Abstract

PURPOSE: To obtain the hard copy of good appearance based on the microfilm by exposing recording portion on one frame of the microfilm, shielding light only the recording portion and uniformly exposing one frame of the microfilm.
CONSTITUTION: The document 1 to be photographed is placed on a support table 4 and the document is lighted by a lighting means 11. After this, the portion 6 of the document 1 is photographed and recorded in one frame of a microfilm by a photographing head 5. Thence, a maks 8 is put in the optical path from the photographing head 5 and with the portion 2 being held shaded light, the one frame of the microfilm is exposed sufficiently uniformly by a lighting means 12. By such operation, the recording of the only 2 of the document 1 remains on the microfilm and the rest are uniformly exposed and appear black. In this way, only the information appears white in the black ground on the microfilm with the simple construction and therefore the hard copy of good appearance may be made based on this microfilm.
