Definitions
- the invention relates to a photo camera with a housing and a film strip with two or more lenses, which can be moved gradually in a direction of motion in the film, and a shutter mechanism that opens closures associated with the individual lenses one after the other in order to expose sections of the film strip associated with the individual lenses, preferably adjacent to one another. and with a trigger, in particular designed as a push button, for the locking mechanism.
- Such multi-lens photo cameras in which images are taken in succession on the individual lenses on a film strip standing during the triggering process, are already known per se, for example from US Pat. No. 5,210,557; US-A 5,264,882, US-A 5,424,729, US-A 5,363,161 and US-A 5,884,307.
- the film it is common for the film to move horizontally in a normal position of the camera, with the trigger being conveniently located on the top, typically out of a film cartridge, past the closures and lenses to a winding shaft actuated by a winding mechanism. After the entire film has been exposed, it is then rewound into the film cartridge.
- a standard negative image is divided into sections lying next to one another, these sections being exposed one behind the other by the individual lenses. Since these sections are naturally smaller than the area of a standard negative image (for example 24 mm x 36 mm), it is important to fill the available area of such a standard negative as completely as possible with the individual sections that are assigned to the respective lenses.
- two-line lens arrangements as in US Pat. No. 5,264,882 have been selected, while in the case of single-line lens arrangements, such as in US Pat. No. 5,210,557, the individual sections of the respective lenses do not even use the area of a standard negative to almost any extent.
- the object of the invention is to provide a novel multi-lens photo camera of the type mentioned at the outset, in which the film strip to be exposed can be used well with regard to the total exposed area and in which more favorable image formats are possible.
- this is achieved in a photo camera of the type mentioned above in that the direction of film movement in a normal position of the photo camera, in which the trigger is on the top, runs from top to bottom or vice versa, preferably vertically.
- the basic idea of the invention is to set the housing upright in a multi-lens camera and to arrange the trigger at the top.
- the film is thus moved essentially vertically from top to bottom or from bottom to top. If a single row of lenses lying vertically one above the other in this normal position is used, each of these lenses can expose a relatively wide section of the film strip, it being preferably provided that each of the lenses exposes a section of the film strip which - with the photo camera normal position - has its width in each case corresponds to the height of a standard negative image, preferably 24 mm, and which corresponds in each case to a value B: Z, where B is the width of the standard negative image, preferably 36 mm, and Z is the number of lenses.
- the image formats assigned to the individual lenses can be at least twice as wide as high.
- the individual images can thus have image formats similar to those of the so-called "panorama images" known hitherto. This has a particular advantage in multi-lens cameras which take images at different times, because the objects generally move horizontally. If one now has a larger image width Then, even with the camera held back, it is better to ensure that the desired object is actually on the picture on all the shots taken in succession during a release process.
- FIG. 1 shows a schematic view of an exemplary embodiment of a photo camera according to the invention
- FIG. 2 shows part of a film strip with the exposed, adjacent, exposed sections assigned to the individual lenses.
- the photo camera shown in FIG. 1 has a housing 1 and a film strip 3 which can be moved therein step by step in the direction of film movement 2.
- the film strip 3 for example a negative image film in the 24 mm x 36 mm image format, is accommodated in a commercially available film cartridge 4 and is wound onto a winding shaft 6 via a winding mechanism 5 (not shown in more detail), the gradual movement between the individual multiple exposure processes taking place.
- the winding mechanism 5 can be actuated by a rope 7 wound on a winding spool and a ring 8 attached to its end. On the ring 8, the cord 7 is pulled out of the housing 1 of the photo camera, as a result of which the winding shaft 6 moves by an image feed.
- other known winding mechanisms for example in the form of a tensioning lever or electrical elevator mechanisms, can also be used here.
- the photo camera of FIG. 1 has four identical lenses 9 arranged one above the other. During a multiple exposure process caused by
- Pressing the trigger 10 arranged above in the direction of arrow 11 triggers a schematically illustrated shutter mechanism 12 to open the lenses 9 or the shutter arranged behind them in succession, for example within one second, in each case with an exposure time (for example of 1/125 sec.).
- This locking mechanism 12 need not be described in detail here, since it can basically belong to the prior art. For example, are suitable
- the film movement direction 2 of the film strip 3 of the normal position of the photo camera shown in FIG. 1 runs from top to bottom or from bottom to top, preferably vertically.
- the normal position of the camera is defined in that the trigger 10 is located on the top 1a of the housing of the camera 1.
- the actuation direction 11 of the trigger 10 which is preferably designed as a push button, and the film movement direction 2 thus run in a line, while the axes of the film cartridge 4 or the winding shaft 6 are essentially perpendicular thereto.
- the trigger 10 can be designed differently, for example as a lever.
- the exemplary embodiment according to the invention explained in more detail in FIGS. 1 and 2 has four lenses 9 lying one above the other in a single row.
- sections 3a, 3b, 3c and 3d on the film strip 3 are thus exposed in a multiple exposure 4, each of these sections 3a to 3d being assigned to one of the lenses 9.
- the height H ⁇ , H 2 , H 3 and H 4 of each such section 3a, 3b, 3c and 3d corresponds to a quarter of the width B of a standard negative image (for example 9 mm in a standard negative film with a width of 36 mm).
- the image formats of the individual sections are considerably wider than high, for example in the format of a
- a horizontally moving object can easily be accommodated on the image on all four successive shots, whereby the camera can be held comfortably in the normal position, ie with the trigger on top
- Fig. 2 shows the male as "positive” for the sake of clarity. Of course, in reality it will be mirrored on the negative.
- FIG. 2 is understood to be a schematic illustration.
- the entire area of a standard negative image (for example 24 mm ⁇ 36 mm) can also be used essentially completely for exposure with the photo camera according to the invention, which represents a further advantage.
