PURPOSE:To obtain an easy-to-read printing format by printing data separately, unit by unit, by several lines at a time. CONSTITUTION:With a numeric key signal KBS, a controller stores a control signal CR1 in a register R1. Under the control of control signals CR1 and CDiS, the data of the register R1 is transferred to a display device DiS. With other numeric keys, the data is stored in the register R1 similarly. Then, when an addition instruction and a key signal KBS are sent to a control unit CPU, control signals CR1, CR2 and CALU enter the registers R1 and R2, and an arithmetic controller ALU, and the sum of the data of the register R1 and that of the register R2 is stored in the register R2. Then, control signals CPBR and CR1 are sent to a printing buffer register PBR and the register R1, and the addition data of the register R1 is transferred to a PBR. |
