A tray, or chute, that accepts input to a mechanical device, such as a disk duplicator or printer. In the days of punch cards, millions of cards were numerically or alphabetically organized by placing them into the hopper of a card sorter, taking them out of all the stackers and putting them back into the hopper for the next card column.
Sorter Hopper
In the 1940s and 1950s, millions of punch cards were placed into hoppers on IBM sorters such as this one. The hoppers were also fitted with two-foot extensions that held more cards. (Image courtesy of The Computer History Museum, www.computerhistory.org)
