(57) The invention relates to a full automatic document selection and sealing device comprising
a collating unit (A) which includes plural shelves (3) to carry document paper sheets
of different types thereon, rollers (4) separately and individually controlled by
a computer to select and feed the paper sheets one by one from the shelves, and optical
sensors (15) located between adjacent shelves to detect paper sheets thus fed, the
optical sensors being connected to feeding rollers (11,12) that are separately and
individually driven; a folding unit (B) serially connected to the collating unit (A)
which includes plural sets of folding rollers (21), and a control means to define
folding positions on the paper sheet, and which folds the paper sheet either into
two or three folds; an enclosing unit (C) which includes a supplying unit provided
near the discharging terminal of the folding unit (B), a conveyer belt (29) laterally
to be driven by a pulse motor, the conveyer belt carrying thereon rollers that are
driven by a motor and which pay out envelopes one by one at one end of the belt, a
folding roller to apply a folding line on the tongue of the envelope at the other
end, and an opening means for opening the mouth of an envelope at an intermediate
position on the belt; and a sealing unit which includes a pasting means, a folding
vane and a press means whereby the device can continuously collate, fold, enclose
and seal the document paper sheets.
