PURPOSE: To surely load the sheet-shaped photosensitive material in a magazine by providing a plurality of take-out rollers for the side of a leader housing section to a stopper between the leader housing section of a magazine main body and a bladder housing section.

CONSTITUTION: The light shielding bladder 3O of a sheet-shaped photosensitive-material packing body 10 is made up of a bladder section 31 housing the sheet shaped photosensitive material 20, and of a leader section 32 capable of pulling the bladder section 31 to take over the light shielding bladder 30 out of the photosensitive material 20 so as to house it in a magazine 50, and the leader section 32 is made irregular in surface as a whole. A take-over roller 60 and a stopper 56 are integrally moved with the closure 52 of the magazine 50 for the photosensitive material opened, and the photosensitive material packing body 10 is loaded over the exposed take-over roller 59 and a stopper 55. After the end section of the bladder section 31 projected out of the magazine 50 has been opened, when the take-over roller 59 is rotated, following the leader section 32, the take-over rollers 59 and 60 take over the bladder section 31, and the photosensitive material 10 comes out of the opening section of the bladder section 31 so as to be loaded in a bladder housing section 58.
