An items processing apparatus for placement and singulation of flat items has a placement device and a feed deck and a separation device. A portion of the placement device is arranged below the placement deck of the apparatus. The feed deck has an opening for an separation roller, and a portion of the separation device arranged above the feed deck. This portion and the separation roller form a gate of the separation device for the singulation of a stack of flat items. A control computer controls the placement device and separation device. The placement device is equipped for edge alignment of a stack of flat items with different formats and has at least two transport elements, which enable an automatic displacement of the stack transverse to the transport direction and placement of the stack at an alignment wall, as well as a transport of the stack in the transport direction toward the feed deck of the separation device, as well as a displacement of the stack counter to the transport direction. A movement assembly is provided to move the portion of the separation device in a direction counter to the transport direction. The control computer controls the alignment state of the transport elements of the placement device of the items processing apparatus, and controls the movement of the portion of the separation device. The aforementioned portion enables a displacement of the stack counter to the transport direction.

A roller shaft is inserted into a mold including molding members respectively having a first mold surface that defines an outer circumference of a roller portion and second and third mold surfaces that respectively define first and second flat portions of the roller portion, and the mold is then closed. A molding material is injected around the roller shaft to integrally mold the roller portion. The roller portion includes the outer circumference and the first and second flat portions rising from the roller shaft to the outer circumference. The roller shaft includes flange portions at portions corresponding to the first and second flat portions. The flange portions prevent the molding material from leaking outside the first and second flat portions when the roller portion is integrally molded around the roller shaft by injection molding.

A sheet feeding apparatus includes: a conveying roller; a separating roller which forms a nip portion by pressing the conveying roller and separates a sheet conveyed by the conveying roller one by one in the nip portion; a moving portion configured to move a stacking portion from a first position at which a sheet stacked in the stacking portion and a feeding roller are separated from each other to a second position at which the sheet stacked in the stacking portion abuts on the feeding roller; and a cover member which is movable between a third position to cover a rotation shaft of the separating roller and a fourth position to expose the rotation shaft of the separating roller, in which the cover member placed in the fourth position moves to the third position along with movement of the stacking portion from the first position to the second position.

The present invention addresses the problem of providing a bill conveying roller base having an excellent swelling resistance. In order to solve this problem, the bill conveying roller base is provided with an elastic layer covering at least part of the outer peripheral surface, the elastic layer comprising a thermosetting polyurethane which is obtained by reacting polyol components containing a lactone-based polyol with polyisocyanate components containing methylene diphenyl diisocyanate (MDI).

A feeding roller structure includes a fastening frame, a transmission component, a transmission roller and a floating coupler. The transmission component is assembled in the fastening frame. The transmission component includes a drive shaft transversely pivoted to two sides of the fastening frame. The transmission roller is concentrically arranged around the drive shaft. The floating coupler is mounted to the fastening frame. The floating coupler is coupled between the drive shaft and the transmission roller. Two opposite ends of the floating coupler are adjacent to and spaced from the two sides of the fastening frame to form two gaps. Each gap is formed between one end of the floating coupler and one side of the fastening frame. The two gaps limit an angular displacement of the floating coupler.

An image forming apparatus has: a cassette which stores a sheet; a pickup roller which picks up the sheet inside the cassette; a feed roller which feeds the sheet picked up by the pickup roller toward an image forming portion; and a retard roller which is pressed against the feed roller and forms a separation nip. In addition, the image forming apparatus has a conveying guide which guides the sheet picked up by the pickup roller to the separation nip. A first guide member of the conveying guide is configured to be slidable in a drawing direction when the feed roller is replaced, and the conveying guide is formed of a material whose property of light transmittance of light having a wavelength of 360 nm to 420 nm is 80% or more. The feed roller is detachable from the one end of a shaft in a state in which the cassette is drawn out along the rail and the conveying guide is slid in the drawing direction.

A system and method for advancing sticky media through printers includes one or more feed rollers comprised of a grit roller. The grit roller contacts an adhesive side of liner-less label stock removed from a roll or stack for printing. The grit roller works cooperatively with an opposing, counter-rotating roller to remove the label stock from the roll and feed it to a printer.

A sheet separation device includes a rotator, a nipping member to nip the two-ply sheet with the rotator, a first conveyor to convey the two-ply sheet in a first direction toward the rotator and a second direction reverse thereto, a winding member to wind the two-ply sheet around the rotator, a second conveyor to convey a sheet medium in the second direction, a separation claw to move in a width direction; a sheet guide to guide the separated two sheets to different passages; and control circuitry. The first conveyor conveys the two-ply sheet to the rotator with a bonded portion at an upstream end. The control circuitry inserts the separation claw into a space between the two sheets, adjusts a projection amount of the two-ply sheet from a nip of the first conveyor in the second direction, and inserts the sheet medium in two-ply sheet adjusted in the projection amount.

In the paper feeding roller, a shaft body has a cantilever structure supported at one end, and an elastic layer includes a supported end and a free end on both ends along a rotation axis, wherein an outer diameter of the free end in a cross section orthogonal to the rotational axis is greater than that of the supported end, and an area including the free end has a widened bottom part having an outer diameter which widens in a linear or inner convex manner approaching the free end along the rotation axis. The paper feeding device includes a feed roller rotationally driven and conveying paper, and a retard roller pressed against the feed roller, affixed with a torque limiter, and suppressing double feeding of paper. At least one of the feed roller and the retard roller is formed as the paper feeding roller.

A sheet conveyance apparatus includes a shaft portion, a roller member, and a guide member. The roller member includes a hole portion with an opening through which the shaft portion is fitted with the hole portion. At least a part of the guide member is located upstream of an end of the shaft portion in an attaching direction of the roller member. A distance between rotation axes of the roller member and the shaft portion is smaller than a difference between a radius of the opening and a radius of the end of the shaft portion in a state where an outer circumferential surface of the roller member is in contact with the guide member at a position upstream of the end of the shaft portion in the attaching direction.
