Abstract

Abstract An apparatus for receiving a cassette containing a band-like recording carrier capable of being rewound in a reproduction device, which comprises a cassette, and a band constituting a recording carrier. Holding means are provided for the cassette disposed on opposite sides of the latter and adjustable in a direction towards each other. The sensing plane of the band is disposed within the range of one side of the cassette arranged substantially perpendicularly to the adjustment direction of the holding means. The holding means engaging the sensing side of the cassette have a symmetrical, substantially V-shaped recess, the latter being formed such, that the center of the cassette in relation to the thickness of the cassette upon impression of the cassette into the V-shaped recess assumes coincidence with the plane of symmetry of the V-shaped recess.
