Abstract

The invention relates to an optical instrument making and simplifies the design of the device. At the ends of the frame frames 4 and 5, pairs of transmitting-receiving coils 10, II and 13, 14 are placed. Wiring, photolite 15 is carried out using a brush 20, kinematically connected with a pair of diagonally arranged coils 10, 14 or II, I3 . Dip changing the direction of the span is used by the lever 26, having the ability to simultaneously act on the projections of the bases 22 and 23. The gear 20 and the lever 26 are freely mounted on an axis 19 located centrally between the frames 4 and 5. The rollers 28 are designed to guide the movement of the photo-tape 15. silt

The invention relates to stereoscopy, namely, devices providing observation of the stereo effect during simultaneous pulling of two tapes with frames fixed on them forming a stereo pair.

The aim of the invention is to simplify the design of the stereoscope.

Figure 1 shows the overall optical layout of a stereoscope; Fig. 2 illustrates the construction of a mirror for illuminating films; FIG. 3 shows a platform structure with coils.

The stereoscope consists of a housing 1, on the front wall of which there are two tubes with oculi 2 and 3 at a basic distance of 6.5 cm between them, which can be moved along the optical axes for focusing. Frames 4 and 5 with frame mirrors 6 and 7 on the outer sides, set at an angle of 45 relative to the outer edges, are located at the same distance from the ocular plane, between the optical axes of the latter, parallel to and at the same distance from them, inside the housing 1. to the framework. Mirrors 6 and 7 are designed to direct the path of the beams from the image within the frames to the respective oculars. Between the frame frames, two mirrors 8 and 9 are symmetrically arranged to reflect natural or artificial light and the axes are performed by the reception of FIG. 1 of the wheels 11 and 13 on gear with the bristles 2 of a pair of gears located on the axes, symmetrical on bases 22 and 2, it is possible to swing from their axes 24 and 25, respectively. The rocker lever 26, which on the axis 19 and the stop are the extreme positions from the buried balls 27, simultaneously lift onto the corner projections of the bases 23 and remove from gearing gear 20 one pa spaced gears engage each other, the role of seed boiling them katu 28 intended for nap photowire voltage. Each holds a head 29. For p

25 Tolent must be rotated 21. At the same time, gear 20 and bucket or coils 11 and 13 must be rotated.

30 MO switch lever 26 position and rotate the pole opposite side. 22 and 23 are rotated, pole 11 and 13 will be released from the hooks of the coils 10 and 14 during

See slides. At both ends, the engagement with gear wheel 20. A single frame frame, in close proximity to them, are two double-feed coils of the same size. The coils 1Q and 11 have the ability to pull the phototape 12 in front of the frame 4 window, and the coils 13 and 14 to phototape 15 in front of the window 5. All the coils sit on vertical petal friction 16 of the driven gears 17 of the same size. The spring clutch clamp 18 serves to fasten the ends of the phototape on the coils. In the center between the frames is the axis 19 of rotation of the central drive gear 20, which is freely mounted on this axis and which is in constant engagement with the driving gear 21, having a manual drive. For deforming images a stereoscope containing

40 ICC channels, each with a mirror-like, optically coupled film frame, and film displacement, performed

45 receiving and transmitting coaxially connected with a scattering structure, kinematich with a drive and with two reciprocating receiving coils of which are installed together with transmitting

These are the role of receivers. In Fig. 1, the wheels 11 and 13 are in engagement with the bristles 20. Each pair of gears located at the same end of the frame is mounted freely on the axes symmetrically located on the bases 22 and 23, having the ability to swing relative to their axes 24 and 25 respectively. The toggle lever 26, which sits freely on the axis 19 and stops in two extreme positions by means of spring-loaded balls 27, has the ability to simultaneously act on the angular protrusions of the bases 22 and 23 and disengage with the drive gear 20 one pair of diagonally arranged gears and enter into engagement with another, thereby changing the role of the coils sitting on them. The rollers 28 are intended to guide the movement of the phototape. Each coil contains a head 29. Gears 21 must be rotated to pass the phototape. At the same time gears 20 and driven gears of coils 11 and 13 will begin to rotate. To pass phototapes in the opposite direction, switch lever 26 to the second position and rotate gear 26 to the opposite the side. The bases 22 and 23 are rotated, the gears of the rollers 11 and 13 are disengaged, and the gears of the coils 10 and 14 are inserted into

gearing with gear 20.
