Abstract:
An editing typewriter system using a record medium includes record mode signal means providing a record mode signal, edit mode signal means providing an edit mode signal, and control logic. The control logic includes means responsive to the record mode signal to record onto a record medium a position signal and a first set of data signals in precise relationship, means responsive to the edit mode signal to read a previously recorded position signal from the record medium, and means responsive to the edit mode signal and to the reading of the previously recorded position signal to record onto the record medium a replacement set of data signals superimposed on the first set of data signals; the previously recorded position signal and the replacement set of data signals are recorded on the record medium in precise relationship.
Abstract:
A sensor for punched cards and the like providing arrays of self-cleaning contacts of high reliability economically fabricated from standardized modular components. Contact combs having a linear set of bifurcated contact fingers are interleaved with spacers to form a planar array of contact pairs.
