Pens for low torque chart recorders

摘要

A disposable marker apparatus for use with low torque recorders includes a bifurcated body with two separate ink reservoirs in the first and second body segments interconnected by a connector segment. The connector segment includes an ink transmitting member. A stylus tube extends from the body. A pivot member is provided to engage an associate pivot support outwardly from said pen body. A substantial portion of the mass of the marker is below the connector segment and the pivot member. The result is a marker having a center of gravity below the pivot so that the swinging marker tends to stabilize after disturbance due to vibration or rapid marker excursion.
