Photographic camera with a slider

The invention relates to a photographic camera with a
Slider for covering camera parts, such as the lens,
and / or for film transport, which in its use position protrudes over the camera housing, wherein in the front

standing part a viewfinder is arranged, and in its non-; position of use at least partially over the camera housing j

is pushed. I.

to be able to make visible the viewfinder.

An arrangement that achieves this problem has the advantage that the mechanical and electrical control means for the Display means can also be arranged permanently in the camera housing and do not need to be pulled out with the slide and therefore easy to adjust and that the mirroring means too for the display means, in turn, can be provided in the slide so that they are fixed and therefore easily adjustable.

This object is achieved according to the invention by the features of the main claim.

Further advantageous features of the invention are set out in the subclaims can be removed and are explained in more detail with reference to drawings. Show it

The housing of a camera is denoted by 1 in the figures. It is designed as a long, flat cuboid, on which the non-visible lens is arranged on a longitudinal narrow side is, while from the other longitudinal narrow side 2 film cassettes can be inserted into the camera by means of a cover. The position of the lens is indicated by the dash-dotted axis indicated. The housing 1 is offset inwardly in the two flat sides in an L-shape, with a the L-shape of the same adapted slide 5 is slidable to to lock camera 1 when not in use. In the non-use position covers the narrow side of the long leg of the slide 3 from the lens. When using the camera the slide 3 according to Figure 1 is pulled out from the camera 1 so that it releases the lens. The slide 3 can also be used as Be formed film transport slide. The slide J is guided on the camera housing 1 in a known manner.

The camera housing 1 has recesses 1b, 1c or corresponding ones designed free spaces are provided which are large enough to accommodate a viewfinder lens 6 and a viewfinder lens 8, the possibly also the carrier of a mirror for reflecting in image field delimitation marks according to the Albada principle and on Slide 3 is attached to be able to slide in the rest position of the slide 3.

The finder lens 8 is together with a finder ocular lens combined in a carrier part 9 to form a structural unit, which is inserted into the slide 3. In addition, the viewfinder objective lens 6 is on the slide 3 and 9 on the carrier part a mirror 11 for reflecting a display means 10 is provided.

The display means 10 lies in a substantially parallel manner The pocket 1d of the camera housing 1, which is directed towards the direction of movement of the slide 3 and is open towards the slide 3, can for example from one or more light-emitting diodes to display the lighting conditions or the operational readiness of a Flash or from a perpendicular to the direction of movement of the slide 3 movable aperture, exposure time or Light value scale, which is illuminated from behind by a lamp, exist. The arrangement of the pocket 1d in essentially parallel to the direction of movement of the slide, it is achieved that the output from the display means 10 Light beams predominantly run parallel to the direction of movement of the slide 3. At the slide 3 on the edge of the Support part 9 is preferably inclined at about 45 ° with respect to the light rays of the mirrors coming from the display means 10

provided that in every position of the slide 3 the light rays coming from the display means 10 into the edge area of the image field of the viewfinder eyepiece 7 is reflected. The inclination of the mirror 11 with respect to that of the display means Incoming light rays may vary by 45 ° if this is the case the spatial conditions in the viewfinder, e.g. B. the angle of view of the ocular lens 7 or the distance between the lenses 7 and 8 makes it seem appropriate.

The directed approximately parallel to the direction of movement of the slide 3 The direction of radiation of the display means 10 has the advantage that the display means 10 is fixedly arranged in the camera housing 1 and can therefore be rigidly connected to the parts whose setting it indicates, and that nevertheless the mirror 11 for reflecting the display means in the viewfinder beam path in turn fixed in the movable together with the slide 3

Of course, other configurations, not shown in the drawings for the sake of simplicity, are also possible according to the invention.

jfindung possible. So could in front of the display means 10 a small lens may be provided, which the emanating from the display means 10 light rays -essentially parallel to the movement direction of the slide 3 aligns. Naturally, the mirror 11, whatever the inclination, must be in the area of the from the display means 10 coming light rays lie, so have the same distance as from the long narrow sides of the camera the display means 10.
