ABSTRACT:
A serial cassette changer in which the height and the width of a cassette in a cassette carriage are measured. The positions of two markers are controlled by levers which bear against the sides of the cassette, so that the angular positions of the markers are determined by the cassette dimensions. The angular positions of the markers are then "read" by an optical source and sensor by moving the cassette carriage (bearing the markers) across the field of view of the optical reader.
