Abstract

An automatic sorting machine for automatically sorting record receivers according to the elapsed time data printed thereon and for automatically punching the record receivers in accordance with printed time of day data appearing on the receivers. The machine includes apparatus for serially feeding record receivers to a scanning station having three scanning heads mounted to scan and convert printed data into radiant energy pulses that are analogues of the data. The pulses are sensed and converted to elapsed time and time of day BCD (Binary Coded Decimal) analogues. The elapsed time BCD analogues are applied as inputs to elapsed time error checking and correction logic which automatically corrects for error appearing in the printed data on the record receiver to generate elapsed time signals. The elapsed time signals are applied by electronics to selectively operate gate solenoids related to specific record receiver storage bins in the sorting machine. The time of day BCD analogues are applied as inputs to time of day error checking and correction logic which provides time of day signals corrected as stated above to selectively energize punch solenoids. The punch solenoids are energized by the signals while the record receivers are at the scanning station after which the record receivers are released to be automatically transported by the machine and stored in the bins selected by the elapsed time data. All logic is automatically restored in timed sequence with machines'' rate capability for storing documents.

The invention also relates to machines of the aforementioned type that have the additional capability for automatically punching a record receiver in accordance with data recorded on the receiver.

BACKGROUND OF THE INVENTION THE PROBLEM For many years telephone operating companies have used record receivers in card form for the purpose of providing records of the time of day that toll calls are commenced and records of the elapsed time for each such call. The record is usually made with a Calculagraph (registered trademark of the Calculagraph Company, Harrison, NJ.) by a telephone operator. Telephone company personnel thereafter visually read the printed data to determine the time of each call and its duration. The toll cards are thereafter marked to show total elapsed time of a call. The cards are then manually sorted into groups where a group differs from the preceding elapsed time group by a factor of l minute, e.g., all cards showing an elapsed time in the range 6 seconds through one minute seconds are collected as a first group; those cards showing elapsed time in a range of 1 minute 16 seconds to 2 minutes 15 seconds are collected in a second group, etc. Thereafter, a lead card, i.e., a card that is prepunched with a specific elapsed time, is made the first card in each group. For example, a card prepunched with an elapsedtime of one minute may be placed as the first card of the group of cards for the range 6 seconds 1 minute, 15 seconds, and a card prepunched for 2 minutes may be placed as the first card of the second group and so forth.

It should be noted that each card was provided with data at the placing of the call indicating the calling and called numbers and such other individual identification data as was appropriate.

The groups of sorted cards are thereafter used by automatic accounting machinery for at least the purpose of computing customers statements.

From the preceding discussion, it should be apparent that much saving in the way of labor and operating costs can be realized if thetoll cards are sorted automatically. Further savings can be realized ifthey are automatically perforated in accordance with the time of day.

PRIOR ART gate such that the gate is opened when the solenoid is energized.

Known prior art machines usually provide some form of reader and associated circuitry for detecting data carried by the document and for processing the data so as to selectively energize a gate solenoid. In the general case, magnetically coded data in binary form carried by the documents is read and inputted to a buffer storage. Logic is employed to respond to the storages outputs so as to energize a gate solenoid. Usually timing means are employed to relate machine sorting speed to circuit speed. An example of this art is represented by the teaching of U. S. Pat. No. 3,246,751. It has also been taught that character recognition apparatus may be employed to read numeric data appearing on documents, see U. S. Pat. No. 3,052,350. These machines are said to be employed to sort bank checks or mail.

In addition, it is known to associate a keyboard, operated punch to a sorting machine, see U. S. Pat. No. 2,745,493.

Finally, there is a suggestion in U. S. Pat. No. 3,03 l ,1 35 that a flying spot scanner and associated circuitry may be employed to retrieve elapsed time data from a telephone toll card and be used by a utilization circuit. It is therein stated that the utilization circuit may be a card punch device for punching an information card in the manner known in the art.

It is the principalobject of this invention to provide new and useful apparatus that automatically controls the operation of a sorting machine and punch in response to data represented by the angular relationship of marks on record receivers.
