ABSTRACT:
A mechanism for controlling functions such as step-by-step carriage return, line spacing and rapid carriage return in a typewriter comprises a single cam adapted to oscillate a single actuating member. The actuating member carries a selector which can be positioned to selectively actuate levers controlling the various functions. The selector is positioned by a single lever which is tilted by different amounts by sliding bars each associated with a key corresponding to a given function. In its rest position, said lever locks the actuating member with the cam disengaged from a driving roller.
