An image reading apparatus includes an image reading unit, a mounting portion, and a cover member. The cover member includes a first restricting portion, a lock portion, and an operation portion. The operation portion operated from outside the main unit is displaceable in a direction in which the lock portion deforms from the locking shape into the releasing shape. The mounting portion includes a second restricting portion and a part. The second restricting portion restricts displacement of the operation portion in the cover member mounted on the mounting portion in the second orientation. The part has a second aperture opening into the lock portion in the cover member mounted on the mounting portion in the second orientation from outside the main unit. The second aperture is an opening for the insertion of a tool for deforming the lock portion from the locking shape into the releasing shape.

An image reading apparatus includes a scanner unit configured to read a document, a document feed unit provided above the scanner unit and configured to feed the document and read the fed document, a first substrate configured to control an operation of the scanner unit, and a second substrate configured to control an operation of the document feed unit, wherein the first substrate and the second substrate are provided in a substrate placement section of the document feed unit.

When a feeding apparatus of a first type is connected to a first mounting surface, a processor outputs, to the feeding apparatus of the first type via a first signal terminal, a control signal. When the feeding apparatus of the first type is connected to a second mounting surface, the control unit outputs, to a feeding apparatus of a second type via a second signal terminal, a control command for controlling the feeding apparatus of the first type. When the feeding apparatus of the first type is connected to the second mounting surface, the feeding apparatus of the second type outputs, to the feeding apparatus of the first type via another signal terminal, a control signal based on a control command for controlling the feeding apparatus of the first type outputted from an image forming apparatus.

A reading apparatus includes a transport unit, a multi-feed detection unit, a reading unit, and a controller. When a multi-feed of the document is detected by the multi-feed detection unit, the controller multi-feeds causes the transport unit to discharge, downstream of the transport path, a multi-fed document for which the multi-feed is detected and then temporarily stops the transport, stores multi-fed page information indicating a page number of the multi-fed document, restarts the transport after the temporary stop, and after the reading unit reads a remaining document whose page succeeds a page of the multi-fed document, performs a re-reading process including the transporting and the reading of the multi-fed document, respectively, and inserts, based on the multi-fed page information, second read data acquired by the reading in the re-reading process into first read data acquired by the reading completed before the re-reading process.

An estimated image data calculator is configured to calculate, as estimated image data, for each of image data of respective colors outputted from an imaging element, on the basis of a pixel value of a first pixel on one of two lines adjacent to each other in the image data, and a pixel value of a second pixel on the other of the two lines and adjacent to the first pixel, image data of a non-reading region between a reading region in a document corresponding to the one of the two lines and a reading region in the document corresponding to the other of the two lines. A pixel value correcting unit is configured to correct at least one of the pixel value of the first pixel and the pixel value of the second pixel on the basis of the estimated image data.

This disclosure is related to a duplex scanning device. The automatic document feeder includes a paper feeder body, a paper inlet and a paper outlet. The paper cassette includes an upper paper tray and a lower paper tray adjacent to the paper inlet and the paper outlet. The cassette power module includes a motor set and a transmission part. The transmission part drives the paper cassette to move on one side of the automatic document feeder to control the lower paper tray to connect with the paper inlet or the paper outlet. Therefore, the double-sided scanning of the document is completed by two-pass duplex scanning.

A power switching device includes a translation mechanism, an active mechanism, and a transmission mechanism. The translation mechanism includes a rack. The active mechanism includes an active gear and a driver. The active gear connects with a first functional mechanism, and the driver drives the active gear to rotate in a first direction or a second direction. The transmission mechanism connects with a second functional mechanism. The active gear is switched between a first position and a second position. In the first position, the active gear is connected to the transmission mechanism and rotates in the first direction to drive the transmission mechanism to rotate, thereby driving the second functional mechanism to operate. In the second position, the active gear meshes with the rack and rotates in the first direction or the second direction to reciprocate on the rack so as to drive the first functional mechanism to operate.

An image reader includes a curvature forming unit that contacts a medium upstream of a nip position between a feeding roller and a separating roller, and forms a curvature of the medium in a width direction that intersects a feeding direction. The curvature forming unit is capable of switching between a first state in which a curvature is formed in a medium and a second state positioned in a direction that is retracted from a feeding path of the medium compared to the first state. The curvature forming unit is associated with posture switching of the device body, and is brought to the second state when the device body takes a first device posture, and is brought to the first state when the device body takes the second device posture.

A kiosk system is described that may have multilevel displays and multiple network antennas. Upper level displays may be non-touch and a lower level display may include a touch display. The upper level displays may be affixed to a body of the kiosk using brackets. The kiosk may include first and second network interfaces. The first network interface may be provided to enable user terminals local to the kiosk to wirelessly access network resources via the kiosk system. The second network interface may enable the kiosk to access a remote system. The kiosk may be equipped with a camera, microphone, and/or a speaker.

A control method for an apparatus for controlling a reading apparatus that performs reading in a transmission mode includes a read controlling step, a generating step and a processing step. In a read controlling step, the reading apparatus is controlled to read at least one film in the transmission mode based on a reading instruction from operating system standard software. In a generating step, a display image is generated, in which at least one frame image is arranged, based on a read image obtained by the reading in the read controlling step. In a processing step, a processing for displaying the display image generated in the generating step by using the operating system standard software, is executed.
