Abstract

There is an electronic cash register comprising a keyboard having numeral keys and first to fourth function keys, a first memory in which a plurality of character codes and a plurality of corresponding character patterns have been stored, and a data processing unit which generates sales data in response to the key operations in the keyboard and also reads out the character pattern from the first memory in accordance with the sales data and supplies it to a dot printer in the registration mode. In the program mode, the data processing unit stores the character code which is generated by operating the numeral keys and first function key into a second memory and stores the column address data which is generated by operating the numeral keys and second function key and the character pattern formed of the dot pattern which is generated by operating the numeral keys and third function key into the second memory. The data processing unit also transfer the character pattern stored in the second memory (in response to the operation of the fourth function key) into the memory area in the first memory that is designated by the character code stored in the second memory.
