ABSTRACT:
Disclosed herein is a multiple line writing instrument which is adapted for one-handed operation in the general manner of an ordinary pen or pencil and which accomodates variations in the writing angle at which the instrument may be applied to a writing surface. The instrument includes plural elongate writing means, such as pens, held in parallel, spaced apart array. By means of a pivotal stop table the writing tips of the plural writing means are held in continous writing contact with a writing surface despite variations in writing angle which may occur during use. The multiple line writing instrument avoids the necessity to employ biasing elements, such as springs, to maintain writing contact of the writing tips with the writing surface.
