Card

Read-Punch

INTRODUCTION

The IBM 1402

Card

Read-Punch

provides

the

1401

data

processing

system

with a punch

card

input

and

output.

The

read

feed

is

a

20

cycle-point

feed

equipped with a file feed which

has

a

capacity

of 3600

cards.

The

read

feed

can

process

cards

at

a

speed

of 800

cards

per

minute.

The punch

feed

is

a 16

cycle-point

feed which

can

punch

cards

at

250

cards

per

minute.

Five

radial

stackers

are

used

to

accom-

plish

stacking

of

the

cards

from

both

feeds.

The

read

feed

and

the punch feed

are

located

at

opposite

ends

of

the

machine

so

that

cards

are

fed

from

the

read

feed and

the

punchfeed

into

a

transport

assembly

above

the

stackers.

The

card

transport

system

is

driven

by

timing

belts

wherever

possible

to

reduce

machine

noise

and

maintenance.

Power

supplies

for

other

machines

of

the

system

are

located

in

the

1402.

FUNCTIONAL PRINCIPLES

The 1402

Card

Read-Punchcanreadcardsata

maxi-

mum

speed

of 800

cards

per

minute.

Actual

card

speed

is

governed

by

the

program

routing.

The

read

feed

is

equipped with a 3600

card

capacity

file

feed.

The

cards

are

fed

through

the

read

feed.

9 edge

face

down. The

card

path

is

illustrated

in

the

feed

schematic

diagram

(Figure

1-1).

As

the

card

passes

the

read

check

brushes.

80

columns

of

the

card

are

read

to

condition

the

hole

count

check

planes

in

the

1401.

It

is

then

moved

past

the

read

brushes

where

again

80

columns

of

the

card

are

read

and

entered

into

the

read

area

of

core

storage.

At

the

same

time

the

check

planes

are

conditioned

so

that

a hole

count

check

may

be

completed.

Next.

it

is

transported

past

the

stacker

selection

station

and

is

directed

to

the

appropriate

stacker

under

control

of

programming.

Three

stackers

are

available

to

re-

ceive

cards

from

the

read

feed. The NR

(normal

read)

stacker

is

used

unless

the

cards

are

program-

directed

to

stacker

1

or

stacker

2

(8/2).

The

1402

Card

Read-Punch

will

punch

cards

and

check

card

punching

at

a

maximum

speed

of250

cards

per

minute.

Cards

are

placed

in

the

1200

card

ca-

pacity

hopper.

Card

feeding

is

illustrated

in

the feed

schematic

diagram

(Figure

1-1).

As

the

card

passes

the

Punch

Feed

Read

(optional

feature).

80

columns

of the

card

are

read

into

the

read

areas

of

core

storage

of

the

1401

if

PFR

is

called

for.

Before

the

card

is

punched.

it

is

aligned

at

the

aligner

station

both

vertically

and

horizontally

to

insure

correct

punching

registration.

Punching

is

done by a

high-speed

punch unit. As

the

card

passes

the

punch

station.

circuits

are

set

up

in

the

1401 which allows

the

card

to

be punched

with

information

contained

in

the

punch

area

of

core

storage.

At

the

same

time

the

check

plane

cores

are

conditioned

so

that

a hole

count

check

may

be

per-

formed.

After

the

card

is

punched.

it

is

read

at

the

80

column

punch-check

brushes

to

condition

the

check

plane

cores

so

that

a hole

count

check

may

be

com-

pleted.

It

is

then

moved

past

the

stacker

selection

station

and

is

directed

to

the

appropriate

stacker

under

program

control.

Three

stackers

are

available

to

receive

cards

from

the

punchfeed. The

NP

(Normal

Punch)

stacker

is

used

unless

the

cards

are

program-

directed

to

stacker

4

or

stacker

8 (8/2). The

8/2

stacker

cannot

be

used

for

collating

between

the

punch

and

read

feeds.

The

card

transport

assembly

located

between

the

punch feed

and

the

read

feed

has

a

set

of

six

feed

rolls

along

with two

select

magnets

and

chute

blades

for

the

read

feed

as

well

as

two

select

magnets

and

chute

blades

for

the

punchfeed.

A

jam

bar

is

located

in

the

transport

assembly

to

provide

an

indication

of

a

jam

and

stops

the

machine

when a

card

jam

occurs

(Figure

1-2).

All

stackers

are

the

non-stop

unloading

radial

type

stackers

with a

capacity

of 1000

cards

each.

Cards

can

be

Principles

of

Operation

The

clutch

ratchet

is

continuously

running

and

makes

one-half

revolution

each

machine

cycle.

This

ratchet

is

engaged

by

a

drive

dog

and

detent,

which

are

controlled

by

the

action

of

the

drive

arm

and

inter-

mediate

arm.

The

dog

and

detent

are

spring-loaded

to

engage

the

ratchet.

They

pivot

on

studs

that

are

part

of

the

drive

arm

and

are

controlled

by

studs

that

are

part

of

the

intermediate

arm.

The

intermediate

arm

pivots

on a

sleeve

that

is

the

hub

of

the

drive

arm

(Figure

2-3).
