<p>In an apparatus for recording lines on a movable record carrier, a biased recording pin, whose point is urged into contact with the record carrier, is mounted in two knife edge bearings for longitudinal and angular movement. One bearing is stationary, and the other mounted on manually operated setting lever which can be operated to place the recording pin in different angular recording positions for recording lines on parallel tracks of the record carrier. The recording pin can be oscillated with a resilient arm to make a zig-zag beam-shaped recording.</p> |
