Abstract
A data recording instrument having a recording sheet supply roll and a recording sheet take-up roll used for continuously recording a sensor. The instrument utilizes an axially movable rod activated by pulsing means. Movement of the rod advances the take-up roll through lever means connected to the axially movable rod. The lever means adjusts the degree of turning of the take-up roll in proportion to the amount of recording sheet accumulated on the take-up roll. The axial movement of the rod also activates marking means for charting the resultant output of at least one continuous sensor.

A data recording instrument having a recording sheet supply roll and recording sheet take-up roll for charting at least one continuous sensor comprising:
- a. rod movable along its axis in both directions,
- b. lever means for turning the take-up roll, said rod engaging said lever means thus turning the take-up roll during movement of said rod along its axis, said lever means adjusting the degree of turning of the take-up roll in proportion to the amount of the recording sheet accumulated on the take-up roll,
- c. marking means for impressing on the recording sheet the resultant output of at least one continuous sensor, said marking means connected to said rod and activated upon axial movement of said rod,
- d. pulsing means for axially moving said rod.
