Abstract: An image processing apparatus includes a scanning unit, a gloss detecting unit, and a glossy information processing unit. The scanning unit includes a light source and is configured to scan a document to be scanned at a first illumination position not resulting in halation caused by light of the light source output to the document, and scan the document at a second illumination position resulting in halation caused by the light output to the document. The gloss detecting unit is configured to detect a glossy portion of the document based on images scanned at the first illumination position and the second illumination position. The glossy information processing unit is configured to perform a predetermined process by using information represented by the detected glossy portion.

Abstract: An image reading apparatus includes a transfer device for transferring a sheet, and a reading device for reading an image of the sheet at a prescribed read position. A light volume detection device is arranged at a position of one side end in a direction perpendicular to a transfer direction of the sheet to be transferred to detect the light volume according to a deviation amount at a sheet transfer position in a direction perpendicular to the transfer direction of the sheet end. An operation device calculates the deviation amount with respect to a reference position of the sheet transfer position from a difference between the light volume detected by the light volume detection device when the sheet is not present at the sheet transfer position and the light volume detected by the light volume detection device when the sheet is transferred to the sheet transfer position.

Abstract: An image reading apparatus includes a platen which is set at an image reading position, a loading guide portion which is arranged upstream in a convey direction of an original to be adjacent to the platen and guides the original to an upper surface of the platen, a scoop-up guide portion which is arranged downstream in the convey direction of the original to be adjacent to the glass platen and guides a leading edge of the original, which has passed through the platen, by scooping up, a convey guide portion which is arranged to oppose the platen and scoop-up guide portion, to form a convey path between the convey guide portion and both of the platen and the scoop-up guide portion, a support portion which supports the convey guide portion to be slidable parallel to the platen, and a regulating portion which is arranged between the convey guide portion and the scoop-up guide portion to hold a constant gap between the convey guide portion and the scoop-up guide portion.

Abstract: A multi-sheet feed detection system comprises a photosensor configured to receive light emitted in a non-visible spectrum by a transmitter through at least one sheet, and a detection module configured to detect a multi-sheet feed condition based on an amount of non-visible light received by the photosensor.

Abstract: An image reading apparatus which enables a reduction of FCOT by omitting a home position search and a shading compensation after an input of a reading instruction for a succeeding original when reading different originals successively.

Abstract: An image reading apparatus has a reader to read document images and has a stationary image reading position. A transporter transports a document at constant speed onto the image reading position. The transporter includes a guide member and a transport member. The guide member guides document transport and is provided adjacent to the upstream side of the document reading position in the direction of document transport by the transporter. The transport member transports a document with gripping between the guide member and itself. The transport member is provided above the guide member.

Abstract: An original document feeding apparatus introduces an original document to a reading position to read image information of the original document, provided is a first delivery passage for delivering the original document from the reading position, a second deliverying passage branching off from the first delivery passage, and conveyance route switching unit selectively movable between a first position for introducing the original document to the first delivery passage and a second position for introducing the original document to the second delivery passage, each without projecting in the first delivery passage.

Abstract: An image scanner includes a single contact glass placed on a main body. The contact glass has a first range through which a first original document is passed to be scanned, and a second range over which a second original document is placed to be scanned. An image sensor scans the first original document at a fixed position in the first range, and the image sensor scans the second original document while the image sensor moves through the second range. An automatic document feeder is arranged on the first range of the contact glass to introduce the first original document through an introducing path to the fixed position and to eject the first original document through an ejecting path from the fixed position. The introducing path is formed from an introducing orifice to the fixed position, the introducing orifice being located at a side of the second range of the automatic document feeder. Further, an ejecting path is formed from the fixed position to an ejecting orifice.

Abstract: A copying machine and method for copying a designated area of an original document designates copying start and end positions. A controller controls partial copying in accordance with a first timing sequence corresponding to the copying start position and ends copying in accordance with a second timing sequence corresponding to the copying end position. If a repeat copying mode is prescribed, copying start and end positions which are designated in the first copying cycle are stored and used to make copies of a second and a set of following original documents. Thus, designation of copying start and end positions for subsequent copies is not necessary.

Abstract: A conveying unit conveys a recording sheet in a sheet conveying direction. A carriage includes a processing unit including an image carrier which is rotated about a rotational axis parallel to the sheet conveying direction. The processing unit forms a latent image on the image carrier by electrically charging and developing the latent image so as to produce a developed image. A transfer unit transfers the developed image on the image carrier to the recording sheet as a result of inserting the recording paper between the image carrier and said transfer unit as the carriage moves on the recording sheet in a carriage moving direction. A fixing unit fixes the developed image onto the recording sheet, and a supporting member rotatably supports the processing unit and the fixing unit. A moving unit moves the carriage in the carriage moving direction which is perpendicular to the sheet conveying direction.
