  • Patent number: 6152309
    Abstract: A conveying arrangement includes a path selector including a selector slide that is selectively positionable at first and second positions, thereby connecting a first conveyor path with a first further conveyor path or a second further conveyor path. The selector slide is actuated by a guide arm that moves the slide from the first position to the second position, and vice versa. The selector slide is locked firmly in at least one of the positions by a locking arm that is moved to and from a locking position by the guide arm. The selector slide may have a fixed pin that interacts with a first recess or aperture formed in the locking arm, and the recess may have first and second pin-receiving end positions corresponding to the first and second positions of the selector slide. The guide arm may be pivotally mounted and have a second recess or aperture that actuates the fixed pin and a locking-arm actuating guide pin that interacts with a camming surface on the locking arm.

  • Patent number: 6145828
    Abstract: In a sheet conveying unit, two conveying sections turn linked and spaced apart such that sheet jams arising in the course of conveyance through the conveying sections can be easily cleared single-handedly. Wherein the sheet-conveying unit functions to turn over, convey and store sheets in a dual-sided copying section inside a copying machine main body (1), it may include a main frame (30) that is withdrawable frontward from the copying machine main body (1); an intermediate tray (31) storing the reversed sheets; a lower conveyor (32); an upper conveyor (33); and a linkage (34). The upper and lower conveyors (33, 32) have upper and lower conveying guides (50, 45) and upper and lower conveying rollers (51, 46), respectively, and both conveyors are open/closable on the main frame (30) disposed above the intermediate tray (31).

  • Patent number: 6131902
    Abstract: A sheet transport system for an image-forming apparatus including a scanner unit on an upper part of an image-forming unit. A paper ejecting path ejects an image formed paper sheet to an ejected paper stacker via the image-forming unit. The paper ejecting path includes a straight sheet feeding path and a turn-around sheet feeding path. A scanning sheet path conveys an original document through an original document platform to a scanned paper stacker via the scanner unit. A sheet path selector selects one of the paper ejecting path or scanning sheet path, the scanning sheet path and the paper ejecting path crossing each other. A manual paper ejecting path selector allows manually selecting one of the straight sheet feeding path and the turn-around sheet feeding path.

For each object, a code associated with that object is determined, which code is stored in accordance with the order of receipt of the objects. Each object that is discharged is scanned and the scanning result is compared with a code that on the basis of order information is supposed to be associated with that object. If a particular minimum extent of agreement between the compared data is found, a normal operating status is adhered to. If less than the particular extent of agreement between the compared data is found, an error message status is selected.

  • Patent number: 5971393
    Abstract: The present invention relates to a device and a method for unloading a sheet medium from a vacuum drum which may be a vacuum drum of an imagesetter for example, or a vacuum drum of an input scanning machine. The unloading is facilitated by the stiffness of sheet medium. When the vacuum holding a sheet medium is released, the stiffness of the sheet medium causes the sheet to separate from the drum. A roll forces the sheet onto the drum and the motion of the drum forces the sheet medium onto a table which has been moved into proximity of the drum. The sheet travels onto a transport mechanism which eventually takes over the moving of the sheet medium without requiring synchronism between the drum rotational speed and the transport mechanism.

When a sorting mode is selected, papers are ejected from the sorting exit to the sorting bins each of which faces to the sorting exit by sequentially shifting the bin assembly. In this operation, the non-sorting bin is kept stationary while the papers are ejected to the upper sorting bins, and the non-sorting bin is shift together with the sorting bins while the paper are ejected to the lower sorting bins.

  • Patent number: 5931454
    Abstract: A recycle document feeder according to the present invention includes a cover (251) covering a document discharge portion (30). The cover (251) is openably supported by a pivot shaft (256) between a pair of frames (255). A feed-back path (32) for guiding a document original onto a document placing plate is defined by a pair of guide members (257, 258) provided in an opposed relation. The upper guide member (258) is attached to the interior face of the cover (251). A switch claw (253) for switching the document traveling direction is attached to the pivot shaft (256) which supports the cover (251). Thus, there is no need for additionally providing a shaft for supporting the switch claw (253), thereby simplifying the construction of the document discharge portion (30).

  • Patent number: 5924688
    Abstract: A reversing device for at least one sheet of paper, intended particularly for inclusion in a scanner in a printing device such as a printer or a copying machine. The reversing device has a first guide for guiding one or more paper sheets along a feed path in a first direction. A roller system is also provided and is disposed downstream from the first guide. The roller system defines a transport nip and comprises at least one driven roller which is adapted to be driven selectively in two opposite directions of rotation for selectively driving the sheet of paper respectively in a second direction and a third direction. The second direction has a component which is in the first direction, and the third direction is opposite to the first direction. A second guide is also provided for guiding the paper sheet in a fourth direction which has a component in the third direction. When moving in the fourth direction, the paper sheet moves along a discharge path which is different from the feed path.

    Abstract: The sheets in each tray of a multi tray sheet feeder are of the same thickness, but the sheets in one tray may be of a different thickness than the sheets in another tray. The sheets are fed from each sheet feeder tray to an intermediate stacker and then to a printer. A first sensor is provided just prior to entry of a sheet into the intermediate stacker and a second sensor is provided to sense a sheet as it is fed from the intermediate stacker. If the paper weight of sheets of paper on a tray fall within a first range of paper weight values, each sensor is designed to have a first given voltage response condition when sensing those sheets and if the paper weight of the sheets falls within a second range of paper weight values each sensor is designed to have a second given voltage response condition sensing the latter sheets.

    Abstract: A sheet feed sensor is designed to have a first given voltage response condition for sensing sheets within a first range of paper weight values and a second given voltage response condition for sensing sheets within a second range of paper weight values. A current value supplied to the emitter of the sensor can be controlled to provide the desired voltage response or a resistance in a phototransistor collector circuit can be varied to provide the desired voltage response condition. If the first range of paper weight values is lighter than the second range of paper weight values, the sensor, when in the first given voltage response condition, will have a voltage response, when sensing a sheet of a given paper weight, which is higher than the voltage response when the same sensor senses a sheet of the same paper weight, when the sensor is in the second given voltage response condition.
