Abstract
Abstract An improved paper feed arrangement wherein a low vertical profile is attained through utilizing trained power driven belts (20, 22, 24) for picking paper (14) from a hopper (12), and wherein picking reliability is enhanced both by the broad-expanse area contact offered by such belts (20,22, 24), and by a unique coefficient to friction differential area downstream from a hopper (12) wherein inadvertently plural picked paper sheets (14) are easily separated.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
70 words
For incorporation in a printer (8) and the like, a low-profile, enhanced-reliability paper-feed arrangement comprising: paper-storage hopper structure (12) including a discharge zone (12 a ), and broad-expanse, power-driven, traveling pick means (20, 22, 24) disposed adjacent said discharge zone (12 a ) operable, with paper (14) stored in said hopper structure (12), to pick such paper (14) through the action of generally quadrilinear, broad-area facial contact with the same.
Claim 2
Dependent Claim
18 words
The arrangement of claim 1, wherein said pick means comprises at least one power-driven belt (20, 22, 24).
Claim 3
Dependent Claim
29 words
The arrangement of claim 2 which further includes a low-profile idler (26) training a reverse-bend reach of said belt (20, 22, 24) over said discharge zone (12 a ).
Claim 4
Dependent Claim
50 words
The arrangement of claims 2 or 3 which further comprises an expanse of frictioning means (18) facing a run in said belt (20, 22, 24) downstream from said discharge zone (12 a ), adapted for facial contact with a sheet of paper (14) picked by the belt (20, 22, 24).
Claim 5
Dependent Claim
53 words
The arrangement of claim 4 which is designed in such manner that the nominal coefficients of friction expected to exist between paper (14) and belt (20,22,24) (PB), between paper (14) and paper (14) (PP), and between paper (14) and frictioning means (18) (PF) are different, with PF exceeding PP, and PB exceeding PF.
