Abstract
PURPOSE:To allow even the personnel at a remote location from a screen to read easily, not only by projecting the entire reception picture on the screen simply but also by enabling to extend and project exclusively the required part of a transmission picture on the screen with high magnification. CONSTITUTION:In the process that a recording medium 15 is moved in loop, an electrostatic recording head 18 records the electrostatic creeping image corresponding to the received picture signal on the medium 15, and the electrostatic creeping image is developed with a developer 19. The developed reception picture is carried between feeding rollers 4, 5 and stopped at the same position and extended and projected on a screen 31 at the same position. Not only by projecting the entire reception picture on the screen 31, but also narrowering the interval between a front lens 29a and a rear lens 29b and shortening the focus of a projective lens 29, increasing the magnification of projection and moving wheels 26, 28 at a suitable position of rails 25, 27 the required part of the reception picture only is extended with a high magnification and projected on the screen 31.
