Recording instrument marker mounting assembly is provided so that the marker can be pivoted relative to a mounting leg of the assembly which mounting leg is to be connected to an operating shaft of the recording instrument. In this manner, the lateral position of the marker can be adjusted relative to the recorder paper or chart which is to be imprinted upon. The mounting assembly comprises a mounting leg to be connected with the operating shaft, a cam connecting a marker support arm and the mounting leg, and cam follower means positioned on the support arm. Pivotal movement of the support arm relative to the mounting leg is actuated by rotation of the cam. In a preferred embodiment of the invention, the cam is formed integrally with a manually engageable precision adjustment knob, which includes a notch or the like so that the operator may gauge the position of the marker relative to the mounting leg.
