Zusammenfassung:	A recording instrument is disclosed for measuring and recording changes in linear distance between two predetermined points. The instrument is comprised of a recording tape and a scribing means for marking the changes in linear distance on the tape. The scribing means moves in a direction which is transverse to the longitudinal axis of the tape. The instrument includes a tape housing means which accommodates the tape so that the tape is free to move along its longitudinal axis but is substantially constrained from transverse movement. The instrument additionally includes a tape drive means for longitudinally advancing the tape under the influence of both positive and negative changes in the linear distance. The tape drive means includes a linear motion amplifier and a reciprocating to rotary motion converter.
