Abstract
In an echo-sounding recorder wherein received echoes are recorded on a common recording surface, starting from a common zero mark, by means of a recording member moving with uniform velocity, the echo-sounding recorder being switchable to different depth-measuring ranges, respective switching members operable independently of one another for setting the recorder to different main measuring ranges and to different offset measuring ranges, and a scale associated with each of the measuring ranges, the improvement therein includes a scale carrier carrying all of the scales in a common plane, the scale carrier being formed of at least two parts respectively displaceable vertically and horizontally relative to one another, a cover plate disposed in front of the scale carrier parallel to the recorder and formed with a row of windows spaced from one another a distance corresponding to the distance between divisions of the respective scales, the scale carrier being mounted for movement relative to the cover plate in two mutually perpendicular directions disposed in the common plane of the scales over a distance corresponding to the scale offset, and kinematic transmission means for coupling the scale carrier to the switching members so that actuation of one of the switching member moves the scale carrier in one of the mutually perpendicular directions, and actuation of the other of the switching members moves the scale carrier in the other of the mutually perpendicular directions, each of the movements of the scale carrier being equal to the respective horizontal and vertical offset of the scales or a multiple thereof.
