Abstract
Abstract An electronic cash register according to the present invention stores price data on commodities inputted through ten keys (12) and department codes inputted through department keys (13) in a buffer (631) of a RAM (6) and thereafter store the data stored in the buffer (631) of the RAM (6) in a floppy disc (7) and transfer the same to a host computer (8) when a customer requests transaction processing through a credit card and an A key (143) or a B key (144) is operated. Therefore, the transaction data can be stored in external storages only when the A key (143) or B key (144) is operated.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
282 words
An electronic cash register which can register in external storages only desired data from the data on registered commodities, comprising: input means for inputting data on commodities purchased by a customer; storage means for storing said data on commodities inputtted from said input means; external registration commanding means for generating a command for external registration of said data when said data is to be registered in said external storage; bit storing means responsive to said command from said external registration commanding means for storing a bit indicating that said data inputted from said input means is to be registered in said external storages; settlement command means for providing a settlement command of transaction when all of said data on commodities purchased by a customer has been completely inputted by said input means; and control means for controlling said data storage means such that each time said data on commodities is inputted by said input means, the inputted data is stored in said data storage means, for controlling said bit storage means such that said bit indicating that the external registration of said data is to be made is stored in said bit storage means in response to said command from said external registration commanding means, and for determining, in response to the command from said settlement command means, whether said bit indicating that external registration is to be made is stored in said bit storage means, and registering in said external storages a part or all of said data stored in said data storage means, if and when it is determined that said bit indicating that external registration of said data is to be made is stored in said bit storage means.
Claim 2
Dependent Claim
282 words
An electronic cash register which can register in external storages only desired data from the data on registered commodities, comprising: input means for inputting data on commodities purchased by a customer; storage means for storing said data on commodities inputtted from said input means; external registration commanding means for generating a command for external registration of said data when said data is to be registered in said external storage; bit storing means responsive to said command from said external registration commanding means for storing a bit indicating that said data inputted from said input means is to be registered in said external storages; settlement command means for providing a settlement command of transaction when all of said data on commodities purchased by a customer has been completely inputted by said input means; and control means for controlling said data storage means such that each time said data on commodities is inputted by said input means, the inputted data is stored in said data storage means, for controlling said bit storage means such that said bit indicating that the external registration of said data is to be made is stored in said bit storage means in response to said command from said external registration commanding means, and for determining, in response to the command from said settlement command means, whether said bit indicating that external registration is to be made is stored in said bit storage means, and registering in said external storages a part or all of said data stored in said data storage means, if and when it is determined that said bit indicating that external registration of said data is to be made is stored in said bit storage means.
Claim 3
Dependent Claim
26 words
An electronic cash register as claimed in claim 1, wherein there are a plurality of said external registration commanding means, each having a corresponding identification code.
Claim 4
Dependent Claim
28 words
An electronic cash register as claimed in claim 2, further comprising identification code storage means for storing said identification codes of said plurality of external registration commanding means.
Claim 5
Dependent Claim
82 words
An electronic cash register as claimed in claim 3, wherein said control means includes means responsive to a command from any of said plurality of external registration commanding means for determining whether said identification code corresponding to the external registration commanding means is stored in said identification code storing means and, if said identification code is stored therein, controlling said bit storing means such that said bit indicating that external registration is to be made is stored in said bit storage means.
Claim 6
Independent Claim
173 words
An apparatus capable of storing in external storages only selected data from registered commodities data, said apparatus comprising: (a) input means for entering said commodities data; (b) storage means for storing said commodities data received through said input means; (c) indicator means for selectively indicating which of said commodities data is to be stored in said external storages including bit storing means for storing a bit indicating that said commodities data entered from said input means is to be registered in said external storages; (d) command means for providing a command signal when all of said commodities data purchased by a customer has been completely entered through said input means; and (e) control means responsive to said command signal from said command means for determining whether the bit indicating said commodities data is to be registered in said external storage is stored in said storage means and transferring said commodities data indicated by said indicator means to said external storage, when said control means determines said bit is stored in said storage means.
Claim 7
Independent Claim
173 words
