ABSTRACT:
A container, for example a photographic paper magazine, includes a core about which photographic paper is wound in a form of a roll. A container body contains the roll with the core in a rotatable manner. An outlet slit is formed in the container body and adapted to drawing out the photographic paper. First and second end walls are disposed on the container body, and confronted with respective end faces of the roll. First and second core supports are supported respectively on the first and second end walls, rotatable coaxially, and fitted on respective axial ends of the core. The core supports support the core between the end walls in a rotatable manner. A lock pin is fixedly secured to the first end wall. A hook is disposed on the first core support, is engageable with the lock pin in a resilient manner, and inhibits relative rotation between the hook and the lock pin, to retain the first core support on the first end wall. An arm is displaceable between a free state and a deformed state, and biases the hook. The arm, when the first core support is initially mounted on the first end wall, is bent to the deformed state, to engage the hook with the lock pin. When the first core support is rotated by drawing the photographic paper, the hook is disengaged from the lock pin, to allow the arm to bend back to the free state. The arm moves the hook to a position deviated from the lock pin, and avoids interference with the lock pin.
