Handling Device for Punched Card Microcapacity Memory

This device changes a punched card in a pile type microcapacity memory. Such a memory is a stack of identical units each composed of a punched card 3. This is sandwiched between a column printed circuit 1 and a line printed circuit 2, and a handling device 5.

The whole system slides vertically along column 4. Plate 5 alone also slides horizontally, being provided with an oblong hole. Normally, all plates 5 are in the closed position and the stack is pressed with a spring locking device.

When a punched card is to be changed, the locking device is released and plate 5 corresponding to the card to be changed is pulled. Ball 6, which is normally in the conic hole of plate 5, is raised and separates plate 1 from plate 2 by about 1/32 of an inch. Card 3 can then be removed and another one can be put in its place. Then plate 5 is replaced in its original position close to card 3. After tightening the locking device, the memory is again in its operative state.
