Abstract

The present method provides the capabilities of automatic discrimination either of a passbook with round corners or other forms without a round corner. A feature of the discrimination method is aimed at the round corners of the passbook. Fig. 1 shows the physical logistics, and Fig. 2 shows a timing chart of both photo sensors according to the present method.

Method for Passbook Discrimination On the Banking Printer

       The present method provides the capabilities of automatic
discrimination either of a passbook with round corners or other forms
without a round corner.  A feature of the discrimination method is
aimed at the round corners of the passbook.  Fig. 1 shows the
physical logistics, and Fig. 2 shows a timing chart of both photo
sensors according to the present method.

      The discrimination is accomplished by sensing a difference of
the switching time of two photo sensors A and B.  The sensor A is
positioned to sense the leading edge of the passbook or other forms,
the sensor B is positioned to sense the reference edge of the
passbook or other forms, and the Sensor C is positioned to sense the
width of the passbook or other forms, as shown in Fig. 1.

      In Figs. 1 and 2, "t" represents a nominal time period from the
turn ON or OFF to the turn ON or OFF of both sensors A and
B at a nominal feed speed of the passbook or other forms; "t1"
represents a measured time period from the turn ON of the sensor B to
the turn ON of the sensor A; "t2" represents a measured time period
from the turn OFF of the sensor B to the turn OFF of the sensor
A; "T" represents a measured turn ON period of the sensor A; "WT"
represents a measured turn ON period of the sensor B; "Wt1"
represents a delay of the turn ON of the sensor B due to the round
corner of the passbook; and "Wt2" represents a delay of the turn OFF
of...
