Abstract

1316532 Typewriters INTERNATIONAL BUSINESS MACHINES CORP 1 Dec 1971 [30 Dec 1970] 55671/71 Heading B6F Error Correction.-Depression of an erase key 22 or a special back space/erase key (Fig. 3) causes the following simultaneous operations; (1) backspacing by one letter space, (2) shift of an erasure ribbon (152, Fig. 5) to an obliterating position, (3) prevention of an escapement for a single print cycle. The key corresponding to the imprinted error is then actuated to obliterate the error, during which operation no movement of the carriage takes place. This operation however resets the escapement mechanism so that when the correct character key is actuated, imprint takes place and the carriage is caused to advance one letter space. Dead key.-If the erasure ribbon mechanism is not included, the erase key 22 will act as a dead key. Specification 1,316,533 is referred to.
