ABSTRACT:
In order to avoid blocking of the tape travel in a compact cassette deriving from loop formation, an oblique rib is provided between tape cavity and idler roller. The rib ends in close vicinity of the side walls of the cassette leaving only a narrow passage between its free end and the side wall for the tape travel.
