A post-processing device includes a stacking portion on which a medium having an image recorded thereon is stacked; an aligning portion that is disposed on the stacking portion and that aligns a position of an edge of the medium; a drawing member that draws the medium stacked on the stacking portion toward the aligning portion; and a guiding member that is disposed above the drawing member and that guides the medium that is transported toward the stacking portion, the guiding member including a vicinity portion that is in a vicinity of the drawing member and that is recessed so as to receive the drawing member.

A paper sheet transport apparatus (10) includes transport member that is slidable along the widthwise direction of a transport path (11) (e.g., a drive roller (36) and a driven roller (38)), and a paper sheet detection unit (inlet-side paper sheet detection sensor (70)) that is arranged on an upstream side of the transport member in the paper sheet transport direction along the transport path (11) and detects the position of the paper sheet in the widthwise direction of the transport path (11). A control unit (80) calculates an amount of movement of the transport member based on the position of the paper sheet in the widthwise direction of the transport path (11) detected by the paper sheet detection unit and a previously set predetermined position of the paper sheet in the widthwise direction of the transport path (11).

A paper medium recognition device according to one embodiment of the present invention includes: a main body that provides a transportation path in which an alignment reference line for aligning a paper medium is arranged on one side; and an alignment unit which has a transportation roller which transports the paper medium in the longitudinal direction along the transportation path, and which has an alignment roller that is arranged in the direction orthogonal to the transportation roller so as to transport the paper medium in the width direction toward the alignment reference line. A phase difference is provided during the rotation of the transportation roller and the alignment roller, and thus the paper medium can be alternately transported in the longitudinal direction and width direction.

An image forming apparatus includes: a pair of rollers for conveying paper; a rocking mechanism for rocking the pair of rollers in a second direction orthogonal to a first direction., the first direction being a paper conveying direction; an upstream pair of rollers provided upstream of the pair of rollers in the paper conveying direction for conveying the paper; an upstream rocking mechanism corresponding to the upstream pair of rollers for rocking the upstream pair of rollers in the second direction; a first paper detector for detecting an end position of the paper in the second direction; and a controller controlling the rocking mechanism based on the paper end position to effect first rocking correction in which the pair of rollers is rocked, wherein the controller controls the upstream rocking mechanism to effect second rocking correction in which only the upstream pair of rollers is rocked.

A sheet separation device includes a sheet separation unit, a displacement detector, a displacement adjuster, and a controller. The sheet separation unit performs a sheet separating operation and a sheet inserting operation. The displacement detector detects a displacement amount of the two-ply sheet when the two-ply sheet is displaced in a width direction of the two-ply sheet and detects a displacement amount of the inner sheet. The displacement adjuster adjusts the displacement of the two-ply sheet in the width direction before the sheet separating operation, based on the displacement amount of the two-ply sheet in the width direction detected by the displacement detector. The controller causes the displacement adjuster to adjust relative positions of the two-ply sheet and the inner sheet between the sheet separating operation and the sheet inserting operation, based on the displacement amount of the inner sheet in the width direction detected by the displacement detector.

An apparatus for automatically aligning bills includes: a plurality of skew control units including a driving roller unit, a body, a first gear unit, and a second gear unit; a first motor unit connected with the first gear unit through a first power transmission member and providing a driving force to the driving roller unit; a second motor unit connected with the second gear unit through a second power transmission member and providing torque to the body; and ball caster units having a spherical shape and coming in contact with a second side of the bill.

Examples include a processing machine for processing a substrate. At least one alignment segment is arranged before at least one processing unit of the processing machine. The at least one alignment segment includes a plurality of transport sections following one another in the transport direction. The at least one alignment segment includes a dedicated drive for axially adjusting at least one of the transport section. The at least one transport section includes at least one first transport sub-section and at least one second transport sub-section in the transverse direction. The first transport sub-section and the second transport sub-section are drivable relative to one another at differing speeds in the circumferential direction. The alignment segment includes a transport section that includes the dedicated drive for axially adjusting the transport section and the transport sub-sections that can be driven relative to one another at differing speeds.
