1. Cue address generating means for use in signal editing apparatus of the type wherein signals recorded on a first record medium are transferred to a second record medium when preselected positions of said media are reached, said cue address generating means generating a cue address representing the position of one of said record media adapted to be accessed by signal recording/playback means, and comprising a plurality of display registers, at least one display register associated with said first medium and being operative to display position data representing a relative position of said first medium and at least another display register associated with said second medium and being operative to display position data representing a relative position of said second medium;

  • means for supplying position data to be displayed by respective ones of said display registers;

    a plurality of register selector means associated with respective ones of said display registers and thus associated with respective ones of said media, each register selector means being selectively operative to select its associated display register;

    at least one cue selector means associated with a respective one of said record media and selectively operative to initiate a cue address generating operation; and

    control means responsive to the operation of one of said register selector means and to said at least one cue selector means for (a) retrieving the position data displayed in a first display register associated with said first medium when the operated register selector means also is associated with said first medium and retrieving the position data displayed in a second display register associated with said second medium when the operated register selector means also is associated with said second medium, (b) subtracting the retrieved position data from the position data displayed in the display register selected by the operated register selector means to produce a difference signal, and (c) mathematically combining said difference signal with the position data displayed in a third display register to produce said cue address, said third display register being associated with the same record medium as that with which said selectively operated cue selector means is associated.
