Abstract: A recording medium conveying device for an image forming apparatus of the present invention includes a conveying member for conveying a sheet or similar recording medium by nipping it. After the sheet being conveyed by the conveying member has abutted against a registering member, the registering member rotates in synchronism with the rotation of an image carrier carrying an image thereon for thereby conveying the recording medium toward an image transfer position. After the recording medium has slackened on abutting against the registering member, a nip canceling mechanism cancels the nip of the conveying member acting on the recording medium.

Abstract: A sheet feeder includes a sheet mounting plate, pick-up roller, drive motor and transmission device to prevent an excessive load from being applied to a pick-up roller when no sheets are mounted on a sheet mounting plate. When the sheets on the sheet mounting plate run out, a sheet detecting actuator of the sheet feeder fits into an opening formed on the sheet mounting plate. Accordingly, a protrusion of a drive actuator slides along a groove formed on the sheet detecting actuator, which causes the drive actuator and a drive interrupting boss to move. With this structure, transmission of drive force to the pick-up roller is interrupted.

The port plate includes ports wherein the air flow through some of the ports is restricted by an intermediate plate positioned within the plenum which, in turn, has a restrictive passage therein through which air from the restricted ports must flow into the plenum.

Abstract: A currency evaluation device for receiving a stack of currency bills and rapidly evaluating all the bills in the stack. The device includes an input receptacle for receiving a stack of bills to be evaluated and a single output receptacle for receiving the bills after they have been evaluated. A transport mechanism transports the bills, one at a time, from the input receptacle to the output receptacle along a transport path. The device further includes a discriminating unit that evaluates the bills. The discriminating unit comprises two detectors positioned along the transport path between the input receptacle and the output receptacle. The detectors are disposed on opposite sides of the transport path so that they are disposed adjacent to opposite sides of the bills. The discriminating unit counts and determines the denomination of the bills. The evaluation device also includes means for flagging a bill when the denomination of the bill is not determined by the discriminating unit.

Abstract: A method and system for correcting paper registration skew. A skew or paper registration error of a sheet moving in a feed path is detected. A coarse adjustment, or copy paper registration, using full steps is performed until the registration error is reduced to a minimum value, below a full step. The frequency of one motor with respect to the other, or a reference, or reference motors, is adjusted for a fixed period to enable a fine adjustment to correct the registration error.
