Line Position Reference

Document 10 is manually inserted between platen 15 and type element 20. This is such that the last line of printing on document 10 aligns with reference light beam 21. With document 10 so aligned, printing takes place upon the next line.

Beam 21 is produced from light source 25 through the facility of Shutter 30. This has rectangular aperture 31 and cylindrical lens 35.

The advantage of this arrangement is that the light beam offers no obstruction to the horizontally movable print element 20.
