US 6,352,256 B1 · Media feeding system

Abstract

A media feeding system has a pick arm with a pick roller, a media tray, a media restrainer, a motor and a drive train. The pick arm is rotatably installed above the media tray so that it can lift the pick roller away from the media tray, and lower it onto the media tray. The media restrainer can be in an up or a down position. When in the up position, it prevents media from moving out of the media tray. When in the down position, media can move out of the media tray past the media restrainer. The drive train delivers torque from the motor to the pick arm, pick roller and media restrainer. The motor can operate in two directions. When operating in the first direction, the media restrainer moves into the down position, the pick roller lowers onto stacked media and pushes a sheet out of the media tray past the media restrainer. When the motor operates in the second direction, the media restrainer moves into the up position, and the pick arm lifts the pick roller away from the stacked media.

Dependent claims

A media feeding system for delivering media from a media tray to a medium processing apparatus, comprising:

a pick arm having a rotation pivot and a pick pivot, the rotation pivot rotatably mounted over the media tray, the pick pivot capable of rotating about the rotation pivot;
a pick roller rotatably mounted on the pick pivot of the pick arm;
a motor having a first driving direction and a second driving direction;
and
a drive train for providing torque from the motor to the pick arm and to the pick roller;
wherein when the motor operates in the first driving direction, the drive train causes the pick arm to rotate down, bringing the pick roller into contact with the media, and the pick roller rotates and pushes at least a sheet of the media in a forward direction;
when the motor operates in the second driving direction, the drive train causes the pick arm to rotate up so that the pick roller does not contact the media.

A media feeding system for delivering media from a media tray to a medium processing apparatus, comprising:

a pick arm having a pick roller rotatably mounted on a pick pivot of the pick arm, the pick roller being used to push at least a sheet of the media in a forward direction out of the media tray;
a media restrainer mounted after the media tray in the forward direction, the media restrainer being able to move to an up position or a down position;
a motor having a first driving direction and a second driving direction;
and
a drive train for providing torque from the motor to the pick roller and to the media restrainer;
wherein when the motor operates in the first driving direction, the drive train causes the media restrainer to move to the down position, and the pick roller is then able to push at least a sheet from the media tray into the forward direction past the media restrainer;
when the motor operates in the second driving direction, the drive train causes the media restrainer to move to the up position so that the media cannot move in the forward direction past the media restrainer.
