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.

A storing and issuing module (10) including a storage roller (50), a motor (60) associated with the storage roller (50), at least one transport tape (52) configured to wrap onto the storage roller (50) together with flexible documents, such as banknotes, conveyed in a conveying section provided with holding means (53, 54) actuatable for engaging flexible documents to be stored or issued with the transport tape (52), wherein the storing and issuing module (50) is capable of handling large storage capacity thanks to a mechanical layout that minimizes variations in the conveying section despite the great variations of the outer diameter of the storage roller due to the large capacity thereof.

In an image forming apparatus, a sheet is guided into a first conveyor path or a second conveyor path selectively when a first cover is in a closed position, and is ejected onto the first cover when the first cover is in an open position. Upon power-up, a controller causes a first conveyor roller to rotate but if the first cover is in the open position, when a sheet sensor detects a sheet, the controller does not cause a second conveyor roller to rotate, and causes a flapper to swing from a first position to a second position, and when a front end of the sheet reaches a position downstream of an upstream end of the flapper in a conveyance direction of the sheet conveyed by the first conveyor roller, the controller causes the flapper to swing from the second position to the first position.

A sheet conveyer having a conveyer path to convey a sheet therein, a first path and a second path branched from the conveyer path, a flapper, a pair of pivot-shaft portions, and a supporting section, is provided. The flapper is movable between a first position to guide the sheet from the conveyer path to the first path and a second position to guide the sheet from the conveyer path to the second position. The pivot-shaft portions are located apart from each other in a widthwise direction. The pivot-shaft portions support the flapper pivotably. The supporting section is located between the pair of pivot-shaft portions in the widthwise direction. The supporting section supports the flapper pivotably. The supporting section includes a rotation-shaft portion being rotatable, a bearing portion, in which the rotation-shaft portion is fitted, and a buffer member located between the rotation-shaft portion and the bearing portion.

A medium processing device includes a conveyance guide that forms first, second and third conveyance paths that intersect, a blade configured to be rotatable around a blade center point, and that switches a conveyance route of the medium by connecting any two of the three conveyance paths with each other, and a first pair, second pair and third pair of conveyance rollers that are rotatable and are configured to hand off the medium between two conveyance paths connected by the blade. The first pair of conveyance rollers includes a first roller and a second roller. The second roller is closer than the first roller to the third pair of conveyance rollers. A radius of the second roller is larger than a radius of the first roller. A first center holding distance is different from one or both of a second center holding distance and a third center holding distance.
