Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
174 words
A cassette adapter for tape recorders using relatively large conventional cassettes, the tape recorder including a first capstan shaft with a first pinch roller as well as first delivery and take-up reels, the adapter being substantially equal in size to the large cassettes and being capable of mounting thereon relatively small cassettes, to be played on the tape recorder through the intermediary of the adapter, the small cassette including second delivery and take-up reels, the adapter comprising: a second capstan shaft, a second pinch roller associated with the second capstan shaft, a first power-transmission mechanism for driving the second capstan shaft from said first capstan shaft; a second power-transmission mechanism for selectively driving said second delivery and take-up reels from at least one of said first delivery and take-up reels; and means for moving an operating mechanism into a condition for reproducing recording on the small cassette, said operating mechanism including a first magnetic head for the adapter and said second pinch roller, by means of a reproduction operating member on the tape recorder.
Claim 2
Dependent Claim
174 words
A cassette adapter for tape recorders using relatively large conventional cassettes, the tape recorder including a first capstan shaft with a first pinch roller as well as first delivery and take-up reels, the adapter being substantially equal in size to the large cassettes and being capable of mounting thereon relatively small cassettes, to be played on the tape recorder through the intermediary of the adapter, the small cassette including second delivery and take-up reels, the adapter comprising: a second capstan shaft, a second pinch roller associated with the second capstan shaft, a first power-transmission mechanism for driving the second capstan shaft from said first capstan shaft; a second power-transmission mechanism for selectively driving said second delivery and take-up reels from at least one of said first delivery and take-up reels; and means for moving an operating mechanism into a condition for reproducing recording on the small cassette, said operating mechanism including a first magnetic head for the adapter and said second pinch roller, by means of a reproduction operating member on the tape recorder.
Claim 3
Dependent Claim
46 words
The cassette adapter as defined in claim 1, further comprising an amplifier connected to said first magnetic head, a transfer head connected to said amplifier and to a second magnetic head for the tape recorder, said amplifier being operated through a switch from an electric source.
Claim 4
Dependent Claim
28 words
The cassette adapter as defined in claim 1, wherein said reproduction operating member is said first pinch roller, rotatably supported by a slide plate of the tape recorder.
Claim 5
Dependent Claim
26 words
The cassette adapter as defined in claim 1, wherein said reproduction operating member is an erasing head secured to a slide plate of the tape recorder.
Claim 6
Dependent Claim
26 words
The cassette adapter as defined in claim 1, wherein said reproduction operating member is an upright member secured to a slide plate of the tape recorder.
Claim 7
Dependent Claim
38 words
The cassette adapter as defined in claim 2, wherein said means for moving an operating mechanism is interlocked with said switch, and includes said first magnetic head and said second pinch roller, for actuating said reproduction operating member.
Claim 8
Dependent Claim
72 words
The cassette adapter as defined in claim 1, wherein said reproduction operating member includes a first, manually operable slide plate and a second slide plate loosely interlocked with said first slide plate, a third magnetic head being mounted thereon and effecting at least reproduction, and further comprising a lever inserted between said second slide plate and said first pinch roller, for slidably moving one of said slide plates relative to the other.
Claim 9
Dependent Claim
26 words
The cassette adapter as defined in claim 7, wherein said first slide plate includes a knob for opening and closing an electric-source switch in the adapter.
Claim 10
Dependent Claim
