Description
zeichen »g, j, ρ, q,y« weist der Transportschlitten 7 zwei oberhalb der hinteren FührungsachseS angeordnete Lagerungen 10, 11 auf, zwischen denen parallel zur Schreibrichtung und zu den Führungsachsen 8,9 eine weitere Führungsachse 12 befestigt und auf der der Rasterdruckkopf schwenkbar gelagert ist. Am Boden 13 des Rasterdruckkopfes ist weiter eine U-förmig ausgebildete Führungsschiene 14 angeordnet, auf deren Innenschenkelfläche 15 sich die Anlagefläche 16 des Transportschlittens 7 zusätzlich abstützt, wobei der Rasterdruckkopf unter dem Einfluß beispielsweise einer Druckfeder 17 nach oben, d. h. in der Schreibgrundstellung gehalten wird. Auf diese Weise, wird ein Luftspalt 18 zwischen dem Rasterdruckkopf 2 und dem Transportschlitten 7 gebildet. Des weiteren ist eine Ankerplatte 19 am Boden 13 des Rasterdruckkopfes angeordnet, die einem am Transportschlitten 7 befestigten Elektromagneten 20 gegenübersteht. Es sollen nun beispielsweise die Buchstaben W, e, g eines Druckbildes nach F i g. 3 geschrieben werden. Hiernach besteht der BuchstabeW und e aus den 5x7 Rasterpunkten, die keine Absenkung des Schreibkopfes benötigen, während der Buchstabe g mit der Unterlänge im gleichen 5 χ 7 Raster nur nach Absenken des Rasterdruckkopfes 2 um das Absenkmoß 22 geschrieben werden kann. Hierzu wird über ein von einer entsprechenden Logik kommendes Signal der Elektromagnet 20 betätigt, und in Verbindung mit der am Rasterdruckkopf 2The transport slide 7 shows characters "g, j, ρ, q, y" two arranged above the rear guide axis S. Bearings 10, 11, between which parallel to the writing direction and to the guide axes 8, 9 a further guide shaft 12 is attached and pivotably mounted on the raster print head is. On the bottom 13 of the raster print head there is also a U-shaped guide rail 14 arranged, on the inner leg surface 15, the contact surface 16 of the transport carriage 7 is also supported, the raster print head under the influence of, for example, a compression spring 17 after above, d. H. is held in the basic writing position. In this way, there is an air gap 18 between the Raster print head 2 and the transport carriage 7 are formed. Furthermore, an anchor plate 19 is on the ground 13 of the raster print head arranged, the one attached to the transport carriage 7 electromagnet 20 faces. For example, the letters W, e, g of a print image according to FIG. 3 to be written. According to this, the letters W and e consist of the 5x7 grid points that do not have any subsidence of the write head, while the letter g with the descender in the same 5 χ 7 Raster can only be written after lowering the raster print head 2 around the lowering moss 22. For this purpose, the electromagnet 20 is actuated via a signal coming from a corresponding logic, and in connection with the one on the raster print head 2
s angeordneten Ankerplatte 19 wird der Schreibrüssel des Ankerdruckkopfes um den Luftspak 18 abgesenkt und der volle Buchstabe g zum Abdruck gebracht. Nach der Kontaktunterbrechung wird zwangläufig über die zwischen Transportschlitten 7s arranged anchor plate 19, the writing trunk of the anchor pressure head is lowered by the air parcel 18 and the full letter g printed. After the contact is broken necessarily via the between the transport carriage 7
ίο und Rasterdruckkopf 2 angebrachte Druckfeder 17 der Rasterdruckkopf wieder in die Nullstellung zurückgeführt. ίο and raster print head 2 attached pressure spring 17 the raster print head is returned to the zero position.
Nach der F i g. A ist die Zeit-Weg-Funktion des Rasterdruckkopfes 2 an der Schreibstelle aufgezeigt, aus dem die Absenkzeit 23 sowie die Rückführzeit 24 erläuternd dargestellt ist.According to FIG. A shows the time-distance function of the raster print head 2 at the writing point, from which the lowering time 23 and the return time 24 are shown in an explanatory manner.
Die Anwendung der Groß- und Kleinschreibung mit Unterlänge gemäß Erfindungsvorschlag ist nicht nur allein auf Mosaik-Druckwerke beschränkt, son-The use of upper and lower case with descender according to the proposed invention is not only limited to mosaic printing works, but
ao dem kann auch ohne wei'rres für Thermodruckwerke, Tintenschreiber, RMP-Schreiber usw. verwendet werden.ao dem can also be used for thermal printing units, Ink pens, RMP pens, etc. can be used.
Hierbei ist es ohne größere konstruktive Änderung möglich, das Rasterdruckwerk auch geradlinig abzusenken. Here it is possible, without major structural changes, to lower the raster printing unit in a straight line.
