ABSTRACT:
Apparatus for indicating the location of particular information, such as instructions, represented by predetermined signals previously recorded on a record medium. An array of light emitting sources is selectively energized to indicate the position of the particular information relative to the length of the record medium while the array is scanned in synchronism with the scanning of the record medium to detect the presence of such predetermined signals. Indexing means sequentially conditions each of the light emitting sources to be energized during scanning; and a temporary storage circuit stores a representation of a detected predetermined signal, until a light emitting source is conditioned.
