Abstract

Abstract This invention provides a means for determining if the individual punched cards in a deck of punched cards are in proper sequence, if the deck is complete, and if the deck contains strange and unrelated cards. Once a deck of cards has been arranged in its proper sequence, the edge of the deck is painted with a stripe of magnetic material, and information representing the order of the cards in the deck is recorded thereon. At a subsequent time, and before the deck is read into a computer, the magnetic information on the edge of the deck is read to check the order and completeness of the deck of cards. Information may be recorded on the magnetic stripe in the form of pulse patterns, or in the form of positional information. The recorder is a simple device using a standard multichannel magnetic pulse recording head and provides the means for moving the deck of cards past the head. The reading device is similar to the recording device.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 104 words
Apparatus for indicating that a group of record receivers is complete and in a proper prescribed order, said apparatus comprising a plurality of record receivers having information recorded thereon, said plurality being arranged in a prescribed order to form a single file, first means applied along one exposed edge of said file for receiving information indicating the order in which the individual record receivers are arranged in said file, second means for reading the information recorded on said first means, and third means responsive to the information read from said first means for indicating when said record receivers are not in the prescribed order.
Claim 2
Dependent Claim 104 words
Apparatus for indicating that a group of record receivers is complete and in a proper prescribed order, said apparatus comprising a plurality of record receivers having information recorded thereon, said plurality being arranged in a prescribed order to form a single file, first means applied along one exposed edge of said file for receiving information indicating the order in which the individual record receivers are arranged in said file, second means for reading the information recorded on said first means, and third means responsive to the information read from said first means for indicating when said record receivers are not in the prescribed order.
Claim 3
Dependent Claim 82 words
The apparatus defined in claim 1 wherein said second means comprises a standard source of sequential information which corresponds to the arrangement of the information recorded on said first means, fourth means for reading said standard source, comparison means, fifth means for applying the output from said second means to an input to said comparison means, and sixth means for applying the output from said fourth means to said comparison means so that said comparison means compares said two inputs for correspondence.
Claim 4
Dependent Claim 46 words
The apparatus defined in claim 2 wherein said information recorded on said first means comprises a numerical sequence, and wherein said standard source comprises a counter, and seventh means for stepping said counter each time an item of digital information is read from said first means.
Claim 5
Dependent Claim 53 words
The apparatus defined in claim 2 wherein the information recorded on said first means is a recurrent pattern of information, and wherein said standard source comprises a rEcord containing said recurrent pattern of information, and seventh means for synchronizing the reading of the information from said first means and from said standard source.
Claim 6
Dependent Claim 131 words
Apparatus for checking the order of documents contained in a file of many documents, said apparatus comprising a coating of magnetizable material applied along at least one exposed edge of said file, first means for recording on said magnetizable material sequential information in the form of magnetic pulses so arranged that the edge of each of said documents contains a different item of magnetic information, a standard source of said sequential information, a second means for reading the magnetically recorded information from the edge of said file, a comparison means, and third means for applying the information read from the edge of said file and information from said standard source to said comparison means simultaneously and in sequence so that said comparison means indicates when said two inputs do not coincide.
Claim 7
Dependent Claim 131 words
Apparatus for checking the order of documents contained in a file of many documents, said apparatus comprising a coating of magnetizable material applied along at least one exposed edge of said file, first means for recording on said magnetizable material sequential information in the form of magnetic pulses so arranged that the edge of each of said documents contains a different item of magnetic information, a standard source of said sequential information, a second means for reading the magnetically recorded information from the edge of said file, a comparison means, and third means for applying the information read from the edge of said file and information from said standard source to said comparison means simultaneously and in sequence so that said comparison means indicates when said two inputs do not coincide.
Claim 8
Dependent Claim 17 words
The apparatus defined in claim 5 wherein said sequential information comprises a series of numbers in sequence.
Claim 9
Dependent Claim 35 words
The apparatus defined in claim 6 wherein said standard source comprises a counter, and fourth means for stepping said counter each time a new item of information is read from the edge of said file.
Claim 10
Dependent Claim 52 words
The apparatus defined in claim 5 wherein said standard source comprises a separate record containing information arranged in the same order as the information recorded on the edge of said file, and fourth means for synchronizing the reading of the information from the edge of said file and from said separate record.
