(under subclass 59) Device comprising means for effecting relative progressive movement between the pattern and the sensing means during the sensing operation.
(1) Note. Either or both of the pattern or the sensing means may move (e.g., pattern card or tape sensed while in motion through the device, or a stationary record "scanned" by moving pattern sensers.
(2) Note. As an alternative to moving the pattern or the sensers, all points of a stationary pattern may be sensed simultaneously and the data may be read out in steps (e.g., column-by-column) to the tool-selecting means, over a system of shiftable connections (see subclass 66).
SEE OR SEARCH THIS CLASS, SUBCLASS:
25, for pattern-sensing means which may be disclosed as operating upon a moving pattern.
64, for a gang-punching* machine which may disclose the sensing of a card in motion. 66, for means to read data in sequential steps from a full bank of pattern sensers, and see (2) Note, above.
