Record verification apparatus

Claim 2

A record verification apparatus for verifying information recorded as a block comprising a memory having a first storage position and a second storage position, first comparing means, coupled to said memory, for comparing information to be verified with information stored in the first storage position of said memory so as to store information indicative of coincidence or non-coincidence between these two pieces of information in the second storage position and, at the same time, store said information to be verified in the first storage position, means for producing first verifying information, means for producing second verifying information, and second comparing means coupled to said memory and to said means for producing said first and second verifying information for selectively carrying out the comparison between said first verifying information and said information to be verified stored in said first storage position and the comparison between said second verifying information and said coincidence or non-coincidence information stored in said second storage position.

Claim 3

A record verification apparatus for verifying information recorded as a block comprising a memory having a first storage position and a second storage position, first comparing means, coupled to said memory, for comparing information to be verified with information stored in the first storage position of said memory so as to store information indicative of coincidence or non-coincidence between these two pieces of information in the second storage position and, at the same time, store said information to be verified in the first storage position, means for producing first verifying information, means for producing second verifying information, and second comparing means coupled to said memory and to said means for producing said first and second verifying information for selectively carrying out the comparison between said first verifying information and said information to be verified stored in said first storage position and the comparison between said second verifying information and said coincidence or non-coincidence information stored in said second storage position.

Claim 4

A record verification apparatus for verifying information recorded as a block comprising a memory having a first storage position and a second storage position, first comparing means, coupled to said memory, for comparing information to be verified with information stored in the first storage position of said memory so as to store information indicative of coincidence or non-coincidence between these two pieces of information in the second storage position and, at the same time, store said information to be verified in the first storage position, means for producing first verifying information, means for producing second verifying information, and second comparing means coupled to said memory and to said means for producing said first and second verifying information for selectively carrying out the comparison between said first verifying information and said information to be verified stored in said first storage position and the comparison between said second verifying information and said coincidence or non-coincidence information stored in said second storage position.

Claim 5

A record verification apparatus as claimed in claim 1, in which said information to be verified is recorded as individual blocks on a magnetic tape, and said information of one block is continuously detected from said magnetic tape to be supplied to said first comparing means.

Claim 6

A record verification apparatus as claimed in claim 1, in which both said first and second storage positions of said memory include a plurality of equally corresponding columns so that the read-out and write-in of information can be carried out concurrently.

Claim 7

A record verification apparatus as claimed in claim 1, in which a keyboard having a number of character keys and a single DUP key is provided so as to produce said first verifying information in response to the striking of said character keys and to produce said second verifying information in response to the striking of said DUP key.

Claim 8

A record verification apparatus for verifying information recorded in block form comprising: a memory having a first storage section and a second storage section; first means, coupled to receive information to be verified, and responsive to the contents of said first storage section of said memory, for comparing the received information and the contents of said first storage section and supplying the result of said comparison, representative of the coincidence or non-coincidence of the received information and the contents of said first storage section, to said second storage section of said memory to be stored therein, said result being thereby stored in said second storage section; second means for producing first verifying information; third means for producing second verifying information; and fourth means, responsive to the contents of said first and second memory sections and being coupled to said second and third means, for comparing the contents of said first memory section with said first verifying information and the contents of said second memory section with said second verifying information and for generating signals representative of the results of the latter comparisons.

Claim 9

A record verification apparatus for verifying information recorded in block form comprising: a memory having a first storage section and a second storage section; first means, coupled to receive information to be verified, and responsive to the contents of said first storage section of said memory, for comparing the received information and the contents of said first storage section and supplying the result of said comparison, representative of the coincidence or non-coincidence of the received information and the contents of said first storage section, to said second storage section of said memory to be stored therein, said result being thereby stored in said second storage section; second means for producing first verifying information; third means for producing second verifying information; and fourth means, responsive to the contents of said first and second memory sections and being coupled to said second and third means, for comparing the contents of said first memory section with said first verifying information and the contents of said second memory section with said second verifying information and for generating signals representative of the results of the latter comparisons.

Claim 10

A record verification apparaTus according to claim 5, further including means for supplying said information to be verified in individual blocks on magnetic tape, and means for continuously detecting the information in an individual block on said tape and supplying said detected information to said first means.

Claim 11

A record verification apparatus according to claim 6, wherein the storage positions of said first and second memory sections correspond to the positions of the increments in an individual block.

Claim 12

A record verification apparatus according to claim 5, wherein said fourth means comprises a first comparing section, for comparing the contents of said first memory section with said first verifying information and an AND gate for comparing the contents of said second memory section with the output of said third means.

Claim 13

A record verification apparatus according to claim 7, wherein said fourth means comprises a first comparing section, for comparing the contents of said first memory section with said first verifying information and an AND gate for comparing the contents of said second memory section with the output of said third means.
