Apparatus for converting information recorded on a magnetic recording sheet into visible information

摘要: A rotatably mounted drum is arranged to support a recording sheet with the columns of recorded information extending substantially axially drum, and magnetic reproducing head cooperable for movement drum. Photoelectric transducer means are operatively associated aligned respective information. Printing mechanisms, equal in number, preferably number photoelectric adjacent relation, each printing mechanism operative responsive cojoint operation detection an bit by head. In one embodiment invention, light source within aperture wall, transducers circumferentially consecutive activation as rotates. The connected parallel other operating mechanism. another single transducer, formed series apertures thereof, common radial plane being particular column input AND circuit whose output diode matrix which controlled reset type flip-flop, mechanisms.
