Description

The invention relates to recording systems for continuously flowing; their processes in recording devices.

In existing self-feeding devices, recording is carried out with a pen of a food-type galvanometer on a recording medium (e.g., paper tape) that is continuously and evenly moving under the pen.

With this recording process, once the media has passed under the pen, it is no longer used, which entails significant consumption.

In the proposed device carrier. the ring which is glued together from paper tape repeatedly passes under the pen of a squeaking galvanometer, which ensures a very economical expenditure of the recording carrier material.

In order for each subsequent line (curve) not to be added to the previous record, the writing mechanism along with the pen should not be placed on a movable carriage that moves continuously and evenly in a directional direction perpendicular to the movement of the carrier.

As a result of movement in two mutually perpendicular directions of the two elements of the device — the carrier and the writing mechanism — the recording on the carrier is made along a helical line.

If you need to simultaneously record several readings on a movable carriage, several searching galvanometers may be placed.

Recording can be made both on a carrier glued into a ring from a tape, and on a carrier located on a drum.

The transfer of the recording medium and the carriage with galvanometers are kinematically connected and carried out from a common spring or electric motor. The change of the screw of the helix can be done, for example, with the help of interchangeable gears.
