Abstract: A controller controls a floating unit and a conveyor to convey a sheet to a supply destination, and performs a following control of acquiring a detection value of a detector which detects an output signal acquired due to an input to a side of a sheet stack, during floating of sheets floated by the floating unit each time a sheet is conveyed by the conveyor and lifting a stacking tray upon the acquired detection value being less than a threshold value. The controller controls the floating unit and the conveyor to perform a feeding retry upon an occurrence of empty feeding in the conveyor, and determines the threshold value such that a target position for a height position of an upper surface of the sheet stack in the following control is a position where empty feeding is more likely to occur than multiple sheet feeding in the conveyor.

Abstract: A discharge of paper or other leaves from the top (S) of a stack is by a rotating feed-roller (17;41) mounted on a carrier (7,11;35-39) that moves progressively along the stack in maintaining the roller (17;41) engaged with the top leaf. The carrier (7,11;35-39), which has a slot-mouth (8;52) through which the leaves are discharged successively by the roller (17;41), is guided in its downward movement by side-wall slots (12;40) of a casing (2;32) holding the stack, and has counter-balancing weights (23;50) attached for adjustment of the pressure of the roller (17;41) on the stack. In one form, the carrier is mounted on a plate which carries a motor for belt-drive to the roller, and which has sliding pivotal movement in the casing to enable the carrier to follow the guide-slots. Alternatively, the motor is located within the roller and ears of brackets on the carrier are located in the guide-slots to hold the carrier from tipping.

Abstract: A printing system sheet feeder apparatus and method is provided. The printing system feeder includes a front nudger roll positioned near the leading edge of the top sheet of a sheet stack and the front nudger roll is capable of advancing the top sheet. In addition, the printing system sheet feeder includes a separation nip aligned with the front nudger roll, the front nudger roll being capable of receiving the top sheet advanced by the front nudger roll and advancing the top sheet in a direction away from the front nudger. A rear nudger roll is positioned near the trailing edge of the top sheet and is capable of advancing the sheet directly below the top sheet while the top sheet is being advanced by the front nudger roll and/or separation nip, thereby increasing the overall sheet feeding rate to the printing system.

Abstract: Techniques are disclosed for supporting objects in a tray and moving different portions of the objects at different rates for inputting or outputting from an objects processor. These techniques may be applied to stacking objects that has a thickness at one end greater than the thickness at another end, for example, resulting in stacking height of the thicker end increasing faster than the stacking height of the other thinner end.

Abstract: Disclosed herein is a sheet feeder for a printer. The sheet feeding device feeds a single sheet into an infeeder of a printer without communicating with the printer. The sheet feeder is equipped with a sensor for detecting when the printer is able to accept a sheet. The sheet feeder is equipped with a programmable timing device that causes the sheet feeder to wait a predetermined amount of time before inserting another sheet into the printer. The predetermined amount of time corresponds to the amount of time needed for the printer to complete printing on a sheet after the sensor has detected that the printer is able to accept a sheet into the infeeder of the printer. The sheet feeder is configured with a gate having an adjustable gap in close proximity to a tray containing a stack of sheets. The gate permits only a single sheet to be fed into the infeeder of the printer at a time. The gate has a guide post having a radius of curvature curving toward the gap to urge the stack of sheets toward the gap in the gate. The sheet feeder has an adjustable tray designed to compensate for non-uniform profiles of a stack of sheets. The adjustable tray urges the stack of sheets into the gap in an upward motion to prevent jamming of the sheets in the sheet feeding device.

Abstract: A dispenser for dispensing flexible media such as cut sheets (1) from a stack has a rotatable separating member (4) which engages and reverse buckles one end of the top sheet (2) so that that end is lifted away from the stack and positioned between transport rollers (9, 10). The transport rollers (9, 10) are driven independently from the separating member (4) so that multiple sheets may be separated from the stack before being transported. The frictional engagement between the separating member (4) and the stack varies as the separating member rotates, so that only one sheet is separated with each rotation. The center of the top sheet (2) is held against the stack by a holding member (3) so that the top sheet buckles only over part of its length.

Abstract: A printer comprises a feeding device and a printing device. The feeding device has a substrate, a linkage mechanism, a deskewer, a recovery device and a scrubber. The linkage mechanism is disposed on the substrate and has a pallet used to support the media and moving between an initial site and a predetermined site in parallel. The deskewer is used for deskewing the media located on the pallet, the recovery device is disposed on the linkage mechanism, and the scrubber for feeding the media located on the pallet toward the printing device. Once the media is placed between the pallet and the scrubber or gradually delivered to the printing device by the scrubber, the pallet of the linkage mechanism is downwardly or upwardly shifted in parallel by the compressed recovery device.

Abstract: An inexpensive paper folding machine includes a paper feeder that reliably propels sheets one at a time in a downstream direction. The feeder includes a paper supply station that biases a stack of sheets against a pickoff wheel. The pickoff wheel propels the topmost sheet to a gate tip. The gate tip is comprised of a singulator that is biased against the pickoff wheel. A clearance is set between a singulator screw and the singulator. The clearance is greater than the sheet thickness, but less than two times the sheet thickness. As a sheet is propelled by the pickoff wheel from the paper supply station, the sheet leading edge enters the nip between the pickoff wheel and the singulator. The singulator pivots to take up part of the clearance. If a second sheet is propelled with the topmost sheet, the second sheet cannot pass between the nip. The paper folding machine further comprises a skew compensator that compensates for sheets that are misoriented relative to the downstream direction. In a modified embodiment, a relatively soft pickoff wheel is used, and the clearance is less than the thickness of a sheet. The pickoff wheel is compressed as the sheet passes through the nip between the singulator and the pickoff wheel.
