from one another such that the positioner is lifted by the curved portions of the lower portions as the lower portions move upward and toward one another as the ring positioner 40 is stiff enough so that when holes 52 54 inward 62 sections 64 66 are in contact with concave arcuate surfaces 68 70 of segments 44 46 so that the inward sections are cammed upward by the upwardly and inwardly 58 moving lower portions 42 43 preferably positioner 40 is resilient enough and holes 40 are spaced from each other a distance such that center portion 78 of positioner 40 bowes or bends up springly in response to the inward force of the inward moving ring segments 44 46 the raised positioner keeps sheets which can include loose leaf paper and a sheet lifter from catching under lower portions 42 43 of the ring as it is clear from fig2 6 plate 56 is not hinged in a direction transverse to direction 62 inward from hole 64 to hole 66 in fig6 end 72 of sheet lifter 74 is cammed upward by folding up cover 80 end 76 of the sheet lifter is raised by plate 56 which was cammed upward by ring 50 when the ring was closed sheet lifter 74 raised by positioner 40 supports paper sheets 84 from being caught under the apex 88 of the elliptical curve segment 44 of binder ring 50 referring to fig7 9 positioners 90 are mounted on lower portions 96 98 of segments 104 106 of ring 110 for explanatory purpose only one sheet lifter lifter 108 is shown positioner 90 spaces sheet lifter 108 from ring.
