Abstract: Cassette, designed to receive a stack of flat objects such as diskettes and compact discs, which cassette comprises a box part and a cover part, which can be fitted one inside the other in a sliding fit. In one of the parts, moreover, an element is present having a step-shaped series of supporting points, by means of which the objects located in the cassette lie mutually aligned in a first defined mutual position--storage position--of the box part and cover part, whilst in a second defined mutual position--usage position--they assume a height which steadily increases in the stack. The box part and cover part are mutually hinged near one of the corners. The side wall of the box part which is situated next to the hinge axis is provided with an opening at a short distance from the bottom wall, and the element having the step-shaped supporting points is fitted to the side wall of the cover part between the hinge axis and the opening in the box part.
