SU1413580A1 - Device for imprinting additional information in a camera - Google Patents

Abstract

The invention relates to photographic technology and can be used in the manufacture of photographs, with the simultaneous registration of additional information in the camera. In the housing 2 of the device, a storage medium is installed, made in the form of a set of dial microindicators 5 of various shapes connected to the control levers 6. For imprinting on the photograph of additional information, the levers 6 are set appropriately with respect to the scales 8. At the moment of shooting, a beam of rays from the illuminator through the diaphragm 9 with the slit Of is projected into the edge of the frame. At the same time, the shadow marks from the microdetectors 5 are imprinted around the perimeter of the frame into the photosensitive layer of photographic film. Micro-indicators 5 are installed in the housing 2 with the possibility of movement along the frame boundaries. 2 Il. (L

The invention relates to photographic technology and can be used in the production of photographs with simultaneous registration in the camera of additional information, in particular in the judicial photograph during taking pictures at the sites of incidents.

The aim of the invention is to increase the amount of additional information simultaneously imprinted in the camera.

Figure 1 shows the device, a general view5 of figure 2 - the same, the bottom part.

The device consists of a camera frame 1 (not shown), a housing 2, an illuminator 3, mirrors 4, pointer micro indicators 5 with control levers 6 moved along grooves 7, scales 8, diaphragm 9, frame 10, transparent strip 11 that presses photographic film 12.

The lid 1 of the camera is fitted with an opaque housing 2, which serves to unite parts and prevent external light from entering. Illuminator 3 is a low-power pulsed lamp, mirrors 4 are located on the inner surfaces of the housing on four sides, reflecting light from illuminator 3 to the edge of the frame. The arrow micro-indicators 5 are information carriers, they have different non-coinciding forms — they differ also when the indicators are located along the same optical axis. Control levers 6 are used to set pointers 5 and have an indicator risk. The slots 7 are made opaque, and the levers move along them. Scales 8 with linear and digital indices are located outside on the walls of the body, designed to index the control levers 6 by their position. The diaphragm 9 is made opaque, has a slot along the perimeter of the frame, and serves to form shadow marks on the film. Frame 10 ia opaque material closes access to the edge of the frame of basic information from the camera lens. Transparent

The flash 11 presses the film 12 against the film guide.

The device works as follows.

Additional information is required in the camera prepared for shooting (snapshot number, date,

time, exposure, aperture, etc .;) by setting the indexes of the control levers 6 against the values of the respective scales 8. The micro-indicators 5 connected to the control levers occupy certain positions in the aperture zone c of the diaphragm 9. At the moment of shooting the illuminator 3 turns on, light mirrors 4 is reflected through the slit in the diaphragm 9 to the edge

part of the frame, while the shadow marks of a non-coincident form from microindicators located on the path of the light flux are printed around the perimeter of the frame into the photosensitive layer of photographic film 12.

With the full coincidence of the position of the microdetectors, the tags form a total figure, allowing to distinguish the signs of each microindex. The main information in the area of additional information is not received due to the screening effect of the frame 10. After the film is developed, the frames are increased to the selected

the scale and shape of the labels set the values of the imprinted information data.
