DEVICE FOR INSPECTING TRANSMISSION AND REFLECTION PLATE

摘要

PURPOSE:To photograph an original plate film to be inspected by both transmission and reflection and to obtain a plate inspecting device for both transmission and reflection by providing a light source below an original rack and to the moving rack of a camera. CONSTITUTION:Two film racks 10 and 12 where original plate films 2 and 4 are mounted are constituted by arranging a light diffusing plate below a transparent glass plate and light sources 16 and 18 which are connected to a DC stabilized power source so as to light transmission type original films 2 and 4 are arranged below the film racks. Further, the moving rack 50 to which two TV cameras 30 and 32 are fitted is arranged above the film racks 10 and 12 and placed on a Y-directional moving rack 48 which moves only in a Y direction so that the moving rack for the cameras is movable in an X direction; and this rack 50 is movable freely in the X and Y directions on the film racks 10 and 12 manually with a handle 52. Consequently, the two TV cameras 30 and 32 photograph optional corresponding positions of the original plate films 2 and 4.
