film tapes on spools are no longer used, but a flat photographic material that supports the Has the form of an annular disc which is arranged on the outer edge of a central support disc. The usage Such film disks have the particular advantage that the camera is kept extremely thin can be and, for example, only has the format of a paperback.

Develop around the already exposed film discs and to be able to treat, special devices have been created in which each has a central bore Film disks are lined up on spindles in the dark. The treatment of these film disks takes place here in a known manner in a series of containers arranged one behind the other, in each of which there are different Treatment fluids are located. Here are the The spindles are each hung in the treatment tank, set in rotation and after the intended treatment times have elapsed implemented in the following containers.

However, it often is with such a treatment device it is disadvantageous that a large number of film disks have to be lined up on a spindle before such a fully loaded one Spindle can be supplied to the actual treatment.

- It - 7.7.1982

Another disadvantage is that the film discs can only be removed from their in a darkroom light-tight protective cover can be removed and strung on the spindle. This removal of the film discs as well as the plugging of the same onto the spindle does not always take place at the location of the treatment device, but in a special darkroom. To now the spindle equipped with these film disks to the treatment and In order to be able to supply the developing device, special light-tight containers are required in which the film disks are placed loaded spindles and are to be transported in these to the developing device. So are already special mobile containers have been created through which the temporary storage and transport of a larger number of spindles equipped in this way is possible.

Upon the arrival of one or more with the film discs light-tight container containing loaded spindles in the room in which the treatment device is installed, the lighting must first be extinguished and then the equipped spindles after opening the developing device to be removed from the light-tight container and placed in the light-tight device. Has this happened and if the device is closed again in a light-tight manner, the normal lighting can be switched on again. These Type of equipping of the to be carried out in the dark

However, spindles with the film disks and their light-tight interim storage and transport is still there extremely cumbersome, not to mention that this handling is only economical if larger Amounts of such development material accumulate, why then

a

also again a development device exhibiting a corresponding performance is required.

A particular disadvantage of these devices is the fact that the exposed material to be developed is introduced in (darkness) and the development process only has to be carried out with the machine connected, which also excludes the possibility of observing the mechanical course of the development process, when these devices are often erroneously referred to as daylight devices.

The object of the present invention is now to provide a to train such development and treatment device so that the development and treatment of even small amounts the exposed Pilm discs not only economically, but can actually be done in daylight.

This object is achieved according to the invention in that the seed with at least one light-tight treatment

box, in particular a treatment cassette, which during the entire development and treatment process of receiving one or more das Serves the development material-bearing discs and the entry and exit of the respective treatment liquid has enabling light-tight openings.

In contrast to the known devices discussed above, this is not just one of the temporary storage and the transport of the containers equipped with the film disks · spindles are provided, but one Drum in which one or more film disks are introduced and until the development is completed in these remain. ' The particular advantage of using such a drum is, above all, that each individual film disc is removed from its light-tight protective cover only once in a darkroom and must then be inserted into the light-tight treatment drum without having to wait about that still a larger number of such film disks are supplied '. After inserting these film discs into the treatment drum and the closing of the same, this treatment drum with the one located in it Film disk stored in daylight for any length of time and also in daylight with the development and treatment device fed and introduced into the same. Here is

ϊ:

it then makes no difference whether the individual the film disks containing container drums immediately on the the development and treatment spindle are attached or this later, on The installation site of the development and treatment device happens. But it can also do that Development and treatment device itself actually be designed as a daylight device, which is not only a simplification and cheaper, but also allows a much simpler and more individual operation of the same. So with that he can The entire development process is visually controlled at all times and in the event of a power failure, they can be safely completed. This is particularly important in the development of the mostly non-repeatable photographic recordings.

As for this container drum itself, this is it advantageously designed as a rotationally symmetrical development cartridge, which in relation to the axis of rotation the spindle is divided transversely and has a light-tight annular slot as an inlet and outlet opening. In this case, only a single film disc has to be inserted into this cassette, so that it can be stored individually and can also be treated completely individually, which is particularly advantageous if only one relative small number of film discs has to be treated.

When using such »only small dimensions having the cassette can remove the film disc from its light-tight protective cover and insert it this film disc in the relevant cassette also in a known to si et) only small dimensions light sealed container or bag, which has two light-tight openings through which the hands and arms the person who is responsible for inserting the film disc can be firmly inserted. A special darkroom is thus unnecessary.

This cassette can consist, for example, of two cassette shells which are designed to be mirror images of one another as well as a light-tight the annular slot, however be composed of a ring inserted between the cassette shell that does not cover liquid-tight.

In a particularly expedient embodiment of this Cassette, the two cassette shells each have an annular groove, which on the one hand by an outer edge and on the other hand is limited by a central middle part, the diameter of which is approximately equal to the diameter of the The core of the supporting disk forming the film disk is incorporated into which an annular groove for receiving a sealing ring is that after inserting the film disc in the cassette in such a sealing manner on the side facing it

-8th-

-A-, 7.7.1982

this support disk rests that at least the central middle part of this support disk from that of the film disk supplied treatment liquid remains unaffected and thus no special drying of this support disk middle part is required. This liquid-tight cover of the support disk or its central part is It is particularly significant in that this middle part is not only used to center the film disc Carries annular ribs, but also has several annular grooves in which when moving the film discs from one treatment liquid to the following treatment liquid, residues of the previously used Treatment liquid remain and in the respective, next treatment liquid were carried over. This liquid-tight, during the entire development process permanent coverage of the middle parts of the pane is particularly important when drying Film discs are significant in that only the actual development material, but not the disc center parts, need to be dried. Liquid residues are thrown out of the said grooves the middle part is thus unnecessary.

Furthermore, it is useful in this context if the one located between the two cassette shells ring-shaped slit light-tight covering ring has two concentric annular ribs, both of which

7.7.1982

on the one hand protrude in the axial direction and in both Cassette scales located opposite each other Engage annular grooves, and then formed between these two annular ribs on the two cassette shells and likewise engage annular ring ribs. This cover alternately mutually protruding annular ribs the ring-shaped slot between the two cassette shells is perfectly protected against incidence of light, however, the respective treatment liquid can flow unhindered into the interior of the relevant cassette and also flow out of it again.

Rotatably around the cassette with the spindle, which is fitted onto the spindle and has a central bore to connect, these cassettes are expediently braced together in the axial direction, which for example it is to be realized that each spindle has a counter bearing serving as a stop for the cassettes as well as a Has thread for receiving a clamping nut, by means of which the cassettes lined up on the spindle are fixed be pressed against the blessing bearing.

A plurality of such cassettes carrying spindles can, for example, with their ends on both sides then in the side walls of one or more open-top treatment containers and one another opposite slots be rotatably mounted, wherein

then the distance between the respective container bottom and the support of the spindle ends is so larger than the diameter of the cassette that the spindle with the non-rotatably connected to it cassettes is freely rotatable and the individual sectors of the annular development material are successively immersed in the treatment liquid and pulled out of it again. These spindles are expediently driven by means of a gear fixedly arranged on the free end of the spindle, which meshes with a drive pinion or by means of in a chain.

If several consecutive treatments are required, thus the device advantageously has, in a manner known per se, a plurality of rows one behind the other lying, difference! treatment fluids Containers containing, which then also to confessed who fitted them with the film disks Cassette-bearing spindles converting device is assigned.

In the case of a device designed for greater performance, a drum can be used as the treatment box instead of such a cassette, the two openings of which are each covered by a cover, with the spindle carrying the film disks then being inserted into the

Both lids located central bores is stored and the edges of the drum sleeve each under exposure a light-tight annular gap which enables the treatment liquid to enter and exit engage in opposing annular grooves or annular grooves in the lids. As in this case too the spindle carrying the film disks is arranged horizontally, this spindle can also be used together with the drum by means of a transfer device from one treatment tank to the following treatment tank implemented.

In another embodiment of the invention Device, the treatment box has the shape of an open-topped box that can be closed by a lid, to use the in one or more consecutively arranged treatment tanks and in which then the the spindle carrying the film disks is rotatably mounted. This can is also expediently cylindrical formed, but whose longitudinal axis is directed vertically and whose upper opening by a detachable cover can be closed, and then both in the bottom of the can as aucti in the can lid inlet and outlet openings are arranged for the passage of the treatment liquids in the treatment vessels, Also ΐη in this case is the axis of rotation of the spindle with the directed vertically on film discs lined up in a row,
