    • An electonic copying machine for making a hard copy of a remote original comprises a housing and an image pick-up unit pivotally mounted on the housing for vertical swinging movement between a raised use position and a lowered non-use position. In the housing, there are a scanner for scanning the remote original with a line of light projected through a transparent window plate, a recording head and image recording paper. In the image pick-up unit, there are a lens for forming a line image of the scanned remote original on the recording paper, a line image sensor for reading the line image formed thereon by the lens to provide line image signals according to which the image recording head records and image on the recording paper, shifting the line image sensor by a predetermined pitch in a direction perpendicular to the longitudinal direction of the line image sensor. When the image pick-up unit is folded down, the transparent window plate is covered by the image pick-up unit and the lens is received in a space formed in a corner of the housing and the electronic copying machine then has the shape of a generally rectangular box.

    • A copying machine for making a hard copy of an original comprises an image sensor for reading an image of the original to provide image signals, a memory for memorizing the image signals after or before processing the image signals for necessary corrections, and a printer for printing an image on a copying sheet according to the image signal after image processing. Preferably, a thermal printing head and a heat sensitive sheet are used. The copying machine is compact and either is incorporated in a portable overhead projector or is used as a writing board copy machine. In the former case, the image sensor is disposed in a supporting arm for supporting an image projection lens assembly above a base section of the overhead projector on which a transparent original is placed. The image sensor reads a reflecting original to provide image signals and the thermal printing head prints a mirror image of the reflecting original on a transparent heat sensitive sheet according to the image signals provided by the image sensor, thereby providing a transparent secondary original instantly for projection. In the latter case, the machine includes a pattern projector for projecting a light pattern which will be deformed on the remote original according to position of the copying machine, whereupon a correcting circuit provides a correction signal. The heat sensitive sheet is formed with indicia near front and rear diagonally opposite edges, symmetrically with respect to the center of the sheet, to indicate at least the surface of the sheet to which a heat sensitive material layer is applied.
    • 用于制作原件的硬拷贝的复印机包括用于读取原稿的图像以提供图像信号的图像传感器,用于在处理用于必要校正的图像信号之前或之前存储图像信号的存储器和用于打印的打印机 根据图像处理后的图像信号在复印纸上的图像。 优选使用热敏打印头和热敏片。 复印机是紧凑型的,或者被并入便携式高架投影仪中,或者被用作书写纸复印机。 在前一种情况下,图像传感器设置在支撑臂中,用于将投影透镜组件支撑在放置有透明原稿的高架投影仪的基部上。 图像传感器读取反射原稿以提供图像信号,并且热敏打印头根据由图像传感器提供的图像信号将反射原稿的镜像打印在透明热敏纸上,从而立即提供透明的二次原稿用于投影 。 在后一种情况下,机器包括用于根据复印机的位置投射将在远程原稿上变形的光图案的图案投影仪,因此校正电路提供校正信号。 感热片形成有相对于片材的中心对称的前后对角相对边缘附近的标记,至少表示施加有热敏材料层的片材的表面。
