  • Patent number: 4464070
    Abstract: A text recorder includes a multi-character display controller which is operated in a multi-character mode to record (e.g., print on paper or generate a CRT or the like display) multi-character sequences in response to operator actuation of a single key of a keyboard substantially identical to a conventional typewriter keyboard. Operator actuation of a key generates a coded signal representative of the actuated key, but in the multi-character mode, the normal text recorder function of printing or displaying the character associated with the key is inhibited, and instead, a memory device is accessed which has stored at a location corresponding to the actuated key, a sequence of coded signals representative of a plurality of characters, functions or both. The storage device may include a plurality of sets of stored signal sequences representing a plurality of multi-character sequences, the selection between the different storage sets being effected based on a particular key or key sequence previously actuated.
