本発明は静電記録装置にお【プるマルチスタイラスのク
リーニング装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cleaning device for a multi-stylus used in an electrostatic recording device.
第１図は、マルチスタイラスを備えた一般的な静電記録
装置を概念的に示づものである。FIG. 1 conceptually shows a general electrostatic recording device equipped with multiple styluses.

記録紙ロール５から供給される記録紙５ａに転写する。In this device, as the photoreceptor 1 rotates, a charging corotron 2 uniformly charges the surface of the pel 1 to the state photoreceptor 1, and then a multi-stylus 3 forms an electrostatic latent image on the surface of the photoreceptor. Then, this electrostatic latent image is visualized by the developing device 4, and the resulting toner image is transferred to the recording paper 5a supplied from the recording paper roll 5.

The remaining 1-toner on the surface is removed by a fur brush 6 to clean the surface of the photoreceptor, and the static electricity on the surface of the photoreceptor 1 is removed by the static eliminating corotron 7, and then the surface of the photoreceptor 1 is charged again by the charging corotron 2. let Thereafter, the above operation is repeated. Note that 8 is a transfer corotron, and 9 is a drive 1'' for the photoreceptor 1.

自動的にクリーニングしていた。In such an apparatus, it is actually difficult to completely remove the residual toner on the surface of the photoreceptor 1 with the fur brush 6, and therefore, the [rim] adheres to the tip 3a of the multi-stylus 3, and the multi-stylus 3 function was reduced. For this reason, conventionally, a cleaning device is provided which includes a mechanism for lowering the multi-stylus 3 into the device, and a mechanism for rotating a disk-shaped brush by bringing it into contact with the tip OX 3 a of the multi-stylus. The tip 3a of the multi-stylus 3 was cleaned periodically and automatically by the cleaning device.

故障の要因ともなっていた。However, such conventional multi-stylus 3 cleaning devices have the above-mentioned special mechanism, which increases the size of the electrostatic recording device and causes failures in the electrostatic recording device. .

にしている。In order to achieve the above object, in the present invention, a cleaning means is provided in a part of the photoreceptor of an electrostatic recording device, the cleaning means is moved using the rotation of the photoreceptor, and the cleaning means is connected to a multi-stylus. The tip of the multi-stylus is cleaned every time the multi-stylus passes through the installation section.

As shown in FIG. 3, this cleaning means 10 is made by pasting a material such as paper or cloth on a portion of the upper surface 11a of the photoreceptor 11, for example, on which cilia 10a are implanted. In addition, 12
13 is a main electrode, 13 is an auxiliary electrode, and 14 is a spacer.

At this time, the cleaning means 10 of the photoreceptor 11 passes through the installation part of the multi-stylus 3 disposed oppositely on the surface of the photoreceptor 11, and at this time, the tip portion 3a of the multi-stylus 3 Since brushing is performed by 10, the 1 to ner adhering to the tip portion 3a is removed. Thereafter, the above operation is repeated every time the cleaning means 10 passes the installation part of the multi-stylus 3 as the photoreceptor 11 rotates.
