Abstract

PURPOSE:To decrease the data transfer quantity, by previously storing the output data having a high using frequency and then extractig the stored data when the load code for call-out is transmitted. CONSTITUTION:The output data (comprising load code plus figure, header, word or sentence code) having a high using frequency and sent from a computer main body (not shown in the diagram) is supplied to a cntrol part 3 via an interface control part 1 and a data register part 2. Then an address is decided based on the figure code (n), and a header part H is stored in a head region 10 of the n-th storage region 11 in a memory 5. Thus a character code, quantity unit price and total amount are writen into the region 11. When no special code is detected in the data sent under such conditions, the data is written into a line buffer 6 via a selector 4. While if a special code is detected, the address of the region 11 is designated based on the figure code. Then the character code is read and written into the buffer 6.
