摘要

A system for sequentially reading the notched edge code on a microfiche carrier compensates for lateral misalignment of the carrier by the use of multiple banks of fiber optic code sensors. The appropriate bank is energized by use of additional sensors for a code guide formed on the carrier. A prescribed field of view also accommodates bowing of the carrier. Use of fiber optics reduces the need for complicated lenses.
