Abstract
Abstract A DEVICE FOR THE MAGAZINE WHICH TRANSMITS FILM TO A FILM EXCHANGER IS CHARACTERIZED IN THAT THE MAGAZINE IS PROVIDED WITH A FILM HOLDER WHEREIN SEPARATE FILM SHEETS ARE HELD BY SPRING PRESSURE BETWEEN DISCS FORMING A PILE. AN ARM ACTUATED BY THE FILM EXCHANGER HAS A CLAW PENETRATING INTO A RECESS OF THE DISC PILE IN SUCH MANNER THAT THE CLAW ENGAGES A FILM SHEET AT ITS REAR EDGE AND PULS IT OUT THROUGH A SLIT IN THE MAGAZINE IN THE DIRECTION OF THE ILLUMINATED FIELD OF THE FILM EXCHANGER. GUIDES ARE LOCATED IN THE MAGAZINE AT OPPOSED SIDE EDGES OF THE FILM SHEETS. THESE GUIDES HOLD DOWN THE SHEET EDGES AND IMPART TO THE FILM SHEETS A CURVED SHAPE AND GREATER STABILITY.
