Description
Предлагаемое изобретение касаетс киноароектора с оптич;еским выравниванием при посредстве плоского зеркала, в котором е целью отражений изображени применено качающеес зеркало.The present invention relates to a cinema projector with optical alignment by means of a flat mirror in which a swinging mirror is used to reflect images.
Предлагаемый кинопроектор, изображенный на чертеже, схематически состоит из рамки Р,, в которой располагаютс дна кадра фильма f, прот гиваемого через него и ролик R при помощи равномерно и непрерывно вращающегос барабана М, насаженного на оси Н. Дл отражени изобрежений в объектив перед рамкой установлено качающеес около оси Д зеркало D, колебательные движени которому сообщаютс эксцентриком Е, сид щим на валу G приводного механизма, св занного также с осью Г. Дл направлени изображени В объектив ОThe proposed film projector shown in the drawing schematically consists of a frame P, in which the bottom of the frame of the film f is placed, pulled through it and the roller R using a uniformly and continuously rotating drum M mounted on the H axis. a mirror D is swinging about the axis D, the oscillatory movements of which are communicated by an eccentric E, sitting on the shaft G of the drive mechanism, also connected to the axis G. To direct the image B to the lens O
над качающимс зеркалом D установлено добавочное неподвижное зеркало (7.an additional fixed mirror is mounted above the swinging mirror D (7.
Лучи, падающие через отверстие Н и кадры фильма в двух положени х А R Б отражаютс в зеркале D и направл ютс через неподвижное зеркало С в центр объектива О.Rays falling through hole H and film frames in two positions A R B are reflected in mirror D and are directed through fixed mirror C to the center of lens O.
Предмет патента. The subject of the patent.
Кинопроектор с оптическим выравниванием при посредстве плоского зеркала, характеризующийс тем, что зеркалу D сообщаетс ритмическое передвижение эксцентриком Е на валу G, а дл направлени изображени в объектив О служит добавочное неподвижное йеркало С. A film projector with optical alignment through a flat mirror, characterized in that the mirror D communicates rhythmic movement by an eccentric E on the shaft G, and an additional fixed yerkalo C serves to direct the image to the lens O.
