An image forming apparatus in which at least part of an image scanner is disposed in an area below an original discharge unit and above an image forming unit.

Systems and methods are provided for document handling. Non-vision detection systems may be capable of detecting the dimensions, orientation, and/or position of a single sheet, or multiple stacked sheets. A document scanning arrangement may be capable of double sided scanning for sheets with various characteristics. The systems and methods provided may accommodate high throughput and rapid digitization of various types of documents, at a high quality.

An image forming apparatus includes: a light source that emits a laser beam; a polygon mirror that reflects the laser beam; a photoreceptor that is to be exposed to the laser beam reflected by the polygon mirror; a motor that rotates the polygon mirror; and a hardware processor capable of detecting sheet type, that is, type of a sheet conveyed in the image forming apparatus, wherein the hardware processor controls to rotate the motor at a first rotation speed until the sheet type is detected, and rotate the motor at a second rotation speed determined on the basis of the sheet type after detection of the sheet type.

A reading apparatus includes: a reading section configured to generate a first image being a read image of a first face of a document sheet and a second image being a read image of a second face of the document sheet; if there is a brightness change area including a bright part having a brightness change in a convex state and a dark part being in contact with the bright part and having a brightness change in a concave state at an identical position on both of the images, an identification section configured to identify the brightness change area as a wrinkle area; and an output section configured to output the first image having been subjected to image processing of the identified wrinkle area.

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 conveying unit to convey a document, first and second reading units, a reception unit, a selection unit, and a setting unit. The first reading unit generates image data form a document first side and the second reading unit generates image data from a second side in parallel with the first reading unit reading. The reception unit receives settings regarding a size, an orientation, and a document opening direction of the document. The selection unit selects either a first reading method causing the first and second reading units to read per the set size, and a second reading method causing the first reading unit to read the first side per the set size and causing the second reading unit to read an entire second side. The setting unit sets image data corresponding to the document second side reading by the second reading method.

An image scanning device includes a platen, an image scanning unit that scans at a single time documents placed on the platen and generates pieces of image data, and an image data processing unit that performs processing of the pieces of image data. When the image scanning unit generates pieces of first image data by scanning first surfaces of the documents, each of which is placed in one of predetermined areas on the platen, and generates pieces of second image data by scanning surfaces opposite to the first surfaces of the documents, each of which is turned over and placed again in the one of the predetermined areas, the image data processing unit associates one of the pieces of the first image data with a corresponding one of the pieces of the second image data for each of the predetermined areas, as image data of the front and back surfaces.

An image reading apparatus including a conveyance portion configured to convey a document in a conveyance path, and a reading portion configured to read an image of a document conveyed in the conveyance path. The reading portion includes an image sensor configured to read an image of a document, a casing accommodating the reading element and including an opening portion having an opening through which an optical path of the reading element extends toward the conveyance path, a transparent member fixed to the casing and covering the opening, and a shield member disposed between the transparent member and the casing, and electrically grounded.

Provided is a more desirable product. A scanner has a first sensor configured to read a document on a platen glass; a second sensor configured to read a first side of a moving document; and a third sensor configured to read a second side, which is the opposite side as the first side, of a moving document. The first sensor forms a reduced size image of the document; and the second sensor and third sensor image form a same-size image of light from the document.

An image forming apparatus 10a includes (i) an image input apparatus 1, (ii) a control section 5a, (iii) a document detecting section 24 including a blank page detecting section and a separator sheet detecting section, and (iv) a file creating section 31 for creating a file of image data. The image input apparatus 1 has a double-side reading function. The file creating section 31 has a blank page skipping function and a separating function. The control section 5a includes a function setting section 51 for enabling the double-side reading function and the blank page skipping function when enabling the separating function.
