This disclosure provides methods, components, devices, and systems for providing positioning and alignment of raw stock sheets during the manufacturing process. Some aspects, more specifically, relate to detecting a position of a raw stock sheet lifted from an initial position using proximity sensors and realigning the sheet to a desired position. Current techniques can cause misalignment or damage to sheets during placement. In some aspects, a raw stock sheet can be analyzed by a plurality of sensors to accurately and consistently place raw stock sheets from an initial position to a desire position for downstream manufacturing processes.

An electrode stacking apparatus provided with a planar motor device (B) comprised of a flat plate-shaped stator (50) and a plurality of movers (40) able to move on a flat surface (51) of the stator in any direction along the flat surface (51) and able to rotate about a perpendicular axis of the flat surface (51) in a state magnetically floating from the flat surface (51). When stacking a new sheet-shaped electrode (1) held by an electrode conveyor device (A) arranged above the planar motor device (B) on a stacked electrode holder (60) of a mover (40), the mover (40) is made to move in synchronization with movement of the new sheet-shaped electrode (1) so that the new sheet-shaped electrode (1) continues to face the sheet-shaped electrode stacking position on the stacked electrode holder (60).

A sheet conveyance device comprises: a skew detector that detects a skewed amount with respect to a conveyance direction of a sheet to be conveyed; and a skew corrector that corrects skew feeding of the sheet, and the skew corrector includes a guide member that supports the sheet along a width direction, and displaces the guide member so as to rotate a region in the width direction of the sheet supported by the guide member about an axis parallel to a conveyance direction according to a skewed amount of the sheet.

A medium transport device includes a positional corrector configured to transport a medium and correct a position of the medium in a width direction of the medium by moving the medium in the width direction, a first inclination corrector disposed on a transport path of the medium and configured to correct an inclination of the medium relative to a transport direction of the medium, and a second inclination corrector configured to correct the inclination of the medium on an upstream side of the first inclination corrector in the transport direction.

A recording apparatus having a support portion that supports a roll having a wound sheet, a drive portion, a conveying passage, a conveyer, and a recording portion. The drive portion rotates the supported roll in a first direction to feed the sheet from the roll, and rotates the roll in a second direction to rewind the sheet onto the roll. The conveying passage guides the sheet fed from the roll in a feeding direction and has first and second positions upstream of the conveyer in the feeding direction. The drive portion performs, before the sheet reaches the conveyer, a reciprocating operation in which the drive portion rotates the roll in the second direction in response to a leading end of the sheet reaching the first position and rotates the roll in the first direction in response to the leading end which reached the first position reaching the second position.

Examples include: a leveling system for a top feeder of a printer, where the top feeder includes a media positioning arrangement. The leveling system has a detector for detecting reflected light and generating a three-dimensional image comprising at least one media positioning region corresponding to the media positioning arrangement on a top sheet of a media stack installed into the top feeder. Also, the leveling system has an actuator configured to adjust heights of different points of the bottom of the media stack. Further, it has a controller for selecting, based on the three-dimensional image, adjustments to the heights for improving leveling of at least one of the at least one media positioning region; and controlling the actuator to implement the adjustments.
