Refinement of the grid in line direction slows down the writing teraoo.

The object of the invention is to improve the printed visualization while avoiding the disadvantages mentioned. A first solution of the invention is characterized in that the line feed steps are shorter than the width of the writing point of a printing tip and that a is activated again at the next but one line prefix at the earliest. After this. Solution, the grid is refined in the direction of the lines and that dopt> elt so fine. First of all, as expected, this results in a considerable improvement in the printed lettering. It has been shown, however, that this improvement can also be achieved if one does not utilize all grid positions and dispenses with occupying two sensor positions that are adjacent in line direction. The invention makes use of this fact. The result is that "at the very least, a single writing wire is operated just as quickly in succession: are" feet, as with the unauthorized buster, and this has the consequence that, assuming the same conditions, the refined grid can be written at the same writing speed, " like the coarse grid, because the friction speed is limited by the repetition frequency with which the individual wires can be maximally activated. '. . .

applied "to earth". The second solution refined the grid by additionally provided writing wires. This is how to expect »an additional effort required, but this additional Writing wires lie with their pressure tips in the positions in which they are used to improve the writing. are uncomplicated. Experience has shown that you can already do it one or two additional writing wires at skillfully chosen Positions a very considerable improvement in the lettering of the · ■ printed letter can achieve. This second solution of the invention thus achieves a significant improvement in the font ^ that is almost as good as that made by a doubly refined one Grid achievable by just one or two additional writing lines «

These control signals indicate which wires or which Torisohubaggregate are activated in the individual printing phee εοΐΐβη in order to print out the mentioned book deeds. In a known device of the type described here, the individual letters are written out by means of dots which are located at the cross points of an orthogonal network of five columns and seven lines, these positions being so spaced that adjacent sparks cannot overlap orthogonal Hetz is shown in Fig. 2 for the first five letters drawn there * From Fig. 2 it can be seen that there are hardly any difficulties with this notation if the letters, such as "X" and "E *" consist only of straight lines These letters are also clearly written out · Capital letters, on the other hand, with diagonal lines or curved lines, such as the "B * and ¹¹ O" are written out less well, for some letters »for example the letters V» A, Y, W and X suffers with this notation the legibility, as can be seen from Pig. 2, quite considerably «*

column is located. Intermediate columns denote those grid columns which, according to FIG. 3, are in addition to FIG. 2 are inserted into the caster. In addition, a wire is only used in activated in the intermediate column, if it was not activated in the main column immediately in front of it. Am and the same Wire - including the intermediate columns - is only activated as soon as a main column or an intermediate column is crossed over. This rule is necessary so that between two Actuations of one and the same wire provide sufficient recovery time and not because of the additionally introduced in-between Pal ten must slow down the overall printing process accordingly. In other words, “this provision allows the narrower grid to print out according to Fig. 3 with the same feed speed in the line direction, as the grid of Fig. 2 otherwise the same Assuming circumstances.

In the grid on which the invention is based, diagonal lines are printed out with dots which overlap in the direction of the lines. In the Pig grid, such diagonals have. 3 an incline of 30 degrees with respect to the column direction. With such diagonals, the expression of critical letters can be considerably improved, never inclining Fig. 3 compared to Fig. 2 ₍ (compare in particular the letters 0, V, A, Y and X.) In this way, one is also able to the diagonals of the letters X, Y and V to be drawn very well, this is shown most clearly with the letter X.There the dots 30 and 31 are printed out at the original ftasterpositlonen * while the dots 32 and 34 are printed out on a double column * The Points 31 to 34 overlap in line alignment and so very clearly form the desired diagonal drill pull.

as explained in the text of FIG. 3. The improvement in pressure let clearly recognizable by comparing FIGS. 4 and 5. The digit 2 for example is in the area of the points 35,3 * and 37, the overlap in line direction, rounded. The number 7 shows a straight diagonal formed by the fact that the individual Alternate dots on an original grid column and an in-between column lie »The zero is after Pig. 5 actually oval and no longer "square" as shown in Pig. 4 · 6 has an actually diagonal line of overlapping points and is therefore much easier to read than the 6 out. 4. It is thus evident that by alone the insertion of the column columns, the legibility of the capital letters and the digits can be significantly improved.

In Fig. 6 and 7 are provided to explain the arrangement of the Wires the print positions of the intended wires are drawn as circles » The picture shown in Figures £ and 7 would change thus result as a print image if you put all the wires in at the same time activated in a printing phase - in the example embodiment according to FIG. 6 are all wires (adjusted to their Druckposltioiien) in one Column Arranged one on top of the other * The top seven wires are sufficient for printing uppercase letters, while lowercase letters are sufficient for printing additionally the two below the dashed line 56 provided wires 39 and 40 can be used. The additional provided wires 39 and 40 are advantageous in connection with those lowercase letters "dl" such as the letter ρ and 4 protrude below the writing line · The letters g, <j, p, q and y are the only ones to protrude below the rubbing line in the publication considered here. With the exception of these five letters So all other letters with the seven upper wires become written, while for the five letters mentioned also the the two particles of wires 39 and 40 are drawn into them It is possible with one and the same print head large and small
