The class of machines variously called Reproducing Punches, Summary Punches, Gang Punches, and/or Document Originating Machines included the IBM 513 (date unknown) and 514 (1945) Reproducing Punches, the Type 516 (1932, intended as a Summary Punch for the 285), the IBM 519 Document Originating Machine (1946) (CLICK on any image to magnify), and the IBM 526 Printing Summary Punch. These machines performed a variety of tasks, according to the wiring of their control panels:
Reproducing | Copying all or selected information from one deck of cards to another deck of cards, possibly rearranging the fields. |
Gang Punching | Copying information from one input card to many output cards. |
End Printing | For example, of sequence numbers. |
Verification | Of reproducing and gang punching results. |
Summary Punching | Punching into a total or new balance card sums accumulated in an attached accounting machine such as the 403 (shown below) or 405 or 407. |
Mark Sensing | Reading pencil marks from IBM cards and translating them into punches (optional feature). |
The 526 is a unique hybrid: it's an 026 Card Punch and Summary Punch and Interpreter combined. It's slower than a dedicated Summary Punch (18 columns per second = 15 cards per minute) but it prints as it punches and it doubles as a key punch.
