<p>PURPOSE:To facilitate an easy correspondence for each conversion during a unit conversion, by printing a unit conversion mark on the recording paper when a data conversion key is pushed. CONSTITUTION:With a push of each key, a keyboard part KB transmits the corresponding key signal to an arithmetic circuit part L. The part L carries out the arithmetic processing in response to the key signal sent from the part KB. An ROM stores the microinstruction information to perform control successively. An arithmetic part U carries out the arithmetic processing in accordance with the information given from the ROM. A print control part PC drives a printer P by a command given from the part U and stores the signal which drives a thermal head. The part PC contains a character generator CG which stores the dot patterns of characters to be printed, a motor control part MC which control a pulse motor, a thermal head control part HC, etc.</p> |
