ABSTRACT:
A keyboard in which, when one of the function keys is depressed simultaneously with one of the character keys, the signal generated by the depressed function key is transmitted during a first period of time following the key-stroke which depressed the keys, and the signal generated by the depressed character key is transmitted during a second period of time following the key-stroke which depressed the keys, the second period having an initial instant following the last instant of the first period. To achieve this result the character signal is delayed, so that an associated printer receives and is capable of performing the function commanded by the function signal before the printer is caused to print the character of the character signal which is subsequently received.
