Abstract: PAPER INSERTION APPARATUS FOR A TYPEWRITER Paper insertion apparatus for indexing a typewriter to a desired first line printing position is triggered using a position detector cooperating with an operator movable paper hold-down bail. When the paper bail is moved to a withdrawn position relative to the paper feed path, the detector produces a signal that causes a logic processor to access, from a dedicated storage location, a code indicating paper advancing increments corresponding to a desired first line printing position. The processor then commands an indexing drive to advance that number of increments. In a preferred implementation, the operator can condition the typewriter to receive a new first line code into storage by means of the keyboard. By so using the presence of the paper bail in a withdrawn position to input the operator's paper insertion request, problems of automatically clearing the path for the leading paper edge are averted and the natural association of the paper bail with paper handling is exploited. And, by using the keyboard to indicate a desired first line position, special input devices such as dials or positionable selection levers are not required. LE9-78-021
