A retaining member has annular inner and outer circumferential portions, a connection portion, engagement projections, a slit, a grip portion, a first inclined surface, and a second inclined surface. The engagement projections projects from a shaft-facing surface of the inner circumferential surface. The slit is formed in the inner circumferential portion. The grip portion projects outward in the radial direction from an outer rim of the outer circumferential portion. The first inclined surface is formed at an upstream-side end part of the grip portion with respect to a direction of fitting to the shaft to be inclined outward in the radial direction from upstream side to downstream side in the fitting direction. The second inclined surface is formed at a downstream-side end part of the grip portion to be inclined outward in the radial direction from downstream side to upstream side in the fitting direction.

A media diverter of a valuable media depository includes two integrated divert gates, each divert gate controlled by a separate stepper motor. The integrated divert gates are enclosed by two pivoting skid plates and two fixed skid plates. The stepper motors selectively position the integrated divert gates to define a media path for a media item from a source depository module to a destination depository module through the media diverter. In an embodiment, each of the two pivoting skid plates are adapted to be unlatched on one end to expose and provided access to different media paths for purposes of servicing media jams within the media diverter.

An image reading device includes a first roller that is rotatably supported by a frame, a second roller that is supported by the frame in a rotatable and translatable manner and that presses a medium against the first roller, a joint unit that transmits rotation from a drive shaft to the second roller, a drive unit that rotates both the first roller and the drive shaft, and a read unit configured to read an image on a conveyed medium that is conveyed by the rotation of the both of the first roller and the second roller.

A recording apparatus includes a recording head that performs recording; a feeding roller that feeds out a medium that has been set, a transport roller that transports the medium fed out by the feeding roller toward a facing position facing the recording head; an auxiliary roller that is provided between the feeding roller and the transport roller and that assists in the transport of the medium; a motor that generates a driving force; and a drive train that is configured to transmit the driving force of the motor to the auxiliary roller and the transport roller.

A drive transmitting device, which is included in an image forming apparatus, includes a drive source, a drive transmitting body, and a rotary shaft. The drive transmitting body has a press-in target portion. The rotary shaft includes a press-in portion mounted on one end of the rotary shaft in an axial direction of the rotary shaft to be pressed into the press-in target portion of the drive transmitting body. The press-in portion includes a flat face and a plurality of circular arc faces having different distances from an axial center of the rotary shaft and being disposed at a same position as at least a portion of the flat face in the axial direction of the rotary shaft. A radius of curvature of one of the plurality of circular arc faces is greater than a radius of curvature of another of the plurality of circular arc faces.

A drive mechanism that drives a rotator to rotate includes a main motor, an assist motor, and processing circuitry. The main motor drives the rotator. The assist motor drives the rotator and assists a drive of the rotator by the main motor. The processing circuitry controls a speed of the main motor so that a rotational speed of the rotator is constant, and controls a motor voltage of the assist motor so that the motor voltage of the assist motor changes according to a change in a motor current of the main motor.

A method for winding a material sheet, in particular a plastic film, by a winding device, wherein the material sheet is guided from at least one first roller to at least one second roller in a conveying direction. At least one cutting device is arranged between the first roller and the second roller to cut the material sheet into at least two partial sheets. The partial sheets are each wound up into a bobbin in the conveying direction behind the second roller. The at least one first roller and the at least one second roller are each driven by a drive so that the tensile stress in the material sheet or in the partial sheets changes periodically over time in the conveying direction of the material sheet.

A presentation device for presenting a ticket from a printer includes first and second reels, a ticket holder and a housing component. In operation, the first reel contacts a first side of the ticket, and the second reel contacts a second side of the ticket opposite to where the first reel contacts the first side of the ticket. As the ticket advances from the presentation device, gravity pushes the ticket down onto the ticket holder, which is a reel. The first reel, the second reel and the ticket holder are secured in the housing component. The housing component is pivotable about a rotating axis and has a supporting notch that supports the second reel. The supporting notch has a first guide edge surface that faces away from the rotating axis, a second guide edge surface, and a trough between the first guide edge surface and the second guide edge surface.

A registration system for a printing device and a method for controlling the same are disclosed. For example, the registration system includes at least one sensor to detect a position of a print media, a platform comprising at least one multi-rotational wheel, and a processor communicatively coupled to the at least one sensor and the at least one multi-rotational wheel, wherein the processor calculates a desired movement of the at least one multi-rotational wheel based on the position of the print media.
