PURPOSE:To facilitate easy discrimination between an arithmetic result data and an addition/subtraction data printed in an ordinary way and at the same time to save the printing work, by printing the arithmetic result data in bold letter. CONSTITUTION:When an addition/subtraction end key is pushed, a key signal KBS is fed to a control unit CPU. The unit CPU transmits control signals CR1 and CR2 to registers R1 and R2 respectively and transfers an addition/subtraction result data 1234567890. stored in the register R2 to the register R1. Then the CPU stores 0 to the R2, and control signals CPRT and CR1 are fed to a printer PRT and the register R1. Then the addition/subtraction result data of the register R1 and a print symbol * are transferred to the printer PRT. After detecting that the print symbol is ''*'', the data 1234567890. sent from the register R1 is printed in bold faces together with the symbol *. |
