Carrier Positioning

Operation of coded function keys and visual alignment of a scribed line on a card holder are substituted for platen and scale manipulation techniques, for accurately positioning a typewriter carrier along a writing line.

A normally clear plastic card holder is provided with a scribed line 3 picas to the left of the center of the print window. This line extends vertically through the writing line. Operator depression of a coded positioning key will cause forward carrier escapement 3 picas. The scribed line on the card holder will now be aligned with the print point defined at the time of depression of the coded key. The print point can then be relocated through spacing and backspacing the carrier.

When the scribed line on the card holder is aligned with the desire print point, a coded positioning release is keyed for causing the carrier to backspace 3 picas for printing at the desired print point. With the scribed line and coded keys, alignment is controlled entirely at the keyboard.
