An image sensor unit includes a light condenser that collects light from a reading target object; an image sensor that receives light and converts the light into an electric signal; an elongated housing that houses the light condenser and the image sensor; and an elongated rigid member attached to a side surface extending in the elongated direction of the housing. The side surface of the housing is provided with an attachment protrusion. The rigid member is provided with an attachment hole that penetrates from a surface facing the side surface of the housing to a non-facing surface on the opposite side, and the non-facing surface of the rigid member is provided with a concave. The attachment protrusion is inserted into the attachment hole, and a part of the attachment protrusion is fit into the concave.

An image reading apparatus includes a housing, a transport unit, a first reader, a controller, and a positioning mechanism. The controller controls the transport unit to transport a second medium different in thickness from a first medium in a first transport direction and then in a second transport direction opposite to the first transport direction. The positioning mechanism moves the first reader from a first position to a second position by using a drive force by which the transport unit transports the second medium in the first transport direction. The positioning mechanism maintains the first reader at the second position while the second medium transported by the transport unit in the second transport direction is passing the first reader, and moves the first reader from the second position to the first position after the first reader reads the image on the first side of the second medium.

An image reading apparatus includes a first sensor, a second sensor, a third sensor, a first processor that generates a first merge image based on first image data acquired by reading by the first sensor and second image data acquired by reading by the second sensor, and a second processor that generates a second merge image based on the second image data and third image data acquired by reading by the third sensor, and generates an output image by performing a linking process on the first merge image and the second merge image.

An imaging apparatus for use with a subject may include a light source structured to irradiate the subject with a yellow light, a magenta light and a cyan light at a delayed illumination timing; and a plurality of photodetectors structured to detect the intensity of the light coming from the subject when the yellow light is irradiated, the intensity of the light coming from the subject when the magenta light is irradiated, and the intensity of the light coming from the subject when the cyan light is irradiated.

Example implementations relate to an edge sensing apparatus. For example, an edge sensing apparatus consistent to the present disclosure may include a reflector in a beam path of a retroreflective sensor. The edge sensing apparatus consistent with the present disclosure may include a cover glass located between the retroreflective sensor and the reflector. The edge sensing apparatus consistent with the present disclosure may include a media feeder to feed a media along a media path between the cover glass and the retroreflective sensor.

A controller executes area defining processing for defining a middle area and two side areas, and ending processing. In a case where the document leading edge extends parallel to a main scanning direction, the controller executes the ending processing for non-skewed document. In a case where the document leading edge does not extend parallel to the main scanning direction, the controller executes the ending processing for skewed document. In which, the controller determines, in the middle area and the side areas, first, second, and third change positions, respectively, at each of which a type of a target read image data line changes from document data to document cover data, determines, based on the first change position and the second change position, whether a document has a rectangular shape, and ends the reading operation based on the third change position and the determination result as to the document shape.

Provided is a reading apparatus capable of preventing luminance unevenness in a reading range by correcting shading data. An original reading unit of a reading apparatus configured to read an image on an original includes a row of light receiving elements aligned in a main scanning direction orthogonal to a direction in which the original is conveyed. The reading apparatus generates shading data used in shading correction, based on the result of reading a white reference board via the original reading unit.

An image reading apparatus includes a conveyance unit, a casing, a reading unit, a support shaft, a first cable, and a second cable. The reading unit includes a reading sensor configured to read an image of the sheet conveyed in the conveyance path through the transparent member. The support shaft supports the reading unit in a manner of moving in a moving direction orthogonal to a longitudinal direction of the reading unit. The first cable is connected to a first connecting portion disposed in the reading unit, the first cable being held by the reading unit on one side in the longitudinal direction with respect to the support shaft. The second cable is connected to a second connecting portion disposed in the reading unit, the second cable being held by the reading unit on the other side in the longitudinal direction with respect to the support shaft.

A reading apparatus comprising a lower case, a reading portion, a drive portion and a stay is used. The reading portion moves between an open position in which the lower case is open and a closed position in which the lower case is closed and accommodates a reading sensor. The drive portion moves the reading sensor in a moving direction. The stay is coupled to the reading portion rotatably in one end and coupled to the lower case rotatably in the other end and moves a rotation shaft with in a direction orthogonal to the shaft. The drive portion is located outside a movable range of the reading sensor. When the reading portion is in the closed position, the stay is disposed in an area in which the stay overlaps the drive portion in the moving direction and overlaps the drive portion in height direction.

An image reading device includes a housing, a carriage, and a lock mechanism. The housing includes an exterior member and a document sheet placement surface. The carriage is configured to move in the housing along a predetermined specific direction. The lock mechanism is configured to lock the carriage to a lock position. The lock mechanism includes a supported portion and a locking portion. The supported portion is supported by the housing and provided between the exterior member and the carriage disposed at the lock position. The locking portion moves between a first position and a second position in response to a magnetic force of a magnet disposed at a specific position on the exterior member so as to, at the first position, engage the supported portion with the carriage disposed at the lock position, and at the second position, release engagement between the supported portion and the carriage.
