Film card camera

The invention relates to a film card camera with an exposure station and a development station ZV ^ developing, fixing, washing and drying of the microfilm and with a transport device for conveying the exposed camera card from the exposure station to the development station. Such cards film cameras are commonly used in the micro-film technology and therefore known.

In the known microfilm cameras, the development of the microfilm, including fixing, washing and drying, takes place in a development station in which the required treatment liquids are successively sprayed onto the microfilm and, finally, hot air is blown against it. In modern film card cameras, the entire recording cycle, i.e. the time from pressing the shutter release for exposure to leaving the fully developed and tested Ksmera card, takes about 20 seconds.

Since you have to change a template to be filmed on the: The master table often only takes a few seconds, is ^ this working speed of the microfilm camera many times over

too slow. About the expensive film card camera and the high ones To make better use of the control box, the manufacturing time for a camera card should be shortened. Also always exists more often the Ulunsch, at least from the same original create two camera cards in order to use one of them for the creation of duplicate cards and enlargements. The other is kept in the security archive. In It is very special in cases in which the original does not have to be changed between two exposures important to the development cycle of the film card camera is as short as possible.

DE-DS 3o 39 B13 made a film card camera known in which an exposed camera card is successively fed to various treatment stations on a carousel. One exposure station, one station for developing and fixing, one station for soaking and one station for drying are provided one behind the other on a circular path. Since a total of around 10 seconds is required for developing and fixing with today's technology, the carousel can be clocked one position further every 10 seconds. This is why the production of a single image takes about 50 seconds, assuming a transport time of about 2 seconds per cycle. Since the development and fusing station becomes free after 10 seconds, a second exposed camera card can then be fed to it. Two finished camera cards can therefore be created in about 60 seconds, three in 70 seconds or four camera cards in 80 seconds.

The film card camera according to DE-DS 3d 39 S13 is the same to a film card camera with only one development station, in which the microfilm to the finished negative is loaded one after the other without transporting the camera card

is much more complicated in structure and in the control. Assuming the mentioned cycle time of 2o seconds for the film card camera in use, so it follows that the film card camera according to the disclosure document for exposing and developing two Camera cards take considerably longer than the usual ones Camera because it takes 60 seconds to do this compared to 2 χ 2o seconds = ^ o seconds. Not until four Camera cards is the film card camera according to DE-DS 3o 39 R13 with a time of Bo seconds as fast as the πει

common film card camera. Since so far in most cases with the film card camera from one template only a camera card is generated, the film card camera works according to DE-OS 3o 39 B13 despite its complicated Setup is slower than the film card cameras that are already in use. It therefore has no entry into the Found practice.

! The invention is based on the object of a film card

to develop a camera of the type mentioned above, with the

; 2o camera cards generated as quickly as possible one after the other

can be.

This object is achieved according to the invention in that at least two mutually independent development stations are provided and the transport device is designed to feed all development stations.

The film card camera according to the invention works faster

; than that according to DE-DS 3o 39 B13, because immediately after -

• When the exposure station becomes vacant, the next one

Film card exposed and the other development station

ί 3d can be fed. This results in a high level of labor

speed achieved without the film card camera

this becomes complicated in structure. Apart from the required Transport device is only a

The established unit, namely the development station, takes place to be provided once, several times.

The control of the film card camera according to the invention is very easy. The development process in the respective Development station is always started, and one Camera card is inserted. In contrast to this, bostpht with the film card camera according to DE-DS 3o 39 813 Problem that with the clocking of the carousel one card opening device in each case in one treatment station got. However, the treatment stations may only be activated if in the card receiving device a camera card is available in each case, but this only occurs if the time interval between the individual recordings is less than 10 seconds.

Since the film card camera according to the invention has a development cycle takes less than half as long as with the film card camera according to the mentioned publication, can through an automatic density measurement in the film card camera an attribution or processing error very much can be determined quickly, if possible one can be found immediately Recording to be repeated.

An advantageous embodiment of the invention consists in that on both sides of the exposure station opposite one development station is provided. This embodiment is advantageous because it on the one hand, it is particularly simple in terms of construction and, on the other hand, especially when producing two camera cards in each case enables optimally fast work per template. Immediately after removing a camera card the next one can already come from the exposure station

3q camera card can be inserted and exposed. Which subsequent period of the two with only a slight time difference development cycles running almost in parallel

can be used to change the template and usually does not represent a loss of time.

Even this embodiment allows for accordingly quick change of original or in the case of multiple filming, the Create camera cards at intervals of less than 15 seconds. This makes the working speed so high that the compared to a Roll film camera higher operating costs are more than offset by lower wages.

The high speed of operation of the inventive Film card camera and the low stucco costs allow "ep;

therefore often to forego duplicating and instead- §

of which a sufficiently large number of qualitatively superior ■ *

The arrangement of a camera card magazine for unexposed £ Camera cards in front of or behind the reporting |

station between the development stations leads to one: particularly simply designed film card numbers.

Because the transport device, as stated in claim k , for the exclusive loading of only one any of the development stations is designed to be reversible, then if a development station fails as a result of a defect, the film card camera may fail the other development station or the other development stations continue to be used. One gets through this measure a redundant system. The unit, which due to a more complicated structure on the Most likely tends to malfunctions, is at least two times present according to the invention.

It is also advantageous if each development station has its own card outlet. With such an

management form come with the multiple filming of Templates in the individual card outlets are identical Stack of camera cards.

You blenn, as stated in claim 6, in a Level provides three development stations, then vermaq the film card camera to work even faster without its structure becoming significantly more complicated.

The invention can be implemented in numerous ways to · To make it clearer, one of them is shown schematically and spatially in the drawing and is described below described. This shows a film card checker at the front.

The drawing shows the housing 1 of a film card camera which has a card outlet 2, 3 on each of its two narrow sides. Is shown just uiie runs out a camera card U from the housing 1 in order of camera cards k to a stack 5 to arrive in the card outlet. 2

The lens of the film card camera, which is located in the middle of the housing 1 on its underside and forms the heart of an exposure station 6, cannot be seen in the drawing. On both sides of the exposure station 6, a development station 7, θ is provided in the housing 1, in which the exposed microfilm of a camera card b is developed, fixed, soaked and dried in the usual way before it falls into the card outlet 2 or 3.

A camera card magazine 9 is arranged spatially in front of the exposure station G, into which a cassette 1o with unexposed camera cards k can be inserted

fl ItM I ■■ · · «*

Mechanism, not shown, is pushed in each case the topmost of the camera cards from the cassette 1o into the exposure station 6. There is a transport device 11, which can consist, for example, of two pairs of rollers and is capable of transporting a camera card to the development stage 7 or the development station B Transport device, not shown, ensures that the partial camera card h passes out of the housing 1 into the card outlet 2 or 3.

Another detail of the film card camera is in the Drawing shown in phantom, namely an automatic density measuring device in each of the development stations 7, Q, each consisting of a light source 12 and a photocell 13. This automatic density measuring device can still be used in the film card camera immediately after the film of a camera card has been developed measure whether the density of the camera card conforms to the standard and

2ü to display the measured density value digitally, for example in the DE-GM Bo oil 396.3 described.
