.~ Serial read-out from full bank of pattern-sensers
DEFINITION
Classification: 234/66
(under subclass 59) Device which includes a plurality of sensing means arranged to coact simultaneously with all significant points of a pattern field, and further including means effective to establish, in sequence, a plurality of signal or impulse transmission channels, each extending from a group of such sensing means to the tool selecting means or to a portion thereof.
(1) Note. Fig. 15 illustrates typical mechanism found in a device of this subclass. A pattern card is clamped in a sensing unit which may comprise a full bank of spring-biased sensing pins. Movement of the sensing unit and pattern past a microswitch causes successive positionings of interposer I corresponding to those sensing pins which have entered holes in the pattern and are thus misaligned with the others. Storage* is not involved here, for the input-impulses* are retained (by the positioned sensing pins) until tool selection has been effected. [figure] [caption]Fig. 15.
