A multifunctional printer comprising a printer section, an auto-document feeder, a scanner section, and a finisher, wherein a finisher path leads from the auto-document feeder into the printer section and converges with a print path into a shared finisher path leading to the finisher, such that documents scanned with the auto-document feeder can be conveyed to the finisher such that it can perform a finishing operation on the documents.

A sheet post-processing device is mounted in an image forming apparatus that includes an image reading unit and an image forming unit. The image forming unit is located under the image reading unit with a space therebetween. The sheet post-processing device includes: a first tray that is located in the space and houses a sheet ejected from the image forming unit; a post-processing unit that is located in the space and performs post-processing on a sheet in the first tray; a transfer member that, after the post-processing is performed on a sheet in the first tray, transfers the sheet to a front side of the image forming apparatus; and a second tray that is located closer to the front side of the image forming apparatus than the first tray and houses a sheet transferred by the transfer member.

A scanner includes a scanning module. The scanning module has a scan channel and a scanning glass. A lower surface of the scanner is defined as a bottom wall of the scan channel. The scanning glass is positioned above the scan channel. A bottom surface of the scanning glass is defined as a top wall of the scan channel. The lower surface of the scanner has an upstream turn connected between an upstream section and a middle section of the lower surface of the scanner, the middle section of the lower surface of the scanner is parallel with the bottom surface of the scanning glass.

An image reading apparatus includes a stacking unit, a conveyance unit to convey stacked sheets, a reading unit, a white reference plate provided in a second position, and a processor. The reading unit is movable and, at a first position, reads a conveyed sheet image to obtain image data and, at the second position, reads the white reference plate. The processor generates, based on a plate reading result, a shading correction value and corrects the image data using the shading correction value. Based on whether the number of times in which reading the white reference plate has been performed is less than a predetermined number of times, the reading unit changes a time interval in a reading period that is from a first timing to a second timing. The processor generates, each time the white reference plate is read, the shading correction value based on the plate reading results.

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 information processing apparatus includes a processor configured to manage pieces of screen information in association with users, the screen information being related to an operation screen to be used for operating an image processing apparatus, identify a user who is going to use the image processing apparatus, and cause a display to display an operation screen created based on the screen information of the identified user, the display being used by the user when using the image processing apparatus.

An image reader device includes: an original placement part; a holder supporting the original placement part and forming, with the original placement part, a first boundary extending in a first direction; an image reading part movable in a vertical scan direction parallel to the first direction; and an open-close unit closable relative to the original placement part and including a press member which presses an original on the original placement part. The press member includes a first zone and a second zone arranged in the first direction. The first zone includes an extended portion extending beyond the first boundary from the original placement part to the holder when the open-close unit is located at a closed position.

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 power switching device for switching power between translational motion and rotational motion includes an active gear, a transmission mechanism, a translation mechanism, a functional gear, and a reset mechanism. The active gear can rotate in a first direction or a second direction opposite the first direction. The translation mechanism includes a runner and a pushing member. The active gear can switch between a first position and a second position. In the first position, the active gear meshes with the runner and rotates in the first direction or the second direction to drive the runner to rotate. In the second position, the active gear meshes with the transmission gear and rotates in the second direction to drive the functional gear to rotate.
