Photogi-aphic or clnematographic camera with

a power source

The innovation concerns one photographic or cinematographic Camera with a power source for camera functions, such as film transport and / or exposure control and / or Flash light and / or the like.

Cameras with these features are known in a wide variety of designs and from numerous examples. To avoid "that with such a camera by the absence of the power source fails exposed images are made, will hit one in the structure is simple and cheap to manufacture equipment before, which tells the camera user that no power source is available in the camera.

This problem is solved according to the invention that a Insertion lock prevents the insertion of the film cassette or the film cartridge into the camera when the power source is not available. Further details of the innovation are on hand Described and explained in more detail in the embodiment shown in the drawing.

Show it

1 shows a perspective illustration of a camera, seen from the rear, without a rear cover and without a power source with a film cassette;

FIG. 2 shows the camera according to FIG. 1 with an inserted power source and film cassette;

3 shows a part of the camera with a differently designed battery chamber

In the camera housing 1, the two film receiving chambers la and Ib are embedded in such a way that the film cassette 5 with its film supply chamber 5a and its film take-up chamber 5b, which are equipped with a Film guideway are connected to each other, can be inserted. RLe increase Ic forms the support for the film cassette The film receiving chamber la is enlarged towards the outside, so that a battery chamber Id is created. Between the outer wall

of the camera housing 1 and the side wall Ie of the Batteriekarraner are the angle I-shaped contacts 2 and 3 for the Current source 4 introduced. Your contact arms 2a and 3a occur through slots If and Ig in the side wall ie into the Battery chamber Id into it. The arm 3a of the contact 3 rests the upper wall of the battery chamber Id. The arm 2a of the lower contact 2 is resilient and has an extension 2b.

If there is no film cassette, or if there are other types of camera No film cartridge and no power source are located in the housing 1, the spring arm 2a is at an acute angle from the bottom surface and protrudes with its extension 2b into the film receiving chamber la. In this one shown in FIG Position “a” thus serves the extension 2b of the contact spring 2 as an insertion lock for the filter cassette 5. If you wanted to insert the cassette 5, the film supply chamber 5a of the cassette would be on the extension 2b of the contact spring 2 come to rest and the back cover of the camera could not be closed. When inserting the power source 4 the spring arm 2a pivots from position "a" to position "b" (Fig. 2), wherein the extension 2b comes to rest in a recess lh on the bottom of the film receiving chamber la and the entire Film recording chamber la releases.

A grip groove 8 is attached to the bottom of the battery camera ld, which allows the power source to be easily lifted and exchanged despite the inserted film cassette can. After the power source has been lifted off, the Federann 2a is somewhat relaxed from the film supply chamber 5a of the film cassette held and brought back into the tensioned position when a new power source is inserted via the contact tongue 2c.

As can be seen from Fig. 3, there is between the battery chamber Id and the Pi lmauf receiving chamber la a continuous partition 6, through the slot 6a of the extension 2b Contact spring 2 protrudes into the film receiving chamber.

Of course, the innovation is not limited to the example described. Thus, as can also be seen from FIG. 3 is to be accessible from the side through a closable opening 7, the battery chamber. Furthermore, (not shown) a linkage controlled by the battery contacts 2 or 3 can be used as an insertion lock.
