This cassette has at least partly transparent side walls (1a, 1b) and a spine (B) which can be folded open. Guide means (2, 3, 6) for an inserted reel (5) are designed such that they are practically invisible from the outside and the surface of the cassette has no unattractive sinkage points. To this end, the side walls possess, for guiding and centring the reel (5), constrictions (2, 3) at the lower and upper edge. At each lower constriction (3), additional webs (6) are integrally moulded, which webs are segment-shaped, project inwards and are intended to keep the reel offset at a distance (a) from the apex (C) to the spine (B). It is thus achieved that the reel placed in the cassette moves out of the latter by itself when the cassette is opened and can thus be easily removed therefrom. <IMAGE> |
