An image forming apparatus includes a main body, a feeder, and a relay device. The main body forms an image on a sheet. The feeder feeds the sheet toward the main body. The relay device connects the main body to the feeder. The main body is placed on a placement surface. The feeder is arranged opposite to the main body with the relay device therebetween in a direction along the placement surface. The relay device includes a conveyance unit and a casing which houses the conveyance unit. The conveyance unit conveys the sheet fed from the feeder to the main body and rotates relative to the casing with an axis as a pivot thereof. The axis extends in a cross direction intersecting with the placement surface.

A printing apparatus includes: an image former that forms an image on a pre-cutting sheet; a cutter that cuts the pre-cutting sheet on which the image is formed; and a hardware processor that controls the image former, wherein the hardware processor acquires image deviation information related to a deviation of an image with respect to a post-cutting sheet, and corrects at least one of a position, a tilt, or a shape of an image formed on the pre-cutting sheet so as to eliminate the deviation of the image based on the image deviation information.

The invention relates to a sheet alignment device (5) for a machine for the processing of sheets (B) consisting of a thin, flat material such as paper, cardboard or film, with a feed section, at least one sensor (30, 32) for determining the position and/or alignment of the sheet (B) and also at least two alignment modules (10), each having an alignment roller (12), to which a drive device (14) is assigned in each case, whereby there is assigned to each alignment module (10) a swivel device (16), with which the alignment roller (10) can be swivelled around a swivel axis (A) perpendicular to the feed section. The invention relates also to a machine for the processing of sheets (B) consisting of a thin, flat material such as paper, cardboard or film, whereby a sheet alignment device (5) of the aforementioned type is provided. The invention relates finally to a method for the aligning of a sheet (B) consisting of thin, flat material such as paper, cardboard or film by means of the following steps: the alignment of the sheet (B) is determined, the sheet (B) is speeded up, turned and/or displaced laterally by means of at least two alignment rollers (12), controllable with regard to circumferential speed and alignment, on a feed section.

A sheet folding apparatus includes a sheet folding unit disposed to fold a sheet and a conveyance unit disposed to feed the sheet to the sheet folding unit in a feed direction orthogonal to a fold direction of the sheet folding unit while correcting a skew of the sheet. The conveyance unit includes an elongated reference guide, a conveyance mechanism disposed to convey the sheet in the feed direction while exerting a force on the sheet toward the reference guide, an adjustment mechanism disposed to adjust an inclination of the reference guide with respect to the feed direction. The apparatus further includes an input unit through which a user inputs a folding misalignment amount of the sheet folded by the sheet folding unit. The inclination of the reference guide is corrected by the adjustment mechanism based on at least the folding misalignment amount inputted through the input unit.

A sheet processing apparatus includes a conveyance unit that conveys a sheet, a processing unit that performs processing on the sheet conveyed by the conveyance unit, and a controller that controls the conveyance unit and the processing unit. The processing unit includes a cutting unit capable of cutting the sheet along a cutting line, a holding unit that is configured to be movable between a holding position and a release position and that is disposed such that a holding line, which is formed on the sheet when the sheet is held, is substantially parallel to the cutting line, and an angle adjuster capable of adjusting an angle of the cutting unit and the holding unit with respect to a conveying direction.
