Abstract
Abstract A processing input and output apparatus wherein a paper member bearing input data is transported along a path from the input of the apparatus to the output thereof by cooperating endless belts supported on crowned rollers and driven frictionally by a drive wheel in a sprocketless assembly. During the movement through the apparatus, the paper is sensed, read and printed upon.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
218 words
An apparatus for transporting and processing data bearing paper sheets comprising: a. a paper sheet transport including first and second groups of crowned rollers, a drive wheel having a peripheral frictional engagement surface, first and second endless sprocketless belts, each having an inside and outside surface thereof, the inside surface of said first belt cooperatively engaging said first group of crowned rollers and the peripheral surface of said drive wheel, the inside surface of said second belt cooperatively engaging said second group of crowned rollers, portions of the outside surfaces of said first and second belts being in frictional engagement whereby an input end and output end of said engaged belt portions are formed; b. first and second optical detectors substantially adjacent the input end and output end respectively of the portions of said first and second belts in frictional engagement with one another; c. a printer substantially adjacent to said second optical detector and opposite from said engaged belt portions whereby said paper sheet is printed upon after being output from the output end of said engaged belt portions and detected at said second optical detector; and d. first and second motors coupled to said drive wheel, said first and second motors being alternately operated to rotate said drive wheel in a forward and reverse direction respectively.
Claim 2
Independent Claim
218 words
An apparatus for transporting and processing data bearing paper sheets comprising: a. a paper sheet transport including first and second groups of crowned rollers, a drive wheel having a peripheral frictional engagement surface, first and second endless sprocketless belts, each having an inside and outside surface thereof, the inside surface of said first belt cooperatively engaging said first group of crowned rollers and the peripheral surface of said drive wheel, the inside surface of said second belt cooperatively engaging said second group of crowned rollers, portions of the outside surfaces of said first and second belts being in frictional engagement whereby an input end and output end of said engaged belt portions are formed; b. first and second optical detectors substantially adjacent the input end and output end respectively of the portions of said first and second belts in frictional engagement with one another; c. a printer substantially adjacent to said second optical detector and opposite from said engaged belt portions whereby said paper sheet is printed upon after being output from the output end of said engaged belt portions and detected at said second optical detector; and d. first and second motors coupled to said drive wheel, said first and second motors being alternately operated to rotate said drive wheel in a forward and reverse direction respectively.
Claim 3
Dependent Claim
105 words
An apparatus as defined in claim 1 including a motor control circuit comprising: a. first and second binary switching means for registering forward and reverse motor rotation respectively; b. a pair of thyristors each having an input and output terminal and a gate terminal, each of said gate terminals being coupled to one of said binary switching means and each of said output terminals being Connected to a respective one of said first and second motors; and c. means for connecting said second binary switching means and said second motor coincident with forward rotation whereby the forward rotation of said drive wheel is rapidly halted.
Claim 4
Dependent Claim
18 words
An apparatus as in claim 1 wherein said first and second endless sprocketless belts are rubber sprocketless belts.
Claim 5
Independent Claim
236 words
An apparatus for transporting and processing a data bearing paper form comprising: a. first and second optical readers; b. a paper form transport comprising: i. a first and second group of crowned rollers; ii. a drive wheel having a peripheral frictional engagement surface; iii. first and second endless sprocketless belts each having an inside and outside surface thereof, the inside surface of said first belt being symmetrically disposed upon and cooperatively engaging said first group of crowned rollers and the peripheral surface of said drive wheel, the inside surface of said second belt being symmetrically disposed upon and cooperatively engaging said second group of crowned rollers, a portion of said outside surfaces of said first and second belts being in frictional engagement for a distance substantially extending from said first optical reader to said second optical reader; iv. first and second motors cooperatively coupled to said drive wheel, alternately operated to rotate said drive wheel in a forward or reverse direction to move the paper form from said first optical reader to said second optical reader and from said second optical reader to said first optical reader respectively; c. a printer disposed substantially adjacent said second optical reader whereby said paper form is printed upon after detection thereof; and d. control means for positioning the paper form at said printer, said control means coupled to said first and second optical readers, said transport and said printer.
Claim 6
Independent Claim
236 words
An apparatus for transporting and processing a data bearing paper form comprising: a. first and second optical readers; b. a paper form transport comprising: i. a first and second group of crowned rollers; ii. a drive wheel having a peripheral frictional engagement surface; iii. first and second endless sprocketless belts each having an inside and outside surface thereof, the inside surface of said first belt being symmetrically disposed upon and cooperatively engaging said first group of crowned rollers and the peripheral surface of said drive wheel, the inside surface of said second belt being symmetrically disposed upon and cooperatively engaging said second group of crowned rollers, a portion of said outside surfaces of said first and second belts being in frictional engagement for a distance substantially extending from said first optical reader to said second optical reader; iv. first and second motors cooperatively coupled to said drive wheel, alternately operated to rotate said drive wheel in a forward or reverse direction to move the paper form from said first optical reader to said second optical reader and from said second optical reader to said first optical reader respectively; c. a printer disposed substantially adjacent said second optical reader whereby said paper form is printed upon after detection thereof; and d. control means for positioning the paper form at said printer, said control means coupled to said first and second optical readers, said transport and said printer.
Claim 7
Dependent Claim
34 words
An apparatus as defined in claim 4 wherein said control means comprises means for superimposing the rotation of said first and second motors whereby the forward motion of said drive wheel is rapidly halted.
