    Abstract: A transporting device sends a sheet with the rotation of a first drive roller with the sheet sandwiched between a first drive roller and a driven roller. The sheet is sent to a direction to which a back surface thereof is pressed against a guide surface, and is transported to a second drive roller in a state of being pressed against the guide surface after the guide surface pushing and bending a transport path toward a front surface side. A lifted amount of the sheet from the guide surface is monitored by a sensor, and the transportation is stopped in a case where the lifted amount is equal to or larger than a predetermined amount.

While the media sheet is moving, a first sensor is activated with the media sheet and then a second sensor is activated with the media sheet. Feedback is received by a processor indicating the number of rotations of the at least one roller. A measured distance DM from the first sensor to the second sensor is calculated. An adjusted distance DA from the second sensor to a feed nip is then calculated. After activation of the second sensor, the roller continues to move the media sheet on the media path and the roller is rotated at least the adjusted distance DA.

The system is configured to use pressurized air to transport a card inserted to a conveying duct inside a card passageway assembly from a first end to a second end. Air nozzles are configured to release the pressurized airstreams at an angle relative to the conveying duct so that the card is essentially floating when traveling along the conveying duct. Hence, the card makes zero or minimum contact with the inner surface of the conveying duct. This will not only reduce the wear and tear of the card, but also reduces the traveling time inside the conveying duct.

The control section controls the roller first driving motor, in a case where the delay in the sheet carrying is detected by the carrying delay detecting section, so that (i) the pickup roller once stops and then restarts rotating and (ii) a start-up acceleration of the pickup roller, which start-up acceleration is an acceleration from the restart of rotation to arrival at a predetermined speed, becomes lower than a first start-up acceleration from start of rotation of the pickup roller to arrival at the predetermined speed in a case where there is no delay in the sheet carrying.

  • Publication number: 20100156026
    Abstract: An apparatus and method are described in which documents and enclosures are fed by feeding stations to a supply track and subsequently transported along the supply track to a gathering station. A sensor downstream of the feeding stations is used for scanning markings. A divert station connected to the supply track allows clearing the supply track, when scanned markings indicate that the first sheet of a next set has been scanned in the supply track, by diverting the first sheet to the divert station. This allows enclosures of the set being gathered to be fed along the supply track and gathered at the gathering station. After the completed set has vacated the gathering station, the diverted sheet is transported to the gathering station and gathered with further documents of the next set.

  • Publication number: 20100092189
    Abstract: A sheet is placed on a sheet feed unit. A main-scanning sensor detects first detection information for identifying a sheet size in a main-scanning direction and a sub-scanning sensor detects second detection information for identifying a sheet size in a sub-scanning direction. A sheet sensor detects presence of the sheet on the sheet feed unit. It is monitored whether the sheet sensor has detected a sheet and a timer starts counting a first elapsed time from a time point at which the sheet sensor detects a sheet. A size identifying unit identifies, when the first elapsed time exceeds a first predetermined set time, a sheet size based on the first and the second detection information.

  • Patent number: 7396009
    Abstract: Methods and devices for moving a media sheet along a media path from an input area to a toner transfer area. One method comprises initially determining that the media sheet is to be moved from the input area. After making the determination, the media path is detected to ensure it is capable of moving the media sheet. If the media path is available, the media sheet is picked and moved along the path. If the media path is not available, the media sheet remains in the input area until the path is available. When required to wait for the path, an amount of delay is determined. Once the path is available, the delayed media sheet is picked from the input area and then accelerated to compensate for the delay.

  • Patent number: 6729613
    Abstract: One method operates a pick motor and a separate feed motor to pick and feed a sheet for printing. Desired pick and feed motor velocities are obtained from respective first and second functions of sheet position. Sheet position for obtaining both desired motor velocities is determined by the pick system until a predetermined event. The feed-system sheet position is synchronized to the pick-system sheet position upon the happening of the event. Sheet position for obtaining both desired motor velocities is determined by the feed system after the event. Another method operates a printer pick motor and includes starting picking by driving the pick motor in a first direction, to move a sheet forward, with an input sufficient to prevent any teetering transitions between peaks and valleys of an encoder sensor output which would be falsely counted as forward motion by a single-channel encoder.
