Abstract

1,191,086. Typewriters. GERATEWERK KARL-MARX-STADT. 11 March, 1969, No. 12728/69. Heading B6F. In a tabulating mechanism, interference of a light beam by tabulator stops 4 is detected by a light receiver 9 to control tabulation. As shown, a light beam from a source 6 is deflected by two prisms 2 and 3 movable with the type head or carriage device of a typewriter before impinging on a light receiver 9 such as a photodiode. Tabulator stops 4 (Fig. 2) mounted in a fixed tabulator bar 5 are selectively slid into a light obstructing plane normal to the light beam path between the two prisms. Depressing the tabulator key releases the type head or carriage device until the photo-diode detects the presence of a tabulator stop 4.
