Recording arrangement for the graphic reproduction of alpha-numerical indicia on a recording strip

Claim 1

In a recording arrangement for the graphic reproduction of alpha-numerical indicia on a recording strip formed of thermally sensitive paper, which is movable relative to a recorder means, comprising indicia generating means for digitalizing the indicia pursuant to seven segment-code; and means generating control impulses for the recording means for determining the time points and duration of the reproduction of the indicia segments, the improvement comprising; five segment recorder means each including a heatable stylus and being positioned transverse to the direction of movement of said recording strip, said recorder means including two exterior and one intermediate recorder means in spaced relationship for reproducing said longitudinal lines on said recording strip, and a recorder means for reproducing transverse lines being positioned between each said exterior recorder means and said intermediate recorder means, said recorder means reproducing said indicia through mutually perpendicular longitudinally and transversely extending liNes on said recording strip, said recorder means for the longitudinal lines having a writing width in conformance with the intended longitudinal line thickness, and said recorder means for the transverse lines having a writing width in conformance with the intended transverse line lengths, said styli comprising thin resilient leaf springs, stationary support means clampingly engaging one end of said leaf springs, the other ends of said leaf springs being movable relative to said recording strip; impulse transmitter means being associated with each of said segment recorder means; lifting magnets associated with each of said styli, said lifting magnets being energized through impulses generated by said impulse transmitter means for imparting movement to said styli relative to said recording strip, said impulse transmitter means each including an impulse generator for generating base impulses having lengths in correspondence with the reproduction width of an indicia; and monostable stepping oscillator means generating inpulses adapted to be superimposed on said base impulses, the time point and duration of the reproduction of the respective segments of an indicia being dependent upon the lengths and occurrence time points of said superimposed impulses, logic interconnecting elements operatively connecting said impulse generators and said monostable stepping oscillators for generating pulses pressing said recorder means against said recording strip at each coincidence of the impulses of said impulse generators and said stepping oscillators; and a control installation operatively connected to said impulse transmitter means for controlling the latter to effect pressing of said recorder styli against said recording strip with respect to successive segments of the indicia being recorded.
