image capturing device and a skewed image is corrected by changing the posture of the reflecting mirror relative to the frame of the image capturing device.
