PURPOSE:To provide the titled device which facilitates operations related to reprinting and prevents writing errors due to handwriting or the like, by providing a display part, a printing part, a register the content of which is changed in the manner of an arithmetic progression and a means for electronically correct the content of the register to the preceding state. CONSTITUTION:In the flowchart, numerical value information to be printed is stored in the register NR provided in an RAM, and an increase or decrease in numbering is stored in a numbering constant register NV. A numbering flag NF is a one-bit register storing an increase/decrease selecting flag, wherein ''1'' is established when designating an increase, while ''0'' is established when designating a decrease. First, an initial value for numbering is set in step (1), which value is increased by an increment of 1 when printing is conducted by operating a P key. Steps are proceeded in accordance with the flowchart. When a printing error is made, reprinting can be easily conducted by using a CI key. |
