Abstract: A paper separating roller, including a shaft body, a first friction member and a second friction member is provided. The first friction member covers a first surface of an outer periphery of the shaft body. The second friction member covers a second surface of the outer periphery of the shaft body, wherein the first friction member and the second friction member are formed of two different materials. With the design of the friction members being formed of composite materials, the paper separating roller has the advantages of two different material features at the same time, such that a wider range of performance capabilities can be achieved.

Abstract: 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.

Abstract: A rotation drive device includes a driven rotation member, a driving rotation member, a rotation relay member, a shaft, and a holder. The rotation relay member transmits only a unidirectional rotational driving force from the driving rotation member to the driven rotation member. The rotation relay member includes a housing and a cylindrical one-way clutch. A contact portion between the driving rotation member and the shaft is configured to rotate the driving rotation member and the shaft to transmit the driving force to an inner peripheral side of the cylindrical one-way clutch via the shaft. The driving rotation member includes a boss projected toward the holder and rotatably held in the holder. A portion of the shaft to support the driving rotation member and an inner wall surface of a through hole of the driving rotation member are shaped to rotate the shaft and the driving rotation member. together.

Abstract: A sheet conveying apparatus includes: a supporter having a support surface configured to support sheets; a supplier having a conveying surface exposed from the support surface and moved to supply one or more sheets; a separator including a separating roller and a retard roller located downstream of the supplier; and an inclined surface disposed upstream of the nip position and pivotable about a pivot axis. The inclined surface has a first end portion and a second end portion, and the second end portion is located downstream of the first end portion. The inclined surface is inclined such that the second end portion is nearer to the support surface than the first end portion. The first end portion is located upstream of a downstream end portion of the conveying surface. The second end portion is spaced apart from the conveying surface.
