A first image reading portion is disposed in a body portion. A conveying device is disposed in a cover portion. A second image reading portion is disposed in the cover portion. An inclination derivation portion derives two inclination angles of a document sheet respectively corresponding to the first image reading portion and the second image reading portion by performing image processing on two read images obtained by the first image reading portion and the second image reading portion. An information output portion outputs inclination correction information based on the difference between the two inclination angles through an information output device.

A sheet conveying device includes a sheet placement table, a sheet discharge table, a conveyance mechanism, raising/lowering mechanism, and a raising/lowering control portion. The sheet discharge table is located below the sheet placement table. The conveyance mechanism conveys a sheet placed on the sheet placement table onto the sheet discharge table via an execution position at which image processing is executed by an image processing portion. The raising/lowering mechanism raises and lowers the sheet placement table. The raising/lowering control portion controls the raising/lowering mechanism to lower the sheet placement table when a human detection sensor configured to detect a human in a detection region has detected a human in the detection region.

An image forming apparatus includes an image reading device, a holding member that is rod-like, and an image forming device having an image forming unit that forms an image on a sheet, and having a wall part having a hole. The image reading device reads an image on a document, is provided on the image forming device, and rotates around a rotation shaft openable and closable with respect to the image forming device. The holding member has one end attached on the image reading device, and holds the image reading device opened with respect to the image forming device when another end of the holding member is inserted into the hole formed in the wall part. The holding member includes a first regulation part that comes into contact with a lower surface of the wall part to regulate detachment of the other end of the holding member from the hole.

A control portion controls a reading portion and a discharge portion, and when a document is placed in a document placement portion, a transport path transports the document, and the reading portion reads an image of the document. When the discharge portion discharges the document for which reading is completed by the reading portion, a document receiving portion receives the document discharged by the discharge portion. The document receiving portion has a first region that overlaps the document placement portion when seen in a vertical direction, and a second region that does not overlap the document placement portion when seen in the vertical direction, and the discharge portion discharges the document so that at least part of the document is placed on the second region.

An image reading apparatus includes a transport unit which transports a document, and reading units which read an image of the document which is transported. It is assumed that an operation of reading an image when specific setting information is not input to a control device of the image reading apparatus is set to a first reading mode, and an operation of reading an image when specific setting information is input to the control device is set to a second reading mode. In this case, in the second reading mode, image data of an image with a resolution which is equal to that in the first reading mode is generated, while causing the reading units to read an image from a document which is transported by the transport device at a lower speed than that in the first reading mode.

An automatic desktop personalization device, for security booklet documents, includes a camera, an inkjet printing module, a laser marking module, a chip encoding module, and a transport mechanism. The inkjet printing module includes a printing head and is configured to print within a printing zone. The laser marking module is configured to mark within a marking zone. The transport mechanism is configured to automatically transport a security booklet document along a Y-axis linear direction, from an entrance to an exit, through printing positions and a marking position. The entrance and the exit are the same. The printing head is movable alongside an X-axis linear direction that is perpendicular to the Y-axis linear direction. The inkjet printing module includes the transport mechanism. The laser marking head is adjacent an inkjet printing bridge, such that the marking zone and the printing zone are at least partly combined.

A document feeder includes a document placing tray on which a document is placed; a document discharging tray on which a document discharged from a document discharging port in a discharging direction is stacked; and a light source that radiates light to the document discharging tray. The document discharging tray is disposed below the document placing tray. The document discharging tray has a protruding portion protruding upward from the surrounding area. The light source is disposed within a region having a width that is the same as a document having a maximum size in the width direction.

An ink ejection timing adjustment method on an inkjet recording apparatus includes an information acquiring step of acquiring at least recording medium information with a reading sensor, a printing step of printing a test pattern on a recording medium on a conveying belt, a calculating step of calculating a delay time by adding to a default set time a correction time corresponding to a correction value for ink ejection timing entered based on the printed position of the test pattern, and a setting step of setting the delay time as a predetermined time at the lapse of which after, as a result of the conveying belt turning, an opening passes a reading position a recording head starts to eject ink to the opening.

An image reading device includes a conveyance unit configured to convey a carrier sheet and a reading object, a reading unit configured to read an image of the reading object, a display unit configured to receive an input of information about whether the reading object is conveyed using the carrier sheet, and a control unit configured to determine whether the reading object is being conveyed using the carrier sheet. The control unit performs predetermined processing on the image read by the reading unit when it is determined that the reading object is being conveyed using the carrier sheet. The control unit does not perform the predetermined processing on the image read by the reading unit when it is determined that the reading object is being conveyed without using the carrier sheet.

In a medium conveying device, a projector projects light, a projection light amount of the light changes, at every fixed time, to a first projection light amount and a second projection light amount less than the first projection light amount, a receiver receives the light projected from the projector, a processor determines, at fixed sampling timings, whether a reception light amount of the receiver is at a first reception light level or a second reception light level smaller than the first reception light level, determines, when the reception light amount alternately changes to the first reception light level and the second reception light level, that a medium is not present on a conveying path, and determines, when the reception light amount is fixed to either the first reception light level or the second reception light level, that the medium is present on the conveying path.
