ABSTRACT:
A photographic paper magazine in which a detection apparatus faces photographic paper which is unrolled from a roll axially supported by a support member on a magazine body and which is supplied to an outlet. If no photographic paper is detected, the checking apparatus checks the photographic paper winding-up rotation of the support member so as to enable the photographic paper to be drawn out again. When the magazine is opened, the release apparatus cancels checking of the checking apparatus and allows the support member to rotate. The checking apparatus controls the rotation of the support member instead of controlling an intermediate portion of the photographic paper, thereby avoiding application of a substantial resistance to the photographic paper during the drawing-out operation.
