Изобретение относитс к области электрофотографии .This invention relates to the field of electrophotography.
Известно устройство дл про влени цветного изображени в электрографическом аппарате, содержащее емкость дл про вл ющей смеси с размещенными в ней транспортирующим средством, передающим валиком, одним или несколькими валиками магнитной кисти и привод транспортирующего средства 1.A device for manifesting a color image in an electrographic apparatus is known, which contains a container for a developing mixture with transporting means, a transfer roller, one or several rollers of a magnetic brush, and a drive of the transporting means 1.
Однако известное устройство не дает достаточно хорошего качества изображени в многоцветных аппаратах из-за фиксированного закреплени про вл ющего устройства .However, the known device does not provide a sufficiently good image quality in multi-color apparatus due to the fixed fixing of the developing device.
Целью изобретени вл етс повыщение качества изображени .The aim of the invention is to improve the image quality.
Указанна цель достигаетс тем, что емкость дл про вл ющей смеси установлена на опорах подвижно и имеет ролик дл установки зазора между емкостью и поверхностью носител изображени аппарата , св занный с пружиной сжати дл отвода емкости от поверхности носител записи .This goal is achieved by the fact that the capacity for the developing mixture is mounted on supports movably and has a roller for setting the gap between the capacity and the surface of the image carrier of the apparatus, associated with a compression spring for draining the container from the surface of the recording medium.
На фиг. 1 показано расположение устройств дл про влени в многоцветном электрографическом аппарате; на фиг. 2FIG. 1 shows the arrangement of devices for development in a multicolor electrographic apparatus; in fig. 2
более подробно показана конструкци одного из устройств дл про влени .The construction of one of the development devices is shown in more detail.
Устройство дл про влени имеет емкость 1, транспортирующее средство 2, передающий валик 3, валик 4 магнитной кисти , привод транспортирующего средства, щестерню 5 зубчатой муфты и шестерню 6. Емкость 1 установлена на опорах 7 и 8 подвижно и имеет ролик 9, св занный с пружиной сжати 10.The development device has a capacity 1, a transporting means 2, a transfer roller 3, a magnetic brush roller 4, a drive of the transporting means, a gear coupling gear 5 and gear 6. The container 1 is mounted on supports 7 and 8 and has a roller 9 connected to compression spring 10.
Устройство работает следующим образом .The device works as follows.
Когда устройство дл про влени находитс в нерабочем состо нни, пружина 10 отводит корпус 1 от поверхности носител И изображени . В этом положении валик 4 магнитной кисти отведен от поверхности носител 11.When the development device is in an inoperative state, the spring 10 retracts the housing 1 from the surface of the carrier AND the image. In this position, the roller 4 of the magnetic brush is retracted from the surface of the carrier 11.
В рабочее положение устройство дл про влени переходит тогда, когда шестерн 5 зубчатой муфты входит в зацепление с шестерней 6, котора соединена с транспортирующим средством 2, представл ющим собой совковое колесо. В результате зацеплени совковое колесо поворачиваетс по часовой стрелке. Как только шестерн 6 и совковое колесо начинают вращатьс , на емкость 1 действует сила сопротивлени Движению со стороны про вл ющей смеси, котора находитс в нижней части емкости I. Сила, противодействующа силе сопротивлени про вл ющей смеси, заставл ет емкость 1 повернутьс по часовой стрелке против усили пружины 10, пока ролик 9 не коснетс поверхности носител 11 изображени , образовав зазор, и начинаетс процесс про влени . После про влени изображени приводной мотор (не показан ) отсоедин етс от шестерни 5, и движение совкового колеса прекращаетс . Пружина 10 сжати поворачивает емкость 1 на шарнирах опор 7 и 8 в нерабочее положение . Это завершает цикл работы.The development device switches to the working position when the gear 5 of the gear coupling engages with the gear 6, which is connected to the transporting means 2, which is a scoop wheel. As a result of the engagement, the shovel wheel rotates clockwise. As soon as gear 6 and the sovok wheel begin to rotate, capacity 1 is affected by the resistance force to the motion from the side of the developing mixture, which is located in the lower part of tank I. The force opposing the force of resistance of the developing mixture causes the capacity 1 to turn clockwise against the force of the spring 10 until the roller 9 touches the surface of the image carrier 11, forming a gap, and the process of manifestation begins. After the image has been developed, the drive motor (not shown) is disconnected from gear 5, and the movement of the scoop wheel is stopped. The compression spring 10 rotates the capacitance 1 on the hinges of the supports 7 and 8 to the non-operating position. This completes the work cycle.
Неподвижна установка каждого устройства дл про влени позвол ет повысить качество про вл емого цветного изображени .The fixed installation of each device for the development improves the quality of the developed color image.
