DE2342576A1 - Miniature pocket camera with telescoping housing - has viewer and flash cube socket on extending part - Google Patents

Abstract

The telescoping camera housing is designed to reduce overall dimensions when the camera is not in use. The extending movement is used to transport the film and set the shutter. The front and rear viewfinder lenses are fixed in the extending part so that in the closed position they lie in front of and behind the film cassette chamber respectively. The rotating flash socket is fitted in the outer end of the telescopic section. Flash ignition can be by percussion, piezo electric or by battery. The design provides adequate spacing between camera lens and flash bulb to avoid the "red eye" effect.

Patent application Photographic camera

The invention relates to a photographic camera with a flat, elongated housing extending in its longitudinal direction Is designed telescopically collapsible and expandable, and its collapsed by one Non-use position into an extended use position Movable housing part transfers the viewfinder from a non-use to a use position and vice versa.

Photographic, so-called miniature cameras have become known which, when not in use, are very small Have shape. Especially in the case of the DT-GM 1 454 known miniature camera, the lens and the viewfinder are arranged in a camera body, which is displaceable by a Housing part are covered or released. The viewfinder of this camera is to the side of the film chamber and thereby increases the length of the camera.

509810/0927

Should become known with this through the DT-GM 1 454 419 Small camera flash photos are taken, so this is the need to carry and attach a flash unit necessary, whereby the original advantage of handiness is diminished again, especially one that has to be carried Additional device can be forgotten or lost and the camera is then not fully operational.

In such miniature cameras, which inevitably have small dimensions, is particularly in cameras with built-in Flash lamp holder solve the problem as the lens and the flash lamp are at a sufficiently large distance can be arranged from each other, us the so-called Eliminate red-eye effect.

It is the object of the invention to design a miniature camera so that it can be pushed together in particular State has small dimensions and also the distance necessary to avoid the so-called red-eye effect between the lens and the flash lamp.

The solution to the problem posed is contained in the claims and is explained with reference to the drawings. All Parts not necessary for understanding the device have been omitted from the drawings. Same parts of the different exemplary embodiments are provided with the same reference symbols.

Pig. 4 the camera according to Pig. 3 in the collapsed State.

The device will first be described using the exemplary embodiment according to FIGS. 1 and 2. The camera body 1 is seen as a rigid part, on which all accuracy-dependent elements that affect the image quality influence (lens arrangement, cassette film support and shutter), as well as all image step influencing Elements (barrage, film transport) are arranged.

In this camera housing 1, the cassette 2 with the film 3 (indicated by dashed lines) is thus stored in a film chamber. On the camera housing 1, the movable housing part M is arranged, which is shown in FIG. 1 in the expanded state (camera ready for operation). The viewfinder with the viewfinder lenses 5 and 17 and the laterally arranged flash cube holder 6 for impact-ignitable flash cubes 7 are located in the movable housing part H

Behind the lens 8 is the shutter 9, which at the same time directly or indirectly as a drive for the ignition slide 10 serves. -

The mode of operation of the device is as follows: If the shutter 9 is released, it moves the ignition slide 10 in the direction of arrow "A", igniting a flash lamp in a known manner.

From Fig. 1 it can be seen that the distance "X" from the lens 8 to the reflector 7a of the flash cube 7 is relatively is great. This will eliminate the red-eye effect *.

If no picture is to be taken, the housing part k is pushed telescopically into the camera housing 1 in the direction of the arrow “B”. Under the action of a weak spring 11, the ignition slide 10 moves out of the area of action of the lock 9.For this purpose, an inclined surface 10a on a housing-side pin 12 on the ignition slide 10 can slide in order to bring the ignition slide 10 into the desired inoperative position. At the same time, the viewfinder lenses 5j 17 are pushed into the camera housing 1 in front of and behind the cassette 2.

In the collapsed, non-functional state, the camera assumes the position shown in Fig. 2, the length of the camera being reduced to a minimum essentially determined by the length of the cassette (the The separation point between the rigid camera housing 1 and the displaceable housing part 4 is denoted by la in FIG. 2)

The lightning cube rotating mechanism is shown in FIGS Omitted for the sake of clarity and shown in FIGS. 3 and 4. In FIGS. 3 and 4, the same became Reason to omit the representation of the ignition mechanism according to FIGS. 1 and 2. Both devices are with both Embodiments are the same, with the second embodiment according to FIGS. 3 and 4 having a different viewfinder design is pictured.

The transport lever 13 can be rotated about the pivot point 21 (FIG. 3) stored, which on the one hand with the cams 6a of the lightning cube socket 6 and on the other hand via the bend 13a with a pivot lever 14, which is also pivotably mounted, cooperates.

The device works as follows:

When you operate the switch handle 15 (shown in dashed lines) in the direction of the arrow "C" are through Means, not shown, the shutter 9 is stretched and the film 3 is transported by one frame step. The Deflection lever 14 around the pivot point 16 in the direction of the Arrow "D" and driven by this the transport lever is pivoted about the pivot point 21 in the direction of the arrow "E", As a result, the flash lamp holder 6 and thus the flash cube 7 are rotated further by one position via the cams 6a will.

When the movable housing part 4 is pushed in in the direction of the arrow "B" (FIG. 4), the transport lever 13 is in brought a functionless position separate from the lever 14 within the camera housing 1.

Deviating from this function applicable to both exemplary embodiments, according to FIGS. 3 and 4, those around the bearings 18, 2o rotatably arranged finder lenses 5, 17 through the webs 4a, 4b located on the movable housing part 4 according to FIG Fig. 3 detected on the projections 5a> 17a and pivoted so, that the viewfinder lenses 5, 17 laterally adjoin the cartridge chamber. The camera is now in the collapsed state brought back to a minimum length essentially dependent on the cassette 2.

In the collapsed state, a bracket 4c of the movable housing part 4 covers the lens 8 and thus serves as protection against contamination of the lens 8 and the shutter 9 Release and / or elevator lock be connected (not shown).

As FIGS. 1 to 4 show, on the movable housing part 4, in addition to the flash lamp socket 6, preferably Also on the front side, a plug-in means 19 (e.g. plug-in shoe) for attaching electronic flash units or other electrically ignitable flash units. Even with the plug-in means arranged on the side attached flash units, the distance to the lens 8 is increased, so that the so-called red-eye effect is eliminated will.

Deviating from the embodiment described, in which the storage of the impact energy for the ignition slide V ^ and the rotation of the flash lamp holder 6 are carried out by a switching handle 15, it is also conceivable (not shown) to perform these clamping and switching operations as a function of pulling out and / or by pushing in the movable housing part ¹ J.
