Abstract

Abstract Disposable fiber tip marker means for a flat bed plate type recorder includes first and second markers each comprising a fiber tip pen and cartridge, each cartridge having a flat base wall which is disposed at an angle of 17* with respect to the plane of a recorder chart. The fiber tip pen associated with each cartridge extends at substantially a right angle from the related base wall. Each cartridge also includes a second flat wall which extends at an obtuse angle from said base wall. The cartridges are arranged with each of said second walls disposed in adjacent and parallel planes and with the fiber tip pens thereof extending substantially to said planes whereby each fiber tip pen is capable of recording on substantially the same time line of said chart.
