摘要： A document scanning module includes an image sensor; and imaging lenses that focus light reflected from a document onto the image sensor to form an image. The imaging lenses include a front-group lens arranged on a document side, and a rear-group lens arranged on an image sensor side and having a width in a main-scanning direction. The rear-group lens includes an attachment portion extending toward the image sensor. The attachment portion is joined to a longitudinal side surface of the image sensor.

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.

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： 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： An edge detecting device includes processing circuitry. The processing circuitry is configured to acquire first color information and second color information in an image including a document region and a background region outside the document region. The first color information is color information of the background region and the second color information is color information of the document region. The processing circuitry is configured to detect a boundary between the background region and the document region from a change in color information between the first color information and the second color information.

摘要： An inclination detecting device includes processing circuitry. The processing circuitry is configured to detect, in image information that is an image of an object imaged by an imaging device at an imaging position where a background member forms a background, a first boundary between the background member and a shadow of the object; detect a second boundary between the object and the shadow of the object in the image information; and detect an inclination of the object in the image information from the first boundary and the second boundary detected by the processing circuitry.

摘要： An inclination detecting device includes processing circuitry. The processing circuitry is configured to detect, in image information that is an image of an object imaged by an imaging device at an imaging position where a background member forms a background, a first boundary between the background member and a shadow of the object at detection positions in at least one of main-scanning and sub-scanning directions on an outline of the object; detect a second boundary between the object and the shadow of the object at detection positions in at least one of the main-scanning and sub-scanning directions on the outline of the object in the image information; detect a boundary group including detection results of the second boundary at the detection positions; and detect an inclination of the object in the image information from detection results of the first boundary, the second boundary, and the boundary group.
