Description

Die Erfindung betrifft eine Maschine zum fortlaufenden' Photokopieren unter Verwendung eines Kopierpapierbandes verschiedener Breiten, das über die Kopierunterlage bewegt wird.The invention relates to a machine for continuous photocopying using a copy paper tape of different widths over the copy base is moved.

Die Erfindung besteht darin,-daß die Kopiervorlage und das Kopierpapier mittels einer Transportdecke über eine gewölbte Scheibe gezogen wird, welche durch ein abhlendbares Leuchtrohr angestrahlt wird.The invention consists in -that the master copy and the copy paper is pulled by means of a transport cover over a curved disc, which through a light tube that can be illuminated is illuminated.

Die richtige Belichtung wird durch die Abblendung erreicht, wodurch eine Geschwindigkeitsregelung der Transportdecke, wie sie bei bisher bekannten Maschinen besteht, gespart wird. Durch die konstante Transportgeschwindigkeit über ein in der ganzen Arbeitsbreite gleichmäßig -strahlendes Leuchtrohr (Neonlicht) ist eine iooo/oige Ausleuchtung garantiert.Correct exposure is achieved by stopping down, which a speed control of the transport ceiling, as in previously known machines exists, is saved. Due to the constant transport speed via an in A fluorescent tube (neon light) that shines evenly across the entire working width is one 100% illumination guaranteed.

In der Zeichnung ist ein Ausführungsbeispiel .der Photokopiermaschine dargestellt, und zwar stellt die Abbildung eine Seitenansicht im Schnitt dar.In the drawing is an embodiment of the photocopying machine shown, namely the figure represents a side view in section.

Der Motor i treibt mit seinem Zahnrad 2 das Zahnrad 3 der Antriebswalze 4 an; die Antriebswalze 4 treibt wiederum die Transportdecke 5, die über die Spannwalze 6 geführt und über die gewölbte Scheibe 7 zur Antriebswalze ¢ zurückgeführt wird.The motor i drives the gear 3 of the drive roller with its gear 2 4 on; the drive roller 4 in turn drives the transport cover 5, which is over the tension roller 6 is guided and returned to the drive roller ¢ via the curved disk 7.

Die Lagerungen an beiden Enden der Spannwalze 6 sind durch je eine Spannvorrichtung 8 so verstellbar, daß damit die Transportdecke 5 gespannt und ihr Lauf über die beiden Walzen 4 und 6 ausgemittelt wird. Die gewölbte Scheibe 7 wird vom Belichtungskasten 9 gehalten, an dem sich außerdem ein Rollenkasten io zur Aufnahme von Kopierpapier befindet. Im Belichtungskasten 9 ist ein Leuchtrohr i i (Neonlicht usw.) auf einem feststehenden, halbrund zur Segmentscheibe 7 hin geöffneten Abblendrohr 12 befestigt. Über dem Abblendrohr 12 ist das ebenfalls halbrunde Abblendrohr 13 drehbar. Die beiden Abblendrohre 12 und 13 sind an den beiden äußeren Enden rund geschlossen, damit sie sich gegenseitig führen. An dem drehbaren Abblendrohr 13 ist ein Zeiger befestigt, der durch einen abgeblendeten Schlitz im Belichtungskasten 9 geführt wird und an einer Skala die genaue Belichtungsstärke anzeigt.The bearings at both ends of the tension roller 6 are each through one Clamping device 8 adjustable so that the transport ceiling 5 is stretched and you Run over the two rollers 4 and 6 is averaged out. The domed disc 7 is held by the exposure box 9, on which there is also a roller box io for recording copy paper is located. In the exposure box 9 is a light tube i i (neon light etc.) on a fixed, semicircular to the segment disc 7 open towards the blind tube 12 attached. The shielding tube 13, which is also semicircular, is above the shielding tube 12 rotatable. The two shielding tubes 12 and 13 are round at the two outer ends closed so that they lead each other. On the rotatable shielding tube 13 A pointer is attached to it, which can be seen through a masked-out slot in the exposure box 9 and shows the exact exposure level on a scale.
