Abstract

A DEVICE FOR EXPRESSING ADDITIONAL INFORMATION, comprising a light-tight housing in which an illuminator and a disk with labels are installed, characterized in that, in order to provide orientation of the photograph to the cardinal points, it is equipped with a hard disk that is made opaque and tags in it are made in the form of diametrically located openings of a mismatched form. figure 1

Description

The invention relates to photographic technology and can be used in the manufacture of photo plans, in particular in judicial photographs when shooting at the scene.

A device for imprinting additional information in a camera is known, comprising an illuminator, a transparent disk with encoded information, and a coordinate frame 1.

The specified device allows you to imprint the value of the shutter speeds in the frame.

The closest technical solution to the invention is a device for imprinting additional information, comprising an illuminator and a transparent disc labeled 2 placed in an opaque housing.

The disadvantage of this device is that, according to the additional information obtained, it is impossible to orient the photograph to the cardinal points.

The aim of the invention is to provide orientation of the photograph to the cardinal points.

This goal is achieved in that the device for imprinting additional information in the camera, comprising a light-tight housing in which the illuminator and the tagged disk are located, is equipped with a compass, the magnetic element of which is rigidly connected to the disc made opaque, and the marks in it are diametrically shaped. mismatched holes.

FIG. 1 and 2 shows the device, a general view (options).

The device consists of a cover 1 of a camera 2 with a transparent insert 3, a housing 4, a horizontal level 5, an illuminator 6, a magnetic element 7 of the compass, an opaque disc 8, a power supply 9, a transparent strip 10 that presses the film 11.

The cover 1 of the camera 2 has a transparent plastic insert 3 in the area of the personnel window a. The housing 4 of the opaque non-magnetic material serves

to combine parts and eliminate the penetration of external light. Horizontal level 5 — liquid cylinder with a non-magnetic body — allows you to mount the camera 2 horizontally. The lighter 6 is a low-power pulsed lamp with an annular reflector 12 on the inner surface of the housing 4. The magnetic element 7 of the compass is a rotating band magnet, in the absence of sensitivity in the area of the magnetic parts of the camera 2 attached directly to the opaque disc 8. In the case of using the camera 2 with magnetic parts The mi-dansk 8 is removed by distance, eliminating the effect of interference (Fig. 1). The light-tight disc 8 is made of a thin, light, non-magnetic material that has diametrically arranged holes in various shapes at distances not exceeding the smaller side of the frame. The power supply unit 9 serves to power the illuminator 6, connected to a synchronous contact (not shown) of the camera 2. The presser bar 10 is made of a transparent material, replaces the usual bar that presses the photographic film.

The device works as follows.

The camera 2 prepared for shooting is positioned horizontally above the object (not shown). The horizontal position accuracy is controlled by level 5. During remote shooting, electrical switches of horizontal action are used - mercury, radar. Under the action of the magnetic element of the compass 7, the impenetrable disk 8 is oriented in the directions of the cardinal points, with the holes in it located along the "northug" line. At the moment of shooting, the illuminator 6 is turned on, the light passes through the holes in the disk 8, and two points of different shapes (triangle, circle) are imprinted on the film 11, carrying information about the direction of the cardinal points relative to objects sealed in the frame.

The described device provides orientation of the photograph to the cardinal points.
