Abstract: The impact sound when a sheet member forms a loop is reduced so as to make the apparatus less noisy. A speed control device is provided for making the transport speed when the sheet member is made to hit a first transport device by a second transport device relatively slower than that of the first transport device. By changing the amount of transport of the first transport device along the width of the sheet member at right angles to the transport direction of the sheet member, the loop is formed successively along the width of the sheet member.

Abstract: An automatic original document feeding device which can shorten a length of time required for refeeding sheets of the original document after a jamming of a sheet of the original document is cleared. When a trouble signal is received indicating that a sheet of the original document remains within a feed path due to an improper feeding or a jamming before the sheet is completely scanned, a side cover is opened and at the same time a driving mechanism is actuated for automatically lowering the sheets of the original document from a feeding position. If the jamming occurs at a later position in the paper path after the image has been completely scanned, the side cover does not have to be opened, the driving mechanism is not lowered, and the sheets of the original document remain in their feeding position.

Abstract: Disclosed is a paper feed mechanism in which copy paper stacked on a paper support member such as a manual insertion tray is fed along the sheet transport direction in a nipped state between an upper roller and a lower roller. The upper roller has, on its outer surface in the described order with respect to the rotational direction, a non-contact area which is not brought into pressing contact with the copy paper and the lower roller, a first contact area which comes into pressing contact with the copy paper and the lower roller and whose frictional coefficient relative to copy paper is set small, and a second contact area which comes into pressing contact with the copy paper and the lower roller and whose frictional coefficient relative to copy paper is set large. The lower roller is mounted on a torque limiter.
Abstract: An optical inspection system inspect products passed through an inspection region. Light is directed onto the products form optical control units including light emitting diodes. Light emitted from the diodes is directed by cylindrical lenses onto the products at a specified target region, and a sensor detects light reflected from the products. Focussing is achieved by an outer row of the diodes being displaced outwardly relative to axes of respectively cylindrical lenses, so that light originating from the outer rows of diodes converges towards that passing along a central axis extending from a central row of the diodes through a central lens to the target region, light from all rows of the diodes being therefore focussed substantially at the target region.
Abstract: A small-size apparatus for sorting sheets or the like can form a delivery route by repeating sorting operation and prevent an overflow of sheets or the like. To this end, auxiliary sorting compartments are provided in accumulating means in the sorting operation for the first time, and when an overflow occurs, the allocated sorting compartments are shifted each by one compartment to the side of the auxiliary sorting compartment. In the first-time sorting operation, destination codes 15 and thicknesses are stored in memory, and by the destination codes and thicknesses stored, overflow is predicted, a plurality of sorting compartments are allocated. By this arrangement, the sheets or the like can be prevented from overflowing, so that those sheets or the like which are rejected need not be manually added afterwards, and the efficiency of the sorting work can be improved.
Abstract: An apparatus and method of synchronizing entry of a mailpiece from a mail feeder into a designated mailpiece location of a mail sorting conveyor. The method includes the steps of establishing a symmetric speed versus time profile around a send signal. In a first case, when the mailpiece stops before receiving the send signal, the method further includes following the speed versus time profile to accelerate to a merge speed for merging the mailpiece with the designated mail location of the sorting conveyor. In a second case, when the send signal arrives before the mailpiece reaches the stop position, holding the mailpiece at a constant speed across the speed versus time profile until the position of the mailpiece intersects an opposing side of the speed versus time profile and then following the speed versus time profile to accelerate the mailpiece to a merge speed for merging the mailpiece within the designated mail location of the sorting conveyor.

Abstract: The present invention relates to an input system for feeding one-up sheets from a paper web to a high speed mass mailing inserter system. The input system includes a feeding module for supplying a paper web having two web portions in side-by-side relationship. A merging module is located downstream in the path of travel from the feeding module and is operational to feed the two web portions in an upper-lower relationship so as to reorient the paper web from the side-by-side relationship to an upper-lower relationship. A separating module is located downstream in the path of travel from the merging module and is operational to receive the paper web in the upper-lower relationship and separate the paper web into individual two-up sheets. In order to separate the two-up sheets into one-up sheets, a stacking module is located downstream in the path of travel from the separating module and is configured to receive the two-up sheets, stack the two-up sheets and individually feed one-up sheets from the stack.

Abstract: A sorter mailbox has a sheet transport for moving sheets through a feed path to a set or sets of vertically spaced receiver trays having sheet deflecting gates which are actuated so as to sowing toward or into an open sheet deflecting position so as to contact with light spring pressure a sheet moving through the sheet feed path but to open to deflect the sheet into a selected tray from the sheet feed path.
Abstract: An apparatus for separating a mixed granular material into granules of different specific gravities or ranges of specific gravity using a powered air flow is described. A divider plate is located below the air flow path within the apparatus to separate the two material flows from each other. The divider plate can be rotated about an axis and can also be translated or displaced within the apparatus in order to precisely define the separation point between the material flows. Hoppers are used to collect and discharge the separated granular materials, and a conveyor belt is provided within the apparatus to transport one of the separated granular materials to the corresponding hopper. The conveyor belt reduces clogging of the separated granular material and also allows a greater degree of separation to be maintained between the hoppers, thereby allowing standard conveyors to be placed beneath the hopper discharge openings.
