Abstract
Abstract A teller machine is capable of modifying information stored within a secondary memory when the operator realizes a mistake even after he has completed transactions and placed information with respect to these transactions into the secondary memory. In the teller machine, a primary memory stores numerical information representative of amounts of money after each transaction and a secondary memory stores cumulative amounts of money for all transactions.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
309 words
A teller machine comprising: input means for introducing numeral and function individual transaction data of each individual transaction introduced into said teller machine; processing means responsive to said individual transaction data introduced by said input means for performing calculations for each individual transaction and thereby producing transaction results; first memory means responsive to said processor means for storing therein the individual transaction data and transaction results of each individual transaction; second memory means responsive to said first memory means for storing a cumulative representation of all transaction results performed over a period of time; said input means introducing error information related to errors made in the introduction of individual transaction data of at least one individual transaction; said processor means comparing said error information with said individual transaction data stored in said first memory to detect a coincidence with said individual transaction data; modification means responsive to said input means for correcting the transaction data and transaction results of said at least one individual transaction having data erroneously entered, said modification means including, means responsive to said input means and the detection of a coincidence by said processor means for subtracting said transaction results of said erroneous individual transaction from said cumulative representation in said second memory means, means responsive to said input means for adding the transaction results produced by said corrected transaction information to said cumulative representation in said memory means, and switch-over means for enabling said means for adding after said erroneous transaction results are subtracted by said means for subtracting; cancel marking generator means responsive to the operation of said modification means for producing a cancel marking on the printed transaction results; means responsive to said input means for retrieving and printing the transaction results stored in said first memory means and the cumulative representation of teller transaction results stored in said second memory means.
Claim 2
Dependent Claim
309 words
A teller machine comprising: input means for introducing numeral and function individual transaction data of each individual transaction introduced into said teller machine; processing means responsive to said individual transaction data introduced by said input means for performing calculations for each individual transaction and thereby producing transaction results; first memory means responsive to said processor means for storing therein the individual transaction data and transaction results of each individual transaction; second memory means responsive to said first memory means for storing a cumulative representation of all transaction results performed over a period of time; said input means introducing error information related to errors made in the introduction of individual transaction data of at least one individual transaction; said processor means comparing said error information with said individual transaction data stored in said first memory to detect a coincidence with said individual transaction data; modification means responsive to said input means for correcting the transaction data and transaction results of said at least one individual transaction having data erroneously entered, said modification means including, means responsive to said input means and the detection of a coincidence by said processor means for subtracting said transaction results of said erroneous individual transaction from said cumulative representation in said second memory means, means responsive to said input means for adding the transaction results produced by said corrected transaction information to said cumulative representation in said memory means, and switch-over means for enabling said means for adding after said erroneous transaction results are subtracted by said means for subtracting; cancel marking generator means responsive to the operation of said modification means for producing a cancel marking on the printed transaction results; means responsive to said input means for retrieving and printing the transaction results stored in said first memory means and the cumulative representation of teller transaction results stored in said second memory means.
Claim 3
Dependent Claim
145 words
The teller machine of claim 1 wherein said input means includes a transaction correction key; and wherein said switch-over means includes; first and second pairs of AND gates; and first and second inverters; a first input of one of said AND gates of each pair being connected to said first memory means; a first input of the other of said AND gates of each pair being connected to said second memory means; the second input of each of said AND gates being connected to the transaction correction correction key through said first and second inverters, said key producing a high signal when correction is desired; the output of said AND gates of one pair being connected to an input of said means for adding and the output of said AND gates of said other pair being connected to an input of said means for subtracting.
