A sheet processing apparatus is configured to press a fold line that is formed on a sheet. The sheet processing apparatus includes: a sheet supporting unit configured to support the sheet in a pressing direction for pressing the fold line; a pressing unit configured to press the fold line that is formed on the sheet that is supported by the sheet supporting unit; and a pressing-force generating unit configured to generate a pressing force for pressing the sheet supporting unit against the pressing unit at a central part in a direction along which the fold line is formed.

Examples of imaging devices are described, in an example, an imaging device may include a first media roller assembly and a media duplexing apparatus. The media duplexing apparatus may include a second media roller assembly and a media diverter. The media diverter may be movable to a first position or to a second position to route a medium in the imaging device.

An image recording apparatus for recording an image on a sheet includes a recording section which records the image on the sheet in a transport passage for transporting the sheet in a transport direction and multiple plates which are spaced apart from each other in a widthwise direction. These multiple plates include a first type of plate and a second type of plate. Plates of a first type of plate are configured to overlap a sheet when viewed in a direction perpendicular to the transport direction and the widthwise direction, while plates of the second type of plate do not.

A printer includes a holder configured to house rolled recording paper, a cover that is attached to the holder to be openable and closable relative to the holder, and a contact part that is attached to the cover and configured to contact the recording paper. The contact part is configured such that the contact part substantially point-contacts the recording paper, and positions on the contact part contacting the recording paper change as the recording paper is unrolled.

An image reading apparatus according to an embodiment includes a first sensor, a roller, a correction unit, a second sensor, a control unit, and a scanner. Upstream to downstream positions with regard to a transportation direction of the sheet are determined in the following order: the first position, a second position, a third position. The first sensor detects the presence or absence of a fold of the sheet in the first position. If it is detected in the first position that the fold is present, the roller transports a sheet in a reverse transportation direction. The correction unit corrects the fold in the first position. The second sensor detects the presence or absence of the fold in the second position. If it is detected in the second position that the fold is present, the control unit controls drive of the roller in such a manner that the sheet is transported up to the first position in the reverse transportation direction. The scanner reads an image on the sheet of which the fold is corrected in the first position.

A sheet processing device for pressing a fold line formed in a sheet, the sheet processing device comprises a pressing portion configured to press a sheet while rotating about a rotation axis. The pressing portion includes a pressing unit having a projecting shape, disposed over a predetermined range in a direction of the rotation axis to have a position in a rotation direction about the rotation axis changed according to the direction of the rotation axis, and an impact absorbing member provided at a part of the pressing unit of the pressing portion, abutting on the sheet at first in the rotation direction of the pressing portion, the impact absorbing member configured to reduce impact upon abutting on the sheet.
