Abstract

PURPOSE: To omit the printing process for the unnecessary data at the correction time by providing the buffer to memorize temporarily the process result for printing and then printing the contents of the buffer with delay of one operation time to the operation of the function key.
CONSTITUTION: The correction key 12 is operated, and the correction code is written into the 15th digit of register A of CPU20. Then the correction code is transferred to the display buffer within I/O port 22, and segment signal SG is sent to display part 24. The contents of the department-based memory of "02" in RAM21 are read out to register B of CPU20, and the contents of register A, i.e., the amount registered at this time is subtracted from the contents of register B to give correction to the department-based memory. At the same time, the contents of register A are subtracted from register C, and then the correction is given to the subtotal amount for the transaction. Then the contents of register D are cleared to complete the process to the correction key.
