Cause
Wrong

Cause
A
square
component
was
recognized
by
the
comer
detection
function
but
no
recognition
error
occurred
and
the
component
was
placed
because
X

Y
were
equilateral
although
it
was
on
the
skew

These
two
electrical
contacts
were
recognized
as
leads

.
Remedy
The
component
was
recognized
as
a
leaded
one
，
so
that
a
recognition

occurred
when
the
