Optical Mark-Sensing Passbook Line/Page Find Device (OLF/OPF)

      An optical mark-sensing device reads identifying marks in a
dedicated column of a bank passbook, or other multi-printed
multi-page document, to ascertain that the correct page and column
are positioned for printing.

      The Figure shows this device schematically.  In this
embodiment, the extreme left hand column of passbook 1 is reserved
for two groups of rectangular black marks.  The blocks in the upper
group 3 are preprinted binary encoded page numbers (four blocks for
16 pages, five blocks for 32 pages, etc.).  The blocks in the lower
group 4, identify lines which have been printed in previous
transactions. They are printed by the passbook printer as the first
character of the line being printed.  The marks are detected by known
simple mark-sensing technology consisting of a light source 5 and a
photo detector 6 requiring no lens.

      It is readily seen that, as the passbook enters the printer,
the page number blocks are read first and verified as the correct
page to be printed.  The passbook then advances, over printed line
blocks, until a blank space is sensed.  This identifies the line to
be printed.
