Abstract: An image communication apparatus comprises a memory for storing image data to be transmitted to a multiple of addressees, rearranging unit for rearranging the multiple of addressees in accordance with functions thereof, and transmission unit for sequentially transmitting the image data stored in the memory to the multiple of addressees rearranged by the rearranging unit.

Abstract: There is disclosed a recording/reproducing system comprising an optical system for directing along a path of an electromagnetic radio ray from an object toward a recording medium, and a recording head disposed in the path for generating a charge latent image onto the medium. The feature of the system resides in that the recording head (system) forms the detection region which is not entirely subject to the influence of the electromagnetic radio ray and which is provided in a portion of the charge recording region of the medium, and in that a reproducing system discriminates the polarity of charges or the recording mode of the charge latent image recorded onto the medium by detecting the charges in the dectection region.

Abstract: An apparatus for correcting the quantity of light from an optical printer arranged a plural number of luminous elements therein, which comprises a producing circuit for producing a plural number of timing signals of different pulse widths and output timing, and a combining circuit for combining the timing signals according to the correcting data, thereby driving the respective luminous elements based on a correcting signal obtained by combination thereof.

Abstract: An apparatus for recording a binary image of a printed circuit pattern on photosensitive material. First and second rows of recording spots scan the photosensitive material. The second row is shifted by a length corresponding to approximately half the diameter of the recording spots. Each of the recording spots covers an area equal to approximaqtely four pixels. Whether a pixel is to be exposed is determined on the basis of a logical sum or product of data corresponding to four adjacent pixels.
