FIELD: teaching aids. SUBSTANCE: language teaching facility is facility designed for individual teaching foreign languages both under usual conditions, in class and at home, and under conditions unusual for such study: while walking, in metro, in bus, etc. Key direction in work with facility consists in visual study of vocabulary. Design of facility is simple but reliable, main element of facility is conveyer belt turning on two rollers. Conveyer belt comprises two parallel pulled rubber wheels between which clear flat boxes- containers extended in shaped and open on face are arranged. Information cards carrying words, their translation and transcription are put into them. Entire belt with boxes-containers and cards is placed into rounded body possessing rectangular window. Upper part of body has two buttons, with pressing of buttons motion is transmitted to one of rollers rotating rings. As result entire belt with containers and cards in them is turned. Containers with cards pass in front of inspection window replacing one another after each pressing of button. Buttons match gears of drive shaft with opposite direction of rotation and turn conveyer belt differently: one-forward and another- backward. Cards in containers are replaced by direct pushing of old card with new one. This operation occurs in container which is at present moment under inspection window. Card fall-out from container located under inspection window is prevented by blocking buttons spring-loaded from beneath, buttons in free position block off face exits from container. Natural space that can be used to position mobile pocket for replacement cards for facility is formed in conveyer belt. It is suggested that cards for facility should made of pressboard and should be presented to user in the form of pressboard sheets with stamped cells-cards held in sheet with the help of two thin straps. Required cards are broken off out of sheet by user and loaded into facility. EFFECT: enhanced functional efficiency. 19 dwg
