Patentiert im Deutschen Reiche vom 6. August 1905 ab.Patented in the German Empire on August 6, 1905.

Vorliegende Erfindung bezieht sich auf eine Einrichtung zur Exponierung solcher photographischer Platten und Films, welche in lichtdichten , auf den Platten verschiebbaren Hüllen stecken. Die Erfindung bezweckt eine derartige Ausgestaltung der Kassette, daß die Platte mit ihren Hüllen so eingesetzt werden kann, daß die Hüllenenden durch die gegenüberliegenden lichtdichten Schlitze derThe present invention relates to an apparatus for exposing such photographic ones Plates and films, which are in light-tight, sliding on the plates Stuck sleeves. The invention aims at such a design of the cassette, that the plate can be used with their shells so that the shell ends through the opposed light-tight slots of the

ίο Kassette hindurchragen und daß sie seitlich von den lichtdichten Schlitzen oder von einem derselben durch eine Anschlagsleiste eingeklemmt werden, die entweder über die ganze Kassettenbreite herüberragt oder nur über einen Teil derselben, und die dem in der Hülle steckenden Schichtträger als Anschlag dient, wenn ein der betreffenden Anschlagsleiste benachbartes,, aus· der Kassette herausragendes Hüllenende erfaßt und hieran die Hülle herausgezogen wird. Bei dieser Anordnung bedarf es keines besonderen Organs, um die Hülle des lichtempfindlichen Schichtträgers im Innern der Kassette zu öffnen, da die auf beiden Seiten aus der Kassette durch die gegenüberliegenden lichtdichten Schlitze herausragenden Hüllenenden ohne weiteres durch Abreißen eines geschlossenen Hüllenendes die Öffnung der Hüllen ermöglichen. ίο the cassette protrude and that it is on the side clamped by the light-tight slots or one of them by a stop bar that protrudes either over the entire width of the cassette or only over part of the same, and the one in the The layer carrier inserted into the envelope serves as a stop when a stop bar adjacent to the relevant stop bar protrudes from the cassette Cover end grasped and here the cover is pulled out. With this arrangement there is no need for a special organ around the shell of the photosensitive layer support to open inside the cassette, as the opposed light-tight on both sides of the cassette Slits protruding sheath ends easily by tearing off a closed one Envelope ends allow the envelopes to be opened.

Es bedarf auch keiner einstellbaren Festhaltevorrichtung für den Schichtträger, welche die lichtdichte Hülle desselben beim Herausziehen aus der Kassette zerschneidet. Die neue Kassetteneinrichtung bietet daher eine leichte Handhabung und zugleich eine besonders einfache Konstruktion.There is also no need for an adjustable retaining device for the layer support, which cuts the light-tight envelope of the same when pulling it out of the cassette. the new cassette device therefore offers easy handling and at the same time a special one simple construction.

Die den Gegenstand der Erfindung bildende Kassette und eine Schichtträgerpackung, welche in Verbindung mit der Kassette zur Anwendung gelangen kann, sind auf der beiliegenden Zeichnung dargestellt, und zwar zeigtThe cassette forming the subject of the invention and a support package which in connection with the cassette can be used, are on the enclosed Drawing shown, namely shows

In der Zeichnung ist der Hinterraum der Kassette mit α bezeichnet. Derselbe ist zur Aufnahme der belichteten Platten oder Films b bestimmt und wird gegen den Belichtungsraum durch den Schieber c in bekannter Weise abgeschlossen. Der Schieber c ist in seinen Nuten lose geführt und steht unter dem Einfluß von seitlich angebrachten Federn d. Durch die nachgiebige Lagerung des Schiebers c wird es möglich, dieselbe Kassette für Platten und für Films (auf der Zeichnung sind Films angenommen) zu benutzen. Der Expositionsraum wird nach außen hin durch den Deckelrahmen e begrenzt. Eine Leiste f ist an den seitlichen Rahmstücken der Kassette befestigt. Der Deckelrahmen ist mit einer Leiste g ausge-In the drawing, the rear space of the cassette is denoted by α. The same is intended for receiving the exposed plates or film b and is closed off from the exposure space by the slide c in a known manner. The slide c is loosely guided in its grooves and is under the influence of laterally attached springs d. The flexible mounting of the slide c makes it possible to use the same cassette for plates and for film (films are assumed in the drawing). The exposure space is limited to the outside by the cover frame e. A bar f is attached to the side frame pieces of the cassette. The cover frame is provided with a strip g

Claims

which, in the closed state of the cassette, reaches with its lower edge closer to the surface of the slide c than the upper surface of the strip f. The light-tight envelope i encloses the film k. The collecting space α of the cassette is closed off by the lower locking slide /. The light-tight envelope i of the film is closed at both ends. The closed ends are folded over, as can be seen in FIG. 3, so that the position of the film in the envelope can be seen by the folding of the ends. The pack can therefore be inserted into the cassette at any time without difficulty in such a way that the edge of the film facing the strip f is not grasped by the strip g of the lid or even comes to lie above the strip f. As soon as a pack is inserted into the cassette, for which purpose the cover frame e of the cassette is opened, and an exposure is to be made, one of the ends of the pack protruding beyond the cassette, which is located on the strip, becomes after closing the cassette cover e f located opposite side of the cassette, severed to open the light-tight envelope. The other end of the sleeve is then pulled. Here, the lower edge of the strip g forms a stop for the edge of the film k, so that the film cannot pass through the cassette slot, while the light-tight envelope can be pulled out of the cassette on the winding path shown in the drawing. Once the sleeve is peeled from the film, the film can be exposed. After exposure, the film is conveyed into the collecting space α through the opening of the slide c. As soon as the latter contains a sufficient amount of film, it is opened by pulling out the slide / and the exposed films b are removed. It is readily apparent that each and every exposed film can also be removed from the cassette. In order to hold back the films with certainty in the exposure space despite their small thickness, they can be reinforced at the end with which they are supported against the ledge g or a similar edge of the cassette. Such a reinforcement is indicated in the drawing in FIGS. 1 and 2 in the form of a narrow bar ni. From the description of the mode of operation it is evident that the device can be used for both films and plates. The device is designed for the use of packs with only one plate or one film. Instead of a single envelope, closed on both sides, it is of course also possible to use two envelopes opening on opposite sides, although this would only make the manufacture of the pack more expensive. In this case, one case would have to be pulled out of the cassette to one side and the other to the other side. The essential feature of the present invention would also be in this case that that envelope which directly encloses the film or the plate is pulled out of the cassette to the same side on which the ^ film or. the plate is held back by a stop against the edge of the cassette slot, so that special means of holding the film, for example on the opposite side, are not required. Patent claims: "

1. Cassette with light-tight slots located on opposite sides, which allow a layer carrier pack inserted into the cassette to pass through, characterized in that next to the light-tight slots or next to one of them on one side of the cassette space one or more over the entire width of the cassette or part thereof extending stop strips (g) are provided which, in conjunction with the adjacent light-tight slot, form a tortuous path for the flexible shell of the layer support, into which the relatively rigid layer support cannot enter.

2. Cassette according to claim 1, characterized in that the one slot wall is formed by a bar (f) which protrudes from the plane of the support surface (c) for the layer support and which is on one or both sides of counter strips (g) on the opposite slit wall is included.

3. Cassette according to claim 2, characterized in that the stop strips (g), which are associated with the strip (f) protruding from the plane of the support surface for the layer support, as counter strips, are arranged on a removable or hinged cover (e) .
