Abstract

The device is designed to align typewriter sheets. The unit ensures easy location of the printed paper for correction by locating that spot directly in the printing zone of the type head where the top ends (4/4a) of the ribbon controlling fork (1) carry aligning strips (5/6). The upper surfaces of the latter are aligned with locating markings (9) of the printing line rule (10), and the strips feature upward directed ribs (11/12) which are narrow for limiting the view of the correction spot.

¥ ie from DIK 21: β / ϊϊο vernier 1953, sheet I ₅ pages 1 big 8 nad BJ * 5, it is common practice to use a sheet of paper odsr a 2?

Object of the invention: it is to create a score indicator, the targeted alignment of the paper sheet ait his? .. B » Correction adjustment made possible directly in the area of the Drue side of the type carrier

This task is solved by the in the label of the Pa tentanspruchs 1 specified means and their arrangement.

In dex ^j e drawing is, n embodiment 'illustrated the ärfindimg described in more detail below "

In the drawing, a ribbon fork 1 is shown _{¥ which can be lifted into} a working position from a lower rest position (as shown), in which it releases the printing field of a type carrier (not shown) on the platen (platen 2 with sheet of paper 3) for inspection. At the upper ends 4 and 4a of the ribbon fork 1 horizontally arranged strips are provided, this as straightening strips 5 and 6 with their upper surfaces 7 and 8 with the alignment marks 9 of a line straightener 10 then lie on a common straight line when the ribbon fork is in their lower rest position «,

At the facing ends of the straightening strips 5 and 6 of the ribbon fork 1, an upwardly projecting Eichtsteg 11 or 12 is formed, which run parallel and perpendicular to each other, and which are so narrow that you can see the 7-u both sides ev1 ;; l _e already existing characters or table columns on the sheet of paper 3 for an operator to be crossed out, is well guaranteed. The length of the straightening webs 5 and is dimensioned in such a way that the printing field 13 of a character type is enclosed laterally for at least a partial area.

The straightening webs 11 and 12 have such a distance from one another which, in the case of lever type writers, corresponds at least to the width of the type blocks provided with the character types, whereby a passage opening 14 is retained for this.

It is of course _possible%, the ink ribbon fork and form such that none are present upwardly projecting guide webs, sized function (middle indicator) is then taken over by the end faces of the Richt3eLsten to gegenüberliegendexi. Here, however, there would then be no immediate lateral enclosure of the pressure field by the straightening webs; the middle adjustment of the sheet of paper could then be made according to the upper edges, which are formed by the straightening strips and the passage opening, which are then directly opposite the imaginary base of the diagonal from the two sides *

In a further structural configuration of the center indicator according to the invention, only one straightening bar can also be used, which can then even be arranged exactly in the middle of the printing field, and which is preferably used in such printing units arrives, in which the ribbon stroke between the rest position and the working position can be trained so large that in the area of the Center indicator on the passage opening for the type carrier can be dispensed with »
