ABSTRACT:
An electric control device for printing apparatus in which electric signals, representing letters and the positions of words formed by the letters, are transmitted from a keyboard to storage means in which the signals are stored in their sequence of generation. The storage means includes two one-character, seven-bit dynamic shift registers, coupled in series, through which the signals are shifted. A typewriter printing mechanism is coupled to the storage means, and it prints the stored text word by word, each formed by the letters represented by the signals stored in the storage means. A control unit coupled to the printing means, keyboard and storage means controls the input of the signals to the storage means, and the read-out and printing of the signals by the printing means, so that the signals are transmitted into and out of the storage means and printed word by word in the sequence in which they were generated.
