ABSTRACT:
A pen recording apparatus provided with a plurality of ball point pens of different colors, and a pen section mechanism for selecting a suitable ball point pen for writing characters, symbols, etc., and drawing graphs. The recording apparatus can be switched between a typing mode, in which characters, symbols, etc., are typed, and a graphic mode, in which graphs are drawn. The recording apparatus includes a writing control device whereby, when the recording apparatus is switched from the graphic mode in which a graph is drawn in a plurality of colors to the typing mode, a ball point pen of the color originally disposed in the writing position when the recording apparatus was switched previously from the typing mode to the graphic mode is automatically disposed in the writing position, regardless of the colors of the ball point pens used in the graphic mode.
