20080290584 | Method of operating a document feeding mechanism to detect and recover from a multi-feed condition and an apparatus therefor - A method is provided of operating a document feeding mechanism having a document feed path which extends through a nip defined between an advance roller disposed on one side of a document feed path and a retard roller disposed on an opposite side of the document feed path. The method comprises detecting a multi-feed condition in which a first document and a second document overlapping the first document have been fed through the nip from an upstream end of the document feed path to a downstream end of the document feed path, and controlling operation of the advance roller and the retard roller such that the second document is driven backwards through the nip to allow the first document to be fed through the nip by itself in a non-overlapping manner without any human intervention. | 11-27-2008 |
20100019440 | Recording medium conveyer capable of effectively conveying recording medium of various types - In a recording medium conveyer, a driver drives a feeding member and a conveying member provided downstream from the feeding member in a recording medium conveyance direction independently. A controller stops driving the feeding member when a first time period elapses after a recording medium reaches the conveying member. When a selector judges that the thickness of the recording medium identifies the recording medium as thin paper, the controller does not drive the feeding member after the controller starts driving the conveying member, and when the selector judges that the recording medium has a thickness greater than a thickness of the recording medium that identifies the recording medium as thin paper, the controller restarts driving the feeding member no later than when the controller starts driving the conveying member. | 01-28-2010 |

A space where the feed roller is attached and detached is formed by rotating the detection unit. The detection unit is rotated in accordance with an operation of attaching and detaching the feed roller to and from a shaft, and the maintenance of the feed roller is performed while the formed space is used. | 03-11-2010 |
20100270729 | SPACING INTERVAL CONTROL METHOD AND SHEET LAMINATING APPARATUS USING THE SAME - A spacing interval control method is used in a sheet laminating apparatus for controlling a constant spacing interval between any two adjacent ones of multiple documents. The sheet laminating apparatus includes an automatic document feeding mechanism and a sheet laminating mechanism. By means of multiple sensors within the automatic document feeding mechanism, multiple documents are successively transported from the automatic document feeding mechanism to the sheet laminating mechanism at a constant spacing interval between any two adjacent ones of multiple documents. As a consequence, the documents after being heated or pressed by the sheet laminating mechanism will be cut into multiple separate and identical-sized laminated documents. | 10-28-2010 |

The sheet-conveyance-movement detecting unit is arranged at a position at which the outermost sheet and the next sheet may overlap each other, and a separation portion is located downstream of the pick-up position and is an area where a separation action of the separating and conveying unit works. | 05-17-2012 |
20120280445 | METHOD AND APPARATUS FOR FEEDING MEDIA SHEETS IN AN IMAGE PRODUCTION DEVICE - A method and apparatus for feeding media sheets in an image production device is disclosed. The method may include applying a downward airflow to a top of a leading edge of a media sheet located at a top of a media stack that is to be fed to an image production section of the image production device, and applying a vacuum airflow to the top of the leading edge of the media sheet located at the top of the media stack that is to be fed to the image production section of the image production device, the applied downward airflow and the applied vacuum airflow causing the top media sheet to separate from the media stack, and feeding the separated top media sheet to the image production section. | 11-08-2012 |
20130001858 | MEDIA SEPARATING AND FEEDING DEVICE AND MEDIA PROCESSING DEVICE - A mechanism enables efficiently reducing the size of a check feeding device for separating and feeding checks one at a time. In one embodiment, a check separating and feeding mechanism uses a single drive motor to drive a feed roller, pressure member, and separation roller. When the drive motor turns in a second direction, torque is transferred through a second one-way clutch mechanism to both rollers. When the drive motor turns in this direction, the first one-way clutch mechanism disengages the drive motor from the drive power transfer path to the pressure member, and a tension spring pulls the pressure member in the direction pressing the checks to the feed roller. When the drive motor turns in an opposite first direction, the torque of the drive motor returns the pressure member to the standby position, drive power is not transferred to the rollers, and the rollers do not turn. | 01-03-2013 |
20130264765 | SHEET TAKE-OUT APPARATUS WITH GAP COUNTER - A sheet take-out apparatus includes a first separation unit, a second separation unit, a drawing roller for drawing sheets from a nip of the second separation unit, and a pinch roller rotating in contact with it. Overlapping sheets which pass the first and second separation units and are not separated are detected to be overlapped in a state that they are clamped by the nip of the drawing roller and pinch roller. When overlapping is detected, in a state that the rear ends of the overlapping sheets in the conveying direction are restricted by the nip, the drawing roller and pinch roller are stopped and the overlapping sheets are re-separated. | 10-10-2013 |
