Abstract
Disclosed is a control mechanism and device for conditioning a typewriter to backspace on every other depression of a keylever and at the same time to prevent printing on all depressions of keylevers. Additionally, the typewriter is conditioned to not print on those cycles in which a backspace movement is not included. This control mechanism and system allows the typist to key headings and other materials which would normally be centered in a no print mode and upon the completion of keying the entry once and switching into a normal typing mode, the typewriter is properly positioned with respect to the page for immediate rekeying of the heading or entry to provide centered copy.
