ABSTRACT:
A laser computer output microfilmer wherein vertical and horizontal misalignment errors between the superimposed data character images and a format slide image are electrically corrected by appropriately incrementing or decrementing the presetting inputs of respective vertical and horizontal counters pulsed by line scan synchronizing and clock signals. This effectively shifts the projected data character frame by advancing or delaying the character generation start time and/or the line scan start time.
