ABSTRACT:
A writing-plotting apparatus with a keyboard capable of writing characters in a writing mode, and plotting graphs in a plotting mode, comprising a carriage carrying a writing instrument such a ball-point pen movable toward and away from a sheet of paper, a first memory for storing character pattern data representative of characters, a second memory for storing graphic pattern data representative of patterns of graphs, and a control device which, in the writing mode, reads out from the first memory the character pattern data corresponding to the operated character keys, and in the plotting mode, reads out from the second memory the graphic pattern data. The control device is responsive to the read-out character or graphic pattern data to control the operations of drives for feeding the paper along one axis, and reciprocating the carriage along another axis perpendicular to the one axis. The apparatus further comprises a display device which displays, in the writing mode, the keyed-in characters, and provides, in the plotting mode, messages relating to a procedure according to which data necessary to plot a graph is entered through the keyboard.
