Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
166 words
A cassette tape recorder comprising a housing body, a cassette chamber in the body, a cassette holder for holding a tape cassette therein and movably mounted on the housing body for movement into and out of the chamber, at least one magnetic head for contacting tape in the cassette when the holder holds a cassette in the chamber, means for driving a magnetic tape in the tape cassette when the holder holds a cassette in the chamber, and a urging means for reversing the tape cassette when held in the cassette holder; said reversing device including actuating means for actuating a holder movement and coupling means coupling the actuating means to the holder for moving the holder out of the chamber in response to a first operation of the actuating means and for rotating the thus moved holder 180° in response to a second operation of said actuating means, whereupon the cassette holder may be reinserted into the chamber and the actuating means again be actuated.
Claim 2
Dependent Claim
166 words
A cassette tape recorder comprising a housing body, a cassette chamber in the body, a cassette holder for holding a tape cassette therein and movably mounted on the housing body for movement into and out of the chamber, at least one magnetic head for contacting tape in the cassette when the holder holds a cassette in the chamber, means for driving a magnetic tape in the tape cassette when the holder holds a cassette in the chamber, and a urging means for reversing the tape cassette when held in the cassette holder; said reversing device including actuating means for actuating a holder movement and coupling means coupling the actuating means to the holder for moving the holder out of the chamber in response to a first operation of the actuating means and for rotating the thus moved holder 180° in response to a second operation of said actuating means, whereupon the cassette holder may be reinserted into the chamber and the actuating means again be actuated.
Claim 3
Dependent Claim
