    摘要: A sheet transport apparatus picks up and transports a topmost sheet of a stack of sheets in a one-by-one manner. A suction drum with a cylindrical member rotating in a cyclic manner picks up the leading edge of the topmost sheet by suction force when the cylindrical member is substantially in a momentary stop state. A stationary separation suction head disposed adjacent the stack in the transport direction separates by suction force any sheets underlying the topmost sheet undesirably picked up by the operation of picking the topmost sheet from the stack. A belt conveyor system disposed adjacent the stationary separation suction head in the transport direction gradually grasps the leading edge of the sheet picked-up by the suction drum while the trailing portion of the grasped sheet is also attracted by the suction drum means so that a slight tension is given to the sheet until it is firmly held and transported by the belt conveyor system.

    摘要: Document transport apparatus in a document reader sorter is provided with a vacuum assisted friction feeder for picking documents one at a time from a document hopper and for advancing the documents at high speed along a document transport guideway to the control of a transport burst roller, the picking of the documents from the hopper by an apertured friction feed belt being assisted and facilitated by a low pressure vacuum directed upon a linearly disposed section thereof adjacent the hopper, and the high speed advancement of the documents into and along the document guideway to the control of the transport burst roller being assisted and facilitated by a high pressure vacuum directed upon a curvilinear section of the apertured belt cooperably disposed relative to the apertured circumference of a drive pulley, said high pressure vacuum being effective to lock the picked documents and particularly the leading edges thereof to the feed belt for an accelerated feeding thereof, said accelerated feeding of the documents into the document transport guideway in combination with the accelerated transmission of the documents therein by the transport burst roller resulting in maximized document throughput for the document reader sorter.

    摘要: A ported belt type single sheet feeder having a variable speed drive transmission between means for driving the belt and a rotary valve controlling application of subatmospheric pressure to a shoe behind the ported belt to permit variation of the frequency of application of the subatmospheric pressure in the shoe relative to the speed of the drive of the belt so as to vary the spacing of sheets drawn onto the belt.
