ABSTRACT:
A microfilm comprises a plurality of microimages continuously formed on a film base thereof, each of the microimages being provided with a size mark which has a distinctiveness for indicating the size of the corresponding microimage. A printer adapter for use with such a microfilm comprises a sensor for detecting the size marks. Correct size coping sheets are, therefore, supplied in accordance with the signal from the sensor.
