Abstract

PURPOSE: To enlarge an application range of a typewriter by providing two modes, that is, a mode of printing numerical formula and answer and another of printing only answer.
CONSTITUTION: In an electronic typewriter with a computer mode, in which an action of the typewriter and a computing function are controlled in response to an input from a keyboard, there are provided two modes, that is, a mode for printing both a numeral and an answer and another for printing only the answer. By this constitution, when a key code supply operation from the keyboard is carried out at 1, whether or not a current is supplied to the key for a change-over of two modes is judged at 2, and presence or absence of the mode change-over is memorized at 3. In carrying out the computation processing by 10, the presence or the absence of the mode change-over is judged, and processing whether only the answer is printed by 11 or the numerical formula and the answer are printed is performed.
