Description
Направл юща пластина 11 служит дл направлени движущегос листа 7 через позицию 6 переноса изображени .The guide plate 11 serves to guide the moving sheet 7 through the image transfer position 6.
На позиции б переноса изображени установлена пара коронаторов 12 и 13.A pair of coronators 12 and 13 is installed at position b of image transfer.
Первый коронатор 12 по направлению Чращени барабана 1 с провод щим экраном предназначен дл электрическоi o переноса тонирующих частиц с поверхности барабана на лист копии.The first coronator 12 in the direction of the Turning of the drum 1 with a conductive screen is designed to electrically transfer tinting particles from the surface of the drum to the copy sheet.
Второй коронатор 13 служит дл Уменьшени электрических сил, наведенных во врем переноса изображени , которые стрем тс удержать листы копии у поверхности барабана.The second coronator 13 serves to Reduce the electrical forces induced during image transfer, which tend to keep the copy sheets on the drum surface.
Первый коронатор 12 имеет V-образный экран 14, который расположен йдоль наружного фоторецепторного сло 4 барабана 1.The first coronator 12 has a V-shaped screen 14, which is located near the outer photoreceptor layer 4 of the drum 1.
Открытый конец экрана 14 обраи;ен к поверхности барабана в месте, где листы копий вход т в соприкосновение с фоторецептором.The open end of the screen 14 surrounds the surface of the drum at the place where the sheets of copies come into contact with the photoreceptor.
Внутри экрана 14 имеетс обмотка 15, подсоединйа к источнику посто нного тока 16. Электрический потенциал распростран етс по обмотке 15 и заставл ет ее испускать поток положительных зар дов, проход щий через экран 14, открытый в нижней стороне листа копии.Inside screen 14, there is a winding 15, connected to a DC source 16. The electric potential spreads across the winding 15 and causes it to emit a stream of positive charges passing through the screen 14 opened in the bottom of the copy sheet.
Заземленный экран 14 коротрона действует как электрический регул тор в генерирующей системе и слу сит дл фокусировки однородного потока зар дов на лист копии.The grounded screen of the corotron 14 acts as an electrical regulator in the generating system and serves to focus a uniform flow of charges onto the copy sheet.
Устройство снабжено защитной перегородкой 17, котора защищает копию листа от потока зар дов до тех пор, пока лист копии не окажетс в полном контакте с ксерографической поверхностью .The device is provided with a protective partition 17, which protects the copy of the sheet from the flow of charges until the copy sheet is in full contact with the xerographic surface.
Защитна перегородка 17 выполнена в виде рычага 18, поворотно установленного одним концом на оси 19, и расположена между поверхностью носител изображени и провод щим экраном первого коронатора.The protective partition 17 is made in the form of a lever 18 pivotally mounted at one end on an axis 19, and is located between the surface of the image carrier and the conducting screen of the first coronator.
Положение защитной перегородки 17 регулируетс с помощью регулирующей оси 20.The position of the protective partition 17 is adjusted by means of an adjusting axis 20.
Когда защитна перегородка 17 находитс против регулирующей оси 20, плечо 21 рычага 18 расположено в потоке зар дов, испускаемых коронатором 12, и физически защищает часть пластины от этого потока зар дов. 5 Защитна перегородка 17 имеетWhen the barrier 17 is against the regulating axis 20, the arm 21 of the lever 18 is located in the flow of charges emitted by the coronator 12 and physically protects part of the plate from this flow of charges. 5 protective partition 17 has
выступ 22, который находитс в соприкосновении с нижней поверхностью листа копии, перемещающегос на позицию б переноса изображени . Выступthe protrusion 22, which is in contact with the bottom surface of the copy sheet moving to the image transfer position b. Protrusion
22 заставл ет лист копии отклонитьс вверх до соприкосновени с пластиной фоторецептора в области, защищенной от потока зар дов плечом 21, чтобы лист плотно сел на барабан до того,22 causes the copy sheet to deflect upward until it touches the photoreceptor plate in an area protected from the charge stream by the arm 21, so that the sheet fits firmly on the drum before
5 как на него попадает поток зар дов. Заыит а перегородка 17 состоит из металлического провод щего сло 23, который покрыт тонким слоем 24 диэлектрика.5 how it gets a stream of charges. The barrier 17 consists of a metallic conductive layer 23, which is covered with a thin dielectric layer 24.
Диэлектрическое покрытие достаточно тонко дл того, чтобы электростатический зар д, направленный передающим коронатором, бьйл полностью поглощен слоем 23. Слой 23 заземлен и тем 1самым ограничивает величину зар да,The dielectric coating is sufficiently thin so that the electrostatic charge, directed by the transmitting coronator, is completely absorbed by layer 23. Layer 23 is grounded and thus limits itself the amount of charge,
5 который будет приниматьс диэлектрическим покрытием.5 which will be adopted by the dielectric coating.
