Abstract

The invention relates to a photographic technique and reduces shock loads by ensuring the camera is bumpless. The mechanism for switching off the device is made in the form of two-arm levers 9 and 25 and a spring-loaded link 11 with holes, kinematically connected with lever 27. When the disk 14 leaves the engagement, the engine starts to rotate through the clutch B into shaft 7. At the moment of contact of the lever 29 with the eccentric 33 lever 30, a shutter curtain 31 is opened. The tape mechanism is driven by rolling the wheel 20 around the stationary wheel 18. When the specified angle of rotation is ensured by the action of the lever 27 on the link 11, the levers 9 and 25 release the wheel 19 and the toothed crown of the drum 5, 4 or less.

Description

This invention relates to a photographic technique.

The purpose of the invention is to reduce impact loads by providing an unaccented shutdown of the camera.

FIG. 1 is a schematic diagram of a camera mechanism; in fig. 2 - the rocker of the shutdown mechanism of the camera; in fig. 3 is a diagram of the camera part of the camera; Fig. 4 shows the slide of the shutdown mechanism after turning the chamber part to the required panning angle.

The panoramic camera consists of the mechanical part 1, the camera 2 mounted on the rotating base 3, the handle 4, the drum 5 with the shaft 6, which is connected to the shaft 7 of the rotation mechanism through the coupling 8, two shoulders lever 9 with the axis 10 of rotation mounted with meshing with the ring gear of the drum 5, the link 11 with the axis 12 of rotation, the spring 13, the disk 14, one tooth of which engages with the trigger device 15 by means of a spring (not shown). The triggering device 15 passes through the opening 16. In addition, the camera contains a rod 17 to prevent the spontaneous triggering mechanism i, wheels 18 and 19 interconnected and mounted with the possibility of free rotation on the shaft 7, gears 20 and 21, mounted on the axis 22, the receiving coil 23 and the drum 24. The radius of the wheel 18 is equal to the focal length of the lens. The double-shouldered lever 25 is held by the link 11 in engagement with the wheel 19. The device includes a spring-loaded ball 26, a lever 27 mounted to be fixed in a certain place of the base 3 depending on the required angle of rotation, the levers 28-30, the last of which moves the shutter curtain 3 32 and eccentric 33.

Panoramic camera works as follows.

After the trigger lever 15 is pressed, the rod 17 is lowered under the action of the spring, the disk 14 comes out of engagement and the spring motor starts to rotate the shaft 7 through the coupling 8. The lever 28 acts on the lever 29, which moves until it contacts the eccentric 33. Simultaneously the lever 30 opens the shutter 31

the shutter 32. After contact with the eccentric 33, the lever 29 transmits the engine force to the base 3, which begins to rotate. The wheel 20, driven around the fixed wheel 18, activates the tape drive mechanism.

When the desired angle of the gate is reached, the lever 27 acts on the slide 1, which is shifted to the position shown in FIG. 4. As a result, the two shoulders levers 9 and 25 release the wheel I9 and the toothed rim of the drum 5.

The wheel 18 begins to rotate along with the wheel 21 by inertia, slowing down under the influence of friction forces. In this case, the drum 5 rotates in the opposite direction under the action of the unused energy of the spring. The clutch 8 allows the shaft 6 to rotate by inertia with the drum. To prepare the machine for the next cycle, it is necessary to transfer it to its original position.
