Abstract

The photocopier has the copy sheets fed through from one side to the other in a simple guide. The document is scanned by a fibre optic (7) and projected onto the process drum (6) by a penta-prism (8). The copier hinges at one end to split along the copy path so that blockages are simple to clear. The document is placed on a transparent top plate which moves over the scanning slot. No complex mirror drives are required. A toner powder developer (11) is provided by a gravity fed reservoir while a cleaning roller (22) and scraper remove excess toner. A radiant heater (18) fixes the copy. The copy sheets are taken from a magazine at one end and pass out of an exit slot at the other end.

Description

Bezeichnung: KopiergerätName: copier

Beschreibung Die Erfindung betrifft ein Kopiergerät nach dem Gattungsbegriff des Patentanspruches. Es ist bekannt, daß ein solches Gerät besonders kleingehalten werden kann, so daß es sich als hochwertiges Tischkopiergerät eignet.Description The invention relates to a copier according to the generic term of the claim. It is known that such a device is kept particularly small can be, so that it is suitable as a high quality desktop copier.

Bei den bekannten Geräten dieser Art wird das Kopierpapier von der einen Seite her an den Prozeßzylinder herangeführt und auf derselben Seite nach der Entwicklung des Puderbildes wieder herausgeführt. Hierbei tritt der Nachteil auf, daß dann, wenn sich das Papier im Gerät verklemmt oder aus einem anderen Grunde steckenbleibt, nur sehr schwer an das Papier heranzukommen ist, da die Papierbahn versteckt liegt. Oblicherweise müssen bei diesem Gerät verschiedene Prozeßclelllente nacheinander gelöst und weggeschwenkt werden. In the known devices of this type, the copy paper of the one side brought up to the process cylinder and afterwards on the same side the development of the powder image brought out again. This has the disadvantage on that if the paper is jammed in the machine or for some other reason gets stuck, the paper is very difficult to get because of the paper web is hidden. Usually, various process elements must be used in this device be released and swiveled away one after the other.

Aufgabe der erfindung ist es, ein Gerät der beschriebenen Art anzugeben, bei dem man leicht an ein steckengebliebenes Kopierpapier herankommt. The object of the invention is to provide a device of the type described, where you can easily get hold of a stuck copy paper.

Diese Aufgabe wird durch das kennzeichnende Merkmal des Patentanspruches gelöst. This task is achieved by the characterizing feature of the patent claim solved.

Bei dieser Auslri ldullg ist nur notwendig, das Oberteil hochzuklappcn, und die Papierbahn liegt dann auf ihrer ganzen Länge im (erst Frei. With this opening it is only necessary to fold up the upper part, and the paper web is then in its entire length in the (first free.

Auf der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt, und zwar zeigen: Fig. 1 die perspektivische Darstellung des Gerätes; Fig. 2 einen Schnitt durch das Gerät; Fig. 3 das Gerät im aufgeklappten Zustand. In the drawing, an embodiment of the invention is shown, namely show: 1 shows the perspective view of the device; 2 shows a section through the device; 3 shows the device in the unfolded state.

Die Vorlage wird auf eine verschiebbare Glasplatte 1 gelegt, die über einen Belichtungsspalt 2 fahrbar ist, der von einer Lichtquelle 3 mit zugeordnetem Reflektor 4 und einem Spiegel 5 ausgeleuchtet wird. Der Lichtspalt 2 ist seitlich oberhalb des Prozeßzylinders 6 angeordnet, ebenso eine Faseroptik 7, welche aus Gradientenfasern gebildet ist. Sie projiziert ein seitenverkehrtes Bild der Vorlage mit Hilfe eines nachgeschalteten Pentaprismas 8 seitlich auf den'Prozeßzylinder. Der Zylinder trägt eine fotoleitende Schicht und dreht sich synchron zur Verschiebung des Wagens. Das auf dem Zylinder erzeugte latente elektrostatische Bild wird mit einer Entwicklerwalze 10, die aus einem Vorratsbehälter 11 Toner 12 entnimmt, entwickelt. The template is placed on a sliding glass plate 1, the can be moved over an exposure gap 2, which is associated with a light source 3 Reflector 4 and a mirror 5 is illuminated. The light gap 2 is on the side Arranged above the process cylinder 6, as well as a fiber optic 7, which from Gradient fibers is formed. It projects a reversed image of the original with the help of a downstream penta prism 8 on the side of the process cylinder. The cylinder carries a photoconductive layer and rotates synchronously with the displacement of the carriage. The electrostatic latent image created on the cylinder is with a developer roller 10, which takes toner 12 from a storage container 11, is developed.

Einer Kassette 13 wird ein Kopierpapier 14 entnommen und mit Hilfe von Transportwalzen 15 sowie einer Papierführung 16 an den Zylinder gebracht. Mit Hilfe einer Obertragungskorona 17 wird das Puderbild auf das Papier übertragen. Walzen 27 leiten das Papier zu einer Fixierstation 18, und Walzen 19 führen die so entstandene Kopie mit dem Bild nach oben in Richtung des Pfeiles 20 aus dem Gerät heraus.A cassette 13, a copy paper 14 is taken out and with the help brought by transport rollers 15 and a paper guide 16 to the cylinder. With With the aid of a transfer corona 17, the powder image is transferred to the paper. Rollers 27 guide the paper to a fuser 18, and rollers 19 guide the paper The resulting copy with the image facing up in the direction of arrow 20 from the device out.

Zwischen dem Spiegel 5 und dem Prozeßzylinder 6 ist die Aufladekorona 21 vorgesehen. Between the mirror 5 and the process cylinder 6 is the charging corona 21 provided.

Zwischen den Transportwalzen 27 und der Aufladekorona 21 ist eine Walzenbürste 22 vorgesehen, welche die Prozeßtrommel von noch anhaftendem Toner reinigt, der nicht mit übertragen wurde.Between the transport rollers 27 and the charging corona 21 is one Roller brush 22 is provided, which the process drum of still adhering toner cleans that was not transferred.

Wie aus Fig. 3 zu erkennen ist, ist das Oberteil 26 des Gerätes mit Hilfe eines Scharnieres 25 aufklappbar. As can be seen from Fig. 3, the upper part 26 of the device is with Can be opened with the aid of a hinge 25.

Im Oberteil 26 sind die Fixiereinrichtung 18, der Prozeßzylinder 6, die Walzenbürste 22, die Aufladekorona 21, die Abbildungs- und Beleuchtungsoptik 7, 8 sowie 3, 4, 5, ferner die Entwicklerwalze 10, der Vorratsbehälter 11 und der Wagen 1 angeordnet. Außerdem befindet sich in diesem Teil noch eine Walze 31, mit deren Hilfe die einzelnen Kopierpapierblätter der Kassette 13 entnommen werden.In the upper part 26 are the fixing device 18, the process cylinder 6, the roller brush 22, the charging corona 21, the imaging and lighting optics 7, 8 and 3, 4, 5, also the developer roller 10, the storage container 11 and the Car 1 arranged. In addition, there is also a roller 31 in this part the aid of which the individual sheets of copy paper are removed from the cassette 13.

Man erkennt, daß dann, wenn das Oberteil 26 hochgeklappt ist, die Papierbahn vollkommen offenliegt, d.h. It can be seen that when the upper part 26 is folded up, the Paper web is completely exposed, i.e.

im unteren Geräteteil sind verblieben: die Kassette 13 mit den Papierblättern, die Papierführung 16, die untere Transportwalze 15, ferner der Trennwalzenmechanismus 27 sowie eine weitere Papierführung 30 und die untere Transportwalze 19. Man kommt bei hochgeklapptem Deckel unmittelbar an das Papier heran. Die Linie 32 bezeichnet die Unterkante des Oberteiles bzw. die Oberkante des Unterteiles, auf der das Oberteil 26 im geschlossenen Zustand aufliegt.in the lower part of the device are left: the cassette 13 with the paper sheets, the paper guide 16, the lower feed roller 15, and the separation roller mechanism 27 as well as another paper guide 30 and the lower transport roller 19. You come when the lid is up, you can get close to the paper. The line 32 denotes the lower edge of the upper part or the upper edge of the lower part on which the upper part 26 rests in the closed state.
