摘要： The present disclosure is directed to electrostatic recording devices wherein a latent electrostatic image is recorded on a dielectric coated sheet by a stylus array spaced apart from the sheet to form an ionization gap. There is now taught a means to accurately establish the distance between the recording stylus and the dielectric surface upon which the latent image is created. A dielectric sheet containing a conductive layer is passed over a fixed recording head containing an array of styli. The fixed recording head is provided with a source of fliuid which maintains positive pressure in a cavity with the recording head, which cavity has outlets facing the dielectric sheet passing over the head. The length of the gap between the dielectric sheet and the recording head is maintained by the fluid pressure emanating from the head.
摘要翻译： 本发明涉及静电记录装置，其中通过与片材间隔开的触针阵列将静电潜像图像记录在电介质涂层片上，形成电离间隙。 现在教导了一种手段来准确地建立记录触针与其上形成潜像的电介质表面之间的距离。 包含导电层的电介质片通过包含测针阵列的固定记录头。 固定记录头设置有一个流体源，其在记录头中在空腔中保持正压，该空腔具有面向电介质片的出口，该电介质通过头部。 电介质片和记录头之间的间隙的长度由从头部发出的流体压力来维持。

摘要： An erase device for removing residual charges from the photoreceptor of a xerographic type reproduction machine or printer preparatory to recharging, comprising, an elongated rectangular light conducting bar or fiber adapted for disposition with one side thereof in preset spaced relation to the photoreceptor surface; a light impervious cover about the remaining sides of the fiber to prevent escape of light from the interior thereof; an illumination cavity at one end of the fiber; a lamp in the cavity in operative relationship within the fiber end, the lamp and cavity cooperating so that light is discharged by the lamp into the fiber for transmittal axially within the fiber toward the fiber opposite end, portions of the light in the interior of the fiber escaping through the fiber one side to impinge upon the photoreceptor surface and discharge the photoreceptor; the fiber one side being roughened so that the light exit area progressively increases in proportion to the distance from the lamp, the roughened portion enabling the discharge of light through the fiber one side and providing a proportionally increasing light emitting surface in accommodation of the fall off in light intensity as the distance from the lamp increases.In a second embodiment, the fiber is semi-circular in cross section, the rounded portion of the fiber being covered with a cladding material to prevent the escape of light therefrom while permitting the discharge of light from the uncovered flat portion of the fiber, the fiber being positionable with the flat portion thereof in preset spaced relation to the photoreceptor surface, the surface area of the fiber flat portion being roughened to enable the discharge of light from the fiber and progressively increasing in proportion to the distance from the lamp to accommodate fall off in the intensity of the light discharged from the fiber as the distance from the lamp increases.
摘要翻译： 一种用于从静电复印机或用于再充电的打印机的感光体中去除残留电荷的擦除装置，包括：细长矩形导光棒或光纤，其适于以与感光体表面预设间隔的一个位置配置; 围绕光纤的剩余侧面的防透光罩，以防止光从其内部逸出; 纤维一端的照明腔; 在光纤端部内的灯管处于操作关系中，灯和空腔配合使得光被灯排放到纤维中，以在纤维内沿着纤维相对端轴向传播，在内部的光的部分 纤维通过纤维逸出一侧以撞击感光体表面并放电感光体; 光纤一侧被粗糙化，使得光出射面积与与灯的距离成比例地逐渐增加，粗糙部分能够通过光纤一侧排出光并提供成比例增加的发光表面，以适应脱落 在距离灯的距离增加时的光强度。 在第二实施例中，纤维的横截面为半圆形，纤维的圆形部分被覆层材料覆盖，以防止光从其中逸出，同时允许从未覆盖的纤维平坦部分排出光， 纤维的平坦部分可以以与感光体表面预设的间隔的关系定位，纤维平坦部分的表面积被粗糙化，以使得能够从纤维排出光，并与灯的距离成比例地逐渐增加以适应秋天 随着距离灯的距离增加，从光纤放出的光的强度偏离。
