Abstract
Cassette recorder has a spring member which fits into a depression in the rear edgewall of a cassette to sense whether the cassette is properly positioned for recording. The depression preferably is a conical receptacle, and the spring member has a rounded pawl which fits into the receptacle. The spring member also forces the cassette forwardly against a pair of positioning pins which have inclined faces to force the front of the cassette against the base plate of the recorder thereby positively positioning the cassette in place, and means connected to the spring member enable recording only when the member is fully seated into the depression.
