ABSTRACT:
A reproduction camera having a movable table which at two adjacent corners is guided in two vertical guides on the frame of the camera and moved by an endless cord which is passed over cord pulleys arranged above and below said guides, the endless cord being further passed over a winding drum and connected to the said movable table in such manner that the two connecting points are moved in the same direction when the cord is moved, whereby a very exact translatory movement of the table is obtained by a very simple mechanism which is easy to manufacture and to operate.
