METHOD OF INPUT OF INFORMATION THROUGH OPTICAL KEYBOARD AND OPTICAL KEYBOARD DEVICE Russian patent published in 2009 - IPC G06F3/23 

FIELD: physics, computer facilities.

SUBSTANCE: invention concerns to the method of input of the information through the optical keyboard and to the device of embodying of the optical keyboard. Technical effect on which achievement the given invention is guided, simplification and expansion of functionality of the optical keyboard. The method of input of the information through the optical keyboard carry out by code interruption of a light stream in a slot-hole light guide on one site and on other following site at the further motion of a key a light stream change proportionally to a key motion downwards and upwards on this site. The device contains the warrant with the microchannels located in the form of a meander and vertical gashes over which the cover having gashes is erected, the warrants executed coaxially with gashes, interreacting with the turned "П"-shaped salients of the code plate erected over a cover at height, equal height of the "П"-shaped salient and a cover of its prominence leaning on parallel gashes against which the code plate the crosspieces leans, thus each "П"-shaped salient for passage of a light stream has horizontal code cracks of different length and interreacts with each key of a keyboard plate.

EFFECT: simplification and expansion of functionality of the optical keyboard.
