ABSTRACT:
A device for receiving a tape of material characterized by a closed case having a light-tight chamber in communication with the exterior of the chamber by a channel provided with light shutters, a tape supporting arrangement comprising a plurality of reels mounted for rotation in the chamber on an axle, at least one spring element for continuously pressing a tape onto the reels as it is fed into the chamber, and a guiding device disposed on the chamber for laterally guiding the tape as it is being wound on the reels. In order for the device to handle tapes of different widths, the guiding device includes a pair of disks disposed at opposite ends of the plurality of reels and at least one retractable guide member pivotably mounted on the axle between a pair of reels to move between a retracted position withdrawn within the circumference of the reels to an extended position with a portion extending beyond the periphery of the reels.
