Abstract
Indicator device for a recording device for measuring the time used by echoes, in an inscribing body that is moved periodically and at a uniform speed, in a straight line, on the inscription surface, indicating facility that is provided with a device for continuous movement from the instant of sound emission as well as a marker device intended to characterize the partial sounding field, characterized in that a scale film which is displaceable in a manner known per se is arranged on the inscription surface in accordance with the displacement of the moment of the emission of the sound, transversely to the direction of movement of the inscription strip and that, in addition, for the interpretation of old inscriptions still visible on the inscription surface, can be displaced in the longitudinal direction of the inscription strip.
