sheet lifter 10 is to be used having such properties the sheet lifter 10 is sufficiently rigid to support the notebook sheets 36 as they are being turned the operation of the sheet lifter 10 will now be described reference is made primarily to fig1 which depicts a plurality of sheets 36 held in the notebook 28 in a partially turned condition when the notebook 28 is opened with the sheets 36 lying flat on the right side of the notebook rings 30 32 and 34 the sheet lifter 10 will be positioned immediately over the sheets 36 with the inner edge 16 of the sheet lifter 10 corresponding to the inner edges 38 of the individual sheets 36 when the user begins to turn a group of sheets 36 to the position depicted in fig1 the sheet lifter 10 shifts laterally in a clockwise direction as shown in fig1 the oblong configuration of the holes 22 24 and 26 permits such lateral movement the clockwise shift in the sheet lifter 10 is caused by the action of the sheets 36 on the lower end 18b of the outer edge 18 which due to the angular configuration of the outer edge 18 will be contacted prior to the upper end 18a of the outer edge 18 the shifted condition is perhaps best shown in the sectional views of.
