A conveyance device that conveys paper through a conveyance path along a surface thereof includes: a conveyance guide that has a guide surface to be a wall surface on one side of the conveyance path, an opening being formed in the guide surface; a paper detection unit at least including a detection member, which is arranged in a space that communicates with the conveyance path through the opening, and configured to detect, with the detection member, a leading end of the paper that reaches the opening; and a movable body that brings the detection member into a retracted state, in which a main part thereof is covered from the space, after the leading end of the paper is detected.

A conveyance apparatus includes a separation unit configured to separate and convey a sheet, a detection unit configured to detect a floating of the sheet passing through the separation unit, and a control unit configured to stop separate conveyance by the separation unit if the detection unit detects the sheet for not less than a predetermined time and/or a predetermined count.

Embodiments of systems and methods are disclosed herein to transfer a printed election sheet from a printer to a scanner, which is separate and distinct from the printer, without human intervention. More specifically, the present disclosure provides a retrofit automatic document feeder (ADF), which may be “retrofit” or adaptively coupled between a printer and a scanner for automatically transferring a printed election sheet output from the printer to the scanner, where it is scanned to generate a scanned image of the printed election sheet. Unlike conventional ADFs incorporated within printers, scanners and multi-function printers, the retrofit ADF disclosed herein is coupled to receive a printed election sheet output from an output port of the printer, advance the printed election sheet away from the output port of printer and automatically transfer the printed election sheet to an input port of the scanner.

A recording apparatus includes: a recording unit that performs recording on a medium; a medium discharging section that discharges the medium on which recording has been performed; a medium receiving section that receives the medium discharged by the medium discharging section; a face-down discharge path that guides, to the medium discharge section, the recorded medium with a recorded side thereof facing downward; a document movement path that is provided at an upper part of a housing constituting an outer casing of the recording apparatus and along which a document moves; and a reading unit provided in the document movement path to read the document. The medium receiving section also serves as a support tray that supports the document to be inserted into the document movement path or the document exiting from the document movement path.

An automatic document feeder, which is included in an image reading device and an image forming apparatus, includes first and second document trays, a document output tray, a document conveying passage, multiple document conveying bodies, a drive source, a detector, and a controller. The multiple document conveying bodies include a document holding and conveying body to convey and hold the original document sheet on the second document tray. On detection of the original document sheet on the second document tray while conveying a different original document sheet from the first document tray, the controller stops feeding the different original document sheet, causes the different original document sheet downstream from the document holding and conveying body in a document conveying direction to be conveyed to the document output tray, and stops the drive source after the different original document has been conveyed to the document output tray.

A multifunction apparatus includes a reading mechanism including a document discharge port configured to discharge a document, a recording mechanism including a medium discharge port configured to discharge a recording medium, and a control unit, and a path through which a leading end of the recording medium discharged from the medium discharge port passes and the document discharged from the document discharge port have such a positional relationship to intersect with each other at an intersecting position, and when the leading end of the recording medium is discharged from the medium discharge port in a stop state where the document discharged from the document discharge port blocks the path of the leading end of the recording medium discharged from the medium discharge port, the control unit performs a predetermined operation for canceling the stop state before causing the leading end of the recording medium to reach the intersecting position.

An image reading apparatus is configured to read an image of each of documents transported in a transport path from an upstream side to a downstream side in a transport direction, acquires a correction factor for correcting a read image on the basis of a fed document number, and corrects the length of the read image in the transport direction on the basis of the correction factor which has been acquired.

An image processing apparatus includes a platen, a fixed-document detection unit, a determination unit, and a processing-target selection unit. The determination unit determines whether the document on the platen is a left document or not when the document on the document tray and the document on the platen are detected, upon acceptance of the document-reading-starting instruction by the instruction accepting unit. The processing-target selection unit sets image data obtained by a conveyed-document reading unit as a processing target when the determination unit determines that the document on the platen is the left document, and inquires which image data obtained by the conveyed-document reading unit and a fixed-document reading unit, to be set as the processing target of the user when the determination unit determines that the document on the platen is not the left document.

A printing apparatus includes a feeding units, a detecting unit, a designating unit, and a control unit. The detecting unit detects a respective operation on each of the feeding units. The designating unit designates, in response to a user operation via a display, which of the feeding units is to be used for printing. The control unit executes, in response to a command to execute predetermined printing, a process based on a first feeding unit on which an operation has been last detected by the detecting unit and a second feeding unit designated by the designating unit. Based on that the first and second feeding units are different, the control unit displays, as the process, a predetermined screen on the display. Based on that the first and second feeding units are the same, the control unit executes, as the process, the predetermined printing on a second feeding unit fed sheet.

In a technique to implement document reading by making use of a mobile terminal and an image forming apparatus, control to cause an image of a document to be captured at accurate timing is important. The present invention is a mobile terminal capable of communicating with an image forming apparatus and the mobile terminal includes: an image capturing unit; an instruction unit configured to transmit discharge instructions to discharge a document to the image forming apparatus in which the document is set in a sheet feed unit; a state acquisition unit configured to acquire a state of the image forming apparatus by communicating with the image forming apparatus; and an image capturing instruction unit configured to detect timing at which the image forming apparatus discharges the document based on the state of the image forming apparatus acquired by the state acquisition unit and to give instructions to capture an image of the document to the image capturing unit at the timing.
