ECR with data memory structure for transmitting sales data and re-stock data to an external unit
First Claim
1. An electronic cash register for transmitting sales data and commodity re-stock data to an external unit, comprising:
- a keyborad (1) having a plurality of keys including numeral keys (1a), a data write key (1b) and a transmission key (1e);
a central processing unit (3) coupled to said keyboard and including input data storage means (X) for storing input data, which is input by operation of numeral keys on said keyboard, and format data memory means (P) for storing the number of digits of each of a plurality of data items required for transmission of said commodity data;
sales data memory means (A, B, C) coupled to said central processing unit for storing various accumulated totals of sales data input from said keyboard;
additional data memory means (T), coupled to said central processing unit for storing, in format ready for transmission, commodity data items in numerical or numerically coded form obtained from said input data storage means; and
transmission control means (6) coupled to said central processing unit and to said sales data and additional data memory means and including means for transmitting data from said central processing unit to said external unit;
said central processing unit including;
means for reading out the digit number data of each item of said commodity data from said format data memory means (P);
means for checking each commodity data item in said input data storage means with said digit number data for format requirements and for checking said additional data memory means to assure the presence of available memory areas therein having a size corresponding to said digit number data;
means for writing into said available memory areas a commodity data item stored in said input data storage means after said commodity data item is successfully checked by said data and memory checking means;
means responsive to operation of said data key on said keyboard after a commodity data item has been stored in said input data storage means for activating, in turn, said digit number data read-out means, said data and memory checking means and said data writing means, andmeans responsive to operation of said transmission key on said keyboard for causing said transmission control means to transmit to said external unit the commodity data composed of items in accordance with said format data memory means and written into said memory areas of said additional data memory means.

Abstract
An electrical cash register is disclosed, which is provided with a numerical data memory in which sales data input from a keyboard are successively accumulated, and also in which commodity data for different items input from said keyboard are stored when a particular key on the keyboard is operated. When a data transmision key on the keyboard is operated, the sum of sales data and commodity data stored in the numerical data memory are transmitted to an external apparatus. Before commodity data is transmitted, its format requirement (digit number length) is checked and commodity data memory availability for the particular requirement is also checked.
