ABSTRACT:
A typewriter baseplate attachment for generating electrical signals that identify operations performed by the typewriter wherein, through the actuation of solenoids located in the baseplate attachment, the keys of the typewriter can be depressed to initiate the functional operations without the characters associated with the keys printing on the paper in the typewriter. This non-printing is effected through solenoid actuation of the correcting mechanism of the typewriter and suppression of the backspacing movement that normally accompanies operation of the correction mechanism.
