ABSTRACT:
A device for copying panoramic images includes a screen provided with structure for inclining and fixing the screen. There are defined two like, adjacent sectors successive in height, one of which is transparent and through which the panoramic image to be copied is visible, and the other serving as a graphic board for the reproduction of the panoramic image. The screen is provided with means for transferring the image and preferably a transparent ruler which can move transversely by sliding or by rolling on wheels or bearings, on end guides and, if necessary, also on a central rail in the line of separation between sectors, or without any rail, by means of wheels and threads, and permanently perpendicular to the line of joining between the transparent sector and the opaque sector of the screen. The ruler is provided with a longitudinal slot wherein there are housed the tracking point and the writing point of a tandem having a separation between these elements which coincides approximately with the height of one of the sectors of the screen.
