Abstract
Apparatus for coding input data characters from a keyboard incorporates apparatus for recognizing characters which are to be represented by two successive code representations, rather than the usual single code representation for each character. When a two-code character is recognized, ordinary operation of the apparatus is inhibited, and an auxiliary counter is energized which, in conjunction with a fixed-value storage device, causes the plural code signals to be generated in the correct sequence, after which normal operation of the apparatus is resumed.

Apparatus for the input coding of keyboard data characters comprising, a keyboard having a plurality of row lines and a plurality of column lines, means for interconnecting a row line with a column line in response to the depression of a key of the keyboard, counter means for sequentially manifesting coded representations of all of the keys of said keyboard, normally operative means for transmitting a said coded representation to an output at a time corresponding to the representation by said counter means of an operated key of said keyboard, detector means for detecting codes representative of special characters, means for inhibiting transmission of the special character-representative code, an auxiliary counter, means for initiating operation of the auxiliary counter in response to detection of a code representative of a special character, and means interconnected with said auxiliary counter for transmitting coded representations produced by said main counter at times when said representations correspond to plural code representations to be substituted for said special character-representative code.
