Abstract
Abstract A cassette loading device in a cassette tape recorder has a cassette housing adapted to accommodate a cassette extractably inserted thereinto and to move between a cassette extraction position and a cassette loading space. The cassette loading device comprises a cassette guiding member disposed to face the cassette loading space to guide the cassette into the cassette loading space. The cassette guiding member has inclined guide parts which function, in a case where the cassette loading operation is carried out with the cassette in a state wherein it is not completely accommodated within the cassette housing, to guide the rear part, as viewed in the insertion direction, of the cassette at an intermediate point in the entering movement of the cassette housing into the cassette loading space thereby to press the cassette fully and positively into the cassette housing.

Claim 1
Independent Claim
221 words
A cassette loading device in a cassette tape recorder having a cassette housing adapted to receive and accommodate a cassette which is extractably inserted thereinto, said housing moving between a cassette extraction position and a cassette loading space, said cassette loading device comprising a pair of flanges mounted on a chassis, two pair of support arms having top ends which are pivotally connected to the cassette housing and bottom ends which are connected to said pair of flanges so that the cassette housing is supported and substantially vertically displaced between the cassette extraction position and the cassette loading space, and a cassette guiding member having a curved surface which is disposed to face said cassette loading space in order to guide the cassette into said cassette loading space, said curved surface having a pair of protruding and inclined guide ribs which function, during a cassette loading operation with the cassette in a state wherein it is not completely accommodated within the cassette housing, to guide the rear part as viewed in the insertion direction of the cassette at an intermediate point during the entering of the cassette housing wherein upon completion of the cassette loading operation, the cassette guiding member does not contact the cassette into the cassette loading space to press the cassette fully and positively into the cassette housing.
