    • A picture image recording apparatus includes an image-forming device for forming a light-shielding image on a light-transmissive sheet, an exposure device for exposing a photosensitive recording medium to light through the light-transmissive sheet to form a latent image corresponding to the light-shielding image on the photosensitive recording medium, and either a control device for controlling the image-forming means to form a light-shielding image on a next light-transmissive sheet area to be exposed, during exposure operation by the exposure means, or a standby device for holding the light-transmissive sheet with the image formed thereon in a standby condition. While the photosensitive recording medium is being exposed to light through the light-transmissive sheet, a next light-shielding image to be exposed can successively be formed on the light-transmissive sheet. Therefore, the time required to record picture images can be shortened.

    • An electrophotographic printer having a movable image developing device for forming a visible image on a photosensitive sheet. The printer contains a sheet handling unit having a light receiving portion for feeding the photosensitive sheet to the light receiving portion and for discharging the same therefrom; an exposure unit containing a cathode ray tube which projects its displaying image onto the photosensitive sheet when the sheet is at the light receiving portion so as to produce an electrostatic latent image on the sheet; and, the image developing device selectively movable between first and second positions, the developing device containing a developer for developing the electrostatic latent image into the visible image with the developer. A copying apparatus is also disclosed whose CRT in an exposure unit has a scrolling function. The copying apparatus also provides a control for controlling scrolling speed in synchronization with the feeding speed of the sheet. The CRT used in the above described device has a screen whose edge portion provides brightness higher than that of the remaining portion.
    • 一种具有用于在感光片上形成可见图像的可动图像显影装置的电子照相打印机。 打印机包括一个纸张处理单元,该纸张处理单元具有用于将感光片馈送到光接收部分并将其从其中排出的光接收部分; 曝光单元,其包含阴极射线管,当所述片处于所述光接收部分时,所述阴极射线管将其显示图像投射到所述感光片上,以在所述片材上产生静电潜像; 并且,所述图像显影装置可选择性地在第一和第二位置之间移动,所述显影装置包含用显影剂将静电潜像显影成可见图像的显影剂。 还公开了一种在曝光单元中的CRT具有滚动功能的复印装置。 复印装置还提供与片材的进给速度同步地控制滚动速度的控制。 在上述装置中使用的CRT具有边缘部分提供高于剩余部分的亮度的屏幕。
