  • an indicia generator for the digitalizing of the indicia pursuant to prescribed segment-code and the generation of control impulses for the recording instrument. which determines the time points and duration of the indicia segments reproduction.
  • the impulse transmitters are controllable through a control installation in the sense of the succession of the segments of the tobe-recorded indicia for pressing the recorder against the recording strip. and wherein the number of the recorders are selected in conformance with the desired degree of reproducing precision for the indicia.

  • ink vapor recording arrangements of that type there are also known a large number of other recording arrangements which. in view of the relatively large mechanical inertia of the recorders. do not allow for rapid deflection or deviating movements of these recorders above the recording strip. as for example in the ink vapor recorder according to the German Laid- Open Patent Specification.
  • the application of the analogical deflecting impulses of the recorder pursuant to the German-Laid Open Patent Specification to recording arrangements of that type would then lead, for example, to the blending in of undesirable vertical lines. and thereby to falsification of the indicia.
  • the mentioned recording arrangements are, for example. such recording arrangements in which, for recording. the recording instrument must be directly pressed against the recording strip and. in particular. pencil recorders with thermally sensitive paper serving as the recording strips.
  • an object of the present invention to also construct such recording arrangements which do not operate with an ink beam or vapor. so as to render these possible of the graphic reproduction of alphanumerical indicia. and in particular also through longitudinally and transversely extending lines.
  • the foregoing object is inventively attained in that. extending transversely of the direction of movement of the recording strip. there are positioned a number of segment recorders each having an impulse transmitter associated therewith. in which the impulse transmitters are controllable through a control installation in the sense of the succession of the segments of the to-berecorded indicia for the pressing of the recorder against the recording strip. and wherein the number of the recorders are selected in conformance with the desired degree of reproducing precision for the indicia.
  • the inventive arrangement of a number of segment recorders extending transversely relative to the direction of movement of the recording strip permits the reproduction of indicia without specialized deflection or deviating motion ofa recorder. for example a recording pen. above the recording strip and perpendicular to the direction of its movement. Since for reproduction of individual indicia segments the segment recorder need only be pressed against the recording strip. this affords an increase in the extent. as desired. of the recording arrangement for graphic reproduction of alphanumerical indicia from previously only applicable ink vapor recording arrangements into the sphere also of recording arrangements having pressure recorders.

  • the impulse generator and the monostable stepping oscillators are suitably connected to each other through the intermediary logic interconnecting elements so as to generate pressing impulses for the recorder for each coincidence between the impulses of the impulse generators and the stepping oscillators.
  • the recording arrangement according to the invention is suitably applicable to the recording of alpha-numerical indicia, as well as for the recording of measuring parameters, for example. body-action stresses ln this case, it is purposeful to divide the recording strip into a total of two recording segments, wherein one recording segment is provided for the reproduction of the indicia, and the other for the reproduction of the measuring parameters.

These outputs S, through S, are so correlated with the indicia segments S, through S, of the indicia which is to be recorded so that there is generated, for the to-berecorded indicia segments S, through 8, at the corresponding outputs S, through S, of the converter 22, a voltage impulse having a length in conformance with the overall indicia width In the absence of particular segments in an indicia, the associated outputs at the converter 22 indicate zero voltages with respect thereto.
