Computer punch card reader


Accession Number: 1999.42.2

Description: Steel punch card reader into which the punched card is placed for reading by visually impaired programmers. A sliding bar, attached to the top frame of the reader, moves across the columns of holes in the punched card. A braille stylus is moved down into a vertical slot on the sliding bar until it drops into a hole in the card. The programmer feels the reference hole to the right or left of the vertical slot to determine the holes punched in each column. A click can be felt as the bar moves across a column. Notches in the frame of the card reader allow the sliding bar to move in 10 column increments. Column 1 can be read by sliding the bar all the way to the right; column 80 can be read by sliding the bar all the way to the left.
