Abstract

This punched card evaluator is used for optically scanning punched cards (6), preferably those with fine perforation. Each scanning channel of the device is assigned aligned openings (3, 10) in an upper and a lower plate (2, 11). In one plate opening a light source (1) is located and in the other one a light-sensitive sensor (12) is located. The openings are each terminated flush with the plate surface by a transparent sapphire (4, 9) or similar wear-resistant material so that the scanning channels cannot be plugged by dust or foreign bodies. The light flux is evaluated in such a manner that it is not the rise in light flux when a hole moves past the sensor but the drop in light flux, and thus the electrical output current, which is evaluated.
