Around the end of the 1950 years there were developed one of the most interesting cameras. The Alycha document copying camera through the scan method.. The rollover technique was unknown to the west so various documents were copied during the “Cold War” without the knowledge of people. This was a landmark on camera creation due to the Soviet photo-camera designers.
Here we place the working system of those camera types:
The image from the “TEXT” reflects to the mirror “M”, turns around the 90° total reflecting prism “P1”, passes through the objective “O”, the Dove prism “P2”, which is placed at a 45° relative to the optical axis in order to correct the image position projected to the slot “SL” where the film passes through. This fantastic slot acts also as shutter once tit width is of only 1/40- 1/45 of mm! “FS” are the film spools. “FC” is the film chamber. A special cutter comes with the device cutting a standard 35mm film in three strips of 8mm each in the whole 1.6m length.
Two switches act as protection against waste of batteries, “S1” turns “on” when the “booklet” is opened, the other”S2” lights the lamp when it detects the rolling movement of the wheel “T”. A main wheel drive actuates an endless screw “ES” that drives the film through the pivot “RT” a mechanical device with “zero” tolerances in a reduction ratio equal to the optical reduction (in the Alycha -1 : 12,8-)
The special lamp ”L” is designed to cover all the lens encompassed field in order to give no shadows without the need of any reflector, that way t has only 3mm of diameter and 100 mm long in an all size glowing arrangement.
The “booklet” cover is built only to maintain exact distances of the whole system.
The device uses special DEAC rechargeable batteries.
