Abstract

Improved apparatus for effecting semi-automatic insertion of paper into a typewriter concentrates operator interactions, (1) to condition the typewriter for a distance input selection and (2) to trigger indexing for paper insertion, so as to merely involve positioning of the paper bail. A detection of the paper bail at a predefined position withdrawn from the paper feed path conditions the typewriter to interpret keyboard actuations--preferably of the number keys--as representing desired first line distances e.g., the '2' key represents a first line one inch from the top of the sheet. And, in a presently preferred implementation, the number keys represent a fixed distance increment (three lines or approximately one half inch) multiplied by the key number. The represented distance, including any feed path distance to move the top of the sheet from the entrance point to the print line, is stored in memory and a transfer of the paper bail from the detected position then serves to trigger paper indexing that corresponds to the stored distance.
