Definitions
- the present invention relates to record card reading apparatus of the type provided with a transport mechanism which advances the cards in a direction parallel to their length, from a feed hopper out of which the cards are guided one-by-one, through a throat, onto a track, under a reading station transverse to the track, and into an output stacker located at a lower level than the feed hopper.
- Another object of the invention is to provide a simple and less costly card reader, adapted to be more easily operated.
- the card reader is arranged with the output stacker located below the feed hopper, and so that the cards emerging 45 from the feed hopper arrive on the reading track by being transported along a feed track inclined to the horizontal.
- Each card leaving the feed hopper is transported first by a first driving apparatus and then by a second driving apparatus along the supply track and the reading track until the cardhas almost passed entirely by the reading station, and whereupon the card is arrested by a stop at the end of the reading track.
- the card is transported in the opposite direction under the reading station by a third driving apparatus, at which time the reading of the card occurs.
- the card is conducted by the first driving apparatus still in the opposite direction, along the reading track where it arrives at the output stacker.
- the card reader of the invention is characterized in that its size is considerably reduced. Because the output stacker is located below the supply hopper, the reader can also be operated very easily. Because of this, the reader of the invention is particularly appropriate for being used with a terminal set which is connected by a telephone or telegraph line to a central computer. The pulses delivered by the card reader, after possible conversion to a suitable code, can be transmitted to a telephone line; connected to such computer.
- FIG. 2 is an end view of the card reader of the invention
- FIG. 3 is a schematic block diagram of the electronic control circuits of the reader of FIG. 2;
- FIG. 4 represents waveforms of signals which occur in the circuits of FIG. 3.
- the terminal set shown in FIG. I is connected by a telephone or telegraph line to a central computer.
- card reader LC realized in accordance with the instant invention, is combined with a teletypewriter of a kind currently employed for terminals.
- the teletypewriter is provided with a tape punch PB, a tape reader LB, a console having a control keyboard CC, and a printer IM.
- keyboard CC it is possible, if necessary, to transmit information directly to the central computer.
- the transmission of the tapestored information is controlled by means of reader LB, which provides for reading of the tape, and printer IM, which provides for printing of the transmitted message in accordance with the signal pulses received thereby.
- the information is transmitted very rapidly to the central com- 40 puter with the aid of the punched tape.
- Card reader LC comprises a feed hopper l, in which are placed the cards to be read, an output stacker 2, or receiving hopper, in which accumulate the cards that are rejected after reading, and a series of conspicuous push buttons 3, serving to command and control the operation of the card reader.
- Card reader LC is preferably mounted on a support-cabinet 4, which contains the necessary control circuits, as well as the connection elements for connecting the reader to the exterior.
- Feed hopper l and output stacker 2 are superposed.
- Each side of the cards held in both of these hoppers is guided by a sidewall of the reader.
- the cards lie on an inclined base, not shown in FIG. 1, and are attracted by gravity toward an arresting wall.
- a card-weight 5 is normally positioned on the stack of cards in feed hopper 1, thereby facilitating the extraction of the cards from the stack.
- the fourth side of each hopper may remain entirely open, providing complete accessibility to the cards contained in the hoppers and easy operation by a person situated in front of the console.
- two drive rollers 6 can be brought into contact with the lower card of the stack in feed hopper 1 through openings provided in the base of this hopper, thereby providing for transporting the card through the usual throat toward the reading track.
- the continuously turning rollers 6 can be urged against the lower card in hopper l, by means of an electromagnet Ml.
- a card emerging from hopper 1 by means of rollers 6 is picked up by a first driving apparatus which comprises a friction drive wheel 7, continuously turning, and an opposed friction pressure wheel 8.
- a second friction pressure wheel 9 is located below drive wheel 7 and is adapted to be urged against drive wheel 7 by the action of an electromagnet M4, the purpose of which will be described hereinafter.
- the card is transported by the first driving apparatus along a slanting feed track 10 toward the reading track 11, along which the reading station is denoted by the reference numeral 12.
- a stop 13 is disposed at the end of reading track 11. The distance from reading station E2 to stop 13 is slightly less than the length of a card. Between reading station 12 and stop 13 there is located a second driving apparatus. which comprises a friction drive wheel 14, continuously turning, and a friction pressure wheel 15, which is urged against drive wheel 14 by means of an electromagnet M2.
- a common motor 18 drives rollers 6 and wheels 7 and 14 in the same direction and at the same circumferential velocity by means of belts l9 and 20.
- a third driving apparatus is located immediately adjacent to reading station 12.
- This third driving apparatus comprises a friction drive wheel 16, adapted to be driven by a stepping motor 21, and a related friction pressure wheel 17, adapted to be urged against drive wheel 16 by means of an electromagnet M3.
- Wheels 16 and 17 act on a longitudinal edge of the card.
- the direction of driving of wheel 16 is such that, after energization of electromagnet M3 and the arrival of appropriate pulses at stepping motor 21, the card is transported in a direction opposite to its prior motion.
- a detection station B located immediately in front of stop 13, generates a signal at the time of passage of the leading edge of a card, whereby electromagnet M2 is de-energized.
- electromagnet M2 is de-energized.
- pressure wheel is not entirely disengaged from drive wheel 14 but continuous to rest against wheel 14 with a slight resilient pressure, so that the card continues to be urged against stop 13 with a small force.
- electromagnet M3 is energized, whereupon the card is conducted step-by-step through reading station 12 in a direction opposite to its prior motion. During this step-by-step displacement, the card is read columnby-column. The card then passes under feed track 10 and is pushed between wheels 7 and 9. Following the complete reading of the card, its trailing edge passes reading station 12, which provides for the appearance of a signal that ends the energization of electromagnet M3 and initiates the energization of electromagnet M4. The card, now held between wheels 7 and 9, is conducted toward output stacker 2 at a high velocity.
- aforementioned signal corresponding to the trailing edge of the card also initiates at the same time the transport of a new card from feed hopper 1 toward feed track 10. During this transport, the new card slides partially along the card being ejected.
- a detection station A is provided immediately adjacent to the throat of feed hopper 1. Detection station A generates a signal which falls at the time of the passage of the leading edge of the card. If this signal occurs after a predetermined time delay, the card feeding is automatically interrupted by the control circuits.
- Detection station B is located preferably a distance of a few millimeters from stop 13. Since the energization of electromagnet M2 ceases before a card reaches a stop 13, deterioration of the front edge of the card is prevented. When electromagnet M2 is de-energized, the card is driven in a slipping manner, so that it will only be pushed lightly against stop 13.
- the control circuits will now be described with reference to FIG. 3.
- the transfer of information to the central computer takes place by means of a rotating electromechanical distributor RV.
- a rotating armature of distributor RV makes electrical connection in succession with ten contacts during each revolution.
- the ten contacts comprise a start segment SD, eight contacts of which each is coupled to output line TL through the moving contact of a respective one of coding relays CR, and a stop segment SA.
- the armature of distributor RV rotates continuously during the operation of the reader.
- distributor RV may be formed by the distributor already present in the teletypewriter.
- the moving contact of a validity relay VR is provided in output line TL, so that a signal transmission may only take place if relay VR is energized.
- the control circuits receive supply voltage through a principal circuit breaker HS.
- a rectifier GR commences operation.
- Rectifier GR furnishes the direct voltage necessary for supplying the control circuits, and a pilot lamp Ll lights at the same time.
- the reader may be controlled manually by means of three buttons; namely, a start button Tl, a stop button T2, and an ejection button T3.
- a start button Tl By depressing button Tl, the reader is started, whereas its operation is interrupted by depressing button T2.
- Depressing button T3 initiates the ejection of the card present under reading station 12.
- the starting of the reader may also be initiated by a signal S1 and the stopping also by a signal S2, each of those two signals being provided by the central computer.
- this control may be effected by means of a combination of punch'codes in a card.
- the punch code Ejection UC may be entered in the column following the last column to be read, wherein the punch code Ejection UC initiates ejection of the card.
- the punch code Stop SC may be entered in the following column, which punch code initiates the stopping of the reader.
- decoder-encoder CV is provided with eight output terminals for transmitting information, each of these eight output terminals being connected to a respective one of coding relays CR.
- Decoder-encoder CV is also provided with three output terminals for controlling the operation of the reader; namely, an output terminal UC, on which a signal appears when the punch code Ejection is read, an output terminal GK, on which a signal appears when all of the photo-electric cells of the reading station are illuminated as when there is no card under reading station 12, and an output terminal SC, on which a signal ap pears when the punch code Stop is read.
- flip-flop FF When the reader is started by the depression of button T1, or by the arrival of a signal S1, at flip-flop FF is set through an OR-gate 01.
- the setting of flip-flop FFl causes the setting, in turn, of a flip-flop FF2, whereby principal motor 18 begins to turn.
- a pilot lamp L2 lights and rotating distributor RV is coupled to the voltage source GR.
- a flip-flop F F3 is set through an AND-gate E2 enabled by signal GK, which signal is present because there is not yet a card under reading station 12.
- the setting of flip-flop FF3 initiates the energization of electromagnets M1, M2 and M4.
- the energization of electromagnet M1 is provided by a monostable multivibrator (one-shot) TUl, which generates a pulse of approximately l00ms duration. At the termination of this pulse, a differentiator D1 generates a signal which controls the card located at that time in the vicinity of detection station A.
- a monostable multivibrator (one-shot) TUl which generates a pulse of approximately l00ms duration.
- a differentiator D1 generates a signal which controls the card located at that time in the vicinity of detection station A.
- rollers 6 are urged against the lower card of the stack in feed hopper 1, whereby such lower card is transported toward reading track 1 1.
- this card Prior to the end of the period of energization of electromagnet Ml, this card is picked up by the first driving apparatus, comprising wheels 7 and 8, and is conducted past reading station 12.
- the card After passing reading station 12 the card is picked up by the second driving apparatus, comprising wheels 14 and 15, and is conducted towards stop 13.
- the second driving apparatus comprising wheels 14 and 15, and is conducted towards stop 13.
- flip-flop FF3 When the leading edge of the card reaches detection station B, flip-flop FF3 is reset and terminates the energization of electromagnets M2 and M4.
- a flip-flop FF4 is set and initiates the energi zation of electromagnet M3. The reading of the card now commences.
- F lip-flop F134 furnishes a signal to a first input terminal of an AND-gate E3.
- a differentiator D2 delivers a signal to the second input terminal of AND-gate E3, which thereupon delivers a signal to set a flip-flop FF5.
- the output signal of flip-flop FFS energizes validity relay VR and is-also applied to a first input terminal of an AND-gate E4 through a delay element R.
- Output line TL is now coupled to distributor RV by the moving contact of relay VR, so that during the passage of the armature over the eight intermediate contacts signals are delivered to line TL in correspondence with the particular energized coding relays CR.
- a difierentiator D3 delivers a signal to the second input terminal of AND-gate E4.
- delay element R is delivering an output signal.
- AND-gate E4 emits a pulse to stepping motor 21 through an OR-gate 05, thereby initiating the displacement of the card being read by one column.
- flip-flop FFS is reset as the signal from differentiator D3 passes through an OR-gate O4, whereupon relay VR is deenergized.
- flip-flop FFS is once again set, to enable the transmission of information from the next column of the card.
- the columns of a card are read one after the other and the information read is transmitted to the central computer.
- the signal GK issues again, initiating the setting of flip-flop FF3 through AND-gate E2.
- the setting of flip-flop FF3 again initiates the energization of electromagnets M1, M2 and M4.
- the signal GK also resets flip-flop FF4, terminating the energization of electromagnet M3.
- the operation of the reader is interrupted if button T2 is depressed, if a half signal S2 is received or if the punch code Stop SC is read.
- flip-flop FFl is reset by passage of a respective signal through OR-gate O2, whereupon the voltage supplied to distributor RV is removed.
- a pulse is simultaneously delivered to stepping motor 21 through OR-gate 05.
- the card read is displaced to the next column and terminates the reading of the punch code Stop, which is necessary to permit the reader to start once again.
- the operation of the reader must also be interrupted when, at the end of the energization period of electromagnet Ml there is no card present at detection station A. This signifies that feed hopper l is empty or that there is a throat jam. So long as there is no card at detection station A, a signal is supplied to one of the input terminals of AND-gate E1. The output signal of differentiator D1 is applied to the other input terminal of AND-gate E1. When the two input signals to AND-gate E1 arrive at the same time, a flip-flop FF 1 is reset through OR-gate 02. At the same time flip-flop F F2 is reset following some delay through the intermediary of .a one-shot TU2 and a differentiator D4, whereupon principal motor 18 is halted and pilot lamp L3 lights.
- Pulse generator G provides pulses at a recurrence frequency of Hz, which pulses are applied to stepping motor 21.
- the card located under reading station 12 is thereupon displaced by stepping motor 21 at high velocity; i.e., at 150 steps per second, which may be contrasted with the reading velocity of a card of only 10 steps per second, during which each step is taken in synchronism with a revolution of distributor RV.
- the card rapidly leaves reading station 12.
- the signal GK issues and resets flip-flop FF6, thereby removing the control voltage applied to generator G.
- energization of electromagnet M3 is interrupted and electromagnets M1, M2 and M4 are energized.
- the card is then ejected by wheels 7 and 9, while the next card is fed by rollers 6 and wheels 7 and 8.
- Waveforms appearing during the operation of the reader of FIGS. 13 are shown in FIG. 4.
- Waveforms M1, M2, M3 and M4 represent the intervals during which correspondingly identified electromagnets are energized.
- Wavefonns A and B represent the output signals delivered by respective detection stations A and B.
- Waveform Dl represents the output signal of differentiator D1, which signals during normal operation, must not coincide with the output signal delivered by detection station A.
- Waveform GK represents the signal GK delivered by decoder-encoder CV.
- Waveform SA represents the pulses delivered by stop segment SA of distributor RV.
- Waveform VR represents the intervals during which relay VR is energized.
- Waveform SM represents the pulses furnished to stepping motor 21.
- this card cycle may be reduced considerably by the utilization of the aforementioned punch code for ejection.
- the same effect may be obtained by utilizing, for example, commutators which rotate under manual control and have 80 positions providing for the selection of zones desired to be read. In such instance, the card is displaced at high velocity in the zones located before, after, and between the selected zones.
- the reading velocity may be increased within certain limits if the rotating distributor is replaced by an electronic pulse generator.
- the high velocity of the card (150 columns per second) which is present during the period when stepping motor 21 is driven by pulse generator G, corresponds, preferably, to the velocity of the card during its transport from feed hopper 1 to stop 13 and during its ejection by wheels 7 and 9.
