ABSTRACT:
A microcamera for photographing the image of an original document on a film, with an aperture for determining a photographing area. The size of the aperture is variable in accordance with a document size by moving an end edge of the aperture adjacent a film supply reel with an end edge thereof adjacent to a film takeup reel fixed. Aperture size variations effected in this manner is free from superposition of an image on a preceding image when the photographing area is enlarged from half size to full size, for example. Conversely, when the photographing area is reduced from fullsize to half size, a space between adjacent images may be the same as when the photographing area is not reduced.
