In a receiver cassette for web material (1), for example for an exposed film web material, the web material exits out of an optical flying spot scanning device (2). The web material (1) passes into an entrance slot (13a) a light-sealed casing (13). A rotatably supported hub (5) of a spool is disposed in the interior (13b) of the light-sealed casing (13). In order to increase the receiving capacity of web material lengths and in order to allow a fully automatic winding formation there is provided a motor-driven hub (5) of the spool. The hub (5) of the spool exhibits an about centric clamping slot (14). When a clamping slot entrance opening (16) of the hub (5) of the spool is directed substantially in upward direction in a base position (15) the hub (5) of the spool is furnished with position-defining means (18) in the end regions (17) of the hub (5) of the spool. The position-defining means (18) maintain the hub (5) of a spool in rest position in the base position (15). The position-defining means (18) can be switched into a non-interfering state by winding up of the web material (1).
