Description

Изобретепие относитс  к области электрофотографии , а точнее к про влению скрытых электростатических изображений жидким про вителем .The invention relates to the field of electrophotography, and more specifically to the development of hidden electrostatic images by a liquid developer.

Известно устройство дл  подачи про вител  на цилиндр со скрытым электростатическим изображением, содержащее емкость с про вл ющим раствором, подающий валик, установленный в емкости, аппликаторны валик с пластинчатым скребком, расположенный между цилиндром и смачивающимс  валиком с возможностью взаимодействи  с ними.A device for supplying a developer to a cylinder with a latent electrostatic image is known, which contains a container with a developing solution, a feed roller installed in a container, an applicator roller with a plate scraper, located between the cylinder and a wettable roller with the possibility of interaction with them.

Иедостаток известного устройства состоит в том, что на концах апнликаторного валика скапливаетс  излищнее количество про вител , который в процессе про влени  по кра м оттиска образует фон.The disadvantage of the known device is that the ends of the applicator roller accumulate more than the amount of the developer, which in the process of developing along the edges of the print forms the background.

С целью устранени  фоновых полос на оттиске в предлагаемом устройстве на концах анпликаторного валика установлены дополнительные уголковые скребки.In order to eliminate the background stripes on the print in the proposed device, additional corner scrapers are installed at the ends of the applicator roller.

На фиг. 1 дана схема предлагаемого устройства; на фиг. 2 - форма выполнени  скребков .FIG. 1 is a diagram of the proposed device; in fig. 2 - the form of execution of the scrapers.

Устройство состоит из емкости 1, паполненной про вл ющей жидкостью, в которой установлен подающий валик 2, взаимодействующий с аппликаторным валиком 3. Аппликаторный валик снабжен основным пластинчатым скребком 4 с держателем 5 и дополнительными боковыми скребками 6 с держател ми 7. Валик 3 взаимодействует с фотопровод щей поверхностью 8.The device consists of a container 1 filled with a developing liquid, in which a feed roller 2 is installed, which interacts with the applicator roller 3. The applicator roller is equipped with a main plate scraper 4 with a holder 5 and additional side scrapers 6 with a holder 7. The roller 3 interacts with the photo conductor surface 8.

Устройство работает следующим образом.The device works as follows.

Подающий валик 2 при своем вращении переиосит про витель на анпликаторный валик 3. Пластинчатые скребки 4 и 6 снимают излишки про вител  с наружной и торцовой поверхностей аппликаторного валика. При последуюн1 ,ем вращении аппликаторного валика его поверхность соприкасаетс  с фотонровод щей поверхностью, несущей скрытое электроста гическое изображение.The feed roller 2 rotates the developer on the applicator roller 3 during its rotation. The lamellar scrapers 4 and 6 remove the excess of the developer from the outer and end surfaces of the applicator roller. During the subsequent rotation of the applicator roller, its surface is in contact with the photon-conducting surface that carries the latent electrostatic image.

Кроме того, вместо апиликаторного валика можио примен ть аппликаторную ленту или ткань.In addition, an applicator tape or cloth may be used instead of an apilicator roller.

Предмет изобретени Subject invention

(стройство дл  подачи про вител  на цилиндр со скрытым электростатическим изображением , содержащее емкость с про вл ющим раствором, подающий валик, установленный в емкости, аппликаторный валик, расположенпьп между цилиндром с изображением и издающим валиком с возможностью взаимодействи  с ними, и пластинчатый скребок , закренлениый на внещней иоверхности апиликаторного валика, отличающеес (a device for supplying a developer to a cylinder with a latent electrostatic image containing a container with a developing solution, a feed roller installed in the container, an applicator roller located between the image cylinder and the issuing roller with the possibility of interaction with them, and a lamellar scraper, fastened on the outer surface of the apilicator roller, characterized by

тем, что, с целью улучшени  качества оттиска, на концах аппликаторного валика дополнительно закреплены уголковые скребки дл  удалени  излишков про вл ющего раствора.By the fact that, in order to improve the quality of the imprint, angular wipers are additionally fixed at the ends of the applicator roller to remove excess developer solution.
