Description

Lichtpausbelichtungs- und -entwicklungsvorrichtung mit einem zwischen dem Belichtungsteil und dem Entwicklungsteil in der Bewegungsbahn des Lichtpausmaterials und der Kopiervorlage angeordneten Schwenkkörper Die Erfindung bezieht sich auf eine Lichtpausbelichtungs- und -entwicklungsvorrichtung mit einem zwischen -dem Belichtungsteil und dem Entwicklungsteil in der Bewegungsbahn des Lichtpausmateriäls und der Kopiervorlage ange qr,dn,eten Schwenkkörper, der durch das nach Beendigung der Belichtung freikommende Lichtpausmaterial in eine Lage übergeführt wird, in der er . mit einer Schneide an dem Lichtpausmaterial entlang streicht, so daß die nacheilende Kopiervorlage von .dem Lichtpausmaterial abgehoben und von diesem abgelenkt wird, und der von selbst wieder in seine Ausgangsstellung zurückkehrt, wenn das Lichtpausmaterial vorbeigelaufen ist. Bei den bekannten Vorrichtungen dieser Art ist die Wirkung des Schwenkkörpers recht unsicher. Die Ursache dafür liegt im wesentlichen darin, daß die Schneide des Schwenkkörpers, welche das Lichtpausmaterial abstreicht, nur ganz locker auf dem Lichtpauspapier aufliegt.Blueprint exposure and development device with an intermediate the exposure part and the development part in the path of movement of the blueprint material and the master arranged swivel body The invention relates to a blueprint exposure and development device with a between -dem Exposure part and the development part in the path of movement of the blueprint material and the master copy is qr, dn, eten swivel body, which is caused by the after completion the light tracing material released after the exposure is transferred into a layer in the he. strokes along the blueprint material with a cutting edge so that the trailing original is lifted from the blueprint material and deflected by it and which will automatically return to its original position if that Blueprint material has passed. In the known devices of this type the effect of the swivel body is quite uncertain. The reason for this lies essentially in that the cutting edge of the swivel body, which wipes off the blueprint material, just rests loosely on the tracing paper.

Um, diesen Nachteil zu vermeiden, ist nach der Erfindung hinter dem Schwenkkörper eine Vorrichtung angebracht, die das Lichtpausm.aterial über den Schwenkkörper hinw 'i,eht. Auf diese Weise wird die abstreiegz; chende Schneide des Schwenkkörpers sehr fest gegen das Lichtpauspapier gedrückt. Es wird daher eine völlig sichere Abstreichwirkung erzielt.In order to avoid this disadvantage, according to the invention, a device is attached behind the swivel body, which points the light pause material over the swivel body. In this way, the descending; The corresponding cutting edge of the swivel body is pressed very firmly against the tracing paper. A completely safe scraping effect is therefore achieved.

In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes in Fig. i im Ouerschnitt und in Fig. 2 in der Aufsicht dargestellt.The drawing shows an exemplary embodiment of the subject matter of the invention shown in Fig. i in cross section and in Fig. 2 in plan view.

Die gebogene Glasplatte i bildet einen Teil der Belichtungsvorrichtung, die in bekannter Weise ausgeführt und nicht weiter veranschaulicht ist. Über diese Platte i läuft ein endloses Tuch :2. Das über eine Rolle 3 zurückkehrende Tuch ist mit q. bezeichnet. Zwischen dem Tuch und der Glasplatte befinden sich das lichtempfindliche Papier 5 und die Kopiervorlage 6. Beide werden .durch das umlaufende Tuch über die Glasplatte gezogen, wobei das Papier durch eine nicht dargestellte Lichtquelle belichtet wird. Papier und Kopiervorlage werden derart zwischen Glasplatte und Tuch gelegt, daß das Papier um einige Zentimeter in bezug auf die Kopiervorlage vorragt.The curved glass plate i forms part of the exposure device, which are carried out in a known manner and not illustrated further is. An endless cloth runs over this plate i: 2. The one returning via a roll 3 Cloth is marked with q. designated. This is between the cloth and the glass plate light-sensitive paper 5 and the master copy 6. Both are .by the rotating Cloth pulled over the glass plate, the paper being replaced by a not shown Light source is exposed. Paper and master copy are placed between the glass plate and cloth put that the paper a few centimeters with respect to the copy template protrudes.

In der Bewegungsbahn des nach Verlassen der Belichtungsvorrichtung freikommenden Lichtpauspapiers ist ein um Zapfen io drehbarer Schwenkkörper 9 angeordnet. Dieser Schwenkkörper ist mit Aussparungen für die Rollen 7, welche vorzugsweise einen Gummibelag aufweisen, versehen. Diese Rollen 7 bilden zusammen mit einem festen Tisch ,9 eine Ziehvorrichtung.In the path of movement after leaving the exposure device A swivel body 9 rotatable about pegs is arranged on the light tracing paper coming free. This swivel body is provided with recesses for the rollers 7, which are preferably have a rubber covering provided. These rollers 7 form together with a fixed Table, 9 a pulling device.

Im freien Zustand nimmt der Schwenkkörper die mit gestrichelten Linien gezeichnete Lage 9` ein. Er wird aber durch das Papier, nachdem letzteres durch die Rollen 7 erfaßt worden ist, in die Lage 9 übergeführt, in der seine .schneidenförmige Rückseite an dem Papier entlang streicht. Da auf das Panier, welches zwischen die Rollen 7 und den Tisch 8 gelangt, ein Zug ausgeübt wird, wird die schneldenförmige Rückseite des Schwenkkörpers 9 fest an das Lichtpauspapier angepreßt, so daß die nacheilende Kopiervorlage sicher von dem Papier abgehoben und unter dem Schwenkkörper hindurch abgeführt wird. Das Lichtpauspapier wird zwischen den Rollen 7 und dem Tisch 8 hindurch der Enttvicklungsvorrichtung zugeführt.In the free state, the swivel body takes the dashed lines Drawn position 9`. But it gets through the paper after the latter through the rollers 7 has been detected, transferred to the position 9, in which his Stroke the back along the paper. Since on the banner, which is between the Rolls 7 and the table 8 arrives, a train is exerted, the snake-shaped Back of the swivel body 9 firmly pressed against the blueprint paper, so that the trailing copy is safely lifted from the paper and under the swivel body is discharged through. The blueprint paper is between the rollers 7 and the Table 8 fed through the development device.
