Patent

CA 1122138

Abstract of the Disclosure Composer apparatus is disclosed in which machine readable representations of characters typed on the first part of a page are thereafter typed on a second part of the page. Key stroke signals generated by the typewriter keyboard are stored in a memory prior to being applied to access corresponding type ball positioning signals within a table to print the characters using a conventional type ball on the fir t portion of the page. Thereafter, the conventional type ball is replaced by a special type ball and the key stroke signals stored in the memory are used to access corresponding ones of a different set of type ball positioning signals within a second memory to enable the special type ball to type optically readable binary coded representations of the characters on the second part of the page. Each character is represented by a string of seven bits plus a parity bit which are typed using either a single strike of a group of eight bits on the special type ball or two different strikes using two different groups of four bits on the special type ball.
