发明名称 Referencing device for digital data recorders
摘要 An improved referencing device for identifying for future reference a portion of a data record as it is being recorded for use in combination with a shorthand machine generating electrical output signals corresponding to the keys depressed, a recording medium, and recorder associated with said shorthand machine for making a data record of the signals generated thereby on said recording medium. The referencing device comprises means for generating a reference signal separate and independent from the output signal generated by said shorthand machine and for inputting said reference signal to said data recorder for making a record of the referencing signal on the recording medium. A portion of the data record may then be identified for future reference by the reference signal record.
