In the following, an embodiment of the invention is illustrated with reference to FIGS. 2 explains the one Shows a detail of the scanning field constructed in the form of a matrix.

The scanning field AD is made up of an electrically non-conductive base plate GP , in the upper side of which there are milled, step-shaped grooves running parallel at regular intervals. The underside has correspondingly designed grooves which are also parallel in themselves, but perpendicular to those of the upper side. An electrically conductive wire is inserted into the deepest notch of each groove, which is glued or welded to the groove walls and thus secured against shifting and twisting. The wires lying in the grooves on the upper side of the base plate GP form the column conductors Y _n , and the wires running perpendicular thereto form the row conductors X _n . Due to the mutual penetration of the grooves regularly arranged square holes are formed, the mutual distances of which correspond to the grid size of the draft drawing and z. B. be about 5 mm. On the top of the base plate GP , a cover plate LP is fixedly arranged, on which a plurality of holes L are regularly distributed in such a way that the centers of the holes L coincide with the centers of the square openings through the base plate GP .

ίο The base plate GP can be produced as a milled part with continuous, parallel grooves regularly embedded in the top or bottom, just as easily as the cover plate LP with holes arranged in a matrix. Through the stu Fen-shaped design of each groove bottom results in a further recess into which a row conductor X _n or a column conductor Y _n can be inserted without further aids. A matrix with an exact grid is thus defined without further adjustment.

ι 2 a growing number of line connections Claim: to accommodate a narrower space. Blemen apart from such purely technological Pro scanner for converting data subscription is already preparing a draft scale a drawing in numerical input data '■ true Ätzvorlage for a circuit board Difficult Generic form for a program of automatic speeds. As shown in Fig. 1 on the basis of a block diagram, a precision drawing machine with a ma, it proves to be expedient to combine the individual line connections from a trix-shaped of row conductors and column conductors circuit diagram Z1 as well as the rasterized design drawing Z2, a so-called print drawing Scanning field on which the template for the io was to be adopted on a larger scale. This design drawing Z2 has a narrow grid, design drawing with a stylus and it is stipulated that line connections only have benes potential to each of the coordinates of the row and column or grid point that begins with a dot at grid intersections end and in their course with parts of einleiter can be laid and in which the row and column 15 zel -.en grid lines should coincide. The leader via decoding circuits with min indicates that, in addition to vertical or horizontal sufferers, a memory is connected to which only in exceptional cases an inclined output device and a reading punch unit are permitted to bind via processing sections. It has been shown that the drawing of a true-to-scale etching template is assigned to the punched card, marked by hand, for outputting the captured grid coordinates, yes, that it is also possible to use a scanning field with an electrically larger final drawing, which, according to other manunichtleitenden base plate (GP), in whose upper parts processes are produced - z. B. on the side a multitude of step-shaped ausgebildc- sticking narrow black stripes, the individual th, parallel and equally spaced line sections represent -, have great defects, the grooves is arranged, with a deeper step, 35 you are therefore one gone a different way and in each of which a column conductor (Y _n ) is created against verifying the final drawings of etching templates Z3 pushing or twisting secured, by automatic precision drawing machines PL, and their underside is a large number of so-called plotters. This means that a better result can be achieved with significantly fewer grooves formed for the row conductors (Λ ',,) on expenditure of time, which is perpendicular to the grooves in the upper side. LP), which must be permanently connected to a separate plotter program for each etching template on the top of the base plate, which contains the control commands for the and a large number of regularly arranged drawing machines. Holes (L), the respective center of which it is known, the essential data of a point with a crossing point each in the base line connection, such as start, end and kink plate perpendicular to each other groove points, from the design drawing Z 2 Hand of matches. To take grid coordinates and to list them numerically in a PR protocol. The data of this protocol are based on a KL card punch 40 punch cards transferred and are then machine readable. From the thus detected data nrbeitenden of a dater. '"" System DVA can be prepared by a Hilfspi ruramni, such that. B. on a magnetic tape M 1 The invention relates to a scanning device which stores the drawing program for the etching device for converting data from a draft 45 position and, for example, on a magnetic tape M 2 drawing in input data numerical form for a cached. Because of the in this Program of an automatic precision drawing program contained control commands records the machine with a matrix of row conductors automatic I ^; precision drawing machine PL the pure and column conductors as well as the drawing of the etching template Z3. As in Fig. 1 through The rasterized design drawing carrying the scanning field, indicated on 50 double arrows, is this final drawing to select a certain grid point with the draft drawing and the circuit diagram. the design drawing with a stylus. given potential to each one of the coordinates of this way of working has major disadvantages. The grid line and column designating the layout drawing can be laid in known conductor conductors and in which the line and column plate formats have about 24,000 intersection points. Thus, conductors can be connected via decoding circuits to at least one memory when reading the coordinates of at least one memory, which via a grid intersection and when writing the proto-output device a read-punch unit for outputting errors occurs, especially since this "listing" gives one of the recorded ones Grid coordinates on punch cards represent monotonous and tedious work. The other is assigned. 60 significant source of error is the transferring With the advancement of technology covered in the protocol PR data with the help of the card electrical components developed circuitry punch KL on punch cards. The result is always arrangements in which a growing number of again faulty etching templates Z3, and therefore components must be accommodated in ever smaller spaces, and a lot of time has to be spent. In today's form that is only through 65 to eradicate these errors. This makes the manufacturer ^: .e the use of printed circuit boards possible flawless etching templates very expensive and borrowed, but their production is also increasingly difficult and time-consuming,
and becomes more complex, because in the second phase of development, there is now an arrangement for defining it
