ABSTRACT:
A combination electrosensitive reader-printer able to perform both functions by sensing the condition of a recording medium in the read mode and by altering the condition of the recording medium in the printing mode. The change of mode is accomplished manually or automatically. The data to be read or written may be coded optically or digitally for interpretation by a processor. The recording medium is a metalized paper or similar material with an ink under or over lay. The resistivity, conductivity or capacitance change of the medium is sensed or altered by the reader-writer. Appropriate timing tracks and registration marks are normally placed to enable reading and writing by different devices. The styli for reading and writing normally are disposed in an array, straight or angled relative to the paper path. The styli have tips which are cylindrical, rectangular or oval in cross section. Control circuitry, including an analog to digital converter, control input to and output from the reader-printer.
