Description
SUMMARY OF THE INVENTION
This invention relates to means, ways and methods for
electronically checking and certifying certain requested
information and requests to a central station which are received
from one or more primary stations or card receiving or card
switching units which may be termed a card switching unit, or
units. It is really a pick-up unit which is adapted to receive
special electrical switching cards which are portable and can be
carried upon a person in a pocket or in a purse. Such a card may
request certain information that has been previously computerized
at a central station and upon demand of such information, it is
immediately, and directly sent from the central station to the
primary station or switching unit.
In a credit investigation, such information may state a card
holder's identification by number such as his Social Security
number, his account number, his bank balance, his driver's number
and much other information or may merely state a yes or no as to
whether or not the card holder is a good risk for the amount of
money involved.
All that the attendant at the primary station or pick-up unit
(retail store or gas station) need do is to insert the
computer-like card of a customer into a pick-up unit or switching
box. The card has a plurality of electrical conducting spots
thereon which closes certain electrical circuits within the pick-up
box and from which special electrical bits are flashed to a central
station where certain matters are checked and certified; and then
the desired information is automatically flashed back to the
primary station.
One of the principal objects of this invention is to present
automatic electrical means and methods to receive certain
information from a central station regarding certain needed
facts.
Another object of the invention is to provide a quick reliable
system and method to confirm or not confirm the credit standing or
other facts regarding the card holder through automatic electrical
means.
Another object is to economically check various matters concerning
a card holder at a primary station which may be a retail store or
other business house and which matter may include an identification
of the card holder and that he is entitled to the privileges
represented by the card and also whether or not the card holder has
a good standing credit.
Still another object is to provide a foolproof system to check on a
card holder who is involved in a special event which may be a
business transaction, admittance to a club, a traffic violation,
obtaining transportation, certifying prisoners and detectives, and
many other matters.
Still a further object is to provide for a great plurality of card
holders whose maximum number is equal to 2.sup.n -1 where n is the
number of switch means to cause card interfacing of the circuit
plate means.
Other objects and aims of this invention will became apparent upon
inspection of the drawings and perusal of the specification and the
claims.

DETAILED DESCRIPTION OF THE DRAWINGS
The drawings illustrate one way in which the invention can be
practiced.
In the portion of the drawings marked "Store" in FIG. 1, there is
shown the front view of the cash register 1 which is of the common
variety and may be of the kind marketed by the National Cash
Register Company. Such a register generally has an outer casing
indicated at 3 which encloses the mechanism.. The front panel is
generally curved or slanted and has a plurality of openings which
accommodate the plurality of push buttons etc. indicated by the
reference character 6. A chamber with a glass front has a plurality
of lined wheels 4, and each wheel has about its outer curved rim a
plurality of digits ranging from zero to nine to indicate the money
total of sales. The cash register 2 is shown in side view with a
portion broken away.
Along one side of the register 1 or 2 (obviously there may be a
large number of such registers in a large retail store or other
stores) there is a receipt protruder means having the casing 7 with
its well known slot 8. A push bar 9 is also a common part of such
registers, and this bar starts the operation of a totalling machine
within the casing and protrudes the receipt through the slot 8. The
registers are shown with the usual handle 11 upon a drawer 10.
Along the other side of each register there is provided, as part of
this invention, an interface unit or switching unit 12 having means
which accommodates a portable card or the like in a well at the top
of the unit and which will be explained later.
FIG. 1 shows a conduit means 14 which protects certain cable means
that make connection with the unit 15. This unit 15 is a Codex unit
TM 8/TM 15 Mux Demux device, and it has electrical connection with
16 which is a Codex AE 96 a Modem. From the Modem a cable means
makes connection with a telephone line 18 which leads to 19 a Codex
AE 96 which is also a Modem.
The Codex unit 19 makes cable connection with 20 which is an IBM
unit 2701 Data Adapter through line 21. Line 22 connects 20 with 23
which is an IBM 360/40H. This unit has connection with a card unit
24 through line 25. From unit 23 via line 26 connection is made
with a tape dispenser 27, and another line 28 leads to a disc unit
29.
The cash register 1 has a windowed section 40 behind which is a
series of wheels or circular band means 41, 42, 43, 44 and 45
(FIGS. 3 and 4) which are independently rotatable on an axle 46 by
mechanism within that is well known in the art. These wheels are
rotated by pressing various numbered keys 6 so as to ring-up the
amount of a sale or sales. The sales tape is printed within the
casing 3 or 7 in a well known manner and then is shifted through
the slot 8. Each wheel has the spaced digits 0 to 9, and they are
mounted and individually rotated by their respective rubber rimmed
small wheels like the one indicated at 42. It is believed
unnecessary to give details as to how the common cash register
works in that to do so would burden the application
unnecessarily.
Immediately below the various numbers on each wheel (41-45') are
shown four spaced apart spots 44', and the ones marked with an X
are the ones that conduct electricity. Nonconductor spots are shown
but can be omitted, however, the spots so marked are conductor
spots which contain a good conductor of electricity which may be
carbon or some metallic material. Each number is identified by the
position of the conductor spots, therefore, the arrangement of the
spots indicate the number. For instance, note the nine which is
represented by the end spots which are conductors, and the number 7
is represented by one non-conductor spot and three conductor
spots.
A cross bar member 45 (FIGS. 4 and 5) has its ends supported by
side walls of the cash register, and spaced along the bar are
series of matched pairs of contacts or pegs which have casings
indicated by the numeral 46'. Each casing 46 is a tube of
insulating material having a bottom 47, and the open end is firmly
attached to the bar 45 which is also of insulating material. The
connection may be by a suitable cement. Opposite sides of the tube
have the slots 48, and 49 and shiftable within the tube is a pair
of spaced apart electrical metal contacts or peg members 50 and 51.
These conductor pegs are spaced apart by an insulating strip 52.
The pegs and insulating strip are neatly rounded at their outer
ends so that the switch or paired combination can easily slide on
and off its respective conductor spot 44' as the wheels 41-45' are
rotated by operation of the cash register to display the amount of
sale.
To make sure of good contact between the pegs and their respective
conductor spots, the spring means 53 is provided, and the forward
loop of this spring is covered by a suitable non-conductor of
electricity, or the bottoms of the pegs are insulated so as not to
cause closing of this type of switching device by the spring. The
slot 48 accommodates a conductor wire 97 which has one end
connected to peg 50 and the other end connected to square wave
pulse generator 95' shown in FIG. 2. The slot 49 accommodates the
insulated conductor wire 55 which has one end connected to the
accummulator 85' (FIG. 2) and the other end connected to peg 51.
All the live conductor wires are accommodated by a trough-like
means 56. The switching means along the bar can make electrical
contact with their respective conductor spots on the wheels and all
these conductor wires 55 carry their respective electrical bits to
feed the accumulator 85'.
As shown in FIG. 2, a cable leads from accumulator 85' to a relay
switch 88 having the magnetic coil means 89 for its control. Via
cable means 60' the switch 58 is connected to the shift register
61.
At this point of the specification, we must consider the switch
plates 62, 63 and 64. These plates need be but a single plate as
shown in FIGS. 11 and 12 at 65; but the sections 62, 63 and 64 each
have a special purpose to be explained presently. The section 62,
for instance, is the array card or credit card section; the section
63 is for a very special use for generation of the device address
etc.; and section 64 is the primary station identification section
which may be for the store or gas station, for instance.
Each section receives a special card and the cards are indicated by
the reference characters 66, 67 and 68. The plate 65 is the top
wall of a cabinet having four sides 69, 70, 71 and 72 (FIG. 10) and
a bottom wall 73 to provide a chamber 74 which accommodates
equipment for the unit. Cross members 75 and 76 provide three wells
or recesses which neatly accommodate the various cards 66-68, and
these recesses are sized just a little larger than their respective
cards so that the cards can be kept directly in place onto the
particular section of the plate 65. The cards 67 and 68 may be
fixed in position if desired, but the portable card 66 is a
personal card and is carried only by a particular person or perhaps
a particular agent of a business firm. The unites 77 are heavy
blocks of metal or plastic for holding down their respective cards
firmly against the proper section of the plate for good electrical
contact between the conductor spots on the cards and their
respective switching pegs on the plate 65. If the weight units 77
are of a conductor material, then insulating sheets are placed upon
them, that is, their top and bottom surfaces, as indicated at 78
and 79.
Machine pressed into each switch plate area or section 62-64 are
the paired conductor pegs or contact metal elements 80 which
substantially cover their particular section. As shown in the
enlarged views of FIG. 8 and 9, the paired pegs 81 and 82 are
spaced apart in the plate which is of a suitable insulating
material which may be plastic. Certain pegs lead to a common cable
means via wires 97 and one peg of each pair has its individual
insulated wire such as 84, and these wires lead to the unit 57
which is an accummulator (see FIG. 2). Similar cable or wires 86
lead from another switch plate section 63 to 57 and the same is
true regarding another switch plate section 64, that is, its cables
or wires lead to the unit 57, the cables being indicated by 87. For
purposes of clarity, only portions of the switch plate section are
shown in FIG. 2. From the unit 57 cable means lead to and through
the switch relay 58 which has its control coil 59, and said cable
means reach the shift register 61. From register 61 leads a cable
means 103 to a delay timer 102 which slows transmission, and this
is for the purpose of making sure of proper timing. From the unit
102 the electrical message bits are fed into the Codex unit 15
through line 104 and a transmitting polar relay 130 and then to the
bank via telephone line or other means as line 18. The coil 93' in
FIG. 2 is a delay reactance means which delays the operation of the
entire system.
As shown in FIG. 2, the push bar 9 of the cash register
mechanically works a lever on the switch 91 to connect electrical
current from line 92 to the line 93, and this line 93 energizes the
coil 94 on the relay switch means 95 which controls DC current from
96 to feed line 97 in each switch plate section 62, 63, 64 and 45.
Numeral 95' indicates a square wave pulse generator. The branches
from this line 97 feed the live sides of the paired switch pegs,
and when these pegs are bridged by various conductor spots on the
cards 66, 67 and 68 (as well as the spots on the wheels
41-45)electrical bits are generated and sent to unit 57 or 85' as
the case may be. The cards have conductor sports 100 which were
selected for a special purpose to be explained; the spots close
circuits to send message bits. Thus certain circuits are closed
while others are left open.
A photo sensitive cell 98 has the connecting lines 99 and 99' The
answer tO the electrical bits from the switch plates is made at the
bank where electrical bits from a computer means come through
various units, that is, Codex 15 and thence to the shift register
106 (FIG. 2) via cable line means 107. From the register 106 the
electrical bits are directed through the various AND gates 108,
109, 110 and 111 and the cross line which has the NOT gate 112 and
thence via cable lines 113 and 114 to a particular part of the cash
register 1 or 2, for instance, to cause operation of a printer
device as shown in FIGS. 13-15.
Now, with reference to FIGS. 13 and 14 electrical bits passed
through line 113 will energize the coil means 115 of of the relay
switch 116 and thus allow a heavier current to flow from a battery
(or current converter) 117 into line 118. If the electrical bits
pass through line 114, the coil 119 is energized, and this would
close the relay switch 120 and provide heavier current to line 121.
Each line includes its respective resistance-capacitance unit 122
or 123, and these lines feed their respective magnetic coil means
124 or 125.
Mounted upon a suitable base 126 are the magnetic coils 124 and 125
and also the spring arms 127 and 128 and the housing 129 wherein is
accommodated a coil of paper tape or the like that is common in
cash registers. This tape is realy a pair of tapes 130, and 131 and
they are coiled together and stored ready for use in the housing
129. A slot 132 in the housing allows the tapes to be fed along a
platform 133 to a tear-off edge 134. A space A is shown along the
tape to show where the well known printer in the common cash
register can be placed for stamping the prices of sale items and
totalling same. Further details of such a common printer is
believed unnecessary in that it is not per se a part of this
invention. The top tape 131 is a carbon strip and the bottom one
130 is an ordinary paper strip as now employed by cash registers.
Obviously, the carbon strip need not be coiled with the sales slip
or strip in the housing 129 in that there may be any suitable means
for inking the stamper of this invention.
The flexible springy arms 127 and 128 each have a base portion 135
which is secured to the support means 126. The distal end of each
arm has a stamp means as shown at 136 and 137; under the stamp in
each case is a print die wherein one may have a NO and the other a
YES. Each arm has a magnetic disc 138 which is pulled downwardly
when the magnetic coil beneath it is energized; and when this
happens, the stamp of that particular arm will snap onto the top of
tape 131 and thus print its mark upon the tape 130. Obviously many
more magnetic coils and stamps and circuits may be employed along
with various letters or numbers so as to write a message etc., but
it is believed sufficient to describe only a simple stamping means
to avoid burdening this case with additional drawings and
specification.
The devices used in the description may be similar to the type
suggested below. All other devices are either explained in detail
or are well known and obvious in function.

OPERATION
The operation of the system begins when both cards 66 and 68 are
laid upon the swtich plates 62 and 64 and the weight units 77 are
dropped into place. This action cuts the light beam between the
sending unit 98' mounted beneath the switch plate 62 and 64. The
photo sensitive cell 98 is securely mounted within the weight units
77 and this acts as an "Electric Eye" device.
When the light beam is cut the current on line 99 to switch 91
causes the swtich 91 to close and thus permits a current from the
power source 92 to flow over line 93 providing push bar 9 is
depressed. The light beam will be received by the photo sensitive
cell 98 at anytime the cards 66, 68 are not in place and thus
keeping switch 91 open. When switch 91 is open under this
configeration no current will be permitted between the power source
92 and the line 93 regardless of the position of the cash register
push bar 9. This arrangement isolates the system from the cash
register and thus permits independent cash sale operations in the
well known manner.
Assuming the cards 66 and 68 are properly in place, depression of
the push bar 9 will cause a current over line 93 which activates
the system. Current will also go to delay line 93' and its action
will be explained later. This permits a burst or surge of DC
current from the solid state regulated power supply A of 4 volt
current (see FIG. 2) which is supplied through switch 95 to line
97". Line 97" provides the current to the square wave pulse
generator 95'. This pulse continues over line 97 to the switches on
the switch plates as; 62, 63 and 64, and cross bar 45.
The circuit through the switches will either be completed or
inhibited depending on the overlay of the code card. If the code
card overlay has a conductor spot, the square wave pulse will be
x-mitted over lines 84, 86 and 87 to the accumulator 57 as
electrical bits where they will be temporarily stored. If the code
card overlays a nonconductor spot on the switch plate, no pulse
will be transmitted to the accumulator.
The line 97 simultaneously transmits the square wave pulse to the
switches located on the cross bar 45 anchored inside the cash
regaister. The conductor spots 44' insure the correct decimal
digits from the wheels 41-45' are converted to binary as the square
wave pulse passes through pegs 50 and 51 in exactly the same manner
as described for the switch plates. The pulse representing binary
digits is transmitted to the accummulator 85' where it is
temporarily stored.
At this time, it is best to digress to switch 91 which feeds line
93 when the push bar 9 is depressed to begin the operation. The
current in line 93 is fed to to delay 93' and transmitted to the
magnetic coils 59 and 89 which control the relay switches 58 and
88. After being suitably delayed, the current activates the
switches 58 and 88 which causes the accummulators 85 and 57 to dump
their contents to the shift register 61. The contents will contain
at least the following information; price of sale (cross bar 45),
customer and account identification (card 66), shop & account
identification (card 68) and device address (card 67).
The shift register may have connected by line 101 an external clock
100 (consisting of an oscillator) which synchronizes the shifting
of the register contents. The contents (electrical bits) are dumped
serially to line 103 which transmits to the monostable
multivibrator 102 used as a delay timer and pulse absence detector
which slows the transmission rate to the required 75 BPS for line
14. The bits are then transmitted to the transmitting. polar relay
where they are converted to .+-. 130 volt polar at 20 miliamps
which is required for line 14.
The TM15 mux/demux 15, modified to return a receipt of message now
called ROM, and will transmit the ROM if the data is correctly
received. The ROM will be received through the receive polar relay
140 and transmitted over line 107 to the interval timer 90 which
may also be a monostable multivibrator. If this ROM is not received
at the interval timer 90 within an imperical time interval, the
interval timer will trigger synchronization over the line 107'
causing reset of the shift register 61. This action causes the
contents of the shift register to be retransmitted.
Line 14 is a full duplex line which is used to return a message
from the central processing unit. The CPU will save the device
address and attach it to a return message which indicates whether
the transaction was successfully completed. This message will be
received at the receiving polar relay 140 and will be transmitted
over line 107 to the shift register 106. The oscillator clock 100
synchronizes the shift register 106 which dumps the return message,
consisting of a device address and/or message indicating
disposition of the transaction, to the coincidence gates 108, 109,
110, 111 and 112. These coincidence gates may consist of AND gates
108-111 and a NOT gate 112. The correct address received at gate
108 will trigger a "1" output to AND gates 110 and 111. Depending
upon the success of the transaction, the transaction message,
received at gate 109 will trigger a 1 output at gate 110 or 111(not
both) because of the NOT gate 112.
A positive response will be transmitted over line 113 or 114, as
shown in FIGS. 13-15. The positive response will trigger gate 116
or 120 causing DC power from source 117 to be transmitted over line
118 or 121 to a capacitor 122 or 123. The capacitor will drain
during a predetermined time interval through its associated
transistor. This current energizes electromagnet 125/139 or 124/138
which causes the stamp 137 or 136 to strike the ribbon or tape
means 131. One stamp may have the type NO and the other one the
type YES meaning that the transaction was successfully completed or
it was not. It is only a matter of a few seconds to receive an
answer.
Certain novel features and details of this invention are disclosed
herein, and in some cases in considerable detail, and this is in
order to make the invention clear in at least one form thereof.
However, it is to be clearly understood that the invention as
disclosed is not necessarily limited to the exact form and details
disclosed since it is apparent that various modifications and
changes may be made without departing from the spirit and scope of
the invention as described and claimed.
