    Abstract: A safety device with two conveying systems in the sheet feeder of a machine, capable of processing a sheet-shaped material. An objective of the invention is to construct a generic sheet feeder for large-format machines so that only stacks with a specified maximum weight can reach the processing stage. The present invention encompasses a weighing device (22, 28) located in the sheet feeder (1), which determines the weight of the stack (4), is positioned on the stack carrier (3) and is connected with a regulating and controlling device (19) controlling the driving mechanism (8). At least one permissible total weight is stored in the regulating and controlling device (19). The regulating and controlling device (19) compares the weight of the stack with said stored permissible total weight and the driving mechanism (8) is activated only if the weight of the stack does not exceed the permissible total weight.

  • Patent number: 7159863
    Abstract: A method and apparatus for limiting the height of media inserted into a media tray of an image forming apparatus 10 while also allowing for the inserted media to expand due to changing environmental conditions is described herein. An exemplary stack height limiting system comprises an elongated arm with a striking end spaced from a control end, where the arm is movable between first and second positions. A limiter positioned relative to the arm defines the first position, where the striking end is spaced from the bottom surface of the tray by a first gap. As media disposed in the tray expands beyond the first gap, the expanding media moves the arm to form a second, greater distance between the striking end and the bottom surface of the tray. As a result, pinch points between the first end and the media are avoided.

  • Patent number: 7147218
    Abstract: A sheet feeding apparatus main body for containing sheets in the inside thereof includes: a first cover and a second cover which are openable and closable; and a detecting sensor for detecting an opening and closing of the first cover. The detecting sensor does not detect closing of the first cover when the first cover is closed in a state in which the second cover is opened and detects closing of the first cover when the first cover is closed in a state in which the second cover is closed.

  • Patent number: 7147219
    Abstract: A paper tray (110, 210, 310, 410, 510, 610, 710, 810) for holding a stack of sheets of paper in a printer (540, 640, 740, 840) is provided. The paper tray includes an actuator (221, 421, 521, 621, 721, 821), which is moveable between an engaged position by insertion of the tray into the printer and a refilling position by at least partial removal of the tray from the printer. A paper supporting plate (230, 330, 430, 530, 630, 730, 830) is moveably coupled to the actuator. The paper supporting plate supports the stack of paper so that a sheet furthest away from the paper supporting plate is in a picking position available for picking by the printer, when the actuator is in the engaged position. The actuator is coupled to the paper supporting plate so as to move the paper supporting plate away from the picking position when the actuator is moved into the refilling position.

  • Patent number: 7131644
    Abstract: An imaging apparatus includes a sheet separation surface positioned along the sheet feed path downstream from a media tray. A plurality of pivoting arms is mounted in the imaging apparatus. The pivoting arms are moveable between a first position and a second position. The pivoting arms are positioned and individually spaced along a width of the sheet feed path. Each of the pivoting arms has a media stack engaging surface. When the pivoting arms are in the first position, the media stack engaging surface is non-parallel to the sheet separation surface. When the plurality of pivoting arms is in the second position, the media stack engaging surface is parallel to the sheet separation surface.

  • Patent number: 7121542
    Abstract: A paper feed device includes a setting plate, a support unit, a driving unit, a power transmission mechanism, a link mechanism, and an operation lever. The support unit elevatably supports the setting plate, and elevates the setting plate when the support unit receives a driving force. The driving unit drives the support unit. The power transmission mechanism transmits the driving force from the driving unit to the support unit. The operation lever is switched between a first state and a second state. When the operation lever is in the first state, the power transmission mechanism transmits the driving force to the support unit. When the operation lever is in the second state, the link mechanism cuts off the transmission of the driving force to the support unit.

  • Patent number: 7073786
    Abstract: A paper feed has a door and a paper carrying tray, and raises the tray as paper is fed. A first detector that detects the presence of paper is located below a paper feed position by a margin corresponding to a given number of paper sheets, and second detector that detects the presence of paper is located below the first detector. If an open state of the door is detected, the paper carrying tray is lowered to a position where the second detector ceases to detect the presence of paper. If the first and second detectors detect the presence of paper after the tray is lowered, the tray is lowered to the position where the second detector ceases to detect the presence of paper. If a closed state of the door is detected after the tray is lowered, the tray is raised so that the uppermost one of paper sheets on the tray is situated in the paper feed position.

  • Patent number: 7062213
    Abstract: In accordance with the state of a document tray upon powering on a power source, the elevation operation of a document tray is controlled. In the case that the document tray is located not at the highest position, not at the lowest position, but at a middle position upon powering on the power source, the document tray is allowed to remain at the middle position as it is without performing the elevation of the document tray. In the case that the document tray is located at the highest position, the document tray is moved down. By reducing the wasteful operation (the initial operation) after powering on the power source, it is possible to reduce the operation time and the efficient sheet processing can be realized.

  • Patent number: 7021886
    Abstract: A method and system are disclosed for delivering and feeding a stack of paper to a high-speed sheet feeder. A sheet handling cart is removably connectable to a docking station attached to the high-speed sheet feeder. The sheet handling cart comprises a paper trough which is liftable from the rest of the cart. The paper trough has a trough bottom which longitudinally forms an elongated opening narrower than the bottom of the paper trough, the elongated opening being dimensioned to accommodate a conveyor belt that will protrude upward through the rectangular opening, after the paper trough is lifted from the rest of the cart, in order to advance the stack of paper toward the high-speed sheet feeder.

  • Patent number: 6880822
    Abstract: A paper feed unit includes a hopper on which sheets are stacked and which is turned around a rotation shaft. The hopper is turned to move apart from or move to a paper feed roller. The paper feed unit has three modes: a large release mode in which the hopper is turned to be most apart from the paper feed roller, a non-release mode in which the printing sheet is abutted against the paper feed roller, and a small release mode in which the printing sheet is slightly separated from the paper feed roller, and is at a medium level between the above two modes. When a paper feeding job is still present, a state that the uppermost printing sheet is slightly separated from the paper feed roller is retained by the small release mode, whereby a swing range of the hopper is minimized.
