ABSTRACT:
An apparatus for selectively supplies one of a plurality of photosensitive materials having different widths to an exposure unit. The width of the potosensitive material and the exposure unit.
The width of the photosensitive material and a width of the image frame are detected. By comparing the detected widths with each other, a control circuit will select the magazine accommodating the photosensitive material having a width corresponding to that of the image frame. If the selected magazine is already supplying the photosensitive material, it continues to feed it. If not, the control circuit will command to cut off the exposed portion of the photosensitive material, rewind its nonexposed portion by the transfer means, and deliver only the printed photosensitive material remained in the exposure unit. Then, the control circuit selects the photosensitive material whose width corresponds to that of the image frame. Thus, the photosensitive material is changed over automatically according to the width of the image frame of the negative film.
