FUNCTIONS
POCKET/STANDBY
indicator
The
POCKET
indicator
glows
red
when
a
(red/yellow)
rejected
card
is
put
in
the
normal
stacker
or
when
a
valid
card
is
fed
to
the
reject
pocket.
The
indicator
is
turned
off
by
pressing
OPERATE/RESET.
STANDBY
glows
yellow
when
the
subsystem
is
in
the
standby
mode.
The
indicator
goes
off
when
the
subsystem
returns
to
the
normal
mode
of
operation.
Card Ha’ndling Mechanism
The
card
handling
mechanism
consists
of
an
input
hopper
capable
of
holding
1200
cards,
an
output
stacker
with
a
capacity
of
1200
cards,
a
reject
pocket
with
a
capacity
of
at
least
100
cards,
and
a
card
track
for
moving
the
cards.
The
card
track
moves
cards
forward,
row
by
row,
in
response
to
feed
signals
issued
by
the
punch
controller.
A
set
of
80
punch
dies,
regulated
by
the
control
electronics,
punches
cards
a
row
at
a
time.
The
postpunch
read
station
of
80
wire
brushes
checks
the
accuracy
of
the
punching.
Warning
switches
in
the
mechanism
halt
the
punch
whenever
an
improper
condition
exists.
A
weight
in
the
input
hopper
holds
cards
so
that
the
bottom
card
rests
firmly
against
the
feed
plate.
A
convenient
place
for
manually
aligning
card
edges
is
provided
by
a
jogger
plate
located
near
the
loading
and
unloading
areas
of
the
punch.
Card
chips
created
by
the
punching
operation
are
accumulated
in
a
large
removable
chad
box.
Before
punching
begins,
the
card
punch
must
be
properly
loaded
and
free
of
any
Attention
conditions.
The
subsystem
becomes
busy
and
card
punching
begins
when
a
punch
instruction
is
received
and
accepted.
As
soon
as
the
punch
becomes
busy,
it
requests
data
for
the
card.
Data
is
transmitted,
character
by
character,
from
the
processing
system
to
the
card
image
buffer
of
the
punch’s
controller.
The
parity
of
each
character
is
checked
as
it
is
received.
If
the
instruction
requests
the
data
to
be
punched
in
the
Hollerith
code,
the
code
is
converted
by
the
con-
troller
before
the
data
enters
the
buffer.
If all the data for the punching of a single card (160 binary characters or 80 alphanumeric
characters) is received by the feed time following initiation of the punch instruction, the
first card moves from station 3 into the punching area, face down and row 9 first. All
cards in the track begin moving forward to the next station. ( See Figure 23.)
