Claims9
A document transport arrangement in a high speed encoder wherein unit-record documents are transported along a path past at least one encoder process-station according to one, or several, "velocity-profiles", depending upon the type and/or condition of each said document, this arrangement including:
- sensor means disposed along said path and adapted to detect and indicate passage of a document;
- plus control means for controlling document advance, for selecting and setting-up at least one "document-velocity-profile" to be invoked as a function of the sensed condition and the sensed position of each document along this path, and for also deriving data indicating one or several characteristics for each such document thereby to monitor progress of each document along said path so that, when a prescribed point is reached, said control means may then invoke a corresponding segment of the selected velocity profile, according to one or more of said document characteristics;
- and dog-ear detector means adapted to detect documents having a dog-ear condition and indicate this to said control means whereby dog-eared documents may be automatically advanced through said process station without stopping for encoding.
A document-transport control arrangement in a high speed encoder wherein documents are guidedly-advanced along a prescribed linear path, past one or more encoder processing-stations, while being monitored by passage-sensor means, this control arrangement serving to control document-advance and comprising:
- microprocessor means setting-up at least one "document-velocity-profile" to be invoked as a function of sensed position along this path and also recording one or several profile-related characteristics for each type of document contemplated;
- detect means including dog-ear detector means adapted to detect documents having a dog-ear condition and indicate this to said control means whereby dog-eared documents may be automatically advanced through said process station without stopping for encoding disposed along said path and adapted to detect said other characteristics and indicate them to said microprocessor means;
- and
- decision means for monitoring progress of each document along said path wherein, when a prescribed decision point is reached, said decision means invokes a corresponding segment of said velocity profiles in said microprocessor means according to at least one of said document characteristics.
A controlled transport arrangement in a document encoder whereby unit-record documents are controllably transported past at least one encoder process-station according to one, or several, "velocity-profiles", depending upon the type and/or condition of the document, this arrangement including:
- document-transport means for guidedly-advancing the documents along a prescribed linear path, past said one or more encoder process-stations;
- at least one passage sensor means for monitoring document passage;
- microprocessor means for controlling document-advance and for setting-up at least one "document-velocity-profile" to be invoked as a function of the sensed position of each document along this path;
- said microprocessor means also deriving data indicating one or several characteristics for each such document whereby to monitor progress of each document along said path so that, when a prescribed point is reached, it may then invoke a corresponding segment of said velocity profiles, according to at least one of said document characteristics;
- and dog-ear detector means adapted to detect documents having a dog-ear condition and indicate this to said control means whereby dog-eared documents may be automatically advanced through said process station without stopping for encoding.
