An image forming apparatus includes a scanner and a printing apparatus, wherein the scanner includes a scanning window; a transport unit configured to transport a document to a top surface of the scanning window; a scan unit configured to obliquely irradiate light to a bottom surface of the scanning window to scan the document; a transport guide member configured to be disposed to face the top surface of the scanning window to guide a transport of the document; and a curved reflection member configured to be coupled to the transport guide member to collect the light irradiated from the scan unit and to reflect the collected light toward the scanning window.

An image reading apparatus includes: a contact glass provided at an upper surface of a main body of the apparatus to set a manuscript thereon, an image sensor being positioned below the contact glass and having a reading surface on contact glass side for reading an image from the manuscript on the contact glass, a carriage supporting the image sensor accommodated in a sensor container formed to have a recess open to the contact glass side, a rail member slidably supporting the carriage, and a biasing member biasing the image sensor to the contact glass side via a biased portion adjacent to the reading surface of the image sensor. An upper end of the biasing member is positioned below the contact glass and above the lower surface of the image sensor.

An image reading apparatus including a reading unit comprising a photodetector configured to read an image information on a sheet, and a projecting portion, a case storing the photodetector therein, the case comprising a transparent portion configured to transmit light to be received by the photodetector, and a portion defining an opening through which the projecting portion is projected outward from the case, and an elastic portion provided to fill a space where the projecting portion is not present in the opening. The case movably stores the photodetector within a range where the projecting portion is movable in the opening.

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.

An image scanner includes an image sensor with a plurality of scanning elements arrayed in a main scanning direction, a carriage carrying thereon the image sensor, a pair of pulleys, a belt looped around the pulleys, a connector, and a restricting member. The connector protrudes from the carriage and is connected to the belt which is inserted in an entry port of the connector. When the belt is driven to rotate, the connector moves with the belt and moves the carriage in a sub-scanning direction. The restricting member contacts the belt when, in a state where the carriage is at a standby position, the belt shifts in a disengaging direction in which the belt tends to disengage from the connector through the entry port.

An image reading apparatus is provided. The image reading apparatus includes: a platen glass; a moving member; a reading section held by the moving member, the reading section having a reading surface, a light-receiving element, a substrate section, and a case section; a transmission member; and a first biasing section. The moving member includes a facing surface that faces the substrate section. The case section includes a first wall and a second wall. The transmission member includes a first contacting section, a second contacting section, and a connecting section. The first biasing section is disposed such that its one end makes a contact with the facing surface of the moving member and its other end makes a contact with the connecting section of the transmission member.

A mechanism for supporting a traveling body includes a traveling body which reciprocates and shifts, a track member extending in a direction in which the traveling body shifts, a track surface provided in the track member to slide the traveling body, a drive section that drives the traveling body, and a slide member provided in the traveling body to support the traveling body slidably via a lubricant between the track surface and the slide member. The slide member includes a slide contact portion that slides on the track surface, a slide barrier portion provided on at least one side of the slide contact portion along a slide direction of the slide contact portion, and a guide portion which scrapes the lubricant in association with sliding of the slide contact portion, and guides the lubricant to between the slide contact portion and the slide barrier portion.

An image reading apparatus, comprising an image reading unit configured to perform image reading, a drive unit configured to move a target in the image reading, and a signal generating unit configured to generate a signal for driving the image reading unit, the image reading apparatus configured to acquire, with moving the target by the drive unit, image data by the image reading unit performing the image reading based on a signal generated by the signal generating unit, wherein the drive unit moves the target such that the target changes at a speed according to a predetermined driving speed profile, and the signal generating unit generates a signal, based on the driving speed profile, at a timing making the moving distance of the target to be an equal interval.

An image reading apparatus includes: a contact glass provided at an upper surface of a main body of the apparatus to set a manuscript thereon, an image sensor being positioned below the contact glass and having a reading surface on contact glass side for reading an image from the manuscript on the contact glass, a carriage supporting the image sensor accommodated in a sensor container formed to have a recess open to the contact glass side, a rail member slidably supporting the carriage, and a biasing member biasing the image sensor to the contact glass side via a biased portion adjacent to the reading surface of the image sensor. An upper end of the biasing member is positioned below the contact glass and above the lower surface of the image sensor.

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.
