DEFINITION

Classification: 234/26

(under subclass 25) Device wherein said control-imposing means governs the transfer or nontransfer of data from a pattern to a workpiece, the device being further provided with a comparator effective to compare data sensed by such additional means with other data stored in the device or concurrently sensed from a pattern or workpiece, and means to initiate the control-imposing signal or impulse under a given condition of correspondence or noncorrespondence of said compared data.

(1) Note. The auxiliary-operation controlled in this case is the tool actuation (as distinct from tool selection) or the transmission of selection impulses to the tool-selection means.
