Abstract
A recording apparatus for writing characters in a writing mode and plotting graphs in a plotting mode, with a writing instrument supported on a reciprocating carriage, based on input data through a keyboard which is operable in a first mode in which at least numerals are keyed in, and in a second mode in which letters and symbols are keyed in. The apparatus comprises a control device for controlling a paper feeding device and the carriage, to write in the writing mode the characters which are keyed in through corresponding character keys with the keyboard placed selectively in the first mode or in the second mode, and to plot the graphs in the plotting mode based on the operations of the keys with the keyboard placed in the first mode. The apparatus further comprises a memory means for storing, upon selection of the plotting mode, mode data indicative of one of the first and second modes of the keyboard which has been established in the writing mode before the plotting mode is selected, and an automatic mode setting device for placing the keyboard into the first mode upon selection of the plotting mode, and placing the keyboard, upon selection of the writing mode, into the first or second mode which is represented by the mode data stored in the memory.
