Description

one

The invention relates to the field of radio engineering and instrumentation and can be used to indicate the tuning of radio receivers with a scale and a kaleidoscopic drawing observed on the screen.

In the known devices, a kaleidoscope is located between the light bulb and the scale to indicate the setting, the MOTION: whose element changes the pattern. However, to obtain a kaleidoscopic pattern, a powerful light source is required, and the resulting pattern is static.

The purpose of the invention is to simplify the design and improve the display quality.

For this, in the proposed device, the movable elements are made in the form of opaque or translucent disks arranged parallel to the scale, with openings serving to pass the beams of the light source and form a light image.

FIG. 1 shows a diagram of the proposed device; in fig. 2 - view from the side of the screen.

A disk 2 made of heat-resistant non-transparent material, metal or translucent material, such as colored glass, is installed on the axis of the device I (in this case, a capacitor). Holes of any shape are made in the disk. When moving the handle 3 in front of the light sources 4

and 5 holes appear in the disks 2 and 6, which are projected by the lenses 7 and 8 on the scale of the screen 9, made in the form of a frosted glass.

The disks 2 and 6 are interconnected by the transmission 10, rotate synchronously and connected by the transmission 11 with the handle 3.

The holes in the moving elements are made so that their projection on the screen is visible in

the form of a symmetrical pattern of any shape, for example in the form of a butterfly contour (see Fig. 2), which changes as the handle 3 rotates.

The intersecting beam of rays and the light effect of the display can be changed by alternately opening the openings of the disks 6 and 2 with an additional moving element 12 made, for example, in the form of a rotating disk with holes (the effect of

flickering, changing background, etc.).

In order to obtain a dynamic pattern with a changing color of the indicator, any number of lamps can be used, different in color, for example, a point type with colored glass flasks that illuminate different parts of the screen (marked with numbers 13, 14 and 15 in Fig. 2), controlled by from the remote control or using frequency filters electrically connected in a known pattern with the output of a radio receiver (not shown).
